Description

Technical Field

[0001] This utility model relates to the field of environmental protection and recycling technology, specifically a plastic bag crushing and recycling device. Background Technology

[0002] Plastic bag crushing and recycling equipment is used in the environmental recycling field to process waste plastic bags. This equipment uses components such as roller cutters to crush the plastic bags, facilitating subsequent recycling and reuse, reducing the environmental pollution caused by plastic bags, and is suitable for plastic bag recycling plants, waste treatment stations, and other similar locations.

[0003] Traditional plastic bag crushing and recycling devices suffer from significant shortcomings in crushing efficiency. Most devices have an unreasonable roller cutter layout, causing plastic bags to accumulate in the middle of the rollers during crushing, hindering thorough crushing and impacting overall efficiency. Furthermore, the scrapers in some devices fail to guide the accumulated plastic bags into the crushing zone, making it difficult to ensure continuous and efficient crushing operations by the rollers, thus failing to meet the high-efficiency crushing requirements of large-scale plastic bag recycling. Therefore, we propose a new plastic bag crushing and recycling device. Utility Model Content

[0004] One of the technical problems this application aims to solve is that existing environmental recycling methods for sorting medicines are manual or semi-automatic, lacking deep integration with hospital information systems. This can easily lead to incorrect medicine collection or misdelivery to departments, resulting in potential medication safety hazards.

[0005] To address the aforementioned technical problems, this application provides a plastic bag crushing and recycling device, comprising a collecting plate, a first power supply device fixedly connected to one outer wall of the collecting plate, a first roller cutter movably connected to both sides of the inner wall of the collecting plate, a first scraper movably connected to both sides of the inner wall of the collecting plate, a connecting column fixedly connected to one outer wall of one side of the first scraper, a connecting mechanism movably connected to one outer wall of one side of the collecting plate, the connecting mechanism including a fixing block, a spring piece fixedly connected to one side of the inner wall of the fixing block, a threaded groove formed on one side of the inner wall of the fixing block, a rotating block movably connected to one side of the inner wall of the fixing block, and a connecting thread formed on one outer wall of one side of the rotating block.

[0006] In some embodiments, a second roller cutter is movably connected to one side of the inner wall of the collecting plate, a fixed plate is fixedly connected to both sides of the inner wall of the collecting plate, a limit block is fixedly connected to the middle of one side of the fixed plate, a second scraper is movably connected to the outer wall of the upper end of the fixed plate, and a connector is movably connected to the outer wall of the upper end of the second scraper.

[0007] In some embodiments, a housing is fixedly connected to the lower end of the collecting plate, a support frame is fixedly connected to one outer wall of the lower end of the housing, a second power supply device is fixedly connected to one inner wall of the lower end of the support frame, a side plate is fixedly connected to one outer wall of the housing, a conveyor belt is movably connected to one inner wall of the side plate, a plurality of push plates are connected to one outer wall of the conveyor belt, and a collecting device is connected to the side of the side plate away from the housing.

[0008] In some embodiments, the second scraper is movably connected to the upper outer wall of the fixed plate via a connector.

[0009] In some embodiments, the connecting post on one side of the outer wall of the first scraper is sequentially connected to one side of the inner wall of the fixing block, the spring piece, and the rotating block.

[0010] In some embodiments, the connecting thread on one side of the outer wall of the rotating block is threadedly connected to the threaded groove on one side of the inner wall of the fixed block.

[0011] In some embodiments, the middle portion of the second hob is movably connected to the limiting block.

[0012] In some embodiments, the first scraper and the second scraper are respectively disposed on the outer walls of the two sides of the first roller cutter, and the second scraper is disposed on the outer walls of the two sides of the second roller cutter.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. In use, the crushing and anti-entanglement structure composed of a first roller cutter, a second roller cutter, a first scraper, a second scraper, a limiting block, and a fixing plate plays a key role in improving crushing efficiency. A first power supply drives the first and second roller cutters to rotate for crushing. The second roller cutter is located in the middle of the two first roller cutters, and its tooth groove is smaller than that of the fixing plate, allowing for further crushing of plastic bags accumulated in the middle of the first roller cutters, preventing accumulation from affecting efficiency. The first scraper is connected to the first roller cutter and can scrape off plastic bags entangled on the first roller cutter. The second scraper is located between the second and first roller cutters, with tooth grooves on both sides matching the corresponding roller cutters, and an inclined surface at the upper end for guiding, guiding the accumulated plastic bags to slide towards the roller cutter while simultaneously scraping the roller cutter, effectively preventing entanglement and ensuring continuous and efficient crushing by the roller cutter, significantly improving the overall crushing efficiency.

