Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting swing roller technology, and mainly to a stable guiding intermittent die-cutting swing roller structure. Background Technology
[0002] Intermittent operation of die-cutting machines requires frequent acceleration and deceleration, which increases wear on the swing rollers and related components, potentially shortening the equipment's lifespan. It also leads to increased energy consumption, and the intermittent swing rollers require more frequent maintenance and component replacement, increasing maintenance costs.
[0003] During startup and shutdown, the precise control of the oscillating rollers may be affected, which may lead to a decrease in die-cutting accuracy. In high-speed production, intermittent oscillating rollers may have difficulty maintaining stable die-cutting quality, especially when handling thin or fragile materials.
[0004] The oscillating roller of the intermittent die-cutting machine performs high-speed repetitive linear motion. The lower the friction coefficient of the oscillating roller guide mechanism, the better it is for the high-speed response of the oscillating roller. The original solution used HIWIN linear guides, but in the actual test process, the starting friction was large and could not match the system's response speed. Utility Model Content
