DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0016] See also Figures 1 to 11 In an embodiment of the present invention, a waste cardboard box crushing and recycling device with anti-jamming includes a feed box 1 with openings on both end plates, a sliding table 2 is slidably connected in the opening, two crushing tooth rollers 14 are rotatably installed under the inner wall of the feed box 1, a conveying mechanism extending to the inner cavity of the feed box 1 is rotatably installed inside the feed box 1, a guide mechanism for guiding the conveying mechanism is arranged inside the sliding table 2, a transmission mechanism connected to the two sliding tables 2 is installed on one side plate of the feed box 1, a protective box 13 for shielding the slide 47 is installed on one side plate of the sliding table 2, and the output end of the transmission mechanism is connected to the conveyor The feed box 1 is connected to the feed box 1, and a driving mechanism for driving the crushing tooth roller 14 to rotate is installed on the other side plate of the feed box 1. A one-way rotating mechanism connected to the driving mechanism is installed on the other side plate of the feed box 1. The one-way rotating mechanism is connected to the sliding table 2 through a connecting rack 6. Both sides of the top of the sliding table 2 are integrally formed with sliding seats 3. A horizontal guide rod 4 fixedly connected to the end plate of the feed box 1 is slidably installed on the inner wall of the sliding seat 3. A slow-release mechanism is distributed on the outer wall of the horizontal guide rod 4 and the inner wall of the sliding seat 3. A reset spring 5 is abutted between the sliding seat 3 and the feed box 1, and the reset spring 5 is sleeved on the outer periphery of the horizontal guide rod 4.

[0017] In this embodiment: first, when recycling waste paper boxes, the waste paper boxes are fed in from the top opening of the feed box 1, and the paper boxes move downward along the feed box 1 under gravity. At this time, the driving mechanism drives the two crushing tooth rollers 14 to rotate in opposite directions, and the two crushing tooth rollers 14 rotating in opposite directions crush the waste paper boxes. When there is too much feeding, the compressed waste paper boxes are compacted by the two crushing tooth rollers 14 and stuck between the two crushing tooth rollers 14. At this time, the two crushing tooth rollers 14 are stuck and cannot continue to rotate; At this time, the driving mechanism is operated in the reverse direction. When the driving mechanism is operated in the reverse direction, the one-way rotating mechanism is driven to rotate. The rotating one-way rotating mechanism drives the two sliding tables 2 to move toward each other through the connecting rack 6. The two sliding tables 2 moving toward each other drive the sliding seat 3 to slide along the horizontal guide rod 4. At this time, the reset spring 5 is compressed, and the upper part of the transmission mechanism moves toward each other with the sliding table 2, while the transmission mechanism moves downward under the reset force, ensuring that the transmission belt 26 remains in a tensioned state. At this time, the driving motor 20 is started, and the driving motor 20 drives the two sets of conveying wheel assemblies to rotate in the opposite direction through the transmission mechanism; The conveying wheel assembly also moves synchronously with the sliding table 2, so the two sets of conveying wheel assemblies rotating in opposite directions and approaching each other can convey the waste paper boxes located on the outside upwards during the rotation process, so that the stuck waste paper boxes move upwards and fall on the top of the sliding table 2, and separate from the two crushing tooth rollers 14. In the above process, the distance between the two sliding tables 2 gradually decreases; After that, the driving mechanism is rotated forward again, and the driving mechanism drives the two crushing tooth rollers 14 to rotate toward each other again. At this time, the sliding seat 3 is pushed to reset under the reset of the reset spring 5, and the sliding seat 3 slowly resets under the resistance of the slow release mechanism. Therefore, in this process, the distance between the two sliding tables 2 gradually increases, and the waste cardboard boxes located on the top of the sliding table 2 contact with the inner wall of the feed box 1 during the reset of the sliding table 2. The extrusion force formed by the contact makes the waste cardboard boxes located on the top of the sliding table 2 gradually fall down from between the two sliding tables 2, avoiding the problem of the waste cardboard boxes falling down together during the reset of the sliding table 2, thereby avoiding the problem of the crushing tooth rollers 14 being stuck again.

