As a recyclable resource, its effective recycling and utilization is of great significance for saving resources and reducing environmental pollution. In the recycling and regeneration process, it is gradually divided into processes such as crushing, pulping, and purification;

[0003] In the existing recycling and regeneration process, the cardboard needs to be crushed and then transported for other steps. However, after being crushed, the cardboard is in a piled and fluffy state, which is not convenient for transmission and will occupy a large storage space by itself, resulting in a reduction in the overall efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the prior art that after the cardboard is crushed, it is in a piled and fluffy state, which is not convenient for transmission and will occupy a large storage space by itself, resulting in a reduction in the overall efficiency, and to propose an environment-friendly waste recycling and regeneration device for grey cardboard.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An environment-friendly waste recycling and regeneration device for grey cardboard, including a crushing component for crushing the cardboard. The crushing component includes a feeding box and two crushing rollers, and both of the two crushing rollers are rotatably arranged inside the feeding box;

[0007] A compaction component for compacting the crushed cardboard. The compaction component is located below the feeding box. The crushing component includes a bottom box and two baffles. Both ends of the bottom box are provided with openings, and the two baffles are respectively rotatably arranged at the two openings, and torsion springs are arranged at the rotation points. A pressing plate is slidably arranged inside the bottom box, and both sides of the top of the bottom box are fixedly provided with top plates. The bottom end of the feeding box is fixedly arranged in the middle of the top of the bottom box.

[0008] In a possible design, the crushing component further includes a first servo motor installed on one side of the feeding box. The rotating shafts of the two crushing rollers both rotatably penetrate through the feeding box. The output shaft of the first servo motor is fixedly arranged at the end of one of the rotating shafts, and gears are fixedly sleeved on the outer walls of the two rotating shafts, and the two gears are meshed with each other.

[0009] In a possible design, the compaction assembly further includes two groups of limiting plates, which are respectively arranged at both ends of the bottom box. Each group of limiting plates has two, and the two limiting plates respectively slide through both sides of the bottom box. The side of the limiting plate located inside the bottom box and close to the middle is set as an inclined surface, and the inclined surface cooperates with the pressing plate. The side of the limiting plate located outside the bottom box and close to the baffle is fixedly provided with a mounting plate, and a clamping rod is fixedly provided on the side of the mounting plate close to the baffle. Slots are respectively opened at the tops of both sides of the baffle, and the two slots respectively cooperate with the two adjacent clamping rods.

[0010] In a possible design, both ends of both sides of the compaction assembly are fixedly provided with side boxes, and one end of the limiting plate is located inside the side box. A plurality of sliding rods are fixedly provided on one inner wall of the side box, and the limiting plate is slidably sleeved on the outer wall of the sliding rod. A compression spring is sleeved on the outer wall of the sliding rod, and both ends of the compression spring are respectively fixedly provided on one side of the limiting plate and one inner wall of the side box.

[0011] In a possible design, a side plate is fixedly provided on one side of the bottom box, a second servo motor is fixedly provided on the top of the side plate, a threaded rod is rotatably provided on one side of the side plate, and the other end of the threaded rod is fixedly provided with the output shaft of the second servo motor. A sliding hole is opened on the side of the bottom box close to the second servo motor. A connecting plate is fixedly provided on one side of the pressing plate, and the connecting plate extends to the outside of the bottom box through the sliding hole. The connecting plate is threadedly sleeved on the outer wall of the threaded rod.

[0012] In a possible design, limiting sliding grooves are respectively opened on both inner walls of the bottom box. Sliding blocks are respectively fixedly provided on both sides of the pressing plate, and the two sliding blocks are respectively slidably arranged inside the two limiting sliding grooves.

[0013] In the present application, when used specifically, cardboard is added to the inside of the feeding box, and the rotation of the two crushing rollers is realized through the cooperation of the No. 1 servo motor and the two gears, so that the cardboard is crushed, and then enters the inside of the bottom box. When the cardboard is accumulated to a specified amount, the No. 2 servo motor is driven, and the No. 2 servo motor drives the threaded rod to rotate, thereby driving the pressure plate to move through the connecting plate, so that the pressure plate pushes the crushed cardboard aside and squeezes it. At this time, since the baffle is stuck by the card rod and cannot be opened, the cardboard that is crushed into a fluffy state can be gradually compacted. When the pressure plate touches the limit plate, it will squeeze the inclined surface to move the limit plate outward, and the limit plate drives the card rod to move through the mounting plate , so that the card rod is separated from the inside of the card slot, and then the driving pressure plate will push the baffle open and push out the compacted cardboard, and during this period, the broken cardboard continues to fall and will not hinder the normal crushing work. When the compacted cardboard is pushed out, the baffle is reset by the torsion spring, and then the pressure plate is moved out of the range of the limit plate and is located at the original axially symmetrical position. The limit plate is reset by the compression spring, so that the card rod is re-engaged with the card slot to fix the baffle. After that, the second servo motor can be driven in the reverse direction when the crushed cardboard reaches a certain amount next time, and it can be compacted and pushed out from the other side, so that it can be transported in a compacted and extruded state after crushing, thereby saving space and facilitating transportation.

