Description

Technical Field

[0001] The utility model relates to the field of carton production equipment, in particular to a disassembly and assembly structure of a knife die. Background Art

[0002] In modern society, with the booming development of e-commerce and the rapid expansion of the logistics industry, cartons of various sizes and shapes have become a core demand in the packaging industry. The carton production process involves several key steps, among which die-cutting is a crucial step in achieving the desired size and shape of cartons. Die-cutting is typically performed using a die-cutter, whose core working component is the die plate. The die plate is a mold that forms a cutting tool into the desired shape and is then fixed to the die plate. When the die-cutter is in use, the die plate is mounted on the die-cutter's roller. Cardboard is then fed into the die-cutter, where the roller, equipped with the die, rotates over the cardboard, cutting it to the desired size and shape.

[0003] However, the existing cutting die plate and the roller are mostly fixed by screw connection. This connection structure can ensure the stability of the connection between the cutting die plate and the roller, but because the screw connection positions and numbers required for cutting dies of different sizes are different, this connection structure cannot be applied to the disassembly and assembly of rollers and different cutting dies. As a result, when producing cartons of different sizes and shapes, the cutting die and the roller need to be disassembled and replaced together from the die-cutting machine, which increases production costs.

[0012] The positioning plate includes a sliding portion and a positioning portion. One end of the sliding portion is fixedly connected to the positioning portion, and the other end and the sliding seat are both slidably arranged in the sliding groove. The positioning portion and the sliding seat are respectively located on both sides of the convex strip;

[0013] The connecting piece passes through the sliding portion and the positioning portion and is screwed to the sliding seat;

[0014] When the connecting member rotates, the sliding seat and the positioning plate are driven to move relative to each other along the radial direction of the roller, so that the sliding seat and the positioning portion clamp the convex strip.

[0015] It is further provided that the aforementioned slide is provided with a clearance groove for inserting the sliding part; in the depth direction of the slide groove, there is a movable gap between the slide and the slide groove, so that the slide and the positioning plate can be relatively displaced along the radial direction of the roller, and the sum of the sizes of the convex strip and the clearance groove is greater than the size of the sliding part, so that when the slide and the positioning plate are relatively displaced along the radial direction of the roller, the slide and the positioning part can respectively press against the two sides of the convex strip to clamp the convex strip.

[0016] It is further provided that the aforementioned sliding portion is provided with a sliding recess, and the convex strip is located in the sliding recess so that the sliding portion is slidingly connected to the slide groove of the roller; in the depth direction of the slide groove, the size of the convex strip is smaller than the size of the sliding recess.

[0017] It is further provided that a threaded hole is provided on the aforementioned sliding seat, and the connecting member includes a fixed handle and a threaded rod, and the threaded rod is threadedly matched with the threaded hole.

[0018] It is further provided that the aforementioned positioning plate includes a reinforcement plate, and two slots are symmetrically provided on both sides of the knife plate.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The utility model provides a disassembly structure of a cutting die, which is used for detachably connecting a roller 1 and a cutting die plate 2, and solves the problem of how to be applicable to disassembly of the roller 1 and cutting dies of different sizes.

[0036] See Figure 1 As shown, Figure 1 3D is a three-dimensional diagram of the disassembly and assembly structure of the cutting die in the embodiment, which includes a slide 3, a positioning plate 4, an insertion rod 5 and a connecting piece 6.

[0037] There are two slides 3 and two positioning plates 4, each of which is slidably connected to the roller 1 along the axial direction of the roller 1. The roller 1 includes a protrusion 12, with the slide 3 and the positioning plates 4 located on either side of the protrusion 12. A clamping space 7 is formed between the two positioning plates 4 for positioning the cutting plate 2.

[0038] The insertion rod 5 is arranged on the positioning plate 4 by integral connection, welding or screw connection, and the insertion rod 5 is completely or partially located in the clamping space 7. There are at least two sockets 21 on both sides of the knife template 2. The positions of the insertion rod 5 and the sockets 21 correspond one to one and are plugged in.

[0039] The connecting member 6 is connected to the slide 3 and the positioning plate 4 respectively, so that the slide 3 and the positioning plate 4 clamp the convex strip 12, thereby fixing the slide 3, the positioning plate 4 and the roller 1.

