[0022] A workpiece fixing jig is provided on the workbench, and the position of the workpiece fixing jig can be adjusted according to the workpiece to be processed, and the workpiece fixing jig can be fixed to the workbench by bolts. The structure of the workpiece fixing jig needs to be set according to the workpiece to be hot-melt processed. As a preferred embodiment, the workpiece fixing jig includes a front fixing jig and a rear fixing jig, and positioning grooves matching the shape of the workpiece are respectively provided on the front fixing jig and the rear fixing jig. Through this arrangement, a stable support can be provided to the workpiece, so that the clamping of the workpiece on the workpiece fixing jig is more stable.

[0023] The hot melt assembly includes a column, a fixed seat plate, a lifting seat plate, a lifting control component, a heating plate and a hot melt head.

[0024] The column has the required strength, is vertically fixed on the workbench, and is fixedly connected to the workbench by welding, threaded connection, or flange surface and bolt connection.

[0025] The number of columns can be set as needed. If one column is set, the column is set in the middle of the lifting seat plate. If two columns are set, the two columns are respectively set on the left and right sides of the lifting seat plate.

[0026] The fixed seat plate is fixedly connected to the top of the column, and the fixed seat plate can be made of a plate with a certain strength.

[0027] The lifting control component is fixedly arranged on the fixed seat plate, and the lifting control component is used to control the lifting and lowering movement of the lifting seat plate. The lifting control component can select a component that can control the lifting and lowering movement of the lifting seat plate, such as a cylinder, an oil cylinder or an electric telescopic rod. The shell of the lifting control component is fixedly arranged on the fixed seat plate, and the telescopic rod of the lifting control component extends downward through the through hole on the fixed seat plate, and the lower end of the telescopic rod is fixedly connected to the lifting seat plate. As a preferred embodiment, the telescopic length of the telescopic rod of the lifting control component can be adjusted, so that the lifting height of the lifting seat plate can be adjusted according to the workpiece to be hot-melt processed.

[0028] The lifting seat plate is sleeved on the column, and a through hole is provided on the lifting seat plate for the column to pass through.