[0018] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6The conveying mechanism includes a conveying wheel assembly rotatably installed inside the sliding table 2. A group of conveying wheel assemblies includes a plurality of axially distributed conveying wheels 21. A groove body for the conveying wheel 21 to rotate is provided inside the sliding table 2. Part of the conveying wheel 21 penetrates the inner cavity of the feed box 1. A plurality of sliding grooves 27 are axially provided inside the conveying wheel 21. A sliding cone 34 is slidably installed inside the sliding groove 27. A push-out spring 35 is fixedly installed between one end of the sliding cone 34 located inside the sliding groove 27 and the closed end of the sliding groove 27. The end of the sliding cone 34 away from the push-out spring 35 is in a pointed cone structure. The guide mechanism includes a pressure rod 29 integrally formed on the outside of the piston plate of the sliding cone 34, and a vertical groove 28 for the pressure rod 29 to slide is opened on one end of the conveying wheel 21, and the vertical groove 28 is connected to the inner cavity of the sliding groove 27; the guide mechanism also includes a guide ring 30 fixedly installed inside the sliding platform 2 and located on the end face of the conveying wheel 21, one side of the inner wall of the guide ring 30 has a first arc 31, and the other side of the inner wall of the guide ring 30 has a second arc 32, the center of the first arc 31 coincides with the center of the second arc 32, and a transition slope 33 is formed between the two ends of the guide ring 30 and the first arc 31.

[0019] In this embodiment, the two groups of conveying wheel assemblies rotate in opposite directions under the drive of the transmission mechanism. During the rotation of the conveying wheel 21, the conveying wheel drives the pressure rod 29 to rotate synchronously. The rotating pressure rod 29 moves along the inner wall extension trajectory of the guide ring 30. When the pressure rod 29 contacts the inner wall of the first arc 31, the sliding cone 34 is completely located inside the sliding groove 27. During the process of the pressure rod 29 gradually contacting the inner wall of the second arc 32 through the transition slope 33 below, the push-out spring 35 is reset. The kinetic energy of the ejection spring 35 is used to push the sliding cone 34 outward, and the pointed cone end of the sliding cone 34 slides out to the inside of the sliding groove 27 and contacts the waste carton. At this time, the pointed cone end with kinetic energy that slides out pierces the waste carton, thereby driving the waste carton to move upward, and the inner carton that is not pierced by the pointed cone end remains in the current position, thereby achieving the purpose of conveying the waste carton upward one by one. As the carton is conveyed upward one by one, the waste carton that goes up first is squeezed by the waste carton that goes up later and falls on the top of the sliding platform 2; When the sliding cone 34 passes through the upper transition slope 33 and contacts the first arc 31 , the compression rod 29 is compressed, driving the ejection spring 35 to be compressed and retracted into the sliding groove 27 again.

[0020] Please refer to Figure 2 and Figure 3The transmission mechanism includes a track 15 fixedly mounted on a side panel of the feed box 1 close to the protective box 13, a slider is slidably mounted on the inner wall of the track 15, one end of the slider is rotatably mounted with a No. 1 pulley 16 through a rotating shaft, one end of the No. 1 pulley 16 is rotatably mounted with a sliding plate 17 through a rotating shaft, and one end of the sliding plate 17 is mounted with a driving motor 20 coaxially connected to the No. 1 pulley 16 through a rotating shaft; the transmission mechanism also includes a No. 2 pulley 22 coaxially connected to a group of conveying wheel assemblies through a synchronous shaft and a connecting gear 23 coaxially connected to another group of conveying wheel assemblies through a synchronous shaft, the No. 2 pulley 22 and the connecting gear 23 are distributed on the outer sides of the two sliding tables 2, the outer side of the connecting gear 23 is meshed with a No. 3 pulley 24 rotatably mounted with the outer side of the feed box 1, and an end plate of the No. 3 pulley 24 A tooth block meshing with the connecting gear 23 is formed on it; the transmission mechanism also includes two guide wheels 25 fixedly mounted on the outside of the feed box 1, and the No. 2 pulley 22, the No. 3 pulley 24 are connected to the No. 1 pulley 16 through a transmission belt 26. The two guide wheels 25 are used to maintain the transmission wrap angle between the transmission belt 26 and the No. 2 pulley 22 and the No. 3 pulley 24, and an opening for the transmission belt 26 is provided on the bottom end plate of the protection box 13; the transmission mechanism also includes two vertical guide rods 19 integrally formed on the bottom plate of the protection box 13, the vertical guide rods 19 pass through the sliding plate 17 and are slidably connected to the sliding plate 17, and an extrusion spring 18 is fixedly installed between the top of the sliding plate 17 and the bottom end of the protection box 13; a slide groove 47 for the sliding of the synchronous shaft is provided on the side plate of the feed box 1 that contacts the synchronous shaft.

