Description

Technical Field

[0001] The utility model relates to the technical field of die cutting, in particular to a die cutting plate with an anti-slip hard template. Background Art

[0002] After completing the entire printing process on the surface of the paper material, the die-cutting plate will die-cut the paper according to the predetermined box die-cutting line, remove the excess part of the paper, and stack the die-cut paper products into stacks in sequence before sending them out.

[0003] Traditional die-cutting plates use a number of rows of columnar modified elastic sponges to wrap or enclose the die-cutting knife in conjunction with elastic pressure columns, using their elastic deformation to press the paper and prevent it from shifting. In actual use, since the modified sponge has a relatively low pressing force on the paper and the elastic pressure column has a relatively high pressing force on the paper, an elastic pressure difference is generated. Therefore, when pressing the paper, the modified sponge can play the advantage of preventing the paper from being damaged by friction marks in the pressing area of ​​the paper, while the elastic pressure column can exert a tight pressing effect on the paper to keep the paper flat as a whole; but correspondingly, the weaker mechanical elastic strength also causes the modified sponge with a relatively low pressing force to be unable to provide sufficient pressing force for the paper at both ends of the die-cutting knife when it is cut by the die-cutting knife, and the flatness of the paper is easily reduced when it is under pressure from the die-cutting knife; and due to the difference in elasticity between the elastic pressure column and the modified elastic sponge, the elastic pressure column can also play a role in the paper's smoothness. If the position of the column and modified elastic sponge is not set properly, it is easy to cause uneven elastic pressure on the local area of ​​the paper, resulting in irregular burrs on the local edge after the paper is die-cut; especially when the elasticity of the modified elastic sponge decreases after long-term use, when processing heavier paper, or when the local sharpness of the die-cutting knife is relatively low, the probability of this situation is higher, and when the paper products after die-cutting are stacked into piles, these burr areas can be more clearly found; when the burr area occupies a large area and is located on the outer edge of the folded box, it is easy to be perceived by consumers and affect the overall appearance of the box and then affect the grade of packaging and decoration, to a certain extent reducing consumers' consumption desire and the brand reputation of the product. Summary of the Invention

[0004] The technical purpose of the utility model is to provide a die-cutting plate with a non-slip hard template, which can more stably reduce the generation of burrs on the edges of die-cut paper.

[0005] In order to achieve the above purpose, the present invention adopts the following technical means to implement:

[0006] A die-cutting plate with an anti-slip hard template includes a hard template and a die-cutting blade. The die-cutting blade is provided with a rubber piece. The strip-shaped rubber piece is arranged on both sides of the die-cutting knife at a distance along the length direction of the die-cutting knife. The rubber piece has at least one convergence section from the base side to the pressing side, and the blade of the die-cutting knife is lower than the top of the lower pressing surface of the two rubber pieces. The lower pressing surface of the rubber piece is vertically projected onto the area of ​​the hard template and is at least partially provided with an anti-slip area. The lower pressing surface is a pressing surface and / or a pressing side surface. The pressing side surface is a convex arc surface, and the pressing surface is a plane.

[0007] Furthermore, the pressed side surface is an arc surface with a central angle of 45°-135° in the cross section.

[0008] Furthermore, the pressing surface is a plane extending from the folded corner of the pressing side toward the die cutting knife.

[0009] Furthermore, the angle between the pressing surface and the hard template is 0°-5°.

[0010] Furthermore, the vertical projection area of ​​the anti-slip zone is not less than the pressing surface.

[0011] Furthermore, a recessed area is provided on the inner side surface of the rubber member close to the die cutter.

[0012] Furthermore, the recessed area is a strip-shaped concave arc surface or a strip-shaped concave angled surface extending from the head end to the tail end.

[0013] Furthermore, a strip-shaped transition arc surface is provided between the lower pressing surface and the inner side surface.

[0014] Furthermore, a gap space is provided at the base of the rubber component.

[0015] Furthermore, the gap space is a strip-shaped gap extending from the front end to the rear end of the rubber member, and the shape of the strip-shaped gap can be selected to have a cross-section in a triangular, fan-shaped, rectangular or other shape.

