Technical Field

[0001] The invention relates to a waste paper recycling and crushing device, and in particular to a waste paper recycling and crushing device used in the field of waste paper recycling processing. Background Art

[0002] Waste paper recycling has multiple values ​​and necessities. Its core functions include reducing forest resource consumption (every ton of waste paper recycled produces 0.8 tons of recycled paper fiber, equivalent to saving the felling of 17 mature trees and reducing landfill space by 3 cubic meters), reducing environmental pollution (waste paper pulping consumes 40% to 70% less energy than virgin wood pulp, while also reducing wastewater discharge and harmful gases such as methane produced by incineration by 75%), and replacing raw materials (recycled paper can directly replace virgin wood pulp, saving mineral resources such as quartz sand and soda ash, and reducing dependence on ore and wood).

[0003] Through systematic recycling, waste paper is transformed from waste into a high-value resource, achieving sustainable development goals at the ecological, economic and social levels.

[0004] When recycling waste paper, in order to facilitate the subsequent processing of the waste paper, personnel will use a shredding device to shred it.

During shredding, the fan blades can be used to blow the waste paper adsorbed on the first filter plate and the second filter plate upward so that it is cut by the cutting knife, and it can also prevent the waste paper from blocking the filter holes on the first filter plate and the second filter plate, ensuring that the shredded waste paper passes through the first filter plate and the second filter plate smoothly. At the same time, the cut waste paper can be further cut to further improve the degree of shredding of the waste paper and optimize the effect of the device in treating waste paper.

[0008] As a further improvement of the present invention, the aperture of the first filter plate is larger than the aperture of the second filter plate, and there is a gap between the upper side of the sector and the lower side of the second filter plate.

[0009] As a further improvement of the present invention, one end of the rotating shaft away from the energy-saving motor is rotatably inserted into the inner wall of the crushing box, and a sealing cover is placed on the upper end of the crushing box.

After the waste paper is put into the crushing box, the waste paper is pre-crushed by the cutting blade above the first filter plate, and the metal in the waste paper is adsorbed on the magnetic coating 1 to achieve the purpose of separating the metal from the waste paper. Then, the cutting blade under the first filter plate is used to crush the waste paper that has undergone pre-crushing again to improve the degree of waste paper crushing. During crushing, the fan blade can be used to blow the waste paper adsorbed on the first filter plate and the second filter plate upward so that it can be cut by the cutting blade. It can also prevent the waste paper from blocking the filter holes on the first filter plate and the second filter plate, ensuring that the crushed waste paper passes through the first filter plate and the second filter plate smoothly. At the same time, the cut waste paper can be further cut, further improving the degree of waste paper crushing and optimizing the waste paper processing effect of the device.

When the present invention is in use, the elastic force of the spring enables a pair of adjacent squeezing blocks to squeeze the cutting blade, thereby promptly removing the metal adsorbed on the cutting blade, thereby preventing the metal separated from the waste paper from falling off the cutting blade and mixing with the waste paper again due to friction between the cutting blade and the waste paper during cutting, thereby ensuring the smooth progress of subsequent crushing work. Finally, the metal separated from the waste paper is collected in a collection box, thereby improving the convenience of personnel in collecting metals. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Two embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-4 A waste paper recycling and shredding device is shown, comprising a shredding box 1, with a first filter plate 2 and a second filter plate 3 fixedly connected thereto. A feed port is provided at the upper end of the shredding box 1, and a mounting slot is provided therein. A pair of energy-saving motors 4 are fixedly connected thereto. A rotating shaft 5 is fixedly connected to the output end of the energy-saving motor 4, and a plurality of cutting blades 6 are fixedly connected to the outer end of the rotating shaft 5. A pair of side ends of the cutting blades 6 are both coated with a magnetic coating 7, with only the outer ends of the cutting blades 6 located above the first filter plate 2 having the magnetic coating 7.

[0034] A plurality of vertical rods 12 are fixedly connected to the inner bottom wall of the crushing box 1, and an energy-saving motor 2 13 is fixedly connected to the upper end of the vertical rod 12. A plurality of fan blades 14 are fixedly connected to the output end of the energy-saving motor 2 13. When the shredded waste paper passes through the second filter plate 3 and falls onto the fan blades 14, the fan blades 14 can be started to continue shredding the waste paper.

[0035] The aperture of the first filter plate 2 is larger than that of the second filter plate 3. A gap exists between the upper side of the fan blade 14 and the lower side of the second filter plate 3. The end of the rotating shaft 5 away from the energy-saving motor 4 is rotatably inserted into the inner wall of the crushing box 1. A sealing cover 15 is placed on the upper end of the crushing box 1.

[0036] A pair of reinforcement grooves 31 are formed at the upper end of the crushing box 1. A pair of reinforcement rods 32 are fixedly connected to the lower end of the sealing cover 15 and are movably inserted into the reinforcement grooves 31. When the sealing cover 15 is placed on the upper end of the crushing box 1 to seal the feed port, the reinforcement rods 32 will be inserted into the reinforcement grooves 31. The reinforcement rods 32 can limit the sealing cover 15, thereby improving its stability at the upper end of the crushing box 1 and preventing it from moving horizontally at the upper end of the crushing box 1.