[0021] In this embodiment: in the process of the two sliding platforms 2 approaching each other, the second pulley 22 and the connecting gear 23 follow the two sliding platforms 2 to approach each other, at this time, the extrusion spring 18 is reset, the extrusion spring 18 pushes the sliding plate 17, and the sliding plate 17 drives the driving motor 20 and the first pulley 16 to slide downward synchronously, so that the transmission belt 26 is always kept in a tensioned state, and the driving motor 20 is started synchronously, and the driving motor 20 drives the first pulley 16 to rotate, and the first pulley 16 drives the second pulley 22 and the third pulley 24 to rotate synchronously through the transmission belt 26, and the third pulley 24 drives the connecting gear 23 to rotate synchronously in the opposite direction, so the second pulley 22 and the connecting gear 23 achieve the purpose of driving the two sets of conveying wheel assemblies to rotate synchronously in the opposite direction; On the contrary, during the process of the two sliding tables 2 moving in opposite directions, under the pull of the transmission belt 26, the first pulley 16 slides upward, and the extrusion spring 18 is compressed again.

[0022] Please refer to Figure 1The driving mechanism includes a forward and reverse motor 7 installed on the side of the feed box 1 away from the protective box 13. A driving gear 8 is installed on the output end of the forward and reverse motor 7. A driven gear 9 is meshed on the outer periphery of the driving gear 8. The driving gear 8 and the driven gear 9 are respectively coaxially fixedly connected to a crushing tooth roller 14.

[0023] In this embodiment: when the forward and reverse motor 7 rotates forward, the forward and reverse motor 7 drives the driving gear 8 to rotate, and the driving gear 8 drives the driven gear 9 to rotate synchronously in the opposite direction, so that the driving gear 8 and the driven gear 9 rotate in opposite directions, and the driving gear 8 and the driven gear 9 respectively drive the crushing tooth rollers 14 connected thereto to rotate, so that the two crushing tooth rollers 14 rotate synchronously in opposite directions; When the forward and reverse motor 7 rotates in the reverse direction, the two crushing tooth rollers 14 rotate in opposite directions synchronously.

[0024] Please refer to Figure 7 and Figure 8 The one-way rotation mechanism includes two one-way gears 11, one of which is meshed with the driven gear 9 just above, and the other is meshed with the driving gear 8 just below. A rotating shaft 10 rotatably connected to the outside of the feed box 1 is rotatably mounted at the center of the one-way gear 11. One end of the two rotating shafts 10 away from the feed box 1 is coaxially fixedly connected with a driving gear 12. A connecting rack 6 connected to a sliding table 2 is meshed with the outer side of one driving gear 12 at the lower part, and a connecting rack 6 connected to another sliding table 2 is meshed with the outer side of the other driving gear 12 at the upper part. The one-way rotation mechanism also includes a receiving groove 36 opened at the center of the one-way gear 11. The receiving groove 36 is a non-through hole structure. The inner circumference of the receiving groove 36 is integrally formed with a connecting seat 38 protruding toward the center. A ratchet 39 is rotatably installed on the outer side of the connecting seat 38. A torsion spring 48 is clamped at the joint between the connecting seat 38 and the ratchet 39; the one-way rotation mechanism also includes a ratchet 37 integrally formed on the outer circumference of the rotating shaft 10, and a group of ratchet wheels 37 are engaged with a connecting seat 38; the ratchet teeth 39 on the inner circumferences of the two one-way gears 11 face opposite directions, and the ratchet wheels 37 on the outer circumferences of the two rotating shafts 10 face opposite directions.

[0025] In this embodiment: during the forward rotation of the forward and reverse motor 7, the driving gear 8 and the driven gear 9 rotating in opposite directions respectively drive the one-way gear 11 meshing therewith to rotate, and the rotating one-way gear 11 drives the ratchet 39 to follow the movement through the connecting seat 38. At this time, the ratchet 39 contacts the outer inclined surface of the tooth portion of the ratchet wheel 37, and the extrusion force generated by the contact acts on the ratchet 39. The ratchet 39 drives one end of the torsion spring 48 engaged therewith to twist, while the end of the torsion spring 48 engaged with the connecting seat 38 remains stationary. After the ratchet 39 is misaligned with the outer side of the tooth portion of the ratchet wheel 37, the torsion spring 48 can drive the ratchet 39 to reset. Therefore, during the forward rotation of the forward and reverse motor 7, the rotating shaft 10 remains stationary and does not rotate. When the forward and reverse motor 7 rotates in the reverse direction, the driving gear 8 and the driven gear 9 rotating in the opposite direction also drive the one-way gear 11 meshing therewith to rotate. At this time, the rotation direction of the one-way gear 11 changes, so the one-way gear 11 can drive the ratchet 39 to rotate synchronously through the connecting seat 38. At this time, the ratchet 39 clamps the ratchet wheel 37. At this time, the ratchet wheel 37 rotates synchronously with the one-way gear 11. The ratchet wheel 37 can drive the rotating shaft 10 to rotate, and the rotating shaft 10 can drive the driving gear 12 to rotate. At this time, the two driving gears 12 are in a state of rotating in opposite directions, and the driving gear 12 can drive the sliding table 2 to slide through the connecting rack 6.

