Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag production, in particular to a plastic bag production raw material cutting device. Background Art

[0002] Plastic packaging bags are made of plastic as raw material and are used to produce various daily necessities. They are widely used in daily life and industrial production, but this temporary convenience brings long-term harm. Commonly used plastic packaging bags are mostly made of polyethylene film, which is non-toxic, so it can be used to hold food. There is also a film made of polyvinyl chloride, which is also non-toxic, but the additives added according to the purpose of the film are often harmful to the human body and have certain toxicity. Therefore, this type of film and the plastic bags made of this film are not suitable for holding food. In the production process of plastic bags, it is usually necessary to cut the raw materials to facilitate subsequent production operations, but the cutting devices commonly used on the market usually have relatively simple functions and poor flexibility, which is not convenient for processing materials of different specifications.

[0003] For example, a plastic bag production raw material cutting device disclosed in the authorization announcement number CN204777796U includes a base and a transport device, wherein brackets are respectively installed at the left and right ends of the base, a fixing plate is provided on the top of the bracket, and cylinder 1 and cylinder 2 are respectively installed on the fixing plate, a pressure block is installed on the top of cylinder 1, a cutter is installed on the top of cylinder 2, a baffle is installed between the cutter and the top of cylinder 2, a cutting table is provided at the corresponding position of the base and the cutter, and a baffle is provided on the left end of the cutting table. The utility model of a plastic bag production raw material cutting device can prevent damage caused in the production of plastic bags by providing a pressure block at the bottom of the conveying device, thereby improving production efficiency, and at the same time, a baffle is installed between the cutter and the top of the cylinder, which can not only facilitate the replacement and installation of the cutter, but also cooperate with the baffle to prevent damage caused to the plastic bag during the production process, thereby increasing the safety of cutting. However, the utility model lacks flexible space adjustment function and convenient material fixing measures, which makes it inconvenient for operators to flexibly control the cutter head and position and fix the raw materials according to different cutting requirements. For this reason, we propose a plastic bag production raw material cutting device, which solves the problems of flexible control of the cutter head and positioning and fixing of the raw materials of the device, improves the use flexibility of the device, expands the application scope of the device, and thus improves the processing quality.
