Description
Technical Field
[0001] This application relates to the field of die-cutting blades for rotary die-cutting machines, and in particular to a highly adaptable tooling for pressing cardboard. Background Technology
[0002] Die-cutting is a common paperboard processing technology that can quickly create complex shapes on paperboard and other products. A rotary die-cutting machine is a high-efficiency cutting device that uses a continuous rotating roller structure. It is mainly used for large-scale die-cutting of materials such as paperboard. Its core consists of a molding roller and a pressure roller, which clamp the die-cutting to complete the process. It has two working modes: hard cutting and soft cutting. Due to the complexity and high cost of die-cutting plate production, this type of machine is more suitable for long-term and stable mass production needs and is often linked with printing machinery to form an automated production line.
[0003] However, in the existing rotary die-cutting machines, it is found that before die-cutting, the die-cutting blade needs to be installed on the substrate, and then the substrate and the die-cutting blade are installed on the surface of the die-cutting roller. When different sizes of products need to be die-cut, the die-cutting plate needs to be removed and replaced with a new die-cutting plate in order to process the new products. Therefore, it is not convenient to adjust the die-cutting blade, resulting in low applicability of the die-cutting plate. Utility Model Content
[0004] The purpose of this application is to provide a highly adaptable tooling for pressing cardboard, which has the advantages of being able to adjust the position of the die-cutting blade to change the size of the processed product and improve the applicability of the device, thus solving the problems mentioned in the background art.
[0005] This application provides a highly adaptable tooling for pressurizing cardboard, employing the following technical solution: It includes a substrate, the outer surface of which is provided with equidistantly arranged adjustment grooves; the inner wall of the substrate is rotatably connected to equidistantly arranged adjustment screws; the end of each adjustment screw is fixedly connected to a worm gear; equidistantly arranged worms are rotatably mounted on the inner wall of the substrate; the outer surface of each worm meshes with the outer surface of a corresponding worm gear; a threaded block is threadedly connected to the outer surface of each adjustment screw; a mounting block is slidably connected to the outer surface of each threaded block; and a die-cutting blade is fixedly connected to the outer surface of each mounting block.
[0006] By adopting the above technical solution, equidistant adjustment grooves are formed on the outer surface of the substrate, and these grooves penetrate the substrate to achieve positioning. Equidistant adjustment screws are arranged on the inner wall of the substrate, configured as rotatable connections to limit the movement of the adjustment screws. The positions of the adjustment screws correspond to the adjustment grooves. A worm gear is installed at the end of each adjustment screw to fix it, allowing the worm gear and adjustment screw to rotate synchronously. The worm is mounted on the inner wall of the substrate, configured as a rotatable connection to limit its movement. The positions of the worm and worm gear correspond, and the worm meshes with the corresponding worm gear, so that when an operator uses a tool to rotate the worm, it can drive... The worm gear rotates, causing the corresponding adjusting screw to rotate. A threaded block is installed on the outer surface of the adjusting screw, and the adjusting screw and the threaded block are connected by a thread. When the adjusting screw rotates, it can drive the threaded block to slide on the inner wall of the adjusting groove. By setting a sliding mounting block on the outer surface of the threaded block, and mounting the die-cutting blade on the surface of the corresponding mounting block, when the adjusting screw moves the threaded block, it can move the mounting block and the die-cutting blade along the direction of the adjusting groove. This allows the operator to adjust the position of the die-cutting blade, thereby changing the size of the processed product and improving the applicability of the device.
[0007] Preferably, the inner wall of each mounting block is threaded with two first bolts, and the outer surface of each first bolt is threaded to the corresponding threaded block.
[0008] By adopting the above technical solution, the first bolt is installed on the inner wall of the corresponding mounting block, and the surface of the first bolt is connected to the corresponding threaded block. The mounting block and the threaded block can be fixed by the first bolt, so that the die-cutting blade can be installed. Conversely, by removing the first bolt, the mounting block and the die-cutting blade can be disassembled to facilitate the replacement of die-cutting blades of different shapes or sizes, thereby further improving the applicability of the device.
