内衬纸卷筒装夹支架及装夹方法Clamping bracket and clamping method for lining paper roll

技术领域technical field

本发明涉及烟草机械领域，尤其涉及一种内衬纸卷筒装夹支架及应用内衬纸卷筒装夹支架进行内衬纸卷筒装夹的方法。The invention relates to the field of tobacco machinery, in particular to a bracket for clamping an inner-lining paper roll and a method for clamping the inner-lining paper roll by using the bracket for clamping the inner-lining paper roll.

背景技术Background technique

如图1所示，内衬纸转塔a1上有一对内衬纸卷筒装夹支架a2，分别在图中高、低两个位置上。对于内衬纸卷筒装夹支架a2来说，如图2所示，主要由卡圈a7、滑块a8、弹簧a3、座a4、夹紧块a5、芯轴a6等部分组成。内衬纸卷筒装夹支架a2的左端有一个单作用气缸（图中未示出），能够控制着内衬纸卷筒装夹支架a2对内衬纸卷筒锁紧与松开。As shown in Figure 1, there is a pair of inner lining paper reel clamping brackets a2 on the inner lining paper turret a1, which are respectively at the high and low positions in the figure. For the inner liner paper reel clamping bracket a2, as shown in Figure 2, it is mainly composed of collar a7, slider a8, spring a3, seat a4, clamping block a5, mandrel a6 and other parts. There is a single-acting cylinder (not shown in the figure) at the left end of the inner lining paper reel clamping bracket a2, which can control the inner lining paper reel clamping bracket a2 to lock and release the inner lining paper reel.

当一卷耗尽的内衬纸卷筒在内衬纸转塔a1的带动下，转至低位位置停顿后，单作用气缸开始工作，滑块a8在气缸的推动下向右侧运动，带动芯轴a6克服弹簧a3的弹簧力向右侧推进，夹紧块a5镶嵌在芯轴a6上，随着芯轴a6向右移动，夹紧块a5向下收回，松开内衬纸卷筒，此时可取下内衬纸卷筒装夹支架a2上耗尽的内衬纸卷筒。When a roll of exhausted inner lining paper is driven by the inner lining paper turret a1, turns to the low position and pauses, the single-acting cylinder starts to work, and the slider a8 moves to the right under the push of the cylinder, driving the core The shaft a6 overcomes the spring force of the spring a3 and advances to the right, and the clamping block a5 is embedded on the mandrel a6. As the mandrel a6 moves to the right, the clamping block a5 is retracted downward, and the lining paper roll is released. The exhausted inner lining paper roll on the clamping bracket a2 of the inner lining paper roll can be removed at the same time.

当内衬纸卷筒取下后，单作用气缸保持不动，紧压滑块a8，使与其连接的芯轴a6和夹紧块a5处于停顿状态，内衬纸卷筒装夹支架a2制动，便于新内衬纸卷筒装载。当新的内衬纸卷筒装在内衬纸卷筒装夹支架a2后，单作用气缸收回，在弹簧a3作用下，推动芯轴a6向左运动与芯轴a6相连的夹紧块a5向外运动，当滑块a8接触卡圈a7后，芯轴a6的运动停止，夹紧块a5锁紧卷筒。When the inner liner paper roll is removed, the single-acting cylinder remains stationary and presses the slider a8 so that the mandrel a6 and the clamping block a5 connected to it are at a standstill, and the inner liner paper roll clamping bracket a2 brakes , for easy loading of new lined paper rolls. When the new inner lining paper roll is mounted on the inner lining paper roll clamping bracket a2, the single-acting cylinder retracts, and under the action of the spring a3, pushes the mandrel a6 to move to the left and the clamping block a5 connected with the mandrel a6 When the slider a8 touches the collar a7, the movement of the mandrel a6 stops, and the clamping block a5 locks the reel.

虽然内衬纸使用部门对内衬纸卷筒的内直径有明确规定（例如75mm），但由于现今使用的内衬纸卷筒芯都为硬质纸芯，在纸芯的制造过程中，往往会存在大小差异，如果制造的纸芯直径过大，则夹紧块难以夹紧内衬纸卷筒，如果纸芯直径过小，则又会造成纸卷筒装夹不上。Although the inner diameter of the inner lining paper reel is clearly stipulated by the department using the inner lining paper (for example, 75mm), since the inner lining paper reel cores used today are all hard paper cores, in the manufacturing process of the paper cores, often There will be size differences. If the diameter of the manufactured paper core is too large, it will be difficult for the clamping block to clamp the inner lining paper roll. If the diameter of the paper core is too small, the paper roll will not be able to be clamped.

