本发明涉及烟丝剪切领域，特别涉及一种压拉式滑切型烟丝铡切装置。The invention relates to the field of cut tobacco cutting, and in particular to a pressure-pull type sliding cut tobacco cutting device.
背景技术Background technique
烟丝在制作过程中通常需要相应的设备来改变烟丝的长短结构，烟丝长短达不到工艺要求，在卷烟卷制过程中会造成竹节烟，严重影响卷烟的品质。During the production process of shredded tobacco, corresponding equipment is usually required to change the length and structure of the shredded tobacco. If the length of the shredded tobacco does not meet the process requirements, bamboo cigarettes will be formed during the cigarette rolling process, seriously affecting the quality of the cigarettes.
现有的烟丝制作设备主要分为以下三种，第一种采用切丝机刀板进行定长截断，第二种采用带有速度差的滚动刺辊、刀盘进行旋打或旋切，第三种是旋转动刀与左右两定刀剪切。采用刀板定长截断方式是将长丝截短了，但短丝截的更短；相对而言采用带有速度差的滚动刀盘进行旋切及动刀与定刀配合形成压推铡切的设备优点较多。The existing shredded tobacco production equipment is mainly divided into the following three types. The first type uses a shredder blade for fixed-length cutting, the second type uses a rolling licker-in with a speed difference and a cutter disc for rotary beating or rotary cutting. The three types are shearing with a rotating movable knife and two fixed knives on the left and right. The fixed-length cutting method of the blade is used to cut the filament into shorter length, but the short yarn is cut even shorter; relatively speaking, a rolling cutter with a speed difference is used for rotary cutting and the movable knife and the fixed knife cooperate to form a push guillotine cutting. The equipment has many advantages.
1、中国发明专利“一种卷烟烟丝长丝切短机”，公开日为2015年06月03日，采用了一种带有速度差的圆形刀盘进行旋切。虽然带有速度差的滚动刀盘进行旋打或旋切的烟丝设备一定程度上降低了烟丝的长丝率，但分切方式仍是向来料处压堆式剪切，这和人手握剪刀一样，两刀刃从根部开剪向外压堆物料，积累多了闷车。具体是当两相对的切刀在相对旋转时，一切刀为高速刀盘组，另一切刀为低速刀盘组，两刀盘组的切刀相对应，当两刀盘组在进行相对运动时，两刀盘的切刀进行周期性的相互作用和分离以完成剪切动作，当长烟丝落于两刀盘组之间时，高速刀盘组撕扯长烟丝并完成切割过程。在上述的剪切过程中，对应的切刀之间从开始接触到相互脱离的过程构成了进料的剪切路径，由于快刀盘是每分钟1000米以上的线速度旋转，产生的正压风让烟丝随着刀头旋转，加上烟丝来料的多少、水分不能精准控制，以及使用刀刃磨损，位于切刀间的烟丝较大存在不能立即切断，造成向进料方向推移或随刀片旋转而逐步积累在两刀头之间，并导致堵塞、顿刀、闷车的事实。为了避免上述现象发生，不得不采用更大功率的电机使的切刀更有力，以增强切刀的通过性，但是无疑这一方法并未从根本上解决上述问题，也造成烟丝造碎增加，装机更加的耗能。1. The Chinese invention patent "A cigarette filament cutting machine" was published on June 3, 2015. It uses a circular cutterhead with a speed difference for rotary cutting. Although the tobacco equipment with a rolling cutterhead with a speed difference for rotary beating or rotary cutting reduces the filament rate of the tobacco to a certain extent, the cutting method is still a pile-type shearing towards the incoming material, which is the same as scissors held by a human hand. , the two blades cut from the root and press the material outward, accumulating too much stuff. Specifically, when two opposite cutting knives are rotating relative to each other, one cutting knife is a high-speed cutterhead group, and the other cutting knife is a low-speed cutterhead group. The cutting knives of the two cutterhead groups are corresponding. When the two cutterhead groups are moving relative to each other, , the cutters of the two cutterheads interact and separate periodically to complete the shearing action. When the long cut tobacco falls between the two cutterhead groups, the high-speed cutterhead set tears the long cut tobacco and completes the cutting process. In the above-mentioned shearing process, the process from the beginning of contact to the separation between the corresponding cutters constitutes the shearing path of the feed. Since the fast cutter disc rotates at a linear speed of more than 1000 meters per minute, the positive pressure wind generated Let the shredded tobacco rotate with the cutter head. In addition, the amount of incoming tobacco and the moisture content cannot be accurately controlled, and the blade is worn. The large amount of shredded tobacco between the cutters cannot be cut immediately, causing it to move in the feeding direction or to rotate with the blade. It gradually accumulates between the two cutter heads and leads to clogging, cutter stalling, and machine boredom. In order to avoid the above phenomenon, a higher-power motor has to be used to make the cutter more powerful to enhance the passability of the cutter. However, there is no doubt that this method does not fundamentally solve the above problems and also causes an increase in shredded tobacco. Installation consumes more energy.
