Description

Technical Field

[0001] This utility model relates to the field of cardboard recycling technology, and in particular to environmentally friendly cardboard label waste recycling and reuse processing equipment. Background Technology

[0002] Cardboard labels are identification carriers made primarily from paper pulp through coating, printing, and die-cutting processes. They are widely used in commodity packaging, logistics and transportation, and library management. Their base material is kraft paper, coated paper, or specialty paper, which has good flexibility and printability. They can be printed with text, patterns, and barcodes through offset printing, flexographic printing, and digital printing to meet the needs of different usage scenarios.

[0003] In the commodity circulation process, cardboard labels are used to mark product names, ingredients, specifications and production dates to help consumers identify and select products. In the logistics and warehousing field, they serve as cargo identifiers to facilitate automated sorting and inventory management. However, with the expansion of commodity production and circulation, the amount of waste generated after the use of cardboard labels has increased dramatically. If these wastes are discarded directly, they will not only occupy a large amount of landfill space, but their degradation process will also cause environmental pollution. Therefore, recycling and reusing cardboard label waste has become an important issue that urgently needs to be addressed in the field of resource recycling.

[0004] However, existing equipment suffers from significant water waste during operation. The crushing process relies on a large amount of water for flushing and dilution, and the water is only used as a single auxiliary crushing medium. During the crushing process, water mixes with waste to form pulp, which is then discharged directly after entering the sedimentation stage. In addition, some equipment blindly increases the water supply to ensure crushing efficiency, resulting in actual water consumption far exceeding the process requirements. This operating mode not only significantly increases water consumption during processing but also raises wastewater treatment costs. Furthermore, the waste of a large amount of water contradicts the current advocacy of green circular economy and restricts the sustainable development of the cardboard label waste recycling industry.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of an environmentally friendly cardboard label waste recycling and processing equipment, including an equipment frame 1, a mixing tank 3 fixedly connected to the top right side of the equipment frame 1, a multi-stage crushing mechanism 2 inside the mixing tank 3, a water supply pipe 4 connected to the top right side of the mixing tank 3, a feeding trough 5 connected to the top front side of the mixing tank 3, a water pump 6 fixedly connected to the bottom right side of the equipment frame 1, a sedimentation tank 7 opened on the top left side of the equipment frame 1, the input end of the water pump 6 connected to the bottom right side of the mixing tank 3, the output end of the water pump 6 connected to the inside right side of the sedimentation tank 7, a sedimentation filter screen 8 fixedly connected to the inside rear side of the sedimentation tank 7, a carrier plate 9 fixedly connected to the top rear side of the equipment frame 1, a water pump 10 fixedly connected to the top right side of the carrier plate 9, the input end of the water pump 10 connected to the inside rear side of the sedimentation tank 7, and the output end of the water pump 10 connected to the rear top side of the mixing tank 3;

[0033] Specifically, waste cardboard labels are poured from the feeding trough 5 into the mixing tank 3. The multi-stage crushing mechanism 2 inside the mixing tank 3 is activated to gradually crush the waste. At the same time, water is injected into the mixing tank 3 through the water supply pipe 4, mixing with the crushed waste to form pulp. Through the coordinated work of the multi-stage crushing mechanism 2 and the water supply pipe 4, the waste is crushed and made into pulp, thus solving the problem that the waste cannot be directly reused. The water pump 6 on the bottom right side of the equipment frame 1 is activated. Its input end is connected to the bottom right side of the mixing tank 3, drawing out the pulp from the mixing tank 3 and conveying it to the sedimentation tank 7 on the top left side of the equipment frame 1 through the output end. After the pulp enters the sedimentation tank 7, the sedimentation filter 8 intercepts the fibrous material in the pulp, while the water flows through the sedimentation filter 8 to the other side. By combining water pump 6 and sedimentation filter 8, the pulp is transported to sedimentation tank 7 and the fibers are settled, thus solving the problem of fiber concentration. Water pump 10 on the rear support plate 9 at the top of the equipment frame 1 is started. Its input end is connected to the rear of the sedimentation tank 7, and the water settled behind the filter is extracted and transported back to the top of the rear of the mixing tank 3 through the output end. The water returned to the mixing tank 3 is mixed with the newly added waste and water for the next round of processing, realizing the recycling and reuse of settled fibers, greatly reducing the waste of water resources. From waste crushing and mixing to pulp conveying and sedimentation, and then to fiber recycling, the efficient recycling and reuse of environmentally friendly cardboard label waste is realized, reducing production costs while reducing resource waste and environmental pollution.

