Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, specifically a durable die-cutting roller changing blade mechanism. Background Technology

[0002] Die-cutting machines are commonly used equipment in the printing process. Their main function is to cut various patterns on the stamp by rotating the die-cutting roller. Different patterns correspond to different die-cutting rollers. Therefore, during operation, it is often necessary to change the die-cutting roller blades through the die-cutting roller blade changing mechanism.

[0003] Chinese patent document CN222450671 U discloses a die-cutting roller blade changing mechanism, comprising: a die-cutting machine body, a support plate, and a blade roller. The support plates are fixedly installed on both sides of the die-cutting machine body, and the blade roller is disposed between the two support plates. The left side of the support plate is provided with an anti-warping pressure plate, an arc-shaped baffle, and a vibration rod, and the right side of the support plate is provided with a blade storage device. The beneficial effect is that the storage box can store enough blades and automatically replace them during use, saving the time of manual blade handling and also saving manpower.

[0004] However, in the above solution, when the die-cutting roller changing mechanism on the die-cutting machine needs to remove the die-cutting skin during operation, the motor drives the roller to rotate, which in turn drives the die-cutting skin to rotate. The electric push rod drives the roller and the die-cutting skin to rise slowly. The die-cutting skin will first contact the wedge on the vibrating rod of the die-cutting machine. When the pressure between the wedge and the die-cutting skin is large enough, the wedge will insert into the gap at the head of the die-cutting skin and then remove the die-cutting skin. During long-term use, the wedges that are equidistantly set on the vibrating rod will wear to varying degrees and need to be replaced in time. The operation requires disassembling the entire vibrating rod for replacement, which is cumbersome and inconvenient and requires further improvement and optimization. Utility Model Content
