Description

Technical Field

[0001] This utility model relates to the field of cardboard production technology, and more specifically, to a die-cutting device for cardboard production. Background Technology

[0002] Cardboard is a general term for a type of thick paper that falls between paper and cardboard. It can be used to make various packaging boxes, serving both protective and decorative functions. White cardboard and silver cardboard are the mainstream choices due to their low cost or metallic texture. They are used for postcards, greeting cards, album liners, etc. They need to have properties such as water resistance or softness. For example, when used to make postcards, large-sized cardboard needs to be cut into strips of the corresponding size by a die-cutting device, so that it can be cut into normal postcard sizes later.

[0003] Some existing die-cutting devices for cardboard production may not have a tension adjustment structure. During the cardboard conveying process, the cardboard may become loose, resulting in irregular cutting and affecting the processing quality of the product.

[0004] Therefore, we propose a die-cutting device for cardboard production. Utility Model Content

[0005] To solve the above problems, this utility model provides a die-cutting device for cardboard production, which adopts the following technical solution:

[0006] A die-cutting device for cardboard production includes a base, a first mounting frame and a second mounting frame provided on the side wall of the base, a first mounting plate fixedly mounted on both sides of the base, and the first mounting frame located between the first mounting plate and the second mounting frame.

[0007] A unwinding rod is provided between the tops of the two first mounting plates. Each of the tops of the two first mounting plates is provided with a placement groove that matches the unwinding rod. Two symmetrically distributed limiting discs are fixedly sleeved on the side wall of the unwinding rod. A first cylinder is fixedly installed on the side of one of the first mounting plates away from the base. A drive assembly is provided between the first cylinder and the unwinding rod.

[0008] Two symmetrically distributed third support rods are rotatably installed inside the first mounting frame. A third mounting plate is provided inside the first mounting frame and is located between the two third support rods. A second cylinder is fixedly installed at the top of the first mounting frame. The piston shaft of the second cylinder slides through the first mounting frame and is fixedly connected to the top of the third mounting plate. A tension adjustment component is provided at the bottom of the third mounting plate.

[0009] The second mounting frame has a second support rod and a first support rod that are rotatably installed on the inner wall of the side of the second mounting frame close to the first mounting frame. A second telescopic rod is fixedly installed on the inner wall of the top of the second mounting frame. A frame is fixedly installed at the end of the second telescopic rod. A second conveyor belt is provided inside the frame. A pressing component is provided on the side of the frame away from the first mounting frame. A cutting component is provided inside the second mounting frame. A groove is opened at the top of the base. A first conveyor belt is provided in the groove.

[0010] By adopting the above technical solution, when using this equipment, the operator places the unwinding rod, which is wrapped with jammed paper, on top of the two first mounting plates, so that the unwinding rod engages with the placement slots opened on the top of the two first mounting plates. The side wall of the unwinding rod is equipped with a limiting plate, which not only restricts the paper jam, but also has opposite sides that fit against the inner side of the first mounting plate on the same side, thus restricting and positioning the unwinding rod. After the unwinding rod is placed, the operator assembles the drive assembly with the opposite end of the unwinding rod. Then, the operator pulls the end of the jammed paper through the third support rod, tension adjustment assembly, second support rod, first support rod, and second conveyor belt in sequence. The drive assembly drives the unwinding rod to rotate, thus unwinding the jammed paper. The second telescopic rod drives the frame and the second conveyor belt to descend, so that the second conveyor belt contacts the top of the jammed paper. The second conveyor belt has wear-resistant protrusions on its surface, which helps increase the friction between the second conveyor belt and the paper, thus facilitating the movement of the paper and pulling it along. Once the paper has moved the corresponding length, it is fixed by a pressing component and then cut by a cutting component. The cut paper moves onto the first conveyor belt under the pushing force of subsequent paper, and is then conveyed away by the first conveyor belt. A tension adjustment component is located between the two third support rods. The tension adjustment component is raised and lowered by a second cylinder, which in turn pushes the paper downward and deforms it. With the cooperation of the two third support rods, the tension of the paper is adjusted during conveying, which helps maintain the tension of the paper and prevents wrinkles from forming during the conveying process.

[0011] Furthermore, the drive assembly includes a mounting base fixedly installed at the end of the piston shaft of the first cylinder. A geared motor is fixedly installed at the top of the mounting base, and a connecting cylinder is fixedly installed at the end of the output shaft of the geared motor. Two symmetrically distributed limiting blocks are fixedly installed on the side walls of both ends of the unwinding rod. A limiting groove matching the limiting blocks is opened on the inner wall of the connecting cylinder. Two symmetrically distributed stabilizing rods are fixedly installed on one of the first mounting plates away from the base. The ends of the two stabilizing rods away from the first mounting plate on the same side slide through the mounting base.