2、中国实用新型专利“低能耗防造碎烟丝剪切装置”，授权日期2018年7月5日，该专利比带有速度差的双滚动刀盘进行旋打或旋切的烟丝设备，明显节能和降低烟丝的造碎率。但由于该专利定刀切刃是平行于动刀盘中心水平线下倾钭安装，旋转刀盘刀刃是平行于动刀盘中心水平线上倾钭制造，形成压切，或叫砍切。由于快刀盘是每分钟1000米以上的线速度旋转，产生的正压风让烟丝随着刀头旋转，十公分长的切刀刃，切烟丝时只用切刀头部一至三公分，在来料水份少、料层薄和刀刃锋利时切断效果好，如果来料水份变大、动定刀刃磨钝或烟丝厚度超过两定刀间距，烟丝积累在定刀根部上面与仓壁连接处，易出现顿刀易至“闷车”。2. China’s utility model patent “Low Energy Consumption Preventing Shredded Tobacco Shearing Device”, granted on July 5, 2018. This patent is obviously more powerful than a tobacco cutting device with a double rolling cutterhead with a speed difference for rotary beating or rotary cutting. Save energy and reduce the breakage rate of shredded tobacco. However, because the patented fixed knife cutting edge is tilted and installed parallel to the center horizontal line of the movable cutterhead, the rotating cutterhead blade is tilted parallel to the center horizontal line of the movable cutterhead, forming a pressure cut, or chopping. Since the fast cutter disc rotates at a linear speed of more than 1,000 meters per minute, the positive pressure air generated causes the cut tobacco to rotate with the cutter head. The ten-centimeter long cutting blade only uses one to three centimeters from the head of the cutter when cutting the cut tobacco. The cutting effect is good when the moisture content of the material is low, the material layer is thin, and the blade is sharp. If the moisture content of the incoming material becomes large, the blade of the movable fixed knife is blunt, or the thickness of the cut tobacco exceeds the distance between the two fixed knives, the cut tobacco will accumulate at the connection between the root of the fixed knife and the warehouse wall. It is easy to get stuck in the knife and become "bored" in the car.
总之，现有技术存在如下问题需及时解决：一、传统烟丝双刀盘旋转剪切和动刀盘配定刀组旋转压切存在将烟丝推向来料及仓壁处，积累造成闷车、顿刀以及电耗较高的问题；二、因刀盘高速旋转风力使烟丝仅随刀头旋转，十公分长的切刀刃，切烟丝时只用切刀头部一至三公分问题。In short, the existing technology has the following problems that need to be solved in time: 1. The traditional double-cutter rotary shearing of cut tobacco and the rotating cutter head with fixed cutter set push the cut tobacco to the incoming material and the warehouse wall, which accumulates to cause stuffy car and knife stalling. And the problem of high power consumption; 2. Because the cutter head rotates at high speed and the wind force causes the cut tobacco to rotate only with the cutter head, the ten centimeter long cutting blade only uses one to three centimeters of the cutter head when cutting the cut tobacco.

本发明的优点是：The advantages of the present invention are:
1、采用一组旋转刀和一组定刀，实现烟丝的铡切，电机所需的功率大大降低。1. A set of rotating knives and a set of fixed knives are used to cut tobacco, and the power required by the motor is greatly reduced.
2、优化设计旋转刀与定刀的安装结构，旋转刀与定刀片的接触由定刀片的根部开始并逐步倾斜向下，利用旋转刀产生的力带动物料沿定刀片的刀刃倾斜向下滑切，使得动刀头压拉烟丝从定刀刃根部开始，沿定刀刃向下滑切，最终将物料切断，延长物料的剪切路径，避免物料堆积造成的闷车顿刀问题，充分保证物料的切割时间。2. Optimize the design of the installation structure of the rotating knife and the fixed blade.

Install the fixed knife with an inclined angle, that is, the upper part of the fixed knife root and the center of the movable cutter head are in a horizontal line, and the fixed knife head is tilted downward by 20 degrees to 40 degrees to solve the problem when the blade is not sharp and the thickness of the incoming material exceeds the distance between the two fixed knives. If the knife cannot cut with one stroke, then move the knife to drag the material along the fixed blade to cut smoothly. Under the same conditions, the material will not accumulate until it becomes "stuffy".

The "upper" and "lower" that appear are based on the positions shown in the specific drawings and do not represent the specific installation positions in reality.
