Description

Technical Field

[0001] This invention belongs to the field of plastic processing technology, specifically a scrap recycling device for plastic pallet production. Background Technology

[0002] Plastic pallets are logistics unit tools used in conjunction with forklifts, racks, and other logistics equipment. They are mainly used for the containerization, stacking, handling, and transportation of goods and are an indispensable piece of logistics equipment in modern logistics warehousing. Due to their significant advantages such as light weight, impact resistance, easy cleaning, corrosion resistance, and recyclability, plastic pallets are widely used in logistics, warehousing, food, and pharmaceutical industries. After processing, plastic pallets often have burrs on their edges, requiring trimming. These burrs can cut operators' hands or tear packaging, and uneven edges can cause pallets to jam on conveyor lines and racks, affecting automated operations. Trimmed scraps can be recycled, saving resources and protecting the environment.

[0003] In existing technology, after trimming the edges of plastic pallets, the trimmed plastic scraps are usually collected together and then transferred to a crusher for crushing. Generally, workers manually feed the scraps into the crusher in batches for crushing.

[0004] The main pollutants generated during plastic crushing are dust and high-decibel noise. Without proper protection, these pollutants can be harmful to health. Furthermore, manual feeding makes it difficult to accurately control the amount of material fed in, and uneven feeding speed can lead to overloading or idling, affecting crushing efficiency and equipment lifespan.

[0017] The beneficial effects of this invention are as follows: 1. The edge material recycling device for plastic pallet production of the present invention precisely controls the amount of edge material entering the first rectangular frame by driving the sliding plate to slide up and down, thereby reducing the overload or empty load caused by uneven feeding speed. Then, the extrusion plate is driven to slide down to perform preliminary extrusion on the edge material at the upper end of the first rectangular plate. Then, the first rectangular plate is driven to rotate, so that the first rectangular plate tilts towards the crushing box, so that the edge material after being extruded at the upper end of the first rectangular plate enters the crushing box for crushing. After preliminary extrusion, crushing is performed, which can effectively avoid material jamming and overload, protect the equipment and improve the uniformity of output.

[0018] 2. The edge material recycling device for plastic pallet production of the present invention, by driving a second rectangular bar to move an extrusion roller on the upper part of a filter plate, and the second rectangular bar driving a spray nozzle to move simultaneously via a third rectangular bar, allows the extrusion roller to extrude the edge material on the upper part of the filter plate while the spray nozzle sprays water to wash the edge material. The washing water falls through the filter plate to the lower end of the cleaning tank and is then discharged through the drain outlet. Simultaneously, the movement of the extrusion roller causes a baffle to move to one side, which in turn causes a scraper to follow the extrusion roller to move to one side. The baffle and scraper push the edge material on the upper part of the filter plate to one side. When the extrusion roller slides into the cleaning tank near the discharge port, the second rectangular bar drives a third rectangular plate to slide to one side. The third rectangular plate slides to the side of a cylindrical block, which enters a beveled groove. The beveled groove slides outside the cylindrical block and is inclined. As the third rectangular plate slides outside the cylindrical block, it moves upward, and the third rectangular plate drives the extrusion roller to move upward via the second rectangular bar. At this time, the extrusion roller drives the baffle to move upward, and the spring inside the baffle pushes the scraper downward, so that the scraper always sticks tightly to the upper part of the filter plate. The scraper scrapes the scrap material on the upper part of the filter plate to the discharge port side, and the scrap material is discharged from the discharge port. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figure 1 - Figure 7 As shown in the embodiment of the present invention, a scrap recycling device for plastic pallet production includes a first rectangular frame 1. A preliminary extrusion assembly is provided inside the first rectangular frame 1. The preliminary extrusion assembly includes a first rectangular plate 11 rotatably disposed at the lower end of the first rectangular frame 1. An extrusion plate 12 is slidably disposed at the upper end of the first rectangular plate 11. First feed inlets 13 are fixedly connected to both sides of the first rectangular frame 1. The first feed inlets 13 communicate with the interior of the first rectangular frame 1. A sliding plate 131 is slidably disposed between the first feed inlet 13 and the first rectangular frame 1. A crushing box 2 is provided on one side of the first rectangular frame 1. The crushing box 2 is connected to the first rectangular frame 1 through a second feed inlet 21. Two crushing rollers 22 are rotatably disposed inside the crushing box 2.

