[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6 As shown, a feeding auxiliary device for a plastic mixer includes a feeding box 1, a feeding pipe 2 on the bottom surface of the feeding box 1, a filter cylinder 4 fixedly connected to the dust collection hood 3 extending into the dust collection hood 3, the filter cylinder 4 having open ends at both the top and bottom, a discharge hole that cooperates with the filter cylinder 4 at the lower end of the dust collection hood 3, a discharge hopper 8 fixedly connected to the lower end of the dust collection hood 3, and a discharge pipe fixedly connected to the lower end of the discharge hopper 8. The feeding box 1 contains raw material particles. When feeding is required, the raw material in the feeding box 1 is fed into the feeding pipe 2 by a pumping mechanism, and the raw material enters the filter cylinder 4 along with the feeding pipe 2.

[0025] A sealing block 7 is slidably inserted into the lower end of the filter cylinder 4. The sealing block 7 seals the bottom surface of the filter cylinder 4 to prevent material from being discharged before cleaning. A feeding boss 20 is fixedly connected to the upper end of the sealing block 7. The bottom surface of the dust collection hood 3 is provided with an opening and closing mechanism that drives the sealing block 7 to slide up and down. The opening and closing mechanism includes connecting pieces fixedly connected to both sides of the sealing block 7. Electric push rods 9 are fixedly connected to the bottom surface of the dust collection hood 3 on both sides. The electric push rods 9 on both sides are fixedly connected to the connecting pieces on both sides. When it is necessary to discharge raw materials, the electric push rods 9 are activated to push the sealing block 7 downward to extend out of the discharge hole, and the material in the filter cylinder 4 can be discharged from the discharge hole. The feeding boss 20 can effectively prevent raw materials from piling up on the feeding boss 20.

[0026] The upper end of the sealing block 7 is rotatably connected to an air jet pipe 10 located at the axis of the filter cylinder 4. The air jet pipe 10 has at least one air nozzle 11 on one side. The sealing block 7 has a control chamber 19. One end of the air jet pipe 10 extending into the control chamber 19 is rotatably connected to an air inlet pipe 12. The sealing block 7 is equipped with an air jet pump 14 communicating with the air inlet pipe 12. The lower end of the feeding pipe 2 is fixedly connected to a dust collection hood 3. The dust collection hood 3 has a dust discharge pipe 5 on one side. The end of the dust discharge pipe 5 is equipped with a detachable dust collection bag 6. The control chamber 19 is equipped with a rotating mechanism that drives the air jet pipe 10 to rotate. The rotating mechanism includes a driven gear ring 16 fixedly sleeved on the outer wall of the air jet pipe 10. The control chamber 19 is rotatably connected to a driving gear 17 that meshes with the driven gear ring 16. The control chamber 19 is fixedly connected to a motor 15 that drives the driving gear 17 to rotate.

[0027] When it is necessary to clean the raw materials inside the filter cylinder 4, the jet pump 14 is started to generate compressed gas. The gas is delivered to the jet pipe 10 through the air inlet pipe 12 and finally ejected at high speed from multiple jet nozzles 11 distributed on the side wall of the jet pipe 10, forming multiple strong airflows. Almost simultaneously, the motor 15 located in the control cavity 19 inside the sealing block 7 is started, driving the drive gear 17 to rotate. The drive gear 17 meshes with the driven gear ring 16 fixedly sleeved on the outer wall of the jet pipe 10, thereby driving the entire jet pipe 10 to rotate stably around its axis. The rotating jet nozzles 11 blow the airflow evenly to the entire inner wall surface of the filter cylinder 4. The powerful airflow can penetrate the mesh and blow the dust embedded in the mesh out in the opposite direction. The dust is collected by the dust collection bag 6. When the dust in the dust collection bag 6 accumulates to a certain amount, the operator can easily remove it from the end of the dust discharge pipe 5 for cleaning or replacement. Maintenance is very simple.

[0028] At least one stirring blade 13 is fixedly connected to the outer wall of the jet pipe 10. Each stirring blade 13 has a bristle 18 fixedly connected to its end. The stirring blade 13 and its bristle 18, which rotate together with the jet pipe 10, directly contact the inner wall of the filter cylinder 4. The bristle 18 can effectively scrape off stubborn impurities that are difficult to remove by airflow alone and adhere to the filter wall. The rotation of the stirring blade 13 also gently turns over the plastic particles inside the filter cylinder 4, exposing the dust wrapped inside the particle pile and carrying it away by the airflow, thus achieving deep and all-round dust removal.

[0029] In practical use, plastic granules fall from the feeding box 1 into the filter cylinder 4 through the feeding pipe 2. At this time, the opening and closing mechanism drives the sealing block 7 to the rising position, sealing the lower end of the filter cylinder 4. The granular raw material stays briefly in the cylinder, and the jet pump 14 is started. Compressed air enters the jet pipe 10 through the air inlet pipe 12 and is ejected at high speed from the jet nozzle 11. The fine dust mixed in is forced through the mesh of the filter cylinder 4 by gravity and subsequent airflow disturbance. Under the negative pressure in the dust collection hood 3, it is collected in the dust collection bag 6 at the end through the dust discharge pipe 5, realizing dust separation. At the same time, the motor 15 in the control chamber 19 is started. Through the meshing of the drive gear 17 and the driven gear ring 16, the jet pipe 10 and its stirring blades 13 and brush bristles 18 rotate together. The ejected airflow can blow off the dust clogging the mesh, while the rotating brush bristles 18 directly scrape the inner wall of the cylinder to remove the attached substances. The removed dust falls into the dust collection hood 3 and is collected. When cleaning is complete or when feeding is required, the opening and closing mechanism activates, the electric push rod 9 retracts, and the sealing block 7 moves downward, opening the discharge hole below the filter cylinder 4. Under the influence of gravity, the purified plastic granules are guided by the feeding boss 20, pass through the feeding hopper 8 at the lower end of the dust collection hood 3 and the discharge pipe, and finally enter the plastic mixer cleanly. After feeding is completed, the sealing block 7 can rise and close again, ready for the next round of feeding.
