Description

Technical Field

[0001] The present invention belongs to the technical field of plastic bottle recycling and treatment, and specifically relates to a waste plastic bottle crushing and recycling device. Background Art

[0002] Plastic products are widely used in various fields, from daily necessities to industrial products, and are almost everywhere. However, with the continuous increase in plastic consumption, the problem of waste plastics has become increasingly prominent. Especially, the daily output of plastic bottles for holding mineral water and beverages is the largest. Therefore, for the recycling of plastic bottles, a crushing and recycling device is usually used to crush them, and then they are heated by a heating device to melt into a plastic solution, and at the same time, plastic particles are manufactured by a granulating device for recycling.

[0003] A patent with the publication number CN118024462B discloses a waste plastic barrel crushing device. The device processes a V-shaped groove at the end of the crushing teeth, changing the contact stress point of the crushing teeth to two sharp ends of the teeth, enabling the crushing teeth to easily pierce and bite the barrel wall of the waste plastic barrel, avoiding the rotation of the waste plastic barrel, ensuring the crushing effect of the waste plastic barrel. The crushing teeth are installed and fixed by bolts, facilitating the removal of the crushing teeth for grinding treatment to ensure the sharpness of the crushing teeth for crushing the waste plastic barrel. The T-shaped moving part is driven by an electric cylinder to move. When the electric cylinder drives the T-shaped moving part to move leftward, the T-shaped moving part and the movable switching frame are stressed by the inclined plane. The T-shaped moving part drives the movable switching frame to move outward, and the spring is gradually compressed, causing the driven gear to mesh with the driving gear B, and the second motor is started while the first motor is in the stopped state. When the electric cylinder drives the T-shaped moving part to move leftward, the movable switching frame moves inward to reset under the influence of the spring thrust, causing the driven gear to mesh with the driving gear A, and the first motor is started while the second motor is in the stopped state. The T-shaped moving part is driven by the electric cylinder to move once every six hours, effectively avoiding overheating caused by a single motor running continuously for a long time, affecting its service life, and ensuring the service life and operating stability of the motor.

[0004] The above solution still has some problems in actual application. By using the crushing teeth designed with V-shaped grooves to bite and penetrate the plastic bottle for crushing, however, if the plastic barrel or bottle is larger than two crushing rollers and the barrel or bottle body is smooth, the crushing teeth will be difficult to effectively bite the barrel or bottle body, resulting in the barrel or bottle rolling between the two crushing rollers and being difficult to be torn and crushed. Especially for the crushing teeth designed with V-shaped grooves, after crushing the plastic, the remaining plastic will wind around the outside of the crushing rollers and the crushing teeth, and excessive accumulation will affect the penetration effect of the crushing teeth and reduce the tearing and crushing efficiency of the plastic bottle.

[0005] Therefore, the present invention provides a waste plastic bottle crushing and recycling device. Summary of the Invention

A plurality of groups of crushing teeth are arranged in a ring on the outer part of the rotating roller, and the crushing teeth on the outer parts of the two rotating rollers are arranged in a staggered manner for quickly tearing the plastic bottle; A plurality of grooves are formed in the outer part of the rotating roller, and a plurality of groups of L-shaped crushing knives are arranged in a ring on the outer part of the rotating roller; Tooth openings are evenly arranged on the cutting edge side of the L-shaped crushing knife for cutting large plastic bottles. At the same time, the tooth openings of the L-shaped crushing knife can press the large plastic bottle into the space between the two rotating rollers; Brushes are arranged on both sides of the L-shaped crushing knife, and the brushes are used to brush and clean the residue after the plastic bottle is broken on the outer part of the rotating roller.

[0008] Preferably, a slot is formed at one end of the rotating roller, and a first gear and a second gear are installed in the inner cavity of the slot through which one end of the rotating roller penetrates the crushing box.

[0009] Preferably, the first gear is meshed with a transmission gear, the second gear is meshed with a driven gear, the transmission gear and the driven gear are meshed with each other, and the transmission gear and the driven gear are rotatably connected to the crushing box.

[0010] Preferably, a protective cover is installed on one side of the crushing box, a fixing frame is installed at the upper end of the support frame, a servo motor is installed in the inner cavity of the fixing frame, and the output shaft end of the servo motor penetrates the protective cover and is fixedly installed with the transmission gear.