[0016] The utility model has at least the following benefits:

[0017] 1. By using rubber parts and anti-slip areas to press the paper together, the pressed paper can be fixed and flat, and the paper is not likely to slide inward due to the pressure of the die-cutting knife. Therefore, if the die-cutting knife is sharp enough, the generation of burrs on the edge of the die-cut paper can be more stably reduced;

[0018] 2. By optimizing the shape of the rubber parts, lateral friction can be provided for the pressed paper while maintaining a fixed and flat surface. The paper can be tensioned by the lateral friction between the two rubber parts, thereby maintaining a highly flat state and making it easier for the die cutter to cut. In addition, the reasonable selection and adjustment of the pressing surface and / or pressing side surface of the rubber parts to form the lower pressing surface, as well as the area of ​​the anti-slip area, can provide a micro-indentation glue attachment area for different paper materials, and an anti-indentation effect for paper that is prone to marking, with good versatility.

Example

[0033] like Figure 1-5 As shown, a die-cutting plate with a non-slip hard template includes a die-cutting blade 1 and a hard template 2. The die-cutting blade 1 is provided with a strip-shaped rubber member 11. The rubber member 11 extends from the head end to the tail end. Any cross-section perpendicular to this direction is the same trapezoid. The long side of the trapezoid of the cross-section of the rubber member 11 is located on the base side 13 and the short side of the trapezoid is located on the pressing side 14. That is, the rubber member 11 as a whole is in a converging shape from the base side 13 to the pressing side 14.

[0034] The two rubber members 11 are arranged on both sides of the die-cutting knife 12 apart along the length direction of the die-cutting knife 12. In this embodiment, the downward pressing surface of the rubber member 11 is arranged to be a 0° horizontal plane, the distance a1 between the inner lines of the downward pressing surface is 3.5 mm, and the distance a2 at which the blade of the die-cutting knife 12 is lower than the downward pressing surfaces of the two rubber members 11 is 1.5 mm.

[0035] The area where the lower pressing surface of the rubber member 11 is vertically projected onto the hard template 2 is provided with an anti-slip area 21. The anti-slip area 21 in this embodiment adopts a dense mesh texture engraved by internal milling. Its shape matches the edge of the paper and has a width of 5-7mm. When the paper is pressed by the hard template 2 and the rubber member 11, the mesh texture presses one side of the inner surface of the paper, and the lower pressing surface of the rubber member 11 as the pressing surface 101 presses the side of the coated printing surface of the paper. Therefore, when the paper is pressed, the surface material of the printed surface is not damaged, and the paper can be prevented from slipping. In the process of the paper being pressed by the hard template 2 and the rubber member 11 until the die cutter 12 cuts the paper, the cut area of ​​the paper is cut by the rubber member. The compression deformation of 11 makes the paper material fully pressed and kept flat, and the paper material is not easy to slide inward due to the pressure of the die-cutting knife 12. Therefore, when the die-cutting knife 12 is sharp enough, the generation of burrs on the edge of the die-cut paper material can be more stably reduced; when the die-cutting plate is reset, the rubber member 11 maintains the pressure on the paper material during the reset process from the elastic compression state until the pressing surface 101 is separated from the paper material. At this time, the paper material is completed and cut. The process reduces the burrs on the die-cutting edge of the paper material caused by insufficient elastic pressing force of the modified elastic sponge at both ends of the die-cutting knife 12, or possible elastic pressure columns, elastic differences of the modified elastic sponge, etc.

[0036] In addition, by properly controlling the elasticity of the rubber member 11, the rubber member 11 can be deformed under pressure to press the paper, thereby forming fine marks on the inner surface of the paper by pressing the mesh texture. The fine marks on the inner surface of the paper can further increase the coating area of ​​the glue and improve the adhesion.

