Film pressing device for plastic bag molding production and processing

Abstract

The invention relates to the field of film pressing devices, in particular to a film pressing device for plastic bag molding production and processing. The film pressing device comprises a placement mechanism, an expansion column mechanism, a protection mechanism, a tensioning mechanism and a printing mechanism. A supporting body can be adjusted in a self-adaptive mode through the arrangement of the placement mechanism, and noise to the ground generated during operation of the supporting body can be reduced; film roll materials with different inner diameters can be conveniently connected in asleeved mode through the arrangement of the expansion column mechanism, and the use flexibility of the supporting body is improved; a rotating part in the supporting body can be shielded through the arrangement of the protection mechanism, external foreign matter is prevented from falling into the main body, so that the use safety of the main body is guaranteed; the roll material can be tensionedthrough the arrangement of the tensioning mechanism, loosening of the film during winding is avoided; and the film can be conveniently printed while being wound and pressed through the arrangement ofthe printing mechanism, and therefore the use experience of the main body is improved.

Description

technical field [0001] The invention relates to the field of film pressing devices, in particular to a film pressing device for plastic bag molding production and processing. Background technique [0002] Plastic bag is a bag made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. It is an indispensable item in people's daily life and is often used to hold other items. It is widely used because of its advantages of low cost, extremely light weight, large capacity and easy storage, but its production and use are banned in some countries and regions due to the disadvantages of extremely long degradation cycle and difficult disposal of plastic bags. [0003] Plastic bags need to use a special film pressing device during the production process. However, most of the traditional devices expose the rotating parts. This design is easy to get the operator's hair involved, resulting in major machine injuries, and Most of the tr...

It is widely used because of its low cost, extremely light weight, large capacity, and easy storage, but it is banned from production and use in some countries and regions due to the shortcomings of extremely long degradation cycle and difficult disposal of plastic bags.

[0003] Plastic bags need to use a special film pressing device during the production process. However, most of the traditional devices expose the rotating parts. This design is easy to entangle the operator's hair, resulting in major machine injuries, and Most of the traditional film pressing devices are mechanisms without printed logos, which increases the cost of separate printing in the later stage
