Technical Field

[0001] This invention relates to the field of environmental protection equipment technology, and in particular to a roller-type garbage bag breaking and air separation structure. Background Technology

[0002] In the treatment of household waste, garbage bags typically contain various types of waste, necessitating the breaking of the bags to allow the waste to escape. This process requires the use of a roller-type garbage bag breaking and air-separation structure. The roller-type garbage bag breaking and air-separation structure is a core piece of equipment in modern household waste treatment lines. It cleverly integrates bag breaking, screening, and air separation functions for automated sorting of mixed waste. It mainly consists of a bag breaking mechanism, an air separation system, and a collection mechanism.

[0003] Traditional roller-type garbage bag breaking air separation structures mostly use single-roller or double-roller structures. The garbage bag is torn by blades or toothed structures on the roller. However, when the garbage bag is broken by the blades or toothed structures on the roller, fibrous garbage and garbage bag may accidentally get tangled on the surface, which will affect the normal rotation of the roller and the breaking effect of the blades.

[0007] Preferably, the smoothing unit includes a bevel gear and a slot. The slot is located at the top of the lightweight collection box. The bevel gear is fixedly connected to the end of the rotating shaft away from the reducer. The bevel gear is meshed with a bevel gear on one side. A connecting rod is fixedly connected to a connecting rod on one side. A rotating rod is fixedly connected to a rotating rod at one end through the side wall of the outer shell. A positioning rod is fixedly connected to a positioning rod at one end. A fixing ring is fitted on the outer side of one end of the positioning rod. A push rod is fixedly connected to a push rod at one end. A T-shaped block is fixedly connected to a push rod at one end. The T-shaped block is slidably connected inside the slot.

Detailed Implementation

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

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the present invention provides a technical solution: a roller-type garbage bag breaking and air separation structure, including a shell 1, an inlet 18 is provided at the top of the shell 1, a cover plate 12 is hinged to one side of the inlet 18, a fixing block 9 is fixedly connected to the top of the shell 1, a servo cylinder 10 is rotatably connected to one side of the fixing block 9, a fixing seat 11 is fixedly connected to the output end of the servo cylinder 10, and one side of the fixing seat 11 is rotatably connected to one side of the cover plate 12.

[0018] By activating the servo cylinder 10, the cover plate 12 is pulled upward to rotate, thereby opening the feed port 18. At this time, the staff can put the garbage into the shell 1 through the feed port 18.

[0019] A motor 2 is fixedly connected to one side of the front end of the outer casing 1. A reducer 3 is fixedly connected to the drive end of the motor 2. The reduction ratio of the reducer 3 is 1:100. A rotating shaft 16 is fixedly connected to the output end of the reducer 3 through the outer casing 1. A small roller 17 is fixedly connected to the outside of the rotating shaft 16.

[0020] While the garbage bag is being placed inside the outer casing 1, the motor 2 drives the reducer 3 to rotate the rotating shaft 16. When the rotating shaft 16 rotates, it will drive the small roller 17 to rotate. When the garbage bag comes into contact with the rotating small roller 17, the protrusions on the surface of the small roller 17 will catch the garbage bag, thus fixing the garbage bag to the small roller 17.

[0021] A bag-breaking unit 4 for cutting garbage bags is installed at the front end of the outer casing 1. The bag-breaking unit 4 includes a second motor 406, which is fixedly connected to the middle of the front end of the outer casing 1. A second reducer 407 is fixedly connected to the drive end of the second motor 406. The reduction ratio of the second reducer 407 is 1:60. A first rotating shaft 401 is fixedly connected to the output end of the second reducer 407 through the outer casing 1. A large roller 409 is fixedly connected to the outside of the first rotating shaft 401. A drive gear 408 is sleeved on the outside of the end of the first rotating shaft 401 near the second reducer 407. A support rod 405 is fixedly connected to the front end of the drive gear 408. One end of the support rod 405 is fixedly connected to the inner wall of the outer shell 1. Both sides of the driving gear 408 are meshed with driven gears 402. The rear ends of the two driven gears 402 are fixedly connected to connecting rod 410. One end of the two connecting rods 410 passes through the inner wall of the large roller 409 and is fixedly connected to multiple evenly distributed eccentric wheels 412. Each side of the multiple eccentric wheels 412 is provided with a sliding groove 413. Each sliding groove 413 is slidably connected to a slider 414. One end of each slider 414 is fixedly connected to a cutter 411. One end of each cutter 411 passes through the side wall of the large roller 409.

