Description

Technical Field

[0001] This utility model relates to the field of die-cutting plate technology, specifically a quick-change device for die-cutting plate cutter lines. Background Technology

[0002] Die-cutting plates are essential tools in the printing and packaging industry. They are used to cut and crease materials by installing specific blades. The blades are fixed by embedding them into pre-cut slots at the bottom of the die-cutting plate. Traditionally, the installation and replacement of blades mainly rely on manual methods, such as using a hammer to knock the blade into place or using tools to pry it out of the pre-cut slot. This method has many drawbacks: First, the operation is time-consuming, labor-intensive, and inefficient, especially on production lines that require frequent blade changes, which seriously affects equipment utilization. Second, manual knocking is prone to damage, deformation, or breakage of the pre-cut slot due to uneven force or operational errors, which shortens the service life of the die-cutting plate and blades and increases production costs. Utility Model Content

[0003] The purpose of this invention is to provide a quick-change device for die-cutting plate cutter lines, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-change device for die-cutting plate cutting lines, comprising a support platform, a first bracket and a second bracket vertically fixed to the top of the support platform, cylinders fixed to the inner walls of both the first and second brackets, a pressure plate fixed to the telescopic end of the cylinders, a die-cutting plate installed below the pressure plate, and a clamping device installed between the first and second brackets. The clamping device includes an electric push rod, a second horizontal plate and a guide frame, a first horizontal plate fixed to the telescopic end of the electric push rod, two vertical plates fixed to the top of the first horizontal plate, and lead screws passing through the internal threads of the vertical plates. One end is rotatably connected to a fixed block via a bearing. A second horizontal plate is fixedly connected to the top of the vertical plate. Two guide frames are slidably fitted on the outside of the second horizontal plate. Two limiting grooves are opened on the top of the guide frames. A first stop block and a second stop block are fixedly connected to the top two sides of the guide frames, respectively. A bidirectional screw rod passes through the inside of the first stop block. A first clamping plate and a second clamping plate are threaded on the outside of the bidirectional screw rod. Anti-slip plates are fixedly connected to the inner walls of the first clamping plate and the second clamping plate. Fixed plates are fixedly connected to the inner walls of the first bracket and the second bracket. A pre-cut groove is opened at the bottom of the die-cutting plate. A blade is inserted into the pre-cut groove.

[0005] As a preferred embodiment of this utility model, the fixed end of the electric push rod is fixedly connected to the top center of the support platform, and the fixing block is fixedly connected to the bottom of the guide frame.

[0006] As a preferred technical solution of this utility model, the bottom of both the first clamping plate and the second clamping plate are fixedly connected to a limiting block, and the limiting block is slidably connected inside the limiting groove.

[0007] In a preferred embodiment of this invention, one end of the bidirectional screw is rotatably connected to the second stop block via a bearing, and the bidirectional screw and the first stop block are rotatably connected via a bearing.

[0008] As a preferred embodiment of this utility model, the first horizontal plate and the vertical plate are perpendicular to each other, and the vertical plate and the second horizontal plate are perpendicular to each other.

[0009] As a preferred embodiment of this utility model, both the first clamping plate and the second clamping plate are T-shaped structures, with the first clamping plate located on the outer side of the blade and the second clamping plate located on the inner side of the blade.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The electric push rod raises the entire clamping device, precisely moving the first and second clamping plates to the sides of the blade. A rotating screw fine-tunes the lateral position of the guide frame to ensure accurate clamping plate positioning. Then, rotating the bidirectional screw drives the first and second clamping plates to move relative to each other, using their T-shaped structure and anti-slip plate to stably and securely clamp the blade to both sides. Controlling the retraction of the electric push rod smoothly lowers the clamped blade, safely removing it from the pre-grooved slot. Conversely, extending the electric push rod precisely inserts the blade into the pre-grooved slot for installation. This device achieves mechanized blade assembly and disassembly, replacing the traditional method of manual hammering and prying. It not only saves time and effort, greatly improving replacement efficiency and effectively reducing equipment downtime, but also avoids blade damage, deformation, and pre-grooved slot breakage caused by improper hammering. This significantly extends the service life of the die-cutting plate and blades, reduces production costs, eliminates safety hazards during operation, and ensures smooth production.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1 to 4 This utility model provides a quick-change device for die-cutting plate cutter lines, including a support platform 1. A first bracket 2 and a second bracket 3 are vertically fixed to the top of the support platform 1. Cylinders 4 are fixed to the inner walls of both the first bracket 2 and the second bracket 3. A pressure plate 41 is fixed to the telescopic end of the cylinder 4. A die-cutting plate 5 is installed below the pressure plate 41. A clamping device 6 is installed between the first bracket 2 and the second bracket 3. The clamping device 6 includes an electric push rod 61, a second horizontal plate 62, and a guide frame 63. The first horizontal plate 611 is fixed to the telescopic end of the electric push rod 61. Two vertical plates 612 are fixed to the top of the first horizontal plate 611. A lead screw 613 passes through the internal threads of the vertical plates 612. One end of the lead screw 613 is rotatably connected via a bearing. There is a fixed block 614. The top of the vertical plate 612 is fixedly connected to the second horizontal plate 62. Two guide frames 63 are slidably sleeved on the outside of the second horizontal plate 62. Two limiting grooves 64 are opened on the top of the guide frames 63. The top two sides of the guide frames 63 are respectively fixedly connected to the first stop block 65 and the second stop block 66. The inside of the first stop block 65 is penetrated by a bidirectional screw 651. The outside of the bidirectional screw 651 is threaded with a first clamping plate 67 and a second clamping plate 68. Anti-slip plates 69 are fixedly connected to the inner walls of the first clamping plate 67 and the second clamping plate 68. Fixed plates 7 are fixedly connected to the inner walls of the first bracket 2 and the second bracket 3. The bottom of the die-cutting plate 5 is provided with a pre-cut groove 51. A blade 8 is inserted into the pre-cut groove 51.

