Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a plastic raw material crushing equipment. Background Technology

[0002] Plastics are a class of synthetic polymer materials with plasticity. Together with synthetic rubber and synthetic fibers, they form the three major synthetic materials that are indispensable in our daily lives. Specifically, plastics are materials made primarily of natural or synthetic resins with the addition of various additives. They can be molded into a certain shape under certain temperature and pressure conditions and retain their shape at room temperature. Plastics require the raw materials to be crushed before processing.

[0003] However, the existing plastic crushing equipment has a relatively simple crushing structure, which only crushes the raw materials by high-speed rotating crushing blades. This can easily lead to some raw materials not coming into contact with the crushing blades, resulting in incomplete crushing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a plastic raw material crushing equipment that can repeatedly pour the raw material so that the raw material can be evenly contacted by the crushing blades, making the crushing more thorough.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a plastic raw material crushing device, including a base, a support frame fixedly connected to the base, a roller fixedly connected to the upper end of the support frame, a crushing tank provided at the center of the roller shaft, a crushing mechanism provided inside the crushing tank, and guide boxes symmetrically arranged and slidably connected to both ends of the crushing tank and the inner wall of the roller, with a discharge port provided between the crushing tank and the guide boxes, and a pull-out hole provided at one end of the guide box, with a collection box slidably inserted into the pull-out hole; a gear ring arranged coaxially with the roller is fixedly sleeved on the outer wall of the guide boxes on both sides, an annular limiting groove that mates with the gear ring is provided on the inner wall of the roller, and a through hole communicating with the annular limiting groove is provided on the outer wall of the roller, a gear located in the through hole and meshing with the gear ring is rotatably connected inside the support frame, and a first motor that drives the gear to rotate is fixedly connected to the support frame.

[0006] As an improvement, the crushing mechanism includes a crushing shaft rotatably connected inside the crushing tank, at least one crushing blade fixedly connected to the outer wall of the crushing shaft, and a second motor for driving the crushing shaft to rotate fixedly connected to one end of the crushing tank.

[0007] As an improvement, the collection box has a fixed cavity at one end, and sliding holes communicating with the fixed cavity are provided on both sides of the collection box. Fixed blocks extending into the fixed cavity are slidably inserted into the sliding holes. Fixed slots that cooperate with the fixed blocks are provided on both sides of the pull hole. A partition is fixedly connected to the center of the fixed cavity. A fixed spring is fixedly connected between the partition and the fixed blocks. A lever is fixedly connected to one side of the fixed blocks. An adjustment hole that cooperates with the lever is provided at one end of the collection box.

[0008] As an improvement, guide rings are fixedly sleeved on the outer walls of the guide boxes on both sides, and the inner wall of the roller is provided with an annular groove that cooperates with the guide rings.

[0009] As an improvement, a pusher plate is slidably inserted into the collection box, and baffles are arranged on both sides of the opening end of the collection box.

[0010] The advantages of this utility model compared with the prior art are as follows: the plastic raw material to be crushed is placed into the guide box through the collection box, and the drive gear ring drives the guide boxes on both sides to rotate along the inner wall of the drum. When the guide box containing the raw material rotates to the top, the raw material enters the crushing tank through the discharge port under the action of gravity. The raw material is crushed by the crushing mechanism. With the cyclic rotation of the guide boxes on both sides, the raw material continuously falls into the crushing tank for crushing, resulting in more thorough crushing. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 5 As shown, a plastic raw material crushing device includes a base 1, a support frame 2 fixedly connected to the base 1, a roller 3 fixedly connected to the upper end of the support frame 2, a crushing tank 4 provided at the axis of the roller 3, a crushing mechanism provided inside the crushing tank 4, the crushing mechanism including a crushing shaft 25 rotatably connected inside the crushing tank 4, at least one crushing blade 26 fixedly connected to the outer wall of the crushing shaft 25, and a second motor 24 fixedly connected to one end of the crushing tank 4 to drive the crushing shaft 25 to rotate.

[0019] Both ends of the crushing tank 4 are fixedly connected to guide boxes 5 symmetrically arranged and slidably connected to the inner wall of the drum 3. A discharge port is provided between the crushing tank 4 and the guide boxes 5. One end of each guide box 5 has a pull-out hole 7, into which a collection box 6 is slidably inserted. One end of each collection box 6 has a fixed cavity 22. Both sides of the collection box 6 have sliding holes 20 communicating with the fixed cavity 22. Fixed blocks 16 extending into the fixed cavity 22 are slidably inserted into each sliding hole 20. Both sides of the pull-out hole 7 are provided with fixing slots 21 that cooperate with the fixing block 16. A partition 23 is fixedly connected to the center of the fixing cavity 22. A fixing spring 17 is fixedly connected between the partition 23 and the fixing block 16. A lever 18 is fixedly connected to one side of the fixing block 16. One end of the collection box 6 is provided with an adjustment hole 19 that cooperates with the lever 18. A pusher plate is slidably inserted into the collection box 6. The opening end of the collection box 6 is provided with baffles 15 arranged on both sides.

[0020] The outer walls of the guide boxes 5 on both sides are fixedly fitted with gear rings 8 arranged coaxially with the roller 3. The inner wall of the roller 3 is provided with an annular limiting groove 11 that cooperates with the gear ring 8. The outer wall of the roller 3 is provided with a through hole 12 that communicates with the annular limiting groove 11. The support frame 2 is rotatably connected with a gear 9 located in the through hole 12 and meshing with the gear ring 8. The support frame 2 is fixedly connected with a first motor 10 that drives the gear 9 to rotate. The outer walls of the guide boxes 5 on both sides are fixedly fitted with guide rings 13 arranged on both sides. The inner wall of the roller 3 is provided with an annular rotating groove 14 that cooperates with the guide ring 13.

[0021] In practical use, the collection box 6 is pulled out, and the plastic raw material to be crushed is added into the collection box 6. Pressing the levers 18 on both sides drives the fixing blocks 16 on both sides to extend into the sliding holes 20 on both sides, compressing the fixing springs 17 on both sides. After the pull-out box is fully inserted into the collection box 6, the levers 18 on both sides are released. Under the restoring force of the fixing springs 17 on both sides, the fixing blocks 16 on both sides are pushed into the fixing slots 21 on both sides to prevent the collection box 6 from falling out of the pull-out hole 7. The second motor 24 is started to drive the crushing shaft 25 to rotate, and the crushing shaft 25 drives the crushing blades 26 to rotate at high speed. When the first motor 10 is activated, it drives the gear 9 to rotate. The gear 9 drives the gear ring 8 to rotate. The gear ring 8 drives the guide boxes 5 on both sides and the crushing tank 4 to rotate. When the guide box 5 containing raw materials rotates to the top, the raw materials flow out from the collection box 6 under the action of gravity and enter the crushing tank 4 through the discharge port. At the same time, the pusher plate slides down under the action of gravity, further pushing the raw materials in the collection box 6 out. The raw materials enter the crushing tank 4 and are crushed by the high-speed rotation of the crushing blades 26 and fall into the collection box 6 below. With the alternating up and down movement of the two collection boxes 6, the raw materials are crushed more thoroughly.
