[0002] Traditional coil centering methods for uncoilers often use mechanical or hydraulic centering devices. These devices achieve centering by adjusting baffles or clamps on both sides of the coil. However, their centering performance is often affected by factors such as operator skill, equipment wear, and coil shape, making high-precision centering difficult to achieve. Utility Model Content

[0003] The purpose of the utility model is to provide a centering device for coiling steel coils on a cold rolling uncoiler, which uses a laser irradiation light source receiving device to adjust the centering of the steel ring. It can not only quickly and accurately center the steel ring, but also stably prevent it from tipping over and falling during coiling, thereby reducing unnecessary losses.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The height of the laser can be adjusted according to the height of the steel coil, and it should be at the same horizontal level as the light source receiving device and at the same height as the axis of the transport trolley; it is convenient for centering adjustment. When the laser projected laser can illuminate the light source receiving device without being blocked by the steel coil, it means that the steel coil is in the center, and the transport trolley body can directly deliver the coil to the reel along the track slide.

When the hydraulic system of the transport trolley is raised to its highest position, alignment is faster. The anti-skid bar on the body of the transport trolley can better prevent the steel ring from slipping during transportation. A marking ruler is installed on the body of the transport trolley. When the steel ring is fixed by the anti-skid bar, the position of the mark on the outer side of the steel ring and the marking ruler can be used to visually observe whether the steel ring meets the specified size and better connect it to the reel. The height of the laser and light source receiving device can be adjusted according to actual working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a centering device for coiling a steel coil of a cold rolling uncoiler, comprising a base 1, a hoisting device 2 for hoisting a steel ring is installed on the base 1, the hoisting device 2 comprises a hoisting bracket 21, a steel cable 23 is provided on the hoisting bracket 21, a steel ring clamp 22 for clamping the steel ring is installed below the steel cable 23, a laser baffle 3 is provided on the base 1, the laser baffle 3 comprises a baffle 31, and a light source receiving device 32 is installed on the baffle 31;

[0024] See also Figures 1 to 3 , the steel cable 23 is perpendicular to the slide rail 6, so that the steel ring clamping 22 is on the same horizontal line with the feeding mechanism 5 during the process of clamping the steel ring, and the center point is found more quickly. Then, the steel ring clamping 22 is driven by the steel cable 23 to extend and retract. In this way, the labor cost is greatly reduced and the work efficiency is increased.

[0025] The base 1 is provided with a feeding mechanism 5 for adjusting the centering of the steel ring, and the feeding mechanism 5 includes a material transport trolley base 57 located on the base 1, a material transport trolley hydraulic device 54 is provided on the material transport trolley base 57, and a material transport trolley body 58 is provided at the output end of the material transport trolley hydraulic device 54, a marking ruler 52 is installed on one side of the material transport trolley body 58, and a hollow material transport trolley reel 59 is provided on one side of the material transport trolley body 58, a support bar hydraulic device 56 is installed inside the material transport trolley reel 59, and an anti-slip support bar 53 is provided at the output end of the support bar hydraulic device 56; The axis of the material trolley reel 59 is provided with the material transport trolley axis 51, and the material transport trolley body 58 is fixed with an anti-slip baffle 55 fixed with an auxiliary steel ring. The base 1 is provided with a slide rail 6 for the sliding of the material transport trolley base 57, and the marking ruler 52 is provided with marks for convenient observation of the size of the steel coil. A through hole with the same axis as the material transport trolley axis 51 is provided on the material transport trolley body 58, and rollers can be installed on both sides of the material transport trolley base 57 for easy sliding; the material transport trolley body 58 is more stable when sliding along the slide rail 6 with the coil, and will not shake or overturn during transportation.

[0026] An uncoiler 4 is mounted on the base 1. The uncoiler 4 includes an uncoiler power unit 44. The uncoiler power unit 44 and the baffle 31 are coaxial. A reel 42 is mounted on the uncoiler power unit 44. A laser 41 is mounted at the axis of one end of the reel 42. The laser 41 and the light source receiving device 32 are coaxial. An anti-slip strip 43 is provided on the outer side of the reel 42.

[0027] The height of the laser 41 can be adjusted according to the rising height of the steel coil, and it can be at the same horizontal height as the light source receiving device 32, and at the same height as the axis 51 of the material transport trolley; it is convenient for centering adjustment. When the laser projected by the laser 41 can illuminate the light source receiving device 32 when there is no steel coil blocking it, it means that the steel ring is in the center, and the material transport trolley body 58 can directly deliver the coil to the reel 42 along the track slide 6. In this way, the centering is more accurate, which solves the traditional manual judgment of the coiling distance with the eyes; thus, coiling is more convenient.

[0028] After the hydraulic device 54 of the material transport trolley is activated, the output end of the hydraulic device 54 aligns the laser 41 with the axis 51 of the material transport trolley and the light source receiving device 32, making it easier and safer to center the steel ring. When the hydraulic device 54 of the material transport trolley is raised to its highest position, centering is faster. Anti-skid bars 55 are provided on the body 58 of the material transport trolley. This design can better prevent the steel ring from slipping during transportation. A marking ruler 52 is provided on the body 58 of the material transport trolley. When the steel ring is fixed by the anti-skid support bar 53, the position of the mark on the marking ruler 52 can be used to visually observe the size of the steel ring to see if it meets the specified size, and better docking with the reel 42. The height of the laser 41 and the light source receiving device 32 can be adjusted according to actual working conditions.

[0029] Working principle: When centering the steel ring, first hoist it onto the material transport trolley body 58 through the steel ring clamp 22 under the hoisting bracket 21, so that the steel ring is inserted into the material transport trolley reel 59, and then start the support bar hydraulic device 56. The output end of the support bar hydraulic device 56 drives the anti-skid support bar 53 to move, so that the anti-skid support bar 53 is expanded to fix the inside of the steel ring; then start the material transport trolley hydraulic device 54. The output end of the material transport trolley hydraulic device 54 drives the material transport trolley body 58 to move upward. At the same time, the material transport trolley body 58 drives the steel ring to move upward. When the steel ring moves to a certain position, the hydraulic device 56 is started at this time. Light 41, the laser emitted by laser 41 passes through the through hole on the material transport trolley axis 51 and the material transport trolley body 58, and shines on the light source receiving device 32 on the baffle 31, thereby judging the centering of the steel ring. In addition, the hydraulic device 54 of the material transport trolley can be controlled to adjust the upper and lower positions of the steel ring, thereby adjusting the centering of the steel ring, and then drive the material transport trolley base 57 to make the material transport trolley base 57 slide on the slide rail 6. At the same time, the material transport trolley base 57 drives the steel ring on the material transport trolley body 58 to move to the reel 42, and installs the steel ring on the reel 42 to complete the installation and centering work.