[0014] In the utility model, the environmentally friendly grey cardboard waste recycling and regeneration device can achieve the goal of crushing the cardboard added to the feeding box through the crushing component, so that subsequent cleaning and pulping processes can be carried out;

[0015] In the utility model, the environmentally friendly grey cardboard waste recycling and regeneration device can achieve the goal of compacting the cardboard after it is crushed, and push it out, and can carry out normal material receiving work during the compaction period. By compacting the originally crushed and fluffy cardboard, the original inconvenience of transportation and the phenomenon of occupying space can be avoided, thereby increasing practical help;

[0016] In the utility model, when in use, the cardboard is crushed by the crushing assembly and then sent into the bottom box for compaction. When the crushed cardboard enters the bottom box and accumulates to a certain extent, the pressing plate can be driven to move for compaction. After compaction, the side baffle can automatically open and push the cardboard out, and normal material receiving work can be carried out during the compaction, thereby solving the inconvenience of transportation caused by the existing crushed cardboard and the phenomenon of occupying a large space due to the fluffyness.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Embodiment 1

[0024] Refer to Figure 1-2 , a recycling and regeneration device, which is used in the field of waste recycling and regeneration, and includes: a crushing component and a compaction component.

[0025] The crushing component 2 is composed of a feeding box 3 and two crushing rollers 4. The feeding box 3 is designed as a box body with an opening for receiving the grey cardboard waste to be processed. The two crushing rollers 4 are installed inside the feeding box 3 through bearings, and the rotating shafts of the two rollers penetrate the side wall of the feeding box 3. To achieve the synchronous rotation of the two rollers, a first servo motor 6 is installed on one side of the feeding box 3, and its output shaft is fixedly connected to the rotating shaft of one of the crushing rollers 4. At the same time, gear 5 is fixedly sleeved on the outer walls of the rotating shafts of the two rollers respectively, and the two gears 5 are meshed with each other to ensure that the two rollers rotate in opposite directions, thereby effectively crushing the cardboard.

[0026] This application can be used in the field of waste recycling and regeneration, and can also be used in other fields applicable to this application.

[0027] Embodiment 2

[0028] Refer to Figure 3-4, improved based on Embodiment 1: An environmentally friendly grey cardboard waste recycling and regeneration device, which is applied to the hospital management field. The compaction component 1 is located below the crushing component 2 and is composed of a bottom box 7, two baffles 8, a pressing plate 12, etc. Both ends of the bottom box 7 are provided with openings. The baffles 8 are installed at the openings through torsion springs and can automatically reset to close the openings. A limit chute 23 is provided inside the bottom box 7. Sliders are installed on both sides of the pressing plate 12, and the sliders slide in the limit chute 23 to ensure the stable movement of the pressing plate 12. On both sides of the top of the bottom box 7, a top plate 9 is fixedly arranged, and a feeding box 3 is fixedly installed in the middle, so that the crushed cardboard can directly enter the compaction area.

[0029] To drive the pressing plate 12 to move up and down, a second servo motor 15 is installed on the side plate 11, and its output shaft is connected to a threaded rod 14. A connecting plate 13 fixed to one side of the pressing plate 12 extends to the outside through a sliding hole 16 on one side of the bottom box 7 and is threadedly sleeved on the outer wall of the threaded rod 14. As the threaded rod 14 rotates, the pressing plate 12 slides in the limit chute 23 accordingly.

[0030] In addition, the compaction component 1 is also provided with two groups of limit plates 21, two in each group, which are respectively located on both sides of both ends of the bottom box 7. One end of the limit plate 21 passes through the side box 10. Side boxes 10 are fixedly arranged at both ends of both sides of the outer wall of the bottom box 7, and the other ends of the four limit plates 21 are respectively located inside the four side boxes 10. A slide rod 17 is arranged inside the side box 10, and the limit plate 21 is slidably sleeved on its outer wall. A compression spring is sleeved on the outer wall of the slide rod 17 to provide a reset force for the limit plate 21. An inclined surface 22 is arranged on the inner side of the limit plate 21 and cooperates with the pressing plate 12. When the pressing plate 12 touches, it will push the limit plate 21 to move outwards, thereby driving the mounting plate 18 and the clamping rod 20 fixed to the limit plate 21 to move, so that the clamping rod 20 disengages from the clamping groove 19 at the top of the side of the baffle 8, and its fixed state is released.

[0031] Specifically, by adding cardboard into the interior of the feeding box 3, the cardboard is broken by two crushing rollers 4, and then enters the interior of the bottom box 7. When the accumulation reaches the specified amount, the second servo motor 15 is driven to drive the pressing plate 12 to move, so that the pressing plate 12 pushes the crushed cardboard to one side and compresses it. At this time, since the baffle 8 is blocked by the clamping rod 20 and cannot be opened, the cardboard in the fluffy state can be gradually compacted. When the pressing plate 12 touches the limiting plate 21, it will squeeze the inclined surface 22 to make the limiting plate 21 move outwards. The limiting plate 21 drives the clamping rod 20 to move through the mounting plate 18, so that the clamping rod 20 disengages from the interior of the clamping groove 19. Then, by driving the pressing plate 12, the baffle 8 will be pushed open and the compacted cardboard will be pushed out. During this period, the crushed cardboard will fall to the other side of the pressing plate 12 and will not interfere with the normal crushing work. After the compacted cardboard is pushed out, the baffle 8 is reset by the torsion spring. Then, the pressing plate 12 is moved out of the range of the limiting plate 21 and located at the original axisymmetric position. The limiting plate 21 is reset by the compression spring, so that the clamping rod 20 is re-engaged with the clamping groove 19 to fix the baffle 8. Then, when the cardboard after the next crushing reaches a certain amount, the second servo motor 15 can be reversely driven to push and compact it from the other side, so that the cardboard can be transported in a compacted and extruded state after crushing, thereby saving space and facilitating transportation, and solving the problems of inconvenient transportation caused by the existing crushed cardboard and large space occupation caused by fluffiness.

[0032] However, as is well known to those skilled in the art, the working principles and wiring methods of the first servo motor 6 and the second servo motor 15 are common knowledge, and they both belong to conventional means or well-known common sense, so they will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0033] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
