DETAILED DESCRIPTION

[0015] The specific implementation scheme of the utility model is described in detail below in conjunction with the accompanying drawings.

[0016] like Figure 1~Figure 2The adjustable strip steel winding and unwinding device shown in the figure comprises a horizontal rotating shaft 4, the two ends of which are rotatably arranged on the brackets 2 on both sides, the bottoms of the brackets 2 on both sides are fixed on the base 1, a rotating motor 5 is fixed on the bracket 2 on one side, the rotating motor 5 is connected to the rotating shaft 4 by transmission, a rotating disc 3 is fixedly sleeved on the rotating shaft 4, and a plurality of guide sleeves 8 that can rotate around their own axial direction are evenly distributed on the circumference of the two end surfaces near the rotating disc 3 along the radial outward circumference, and the guide sleeves 8 are rotatably sleeved on the guide rod 7. A disc-shaped cavity for winding the strip steel is formed between the outer circumferential surface of the rotating disc 3 and the guide sleeves 8 on both sides, the strip steel is wound on the outer circumferential surface of the rotating disc 3, and the two sides of the strip steel are limited by the guide sleeves 8. In the process of the rotating motor 5 driving the rotating shaft 4 to rotate, the strip steel is driven to be wound or unwound on the rotating disc 3, and the side of the strip steel contacts the guide sleeve 8 during the rotation process, and the guide sleeve 8 rotates around the axial direction to reduce the friction of winding or unwinding the strip steel.

[0017] Specifically, the two ends of any guide rod 7 extend out from the two ends of the guide sleeve 8, and the two ends of the guide rod 7 are fixed on the rotating frame 12 through the fixing plate 13. An adjusting screw 6 is horizontally arranged vertically passing through the middle parts of the two opposite guide sleeves 8. The two ends of the adjusting screw 6 are respectively fixed on the rotating frames 12 on both sides, wherein the rotating frame 12 on one side is fixedly sleeved on the rotating shaft 4, and a nut 10 is threadedly sleeved on the outer end of the pitch-adjusting screw 6 on the rotating frame 12 on the other side. The nut 10 is rotatably arranged on the fixing seat 9, and the fixing seat 9 is arranged on the rotating frame 12 on the same side. A pitch-adjusting motor 11 is also arranged on the fixing seat 9, and the pitch-adjusting motor 11 is transmission-connected with the nut 10. The adjusting motor 11 drives the nut 10 to move horizontally on the pitch-adjusting screw 6, drives the fixing plate 13 on the adjacent side to move horizontally, and the guide sleeve 8 on the adjacent side moves in the direction close to or away from the guide sleeve 8 on the other side, so that the distance between the two sets of parallel guide sleeves 8 on the outer sides of the circumference of the two end surfaces of the turntable 3 changes.

[0018] A sprocket is provided on one end of the nut 10, and the nut 10 is connected to the pitch-adjusting motor 11 through the sprocket. The pitch-adjusting motor 11 drives the nut 10 to rotate through a chain, and the nut 10 moves horizontally on the pitch-adjusting screw 6, and the fixing seat 9 connected to the nut 10 moves synchronously, the fixing plate 13 connected to the fixing seat 9 moves synchronously, and the guide rod 7 and the guide sleeve 8 connected to the same side of the fixing plate 13 move synchronously.

[0019] In addition, the reeling and unreeling devices are provided in two adjacent groups, which are symmetrically arranged on the base 1. The floor space is small.

[0020] Furthermore, the pitch-adjusting screws 6 corresponding to the two symmetrical winding devices are arranged to be connected to each other. The nuts 10 on the winding devices on both sides move on the pitch-adjusting screws 6 respectively, and can adjust the strips of different widths on both sides respectively. When the rotating motor 5 on one side drives the turntable 3 on the same side to rotate, because the same pitch-adjusting screw 6 is applied on both sides, the winding devices on both sides can be driven to rotate at the same time.

[0021] In addition, a rotating sleeve 14 is sleeved on the pitch-adjusting screw rod 6 at the position facing the rotating disk 3. When in contact with the strip steel, the friction force on the winding or unwinding of the strip steel is reduced.

[0022] The working process of the utility model is as follows:

[0023] As shown in Figure 1-2, first, the nut 10 is driven to rotate by the spacing motor 11, and the spacing between the guide sleeves 8 on both sides of the turntable 3 is adjusted according to the width of the strip. Then, one end of the strip is extended from the outer circumference surface close to the turntable 3 and wound on the outer circumference surface of the turntable 3. The rotating motor 5 drives the rotating shaft 4 to rotate, so that the strip is wound on the turntable 3. Finally, after the strip is stored, the rotating motor 5 drives the rotating shaft 4 to rotate in the opposite direction to unwind the strip.

[0024] The above embodiments are only illustrative of the principles and effects of the invention of the utility model, as well as some embodiments of its application, and are not intended to limit the invention of the utility model. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
