[0002] Corrugated paper is a plate-like material made of noodle paper and corrugated paper formed by corrugating rollers. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. According to the needs of commodity packaging, corrugated cardboard can be processed into single-sided corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer and other corrugated cardboard to protect the goods from vibration or collision during storage and transportation. Three-layer and five-layer corrugated cardboard are commonly used in the production of corrugated boxes.

[0003] More than 80% of the used corrugated paper can be recycled to reuse resources and reduce waste. When recycling, it is usually collected and crushed first, and then pulped and papered. However, some corrugated boxes have sealing nails, which are copper nails, copper-plated iron nails, galvanized iron nails or aluminum nails. The metal nails need to be removed before crushing and pulping, otherwise it will increase the wear of the crushing part of the machine. In the existing technology, this step is generally completed manually, which is time-consuming and labor-intensive, increasing the cost of recycling.

[0004] After searching, the patent document with application number CN202022196063.2 and utility model name "A crushing device for corrugated paper recycling" records: "

[0024] Working principle: ... inject an appropriate amount of water into the stirring and separation bin 2, add the discarded corrugated paper boxes, start the rotating motor 6, and the electromagnet 25 starts to attract the metal nails.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0039] The following is a further description of the corrugated paper box recycling and reuse device of the utility model in conjunction with the accompanying drawings and specific embodiments: Figure 1 As shown, this embodiment comprises a primary crushing bin 1, a primary conveyor belt 4, a secondary crushing bin 5, a secondary conveyor belt 8, a tertiary conveyor belt 10 and a pulping device 12, wherein the primary crushing bin 1 is provided with a feed port at the top, a clamping device 2 and a primary crushing device 3 are provided in the middle from top to bottom, the bottom is located above the primary conveyor belt 4, and the right side is connected to the secondary crushing bin 5, a pressing device 6, a secondary crushing device 7, a secondary conveyor belt 8 and a tertiary conveyor belt 10 are provided in the secondary crushing bin 5, and a pulping device 12 is provided at the outlet of the secondary conveyor belt 8, the pressing device 6 is fixed in the secondary crushing bin 5 by a guide rail, and the pressing device The device 6 and the secondary crushing device 7 are both connected to the end of the primary conveyor belt 4, the secondary conveyor belt 8 and the tertiary conveyor belt 10 are both located at the discharge side of the secondary crushing device 7, and the tertiary conveyor belt 10 is higher than the secondary conveyor belt 8, wherein the secondary crushing device 7 comprises a power device, a secondary crushing roller 7-1 and a crushing knife 7-2, and the crushing knife 7-2 comprises an elastic blade 7-2-1, a hammer block 7-2-2 and an arc blade 7-2-3, one end of the elastic blade 7-2-1 is hinged on the secondary crushing roller 7-1, and the proximal end of the other end is provided with an arc hammer block 7-2-2, and the distal end is provided with an arc blade 7-2-3. A crushing protrusion 7-2-4 is provided on the arc hammer block 7-2-2.

[0040] Figure 1The dotted part in the upper left part represents the corrugated cardboard box 13, which has a feed port at its bottom. The cardboard box falls into the primary crushing box from the feed port and is clamped by the clamping device 2. The clamping device 2 will slowly transfer the cardboard box downward. The clamping device 2 does not crush the corrugated cardboard box 13 like two meshing gears 2-3, but only slightly clamps it during transfer, thereby playing the role of quantitatively conveying the corrugated cardboard box 13 into the lower primary crushing device 3. The corrugated cardboard boxes 13 entering the primary crushing device 3 will be torn and cut into strips little by little, and the long strips of cardboard boxes will fall on the primary conveyor belt 4 below and continue to be transported downward, and enter the secondary crushing bin 5 after passing through the clamping device 6. In the secondary crushing bin 5, the crushing knife 7-2 on the secondary crushing roller 7-1 in the secondary crushing device 7 will break them into small pieces of corrugated cardboard boxes 13 and throw them out. During the rising process, the small pieces of corrugated cardboard boxes 13 mixed with metal nails will have the metal nails with higher specific gravity thrown far away, and the small pieces of corrugated cardboard boxes 13 with lower specific gravity thrown near, so a simple separation phenomenon will be formed at the far end of the throwing path. According to the principle of different resistance of the two in the air, small pieces of corrugated paper boxes 13 are thrown on the secondary conveyor belt 8, and metal nails are thrown on the tertiary conveyor belt 10. The cutting height of the secondary crushing roller 7-1 is adjusted to improve the trajectory of the final throwing after cutting, allowing a part of the small pieces of corrugated paper boxes 13 to fall on the tertiary conveyor belt 10, so that the metal nails with a large specific gravity can be separated more accurately. The metal nails mixed with small pieces of corrugated paper boxes 13 on the tertiary conveyor belt 10 can be screened again by other equipment or manually. After such a setting, most of the metal nails can still be separated efficiently, and the labor effort of manually removing metal nails can still be greatly reduced.

