Problems solved by technology

At present, the film feeding roller used by the coating machine is a smooth iron roller. After the PE film is wrapped around the iron roller, it is easy to produce film slippage, so that the PE film with glue cannot be flatly attached to the smooth iron roller, that is, The PE film is easy to wrinkle after slipping, and usually the PE film is sent to the drying mechanism after passing the 90-degree turn of the film-feeding roller after passing the glue roller, so the contact area between the PE film and the film-feeding roller is small, which makes the film heavier Severity of slippage problem

Abstract

A coater for making a preservative film mainly comprises a film unrolling mechanism provided with a PE film reel, at least two rotating rollers arranged at two sides of a glue coating roller, a film conveying roller, a drying mechanism and a film rolling mechanism; the glue coating roller is positioned at the upper portion of a glue solution tank, at least parts of the glue coating roller is immersed in the glue solution of the glue solution tank, the film conveying roller is an iron roller with the surface wound with a band or is a rubber-plastic roller with a rough surface, and the film conveying roller is post-positioned relative to the film conveying direction in order to make an angle between a solution coated PE film and the film conveying roller less than 90DEG; two sides of the glue coating roller are respectively provided with the rotating rollers for wire-wrapping and conveying the PE film, the positions of the two rotating rollers allow the PE film wire-wrapped to the rotating rollers to be overlaid to the upper roller surface of the glue coating roller placed between the two rotating rollers by using the self movement tensioning force of the PE film, the PE film contacts with the front rotating roller in front of the glue coating roller, and the upper surface of the front rotating roller wire-wraps the PE film; and the PE film contacts the rear rotating roller from the glue coating roller, and the lower surface of the rear rotating roller wire-wraps the PE film. The coater has the characteristics of simple structure, use convenience, solving of the sliding problem of the PE film in the transmission process, and stable and reliable coating quality.

Description

technical field [0001] The invention relates to a coating machine for making plastic wrap, and belongs to the technical field of plastic wrap production. Background technique [0002] The cling film is mainly made of high-pressure polyethylene (PE) raw materials. In the process of making the cling film, at least one surface of the PE film needs to be coated with an adhesive film layer. This film coating process is mainly realized by using a coating machine. , the existing coating machine mainly includes: a film releasing mechanism, at least two rotating rollers that are placed on both sides of the glue roller, a film feeding roller, a drying mechanism and a film rolling mechanism; the glue roller is located in the glue tank and at least partially submerged in the glue in the glue tank, through the rotation of the glue roller, the glue in the glue tank is brought to the glue roller, and the glue is applied until it is close to the glue roller On the surface of the moving PE ...
