Double-shaft transmission type winding and unwinding device capable of adjusting horizontal positions of winding and unwinding rollers

Abstract

The invention provides a double-shaft transmission type winding and unwinding device capable of adjusting the horizontal positions of winding and unwinding rollers. The double-shaft transmission type winding and unwinding device comprises two supports which are located at the two ends. Coaxial installation holes are correspondingly formed in the two supports. Disc type roller frames which are clearance fit with the installation holes are arranged in the installation holes. The winding and unwinding rollers are arranged between the two disc type roller frames. Rotary supporting units are arranged on the supports. Each rotary supporting unit comprises two baffles, wherein a rotary shaft is arranged between the two baffles, the rotary shaft is sleeved with a bearing I matched with the peripheral wall of the corresponding disc type roller frame, and bearings II which are matched with the two side walls of the corresponding disc type roller frame are arranged on the two baffles correspondingly. Installation bases are arranged under the two 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. 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. The double-shaft transmission type winding and unwinding device further comprises driving mechanisms used for driving the disc type roller frames and the two winding and unwinding rollers to rotate.

Description

technical field [0001] The invention belongs to the technical field of strip winding mechanisms, and in particular relates to a double-shaft driven winding and unwinding mechanism with adjustable horizontal positions of winding and unwinding rollers. 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 unwinding rollers a...

AI Technical Summary

Problems solved by technology

The drive motor Ⅱ rotates with the roller frame, so it is difficult to arrange the power cord, and during the process of the drive motor Ⅱ rotating with the roller frame, other structures cannot interfere with the drive motor Ⅱ, which takes up a lot of space. When the layout space is limited, it cannot meet the requirements. Requirements
