Abstract
Description
Technical Field
[0001] This invention relates to the field of green recycling technology, and more specifically, to a green recycling device for packaging materials. Background Technology
[0002] Currently, paper packaging materials are widely used in logistics, food, e-commerce, and industrial products due to their advantages such as low cost, ease of processing, and recyclability, making them one of the most widely used packaging categories. The recycling of waste corrugated cardboard boxes and other paper packaging requires multiple processes, including crushing, impurity removal, sorting, and pulping, to achieve resource recycling. However, the surface of paper packaging is generally covered with BOPP sealing tape, self-adhesive labels, and other attachments. These tapes are flexible and smooth, with significant differences in physical properties compared to paper materials, posing a pressing challenge in the paper packaging recycling process.
[0003] Currently, conventional sorting equipment is not structurally designed to account for the difference in static friction coefficients between cardboard and tape. The two types of materials are prone to getting tangled and sliding together, which further reduces sorting accuracy. When cardboard mixed with tape particles enters the subsequent pulping and recycling processes, the tape particles will contaminate the pulp, causing problems such as spots, reduced strength, and substandard appearance in recycled paper products, which greatly reduces the quality and market value of recycled paper products.

[0010] Preferably, the first gear meshes with the third gear, the first circular rotating block is rotatably connected with the first circular connecting block, and the annular screening frame and the first circular connecting block together form a screening cavity.
[0011] Preferably, the sealing assembly includes a rectangular sealing plate, a first circular rotating rod connected to the edge of the rectangular sealing plate facing the feed inlet, and a first rectangular connecting block connected to the lower surface of the end of the rectangular sealing plate away from the first circular rotating rod.

[0012] Preferably, the crushing component includes a second drive motor, the output end of the second drive motor is connected to a first circular gear, the end of the first circular gear away from the second drive motor is connected to a first crushing roller, and one end of the first circular gear meshes with a second circular gear.

[0014] Compared with the prior art, the advantages of this invention are:
[0015] 1. In this invention, sorting is achieved by relying on the different static friction coefficients of cardboard particles and adhesive tape particles. The inner wall of the annular screening frame is designed with a rough surface. Cardboard particles with a high coefficient of friction can rotate synchronously with the frame, while adhesive tape and particles with a low coefficient of friction can only slide and remain. This not only separates long strips of adhesive tape, but also has excellent sorting effect on small adhesive particles and label fragments. At the same time, the cardboard screening component and the adhesive tape screening component operate synchronously. The teeth of the adhesive tape screening component can continuously move and comb the mixed materials, breaking up the clumps of paper and adhesive tape. The fine adhesive particles and long strips of adhesive tape mixed in with the cardboard particles are fully separated. The two-stage structure works together to effectively avoid material entanglement, further improve the overall sorting quality, and ensure the purity of the output.
[0016] 2. In this invention, by using a pair of counter-rotating crushing rollers and a matching cleaning rod, the cleaning grooves and crushing teeth are precisely matched. During the crushing operation, the tape, glue, and other debris wrapped around the rollers can be scraped off in real time. This avoids problems such as equipment jamming, motor overload, and accelerated wear of parts caused by tape wrapping, which greatly reduces the probability of equipment failure and downtime and maintenance costs, and ensures continuous and efficient operation of the crushing process.
[0017] 3. In this invention, by setting a sealing component at the feed inlet, the sealing plate automatically opens under pressure when the material is fed in, and automatically closes with the help of a reset spring after the feeding is completed. This effectively prevents paper dust and glue scraps generated during the crushing and screening process from drifting outward, improves the workshop working environment, and eliminates dust pollution and dust safety hazards.

[0027] Example: Please refer to Figure 1 and Figure 8 A green recycling and processing device for packaging materials includes a main body 1, an inlet 2 connected to the upper end of one side of the main body 1, sealing components 3 connected to both ends of the inner cavity of the inlet 2, a crushing component 4 installed directly below the sealing component 3, a screening component 5 installed directly below the crushing component 4, a first storage cavity 6 connected to the end of the screening component 5 away from the crushing component 4, and a second storage cavity 7 connected to the end of the first storage cavity 6 away from the screening component 5.
