The extrusion end of the extrusion system 11 is provided with a head mechanism 2. The head mechanism 2 facilitates the replacement of the head of the thermoplastic elastomer extruder.

[0026] The head mechanism 2 includes a connecting head 21 and a limit block 22, which are respectively installed at the extrusion end of the extrusion system 11. The connecting head 21 is used to guide the insertion support of the extruder head 23, and the limit block 22 is used to limit the insertion position of the extruder head 23 so that the extrusion port on the extruder head 23 can be aligned with the extrusion port on the extrusion system 11. The connecting head 21 and the limit block 22 are slidably inserted into the extruder head 23 and magnetically adsorbed to limit the extruder head 23. An electromagnet 231 is installed on the top of the extruder head 23. After the electromagnet 231 is energized to generate magnetism, it is used to magnetically connect to the magnet rod 242;

[0027] Furthermore, a first support plate 24 is installed on the top of the base 1 by bolts. The first support plate 24 is used to support and install the first hydraulic rod 241. The first hydraulic rod 241 is installed on the first support plate 24. The first hydraulic rod 241 is used to push and pull the magnet rod 242, drive the magnet rod 242 to be inserted into the electromagnet 231, and the output end of the first hydraulic rod 241 is installed with a magnet rod 242. The magnet rod 242 is used to push the extruder head 23, so that the extruder head 23 is pushed onto the slide 26. The magnet rod 242 is used to be inserted into the electromagnet 231 to push the extruder head 23. The top of the base 1 is installed with The first support rail 25, the extruder head 23 slides on the first support rail 25 and is inserted into the connecting head 21 and the limit block 22. The extruder head 23 is also supported and moved by the first support rail 25 when exiting. The first support rail 25 is arranged below the connecting head 21 to support the movement of the extruder head 23. An inclined slide 26 is installed at one end of the first support rail 25. The slide 26 and the limit plate 261 guide the extruder head 23 to slide into the pool 29. A limit plate 261 is installed on the top of the slide 26. The limit plate 261 is used to guide the extruder head 23 so that the extruder head 23 can The extruder head 23 to be replaced is placed on the top of the base 1, and the edge of the second support rail 27 also has a guide edge so that the extruder head 23 can be guided to slide. A second support plate 271 is installed on the top of the second support rail 27. The second support plate 271 is used to support and install the second hydraulic rod 28. The second hydraulic rod 28 is installed on the second support plate 271. The second hydraulic rod 28 is used to push the push plate 281. The output end of the second hydraulic rod 28 is connected to the push plate 281. The push plate 281 is used to push the second hydraulic rod 28. The extruder head 23 on the second support rail 27 pushes the guide to slide, so that the extruder head 23 slides onto the first support rail 25, and the push plate 281 continues to squeeze and clamp the extruder head 23. Then the magnet rod 242 is inserted into the electromagnet 231 and magnetically adsorbed, and the push plate 281 is separated from the extruder head 23. The electromagnet 231 drives the extruder head 23 to pull back and insert it into the connecting head 21 and the limit block 22 for quick installation. A water pool 29 is placed on the side end of the base 1. The water pool 29 is set below the slide 26. The extruder head 23 falls into the water pool 29 for cooling. The extruder head 23 is fished out after cooling down.

[0028] The working principle of the utility model is as follows: the electromagnet 231 is energized to generate magnetism, the first hydraulic rod 241 pushes the magnet rod 242, so that the magnet rod 242 is inserted into the electromagnet 231 and magnetically adsorbed, and the magnet rod 242 continues to push, so that the extruder head 23 is separated from the connector 21 and the limit block 22, and guided to slide on the first support rail 25, so that the extruder head 23 is pushed onto the slide 26, and the extruder head 23 is guided to slide into the water pool 29 through the slide 26 and the limit plate 261. The water pool 29 is set below the slide 26, and the extruder head 23 falls into the water pool 29 for cooling. After cooling, the extruder 23 is fished out again. The second hydraulic rod 28 pushes the push plate 281, and the push plate 281 pushes the guide slide of the extruder head 23 to be installed on the second support rail 27, so that the extruder head 23 slides onto the first support rail 25. The push plate 281 continues to squeeze and clamp the extruder head 23. Then, the first hydraulic rod 241 drives the magnet rod 242 to insert into the electromagnet 231 and magnetically attract it. The push plate 281 is separated from the extruder head 23, and the electromagnet 231 drives the extruder head 23 to be pulled back and inserted into the connector 21 and the limit block 22 for rapid installation, which also prevents the extruder head 23 from being easily damaged by high temperature.
