KTC80型切丝机减少夹刀现象的方法The Method of Reducing the Phenomenon of Knife Clamping in KTC80 Shred Cutting Machine

技术领域technical field

本发明属于烟草加工设备技术领域，具体涉及一种通过设备结构优化以减少KTC80型切丝机发生夹刀现象的方法。The invention belongs to the technical field of tobacco processing equipment, and in particular relates to a method for reducing the phenomenon of knife clamping in a KTC80 type shredding machine through equipment structure optimization.

背景技术Background technique

KTC80型切丝机目前在国内烟草行业应用广泛，随着配件国产化率的增加，KTC80型切丝机导丝条在使用过程中经常出现排丝不畅、烟丝粘连在导丝条上等问题，造成切丝后烟丝宽窄不均、造碎，俗称“夹刀现象”。切丝宽度不均匀可由多种原因造成，在对设备、来料检查排除了其它因素后，夹刀现象成为影响烟丝宽窄不均的主要原因。夹刀现象会直接影响到八边形刀辊体重量的分布状态，引起动平衡偏差、噪音大，从而影响切丝宽度；还会造成刀片伸出阻力增大，进而增加了推刀半螺母、进刀轴的磨损，降低了零件的配合精度和使用寿命。如何克服就成为现有技术中亟待解决的问题。KTC80 shredding machine is widely used in the domestic tobacco industry at present. With the increase of the localization rate of accessories, problems such as poor shredder discharge and sticking of tobacco on the wire guide bar of KTC80 shredding machine often occur during use. , causing the shredded tobacco to be uneven in width and broken, commonly known as the "clamping knife phenomenon". The uneven cutting width can be caused by many reasons. After checking the equipment and incoming materials and excluding other factors, the phenomenon of knife clamping becomes the main reason affecting the uneven width of shredded tobacco. The knife clamping phenomenon will directly affect the weight distribution of the octagonal knife roller body, causing dynamic balance deviation and high noise, which will affect the cutting width; it will also increase the resistance of the blade extension, which will increase the push knife half nut, The wear of the feed shaft reduces the matching accuracy and service life of the parts. How to overcome just becomes the problem to be solved urgently in the prior art.

具体实施方式Detailed ways

下面结合附图和实施例对本发明作进一步地详细说明，但附图和实施例并不是对本发明技术方案的限定，所有基于本发明教导所作的变化，均属于本发明的保护范围。The present invention will be described in further detail below in conjunction with the accompanying drawings and examples, but the accompanying drawings and examples do not limit the technical solution of the present invention, and all changes made based on the teachings of the present invention belong to the protection scope of the present invention.

实施例1Example 1

现有导丝条结构如图1所示，经深入研究后可以发现：导丝条抛料槽(1)半径为1mm，与容积槽(2)的连接过程中呈锐角过渡。在使用时，烟丝在经过半径为1mm的抛料槽(1)时由于圆弧半径不够，瞬间切出的烟丝抛出速度降低，同时又受到抛料槽和容积槽过渡锐角的影响，烟丝在容积槽上滑落的速度降低，造成烟丝落料不畅，在容积槽内容易产生堆积，造成夹刀现象。The structure of the existing guide wire is shown in Figure 1. After in-depth research, it can be found that the radius of the guide wire throwing groove (1) is 1mm, and the connection process with the volume groove (2) is an acute angle transition. When in use, when the shredded tobacco passes through the throwing chute (1) with a radius of 1 mm, the throwing speed of the shredded tobacco cut out instantly decreases due to the insufficient radius of the arc. The speed of sliding down on the volume tank is reduced, resulting in poor blanking of shredded tobacco, and easy accumulation in the volume tank, resulting in the phenomenon of knife clamping.

通过分析，提出对导丝条的改进方法：Through the analysis, the improvement method of the guide wire is proposed:

(1)大量试验证明，导丝条抛料槽(1)的圆弧半径尺寸对夹刀现象的影响很大，抛料槽的圆弧半径大小是造成夹刀现象的因素之一。抛料槽(1)的圆弧半径设计和加工很重要，圆弧半径太大，烟丝通过抛料槽(1)卷曲后被抛到容积槽(2)的中上部，冲击大，产生噪音和振动；抛料槽(1)圆弧半径过小，与容积槽(2)的结合处形成向上翘起的尖角，阻碍烟丝的快速滑落，夹刀现象频繁出现，增加了切削阻力。(1) A large number of tests have proved that the size of the arc radius of the guide wire throwing trough (1) has a great influence on the phenomenon of knife clamping, and the size of the arc radius of the throwing trough is one of the factors causing the phenomenon of knife clamping. The arc radius design and processing of the throwing chute (1) is very important. If the arc radius is too large, the shredded tobacco will be curled through the throwing chute (1) and thrown to the middle and upper part of the volume trough (2), which will have a large impact and generate noise and Vibration; the arc radius of the throwing trough (1) is too small, and the junction with the volume trough (2) forms an upwardly tilted sharp angle, which hinders the rapid sliding of shredded tobacco, and frequent knife clamping phenomenon increases cutting resistance.

如图2所示，将导丝条抛料槽(1)的圆弧半径改进为2mm，抛料槽与容积槽的结合处改进为R0.5mm的过渡圆弧(3)，从而有效改善圆弧面少量积垢后造成曲面弧度不够的问题，减少容积槽内的夹丝，降低夹刀现象的发生。As shown in Figure 2, the arc radius of the guide wire throwing groove (1) is improved to 2mm, and the junction of the throwing groove and the volume groove is improved to a transition arc (3) of R0.5mm, thereby effectively improving the circular arc radius. A small amount of fouling on the curved surface will cause the problem of insufficient curvature of the curved surface, reduce the wire clamping in the volume tank, and reduce the occurrence of knife clamping.

(2)在导丝条的使用过程中发现，切刀的伸出量均在5.5mm以上，切刀伸出量过长，容易在切削过程中造成刀片颤动，使刀片的刚性降低，在切割物料(压实的烟饼)对切刀的反作用力下，切刀与导丝条的贴合面出现微量间隙，碎烟末等细小杂质进入，造成刀片与基座积垢，抛料槽(1)积垢后，排丝不顺畅，最终造成容积槽(2)粘连烟丝，出现夹刀现象。通过多年对切丝质量观察，切刀在切丝过程中，当切刀的伸出量在4～5mm时切丝质量最稳定，为此将导丝条高度(4)改进为28.3mm，在压刀板对刀片压紧力不变的前提下，通过增加导丝条的高度，使压刀板、切刀、导丝条贴合更加紧密，同时缩短刀片的伸出量，降低夹刀现象的发生。(2) During the use of the guide wire, it was found that the extension of the cutter is above 5.5mm. If the extension of the cutter is too long, it is easy to cause the blade to vibrate during the cutting process, which reduces the rigidity of the blade. Under the reaction force of the material (compacted tobacco cake) on the cutter, a slight gap appears on the bonding surface of the cutter and the guide wire, and small impurities such as crushed tobacco enter, resulting in fouling of the blade and the base, and the throwing trough ( 1) After fouling, the wire discharge is not smooth, which eventually causes the volume tank (2) to stick to the shredded tobacco, and the phenomenon of knife clamping occurs. Through years of observation of the shredded quality, the shredded quality is the most stable when the cutter protrudes 4-5mm during the shredded process. Therefore, the height of the guide wire (4) is improved to 28.3mm. Under the premise that the pressing force of the knife plate on the blade remains unchanged, by increasing the height of the wire guide, the pressure plate, the cutter, and the guide wire can fit together more closely, and at the same time shorten the extension of the blade to reduce the phenomenon of knife clamping happened.