[0037] Of course, the shape of the inner milling carving is not limited to the mesh texture, and regular or irregular curves, frosted textures, regular concentric shapes, etc. can also be used. In addition to the inner milling carving method, the anti-slip area 21 can also use other hard materials with anti-slip functions or pressure-sensitive micro-deformable materials, which are installed in the corresponding vertical projection area of ​​the hard template 2 to prevent the paper from slipping when it is under pressure. Example

[0038] like Figure 1-3As shown in Figures 6 and 7, based on Example 1, this embodiment changes the shape of the rubber member 11 so that the rubber member 11 extends from the head end to the tail end, and any cross-section perpendicular to this direction is the same. The base is trapezoidal as a whole and the pressing portion is fan-shaped as a whole. A recessed area 15 is provided on the inner side surface between the base and the pressing portion near the die cutter 12. The recessed area 15 is a strip-shaped concave angled surface extending from the head end to the tail end, so that the recessed area 15 is an angled transition section connecting the base and the pressing portion in the cross section; more specifically, the base is provided with two strip-shaped notches 16 extending from the head end to the tail end of the rubber member 11. The cross section of the strip notches 16 is two triangles at the base position. The outer side surface of the pressing portion is a convex arc surface with a cross-sectional central angle b3 of 110°. The convex arc surface is the pressing side surface. The rubber member 11 is overall gathered from the base side to the pressing side to the end H2 of the transition section.

[0039] The two rubber members 11 are separated along the length direction of the die-cutting knife 12 and are detachably mounted on both sides of the die-cutting knife 12. In this embodiment, the downward pressing surface of the rubber member 11 is the pressing side surface, the distance b1 between the inner edges of the downward pressing surface is 3 mm, and the distance b2 at which the blade of the die-cutting knife 12 is lower than the downward pressing surfaces of the two rubber members 11 is 1.25 mm.

[0040] The anti-slip area 21 in this embodiment also features a densely milled mesh texture. Its area lies between the vertical projection of the rubber member 11's lower pressing surface onto the rigid template 2 and the contact surface between the lower pressing surface and the rigid template 2 at the die-cutting plate's maximum pressing stroke. This arrangement ensures that even at the die-cutting plate's maximum pressing stroke, the lower pressing surface and anti-slip area 21 still provide sufficient anti-slip pressure for the pressed paper.

[0041] In the process of the paper being pressed by the hard template 2 and the rubber member 11 until the die-cutting knife 12 cuts the paper, the cut area of ​​the entire paper is pressed by multiple groups of rubber members 11, and the anti-slip area 21 presses on one side of the inner surface of the paper, so that when each rubber member 11 is deformed under pressure, the paper does not slide due to the deformation of the pressed side, and the paper can be fully compressed; at the same time, since the rubber member 11 is arranged in a whole-shaped manner from the base side to the pressed side to the end H2 of the transition section, when the knife template moves toward the hard template 2, the force on the inner side of the rubber member 11 is relatively greater than the outer side of the rubber member 11, so the elastic restoring force on the inner side of the rubber member 11 is greater than the outer side of the rubber member 11, which is reflected in the die-cutting process on a macro scale. The rubber members 11 on both sides of the knife 12 provide a separating frictional force on the paper. At this time, the paper is tensioned and maintained in a highly flat state due to the separation friction of the two rubber members 11. Therefore, when the die-cutting knife 12 has the same sharpness, compared with the solution of Example 1, it is easier to complete the cutting of the paper and more effectively reduce the generation of burrs on the edges of the die-cut paper. When the die-cutting plate is reset, the rubber member 11 maintains the pressure on the paper during the reset process from the elastic compression state, and due to the separation friction traction of the two rubber members 11, the paper is separated from the pressing surface 101. The two sides of the paper that have completed the die-cutting are separated by the traction force of the two rubber members 11.

[0042] In addition, by providing the strip-shaped notches 16, the elasticity of local areas of rubber materials with relatively high hardness can be reduced, thereby enabling the elasticity of the rubber member 11 to be specifically controlled within a reasonable range, enabling the rubber member 11 to be deformed under pressure to press the paper material without excessive deformation due to the low elastic strength of the rubber member 11 material. This is particularly suitable for rubber members 11 with convex curved surfaces for pressing the side surfaces. The cross-sectional shape of the strip-shaped notches 16 is not limited to the triangle in this embodiment, but can also adopt shapes such as fan-shaped, rectangular, and semicircular. The extension direction of the strip-shaped notches 16 is not limited to straight strip-shaped notches 16, but can also adopt a mesh arrangement composed of multiple straight strip-shaped notches 16 extending obliquely, or a curved strip-shaped notch 16 extending in a zigzag manner from the head end to the tail end of the rubber member 11, so as to reasonably adjust the rubber member 11 to have reasonable elastic deformation performance. Example

