Winding and switching control system for wide lead tape production line

Abstract

The invention discloses a winding and switching control system for a wide lead tape production line. The system is arranged behind a tape feed device and comprises a PLC (programmable logic controller) control system, a cutter and a winding device used for receiving lead tapes conveyed by the tape feed device, the winding device comprises two winding channels, two corresponding winding rollers and two corresponding winding motors, and the control system further comprises a buffer mechanism arranged between the tape feed device and the winding device. The PLC control system judges tension change of the lead tapes by monitoring the state of the buffer mechanism and controls the winding speed of the winding device according to judging results, so that the tape feed device cannot stop conveying the lead tapes due to switching of the winding channels and tap cutting, and the lead tapes cannot be accumulated in front of the cutter. For example, the buffer mechanism is composed of an angle transducer, supporting plates and a cylinder. The tape feed device does not stop conveying the lead tapes, accumulation of the lead tapes in front of the cutter is eliminated, and tape cutting and automatic switching of the channels are achieved, so that production efficiency of the lead tape production line is improved.

Description

technical field [0001] The invention relates to a winding switching control system for a lead strip production line, in particular to a winding switching control system for a wide lead strip production line. Background technique [0002] Existing lead strip production mainly includes processes such as refining lead, casting, strip cutting, rolling, drying, etc., and finally the finished lead strip is rolled to facilitate storage and transportation. In the rewinding process, two rewinding motors respectively drive two rewinding rollers to complete the rewinding of the lead belt, although it is assumed that the control can be switched between the two rewinding rollers to achieve uninterrupted rewinding. However, since the winding device and the tape feeding device are not completely synchronized during the entire winding process, such as when switching the winding rollers, due to the delay caused by the switching, the lead tape output by the tape feeding device is accumulated ...

AI Technical Summary

Problems solved by technology

However, since the winding device and the tape feeding device are not completely synchronized during the entire winding process, such as when switching the winding rollers, due to the delay caused by the switching, the lead tape output by the tape feeding device is accumulated during the switching process. In front of the knife, the purpose of uninterrupted winding has not been achieved; in addition, such a switch will cause irregular deformation of the lead tape roll after the roll change

[0003] The existing technology has improved this. Before the roll is changed, the delivery of the lead belt is stopped first, and the lead belt is not started until the cutter cuts the lead belt and the channel is replaced. However, due to frequent roll changes, the existing technology makes the lead belt production line Frequent stop and start not only greatly reduces the working efficiency of the winding device, but also shortens the service life of each part of the winding device
