Adjustable winding and unwinding device

Abstract

The invention discloses an adjustable winding and unwinding device. The adjustable winding and unwinding device comprises supports located at the two ends. Roller frames are arranged between the two supports. At least two winding and unwinding rollers are arranged between the two roller frames, and the roller frames are rotatably installed on the corresponding supports in a matched mode. Installation bases are arranged under the two supports. At least two sliding rails which are both parallel to the winding and unwinding rollers are arranged on each installation base. Sliding grooves which are matched with the sliding rails are formed in the bottoms of the supports. Adjustment bases are arranged on the bottom surfaces of the installation bases. Each adjustment base comprises a base plate and an oblique adjustment plate fixedly installed on the bottom surface of the corresponding installation base. The matched surfaces between the base plates and the oblique adjustment plates are oblique surfaces which are arranged obliquely relative to the axes of the winding and unwinding rollers. Driving mechanisms used for driving the base plates to move relative to the oblique adjustment plates are further arranged between the base plates and the oblique adjustment plates. By the adoption of the adjustable winding and unwinding device, adjustment of the transverse positions and the horizontal inclination angles of the winding and unwinding rollers can be achieved, and thus winding and unwinding can be better achieved.

Description

technical field [0001] The invention belongs to the technical field of strip winding mechanisms, and in particular relates to a winding and unwinding device which can conveniently adjust the lateral position and inclination angle of a winding and unwinding roller. Background technique [0002] The winding and unwinding mechanism is the unwinding or rewinding part of the coil material processing production line. It is mainly used to mechanically unwind the coiled raw materials during unwinding, and is mainly used to mechanically wind the raw materials into coils during winding. The winding and unwinding mechanism is widely used in paper rolls, cloth rolls, plastic rolls and metal coil processing production lines, and the design is diversified according to actual process requirements. [0003] The existing rewinding and unwinding mechanism generally includes brackets located at both ends, a roller frame is arranged between the two brackets, and at least two rewinding and unwin...

AI Technical Summary

Problems solved by technology

The existing rewinding and unwinding mechanism is generally fixedly installed on the ground relative to the coil material processing production line. When the rewinding and unwinding position of the strip is laterally shifted, the rewinding and unwinding roller of the rewinding and unwinding mechanism cannot be aligned with the strip, and cannot Good realization of rewinding and unwinding

In addition, when winding the strip, if the axis of the winding and unwinding roller is not parallel to the surface of the strip, it will cause the problem that one end of the strip is tight and the other end is loose when winding, that is, the surface of the wound strip The diameters are not equal, and the end with a larger diameter will have a pulling force on the strip, which is not conducive to the coiling operation of the strip, and the strip obtained by coiling may also collapse due to insufficient coiling
