Description

Technical Field

[0001] This invention belongs to the field of paper box processing, specifically a paper box slotting mechanism used in paper box production lines. Background Technology

[0002] Cardboard boxes are a widely used type of shockproof product and an indispensable part of modern logistics. They play an important role in containing, protecting, and aesthetically pleasing products. Cardboard boxes are generally made by bonding and pressing face paper, liner paper, and core paper together to form cardboard. Then, slots are cut into the cardboard box using a cardboard box slotting machine, and the boxes are folded and glued along the slots.

[0003] When slotting cardboard boxes, the cut cardboard is fed into the cardboard slotting machine by a conveyor belt. The upper drive roller rotates under the drive of the motor, which drives the cutter head to rotate, so that the slotting blades installed on the cutter head slot the cardboard. The slotting blade is an important part of the cardboard slotting machine that performs the slotting work. The slotting blade directly affects the slotting quality of the cardboard box, thus affecting the overall quality of the cardboard box.

[0004] Most existing slotting blades are either curved blades or curved serrated blades. When the cardboard slotting machine is working, the slotting blade is close to the support roller on the lower drive roller. If the operation is not careful, the slotting blade may come into contact with the support roller. After a long period of use, the slotting blade will wear excessively. At the same time, the ends of the slotting blade wear the most severely. Even if the slotting blade is ground, the accuracy of the slotting blade will be reduced, and the entire slotting blade will have to be replaced, which greatly increases the cost.

[0017] 1. The cardboard box slotting mechanism for a cardboard box production line described in this invention comprises a fan-shaped mounting base, a mounting rod, and slotting blades. When the first slotting blade in the rotation direction of the fan-shaped mounting base is excessively worn or damaged due to collision, the operator can replace the damaged or worn slotting blade with a intact slotting blade in the middle of the fan-shaped mounting base. When an excessively worn slotting blade is unusable, only one excessively worn blade needs to be replaced, thereby reducing the time spent on replacing and repairing slotting blades during cardboard box slotting and improving the production efficiency of cardboard boxes. Simultaneously, the interchangeability of multiple slotting blades reduces the probability of excessive wear of the first slotting blade in the rotation direction of the fan-shaped mounting base, improving the quality of cardboard slotting and consequently improving the quality of cardboard box production.

The multiple long bolts provide fixation, reducing the probability of the mounting rod wobbling inside the fixing opening. When moving the slide block, a hex wrench is used to rotate the rotating rod, causing the gears to rotate. The gears mesh with the rack, causing the gears to rotate and move along the rack, thus moving the slide block along the mounting groove. This meshing movement between the gears and rack improves the accuracy of the slide block's movement, making it easier for workers to control the position of the slotting cutter and improving the accuracy of the slotting cutter's position adjustment.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 2 As shown in the embodiment of the present invention, the cardboard box slotting mechanism for a cardboard box production line includes a frame 1; an upper drive roller 2 is installed above the slotting position of the frame 1, and a lower drive roller 3 is installed below the slotting position of the frame 1. A drive unit is provided on the frame 1, and the drive unit is connected to the upper drive roller 2 and the lower drive roller 3 respectively. Multiple support rollers 4 are installed on the outer ring of the lower drive roller 3, and multiple cutter discs 5 are installed on the outer ring of the upper drive roller 2. The multiple cutter discs 5 correspond one-to-one with the multiple support rollers 4. A fan-shaped mounting seat 6 is bolted to one side of the cutter disc 5. Multiple mounting grooves 9 are evenly opened on the arc surface of the fan-shaped mounting seat 6 near the outer ring of the cutter disc 5. A mounting rod 7 is installed inside the mounting groove 9, and a slotting knife 8 is fixedly connected to the end of the mounting rod 7 away from the mounting groove 9.

