Description

Technical Field

[0001] The utility model relates to the technical field of packaging box production tools, in particular to a packaging box die-cutting die. Background Art

[0002] Rigid packaging boxes are generally made of hard gray board and colored paper. The die cutter on the die-cutting machine cuts the gray board into a preset shape, then pastes the gray board on the pre-printed colored paper, and finally folds it into the shape of the packaging box. In order to print the anti-counterfeiting mark on the box body, concave patterns are generally pre-printed on both the gray board and the colored paper to give the surface of the packaging box a concave and convex touch. The positions of the concave patterns on the two must correspond, otherwise it will be a substandard product.

[0003] The prior art prints the concave patterns on the grey board by two processes, namely cutting and embossing. Not only is the production efficiency low, but also during embossing, the relative positions of the embossing mold and the grey board are not completely fixed. The embossing mold or the grey board may shift, causing the concave patterns to shift, which in turn causes the concave patterns on the grey board and the colored surface paper to not correspond, thereby reducing the qualified rate of finished products. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a packaging box die-cutting die, which solves the problem in the prior art that printing grey plate concave patterns will reduce production efficiency and finished product qualification rate.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] Provided is a packaging box die-cutting die, comprising a die-cutting plate and a cutter assembly fixed on the die-cutting plate, a stamping plate with embossed convex patterns on the surface is arranged in the area enclosed by the cutter assembly, and the stamping plate is detachably connected to the die-cutting plate.

[0007] The beneficial effects of the utility model are as follows: in this scheme, a cutter assembly and a pressing plate for pressing concave patterns are simultaneously arranged on the die-cutting plate; when working, the die-cutting plate drives the cutter assembly to press downward, so that the gray board is cut into a preset shape; the pressing plate can press concave patterns onto the gray board while cutting the gray board, thereby reducing the production process and improving the production efficiency.

[0008] Since the relative positions of the stamping plate and the cutter assembly are fixed, even if the gray board to be cut is slightly offset when placed, the relative positions of the cut gray board and the concave pattern will always correspond, and the concave pattern will not be offset, thereby improving the qualified rate of finished products.

[0009] Furthermore, a back plate is connected to the side of the embossing plate away from the embossed relief, and the back plate is detachably connected to the die cutting plate. The embossing plate is not directly connected to the die cutting plate but is connected to the die cutting plate through the back plate. When the embossing plate needs to be replaced, the back plate can be removed.

[0010] Furthermore, the die-cutting plate is provided with a mounting hole passing through it, and a step groove is provided near the mounting hole; a support block is fixedly connected to the back plate; the embossing plate and the back plate are both embedded in the mounting hole, and the support block is supported on the bottom surface of the step groove; the embossing plate is embedded in the mounting hole, and the embossed convex pattern protrudes from the lower surface of the die-cutting plate.

[0011] The above technical solution has the beneficial effect that the back plate can be directly taken out from the mounting hole without any auxiliary tools, which facilitates the rapid replacement of the stamping plate. When the die cutter moves downward for die cutting, the step groove blocks the back plate from falling off the die cutting plate under pressure.

[0012] Furthermore, the cross-sectional shape of the back plate and the cross-sectional shape of the mounting hole are the same as the cross-sectional shape of the stamping plate. The mounting hole and the back plate have the same cross-sectional shape, so that the two can fit closely together, so that the mounting hole can limit the left and right positions of the back plate.

[0013] Furthermore, the support block and the back plate are integrally formed, and the upper surfaces of the support block, the back plate and the die-cutting plate are located on the same horizontal plane, thereby ensuring the flatness of the die-cutting plate when connected with other components.

[0014] Furthermore, elastic pads are arranged on both sides of the cutter assembly, and the elastic pads are fixedly connected to the die-cutting plate. The elastic pads can protect the cutter assembly.

[0015] Furthermore, the stamping plate is fixed to the back plate by means of cup head screws, the heads of the cup head screws do not exceed the lower surface of the stamping plate, and the tails of the cup head screws do not exceed the upper surface of the back plate.

[0016] Furthermore, the embossing plate and the back plate are both provided with connecting grooves, the head of the cup head screw is embedded in the connecting groove of the embossing plate, and the nut is embedded in the connecting groove of the back plate.

[0017] Furthermore, at least two positioning holes are formed on the stamping plate and the back plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The specific implementation methods of the utility model are described below to facilitate technical personnel in this technical field to understand the utility model, but it should be clear that the utility model is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the utility model are protected.

[0023] like Figure 1 As shown, the packaging box die-cutting die 1 of the present scheme includes a die-cutting plate 12 and a cutter assembly 11 fixed on the die-cutting plate 12, and a stamping plate 2 with an embossed convex pattern 21 on the surface is arranged in the area enclosed by the cutter assembly 11, and the stamping plate 2 is detachably connected to the die-cutting plate 12.

[0024] In this solution, a cutter assembly 11 and a stamping plate 2 for pressing concave patterns are simultaneously arranged on the die-cutting plate 12. During operation, the die-cutting plate 12 drives the cutter assembly 11 to press downward, so that the gray board is cut into a preset shape. The stamping plate 2 can press concave patterns onto the gray board while cutting the gray board, thereby reducing production processes and improving production efficiency.

[0025] Since the relative positions of the stamping plate 2 and the cutter assembly 11 are fixed, even if the gray board to be cut is slightly offset when placed, the relative positions of the cut gray board and the concave patterns will always correspond, and the concave patterns will not be offset, thereby improving the qualified rate of finished products.

