Description

Technical Field

[0001] The utility model relates to the technical field of wood-plastic board conveying equipment, in particular to a traction mechanism for producing wood-plastic boards. Background Art

[0002] Wood plastic board, also known as wood plastic composite board, is a high-tech green and environmentally friendly new decorative material that combines the characteristics of wood and plastic. It is mainly made of wood (such as wood cellulose, plant cellulose, etc.) and thermoplastic polymer materials (such as polyethylene, polypropylene and polyvinyl chloride and other plastics), mixed with processing aids, and then heated and extruded by mold equipment. In the process of producing wood plastic board, it is usually necessary to use a tractor to pull the board extruded by the extruder.

[0003] According to the search, Chinese patent literature, announcement number: CN214926943U, discloses a high-stability traction machine for plastic sheet production. By setting up a U-shaped frame, a conveying roller, a return block, a moving block, a through-port, a clamping mechanism and a transmission mechanism for coordinated use, the user places the sheet on the top of the conveying roller, and the conveying roller pulls the sheet. During the traction process, the sheet will tilt on the top of the conveying roller, and the multi-stage electric cylinder is started. The output end of the multi-stage electric cylinder drives the connecting plate, the moving block and the pulley to move, and at the same time drives the hollow plate and the sliding column, the cross plate, and the reinforcing plate to move. The cross plate drives the transmission rod to move, and the transmission rod drives the rotating plate to rotate. When the sliding column contacts the sheet, the position and angle of the sheet are corrected, and the sheet is limited during the movement, which has the advantage of facilitating the stable movement of the sheet.

[0004] However, in actual use, the traction machine is difficult to achieve traction only through a single-side conveyor roller because the wood-plastic board has just been extruded from the extruder and has not yet been fully shaped. In addition, it is relatively cumbersome to use a slide column to adjust the wood-plastic board before limiting it. Utility Model Content