[0041] like Figure 7 and 8As shown, the secondary crushing roller 7-1 is hinged with an elastic blade 7-2-1, and the inner side surface of the end thereof is provided with an arc blade 7-2-3 and a hammer block 7-2-2 from the outside to the inside. When the other end rotates with the secondary crushing roller 7-1, if it hits the corrugated cardboard box 13, it will produce a slight deformation, so that it will not be destroyed by its rebound force, and further throwing force can be achieved on the corrugated cardboard box 13. If there are metal nails on the corrugated cardboard box 13, the hammer block 7-2-2 can first contact the metal nails on the corrugated cardboard box 13, and only after the contact will the arc blade 7-2-3 contact. Slightly lower than the hammer block 7-2-2 is the arc blade 7-2-3, and the corrugated cardboard boxes 13 that cannot be knocked off will be cut twice by the crushing knife 7-2. The hammer block 7-2-2 will smash and crook the cardboard box, or even tear it. There is also a crushing protrusion 7-2-4 on the hammer block 7-2-2. Increasing the roughness on the surface of the hammer block 7-2-2 can knock or tear the corrugated cardboard box 13 into pieces. The arc blade 7-2-3 can also then cut cracks in the corrugated cardboard box 13, so that the corrugated cardboard box 13 completes the cutting action while hammering and tearing. Finally, the corrugated cardboard box 13 is crushed into small cubes, and the arc blade 7-2-3 will not be overly hit by the metal nails, thereby reducing the wear degree of the arc blade 7-2-3. In addition, the probability of the hammer block 7-2-2 hitting the metal nail is much greater than the probability of the arc blade 7-2-3 hitting. Finally, the corrugated cardboard box 13 pieces are turned into fragments under the action of hammering and cutting, and most of them fall on the secondary conveyor belt 8 after flying out and are sent to the pulping device 12 in the next step.

[0042] When the number and thickness of the corrugated paper boxes 13 are relatively large, the housing 6-2 will be pushed up and moved back and forth on the slide rail 6-1 to adapt to the different numbers or thicknesses of the corrugated paper boxes 13. As the narrow strips of corrugated paper boxes 13 are continuously transported downward to the secondary crushing roller 7-1 of the secondary crushing device 7, a crushing knife 7-2 is provided on the secondary crushing roller 7-1, and one end of a plurality of elastic blades 7-2-1 is hinged on the crushing knife 7-2, and the other end of the elastic blade 7-2-1 is provided with a hammer block 7-2-2 and an arc blade 7-2-3 in sequence. The hammer block 7-2-2 realizes hammer-type tearing of the corrugated paper boxes 13, and the arc blade 7-2-3 realizes cutting-type tearing of the corrugated paper boxes 13, and the two cooperate to achieve higher efficiency. After the crushing protrusion 7-2-4 is provided on the hammer block 7-2-2, it can realize a better tearing action on the corrugated paper boxes 13.

[0043] The clamping device 2 comprises a power device, two clamping rollers 2-4 and a clamping protrusion 2-5, wherein the output shaft of the power device drives one clamping roller 2-4, and the other clamping roller 2-4 is connected to the clamping roller 2-4 through two gears 2-3 of equal diameter. The outer ring surfaces of the two clamping rollers 2-4 are provided with clamping protrusions 2-5, and are embedded with each other.

