Description

Technical Field

[0001] This invention relates to the field of cardboard production technology, specifically to cardboard slotting and paper scrap processing equipment. Background Technology

[0002] Die-cutting machines are mainly used for die-cutting (full cut, half cut), creasing and hot stamping of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic and mobile phone pads, etc., as well as lamination and automatic waste removal. Die-cutting machines use steel knives, hardware molds, and steel wire (or templates carved from steel plates) to apply a certain pressure through the printing plate to cut printed materials or cardboard into a certain shape. They are important equipment for post-printing packaging processing.

[0003] After the die-cutting machine slots the cardboard, it discharges the cardboard from the unloading port onto the conveyor, where it continues to be transported via a belt conveyor. During unloading onto the conveyor, paper scraps fall off. However, because these scraps can get stuck at the cut edges, they are transported along with the cardboard, resulting in paper scraps covering the entire conveying area. Furthermore, these scraps are easily transported to the next processing station, polluting the environment and increasing process costs. Therefore, we propose a cardboard slotting paper scrap handling equipment to address this existing technological deficiency. Summary of the Invention

[0032] Furthermore, the right side of the guide limiting plate is configured with a Y-shaped opening, and a telescopic rod is provided between the guide limiting plate and the conveyor base.

[0033] Compared with the prior art, the present invention provides a cardboard slotting and paper scrap treatment device, which has the following beneficial effects:

[0034] 1. This cardboard slotting and scrap treatment equipment involves setting up a conveyor base on the ground, with the right end of the conveyor base positioned below the unloading port of the die-cutting machine. Adjusting the adjustment components on the support base according to the width of the cardboard ensures the width between the guide limit plates equals the width of the cardboard. Adjusting the displacement components according to the thickness of the cardboard moves the tripod horizontally and vertically, causing the inclined surfaces of the tripod to contact the inner surfaces of the two guide limit plates, and ensuring the distance between the blocking brush and the conveyor belt equals the thickness of the cardboard. Furthermore, based on the fixed die-cutting slotting position on the cardboard, multiple air pipes are moved outwards from the guide rods on the support frame, ensuring each air pipe is positioned above the die-cutting slotting position. After adjustment, the pipes are locked in place by locking components.

[0035] After adjustment, the die-cut cardboard falls onto the conveyor belt through the discharge port. The conveyor rollers rotate, driving the conveyor belt to transport the cardboard. The width of the cardboard is limited by the guide limit plate. During the transport process, the paper scraps generated by die-cutting fall into the receiving hopper through the through-hole. During the transport of the die-cut cardboard, high-pressure air is supplied into the air pipes through the high-pressure air blown out by the high-pressure air blown head on the air pipes. The high-pressure air blown head on each air pipe blows high-pressure air at the die-cutting position of the carton, blowing the paper scraps stuck in the die-cutting hole into the receiving hopper. In addition, during the transport of the die-cut cardboard, some paper scraps scattered on the surface of the die-cut cardboard are blocked by the blocking brush, preventing them from being transported with the die-cut cardboard. The blocked paper scraps fall into the receiving hopper through the through-hole, thus achieving thorough cleaning and collection of the paper scraps generated by die-cutting cardboard, preventing them from being scattered throughout the transport area and transported to the next station with the cardboard, increasing process costs and polluting the environment.

