Description

Technical Field

[0001] This invention belongs to the field of cardboard box processing technology, and particularly relates to a waste removal machine for cardboard box processing and its usage method. Background Technology

[0002] Cardboard box processing is a core technology in the packaging industry. Using corrugated cardboard as the main raw material, it is the most widely used paper packaging product production process. It uses kraft paper, linerboard, and corrugated core paper as base materials, and goes through processes such as corrugation forming, lamination, paper cutting and creasing, printing, slotting, die cutting, and stapling or gluing to produce cardboard boxes of different specifications such as three-layer, five-layer, and seven-layer. Waste removal machines are post-printing processing equipment specifically for the printing and packaging industry. Their core purpose is to remove waste materials from die-cut products such as cardboard boxes, paper boxes, and labels.

[0003] Traditional waste removal machines mostly use a flat workbench structure. After the waste removal is completed, the cut waste edges and paper scraps will directly accumulate on the workbench. At this time, the staff needs to stop the equipment production and manually use tools to scrape and pick up the waste. The whole cleaning process is time-consuming and labor-intensive, which greatly increases the labor intensity of the operators and thus restricts the overall production efficiency. In order to solve the above problems, there is an urgent need for a waste removal machine for cardboard box processing and its usage method. Summary of the Invention

[0019] The fixing rod is rotatably connected to the base wall via a bearing, the side plate is in close contact with the outer wall of the base, the push groove is designed vertically, and the fixing block slides within the arc groove and the push groove.

[0020] As a further description of the above technical solution:

[0021] A rubber sleeve is fitted onto the top pin. A top head is fixedly connected to one end of the top pin, and a connector is fixedly connected to the other end of the top pin. A magnetic block is fixedly connected to the connector. The top head and the connector are both inserted into the rubber sleeve. The position of the connector hole corresponds to that of the through hole. The connector is inserted into the connector hole. The top pin slides through the through hole. The magnetic block is magnetically attracted to the main movable table and the auxiliary movable table.

[0022] A method of using a waste removal machine for cardboard box processing, the method comprising the following steps:

[0023] Before cleaning up the waste, the main hydraulic push rod and the auxiliary hydraulic push rod are activated to move the main moving table and the auxiliary moving table respectively, so that the main moving table and the auxiliary moving table move closer to the worktable. At this time, the workers remove the rubber sleeves that are fitted on the plugs and put the removed rubber sleeves on the top material head at one end of the top material pin. Then, the plugs of multiple top material pins are inserted into the plug holes on the main moving table and fixed by the magnetic attraction of the magnetic blocks and the magnetic attraction of the main moving table, so that the position of the top material pins on the main moving table corresponds to the waste edge of the core material of the finished carton.

[0024] Next, insert the connectors of multiple top pins through the through holes on the placement plate into the connector holes on the secondary movable table. Simultaneously, use the magnetic attraction blocks to fix them with the magnetic attraction of the secondary movable table, so that the position of the top pins on the secondary movable table corresponds to the core material of the finished carton. After completion, start the main hydraulic push rod and the secondary hydraulic push rod to pull the main movable table and the secondary movable table to reset respectively, and stack the die-cut cardboard on the placement plate. Then, start the electric push rod in the positioning components on both sides above the base to make the electric push rod push the movable plate to move.

[0025] During the process, the movable plate synchronously drives the connecting strip to move, causing the movable pin at one end of the connecting strip to slide in the inclined groove. Then, the movable pin is pushed by the groove wall of the inclined groove, causing the movable pin to drive the movable plate through the connecting strip. The movable plate moves horizontally on the connecting block through the connecting groove, so that the movable plate slides vertically while being pushed horizontally by the electric push rod. Finally, through two L-shaped movable plates that are close to each other, the vertical and horizontal edges of the movable plates are respectively attached to the side and bottom edges of the cardboard to form a positioning structure.