[0011] Preferably, a first pulley is installed outside the output shaft end of the servo motor in the inner cavity of the protective cover, a belt is connected to the outside of the first pulley in a transmission manner, a second pulley is connected to one end of the belt in a transmission manner, and a conveying auger is installed inside the second pulley.

[0012] Preferably, one end of the conveying auger is hollow inside, and a heating rod is installed in the hollow part of the conveying auger to heat and melt the crushed plastic bottle through the heating rod.

[0013] Preferably, a heating cylinder is fixedly connected to the lower end of the crushing box. The inner cavity of the heating cylinder is rotationally installed with a conveying auger. An energized carbon brush is installed at one end of the heating cylinder, and the energized carbon brush is rotationally installed outside the conveying auger.

[0014] Preferably, a granulation plate is installed at one end of the heating cylinder. A plug rod is slidably connected inside the granulation plate, and a cutting blade is installed at one end of the plug rod.

[0015] Preferably, a limiting groove is formed at one end of the conveying auger. A tension spring is fixedly connected to the bottom of the inner cavity of the limiting groove. One end of the tension spring is fixedly connected to a plug rod, and the plug rod is inserted and installed in the limiting groove.

[0016] Preferably, a distribution box is installed on the upper end surface of the support frame, and universal wheels are arranged at the lower end of the support frame.

[0017] The beneficial effects of the present invention are as follows: 1. For the waste plastic bottle crushing and recycling device of the present invention, it enters the material guiding cover through the funnel. At the same time, the plastic bottles are guided into the crushing box by the material guiding cover. Then, the driving rotating column drives the rotating roller to rotate, and then the plastic bottles are shredded by the crushing teeth. When recycling large plastic bottles, the L-shaped crushing knife is driven to rotate by the rotating roller, and the L-shaped crushing knife cuts and crushes the large plastic bottles. For relatively smooth large plastic bottles, the L-shaped crushing knife can press the plastic bottles and push them between the two rotating rollers, so that the rotating roller can use the crushing teeth to shred and recycle the plastic bottles. When the L-shaped crushing knife rotates with the rotating roller, it will slide into the inner cavity of the groove. At the same time, brushes are arranged on both sides of the L-shaped crushing knife. Therefore, during the process of the L-shaped crushing knife sliding into the inner cavity of the groove, the plastic bottle debris remaining on the outer package of the rotating roller and the crushing teeth is brushed and cleaned, so as to facilitate the discharged and recycled plastic bottles after crushing from the crushing box, solving the problem that the existing recycling device cannot easily pierce and bite the barrel wall of the waste plastic barrel, which is likely to cause the rolling of the waste plastic barrel.

[0018] 2. The waste plastic bottle crushing and recycling device described in the present invention conveys the plastic bottle fragments after heating and melting to the tail of the heating cylinder through a conveying auger. Then, with the continuous rotation of the conveying auger, the melted plastic bottle solution will be extruded at the tail of the heating cylinder by the conveying auger and extruded through a granulation plate. At the same time, the conveying auger drives the insertion rod to rotate, and the insertion rod drives the cutting blade to rotate, so that the cutting blade cuts the plastic bottle solution extruded by the granulation plate into particles, thus solving the problem that when the existing waste plastic bottle crushing and recycling device recycles waste plastic bottles, it usually uses a crushing roller to tear and crush the waste plastic bottles, and then needs to use a cloth bag to recycle the crushed plastic bottle fragments, and then pour the recycled plastic bottle fragments into a heating device to heat and melt them into a solution, which not only affects the recycling efficiency of plastic bottles and is cumbersome to operate, but also when the plastic bottles are crushed and recycled, they cannot be accurately discharged into the cloth bag for collection, resulting in being scattered everywhere, affecting the convenience of plastic bottle crushing and recycling.

