Description

Technical Field

[0001] This utility model relates to the field of plastic recycling, and in particular to a crusher for recycling waste plastics. Background Technology

[0002] Plastics, as an important industrial raw material, play an indispensable role in our daily lives. With its lightweight, durability, waterproofing, and insulation properties, plastics are widely used in various fields. However, while bringing convenience, their environmental pollution cannot be ignored. To reduce this pollution, waste plastics are typically recycled. This recycling process requires the use of crushers, which are devices driven by motors that rotate crushing rollers to pulverize waste plastics. These rollers break down waste plastics into smaller pieces, facilitating subsequent recycling.

[0003] According to the existing Chinese patent application publication number "CN220428973U", a crushing and washing integrated machine for recycling waste plastics is described as follows: by rotating two partitions, the two partitions are made to be in a horizontal state. At this time, the rubber layer between the two partitions is compressed, which seals the contact position of the two partitions. At the same time, the top of the partitions is tightly attached to the sealing block, which separates and seals the space above and below the partitions. When water is injected into the processing tank, it can prevent water vapor from entering the top of the partitions and reduce the rusting of the crushing rollers.

[0004] However, in actual use, when the partition rotates downwards and tilts to discharge waste plastic, the waste plastic will fall into the water in the washing chamber. The plastic will splash water as it enters the water. Since the partition has not yet started to tilt upwards, the water splashes onto the partition. Because the waste plastic has been crushed into small pieces by the crushing roller, these small pieces tend to adhere to the water on the partition. As a result, relying solely on the tilting of the partition is insufficient to discharge all the plastic.

[0005] Therefore, it is necessary to provide a new crusher for waste plastic recycling to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a crusher for recycling waste plastics.

[0007] This utility model provides a crusher for recycling waste plastics, including a crushing box, which contains a crushing chamber and a washing chamber. The crushing chamber is located above the washing chamber. A crushing roller is rotatably connected inside the crushing chamber. Partitions are rotatably connected to both sides of the inner wall of the crushing box, and the partitions are located between the crushing chamber and the washing chamber. Mounting plates are fixedly connected to both sides of the bottom of the partitions. An inclined guide groove is opened on the side of the mounting plate near the edge of the partition on the same side. Limiting openings are opened on both sides of the partitions. A sleeve is slidably connected to the limiting opening. A mounting base is slidably connected to the bottom of the sleeve. A pulley is rotatably connected to the side of the mounting base near the mounting plate on the same side, and the pulley is located in the guide groove of the mounting plate on the same side. A counterweight is fixedly connected to the bottom of the mounting base by a traction rope. A baffle is fixedly connected between the tops of the sleeves.

[0008] Preferably, a connecting rod is rotatably connected to both sides of one side of the crushing box. The two connecting rods have different lengths, and each connecting rod is fixedly connected to one end of the rotating shaft of the partition on the same side. A pulley A is fixedly connected to the side of the connecting rod away from the crushing box.

[0009] Preferably, an installation tube is fixedly connected to the side of the crushing box near the connecting rod, and the installation tube is located between the two connecting rods. A pulley B is rotatably connected to the end of the installation tube away from the crushing box, and a pulley C is rotatably connected to the end of the installation tube near the crushing box. A helical gear A is fixedly connected to the side of pulley B near pulley C, and a helical gear B is fixedly connected to the side of pulley C near pulley B. A helical gear C is rotatably connected to one side of the inner wall of the installation tube, and the helical gear C meshes with both helical gear A and helical gear B. A transmission belt is provided between pulley B and pulley C and the corresponding pulley A. A handle is rotatably connected to the end of the installation tube away from the crushing box, and the handle is fixedly connected to one end of the shaft of pulley B.

[0010] Preferably, a spring is fixedly connected between the inner top wall of the sleeve and the top of the mounting base on the same side, and sealing diaphragms are fixedly connected to both sides of the inner wall of the limiting port, and magnetic strips are fixedly connected to the side of the two sealing diaphragms in the limiting port that are in contact with each other.

[0011] Preferably, a stirring paddle is rotatably connected inside the cleaning chamber, and a motor B for driving the stirring paddle to rotate is fixedly connected to one side of the crushing box.

[0012] Preferably, a motor A is fixedly connected to one side of the crushing box, and the output end of the motor A is fixedly connected to one end of the crushing roller.

[0013] Preferably, a water inlet pipe is fixedly connected to one side of the crushing box, and the water inlet pipe is connected to the washing chamber. A material discharge pipe is provided at the bottom of the crushing box, and support legs are fixedly connected to the four corners of the bottom of the crushing box.

