Description

Technical Field

[0001] This invention relates to the field of cardboard box manufacturing technology, specifically to an adjustable cardboard box positioning and punching processing device. Background Technology

[0002] Corrugated cardboard boxes are the most widely used containers in warehousing, logistics, and product packaging. A complete, standardized production process involves the following steps: corrugated base paper lamination, cardboard cutting and slitting, printing, crease marking, and corner cutting, punching handle holes, gluing or stapling, and final packaging and warehousing. The handle hole punching process is performed after the printing and crease marking process and before the gluing and stapling process. It involves punching oblong handle holes on both sides of the unfolded flat corrugated cardboard to facilitate handling and transport. The punching precision directly affects the appearance quality and performance of the cardboard box.

[0003] Traditional positioning mechanisms typically employ independent baffles on both sides, along with front and rear guardrails, to limit movement. These baffles can only achieve unidirectional translational adjustment, resulting in a limited overall adjustment dimension and applicability only to a few cardboard sizes with fixed aspect ratios. When faced with order changes involving multiple sizes and aspect ratios, operators must repeatedly disassemble and calibrate the guardrail positions, leading to lengthy changeover and debugging times and poor production continuity.

This adjustment method allows for multi-dimensional fine-tuning of the right-angle block's angle, length, and position, overcoming the limitations of single diagonal displacement adjustment. It ensures that the right-angle block always precisely conforms to the diagonal right-angle position of the cardboard, achieving convenient adjustment of the positioning component's position.

[0016] 2. This invention uses a starting cylinder.

[0019] The technical solutions in 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.

[0020] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides an adjustable carton positioning and punching processing device, including a workbench 10. A conveying mechanism 11 is provided on the left side of the workbench 10, and a conveying mechanism 12 is provided on the right side of the workbench 10. A positioning mechanism 20 is provided on the top of the workbench 10. The positioning mechanism 20 includes an internal groove inside the workbench 10. A pair of displacement blocks 201 arranged in a mirror image along the diagonal are slidably connected inside the internal groove. A guide rail 211 is slidably connected to the top of the displacement blocks 201. The top of the guide rail 211 is fixedly connected to the internal groove. The displacement blocks 201 pass through the internal groove, and a moving component is provided on the inner side of the displacement blocks 201. A rotatable telescopic component is provided on the top of the displacement blocks 201, and a right-angle block 210 is provided on the inner side of the telescopic component.

[0021] In use, the cardboard is conveyed in a flat state by the conveyor mechanism 11. The cardboard is removed from the conveyor mechanism 11 by manual or machine personnel and laid flat at the top center of the workbench 10. Then, the moving component drives the two displacement blocks 201 to move relative to each other by a fixed distance, so that the inner walls of the right-angle blocks 210 on both sides completely abut against the two opposite corners of the cardboard, achieving the effect of positioning the cardboard before punching.

[0022] refer to Figure 3 Preferably, the telescopic component includes a connecting frame 206, with a sliding plate 207 slidably connected inside the connecting frame 206. The bottom of the sliding plate 207 has a through hole, and a stud 209 is installed inside the through hole. The bottom of the stud 209 is fixedly connected to the right-angle block 210, and a nut is threaded onto the outside of the stud 209, abutting against the top surface of the sliding plate 207. By sliding the sliding plate 207 inside the connecting frame 206, the telescopic length of the right-angle block 210 can be adjusted. With the locking engagement of the stud 209 and the nut, the vertical installation position of the right-angle block 210 can be fixed after adjustment, adapting to cardboard of different thicknesses and corner specifications, thus improving positioning adaptability.

[0023] refer to Figure 3 Furthermore, a connecting block 202 is fixedly connected to the top of the displacement block 201, a fixing rod 203 is fixedly connected to the top of the connecting block 202, the fixing rod 203 is rotatably connected to the connecting frame 206, a stud 204 is fixedly connected to the top of the fixing rod 203, and a nut 205 is threadedly connected to the outer side of the stud 204.

[0024] When changing to different sizes of cardboard, since the length and width of the cardboard change, the movement distance of the single adjustment component cannot make the right-angle block 210 fit perfectly against the diagonal of the cardboard. Therefore, the initial position of the right-angle block needs to be adjusted before punching holes in cardboard of different specifications.

[0025] During adjustment, loosen nut 205, locking bolt 208, and nut in sequence to change the right-angle block 210 from the locked state to the adjustable state. Then, move it to the positioning distance using the moving component. Next, rotate the angle of the connecting frame 206 according to the position of the corresponding corner of the target cardboard. Adjust the length of the telescopic component by sliding the sliding plate 207 within the connecting frame 206. Finally, rotate the right-angle block 210 so that it maintains a right angle against the inner wall of the cardboard corner after adjustment. Finally, tighten nut 205, locking bolt 208, and nut in sequence to lock the adjusted position. This adjustment method allows for multi-dimensional fine-tuning of the angle, length, and position of the right-angle block 210, overcoming the limitations of single diagonal displacement adjustment. It ensures that the right-angle block 210 always accurately fits the diagonal right-angle position of the cardboard, avoiding positioning offset and adapting to the positioning needs of corrugated cardboard with various aspect ratios.