[0022] The starter motor 406 drives the reducer 407 to rotate the shaft 401. When the shaft 401 rotates, it drives the large drum 409 to rotate. When the large drum 409 rotates, it drives the driven gear 402 to rotate through the drive gear 408. When the driven gear 402 rotates, it drives the eccentric wheel 412 to rotate through the connecting rod 410. When the convex part of the eccentric wheel 412 approaches the side wall of the large drum 409, it pushes the cutter 411 to extend out of the large drum 409 at the part where it intersects with the small drum 17. After puncturing the garbage bag, the speed difference between the large drum 409 and the small drum 17 is used to tear the garbage bag, allowing the garbage inside the garbage bag to spill out.

[0023] The bag-breaking unit 4 also includes two fixing rods 403 and a mounting base 404. The two fixing rods 403 are fixedly connected to the front and rear sides of the inner top wall of the outer casing 1, respectively. The two ends of the mounting base 404 are fixedly connected to the bottom ends of the two fixing rods 403, respectively. Multiple evenly distributed springs 415 are fixedly connected inside the mounting base 404. A push plate 417 is fixedly connected to one end of the multiple springs 415, and a scraper 416 is fixedly connected to one side of the push plate 417.

[0024] When the large roller 409 drives the cutter 411 to rotate away from the small roller 17, the drive gear 408 will push the driven gear 402 to drive the rotating shaft 401 and the eccentric wheel 412 to continue rotating. As the eccentric wheel 412 rotates, its convex part will move away from the side wall of the large roller 409, thereby pulling the cutter 411 back into the large roller 409. At this time, the garbage wrapped on the cutter 411 will be blocked on the outside of the large roller 409. As the large roller 409 rotates, the scraper 416 can scrape and clean the garbage wrapped on the large roller 409. The spring 415 can push the push plate 417 to drive the scraper 416 to extend out of the mounting base 404 and stick tightly to the side wall of the large roller 409 to improve the cleaning effect of the scraper 416.

[0025] A collection box 5 is fixedly connected to one side of the bottom of the outer shell 1. A collection box 6 is fixedly connected to the bottom of the outer shell 1 away from the collection box 5. A guide plate 13 is fixedly connected to one side of the collection box 6. A lightweight discharge port 19 is opened on one side of the outer shell 1. A lightweight collection box 7 is fixedly connected to the side of the outer shell 1 close to the lightweight discharge port 19. An air inlet 14 is opened on the side of the outer shell 1 away from the lightweight discharge port 19. A fan 15 is fixedly connected to the side of the outer shell 1 close to the air inlet 14.

[0026] When the garbage inside the garbage bag spills out, the blower 15 can be activated to deliver outside air into the outer shell 1 through the air inlet 14, thereby performing air separation on the lightweight garbage mixed inside the garbage. The wind force is used to blow the lightweight garbage out of the outer shell 1 through the lightweight discharge port 19 and into the lightweight collection box 7 for collection. At the same time, the remaining heavier garbage will fall into the first collection box 5 due to its own weight. Meanwhile, the garbage that is cleaned off by the scraper 416 and wrapped around the large roller 409 and the cutter 411 will fall onto the guide plate 13 and then be guided by the guide plate 13 into the second collection box 6 for storage.

[0027] Inside the outer casing 1 is a smoothing unit 8 for smoothing lightweight waste. The smoothing unit 8 includes a bevel gear 809 and a slot 812. The slot 812 is located at the top of the lightweight collection box 7. The bevel gear 809 is fixedly connected to the end of the rotating shaft 401 away from the reducer 407. A bevel gear 810 is meshed with one side of the bevel gear 809. A connecting rod 801 is fixedly connected to one side of the bevel gear 810. One end of the connecting rod 801 passes through the side wall of the outer casing 1 and is fixedly connected to a rotating rod 802. A positioning rod 803 is fixedly connected to one end of the rod 802. A fixing ring 804 is sleeved on the outer side of one end of the positioning rod 803. A push rod 808 is fixedly connected to one side of the fixing ring 804. A T-shaped block 807 is fixedly connected to one end of the push rod 808. The T-shaped block 807 is slidably connected inside the slot 812. A cavity 811 is opened inside the T-shaped block 807. An electric telescopic rod 805 is fixedly connected inside the cavity 811. A side plate 806 is fixedly connected to the output end of the electric telescopic rod 805 through the bottom wall of the cavity 811.