[0023] Specifically, in existing technologies, after trimming plastic pallets, the trimmed plastic scraps are generally collected together and then transferred to a crusher for crushing. Workers typically manually feed the scraps into the crusher in batches. This crushing process mainly generates dust and high-decibel noise, which is harmful to health if proper precautions are not taken. Furthermore, manual feeding makes it difficult to accurately control the amount of material fed in, and uneven feeding speeds can lead to overloading or idling, thus affecting crushing efficiency and equipment lifespan. In this recycling device, the scraps are fed into the first feed inlet 13, and the amount of scrap entering the first rectangular frame 1 is controlled by sliding the slide plate 131 up and down. After entering the first rectangular frame 1 through the first feed inlet 13, the scraps fall onto the upper end of the first rectangular plate 11, and then the extrusion plate 12 slides downwards, crushing the scraps on the upper end of the first rectangular plate 11. The material undergoes initial compression to crush the scrap. After compression, the first rectangular plate 11 is rotated, tilting towards the crushing box 2, allowing the crushed scrap to enter the crushing box 2. The crushing roller 22 is then rotated to crush the scrap. The sliding plate 131 is driven to slide up and down, precisely controlling the amount of scrap entering the first rectangular plate 1 and reducing the risk of overload or idling due to uneven feeding speed. The extrusion plate 12 is then driven to slide down to initially compress the scrap at the top of the first rectangular plate 11. The first rectangular plate 11 is then rotated, tilting towards the crushing box 2, allowing the crushed scrap to enter the crushing box 2 for further crushing. This initial compression followed by crushing effectively prevents jamming and overload, protects the equipment, and improves the uniformity of output.

[0024] like Figure 3 As shown, the upper end of the first rectangular plate 11 is provided with several conical grooves, and the lower end of the extrusion plate 12 is provided with several conical protrusions corresponding to the positions of the several conical grooves on the upper end of the first rectangular plate 11.

[0025] like Figure 3 - Figure 4 As shown, cylindrical rods 121 are fixed to both sides of the upper end of the extrusion plate 12, and T-shaped strips 122 are fixed to the upper ends of the cylindrical rods 121. A second hydraulic rod 123 is fixed to one side of the lower end of the T-shaped strip 122. The second hydraulic rod 123 is fixed to one side of the first rectangular frame 1 through a second support block 134.

[0026] Specifically, by driving the second hydraulic rod 123 to retract, the second hydraulic rod 123 drives the cylindrical rod 121 to move downward through the T-shaped strip 122. The cylindrical rod 121 drives the extrusion plate 12 to move downward. The extrusion plate 12 extrudes the scrap material at the upper end of the first rectangular plate 11. The conical groove at the upper end of the first rectangular plate 11 and the conical protrusion at the lower end of the extrusion plate 12 can improve the crushing effect of the scrap material during extrusion.

[0027] like Figure 3 - Figure 4 As shown, a second rectangular frame 15 is provided at the lower end of the first rectangular frame 1, a first rectangular block 111 is fixedly connected to the lower end of the first rectangular plate 11, the first rectangular block 111 is slidably disposed at the lower end of the first rectangular frame 1, a first rectangular strip 112 is rotatably connected to the lower end of the first rectangular block 111, a second rectangular plate 113 is slidably disposed at the lower end of the first rectangular strip 112, the second rectangular plate 113 is slidably disposed within the second rectangular frame 15, a first hydraulic rod 114 is fixedly connected to the lower end of the second rectangular plate 113, and the first hydraulic rod 114 is fixedly connected to the inside of the second rectangular frame 15 through a first support block 115.

[0028] Specifically, after the scrap material is extruded, the first hydraulic rod 114 is extended by driving the first hydraulic rod 114 to move the first rectangular bar 112 upward through the second rectangular plate 113. The first rectangular bar 112 drives the first rectangular plate 11 to rotate within the first rectangular frame 1 through the first rectangular block 111, so that the scrap material at the upper end of the first rectangular plate 11 slides into the crushing box 2 for crushing again.

[0029] like Figure 2 - Figure 3 As shown, a storage frame 14 is fixedly connected to the upper end of the two first feed ports 13. The storage frame 14 is connected to the interior of the first feed port 13, and the lower two sides of the storage frame 14 are inclined.

