[0003] A PVC pipe fitting automatic weighing and feeding device with the Chinese patent number CN216782599U includes: a small material batching machine, and a batching machine control electric cabinet is arranged on one side of the small material batching machine. The feeding speed is faster, avoiding dust pollution. During the overall use, the batching and discharging speed is faster, the batching is more accurate, labor is saved, and the production cost of PVC pipe fittings is saved.

[0004] When some materials are being sucked, there will be a phenomenon of adhesion and attachment to the inner wall of the feeding storage frame, which is not conducive to ensuring the adsorption effect of the materials and is prone to the phenomenon of residual materials. Therefore, it is necessary to design an automatic feeding device for PVC plastic particle production with a material ejecting function to solve the above problems.

[0005] For this reason, an automatic feeding device for PVC plastic particle production is proposed. Content of the Utility Model

[0007] The technical solution of the utility model is realized as follows: an automatic feeding device for PVC plastic particle production includes a feeding storage frame, a suction inner pipe penetrates through the inner end of the feeding storage frame, a sliding outer sleeve is sleeved on the outer end of the suction inner pipe, a self-sliding cross plate is fixedly connected to one end of the sliding outer sleeve far away from the suction inner pipe, a round table is fixedly connected to the upper end of the self-sliding cross plate, electric push rods are fixedly connected to the four corners of the outer end of the round table, a leather-faced ball hammer is fixedly connected to the output end of the electric push rod, an internal iron sheet frame is installed on the inner side of the feeding storage frame, a hollow inner groove is arranged between the internal iron sheet frame and the feeding storage frame, and a plurality of internal springs are fixedly connected to the outer side wall of the internal iron sheet frame.

[0008] Further preferably, one end of the internal spring far away from the internal iron sheet frame is connected to the inner side wall of the hollow inner groove, and the internal spring is located inside the hollow inner groove.

[0009] Further preferably, the leather-faced ball hammer cooperates with the internal spring, and the leather-faced ball hammer contacts the inner side wall of the internal iron frame.

[0010] Further preferably, a lengthened suction pipe is installed at the inner end of the material suction inner pipe, and a pump is externally connected to the lengthened suction pipe.

Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0027] The following will detail the embodiments of the present utility model with reference to the drawings.

[0028] Embodiment 1

[0029] As Figures 1-5As shown in the figure, the embodiment of the present utility model provides an automatic feeding device for the production of PVC plastic particles, which includes a feeding storage frame 1. A suction inner pipe 7 penetrates through the inner end of the feeding storage frame 1. A sliding outer sleeve 6 is sleeved on the outer end of the suction inner pipe 7. One end of the sliding outer sleeve 6 away from the suction inner pipe 7 is fixedly connected to a self-sliding horizontal plate 8. A round table 9 is fixedly connected to the upper end of the self-sliding horizontal plate 8. Electric push rods 10 are fixedly connected to the four corners of the outer end of the round table 9. The output end of the electric push rod 10 is fixedly connected to a leather-faced ball hammer 12. An internal iron frame 3 is installed inside the feeding storage frame 1. A hollow inner groove 4 is provided between the internal iron frame 3 and the feeding storage frame 1. A plurality of internal springs 5 are fixedly connected to the outer side wall of the internal iron frame 3.

[0030] One end of the internal spring 5 away from the internal iron frame 3 is connected to the inner side wall of the hollow inner groove 4. The internal spring 5 is located inside the hollow inner groove 4. The leather-faced ball hammer 12 cooperates with the internal spring 5. The leather-faced ball hammer 12 contacts the inner side wall of the internal iron frame 3. A lengthened suction pipe 13 is installed at the inner end of the suction inner pipe 7. The lengthened suction pipe 13 is externally connected to a pump. A plurality of support columns 2 are fixedly connected to the lower end of the feeding storage frame 1. The plurality of support columns 2 are located at the four corner positions of the lower end of the feeding storage frame 1.

[0031] Embodiment 2

[0032] In one embodiment, a number of materials are filled in the inner end of the internal iron frame 3. A filter screen 14 is fixedly connected to the end of the suction inner pipe 7 away from the lengthened suction pipe 13. A number of sieve holes are provided on the surface of the filter screen 14.

[0033] The materials penetrate inside and outside the corresponding sieve holes. The filter screen 14 cooperates with the materials. The self-sliding horizontal plate 8 is located directly above the materials.

[0034] When the utility model is in operation: In this solution, the material is filled in the feeding storage frame 1, and the extended suction pipe 13 in the inner suction pipe 7 is externally connected to a pump to suck all the material into the processing equipment for subsequent processing operations. However, when some of the material is being sucked, there will be a phenomenon of adhesion to the inner wall of the feeding storage frame 1, which is not conducive to ensuring the suction effect of the material and is likely to cause residual material. Therefore, a sliding outer sleeve 6 is installed outside the inner suction pipe 7 in the feeding storage frame 1. The initial position of the sliding outer sleeve 6 is above the material. During the suction process of the inner suction pipe 7, the self-sliding cross plate 8 moves downward from top to bottom in the feeding storage frame 1 following the slope of the material. During the displacement process, multiple electric push rods 10 outside the frustum 9 can generate a bouncing hammering force on the inner wall of the internal iron sheet frame 3 by using the leather-faced ball hammer 12 to assist in smoothly moving the material downward for suction. And when the leather-faced ball hammer 12 contacts the internal iron sheet frame 3, the leather-faced ball hammer 12 can correspond to the internal spring 5, causing the internal iron sheet frame 3 to generate a resilience force. This resilience force can bounce off the material adhering to the inner side wall of the internal iron sheet frame 3, further ensuring the suction feeding effect of the material and not easily causing residual material. At the same time, a filter screen 14 is also provided below the inner suction pipe 7. The filter screen 14 can filter the material in the feeding storage frame 1 during the suction process to prevent caked or adhered material from being sucked into the inner suction pipe 7 and causing blockage inside the inner suction pipe 7, thereby ensuring the feeding effect of the inner suction pipe 7.

[0035] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art in the technical field disclosed by the utility model can easily think of various changes or substitutions within the technical scope disclosed by the utility model, and these should all be covered by the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
