[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-5 As shown, the glue gun structure for a hot melt glue machine includes a main body 1. A glue gun cover 2 is located at the upper end of the main body 1, and a glue gun threaded base 6 is located at the lower end of the main body 1. Two sets of glue gun plastic shells 14 are snapped onto the front wall of the main body 1. A glue gun original adjusting screw 4 is located at the upper end of the glue gun cover 2. Each of the two sets of glue gun plastic shells 14 has a set of hexagonal Torx screws 15, which pass through the plastic shells 14 and connect to the side wall of the main body 1. A set of spring washers 13 is located at each of the two corners of the glue gun cover 2. A set of Phillips head screws 16 is located inside each of the two spring washers 13, which pass through the glue gun cover 2 and connect to the main body 1. A set of glue gun screws 11 is located at each of the four corners of the glue gun threaded base 6, which pass through the threaded base 6 and connect to the main body 1.

[0021] In this embodiment, the glue gun threaded base 6 can be disassembled and installed by setting glue gun screws 11, the two sets of glue gun plastic shells 14 can be disassembled and installed by setting hexagonal screws 15, and the glue gun top cover 2 can be disassembled and installed by setting multiple sets of Phillips head screws 16. This facilitates the installation and removal of the glue gun top cover 2 and the glue gun threaded base 6, allowing workers to easily disassemble and install the glue gun structure, enabling them to repair the internal components of the main body 1, thus improving the maintainability and service life of the equipment. Furthermore, the carefully designed component structure, such as the fastening effect of glue gun screws 11 and hexagonal screws 15, ensures a stable connection between various components, avoiding performance degradation or safety hazards caused by loosening. The multiple sets of glue gun screws 11 and hexagonal screws 15 facilitate the disassembly and installation of the glue gun top cover 2 and the glue gun threaded base 6, allowing workers to easily disassemble and install the glue gun structure, enabling them to repair the internal components of the main body 1, thus improving the maintainability and service life of the equipment. Not only does it facilitate disassembly and installation, improving maintenance convenience, it also ensures the stability and durability of the equipment.

[0022] Furthermore, a third sealing ring 19 is provided at the connection between the glue gun cover 2 and the glue gun original adjusting screw 4. Multiple sets of internal hexagon screws 12 are provided in the middle of the main body 1, and a first sealing ring 17 is fitted onto one end of each set of internal hexagon screws 12. An upper cover spring 10 is provided on the inner wall of the upper end of the glue gun original adjusting screw 4. A pointed pin 8 is provided at the lower end of the upper cover spring 10. A glue gun star-shaped retaining spring 3 is fitted on the outer side of the pointed pin 8, and a glue gun lower washer 5 is provided at the lower end of the glue gun star-shaped retaining spring 3. A fourth sealing ring 20 is fitted onto the upper end of the pointed pin 8. A second sealing ring 18 is provided at the upper end of the glue gun threaded base 6. A glue gun steel sleeve 7 is provided inside the second sealing ring 18. A glue path spring 9 is provided at the upper end of the glue gun steel sleeve 7. A glue gun lower washer 5 is provided at the upper end of the glue path spring 9, and an oil seal 21 is provided at the upper end of the glue gun lower washer 5. The inclusion of the first sealing ring 17, the second sealing ring 18, the third sealing ring 19, and the fourth sealing ring 20 effectively prevents hot melt adhesive leakage under high pressure, ensuring the sealing performance and work efficiency of the glue gun. The oil seal 21 further enhances the leak-proof performance of the equipment, making the hot melt adhesive machine more stable and reliable during operation.

[0023] In practice, it is necessary to connect the fixed mounting holes on the glue gun with the glue spraying position. Two wrenches are needed to install the automatic glue gun and glue hose connector. When disassembling, run the glue machine to empty, disconnect all interfaces of the glue machine, and wait for the glue machine to cool down before starting work.
