Description

Edge-sealing arm bracket on an automatic edge-sealing machine Technical Field

[0001] The present invention relates to the technical field of woodworking machinery, and more specifically to an edge-sealing arm bracket on an automatic edge-sealing machine. Background Art

[0002] An edge-sealing machine is a type of woodworking machinery belonging to the category of solid wood machinery and is used for edge-sealing wooden boards. It is an automated machine that realizes processes such as conveying, gluing and edge-pasting, cutting, front and rear trimming, upper and lower trimming, upper and lower fine trimming, upper and lower scraping, and polishing. Currently, on general edge-sealing machines, the material board to be edge-sealed is generally manually moved for edge-sealing. In order to achieve automatic edge-sealing of the edge-sealing machine, it is proposed to use an elastically pulled rocker arm. The rocker arm is provided with clamps for installing the material board to be edge-sealed and a reference board. The material board to be edge-sealed and the reference board have the same size, and their outer sides are all in the same vertical plane. The reference board abuts against a guide wheel, while the material board to be edge-sealed can abut against a pressing wheel for edge-sealing. Through the self-rotation of the clamp and using the reference board and the guide wheel as a reference and the elastic movement of the rocker arm, automatic edge-sealing of the material board to be edge-sealed can be achieved. Therefore, it is necessary to design a material rack that can conveniently hold the material board to be edge-sealed and the reference board and can rotate the material board to be edge-sealed and the reference board. Summary of the Invention

[0003] The purpose of the present invention is to address the deficiencies of the prior art and provide an edge-sealing arm bracket on an automatic edge-sealing machine, which can conveniently achieve clamping of the material board to be edge-sealed and the reference board and can rotate the material board to be edge-sealed and the reference board, thereby providing a basis for the automatic edge-sealing of the edge-sealing machine.

The upper end of the fixed support shaft is fixedly connected to a transmission shaft, which is rotatably connected to the upper end of the support frame. The first moving support rod has a vertical sleeve formed at the end near the fixed support base. Baffles are formed at the upper and lower ends of the sleeve. A rotating shaft is inserted into the sleeve. The first part has a clamping plate opposite to the fixed pressure plate, which abuts against the baffle plate. The second moving support rod has a moving support seat near the sleeve, and a moving support shaft is inserted into the moving support seat. The upper end of the moving support shaft has a moving pressure plate opposite to the clamping plate. The lower end of the moving support shaft extends out of the moving support seat and is fixed with a lower limit sleeve. The lower end of the moving support shaft has a vertical prism. The lower end of the support frame is rotatably connected to a rotating sleeve. The rotating sleeve has a connecting hole opposite to the prism. The prism on the moving support shaft is inserted into the connecting hole of the rotating sleeve.

[0007] Preferably, the rotatable connection between the rotating sleeve and the support frame is such that the rotating sleeve is shaped like a rotatable sleeve, and the rotating sleeve is inserted into the support frame and a positioning sleeve is fixed thereon.
