[0002] Recycling of shredded paper in paper production is a complex and multi-step process aimed at converting waste paper into renewable resources. It requires collecting waste paper recovered from recycling points, which can be office paper, newspapers, magazines, etc.

[0003] Shredding waste paper is one of the key steps in waste paper recycling. Existing paper recycling equipment, such as shredders, use double-shaft shearing shredders or single-shaft shredders to tear and shear waste paper into small pieces, which can be further processed into pulp or other products. However, due to the variety of products, especially for multi-layer and thick paper products such as books, impurities, etc., these paper products are prone to adhesion due to humidity and storage environment.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] An embodiment of a paper production shredded paper recycling device of the present invention is as follows Figures 1 to 10 shown.

Paper products can enter the crushing box 210 from the feed port 211 and be discharged from the discharge port 212 after passing through the two crushing shafts 220. Figure 4 As shown, the crushing shaft 220 on the left rotates clockwise, and the crushing shaft 220 on the right rotates counterclockwise.

[0032] The crushing shaft 220 is arranged along the second direction, and the crushing shaft 220 includes a plurality of first shaft segments 230 and a plurality of second shaft segments 250 arranged in sequence along the second direction, and the first shaft segments 230 and the second shaft segments 250 are alternately distributed in sequence in the second direction. The second direction is a horizontal direction, and the second direction is perpendicular to the first direction. The first shaft segment 230 includes a rotating ring 231, a plurality of rolling knives 232 and a plurality of crushing knives 233. The rotating ring 231 can be installed in the crushing box 210 to rotate around the second direction, and the rotating rings 231 correspondingly arranged on the two crushing shafts 220 can rotate towards each other around the second direction. The plurality of rolling knives 232 and the plurality of crushing knives 233 are arranged in sequence around the second direction on the rotating ring 231, and the plurality of rolling knives 232 and the plurality of crushing knives 233 are alternately distributed in sequence around the second direction. In a natural state, the size of the crushing knife 233 in the third direction is greater than the size of the rolling knife 232 in the third direction, and the third direction is perpendicular to the second direction, and the third direction is the radial direction of the rotating ring 231. The multiple crushing knives 233 can be extended and retracted along the third direction on the rotating ring 231. The crushing knife 232 includes a plurality of first knife bodies 234. The plurality of first knife bodies 234 are arranged in sequence along the second direction on the rotating ring 231, and the sizes of the plurality of first knife bodies 234 in the third direction gradually increase.

[0033] The second shaft section 250 includes a rotating wheel 251, and the rotating wheel 251 can rotate with the rotating ring 231 adjacent to it in the second direction. A plurality of annular grooves 252 are provided in the circumferential direction of the rotating wheel 251, and a plurality of first blades 234 and a plurality of annular grooves 252 are provided in one-to-one correspondence. The two crushing shafts 220 are staggered in the second direction, and the first shaft section 230 of one crushing shaft 220 is provided correspondingly to the second shaft section 250 of the other crushing shaft 220 and meshes with each other, so that the first blade 234 on the first shaft section 230 of one crushing shaft 220 can be engaged with the annular groove 252 on the second shaft section 250 of the other crushing shaft 220 and provided correspondingly to the first shaft section 230.

[0034] Specifically, three first blade bodies 234 are provided. The three first blade bodies 234 are arranged on the rotating ring 231 in sequence along the second direction.

[0035] Two first motors 120 are arranged on the bracket 100, and the first motors 120 are energy-saving motors. The two crushing shafts 220 are arranged one by one corresponding to the two first motors 120 respectively. The rotating ring 231 is installed on the output shaft of the corresponding first motor 120 and is driven to rotate by the corresponding first motor 120.

[0036] In this embodiment, a crushing mechanism 200 is provided. When in use, the paper products to be crushed are put into the crushing box 210 from the feed port 211, and the paper products will fall between the two crushing shafts 220. Since the size of the crushing knife 233 in the third direction is larger than the size of the rolling knife 232 in the third direction, the paper products falling between the two crushing shafts 220 will first be preliminarily crushed by the crushing knife 233 in a natural state, and as the rotating ring 231 of the two crushing shafts 220 rotates, the paper products are brought into the meshing position of the two crushing shafts 220 by the crushing knife 233, and the rolling knife 232 will be engaged with the annular groove 252 at this time, and the crushing knife 233 will also retract along the third direction until it can be engaged with the annular groove 252, so as to further crush and crush the paper products. Furthermore, since the multiple first blade bodies 234 of the rolling knife 232 are sequentially arranged on the rotating ring 231 along the second direction, and the sizes of the multiple first blade bodies 234 in the third direction gradually increase, that is, the diameters of the multiple first blade bodies 234 increase sequentially in the second direction, when the rotating ring 231 drives the multiple first blade bodies 234 to rotate, due to the different diameters of the multiple first blade bodies 234, the linear speeds of the multiple first blade bodies 234 when they are engaged with the corresponding annular grooves 252 are also different. Furthermore, during the crushing process, when the paper products are in contact with the first blade bodies 234 and the annular grooves 252 corresponding to the first blade bodies 234, the multiple first blade bodies 234 will cooperate with the corresponding annular grooves 252 to form a certain speed difference on the paper products, apply force to the local position of the paper products, change the surface contact into line contact and point contact, and then rub multiple layers of thicker or wetter paper products so that they can be separated as much as possible, thereby improving the uniformity of paper product crushing.

