In the production of capacitor films, slitting machines are a common machine. The film splitting machine consists of an unwinding mechanism, a cutting mechanism, a winding mechanism, functional rollers and the like. The working principle is as follows: the metallized film raw material discharged from the unwinding mechanism passes through the flattening roller and the energizing roller and enters the cutting mechanism, and the raw material is respectively wound into film rolls meeting the standard by the winding mechanism after being cut. After the plastic is rolled into a film, the film is required to be cut into a plurality of parts according to the specified size through a cutting mechanism, and then the film is respectively wound.
theoretically, the rollers such as the flattening roller, the tension roller, the energizing roller, the positioning roller, the winding contact roller and the winding roller should be strictly parallel to each other, but in operation, due to the limitation of the installation accuracy of the equipment and the increase of the abrasion amount of the equipment with the lapse of the service time, the rollers are not strictly parallel to each other, and the deviation increases with the lapse of the service time. If the offset is large during production, the film on one side can receive large tension and generate large deformation, the film on the other side is stressed less, and serious problems of uneven cutting, uneven edge and the like can be caused in the cutting process of the cutter, so that the product can be scrapped.
in the prior art, the parallel state between rollers needs to be checked in the overhauling process, so that very long time is often spent, the production efficiency of equipment is delayed, and the quality problem caused by overlarge offset in the production process cannot be avoided due to shutdown overhauling.