[0030] like Figure 4 As shown, the upper ends of the two slide plates 131 are jointly fixed with a U-shaped strip 132, and a third hydraulic rod 133 is fixed to one side of the lower end of the U-shaped strip 132. The third hydraulic rod 133 is fixed to one side of the first rectangular frame 1 through a second support block 134.

[0031] Specifically, by placing a large amount of scrap material inside the storage frame 14, with the lower two sides of the storage frame 14 tilted toward the first feed inlet 13, the scrap material inside the storage frame 14 can automatically slide into the first feed inlet 13. By driving the third hydraulic rod 133 to extend and retract, the third hydraulic rod 133 drives the slide plate 131 to slide up and down through the U-shaped strip 132, thereby accurately controlling the amount of scrap material entering the first rectangular frame 1.

[0032] like Figure 6As shown, a third feed inlet 23 is fixedly connected to the lower end of the crushing box 2. The crushing box 2 and the third feed inlet 23 are internally connected. A cleaning box 3 is fixedly connected to the end of the third feed inlet 23 away from the crushing box 2. The third feed inlet 23 and the cleaning box 3 are internally connected. A filter plate 35 is provided at the lower end of the interior of the cleaning box 3. A squeezing roller 32 is rolled on the upper end of the filter plate 35.

[0033] like Figure 6 As shown, the surface of the extrusion roller 32 is provided with several conical blocks, and the two sides of the extrusion roller 32 are rotatably provided with second rectangular bars 321. The upper end of the cleaning box 3 is provided with rectangular holes 31 corresponding to the positions of the second rectangular bars 321. The second rectangular bars 321 are slidably disposed in the rectangular holes 31. On the opposite side of the second rectangular bars 321, L-shaped blocks 34 are slidably disposed. A fourth hydraulic rod 341 is fixedly connected to one side of the L-shaped blocks 34. The fourth hydraulic rod 341 is fixedly connected to one side of the third feed port 23.

[0034] Specifically, the scrap material crushed by the crushing box 2 enters the cleaning box 3 through the third feed port 23, causing the scrap material to fall on the upper end of the filter plate 35. Then, by driving the fourth hydraulic rod 341 to extend, the fourth hydraulic rod 341 drives the second rectangular bar 321 to slide to one side in the rectangular hole 31 through the L-shaped block 34. The second rectangular bar 321 drives the extrusion roller 32 to move on the upper end of the filter plate 35, and the extrusion roller 32 extrudes the scrap material on the upper end of the filter plate 35 again.

[0035] Example 2: Figure 6 - Figure 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a third rectangular strip 39 is fixedly connected to the upper end between the two second rectangular strips 321, a plurality of nozzles 391 are provided at the lower end of the third rectangular strip 39, a baffle 33 is fixedly connected between the two second rectangular strips 321, a rectangular groove 331 is provided at the lower end of the baffle 33, a scraper 333 is slidably arranged inside the rectangular groove 331, and the scraper 333 is fixedly connected to the inside of the rectangular groove 331 by a spring 332.

[0036] like Figure 6 - Figure 7 As shown, a third rectangular plate 322 is fixedly connected to the upper end of the second rectangular strip 321. A beveled groove 3221 is opened on one side of the third rectangular plate 322. Support rods 36 are fixedly connected to both sides of the upper end of the cleaning tank 3. A cylindrical block 361 is fixedly connected to one side of the support rod 36 at the position corresponding to the beveled groove 3221. A drain outlet 38 is provided at the lower end of one side of the cleaning tank 3. A discharge outlet 37 is provided at the upper end of one side of the cleaning tank 3. The drain outlet 38 is located at the lower end of the filter plate 35, and the discharge outlet 37 is located at the upper end of the filter plate 35.

