[0003] In the plastics production process, crushers play an important role in crushing plastics. However, a problem exists in actual use: when too much plastic is fed into the crusher, the excess plastic cannot be properly dispersed in the limited space, and some plastic is discharged directly before it even touches the rollers, resulting in uneven crushing. This greatly reduces the practicality of the crusher. Utility Model Content

[0004] The purpose of this utility model is to provide a crusher for plastic production, which aims to solve the problem in the existing technology that when plastic is fed into the crusher, if the amount of plastic is too large, the excess plastic cannot be fully dispersed in the limited space, and some plastic is discharged directly before it even touches the rollers, resulting in uneven crushing. This greatly reduces the practicality of the crusher.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crusher for plastic production, comprising a crushing box, a first crushing mechanism installed inside the crushing box, a conveying mechanism installed inside the crushing box, a discharge hopper connected to the bottom end of the crushing box, a guide plate connected to the top end of the crushing box, and a screening screen installed at an incline inside the crushing box. The first crushing mechanism is composed of a first crushing roller and a drive motor, the conveying mechanism is composed of an auger and a stepper motor, a storage box is installed at the front end of the crushing box, a second crushing mechanism is installed inside the storage box, a discharge hopper is connected to the bottom end of the storage box, insert blocks are connected to both sides of the storage box, a rectangular block is connected to one side of the crushing box, a fixing block is connected to the other side of the crushing box, bolts are threaded through the sidewall of the rectangular block, a pull rod is inserted inside the fixing block, a spring is sleeved on the surface of the pull rod, and an extrusion block is fixedly connected to the surface of the pull rod.

[0006] As a preferred embodiment of the pulverizer for plastic production according to this utility model, the second pulverizing mechanism includes a second pulverizing roller and a servo motor. The second pulverizing roller is connected inside the storage box, and the servo motor is connected to the side wall of the storage box. The output shaft of the servo motor passes through the storage box and is connected to the second pulverizing roller. The two second pulverizing rollers rotate in opposite directions through gears.

[0007] In a preferred embodiment of the plastic production crusher of this utility model, the discharge hopper extends into the interior of the crushing chamber.

[0008] As a preferred embodiment of the plastic production crusher of this utility model, the plug-in block connected to one side of the storage box can be detachably connected to the rectangular block by bolts.

[0009] As a preferred embodiment of the plastic production crusher of this utility model, the pull rod can be elastically telescopically connected to the fixed block through a spring and an extrusion block.

[0011] In a preferred embodiment of the plastic production crusher of this utility model, the pull rod and the extrusion block are integrally connected, and the pull rod and the extrusion block are in the shape of a "T".

[0012] Compared with the prior art, the beneficial effects of this utility model are: Through the coordination of the screening screen, the collection box, the second crushing mechanism, and the discharge hopper, the equipment operates by placing plastic on the guide plate and allowing it to flow along the inclined surface of the guide plate into the first crushing mechanism. The plastic is then crushed by the first crushing mechanism, and the crushed plastic falls onto the screening screen, flowing along its inclined surface. Plastic smaller than the screen opening passes through the screen and falls into the crushing box. The crushed plastic is then conveyed to the discharge hopper and discharged, while plastic larger than the screen opening falls into the collection box and into the second crushing mechanism within the collection box. There, it undergoes secondary crushing, and the crushed plastic flows back into the crushing box through the discharge hopper. Finally, it is conveyed to the discharge hopper for discharge. This process avoids uneven crushing of the plastic, greatly improving the practicality of the crusher.

[0013] By utilizing the interlocking blocks, rectangular blocks, fixing blocks, bolts, springs, compression blocks, and pull rods, the operator unscrews the bolts, thus connecting the interlocking blocks and rectangular blocks. Then, pulling the pull rod moves the compression block, causing the spring to compress and contract. Simultaneously, the movement of the pull rod disengages from the interlocking blocks and fixing blocks. This simplifies and speeds up the assembly and disassembly of the storage box, allowing operators to quickly and efficiently complete the disassembly and installation. This also facilitates regular inspection, repair, and maintenance of the secondary crushing mechanism inside the storage box, effectively extending the equipment's lifespan and improving its operational stability and reliability.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5This utility model provides the following technical solution: a crusher for plastic production, including a crushing box 1, a first crushing mechanism 2 installed inside the crushing box 1, a conveying mechanism 3 installed inside the crushing box 1, a discharge hopper 4 connected to the bottom end of the crushing box 1, a guide plate 5 connected to the top end of the crushing box 1, a screening screen 6 installed at an incline inside the crushing box 1, the first crushing mechanism 2 is composed of a first crushing roller 21 and a drive motor 22, the conveying mechanism 3 is composed of an auger 31 and a stepper motor 32, a storage box 7 is installed at the front end of the crushing box 1, a second crushing mechanism 8 is installed inside the storage box 7, a discharge hopper 9 is connected to the bottom end of the storage box 7, plug-in blocks 10 are connected to both sides of the storage box 7, a rectangular block 11 is connected to one side of the crushing box 1, a fixing block 12 is connected to the other side of the crushing box 1, a bolt 13 is threaded through the side wall of the rectangular block 11, a pull rod 16 is inserted inside the fixing block 12, a spring 14 is sleeved on the surface of the pull rod 16, and an extrusion block 15 is fixedly connected to the surface of the pull rod 16.

