Correct choice of high quality end band and tear tape

With the exception of the use of raw materials, the end of the belt and the tearing tape, the machine used and the production process are almost the same. All are heated extrusion, blown film cooling, slitting cutting, heating extension, using the ratio of the front and rear extraction machine speed to achieve the best state of tension, and finally by the winding machine, the tearing tape or the ending tape is set to the weight Take it down. The process is not very complicated, but it is not easy to produce high-quality products. As the saying goes: If a worker wants to do good, he must first sharpen his tools. If the machinery and equipment are old and the production technology is not in place, we would like to produce products with excellent quality and satisfactory customers. How to master production tips, and now share many years of experience with the industry.

The "Five Essentials" Principle of Production and Processing

First and foremost, the thickness of the membrane head should be evenly adjusted

Minor, each point set the temperature to be accurate, the temperature is not enough, the raw materials can not be completely melted and easy to produce particles, heating and overheating, raw materials will be alienated, all may cause film surface hole.

Third, the cooling throttle should be appropriate. If the damper is opened too large, it will cause unstable diaphragm oscillation. The damper is too small, the cooling power is insufficient, and the film surface is prone to wrinkles.

Fourth, before and after taking the speed of the wheel to be accurate, the speed ratio is too low, the belt pull is not strong, the speed ratio is too high, the extension ratio is not enough, so the speed ratio must be accurate.

Fifth, the winding table must swing smoothly from left to right, and the end of coiling can be flat and dense.

Some domestic companies are limited to shortage of funds because they are short of funds, old machinery and equipment, and the products they produce are high in weight and low in tension. Their appearance varies in size, unevenness, and the straps are too thick and the length is too short. They are used in strapping machines and often put the beak Dirty, seriously affect the normal package bundling operation procedures. Conversely, if the straps are soft, strong in tension, and long enough to use, they will not cause problems with the machine and are handy. This will save a lot of labor costs.

Comprehensive assessment, careful purchase

The meticulous customer does not first consider the purchase price as the sole consideration for the price per kilogram. The quality of the belt is better than the length of the grammage, and a comprehensive assessment of the smoothness of the operation is used before deciding which supplier to purchase. Taicang and Xinyi have always been aiming to produce low-weight, high-tension, low-quality products with the same quality as the market, gradually expand the market, and expect to be accepted by the broad masses of customers.

Some manufacturers to reduce costs, doped with recycled materials or non-raw materials to make the end of the band, although the cost is reduced a lot, but the finished product is easy to break and heavy weight, the same one kilogram of the tape, less 3,400 meters The length, really counted, is not cheaper but more expensive. Smart users should have the right choice under careful consideration.

End band

From the appearance of the end of the roll into a cylindrical column, two trimming edge formation, winding lines clear and dense, the surface smooth and straight, two no size, high flexibility of the tape, hand-pinch texture is good, both sides of the belt folded, symmetrical and uniform, will not Like hand-wound tape, this is a good tape. On the contrary, if the two ends are not even, there may be joints or hems.

Ribbons with joints, because the joints are in agglomerates, can cause the conveyor belt to be blocked and broken during use, and can cause serious damage to the beak, gear, or blade of the knotter. The inferior 50# tape is more troublesome in the automatic strapping machine assembly line. It is often necessary to shut down and re-thread the tape, seriously affecting the normal operation of the entire production line.

Folding is not good, and the loose-wound tape often slips off the periphery of the barrel itself and wraps around the bottom of the barrel during use, resulting in the belt not being pulled or being pulled off. This condition will lead to bending and deformation of the tape guide, and the strapping machine cannot be used normally. Poorly folded straps can easily cause the blade to not completely cut the strap, resulting in dragging. The use of a long time will cause damage to the machine, and the curl will be smooth, and the edges of the hem will be balanced symmetrically. The static electricity will naturally attach to the column and will not fall on the ground. The use of natural smoothness and good use is very good.

Tear tape

Tear tapes are used for manual tying, as long as they are low in weight, strong in tension, long enough in length, uniform in width, and soft to the touch. They are good tapes. Tear tape can be divided into two types of flat and foamed tapes. The flat belt, as the name implies, means that the belt itself has no lines and is smooth as a mirror. The so-called foaming and tearing belts are lines on the surface of the tape, and the expanded and rolled up tapering shape is named as a foamed tearing tape.

Flat tear tapes are generally produced by domestic manufacturers, but the tearing and tearing belts are only produced by some foreign companies that have introduced technology from Japan and Taiwan because of their high technological composition. Teardrop tearing tapes are used in advanced countries and are widely used by customers because of its good softness, good hand feeling and strong pulling force. In addition, the characteristics of low weight make the cost of consumables significantly lower, and it is convinced that in the near future, the domestic market will also flourish.

The reason that the reason why the foamed tear tape can be light and strong is that the pattern on the tape is the same as the reinforcing steel in the beam column, and it reinforces the strength and strength of the reinforcing tape itself.

In China, general manufacturers are also accustomed to using recycled materials made of tear tape, that the packaging supplies, use it is lost, can save on the province. It is thought that buying remanufactured goods is cheaper than new finished goods. In actual fact, the quality of the recycling system is heavy, the number of meters is short, and the pulling force is low, while the new material system is light in quality, long in meters, and strong in tension. The use of meters as the cost of the cost, cheaper than the re-product, used in the bundle should calculate the cost of meters, should not calculate the cost of kilograms. As long as we are guided by the concept, pure new material tear tape will gradually replace the recycling of tear tape.