[0040] When installing the cutting die of the disassembling structure of the above technical solution, first put the cutting die plate 2 into the clamping space 7, then slide the slide 3 and the positioning plate 4 to drive the insertion rod 5 to be inserted into the corresponding socket 21, so that the insertion rod 5 abuts against the bottom of the socket 21, or the positioning plate 4 abuts against the side of the cutting die plate 2, thereby clamping the cutting die plate 2 in the clamping space 7, and finally, through the connecting piece 6, the slide 3 and the positioning plate 4 clamp the convex strip 12 to fix the position of the slide 3 and the positioning plate 4 on the roller 1, thereby achieving fixed installation of the cutting die plate 2 on the roller 1; when disassembling the cutting die of the disassembling structure, the slide 3 and the positioning plate 4 are loosened by the connecting piece 6, and then the slide 3 and the positioning plate 4 are slid, and the insertion rod 5 is moved out of the socket 21 to remove the cutting die plate 2 from the clamping space 7, thereby achieving removal of the cutting die plate 2 from the roller 1. As can be seen, this die-cutting assembly and disassembly structure is suitable for disassembling and assembling the roller 1 and die-cutting dies of different sizes. Compared with the existing connection structure between the die-cutting dies and the roller 1, this die-cutting assembly and disassembly structure only requires disassembling and replacing the die-cutting dies of different sizes when producing cartons of different sizes and shapes, without having to replace the roller 1, which greatly reduces production costs. In addition, this die-cutting assembly and disassembly structure can also steplessly adjust the axial position of the die-cutting plate 2 on the roller 1 by adjusting the position of the sliding slide 3 and the positioning plate 4 on the roller 1.

[0041] The jacks 21 on the same side of the cutting plate 2 are spaced apart, and the more jacks 21 and insertion rods 5 there are, the larger the connection area between the cutting plate 2 and the roller 1 is, and the more stable the connection structure between the cutting plate 2 and the roller 1 is.

[0042] The positioning plate 4 can be connected to the slide 3 via a connecting member 6 , thereby being slidably connected to the roller 1 . The positioning plate 4 can also be directly slidably connected to the roller 1 .

[0043] See Figure 1 and Figure 2 As shown, Figure 2The figure is a cross-sectional view of the slide 3, the positioning plate 4, and the connector 6 along the radial direction of the roller 1. In one embodiment in which the connector 6 is connected to the slide 3 and the positioning plate 4, a groove 11 is formed on the outer peripheral wall of the roller 1. The groove 11 extends along the axial direction of the roller 1. The groove 11 has symmetrically distributed protrusions 12 on both sides of the groove wall. The protrusions 12 extend along the extension direction of the groove 11. The positioning plate 4 includes a sliding portion 41 and a positioning portion 42. One end of the sliding portion 41 is fixedly connected to the positioning portion 42 by integral connection or welding, and the other end is slidably connected to the slide 3 in the groove 11. The positioning portion 42 and the slide 3 are respectively located on both sides of the protrusion 12. The connector 6 passes through the sliding portion 41 and the positioning portion 42 and is screwed to the slide 3. When the connector 6 rotates, it drives the slide 3 and the positioning plate 4 to move relative to each other along the radial direction of the roller 1, so that the slide 3 and the positioning portion 42 clamp the protrusion 12. In this way, the disassembly structure of the cutting die can clamp or loosen the convex strip 12 by tightening or loosening the connecting piece 6, thereby realizing the assembly and disassembly of the cutting die and the roller 1. The disassembly method is simple and easy to operate, and it is convenient and quick to disassemble the cutting die and the roller 1; and the positioning plate 4 is directly slidably connected to the outer wall of the roller 1 through the sliding part 41, which can also prevent the positioning plate 4 from accidentally detaching from the roller 1, resulting in damage or loss of the positioning plate 4.

[0044] The two slides 3 and the positioning plate 4 are slidably connected in the same slide groove 11 . The slide groove 11 can limit the two slides 3 and the positioning plate 4 to move toward or away from each other along the same straight line, so as to adjust the size and position of the clamping space 7 .

