Description

Technical Field

[0001] This utility model relates to the field of toy processing technology, and in particular to a recycling and crushing machine for waste material from injection molding gates of plastic toys. Background Technology

[0002] In the plastic toy manufacturing industry, injection molding is one of the core processes. However, this process generates a large amount of "gate waste"—excess plastic structures formed when plastic raw materials flow through the injection molding machine nozzle into the mold cavity, passing through the runner and gate (these structures are not part of the finished toy and need to be separated from the finished product after cooling). Plastic toy injection molding gate waste recycling and crushing machines are specifically designed for this type of waste. Their core function is to crush scattered, irregular gate waste into reusable plastic granules, ultimately achieving waste recycling and reducing production losses and costs.

[0003] However, existing plastic toy injection molding gate waste recycling crushers often use relatively simple crushing mechanisms, which not only results in low crushing efficiency but also makes it difficult to fully and uniformly crush the waste, affecting the quality of the recycled waste. Therefore, this utility model proposes a plastic toy injection molding gate waste recycling crusher. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a recycling and crushing machine for waste material from injection molding gates of plastic toys.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A recycling and crushing machine for waste injection molding of plastic toys includes a frame and a crushing hopper fixedly installed on the top of the frame. A feed inlet is located on the top left side of the crushing hopper. A disc-shaped crushing shell is fixedly connected to the bottom of the crushing hopper along the inner side of the frame. A horn-shaped discharge cylinder is located at the bottom of the disc-shaped crushing shell, and a collection box is located below the horn-shaped discharge cylinder. A lifting rod is movably installed inside the crushing hopper via a drive mechanism. Crushing crossbeams are located on both sides of the lifting rod. Multiple crushing blades for preliminary crushing of the recycled waste injection molding of plastic toys are located at the top and bottom of the crushing crossbeams. A first filter port is located between the bottom opening of the crushing hopper and the top of the disc-shaped crushing shell, and a first filter screen is installed at the first filter port.

[0007] A crushing wheel is rotatably installed inside the disc-shaped crushing shell, and a crushing motor is fixedly installed on the outside of the disc-shaped crushing shell. The output shaft of the crushing motor rotatably passes through the disc-shaped crushing shell and is fixedly connected to the crushing wheel. A second filter port is provided at the bottom of the disc-shaped crushing shell, and a second filter screen is provided inside the second filter port.

[0008] Furthermore, the drive mechanism includes a mounting bracket located at the top right end of the crushing funnel, a drive motor fixedly mounted on the mounting bracket, a drive gear fixedly mounted on the output shaft of the drive motor, the top of the lifting rod movably extending through to the top of the crushing funnel, the lifting rod located above the crushing funnel having a toothed groove, and the drive gear engaging with the toothed groove on the lifting rod.

[0009] Furthermore, a guide frame is fixedly installed on the crushing hopper located on the left side of the lifting rod. The guide frame is provided with a sliding groove. A sliding block is fixedly installed on the left side of the lifting rod. The sliding block is slidably installed in the sliding groove in the vertical direction.

[0010] Furthermore, the top inner wall of the crushing funnel is provided with an installation hole, and a sealing sleeve is fixedly installed in the installation hole. The lifting movable rod located below the tooth groove slides through the sealing sleeve in the vertical direction.

[0011] Furthermore, the inner circumferential wall of the disc-shaped crushing shell is uniformly provided with a plurality of auxiliary crushing teeth, and the crushing wheel is adapted to the auxiliary crushing teeth.

[0012] Furthermore, a controller is provided on the outside of the crushing hopper, and the controller is electrically connected to the crushing motor and the drive motor respectively.

[0013] The beneficial effects achieved by this utility model using the above structure are as follows:

[0014] 1. In this utility model, the output shaft of the drive motor drives the drive gear to rotate forward and backward. When the drive gear rotates, it meshes with the tooth groove on the lifting rod, thereby driving the lifting rod to move up or down. The lifting rod also drives the crushing head to reciprocate up and down through the crushing crossbeam. Thus, the waste material is cut and crushed by the up and down crushing action of the crushing head, thereby enabling larger waste materials to be cut and crushed into smaller sizes.

[0015] 2. In this utility model, the output shaft of the crushing motor drives the crushing wheel to rotate, thereby crushing the waste material. At the same time, the centrifugal motion generated by the crushing wheel during the rotation crushing motion can throw the waste material to all sides and impact it onto the auxiliary crushing teeth on the inner circumference of the disc-shaped crushing shell. In this way, the waste material can be further crushed through the crushing cooperation of the auxiliary crushing teeth.

[0016] In summary, this plastic toy injection molding gate waste recycling and crushing machine, through the combination of multiple crushing structures, can quickly crush the recycled plastic toy injection molding gate waste, avoiding the low crushing efficiency caused by the simple crushing structure used in the past. It can also crush the waste thoroughly and evenly, greatly improving the quality of waste recycling and crushing. Moreover, the structure is simple and easy to operate. Attached Figure Description

A lifting rod 8 is movably installed inside the crushing funnel 2 via a drive mechanism. Crushing crossbeams 10 are provided on both sides of the lifting rod 8. Multiple crushing crossbeams 10 are provided at the top and bottom of the crushing crossbeams 10 for... A crushing head 11 is used for preliminary crushing of recycled plastic toy injection molding waste; a first filter port 307 is provided between the bottom funnel opening of the crushing hopper 2 and the top of the disc-shaped crushing shell 3, and a first filter screen 308 is provided at the first filter port 307; a crushing wheel 303 is rotatably installed inside the disc-shaped crushing shell 3, and a crushing motor 302 is fixedly installed on the outside of the disc-shaped crushing shell 3, and the output shaft of the crushing motor 302 rotatably passes through the disc-shaped crushing shell 3 and is fixedly sleeved with the crushing wheel 303; a second filter port 305 is provided at the bottom of the disc-shaped crushing shell 3, and a second filter screen 306 is provided inside the second filter port 305.

[0024] The drive mechanism includes a mounting bracket 5 located at the top right end of the crushing hopper 2. A drive motor 6 is fixedly mounted on the mounting bracket 5. A drive gear 7 is fixedly mounted on the output shaft of the drive motor 6. The top of the lifting rod 8 extends through to the top of the crushing hopper 2. The lifting rod 8 located above the crushing hopper 2 is provided with a toothed groove 801, and the drive gear 7 engages with the toothed groove 801 on the lifting rod 8.

[0025] In this embodiment, a guide frame 9 is fixedly installed on the crushing funnel 2 located on the left side of the lifting rod 8. The guide frame 9 is provided with a sliding groove 902. A sliding block 901 is fixedly installed on the left side of the lifting rod 8. The sliding block 901 is slidably installed in the sliding groove 902 in the vertical direction.
