In order to improve the polishing effect, the polishing plate 33 can be arranged in an angle-adjustable structure to adapt to wood-plastic composite boards of different shapes and sizes.

[0042] Working process:

[0043] When the wood-plastic composite board needs to be coated, the wood-plastic composite board is first placed on the base 1. The motor of the polishing assembly 3 is started, the rotating cylinder 31 drives the polishing plate 33 to start rotating, and the operator manually rotates the stand 26 to make the polishing plate 33 comprehensively polish and pretreat the surface of the wood-plastic composite board, remove impurities and uneven parts on the surface, and increase the roughness of the surface.

[0044] After polishing, the rotating stand 26 is rotated to move the polishing assembly 3 away.

[0045] Then, the rotating sleeve 25 is rotated to move the pressing cap 22, and the pressing plate 21 is aligned with the wood-plastic composite board. The heating wire is started, the pressing plate 21 is heated to a set temperature, and then pressure is applied downward to perform hot pressing and coating operation on the wood-plastic composite board.

When the motor in the rotating cylinder 31 is started, the transmission roller 36 is driven to rotate through the belt drive, and the polishing belt 34 is driven to circulate, thereby polishing the surface of the wood-plastic composite board placed on the base 1.

[0054] The top of the cover 22 is provided with a lifting ring 23 and a handle 24. The lifting ring 23 is arranged on both sides of the top of the cover 22, and the handle 24 is used to press the cover 22 to drive the pressing plate 21 to perform heat pressing treatment on the target object.

[0055] The top of the cover 22 is provided with a lifting ring 23 and a handle 24. The lifting ring 23 is arranged on both sides of the top of the cover 22, and the handle 24 is used to press the cover 22 to drive the pressing plate 21 to perform heat pressing treatment on the target object.

[0056] The telescopic part 32 at the top of the polishing plate 33 is designed to allow the polishing plate 33 to be flexibly adjusted in position according to the thickness and size of different wood-plastic composite boards, improving the adaptability and accuracy of polishing and better meeting diversified production needs, avoiding the problems of insufficient or excessive polishing due to improper polishing position.

[0057] The combination of the positioning hole 35, the transmission roller 36 and the polishing belt 34 of the polishing area 37 realizes efficient polishing operation. The transmission roller 36 drives the polishing belt 34 to circulate, which can continuously and stably polish the surface of the wood-plastic composite board, improving the polishing efficiency and quality and helping to increase the roughness and activity of the board surface, providing a good foundation for subsequent hot-pressing coating.