[0031] During operation, the drive unit drives the upper drive roller 2 and the lower drive roller 3 to rotate, which in turn drives the support roller 4 and the cutter head 5 to rotate. The cutter head 5 drives the fan-shaped mounting base 6 to rotate, which in turn drives the slotting knife 8 to slit the top surface of the cardboard. When the first slotting knife 8 in the rotation direction of the fan-shaped mounting base 6 is excessively worn or damaged due to collision, the operator can replace the damaged or worn slotting knife 8 with the intact slotting knife 8 in the middle of the fan-shaped mounting base 6. When the excessively worn slotting knife is unusable, only one excessively worn knife needs to be replaced, thereby reducing the time spent on replacing and repairing the slotting knife 8 when the cardboard slotting machine is shut down, and improving the production efficiency of the cardboard box. At the same time, multiple slotting knives 8 can be replaced and used, thereby reducing the probability of excessive wear of the first slotting knife 8 in the rotation direction of the fan-shaped mounting base 6, improving the quality of cardboard slotting, and thus improving the quality of cardboard box production.

[0032] like Figures 2 to 5 As shown, a slide block 10 is slidably installed inside the mounting groove 9. A fixing port 11 is provided at one end of the slide block 10 near the opening of the mounting groove 9. The inner wall of the fixing port 11 is slidably engaged with the end of the mounting rod 7 away from the slotting cutter 8. Multiple screw holes 12 are provided on the side wall of the fixing port 11 near the cutter disc 5. Multiple first through holes 13 are provided on the side wall of the fixing port 11 away from the cutter disc 5. Multiple second through holes 14 are provided at the end of the mounting rod 7 away from the slotting cutter 8. The multiple first through holes 13, multiple second through holes 14 and multiple screw holes 12 correspond one-to-one. A long bolt 15 is installed in the internal thread of the screw hole 12. The long bolt 15 slides through the inner ring of the first through hole 13 and the second through hole 14. The bolt head of the long bolt 15 has an internal hexagonal groove. Multiple locking structures are provided at the end of the slide block 10 away from the mounting rod 7.

[0033] During operation, when installing or replacing the grooving knife 8, insert the mounting rod 7 into the fixing port 11 of the slide 10, aligning the first through hole 13, the second through hole 14, and the screw hole 12. Use a long bolt 15 to pass through the first through hole 13 and the second through hole 14, and thread the threaded end of the long bolt 15 into the screw hole 12 to fix the mounting rod 7 inside the fixing port 11. By fixing it with multiple long bolts 15, the probability of the mounting rod 7 shaking inside the fixing port 11 is reduced. By sliding the slide 10 inside the mounting groove 9, the distance of the grooving knife 8 extending out of the cutter disc 5 can be adjusted, thereby controlling the grooving depth of the cardboard.

[0034] like Figures 3 to 6As shown, the locking structure includes a double-ended screw 16 and a concave clamping block 17. The slide block 10 has multiple pairs of sliding grooves 18 at the end away from the mounting rod 7. A double-ended screw 16 is rotatably installed between each pair of sliding grooves 18. A concave clamping block 17 is slidably installed inside the sliding groove 18. The concave openings of each pair of concave clamping blocks 17 are arranged opposite to each other. The double-ended screw 16 passes through the middle of the concave clamping block 17, and the double-ended screw 16 is threadedly engaged with the concave clamping block 17. The end of the double-ended screw 16 is provided with an internal hexagonal groove.

[0035] During operation, after adjusting the position of the slide block 10 inside the mounting groove 9, the double-ended screw 16 is rotated using a hex wrench, which drives a pair of concave clamps 17 to slide relative to each other inside the slide groove 18, so that the two ends of the concave clamps 17 press against the inner wall of the mounting groove 9, thus fixing the slide block 10 inside the mounting groove 9 and achieving the fixation of the slide block 10.

[0036] like Figure 6 As shown, rubber blocks 19 are fixed to both ends of the concave clamping block 17, and anti-slip textures are provided on the side of the rubber block 19 near the sliding groove 18.

[0037] By using the rubber block 19, the two ends of the concave clamp 17 press against the inner wall of the mounting groove 9, causing the rubber block 19 to deform, reducing the probability of the concave clamp 17 sliding, thereby further improving the fixing firmness of the slide block 10.

