[0025] Please refer to Figures 1, 2, 3, 4, and 5. Figure 1 is a schematic diagram of the overall structure of the improved extruder head provided by this utility model; Figure 2 is a cross-sectional schematic diagram of the improved extruder head provided by this utility model; Figure 3 is an enlarged schematic diagram of part A in Figure 2; Figure 4 is a schematic diagram of the structure of the extruder head in this utility model; and Figure 5 is a partial schematic diagram of the structure of the improved extruder head provided by this utility model. The improved extruder head includes: a body 1, an extruder head 2 provided at the discharge end of the body 1, a connecting groove 3 provided on the body 1, one end of the extruder head 2 extending into the connecting groove 3, and two connecting mechanisms, a cutting mechanism, and two pushing mechanisms provided on the body 1 and the extruder head 2.

[0026] The connecting mechanism includes a cavity 4, a circular plate 5, a telescopic spring 6, a slot 7, and a connecting post 8. The cavity 4 is formed on the extrusion head 2. The circular plate 5 is slidably installed inside the cavity 4. The telescopic spring 6 is fixedly installed on the bottom of the circular plate 5, and the bottom end of the telescopic spring 6 is fixedly connected to the bottom inner wall of the cavity 4. The slot 7 is formed on the inner wall of the connecting groove 3. The connecting post 8 is fixedly installed on the top of the circular plate 5, and the top end of the connecting post 8 extends into the slot 7 and is adapted to the slot 7.

[0027] As shown in Figure 5, the cutting mechanism includes a C-shaped frame 9, a fixed plate 10, an electric telescopic rod 11, a rectangular plate 12, a servo motor 13, a drive shaft 14, and a cutter 15. The C-shaped frame 9 is mounted on the machine body 1. The fixed plate 10 is fixedly mounted on the top of the C-shaped frame 9. The electric telescopic rod 11 is fixedly mounted on the fixed plate 10. The rectangular plate 12 is fixedly mounted on the output shaft of the electric telescopic rod 11. The servo motor 13 is fixedly mounted on the rectangular plate 12. The drive shaft 14 is fixedly mounted on the output shaft of the servo motor 13. The cutter 15 is fixedly mounted on the drive shaft 14.

[0028] By setting up a cutting mechanism, the plastic can be cut after extrusion to form plastic pellets.

[0029] As shown in Figure 3, the pushing mechanism includes a strip-shaped limiting groove 16, a strip-shaped push plate 17, a threaded rod 18, and a handwheel 19. The strip-shaped limiting groove 16 is formed on the machine body 1. The strip-shaped push plate 17 is slidably installed in the strip-shaped limiting groove 16. The threaded rod 18 is rotatably installed on the top of the strip-shaped push plate 17. The top end of the threaded rod 18 extends to the outside of the machine body 1 and is threadedly connected to the machine body 1. The handwheel 19 is fixedly installed on the top end of the threaded rod 18.

[0030] By setting up a pushing mechanism, when replacing the extruder head 2, the handwheel 19 drives the threaded rod 18 to rotate, causing the strip pusher plate 17 to move down and push the connecting column 8 back into the cavity 4. Then, the extruder head 2 can be pulled out of the connecting groove 3 for replacement.

[0031] As shown in Figure 1, two mounting seats 20 are symmetrically installed on the outer wall of the body 1, and two bolts 21 are installed on the shaped frame 9. The bolts 21 fix the shaped frame 9 to the two mounting seats 20.

[0032] By providing the mounting base 20 and bolts 21, the cutting mechanism can be mounted on the machine body 1 when it is necessary to cut the extruded plastic.

[0033] As shown in Figures 3 and 4, two positioning holes are provided on the inner wall of the connecting groove 3, and two positioning posts 22 are fixedly installed on the extrusion head 2, the positioning posts 22 being adapted to the positioning holes;

[0034] By setting positioning holes and positioning posts 22, the angle of the extrusion head 2 can be limited when it is inserted into the connecting groove 3, so that the connecting post 8 can be directly facing the slot 7.

[0035] As shown in Figures 1 and 2, the extrusion head 2 has multiple extrusion holes;

[0036] By setting an extrusion orifice, the plastic can be extruded through the extrusion orifice when the molten plastic enters the extrusion head 2.

[0037] The working principle of the improved extruder head provided by this utility model is as follows:

[0038] First step: When the extruder head 2 needs to be replaced according to the different particle size of the plastic granules to be produced, the handwheel 19 drives the threaded rod 18 to rotate, causing the strip push plate 17 to move down and push the connecting post 8 back into the cavity 4. Then the extruder head 2 can be pulled out of the connecting groove 3. Then take out the extruder head 2 of the required particle size, press the connecting post 8 to make the connecting post 8 retract into the cavity 4, and compress the telescopic spring 6. Then insert the extruder head 2 into the connecting groove 3. Under the action of the elastic force of the telescopic spring 6, the circular plate 5 and the connecting post 8 pop out and reset, and insert into the slot 7, completing the replacement of the extruder head 2 of the required particle size.

[0039] The second step: When the plastic needs to be cut during extrusion, the electric telescopic rod 11 is activated. The electric telescopic rod 11 drives the rectangular plate 12, servo motor 13, drive shaft 14 and cutter 15 to move, so that the cutter 15 is close to the extrusion head 2. The servo motor 13 is activated, and the servo motor 13 drives the drive shaft 14 to rotate. The drive shaft 14 drives the cutter 15 to rotate, thereby cutting the extruded plastic and forming plastic granules.