[0034] Reference Figure 1 and Figure 4 The multi-stage crushing mechanism 2 includes a drive motor 201, which is fixedly connected to the top of the mixing tank 3. The output end of the drive motor 201 is fixedly connected to a stirring shaft 202, which is rotatably connected to the inside of the mixing tank 3. Two crushing blades 203 are fixedly connected to the upper part of the outer wall of the stirring shaft 202, and multiple cutting blades 204 are fixedly connected to the lower part of the outer wall of the stirring shaft 202. A coarse filter screen 205 is fixedly connected to the upper part of the inner side of the mixing tank 3, and a fine filter screen 206 is fixedly connected to the lower part of the inner side of the mixing tank 3. The two crushing blades 203 are located on top of the coarse filter screen 205, and the multiple cutting blades 204 are located between the coarse filter screen 205 and the fine filter screen 206.

[0035] Specifically, the drive motor 201 is fixed to the top of the mixing tank 3. After starting, its output end drives the mixing shaft 202 to rotate inside the mixing tank 3. The two crushing blades 203 on the upper part of the outer wall of the mixing shaft 202 rotate at high speed with the mixing shaft 202, performing initial crushing of the cardboard label waste entering the mixing tank 3 from the feeding trough 5. Larger pieces of waste are broken down into smaller pieces by the impact and cutting of the crushing blades 203. Through the cooperation of the drive motor 201 and the crushing blades 203, the initial crushing effect of the waste is achieved, thus solving the problem of large pieces of waste being difficult to handle. The waste fragments after the initial crushing fall into the area between the coarse filter screen 205 and the fine filter screen 206. At this time, multiple cutting blades 204 on the lower part of the outer wall of the mixing shaft 202 continue to perform secondary cutting of the waste. The cutting blades 204 further cut the fragments, making them smaller in size. At the same time, the coarse filter screen 205 and the fine filter screen 206 play a screening role. 5. Larger waste fragments are intercepted and allowed to continue to be processed by the cutting blade 204. Fragments that meet certain size requirements pass through the coarse filter 205. Through the cooperation of the cutting blade 204 and the coarse filter 205, the waste is further refined and initially screened, thus solving the problem of uneven waste fragment size affecting subsequent processing. Waste fragments passing through the coarse filter 205 continue to fall, and the fine filter 206 screens them again. Fragments that do not meet the required size are intercepted by the fine filter 206 and continue to be finely crushed by the cutting blade 204. Fragments that meet the required size pass through the fine filter 206 and are mixed with water injected by the water supply pipe 4 to form pulp. After multi-stage crushing and screening, it is ensured that the waste particles in the final pulp are of uniform size. Through the cooperation of the fine filter 206 and the cutting blade 204, the waste is finely crushed and qualified pulp is separated, thus solving the problem of poor pulp quality affecting waste recycling.

[0036] Reference Figure 1 , Figure 3 and Figure 5A control console 11 is fixedly connected to the front left end of the equipment frame 1. The control console 11 is electrically connected to water pump 6, water pump 10, and drive motor 201. A discharge pipe 12 is connected to the rear bottom of the equipment frame 1. The top end of the discharge pipe 12 is connected to the bottom inside of the sedimentation tank 7. A solenoid valve 13 is fixedly installed in the middle of the discharge pipe 12 and is electrically connected to the control console 11. A work indicator light 14 is fixedly connected to the top left side of the equipment frame 1. The work indicator light 14 is electrically connected to the drive motor 201. The equipment rack 1 has four fixed corners at its bottom, each with a shock-absorbing pad 15. The bottoms of the shock-absorbing pads 15 are designed to be non-slip. The front of the carrier plate 9 is rotatably connected to a dust cover 16. The top of the dust cover 16 is fixedly connected to a handle 17. The front inner side of the sedimentation tank 7 is fixedly connected to two magnetic blocks 18. The tops of the magnetic blocks 18 are magnetically connected to the bottoms of the dust cover 16. The rear top of the feeding trough 5 is rotatably connected to a cover plate 19. The bottom of the cover plate 19 is attached to the top of the feeding trough 5.