[0009] Preferably, each die-cutting blade has a sponge block on both sides.
[0010] By adopting the above technical solution, sponge blocks are placed on both sides of the die-cutting blade. The elasticity of the sponge blocks can absorb part of the impact force, so that the pressure is evenly distributed along the blade edge, avoiding problems such as incomplete die-cutting, burrs, or breakage caused by uneven pressure.
[0011] Preferably, the outer surface of the substrate is provided with equidistant limiting grooves, and the inner wall of each limiting groove is fixedly connected with two limiting strips.
[0012] By adopting the above technical solution, equidistant positioning grooves are opened on the outer surface of the substrate, and the positioning grooves penetrate the substrate to achieve positioning of the positioning grooves. By installing two positioning strips on the inner wall of the positioning grooves, the positioning strips are fixed.
[0013] Preferably, the outer surface of the substrate has mounting holes arranged at equal intervals, and a second bolt is installed on the inner wall of each mounting hole.
[0014] By adopting the above technical solution, the mounting hole is opened on the outer surface of the substrate. The circular shape of the mounting hole enables the positioning of the mounting hole. The second bolt is installed on the inner wall of the corresponding mounting hole to achieve the positioning and installation of the second bolt.
[0015] Preferably, a die-cutting roller is provided below the substrate, and the outer surface of the die-cutting roller is provided with fixing holes arranged at equal intervals.
[0016] By adopting the above technical solution, a die-cutting roller is set below the substrate, and the bottom surface of the substrate is adapted to the outer surface of the die-cutting roller, so that the substrate can be attached to the surface of the die-cutting roller, thereby enabling the substrate to be mounted on the surface of the die-cutting roller. Fixing holes arranged at equal intervals are opened on the outer surface of the die-cutting roller to achieve positioning of the fixing holes.
[0017] Preferably, each of the second bolts is adapted to a corresponding fixing hole.
[0018] By adopting the above technical solution, the second bolt is adapted to the corresponding fixing hole, so that the second bolt can fix the substrate on the surface of the die-cutting roller through the connection with the mounting hole and the fixing hole, thereby realizing the installation of the substrate.
[0019] Preferably, each of the limiting grooves is provided with a third bolt inside, and each of the third bolts is adapted to a corresponding fixing hole.
[0020] By adopting the above technical solution, the third bolt is set inside the limiting groove. The third bolt can be installed by matching the third bolt with the fixing hole. When it is necessary to adjust the position of the substrate on the die-cutting roller surface, the third bolt is connected to the corresponding fixing hole. By matching the third bolt with the limiting groove and the limiting strip, the substrate can slide on the outer circumferential surface of the die-cutting roller. After sliding to the designated position, the third bolt is tightened. Then the second bolt is connected to the mounting hole and the fixing hole, so that the position of the substrate on the die-cutting roller surface is adjustable.
[0021] In summary, this application includes at least one of the following beneficial technical effects: This highly adaptable cardboard pressing fixture, equipped with components such as an adjusting screw, worm gear, worm, and mounting block, allows for easy adjustment of the die-cutting blade's position when the product size needs to be changed. Rotating the corresponding worm gear drives the corresponding worm wheel, which in turn drives the adjusting screw. This causes the adjusting screw to slide the threaded block and mounting block within the adjusting groove, allowing the mounting block and die-cutting blade to move along the groove. This facilitates operator adjustment of the die-cutting blade's position, enabling the device to change the product size and enhancing its applicability. A first bolt, installed between the threaded block and the mounting block, secures the mounting block and die-cutting blade to the surface of the threaded block. Conversely, removing the first bolt allows the mounting block and die-cutting blade to be disassembled and replaced, further improving applicability. A limiting groove, limiting strip, and a third bolt, connected to a fixing hole, allow the substrate to slide on the die-cutting roller surface, facilitating adjustment of the substrate's position on the roller surface.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.
