Description

[0002] In the field of modern fully automatic continuous sheet slitting production lines, in order to meet the needs of the market, the continuous steel plate slitting production line also needs to be transformed into a high-efficiency one. In the original continuous steel plate slitting production line, after the steel plate heads are slit, they will still fit tightly together at the edges of the slits, and the slit steel plate heads need to be introduced into the corresponding coiling machines to be coiled into steel coils. Then, due to structural limitations, there will be a certain distance between the coiling machines and they are not tightly fitted to each other. Then, after the steel plate heads are slit, they cannot be directly sent to the corresponding coiling machines because they are tightly fitted to each other. This requires manual separation of the slit steel plate heads by a certain distance to facilitate their entry into the corresponding coiling machines. Since manual operation is more dangerous and less efficient, it is necessary for technicians in this field to develop a fully automatic steel plate head separation device that can replace manual operation. Therefore, the development of a slitting plate swing arm separation device has become a new industry trend. Utility Model Content