[0043] like Figure 1-3, 8, and 9, this embodiment, based on Example 1, changes the shape of the rubber member 11 so that it is in the extending direction of the rubber member 11 from the head end to the end, and any cross section perpendicular to the direction is of the same shape. Specifically, the base is provided with a plurality of strip-shaped notches 16 arranged alternately and extending from the head end to the end of the rubber member 11, the lower pressing surface is a plane with an angle c4 of 2° between the pressing surface 101 and the hard template 2, and the pressing side surface 102 is a cross-sectional central angle c3 of The rubber member 11 has a 60° convex arc surface, and the pressing surface 101 extends from the pressing side surface 102 to the die-cutting knife 12 in an angled manner. The outer side surface of the rubber member 11 away from the die-cutting knife 12 is a strip-shaped convex arc surface. The inner side surface of the rubber member 11 close to the die-cutting knife 12 is provided with a recessed area 15 with a strip-shaped concave arc surface. A strip-shaped transition arc surface 17 is provided between the pressing surface 101 and the recessed area 15. The rubber member 11 is in a gathered shape as a whole in the area H3 connecting the most convex outer side surface and the most concave inner side surface from the base side to the pressing side.

[0044] The two rubber members 11 are arranged on both sides of the die-cutting blade 12, spaced apart from each other along the length direction of the die-cutting blade 12. In this embodiment, the lower pressing surface of the rubber member 11 is a pressing surface 101 and a pressing side surface 102. The top of the lower pressing surface is located at the inner edge of the pressing surface 101 on the side close to the die-cutting blade 12. The distance c1 between the inner edges of the pressing surface 101 is 3.2 mm. The distance c2 between the blade edge of the die-cutting blade 12 and the lower pressing surfaces of the two rubber members 11 is 1 mm.

[0045] The anti-slip area 21 in this embodiment also uses a dense mesh texture engraved by internal milling. The area of ​​the anti-slip area 21 is equal to the area of ​​the lower pressing surface vertically projected onto the hard template 2. Through this arrangement, when the die-cutting plate is at its maximum pressing stroke, the lower pressing surface and the anti-slip area 21 can provide sufficient anti-slip pressing effect for the pressed paper.

[0046] In the process of the paper being pressed by the hard template 2 and the rubber member 11 until the die-cutting knife 12 cuts the paper, the cut area of ​​the entire sheet of paper is pressed by multiple groups of rubber members 11, and the anti-slip area 21 presses on one side of the inner surface of the paper, so that when each rubber member 11 is deformed under pressure, the paper will not slide due to the deformation of the pressed side surface 102, and the paper can be fully compressed; similarly, when the knife template moves toward the hard template 2, the force on the inner side of the rubber member 11 is relatively greater than the outer side of the rubber member 11, so the elastic restoring force on the inner side of the rubber member 11 is greater than the outer side of the rubber member 11. Macroscopically, the paper is tensioned and kept highly flat due to the friction between the two rubber members 11, so the generation of burrs on the edge of the die-cut paper can also be effectively reduced during die-cutting; at the same time, this embodiment is different from the embodiment 2 in that it is different from the embodiment 2 in that it is different from the embodiment 2 in that it is different from the embodiment 2 In the scheme, due to the plane with an angle of 2° between the pressing surface 101 and the hard template 2, at the position where the entire lower pressing surface presses the paper, the smaller pressing area near the inner edge of the pressing surface 101 can exert a higher pressing force on the paper, and the outer area of ​​the pressing surface 101 near the pressing side surface 102 has a relatively high pressing force on the paper, and the pressing force on the paper at the pressing side surface 102 is relatively low compared to the pressing force on the paper at the pressing surface 101. This scheme is more suitable for die-cutting of paper that is prone to indentation. It can prevent the paper from being subjected to excessive pressure, so that such paper is subjected to more sufficient tension during die-cutting, thereby reducing the generation of edge burrs during die-cutting, and prevent the large area of ​​excessively deep indentations caused by the clamping of such paper by the larger area of ​​the lower pressing surface pressing area and the milled carved texture on the anti-slip surface.

[0047] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