[0014] Compared with related technologies, the crusher for recycling waste plastics provided by this utility model has the following beneficial effects:

[0015] 1. When the partition plate is tilted, the mounting plate tilts along with it. At this time, the pulley will slide along the guide groove, causing the baffle to move from one side of the partition plate close to the inner wall of the crushing chamber to the other side. During this process, the baffle can push small pieces of plastic that are adsorbed on the partition plate due to water stains into the cleaning chamber. When the partition plate returns to its normal position, since the guide groove is tilted towards the inner wall of the crushing chamber, the pulley can quickly move back to its original position along the guide groove through the counterweight effect, so as to continue to push the plastic on the subsequent partition plate. This avoids the problem that small pieces of plastic are easily adsorbed on the partition plate after encountering water, which would prevent the device from being able to discharge all the plastic by simply tilting the partition plate. This effectively improves the auxiliary function of the device for plastic discharge.

[0016] 2. By rotating the handle, this utility model can drive the pulley B to rotate, and at the same time, through the cooperation of helical gears A, B and C, drive the pulley C to rotate in the opposite direction. Then, through the transmission effect of the transmission belt, the opening and closing of the two partitions can be completed by rotating a single handle, which further improves the auxiliary function of the device for the operator.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 6 This utility model provides a crusher for recycling waste plastics. The crusher includes a crushing box 1, which is provided with a crushing chamber 11 and a washing chamber 12. The crushing chamber 11 is located above the washing chamber 12. A water inlet pipe 13 is fixedly connected to one side of the crushing box 1 and is connected to the washing chamber 12. A material discharge pipe is provided at the bottom of the crushing box 1, and support legs are fixedly connected to the four corners of the bottom of the crushing box 1.

[0027] A crushing roller 2 is rotatably connected inside the crushing chamber 11, and a motor A21 is fixedly connected to one side of the crushing box 1, with the output end of the motor A21 fixedly connected to one end of the crushing roller 2.

[0028] It should be noted that: the top of the crushing box 1 is equipped with a feeding hopper, which is connected to the crushing chamber 11. Waste plastic can be directly put into the feeding hopper, and then the waste plastic will automatically enter the crushing roller 2 and be crushed by the crushing roller 2. Clean water can be injected into the cleaning chamber 12 through the water inlet pipe 13 to facilitate the subsequent cleaning of the crushed waste plastic.

[0029] It should be noted that: by turning on motor A21, motor A21 drives the crushing roller 2 to rotate, and the rotating crushing roller 2 can crush waste plastic.

[0030] In the embodiments of this utility model, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 Both sides of the inner wall of the crushing chamber 1 are rotatably connected to partition plates 3, and the partition plates 3 are located between the crushing chamber 11 and the washing chamber 12. Mounting plates 31 are fixedly connected to both sides of the bottom of the partition plates 3. An inclined guide groove 311 is provided on the side of the mounting plate 31 closest to the edge of the partition plate 3 on the same side. Limiting openings 32 are provided on both sides of the partition plates 3. A sleeve 33 is slidably connected within the limiting opening 32. A mounting base 331 is slidably connected to the bottom of the sleeve 33. A rotating guide groove 311 is provided on the side of the mounting base 33 closest to the mounting plate 31 on the same side. A pulley 333 is dynamically connected and is located in the guide groove 311 of the mounting plate 31 on the same side. A counterweight 334 is fixedly connected to the bottom of the mounting base 331 by a traction rope. A baffle 34 is fixedly connected between the tops of the sleeves 33. A spring 332 is fixedly connected between the inner top wall of the sleeve 33 and the top of the mounting base 331 on the same side. Sealing diaphragms 35 are fixedly connected to both sides of the inner wall of the limiting port 32. Magnetic strips are fixedly connected to the side of the two sealing diaphragms 35 in the limiting port 32 that are in contact with each other.

[0031] It should be noted that when the partition 3 is tilted, the mounting plate 31 tilts accordingly. At this time, the pulley 333 will slide along the guide groove 311, driving the baffle 34 from one side of the partition 3 closest to the inner wall of the crushing chamber 1 to the other side. During this process, the baffle 34 can push small pieces of plastic adsorbed on the partition 3 due to water stains into the cleaning chamber 12. When the partition 3 returns to its normal position, since the guide groove 311 is tilted towards the inner wall of the crushing chamber 1, the counterweight 334 lowers the center of gravity of the mounting base 331, allowing the pulley 333 to quickly move back to its original position along the guide groove 311, facilitating the continued pushing of plastic on the partition 3. During the movement of the sleeve 33, since the guide groove 311 is tilted, each part of the guide groove 311 is located in relation to... The distances between the partitions 3 are different. At this time, the telescopic sleeve 33 and the mounting base 331, together with the stretchable and elastic characteristics of the spring 332, allow the sleeve 33 to slide stably along the guide groove 311 without changing the distance between itself and the guide groove 311, and drive the baffle 34 to move. At the same time, the sealing diaphragm 35 and the magnetic strip can seal the limiting port 32 to prevent water vapor in the cleaning chamber 12 from entering the crushing chamber 11 through the limiting port 32. With the cooperation of the magnetic strips on the two sealing diaphragms 35, when the sleeve 33 moves along the limiting port 32, the sleeve 33 can separate the magnetic strips. After the sleeve 33 moves, the magnetic strips will attract each other, so that the two sealing diaphragms 35 stick together and seal the limiting port 32.

