First of all, the film outlet thickness should be adjusted evenly.

Minor, the temperature is set to be accurate at each point, the temperature is not enough, the raw materials are not completely melted and the particles are easily generated, the heating is overheated, and the raw materials are dissimilated, which may cause the film surface to be broken.

Third, the cooling damper should be appropriate, the damper is too large to cause the film tube to be unstable, 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 take-up wheels is accurate, 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.

Five must, the winding table should be smoothed to the left and right, and the end of the winding can be leveled and compacted.

Some domestic manufacturers are limited to 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, the height is uneven, the belt is too thick, the length is too short, and it is used in the strapping machine, often the beak Corruption seriously affects the normal packaging and bundling procedures. On the other hand, if the belt is soft, the pulling force is strong, and the length is enough, it will not cause machine failure, and it will be handy, saving a lot of labor consumables cost.
