Single-side glue spraying device for PE film and using method of single-side glue spraying device

Abstract

The invention discloses a single-face glue spraying device for a PE film. The single-face glue spraying device comprises a device base, a tensioning roller is installed on the left side of the devicebase, the tensioning roller is installed above the device base through a tensioning support, the tensioning support comprises a tensioning screw rod, the tensioning screw rod is installed on one sideof the tensioning support, a roller seat is installed at the upper end of the tensioning screw rod, a tensioning roller is installed at the upper end of the roller seat, the roller seat is slidably connected with the tensioning support, a leveling device is installed on the right side of the tensioning roller, a spraying device is installed on the right side of the leveling roller, a brushing device is installed on the right side of the spraying device, the brushing device comprises a brushing roller, and a smearing device is installed on the right side of the brushing roller and comprises a lower smearing supporting plate and an upper smearing supporting plate, glue waste is reduced, smearing is more uniform, meanwhile, part of glue on the PE film can be recycled, meanwhile, the gluing thickness of the PE film is controlled, the cost is saved, and meanwhile the adhesive force of the glue is increased.

Description

technical field [0001] The invention relates to the technical field of PE film manufacture, in particular to a single-sided glue spraying device for PE films and a method for using the same. Background technique [0002] In the product structure, the PE film is placed under the surface paper, mainly to provide decorative patterns and cover functions to prevent the bottom glue from seeping out. This layer requires paper with good hiding power, impregnation and printing properties. PE film requires a smooth surface, good absorption and adaptability, uniform color tone for background color, and bright color for color. In the production process of PE film, it is necessary to set dipping glue on one side of PE film, so that it can be pasted more conveniently during use. However, there are still few devices for single-sided glue coating at this stage, which cannot meet the current use needs. Some devices use a brushing tube for brushing. Brushing with a brushing tube will cause ...

Problems solved by technology

In the production process of PE film, it is necessary to set dipping glue on one side of PE film, so that it can be pasted more conveniently during use. However, there are still few devices for single-sided glue coating at this stage, which cannot meet the current use needs. Some devices use a brushing tube for brushing. Brushing with a brushing tube will cause uneven brushing, and it is difficult to collect the brushing glue, which is wasteful. It will cause problems such as solidification of the brushing glue for a long time. It will cause the adhesive force of the PE film to be weak, which will cause the edge or bag to be removed in the later stage, which will affect the appearance of the later stage. It is necessary to design a device that can increase the adhesive force of the brushing glue and can recycle the glue at the same time.