[0045] One of the slide 3 and the positioning plate 4 can always be in contact with one side of the ridge 12, while the other is driven by the connecting member 6 to move along the radial direction of the roller 1 toward the other side of the ridge 12, so that the slide 3 and the positioning plate 4 are relatively displaced to clamp the ridge 12. Alternatively, both the slide 3 and the positioning plate 4 can be driven by the connecting member 6 to relatively displace along the radial direction of the roller 1 to clamp the ridge 12.

[0046] See Figure 2 As shown, based on the above embodiment, the slide 3 has a clearance groove 31 for inserting the sliding portion 41. A movable gap 8 is provided between the slide 3 and the slide 11 in the depth direction of the slide 11, allowing the slide 3 and the positioning plate 4 to move relative to each other in the radial direction of the roller 1. The sum of the dimensions of the ridge 12 and the clearance groove 31 is greater than the dimensions of the sliding portion 41. This allows the slide 3 and the positioning portion 42 to abut against both sides of the ridge 12 to clamp the ridge 12 when the slide 3 and the positioning plate 4 move relative to each other in the radial direction of the roller 1. In this way, the slide 3 can move radially along the roller 1 through the movable gap 8, and the positioning portion 42 can also move radially along the roller 1 through the clearance groove 31 without interfering with the slide 3. The relative displacement of the two along the radial direction of the roller 1 can achieve the clamping or release of the ridge 12.

[0047] The cam 32 is not loosened when the cam 32 is loosened and the cam 32 is not loosened until the cam 32 is loosened and the cam 32 is loosed.

[0048] See Figure 2 As shown, the sliding portion 41 is slidably disposed within the chute 11. The sliding portion 41 has a sliding recess 411, and the protrusion 12 is located within the sliding recess 411, so that the sliding portion 41 is slidably connected to the chute 11 of the roller 1. In the depth direction of the chute 11, the protrusion 12 is smaller than the size of the sliding recess 411. Thus, the sliding portion 41 is slidably connected to the protrusion 12 of the roller 1 via the sliding recess 411, thereby achieving a sliding position within the chute 11. The smaller size of the protrusion 12 than the size of the sliding recess 411 facilitates smooth sliding of the positioning plate 4 along the chute 11.

[0049] See Figure 1 and Figure 2 As shown, the connecting member 6 is screwed to the slide 3, and the slide 3 has a threaded hole 32. The connecting member 6 includes a handle 61 and a threaded rod 62 fixedly connected by integral connection or welding. The threaded rod 62 is threadedly engaged with the threaded hole 32. In this way, the handle 61 can be used to easily apply force to rotate the threaded rod 62 relative to the slide 3, thereby facilitating the disassembly of the die cutter and the roller 1.

[0050] See Figure 1 and Figure 3 As shown, Figure 3 This is a cross-sectional view of the slide 3, positioning plate 4, and connector 6 along the axial direction of the roller 1. In one embodiment of the positioning plate 4, the positioning plate 4 includes a reinforcement plate 43. Two slots 22 are symmetrically provided on either side of the cutting plate 2. When the insertion rod 5 is plugged into the insertion hole 21, the reinforcement plate 43 contacts and abuts against the side wall of the slot 22 near the roller 1. In this way, the reinforcement plate 43 can assist the positioning plate 4 and the insertion rod 5 in clamping the cutting plate 2 and the roller 1, increasing the connection area between the cutting plate 2 and the roller 1. At the same time, it applies a force to the cutting plate 2 toward the roller 1, thereby further improving the stability of the connection structure between the cutting plate 2 and the roller 1.

[0051] See Figure 3 As shown, based on the above embodiment, the slot 22 has an inclined wall on the side closest to the roller 1, extending obliquely toward the center of the cutting plate 2 and the outside of the roller 1. Thus, the reinforcement plate 43 and the slot 22 are wedge-fitted together. The deeper the reinforcement plate 43 penetrates into the slot 22, the more it can drive the cutting plate 2 toward the roller 1, making the connection between the cutting plate 2 and the roller 1 tighter and improving the stability of the connection between the cutting plate 2 and the roller 1.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