[0026] Then, the main hydraulic push rod and the auxiliary hydraulic push rod are activated simultaneously. The main hydraulic push rod pushes the main movable table down, causing the pressure plate to contact the cardboard. When the top pin on the main movable table passes through the through hole on the pressure plate and contacts the waste edge, the main movable table is stopped from being pushed down. Meanwhile, the auxiliary hydraulic push rod pushes the auxiliary movable table up, causing the top pin on the auxiliary movable table to pass through the through hole on the placement plate and contact the finished core material. At this time, the auxiliary movable table is pushed up, causing the top pin to push out the finished core material, so that the finished core material is separated from the waste edge.

[0027] During the process, the top pin pushes the pressure plate upward through the finished core material, causing the connecting rod to slide on the main movable table and stretch the connecting spring. Then, the rebound of the connecting spring makes the pressure plate press against the finished core material. Finally, the main hydraulic push rod is activated to move the pressure plate away from the finished core material. At this time, the worker takes out the finished core material and then activates the auxiliary hydraulic push rod to pull the auxiliary movable table to move the top pin away from the worktable. Then, the electric push rod pulls the movable plate away from the worktable and embeds it into the base wall.

[0028] Then, start the drive motor to rotate the threaded rod. The threaded sleeve and the threaded rod are used to drive the movable frame to slide along the guide rod and the limiting groove. During the process, the fixed block on the connecting frame will be pushed by the push groove on the side plate of the movable frame, which will cause the connecting frame to drive the worktable to rotate around the fixed rod. During the process, the fixed block slides along the arc groove, which will cause the worktable to tilt and cause the waste edge left on the worktable to be discharged from the discharge port on both sides of the base.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, the drive motor is started to drive the threaded rod to rotate. The threaded sleeve and the threaded rod are engaged to allow the movable frame to slide along the guide rod and the limiting groove. During the process, the push grooves on the side plates of the movable frame can push the fixed block on the connecting frame, causing the connecting frame to drive the worktable to rotate around the fixed rod inside the base. During the process, the fixed block can slide along the arc groove, thereby causing the worktable to gradually tilt. This causes the waste edge left on the worktable to be discharged from the discharge port on both sides of the base. There is no need for workers to manually pick up and move the waste edge, thus completing the cleaning of the worktable and greatly reducing the cost of manual intervention and the intensity of work. 2. In this invention, the movable plate is moved by the electric push rod in the positioning component. During the process, the movable plate can drive the connecting strip to move synchronously, so that the movable pin at one end of the connecting strip slides in the inclined groove. Then, the movable pin is pushed by the groove wall of the inclined groove, so that the movable pin pushes the movable plate through the connecting strip. The movable plate moves horizontally on the connecting block through the connecting groove, so that the movable plate can slide vertically along the direction of the connecting groove while being pushed horizontally by the electric push rod. Finally, through two L-shaped movable plates that are close to each other, the vertical and horizontal sides of the two movable plates are respectively attached to the side and bottom edge of the cardboard to form a positioning structure, which prevents the cardboard from shifting and sliding during waste removal. 3. In this invention, by removing the rubber sleeve from the connector and attaching it to the top material head at one end of the top material pin, the worker can insert the connector into the insertion holes on the main and auxiliary movable platforms. This causes the magnetic block on the top material pin connector to magnetically attract the main and auxiliary movable platforms, thereby completing the arrangement and fixing of the top material pin. Furthermore, the position of the top material pin can be flexibly arranged through the multiple insertion holes on the main and auxiliary movable platforms to adapt to the layout requirements of different specifications of carton core material and waste edge.

Detailed Implementation

[0038] 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.