[0028] When the rotating shaft 401 rotates, it drives the bevel gear 809 to rotate, and through the cooperation of the bevel gear 810, it drives the connecting rod 801 to rotate. When the connecting rod 801 rotates, it drives the rotating rod 802 to rotate. When the rotating rod 802 rotates, it drives the push rod 808 and the T-block 807 to reciprocate through the cooperation of the positioning rod 803 and the fixing ring 804. During the movement of the T-block 807, it drives the electric telescopic rod 805 to pull the side plate 806 to move together, so that the side plate 806 can smooth out and spread out the locally high accumulation of garbage inside the lightweight collection box 7. By driving the side plate 806 inside the lightweight collection box 7 through the electric telescopic rod 805, the position of the side plate 806 can be adjusted according to the height of the garbage inside the lightweight collection box 7.

[0029] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, a roller-type garbage bag breaking and air separation structure is used. During operation, motor 2 drives reducer 3 to rotate shaft 16. The rotation of shaft 16 causes small roller 17 to rotate. When a garbage bag contacts the rotating small roller 17, the protrusions on the surface of the small roller 17 catch the bag, thus fixing it to the roller 17. Then, servo cylinder 10 pulls the cover plate 12 upwards to open the feed inlet 18. At this time, workers can put garbage into the outer shell 1 through the feed inlet 18. When the garbage bag enters the outer shell 1 and contacts the small roller 17, the protrusions on the surface of the small roller 17 catch the bag. At this point, motor 2 406 is started to drive reducer 2 407 to rotate shaft 1 40. 1. Rotation: When the rotating shaft 401 rotates, it drives the large drum 409 to rotate. The cooperation of the driving gear 408, driven gear 402, connecting rod 410, and eccentric wheel 412 allows the cutter 411 to extend from inside the large drum 409 at the point where it intersects with the small drum 17. This punctures the garbage bag, and the speed difference between the large drum 409 and the small drum 17 tears the bag, causing the garbage inside to spill out. At this time, the blower 15 is activated, delivering external air through the air inlet 14 into the outer casing 1 to perform air separation on the lightweight garbage mixed inside. The airflow then blows the lightweight garbage out of the outer casing 1 through the lightweight discharge port 19 into the lightweight collection box 7 for collection. Meanwhile, the remaining heavier garbage is... Due to its own weight, the material falls into the collection box 5 for collection. When the large roller 409 drives the cutter 411 to rotate away from the small roller 17, the drive gear 408 pushes the driven gear 402 to drive the rotating shaft 401 and the eccentric wheel 412 to continue rotating. As the eccentric wheel 412 rotates, its convex part moves away from the side wall of the large roller 409, thus pulling the cutter 411 back into the large roller 409. At this time, the debris wrapped around the cutter 411 will be blocked on the outside of the large roller 409. As the large roller 409 rotates, the scraper 416 can scrape and clean the debris wrapped around the large roller 409. The cleaned debris will fall onto the guide plate 13 and then be guided into the collection box 6 by the guide plate 13. The lightweight collection bin 7 stores waste in a compacted container. When the rotating shaft 401 rotates, the fixed ring 804 and the push rod 808 can reciprocate through the cooperation of the bevel gear 809, bevel gear 810, connecting rod 801, rotating rod 802, and positioning rod 803. When the push rod 808 moves, it pulls the T-block 807 to reciprocate. During the movement of the T-block 807, it drives the electric telescopic rod 805 to pull the side plate 806 to move together, so that the side plate 806 can smooth out and spread out the locally accumulated waste inside the lightweight collection bin 7. The electric telescopic rod 805 drives the side plate 806 inside the lightweight collection bin 7, thereby adjusting the position of the side plate 806 according to the height of the waste inside the lightweight collection bin 7.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