[0038] like Figures 2 to 6 As shown, a circular groove 20 is provided at the end of the slide block 10 away from the mounting rod 7. The circular groove 20 is located between adjacent locking structures. The two sides of the circular groove 20 respectively penetrate the two sides of the slide block 10. A rotating rod 21 is rotatably installed inside the circular groove 20. The rotating rod 21 rotatably penetrates the top wall of the circular groove 20. A gear 22 is fixedly connected to the outer ring of the rotating rod 21. The outer wall of the gear 22 slides with the inner wall of the circular groove 20. A rack 23 is fixedly connected to the side wall of the mounting groove 9. The gear 22 and the rack 23 mesh with each other.

[0039] During operation, when moving the slide block 10, the lever 21 is rotated using a hex wrench, which drives the gear 22 to rotate. The gear 22 meshes with the rack 23, causing the gear 22 to rotate and move along the rack 23, thus driving the slide block 10 to slide along the mounting groove 9. The meshing movement between the gear 22 and the rack 23 improves the accuracy of the slide block 10's movement, making it easier for the operator to control the position of the grooving cutter 8 and improving the accuracy of the grooving cutter 8's position adjustment.

[0040] like Figures 5 to 6As shown, the diameter of the first through hole 13 is larger than the diameter of the second through hole 14. The diameter of the second through hole 14 is the same as the diameter of the screw hole 12. A square groove 24 is formed on the outer ring of the second through hole 14 near the first through hole 13. The diameter of the end of the long bolt 15 near the bolt head is larger than the diameter of the threaded end of the long bolt 15, and an annular step is formed on the end of the long bolt 15 near the bolt head. An annular plate 25 is slidably installed on the end of the long bolt 15 near the threaded end. The outer diameter of the annular plate 25 is larger than the diameter of the first through hole 13, and the outer diameter of the annular plate 25 is smaller than the diameter of the second through hole 14. A rubber ring 26 is fixed between the annular plate 25 and the annular step on the end of the long bolt 15 near the bolt head.

[0041] During operation, when the long bolt 15 passes through the first through hole 13, it drives the ring plate 25 and the rubber ring 26 through the first through hole 13, so that the ring plate 25 and the rubber ring 26 enter the interior of the square groove 24. The ring plate 25 is blocked by the bottom surface of the square groove 24, so that the bottom end of the long bolt 15 passes through the second through hole 14. When the long bolt 15 is screwed into the screw hole 12, the annular step of the ring plate 25 and the long bolt 15 squeezes the rubber ring 26, so that the rubber ring 26 fills and squeezes into the interior of the square groove 24, thereby fixing and clamping the long bolt 15, thereby reducing the probability of the long bolt 15 loosening.

[0042] like Figure 7 As shown, circular holes 27 are provided on both sides of the square groove 24. A sliding column 28 is slidably installed inside the circular hole 27. A circular plate 29 is fixedly connected to one end of the sliding column 28 near the square groove 24. The diameter of the circular plate 29 is larger than the diameter of the circular hole 27. A spring 30 is fixedly connected between the circular plate 29 and the step of the circular hole 27. The inner ring of the spring 30 is sleeved on the outer ring of the sliding column 28.

[0043] During operation, when the rubber ring 26 fills and squeezes into the square groove 24, it pushes the circular plate 29 to contact the side wall of the square groove 24, and pushes the sliding column 28 to squeeze the side wall of the fixing port 11, thereby improving the fixation degree of the mounting rod 7 inside the fixing port 11.

[0044] like Figure 7 As shown, a plurality of arc-shaped steel plates 31 are fixedly connected around the end of the sliding column 28 away from the square groove 24. The arc-shaped steel plates 31 are bent toward the axis of the sliding column 28. A top plate 32 is fixedly connected to the end of the plurality of arc-shaped steel plates 31 away from the sliding column 28. A rubber column 33 is fixedly connected between the top plate 32 and the sliding column 28.

[0045] During operation, when the sliding column 28 slides towards the side wall of the fixed opening 11, it pushes the top plate 32 to contact the side wall of the fixed opening 11, causing the arc-shaped steel sheet 31 to bend towards the axis of the sliding column 28. At the same time, the rubber column 33 is compressed, making the compression on the side wall of the fixed opening 11 elastic. When the mounting rod 7 shakes, it is reset and fixed, thereby improving the accuracy and stability of the mounting rod 7 in the position inside the fixed opening 11.