[0028] Please see Figure 2 and Figure 3The screening component 5 includes a cardboard screening component 501, with a first circular connecting block 502 connected to both ends of the cardboard screening component 501. A tape screening component 503 is connected to the outer surface of the first circular connecting block 502 connected to the end away from the crushing component 4. One end of the tape screening component 503 is connected to a first conveying pipe 505. A second conveying pipe 504 is connected to the upper end of the first conveying pipe 505. The feed pipe 507 is located directly below the crushing component 4. The first conveying pipe 505 is located directly above the first receiving cavity 6, and the second conveying pipe 504 is located directly above the second receiving cavity 7.
[0029] Please see Figure 2 and Figure 3 A third feed pipe 506 is connected to the outer surface of the first circular connecting block 502 near one end of the crushing component 4. The end of the third feed pipe 506 facing the crushing component 4 is connected to the feed pipe 507. A first guide plate 508 is installed in the inner cavity of the cardboard screening component 501. A second guide plate 509 is connected to one end of the tape screening component 503. The first feed pipe 505 corresponds to the second guide plate 509, and the second feed pipe 504 corresponds to the first guide plate 508. The two guide plates are connected to the inner surface of the first circular connecting block 502.
[0030] Please see Figure 4 The cardboard screening assembly 501 includes a first drive motor 510, the output end of the first drive motor 510 is connected to a first rotating rod 511, the end of the first rotating rod 511 away from the first drive motor 510 is connected to a first gear 512, and the outer surface of the end of the first rotating rod 511 facing the first drive motor 510 is connected to a second gear 513, the outer side of the second gear 513 is meshed with an external gear ring 514, the inner cavity of the external gear ring 514 is connected to an annular screening frame 515, the annular screening frame 515 is rotatably connected to a first circular connecting block 502, and the first circular connecting block 502 is fixed in the inner cavity of the equipment body 1.
[0031] Specifically, the sorting is achieved by relying on the different static friction coefficients of cardboard particles and tape particles: the inner wall of the annular screening frame 515 is designed with a rough surface, allowing cardboard particles with a high coefficient of friction to rotate synchronously with the frame, while tape and adhesive particles with a low coefficient of friction can only slide and remain. This not only separates long strips of tape, but also has excellent sorting effect on small adhesive particles and label fragments. At the same time, the cardboard screening component 501 and the tape screening component 503 operate synchronously. The teeth 519 of the tape screening component 503 continuously move and comb the mixed materials, breaking up the clumps of paper and tape, and fully peeling off the small adhesive particles and long strips of tape mixed in with the cardboard particles. The two-stage structure works together to effectively avoid material entanglement, further improve the overall sorting quality, and ensure the purity of the output.
[0032] Please see Figure 5 The tape screening assembly 503 includes a third gear 516. A first circular rotating block 517 is connected to one end of the third gear 516 facing the feed inlet 2. A plurality of third circular rotating rods 518 are connected to one end of the first circular rotating block 517 facing the middle part of the annular screening frame 515. A plurality of teeth 519 are connected to the outer surface of each third circular rotating rod 518.
[0033] Please see Figure 3 The first gear 512 meshes with the third gear 516, the first circular rotating block 517 is rotatably connected with the first circular connecting block 502, and the annular screening frame 515 and the first circular connecting block 502 together form the screening cavity.
[0034] Please see Figure 6 The sealing assembly 3 includes a rectangular sealing plate 301. A first circular rotating rod 302 is connected to the edge of the rectangular sealing plate 301 facing the feed inlet 2. A first rectangular connecting block 303 is connected to the lower surface of the end of the rectangular sealing plate 301 away from the first circular rotating rod 302. An inclined return spring 304 is connected to the end surface of the first rectangular connecting block 303 facing the first circular rotating rod 302. A second rectangular connecting block 305 is connected to the end of the inclined return spring 304 away from the first rectangular connecting block 303. The second rectangular connecting block 305 is installed on the inner cavity surface of the feed inlet 2.
[0035] Specifically, by setting a sealing component 3 at the feed inlet 2, the sealing plate automatically opens under pressure when the material is fed in, and automatically closes with the help of a reset spring after the feeding is completed. This effectively prevents paper dust and glue scraps generated during the crushing and screening process from drifting outward, improving the workshop working environment and eliminating dust pollution and dust safety hazards.
