In addition to the use of different raw materials, the machine and production process of the end tape and tear tape are almost the same. All are heating extruding, film blowing cooling, slitting cutting, heating extension, using the ratio of the speed of the front and back take-up machine to achieve the best state of the pulling force, and finally passing the take-up machine to bring the tear tape or end tape to the set weight Take off. The process is not very complicated, but it is not easy to produce high-quality products. As the saying goes: Workers must first sharpen their tools if they want to do their best. If the machinery and equipment are old and the production technology is not in place, it is a dream to produce products of good quality and customer satisfaction. How to master the production tips, now share the years of experience gained with the industry.
"Five Essentials" Principles of Production and Processing
First and foremost, the thickness of the membrane outlet should be adjusted evenly
Secondly, the temperature must be set accurately at each point. If the temperature is not enough, the raw material will not melt completely, which will easily produce particles. If the material is heated and overheated, the raw material will dissimilate, which may cause holes in the film surface.
Thirdly, the cooling damper should be appropriate. If the damper is too open, it will cause unstable shaking of the membrane tube. If the damper is too small, the cooling force is not enough, and the membrane surface is prone to wrinkles.
Fourth, the speed ratio of the front and rear pick-up wheels must be precise. The speed ratio is too low, the belt tension is not strong, the speed ratio is too high, and the extension ratio is not enough, so the speed ratio is accurate.
Fifthly, the winding table should swing smoothly from side to side, and the end band of winding can be smooth and dense.
Some domestic companies are limited by the shortage of funds, because they are simple, the equipment is old, the products produced are high in weight and low in tension, the appearance is different in size, uneven, the strap is too thick, the length is too short, it is often used in strapping machines, and the beak is often used Broken, seriously affecting the normal packaging and strapping procedures. On the contrary, if the strap is soft, strong in tension, and long enough, it will not cause machine failures when used, and it is handy and saves a lot of labor and consumable costs.
Comprehensive evaluation, careful purchase
Careful customers do not first consider the price per kilogram as the sole consideration for purchase orders. The quality of the belt, the ratio of the length of the same gram weight, and the comprehensive evaluation of the smoothness of the operation use, before deciding which to purchase. Taicang and Xin have always been producing low-gram weight, high-tension, low-price products of the same quality as the market positioning, gradually expanding the market, and expecting to be accepted by the broad customer base. In order to reduce the cost, some manufacturers use doped recycled materials or non-drawing materials to make the end tape. Although the cost is reduced a lot, the finished product is easy to break and weighs a lot. The same one kilogram of the tape is less than 3 or 400 meters. The length is really calculated, the cost is not cheap but more expensive. Smart users should have the right choice after careful consideration.
End zone
From the end of the appearance, the belt is rolled into a cylindrical shape, the edges of the two ends are flat, the winding pattern is clear and dense, the surface is smooth and straight, the two ends are not large, the strap is high in flexibility, and the texture of the hand is good. Wrapped together like a handmade band, this is a good band. On the contrary, if the two ends are not flat, there may be a phenomenon that the joint or the folding edge is not good. The jointed belt, because the joint part is agglomerated, will cause the conveyor belt to be blocked and broken during use. Over time, it will seriously damage the bird's beak, gear or blade of the knotting machine. The inferior 50 # tape has caused more troubles on the automatic strapping machine assembly line. It often needs to stop and re-thread the tape, which seriously affects the normal operation of the entire production line.
Badly folded, loosely curled straps, during strapping, often fall off the periphery of the barrel and wrap around the bottom, causing the strap to not pull or break. Such a situation will cause the guide bar to bend and deform, and the strapping machine may not be used normally. A tape with poor hem is likely to cause the blade to fail to cut the tape completely, resulting in dragging. Long-term use will cause damage to the machine, and the curled and smooth, symmetrical tapes at both ends of the hem are inherently static. It naturally adheres to the column and will not be scattered on the ground. The use of natural smooth and smooth, very easy to use.
Tear zone
The tear tape is used for manual binding, as long as it has a low weight, strong pulling force, sufficient length, uniform width, and good softness, it is a good strap. The tear tape can be divided into two kinds of flat and foam tapes in appearance. The flat strap, as the name suggests, is that the strap itself has no texture and is as smooth as a mirror. The so-called foam tearing tape means that the surface of the belt has a texture, which is stretched and wound to be bulky, so it is called foam tearing tape. Domestic flat tearing tapes are generally produced by domestic manufacturers, but foaming tearing tapes are only produced by the introduction of technologies from Japan and Taiwan because of the high technical composition. In advanced countries, foam tearing tapes are widely used by customers. The reason is that it has good softness, good hand feeling and strong pulling force. In addition, the low-gram weight feature has significantly reduced the cost of consumables. I am convinced that the domestic market will also flourish in the near future.
The reason why the foam tearing tape can be light in weight and strong in tension is that the lines on the belt are like the reinforcement in the beam and column, which strengthens and strengthens the toughness and strength of the belt itself. In China, general manufacturers are also accustomed to using the tear tape made of recycled materials, thinking that the packaging consumables are thrown away after use, which can save. I think buying recycled products is cheaper and more cost-effective than finished products made from new materials. In fact, the quality of recycled materials is heavy, the number of meters is short, and the pulling force is low, while the quality of the new material is light, the number of meters is long, and the pulling force is strong. The cost of using rice as a cost is cheaper than remanufactured products. The cost of tying should be calculated in meters, not in kilograms. As long as everyone corrects the concept, the new tear zone will gradually replace the recycled tear zone.
