DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0021] Embodiment 1

[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The present invention provides a technical solution: a quick-change device for coiling side guide plates, including a conveying frame 100, a rotating shaft 102 rotatably arranged at the bottom of the conveying frame 100, and a bottom roller 101 sleeved and fixed outside the rotating shaft 102. A strip steel is conveyed above the bottom roller 101, and the strip steel is located between two side guide plate bodies 103. Side guide plate bodies 103 are arranged on both sides of the top of the conveying frame 100. Two disassembly and assembly mechanisms are arranged on the bottom roller 101. The disassembly and assembly mechanism includes a bracket 201 and two moving plates 206. A servo motor 200 is arranged on the bracket 201. By driving the bidirectional lead screw 202 to rotate through the servo motor 200, two clamping plates 207 can be driven to move. The working end of the servo motor 200 is fixedly provided with a bidirectional lead screw 202, and two nut blocks 203 are arranged outside the bidirectional lead screw 202. A clamping plate 207 is arranged on the side of the moving plate 206;

[0023] A connecting frame 210 is fixedly arranged between the nut block 203 and the moving plate 206. A limiting plate 205 is fixedly arranged at the end of the bidirectional lead screw 202. The limiting plate 205 can prevent the nut block 203 outside the bidirectional lead screw 202 from disengaging from the bidirectional lead screw 202 during rotation;

[0024] A bearing 209 is fixedly arranged inside the bracket 201. The bearing 209 can facilitate the rotation of the bidirectional lead screw 202. The working end of the servo motor 200 passes through the inside of the bearing 209. A support plate 208 is fixedly arranged on the side of the bracket 201, and the servo motor 200 is fixed on the support plate 208;

[0025] Two counterbores 214 are formed inside the clamping plate 207, and screws are arranged inside the counterbores 214. After long-term use, when the clamping plate 207 is worn due to long-term contact with the side guide plate body 103, the screws can be unscrewed to remove the clamping plate 207 for replacement, and the working ends of the screws extend into the inside of the moving plate 206.

[0026] Embodiment 2

[0027] Based on Embodiment 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , a limiting member for limiting the nut block 203 is provided on the back surface of the bracket 201. The limiting member includes a limiting rod 211. Two groups of limiting rings 213 are provided on the outside of the limiting rod 211. The limiting rings 213 slide on the limiting rod 211, which can limit the movement of the nut block 203 on the bidirectional lead screw 202. A connecting rod 212 is fixedly provided between the limiting ring 213 and the nut block 203. A fixing plate is fixedly provided between the end of the limiting rod 211 and the bracket 201.

[0028] Through the designed disassembly and assembly mechanism of the present utility model, during use, the rotation of the bidirectional lead screw 202 drives the nut blocks 203 to move towards or away from each other, thereby driving the clamping plates 207 on the moving plate 206 to move to clamp or release the side guide plate main body 103, and then disassembling and assembling the side guide plate main body 103 to achieve quick replacement operation and improve the quick replacement efficiency of the side guide plate main body 103.

[0029] During use, place the side guide plate main body 103 between the two clamping plates 207. Start the servo motor 200. At this time, the working end of the servo motor 200 rotates to drive the bidirectional lead screw 202 to rotate. At this time, the nut blocks 203 located outside the bidirectional lead screw 202 convert the rotary motion into a linear motion. The two nut blocks 203 rotate in the opposite direction, driving the connecting frame 210 to move. The connecting frame 210 drives the moving plate 206 to move, thereby driving the clamping plates 207 to move. Subsequently, the two clamping plates 207 contact and clamp the side guide plate main body 103, and then the side guide plate main body 103 is installed. When replacing the side guide plate main body 103, operate according to the reverse principle above.

[0030] Embodiment 3

[0031] Based on Embodiment 2, please refer to Figure 1 , Figure 2 , Figure 3 , supporting members for supporting the side guide plate main body 103 are provided on both the front and back surfaces of the bracket 201. The supporting members include support plates 300. Support rods 301 are fixedly provided on the side surfaces of the support plates 300. The ends of the support rods 301 can pass through the inside of the sliding grooves in the side guide plate main body 103. Sliding grooves for the ends of the support rods 301 to pass through are formed inside the side guide plate main body 103.

[0032] Through the designed supporting members of the present utility model, the side guide plate main body 103 can be supported when taking and placing the side guide plate main body 103 during the disassembly and assembly process, and it is not necessary to always hold the side guide plate main body 103 during the taking and placing process, which is convenient for operation.

[0033] Place the side guide plate body 103 between two sets of clamping plates 207 and hang the side guide plate body 103 on the ends of two sets of support rods 301. Then, the two sets of clamping plates 207 can clamp and fix the clamping plates 207 located on the support rods 301. When removing the side guide plate body 103, operate according to the reverse principle described above. Finally, the two sets of clamping plates 207 loosen and leave the surface of the side guide plate body 103. Then, move the side guide plate body 103 towards the middle position of the conveying rack 100 and pull it out. There is no need to hold the side guide plate body 103 all the time during the process of taking and placing.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
