[0020] The effects provided in the content of the invention are only the effects of the embodiments, not all the effects of the invention. One of the above technical solutions has the following advantages or beneficial effects:

[0021] 1. The present invention sets a heating cavity on the frame and heats the edge band in the heating cavity through a heating plate, thereby achieving the effect of softening the edge band. The air in the heating cavity is circulated by the rotation of the impeller to ensure that the air temperature in the heating cavity is balanced and the heating effect is improved.

[0022] 2. The present invention increases the heating effect of the heating plate on the preheating disk and the rotating disk by distributing the rotating disk, the preheating disk, the heating plate and the impeller from top to bottom. In addition, by providing the preheating disk, since the preheating time required for the edge banding is relatively high, a prepared edge banding can be preheated while the edge banding in use is heated, thereby saving preheating time and improving work efficiency.

[0023] 3. The present invention provides a temperature controller and a temperature sensor, and the temperature can be set on the temperature controller to automatically control the temperature or start and stop of the heating plate, so that the temperature in the heating cavity is kept constant.

[0024] 4. The present invention can detect whether the edge banding is used up through the commission alarm device. After it is used up, the alarm light is used to remind the operator to replenish the edge banding in time. The second proximity switch can be used to determine whether the first door panel is closed, and when the first door panel is opened, the alarm signal of the edge banding being exhausted is suspended, thereby reducing the light pollution of the alarm light to the operator.

[0025] 5. The impeller drives the gas in the heating cavity to circulate internally to make the heating more uniform. Through the air inlet and the belt conveyor, an external heating circulation mode that continuously delivers hot air to the belt conveyor can be realized. Through the dual effects of internal circulation and external heating, the edge banding has a better bonding effect during bonding. BRIEF DESCRIPTION OF THE DRAWINGS
