Rewinding shaft tension converting device for cutting and rewinding materials

Abstract

The invention discloses a rewinding shaft tension converting device for cutting and rewinding materials. The rewinding shaft tension converting device comprises a first driving shaft and a second driving shaft. A first toothed belt pulley, a first magnetic powder clutch, a second toothed belt pulley and a second magnetic powder clutch are mounted on a first transmission shaft, and a third toothed belt pulley, a third magnetic powder clutch, a fourth toothed belt pulley and a fourth magnetic powder clutch are mounted on the second driving shaft; a first tension control adjusting power source and a second tension control adjusting power source are connected onto an external power supply circuit, the first magnetic powder clutch and the second magnetic powder clutch are connected with each other in parallel and are connected with the first tension control adjusting power source by a first interlock switch and a first relay, and the third magnetic powder clutch and the fourth magnetic powder clutch are connected with each other in parallel and are connected with the second tension control adjusting power source by a second interlock switch and a second relay. The rewinding shaft tension converting device has the advantages that the rewinding shaft tension converting device is novel and reasonable in design and convenient to popularize and utilize, and can be used and operated conveniently and quickly, tension of a rewinding shaft can be converted by the aid of the rewinding shaft tension converting device, and accordingly the production efficiency and the winding quality of products can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of material slitting machines, in particular to a rewinding shaft tension conversion device for material slitting and rewinding. Background technique [0002] Many packaging materials often go through multiple processes such as slitting, printing (or coating), compounding, and slitting before being used for packaging items, but the cutting methods in each slitting process are different. Common slitting The methods are: (1) trimming, cutting off the process edge material reserved in the previous process, which is mostly used for the processing of materials such as composite films; (2) cutting, cutting the wide coil into multiple rolls of narrow size materials ; (3) Divide the large roll diameter material into several rolls of small roll diameter material, which is equivalent to rewinding and so on. These methods are sometimes used in combination. No matter which process is used, the cut material should meet ...

AI Technical Summary

Problems solved by technology

[0003] In actual production, there are some material processes that require constant adjustment and change of the tension. However, there is no device in the prior art that can realize the tension conversion of the winding shaft on a set of equipment. Usually, only one tension can be used to process the material, which cannot be done quickly. well meet the needs of actual use
