First, the film rolls are put into the uncoiler, and then the workers stick a splicing tape on the end of the moldy film roll, which can connect the front and back of each film roll and provide uninterrupted materials for the production line. At the same time, the uncoiler will also coat a layer of solvent on the surface of the film to prevent the film from sticking together during uncoiling. Moreover, this automatic tension regulator can ensure the machine to draw the film evenly and avoid wrinkling. Next, the machine applies hot melt adhesive to one side of the film. This hot flux is composed of several components, among which synthetic rubber gives it elasticity, anti-ultraviolet agent prevents it from drying and discoloring, antioxidant can prevent the adhesive tape from aging, synthetic resin makes it sticky, and dyes make the adhesive tape appear different colors. In order to prevent the hot flux from hardening, it needs to be put into a preheated storage box and kept at a high temperature of 200 degrees Celsius.

Secondly, the storage box pumps the glue into the glue applicator, and the worker removes the excess glue and starts to roll the film, at which time the film becomes sticky. There is a black cooling roller above the crumbs, which can cure the glue on the film immediately. Numerical control sensors are used to ensure that the adhesive is evenly applied. If there are any defects, the machine will send a signal to adjust the output parameters. Next, the rewinder rewinds the tape back to the reel. When the reel is completely wound, the blade will cut the tape at the bonding point. Then cut the tape1.5m wide into several sections with a row of slitters with sharp blades. Generally, the bandwidth of transportation adhesive is 48 mm, so each barrel of adhesive tape can be cut into 365,438+0 parts. They are all wrapped around the cardboard core and sealed with labels at the end of the tape.

Thirdly, the length of each roll of tape will be different according to the requirements of customers. When the machine ejects the finished tape rolls, they will enter the packaging area. But before these tapes are packed and shipped out, they still need to carry out quality inspection. The factory will take a sample from each batch for inspection. The self-inspection personnel will unfold the adhesive tape with the adhesive side facing upwards, then let the stainless steel ball roll in freely from the slope, and then measure the rolling distance of the ball on the adhesive tape. Only when the ball stops within a certain distance can it pass the inspection. Finally, the tested tape can be packaged and shipped to customers.