[0012] By adopting the above technical solution, after the unwinding rod is placed, the first cylinder drives the mounting base, the reduction motor, and the connecting cylinder to move synchronously towards the unwinding rod, so that the connecting cylinder is sleeved on the side wall of the unwinding rod, which can serve to assemble the connecting cylinder and the unwinding rod. Two symmetrically distributed limit blocks are fixedly installed on both sides of the unwinding rod. The inner wall of the connecting cylinder has a limit groove that matches the limit blocks. When the connecting cylinder moves towards the unwinding rod, the operator manually adjusts the connecting cylinder to align the limit groove with the limit block installed on the side wall of the unwinding rod. Then, the first cylinder drives the connecting cylinder to move, so that the limit groove and the limit block engage, which helps to maintain the stability of the connection between the connecting cylinder and the unwinding rod. After the connecting cylinder and the unwinding rod are sleeved, the reduction motor drives the connecting cylinder to rotate synchronously with the unwinding rod, which can serve to lock the unwinding paper. The engagement and positioning of the connecting cylinder and the unwinding rod facilitates the subsequent disassembly and assembly of the unwinding rod.

[0013] Furthermore, the tension adjustment assembly includes two support blocks located below the third mounting plate, with an adjustment rod rotatably mounted between the two support blocks. Two symmetrically distributed pillars are fixedly mounted at the bottom of the third mounting plate, with movable grooves at the bottom of each pillar. Support rods are slidably mounted in each of the two movable grooves, and springs are fixedly connected between the top of each support rod and the inner wall of the top of the movable groove on the same side. The bottom of each support rod is fixedly connected to the top of the support block on the same side.

[0014] By adopting the above technical solution, the worker passes the cardboard through the two third support rods and the adjusting rod in sequence. Then, the second cylinder drives the third mounting plate, support column, support rod, and adjusting rod to rise and fall synchronously. The adjustment rod and the two third support rods work together to adjust the tension of the cardboard during transport, which helps to maintain the tightness of the cardboard during transport and thus helps to prevent the cardboard from becoming loose during transport. This helps to maintain the transport effect of the cardboard. When the adjusting rod pushes the cardboard, the support block pushes the support rod on the same side to slide in the movable groove on the same side. The support rod pushes the spring on the same side to contract. The spring gives the adjusting rod a rebound force, which can play a buffering role and help to prevent the cardboard from tearing due to the large pushing force.

[0015] Furthermore, each of the two support columns has two symmetrically distributed sliding grooves on its sidewalls. The two sliding grooves on the same side are connected to the movable groove on the same side. A slider is slidably installed in each sliding groove, and the two sliders on the same side are fixedly connected to the upper sidewall of the support rod on the same side.

[0016] By adopting the above technical solution, when the support rod slides in the movable groove on the same side, the support rod slides in the sliding groove on the same side along with the slider. Through the cooperation of the slider and the sliding groove, the positioning support rod is restricted, which helps to maintain the stability of the support rod's lifting and lowering, and also helps to prevent the support rod from leaving the movable groove on the same side.

[0017] Furthermore, the pressing assembly includes a second mounting plate fixedly installed on the side of the frame away from the first mounting frame. A pressing plate is provided below the second mounting plate. Two first telescopic rods symmetrically distributed are fixedly installed at the bottom end of the second mounting plate, and the ends of the two first telescopic rods are fixedly connected to the top end of the pressing plate.

[0018] By adopting the above technical solution, before the equipment cuts the paper, the pressing plate is driven down by the first telescopic rod to contact the top of the paper, which can press and fix the paper, thus helping to maintain the stability of the paper during subsequent cutting.

[0019] Furthermore, the cutting assembly includes a cutter disposed within a second mounting frame, a third cylinder fixedly mounted at the top of the second mounting frame, the piston shaft of the third cylinder slidingly passing through the second mounting frame, and the end of the piston shaft of the third cylinder being fixedly connected to the top of the cutter.

[0020] By adopting the above technical solution, after the paper is fixed, the cutter is driven to descend by the third cylinder. The cutter contacts the paper under the acceleration of the third cylinder, and thus achieves the cutting function.

[0021] Furthermore, positioning rings are fixedly fitted on the side walls of both ends of the unwinding rod, and positioning grooves matching the positioning rings on the same side are opened on the inner walls of both placement slots.

[0022] By adopting the above technical solution, positioning rings are fitted on both sides of the unwinding rod, and positioning grooves matching the positioning rings are opened on the inner wall of the placement groove. The engagement of the positioning rings and positioning grooves plays a role in restricting and positioning the unwinding rod, which helps to maintain the stability of the unwinding rod placement.