[0039] In its specific implementation, such as Figures 1-7 This invention provides a technical solution: a waste removal machine for cardboard box processing, comprising a base 1 and positioning components 2. The base 1 has discharge ports 3 on both sides. Two positioning components 2 are fixedly installed on the upper sides of the base 1 in a centrally symmetrical manner. Each positioning component 2 includes an electric push rod 201, with a connecting block 202 fixedly connected to the movable end of the electric push rod 201. A movable plate 203 is slidably connected to the connecting block 202, and a connecting groove 204 is provided on the movable plate 203. The movable plate 203 is L-shaped and fits into the base. Inside the wall above seat 1, a connecting strip 205 is fixedly connected to one side of the movable plate 203. A movable pin 206 is connected to one end of the connecting strip 205. The movable pin 206 slides in the inclined groove 10. Both the connecting block 202 and the connecting groove 204 are T-shaped, and the connecting block 202 and the connecting groove 204 slide together. By the mutual approach between the two centrally symmetrical L-shaped movable plates 203, the vertical and horizontal edges of the two movable plates 203 respectively fit against the two sides and the bottom edge of the die-cut cardboard, forming a positioning and clamping structure to prevent accidental slippage.

[0040] A fixed frame 4 is fixedly connected above the base 1, and a support frame 5 is fixedly connected inside the base 1 below. A worktable 6 is rotatably mounted on the base 1. Limit grooves 7 are opened on both sides of the base 1, and arc-shaped grooves 8 are opened on both sides of the base 1 above the limit grooves 7. Connecting plates 9 are fixedly connected to the upper two sides of the base 1 in a centrally symmetrical manner. An inclined groove 10 is opened on the connecting plate 9, and one end of the inclined groove 10 is designed to extend horizontally. A main mounting frame 11 is fixedly mounted on the fixed frame 4. A main hydraulic push rod 12 is fixedly mounted on the main mounting frame 11. A main movable table 13 is fixedly connected to the movable end of the main hydraulic push rod 12. The four corners of the main movable table 13 are slidably connected to... A connecting rod 14 is fixedly connected to a pressure plate 15 at one end. A connecting spring 35 is sleeved on the connecting rod 14. One end of the connecting spring 35 is fixedly connected to the top of the connecting rod 14, and the other end of the connecting spring 35 is fixedly connected to the upper wall of the main movable table 13. When the top material pin 27 pushes the finished core material and moves the pressure plate 15 upward, the connecting spring 35 will be stretched synchronously and generate a reverse force, so that the pressure plate 15 can adhere to the upper surface of the finished core material to form a pressing effect. The horizontal extension design at one end of the inclined groove 10 can make the movable plate 203 smoothly embedded into the wall of the base 1 or slide out of the wall when the movable plate 203 is pushed and pulled.

[0041] A secondary mounting bracket 16 is fixedly installed on the support frame 5, and a secondary hydraulic push rod 17 is fixedly installed on the secondary mounting bracket 16. Two guide rods 18 are fixedly connected to one side of the support frame 5, and a drive motor 19 is fixedly installed on the other side of the support frame 5. The output shaft of the drive motor 19 is connected to a threaded rod 20, and a movable frame 21 is slidably installed through the threaded rod 20. The movable frame 21 slides in the limiting groove 7, and a connecting hole 33 is opened on the side of the movable frame 21 away from the threaded sleeve 22. The guide rod 18 slides through the connecting hole 33 and is slidably engaged with the movable frame 21. The end of the guide rod 18 away from the support frame 5 is fixedly connected to the inner wall of the base 1. When the movable frame 21 moves, the movable frame 21 can slide synchronously in the guide rod 18 and the limiting groove 7, thereby supporting and guiding the movable frame 21 through the guide rod 18 and the limiting groove 7, and preventing the movable frame 21 from tilting when moving.

