Description

Technical Field

[0001] The present invention relates to the technical field of carton processing equipment, and particularly to a cardboard cleaning device for carton processing. Background Art

[0002] During the carton processing, the cleanliness of the cardboard surface has an important impact on the quality and performance of the carton. If there are dust, impurities, etc. on the cardboard surface, it will not only affect the printing effect, may reduce the strength and durability of the carton, but also may form a barrier in the bonding process, weaken the adhesive force of the glue, resulting in cracking at the corners of the carton and loose box structure, seriously affecting its load-bearing performance and transportation protection ability, and further affecting the reliability and safety of the entire logistics packaging system. At present, most of the cardboard cleaning devices on the market can only clean one side of the cardboard. If the other side of the cardboard needs to be cleaned, it is necessary to manually turn the cardboard and then clean it again, which not only increases the labor cost, but also reduces the production efficiency. At the same time, the errors in manual operation will also affect the stability of the cleaning effect.

[0003] Chinese Patent CN116586345A announced on August 15, 2023 discloses a cardboard surface cleaning device for carton production. By operating the electric telescopic rod, the connecting frame drives the frame to move downward, and then the first threaded rod drives the movable frame, the convex column, the T-shaped long frame and the inclined plate to move toward the side close to the power motor. During the movement, the first brush and the second brush will respectively clean the upper surface and the lower surface of the cardboard body. However, for this cardboard surface cleaning device for carton production, the cardboard is prone to displacement due to external forces during use, resulting in uneven contact between the cleaning head and the cardboard surface, and there will be cleaning blind spots or over-cleaning situations, affecting the stability of the cleaning quality, and the cooperative operation between components is not tight enough, and the continuity during the cleaning process is poor.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other. Next, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments. Embodiment

[0020] Please refer to Figures 1-13The present invention provides a technical solution: a cardboard cleaning device for carton processing, comprising a workbench 1, a conveying assembly 2 for cardboard feeding is arranged on the top outer wall of the workbench 1, a cardboard body 3 is arranged on the top of the conveying assembly 2, a fixing seat 4 is fixedly installed on the top outer wall of the workbench 1, a supporting seat 5 is fixedly installed on the top outer wall of the fixing seat 4, a limiting groove 6 is provided on the outer wall of the supporting seat 5, a lifting and flipping assembly 7 for driving the cardboard to flip is arranged on the top outer wall of the workbench 1, and the lifting and flipping assembly 7 includes an electric cylinder 725, and the movable end of the electric cylinder 725 is fixedly connected with a telescopic rod 726 The end of the telescopic rod 726 away from the electric cylinder 725 is fixedly connected to the cleaning top plate 727, an electric guide rail 728 is installed on the outer wall of the bottom end of the cleaning top plate 727, a slide rail 729 is fixedly installed on the outer wall of the bottom end of the cleaning top plate 727, the outer side of the slide rail 729 is slidably connected to a sliding seat 730, the bottom end of the sliding seat 730 is fixedly connected to a cleaning machine body 731, the output end of the cleaning machine body 731 is through-connected with a connecting pipe 732, the end of the connecting pipe 732 away from the cleaning machine body 731 is through-connected with a cleaning head 733, and the outer side of the cleaning head 733 is fixedly connected to a filtering scraper 734.