Thesecond cylinder 5 is used to control themandrel 7 to move a certain distance to the other side (ie, the left side in FIG. 3 ), and then drive theclamping block 3 to extend. In another embodiment, thefirst cylinder 12 and thesecond cylinder 5 can also be double-acting cylinders. Since the single-acting cylinder satisfies the relatively high extension action requirements of the cylinder of the present invention, and has less impact on the return stroke, it is preferred to use a single-acting cylinder. In addition, the gas circuit and control signals of the double-acting cylinder are more complicated.

参照图4所示的气路原理图，第一气缸12和第二气缸5的无杆腔分别与换向阀14的两个工作口相通，换向阀14的进气口与气泵13相通。为了控制流入第一气缸12和第二气缸5的高压气体的流量和速度，还可以在第一气缸12和第二气缸5的无杆腔分别与换向阀14的两个工作口之间的气路上还设有单向节流阀15。换向阀14优选采用二位五通双电磁铁先导式换向阀。Referring to the schematic diagram of the air circuit shown in FIG. 4 , the rodless chambers of thefirst cylinder 12 and thesecond cylinder 5 communicate with the two working ports of thereversing valve 14 respectively, and the air inlet of the reversingvalve 14 communicates with theair pump 13 . In order to control the flow rate and the speed of the high-pressure gas flowing into thefirst cylinder 12 and thesecond cylinder 5, it is also possible to connect the rodless cavity between thefirst cylinder 12 and thesecond cylinder 5 and the two working ports of thereversing valve 14 respectively. A one-way throttle valve 15 is also provided on the gas path. The reversingvalve 14 is preferably a two-position five-way double electromagnet pilot-operated reversing valve.

应用图4实施例所对应的内衬纸卷筒装夹支架实施例进行内衬纸卷筒装夹的方法包括以下步骤：控制换向阀的切换方向来使第一气缸伸出活塞杆，推动芯轴向座体内腔的封闭端移动，并带动第二气缸收回活塞杆，这样就将夹紧块收回到座体内；再将内衬纸卷筒套在所述座体上，并控制所述换向阀的切换方向来使所述第二气缸伸出活塞杆，推动所述芯轴向所述座体内腔的开放端移动，并带动所述第一气缸收回活塞杆，这样就利用夹紧块顶紧了内衬纸卷筒的内腔。The method for clamping a lined paper roll using the embodiment of the lining paper roll clamping bracket corresponding to the embodiment in Figure 4 includes the following steps: controlling the switching direction of the reversing valve to make the first cylinder stretch out the piston rod, pushing The core shaft moves to the closed end of the inner cavity of the seat, and drives the second cylinder to retract the piston rod, so that the clamping block is retracted into the seat; then the lining paper roll is placed on the seat, and the The switching direction of the reversing valve causes the second cylinder to extend the piston rod, pushes the core shaft to move towards the open end of the seat inner cavity, and drives the first cylinder to retract the piston rod, thus utilizing clamping The blocks tighten the inner cavity of the lined paper roll.

现有的内衬纸卷筒装夹支架的夹紧块的调整空间较小，难以适应制造过程中所存在的内直径大小差异的各种内衬纸卷筒的安装夹紧，因此往往会出现难以夹紧或者装夹不上的问题，而本发明通过弹性滑块和气缸调整弹性结构的使用，显著提高了夹紧块的调整空间，使得内衬纸卷筒装夹支架能够适应制造过程中所存在的内直径大小差异的各种内衬纸卷筒的安装夹紧。另外，气缸调整弹性结构使得夹紧块的调整更为准确可靠，实现良好的夹紧效果。The adjustment space of the clamping block of the existing lining paper roll clamping bracket is small, and it is difficult to adapt to the installation and clamping of various lining paper rolls with different inner diameters in the manufacturing process, so it often occurs It is difficult to clamp or cannot be clamped, but the present invention significantly improves the adjustment space of the clamping block through the use of the elastic slider and the cylinder to adjust the elastic structure, so that the clamping bracket of the inner liner paper roll can be adapted to the manufacturing process. The installation and clamping of various inner lining paper rolls with different inner diameters. In addition, the elastic structure of the cylinder adjustment makes the adjustment of the clamping block more accurate and reliable, and achieves a good clamping effect.
