Specific embodiments

[0023] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of this application are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. For the embodiments of this application described here, based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0024] Referring to Figures 1 - 5 , a feeding device of a rubber extruder includes a barrel body 1. The barrel body 1 has an open structure at one end. A feeding pipe 20 is welded at a position near the end of the top of the barrel body 1. Rubber is added into the barrel body 1 through the feeding pipe 20. A blanking pipe 8 is welded at a position far from the feeding pipe 20 at the bottom of the barrel body 1. One end of the barrel body 1 where it is open is clamped with a cover plate 4. A locking assembly is provided on one side of the cover plate 4 to detachably connect the cover plate 4 to the barrel body 1. A connecting plate 21 is welded inside the barrel body 1 near the cover plate 4. One side of the connecting plate 21 is rotatably connected with a screw rod 10. An extrusion plate 9 that fits against the inner wall of the barrel body 1 is threadedly connected to the circumferential outer wall of the screw rod 10. A motor is fixed to one side of the barrel body 1 by bolts. One end of the output shaft of the motor passes through the barrel body 1 and is fixed to the screw rod 10. A guiding component for horizontally moving the extrusion plate 9 is provided between the connecting plate 21 and the barrel body 1. A scraping component is provided inside the blanking pipe 8 to clean the inside of the blanking pipe 8. The motor drives the screw rod 10 to rotate. The screw rod 10 drives the extrusion plate 9 to horizontally move under the action of the guiding component through the threaded engagement with the extrusion plate 9, extruding the rubber in the barrel body 1 out of the barrel body 1 through the blanking pipe 8 to extrude and feed the rubber in the barrel body 1. During the movement of the extrusion plate 9, since the extrusion plate 9 fits against the inner wall of the barrel body 1, the extrusion plate 9 will scrape and clean the rubber adhered to the inner wall of the barrel body 1, thereby preventing rubber from adhering to the inner wall of the barrel body 1, avoiding waste of rubber, and improving the use effect of the feeding device.

[0025] In the present utility model, the guiding components are two guiding rods 11. Both of the two guiding rods 11 are welded between the connecting plate 21 and the barrel body 1. Both of the two guiding rods 11 pass through the pressing plate 9. The guiding rods 11 play a guiding role on the pressing plate 9, enabling the pressing plate 9 to move horizontally along the guiding rods 11 during the movement process. The locking assembly includes a fixing plate 5. The fixing plate 5 is welded to one side of the cover plate 4. A rotating hole is provided on one side of the fixing plate 5. A bidirectional threaded rod 6 is rotatably connected in the rotating hole. Two sliding plates 7 are threadedly connected to the circumferential outer wall of the bidirectional threaded rod 6. The two sliding plates 7 are respectively located on both sides of the barrel body 1. Sockets 3 are provided on one side of each of the two sliding plates 7. Two inserting rods 2 are symmetrically welded to the circumferential outer wall of the barrel body 1 near the cover plate 4, and the inserting rods 2 pass through the sockets 3. Fixing columns 14 are welded to both sides of the fixing plate 5. The two fixing columns 14 respectively pass through the two sliding plates 7 to enable the sliding plates 7 to move horizontally. By rotating the bidirectional threaded rod 6, the bidirectional threaded rod 6 will drive the two sliding plates 7 to move in opposite directions along the fixing columns 14 through the threaded engagement with the two sliding plates 7, so that the inserting rods 2 are disengaged from the sockets 3 on the sliding plates 7. At this time, the cover plate 4 can be disassembled to clean the rubber adhered to the cover plate 4, which is convenient for cleaning the materials adhered to the cover plate 4;

[0026] The scraping assembly includes two sliding grooves 13. The two sliding grooves 13 are symmetrically provided on the circumferential inner wall of the blanking pipe 8. A scraping ring 12 that fits the inner wall of the blanking pipe 8 is slidably connected in the two sliding grooves 13. Pulling springs 19 are welded to the tops of the two sliding grooves 13, and the pulling springs 19 are fixed to the scraping ring 12. Two pulling ropes 18 extending out of the blanking pipe 8 are adhered to the bottom of the scraping ring 12. The bottoms of the two pulling ropes 18 are adhered to a mounting plate 17. By pulling the pulling ropes 18 through the mounting plate 17, the pulling ropes 18 will pull the scraping ring 12 to move downward along the sliding grooves 13, so that the scraping ring 12 scrapes and cleans the rubber adhered to the inner wall of the blanking pipe 8, avoiding the blockage of the blanking pipe 8 caused by the rubber adhering to the inner wall of the blanking pipe 8. A first magnetic block 16 is adhered to one side of the mounting plate 17. A second magnetic block 22 is adhered to the outer wall of the blanking pipe 8 near the bottom on one side, and the first magnetic block 16 and the second magnetic block 22 can be adsorbed. During the blanking process through the blanking pipe 8, the first magnetic block 16 on the mounting plate 17 and the second magnetic block 22 can be adsorbed, thereby avoiding the influence of the mounting plate 17 on the rubber blanking.

[0027] Working principle: When in use, add rubber into the barrel body 1 through the feeding pipe 20, and then drive the lead screw 10 to rotate through the motor. The lead screw 10 drives the extrusion plate 9 to move horizontally along the guide rod 11 through the thread engagement with the extrusion plate 9, so as to extrude the rubber in the barrel body 1 out of the barrel body 1 through the blanking pipe 8 for extrusion and blanking of the rubber in the barrel body 1. During the movement of the extrusion plate 9, since the extrusion plate 9 is in contact with the inner wall of the barrel body 1, the extrusion plate 9 will scrape and clean the rubber adhered to the inner wall of the barrel body 1, thereby preventing the rubber from adhering to the inner wall of the barrel body 1, avoiding waste of rubber, and improving the use effect of the feeding device. After use, rotate the bidirectional threaded rod 6. The bidirectional threaded rod 6 drives the two slide plates 7 to move in opposite directions along the fixed column 14 through the thread engagement with the two slide plates 7, so that the insertion rod 2 is disengaged from the socket 3 on the slide plate 7. At this time, the cover plate 4 can be disassembled to clean the rubber adhered to the cover plate 4, which is convenient for cleaning the material adhered to the cover plate 4.

[0028] The present utility model has been described through the above embodiments. Those skilled in the art can understand that the present utility model is not limited to the above embodiments, and more modifications can be made according to the teachings of the present utility model. These modifications all fall within the scope of protection required by the present utility model. The scope of protection of the present utility model is defined by the appended claims and their equivalent scope.
