A flame retardant fireproof high temperature resistant polyethylene film laying device

Abstract

The invention discloses a flame retardant, fireproof and high temperature resistant polyethylene film laying device. The flame retardant, fireproof and high temperature resistant polyethylene film laying device comprises a first supporting frame and further comprises supporting plates placed at the two ends of the first supporting frame and used for supporting a polyethylene film; locating framesare movably arranged at the middle parts of the two supporting plates; uprights are arranged at the middle parts of two third supporting frames; a third roll wheel used for flattening the film is movably arranged between the two uprights; and the end parts of the two third supporting frames are fixedly connected with the two ends of a holding handle. According to the flame retardant, fireproof andhigh temperature resistant polyethylene film laying device, a polyethylene film rolling wheel can be supported by using a locating frame; as the locating frame can rotate, the polyethylene film rolling wheel on the locating frame rotates during pushing the first supporting frame so as to unwind the polyethylene film so as to lay the polyethylene film on the ground; and by enabling the third rollwheel to press the polyethylene film, the polyethylene film can generate a tangential force to the polyethylene film rolling wheel to pull the polyethylene film rolling wheel to rotate so as to realize an automatic unwinding function.

Description

technical field [0001] The invention relates to a laying device, in particular to a laying device for flame-retardant, fire-proof and high-temperature-resistant polyethylene film. Background technique [0002] Polyethylene film refers to a film produced from polyethylene film. Polyethylene film has moisture resistance and low moisture permeability. According to different manufacturing methods and control methods, polyethylene film can produce products with different properties such as low-density, medium-density, high-density polyethylene and cross-linked polyethylene. After pouring large-area ready-mixed concrete, in order to prevent concrete from Concrete shrinkage cracks are caused by the evaporation of water in the water, and maintenance measures are generally taken. The most common method is to cover the concrete surface with a plastic film after the initial setting of the poured concrete. [0003] Common plastic films need to be laid manually. When laying plastic fil...
