[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Example 1 Please refer to Figures 1-11 As shown, a continuous plastic granule processing system includes a machine body 1. An annular groove 106 is formed through the middle of the top of the machine body 1. A sleeve 102 is fixedly connected to the top of the machine body 1. The bottom center of the sleeve 102 is concentric with the center of the annular groove 106. An extrusion device 101 is installed inside the sleeve 102. Two sets of cylinders 103 are fixedly installed at the top of the sleeve 102. The output end of the cylinders 103 is fixedly connected to a clamping block 104. The two sets of clamping blocks 104 are used to fix a ring body 105. Two sets of extrusion dies with different apertures are provided in the upper and lower parts of the ring body 105. The extrusion die sets cooperate with the extrusion device 101 to extrude plastic granules. A feeding mechanism 2 for cutting and feeding plastic granules is installed inside the sleeve 102. A shielding mechanism 3 is provided at the bottom of the machine body 1. A lifting mechanism 4 is installed on the rear side of the top of the machine body 1. An external cleaning mechanism 5 and a multi-functional mechanism 6 are respectively provided on the left and right sides of the sleeve 102.

[0020] Example 2 Please refer to Figure 3 and Figure 4 As shown, the feeding mechanism 2 includes a first rotating gear ring 201 rotatably connected to the inner wall of the sleeve 102. A cutter 204 is fixedly connected to the bottom of the first rotating gear ring 201. A first drive motor 202 is also fixedly connected to the inner wall of the sleeve 102. The output end of the first drive motor 202 is fixedly connected to a first drive gear 203. The first drive gear 203 meshes with the first rotating gear ring 201.

[0021] Please refer to Figure 1 , Figure 2 and Figure 4As shown, the two side walls of the cutter 204 are respectively attached to the inner wall of the sleeve 102 and the outer wall of the ring 105. The height of the cutter 204 is adapted to the height of a set of extrusion dies. The top of the machine body 1 is provided with a discharge trough 107, and a collection box 108 is provided below the discharge trough 107.

[0022] Those skilled in the art will understand that the first drive gear 203 is driven to rotate by the output end of the first drive motor 202, causing the first rotating gear ring 201 to rotate. Consequently, the cutter 204 connected to its bottom rotates around the center of the first rotating gear ring 201. When the extrusion device 101 is working, plastic granules are extruded from the extrusion hole group. The cutter 204 is in contact with the outer wall of the ring body 105. Thus, while rotating, the plastic granules are cut, and the outer wall of the ring body 105 is cleaned and scraped. The cut plastic granules can be rotated to the discharge trough 107 and fall into the collection box 108 for collection.

[0023] Example 3 Please refer to Figure 2 As shown, the shielding mechanism 3 includes a frame 301, a first lead screw 302, and a first guide rod 303. The frame 301 is fixedly installed at the bottom of the machine body 1. The first lead screw 302 is rotatably connected to the inside of the frame 301. The first guide rod 303 is fixedly connected to the inside of the frame 301. A shielding ring 305 is threadedly connected to the outer surface of the first lead screw 302. The shielding ring 305 is slidably connected to the outer wall of the first guide rod 303. A first stepper motor 304 is also fixedly installed at the top of the machine body 1. The top of the first lead screw 302 is fixedly connected to the output end of the first stepper motor 304, and the shielding ring 305 is slidably connected to the inside of the annular groove 106.

[0024] Those skilled in the art will understand that the output end of the first stepper motor 304 drives the first lead screw 302 to rotate, causing the shielding ring 305 to move up and down along the outer wall of the first guide rod 303. During normal extrusion of plastic granules, the top of the shielding ring 305 is flush with the top of the machine body 1.