DETAILED DESCRIPTION OF THE INVENTION

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] Embodiment 1: As Figures 1 to 7 shown, a waste plastic bottle crushing and recycling device described in an embodiment of the present invention includes a support frame 1. A crushing box 2 is installed at the upper end of the support frame 1. One side of the crushing box 2 is fixedly connected with a hinge 13, and one end of the hinge 13 is fixedly connected with a feeding cover 3. A funnel 4 is arranged on one side of the upper end of the feeding cover 3. A plastic bottle recycling component is arranged in the inner cavity of the crushing box 2; And the plastic bottle recycling component includes two rotating columns 14 rotatably connected in the inner cavity of the crushing box 2. Rotating rollers 11 are installed on the outer parts of the two rotating columns 14. A plurality of groups of crushing teeth 16 are arranged in a ring on the outer part of the rotating roller 11. The crushing teeth 16 on the outer parts of the two rotating rollers 11 are arranged in a staggered manner to quickly tear the plastic bottle; A plurality of grooves 17 are formed on the outer part of the rotating roller 11. A plurality of groups of L-shaped crushing knives 18 are arranged in a ring on the outer part of the rotating roller 11; Tooth openings are evenly arranged on the edge of the cutting edge of the L-shaped crushing knife 18 for cutting large plastic bottles. At the same time, the tooth openings of the L-shaped crushing knife 18 can press the large plastic bottle into the space between the two rotating rollers 11; Brushes are arranged on both sides of the L-shaped crushing knife 18, and the brushes are used to brush and clean the residues after the plastic bottles outside the rotating roller 11 are broken.

[0023] Specifically, in the prior art, waste plastic bottles are usually put into the crushing box, and at the same time, two crushing rollers in the crushing box are used to tear and crush the waste plastic bottles. However, after the crushing rollers tear and crush the plastic bottles, the broken plastic bottle fragments will remain on the outside of the crushing rollers. If not cleaned, it will affect the subsequent crushing efficiency of waste plastic bottles. Moreover, when crushing large plastic bottles or smooth plastic bottles, since the smooth plastic bottles will rotate between the two crushing rollers, it is difficult for the crushing rollers to tear and crush the plastic bottles, affecting the recycling efficiency of plastic bottles; When the present invention recycles plastic bottles, the plastic bottles are put into the funnel 4 and enter the material guiding cover 3 through the funnel 4. At the same time, the material guiding cover 3 is used to guide the plastic bottles into the crushing box 2. The setting of the material guiding cover 3 can prevent the plastic bottles from splashing out of the crushing box 2 after being broken. Then, the rotating column 14 is driven to rotate, and the rotating column 14 drives the rotating roller 11 to rotate. Furthermore, the rotating roller 11 uses the external crushing teeth 16 to tear the plastic bottles during rotation. When recycling large plastic bottles, the L-shaped crushing knife 18 is driven to rotate by the rotating roller 11, and the L-shaped crushing knife 18 cuts and crushes the large plastic bottles. When recycling relatively smooth large plastic bottles, the L-shaped crushing knife 18 can press the plastic bottles and push them between the two rotating rollers 11. Furthermore, the rotating roller 11 can use the crushing teeth 16 to tear and recycle the plastic bottles. When the L-shaped crushing knife 18 rotates with the rotating roller 11, it will slide into the inner cavity of the groove 17. At the same time, brushes are arranged on both sides of the L-shaped crushing knife 18. Therefore, during the process of the L-shaped crushing knife 18 sliding into the inner cavity of the groove 17, the plastic bottle debris remaining on the outside of the rotating roller 11 and the crushing teeth 16 is brushed and cleaned, so that the crushed plastic bottles can be discharged from the crushing box 2 for recycling, thus solving the above problems.

[0024] As Figure 1 , Figure 4 and Figure 5 shown, a slot 15 is opened at one end of the rotating roller 11. One end of the rotating roller 11 penetrates through the crushing box 2, and a first gear 25 and a second gear 27 are installed in the inner cavity of the slot 15.

[0025] As Figure 1 , Figure 4 and Figure 5 shown, the first gear 25 is meshed with a transmission gear 24, the second gear 27 is meshed with a driven gear 26, the transmission gear 24 and the driven gear 26 are meshed with each other, and the transmission gear 24 and the driven gear 26 are rotationally connected to the crushing box 2.

[0026] As Figure 1 , Figure 4 and Figure 5 shown, a protective cover 6 is installed on one side of the crushing box 2. A fixing frame 12 is installed at the upper end of the support frame 1. A servo motor 7 is installed in the inner cavity of the fixing frame 12. The output shaft end of the servo motor 7 penetrates through the protective cover 6 and is fixedly installed with the transmission gear 24.