[0015] Furthermore, the fixed end of the electric push rod 61 is fixedly connected to the top center of the support platform 1, and the fixing block 614 is fixedly connected to the bottom of the guide frame 63. This structure makes the installation of the electric push rod 61 more stable, which is conducive to improving the overall rigidity and smoothness of the material clamp 6. At the same time, through the fixed connection between the fixing block 614 and the guide frame 63, the precise lateral position adjustment of the lead screw 613 on the guide frame 63 is realized.

[0016] Furthermore, the bottom of the first clamping plate 67 and the second clamping plate 68 are both fixedly connected to limit blocks. The limit blocks are slidably connected inside the limit groove 64. The cooperation between the limit blocks and the limit groove 64 can effectively limit the offset of the first clamping plate 67 and the second clamping plate 68 during the movement, ensuring that they move smoothly along the predetermined trajectory under the drive of the bidirectional screw 651, thereby improving the accuracy and reliability of clamping the blade 8.

[0017] Furthermore, one end of the bidirectional screw 651 is rotatably connected to the second stop 66 via a bearing, and the bidirectional screw 651 and the first stop 65 are rotatably connected via a bearing. This structure makes the rotation of the bidirectional screw 651 smoother, reduces frictional resistance, and makes it easier for the operator to drive the first clamping plate 67 and the second clamping plate 68 to achieve synchronous centering or separation by rotating the bidirectional screw 651, ensuring uniform and stable clamping force.

[0018] Furthermore, the first horizontal plate 611 and the vertical plate 612 are perpendicular to each other, and the vertical plate 612 and the second horizontal plate 62 are perpendicular to each other. This vertical arrangement structure enhances the overall rigidity and stability of the clamp 6, which helps to keep the structure from deforming during lifting and clamping, and ensures that the installation and disassembly of the blade 8 are accurate and reliable.

[0019] Furthermore, both the first clamping plate 67 and the second clamping plate 68 are T-shaped structures. The first clamping plate 67 is located on the outside of the blade 8, and the second clamping plate 68 is located on the inside of the blade 8. The T-shaped structure design increases the contact area between the clamping plate and the blade 8. Together with the anti-slip plate 69, it can effectively prevent the blade 8 from sliding or falling off during the clamping process, ensuring that the clamping is firm and undamaged. At the same time, the arrangement of the inner and outer sides can improve the clamping effect on the blade 8 and prevent the blade 8 from loosening during the assembly and disassembly process.

[0020] Working principle: When using this device, first place the die-cutting plate 5 with the blade 8 to be replaced on the fixed plate 7, start the cylinder 4 to push the pressure plate 41 down to stabilize and fix the die-cutting plate 5, then control the electric push rod 61 to extend, pushing the first horizontal plate 611 and the vertical plate 612 fixed to it to rise, thereby driving the second horizontal plate 62 and the guide frame 63 installed on it to rise as a whole, so that the first clamping plate 67 and the second clamping plate 68 move to both sides of the bottom blade 8 of the die-cutting plate 5. By rotating the screw 613, the fixed block 614 and the guide frame 63 fixed to it can be driven to slide laterally along the second horizontal plate 62, realizing the adjustment of the first clamping plate 67 and the second clamping plate 68. The precise fine-tuning of the lateral position of plate 68 ensures that the distance between the first clamping plate 67 and the blade 8 is equal to the distance between the second clamping plate 68 and the blade 8. Then, the bidirectional screw 651 is rotated to drive the first clamping plate 67 and the second clamping plate 68 to move smoothly towards each other along the limiting groove 64. The T-shaped structure and anti-slip plate 69 are used to firmly clamp both sides of the blade 8. Then, the electric push rod 61 is controlled to retract, thereby driving the clamping device 6 and the blade 8 to move downward, so that the blade 8 can be smoothly and safely removed from the pre-grooved groove 51. When installing a new blade 8, the above operation is repeated. The electric push rod 61 extends to accurately push the blade 8 into the pre-grooved groove 51, completing a fast and reliable installation.

[0021] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