[0036] 2. This cardboard slotting paper scraps processing equipment works by having the cleaned paper scraps fall into the receiving hopper, where a crushing mechanism crushes the scraps. The crushed scraps then fall into the collecting hopper, where a switch plate and a push plate seal the opening. An extrusion assembly then compresses the collected crushed paper scraps. After compression, a vertical pusher opens one side of the opening, and a horizontal pusher moves the push plate laterally to push the extruded rectangular blocks of paper scraps out of the collecting hopper, facilitating centralized processing and reuse of the paper scraps generated during cleaning.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1 to 4The cardboard slotting and paper scrap handling equipment includes a conveyor base 1, which is made of high-strength steel and has good stability and load-bearing capacity. The bottom of the conveyor base 1 is bolted with a support frame for stable placement of the entire equipment. The right end of the conveyor base 1 is located below the discharge port of the die-cutting machine. The left and right sides of the upper end of the conveyor base 1 are provided with through-holes 2, which are rectangular openings for paper scraps to fall. The inner walls of the left and right sides of the conveyor base 1 are connected to rotating conveyor rollers 3, which are connected to the conveyor base 1 through bearings. The conveyor rollers 3 are driven to rotate by a drive motor and are located above the through-holes 2. Multiple conveyor belts 4 are driven between the outer sides of the conveyor rollers 3. The number of conveyor belts 4 can be 5-10, which pass through the conveyor base 1. The conveyor belts 4 are made of rubber and have a certain degree of flexibility and wear resistance for conveying cardboard.

[0048] The equipment also includes a pair of adjusting support seats 5, which are bolted to the front and rear sides of the upper right surface of the conveyor base 1. The adjusting support seats 5 are equipped with adjusting components for adjusting the movement of the guide limit plate 31. The adjusting components include an adjusting hole 6, a connecting rod 7, an adjusting screw 8, and an adjusting nut 9. The adjusting hole 6 is an elongated hole on the adjusting support seat 5 to facilitate the movement of the connecting rod 7 and the adjusting screw 8. The connecting rod 7 is bolted to the upper surface of the guide limit plate 31 and passes through the adjusting support seat 5. The guide limit plate 31 is located above the through-hole 2. The adjusting screw 8 is vertically fixed to the upper surface of the connecting rod 7 and passes through the adjusting hole 6. The adjusting nut 9 is threaded onto the outside of the adjusting screw 8 and fits against the upper surface of the adjusting support seat 5. A scale 10 is bolted to the right side surface of the adjusting support seat 5. The scale 10 has gradually increasing markings from the inside to the outside. A pointer 1 is fixed to the right side surface of the connecting rod 7. 1. The pointer 11 and the connecting rod 7 are aligned with the surface of the end away from the adjusting support 5. The pointer 11 is in contact with the surface of the scale 10. When adjusting the distance between the guide limit plates 31, the connecting rod 7 and the adjusting screw 8 are moved in the adjusting hole 6 by adjusting the guide limit plates 31. When the connecting rod 7 moves, the pointer 11 moves synchronously, so that the pointer 11 indicates the scale on the scale 10, thereby achieving the purpose of accurately adjusting the moving distance of the guide limit plates 31, so that the distance between the guide limit plates 31 is equal to the width of the cardboard. After adjustment, the adjustment can be fixed by tightening the adjusting nut 9. The guide limit plates 31 are in contact with the conveyor belt 4. The right side of the combination is set with a Y-shaped opening, which facilitates the smooth entry of the cardboard into the guide limit plates 31. A telescopic rod 2 30 is provided between the guide limit plates 31 and the conveyor base 1. The telescopic rod 2 30 provides telescopic support for the guide limit plates 31, ensuring the stability of the movement adjustment of the guide limit plates 31.

[0049] The equipment also includes a pair of support frames 12, which are also bolted to the front and rear sides of the upper right surface of the conveyor base 1 and located on the left side of the adjusting support base 5. Multiple guide rods 13 are welded between the support frames 12. In this application, there is a pair of guide rods 13. The guide rods 13 are rectangular with smooth surfaces. Multiple air pipes 15 slide between the guide rods 13. The air pipes 15 are connected and locked to the guide rods 13 by locking components. The locking components include a sliding seat 14 fixed to the outside of the air pipes 15 and sliding outside the guide rods 13. A locking nut 16 is welded to the upper surface of the sliding seat 14. The internal threaded connection has a locking screw 17 that passes through the sliding seat 14 and contacts the guide rod 13. When the air pipe 15 is adjusted to align with the die-cutting slot position, the movement of the air pipe 15 drives the sliding seat 14 to move synchronously and directionally outside the guide rod 13. After the air pipe 15 is adjusted, the locking screw 17 is tightened in the internal thread of the locking nut 16 to fix the air pipe 15 after adjustment. Multiple high-pressure air blowers 18 are connected to the air pipe 15. The exhaust ports of the high-pressure air blowers 18 are vertically downward, and the number can be 8-10. The high-pressure air blowers 18 are evenly distributed on the air pipe 15 and are used to blow out high-pressure airflow to clean paper scraps.