[0036] Please see Figure 7 The crushing component 4 includes a second drive motor 401, the output end of the second drive motor 401 is connected to a first circular gear 402, the end of the first circular gear 402 away from the second drive motor 401 is connected to a first crushing roller 403, and one end of the first circular gear 402 is meshed with a second circular gear 404.
[0037] Please see Figure 7 The second circular gear 404 is connected to a second crushing roller 405 at one end away from the second drive motor 401. The second crushing roller 405 and the first crushing roller 403 are both connected to a cleaning rod 406 at one end away from the edge of the main body 1. Each cleaning rod 406 has several cleaning grooves 407 at one end facing the crushing roller, and the cleaning grooves 407 are matched with the crushing tooth tips connected to the surface of the crushing roller. The feed inlet 2 is located in the central crushing area of the two crushing rollers.
[0038] Specifically, by using paired counter-rotating crushing rollers and equipped with cleaning rods 406 and cleaning grooves 407 that precisely match the crushing teeth, the tape, filaments and other debris wrapped around the rollers can be scraped off in real time during the crushing operation. This avoids problems such as equipment jamming, motor overload and accelerated wear of parts caused by tape wrapping, significantly reducing the probability of equipment failure and downtime and maintenance costs, and ensuring continuous and efficient operation of the crushing process.
[0039] Working principle: First, the cardboard to be shredded is fed into the feed inlet 2. At this time, the cardboard will exert pressure on the rectangular sealing plate 301, causing the inclined return spring 304 to retract, which in turn causes the rectangular sealing plate 301 to rotate along the first circular rotating rod 302. This opens the feed inlet 2, allowing the cardboard to fall into the central shredding area of the shredding assembly 4. At this time, the two drive motors are started through the control box. The start of the second drive motor 401 will drive the first circular gear 402 and the first shredding roller 403 to rotate toward the shredding interval of the two shredding rollers. At the same time, as the first circular gear 402 rotates, it will drive the second circular gear 404 and the second shredding roller 405 to rotate toward the shredding interval of the two shredding rollers, thereby shredding the cardboard. During the rotation of the two shredding rollers, the cleaning rod 406 will clean the surface of the shredding rollers in real time to prevent the tape from getting tangled on the surface of the rollers.
[0040] The shredded cardboard falls into the feed pipe 507 and is then conveyed through the feed pipe 507 to the third conveying pipe 506. The shredded cardboard and tape are then conveyed through the third conveying pipe 506 to the screening chamber. At this time, the start of the first drive motor 510 drives the first rotating rod 511, the first gear 512, and the second gear 513 to rotate synchronously. As the second gear 513 rotates, it drives the outer gear ring 514 to rotate, thereby causing the annular screening frame 515 to rotate slowly. The inner surface of the annular screening frame 515 is rough. This will generate a frictional force on the cardboard particles. Since the friction coefficient of the tape is lower than that of the cardboard particles, the tape particles will always be at the bottom of the annular screening frame 515. The cardboard particles will rotate with the rotation of the annular screening frame 515 until the cardboard particles rotate to the top of the first guide plate 508. The cardboard particles will fall into the inner surface of the first guide plate 508 due to gravity. Since the screening assembly 5 is inclined, the cardboard particles will be transported along the first guide plate 508 through the second conveying pipe 504 to the second receiving cavity 7.
[0041] Furthermore, the rotation of the first gear 512 will drive the third gear 516 to rotate, thereby driving the first circular rotating block 517 to rotate, which in turn drives several third circular rotating rods 518 to rotate. As the third circular rotating rods 518 rotate, they will drive several teeth 519 to perform a screening operation on the tape located in the annular screening frame 515, and then transport the screened tape to the second guide plate 509, and then to the first receiving cavity 6 through the first conveying pipe 505. In this way, the tape screening assembly 503 and the paperboard screening assembly 501 screen the paperboard and tape separately until all the crushed paperboard is screened. Then the screened paperboard particles are transported to the next operation step for recycling, thus ending all operations.
