[0016] 1. By using the operating lever in conjunction with the guide bar to drive the limit block to move downward and squeeze the reset spring, the limit block is released from its restriction on the machine body shell, making it easier for the operator to pull the extruder head body to the left and move it along the first positioning block to the left to disengage it from the left side of the machine body shell. This makes it easier for the operator to replace the extruder head body and improves the efficiency of the device.

[0017] 2. By rotating the first limiting rod, the first limiting rod is released from its restriction on the first support frame and the positioning ring, making it easier for the operator to pull to the right to remove the first support frame and the extrusion rod for cleaning and maintenance. This prevents material residue inside the device from mixing with the material to be used next time, thereby improving the processing effect of the device.

[0018] 3. The second support frame is fixed in the middle of the extrusion head body by the second positioning block and the second limiting rod, so that the filter screen set inside the second support frame can filter and screen the material, preventing unmelted material from being squeezed outward through the extrusion head body, thus improving the processing quality of the device.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a PA66 material extruder that can avoid mixing of different materials, including: a base 1, and a machine body shell 2 disposed on the upper side of the base 1, an air inlet 3 disposed on the upper side of the machine body shell 2, and a heating chamber 4 opened at the lower end of the air inlet 3, and a feed inlet 5 disposed on the upper right side of the base 1, and further including:

[0027] A positioning ring 6 is installed on the right side of the outer casing 2. A first support frame 7 is provided inside the positioning ring 6, a first limiting rod 8 is provided on the outside of the first support frame 7, a drive motor 9 is provided on the right side of the first support frame 7, an extrusion rod 10 is connected to the left side of the first support frame 7, and a first sealing ring 11 is provided in the middle of the first support frame 7. A first positioning block 12 is provided on the upper left side of the outer casing 2, and a second sealing ring 13 is provided in the middle of the left side of the outer casing 2. An extrusion head body 14 is provided on the left side of the second sealing ring 13, and a limiting component 15 is provided at the lower end of the extrusion head body 14. A second support frame 16 is provided in the middle of the extrusion head body 14, and a filter screen 18 is provided inside the second support frame 16, thus constituting a complete PA66 material extruder.

[0028] like Figure 1 , Figure 2 and Figure 4As shown, the limiting assembly 15 includes a limiting block 1501 installed at the lower end of the extruder head body 14, a guide strip 1502 is provided on the outer side of the limiting block 1501, a return spring 1503 is provided on the lower side of the limiting block 1501, and an operating rod 1504 is provided on the inner side of the return spring 1503. The limiting block 1501 is engaged with the outer shell 2 of the machine body, and the limiting block 1501 and the guide strip 1502 are slidably disposed relative to each other. The first positioning block 12 is slidably disposed relative to the extruder head body 14, and the longitudinal section of the first positioning block 12 is a "T" shaped structure. A second sealing ring... The extruder body 13 is engaged with both the outer casing 2 and the extruder body 14. Before use, by pulling the operating lever 1504 downward, the operating lever 1504 causes the limiting block 1501 to move downward along the guide strip 1502 and press the reset spring 1503. At this time, the limiting block 1501 relaxes its restriction on the outer casing 2, making it easier for the operator to pull the extruder body 14 to the left. This causes the extruder body 14 to move to the left along the first positioning block 12 and disengage from the left side of the outer casing 2, making it easier for the operator to replace the extruder body 14 and improving the efficiency of the device.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the first limiting rod 8 is threadedly connected to the first support frame 7 and the positioning ring 6. The first limiting rod 8 is symmetrically arranged about the central axis of the first support frame 7. After the device is used, by rotating the first limiting rod 8, the first limiting rod 8 is relaxed from limiting the first support frame 7 and the positioning ring 6. This makes it easier for the operator to pull the first support frame 7 and the extrusion rod 10 to the right to remove them for cleaning and maintenance, preventing material residue inside the device from mixing with the material to be used next time, and improving the processing effect of the device.

[0030] like Figure 1 , Figure 3 and Figure 5 As shown, a second positioning block 17 is provided at the lower end of the second support frame 16, and a third sealing ring 19 is provided on the outer side of the second support frame 16.

The second limiting rod 20 is threadedly connected to both the second support frame 16 and the extruder head body 14. The second positioning block 17 and the third sealing ring 19 are engaged with the second support frame 16. During the use of the device, the second support frame 16 is installed inside the extruder head body 14 along the second positioning block 17. At the same time, the second limiting rod 20 is rotated, so that the second limiting rod 20 connects the second support frame 16 and the extruder head body 14 to limit the second support frame 16 to the middle of the extruder head body 14. The material is filtered and screened by the filter screen 18 provided inside the second support frame 16, preventing unmelted material from being extruded outward through the extruder head body 14, thereby improving the processing quality of the device.