[0037] Specifically, the control console 11, fixedly connected to the front left end of the equipment frame 1, is electrically connected to water pump 6, water pump 10, and drive motor 201, achieving centralized control of equipment operation and solving the problem of inconvenient decentralized operation. The top of the discharge pipe 12 at the bottom rear end of the equipment frame 1 is connected to the bottom of the sedimentation tank 7, and the solenoid valve 13 fixedly installed in the middle is electrically connected to the control console 11. After the pulp in the sedimentation tank 7 has undergone multiple sedimentation processes, the control console 11 controls the solenoid valve 13 to open, and the dirtier water can be discharged through the discharge pipe 12. Through the cooperation of the control console 11 and the solenoid valve 13, precise control of the pulp output in the sedimentation tank 7 is achieved, thus solving the problem of difficulty in controlling the timing and flow rate of pulp output. The work indicator light 14, fixedly connected to the top left side of the equipment frame 1, is electrically connected to the drive motor 201. When the drive motor 201 starts... When the multi-stage crushing mechanism 2 is activated, the working indicator light 14 illuminates; when the drive motor 201 stops working, the working indicator light 14 turns off. Through the electrical connection between the working indicator light 14 and the drive motor 201, the working status of the multi-stage crushing mechanism 2 is displayed intuitively. The shock-absorbing pads 15 are fixedly connected to the four corners at the bottom of the equipment frame 1. The bottom adopts an anti-slip design. When the equipment is running, the shock-absorbing pads 15 absorb the vibration generated by the equipment and reduce the transmission of vibration. The anti-slip design ensures that the equipment is in close contact with the placement surface and prevents the equipment from sliding. The dust cover 16 is rotatably connected to the front side of the carrier plate 9. The handle 17 on the top facilitates opening and closing. When the dust cover 16 is closed, the bottom is magnetically connected to the magnetic block 18 at the front end of the inner side of the sedimentation tank 7 to prevent dust from entering the sedimentation tank 7. The cover plate 19 is rotatably connected to the top and rear end of the feeding trough 5. The bottom of the cover plate is attached to the top of the feeding trough 5 to block dust when no material is being fed.

[0038] Working principle: Waste cardboard labels are poured into the mixing tank 3 from the feeding trough 5. The multi-stage crushing mechanism 2 inside the mixing tank 3 gradually crushes the waste. At the same time, water is injected into the mixing tank 3 through the water supply pipe 4, mixing with the crushed waste to form pulp. Through the coordinated work of the multi-stage crushing mechanism 2 and the water supply pipe 4, the waste is crushed and made into pulp, thus solving the problem that the waste cannot be directly reused. The water pump 6 on the bottom right side of the equipment frame 1 is started. Its input end is connected to the bottom right side of the mixing tank 3, which draws out the pulp from the mixing tank 3 and delivers it to the sedimentation tank 7 on the top left side of the equipment frame 1 through the output end. After the pulp enters the settling tank 7, the settling filter 8 intercepts the fibrous material in the pulp, while the water flows through the settling filter 8 to the other side. Through the cooperation of the water pump 6 and the settling filter 8, the pulp is transported to the settling tank 7 and the fibers are settled, thus solving the problem of the fibers being difficult to concentrate. The water pump 10 on the rear support plate 9 at the top of the equipment frame 1 is started. Its input end is connected to the rear side inside the settling tank 7, and the water settled behind the filter is extracted and transported back to the top rear side of the mixing tank 3 through the output end. The water returned to the mixing tank 3 is mixed with the newly added waste and water again for the next round of processing.

[0039] Furthermore, after the drive motor 201 starts, its output end drives the stirring shaft 202 to rotate inside the mixing tank 3. Two crushing blades 203 on the upper part of the outer wall of the stirring shaft 202 rotate at high speed with the stirring shaft 202, initially crushing the cardboard label waste entering the mixing tank 3 from the feeding trough 5. Larger pieces of waste are broken down into smaller pieces by the impact and cutting of the crushing blades 203. Through the cooperation of the drive motor 201 and the crushing blades 203, the initial crushing effect of the waste is achieved, thus solving the problem of large pieces of waste being difficult to handle. After the initial crushing, the waste fragments fall into the area between the coarse filter screen 205 and the fine filter screen 206. At this time, multiple cutting blades 204 on the lower part of the outer wall of the stirring shaft 202 continue to perform secondary cutting on the waste, further chopping the fragments into smaller pieces. The coarse filter 205 and fine filter 206 perform screening. The coarse filter 205 intercepts larger waste fragments, allowing them to continue to be processed by the cutting blade 204. Fragments that meet certain sizes pass through the coarse filter 205. Through the cooperation of the cutting blade 204 and the coarse filter 205, the waste is further refined and initially screened, thus solving the problem of uneven waste fragment size affecting subsequent processing. The waste fragments passing through the coarse filter 205 continue to fall, and the fine filter 206 screens them again. Fragments that do not meet the required size are intercepted by the fine filter 206 and continue to be finely crushed by the cutting blade 204. Fragments that meet the required size pass through the fine filter 206 and mix with the water injected by the water supply pipe 4 to form pulp. Through multi-stage crushing and screening, it is ensured that the waste particles in the final pulp are of uniform size.