[0025] Example 4 Please refer to Figure 1 and Figure 5As shown, the lifting mechanism 4 includes a first fixed frame 401 fixedly connected to the rear side of the top of the body 1. A second lead screw 402 is rotatably connected inside the first fixed frame 401. A cylinder 405 is threadedly connected to the outer wall of the second lead screw 402. The cylinder 405 is slidably connected to the outer surface of the second guide rod 403. The second guide rod 403 is welded inside the first fixed frame 401. The top of the second lead screw 402 is fixedly connected to the output end of the second stepper motor 404. The second stepper motor 404 is located on the top of the first fixed frame 401. An electric cover plate 406 is also provided on the top of the cylinder 405.

[0026] Please refer to Figure 1 and Figure 4 As shown, a circular groove is provided through the middle of the top end of the sleeve 102. The diameter of the circular groove is the same as the outer diameter of the ring body 105. The outer diameter of the ring body 105 is the same as the outer diameter of the shielding ring 305. The outer diameter of the ring-shaped part at the bottom of the cylinder 405 is the same as the inner diameter of the ring body 105.

[0027] Those skilled in the art will understand that the output of the second stepper motor 404 drives the second lead screw 402 to rotate, causing the cylinder 405 to reciprocate up and down along the outer surface of the second guide rod 403. During normal operation of the plastic granule extrusion process, the cylinder 405 descends, causing the ring-shaped component at the bottom of the cylinder 405 to be located inside the ring 105 and cover the two sets of extrusion holes on the ring 105. The electric cover plate 406 automatically rotates and opens, exposing the top opening of the cylinder 405. The external raw material feeding machine pours the raw material for producing plastic granules from the top opening of the cylinder 405, allowing the raw material to directly enter the interior of the ring 105. Since the ring-shaped component at the bottom of the cylinder 405 covers the two sets of extrusion holes, the raw material will not flow out through the extrusion holes during the falling process, avoiding the raw material being exposed directly without being extruded, thus avoiding waste of raw material.

[0028] Example 5 Please refer to Figure 6As shown, the external cleaning mechanism 5 includes a second fixed frame 501 and a first movable frame 505. The second fixed frame 501 is fixedly installed on the top left side of the machine body 1. A third guide rod 503 is fixedly connected inside the second fixed frame 501. The first movable frame 505 is slidably connected to the outer wall of the third guide rod 503. A third lead screw 502 is also rotatably connected inside the second fixed frame 501. The first movable frame 505 is threadedly connected to the third lead screw 502. A third stepper motor 504 for driving the third lead screw 502 to rotate is provided on the outer side of the second fixed frame 501. A fourth lead screw 506 is rotatably connected inside the first movable frame 505. A lifting plate 509 is threadedly connected to the fourth lead screw 506. The lifting plate 509 is slidably connected to the outer wall of the fourth guide rod 507. The fourth guide rod 507 is fixedly installed inside the first movable frame 505. A fourth stepper motor 508 for driving the fourth lead screw 506 to rotate is also installed on the top of the first movable frame 505.

[0029] Please refer to Figure 6 and Figure 7 As shown, a second rotating gear ring 510 is rotatably connected inside the lifting plate 509. A blower 513 is fixedly installed at the bottom of the second rotating gear ring 510. A second drive motor 511 is fixedly connected to the top of the lifting plate 509. A second drive gear 512 is fixedly installed at the output end of the second drive motor 511. The second drive gear 512 meshes with the second rotating gear ring 510.

[0030] Those skilled in the art will understand that the output of the third stepper motor 504 drives the third lead screw 502 to rotate, causing the first moving frame 505 to reciprocate horizontally along the outer wall of the third guide rod 503, thereby driving the lifting plate 509 to reciprocate horizontally; the output of the fourth stepper motor 508 drives the fourth lead screw 506 to rotate, thereby driving the lifting plate 509 to reciprocate up and down along the outer wall of the fourth guide rod 507; and the output of the second drive motor 511 drives the second drive gear 512 to rotate, causing the second rotating gear ring 510 to rotate, which in turn drives the blower 513 connected to its bottom to rotate around the center of the second rotating gear ring 510.

