Thermoplastic film winding device for quantified cutting

Abstract

The invention relates to the field of thermoplastic film processing equipment, in particular to a thermoplastic film winding device for quantified cutting. The device includes a support, a motor is installed on the left side of the support, and the output shaft of the motor is provided with a material winding disk for winding thermoplastic film, wherein a support rod is fixed to the right side of the support, and a transitional roller is rotatably matched with the support rod; the thermoplastic film bypasses the transitional roller and enters from the bottom end surface of the material winding disk; the top end surface of the transitional roller is higher than the top end surface of the material winding disk; a supporting base is fixed to the support and fixedly provided with a cutter, and the cutter is located between the material winding disk and the transitional roller. According to the thermoplastic film winding device for quantified cutting, when the thermoplastic film on the material winding disk is wound to a certain thickness, the thermoplastic film between the transitional roller and the material winding disk is in contact with the cutter, and cut off by the cutter; since the edge cutting position of the cutter remains unchanged every time, the amount of the thermoplastic film which is wound on the material winding disk is equal every time, quantified cutting of the thermoplastic film is achieved without judgement or weighing in a manual mode, processes are reduced, and the operation is much simpler and more convenient.

Description

technical field [0001] The invention relates to the field of thermoplastic film processing equipment, in particular to a thermoplastic film winding device for quantitative cutting. Background technique [0002] Thermoplastic film is a common packaging product in daily life. Thermoplastic film has high strength and good durability. Thermoplastic film shrinks when preheated to cover the product, and is often used for shrink packaging of irregular products, cosmetics, ceramic tiles and the electronics industry, etc. 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. [0003] When winding thermoplastic film into rolls, in order to facilitate transportation and sales, the quantity of each roll of thermoplastic film is fixed to ensure that the price is equal...

AI Technical Summary

Problems solved by technology

When winding the thermoplastic film on the reel, it is necessary to ensure that the number of thermoplastic films in each roll is basically the same. Usually, it is judged by experience or measured after winding. The operation is troublesome and the error is large; When the quantity of the film is unqualified, it cannot be rewound and can not be remedied; when the thermoplastic film is wound and cut off, the thermoplastic film on the unwound side is easy to retract, so that the next winding Unable to find the starting edge of the thermoplastic film
