Description

Technical Field

[0001] This utility model belongs to the field of crusher technology, specifically a PET bottle recycling crusher. Background Technology

[0002] PET bottle recycling crushers are key equipment in the PET bottle recycling process. Their main function is to crush recycled waste PET bottles by cutting them into uniformly sized fragments using high-speed rotating blades. This process effectively reduces the volume of PET bottles, facilitating subsequent recycling processes such as cleaning, drying, and melting. At the same time, the crushing process can also initially separate some impurities, improving the purity and quality of the recycled raw materials and laying the foundation for the recycling of PET bottles.

[0003] The PET bottle recycling crusher uses a combination of a rotating blade and a fixed blade. Its shearing force mainly relies on the relative motion of the single set of blades. The cutting of PET bottles is mostly unidirectional tearing. When facing hard bottles or stacked materials, jamming is likely to occur, and the material cannot be crushed quickly, increasing the processing time. Therefore, the combination of a single rotating blade and a fixed blade is difficult to form efficient shearing, resulting in low crushing efficiency. Moreover, the crushing and heat dissipation systems often operate independently, making it impossible to achieve synchronous crushing and heat dissipation. Start-up and shutdown require individual operation, increasing the frequency of manual intervention and reducing the overall continuity and automation of the equipment, making it difficult to meet the needs of efficient recycling. Therefore, this application proposes a PET bottle recycling crusher. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a PET bottle recycling crusher, which effectively solves the problems of low crushing efficiency and low integration of the crusher.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PET bottle recycling crusher, comprising a crushing cylinder and a crushing mechanism, wherein multiple supports are fixedly installed at the bottom of the crushing cylinder; the crushing mechanism includes a motor fixedly installed above the crushing cylinder, a rotating rod fixedly installed at the output end of the motor, a bevel gear fixedly installed on the rotating rod, a rotating tube rotatably connected to the crushing cylinder, a transmission rod rotatably connected to the crushing cylinder inside the rotating tube, a driven gear fixedly connected to the transmission rod and the rotating tube being sleeved on both the transmission rod and the rotating tube, the driven gear meshing with the bevel gear, and multiple blades fixedly connected to the transmission rod and the rotating tube being sleeved on both the transmission rod and the rotating tube.

[0006] Preferably, the motor is fixedly mounted with multiple fixed columns that are fixedly connected to the crushing cylinder, and the crushing cylinder is fixedly mounted with a feed inlet that penetrates the crushing cylinder.

[0007] Preferably, a first filter plate is slidably connected inside the crushing cylinder and slides against the inner wall of the crushing cylinder, a transmission rod passes through the first filter plate and is rotatably connected to it, and a plurality of fixed plates are fixedly installed inside the crushing cylinder and are arranged opposite to the first filter plate.

[0008] Preferably, a spring is fixedly installed on the fixing plate and the first filter plate, and a vibration motor is fixedly installed on the bottom of the first filter plate.

[0009] Preferably, a second filter plate is fixedly installed inside the crushing cylinder, which is opposite to and below the first filter plate, and the transmission rod passes through the second filter plate and is rotatably connected to it.

[0010] Preferably, a fan is fitted onto the transmission rod and fixedly connected thereto. The fan is located below the second filter plate, and an air outlet that penetrates the crushing cylinder is fixedly installed on the crushing cylinder.

[0011] Preferably, a through-hole is fixedly installed on the crushing cylinder, the through-hole is positioned opposite to the second filter plate, the crushing cylinder is provided with a groove, a baffle is slidably connected in the groove and slides against the inner wall of the groove, and a magnet is fixedly installed in the groove and positioned opposite to the baffle.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a crushing mechanism, and utilizing the cooperation between the motor, bevel gear, driven gear, blades and fan, the blades on the transmission rod and the blades on the rotating tube rotate in opposite directions. The blades rotating in opposite directions simultaneously shear the PET bottles, which can generate greater shearing force and improve the crushing efficiency of the crusher.

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.