[0023] In summary, this utility model has the following beneficial technical effects:

[0024] (1) In this utility model, the tension adjustment component is set to adjust the tension of the paper during the paper feeding process, so as to maintain an effective tension during the paper feeding process, thereby helping to avoid the paper from becoming loose during the feeding process and helping to maintain the processing quality of the equipment.

[0025] (2) In this utility model, the driving component is set to drive the unwinding rod to rotate, thereby achieving the effect of flipping the paper. The second telescopic rod drives the frame and the second conveyor belt to descend, so that the second conveyor belt contacts the top of the paper. The surface of the second conveyor belt is provided with wear-resistant protrusions, which helps to increase the friction between the second conveyor belt and the paper, thereby facilitating the operation of the second conveyor belt to transport the paper and playing the role of pulling the paper to move.

Two symmetrically distributed stabilizing rods are fixedly installed on one of the first mounting plates 2 away from the base 1. The ends of the two stabilizing rods away from the first mounting plate 2 on the same side slide through the mounting seat 4.

[0037] When using the device, the operator places the unwinding rod 8, which is wrapped with paper jam, on top of the two first mounting plates 2, so that the unwinding rod 8 engages with the placement slots 33 opened on the top of the two first mounting plates 2. The side wall of the unwinding rod 8 is provided with a limiting plate, which not only restricts the paper jam, but also the opposite side of the two limiting plates is attached to the inner side of the first mounting plate 2 on the same side, which restricts and positions the unwinding rod 8. The side walls at both ends of the unwinding rod 8 are fitted with positioning rings 35, and the inner wall of the placement slots 33 is provided with positioning slots 34 that match the positioning rings 35. The engagement of the positioning rings 35 and the positioning slots 34 restricts and positions the unwinding rod 8, which helps to maintain the stability of the unwinding rod 8.

[0038] After the unwinding rod 8 is placed, the first cylinder 3 drives the mounting base 4, the reduction motor 5, and the connecting cylinder 6 to move synchronously towards the unwinding rod 8, so that the connecting cylinder 6 is fitted onto the side wall of the unwinding rod 8, thus assembling the connecting cylinder 6 and the unwinding rod 8. Two symmetrically distributed limiting blocks 7 are fixedly installed on both sides of the unwinding rod 8. The inner wall of the connecting cylinder 6 has a limiting groove that matches the limiting blocks 7. When the connecting cylinder 6 moves towards the unwinding rod 8, the operator manually adjusts the connecting cylinder 6 so that the limiting groove is aligned with the limiting block 7 installed on the side wall of the unwinding rod 8. Then, the first cylinder 3 drives the connecting cylinder 6 to move, so that the limiting groove and the limiting block 7 engage, which helps to maintain the stability of the connection between the connecting cylinder 6 and the unwinding rod 8. After the connecting cylinder 6 and the unwinding rod 8 are fitted together, the reduction motor 5 drives the connecting cylinder 6 to rotate synchronously with the unwinding rod 8, which can play the role of unwinding and jamming paper. The engagement and positioning of the connecting cylinder 6 and the unwinding rod 8 facilitates the subsequent disassembly and assembly of the unwinding rod 8.

[0039] Two symmetrically distributed third support rods 25 are rotatably installed inside the first mounting frame 9. A third mounting plate 26 is provided inside the first mounting frame 9, located between the two third support rods 25. A second cylinder 13 is fixedly installed at the top of the first mounting frame 9. The piston shaft of the second cylinder 13 slides through the first mounting frame 9 and is fixedly connected to the top of the third mounting plate 26. A tension adjustment assembly is provided at the bottom of the third mounting plate 26. The tension adjustment assembly includes two support blocks 36 located below the third mounting plate 26. An adjustment rod 24 is rotatably installed between the two support blocks 36. Two symmetrically distributed pillars 28 are fixedly installed at the bottom of the third mounting plate 26. Each of the two pillars 28 has a movable groove 32 at its bottom. A support rod 27 is slidably installed in each of the two movable grooves 32. A spring 31 is fixedly connected between the top of each support rod 27 and the inner wall of the top of the movable groove 32 on the same side. The bottom of each support rod 27 is fixedly connected to the top of the support block 36 on the same side.