[0037] There is a gap between the cutting blade 6 and the inner top wall of the crushing box 1. An observation port is fixedly connected to the side end of the crushing box 1. A rectangular plate 33 is fixedly connected to the inside of the observation port. The rectangular plate 33 is made of transparent material. During the cutting process, the rectangular plate 33 allows personnel to observe the crushing of waste paper.

[0038] A paper taking-out opening 30 is provided at a side end of the crushing box 1 , and a disassembly plate 16 is fixedly connected to the inside of the paper taking-out opening 30 by means of bolts.

[0039] The present invention is divided into the following steps when used:

[0040] Step 1: Start a pair of energy-saving motors 4 to rotate a pair of rotating shafts 5, respectively, to drive the cutting blades 6 thereon, and then remove the sealing cover 15 from the crushing box 1 to expose the feed port, and then put the waste paper into the crushing box 1 through the feed port;

[0041] The waste paper is initially cut using a cutting blade 6 located above the first filter plate 2. During the cutting process, the magnetic coating 7 on the outer end of the cutting blade 6 absorbs the metal in the waste paper, thereby separating the waste paper from the metal. After the waste paper is cut into a certain size, it passes through the first filter plate 2 and moves downward.

[0042] Step 2: After the waste paper has been screened and shredded and passes through the first filter plate 2 and moves downward, it is cut again by the cutting blades 6 below the first filter plate 2 (the distance between a pair of adjacent cutting blades 6 below the first filter plate 2 is smaller than the distance between a pair of adjacent cutting blades 6 above the first filter plate 2, so that the waste paper can be cut into smaller pieces during the second shredding process), thereby improving the degree of shredding of the waste paper;

[0043] After the waste paper is shredded again, it will pass through the second filter plate 3 and fall onto the inner bottom wall of the shredding box 1. After the shredding is completed, the disassembly plate 16 is removed from the paper removal port 30, and the shredded waste paper accumulated on the inner bottom wall of the shredding box 1 can be taken out.

[0044] Step 3: When the waste paper is adhered to the upper surfaces of the first filter plate 2 and the second filter plate 3 and the cutter 6 fails to crush it, the energy-saving motor 2 13 can be started to drive the fan blade 14 to rotate, generating an upward wind force, which blows the waste paper adhered to the upper surfaces of the second filter plate 3 and the first filter plate 2 and the waste paper being cut that is accumulated on the two upwards, so that the cutter 6 can cut the waste paper adhered to the first filter plate 2 and the second filter plate 3, and cut the cut waste paper again, thereby preventing the filter holes on the first filter plate 2 and the second filter plate 3 from being blocked due to larger waste paper adhered to the first filter plate 2 and the second filter plate 3, and further improving the degree of waste paper crushing, optimizing the effect of waste paper crushing. After the waste paper is cut, the operation in step 2 is repeated, and the waste paper is taken out of the crushing box 1 for processing in other steps.

[0045] To sum up, when the present invention is in use, after the waste paper is put into the crushing box 1, the waste paper is pre-crushed by the cutting knife 6 above the first filter plate 2, and the metal in the waste paper is adsorbed on the magnetic coating 7 to achieve the purpose of separating the metal from the waste paper. Thereafter, the cutting knife 6 below the first filter plate 2 is used to crush the waste paper that has been pre-crushed again to improve the degree of crushing of the waste paper. During crushing, the fan blades 14 can be used to blow the waste paper adsorbed on the first filter plate 2 and the second filter plate 3 upward so that it is cut by the cutting knife 6, and it can also prevent the waste paper from blocking the filter holes on the first filter plate 2 and the second filter plate 3, ensuring that the crushed waste paper passes through the first filter plate 2 and the second filter plate 3 smoothly. At the same time, the cut waste paper can be further cut to further improve the degree of waste paper crushing and optimize the effect of the device in treating waste paper.

[0046] The second implementation method:

[0047] This embodiment adds the following structure based on the first embodiment, and the rest of the structure remains the same as the first embodiment, as follows:

[0048] Figure 5-10 It is shown that a plurality of rectangular blocks 8 are fixedly connected to the inner wall of the crushing box 1, and a support rod 9 is movably inserted into the interior of the rectangular block 8. An extrusion block 10 is fixedly connected to the end of the support rod 9 away from the rectangular block 8. A spring 11 is fixedly connected between the extrusion block 10 and the rectangular block 8. When the extrusion block 10 moves, it will drive the support rod 9 to move together. The support rod 9 can improve the stability of the extrusion block 10 and the spring 11 when moving. The spring 11 is movably sleeved on the outer end of the support rod 9.