[0050] The high-pressure air supply assembly is located on the conveyor base 1 and is used to discharge high-pressure airflow into the air pipe 15. The high-pressure air supply assembly includes a booster fan 21, a connecting air pipe 22, a straight pipe 19, and a hose 20. The booster fan 21 is fixed to the front surface of the conveyor base 1 by bolts. It adopts a high-efficiency centrifugal fan and can provide a stable high-pressure airflow. The straight pipe 19 is fixed to the upper surface of the support frame 12 by bolts. The connecting air pipe 22 is connected to the exhaust port of the booster fan 21. The other end of the connecting air pipe 22 is connected to the straight pipe 19. The hose 20 is connected between the straight pipe 19 and the air pipe 15. When the booster fan 21 works, it discharges high-pressure airflow. By utilizing the interconnection between the booster fan 21, the connecting air pipe 22, the hose 20, the straight pipe 19, and the high-pressure blowing head 18, the high-pressure airflow is ejected through the high-pressure blowing head 18.

[0051] The displacement assembly is mounted on the conveyor base 1, located on the left side of the support frame 12. It drives the tripod 26 to move laterally and vertically, causing the inclined surfaces of the tripod 26 to respectively conform to the inner surfaces of the two guide limit plates 31. A blocking brush 27, made of nylon bristles, is fixed to the bottom of the tripod 26. The displacement assembly includes an electric push rod 23, a moving frame 24, at least one pair of telescopic rods 25, a moving screw 28, and a limiting nut 29. The electric push rod 23 is bolted to the upper surface of the conveyor base 1. The moving frame 24 is fixed to the push rod of the electric push rod 23. The telescopic rods 25 are vertically fixed to the lower surface of the moving frame 24. In this application, there is one pair of telescopic rods 25, symmetrically distributed front and back. The other end of each telescopic rod 25 is connected and fixed to the tripod 26. The moving screw 28 is fixed to the upper surface of the tripod 26. The moving screw 28 extends to the top of the moving frame 24, and the limiting nut 29 is threaded onto the outside of the moving screw 28. The limiting nut 29 fits against the upper surface of the moving frame 24. After the spacing between the guide limiting plates 31 is adjusted, the moving frame 24, telescopic rod 25, moving screw 28, limiting nut 29, tripod 26, and blocking brush 27 are moved synchronously by the electric push rod 23. This allows the inclined surface of the tripod 26 to fit against the inner surfaces of the two guide limiting plates 31, ensuring that the blocking brush 27 can block paper scraps from the cardboard between the guide limiting plates 31 in all directions. By adjusting the limiting nut 29, the moving screw 28 drives the tripod 26 to move up and down for adjustment. The telescopic rod 25 simultaneously extends and retracts to support the movement, thus changing the distance between the blocking brush 27 on the tripod 26 and the conveyor belt 4 to be equal to the thickness of the cardboard.

