The tops of the multiple telescopic columns 4 are fixedly connected to the same sealing ring 6, which performs a sealing function and seals the material. The tops of the multiple springs 5 ​​are fixedly connected to the inside of the sealing ring 6.

[0035] The filter barrel 2 has multiple grooves 7 inside, which are designed to restrict the movement direction of subsequent components. The sealing ring 6 is slidably connected to the outside of the grooves 7. A filter shaft 8 is slidably connected inside the filter barrel 2, which is designed as a direct filtration component. The function of the filter shaft 8 is to filter the material. The top of the sealing ring 6 is coupled to the bottom of the filter shaft 8. Multiple locking blocks 9 are fixedly connected to the outside of the filter shaft 8. The locking blocks 9 are designed to realize the extrusion and filtration operation of PET bottle flakes. The outside of the locking blocks 9 is slidably connected to the outside of the filter barrel 2 and is engaged with the outside of the grooves 7. A feed pipe 10 is fixedly connected to the outside of the filter barrel 2. The feed pipe 10 is designed as the inlet for the material entering the device. An opening and closing component for quantitative feeding is fixedly connected to the top of the feed pipe 10.

[0036] Reference Figures 3 to 5 The opening and closing assembly includes a feeding hopper 11, which is designed to receive PET bottle flakes. The feeding hopper 11 is externally fixedly connected to the inside of the feeding pipe 10. A cylinder 12 is fixedly connected inside the feeding pipe 10, which is designed as a power drive source. A push block 13 is fixedly connected to the drive end of the cylinder 12, which is designed to control the opening and closing state of the material in the feeding hopper 11. A rotating shaft 14 is rotatably connected inside the feeding hopper 11, which is designed as a key component connecting multiple parts and realizing the rotation function. A fan blade 15 is fixedly connected to the outside of the rotating shaft 14, which is designed to block or allow material to pass through. The fan blade 15 is slidably connected to the outside of the feeding hopper 11. A rotating head 16 is fixedly connected to the outside of the rotating shaft 14, which is designed to transmit rotational force. The rotating head 16 is externally coupled to the outside of the push block 13.

[0037] A fan blade 17 is rotatably connected to the outside of the rotating shaft 14. The fan blade 17 is designed to accurately realize the function of quantitative feeding.

[0038] Working principle: When multi-stage filtration of impurities in PET bottle flakes is required according to different production plans to improve the quality of extruded products, filter shafts 8 with different mesh sizes are replaced. The locking block 9 is slid into the filter barrel 2 along the slide groove 7 and rotated to engage the locking block 9. At this time, multiple telescopic columns 4 and springs 5 ​​are compressed. After the locking block 9 is engaged, the multiple springs 5 ​​release their elasticity to compress the sealing ring 6, making it seal and fit tightly with the filter shaft 8. This allows for quick replacement of filter shafts 8 with different mesh sizes according to production needs, while effectively preventing PET bottle flakes from leaking from the connection between the filter shaft 8 and the filter barrel 2 during the filtration process. This ensures the stable and efficient operation of the entire filtration system, thereby guaranteeing the high quality of the extruded products.

[0039] When production requires timed and quantitative material release according to different production plans, cylinder 12 is activated, and the drive end pushes the push block 13 to move, which in turn pushes the rotating head 16 and rotating head 18, thereby driving the rotating shaft 14 to rotate. This, in turn, controls the fan blade 15 to rotate inside the feed hopper 11, driving the fan blade 17 to rotate outside the rotating shaft 14. Controlling the fan blade 17 to rotate inside the feed hopper 11 allows the material inside the feed hopper 11 to be released in a timed and quantitative manner, thus meeting the strict requirements for timed and quantitative material supply during the production process, and ensuring the smooth operation of the entire production process to meet production needs.