[0031] Example 6 Please refer to Figure 8 and Figure 9As shown, the multifunctional mechanism 6 includes a third fixed frame 601 fixedly installed on the top right side of the body 1. A fifth lead screw 602 is rotatably connected inside the third fixed frame 601. A second movable frame 605 is threadedly connected to the fifth lead screw 602. The second movable frame 605 is slidably connected to a fifth guide rod 603. The fifth guide rod 603 is welded inside the third fixed frame 601. The outer end of the fifth lead screw 602 is fixedly connected to the output end of a fifth stepper motor 604. The fifth stepper motor 604 is installed on the outside of the third fixed frame 601. A sixth lead screw 606 is rotatably connected inside the second movable frame 605. A sixth stepper motor 608 that drives the sixth lead screw 606 to rotate is installed on the outer wall of the second movable frame 605. A sixth guide rod 607 is also fixedly connected inside the second movable frame 605. An L-shaped part 609 and a third movable frame 612 are slidably connected to the sixth guide rod 607. The L-shaped part 609 and the third movable frame 612 are threadedly connected to the sixth lead screw 606.

[0032] Please refer to Figure 9 , Figure 10 and Figure 11 As shown, a first electric push rod 610 is fixedly connected to the top of the horizontal plate of the L-shaped part 609. The output end of the first electric push rod 610 is fixedly connected to the cleaning ring 611. A seventh lead screw 613 is rotatably connected inside the third moving frame 612. A lifting frame 616 is threadedly connected to the outer wall of the seventh lead screw 613. The lifting frame 616 is slidably connected to the seventh guide rod 614. The seventh guide rod 614 is welded inside the third moving frame 612. A seventh stepper motor 615 is provided at the top of the third moving frame 612. The seventh stepper motor 615 outputs... The end extends into the third moving frame 612 and is fixedly connected to the top of the seventh lead screw 613. The inner sides of the lifting frame 616 are rotatably connected to the second electric push rods 617. The output ends of the two sets of second electric push rods 617 are equipped with clamping parts 618. The outer side of the lifting frame 616 is provided with a third drive motor 619. The output end of the third drive motor 619 is fixedly connected to the third drive gear 620. The outer wall of one set of second electric push rods 617 is provided with a driven gear 621 that meshes with the third drive gear 620.

[0033] Those skilled in the art will understand that by driving the fifth lead screw 602 to rotate through the output end of the fifth stepper motor 604, the second moving frame 605 moves back and forth along the outer wall of the fifth guide rod 603, and the L-shaped part 609 and the third moving frame 612 move back and forth horizontally, thereby driving the cleaning ring 611 and the lifting frame 616 to move back and forth horizontally. The output of the sixth stepper motor 608 drives the sixth lead screw 606 to rotate, causing the L-shaped part 609 and the third moving frame 612 to reciprocate back and forth in the longitudinal direction, thereby realizing the reciprocating back and forth movement of the cleaning ring 611 and the lifting frame 616 in the longitudinal direction. By controlling the extension or retraction of the output end of the first electric push rod 610, the cleaning ring 611 is driven to move downward or upward; and by driving the output end of the seventh stepper motor 615 to rotate, the lifting frame 616 moves up and down along the outer wall of the seventh guide rod 614.