[0032] In the embodiments of this utility model, please refer to Figure 1 , Figure 3 and Figure 6Two connecting rods 4 are rotatably connected to both sides of one side of the crushing box 1. The two connecting rods 4 are of different lengths, and each connecting rod 4 is fixedly connected to one end of the rotating shaft of the partition 3 on the same side. A pulley A41 is fixedly connected to the side of the connecting rods 4 away from the crushing box 1. An installation pipe 5 is fixedly connected to the side of the crushing box 1 near the connecting rods 4, and the installation pipe 5 is located between the two connecting rods 4. A pulley B51 is rotatably connected to the end of the installation pipe 5 away from the crushing box 1, and a pulley C52 is rotatably connected to the end of the installation pipe 5 near the crushing box 1. The pulley B51 is close to... A helical gear A53 is fixedly connected to the side of the pulley C52, and a helical gear B54 is fixedly connected to the side of the pulley C52 near the pulley B51. A helical gear C55 is rotatably connected to the inner wall of the mounting tube 5, and the helical gear C55 meshes with the helical gears A53 and B54 respectively. A transmission belt 56 is provided between the pulleys B51 and C52 and the corresponding pulleys A41. A handle 57 is rotatably connected to the end of the mounting tube 5 away from the crushing box 1, and the handle 57 is fixedly connected to one end of the shaft of the pulley B51.

[0033] It should be noted that: when the handle 57 is turned, it drives the pulley B51 to rotate. At this time, the pulley B51 drives the helical gear A53 to rotate, and the helical gear A53 drives the helical gear C55 to rotate. The helical gear C55 then drives the helical gear B54 to rotate in the opposite direction to the helical gear A53. The helical gear B54 drives the pulley C52 to rotate. At this time, the pulleys B51 and C52 rotate in opposite directions. Combined with the transmission effect of the drive belt 56, the two partitions 3 on both sides of the crushing box 1 can be operated in opposite directions at the same time when the handle 57 is turned, that is, the two partitions 3 can be rotated downwards or raised simultaneously.

[0034] In the embodiments of this utility model, please refer to Figure 2 A stirring paddle 6 is rotatably connected inside the cleaning chamber 12, and a motor B61 for driving the stirring paddle 6 to rotate is fixedly connected to one side of the crushing box 1.

[0035] It should be noted that when the waste plastic is crushed and discharged into the washing chamber 12, the motor B61 is started to drive the agitator 6 to rotate. Together with the clean water in the washing chamber 12, the washing of the waste plastic can be completed.

[0036] The working principle of the crusher for recycling waste plastics provided by this utility model is as follows:

[0037] First, install the device in the designated location, then power it on and inject an appropriate amount of clean water into the cleaning chamber 12 through the water inlet pipe 13. Then, the waste plastic crushing work can be carried out.

[0038] Waste plastic is placed into the feed hopper and automatically enters the crushing roller 2. At this point, motor A21 is turned on, driving the crushing roller 2 to rotate. The rotating crushing roller 2 crushes the waste plastic. After crushing, the waste plastic falls onto the partition 3 and is piled up. When a certain amount of waste plastic has accumulated on the partition 3, handle 57 is turned, causing pulley B51 to rotate. Pulley B51 then drives helical gear A53 to rotate, which in turn drives helical gear C55. Helical gear C55 then drives helical gear B54 to rotate in the opposite direction to helical gear A53. Helical gear B54 then drives pulley C52... When the pulley is turned, the pulleys B51 and C52 rotate in opposite directions. Combined with the transmission effect of the transmission belt 56, when the handle 57 is turned, the two partitions 3 rotate downwards simultaneously, connecting the crushing chamber 11 and the cleaning chamber 12. At this time, the waste plastic piled on the partition 3 will fall into the cleaning chamber 12 along the inclined partition 3. When the partition 3 is inclined, the mounting plate 31 also tilts. At this time, the pulley 333 will slide along the guide groove 311 and drive the baffle 34 from one side of the partition 3 closest to the inner wall of the crushing box 1 to the other side. During this process, the baffle 34 can push the small pieces of plastic that are adsorbed on the partition 3 due to water stains into the cleaning chamber 12.

[0039] Then, by turning the handle 57 in the opposite direction, the two partitions 3 can be raised simultaneously. At this time, the crushing chamber 11 and the cleaning chamber 12 can be separated by the cooperation of the two partitions 3. When the partitions 3 are returned to the center, since the guide groove 311 is inclined towards the inner wall of the crushing box 1, the center of gravity of the mounting base 331 is lowered by the counterweight 334, so that the pulley 333 can quickly move to the original position along the guide groove 311, which is convenient for continuing to push the plastic on the subsequent partitions 3.

[0040] Finally, start motor B61 to drive the agitator 6 to rotate. Together with the clean water in the cleaning chamber 12, the waste plastic can be cleaned. After cleaning, the cleaned waste plastic can be discharged through the discharge pipe at the bottom of the crushing box 1.

[0041] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0042] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