[0040] After the worker passes the cardboard through the two third support rods 25 and the adjusting rod 24 in sequence, the second cylinder 13 drives the third mounting plate 26, the support column 28, the support rod 27 and the adjusting rod 24 to rise and fall synchronously. The adjustment rod 24 and the two third support rods 25 work together to adjust the tension of the cardboard during transport, which helps to maintain the tightness of the cardboard during transport and thus helps to prevent the cardboard from becoming loose during transport, thus maintaining the transport effect of the cardboard. When the adjusting rod 24 pushes the cardboard, the support block 36 pushes the support rod 27 on the same side to slide in the movable groove 32 on the same side. The support rod 27 pushes the spring 31 on the same side to contract. The spring 31 gives the adjusting rod 24 a rebound force, which can play a buffering role and help to prevent the cardboard from tearing due to the large pushing force.

[0041] Two symmetrically distributed sliding grooves 30 are provided on the side walls of the two support columns 28. The two sliding grooves 30 on the same side are connected to the movable groove 32 on the same side. A slider 29 is slidably installed in each sliding groove 30. The two sliders 29 on the same side are fixedly connected to the upper side wall of the support rod 27 on the same side. When the support rod 27 slides in the movable groove 32 on the same side, the support rod 27 slides in the sliding groove 30 on the same side along with the slider 29. Through the cooperation of the slider 29 and the sliding groove 30, the positioning support rod 27 is restricted, which helps to maintain the stability of the lifting and lowering of the support rod 27 and helps to prevent the support rod 27 from disengaging from the movable groove 32 on the same side.

[0042] The second mounting frame 10 has a second support rod 23 and a first support rod 22 rotatably mounted on the inner wall of the side near the first mounting frame 9. A second telescopic rod 21 is fixedly mounted on the inner wall of the top of the second mounting frame 10. A frame 16 is fixedly mounted at the end of the second telescopic rod 21. A second conveyor belt 20 is provided inside the frame 16. A pressing assembly is provided on the side of the frame 16 away from the first mounting frame 9. The pressing assembly includes a second mounting plate 17 fixedly mounted on the side of the frame 16 away from the first mounting frame 9.

The ends of the two first telescopic rods 18 are fixedly connected to the top of the pressing plate 19. Before the equipment cuts the paper, the pressing plate 19 is driven down by the first telescopic rods 18 to contact the top of the paper, which can press and fix the paper, which helps to maintain the stability of the paper during subsequent cutting.

[0043] The second mounting frame 10 is equipped with a cutting component, which includes a cutter 15 disposed within the second mounting frame 10. A third cylinder 14 is fixedly mounted on the top of the second mounting frame 10. The piston shaft of the third cylinder 14 slides through the second mounting frame 10, and the end of the piston shaft of the third cylinder 14 is fixedly connected to the top of the cutter 15. A groove 11 is provided on the top of the base 1, and a first conveyor belt 12 is disposed within the groove 11. After the paper is fixed, the cutter 15 is driven to descend by the third cylinder 14. The cutter 15 contacts the paper under the acceleration of the third cylinder 14, thus performing the cutting function. The cut paper moves onto the first conveyor belt 12 under the pushing force of subsequent paper, and is then conveyed away by the first conveyor belt 12.

[0044] The implementation principle of this utility model embodiment is as follows: When using the equipment, the operator places the unwinding rod 8, which is wrapped with paper jam, on top of the two first mounting plates 2, so that the unwinding rod 8 engages with the placement slots 33 opened on the top of the two first mounting plates 2. The side wall of the unwinding rod 8 is provided with a limiting plate, which not only restricts the paper jam, but also the opposite side of the two limiting plates is attached to the inner side of the first mounting plate 2 on the same side, which restricts and positions the unwinding rod 8. After the unwinding rod 8 is placed, the operator assembles the drive component with the opposite end of the unwinding rod 8. Then, the operator pulls the paper jam end through the third support rod 25, tension adjustment component, second support rod 23, first support rod 22 and second conveyor belt 20 in sequence. The drive component drives the unwinding rod 8 to rotate, which can play the role of unwinding the paper jam. The second telescopic rod 21 drives the frame 16 and the second conveyor belt 20 to descend, so that the second conveyor belt 20 The second conveyor belt 20, which contacts the top of the cardboard, has wear-resistant protrusions on its surface. These protrusions increase the friction between the second conveyor belt 20 and the cardboard, facilitating the movement of the second conveyor belt 20 and thus pulling the cardboard along. Once the cardboard has moved the corresponding length, it is fixed by a pressing component. The cardboard is then cut by a cutting component. The cut cardboard moves onto the first conveyor belt 12 under the pushing force of subsequent cardboard. The cut cardboard is then conveyed away by the first conveyor belt 12. A tension adjustment component is located between the two third support rods 25. The tension adjustment component is raised and lowered by a second cylinder 13, which in turn pushes the cardboard downwards and deforms it. With the cooperation of the two third support rods 25, the tension of the cardboard is adjusted during transport, which helps maintain the tautness of the cardboard and prevents wrinkles from forming during transport.

[0045] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