[0015] 2. In terms of ease of component maintenance and replacement, the design of the connecting mechanism and the connecting column offers significant advantages in this utility model. The connecting mechanism consists of a fixed block, a spring, a threaded groove, a rotating block, and a connecting thread. The first and second scrapers are connected to the connecting mechanism via the connecting column. When the rotating block is threadedly connected to the fixed block, the spring will move closer to lock the connecting column. Disassembly can be performed by rotating in the opposite direction, replacing the traditional multi-bolt fixing method, avoiding complex disassembly and stripping problems, and facilitating quick installation, disassembly, and replacement of the first and second scrapers, thus improving maintenance efficiency.

[0016] 3. In use, this utility model excels in the convenience of collecting broken materials due to the well-configured components, including the conveyor belt, pusher plate, second power supply, and collection device. The second power supply controls the rotation of the conveyor belt, which in turn moves the pusher plate, pushing the broken plastic bags from the housing into the collection device. This achieves automatic collection of broken materials, eliminating the need for manual cleaning, simplifying the operation process, and improving collection efficiency. Attached Figure Description

[0023] 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.

[0024] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a plastic bag crushing and recycling device, including a collecting plate 1, a first power supply device 2 fixedly connected to one side of the outer wall of the collecting plate 1, a first roller cutter 3 movably connected to both sides of the inner wall of the collecting plate 1, a first scraper 4 movably connected to both sides of the inner wall of the collecting plate 1, a second roller cutter 6 movably connected to one side of the inner wall of the collecting plate 1, a fixing plate 18 fixedly connected to both sides of the inner wall of the collecting plate 1, a limiting block 7 fixedly connected to the middle of one side of the fixing plate 18, the middle of the second roller cutter 6 movably connected to the limiting block 7, a second scraper 5 movably connected to the upper outer wall of the fixing plate 18, the first scraper 4 and the second scraper 5 are respectively disposed on the outer walls of the two sides of the first roller cutter 3, and the second scraper 5 is disposed on the outer walls of the two sides of the second roller cutter 6, the upper outer wall of the second scraper 5... The first scraper 4 is movably connected to a connecting piece 8. The second scraper 5 is movably connected to the upper outer wall of the fixed plate 18 through the connecting piece 8. A connecting post 17 is fixedly connected to one side of the outer wall of the first scraper 4. A connecting mechanism 9 is movably connected to one side of the outer wall of the collecting plate 1. The connecting mechanism 9 includes a fixed block 91. A spring piece 92 is fixedly connected to one side of the inner wall of the fixed block 91. A threaded groove 93 is opened on one side of the inner wall of the fixed block 91. A rotating block 94 is movably connected to one side of the inner wall of the fixed block 91. The connecting post 17 on one side of the outer wall of the first scraper 4 is sequentially connected to the inner wall of the fixed block 91, the spring piece 92, and the rotating block 94. A connecting thread 95 is provided on one side of the outer wall of the rotating block 94. The connecting thread 95 on one side of the outer wall of the rotating block 94 is threadedly connected to the threaded groove 93 opened on one side of the inner wall of the fixed block 91.

