[0028] Embodiment 1
[0029] A detachable printing press die-cutting structure comprises a blade 1, a fixing hoop 2, a fixing block 5 and a limiting groove 6. A connecting plate 7 is provided on the fixing block 5. The blade 1 is connected to the fixing block 5 through the connecting plate 7. The blade 1 is limited to the die-cutting position of the printing press by the fixing block 5 and is distributed in a circular array. The blade 1 is limited to the die-cutting position of the printing press by the fixing block 5 and is distributed in a circular array on the cross bar, so that the force on the blade 1 is more uniform. This design can reduce the wear or damage caused by excessive local force on the blade 1 and extend the service life of the blade 1. The circular array distribution can ensure the accurate positioning of the blade 1 at the die-cutting position. Each blade 1 is precisely mounted on the fixing block 5 and arranged in a circular array as needed, ensuring the accurate position of the blade 1 during the die-cutting process and improving the accuracy of the die-cutting. The blade 1 is limited to the die-cutting position by the fixing block 5 and is distributed in a circular array on the cross bar, making daily maintenance and maintenance easier. Users can easily check and replace a single blade 1, saving maintenance time and cost. Since the blades 1 are evenly distributed on the annular array, the mutual interference and collision between the blades 1 are reduced, the probability of accidents is reduced, and the safety of operation is improved. The fixed hoop 2 is provided with a limiting groove 6, and the limiting groove 6 is evenly distributed on the fixed hoop 2. The uniform distribution of the limiting groove 6 ensures the stable fixation of the blade 1 on the fixed hoop 2. This design can prevent the blade 1 from sliding or deflecting during use, and improves the stability and reliability of the die-cutting structure. The uniform distribution of the limiting groove 6 makes the blade 1 more evenly stressed. In this way, the wear or damage caused by excessive local force on the blade 1 can be reduced, and the service life of the blade 1 can be extended. The uniform distribution of the limiting groove 6 makes daily maintenance and care easier. The user can check the connection status of the blade 1 and the fixed hoop 2 at any time, and adjust or replace it as needed, which makes maintenance more convenient and quick. The blade 1 is limited and installed in the fixed hoop 2 through the fixing block 5. The length of the fixing block 5 is adapted to the length of the fixed hoop 2, and the length of the fixing block 5 is adapted to the length of the fixed hoop 2, ensuring the fit and tightness between them. The fixed block 5 and the fixed hoop 2 with matching lengths can better cooperate with each other, reducing the risk of loosening during use. This can ensure that the die-cutting structure remains stable under high-speed operation or vibration, thereby improving the safety and reliability of the equipment. The fixed hoop 2 is symmetrically distributed on both sides of the blade 1, and the fixed hoop 2 is symmetrically distributed on both sides of the blade 1 to balance the force exerted on the blade 1. This design ensures that the blade 1 is subjected to more uniform force, avoids deflection or deformation caused by uneven force on the blade 1, and improves the stability and efficiency of die-cutting. The fixed hoop 2 is symmetrically distributed on both sides of the blade 1 to enhance the stability of the die-cutting structure. The force exerted on the blade 1 will be evenly transmitted to the fixed hoop 2, thereby reducing the vibration and swing of the structure and improving the accuracy and effect of die-cutting. The fixed hoop 2 is symmetrically distributed on both sides of the blade 1, making operation more convenient.Since the fixing hoop 2 is symmetrically distributed on both sides of the blade 1, the blade 1 is subjected to more balanced force, which reduces the swing and shaking of the blade 1 during use, and improves the stability and reliability of the die-cutting structure. The fixing block 5 and the fixing hoop 2 are connected and fixed through the first fixing hole 3 and the bolt. Through the first fixing hole 3 and the bolt connection, the connection between the fixing block 5 and the fixing hoop 2 is more firm and stable. This connection method ensures the close fit between the fixing block 5 and the fixing hoop 2, reduces the possibility of loosening or shaking, and improves the stability of the entire die-cutting structure. When the fixing block 5 or the fixing hoop 2 needs to be replaced, the user only needs to loosen the bolts to easily complete the disassembly and replacement operations, saving maintenance time and cost. The bolt connection method allows the connection between the fixing block 5 and the fixing hoop 2 to be flexibly adjusted as needed. The user can adjust the tightness of the bolts to achieve fine-tuning of the fixing block 5 on the fixing hoop 2 to adapt to different die-cutting requirements or working scenarios. This design ensures that the die-cutting structure will not fail or be unstable during operation, and improves the safety and reliability of the