One end of the feeding hopper 4 extends into the feeding opening at the top of the molten glue tank 1, and the cut potting sealant falls into the inside of the molten glue tank 1 with the one end of the feeding hopper 4, thereby effectively increasing the heating area of the potting sealant and accelerating the melting state of the potting sealant. Avoiding the situation that the solid potting sealant has a large volume in the storage state, the heating area is small when it is accumulated in the molten glue tank 1, and the melting time is long. When the cut solid potting sealant enters the molten glue tank 1, the inside of the molten glue tank 1 is heated and treated by the external power supply and the heating pipe 12.

At the same time, the external power supply and the two first connecting heads 902 on the heating assembly 9 are electrically connected and powered on to heat the first connecting head 902 and the extension pipe 903, thereby facilitating the simultaneous heating and melting treatment of the potting sealant accumulated in the molten glue tank 1, further improving the heating effect of the device, and shortening the heating time. In order to improve the working efficiency of the potting sealant melting, the cutting assembly 5 and the swing assembly 8 are connected to each other, and the swing assembly 8 is driven to run by the power source generated by the operation of the cutting assembly 5, thereby facilitating the two heating assemblies 9 arranged in the molten glue tank 1 to swing left and right in the molten glue tank 1 to disturb and stir the potting sealant heated in the molten glue tank 1, thereby avoiding the deposition of the potting sealant in a fluid state. When the potting sealant in the molten glue tank 1 is heated and melted, the staff manually opens the valve 15 to facilitate the discharge of the potting sealant in a fluid state in the molten glue tank 1. During the discharging process of the device, the heating assembly 9 is operated to drive the scraper rod 905 on the heating assembly 9 to swing synchronously, and the scraper rod 905 is in close contact with the inner wall of the molten glue tank 1, thereby facilitating the scraping of the material adhered to the inner wall of the molten glue tank 1, avoiding the large amount of residual potting sealant in the molten glue tank 1, and achieving good cleaning and discharging effect.

2. The household appliance circuit board potting adhesive melting device according to claim 1, characterized in that, A second connector (13) is fixed to one side of the outer wall of the melt glue tank (1), and the second connector (13) is electrically connected to the heating tube (12).

3. The potting compound melting device for household appliance circuit boards according to claim 1, characterized in that, The bottom of the melt tank (1) is fixed with a discharge pipe (14), and a valve (15) is provided on the discharge pipe (14).

4. The potting compound melting device for household appliance circuit boards according to claim 1, characterized in that, The bottom of the mounting plate (2) is fixed with a support column (16), and the bottom of the support column (16) is provided with an anti-slip sleeve.

5. The potting compound melting device for household appliance circuit boards according to claim 1, characterized in that, The top surface of the support frame (3) has an opening (17), through which the belts on the surfaces of the drive wheel (801) and the driven wheel (802) pass.

6. The method of using the potting compound melting device for household appliance circuit boards according to claim 1, characterized in that, Includes the following steps: Step A: When using, the worker inserts the solid columnar potting compound into the inside of the feed hopper (4) through the feed pipe (10). Using the cutting component (5) set on the support frame (3), the solid potting compound is cut into small pieces by the rotating cutting blade (504) on the cutting component (5). One end of the feed hopper (4) extends into the feed port at the top of the melting tank (1). The cut potting compound rolls down into the inside of the melting tank (1) along with one end of the feed hopper (4). This avoids the situation in the traditional method where the solid potting compound has a large volume in the storage state, resulting in a small heating area and a long melting time in the melting tank (1). Step B: When the cut solid potting compound enters the melting tank (1), it is heated by an external power supply and a heating tube (12) to heat the inside of the melting tank (1). At this time, the outer surface of the potting compound placed inside is heated and melted into a fluid state. At the same time, the external power supply is electrically connected to the two first terminals (902) on the heating component (9) to heat the first terminals (902) and the extension tube (903), so as to facilitate the simultaneous heating and melting of the potting compound accumulated in the melting tank (1) and shorten the heating time. Step C: Through the mutual linkage of the cutting component (5) and the swing component (8), the power source generated by the operation of the cutting component (5) drives the swing component (8) to run, thereby facilitating the two heating components (9) set in the melt glue tank (1) to swing back and forth in the melt glue tank (1) to disturb and stir the heated potting glue in the melt glue tank (1), thereby avoiding the deposition of the fluid potting glue. After the potting glue in the melt glue tank (1) has been heated and melted, the staff can manually open the valve (15) to facilitate the discharge of the fluid potting glue in the melt glue tank (1). During the discharge process, the operation of the heating component (9) simultaneously drives the scraper (905) on the heating component (9) to swing synchronously. The scraper (905) is in contact with the inner wall of the melt glue tank (1), thereby facilitating the scraping of the material adhering to the inner wall of the melt glue tank (1) and avoiding a large amount of residual potting glue in the melt glue tank (1).
