Description

The present invention relates to a technical field of waxing sofa leather, specifically, a waxing device for manufacturing sofa leather.

During the production of leather, there is a process of waxing and polishing to make it glossy, and the type of wax varies depending on each craft. Some are solid waxes and some are liquid waxes. If liquid wax is used, the solid wax is melted into a liquid in a container and the liquid wax is sprayed onto the leather or brush. Currently, automatic leather waxing equipment cannot automatically remove the liquid wax in the coating tube after the first waxing, so the liquid wax solidifies and blocks the coating tube, which affects the subsequent processing. There is a flaw that it cannot be applied automatically to different thicknesses of leather and can be manually adjusted and then waxed. The present invention can solve the above problems.

The beneficial effect of the present invention is: In the present invention, after the coating mechanism heats and melts the solid wax, the liquid wax is directly applied to the leather, and the lifting mechanism is driven downward by the air pump, whereby the waxing mechanism is formed. It can move in tandem to wax different thicknesses of leather, while the working pressure adjustment mechanism sets different initial pressures on the springs to create different working pressures between the different waxing mechanisms and the leather. Make a difference, enhance adaptability to different leathers and ensure stability of waxing quality. The waxing mechanism mimics manual waxing by painting in two directions against each other, increasing the uniformity of waxing. After waxing, the airflow of the air pump can transport the liquid wax remaining inside the coating tube of the coating mechanism to the outside and prevent the solidified liquid wax from being blocked.
