Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting technology, specifically to a structure for adjusting the depth of die-cutting indentation. Background Technology
[0002] Currently, traditional die-cutting refers to a cutting process in the post-processing of printed materials. The die-cutting process can make a die-cutting plate according to a pre-designed pattern for cutting printed materials or other paper products, so that the shape of printed materials is no longer limited to straight edges and right angles. During the die-cutting process, the continuous downward pressure of the die-cutting blade will cause indentations on the cut surface. Over long-term use, the depth of the indentations will affect the quality of the die-cut products. The deeper the indentations, the lower the die-cutting efficiency. In the existing technology, the die-cutting blade does not have an adjustment mechanism, which cannot meet the needs of production and processing. In order to solve the above problems, we propose a die-cutting indentation depth adjustment structure. Utility Model Content
[0003] In view of the problems existing in the above-mentioned die-cutting and creasing depth adjustment structure, this utility model is proposed.
[0004] Therefore, the purpose of this utility model is to provide a die-cutting and creasing depth adjustment structure. By setting the die-cutting blade on the adjustment mechanism, when the die-cutting blade makes a creasing on the die-cutting plane, the die-cutting depth of the die-cutting blade can be changed according to the depth of the creasing, thereby adapting to the spacing error caused by the creasing and improving the quality of the product in the die-cutting process, thus solving the problem of die-cutting and creasing depth adjustment structure.
[0005] To achieve the above objectives, this utility model provides the following technical solution: The die-cutting and creasing depth adjustment structure includes a pressure plate. A rotating hole is formed in the middle of the top of the pressure plate, and a bearing and a lead screw are built into the rotating hole. A concave block is fixedly connected to the top of the lead screw. An adjustment groove is formed at the bottom of the pressure plate, and an adjustment plate is adapted to be placed inside the adjustment groove. A threaded groove is formed in the middle of the top of the adjustment plate. Screw holes are formed at the four corners of the bottom of the adjustment plate. A blade plate is provided at the bottom of the adjustment plate. A die-cutting blade is fixedly installed at the bottom of the blade plate, and bolt holes are formed at the four corners of the bottom of the blade plate.
[0006] Preferably, sliders are fixed on both sides of the adjustment plate, and rod holes are opened in the sliders. Block grooves are opened on both sides of the adjustment plate, and the sliders are built into the inside of the block grooves.
[0007] Preferably, a sliding rod is fixed to the inner wall of the block groove. The sliding rod is adapted to the size of the rod hole, and the end of the sliding rod is inserted into the inside of the rod hole. The sliding rod and the rod hole constitute a sliding mechanism.
[0008] Preferably, the outer ring wall of the bearing is fixedly connected to the inner wall of the rotating hole, and the rotating wall of the bearing is fixedly connected to the outer wall of the concave hole block.
[0009] Preferably, the lead screw and the threaded groove are on the same axis, the thread size of the lead screw and the threaded groove are matched, and they form a rotating mechanism.
[0010] Preferably, a bolt is inserted into the bolt hole, and the end of the bolt is mated to the inside of the bolt hole, forming a rotating mechanism.
[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention uses a die-cutting blade mounted on an adjustment mechanism. When the die-cutting blade creates indentations on the die-cutting plane, the die-cutting depth of the blade can be adjusted according to the depth of the indentations, thereby adapting to the spacing errors caused by the indentations and improving the quality of the product during the die-cutting process.
[0012] This invention uses an adjusting plate that slides and connects with a sliding rod in a block groove via a slider. When the spacing of the adjusting plate is adjusted, it will stabilize the adjustment of the adjusting plate and ensure the stability when adjusting the spacing of the die-cutting blades.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0017] This utility model discloses a die-cutting and indentation depth adjustment structure.
