Description

Technical Field

[0001] The utility model relates to the field of strip winding, in particular to a disc-type retractable and reeling air top loading device. Background Art

[0002] The unwinding and rewinding mechanism is the unwinding or rewinding part of the coil processing production line. When unwinding, it is mainly used to unwind the rolled raw materials mechanically, and when rewinding, it is mainly used to rewind the raw materials into coils mechanically. Unwinding and rewinding mechanisms are widely used in paper rolls, cloth rolls, plastic rolls and metal coil processing production lines, and are designed in a variety of ways according to actual process requirements. Among them, the disc-type unwinding and rewinding mechanism is the most widely used due to its good structural strength.

[0003] The existing disc-type winding and unwinding mechanism mainly uses a safety chuck structure symmetrically arranged on two discs to clamp the material shaft, so that the material shaft can be driven to rotate to realize the winding or unwinding of the strip, and the material shaft can be switched by driving the disc to rotate. When installing the material shaft, the foot of the safety chuck needs to be fixed, and the material shaft is installed in the card slot of the safety chuck. The card slot of the safety chuck can be manually pushed to open and automatically return to its position when rotating. The tail end of the safety chuck drives the chuck to rotate through the motor transmission, thereby driving the rotation of the material shaft. When the general safety chuck clamps the material shaft, it usually tilts the disc to produce a rotation angle, and there is a certain gap. In the process of winding and unwinding, the occasions with strict requirements on the winding and unwinding accuracy of the roll width often cannot meet the requirements, resulting in uneven winding and unwinding of the roll material. At the same time, when switching material shafts of different length specifications, the operation is also more troublesome, and the material change time is longer, which affects the work efficiency.
