[0035] The following will be described in detail in combination with the accompanying Figure 1 - Figure 6 The present application will be further described in detail.

[0036] This application discloses a winding machine changing device.

[0037] Reference Figure 1 - Figure 3 , Figure 6 A winding machine changing device includes four winding rollers 3 movably arranged inside the winding machine body 1. The four winding rollers 3 are grouped in pairs. One end of one group of winding rollers 3 located at the lower end of the winding machine body 1 is fixedly provided with a set of transmission structures. One winding roller 3 is provided with a set of transmission structures at one end of the motor at the lower end of the winding machine body 1. The two ends of the winding roller 3 are symmetrically provided with quick-release mechanisms 2 with the same structure.

[0038] The quick-release mechanism 2 includes a fixed frame 201 fixed above the main body 1 of the coiling machine, and a movable plate 204 slidably disposed inside the fixed frame 201. The overall shape of the movable plate 204 is as follows: Figure 3 As shown, the shape of the protrusions on both sides of the concave surface of the fixed frame 201 matches the grooves opened on both sides of the movable plate 204, restricting the movable plate 204 to move only longitudinally. The bearing 207 is fixedly installed inside the movable plate 204. The bearing 207 consists of an inner ring, rolling elements, and an outer ring. Multiple limiting blocks 208 are fixedly installed on the inner side of the inner ring of the bearing 207. Fixed shafts 202 are fixedly installed at both ends of the roller 3. Multiple grooves 215 are opened on the outer surface of the fixed shafts 202. The number and shape of the grooves 215 correspond to the limiting blocks 208.

[0039] The cover plate 203 is movably mounted on the upper end of the bearing 207. Rectangular grooves 210 are formed at both ends of the top surface of the cover plate 203. Rotating shafts 212 are fixedly mounted on both sides of the interior of each of the two rectangular grooves 210. Two support rods 209 are respectively sleeved on the outside of the rotating shafts 212 through circular holes 214 formed in their middle, allowing the support rods 209 to rotate flexibly. Torsion springs 211 are respectively sleeved between the two rotating shafts 212 and the support rods 209. The surface of the torsion spring 211 abuts against the interior of the circular hole 214, and the inner surface of the torsion spring 211 abuts against the outer surface of the rotating shaft 212. Next, the two ends of the two torsion springs 211 are fixed to the surface of the rotating shaft 212 and the inner side of the circular hole 214, respectively, so that the support rod 209 can quickly and automatically reset after rotation. The support rod 209 is in the shape of "L". Two irregular grooves 213 are opened on both sides of the upper end of the fixing frame 201. The bottom surface of the irregular grooves 213 has an arc shape. The shape of the irregular grooves 213 perfectly matches the motion trajectory of the lower end of the support rod 209 rotating at 45 degrees with the rotating shaft 212 as the center. When the torsion springs 211 are in the initial state, the lower end of the support rod 209 will be inserted into the irregular grooves 213.

[0040] Reference Figure 4 - Figure 5The upper end of the screw 205 is movably disposed at the top center of the cover plate 203. The upper end of the movable plate 204 is provided with an opening groove 216. The lower end of the screw 205 movably passes through the upper end of the movable plate 204, and the bottom end of the screw 205 is fixed to the inner bottom surface of the opening groove 216. The upper end of the screw 205 is threaded with a nut 206 for adjusting its longitudinal movement. The nut 206 abuts against the surface of the cover plate 203.

[0041] The implementation principle of the winding machine changing device in this application embodiment is as follows: Before use, the required number of quick-release mechanisms 2 are installed on the main body 1 of the winding machine. When the winding roller 3 needs to be placed, two support rods 209 are pushed in opposite directions simultaneously. The support rods 209 are sleeved on the rotating shaft 212 through the circular hole 214 in the middle. The rotating shaft 212 is fixed on the front and rear sides inside the rectangular groove 210, so that the movable plate 204 rotates 45 degrees in opposite directions with the rotating shaft 212 as the center, thereby stretching the torsion spring 211. At this time, the lower end of the support rod 209 inserted into the irregular groove 213 is disengaged from the irregular groove 213, driving the cover plate 203 to disengage from the top of the fixed frame 201. The bottom end of the screw 205 is fixed to the inner bottom surface of the opening groove 216, thereby driving the movable plate 204 and the screw 205 that passes through and is fixed thereto to disengage from the fixed frame 201 as a whole. Since the winding roller 3 is fixedly provided with fixed shafts at both ends, 202. By aligning and inserting the groove 215 on the fixed shaft 202 with the limiting block 208 fixed inside the bearing 207, the fixed shaft 202 can rotate with the roller 3, thereby driving the bearing 207 to rotate inside the movable plate 204. After the two ends of the roller 3 are fixed with the two quick-release mechanisms 2 respectively, the movable plate 204 and the screw 205 are placed back in the fixed frame 201. At this time, the support rod 209 is pushed again so that its lower end is inserted into the irregular groove 213, and then the support rod 209 is released. At this time, the torsion spring 211 rebounds and drives the support rod 209 to reset, thereby locking the cover plate 203 at the upper end of the fixed frame 201, thus realizing the need for quick replacement of the roller 3. When it is necessary to adjust the height of the roller 3, simply twist the nut 206 on the surface of the screw 205 to make the screw 205 drive the movable plate 204 to move up or down, thereby allowing the roller 3 to be adjusted to a suitable position as needed.

[0042] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
