[0026] In the glue melting equipment, the raw materials are poured into the glue melting tank 2 through the feed port 3, and the output end of the motor 4 drives the rotating shaft 5 to start rotating. As the rotating shaft 5 rotates, the connecting rod 6 also starts to rotate and further drives the mounting plate 7 to rotate. The rotation of the mounting plate 7 drives the scraper 8 to rotate. While the connecting rod 6 rotates, the raw materials in the glue melting tank 2 are uniformly stirred to ensure that the raw materials can be fully melted and mixed. As the scraper 8 rotates, any residue on the inner wall of the glue melting tank 2 will be effectively removed. The rotation of the rotating shaft 5 also drives the rotation of the fixing ring 9, and the rotation of the fixing ring 9 further drives the fixing rod 10 to rotate. The rotation of the fixing rod 10 makes the scraper 2 11 rotate inside the glue melting tank 2. The scraper 2 11 works together with the scraper 1 8 to clean the inner wall of the glue melting tank 2, thereby ensuring that no glue residue remains inside the glue melting tank 2.

When the motor 23 is started, the active bevel gear 24 will be driven to rotate, and the active bevel gear 24 and the driven bevel gear 25 are meshed with each other. Therefore, when the active bevel gear 24 rotates, the driven bevel gear 25 will also rotate accordingly. When the driven bevel gear 25 rotates, it will drive the threaded rod 26 to rotate together. When the threaded rod 26 rotates, the moving rod 27 will move along the axial direction of the threaded rod 26. When the moving rod 27 moves, the block 28 will slide inside the slot 29, thereby ensuring that the moving trajectory of the moving rod 27 is stable and reliable. Under the action of the block 28, the moving rod 27 drives the heating tank 1 to move up and down.

Water is added to the interior of the heating tank 1 through the water inlet pipe 16. Under the action of the heating tube 19, the cold water can be heated. After the water cup is heated, the melt glue tank 2 is heated, so that the raw materials inside the melt glue tank 2 are heated. The fixing box 18 fixes the heating tube 19, and the used water can be discharged through the water outlet pipe 17. Turn the handle 13, the handle 13 drives the rotating rod 14 to rotate, and the rotation of the rotating rod 14 drives the baffle 15 to rotate, so that the raw materials inside the melt glue tank 2 are discharged.