equipment. The bolt connection method is suitable for the connection between fixing blocks 5 and fixing hoops 2 of different types and specifications, and has strong versatility and adaptability. The fixing hoop 2 is provided with a first fixing hole 3 and a second fixing hole 4, and the first fixing hole 3 and the second fixing hole 4 are staggered. The staggered first and second fixing holes 4 can enhance the connection stability between the fixing hoop 2 and the fixing block 5. Such a design ensures that the fixing hoop 2 is not easily twisted or deformed when the blade 1 is subjected to force, thereby improving the stability of the entire die-cutting structure. The staggered distribution of the first and second fixing holes 4 makes the fixing points on the fixing hoop 2 more evenly distributed around the blade 1. This can effectively reduce the stress concentration between the fixing points and improve the bearing capacity and service life of the blade 1. The staggered distribution of the fixing holes on the fixing hoop 2 increases the contact area of the blade 1 and improves the firmness of the fixation. Even in the case of high-speed operation or large-amplitude vibration, the connection between the fixing hoop 2 and the blade 1 is more reliable and is not easy to loosen or fall off. Since the fixing holes on the fixing hoop 2 are staggered, the user can choose different fixing points to adjust or replace the blade 1 as needed, and maintenance is more convenient and quick. The fixing hoop 2 is fixed to the crossbar at the die-cutting position of the printer through the second fixing hole 4 and the bolt pre-tightening. The bolt pre-tightening fixation makes the connection between the fixing hoop 2 and the crossbar at the die-cutting position of the printer more firm and reliable. Pre-tightening fixation ensures that the connection point fits tightly, reduces the possibility of loosening or shaking, and improves the stability of the die-cutting structure. The fixing hoop 2 is fixed to the crossbar through the second fixing hole 4, and can accurately position the die-cutting structure. Such a design ensures the precise positioning of the blade 1 at the die-cutting position and improves the accuracy and efficiency of die-cutting. The design of bolt pre-tightening fixation allows the connection between the fixing hoop 2 and the crossbar to be flexibly adjusted as needed. The user can adjust the position of the fixing hoop 2 by loosening and tightening the bolts to adapt to different die-cutting requirements or work scenes, and has strong versatility and adaptability.Due to the bolt pre-tightening, the connection between the fixing hoop 2 and the crossbar is more firm and reliable, and is not easy to loosen or fall off. This design ensures that the die-cutting structure can remain stable under high-speed operation or large-amplitude vibration, thereby improving the safety and reliability of the equipment.
[0030] A detachable printing press die-cutting structure based on Example 1 is used:
[0031] When using this solution for die cutting, first, the user needs to prepare the fixing hoop 2, the fixing block 5, the blade 1 and the crossbar of the die cutting position of the printing press. Next, follow the following process:
[0032] Fixing hoop 2 connection: Fix the fixing hoop 2 on the crossbar at the die-cutting position of the printing press by pre-tightening bolts. This step ensures that the basic frame of the die-cutting structure is firmly fixed.
[0033] The fixing block 5 is connected: the fixing block 5 is fixed to the fixing hoop 2 by bolt connection. The length of the fixing block 5 is adapted to the length of the fixing hoop 2, so that the connection between them is more firm and reliable.
[0034] Installation of blade 1: The blade 1 is limited to a crossbar at the die-cutting position of the printing press by a fixing block 5 and distributed in a circular array. The installation position of the blade 1 is determined by the fixing block 5, and the fixing block 5 is fixed to the crossbar by a fixing hoop 2.
[0035] Symmetrical distribution: Ensure that the fixing hoop 2 is symmetrically distributed on both sides of the blade 1. This balances the force on the blade 1 and improves the stability and reliability of the die-cutting structure.
[0036] Limiting groove 6 design: The limiting grooves 6 on the fixing hoop 2 are evenly distributed, which helps to accurately locate the position of the blade 1 on the fixing hoop 2. This step ensures the stable fixation of the blade 1 and improves the accuracy and efficiency of die cutting.
[0037] Bolt connection: Finally, the fixing hoop 2 is connected to the fixing block 5 and the fixing hoop 2 is connected to the crossbar by bolts. This step enhances the firmness and stability of the connection and ensures the safety of the die-cutting structure during use.
[0038] In summary, when the user performs die-cutting operations, he first connects the fixing hoop 2 with the crossbar, then installs the fixing block 5 and the blade 1 on the fixing hoop 2, and finally connects and fixes the components with bolts. Such an operation process is simple and easy, and ensures the stability and reliability of the die-cutting structure, meeting the user's needs for die-cutting operations.