[0021] When in use, the main power of the equipment is turned on, the conveying component 2 is started, and after the cardboard is fixed, the electric cylinder 725 is started, and the cleaning top plate 727 is driven to move downward through the telescopic rod 726, and the notch at one end of the cleaning top plate 727 avoids the driving motor 702 to avoid interference. When the cleaning head 733 contacts the upper surface of the cardboard body 3, the driving power supply supplies power to the electric guide rail 728 and the cleaning machine body 731, and the electric guide rail 728 pushes the sliding seat 730 to move laterally along the sliding rail 729, so that the cleaning head 733 reciprocates on the cardboard surface, and the L-shaped filtering scraper 734 on the outer side of the cleaning head 733 is close to the cardboard surface. After the upper surface is cleaned, the electric cylinder 725 drives the cleaning top plate 727 to reset, the driving motor 702 is reversed, the lifting rod 704 descends, the rack 708 is disengaged from the ratchet 707, and the frame 712 flips 180° to make the lower surface of the cardboard body 3 Face up, repeat the steps of lowering the cleaning top plate 727 and moving the cleaning head 733 to complete the cleaning of the lower surface of the cardboard. The elastic support and clearance design of the push plate 210 ensure seamless connection between the cardboard conveying and flipping processes to avoid mechanical interference. The linear motion of the lifting rod 704 is converted into the flipping motion of the frame 712 through the rack 708-ratchet 707. At the same time, the elastic spring, gear and threaded column mechanism are used to realize the automatic extension and retraction of the clamping block without the need for an additional power source. The electric guide rail 728 cooperates with the slide rail 729. When the cardboard body 3 reaches the bottom of the lifting and flipping assembly 7, the drive motor 702 installed on the outer wall of the mounting frame 701 is started. The drive motor 702 drives the transmission screw 703 to rotate, and the lifting rod 704 threadedly connected to the transmission screw 703 rises in the vertical direction to ensure that the lifting rod 704 is lifted vertically without deviation.

[0022] See also Figure 3 and Figure 4 The conveying assembly 2 includes a conveying frame 201, which is installed on the workbench 1. A mounting bracket 202 is fixedly installed on the top outer wall of the workbench 1, and a conveying motor 203 is fixedly installed on the top of the mounting bracket 202. A rotating shaft 204 is fixedly installed on the output end of the conveying motor 203, and a fixed roller 205 is fixedly installed on the outer side of the rotating shaft 204. A conveying belt 206 is rotatably installed on the outer side of the fixed roller 205. A fixed semicircular block 207 is fixedly installed on the top outer wall of the conveying belt 206, and a rotating column 208 is rotatably installed on the inner side of the fixed semicircular block 207. A torsion spring 209 is arranged on the outer side of the rotating column 208. A push plate 210 is fixedly installed on the outer side of the rotating column 208. The length of the push plate 210 is consistent with the length of the cardboard body 3. There is a gap between the conveying frame 201 and the lifting and flipping assembly 7.

[0023] When in use, first turn on the main power of the equipment, start the conveying motor 203, and the rotating shaft 204 at the output end of the conveying motor 203 drives the fixed roller 205 to rotate, thereby driving the cardboard body 3 on the conveyor belt 206 to run. At this time, the push plate 210 at the top of the conveyor belt 206 remains parallel to the conveyor belt 206 under the action of the torsion spring 209. When the cardboard body 3 is transported to the top of the support seat 5 with the conveyor belt 206, and when the cardboard body 3 contacts the support seat 5 at about three-quarters of the position, the conveyor belt 206 will not generate a conveying force on the cardboard body 3. At this time, the push plate 210 contacts the side of the cardboard body 3 to continue to push the cardboard body 3 When the cardboard body 3 is moved to a certain distance, the cardboard body 3 is completely located above the support seat 5, the conveyor belt 206 is running, and there is a clearance gap between the conveyor frame 201 and the lifting and flipping assembly 7, and the clearance gap allows the push plate 210 to pass through. At this time, the push plate 210 is in contact and squeezed with the frame 712, so that the push plate 210 rotates with the rotating column 208, so that the push plate 210 and the rotating column 208 are in a vertical structure, so that the push plate 210 passes through the gap. When the push plate 210 runs to the bottom of the conveyor belt 206, the push plate 210 is restored to its initial state under the action of the torsion spring 209, and continues to run with the conveyor belt 206.

[0024] See also Figure 6 , Figure 7 , Figure 12 and Figure 13 The lifting and flipping assembly 7 also includes a mounting frame 701 mounted on the outer wall of the top end of the workbench 1, a driving motor 702 is fixedly mounted on the outer side of the mounting frame 701, a transmission screw 703 is fixedly connected to the output end of the driving motor 702, and a lifting rod 704 is threadedly connected to the outer side of the transmission screw 703.

