[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 - Appendix Figure 4 A plastic production feeding device includes a mounting frame 1 and a screening mechanism 3 located on its right side. A quantitative feeding mechanism 4 is located below the screening mechanism 3. The screening mechanism 3 includes a material box 301, a servo motor 307, and a sliding frame 309. A screening plate 302 is snapped into the inside of the material box 301. A guide pipe 303 is fixedly installed on the right side of the material box 301. The material box 301 is connected to a feeding channel 306 through four sets of springs 305. A force plate 304 is fixedly installed on the upper surface of the material box 301 near the left side. A half gear ring 308 is fixedly installed on the output shaft of the servo motor 307. A vibrating column 310 is connected to the sliding frame 309 through a rack plate 311.

[0016] Limiting plates 2 are fixedly installed on both the front and back sides of the upper end of the mounting frame 1, and the limiting plates 2 abut against the front and back sides of the material box 301.

[0017] The limiting plates 2 fixedly installed on both sides of the upper end of the mounting frame 1 abut against the front and back sides of the material box 301, which plays a limiting and supporting role for the material box 301, effectively preventing the material box 301 from shifting or shaking during vibration, ensuring the stability of the screening mechanism 3, and thus ensuring the reliable operation of the entire feeding device, reducing the probability of wear and failure of parts caused by equipment shaking.

[0018] The upper ends of the four sets of springs 305 are fixedly installed at the four corners of the lower end of the material box 301, and the lower ends of the four sets of springs 305 are fixedly installed at the four corners of the upper end of the material discharge channel 306.

[0019] The material box 301 is connected to the feeding channel 306 by four sets of springs 305. This structural design can buffer the vibration of the material box 301 and reduce the impact of vibration on the feeding channel 306 and other components.

[0020] The servo motor 307 is fixedly installed on the upper end of the mounting bracket 1 near the front position. The sliding bracket 309 is fixedly installed on the upper end of the mounting bracket 1 near the right side position. The rack plate 311 is slidably connected inside the sliding bracket 309. The side of the vibration column 310 is fixedly installed on the side of the rack plate 311. The tooth groove of the rack plate 311 meshes with the half gear ring 308. The vibration column 310 is located directly above the force plate 304.

[0021] The transmission mechanism, consisting of servo motor 307, half gear ring 308, rack plate 311 and vibrating column 310, can accurately convert the rotational motion of servo motor 307 into the linear reciprocating motion of vibrating column 310 through precise gear meshing transmission. This ensures that the frequency and force of the vibration column 310 striking the force plate 304 are stable and controllable, thereby achieving stable and efficient vibrating screening of material box 301 and improving the consistency and reliability of screening effect.

[0022] Specifically, the screening plate 302 inside the material bin 301 can screen plastic raw materials, separate particles that meet production requirements, remove impurities and unqualified materials, and ensure the quality of raw materials entering subsequent production stages. At the same time, the servo motor 307 drives the half gear ring 308 to rotate, meshing with the rack plate 311, driving the vibrating column 310 to move up and down reciprocally, periodically striking the force plate 304, causing the material bin 301 to vibrate. This vibration can effectively prevent the screening plate 302 from clogging, improve screening efficiency, make the screening process smoother, and ensure efficient processing of raw materials.

[0023] Please see the appendix Figure 1 Appendix Figure 5 and attached Figure 6 The quantitative feeding mechanism 4 includes a support plate 401, which is fixedly installed on the right side of the mounting frame 1. A feeding port 407 is passed through the surface of the support plate 401 near the front. An mounting block 402 is fixedly installed on the back of the support plate 401. An electric telescopic rod 403 is fixedly installed on the front of the mounting block 402. A quantitative frame 404 is fixedly installed at the output end of the electric telescopic rod 403. The upper end of the quantitative frame 404 abuts against the lower end of the feeding channel 306.

[0024] The upper end of the quantitative frame 404 is tightly abutted against the lower end of the feeding channel 306. This structural design ensures the stable transmission of raw materials from the screening mechanism 3 to the quantitative feeding mechanism 4, avoiding raw material leakage or blockage at the connection point, and ensuring the continuity of the feeding process. The stable support structure composed of components such as the support plate 401 and the mounting block 402 provides a reliable installation foundation for the quantitative feeding mechanism 4, ensuring the stability of components such as the electric telescopic rod 403 and the quantitative frame 404 during operation.

[0025] The quantitative frame 404 is movably connected to a flap 406 via a hinge 405, and the flap 406 abuts against the surface of the support plate 401.

[0026] The metering frame 404 is movably connected to the flap 406 via the hinge 405. When feeding is not required, the flap 406 can abut against the surface of the support plate 401 to close the discharge port 407, preventing the raw material from accidentally spilling or flowing out prematurely. When feeding is required, the flap 406 can be opened flexibly to ensure a smooth feeding process, realize flexible control of the feeding process, and improve the convenience and safety of equipment operation.

[0027] Specifically, the plastic raw materials after screening are all of similar size, so the amount filled by the quantitative frame 404 is constant each time. The extension and retraction of the electric telescopic rod 403, together with the opening and closing of the flap 406, transports the quantitative raw materials to the processing area, improving the efficiency of material feeding.

[0028] Working principle of this utility model: This utility model is a plastic production feeding device. Plastic raw materials are conveyed to the material box 301 through external feeding equipment, and the material falls onto the screening plate 302 for preliminary screening. The servo motor 307 is started, and its output shaft drives the half-gear ring 308 to rotate. The half-gear ring 308 meshes with the tooth groove of the rack plate 311, driving the rack plate 311 to reciprocate up and down within the sliding frame 309. The rack plate 311 drives the vibrating column 310 to periodically impact the force plate 304, causing the material box 301 to vibrate. The vibration is transmitted to the discharge channel 306 through four sets of springs 305, which also act as buffers to avoid rigid impact. The raw material on the screening plate 302 is screened under the action of vibration. Qualified particles fall through the screening plate 302 into the discharge channel 306, while impurities and large particles are discharged through the guide pipe 303. The limiting plate 2 restricts the lateral displacement of the material box 301 to ensure the stability of the vibration process. The screened raw materials fall into the metering frame 404 through the feeding channel 306. The electric telescopic rod 403 is manually extended, moving the metering frame 404. When the metering frame 404 moves above the feeding port 407, the flap 406 flips around the hinge 405 under gravity or external force, opening the bottom of the metering frame 404. The raw materials inside the metering frame 404 then fall precisely into downstream processing equipment such as injection molding machines or extruders through the feeding port 407. The electric telescopic rod 403 retracts again, causing the metering frame 404 to return to its original position, and the flap 406 re-adhere to the surface of the support plate 401, closing the feeding port 407, awaiting the next cycle.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
