Plastic film cutting and conveying method

Abstract

The invention provides a plastic film cutting and conveying device. The plastic film cutting and conveying device comprises a machine frame, a roller assembly, a cutting bade and a plastic film to bemachined. The roller assembly comprises a conveying roller assembly and a steering roller assembly, wherein the conveying roller assembly is used for conveying the plastic film and vertically conveying the plastic film to the bottom of the machine frame; and the steering roller assembly is installed below the conveying roller assembly and used for changing the plastic film from vertical displacement to horizontal displacement. The cutting blade is arranged between the conveying roller assembly and the steering roller assembly, and the cutting edge of the cutting blade cuts the plastic film inthe moving direction of the plastic film. A conveying belt corresponding to the cut plastic film is arranged below the steering roller assembly. The conveying roller assembly guarantees that the plastic film cannot be bent or wrinkled in the conveying process, the cutting blade below the conveying roller assembly carries out cutting work easily, the cut plastic film is changed from the vertical state to the horizontal state through the steering roller assembly and brought out of the device, and further packaging and using are facilitated.

Description

[0001] This application is a divisional application of a patent with an application number of 2016104963981 and an application date of June 30, 2016, entitled "A Plastic Film Cutting and Conveying Device". technical field [0002] The invention relates to the technical field of packaging material preparation, in particular to a plastic film cutting and conveying device. Background technique [0003] In recent years, plastic products have been widely used, especially film-type plastic bags, plastic woven bags and other products. These plastic products have brought us a convenient life. During the production process, we need to cut the plastic film for our convenience. In the prior art, manual operation is usually required, so that the plastic film is prone to problems such as different lengths and labor costs. For example, the patent number is: 200920108311.4; although this patent can achieve automatic cutting to a certain extent, there are still unavoidable problems, such a...

AI Technical Summary

Problems solved by technology

In the prior art, manual operations are usually required, which makes the plastic film prone to problems such as different lengths and labor costs.

For example, the patent number is: 200920108311.4; although this patent can achieve automatic cutting to a certain extent, there are still unavoidable problems, such as complex structure, difficult maintenance, low degree of automation, and the need to adjust the transmission motor and cutting motor separately when adjusting the cutting length , making the adjustment more difficult, because the plastic woven bag is relatively soft, it is easy to have problems such as incomplete cutting when cutting

[0004] Another example is the patent No. 201410555558.6: the patent transmits the plastic film horizontally and cuts it by setting up the transmission component and the conveyor belt, but the plastic film is electrostatically adsorbed on the conveyor belt during transmission, and the plastic film is easily wrinkled or cut during the cutting process. The defect of uneven knife edge is not conducive to the processing and production of subsequent extrusion