[0018] In practical use, the crusher mainly consists of a crushing box 1, a first crushing mechanism 2, a conveying mechanism 3, a discharge hopper 4, and a screening screen 6. When the equipment is running, the plastic is first placed on the guide plate 5. The plastic will flow into the first crushing mechanism 2 along the inclined surface of the guide plate 5. Then, the plastic is crushed by the first crushing mechanism 2. The crushed plastic will fall onto the screening screen 6 and flow along the inclined surface of the screening screen 6. During the flow, the plastic with a size smaller than the mesh opening of the screening screen 6 will pass through the screening screen 6 and fall into the crushing box 1. Then, the crushed plastic is conveyed to the discharge hopper 4 by the conveying mechanism 3 and finally discharged through the discharge hopper 4.

[0019] It should be noted that the first crushing mechanism 2 consists of a first crushing roller 21 and a drive motor 22. When in use, the drive motor 22 is first connected to the power supply and started. The drive motor 22 drives the first crushing roller 21 to rotate. The two first crushing rollers 21 rotate in opposite directions through gears. At this time, the plastic is placed on the guide plate 5. The plastic flows into the space between the two first crushing rollers 21 along the inclined surface of the guide plate 5 and is then crushed by the two first crushing rollers 21.

[0020] The conveying mechanism 3 consists of an auger 31 and a stepper motor 32. When in use, the stepper motor 32 is first connected to the power supply and started. The stepper motor 32 drives the auger 31 to rotate. The crushed plastic is conveyed to the discharge hopper 4 through the auger 31 and finally discharged through the discharge hopper 4.

[0021] Preferably, the second crushing mechanism 8 includes a second crushing roller 81 and a servo motor 82. The second crushing roller 81 is connected inside the storage box 7, and the servo motor 82 is connected to the side wall of the storage box 7. The output shaft of the servo motor 82 passes through the storage box 7 and is connected to the second crushing roller 81. The two second crushing rollers 81 rotate in opposite directions via gears. The discharge hopper 9 extends into the interior of the crushing box 1. The plug-in block 10 connected to one side of the storage box 7 can be detachably connected to the rectangular block 11 via bolts 13. The pull rod 16 can be elastically telescopically connected to the fixed block 12 via spring 14 and pressing block 15. The plug-in block 10 connected to the other side of the storage box 7 can be elastically engaged with the fixed block 12 via pull rod 16 and spring 14. The pull rod 16 and pressing block 15 are integrally connected and are T-shaped.

[0022] In practical use, when the equipment is in use, plastic larger than the mesh opening of the screening screen 6 will fall down the inclined surface into the collection box 7, and then fall into the second crushing mechanism 8 inside the collection box 7, where it will be crushed a second time. The crushed plastic will then flow back into the crushing box 1 through the discharge hopper 9, and then be sent to the discharge hopper 4 for discharge through the conveying mechanism 3. This avoids uneven crushing of the plastic and greatly improves the practicality of the crusher.

[0023] Next, the operator unscrews bolt 13, thereby connecting the plug-in block 10 and the rectangular block 11. Then, the operator pulls the lever 16 to move it, which in turn moves the compression block 15, causing the spring 14 to contract. At the same time, the movement of the lever 16 disengages it from the plug-in block 10 and the fixing block 12. This makes the disassembly and assembly of the storage box 7 simple and quick. The operator can quickly and efficiently complete the disassembly and assembly of the storage box 7, which facilitates the regular inspection, maintenance, and upkeep of the second crushing mechanism 8 inside the storage box 7. This effectively extends the service life of the equipment and improves the stability and reliability of its operation.

[0024] It is worth noting that the second crushing mechanism 8 is composed of a second crushing roller 81 and a servo motor 82. When in use, the servo motor 82 is first connected to the power supply and started. The servo motor 82 drives the second crushing roller 81 to rotate. The two second crushing rollers 81 rotate in opposite directions through gears. At this time, plastic larger than the mesh opening of the screening screen 6 will fall down the inclined surface into the storage box 7, and then fall between the two second crushing rollers 81 for secondary crushing.

[0025] Working principle: When the equipment is working, the operator first places the plastic on the guide plate 5. The plastic will flow into the first crushing mechanism 2 along the inclined surface of the guide plate 5. Then, the plastic is crushed by the first crushing mechanism 2. The crushed plastic falls onto the screen 6 and flows along the inclined surface of the screen 6. During the flow, the plastic with a size smaller than the opening of the screen 6 will pass through the screen 6 and fall into the crushing box 1. Then, it is conveyed to the discharge hopper 4 by the conveying mechanism 3 and finally discharged through the discharge hopper 4.

[0026] Plastics larger than the mesh opening of the screening screen 6 will fall into the collection box 7 and into the second crushing mechanism 8 inside the collection box 7, where they will be crushed a second time. The crushed plastics will then flow back into the crushing box 1 through the discharge hopper 9 and be conveyed to the discharge hopper 4 by the conveying mechanism 3. This effectively avoids the problem of uneven crushing of plastics and greatly improves the practicality of the crusher.

[0027] When the storage box 7 needs to be disassembled and maintained, the operator first unscrews bolt 13 to disconnect the connection between the plug block 10 and the rectangular block 11, and then pulls the lever 16 to move it. When the lever 16 moves, it will drive the squeezing block 15 to move, causing the spring 14 to contract. At the same time, the movement of the lever 16 will also disconnect it from the plug block 10 and the fixing block 12. In this way, the disassembly and assembly process of the storage box 7 becomes simple and quick. The operator can quickly and efficiently complete the disassembly and assembly of the storage box 7, which facilitates the regular inspection, maintenance and upkeep of the second crushing mechanism 8 inside the storage box 7, effectively extending the service life of the equipment and improving the stability and reliability of the equipment operation.

[0028] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
