Manufacturing method of film on concrete surface

Abstract

The invention discloses a method for manufacturing a film applied on the surface of concrete, which includes the following steps: firstly, one end of the film is wound on a take-up roller, a spring is used to make the pressure wheel compress the film on the take-up roller, the motor is turned on, and the motor drives The driven shaft rotates, so that the take-up roller rotates, and the film is wound on the take-up roller evenly. When the take-up roller needs to be replaced, take off the positioning rod on the drive roller, and quickly pull the take-up roller from the drive roller. Take it off, put a new winding roller on the driving roller, reinstall the positioning rod, fix the winding roller on the driving roller, complete the quick replacement of the winding roller, and continue to wind the film. The invention can quickly replace the winding roller and improve the processing efficiency of the film. Meanwhile, during the film winding process, the film can be wound on the winding roller smoothly to avoid wrinkling.

Description

technical field [0001] The invention relates to a film processing tool, in particular to a method for manufacturing a film applied on the surface of concrete. Background technique [0002] After the concrete is poured and shaped, it needs to maintain a certain humidity to facilitate the formation of crystals inside the concrete. The usual method is to sprinkle water and cover the film. Most of the plastic films are usually used. During the processing of the plastic film, the material is first melted, and then passed through Forming, cooling, and finally the film is rolled up by the receiving mechanism. After the plastic film is processed, it is usually rolled into a barrel, and then the finished plastic film is transported to the warehouse for centralized storage. At present, most of the cooling rollers are used to wind up the cooled plastic film for storage. After the plastic film on the winding roller is wound up, another winding roller needs to be changed, and then the pl...

Problems solved by technology

At present, most of the cooling rollers are used to wind up the cooled plastic film for storage. After the plastic film on the winding roller is wound up, another winding roller needs to be changed, and then the plastic film continues to be rolled up. For rewinding, the existing loading and unloading rewinding rollers are more cumbersome, and the loading and unloading time is longer, which affects the processing efficiency of the plastic film.
