[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides two technical solutions: Figures 1-5 The first embodiment of the automatic steel coil docking machine is shown: an automatic steel coil docking machine includes a base 1, two support plates 101 are fixedly connected to the top of the base 1, a cutting mechanism 2 is provided on the support plates 101 for cutting steel coils, a limit mechanism 3 is provided on the base 1, and also includes; The cutting mechanism 2 includes a connecting plate 201 fixedly connected to one side of two support plates 101 that are close to each other. A first hydraulic actuator 202 is fixedly connected to the outer wall of the connecting plate 201. A first hydraulic rod 203 is fixedly connected to the output end of the first hydraulic actuator 202. A first fixing plate 204 is fixedly connected to the side of the first hydraulic rod 203 away from the first hydraulic actuator 202. A cutter 205 is fixedly connected to the outer wall of the first fixing plate 204. A plurality of sliding shafts 206 are slidably connected to the inner wall of the first fixing plate 204. A first spring 207 is fixedly connected to the outer wall of the plurality of sliding shafts 206 respectively. The outer wall of the first spring 207 is fixedly connected to the outer wall of the first fixing plate 204. The sliding shaft 206 is located inside the first spring 207. A pressing plate 208 is fixedly connected to the outer wall of the sliding shaft 206. A fixing component is provided on the support plate 101. A welding component is provided on the fixing component.

[0019] The fixing assembly includes a second hydraulic unit 209 fixedly connected to the outer wall of two support plates 101 respectively, a second hydraulic rod 210 fixedly connected to the output end of the two second hydraulic units 209, and a second fixing plate 211 fixedly connected to the side of the two second hydraulic rods 210 away from the second hydraulic units 209 for fixing the steel strip. The outer wall of the second fixed plate 211 is slidably connected to the inner wall of the support plate 101. Two electric push rods 212 are fixedly connected to the outer wall of the second fixed plate 211 on the left side, and support blocks 213 are fixedly connected to the outer walls of the two electric push rods 212.

[0020] The welding assembly includes a motor 214 fixedly connected to the outer wall of the support block 213. The output shaft of the motor 214 is fixedly connected to a lead screw 215 via a coupling. A movable block 216 is threadedly connected to the outer wall of the lead screw 215. The outer wall of the movable block 216 is slidably connected to the inner wall of the support block 213. The outer wall of the movable block 216 is fixedly connected to a welder 217 for welding steel strips. The outer wall of the support block 213 is fixedly connected to two support shafts 218. The outer walls of the two support shafts 218 are slidably connected to sliding blocks 219. The outer walls of the two sliding blocks 219 are slidably connected to the inner wall of the support plate 101. The support shafts 218 are used to support the support block 213.

[0021] When a steel coil is used up, a new steel coil is stacked on top of the old one, with a certain overlap. Then, the two second hydraulic actuators 209 are activated by the external controller, causing the two second hydraulic rods 210 to move. Simultaneously, the two second fixing plates 211 move, fixing the new and old steel coils together. Then, the first hydraulic actuator 202 is activated by the external controller, causing the first hydraulic rod 203 to move downwards, simultaneously moving the first fixing plate 204. During the downward movement of the first fixing plate 204, the extrusion plate 208 will first contact... When the old and new steel strips are connected, the extrusion plate 208 continues to compress, causing the sliding shaft 206 to slide within the first fixed plate 204. During this sliding process, the first spring 207 is stretched, and the spring 207 itself provides a reaction force, continuously compressing the extrusion plate 208, thus ensuring the extrusion plate 208 continuously fixes the steel coil. After the sliding shaft 206 slides a certain distance within the first fixed plate 204, the cutter 205 contacts the surface of the steel strip, cutting the old and new steel strips. The first hydraulic actuator 202, controlled by an external controller, causes the first fixed plate... 204 rises and returns to its original position. At this point, the worker collects the cut steel strip. Then, the external controller activates two electric push rods 212, which move the support block 213. As the support block 213 moves, the support shaft 218 slides inside the sliding block 219, providing additional support for the support block 213. When the support block 213 moves to the position where the old and new steel strips overlap, the cutter 205 cuts both the old and new steel strips simultaneously, ensuring a proper fit. At this point, the external controller activates the motor 214, which rotates the lead screw 215. When the lead screw 215 rotates, the moving block 216 moves continuously within the support block 213, thereby driving the welder 217 to weld evenly on the new and old steel strips. This mechanism fixes the steel strip through the second fixed plate 211 and the extrusion plate 208 to prevent the steel strip itself from shifting during cutting, which would cause cutting errors. Furthermore, the cutter 205 cuts the new and old steel coils simultaneously, ensuring a perfect overlap at the ends. Then, the motor 214 drives the welder 217 to move and weld the new and old steel coils, thus completing the automatic docking of the new and old steel coils.

[0022] Figure 6The second embodiment is shown. The main difference between this embodiment and the first embodiment of the automatic steel coil docking machine is that the limiting mechanism 3 includes a bidirectional lead screw 301 rotatably connected to the inner wall of the base 1. Two frames 302 are threadedly connected to the outer wall of the bidirectional lead screw 301. The outer walls of the two frames 302 are slidably connected to the inner wall of the base 1. Moving plates 303 are slidably connected to the inner walls of the two frames 302 respectively. A telescopic rod 304 is fixedly connected to the outer wall of the moving plate 303. A limiting plate 305 is fixedly connected to the side of the telescopic rod 304 away from the moving plate 303. The limiting plate 305 is close to the telescopic rod. A second spring 306 is fixedly connected to one side of 304. The end of the second spring 306 away from the limiting plate 305 is fixedly connected to the outer wall of the moving plate 303. The telescopic rod 304 is located inside the second spring 306. Several limiting blocks 307 are fixedly connected to the outer wall of the frame 302 to limit the position of the limiting plate 305. A knob 308 is fixedly connected to the outer wall of the bidirectional lead screw 301. A limiting shaft 309 is inserted into the inner wall of the knob 308. The outer wall of the limiting shaft 309 is inserted into the inner wall of the base 1. The limiting shaft 309 is used to limit the rotation angle of the knob 308.

[0023] When connecting steel coils of different widths, first remove the limiting shaft 309 from the knob 308, then manually turn the knob 308 to rotate the double-acting screw 301. As the double-acting screw 301 rotates, the two frames 302 move closer or further apart to accommodate steel coils of different widths. When accommodating steel coils of different thicknesses, first manually pull the limiting plate 305 away from the frame 302, thus stretching the telescopic rod 304 and the second spring 306. Then, the moving plate 303 can be moved up and down. When it reaches the appropriate position, release the limiting shaft. When plate 305 is in place, the reaction force of the second spring 306 will pull the limiting plate 305, causing the limiting plate 305 to engage with the limiting blocks 307. The spacing between the numerous limiting blocks 307 is preset to accommodate steel coils of different thicknesses. This mechanism can manually adjust the spacing between the two frames 302 to accommodate steel coils of different widths. At the same time, the position of the moving plate 303 within the frame 302 can also be adjusted to accommodate steel coils of different thicknesses. When the steel coil passes through the frame 302, the position of the steel coil conveying can be positioned to prevent positional deviations during conveying and docking.