[0042] A threaded sleeve 22 is fixedly installed inside one side wall of the movable frame 21. The threaded rod 20 is rotatably connected to the inner wall of the support frame 5 and the base 1 through bearings. The threaded rod 20 and the threaded sleeve 22 are threadedly engaged. Two corrugated telescopic covers 34 are sleeved on the threaded rod 20. The two corrugated telescopic covers 34 are located at both ends of the threaded rod 20, and one end of each of the two corrugated telescopic covers 34 is fixedly connected to the wall of the movable frame 21. The other end of each of the two corrugated telescopic covers 34 is fixedly connected to the inner wall of the support frame 5 and the base 1, respectively. When the threaded rod 20 drives the movable frame 21 to move, the movable frame 21 can compress and stretch the corrugated telescopic covers 34 on both sides respectively, so that the corrugated telescopic covers 34 can cover and protect the threaded rod 20 when the movable frame 21 moves, effectively preventing debris, dust and other impurities from adhering to the threaded rod 20.

[0043] Side plates 23 are fixedly connected to both sides of the upper part of the movable frame 21. Push grooves 24 are opened on the side plates 23. The movable end of the auxiliary hydraulic push rod 17 is fixedly connected to the auxiliary movable platform 25. The auxiliary movable platform 25 and the main movable platform 13 are both provided with multiple insertion holes 26. The main movable platform 13 and the auxiliary movable platform 25 are both installed with top material pins 27 through the insertion holes 26. A rubber sleeve 36 is fitted on the top material pin 27. One end of the top material pin 27 is fixedly connected to the top material head 37. The other end of the top material pin 27 is fixedly connected to the connector 38. A magnetic block 39 is fixedly connected to the connector 38. The top material head 37 and the connector 38 are both connected to the rubber sleeve 39. The rubber sleeve 36 is inserted and fitted, the insertion hole 26 corresponds to the position of the through hole 32, the insertion connector 38 is inserted into the insertion hole 26, the top pin 27 slides through the through hole 32 and is fitted with the through hole 32, and the magnetic block 39 is magnetically attracted to the main movable table 13 and the auxiliary movable table 25. When the rubber sleeve 36 is fitted on the insertion connector 38, it can isolate and protect the magnetic block 39, preventing impurities from adhering to the surface of the magnetic block 39 when idle or not assembled. When the rubber sleeve 36 is fitted on the top head 37, it can be squeezed during the top feeding process, thereby buffering the contact between the top head 37 and the cardboard to avoid indentation and damage.

[0044] A placement plate 28 is fixedly connected to the workbench 6. Connecting frames 29 are fixedly connected to both sides below the workbench 6. A fixing rod 30 is fixedly connected to the connecting frame 29. A fixing block 31 is fixedly connected to the connecting frame 29 above the fixing rod 30. Multiple through holes 32 are opened on the pressure plate 15 and the placement plate 28. The fixing rod 30 is rotatably connected to the wall of the base 1 through a bearing. The side plate 23 is in contact with the outer wall of the base 1. The push groove 24 is designed vertically. The fixing block 31 slides in the arc groove 8 and the push groove 24. The contact between the side plate 23 and the outer wall of the base 1 can provide auxiliary limit for the movement of the movable frame 21, preventing deviation when pushing the fixing block 31. The sliding of the fixing block 31 in the arc groove 8 allows the connecting frame 29 to drive the workbench 6 to rotate smoothly along the trajectory of the arc groove 8 when the push groove 24 pushes the fixing block 31, thereby controlling the tilt of the workbench 6 to complete the material discharge.

[0045] A method for using a waste removal machine for cardboard box processing, comprising the following steps:

[0046] Before cleaning up the waste, the main hydraulic push rod 12 and the auxiliary hydraulic push rod 17 are activated to move the main movable table 13 and the auxiliary movable table 25 respectively, causing the main movable table 13 and the auxiliary movable table 25 to move closer to the worktable 6. At this time, the workers remove the rubber sleeve 36 that is fitted on the plug 38 and put the removed rubber sleeve 36 on the top material head 37 at one end of the top material pin 27. Then, the plugs 38 of multiple top material pins 27 are inserted into the plug holes 26 on the main movable table 13 and fixed by the magnetic attraction of the magnetic block 39 to the main movable table 13, so that the position of the top material pin 27 on the main movable table 13 corresponds to the waste edge of the core material of the finished carton.