[0016] Depend on Figures 1-4 The present invention includes a crushing cylinder 1 and a crushing mechanism. Multiple supports 2 are fixedly installed at the bottom of the crushing cylinder 1, ensuring its stability. The crushing mechanism includes a motor 5 fixedly installed above the crushing cylinder 1. Multiple fixed columns 6, which are fixedly connected to the crushing cylinder 1, are fixedly installed on the motor 5, ensuring the stability of the crushing cylinder 1. An inlet 10 is fixedly installed through the crushing cylinder 1. A through-hole 22 is fixedly installed through the crushing cylinder 1, with the through-hole 22 facing a second filter plate 16. A groove 21 is provided on the crushing cylinder 1. A baffle 3, which slides and abuts against the inner wall of the groove 21, is slidably connected within the groove 21. A magnet 4, which is opposite to the baffle 3, is fixedly installed within the groove 21. A rotating rod 7 is fixedly installed at the output end of the motor 5. A bevel gear 8 is fixedly installed on the rotating rod 7. A rotating tube 11 is rotatably connected to the crushing cylinder 1. A transmission rod 20 is rotatably connected to the crushing cylinder 1 inside the rotating tube 11. A driven gear 9 is fixedly connected to the transmission rod 20 and the rotating tube 11. The driven gear 9 meshes with the bevel gear 8. Multiple blades 12 are fixedly connected to the transmission rod 20 and the rotating tube 11. A fan 17 is fixedly connected to the transmission rod 20. The fan 17 is located below the second filter plate 16. An air outlet 18 is fixedly installed on the crushing cylinder 1. A first filter plate 15 is slidably connected inside the crushing cylinder 1 and slides against the inner wall of the crushing cylinder 1. A transmission rod 20 passes through the first filter plate 15 and is rotatably connected to it. A plurality of fixed plates 13 are fixedly installed inside the crushing cylinder 1 and are arranged opposite to the first filter plate 15. Springs 14 are fixedly installed on the fixed plates 13 and the first filter plate 15. A vibration motor 19 is fixedly installed at the bottom of the first filter plate 15. A second filter plate 16 is fixedly installed inside the crushing cylinder 1 and is arranged opposite to the first filter plate 15 and located below the first filter plate 15. The transmission rod 20 passes through the second filter plate 16 and is rotatably connected to it. During operation, PET bottles are placed into the feed inlet 10 and the motor 5 is turned on. The PET bottles will enter the crushing cylinder 1 through the feed inlet 10. The output end of the motor 5 will drive the rotating rod 7 to rotate, which in turn drives the bevel gear 8 to rotate. The bevel gear 8 will drive the two driven gears 9 that are meshed with it to rotate. The two driven gears 9 rotate in opposite directions, which will drive the transmission rod 20 and the rotating tube 11 to rotate in opposite directions. The transmission rod 20 and the rotating tube 11 will drive the blades 12 that are fixedly connected to the transmission rod 20 and the rotating tube 11 to rotate in opposite directions. The rotation of the blades 12 can shear the PET bottles. The blades 12 on the transmission rod 20 and the blades 12 on the rotating tube 11 rotate in opposite directions. The blades 12 rotating in opposite directions can simultaneously shear the PET bottles, which can generate greater shearing force and improve the crushing efficiency of the crusher. Furthermore, the transmission rod 20 drives the fan 17, which is fixedly connected to it, to rotate. The rotation of the fan 17 drives air to enter the crushing cylinder 1 from the feed port 10. After passing through the blades 12, the air can exchange heat with the blades 12, thereby reducing the temperature of the blades 12 and preventing damage due to overheating. Also, PET bottle fragments cannot pass through the second filter plate 16. The air will pass through the second filter plate 16 and then through the air outlet 18 to flow out of the crushing cylinder 1, thereby improving the heat dissipation efficiency inside the crushing cylinder 1. Moreover, the crushing operation and heat dissipation operation can be carried out simultaneously, improving the integration of the crusher. Simultaneously, the vibration motor 19 is turned on, which drives the first filter plate 15 to vibrate, thereby accelerating the filtration of PET bottle fragments by the first filter plate 15 and preventing the PET bottle fragments from accumulating on the first filter plate 15 and affecting the crushing work of the blade 12. The spring 14 can also prevent the vibration of the first filter plate 15 from affecting the stability of the crushing cylinder 1. After being filtered by the first filter plate 15, the PET bottle fragments will fall on the upper end of the second filter plate 16. When it is necessary to collect the PET bottle fragments, pulling the baffle 3 can move the baffle 3 along the direction of the groove 21, thereby removing the PET bottle fragments from the crushing cylinder 1 and completing the collection of the PET bottle fragments. After the collection is completed, pulling the baffle 3 can cause the baffle 3 to abut against the magnet 4. Since the baffle 3 is a magnetic material, the baffle 3 will be attracted to the magnet 4, thereby ensuring the sealing of the crushing cylinder 1.

[0017] Working principle: During operation, PET bottles are placed into the feed inlet 10 and the motor 5 is turned on. The PET bottles will enter the crushing cylinder 1 through the feed inlet 10. The output end of the motor 5 will drive the rotating rod 7 to rotate, which in turn drives the bevel gear 8 to rotate. The bevel gear 8 will drive the two driven gears 9 meshing with it to rotate. The two driven gears 9 rotate in opposite directions, which will drive the transmission rod 20 and the rotating tube 11 to rotate in opposite directions. The transmission rod 20 and the rotating tube 11 will drive the blades 12, which are fixedly connected to the transmission rod 20 and the rotating tube 11, to rotate in opposite directions. The rotation of the blades 12 can shear the PET bottles. The blades 12 on the transmission rod 20 and the blades 12 on the rotating tube 11 rotate in opposite directions. The blades 12 rotating in opposite directions can simultaneously shear the PET bottles, generating greater shearing force and improving the crushing efficiency of the crusher. Furthermore, the transmission rod 20 drives the fan 17, which is fixedly connected to it, to rotate. The rotation of the fan 17 drives air to enter the crushing cylinder 1 from the feed port 10. After passing through the blades 12, the air can exchange heat with the blades 12, thereby reducing the temperature of the blades 12 and preventing damage due to overheating. Also, PET bottle fragments cannot pass through the second filter plate 16. The air will pass through the second filter plate 16 and then through the air outlet 18 to flow out of the crushing cylinder 1, thereby improving the heat dissipation efficiency inside the crushing cylinder 1. Moreover, the crushing operation and heat dissipation operation can be carried out simultaneously, improving the integration of the crusher. Simultaneously, the vibration motor 19 is turned on, which drives the first filter plate 15 to vibrate, thereby accelerating the filtration of PET bottle fragments by the first filter plate 15 and preventing the PET bottle fragments from accumulating on the first filter plate 15 and affecting the crushing work of the blade 12. The spring 14 can also prevent the vibration of the first filter plate 15 from affecting the stability of the crushing cylinder 1. After being filtered by the first filter plate 15, the PET bottle fragments will fall on the upper end of the second filter plate 16. When it is necessary to collect the PET bottle fragments, pulling the baffle 3 can move the baffle 3 along the direction of the groove 21, thereby removing the PET bottle fragments from the crushing cylinder 1 and completing the collection of the PET bottle fragments. After the collection is completed, pulling the baffle 3 can cause the baffle 3 to abut against the magnet 4. Since the baffle 3 is a magnetic material, the baffle 3 will be attracted to the magnet 4, thereby ensuring the sealing of the crushing cylinder 1.
