A vacuum pump 2 is fixedly connected to the end of the pipe on the outer wall of the silo 1, and the vacuum pump 2 is used to generate negative pressure or airflow in the silo 1, so that the raw materials are sucked into the silo 1 through the suction pipe 16, and the inner wall of the feeding port 18 is elastically connected to the limiting block 20 through a return spring b19, and one end of the return spring b19 is fixedly connected to the inner wall of the feeding port 18 The other end of the return spring b19 is fixedly connected to the back of the limit block 20, and the surface of the limit block 20 is set to an inclined surface. In the process of inserting the joint 17 into the feed port 18, the outer wall of the joint 17 squeezes the inclined surface of the limit block 20 to squeeze the return spring b19 to retract. At the same time, the elastic force generated by the deformation of the return spring b19 gives the limit block 20 a reverse thrust due to the deformation, prompting it to reset. A limit groove 22 is provided on the outer wall of the joint 17, and the outer wall of the limit block 20 is engaged with the inner wall of the limit groove 22. After the joint 17 is fully inserted into the feed port 18, the return spring b19 pushes the limit block 20 into the limit groove 22 and fixes it. A pull rod 21 is fixedly connected to the back of the limit block 20. Pulling the pull rod 21 outward can drive the limit block 20 to move outward together and be pulled out of the limit groove 22. At this time, the suction pipe 16 can be removed for cleaning and maintenance.

[0031] Reference Figure 1-Figure 2The bottom of the silo 1 is provided with a discharge port 3, and the outer wall of the discharge port 3 is detachably connected to a cover plate 4, and a motor 5 is welded on the back of the cover plate 4. A roller 6 is fixedly connected to the output shaft of the motor 5, and a baffle 7 is detachably connected to the outer wall of the roller 6. Starting the motor 5 can make the roller 6 drive the baffle 7 to rotate, so that the processed plastic raw materials can fall evenly. The outer wall of the roller 6 is fixedly connected to a plurality of groups of T-blocks 8, and the inner wall of the baffle 7 is provided with a T-slot 9. The outer wall of the T-block 8 is snapped into the inner wall of the T-slot 9. The outer wall of the roller 6 is provided with multiple groups of T-blocks 8. According to the number and spacing of the installed baffles 7, the discharge rate of the raw material can be more finely adjusted with the motor 5, while ensuring uniform discharge. The inner wall of the roller 6 is detachably connected to a limiting block 10. The limiting block 10 can ensure that the baffle 7 installed on the roller 6 will not gradually fall off with the rotation. The inner wall of the limiting block 10 is elastically connected to the pressing rod 11 through a reset spring a12. One end of the reset spring a12 is connected to the The inner end of the pressing rod 11 is fixedly connected, and the other end of the return spring a12 is fixedly connected to the inner wall of the drum 6. Pressing the pressing rod 11 inward can squeeze the return spring a12 to move inwardly of the drum 6. At the same time, the elastic force generated by the deformation of the return spring a12 gives the pressing rod 11 a reverse thrust to reset it. The inner wall of the pressing rod 11 is hinged with a bracket 13, and the end of the bracket 13 is hinged with a buckle assembly. The buckle assembly includes a block 14, and the bottom end of the block 14 is connected to the bracket 1 3 ends are hinged, the outer wall of the card block 14 is slidably connected to the inner wall of the limiting block 10, and pressing the pressing rod 11 inward can drive the angle of the bracket 13 to change, thereby driving the card block 14 to be retracted or unfolded along the inner wall of the limiting block 10. A card slot 15 is provided on the inner wall of the drum 6, and the outer wall of the card block 14 is engaged with the inner wall of the card slot 15. The card block 14 is inserted into the card slot 15 to fix the limiting block 10 on the drum 6, thereby supporting the connection part between the baffle 7 and the drum 6 to prevent it from falling off as the motor 5 rotates.

[0032] Working principle: Start the vacuum pump 2 to change the air pressure in the silo 1, so that the raw materials are sucked into the silo 1 through the suction pipe 16, and discharged from the discharge port 3 after processing. After the raw materials are processed, start the motor 5 to make the roller 6 drive the multiple sets of baffles 7 to rotate, so that the raw materials can be discharged evenly. In addition, the amount discharged from the discharge port 3 can be more accurately controlled by installing different numbers of baffles 7. At the same time, the speed of the motor 5 can be changed to adjust the discharge rate. When the baffle 7 needs to be disassembled or installed, press it inward. Press the pressing rod 11 to make the bracket 13 drive the clamping block 14 to retract. At this time, the limiting block 10 can be pulled out from the roller 6 to expose the disassembly and assembly part of the baffle 7. At this time, the number of baffles 7 can be adjusted. The inner wall of the suction pipe 16 will adhere to some raw materials after long-term use, causing congestion and affecting the suction effect. When replacement or maintenance is required, pull the two sets of pull rods 21 outward to release the engagement between the limiting block 20 and the limiting groove 22, and then the suction pipe 16 can be removed from the feed port 18 for easy cleaning and maintenance.