[0037] Furthermore, a recovery box 110 is disposed on the support 100 , and the recovery box 110 is used to receive the shredded paper discharged from the discharge port 212 .

[0038] In this embodiment, the first shaft section 230 also includes a fixed disk 235, which is arranged along the second direction and fixedly installed in the crushing box 210. The rotating ring 231 can be rotatably installed on the fixed disk 235 around the second direction. An arc groove 236 is opened on the fixed disk 235 around the second direction. The arc grooves 236 on the two crushing shafts 220 are arranged face to face in the first direction, and the arc grooves 236 are inclined around both ends in the second direction, so that the crushing knife 233 can slide from the fixed disk 235 into the arc groove 236, and slide along the arc groove 236 to return to the fixed disk 235.

[0039] By setting the fixed plate 235, when the rotating ring 231 drives the crushing knife 233 to rotate, when the crushing knife 233 rotates to the meshing position of the two crushing shafts 220, the crushing knife 233 on any crushing shaft 220 can be retracted into the arc groove 236 and slide along the arc groove 236 under the impetus of the annular groove 252 on the other crushing shaft 220 correspondingly set.

[0040] In this embodiment, the second shaft section 250 also includes a fixed shaft 253, which is fixedly connected to a fixed disk 235 adjacent to it in the second direction. The rotating wheel 251 is rotatably mounted on the fixed shaft 253 and is fixedly connected to a rotating ring 231 adjacent to it in the second direction, so that the rotating wheel 251 can rotate along with the rotating ring 231 adjacent to it in the second direction.

[0041] In this embodiment, the crushing knife 233 includes a plurality of second knife bodies 237, and the plurality of second knife bodies 237 are arranged in sequence along the second direction on the rotating ring 231. The plurality of second knife bodies 237 can be respectively extended and retracted along the third direction on the rotating ring 231, and the plurality of second knife bodies 237 are arranged one by one with the plurality of first knife bodies 234.

[0042] Furthermore, a plurality of arc blocks 238 are arranged in the arc groove 236 around the second direction, and the plurality of arc blocks 238 are arranged in sequence along the second direction in the arc groove 236, and a limiting groove 239 is defined between every two arc blocks 238 adjacently arranged along the second direction, and the sizes of the plurality of limiting grooves 239 in the third direction gradually increase, and the plurality of limiting grooves 239 are arranged one by one corresponding to the plurality of second blades 237, and each second blade 237 can be retracted in the third direction to abut against the corresponding limiting groove 239, and the size of the second blade 237 in the third direction after abutting against the limiting groove 239 is equal to the size of the corresponding first blade 234 in the third direction.

[0043] In this embodiment, the crushing knife 233 is provided with a plurality of independently retractable second knife bodies 237, and the waste paper of different thicknesses and shapes is evenly shredded by utilizing the retraction of each second knife body 237. When the second knife body 237 is engaged with the annular groove 252, the second knife body 237 can be retracted to the same length as the first knife body 234 correspondingly arranged around the second direction, so that the first knife body 234 and the second knife body 237 can jointly complete the rubbing of the paper product.

[0044] In this embodiment, each first blade body 234 is provided with a stopper 240 at both ends in the second direction, and each second blade body 237 is provided with a clamping block 241 at both ends in the second direction, and the stopper 240 is located on the side of the clamping block 241 away from the rotating ring 231 in the third direction, and the clamping block 241 can abut against the stopper 240 connected to it and arranged in the second direction.

[0045] In this embodiment, the second blade 237 can be limited by setting a stopper 240 and a clamping block 241. After the second blade 237 is retracted to the arc groove 236, when the second blade 237 is thrown out under the centrifugal force of the rotating ring 231, the stopper 240 can block the clamping block 241 to prevent the second blade 237 from falling out.

[0046] Furthermore, a roller 242 is rotatably provided on each second blade body 237 . The roller 242 is located on a side of the second blade body 237 close to the rotating ring 231 in the third direction and is rotatably matched with the outer peripheral wall surface of the fixed disk 235 .

[0047] By providing the roller 242 , the second blade body 237 and the fixed plate 235 are rotationally matched to reduce the friction between the second blade body 237 and the fixed plate 235 .