[0025] During use, when the cardboard body 3 reaches directly below the lifting and flipping assembly 7, the drive motor 702 installed on the outer wall of the mounting frame 701 is started. The drive motor 702 drives the transmission lead screw 703 to rotate, and then drives the lifting rod 704 threadedly connected to the transmission lead screw 703 to rise vertically, ensuring that the lifting rod 704 lifts vertically without deviation. At this time, the other end of the lifting rod 704 is also driven to rise vertically while maintaining balance on both sides, causing the frame 712 between the two sets of lifting rods 704 to rise. When the drive motor 702 rotates in reverse, the two sets of lifting rods 704 descend vertically along the transmission lead screw 703.

[0026] Please refer to Figure 6 、 Figure 7 、 Figure 12 and Figure 13 As shown in, the lifting and flipping assembly 7 further includes a protruding block 705. A rotating shaft 706 is rotatably connected to the inner side of the lifting rod 704. A ratchet wheel 707 is fixedly connected to the outer side of the rotating shaft 706. A connecting rod 709 is slidably connected to the inner wall of the workbench 1. One end of the outer wall of the connecting rod 709 is fixedly connected to a first rack 708. A rotating rod 710 is rotatably installed on the inner wall of the mounting frame 701. A fixed column 711 is rotatably installed on the inner side of the rotating rod 710.

[0027] During use, when the lifting rod 704 rises, the protruding block 705 on its inner side also rises simultaneously. At this time, since the first rack 708 has teeth in the middle and no teeth on both sides, when the ratchet wheel 707 moves upward for a certain distance and the middle tooth part of the first rack 708 meshes with the ratchet wheel 707, the drive ratchet wheel 707 drives the rotating shaft 706 to rotate, causing the frame 712 to flip from the vertical state to the horizontal state. During this process, when the protruding block 705 rises to the top, it has a reaction force on the rotating rod 710, and there is a middle gap between the rotating rod 710 and the inner wall of the connecting seat, causing the rotating rod 710 to rotate along with the fixed column 711. At this time, the bottom end of the rotating rod 710 will move a certain distance in the direction of the first rack 708, and then push the connecting rod 709, thereby pushing the bottom of the first rack 708 to slide, so that the first rack 708 is disengaged from the ratchet wheel 707 by a certain distance. At this time, when the lifting rod 704 descends, the ratchet wheel 707 and the first rack 708 cannot mesh, so it will not rotate. When the lifting rod 704 is about to reach the bottom during descent, it will move in the opposite direction, thereby pulling the connecting rod 709 to move and driving the first rack 708 to return to its original state. The connecting rod 709 ensures the stable movement of the first rack 708 and avoids shaking.

[0028] Please refer to Figure 12 and Figure 13 As shown in, the connecting rod 709 is fixedly connected to the rotating rod 710. The first rack 708 has teeth in the middle and no teeth on both sides. The first rack 708 is meshed with the ratchet wheel 707.

[0029] During use, When the lifting rod 704 rises by a certain stroke, the ratchet wheel 707 moves with the lifting rod 704 to the middle tooth of the first rack 708 middle tooth Below the area, since the first rack 708 is fixed, the one-way teeth of the ratchet wheel 707 cut into the tooth pattern of the first rack 708 to form a stable meshing. After meshing, the vertical movement of the lifting rod 704 is completely converted into the rotational movement of the ratchet wheel 707, driving the rotating shaft 706 and the frame 712 to flip synchronously. At this time, the protruding block 705 continues to rise but has not yet contacted the rotating rod 710, and the first rack 708 remains stationary, ensuring a smooth flipping process. When the lifting rod 704 approaches the end of its upward movement, the top slope of the protruding block 705 contacts the top of the rotating rod 710, applying a horizontal component force to the right. Due to the lever action of the rotating rod 710, the bottom end pushes the first rack 708 to slide to the right through the connecting rod 709, causing the middle tooth area of the first rack 708 to completely disengage from the ratchet wheel 707. At this time, the frame 712 has flipped to the horizontal state, and the first clamping block 717 and the second clamping block 722 are in place and clamp the cardboard. When the lifting rod 704 descends, since the first rack 708 has moved to the right and disengaged from the ratchet wheel 707, and the one-way teeth of the ratchet wheel 707 prohibit reverse rotation, the frame 712 remains in the horizontal state unchanged, preventing the cardboard from flipping and misaligning during the cleaning process. When the lifting rod 704 descends to the bottom, the protruding block 705 completely disengages from the rotating rod 710, and the rotating rod 710 swings to the left under its own gravity, driving the first rack 708 to move leftward and reset through the connecting rod 709, and the middle tooth area realigns with the ratchet wheel 707.