[0026] Please refer to Fig.10 , Fig.11 The slow-release mechanism includes a triangular groove 40 formed on the outer periphery of the horizontal guide rod 4, and a first extrusion slope 41 is formed at one end of the triangular groove 40 close to the protrusion of the horizontal guide rod 4, and a second extrusion slope 42 is formed at one end of the triangular groove 40 away from the protrusion of the horizontal guide rod 4, and the inclination angle of the second extrusion slope 42 is smaller than the inclination angle of the first extrusion slope 41; the slow-release mechanism also includes a connecting groove 49 formed inside the sliding seat 3, and the second extrusion slope 42 penetrates to the inner wall of the sliding seat 3, and the connecting groove 49 The inner wall is slidably connected with a downwardly protruding triangular block 44, and an elastic member 43 is fixedly installed between the flat portion of the triangular block 44 and the closed end of the inner wall of the connecting groove 49. A first pressure inclined surface 45 is formed on one side of the bottom end of the triangular block 44 protruding close to the horizontal guide rod 4, and a second pressure inclined surface 46 is formed on the other side of the bottom end of the triangular block 44 away from the protruding portion of the horizontal guide rod 4; the first pressure inclined surface 45 coincides with the first extrusion inclined surface 41, and the second pressure inclined surface 46 coincides with the second extrusion inclined surface 42.

[0027] In this embodiment: First, during the reverse rotation of the forward and reverse motor 7, the two connecting racks 6 respectively drive the sliding table 2 connected thereto to move toward each other, and the sliding table 2 drives the sliding seat 3 connected thereto to slide along the horizontal guide rod 4. During the sliding of the sliding seat 3, since its sliding power comes from the rotation speed of the driving gear 12, the sliding speed of the sliding table 2 is not affected by the resistance of the slow-release mechanism. When the forward and reverse motor 7 rotates forward after the reverse rotation is completed, the two one-way gears 11 no longer drive the rotating shaft 10 to rotate during the rotation process, and under the reset force of the reset spring 5, the rotation of the rotating shaft 10 is stopped. , the sliding seat 3 slides along the horizontal guide rod 4 to reset, and the sliding seat 3 that resets and slides can drive the connecting rack 6 to reset and slide. The connecting rack 6 drives the driving gear 12 to rotate in the opposite direction during the reset process. Since the rotation direction of the driving gear 12 is the same as the rotation direction of the ratchet 39 at this time, the two do not interfere with each other during the rotation process, and the rotating ratchet 39 no longer blocks the ratchet wheel 37 at this time. Therefore, the resistance given by the slow release mechanism during the reset process of the resetting sliding seat 3, the rotation speed of the driving gear 12 and the one-way gear 11 formed is inconsistent, and there will be no interference between the ratchet 39 and the ratchet wheel 37. During the resetting process of the sliding seat 3, the sliding seat 3 drives the triangular block 44 to be clamped into the triangular groove 40. At this time, the moving direction is toward the protruding part of the horizontal guide rod 4. Therefore, at this time, the No. 1 extrusion slope 41 is in contact with the No. 1 pressure slope 45. Under the extrusion force, the No. 1 pressure slope 45 pushes the triangular block 44 to retract into the connecting groove 49. At this time, the elastic member 43 is compressed. The resistance formed can reduce the resetting speed of the sliding seat 3, thereby reducing the resetting speed of the sliding table 2, so as to achieve a slow increase in the distance between the two sliding tables 2 instead of a sudden resetting, thereby avoiding the secondary jamming caused by the fall of all the waste cartons; The design of the second extrusion slope 42 and the second pressure slope 46 can reduce the feeding resistance of the sliding seat 3, and the reduced resistance is relative to the reset resistance.

[0028] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
