Description

Technical Field

[0001] This utility model relates to the field of plastic granule processing, and in particular to a feeding device for plastic granule processing. Background Technology

[0002] According to the patent document with publication number CN221793471U, the patent document describes a process where raw materials are transported on a conveyor. A cylinder drives a barrier frame to move downwards, which in turn moves a blocking vertical bar to block some of the raw materials on the conveyor. A drive motor drives an anti-blocking impeller to rotate, which in turn sends the raw materials that fall into the feeding box to the plastic processing machine. An ion fan generates ion air and introduces it into the feeding box from the air outlet to remove static electricity from the raw materials, while blowing the raw materials to the bottom of the feeding box.

[0003] The patent document states that during the conveyor transport of raw materials, some materials remain on the surface of the conveyor, resulting in material waste. Furthermore, the residual materials will mix into the next batch of raw materials, causing uneven color and composition of the plastic granules and affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for processing plastic granules in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A feeding device for processing plastic granules includes two conveyor frames, a plurality of conveyor rollers rotatably connected between the two conveyor frames, a conveyor belt covering the plurality of conveyor rollers, a feeding box fixed on one side of the two conveyor frames, and a cleaning mechanism located at the bottom of one side of the conveyor belt.

[0007] The cleaning mechanism includes a scraper, which is rotatably connected inside the feeding box. A rotating shaft is provided on one side of the scraper. Cams for striking the scraper are fixed at both ends of the rotating shaft inside the feeding box. First gears are fixed at both ends of the rotating shaft that pass through the feeding box. Second gears are meshed at the top of the two first gears. Two fixing plates are provided on the other side of the scraper. Springs are fixedly connected between the two fixing plates and the scraper.

[0008] Preferably, a material leveling frame is slidably connected between the two transmission frames. The material leveling frame is located at the top of the transmission belt, and a cylinder is fixed to the transmission frame located at the rear of the transmission belt. The telescopic end of the cylinder is fixedly connected to the material leveling frame.

[0009] Preferably, the material leveling rack consists of a sliding plate and several material leveling plates, with the material leveling plates fixed at equal intervals at the bottom of the sliding plate.

[0010] Preferably, the tip of the scraper contacts the bottom of the conveyor belt.

[0011] Preferably, the rotating shaft is rotatably connected inside the feeding box.

[0012] Preferably, two second gears are fixed at both ends of the transmission roller closest to the feeding box, and a motor is fixedly installed at the input end of the transmission roller closest to the feeding box.

[0013] Preferably, two fixing plates are fixed to the front and rear sides of the inside of the feeding box, respectively.

[0014] The beneficial effects compared with the existing technology are as follows: the two first gears rotate counterclockwise, driving the rotating shaft and the two cams to rotate counterclockwise. Then, the two cams strike the scraper to the other side, and the scraper rotates to the other side, compressing the two springs. As a result, the two springs react and extend, pushing the scraper to reset. This makes the scraper vibrate during the scraping of residual plastic particles on the conveyor belt. The scraper will not accumulate too much residual material and reduce the cleaning effect due to prolonged scraping and cleaning of the conveyor belt. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-7 As shown, a feeding device for processing plastic granules includes two transmission frames 1, a plurality of transmission rollers 2 rotatably connected between the two transmission frames 1, a transmission belt 3 covering the plurality of transmission rollers 2, a feeding box 4 fixed on one side of the two transmission frames 1, and a cleaning mechanism 5 located at the bottom of one side of the transmission belt 3.

[0028] In this embodiment: the cleaning mechanism 5 includes a scraper 501, which is rotatably connected inside the feeding box 4. The tip of the scraper 501 contacts the bottom of the conveyor belt 3. A rotating shaft 502 is provided on one side of the scraper 501, which is rotatably connected inside the feeding box 4. Cams 503 for striking the scraper 501 are fixed at both ends of the rotating shaft 502 inside the feeding box 4. First gears 504 are fixed at both ends of the rotating shaft 502 that protrude from the feeding box 4. Second gears 505 are meshed at the top of the two first gears 504. Two fixing plates 506 are provided on the other side of the scraper 501. Springs 507 are fixedly connected between the two fixing plates 506 and the scraper 501. The two second gears 505 are respectively fixed at both ends of the conveyor roller 2 closest to the feeding box 4. A motor is fixedly installed at the input end of the conveyor roller 2 of the material box 4. Two fixing plates 506 are fixed on the front and rear sides of the inside of the material box 4, respectively. The motor drives the conveyor roller 2 to rotate clockwise, which in turn drives the two second gears 505 to rotate. The two second gears 505 mesh with the two first gears 504, thereby driving the two first gears 504 to rotate counterclockwise. The counterclockwise rotation of the two first gears 504 drives the rotating shaft 502 and the two cams 503 to rotate counterclockwise. Then, the two cams 503 strike the scraper 501 on the other side. The scraper 501 rotates on the other side and compresses the two springs 507. The two springs 507 then extend in reaction and push the scraper 501 to reset, so that the scraper 501 vibrates during the scraping of the plastic particles remaining on the conveyor belt 3.

[0029] In this embodiment: a material leveling frame 6 is slidably connected between two transmission frames 1. The material leveling frame 6 is located at the top of the transmission belt 3. A cylinder 7 is fixed to the transmission frame 1 located behind the transmission belt 3. The telescopic end of the cylinder 7 is fixedly connected to the material leveling frame 6. The material leveling frame 6 consists of a sliding plate and several material leveling plates. The material leveling plates are fixed at equal distances at the bottom of the sliding plate. The transmission roller 2 closest to the feeding box 4 is driven by a motor to rotate, thereby driving the transmission belt 3 and the remaining transmission rollers 2 to rotate, thereby transporting the plastic granules. The sliding plate in the material leveling frame 6 is driven by the cylinder 7 to move back and forth along the front and rear sides, thereby driving the several material leveling plates to move on the top of the transmission belt 3, thereby evenly distributing the pile of plastic granules.

[0030] Working principle: Plastic granules are poured onto the top of the other side of the conveyor belt 3. The motor drives the conveyor roller 2 closest to the feeding box 4 to rotate, which in turn drives the conveyor belt 3 and the remaining conveyor rollers 2 to rotate, thereby transporting the plastic granules. The plastic granules move from the other side of the conveyor belt 3 to one side and finally fall into the feeding box 4. During this process, the cylinder 7 drives the sliding plate in the equalization rack 6 to move back and forth along the front and rear sides, which in turn drives several equalization plates to move on the top of the conveyor belt 3, thereby evenly dispersing the pile of plastic granules.

[0031] During the transport of plastic granules on conveyor belt 3, the motor drives the conveyor roller 2 to rotate clockwise, which in turn drives the two second gears 505 to rotate. The two second gears 505 mesh with the two first gears 504 respectively, thereby driving the two first gears 504 to rotate counterclockwise. The counterclockwise rotation of the two first gears 504 drives the rotating shaft 502 and the two cams 503 to rotate counterclockwise. Then, the two cams 503 strike the scraper 501 on the other side. The scraper 501 rotates on the other side and compresses the two springs 507. Thus, the two springs 507 react and extend to push the scraper 501 to reset. This causes the scraper 501 to vibrate during the scraping of residual plastic granules on conveyor belt 3, shaking off the remaining material at the contact position between the scraper 501 and the conveyor belt 3.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
