Description

Foam double-sided adhesive close-fitting quick-freezing laminating machine

Technical field:

The utility model relates to the technical field of laminating machines, in particular to a foam double-sided adhesive closely laminating quick-freezing laminating machine.

Background technique:

Double-sided tape is a roll-shaped product that is coated with glue on both sides of a certain substrate for bonding between objects. In industrial applications, it is often necessary to cut the double-sided tape into the desired shape before using it. At present, foam double-sided adhesive products generally first bond the base material and the adhesive, and then use a punching die to punch out the desired shape. However, the existing bonding devices are all carried out at room temperature. After the surface adhesive products are pasted, they are transported to the punching device at room temperature for punching. Since the foam double-sided adhesive products will be sticky when they contact the surface of the die-cutting mold at room temperature, the foam double-sided adhesive products will adhere to the surface after punching. On the surface of the mold, the outer edge of the product is not smooth, which is prone to wire drawing and residual glue. The defective rate of the product is high, the work efficiency is low, and the cost is increased.

When working, the materials unwound by the two unwinding mechanisms are tightly pressed by the bonding roller device and then pass through The quick-freezing device is quick-frozen and then transported out. When passing through the quick-freezing device, the liquid nitrogen in the refrigeration container will transfer the low temperature to the frozen metal plate, and then the frozen metal plate will transfer the temperature to the bottom surface of the bonded product, so that the product will pass through the frozen metal plate. It can achieve the effect of rapid freezing. When the product shape is punched after laminating the quick-frozen double-sided adhesive product, due to the low temperature of the frozen double-sided adhesive product, the viscosity of the low-temperature double-sided adhesive decreases when it contacts the surface of the die-cutting mold, and it is not easy to adhere to it. The surface of the punching die is smooth, and the peripheral edge of the product is smooth, and it is not easy to produce wire drawing and residual glue, thereby reducing the defect rate of the product, reducing the cost, and improving work efficiency at the same time.