[0052] Please see Figures 5 to 8 The receiving hopper 32 is bolted to the bottom of the conveyor base 1, located below the right-side opening 2, and is used to receive falling paper scraps. A crushing mechanism is located inside the receiving hopper 32 to crush the falling paper scraps. The crushing mechanism includes a pair of guide plates 33, a pair of crushing motors 34, and a pair of crushing rollers 35. The guide plates 33 are sealed and fixed to the inner wall of the receiving hopper 32. The guide plates 33 are inclined downwards and have gaps between them to facilitate the introduction of paper scraps. The pair of crushing motors 34 are bolted to the bottom of the conveyor base 1. The crushing roller 35 is installed and fixed on the right surface of the receiving hopper 32. It is connected and fixed to the output end of the crushing motor 34. The other end of the crushing roller 35 is connected to the inner wall of the receiving hopper 32 and rotates. The crushing roller 35 is attached to the lower surface of the guide plate 33 and is located below the gap between the guide plates 33. The paper scraps falling into the receiving hopper 32 are guided to the gap between the guide plates 33 by the inclined surface of the guide plates 33, and the crushing roller 35 is driven to rotate by the crushing motor 34 to achieve the tearing and crushing of the paper scraps and discharge through the receiving hopper 32.

[0053] The collecting hopper 36 is bolted to the bottom of the conveyor base 1 and is located below the discharge port of the receiving hopper 32. The left and right sides of the collecting hopper 36 are open, and a switch plate 38 and a push plate 40 are respectively sealed and slidably installed in the openings on both sides. The switch plate 38 and the push plate 40 are both in contact with the front and rear side walls and bottom wall of the inner cavity of the collecting hopper 36. The vertical pushing component 37 is bolted to the bottom of the conveyor base 1, and the horizontal pushing component 39 is bolted to the bottom of the collecting hopper 36. The horizontal pushing component 39 pushes the push plate 40 to move horizontally, and the vertical pushing component 37 pushes the switch plate 38 to move vertically. The vertical pushing component 37 is a hydraulic push rod one, and the horizontal pushing component 39 is a hydraulic push rod two. The hydraulic push rod one is located at the bottom of the conveyor base 1, and the push rod of the hydraulic push rod one is connected and fixed to the switch plate 38. The hydraulic push rod two is located at the lower left side of the collecting hopper 36, and the push rod of the hydraulic push rod two is connected and fixed to the push plate 40.

[0054] An extrusion assembly is located above the opening of the collecting hopper 36 and is used to extrude and shape the shredded paper scraps. The extrusion assembly includes a hydraulic cylinder 41 that is bolted to the upper surface of the collecting hopper 36. An extrusion plate 42 is fixed to the push rod of the hydraulic cylinder 41. The collecting hopper 36 has a rectangular cavity. The extrusion plate 42 is the same length and width as the rectangular cavity. When the push rod of the hydraulic cylinder 41 is in the fully retracted state, the extrusion plate 42 is located above the rectangular cavity. The extrusion plate 42 is triangular, with a flat bottom and a downward sloping upper surface, with the middle and rear sides being inclined surfaces. After the shredded paper scraps fall into the rectangular cavity in the collecting hopper 36, the switch plate 38 and the push plate 40 are moved by hydraulic push rod one and hydraulic push rod two, so that the collecting hopper 36 can be extruded and shaped at the opening. After sealing, the hydraulic cylinder 41 pushes the extrusion plate 42 downward to compress the crushed material in the rectangular cavity into rectangular blocks. After extrusion molding, the extrusion plate 42 moves upward a certain distance while maintaining the isolation and sealing of the rectangular cavity. This allows the hydraulic push rod 1 to drive the switch plate 38 downward to open one side opening, and the hydraulic push rod 2 to push the push plate 40 to move, pushing the formed rectangular block material out of the opening. This achieves centralized processing and reuse of paper scraps. After pushing out, the switch plate 38 and push plate 40 move back to their original positions to seal the opening of the collection hopper 36, and move the extrusion plate 42 to the top of the rectangular cavity. This allows the crushed paper scraps scattered on the upper surface of the extrusion plate 42 to fall along the slope into the collection hopper 36 for further storage and extrusion molding.

[0055] This equipment is equipped with a control system, which uses a programmable logic controller (PLC) to automatically control each component through preset programs.

[0056] Usage steps:

[0057] Adjust the adjusting components according to the width of the cardboard so that the width between the two guide limit plates 31 is equal to the width of the cardboard. By observing the position of the pointer 11 on the scale 10, precisely adjust the spacing of the guide limit plates 31. After adjustment, tighten the adjusting nut 9.

