Description

Technical Field

[0001] This utility model relates to the field of protective device technology, and in particular to a protective device for gravure printing rollers. Background Technology

[0002] In the gravure printing industry, the gravure printing roller is a core component that determines the precision and quality of the printed pattern. The fine engraved lines on its surface are easily damaged by collisions and wear, thus requiring specialized protective devices during storage and transportation. However, currently available conventional gravure printing roller protection devices still have significant technical shortcomings in practical applications, failing to meet the dual requirements of efficient roller protection and convenient operation. First, existing protective devices are insufficient in terms of roller fixing and collision protection. Most traditional protective devices use only a simple frame structure and lack shock-absorbing components. During transport, if the roller encounters road bumps or external impacts, it is prone to shaking inside the device, causing it to collide with the frame or rub against the clamping plate, resulting in shaft deformation and surface wear. Second, existing protective devices are cumbersome and inefficient in terms of opening, closing, and portability. Most devices use bolt-fastening structures, requiring the removal of each bolt individually for opening or closing, resulting in numerous steps and a long operation time, thus reducing ease of operation.
