The receiving plate and the top plate are connected; the top plate is provided with four limit sliding posts on the side facing the receiving plate;

7. The receiving mechanism includes a connecting bottom plate, a receiving table, and a fixing component; the receiving table is connected to the receiving plate through the connecting bottom plate; the receiving table is provided with a receiving groove, and the receiving groove is used for receiving processing Plastic parts; the fixing assembly is arranged in the receiving groove; the fixing assembly includes a compression spring and a fixing plate, the fixing plate is elastically connected to the inner side wall of the receiving groove through the compression spring;

8. The drive mechanism includes an electric assembly, a manual assembly, a worm gear module, and a drive screw; the electric assembly includes a drive motor, a first drive gear, a transmission chain, and a second drive gear; the drive motor and the support The bottom frame is connected, the driving motor is drivingly connected to the first driving gear, the first driving gear and the second driving gear are both adapted to the transmission chain, and the first driving gear passes through the The transmission chain is drivingly connected to the second driving gear; the second driving gear is drivingly connected to the driving screw through the worm gear module, and the end of the driving screw away from the worm gear module is connected to the top plate Rotating connection; the manual assembly includes a rotating rod, a rotating seat, and a rotating handle; the rotating seat is connected to the connecting base plate, and the rotating rod passes through the rotating seat and is connected to the

The rotating base is connected in rotation, one end of the rotating rod is connected with the second drive gear, and the other end of the rotating rod is connected with the rotating handle;

9. The connecting plate of the hot melt module is provided with threaded holes and four sliding holes, the threaded holes are matched with the drive screw, and the drive screw is inserted into the threaded hole and connected with the The connecting plate of the hot melt module is drivingly connected; the sliding hole is adapted to the limit sliding post, and each limit sliding post is inserted in one of the sliding holes and connected with the hot melt module The board is connected by sliding.

10. In one of the embodiments, the fixing assembly includes a plurality of the compression springs, and the fixing plate is elastically connected to the inner side wall of the receiving groove through each of the compression springs.

11. In one of the embodiments, each of the compression springs is uniformly arranged on the fixing plate.

12. In one of the embodiments, a cushion pad is provided on the side of the fixing plate facing away from the compression spring.

13. In one of the embodiments, the cushioning pad is a soft plastic pad.

14. In one of the embodiments, the cushioning pad is a soft rubber pad.

15. In one of the embodiments, the cushioning pad is a soft silicone pad.

16. In one of the embodiments, anti-slip patterns are provided on the cushion pad.

17. In one of the embodiments, the turning handle is a steering wheel handle.

18. In one of the embodiments, a rolling bearing is provided in the rotating seat, the rolling bearing is adapted to the rotating rod, and the rotating rod is inserted in the rolling bearing to rotate relative to the rotating seat.

19. During the working process of the above-mentioned hot melt machine which is convenient for manual operation, the plastic part to be processed is placed in the receiving groove. During the process of placing the plastic part to be processed, the plastic part to be processed is used to push the fixed plate to compress the compression spring sports. Under the action of the elastic force of the compression spring, the fixing plate is squeezed and fixed to the plastic part to be processed. The driving motor is drivingly connected with the first driving gear, and the first driving gear is drivingly connected with the second driving gear through a transmission chain. The second driving gear is drivingly connected with the driving screw through the worm gear module. Using the principle of the screw rod, the screw rod is driven to drive the hot-melt module to move close to the receiving table; the hot-melt module melts the plastic parts to be processed in the receiving groove. When the driving motor fails or the transmission chain is broken, the rotation lever can be rotated by turning the handle to drive the second driving gear to rotate, and the distance between the hot melt module and the receiving table can also be accurately adjusted. The above-mentioned heat-melting machine that is convenient for manual operation can precisely adjust the distance between the heat-melting module and the receiving table using two adjustment methods, electric and manual, and is suitable for high-precision processing operations.