[0026] The reason why the embossing plate 2 and the die-cutting plate 12 are detachably connected in this solution is that the embossing plate 2 is a vulnerable part. After embossing a certain number of cardboards, the embossed convex pattern 21 on its surface will be damaged and needs to be replaced regularly. This can avoid replacing the entire die-cutting plate 12 when replacing the embossing plate 2.

[0027] refer to Figure 2 The side of the embossing plate 2 away from the embossed convex pattern 21 is connected with a back plate 25, and the back plate 25 is detachably connected to the die cutting plate 12. The embossing plate 2 is not directly fixed to the die cutting plate 12, but is connected to the die cutting plate 12 through the back plate 25. When the embossing plate 2 is replaced, the back plate 25 can be removed.

[0028] refer to Figure 3 The die-cutting plate 12 is provided with a mounting hole 123 passing through it, and a step groove 124 is provided near the mounting hole 123. A support block 125 is fixedly connected to the back plate 25; the embossing plate 2 and the back plate 25 are both embedded in the mounting hole 123, and the support block 125 is supported on the bottom surface of the step groove 124; the embossed convex pattern 21 protrudes from the lower surface of the die-cutting plate 12. The upper surface of the die-cutting plate 12 refers to Figure 2 The lower surface is the plane shown in Figure 1 The plane shown in .

[0029] Since the cutting die 1 needs to be bolted to the power mechanism when in use, specifically, the upper plane of the die-cutting plate 12 is bolted to the mounting plate of the power mechanism, the back plate 25 will also abut against the mounting plate, thereby limiting the upward displacement of the back plate 25, and the step groove 124 can limit the downward displacement of the back plate 25 to prevent it from falling.

[0030] When the platen 2 needs to be replaced, the die-cutting plate 12 is first separated from the power mechanism. After separation, the back plate 25 can be directly taken out from the mounting hole 123 without any auxiliary tools, which facilitates the rapid replacement of the platen 2.

[0031] In implementation, the cross-sectional shapes of the back plate 25 and the mounting hole 123 are the same as the cross-sectional shape of the embossing plate 2. Since the cross-sectional shapes of the back plate 25 and the mounting hole 123 are the same, after the back plate 25 is inserted into the mounting hole 123, the side wall of the back plate 25 can be in close contact with the inner wall of the mounting hole 123, and the mounting hole 123 can limit the back plate 25 to the left and right to prevent the back plate 25 from shaking to the left and right, which affects the quality of the embossed concave pattern.

[0032] Preferably, the support block 125 and the back plate 25 are integrally formed, and the upper surfaces of the support block 125, the back plate 25, and the die-cutting board 12 are located at the same horizontal plane. The support block 125, the back plate 25, and the die-cutting board 12 are located at the same horizontal plane to facilitate a smooth connection with the mounting plate of the power mechanism.

[0033] The cutter assembly 11 includes a plurality of blades, and there is a gap between two adjacent blades. After the shearing is completed, the gray board is not completely cut off in this solution, but a certain connection part is left on the gray board to disperse the stress and reduce the phenomenon of the gray board warping.

[0034] refer to Figure 1 , elastic pads 3 are provided on both sides of the cutter assembly 11, and the elastic pads 3 are fixedly connected to the die-cutting plate 12. During transportation, the elastic pads 3 can protect the cutter assembly 11. Secondly, during die-cutting, the elastic pads 3 can be quickly compressed to expose the cutter assembly 11, thereby ensuring normal die-cutting.

[0035] The stamping plate 2 is fixed to the back plate 25 by means of a cup head screw 24, the head of the cup head screw 24 does not extend beyond the lower surface of the stamping plate 2, and the tail of the cup head screw 24 does not extend beyond the upper surface of the back plate 25. The head of the cup head screw 24 does not extend beyond the lower surface of the stamping plate 2, which can prevent the cup head screw 24 from contacting the gray plate first, pressing out the mark of the cup head screw head, or even damaging the gray plate. The nut does not extend beyond the upper surface of the back plate 25, which can prevent the die-cutting plate 12 from being unable to be installed due to the protruding nut when it is connected to the power mechanism.

[0036] Specifically, the embossing plate 2 and the back plate 25 are both provided with connecting grooves, the head of the cup head screw 24 is embedded in the connecting groove of the embossing plate 2, and the nut is embedded in the connecting groove of the back plate 25. The connecting groove has a groove bottom, and a through hole for the cup head screw 24 to pass through is provided at the groove bottom. The groove hole of the connecting groove can accommodate the cup head screw 24, and the groove bottom of the connecting groove can provide a connecting surface for the head of the cup head screw 24 and the nut to play a connecting role.

[0037] Preferably, at least two positioning holes 22 are provided on the platen 2 and the back plate 25. When fixing the platen 2 and the back plate 25, in order to ensure the accuracy of the positioning of the platen 2, the positioning piece is first inserted into the positioning hole 22, and then the cup head screw 24 is fixed. The positioning piece can be a positioning rod with a magnetic head, the platen 2 can be an iron product, and the magnetic head of the positioning rod is magnetically attracted to the platen 2. After all the cup head screws 24 are installed, the positioning piece can be removed.

[0038] In summary, this solution can press grooves into the grey board while cutting the grey board by detachably connecting the stamping plate 2 to the cutting die 1, thereby improving production efficiency and ensuring that the relative positions of the grey board and the grooves after cutting always correspond, thereby improving the qualified rate of finished products.
