The invention relates to the technical field of thermoplastic film production machining equipment, in particular to a thermoplastic film winding mechanism. The thermoplastic film winding mechanism comprises a bracket, and a motor is installed on the bracket; a receiving disc is installed on an output shaft of the motor, a flattening abutting block is arranged below the receiving disc, and the lower end of the flattening abutting block is connected with a compression spring; the top end of the flattening abutting block is provided with an arc-shaped groove which is matched with the outer edge of the receiving disc and used for flattening a thermoplastic film; the arc-shaped surface of the arc-shaped groove is provided with a soft film; and the lower end of the compression spring is providedwith an airbag capable of being pressed by the compression spring, the air exhaust end of the airbag communicates with an air channel in the flattening abutting block through a hose, and the air channel communicates with the upper portion of the soft film. The thermoplastic film winding mechanism further comprises a cylinder body, the cylinder body is provided with a one-way air inlet valve and aone-way air outlet valve, and the one-way air outlet valve communicates with the air inlet end of the airbag. The problem that a thermoplastic film is prone to being bonded with a soft film due to the fact that an airbag cannot continuously supply air is solved.
Description
technical field [0001] The invention belongs to the field of thermoplastic film production and processing equipment, and in particular relates to a thermoplastic film coiling mechanism. Background technique [0002] Thermoplastic film is used in the sale and transportation of various products, and the main function of thermoplastic film is to stabilize, cover and protect the product. Thermoplastic film has high puncture resistance, good shrinkage and certain shrinkage stress. Thermoplastic film is widely used. During the shrinking process of thermoplastic film, thermoplastic film will not produce holes and is easy to use. [0003] The production process of thermoplastic film includes formulation, kneading, granulation, thick film extrusion, air cooling, heating in hot water bath with boiling water, transverse blowing of shaping cylinder, defoaming of sandwich roller and winding into thermoplastic film. In the process of winding into a thermoplastic film, the tension of the...
