Automatic tensioning device for edge sealing belt

Abstract

The embodiment of the invention discloses an automatic tensioning device for an edge sealing belt. The automatic tensioning device comprises a self-tensioning tray, a redirection water supply assembly, a paper folder and an edge sealing pressing roller. An edge sealing belt is wound on the self-tensioning tray; the edge sealing belt sequentially passes through the redirection water supply assembly, the paper folder and the edge sealing pressing roller and is pressed on the gypsum board by the edge sealing pressing roller; the self-tensioning tray comprises a main shaft and a base; the lower end of the main shaft is fixed on the base; a rotating wheel, a tray and a positioning cylinder are rotatably arranged on the main shaft in sequence from bottom to top in a penetrating manner; the rotating wheel is rotatably fixed on the main shaft through a bearing, a coil spring is arranged between the rotating wheel and the main shaft, the tray is connected with the rotating wheel through a bolt,and the edge sealing belt is wound on the positioning cylinder, so that the automatic tensioning of the edge sealing belt is realized, the deviation of the edge sealing belt is avoided, and the edgesealing effect is ensured.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of gypsum board production, in particular to an automatic tensioning device for edge banding. Background technique [0002] Paper-faced gypsum board is made of building gypsum as raw material, mixed with appropriate amount of additives, fibers and foaming agent diluted several times with water, mixed evenly in a mixer, and then processed with special cardboard for surface protection. [0003] In the production process of gypsum board, the board enters the edge banding process after sawing on both sides. The steps of this process are that the board is edge-sealed while walking. After the edge-seal is completed, it goes to a certain position and stops. The cutting device cuts off the edge-sealed belt, and then the board continues to walk and enters the pallet for palletizing. During the process from the edge sealing of the board to the stop of the board, due to inertia, a part of the...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides an automatic tensioning device for edge banding to solve the problem of slack in the stretched edge banding due to inertia in the prior art when the plate stops, and the edge banding no longer There is a pulling force, which causes the deviation of the edge banding and affects the effect of the edge banding