[0037] Specifically, when the second rectangular bar 321 drives the extrusion roller 32 to move on the upper end of the filter plate 35, the second rectangular bar 321 drives the nozzle 391 to move simultaneously via the third rectangular bar 39. While the extrusion roller 32 extrudes the scrap material on the upper end of the filter plate 35, the nozzle 391 sprays water to wash the scrap material. The washing water falls through the filter plate 35 to the lower end of the cleaning tank 3 and is then discharged through the drain outlet 38. Simultaneously, the movement of the extrusion roller 32 drives the baffle 33 to move to one side. The baffle 33 drives the scraper 333 to follow the extrusion roller 32 to move to one side, thus cleaning the filter material. The scrap material at the upper end of plate 35 is pushed to one side. When the extrusion roller 32 slides into the cleaning tank 3 near the discharge port 37, the second rectangular bar 321 drives the third rectangular plate 322 to slide to one side. The third rectangular plate 322 slides to the side of the cylindrical block 361. The cylindrical block 361 enters the inclined groove 3221. The inclined groove 3221 slides on the outside of the cylindrical block 361. The inclined groove 3221 is inclined. When the third rectangular plate 322 slides on the outside of the cylindrical block 361, the third rectangular plate 322 moves upward. The third rectangular plate 322 drives the extrusion roller 32 to move upward through the second rectangular bar 321. At this time, the extrusion roller 32 drives the baffle 33 to move upward. The spring 332 inside the baffle 33 pushes the scraper 333 downward, so that the scraper 333 is always in close contact with the upper end of the filter plate 35. The scraper 333 scrapes the scrap material at the upper end of the filter plate 35 to the side of the discharge port 37. The scrap material is discharged from the discharge port 37.

[0038] Working principle: A large amount of scrap material is placed inside the storage frame 14. The lower two sides of the storage frame 14 are inclined towards the first feed inlet 13. The scrap material in the storage frame 14 can automatically slide into the first feed inlet 13. By driving the third hydraulic rod 133 to extend and retract, the third hydraulic rod 133 drives the slide plate 131 to slide up and down through the U-shaped strip 132, thereby accurately controlling the amount of scrap material entering the first rectangular frame 1. After the scrap material enters the first rectangular frame 1 through the first feed inlet 13, the scrap material falls on the upper end of the first rectangular plate 11. By driving the second hydraulic rod 123 to retract, the second hydraulic rod... The pressure bar 123 drives the cylindrical bar 121 to move downward through the T-shaped bar 122. The cylindrical bar 121 drives the extrusion plate 12 to move downward. The extrusion plate 12 extrudes the scrap material at the upper end of the first rectangular plate 11. After the scrap material is extruded, the first hydraulic bar 114 is extended by driving the first hydraulic bar 114 to move upward through the second rectangular plate 113. The first rectangular bar 112 drives the first rectangular plate 11 to rotate within the first rectangular frame 1 through the first rectangular block 111, so that the scrap material at the upper end of the first rectangular plate 11 slides into the crushing box 2 for crushing again. The scrap material crushed in the crushing chamber 2 enters the cleaning chamber 3 through the third feed inlet 23, causing it to fall onto the upper end of the filter plate 35. Then, by driving the fourth hydraulic rod 341 to extend, the fourth hydraulic rod 341 drives the second rectangular bar 321 to slide to one side within the rectangular hole 31 via the L-shaped block 34. The second rectangular bar 321 drives the extrusion roller 32 to move on the upper end of the filter plate 35, further extruding the scrap material. While the second rectangular bar 321 drives the extrusion roller 32 to move on the upper end of the filter plate 35, the second rectangular bar 321 also drives the nozzle 391 to move simultaneously via the third rectangular bar 39. While the extrusion roller 32 extrudes the scrap material on the upper end of the filter plate 35, the nozzle 391 sprays water to wash the scrap material. The washing water falls into the cleaning chamber 3 after passing through the filter plate 35. The lower end is then discharged through the drain outlet 38. As the extrusion roller 32 moves, it simultaneously moves the baffle 33 to one side. The baffle 33, in turn, moves the scraper 333 to one side, pushing the scrap material from the upper end of the filter plate 35 to one side. When the extrusion roller 32 slides into the cleaning tank 3 near the discharge outlet 37, the second rectangular bar 321 moves the third rectangular plate 322 to one side. The third rectangular plate 322 slides to one side of the cylindrical block 361, and the cylindrical block 361 enters the inclined groove 3221. The inclined groove 3221 slides outside the cylindrical block 361 and is inclined. As the third rectangular plate 322 slides outside the cylindrical block 361, it moves upward. The third rectangular plate 322, through the second rectangular bar 321, moves the extrusion roller 32 upward. At this time, the extrusion roller 32 drives the baffle 33 to move upward, and the spring 332 inside the baffle 33 pushes the scraper 333 downward, so that the scraper 333 is always in close contact with the upper end of the filter plate 35. The scraper 333 scrapes the scrap material at the upper end of the filter plate 35 to the side of the discharge port 37, and the scrap material is discharged from the discharge port 37.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
