Technical Field
[0001] This utility model relates to the field of plastic product crushing technology, and in particular to a plastic product crushing device. Background Technology
[0002] Plastic product crushing is the process of turning waste plastic products into small particles or powder using mechanical equipment. This process is commonly used for the recycling and reuse of plastic waste, as well as the reprocessing of plastic products.
[0003] Plastic product crushers are specialized equipment used for the mechanical crushing of waste plastic products. Plastic products are fed into the crusher through its inlet. However, with existing plastic product crushers, plastic products tend to accumulate and clog the inlet, preventing them from falling into the crushing machine and affecting crushing efficiency. This requires manual handling by operators, which is not only labor-intensive but also poses certain operational risks.
[0004] Therefore, we propose a plastic product crushing device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plastic product crushing device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A plastic product crushing device includes a housing. Two first support plates, arranged symmetrically to the left and right, are fixedly connected to the front end of the housing. A first rotating rod is rotatably connected between the two first support plates. A first sprocket is fixedly sleeved on the first rotating rod. A motor for driving the first rotating rod is fixedly installed on one of the first support plates away from the other. An extension plate is fixedly connected to the front end of the housing. Two second support plates, arranged symmetrically to the left and right, are fixedly connected to the upper end of the extension plate. A second rotating rod is rotatably connected between the two second support plates. A second sprocket is fixedly sleeved on the second rotating rod. An opening is provided on the extension plate. A chain is sleeved on both the first and second sprockets, passing through the opening on the extension plate. A cam is fixedly sleeved on the second rotating rod.
[0008] Preferably, a fixing plate is fixedly connected to the upper end of the device housing, and a feed inlet is connected to the upper end of the device housing. A collision plate is provided between the fixing plate and the feed inlet. Two sliding rods are fixedly connected to the front end of the collision plate, which are arranged on the left and right sides respectively. Both sliding rods pass through the fixing plate and are slidably connected to it. A rectangular block is fixedly connected to the front end of each of the two sliding rods. A rotating roller is rotatably connected between the two rectangular blocks. A spring is sleeved on each of the two sliding rods. One end of each spring is fixedly connected to the collision plate and the other end is fixedly connected to the fixing plate.
[0009] Preferably, the device housing has two rotatably connected between the front and rear inner walls and two corresponding crushing rollers, and the front end of the device housing has two second bevel gears rotatably connected, with the two second bevel gears being coaxially fixedly connected to the two crushing rollers respectively.
[0010] Preferably, two first bevel gears are fixedly sleeved on the first rotating rod, which are arranged symmetrically on the left and right, and the two second bevel gears mesh with the two first bevel gears respectively.
[0011] Preferably, a base plate is fixedly connected to the lower end of the device housing, and an inverted trapezoidal groove is provided on the upper end of the base plate, with a discharge port on the bottom wall of the groove.
[0012] Preferably, four support columns are fixedly connected to the lower end of the base plate, and the four support columns are located at the four corners of the base plate.
[0013] Compared with existing technologies, the advantages of this device are:
[0014] 1. This device can cause the impact plate to reciprocate and strike the feed inlet through different rotations of the cam, making the feed inlet vibrate continuously and preventing material blockage in the feed inlet. Moreover, the rotation of the cam is driven by a chain, and the rotation of the crushing roller is driven by a bevel gear. The entire device only needs one motor to drive it, saving production costs.
[0015] In summary, this device requires only one motor for driving, and the impact plate repeatedly strikes the feed inlet while the crushing roller is working to prevent blockage. It has low production costs and strong practicality. Attached Figure Description

[0020] 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.
[0021] Reference Figures 1-3 A plastic product crushing device includes a device housing 1. Two first support plates 2, arranged left and right, are fixedly connected to the front end of the device housing 1. A first rotating rod 3 is rotatably connected between the two first support plates 2. A first sprocket 5 is fixedly sleeved on the first rotating rod 3. A motor 23 for driving the first rotating rod 3 is fixedly installed at the end of one of the first support plates 2 away from the other. An extension plate 6 is fixedly connected to the front end of the device housing 1. Two second support plates 7, arranged left and right, are fixedly connected to the upper end of the extension plate 6. A second rotating rod 8 is rotatably connected between the two second support plates 7. A second sprocket 9 is fixedly sleeved on the second rotating rod 8. An opening is provided on the extension plate 6. A chain 10 is sleeved on both the first sprocket 5 and the second sprocket 9. The chain 10 passes through the opening on the extension plate 6. A cam 11 is fixedly sleeved on the second rotating rod 8. When the motor 23 drives the first rotating rod 3 to rotate, the first sprocket 5 on the first rotating rod 3 rotates synchronously. The first sprocket 5 drives the second sprocket 9 to rotate through the chain 10, thereby causing the second rotating rod 8 to rotate synchronously. The rotation of the second rotating rod 8 causes the cam 11 fixedly sleeved on it to rotate accordingly.