[0058] According to the thickness of the cardboard, adjust the displacement component so that the inclined surface of the tripod 26 is respectively attached to the inner surface of the two guide limit plates 31, and make the distance between the blocking brush 27 and the conveyor belt 4 equal to the thickness of the cardboard. By adjusting the limit nut 29, the moving screw 28 drives the tripod 26 to move up and down for adjustment, and the telescopic rod 25 simultaneously extends and retracts for support.

[0059] According to the fixed die-cutting slot position on the cardboard, adjust the multiple air pipes 15 to move outward from the guide rod 13 on the support frame 12 so that each air pipe 15 is located above the die-cutting slot position. After the adjustment is completed, tighten the locking screw 17 into the locking nut 16 to fix the position of the air pipe 15.

[0060] Start the equipment. The cardboard die-cut by the die-cutting machine falls onto the conveyor belt 4 through the unloading port. The conveyor roller 3 rotates to drive the conveyor belt 4 to transport the cardboard. The guide limit plate 31 limits the width of the cardboard during transport.

[0061] During the conveying process, the high-pressure air supply component discharges high-pressure airflow into the air pipe 15 and blows it out through the high-pressure air blower 18, blowing the paper scraps stuck in the die-cutting hole into the receiving hopper 32. At the same time, the blocking brush 27 blocks the paper scraps on the upper surface of the cardboard, causing the paper scraps to fall into the receiving hopper 32.

[0062] The paper scraps falling into the receiving hopper 32 are crushed by the crushing mechanism, and the crushed paper scraps fall into the collecting hopper 36.

[0063] When the amount of paper scraps in the collection hopper 36 reaches a certain level, the vertical pusher 37 and the horizontal pusher 39 are activated to close the opening of the collection hopper 36, and the extrusion assembly extrudes and compresses the collected shredded paper.

[0064] After extrusion, the vertical pusher 37 drives the switch plate 38 to open one side opening, and the horizontal pusher 39 pushes the pusher plate 40 to move laterally, pushing the extruded rectangular paper scraps out of the collection hopper 36, realizing the centralized processing and reuse of paper scraps.

[0065] After the ejection is completed, the switch plate 38 and push plate 40 move and reset to open and seal the collection hopper 36. The extrusion plate 42 moves to the top of the rectangular cavity, and the shredded paper scraps scattered on the upper surface of the extrusion plate 42 fall into the collection hopper 36 along the inclined plane for storage and extrusion molding again.

[0066] Beneficial effects:

[0067] By thoroughly cleaning and collecting paper scraps, the high-pressure airflow blown out by the high-pressure air head 18 cleans up the paper scraps stuck in the die-cutting orifice, and the blocking brush 27 blocks the paper scraps scattered on the surface of the cardboard. This achieves thorough cleaning and collection of paper scraps generated by die-cutting cardboard, preventing paper scraps from scattering throughout the entire conveying area and being transported synchronously with the cardboard to the next station, thus reducing process costs and environmental pollution.

[0068] For convenient centralized processing and reuse, the cleaned paper scraps fall into the receiving hopper 32, are crushed by the crushing mechanism, and then fall into the collecting hopper 36 for extrusion and molding. Finally, the molded rectangular paper scraps are pushed out of the collecting hopper 36, which facilitates the centralized processing and reuse of the paper scraps generated during cleaning and improves the resource utilization rate.

[0069] Precise adjustment and stable operation: The adjustment component can precisely adjust the distance between the guide limit plates 31 to make it equal to the width of the cardboard. The displacement component can adjust the distance between the blocking brush 27 and the conveyor belt 4 according to the thickness of the cardboard, ensuring that the equipment can adapt to cardboard of different specifications. At the same time, the connection between each component is firm and the operation is stable, which can guarantee the long-term reliable operation of the equipment.

[0070] Automated control improves the automation level and production efficiency of equipment, and reduces the workload of manual operation.

[0071] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