[0044] like Figure 2 As shown, the motor 2-1 drives the reducer 2-2 to drive a clamping roller 2-4 to rotate. The clamping roller 2-4 is provided with a gear 2-3 with the same diameter and meshing with each other on the rotating shaft, which can drive the other clamping roller 2-4 to rotate synchronously, so that the clamping protrusions 2-5 on the two clamping rollers 2-4 can keep overlapping each other without colliding. Figure 3 As shown, the corrugated box 13 is clamped into a curved S shape between the clamping protrusions 2-5 on the two clamping rollers 2-4, but the clamping protrusions 2-5 do not directly crush the corrugated box 13, because when the corrugated box 13 is relatively intact, it needs to overcome greater resistance when directly crushing it, which will cause greater energy consumption of the equipment.

[0045] The primary crushing device 3 comprises a power device, two primary crushing rollers 3-1 and a cutting knife 3-2, wherein the output shaft of the power device drives one primary crushing roller 3-1, and the other primary crushing roller 3-1 is connected to the primary crushing roller 3-1 through a gear 2-3, and the cutting knives 3-2 are arranged on the outer ring surfaces of the two primary crushing rollers 3-1 and are embedded with each other. The tip of the cutting knife 3-2 faces one side of the rotation direction of the primary crushing roller 3-1.

[0046] The corrugated paper box 13 entering the primary shredding device 3 will be torn and cut into strips or bands by the cutting knife 3-2 little by little, and then fall onto the primary conveyor belt 4 below. There is a certain gap between the blades here, so even if they hit the metal nails, they will not be excessively damaged.

[0047] The clamping device 6 comprises a power device, a shell 6-2, a slide rail 6-1 and a clamping roller 6-4, wherein the shell 6-2 is provided with a power device and a clamping roller 6-4, the output shaft of the power device drives the clamping roller 6-4 through a belt 6-3, the shell 6-2 is connected to the inner wall of the secondary crushing bin 5 through the slide rail 6-1, and a feeding protrusion 6-5 is provided on the outer ring surface of the clamping roller 6-4.

[0048] The housing 6-2 of the clamping device 6 is connected to the slide rail 6-1 on the inner wall of the secondary crushing bin 5. The housing 6-2 is provided with a power device, i.e., a combination structure of a motor 2-1 and a reducer 2-2. The motor 2-1 drives the clamping roller 6-4 arranged at the front end of the housing 6-2 to rotate through the reducer 2-2 and the belt 6-3. When the clamping roller 6-4 rotates, the corrugated paper box 13 cut into strips can be pressed downward to become solid, and then clamped between the clamping roller 6-4 and the end of the primary conveyor belt 4, producing a better material-pickling effect. The two clamp the strip-shaped corrugated paper box 13 together and convey it downward to the secondary crushing device 7. Among them, there is a feeding protrusion 6-5 on the top of the clamping roller 6-4, and the surface of the roller and the corrugated paper box 13 are rough and have a large friction. If thicker or more corrugated paper boxes 13 are stacked, the housing 6-2 and the clamping roller 6-4 will be pushed upward and move along the slide rail 6-1. The 13 corrugated boxes can be well clamped and conveyed downward regardless of their thickness.

[0049] The inner wall of the secondary crushing bin 5 is provided with a buffer layer 11 to alleviate the situation where the metal nails are thrown on the inner wall of the secondary crushing bin 5 and rebound back and forth, and may not fall on the tertiary conveyor belt 10. The inner wall of the secondary crushing bin 5 is provided with a dust removal device 9, which includes a water pipe 9-1 and an atomizing nozzle 9-2, and a plurality of atomizing nozzles 9-2 are distributed on the water pipe 9-1.

[0050] The atomizing nozzle 9-2 can atomize water into smaller water droplets. This can greatly reduce the dust in the secondary crushing bin 5. Since the corrugated paper box 13 is sometimes covered with dust, a certain amount of dust will be generated when it is crushed. In addition, when the corrugated paper box 13 is thrown after being crushed, it will absorb the atomized small water droplets, thereby increasing its own weight and accelerating its falling speed.

[0051] The pulping device 12 comprises a power device, a stirring tank 12-1 and a stirring blade 12-2, wherein the power device is fixed at the opening of the stirring tank 12-1 by a bracket, and the output shaft of the power device is connected to the rotating shaft of the stirring blade 12-2. Water and crushed corrugated paper boxes 13 are added to the stirring tank 12-1, and the pulp is gradually stirred into pulp and then discharged to the next step. The power device involved in this scheme may include a motor 2-1 and a reducer 2-2, and the output shaft of the motor 2-1 is connected to the input shaft of the reducer 2-2.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
