Placement traction device for modified PBAT film production

Abstract

The invention relates to the technical field of film production, and discloses a placement traction device for modified PBAT film production, which comprises two groups of support plates symmetrically arranged on a bottom plate, assembly grooves are embedded in opposite sides of the two groups of support plates, a traction shaft is slidably assembled and connected to the two groups of assembly grooves, and a plurality of groups of separation blades are slidably matched and connected to the traction shaft. A clamping ring matched with the traction shaft in a limiting mode is coaxially and fixedly connected to one side of the blocking piece, a clamping groove is formed in the position, close to the traction shaft, of the other side of the blocking piece in an embedded mode, and a clamping piece used for limiting the tail end of a wound material is rotationally connected into the clamping groove. The width of the separation blades can be flexibly adjusted according to whether the separation blades are cut or not and the width of a film, after the position is fixed through the clamping ring, the film is wound between the separation blades, the end of the film is limited by rotating the clamping pieces embedded in the side faces of the separation blades, and therefore winding can be stable conveniently.

Description

technical field [0001] The invention relates to the technical field of film production, in particular to a placement and traction device used for the production of modified PBAT films. Background technique [0002] The molecular chain of PBAT contains aromatic rings and aliphatic segments, which have good ductility and elongation at break, so it can be used as a film material, but the melt strength of PBAT is low, and the film bubble is unstable and easy to swing, resulting in film thickness The deviation is large. Therefore, the stability of PBAT film can be improved by blending with other degradable polyesters to replace traditional packaging materials. The price of PBAT is relatively high, and the price can be reduced by adding fillers, which can not only reduce the cost, but also increase the compatibility and obtain better film materials. [0003] A film scrap pulling mechanism disclosed in Chinese Patent Publication No. CN213445460U mainly includes a first cutting ro...