[0034] To clearly describe the working principle of this invention, we will use... Figure 1 This is explained from a directional perspective, which refers to the "up, down, left, right, front, and back" as mentioned below, specifically as follows: S1. Place the ring body 105 inside the sleeve 102, with the set of extrusion holes on the ring body 105 facing downwards. Extend the output ends of the two sets of cylinders 103 to bring the two sets of clamping blocks 104 closer together, thus clamping and fixing the ring body 105. The output end of the second stepper motor 404 drives the second lead screw 402 to rotate, causing the cylinder 405 to descend, so that the ring-shaped component at the bottom of the cylinder 405 is located inside the ring body 105, covering the ring body 105. The two sets of extrusion holes control the electric cover plate 406 to automatically rotate and open, so that the top opening of the cylinder 405 is exposed. The external raw material feeding machine pours the raw material for producing plastic granules into the top opening of the cylinder 405. When the electric cover plate 406 is closed, the raw material directly enters the interior of the ring body 105. Since the ring-shaped part at the bottom of the cylinder 405 covers the two sets of extrusion holes, the raw material will not flow out through the extrusion holes during the falling process, thus avoiding the raw material being exposed directly without being extruded, and thus avoiding the waste of raw material. S2. The output end of the second stepper motor 404 is driven to rotate in the reverse direction again, causing the cylinder 405 to rise. This ensures that the ring-shaped part at the bottom of the cylinder 405 only covers the set of extrusion holes located in the upper part of the cylinder 105. During the extrusion process, the raw material is "stirred" inside the cylinder 105 under the action of the extrusion device 101. This prevents the raw material from flowing out of the set of extrusion holes located in the upper part, further avoiding waste of raw material. Then, the extrusion device 101 is started to work, extruding the raw material from the set of extrusion holes in the lower part. The extrusion process involves the first drive motor 202 driving the first drive gear 203 to rotate, causing the first rotating gear ring 201 to rotate. Consequently, the cutter 204 connected to its bottom rotates around the center of the first rotating gear ring 201. The cutter 204 is in contact with the outer wall of the ring body 105, so that while the plastic particles are being cut during rotation, the outer wall of the ring body 105 can also be cleaned and scraped. The cut plastic particles can be rotated to the discharge chute 107 and fall into the collection box 108 for collection. S3. When the material inside the ring 105 is not completely extruded and it is necessary to replace the extrusion hole group located in the upper part for extrusion, the two sets of clamping blocks 104 move away from each other, releasing the clamping and fixing of the ring 105. The output end of the first stepper motor 304 drives the first lead screw 302 to rotate, causing the shielding ring 305 to move upward along the outer wall of the first guide rod 303, thereby driving the ring 105 to move upward as well. However, the bottom of the ring 105 is still located in the circular groove opened in the middle of the top of the sleeve 102. Under the cooperation of the output ends of the third stepper motor 504 and the fourth stepper motor 508, the blower 513 is made to fit against the outer wall of the ejected ring 105, and through the second drive motor 5 The output end of 11 drives the second drive gear 512 to rotate, causing the second rotating gear ring 510 to rotate. This causes the blower 513 connected to its bottom to rotate around the center of the second rotating gear ring 510, thereby blowing the material remaining in the lower part of the extrusion hole group into the interior of the shielding ring 305. This is to prevent the material remaining in the extrusion hole group from flowing into the external environment when the ring body 105 is rotated later, further avoiding material waste. Also, due to the presence of the shielding ring 305, the material is prevented from scattering, keeping the material in the interior area of ​​the ring body 105. Furthermore, the outer wall of the ring body 105 does not need to be cleaned after being cleaned and scraped by the cutter 204. S4. The output end of the sixth stepper motor 608 drives the sixth lead screw 606 to rotate, so that the L-shaped part 609 is located in the longitudinal middle of the machine body 1. The output end of the fifth stepper motor 604 drives the fifth lead screw 602 to rotate, so that the L-shaped part 609 moves towards the ring body 105, causing the cleaning ring 611 to be located directly above the ring body 105. At this time, the center of the cleaning ring 611 and the center of the ring body 105 are on the same vertical line. Then, the output end of the first electric push rod 610 is controlled to extend, causing the cleaning ring 611 to move downward, scraping the inner wall of the ring body 105 downward, and sweeping the raw material on the inner wall into the interior of the shielding ring 305. S5 and L-shaped part 609 are reset, and the output end of the sixth stepper motor 608 drives the sixth lead screw 606 to rotate again, so that the third moving frame 612 is located in the longitudinal middle of the machine body 1. Under the action of the output end of the seventh stepper motor 615, the lifting frame 616 is driven to move downward, so that the lifting frame 616 is located in the middle position of the ring body 105. The output ends of the two sets of second electric push rods 617 are controlled to extend, so that the two sets of clamping parts 618 move closer to each other to clamp the middle position of the ring body 105.
