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

Embodiment Construction
[0030] The present invention is further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0031] like figure 1 As shown, it is a schematic structural diagram of an embodiment of the adjustable biaxial transmission type rewinding and unwinding device of the present invention. The adjustable biaxial transmission type rewinding and unwinding device in this embodiment includes two brackets 1 located at both ends. The two brackets 1 are correspondingly provided with coaxial mounting holes, and the mounting holes are provided with disc-type mounting holes for clearance fit therewith. In the roller frame 2, at least two rewinding and unwinding rollers 3 are arranged between the two disc-type roller frames 2 to cooperate with them in rotation. The number of retracting and unwinding roll...

The invention discloses an adjustable double-shaft transmission type winding and unwinding device. The adjustable double-shaft transmission type winding and unwinding device comprises two supports located at the two ends correspondingly. The two supports are provided coaxial installation holes correspondingly. A disk type roller frame is arranged in each installation hole. Winding and unwinding rollers are arranged between the two disk type roller frames. The supports are each provided with a rotary support unit. Each rotary support unit comprises two baffles, wherein a rotary shaft is arranged between the two baffles. Each rotary shaft is sleeved with a bearing I. The two baffles are each provided with a bearing II. An installation seat is arranged under each of the two supports. At least two sliding rails are arranged on the installation seats. Chutes are arranged at the bottoms of the supports correspondingly. Adjusting bases are arranged on the bottom faces of the installation seats correspondingly. Each adjusting base comprises a bottom plate and an inclined adjusting plate. A matching face between each bottom plate and the corresponding inclined adjusting plate is a bevel arranged obliquely relative to the axes of the winding and unwinding rollers. An adjusting mechanism which is used for driving each bottom plate to move relative to the corresponding inclined adjusting plate is further arranged between the corresponding bottom plate and the corresponding inclined adjusting plate. The adjustable double-shaft transmission type winding and unwinding device further comprises a driving mechanism used for driving the disk 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 transmission type winding and unwinding mechanism capable of adjusting the lateral position and the horizontal position of a winding and unwinding roller. Background technique [0002] The rewinding and unwinding 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 by mechanical means, and when rewinding, it is mainly used to mechanically wind the raw materials into rolls. The rewinding and unwinding mechanism is widely used in the paper roll, cloth roll, plastic roll and metal coil processing production line, and the design is diversified according to the 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 bracke...
