Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Refer to Figures 1-4 As shown: An automatic feeding device for plastic granules includes a conveyor 1. A separation mechanism is provided on one side of the conveyor 1. The separation mechanism includes a screening hopper 4, a second conveyor 5, and a cleaning strip 16. The bottom of the screening hopper 4 is bolted to the first conveyor 1. A screening plate 11 is fixedly connected to the inner wall of the screening hopper 4. The bottom of the cleaning strip 16 is slidably connected to the screening plate 11. A vibrating motor 9 is installed on one side of the screening hopper 4, and a discharge port 12 is opened on the other side of the screening hopper 4. A guide plate 18 is provided on one side of the discharge port 12. The guide plate 18 is fixedly connected to the screening hopper 4, and the bottom of the guide plate 18 overlaps with the second conveyor 5. One side of the second conveyor 5 is connected to the first conveyor 1 by bolts. A rack guide table 13 is fixedly connected to the inner wall of the screening hopper 4. A slide table 14 is slidably connected to one side of the rack guide table 13. A connecting frame 17 is fixedly connected to one side of the slide table 14. The bottom of the connecting frame 17 is fixedly connected to the cleaning strip 16. A servo motor 15 is fixedly connected to one side of the slide table 14. A gear is fixedly connected to the output shaft of the servo motor 15. The gear meshes with the rack of the rack guide table 13.

[0024] A vibrating motor 9 installed on one side of the screening hopper 4 generates high-frequency vibration after being powered on and transmits it to the screening plate 11. After the plastic granules fall into the screening plate 11, they are classified by vibration. Vibrating screening removes excessively large impurities or classified granules, ensuring that the output granules have a uniform particle size and meet the requirements of subsequent production for particle specifications. The qualified plastic granules after screening are discharged from the discharge port 12 on the other side of the screening hopper 4 and guided by the guide plate 18 fixed on one side of the screening hopper 4, they fall precisely into the conveyor 2 5 that overlaps the bottom of the guide plate 18. The conveyor 1 and the conveyor 2 5 can transport granules of different volumes separately, avoiding mixing of granules of different volumes when feeding.

[0025] Example 2: Figure 1 and Figure 2 As shown, a sealing cover 2 is fitted into the inner wall of the screening hopper 4. Two magnetic adsorption plates 10 are fitted into the top of the sealing cover 2. The bottom of the magnetic adsorption plates 10 penetrates the sealing cover 2, and a feed inlet is provided between the two magnetic adsorption plates 10. Two adsorption hoods 6 are inserted through the inside of the sealing cover 2. The adsorption hoods 6 are fixedly connected to the sealing cover 2. An adsorption port is provided at the bottom of the adsorption hoods 6. A connecting pipe 7 is fixedly connected to the top of the adsorption hoods 6. One end of the connecting pipe 7 is fixedly connected to a filter box 3. The bottom of the filter box 3 is fixedly connected to the sealing cover 2. A filter screen is installed inside the filter box 3, and a blower 8 is fixedly connected to one side of the filter box 3.

[0026] The magnetic adsorption plate 10 is powered by an external controller, which can adsorb metal impurities in advance to avoid wear and tear on subsequent equipment. The sealing cover 2 reduces dust leakage. The adsorption cover 6 and the exhaust fan 8 form a negative pressure to collect dust. The filter box 3 intercepts dust, effectively reducing the pollution of workshop air by plastic dust. The sealing cover 2 is removable, which is convenient for disassembly and replacement, and also makes it easy to collect and remove the metal or magnetic impurities adsorbed at the bottom of the magnetic adsorption plate 10.

[0027] The operating method and working principle of this device are as follows: First, the plastic granules to be fed are fed into the screening hopper 4 through the feed inlet between the two magnetic adsorption plates 10. The granules fall above the screening plate 11. The vibrating motor 9 is started by an external controller. The vibrating motor 9 vibrates the screening plate 11 to screen the granules. Smaller granules pass through the screening plate 11 and fall onto the conveyor 1, which transports them. Larger granules remain above the screening plate 11. During the vibrating screening, the exhaust fan 8 adjusts the air pressure inside the filter box 3 and the connecting pipe 7 to ensure that the air pressure inside the filter box 3 and the connecting pipe 7 is controlled. Under negative pressure, the dust generated by vibration is adsorbed by the adsorption hood 6. The magnetic adsorption plate 10 can adsorb the magnetic material remaining above the screening plate 11. The servo motor 15 drives the gear to rotate, the slide table 14 moves along the rack guide table 13, and the connecting frame 17 drives the cleaning strip 16 to move on the top of the screening plate 11, discharging the residual material from the discharge port 12. After being guided by the guide plate 18, the material falls above the conveyor 5 and is fed by the conveyor 5. The sealing cover 2 is opened, and the inside of the rack guide table 13 can be cleaned regularly by using a fan or brush to reduce dust residue inside the rack guide table 13.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
