[0002] A sheet metal slitting machine is a specialized piece of equipment used for processing metal sheets. It is primarily used to continuously cut wide metal sheets (such as steel coils, aluminum coils, and copper coils) longitudinally into multiple narrow strips. Its core function is to efficiently and precisely slit metal sheets, and it is widely used in steel processing, automobile manufacturing, home appliance production, and the construction industry. Slitting mechanisms are usually installed in the center. When slitting coils, the coil on the unwinding roller needs to be centered to ensure that the coil is accurately positioned when it enters the slitting mechanism, which facilitates the slitting process. Some existing coil slitting devices usually use manual adjustment of the coil to center it, which is time-consuming and labor-intensive, thus reducing processing efficiency. Utility Model Content

[0010] 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.

[0011] Example: Figure 1-4 As shown, this utility model provides an automatic centering device for slitting coils, including an unwinding device 1 and an adjusting assembly 3. The adjusting assembly 3 is installed on the unwinding device 1. The unwinding device 1 includes a fixed frame 101, an unwinding roller 102 slidably inserted in the fixed frame 101, and a support block 103 slidably installed in the fixed frame 101. An arc-shaped groove is formed at the bottom end of the support block 103, and multiple balls 1031 arranged in an array are rolled on the arc-shaped groove. The adjusting assembly 3 includes two symmetrically distributed first limiting plates 302, which are slidably installed in the arc-shaped groove of the support block 103. A bidirectional lead screw 301 is rotatably mounted inside the bracket 101, and the bidirectional lead screw 301 is threaded into the bottom ends of the two first limiting plates 302. A second motor 303 is fixedly mounted on one end of the support block 103, and the output end of the second motor 303 is fixedly connected to one end of the bidirectional lead screw 301. A guide roller assembly 104 is rotatably mounted on one side of the fixing frame 101. The guide roller assembly 104 includes two guide rollers arranged in parallel. Two symmetrically distributed second limiting plates 305 are sleeved through the guide roller assembly 104. A connecting plate 304 is fixedly mounted on the bottom end of each of the two second limiting plates 305, and the first limiting plates 302 are... The top side is slidably mounted on the corresponding connecting plate 304. The coil slitting device mainly includes an unwinding mechanism, a guiding mechanism, a tensioning mechanism, a slitting mechanism, and a winding mechanism. The basic workflow is as follows: the coil to be slitting is mounted on the winding mechanism through the feeding device, the coil is unwound and fed into the production line, the guiding mechanism ensures the accurate position of the coil when it enters the slitting mechanism, the tensioning mechanism maintains the stable tension of the coil during the shearing process, the coil is cut into multiple narrow strips longitudinally by the high-speed rotating disc shears in the slitting mechanism, the cut narrow strips are separated by guide rollers and wound up separately by the winding mechanism. This device forms independent small rolls. It incorporates the unwinding mechanism and centering adjustment device within an existing slitting device for rolled plates. First, the rolled plate to be slitting is placed into the arc-shaped groove of the support block 103 via a transport device. Then, the support block 103 lifts the rolled plate within the fixed frame 101 to a suitable height. Next, the unwinding roller 102 is inserted through and into the inner hole of the rolled plate, with one end of the unwinding roller 102 inserted into a pre-drilled hole on one side of the fixed frame 101. Then, the support block 103 descends a certain distance, bringing the inner wall of the rolled plate into contact with the outer ring of the unwinding roller 102, while ensuring that the support block 103 does not disengage from the rolled plate (e.g., ...). Figure 4As shown in the diagram, during subsequent slitting, as the diameter of the coil decreases, the first hydraulic mechanism 106 drives the support block 103 to rise accordingly, ensuring that the support block 103 always supports the coil. Simultaneously, the support block 103 raises and lowers, causing the first limiting plate 302 to slide and rise on the connecting plate 304. Depending on the width of the coil, the second motor 303 drives the bidirectional lead screw 301 to rotate. The bidirectional lead screw 301 then drives the two first limiting plates 302 to move towards each other. 2. The coil is moved within the arc-shaped groove of the support block 103 for centering adjustment. The ball bearings 1031 within the arc-shaped groove facilitate the movement of the coil within the groove. Simultaneously, the first limiting plate 302 drives two second limiting plates 305 to move synchronously towards each other on the guide roller group 104 via the connecting plate 304. The coil passes between the two guide rollers during transport. The guide roller group 104 can limit and guide the coil during transport. The second limiting plates 305 ensure that the coil remains centered during transport.