[0049] An elastic cloth 24 is fixedly connected to the mutually adjacent sides of the pair of extrusion blocks 10. A V-shaped groove is formed between the pair of extrusion blocks 10. A slide plate 25 is slidably connected to the interior of the extrusion block 10. A protrusion 26 is fixedly connected to the side of the slide plate 25. The side of the protrusion 26 away from the slide plate 25 abuts against the side of the elastic cloth 24. A plurality of first elastic ropes 27 and a second elastic rope 28 are fixedly connected to the upper and lower sides of the slide plate 25, respectively. The upper end of the first elastic rope 27 is fixedly connected to the inner top wall of the extrusion block 10. The lower ends of the plurality of second elastic ropes 28 are fixedly connected to the same pulling plate 29. The mutually adjacent sides of the pair of pulling plates 29 are both coated with a magnetic coating 34.

[0050] A plurality of discharge holes 17 are provided on the inner side wall of the crushing box 1. A collection box 18 is placed on the side end of the crushing box 1. A pair of side ends of the collection box 18 are fixedly connected to vertical plates 19. The internal threads of the vertical plates 19 are connected to fixed rods 23. One end of the fixed rod 23 is threadedly connected to the interior of the crushing box 1. A docking port 20 is provided on the end of the collection box 18 close to the crushing box 1.

[0051] The docking port 20 is connected to the discharge hole 17. The end of the fixing rod 23 away from the crushing box 1 extends from the vertical plate 19 and extends to the outside. The ends of the pair of extrusion blocks 10 that are close to each other are both inclined structures, and the inclination direction is from top to bottom. In the initial state, the side ends of the pair of extrusion blocks 10 are in contact, and there is a gap between the extrusion blocks 10 and the rectangular block 8.

[0052] A feeding port 21 is provided at the upper end of the collecting box 18, and a plug-in cover 22 is movably inserted inside the feeding port 21. In the initial state, the spring 11 is in a contracted state, so under the action of the spring 11, it will push a pair of extrusion blocks 10 so that their side ends are in contact near the bottom.

[0053] The present invention is divided into the following steps when used:

[0054] Step 1: After the metal in the waste paper is adsorbed on the cutting blade 6, as the cutting blade 6 rotates, it will gradually insert between the pair of extrusion blocks 10 and push the pair of extrusion blocks 10 to move away from each other, so that the spring 11 will continue to contract between the extrusion block 10 and the rectangular block 8. At this time, under the action of the elastic force of the spring 11, it will push the pair of extrusion blocks 10 and the elastic cloth 24 to squeeze the outer end of the cutting blade 6, thereby increasing the friction between the extrusion block 10 and the elastic cloth 24 and the cutting blade 6, so as to remove the metal adsorbed on the outer end of the cutting blade 6. The bottom of the V-shaped groove formed between the pair of extrusion blocks 10 is an inclined structure, and the inclination direction is downward from front to back. Therefore, the metal separated from the cutting blade 6 will roll into the discharge hole 17 along the inclination direction of the V-shaped groove;

[0055] As the cutting blade 6 rotates, it separates from the extrusion block 10 and the elastic cloth 24, and in the process of continuing to rotate downward, the magnetic coating 1 7 on it will be adsorbed by the magnetic coating 2 34 on the pulling plate 29. After adsorption, the cutting blade 6 drives the pulling plate 29 to move downward together. When the pulling plate 29 moves downward, it will sequentially drive the second elastic rope 28, the slide plate 25 and the first elastic rope 27 to move downward, thereby causing the protrusion 26 to move downward in contact with the elastic cloth 24. The protrusion 26 is used to push the elastic cloth 24, causing the elastic cloth 24 to produce a peristaltic effect, so that the metal adhering to the elastic cloth 24 is separated from the elastic cloth 24, promoting the metal objects in the V-shaped groove to move toward the discharge hole 17, thereby improving the collection efficiency of the collection box 18 for the metal objects;

[0056] Step 2: The discharge hole 17 is connected to the docking port 20, so that the metal that rolls from the extrusion block 10 and the elastic cloth 24 into the discharge hole 17 will enter the docking port 20 under the action of inertia, and then pass through the docking port 20 into the collection box 18. Finally, the plug-in cover 22 on the collection box 18 is removed, and the metal collected in the collection box 18 can be taken out.

[0057] To sum up, when the present invention is in use, the elastic force of the spring 11 can enable the adjacent pair of squeezing blocks 10 and the elastic cloth 24 to squeeze the cutting knife 6, and promptly remove the metal adsorbed on the cutting knife 6, to prevent the metal separated from the waste paper from falling off the cutting knife 6 and mixing with the waste paper again due to the friction between the cutting knife 6 and the waste paper during cutting, thereby ensuring the smooth progress of the subsequent crushing work, and then using the protrusion 26 to push the elastic cloth 24 so that the metal is separated from the elastic cloth 24, and finally using the collection box 18 to collect the metal separated from the waste paper, so as to improve the convenience of personnel in collecting metal.
