Description

Technical Field

[0001] The utility model relates to the technical field of winding and unwinding devices, in particular to a winding and unwinding double 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. The unwinding and rewinding mechanism is widely used in paper rolls, cloth rolls, plastic rolls and metal coil processing production lines, and the design is diversified according to the actual process requirements.

[0003] The traditional unwinding and rewinding includes a symmetrically arranged frame and a swivel arm mounted on the frame. Safety chucks are installed at both ends of the swivel arm. The core shaft of the material roll is clamped by the safety chucks, so that the core shaft is driven to rotate under the action of an external drive, thereby realizing the unwinding and rewinding function. With the popularization of automated production, in order to improve production efficiency, more and more unwinding and rewinding devices using safety chuck structures are replaced by air-top unwinding and rewinding devices. The installation and positioning of the material roll is achieved on one side by the cylinder cone top and on the other side by the manual cone top or the cylinder cone top. Among them, the cylinder cone top has higher requirements for the swivel arm, resulting in a more complex structure of the swivel arm. Therefore, when both ends rely on the air-top cone top, the swivel arm structure is complex, the positioning and adjustment accuracy of the material roll is difficult to control, and there is no simple and convenient single-sided manual cone top adjustment. Therefore, the mainstream air-top unwinding and rewinding device uses a pneumatic cone top group at one end and a manual cone top group at the other end. When unloading materials, the air-top rewinding and unwinding device of this structure needs to manually adjust the manual cone-top group or translate the material toward the cylinder cone-top group, which is troublesome to operate and not conducive to fully automatic production layout.
