Description

Technical Field

[0001] The utility model relates to the technical field of rolling mechanisms of strip winding machines, and in particular to a safety rolling mechanism for strip winding machines. Background Art

[0002] Sliver lapping is a preparatory step for combing. A lap lap machine further drafts and combines the drawn slivers into small rolls with straight, horizontally uniform fibers for the comber. After the lap is ejected from the machine, a pneumatic cylinder drives the lap overturning mechanism, which then flips the lap onto a trolley. The lap then returns to its original position.

[0003] In the prior art, the rolling plate and the cylinder connecting rod connector of the strip winding machine are mostly connected in an "O"-shaped closed fixed connection. When the rolling plate encounters other resistance (such as a human body or other objects) during the resetting and downward process, the rolling plate and the cylinder connecting rod cannot be separated, and under the influence of the rolling plate's own weight, it will exert greater pressure on the objects below, which is prone to major personal injury accidents, affecting the production work progress of the factory, and has poor functionality and cannot meet the production use needs.

[0004] Therefore, improvements are made to address the above problems. Utility Model Content