[0030] Please refer to Figure 12 and Figure 13 , when the protruding block 705 rises, the first rack 708 contacts the ratchet wheel 707, and when the protruding block 705 descends, the first rack 708 does not contact the ratchet wheel 707.

[0031] In use, the lifting rod 704 is at the lowest position, the frame 712 is in a vertical state, the first rack 708 is disengaged from the ratchet wheel 707, the bottom end of the rotating rod 710 is at the initial position, the driving motor 702 is started, driving the transmission lead screw 703 to rotate forward, and the lifting rod 704 rises uniformly in the vertical direction, simultaneously driving the protruding block 705, the rotating shaft 706 and the frame 712 to rise synchronously. When the lifting rod 704 rises to a certain critical height, the ratchet wheel 707 moves with the lifting rod 704 above the middle tooth area of the first rack 708. Since the first rack 708 is fixed to the connecting rod 709, and the connecting rod 709 is connected to the mounting bracket 701 through the rotating rod 710, at this time the first rack 708 remains horizontally stationary, and the ratchet wheel 707 cuts into the tooth pattern area of the first rack 708 due to the upward movement to form meshing. After the ratchet wheel 707 and the first rack 708 are meshed, the vertical movement of the lifting rod 704 is converted into the rotational movement of the ratchet wheel 707, driving the frame 712 to flip from the vertical state to the horizontal state through the rotating shaft 706. When the lifting rod 704 rises to the top, the protruding block 705 contacts the top end of the rotating rod 710. Since the top of the protruding block 705 is a slope, a lateral thrust to the right is exerted on the rotating rod 710, and the rotating rod 710 swings to the right with the fixed column 711 as the fulcrum. Its bottom end drives the first rack 708 to slide to the right through the connecting rod 709, so that the middle tooth area of the first rack 708 is disengaged from the ratchet wheel 707. At this time, the frame 712 has been flipped to the horizontal state, completing the switching of the cardboard clamping position. After the frame 712 is flipped in place and the cardboard is clamped, the driving motor 702 rotates in reverse, the transmission lead screw 703 rotates in the reverse direction, and the lifting rod 704 starts to descend vertically. Since the first rack 708 has moved to the right and disengaged from the ratchet wheel 707, and the ratchet wheel 707 is a one-way tooth structure, the ratchet wheel 707 cannot be meshed with the first rack 708 during the descending process, preventing the frame 712 from flipping in the reverse direction due to the descent of the lifting rod 704. When the lifting rod 704 descends close to the bottom, the protruding block 705 completely disengages from the rotating rod 710, and the rotating rod 710 swings to the left under its own gravity or the action of the return spring. The bottom end of the rotating rod 710 pulls the first rack 708 to slide to the left through the connecting rod 709, returning to the initial position, and the middle tooth area of the first rack 708 is realigned with the ratchet wheel 707, preparing for the meshing during the next upward movement.