[0046] like Figures 2 to 3 As shown, a fixing plug 34 is slidably installed on the outer ring of the mounting rod 7, and the protruding outer wall of the fixing plug 34 slides in cooperation with the inner wall of the mounting groove 9.

[0047] By using the fixed plug 34, the gap between the mounting rod 7 and the mounting groove 9 is filled, thereby reducing the torque between the mounting rod 7 and the grooving cutter 8. When the grooving cutter 8 is impacted, not only is the probability of the mounting rod 7 shaking reduced, but the probability of the mounting rod 7 breaking is also reduced.

[0048] like Figure 8 As shown, the outer wall of the mounting rod 7 is evenly provided with multiple scale grooves 35, and the fixing plug 34 is fixedly connected to a pointer 36 on the side near the grooving knife 8;

[0049] During operation, the pointer 36 and the scale groove 35 allow the operator to accurately adjust the distance of the mounting rod 7 sliding out of the mounting groove 9, thereby facilitating the adjustment of the cutting edges of multiple grooving cutters 8 to the same arc, reducing the probability of misalignment of multiple grooving cutters 8 and damage to the grooving cutters 8.

[0050] During operation: Insert the mounting rod 7 into the fixing port 11 of the slide block 10, aligning the first through hole 13, the second through hole 14, and the screw hole 12. When the long bolt 15 passes through the first through hole 13, it drives the ring plate 25 and the rubber ring 26 through the first through hole 13, allowing the ring plate 25 and the rubber ring 26 to enter the square groove 24. The ring plate 25 is blocked by the bottom surface of the square groove 24, allowing the bottom end of the long bolt 15 to pass through the second through hole 14. When the long bolt 15 is screwed into the screw hole 12, the ring plate 25 and the long bolt 15... The annular step squeezes the rubber ring 26, causing the rubber ring 26 to be filled and squeezed inside the square groove 24, thus fixing and clamping the long bolt 15. At the same time, when the rubber ring 26 is filled and squeezed inside the square groove 24, it pushes the circular plate 29 to contact the side wall of the square groove 24. When the sliding column 28 slides towards the side wall of the fixing port 11, it pushes the top plate 32 to contact the side wall of the fixing port 11, causing the arc-shaped steel sheet 31 to bend towards the axis of the sliding column 28. At the same time, the rubber column 33 is compressed, which improves the fixation degree of the mounting rod 7 inside the fixing port 11.

[0051] Using a hex wrench to rotate the lever 21, the gear 22 rotates, and the gear 22 meshes with the rack 23, causing the gear 22 to rotate and move along the rack 23, which in turn causes the slide 10 to slide along the mounting groove 9, pushing the mounting rod 7 to move and adjusting the distance of the grooving knife 8 extending from the cutter disc 5 to control the grooving depth of the cardboard. After adjusting the position of the slide 10 inside the mounting groove 9, using a hex wrench to rotate the double-ended screw 16, a pair of concave clamps 17 slide relative to each other inside the groove 18, so that the two ends of the concave clamps 17 press against the inner wall of the mounting groove 9, fixing the slide 10 inside the mounting groove 9.

[0052] The drive unit drives the upper drive roller 2 and the lower drive roller 3 to rotate, which in turn drives the support roller 4 and the cutter head 5 to rotate. The cutter head 5 drives the fan-shaped mounting base 6 to rotate, which in turn drives the slotting knife 8 to slit the top surface of the cardboard. When the first slotting knife 8 in the rotation direction of the fan-shaped mounting base 6 is excessively worn or damaged by collision, the operator can replace the damaged or worn slotting knife 8 with the intact slotting knife 8 in the middle of the fan-shaped mounting base 6. When the excessively worn slotting knife is unusable, only one excessively worn knife needs to be replaced, thereby reducing the time for replacing and repairing the slotting knife 8 when the cardboard slotting machine is shut down, and improving the production efficiency of the cardboard box. At the same time, the replacement and use of multiple slotting knives 8 reduces the probability of excessive wear of the first slotting knife 8 in the rotation direction of the fan-shaped mounting base 6, improves the quality of cardboard slotting, and thus improves the quality of cardboard box production.