[0012] A first hydraulic mechanism 106 is fixedly installed at the bottom of the fixed frame 101, and the output end of the first hydraulic mechanism 106 is fixedly connected to the bottom end of the support block 103. The first hydraulic mechanism 106 drives the support block 103 to slide and rise within the fixed frame 101.

[0013] A mounting frame is slidably installed inside the fixed frame 101. A limiting roller 105 is rotatably installed inside the mounting frame. A second hydraulic mechanism 107 is fixedly installed at the top inside the fixed frame 101, and the output end of the second hydraulic mechanism 107 is fixedly connected to the top of the mounting frame. The second hydraulic mechanism 107 can drive the limiting roller 105 to slide and rise within the fixed frame 101. The limiting roller 105 can limit the winding plate to prevent the winding plate from unwinding.

[0014] A pushing assembly 2 is installed on the fixed frame 101. The pushing assembly 2 includes a slide groove 201, which is fixedly installed on one side of the bottom end of the fixed frame 101. A sliding plate 202 is slidably installed in the slide groove 201, and an unwinding roller 102 is rotatably installed on the top end of the sliding plate 202. A threaded rod 204 is rotatably installed in the slide groove 201, and the threaded rod 204 is threadedly inserted into the bottom end of the sliding plate 202. A first motor 203 is fixedly installed at one end of the slide groove 201, and the output end of the first motor 203 is fixedly connected to one end of the threaded rod 204. The first motor 203 can drive the threaded rod 204 to rotate, and the threaded rod 204 drives the sliding plate 202 to slide along the slide groove 201. The sliding plate 202 drives the unwinding roller 102 to slide in and out of the fixed frame 101.

[0015] Working Principle: In use, the coil to be longitudinally sheared is first placed into the arc-shaped groove of the support block 103 by a conveying device. Then, the first hydraulic mechanism 106 drives the support block 103 and the coil to rise to a suitable height within the fixed frame 101. Next, the first motor 203 drives the threaded rod 204 to rotate, which in turn drives the sliding plate 202 to slide along the slide groove 201. The sliding plate 202 drives the unwinding roller 102 to penetrate into the inner hole of the coil, with one end of the unwinding roller 102 inserted into a pre-drilled hole on one side of the fixed frame 101. Then, the support block 103 is lowered a certain distance so that the inner wall of the coil contacts the outer ring of the unwinding roller 102, and the support block 103 does not disengage from the coil (e.g., Figure 4 (as shown) Then, according to the different widths of the coils, the second motor 303 drives the bidirectional lead screw 301 to rotate. The bidirectional lead screw 301 drives the two first limiting plates 302 to move towards each other. The first limiting plates 302 drive the coil to move in the arc groove of the support block 103 for centering adjustment. The ball bearings 1031 in the arc groove facilitate the movement of the coil in the arc groove. At the same time, the first limiting plates 302 drive the two second limiting plates 305 to move synchronously towards each other on the guide roller group 104 through the connecting plate 304. The coil passes between the two guide rollers in the subsequent conveying. The guide roller group 104 can limit and guide the coil in the conveying process. The second limiting plates 305 can keep the coil centered during the conveying process. Finally, the second hydraulic mechanism 107 drives the limiting roller 105 to slide down within the fixed frame 101, so that the outer ring of the limiting roller 105 contacts the outer ring of the coil but does not press it tightly. The limiting roller 105 can limit the coil to prevent it from unwinding during unwinding.