[0032] Please refer to Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 and Figure 11The lifting and flipping assembly 7 also includes a frame 712, an upper rack groove 713 is provided on the top outer wall of the frame 712, a lower rack groove 714 is provided on the bottom outer wall of the frame 712, a threaded column 716 is rotatably mounted on the inner wall of the frame 712, a gear 715 is fixedly connected to the outer wall of one end of the threaded column 716, a clamping block 717 is threadedly connected to the outer side of the threaded column 716, an elastic spring 718 is provided on the inner wall of the frame 712, and an elastic spring 718 is provided on the inner wall of the frame 712. A rack 2 719 adapted to the gear 1 715 is provided on the outer wall of one end of the spring 1 718, a threaded column 2 721 is rotatably installed on the inner wall of the frame 712, a gear 2 720 is fixedly connected to the outer wall of one end of the threaded column 2 721, a clamping block 2 722 is threadedly connected to the outer side of the threaded column 2 721, an elastic spring 2 723 is provided on the inner wall of the frame 712, and a rack 3 724 adapted to the gear 2 720 is provided on the outer wall of one end of the elastic spring 2 723.

[0033] When in use, when the frame 712 is turned over on the way up, the elastic spring 2 723 inside the frame 712 is released from the compressed state due to the change in the posture of the frame 712, and the rack 3 724 is pushed to move. When the frame 712 is turned over to the horizontal state, the elastic spring 1 718 and the elastic spring 2 723 inside the frame 712 are released from the compressed state due to the change in the posture of the frame 712, and move toward the middle of the frame 712. The rack 2 719 is meshed with the gear 2 720, driving the gear 2 720 to rotate, and then driving the clamping block 2 722 to extend inwardly through the threaded column 2 721. At the same time, the rack 3 724 is meshed with the gear 1 715, driving the gear 1 715 to rotate, and driving the clamping block 1 717 to extend inwardly through the threaded column 1 716. The two groups of clamping blocks are respectively embedded in both sides of the cardboard body 3 to form a stable clamping force to ensure that the cardboard is cleaned. There is no displacement during the process. When the frame 712 is turned over, its internal structure is also turned over, and the operation mode is also turned over, so that the positions of the clamping block 2 722 and the clamping block 1 717 are reversed. At this time, the clamping block 2 722 and the clamping block 1 717 are gradually withdrawn from the two sides of the cardboard body 3 through the reverse rotation of the threaded column 2 721 and the threaded column 1 716 respectively. At the same time, the elastic spring 1 718 and the elastic spring 2 723 inside the frame 712 are in a compressed state again due to the change of the posture of the frame 712, preparing for the next clamping action. When the frame 712 is completely turned back to the initial position, the entire clamping mechanism returns to the initial state, waiting for the next cardboard clamping and cleaning operation, ensuring the stability and cleaning effect of the cardboard during the processing, and improving the production efficiency and product quality of carton processing.

[0034] See also Figure 9 , Figure 10 and Figure 11, the sizes of gear 1 (715), screw post 1 (716), clamping block 1 (717), elastic spring 1 (718) and rack 2 (719) are the same as those of gear 2 (720), screw post 2 (721), clamping block 2 (722), elastic spring 2 (723) and rack 3 (724).

[0035] During use, when the frame 712 is vertical, both elastic spring 1 (718) and elastic spring 2 (723) are compressed to store elastic potential energy. When the frame 712 starts to tilt, elastic spring 2 (723) releases its potential energy first because the force on the left side decreases, pushing rack 3 (724) to move towards the middle along the lower rack groove 714 and initially engaging with gear 1 (715). When the frame 712 is completely horizontal, elastic spring 1 (718) and elastic spring 2 (723) completely release their potential energy. Rack 2 (719) and rack 3 (724) move to the middle of the frame 712 respectively and fully engage with gear 2 (720) and gear 1 (715), driving the clamping blocks to extend. The frame 712 descends with the lifting rod 704 and starts to reverse flip. Elastic spring 1 (718) and elastic spring 2 (723) are gradually compressed due to gravity, pushing rack 2 (719) and rack 3 (724) to move towards both ends of the frame 712 and disengage from the gears. The friction between the clamping blocks and the cardboard drives screw post 1 (716) and screw post 2 (721) to rotate in the reverse direction, and the clamping blocks quickly retract. At this time, the spring compression potential energy is converted into the rotational kinetic energy of the screw posts, realizing power-free reset. There are limit bosses on the inner wall of the frame 712. When the clamping blocks retract to the initial position, they contact the bosses and stop, avoiding interfering with the subsequent conveying process. The compression amounts of the springs on both sides are monitored in real time by displacement sensors, prompting maintenance personnel to adjust the spring pre-tightening force.