如图1、图2、图3、图4所示，压拉式滑切型烟丝铡切装置，它包括机架300部分，机架300用于安装烟丝铡切装置中的各部件，机架300由刚性杆焊接而成并形成框架式的结构；机架300的上方用于安装第一刀片组、第二刀片组；第一刀片组为旋刀组100，旋刀组100的刀片为旋转刀102，各旋转刀102包括与旋转轴101固定配合的轮毂部103，还包括均匀圆周分布于轮毂部103外周面的若干旋转刀片104；第一刀片组通过压紧螺丝安装在旋转轴101上，旋转轴101与各旋转刀102之间相对固定，而旋转轴101通过轴承组件与机架300进行固定，旋转轴101的一端通过传动装置400与电机连接，电机经传动装置400驱动旋转轴101转动；而第二刀片组通过刀架201安装在机架300上，第二刀片组的刀片为定刀片202，各定刀片202通过安装在机架300上的刀架201固定安装，各所述定刀片202为长条形结构，刀架201上设有与第二刀片组各刀片配合的安装槽，各第二刀片组的各刀片通过螺栓与刀架201拆卸式固定连接；为了避免旋转刀102相对第二刀片组各刀片运动时物料向上或向进料方向移动，第二刀片组的各刀片倾斜向下，也即当各旋转刀102与第二刀片组的刀片接触时，旋转刀片104的刀刃、初始接触位置、第二刀片组刀片的刀刃所形成的角的朝向与物料的进料方向相反，即倾斜向下，这一结构保证当旋转刀102与第二刀片组铡切时，物料能够在旋转刀102的作用下沿第二刀片组刀刃方向移动，在并上述过程中完成铡切。As shown in Figures 1, 2, 3, and 4, the push-pull sliding cut tobacco cutting device includes a frame 300. The frame 300 is used to install various components of the tobacco cutting device. The frame 300 is welded by rigid rods and forms a frame structure; the top of the frame 300 is used to install the first blade group and the second blade group; the first blade group is the rotary knife group 100, and the blades of the rotary knife group 100 are rotating Knife 102, each rotary knife 102 includes a hub part 103 fixedly matched with the rotating shaft 101, and also includes a plurality of rotating blades 104 evenly distributed on the outer circumferential surface of the hub part 103; the first blade group is installed on the rotating shaft 101 through compression screws. , the rotating shaft 101 and each rotating knife 102 are relatively fixed, and the rotating shaft 101 is fixed to the frame 300 through the bearing assembly. One end of the rotating shaft 101 is connected to the motor through the transmission device 400, and the motor drives the rotating shaft 101 through the transmission device 400. Rotate; and the second blade group is installed on the frame 300 through the knife holder 201, the blades of the second blade group are fixed blades 202, and each fixed blade 202 is fixedly installed through the knife holder 201 installed on the frame 300, each of which The fixed blade 202 has a long strip structure, and the tool holder 201 is provided with a mounting slot that matches each blade of the second blade group. Each blade of each second blade group is detachably and fixedly connected to the tool holder 201 through bolts; in order to avoid rotating the knife When the blades of the second blade group 102 move relative to each other, the material moves upward or in the feeding direction, and each blade of the second blade group is tilted downward. That is, when each rotating blade 102 contacts the blade of the second blade group, the rotating blade 104 The direction of the angle formed by the blade, the initial contact position, and the blade of the second blade group is opposite to the feeding direction of the material, that is, tilted downward. This structure ensures that when the rotating knife 102 cuts with the second blade group, The material can move along the blade direction of the second blade set under the action of the rotating knife 102, and the cutting is completed in the above process.
如图2、图3所示，传动装置采用带传动，也即旋转轴101的端部安装与传动带配合的皮带轮401，同时为了平衡旋转轴101的两端以及为了增强旋转轴101在旋转过程中的稳定性，在旋转轴101的另一端安装有惯性轮402。As shown in Figures 2 and 3, the transmission device adopts belt transmission, that is, the end of the rotating shaft 101 is installed with a pulley 401 that matches the transmission belt. At the same time, in order to balance the two ends of the rotating shaft 101 and to enhance the rotation of the rotating shaft 101 during the rotation For stability, an inertial wheel 402 is installed at the other end of the rotating shaft 101.