[0025] Example 1: A highly adaptable tooling for pressing cardboard; please refer to [link / reference]. Figure 4 , Figure 5 and Figure 6The system includes a substrate 1. The outer surface of the substrate 1 has equidistantly arranged adjustment grooves 2. These grooves penetrate the substrate 1, allowing for positioning. The inner wall of the substrate 1 is rotatably connected to equidistantly arranged adjustment screws 3. Each adjustment screw 3 has a worm gear 4 fixedly connected to its end. The equidistantly arranged adjustment screws 3 on the inner wall of the substrate 1 are rotatably connected, limiting their position. The positions of the adjustment screws 3 correspond to the adjustment grooves 2. Worm gears 4 are installed at the ends of the adjustment screws 3, fixing them and allowing the worm gears 4 and adjustment screws 3 to rotate synchronously.
[0026] Please see Figure 5 and Figure 6 A series of worm gears 5 are rotatably mounted on the inner wall of the substrate 1, arranged at equal intervals. The outer surface of each worm gear 5 meshes with the outer surface of a corresponding worm wheel 4. A threaded block 6 is threadedly connected to the outer surface of each adjusting screw 3. The worm gears 5 are mounted on the inner wall of the substrate 1 in a rotatable connection to limit their movement. The positions of the worm gears 5 and worm wheels 4 correspond, and when the worm gears 5 mesh with their corresponding worm wheels 4, the operator can rotate the worm gears 4 using a tool, thereby causing the corresponding adjusting screw 3 to rotate. A threaded block 6 is installed on the outer surface of the adjusting screw 3, and the adjusting screw 3 and the threaded block 6 are threadedly connected. When the adjusting screw 3 rotates, it can drive the threaded block 6 to slide on the inner wall of the adjusting groove 2. Each threaded block 6 has a mounting block 7 slidably connected to its outer surface, and each mounting block 7 has a die-cutting blade 9 fixedly connected to its outer surface. By setting the sliding mounting block 7 on the outer surface of the threaded block 6 and mounting the die-cutting blade 9 on the corresponding mounting block 7 surface, when the adjusting screw 3 drives the threaded block 6 to move, it can drive the mounting block 7 and the die-cutting blade 9 to move along the direction of the adjusting groove 2. This makes it easy for the operator to adjust the position of the die-cutting blade 9, so that the device can realize the position adjustment of the die-cutting blade 9, so as to change the size of the processed product and improve the applicability of the device.
[0027] Example 2: A highly adaptable tooling for pressing cardboard; please refer to [link / reference]. Figure 6Each mounting block 7 has two first bolts 8 threadedly connected to its inner wall. The outer surface of each first bolt 8 is threadedly connected to the corresponding threaded block 6. The first bolts 8 are installed on the inner wall of the corresponding mounting block 7, and the surface of the first bolt 8 is connected to the corresponding threaded block 6. The mounting block 7 and the threaded block 6 can be fixed by the first bolts 8, so that the die-cutting blade 9 can be installed. Conversely, by removing the first bolts 8, the mounting block 7 and the die-cutting blade 9 can be disassembled to replace the die-cutting blade 9 with different shapes or sizes, further improving the applicability of the device. Each die-cutting blade 9 has a sponge block 10 on both sides. The sponge block 10 is placed on both sides of the die-cutting blade 9. The elasticity of the sponge block 10 can absorb part of the impact force, so that the pressure is evenly distributed along the blade edge, avoiding problems such as incomplete die-cutting, burrs or breakage caused by uneven pressure.
