[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: a feeding mechanism of a quantitative automatic packaging scale, including a hopper 1. An auxiliary component for removing residual materials is arranged inside the hopper 1. The auxiliary component includes an electromagnet 2 arranged on the inner wall of the outlet of the hopper 1. The electromagnet 2 can be controlled by a PLC controller to generate magnetic poles and adsorb to the magnetic block 301 on the outer wall of the chassis 3, so as to fix the chassis 3 at the outlet of the hopper 1. A chassis 3 and a support frame 4 are arranged on the inner wall of the hopper 1. The inner wall of the chassis 3 is of an inclined structure to facilitate the passage of materials. The support frame 4 is initially located above the materials in the hopper 1, so that the materials are between the support frame 4 and the chassis 3. A magnetic block 301 is arranged on the outer wall of the chassis 3. A cross plate 5 is arranged inside the support frame 4. Extension rods 501 are arranged at both ends of the cross plate 5. The extension rods 501 are used to connect the cross plate 5 and the support frame 4. The cross plate 5 and the support frame 4 can cooperate to surround and fit the inner wall of the hopper 1. And the extension rods 501 are slidably connected to the inside of the cross plate 5. When the support frame 4 slides up and down in the hopper 1, the width of the support frame 4 can be telescopically adjusted in cooperation with the inclined surface in the hopper 1. Scrapers 6 are arranged on the outer walls of the support frame 4, the cross plate 5 and the extension rods 501. The scrapers 6 surround the outer walls of the support frame 4 and the cross plate 5 to make them fit the wall of the hopper 1. When the support frame 4 moves up and down, the materials attached to the wall of the hopper 1 can be scraped off to prevent the materials from remaining in the hopper 1. A cavity 7 is arranged inside the support frame 4. A winding roller 701 is arranged inside the cavity 7. The winding roller 701 can be controlled by a PLC controller to rotate in the cavity 7, and wind or release the connecting rope 8 to pull the support frame 4 to move in the hopper 1 and limit the moving range of the support frame 4. A connecting rope 8 is arranged outside the winding roller 701 for connecting the support frame 4 and the chassis 3.
[0019] When conveying materials with high viscosity or high water content, due to the high viscosity of the materials, they will adhere to the wall of the hopper 1 when contacting the inner wall of the hopper 1, so that they cannot be completely discharged from the hopper 1 during feeding, thus affecting the accurate weighing and stable operation of the quantitative automatic packaging scale, and will cause pollution to the subsequent materials and affect the quality of the materials.
[0020] In this embodiment, all electrical components are controlled by a conventional controller.
[0021] For the embodiment, please refer to Figures 1-4, the electromagnet 2 is inlaid and connected to the inner wall at the outlet of the hopper 1. The chassis 3 is located at the outlet of the hopper 1. The magnetic block 301 is connected to the outer wall of the chassis 3. The electromagnet 2 is magnetically connected to the magnetic block 301. The support frame 4 is located inside the hopper 1 and is slidably connected to the inner wall of the hopper 1 through a slide rail. One end of the extension rod 501 is located inside the cross plate 5, and the other end extends to the outside and is connected to the inner wall of the support frame 4 through a bolt. The outer walls of the support frame 4, the cross plate 5, and the extension rod 501 are all in contact with the inner wall of the hopper 1, and the scraper 6 is connected to its outer wall through a bolt. The cavity 7 is located at the bottom of the support frame 4. The winding roller 701 is located inside the cavity 7 and is rotatably connected to the inner wall of the cavity 7 through a connecting shaft. One end of the connecting rope 8 is wound around the outside of the winding roller 701, and the other end passes through the cavity 7 and extends to the outside to be connected to the chassis 3. The material in the hopper 1 is located between the chassis 3 and the support frame 4. An infrared sensor is installed on the inner wall of the support frame 4, and the infrared sensor is electrically connected to the winding roller 701. During use, first, the support frame 4 is controlled by the PLC controller to move to the uppermost position inside the hopper 1. Then, the material is loaded into the hopper 1 and loaded into the area below the support frame 4. Then, the material is guided into the corresponding partition wall by the sensor inside the hopper 1, and the items are accurately separated and sent to the corresponding weighing areas respectively. When the material is discharged from the hopper 1, the height of the material is sensed by the infrared sensor on the inner wall of the support frame 4, and the PLC controller controls the winding roller 701 to rotate inside the cavity 7 to wind up the connecting rope 8, thereby pulling the support frame 4 to move downward in the hopper 1 to match the height of the material. While the support frame 4 is moving, the scraper 6 on the outer walls of the support frame 4 and the transverse frame (i.e., the cross plate 5 and the extension rod 501) abuts against the inner wall of the hopper 1 to scrape off the attached material, cleaning the inner wall of the hopper 1 to avoid material residue.
