[0001] The utility model belongs to the technical field of crushing devices, and particularly relates to a polyamide waste recycling and crushing device. Background Technique
[0002] Polyamide waste mainly comes from scraps and unqualified products during the production process, as well as scrapped parts and products during use.
[0003] A polyamide waste recycling and crushing device is a device specifically used to process polyamide waste. It can crush the waste into particles or powders suitable for reuse.
[0004] In the process of recycling polyamide waste, although a crushing device is used to crush it, there is a key problem: when the crushing device discharges materials through the discharge hopper, there is a lack of an effective material leveling device. This leads to uneven discharging, which may further affect the efficiency and quality of subsequent processes. Specifically, due to uneven discharging, the crushing device may take longer to process the waste with a larger accumulation, thereby reducing the overall production efficiency. Content of the Utility Model
[0005] The purpose of the utility model is to provide a polyamide waste recycling and crushing device, aiming to solve the problem that in the prior art, when the above-mentioned device is in use and the crushing device discharges materials through the discharge hopper, there is a lack of an effective material leveling device. This leads to uneven discharging, which may further affect the efficiency and quality of subsequent processes. Specifically, due to uneven discharging, the crushing device may take longer to process the waste with a larger accumulation, thereby reducing the overall production efficiency.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A polyamide waste recycling and crushing device includes a crushing box and crushing rollers assembled inside the crushing box. A support is installed at the bottom end of the crushing box, and a discharge hopper is connected to the bottom end of the crushing box. A baffle is inserted inside the discharge hopper. A "triangle"-shaped groove is formed on the inner side wall of the discharge hopper. Fixing blocks are installed on both sides of the discharge hopper. A threaded rod is threadedly connected through the surface of the fixing block. One end of the threaded rod is connected to a handle, and the other end of the threaded rod is connected to a convex block. Docking blocks are installed on the inner side walls at both ends of the baffle.
[0007] As a preferred embodiment of the polyamide waste recycling and crushing device of the utility model, the convex block is assembled inside the docking block, and a "convex"-shaped opening is formed inside the docking block.
[0008] As a preferred embodiment of the polyamide waste recycling and crushing device of the utility model, the threaded rod forms a rotational connection between the convex block and the docking block.
[0009] In a preferred embodiment of the polyamide waste recycling and crushing device of this utility model, the baffle is configured to extend and retract via a threaded rod and the discharge hopper.

[0021] 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.
[0022] Example 1
[0023] Please see Figure 1-4 The present invention provides the following technical solution: a polyamide waste recycling and crushing device, including a crushing box 1 and a crushing roller 3 assembled inside the crushing box 1, a support 2 installed at the bottom end of the crushing box 1, a discharge hopper 4 connected to the bottom end of the crushing box 1, a baffle 5 inserted inside the discharge hopper 4, a triangular groove 6 opened on the inner side wall of the discharge hopper 4, fixing blocks 8 installed on both sides of the discharge hopper 4, a threaded rod 9 threaded through the surface of the fixing block 8, a handle 7 connected to one end of the threaded rod 9, a protrusion 10 connected to the other end of the threaded rod 9, and connecting blocks 11 installed on the inner side walls of both ends of the baffle 5.
[0024] In a preferred embodiment: the protrusion 10 is assembled inside the mating block 11, and the mating block 11 has a protruding opening inside.
[0025] In a preferred embodiment, the threaded rod 9 is rotatably connected to the mating block 11 via the protrusion 10.
[0026] In a preferred embodiment: the baffle 5 is connected to the discharge hopper 4 via a threaded rod 9 to form a threaded telescopic movement.
[0027] In this embodiment, the recycled polyamide waste is first fed into the top of the crushing chamber 1. The waste is then smoothly guided along the guide plate inside the crushing chamber 1 to between two opposing rotating crushing rollers 3. These two crushing rollers 3 are driven by two motors, rotating clockwise and counterclockwise respectively, working together to effectively crush the polyamide waste. The crushed waste continues to flow along the path of the crushing chamber 1 and is finally discharged smoothly from the discharge hopper 4.
[0028] In addition, the operator can manually hold handle 7 and rotate threaded rod 9, which then moves smoothly along the surface of fixed block 8. During this process, threaded rod 9 drives protrusion 10 to rotate flexibly inside mating block 11, thereby pushing baffle 5 to move and adjusting its degree of obstruction to discharge hopper 4. Through this design, the internal opening size of discharge hopper 4 can be precisely adjusted, thereby effectively controlling the discharge amount, ensuring uniform feeding, avoiding the problem of waste accumulation caused by uneven discharge, and significantly improving overall production efficiency.
[0029] It is worth noting that the inner wall of the discharge hopper 4 is designed with a "triangular" groove 6. This ingenious design effectively prevents the crushed polyamide waste from getting stuck in the groove 6 during the feeding process, thus affecting the normal opening function of the baffle 5.
[0030] Example 2
[0031] Please see Figure 1-4 A filter box 12 is installed on the side wall support plate of the crushing box 1, and an exhaust fan 13 is installed on the side wall support plate of the crushing box 1. A pipe 14 connects the exhaust fan 13 and the filter box 12.
[0032] In a preferred embodiment: a filter box 15 is installed on the inner side wall of the crushing box 1, and the filter box 15 is made of metal.
[0033] In a preferred embodiment, the pipe 14 extends into the interior of the crushing chamber 1 and is located within the filter box 15.
[0034] In this embodiment, as described in Embodiment 1 above, while the recycled polyamide waste is being fed into the top of the crushing box 1, the operator turns on the power to the exhaust fan 13, which then starts and generates suction. This suction is efficiently transferred to the inside of the filter box 15 through the filter box 12 and the pipe 14. The surface of the filter box 15 has filter holes, which ensure unobstructed suction while also allowing effective absorption of dust generated during the waste feeding process. The dust penetrates the filter holes into the filter box 15 and is then guided along the pipe 14 into the filter box 12, where the filtration device (i.e., a filter screen or activated carbon) inside the filter box 12 filters the dust. The filtered gas is then safely discharged through the exhaust end of the exhaust fan 13. This significantly reduces the risk of dust generation and ensures a clean and safe working environment.
[0035] Of particular note is the use of filter box 15. Its main purpose is to prevent recycled polyamide waste from falling directly onto pipe 14 when it is fed from the top of the crushing box 1, thus avoiding potential damage to pipe 14. Therefore, filter box 15 plays a crucial role in protecting pipe 14, while its unique design also ensures that dust can enter pipe 14 smoothly and without obstruction.
[0036] Subsequently, the filter box 12 is connected to the pipe 14 via a flange connection. The filter device inside the pipe 14 needs to be replaced to facilitate disassembly and reassembly of the connection with the pipe 14. Then, a new filter box 12 is installed for use.
[0037] Finally, the suction force generated by the exhaust fan 13 is less than the weight of the recycled polyamide waste, while still being able to effectively absorb dust.
[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is 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.