[0026] refer to Figure 4Furthermore, the moving component includes a rotating rod 212 rotatably connected to the center of the inner side of the built-in groove. Gear 1 213 and gear 218 are fixedly connected to the outer side of the rotating rod 212 from top to bottom. A pair of inclined and centrally symmetrical toothed plates 214 mesh with the outer side of gear 1 213. Gear 1 214 is fixedly connected to the corresponding side displacement block 201. Gear 2 218 has a toothed plate 217 meshing with its right side. An electric telescopic rod 216 is provided on the front side of toothed plate 217. The base of electric telescopic rod 216 is fixedly connected to the front surface wall of the built-in groove. The output end of electric telescopic rod 216 is fixedly connected to toothed plate 217.

[0027] When the output end of the electric telescopic rod 216 extends, it drives the toothed plate 217 to move forward. Through the transmission between the toothed plate 217 and the gear 218, the rotating rod 212 and the gear 213 rotate counterclockwise. Then, through the transmission between the gear 213 and the two toothed plates 214, the displacement blocks 201 on both sides move towards each other. Similarly, when the output end of the electric telescopic rod 216 retracts, it drives the rotating rod 212 and the gear 213 to rotate clockwise. Through the corresponding toothed plates 214, it drives the displacement blocks 201 on both sides to move away from each other. Since the stroke of the electric telescopic rod 216 is fixed each time it extends and retracts, and with the synchronous transmission structure of the gear and rack, the movement distance of the displacement blocks 201 on both sides is consistent and the action is synchronized. This effectively avoids the deviation of the positioning displacement on both sides, ensures the consistency and symmetry of the cardboard positioning each time, and improves the dimensional accuracy of batch punching.

[0028] refer to Figure 2 , Figure 5 The top of the workbench 10 is provided with a punching mechanism 30. The punching mechanism 30 includes a support plate 301 fixedly connected to the rear side of the workbench 10. A cylinder 302 is fixedly installed at the bottom of the top horizontal plane of the support plate 301. A moving frame 303 is fixedly connected to the output end of the cylinder 302. An adjusting component is provided at the bottom of the moving frame 303. A pair of punches 308 are connected to the bottom of the adjusting component.

[0029] After the cardboard is positioned, cylinder 302 is activated. The output end of cylinder 302 drives the moving frame 303 downward, causing the moving frame 303 and punch 308 to move in the same direction until the punch 308 contacts the designated position on the cardboard and presses down until the target area is cut off. After punching is completed, cylinder 302 drives the moving frame 303 and punch 308 to return to their original position and detach from the cardboard surface. The waste generated by punching can fall off naturally, completing a single cardboard handle hole punching operation. The overall action is simple and stable, and can be adapted to continuous punching processing conditions.

[0030] refer to Figure 5Specifically, the front and rear sides of the movable frame 303 are rotatably connected to a trapezoidal threaded rod 304. The trapezoidal threaded rod 304 extends forward and penetrates the front wall of the movable frame 303, and a throttle is fixedly connected to the front side. A movable block 305 is threadedly connected to the outer side of the trapezoidal threaded rod 304. Slide rails are slidably connected to the left and right sides of the movable block 305, and the outer side of the slide rails is fixedly connected to the corresponding inner wall of the movable frame 303. A displacement component is provided at the bottom of the movable block 305.

[0031] refer to Figure 5 Furthermore, the movable component includes a pair of left-right arranged sliding grooves 306 opened at the bottom of the movable frame 303. An adjusting block 307 is provided inside the sliding groove 306, and the bottom of the adjusting block 307 is fixedly connected to the corresponding punch 308. A slide rail is fixedly connected to the inner rear wall of the sliding groove 306, and the slide rail is slidably connected to the adjusting block 307. An adjusting groove 309 is opened on the front side of the sliding groove 306. A stud 310 is fixedly connected to the front side of the adjusting block 307. The stud 310 passes through the adjusting groove 309 and is threadedly connected to a nut 311 on its outer side. The rear wall of the nut 311 abuts against the front side of the movable block 305.

[0032] Rotating the handle drives the trapezoidal threaded rod 304 to rotate, causing the moving block 305 to slide back and forth, thus achieving overall adjustment of the front and back positions of the punches 308. After loosening the second nut 311, the left and right distance between the two punches 308 can be adjusted individually by sliding the adjusting block 307 along the sliding groove 306. After adjustment, tightening the second nut 311 locks the position. This structure can flexibly adapt to the requirements of handle hole spacing and position for different sizes of cartons without replacing the overall punching component, making the equipment more versatile.

