Description

Technical Field

[0001] The utility model relates to the field of high-density polyethylene film production, in particular to a film-drawing machine which is convenient for cutting. Background Art

[0002] High-density polyethylene film generally refers to HDPE geomembrane. HDPE geomembrane is one of the geosynthetics. High-density polyethylene (HDPE) is a white powder or granular product. Its hardness, tensile strength and creep are better than those of low-density polyethylene. It has good wear resistance, electrical insulation, toughness and cold resistance. At room temperature, it is insoluble in any organic solvents and is resistant to corrosion by acids, alkalis and various salts. The film has low permeability to water vapor and air and low water absorption. In order to facilitate the use of high-density polyethylene film in the production process, staff usually use a film stretching machine to stretch the high-density polyethylene film.

[0003] However, the current film stretching machines still have some shortcomings. For example, a longitudinal stretching machine for stretching polyethylene film with application number 202022034974.5 has not fully considered the cutting structure of the film stretching machine. In the process of producing high-density polyethylene film using the film stretching machine, if the cutting structure of the film stretching machine is not fully considered, the high-density polyethylene film may be offset or wrinkled during the cutting process, resulting in cutting failure, which is inconvenient for staff to use the film stretching machine.