[0028] Please see Figure 3 , Figure 4 and Figure 5 The outer surface of the substrate 1 is provided with equidistantly arranged limiting grooves 11. Two limiting strips 12 are fixedly connected to the inner wall of each limiting groove 11. The limiting grooves 11 are equidistantly arranged and penetrate the substrate 1 to achieve positioning of the limiting grooves 11. The limiting strips 12 are fixed by installing two limiting strips 12 on the inner wall of the limiting grooves 11. The outer surface of the substrate 1 is provided with equidistantly arranged mounting holes 13. A second bolt 14 is installed on the inner wall of each mounting hole 13. The mounting holes 13 are opened on the outer surface of the substrate 1. The circular shape of the mounting holes 13 achieves positioning of the mounting holes 13. The second bolt 14 is installed on the inner wall of the corresponding mounting hole 13 to achieve positioning and installation of the second bolt 14.
[0029] Please see Figure 1 , Figure 2 and Figure 3 A die-cutting roller 15 is provided below the substrate 1. The outer surface of the die-cutting roller 15 is provided with equally spaced fixing holes 16. The bottom surface of the substrate 1 is adapted to the outer surface of the die-cutting roller 15, so that the substrate 1 can be attached to the surface of the die-cutting roller 15, thereby allowing the substrate 1 to be mounted on the surface of the die-cutting roller 15. The equally spaced fixing holes 16 are provided on the outer surface of the die-cutting roller 15 to achieve positioning of the fixing holes 16. Each second bolt 14 is adapted to the corresponding fixing hole 16. By adapting the second bolt 14 to the corresponding fixing hole 16, the second bolt 14 can fix the substrate 1 to the surface of the die-cutting roller 15 through the connection with the mounting hole 13 and the fixing hole 16, thereby realizing the installation of the substrate 1.
[0030] Please see Figure 4 and Figure 5Each limiting groove 11 is provided with a third bolt 17 inside, and each third bolt 17 is adapted to the corresponding fixing hole 16. The third bolt 17 is placed inside the limiting groove 11. Through the adaptation of the third bolt 17 to the fixing hole 16, the third bolt 17 can be installed. When it is necessary to adjust the position of the substrate 1 on the surface of the die-cutting roller 15, the third bolt 17 is connected to the corresponding fixing hole 16. Through the adaptation of the third bolt 17 to the limiting groove 11 and the limiting strip 12, the substrate 1 can slide on the outer circumferential surface of the die-cutting roller 15. After sliding to the designated position, the third bolt 17 is tightened. Then the second bolt 14 is connected to the mounting hole 13 and the fixing hole 16, so that the position of the substrate 1 on the surface of the die-cutting roller 15 is adjustable.
[0031] The implementation principle of this application embodiment is as follows: First, the mounting block 7 is installed on the surface of the threaded block 6 by the first bolt 8, at which time the die-cutting blade 9 is fixed. Then, the second bolt 14 and the third bolt 17 are connected to the fixing hole 16, so that the substrate 1 and the die-cutting blade 9 are fixed on the surface of the die-cutting roller 15. When it is necessary to change the size of the processed product, the operator rotates the corresponding worm 5 to mesh with the corresponding worm wheel 4, so that the worm wheel 4 can drive the corresponding adjusting screw 3 to rotate. Through the connection between the adjusting screw 3 and the threaded block 6, the mounting block 7 and the die-cutting blade 9 can move along the adjusting groove 2. The direction of movement allows for adjustment of the position of the die-cutting blade 9, facilitating changes in the size of the processed product and improving the applicability of the device. When the die-cutting blade 9 needs to be replaced, the first bolt 8 is removed, allowing the mounting block 7 and the die-cutting blade 9 to be detached, and then the required die-cutting blade 9 can be replaced. When the position of the substrate 1 needs to be adjusted, the corresponding second bolt 14 is removed, and the third bolt 17 is loosened. At this time, the substrate 1 and the die-cutting blade 9 can slide along the direction of the limiting groove 11 on the surface of the die-cutting roller 15, thereby making it easy to adjust the position of the substrate 1 and the die-cutting blade 9 on the surface of the die-cutting roller 15.