[0025] In this embodiment, a collecting plate 1 is designed, with a first power supply device 2 fixedly connected to one side of the collecting plate 1. A first roller cutter 3 is provided on both sides of the inner wall of the collecting plate 1, and one side of the first roller cutter 3 is connected to the first power supply device 2. Therefore, when the first power supply device 2 is activated, it can drive the first roller cutter 3 to rotate, thereby performing a crushing operation. However, existing methods for crushing plastic are prone to entanglement, causing the device to malfunction. To address this, a first scraper 4 is connected to both sides of the inner wall of the collecting plate 1, near the first roller cutter 3. The first scraper 4 is correspondingly connected to the first roller cutter 3, thus enabling the first scraper 4 to scrape off the plastic bag entangled on the first roller cutter 3. However, after prolonged use, the first scraper 4 needs to be cleaned. The replacement of blade 4 is often achieved using a single row of bolts for fixing, which is not only complex to disassemble but also prone to stripping, preventing the replacement of blade 4 and thus affecting the scraping operation. To address this, multiple connecting mechanisms 9 are provided on one side of the outer wall of the collecting plate 1, and multiple connecting posts 17 are fixedly connected to one side of the outer wall of the first scraper blade 4. The connecting posts 17 extend to one side of the outer wall of the collecting plate 1 and are correspondingly connected to the connecting mechanisms 9. Each connecting mechanism 9 includes a fixing block 91, with a spring piece 92 on one side of the inner wall of the fixing block 91. A threaded groove 93 is formed on one side of the inner wall of the fixing block 91 near the spring piece 92. A rotating block 94 is also connected to one side of the inner wall of the fixing block 91, and a connecting thread 95 is provided on one side of the outer wall of the rotating block 94. Therefore, the connecting thread 95 can... The rotating block 94 is threadedly connected to the fixed block 91 via the threaded groove 93. When the rotating block 94 is connected to the inner wall of the fixed block 91, its end is connected to one end of the spring piece 92. The spring piece 92 is elastic, so when the rotating block 94 is threadedly connected to the fixed block 91, it will pull the spring piece 92 inward. The connecting post 17 on one side of the first scraper 4 is connected through the fixed block 91, the spring piece 92, and the inner wall of the rotating block 94. Therefore, the spring piece 92 will lock the connecting post 17, thereby enabling the first scraper 4 to connect to the collecting plate 1. This method facilitates installation and disassembly and improves maintenance efficiency. A fixed plate 18 is fixedly connected to the middle of the inner wall of the collecting plate 1. A limit block 7 is fixedly connected to the middle of the fixed plate 18. Each outer side wall is connected to a second roller cutter 6, and one end of the second roller cutter 6 is connected to the first power supply device 2. Therefore, the second roller cutter 6 also has a crushing operation. However, the tooth groove of the second roller cutter 6 is smaller than that of the fixed plate 18. Since the existing crushing is mainly carried out by the first roller cutter 3, crushed plastic bags will accumulate in the middle of the two first roller cutters 3 during crushing. Long-term accumulation will affect the crushing efficiency of the device. Therefore, the second roller cutter 6 is provided in the middle of the two first roller cutters 3 to further crush the accumulated plastic bags. The upper end of the fixed plate 18 is movably connected to the second scraper 5 through the connector 8. The connector 8 is on the same principle as the connecting mechanism 9, so it can also be disassembled and installed. The second scraper 5 is located between the second roller cutter 6 and the first roller cutter 3.Therefore, the toothed groove on the side near the first roller cutter 3 is the same as that of the first roller cutter 3, and the toothed groove on the side near the second roller cutter 6 is the same as that of the second roller cutter 6. Furthermore, the upper outer wall of the second scraper 5 has an inclined surface, which serves as a guide, allowing the accumulated plastic bags to slide towards the first roller cutter 3 and the second roller cutter 6, thereby better scraping and breaking up the first roller cutter 3 and the second roller cutter 6.

[0026] Example 2: Please refer to Figure 1-3 A housing 10 is fixedly connected to the lower end of the collecting plate 1. A support frame 11 is fixedly connected to the outer wall of one side of the lower end of the housing 10. A second power supply device 12 is fixedly connected to the inner wall of the lower end of the support frame 11. A side plate 15 is fixedly connected to the outer wall of one side of the housing 10. A conveyor belt 13 is movably connected to the inner wall of the side plate 15. Multiple push plates 14 are connected to the outer wall of one side of the conveyor belt 13. A collecting device 16 is connected to the side of the side plate 15 away from the housing 10.

[0027] In this embodiment, a housing 10 is provided at the lower end of the collecting plate 1, and a support frame 11 is provided at the lower end of the housing 10. The support frame 11 provides support, and a second power supply device 12 is provided on the inner wall of the lower end of the support frame 11. A side plate 15 is fixedly connected to one side of the outer wall of the housing 10, and a conveyor belt 13 is movably connected to the inner wall of the side plate 15. Multiple push plates 14 are provided on the outer wall of the conveyor belt 13. The second power supply device 12 can control the conveyor belt 13 to drive it. Therefore, when the second power supply device 12 is activated, the conveyor belt 13 will rotate, thereby causing the push plates 14 to shift. A collection device 16 is provided on the other side of the push plates 14 and the side plate 15. Thus, the conveyor belt 13 and the push plates 14 can push the broken plastic bags in the housing 10 into the collection device 16, thereby completing the collection operation.
