Technical Field

[0001] This utility model relates to the field of plastic recycling technology, specifically to a plastic crushing and feeding mechanism. Background Technology

[0002] As people become increasingly reliant on plastic products, a large amount of plastic waste is generated. To avoid serious environmental pollution caused by plastic waste, recycling waste plastics can effectively reduce the amount of waste entering the natural environment, thereby protecting the ecosystem from damage.

[0003] To improve the utilization rate of plastic raw materials, reduce production costs, reduce environmental pollution, and conserve natural resources, plastic crushers are generally used to crush plastics, turning plastic waste into small particles that are easier to store, transport, and process, thereby improving the utilization rate of plastic raw materials. However, it has been found that existing plastic crushers have a simple discharge port structure, which requires frequent changes of the material during the discharge process, making it difficult for on-site staff to make full use of their time. Therefore, it is necessary to design a plastic crushing and feeding mechanism to achieve the distributed feeding of plastic particles. Utility Model Content

[0004] Based on the above description, this utility model provides a plastic crushing and feeding mechanism to solve the problem that the discharge port structure of existing plastic crushers is too simple, which requires operators to frequently change the connecting parts, causing inconvenience.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, there is a space between the bottom surface of the inner receiving cylinder and the bottom surface of the inner cavity of the outer receiving cylinder.

A spring telescopic rod is installed on the bottom surface of the inner cavity of the outer receiving cylinder, and the output end of the spring telescopic rod is designed in a semi-circular shape.

[0023] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0025] Example

[0026] Please refer to Figures 1-5 This embodiment provides a plastic crushing and feeding mechanism, including a base plate 1, a column 11 on the top surface of the base plate 1, the column 11 being rectangular in design, and guide frames 111 on both the left and right sides of the column 11, the two guide frames 111 being located directly below two discharge ports 21 respectively, the guide frames 111 being inclined in design, a receiving outer cylinder 2, the receiving outer cylinder 2 being connected to the top of the column 11, the bottom surface of the receiving outer cylinder 2 being provided with discharge ports 21 respectively near the left and right sides, a top plate 22 being fixedly connected between the left and right sides of the top surface of the receiving outer cylinder 2, a motor 3 being mounted on the top plate 22, a receiving inner cylinder 4, the receiving inner cylinder 4 being located inside the receiving outer cylinder 2, a fixing rod 5 being connected between the receiving inner cylinder 4 and the output end of the motor 3, and a discharge port 41 being provided through the bottom surface of the receiving inner cylinder 4.

[0027] In this embodiment, if it is necessary to collect the crushed plastic granules, the operator can first ensure that the feeding mechanism is located below the discharge port of the external plastic crusher, and place the container below the two guide frames 111. Then, the motor 3 is started, and the crushed plastic granules fall from the outer receiving cylinder 2 into the inner cavity of the inner receiving cylinder 4. After starting, the motor 3 uses the fixing rod 5 to drive the inner receiving cylinder 4 to rotate counterclockwise. During the rotation, the discharge port 2 41 and the two discharge ports 1 21 are repeatedly interconnected, so that the plastic granules in the inner receiving cylinder 4 can be discharged outward in sequence through the repeatedly connected discharge port 2 41 and the two discharge ports 1 21, ensuring that the plastic granules fall evenly into the external container, avoiding the inconvenience caused by the continuous feeding of plastic granules into the same container and the high frequency of subsequent processing.

[0028] As an optional implementation, a space is left between the bottom surface of the inner receiving cylinder 4 and the bottom surface of the inner cavity of the outer receiving cylinder 2. The bottom surface of the inner receiving cylinder 4 is provided with multiple protrusions 42 at equal intervals along the ring. The multiple protrusions 42 are all designed in right-angled triangles. A spring telescopic rod 6 is installed on the bottom surface of the inner cavity of the outer receiving cylinder 2. The output end of the spring telescopic rod 6 is designed in a semi-circular shape. The spring telescopic rod 6 is located between the multiple protrusions 42. The output end of the spring telescopic rod 6 is in contact with the bottom surface of the inner receiving cylinder 4, and the output rod is in a compressed state.

[0029] In this embodiment, the motor 3 uses the fixed rod 5 to drive the receiving inner cylinder 4 to rotate counterclockwise. During the rotation, the output end of the spring telescopic rod 6 contacts the inclined surface of the protrusion 42, and the output rod of the spring telescopic rod 6 gradually retracts downward as the receiving inner cylinder 4 rotates until the output end of the spring telescopic rod 6 moves away from the inclined surface of the protrusion 42. At the instant it moves away from the inclined surface of the protrusion 42, the output rod of the spring telescopic rod 6 rebounds and achieves a knocking effect on the bottom surface of the receiving inner cylinder 4, causing the receiving inner cylinder 4 to vibrate and preventing accidental blockage by plastic particles.

[0030] As an optional implementation, a guide cylinder 43 is provided on the bottom surface of the receiving inner cylinder 4 and near the opening of the discharge port 41, and the bottom surface of the guide cylinder 43 is in contact with the bottom surface of the inner cavity of the receiving outer cylinder 2.

[0031] In this embodiment, the inner receiving cylinder 4 rotates during the rotation process, driving the guide cylinder 43 to rotate simultaneously. The guide cylinder 43 and the discharge port 21 of the outer receiving cylinder 2 are interconnected, which can effectively prevent the plastic particles in the inner receiving cylinder 4 from falling into the inner receiving cylinder 2 through the discharge port 21.

[0032] As an optional implementation, the output end of the spring telescopic rod 6 is provided with a slot 61, and a metal ball 7 is movably connected in the slot 61. The surface of the metal ball 7 is in contact with the bottom surface of the receiving inner cylinder 4.

[0033] In this embodiment, since the bottom surface of the receiving inner cylinder 4 is in contact with the metal ball 7, the receiving inner cylinder 4 can drive the metal ball 7 to rotate simultaneously when it rotates, thus avoiding direct contact between the output end of the spring telescopic rod 6 and the bottom surface of the receiving inner cylinder 4, which would cause wear.

[0034] As an optional implementation, the bottom surface of the receiving inner cylinder 4 is provided with a plurality of protrusions 44, which are close to each other with a plurality of protrusions 42.

[0035] In this embodiment, the output rod of the spring telescopic rod 6 can first contact the surface of the second protrusion 44. The second protrusion 44 rotates simultaneously with the receiving inner cylinder 4, so that the spring telescopic rod 6 can use the second protrusion 44 to achieve a second tapping effect on the receiving inner cylinder 4, ensuring the continuous and smooth feeding of plastic granules.

[0036] As an optional implementation, the surface of the base plate 1 is provided with multiple openings 12, the inner side of the base plate 1 is provided with multiple protrusions 13, and multiple shafts 14 located below the openings 12 are fixedly connected between the multiple protrusions 13, and rollers 8 located inside the openings 12 are sleeved on the outer side of the multiple shafts 14.

[0037] In this embodiment, the designed shaft 14 and roller 8 make it easier for workers to apply pressure to external plastic particles using a container.

[0038] As an optional implementation, the bottom surface of the base plate 1 is fixedly connected with an anti-slip pad 9.

[0039] In this embodiment, the anti-slip pad 9 is used to contact the ground to ensure the stability of the feeding mechanism when it is placed on the ground, and to avoid the phenomenon of sliding displacement that would affect the receiving and collection of plastic particles.

It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