如图2、图3所示，各旋转刀102在旋转轴101上的安装方式，根据具体工况环境进行调节，在本方案中为了达到更好的切断效果以及为了增强旋转刀102的通过性，相邻旋转刀102在旋转轴101上交错安装，以与旋转刀102端面平行的端面作为投影面，各旋转刀102的旋转刀片104向投影面投影，投影面上的相邻的旋转刀片104间角度均匀分布；如图4所示，各旋转刀102上的旋转刀片104为三个，位于同一旋转刀102上的相邻旋转大片间角度为120°，位于不同旋转刀102上的相邻旋转刀片104间角度为40°。As shown in Figures 2 and 3, the installation method of each rotary knife 102 on the rotating shaft 101 can be adjusted according to the specific working conditions. In this solution, in order to achieve a better cutting effect and to enhance the passability of the rotary knife 102 , adjacent rotating blades 102 are installed staggeredly on the rotating shaft 101, with the end surface parallel to the end surface of the rotating blade 102 as the projection surface, the rotating blade 104 of each rotating blade 102 projects to the projection surface, and the adjacent rotating blade 104 on the projection surface The angles between them are evenly distributed; as shown in Figure 4, there are three rotating blades 104 on each rotating knife 102. The angle between adjacent rotating blades located on the same rotating blade 102 is 120°, and the angle between adjacent rotating blades located on different rotating blades 102 is 120°. The angle between the rotating blades 104 is 40°.
如图2、图3、图4所示，为了更好的实现物料沿定刀片202安装方向移动，选择将刀架201位于旋转轴101的中心线斜下方，各定刀片202的与水平面的夹角可选则以下角度18°、20°、30°、35°、40°。As shown in Figures 2, 3, and 4, in order to better realize the movement of materials along the installation direction of the fixed blades 202, the tool holder 201 is positioned obliquely below the center line of the rotating shaft 101, and the clamping between each fixed blade 202 and the horizontal plane is The optional angles are 18°, 20°, 30°, 35°, and 40°.
如图2、图3、图4所示，各定刀片202的与对应的旋转刀片104的初始接触位置位于定刀片202刀刃的根部，且由定刀片202刀刃部、对应旋转刀片104刀刃部、初始接触位置形成的角为倾斜向下，上述的结构尽可能的利用定刀片202的刀刃，以保证物料有足够的铡切路径，充分保证物料在沿刀刃滑动时完成剪切。As shown in Figures 2, 3, and 4, the initial contact position of each fixed blade 202 with the corresponding rotating blade 104 is located at the root of the blade of the fixed blade 202, and is composed of the blade of the fixed blade 202, the blade of the corresponding rotating blade 104, The angle formed by the initial contact position is inclined downward. The above-mentioned structure uses the blade of the fixed blade 202 as much as possible to ensure that the material has a sufficient cutting path and fully ensures that the material is sheared when sliding along the blade.
如图1至图4所示，旋转刀102在设定的转速下进行匀速转动，转动过程中与定刀片202产生周期性的铡切动作，物料的进料口位于旋转刀102和定刀片202之间，当物料进入时，随着旋转刀102的不断旋入，物料在旋转刀102的作用下在定刀片202的刀刃部完成铡切；这一过程中，当物料湿度较小、且刀片较锋利时，物料直接完成剪切，而当物料湿度较大剪切不易时，旋转刀102拖拽物料在定刀片202上进行滑切，同样能够达到较好的铡切效果；上述的铡切的过程中，通过增长物料的铡切路径的手段来获得剪切效果，并不需要增强电机的功率；本发明仅采用一组旋转刀102和一组定刀实现烟丝的铡切，减少了电机的使用，而且通过优化设计旋转刀102与定刀的安装结构，延长物料的铡切路径，避免物料堆积造成的闷车顿刀问题，旋转刀102与定刀片202的接触由定刀片202的根部开始并逐步倾斜向下，利用旋转刀102产生的力带动物料沿定刀片202的刀刃倾斜向下滑切，当物料不易进行及时切断时，充分保证物料的切割时间，使得最终物料能够完成切断，电机所需的功率大大降低。As shown in Figures 1 to 4, the rotary knife 102 rotates at a constant speed at a set speed. During the rotation, it produces periodic cutting actions with the fixed blade 202. The material inlet is located at the rotary knife 102 and the fixed blade 202. When the material enters, as the rotating knife 102 continues to rotate, the material is cut at the blade of the fixed blade 202 under the action of the rotating knife 102; during this process, when the humidity of the material is low and the blade When the material is sharper, the material is sheared directly. When the material has high humidity and is difficult to cut, the rotating knife 102 drags the material to slide on the fixed blade 202, which can also achieve a better guillotine cutting effect; the above guillotine cutting In the process, the shearing effect is obtained by increasing the cutting path of the material, and there is no need to increase the power of the motor; the present invention only uses a set of rotary knives 102 and a set of fixed knives to achieve cutting of shredded tobacco, reducing the need for motors By optimizing the installation structure of the rotary knife 102 and the fixed knife, the cutting path of the material is extended to avoid the problem of stuffy lathe cutting caused by material accumulation. The contact between the rotary knife 102 and the fixed blade 202 is determined by the root of the fixed blade 202 Start and gradually tilt downward, and use the force generated by the rotating knife 102 to drive the material to slide downward along the edge of the fixed blade 202. When the material is not easy to be cut off in time, the cutting time of the material is fully guaranteed so that the final material can be cut off. The motor The power required is significantly reduced.