[0036] Please refer to Figure 9 , Figure 10 and Figure 11 , rack 2 (719) and gear 2 (720) are meshed with rack 3 (724) and gear 1 (715). Gear 1 (715), elastic spring 2 (723) and rack 3 (724) are misaligned with gear 2 (720), elastic spring 1 (718) and rack 2 (719).

[0037] During use, the first elastic spring 718 and the second elastic spring 723 are compressed. The second rack 719 and the third rack 724 are respectively located at the upper and lower ends of the frame 712 and are disengaged from the gears. The first clamping block 717 and the second clamping block 722 retract to the inner wall of the frame 712. The frame 712 rises with the lifting rod 704 and begins to flip. The left compression state of the second elastic spring 723 is released due to the inclination of the frame 712, pushing the third rack 724 to move towards the middle of the frame 712 along the lower rack groove 714. When the frame 712 flips to the horizontal state, the first elastic spring 718 and the second elastic spring 723 are completely released from compression and release potential energy towards the middle of the frame 712 at the same time. Driven by the first elastic spring 718, the second rack 719 moves towards the middle along the upper rack groove 713 and meshes with the second gear 720, driving the second threaded column 721 to rotate clockwise, driving the second clamping block 722 to extend towards the inside. Driven by the second elastic spring 723, the third rack 724 moves towards the middle along the lower rack groove 714 and meshes with the first gear 715, driving the first threaded column 716 to rotate counterclockwise, driving the first clamping block 717 to extend towards the inside. The two groups of clamping blocks are simultaneously embedded into the two side edges of the cardboard body 3, forming a symmetrical clamping force to ensure that there is no lateral displacement of the cardboard during the cleaning process. After the upper surface of the cardboard is cleaned by the frame 712, it begins to descend and flip. The first elastic spring 718 and the second elastic spring 723 re-enter the compressed state due to the inclination of the frame 712. The second rack 719 and the third rack 724 are pushed back to both ends of the frame 712 by the springs and are disengaged from the gears. The first threaded column 716 and the second threaded column 721 rotate in the reverse direction under the frictional force of the clamping blocks, driving the clamping blocks to retract towards the outside. When the frame 712 returns to the vertical position, the first clamping block 717 and the second clamping block 722 are completely retracted to the inner wall of the frame 712, and the compression amount of the spring returns to the initial value, waiting for the next clamping instruction.

[0038] Please refer to Figure 1 and Figure 8 As shown in FIGS. and, the electric guide rail 728 is slidably connected to the sliding seat 730, and the vertical section of the filter scraper 734 is in an L-shaped structure.

[0039] In use, after the cardboard is fixed, the electric cylinder 725 is activated. The telescopic rod 726 drives the cleaning top plate 727 to move downward. The notch at one end of the cleaning top plate 727 avoids the driving motor 702 to prevent interference. When the cleaning head 733 contacts the upper surface of the cardboard body 3, the driving power supply supplies power to the electric guide rail 728 and the cleaning machine body 731. The electric guide rail 728 pushes the sliding seat 730 to move horizontally along the slide rail 729, so that the cleaning head 733 reciprocates on the cardboard surface. The L-shaped filtering scraper 734 outside the cleaning head 733 closely adheres to the cardboard surface and scrapes and collects dust and impurities when moving with the cleaning head 733 to prevent secondary pollution. After the upper surface cleaning is completed, the electric cylinder 725 drives the cleaning top plate 727 to reset. The driving motor 702 rotates reversely, the lifting rod 704 descends, the first rack 708 disengages from the ratchet wheel 707, and the frame 712 flips 180°, making the lower surface of the cardboard body 3 face upward. Repeat the steps of the cleaning top plate 727 descending and the cleaning head 733 moving to complete the cleaning of the lower surface of the cardboard.
