Disc type winding and unwinding device

Abstract

The invention discloses a disc type winding and unwinding device. The disc 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 in clearance fit with the installation holes are arranged in the installation holes. 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, and bearings II are arranged on the two baffles correspondingly. Installation bases are arranged under the two supports. At least two sliding rails are arranged on each installation base. Sliding grooves 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 which is 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.

Description

technical field [0001] The invention belongs to the technical field of strip winding mechanisms, and in particular relates to a disc-type rewinding and unwinding device. 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 are arranged between the two roller frames, and the two roller frames are respecti...

AI Technical Summary

Problems solved by technology

Although such a rewinding and unwinding mechanism can meet the requirements of use to a certain extent, since the roll frame is directly installed on the support, when the weight of the strip wound on the rewinding and unwinding roller is large, the rotation between the roll frame and the support The fulcrum is subjected to a large force and is easily damaged, resulting in a reduction in the service life and reliability of the rewinding and unwinding mechanism

[0004] In addition, the existing winding and unwinding mechanism is generally fixedly installed on the ground relative to the coil material processing production line. When the winding and unwinding position of the strip is laterally shifted, the winding and unwinding roller of the winding and unwinding mechanism cannot be aligned with the strip. , can’t realize winding and unwinding well

When winding the strip, if the axis of the winding and unwinding roller is not parallel to the surface of the strip, there will be a problem that one end of the strip is tight and the other end is loose during winding, that is, the surface diameter of the coiled strip is different. Equal, 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
