Description

Technical Field

[0001] The utility model relates to the technical field of protective film blown film processing equipment, in particular to a herringbone row for protective film blown film processing. Background Technique

[0002] The film produced by the blown film machine is suitable for various high-grade film packaging. Due to its good barrier property, freshness preservation, moisture prevention, frost prevention, oxygen isolation, and oil resistance, this film can be widely used for heavy and light packaging. During the processing of the blown film machine, the film needs to be cooled by the air ring, blown up, and conveyed through the herringbone row to meet the requirements of film production. A good herringbone row can improve the production efficiency of the film, reduce the production difficulty, and bring good economic benefits to the enterprise.

[0003] In general, the herringbone row on the market is used as an extrusion conveying device. When passing through the herringbone row, the conveying roller squeezes out the gas inside the film, and the film undergoes a certain amount of shrinkage deformation, resulting in insufficient tensile power during the conveying process of the film, causing film wrinkles and requiring further processing of the film, which brings trouble to users. For this reason, we propose a herringbone row for protective film blown film processing. Content of the Utility Model

A plurality of the synchronous gears are evenly arranged on the inner wall sides of the first conveying row and the second conveying row. The power input end of the conveying roller is connected with the power shaft of the servo motor. The first conveying row and the second conveying row are distributed in a herringbone shape, and the included angle between the first conveying row and the second conveying row is for squeezing and conveying the protective film.