[0048] In this embodiment, a feed box 260 is arranged on the crushing box 210, and a feed port 211 is opened on the feed box 260. The feed box 260 can reciprocate along a fourth direction, and the fourth direction is a vertical direction. The feed box 260 includes a first feed plate 261 and a second feed plate 262. The first feed plate 261 and the second feed plate 262 are both provided with a clamping plate 263. The two clamping plates 263 are arranged face to face in the first direction and can move away from or approach each other in the first direction.

[0049] Specifically, mounting grooves are provided on the first feed plate 261 and the second feed plate 262, and a hydraulic telescopic cylinder 264 is provided in each mounting groove. The clamping plate 263 is fixedly connected to the output end of the hydraulic telescopic cylinder 264. The hydraulic telescopic cylinder 264 can drive the clamping plate 263 fixed thereto to move, so that the two clamping plates 263 can move away from or approach each other in the first direction.

[0050] More specifically, both ends of the feed box 260 along the second direction are provided with a driving mechanism 270, the driving mechanism 270 is used to drive the feed box 260 to reciprocate along the fourth direction, and the driving mechanism 270 includes a second motor 271, an eccentric wheel 272 and a sliding frame 273. The second motor 271 and the sliding frame 273 are both installed on the crushing box 210, the second motor 271 is an energy-saving motor, the eccentric wheel 272 is fixedly installed at the output end of the second motor 271, and a sliding groove arranged along the fourth direction is provided on the sliding frame 273. Both ends of the feed box 260 along the second direction are provided with a slider 213, the slider 213 is slidably installed in the slider, and the eccentric wheel 272 is rotatably connected to the slider 213 through a crank.

[0051] The eccentric wheel 272 is driven to rotate by the motor, and the rotation of the eccentric wheel 272 drives the slider 213 to move in the fourth direction in the slide slot through the crank, thereby causing the feed box 260 to reciprocate in the fourth direction.

[0052] In this embodiment, a feed box 260 is provided, and the feed box 260 can reciprocate along the fourth direction, so that the clamping plates 263 on the feed box 260 can approach each other to clamp the paper products. When in use, when a larger paper product is put into the crushing box 210 from one side of the feed box 260, the hydraulic telescopic cylinder 264 is started to drive the two clamping plates 263 to approach each other in the first direction to clamp the paper product, and at the same time, the motor is started to drive the feed box 260 to reciprocate along the first direction, pull the paper product, and apply tension to the paper product, so that the paper product is gradually broken and reduced by the two crushing shafts 220 during the reciprocating movement along the fourth direction, preventing the paper product from being too large so that the paper product cannot be broken at one time, improving the breaking effect, and making the paper product broken more evenly. In addition, during the reciprocating movement of the feed box 260 along the first direction, a certain vibration will be generated on the feed box 260 to assist in the unloading of the paper product.

[0053] In combination with the above embodiments, the specific working process is as follows:

[0054] When in use, the paper products to be crushed are put into the crushing box 210 from the feed port 211, and the paper products will fall between the two crushing shafts 220, and then the two first motors 120 are started. The two first motors 120 will respectively drive the rotating rings 231 of the corresponding crushing shafts 220 to rotate around the second direction.

[0055] Since the size of the crushing knife 233 in the third direction is larger than the size of the rolling knife 232 in the third direction, the paper products dropped between the two crushing shafts 220 will be initially crushed by the crushing knife 233, and as the rotating ring 231 of the two crushing shafts 220 rotates, the paper products are brought into the meshing position of the two crushing shafts 220 by the crushing knife 233. At this time, the rolling knife 232 will be engaged with the annular groove 252, and the crushing knife 233 will also retract along the third direction until it can be engaged with the annular groove 252, so as to further crush and grind the paper products. Furthermore, since the multiple first blade bodies 234 of the rolling knife 232 are sequentially arranged on the rotating ring 231 along the second direction, and the sizes of the multiple first blade bodies 234 in the third direction gradually increase, that is, the diameters of the multiple first blade bodies 234 increase sequentially in the second direction, when the rotating ring 231 drives the multiple first blade bodies 234 to rotate, due to the different diameters of the multiple first blade bodies 234, the linear speeds of the multiple first blade bodies 234 when they are engaged with the corresponding annular grooves 252 are different, and thus in the crushing process, when the paper products are in contact with the first blade bodies 234 and the corresponding annular grooves 252 of the first blade bodies 234, the multiple first blade bodies 23 The ring groove 252 corresponding to the second blade 237 is matched with the second blade 237 to form a certain speed difference on the paper product, so as to apply force to the local position of the waste paper, change the surface contact characteristics into line contact and point contact characteristics, and then rub the multiple layers of thick or relatively wet paper products to separate them as much as possible. When the second blade 237 is engaged with the ring groove 252, the second blade 237 can be retracted to the same length as the first blade 234 corresponding to the second direction, so that the first blade 234 and the second blade 237 can jointly rub the paper products, improve the uniformity of the paper product shredding, and the shredded paper discharged from the discharge port 212 falls into the recycling box 110 for collection.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
