Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubberizing equipment, in particular to a micro-porous polyurethane foam rubberizing equipment capable of switching between single-sided and double-sided rubberizing. BACKGROUND

[0002] Foam is a material foamed from plastic particles. Foam has a series of characteristics such as elasticity, light weight, free bending, and reliable performance. Double-sided adhesive tape can be made by attaching foam to the surface of the double-sided adhesive tape, which has good sound insulation, shock absorption, waterproofness, and sealing performance. When foam adhesive is being made, the top roller is used to attach the adhesive tape to the outside of the foam adhesive, so that the foam adhesive tape can be made.

[0003] For example, the application number CN202110222924.6 relates to a foam rubberizing mechanism, which includes a rack, a feeding device, and a rubberizing device. The feeding device includes a unwinding assembly and a winding assembly arranged on the rack. The unwinding assembly and the winding assembly are arranged at intervals, so that the two ends of the foam are respectively gathered in the unwinding assembly and the winding assembly to convey the foam. The rubberizing device includes a rubberizing assembly and a pressing assembly arranged on the rack. The pressing assembly is located between the rubberizing assembly and the winding assembly. The rubberizing assembly is used to install the rubberizing component. The pressing assembly presses the part of the rubberizing component away from the rubberizing assembly to the foam to be tightly attached. The present application realizes automatic rubberizing of foam through mechanical structure, improves production efficiency, and can improve the consistency of the rubberized foam.

This leads to poor practicability of the rubberizing equipment. Moreover, the existing micro-porous polyurethane foam rubberizing equipment cannot simultaneously rubberize foams of different widths. The rubberizing machine can only rubberize one kind of foam at a time, which leads to low production efficiency of the rubberizing machine. SUMMARY