[0018] This utility model provides, for example Figure 1-3 The die-cutting and creasing depth adjustment structure shown includes a pressure plate 1. A rotating hole 2 is provided in the middle of the top of the pressure plate 1, and a bearing 3 and a lead screw 5 are built into the rotating hole 2. A concave block 4 is fixedly connected to the top of the lead screw 5. An adjustment groove 15 is provided at the bottom of the pressure plate 1, and an adjustment plate 6 is adapted to be placed inside the adjustment groove 15. A threaded groove 9 is provided in the middle of the top of the adjustment plate 6. Screw holes 14 are provided at the four corners of the bottom of the adjustment plate 6, and a blade plate 10 is provided at the bottom of the adjustment plate 6. A die-cutting blade 12 is fixedly installed at the bottom of the blade plate 10, and bolt holes 11 are provided at the four corners of the bottom of the blade plate 10. The die-cutting blade 12 is set on the adjustment mechanism. When the die-cutting blade 12 makes a creasing on the die-cutting plane, the die-cutting depth of the die-cutting blade 12 can be changed according to the depth of the creasing, so as to adapt to the spacing error caused by the creasing and thus improve the quality of the product die-cutting process.
[0019] To ensure stability during adjustment of the regulating plate: For example Figure 1 and Figure 2 As shown, sliders 7 are fixed on both sides of the adjusting plate 6, and rod holes 8 are opened in the sliders 7. Block grooves 16 are opened on both sides of the adjusting plate 6, and the sliders 7 are built into the block grooves 16. A sliding rod 17 is fixed on the inner wall of the block groove 16. The sliding rod 17 is adapted to the size of the rod hole 8. The end of the sliding rod 17 is inserted into the inside of the rod hole 8, and the sliding rod 17 and the rod hole 8 form a sliding mechanism. The adapted connection between the sliders 7 and the sliding rod 17 will stabilize the adjustment of the adjusting plate 6 and ensure the stability when adjusting the spacing of the die-cutting blades 12.
[0020] To ensure the rotational limiting and fixing effect on the lead screw: For example Figure 1 and Figure 2 As shown, the outer ring wall of the bearing 3 is fixedly connected to the inner wall of the rotating hole 2, and the rotating wall of the bearing 3 is fixedly connected to the outer wall of the concave hole block 4. When the lead screw 5 rotates, it will be limited by the bearing 3 to ensure that the position of the lead screw 5 remains unchanged when it rotates.
[0021] To drive the adjustment plate for spacing adjustment: For example Figure 2 As shown, the lead screw 5 and the threaded groove 9 are on the same axis. The thread size of the lead screw 5 and the threaded groove 9 are matched and form a rotating mechanism. When the lead screw 5 rotates, the end of the lead screw 5 will rotate inside the threaded groove 9, thereby driving the adjusting plate 6 to rise and fall, thereby changing the spacing during die cutting.
[0022] For the installation and removal of the die-cutting blade: such as Figure 2As shown, a bolt 13 is inserted into the bolt hole 11, and the end of the bolt 13 is connected to the inside of the screw hole 14, forming a rotating mechanism. The die-cutting blade 12 is installed by rotating the bolt 13. The bolt 13 is rotated and connected to the screw hole 14, which completes the installation and disassembly of the die-cutting blade 12.
[0023] During operation and installation, the required die-cutting blade 12 is connected to the bottom end of the adjusting plate 6 via the blade plate 10. The bolt 13 is inserted into the bolt hole 11, and the end of the bolt 13 is rotated and connected to the screw hole 14, thus achieving a quick and limited installation effect for the blade plate 10. During the die-cutting process, the pressure plate 1 can be installed in the hydraulic mechanism of the equipment. The pressure plate 1 will drive the die-cutting blade 12 to cut the product. During the long-term cutting process, indentations will be generated on the cutting surface. At this time, the screw 5 can be driven to rotate by rotating the concave block 4. The concave block 4 will rotate within the rotating wall of the bearing 3, limiting the rotation position of the screw 5. When the screw 5 rotates, the end of the screw 5 rotates within the threaded groove 9, thereby driving the adjusting plate 6 to rise and fall within the adjusting groove 15 to adjust the spacing. During the rising and falling of the adjusting plate 6, the slider 7 will rise and fall within the outer wall of the sliding rod 17 inside the block groove 16 to ensure the stability of the adjustment. Ultimately, the pressing depth of the die-cutting blade 12 is changed to ensure the quality during die-cutting. The design is simple and practical.
[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
