Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, specifically to a multi-angle adjustable automatic guiding coating equipment and coating method for wood-plastic door frames. Background Technology

[0002] During the manufacturing process of wooden doors, in order to enhance the waterproof performance of the wooden door frame, it is necessary to cover the outer surface of the door frame with a film. During the film covering process, a PVC film needs to be covered on the outer surface of the door frame.

[0003] For example, the door frame film-coating roller structure disclosed in Chinese patent CN213291667U, which facilitates angle adjustment, includes a bottom support base. A main column is supported and installed on the bottom support base. A first crossbar is supported and installed in the middle of the main column through a first connecting bracket. A horizontal roller assembly is installed at the end of the first crossbar. A second connecting bracket is fixed to the top of the main column. A second crossbar is installed on the second connecting bracket. A horizontal bar is installed on the second crossbar through a third connecting bracket. A fourth connecting bracket is fixed to the end of the horizontal bar. An inclined support rod is installed on the fourth connecting bracket. An inclined roller assembly is fixed to the end of the inclined support rod. This pressure roller structure can be used for the lamination process of door frames, thereby greatly improving the lamination quality and efficiency. It can also adapt to lamination of door frames of different sizes and models, and is suitable for lamination of recessed areas. Traditional door frame conveying uses rotating wheels for transport, but the wheel support surface is small, mainly used to support the ends of the door frame. During the lamination process, pressure rollers are needed to press the protective film on the surface, but the lower support force is small, making deformation easy. Furthermore, different door frame specifications require different wheel support positions, resulting in a lack of stability. Therefore, a multi-angle adjustable automatic guiding lamination device and its lamination method for wood-plastic door frames are proposed to solve the above problems. Summary of the Invention
