Description

Technical Field

[0001] The utility model belongs to the technical field of breathable film processing, in particular to a slitting mechanism for rolling up a breathable film. Background Art

[0002] Breathable membrane is a material used in building waterproofing. It is usually made of polymer materials and has a special microporous structure, which is both waterproof and breathable. During the production and processing of breathable membranes, the breathable membranes need to be rolled up to form cylindrical membrane rolls for easy transportation and use. During the rolling process, the wider breathable membranes need to be cut using a slitting mechanism so that the width of the breathable membranes meets the processing requirements.

[0003] In the Chinese utility model patent with the announcement number CN218138474U, a breathable film collection and slitting machine is provided. By using the mutual cooperation of the moving mechanism, the position of the movable sleeve can be moved, and then the position of the slitting knife can be moved. By using the length scale on the fixed frame, the slitting knife is adjusted to the appropriate position to adjust the slitting width of the breathable film, thereby greatly improving the practicality of the slitting machine when in use. However, in the actual production process, the stationary slitting knife of the slitting machine cannot actively cut the breathable film when cutting. Passive cutting easily causes unevenness at the slitting point of the breathable film, and it does not have the function of compacting and assisting the transmission of breathable films of different models and thicknesses. The breathable film is prone to loosening during the cutting process, which affects the stability of slitting.

[0004] Therefore, it is urgent to improve the existing breathable film collection and slitting machine and provide a breathable film winding and slitting mechanism with compression and auxiliary transmission functions. Utility Model Content
