Plastic thin film preparing and coiling method

Abstract

The invention relates to a plastic thin film preparing and coiling method, in particular to a plastic thin film preparing and coiling device. The device comprises a base, a feeding mechanism for conveying a plastic thin film, an intermittent rotation mechanism, four internal supporting mechanisms for internally supporting and clamping a paper tube, a press rolling mechanism for pressing the plastic thin film down, a coiling driving mechanism for driving the paper tube ro rotate to coil the thin film, and a film cutting mechanism used for cutting a plastic thin film belt off. The device involved in the method can be suitable for coiling the plastic thin film on the paper tubes with different internal diameters, continuous coiling operation can be completed at a batch, unnecessary repetitiveoperation is avoided, and the plastic thin film coiling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plastic film processing, and specifically proposes a method for preparing and winding a plastic film. Background technique [0002] Plastic film refers to films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging, and as a coating layer. Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging , quick-frozen food packaging, cooking food packaging, fast food packaging, etc., these products have brought great convenience to people's lives. [0003] In the production process, the plastic film generally needs to be divided into plastic film strips with a certain width and standard by slitting. Finally, the p...

Problems solved by technology

[0003] In the production process, the plastic film generally needs to be divided into plastic film strips with a certain width and standard by slitting. Finally, the plastic film strip needs to be rolled up and then packaged. The plastic film is usually wrapped on a paper tube before packaging. , the rolls used to set the paper tube in the existing plastic film winding equipment are basically non-adjustable, but the actual length and inner diameter of the paper tube used for winding are not the same, so this type of winding equipment It is not suitable for a variety of paper tubes of different sizes. In addition, the existing winding equipment has a relatively simple structure, and generally can only perform simple winding operations, and cannot perform continuous winding operations.