[0027] Specifically, when recycling plastic bottles, the servo motor 7 is started to drive the transmission gear 24 to rotate, and the transmission gear 24 meshes with and drives the driven gear 26 to rotate. At the same time, the transmission gear 24 and the driven gear 26 mesh with and drive the first gear 25 and the second gear 27 to rotate, thereby driving the two rotating columns 14 to rotate, and at the same time driving the rotating rollers 11 to rotate in opposite directions. Multiple groups of crushing teeth 16 are arranged outside the rotating rollers 11. Therefore, the crushing teeth 16 can be used to quickly tear and recycle plastic bottles. Moreover, the first gear 25 and the second gear 27 are inserted and installed on the rotating columns 14 through the slots 15. Therefore, it is convenient to quickly disassemble and clean the rotating columns 14 from the crushing box 2, preventing the situation that when the rotating rollers 11 use the crushing teeth 16 to crush and recycle plastic bottles or plastic products of other materials, the crushed plastics are wound around the outside of the rotating rollers 11, resulting in the trouble of difficult quick cleaning.

[0028] As Figure 1 , Figure 4 and Figure 5 shown, a first pulley 28 is installed at the output shaft end of the servo motor 7 outside the inner cavity of the protective cover 6. A belt 29 is connected to the outside of the first pulley 28. One end of the belt 29 is connected to a second pulley 30, and a conveying auger 19 is installed inside the second pulley 30.

[0029] As Figure 2 , Figure 4 and Figure 5 shown, one end of the conveying auger 19 is hollow inside, and a heating rod 32 is installed inside the hollow part of the conveying auger 19. The heating rod 32 is used to heat and melt the crushed plastic bottles throughout the conveying auger 19.

[0030] Specifically, when recycling and processing the crushed plastic bottles, the servo motor 7 is started to drive the first pulley 28 to rotate, and the first pulley 28 drives the belt 29 to rotate. At the same time, the belt 29 drives the second pulley 30 to rotate, thereby driving the conveying auger 19 to agitate and convey the plastic bottle fragments flowing out of the inner cavity of the crushing box 2. During the process of agitating and conveying the plastic bottle fragments by the conveying auger 19, the heating rod 32 is started to heat the conveying auger 19. Therefore, the conveying auger 19 is used to heat and melt the plastic bottle fragments, so that the plastic bottle fragments form a plastic bottle solution after heating. The plastic bottle solution formed after heating has good plasticity, thus facilitating the granulation and recycling of the plastic bottle solution and improving the convenience of plastic bottle recycling.

[0031] Embodiment 2: As Figure 2 , Figure 4 and Figure 5As shown, a heating cylinder 5 is fixedly connected to the lower end of the crushing box 2. The inner cavity of the heating cylinder 5 is rotatably installed with a conveying auger 19. One end of the heating cylinder 5 is internally installed with an energized carbon brush 31, and the energized carbon brush 31 is rotatably installed outside the conveying auger 19.

[0032] As Figure 2 , Figure 4 and Figure 5 shown, a granulating plate 9 is installed at one end of the heating cylinder 5. A plug rod 22 is slidably connected inside the granulating plate 9, and a cutting blade 23 is installed at one end of the plug rod 22.

[0033] Specifically, when driving the conveying auger 19 to agitate and convey the heated and melted plastic bottle fragments, the heated and melted plastic bottle fragments will be conveyed to the tail of the heating cylinder 5. Then, with the continuous agitation and conveying of the conveying auger 19, the heated and melted plastic bottle solution will be extruded by the conveying auger 19 at the tail of the heating cylinder 5 and extruded through the granulating plate 9. At the same time, the conveying auger 19 drives the plug rod 22 to rotate, and the plug rod 22 drives the cutting blade 23 to rotate, so that the cutting blade 23 cuts the plastic bottle solution extruded by the granulating plate 9 into particles, thus solving the problem that when the existing waste plastic bottle crushing and recycling device recycles waste plastic bottles, it usually uses a crushing roller to tear and crush the waste plastic bottles. Then, it is necessary to use a cloth bag to recycle the crushed plastic bottle fragments, and then pour the recycled plastic bottle fragments into a heating device to heat and melt them into a melt. This not only affects the recycling efficiency of plastic bottles and the operation is cumbersome, but also when the plastic bottles are crushed and recycled, they cannot be accurately discharged into the cloth bag for collection, resulting in scattered everywhere, affecting the convenience of plastic bottle crushing and recycling.