[0047] Next, insert the connectors 38 of multiple top pins 27 through the through holes 32 on the placement plate 28 into the insertion holes 26 on the auxiliary movable table 25. Simultaneously, use the magnetic attraction block 39 to fix the auxiliary movable table 25 with magnetic attraction, so that the position of the top pins 27 on the auxiliary movable table 25 corresponds to the core material of the finished carton. After completion, start the main hydraulic push rod 12 and the auxiliary hydraulic push rod 17 to pull the main movable table 13 and the auxiliary movable table 25 to reset respectively, and stack the die-cut cardboard on the placement plate 28. Then, start the electric push rod 201 in the positioning components 2 on both sides above the base 1 to make the electric push rod 201 push the movable plate 203 to move.

[0048] During the process, the movable plate 203 synchronously drives the connecting strip 205 to move, so that the movable pin 206 at one end of the connecting strip 205 slides in the inclined groove 10, and then pushes the movable pin 206 through the groove wall of the inclined groove 10, causing the movable pin 206 to drive the movable plate 203 through the connecting strip 205, so that the movable plate 203 moves horizontally on the connecting block 202 through the connecting groove 204, so that the movable plate 203 slides vertically while being pushed horizontally by the electric push rod 201. Finally, through two L-shaped movable plates 203 facing each other, the vertical and horizontal sides of the movable plates 203 are respectively attached to the side and bottom edges of the cardboard to form a positioning structure.

[0049] Then, the main hydraulic push rod 12 and the auxiliary hydraulic push rod 17 are activated simultaneously. The main hydraulic push rod 12 pushes the main movable table 13 down, causing the pressure plate 15 to contact the cardboard. When the top pin 27 on the main movable table 13 passes through the through hole 32 on the pressure plate 15 and contacts the waste edge, the main movable table 13 stops being pushed down. Meanwhile, the auxiliary hydraulic push rod 17 pushes the auxiliary movable table 25 up, causing the top pin 27 on the auxiliary movable table 25 to pass through the through hole 32 on the placement plate 28 and contact the finished core material. At this time, the auxiliary movable table 25 continues to be pushed up, causing the top pin 27 to push out the finished core material, so that the finished core material separates from the waste edge.

[0050] During the process, the top pin 27 pushes the pressure plate 15 upward through the finished core material, causing the connecting rod 14 to slide on the main movable table 13 and stretch the connecting spring 35. Then, the rebound of the connecting spring 35 makes the pressure plate 15 press against the finished core material. Finally, the main hydraulic push rod 12 is activated to move the pressure plate 15 away from the finished core material. At this time, the worker takes out the finished core material and then activates the auxiliary hydraulic push rod 17 to pull the auxiliary movable table 25 to move the top pin 27 away from the worktable 6. Then, the electric push rod 201 pulls the movable plate 203 away from the worktable 6 and embeds it into the wall of the base 1.

[0051] Then, the drive motor 19 is started to rotate the threaded rod 20. The threaded sleeve 22 and the threaded rod 20 are used to drive the movable frame 21 to slide along the guide rod 18 and the limiting groove 7. During the process, the fixed block 31 on the connecting frame 29 will be pushed by the push groove 24 on the side plates 23 on both sides of the movable frame 21, which will cause the connecting frame 29 to drive the worktable 6 to rotate around the fixed rod 30. During the process, the fixed block 31 slides along the arc groove 8, which will cause the worktable 6 to tilt, and cause the waste edge left on the worktable 6 to be discharged from the discharge port 3 on both sides of the base 1.