[0022] A fixing plate 12 is fixedly connected to the upper end of the device housing 1. A feed inlet 18 is connected to the upper end of the device housing 1. A bumper 16 is provided between the fixing plate 12 and the feed inlet 18. Two sliding rods 13 are fixedly connected to the front end of the bumper 16, which are arranged on the left and right respectively. Both sliding rods 13 pass through the fixing plate 12 and are slidably connected to it. A rectangular block 14 is fixedly connected to the front end of each of the two sliding rods 13. A rotating roller 15 is rotatably connected between the two rectangular blocks 14. A spring 17 is sleeved on each of the two sliding rods 13. One end of each spring 17 is fixedly connected to the bumper 16 and the other end is fixedly connected to the fixing plate 12. In the initial state, the impact plate 16 is pressed against the feed inlet 18 by the elastic force of the spring 17. When the cam 11 rotates to make rolling contact with the rotating roller 15, it pushes the rotating roller 15 forward. When the rotating roller 15 pushes forward, it drives the two sliding rods 13 to slide forward through the two rectangular blocks 14, thereby causing the impact plate 16 to move forward. At this time, the impact plate 16 squeezes the two springs 17 towards the fixed plate 12. When the cam 11 separates from the rotating roller 15, the elastic force of the spring 17 causes the impact plate 16 to hit the feed inlet 18, thereby achieving the oscillation effect of the feed inlet 18. The continuous rotation of the cam 11 causes the impact plate 16 to repeatedly hit the feed inlet 18, preventing material blockage in the feed inlet 18.
[0023] Two crushing rollers 19, arranged symmetrically on the left and right, are rotatably connected between the front and rear inner walls of the device housing 1. Two second bevel gears 20 are rotatably connected to the front end of the device housing 1, and the two second bevel gears 20 are coaxially fixedly connected to the two crushing rollers 19 respectively. Two first bevel gears 4, arranged symmetrically on the left and right, are fixedly sleeved on the first rotating rod 3, and the two second bevel gears 20 mesh with the two first bevel gears 4 respectively. When the motor 23 controls the first rotating rod 3 to rotate forward, thereby driving the two first bevel gears 4 to rotate forward, it drives the two second bevel gears 20 meshing with them to rotate. Since the two first bevel gears 4 are symmetrically arranged, the two second bevel gears 20 rotate in opposite directions and rotate towards each other, thereby driving the two crushing rollers 19 to rotate towards each other. The material falling through the feed inlet 18 falls between the two crushing rollers 19, and the two crushing rollers 19 rotate relative to each other, crushing the material.
[0024] A base plate 21 is fixedly connected to the lower end of the device housing 1. An inverted trapezoidal groove is formed at the upper end of the base plate 21, and a discharge port is formed on the bottom wall of the groove. Four support columns 22 are fixedly connected to the lower end of the base plate 21, located at the four corners of the base plate 21. The material crushed by the two crushing rollers 19 falls into the inverted trapezoidal groove of the base plate 21 and slides downwards, discharging through the discharge port formed on the bottom wall of the groove.
[0025] When using this utility model, the operator puts the plastic product into the device through the feed inlet 18. The material is crushed by the relative rotation of the two crushing rollers 19. At the same time, the different rotations of the cam 11 cause the impact plate 16 to repeatedly hit the feed inlet 18, making the feed inlet 18 vibrate continuously to prevent material blockage in the feed inlet 18. The material crushed by the two crushing rollers 19 falls into the inverted trapezoidal groove of the bottom plate 21 and slides downwards. The material is discharged through the discharge port opened on the bottom wall of the groove.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