[0033] refer to Figure 6 , Figure 7 A material handling mechanism 40 is provided on the front side of the workbench 10. The material handling mechanism 40 includes a guide box 401. A lead screw 402 is rotatably connected to the left and right sides inside the guide box 401. A motor 403 is fixedly installed on the right side of the guide box 401. The output end of the motor 403 is fixedly connected to the lead screw 402. A translation block 404 is threadedly connected to the outside of the lead screw 402. A sliding sleeve 405 that can move up and down is sleeved on the outside of the translation block 404. A mounting plate 406 is fixedly connected to the rear side of the sliding sleeve 405. Vacuum suction cups 407 are fixedly installed at the four corners of the bottom of the mounting plate 406.

[0034] refer to Figure 7 Preferably, the internal cross-section of the sliding sleeve 405 is adapted to the side size of the translation block 404, which can limit the lateral and longitudinal offset between the sliding sleeve 405 and the translation block 404, retain only the vertical sliding degree of freedom, ensure the stability of the sliding sleeve 405 during movement, and avoid swaying and offset during movement.

[0035] In use, a set of vacuum suction cups 407 adsorbs the cardboard on the conveyor mechanism 11. The motor 403 is started by an external power source. The output of the motor 403 drives the lead screw 402 to rotate, thereby moving the translation block 404 and the sliding sleeve 405 from the left end to the right end. Simultaneously, the mounting plate 406 and the cardboard adsorbed by the vacuum suction cups 407 move to the right. After reaching the designated position on the worktable 10, the sliding sleeve 405 moves down and releases the suction, placing the cardboard down. Then, the output of the motor 403 reverses, driving the sliding sleeve 405 and the mounting plate... Moving 406 a short distance to the left does not affect the positioning and punching of the cardboard. After the cardboard is punched, the output of motor 403 rotates again, driving the sliding sleeve 405 and mounting plate 406 to move to the right. When the sliding sleeve 405 moves to the position of the cardboard, it moves down so that the vacuum suction cup 407 presses against the surface of the cardboard and adsorbs it again. The cardboard moves to the right along with the sliding sleeve 405 and moves to the top of the second conveyor mechanism 12. Finally, the adsorption of the vacuum suction cup 407 is released, and the cardboard falls onto the surface of the second conveyor mechanism 12 and is conveyed away. The output of motor 403 reverses and moves the mounting plate 406 to the leftmost side.

[0036] refer to Figure 7 Furthermore, a guide plate 408 is fixedly connected to the front inner wall of the guide box 401. The guide plate 408 is inclined at the left end, concave in the middle, and horizontal on the right side. A roller 409 is fixedly installed on the rear side of the sliding sleeve 405. The roller 409 contacts the upper surface of the guide plate 408.

[0037] In use, the roller 409 supports the position of the sliding sleeve 405. When the lead screw 402 rotates and drives the translation block 404 and the sliding sleeve 405 to move, the height of the sliding sleeve 405 is affected by the contact position between the roller 409 and the guide plate 408. When the roller 409 rolls from left to right on the left end of the guide plate 408, the sliding sleeve 405 moves to the right and upward at the same time to achieve a lifting action, which can effectively lift the cardboard on the conveying mechanism 11 and separate it from the conveying mechanism 11. When the roller 409 rolls to the recessed position in the middle of the guide plate 408, the sliding sleeve 405 moves to the right and downward at the same time to place the cardboard on the top of the worktable 10. When the roller 409 rolls to the horizontal position on the right side of the guide plate 408, the sliding sleeve 405 maintains a stable horizontal height, which is convenient for accurately adsorbing the cardboard after punching. The entire process relies on mechanical trajectory to realize the automatic lifting, lowering, and translation of the cardboard. No additional lifting drive components are required. The structure is simple and the transfer accuracy is high, which can realize the automated loading and unloading operation of the equipment.

[0038] Based on the above technical solution, this embodiment of the invention also provides a working principle for an adjustable carton positioning and punching processing device, including the following: Loosening nut 205, locking bolt 208, and nut in sequence; changing the right-angle block 210 from a locked state to an adjustable state; moving it to the positioning distance via the moving component; rotating the angle of the connecting frame 206 according to the position of the corresponding corner of the target cardboard; adjusting the length of the telescopic component by sliding the sliding plate 207 within the connecting frame 206; finally rotating the right-angle block 210 so that it maintains a right angle against the inner wall of the cardboard corner after adjustment; and finally tightening nut 205, locking bolt 208, and nut in sequence to lock the adjusted position. This adjustment method allows for multi-dimensional fine-tuning of the angle, length, and position of the right-angle block 210, overcoming the limitations of a single diagonal displacement adjustment, ensuring that the right-angle block 210 always accurately fits the diagonal right-angle position of the cardboard, avoiding positioning offset, and adapting to the positioning needs of corrugated cardboard with various aspect ratios.

[0039] 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.