8. A method of using a waste removal machine for cardboard box processing, as described in any one of claims 1-7, characterized in that: The method of use includes the following steps: Before cleaning up the waste, the main hydraulic push rod (12) and the auxiliary hydraulic push rod (17) are activated to push the main moving platform (13) and the auxiliary moving platform (25) to move, causing the main moving platform (13) and the auxiliary moving platform (25) to move closer to the workbench (6). At this time, the workers remove the rubber sleeve (36) that is fitted on the plug (38) and put the removed rubber sleeve (36) on the top material head (37) at one end of the top material pin (27). Then, the plugs (38) of multiple top material pins (27) are inserted into the plug holes (26) on the main moving platform (13) and fixed by the magnetic attraction of the magnetic block (39) and the main moving platform (13), so that the position of the top material pin (27) on the main moving platform (13) corresponds to the waste edge of the core material of the finished carton. Then, insert the connectors (38) of multiple top pins (27) through the through holes (32) on the placement plate (28) into the insertion holes (26) on the auxiliary movable platform (25), and simultaneously use the magnetic attraction block (39) to fix the auxiliary movable platform (25) with magnetic attraction, so that the position of the top pins (27) on the auxiliary movable platform (25) corresponds to the core material of the carton. After completion, start the main hydraulic push rod (12) and the auxiliary hydraulic push rod (17) to pull the main movable platform (13) and the auxiliary movable platform (25) to reset respectively, and stack the die-cut cardboard on the placement plate (28). Then, start the electric push rod (201) in the positioning components (2) on both sides above the base (1) to make the electric push rod (201) push the movable plate (203) to move. During the process, the movable plate (203) synchronously drives the connecting strip (205) to move, so that the movable pin (206) at one end of the connecting strip (205) slides in the inclined groove (10), and then pushes the movable pin (206) through the groove wall of the inclined groove (10), causing the movable pin (206) to drive the movable plate (203) through the connecting strip (205), so that the movable plate (203) moves horizontally on the connecting block (202) through the connecting groove (204), so that the movable plate (203) slides vertically while being pushed horizontally by the electric push rod (201), and finally forms a positioning structure by using the vertical and horizontal sides of the movable plate (203) to adhere to the side and bottom edges of the cardboard respectively through two L-shaped movable plates (203) facing each other. Then, the main hydraulic push rod (12) and the auxiliary hydraulic push rod (17) are started simultaneously. The main hydraulic push rod (12) pushes the main movable table (13) down, causing the pressure plate (15) to contact the cardboard. When the top pin (27) on the main movable table (13) passes through the through hole (32) on the pressure plate (15) and contacts the waste edge, the main movable table (13) is stopped from being pushed down. Meanwhile, the auxiliary hydraulic push rod (17) pushes the auxiliary movable table (25) up, causing the top pin (27) on the auxiliary movable table (25) to pass through the through hole (32) on the placement plate (28) and contact the finished core material. At this time, the auxiliary movable table (25) is pushed up, causing the top pin (27) to push out the finished core material, so that the finished core material is separated from the waste edge. During the process, the top pin (27) pushes the pressure plate (15) upward through the finished core material, causing the connecting rod (14) to slide on the main movable table (13) and stretch the connecting spring (35). Then, the rebound of the connecting spring (35) makes the pressure plate (15) press against the finished core material. Finally, the main hydraulic push rod (12) is activated to make the pressure plate (15) move away from the finished core material. At this time, the worker takes out the finished core material and, after taking it out, activates the auxiliary hydraulic push rod (17) to pull the auxiliary movable table (25) to make the top pin (27) move away from the worktable (6). Then, the electric push rod (201) pulls the movable plate (203) away from the worktable (6) and embeds it into the wall of the base (1). Then start the drive motor (19) to rotate the threaded rod (20). The threaded sleeve (22) and the threaded rod (20) are used to drive the movable frame (21) to slide along the guide rod (18) and the limiting groove (7). During the process, the fixed block (31) on the connecting frame (29) will be pushed by the push groove (24) on the side plates (23) on both sides of the movable frame (21), which will cause the connecting frame (29) to drive the worktable (6) to rotate around the fixed rod (30). During the process, the fixed block (31) slides along the arc groove (8), which will cause the worktable (6) to tilt, and cause the waste edge left on the worktable (6) to be discharged from the discharge port (3) on both sides of the base (1).