[0034] As Figure 1 , Figure 4 and Figure 5 shown, a limiting groove 20 is opened at one end of the conveying auger 19. A tension spring 21 is fixedly connected to the bottom of the inner cavity of the limiting groove 20. One end of the tension spring 21 is fixedly connected to the plug rod 22, and the plug rod 22 is inserted and installed in the limiting groove 20.

[0035] As Figure 1 , Figure 3 and Figure 5 shown, a distribution box 8 is installed on the upper end surface of the support frame 1, and universal wheels 10 are arranged at the lower end of the support frame 1.

[0036] Specifically, when heating and granulating and recycling plastic bottles, the tension spring 21 is used to pull the plug rod 22 to slide into the inner cavity of the limiting groove 20. At the same time, the plug rod 22 pulls the cutting blade 23 to be closely attached to the surface of the granulating plate 9, preventing the cutting blade 23 from being pushed by the plastic bottle solution extruded by the granulating plate 9 during the rotation process, resulting in uneven particle sizes of the plastic bottle solution that is difficult to cut by the cutting blade 23.

[0037] Working principle: Put the plastic bottle into the funnel 4, and it enters the material guiding cover 3 through the funnel 4. At the same time, use the material guiding cover 3 to guide the plastic bottle into the crushing box 2. The setting of the material guiding cover 3 can prevent the plastic bottle from splashing out of the crushing box 2 after being broken. Then drive the rotating column 14 to rotate, and make the rotating column 14 drive the rotating roller 11 to rotate. Furthermore, the rotating roller 11 uses the external crushing teeth 16 to tear the plastic bottle during rotation. When recycling large plastic bottles, drive the L-shaped crushing knife 18 to rotate by the rotating roller 11, and the L-shaped crushing knife 18 cuts and crushes the large plastic bottle. When recycling relatively smooth large plastic bottles, the L-shaped crushing knife 18 can press the plastic bottle and push it between the two rotating rollers 11. Furthermore, the rotating roller 11 can use the crushing teeth 16 to tear and recycle the plastic bottle. When the L-shaped crushing knife 18 rotates with the rotating roller 11, it will slide into the inner cavity of the groove 17. At the same time, brushes are arranged on both sides of the L-shaped crushing knife 18. Therefore, during the process of the L-shaped crushing knife 18 sliding into the inner cavity of the groove 17, it brushes and cleans the plastic bottle debris remaining on the outside of the rotating roller 11 and the crushing teeth 16, so as to facilitate the discharged and recycled plastic bottles from the crushing box 2; When recycling the crushed plastic bottles, start the servo motor 7 to drive the first pulley 28 to rotate, and make the first pulley 28 drive the belt 29 to rotate. At the same time, the belt 29 drives the second pulley 30 to rotate, and then drives the conveying auger 19 to agitate and convey the plastic bottle fragments flowing out of the inner cavity of the crushing box 2. During the process of using the conveying auger 19 to agitate and convey the plastic bottle fragments, start the heating rod 32 to heat the conveying auger 19. Furthermore, use the conveying auger 19 to heat and melt the plastic bottle fragments, so that the plastic bottle fragments form a plastic bottle solution after heating. The plastic bottle solution formed after heating has good plasticity; When driving the conveying auger 19 to agitate and convey the heated and melted plastic bottle fragments, the heated and melted plastic bottle fragments will be conveyed to the tail of the heating cylinder 5. Then, with the continuous agitation and conveying of the conveying auger 19, the heated and melted plastic bottle solution will be extruded by the conveying auger 19 at the tail of the heating cylinder 5 and extruded through the granulating plate 9. At the same time, the conveying auger 19 drives the insertion rod 22 to rotate, and the insertion rod 22 drives the cutting blade 23 to rotate. Furthermore, the cutting blade 23 cuts the plastic bottle solution extruded by the granulating plate 9 into particles.
