[0039] Working principle: When this utility model is used, the fixing ring 51 is installed on the side wall of the injection head 4. The fixing ring 51 limits the injection head 4. When the injection head 4 is installed, it is inserted into the discharge pipe 3. The injection head 4 opens the two clamping rods 52. The clamping rods 52 drive the lifting frame 53 to rise and fall, compressing the spring 54. After the injection head 4 is installed, under the elastic force of the spring 54, the clamping rods 52 move towards the injection head 4 to limit the injection head 4. During the rising and falling process, the guide rod 56 guides the clamping rods 52.

[0040] The injection molding machine body 2 discharges the injection molding tube 6 through the discharge pipe 3 and the injection head 4.

The moving frame 104 drives the upper limit plate 106 to move, and the limit plate 106 drives the injection tube 6 to move, so that the injection tube 6 can be wound on the rotating rod 15. By rotating the adjusting frame 105, the adjusting frame 105 and the moving frame 104 have a threaded movement, and the adjusting frame 105 drives the limit plate 106 to move, so that the limit plate 106 can limit the injection tubes 6 of different diameters. When the limit plate 106 moves, the slide rod 107 plays a guiding role. The mounting plate 11 installs the glue dispensing hopper 12, which drips glue onto the surface of the injection tube 6. Excess glue falls into the collection tank 14. The side plate 13 installs the moving assembly 10, the rotating motor 16 and other components. The rotating motor 16 drives the rotating rod 15 to rotate, and the rotating rod 15 screws and fixes the injection tube 6.
