Description

Technical Field

[0001] The utility model relates to the technical field of steel strip production, in particular to a centering indicator for coiling. Background Art

[0002] In the finishing process, in the production of ultra-thin steel strips, according to the process, the inner core of the exported coiled steel coil needs to be pre-installed with a steel lining copper sleeve. Then the steel strip is wrapped around the sleeve, and the steel sleeve copper supports the inner core of the entire steel coil to prevent quality problems such as core explosion and coil stepping.

[0003] However, the steel copper sleeve is installed on the coiler, and the center line of the steel copper sleeve needs to be aligned with the center point of the center line of the stand roll shaft. The steel strip is wrapped around the copper sleeve, and the width of the copper sleeve is slightly larger than the width of the steel strip. The center point of the steel strip needs to be sewn with the center line of the copper sleeve and the remaining amount on both sides of the copper sleeve is equal. If the center of the steel strip is not aligned with the rolling axis when wrapped, tension will be skewed during the production process, causing the steel strip head to deform, and easily causing quality problems such as wrinkling of the inner core. Utility Model Content

[0004] In response to the defects in the existing technology, the purpose of this utility model is to provide a centering indicator for winding, which can automatically calibrate the width of the steel strip and issue an alarm when the steel strip is not wound correctly, thereby avoiding the quality problem of inner core wrinkling caused by improper winding of the steel strip and improving production efficiency.

[0028] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0029] Example 1

[0030] Combine Figures 1 to 4As shown, an embodiment of the present invention discloses a winding centering indicator, comprising a fixed slide 1, two motors 2, two screws 3, two sliders 4, two laser generators 5 and two laser receivers; wherein, a slide rail is formed on the fixed slide 1; the two motors 2 are arranged at both ends of the fixed slide 1 relative to each other along the extension direction of the slide rail; the two screws 3 are coaxially fixedly connected to the output ends of the two motors 2, and the ends of the two screws 3 facing away from the connected motors 2 are rotatably connected to the middle of the fixed slide 1; the two sliders 4 are respectively screwed on the two screws 3, and both sliders 4 can be slidably mounted on the slide rail; the two laser generators 5 are respectively mounted on the two sliders 4; the two laser receivers are respectively arranged opposite to the two laser generators 5, for receiving the lasers emitted by the laser generators 5. The winding centering indicator of this embodiment ensures that the laser generator 5 can accurately perform centering detection along the center line of the steel strip winding through the coordinated work of the slide rail formed by the fixed slide 1 and the two screws 3 driven by the two motors 2 arranged at both ends of the slide rail, as well as the slider 4. When the slider 4 moves on the screw rod 3, the laser generator 5 installed thereon will emit a laser. The positions of the two laser generators 5 can be adjusted to both sides of the steel strip according to the width of the steel strip. The laser emitted by the laser generator 5 passes through the edge of the steel strip, and the relatively arranged laser receiver will receive these laser signals, thereby monitoring the alignment of the center line of the steel strip and the center line of the copper sleeve in real time. Once the center of the steel strip deviates from the rolling axis, the laser will be blocked, and an alarm will be issued when the laser receiver signal is disconnected, which can remind on-site staff to avoid tension problems caused by the deviation of the center of the steel strip from the rolling axis, effectively prevent the occurrence of quality problems such as deformation of the steel strip head and wrinkling of the inner core, and ensure that the steel strip in the production process can maintain a good alignment state and quality stability.

[0031] Furthermore, the fixed slide 1 of this embodiment includes two fixed assemblies that are docked with each other. Each fixed assembly includes two fixed blocks 6 and a slide rod 7. The two fixed blocks 6 are arranged opposite each other, and the slide rod 7 is fixedly connected between the two fixed blocks 6 to form a slide rail. The motor 2 is fixedly mounted on one fixed block 6, and a rotating shaft seat is mounted on the other fixed block 6. One end of the screw rod 3 is fixedly connected to the output end of the motor 2, and the other end of the screw rod 3 is rotatably connected to the rotating shaft seat. The fixed blocks 6 of the two fixed assemblies with the rotating shaft seat are connected. The fixed slide 1 is composed of two docked fixed assemblies, each including two fixed blocks 6 and a connected slide rod 7, forming a continuous slide rail, ensuring the precise sliding of the slider 4 on the slide rail. The motor 2 is fixedly mounted on one fixed block 6, and its output end drives the screw rod 3 to rotate. The screw rod 3 at the other end rotates the rotating shaft seat connected to the other fixed block 6, ensuring the stable movement of the slider 4 on the screw rod 3, thereby driving the laser generator 5 to move precisely along the slide rail.

[0032] Furthermore, the slider 4 of this embodiment is formed with a connecting sleeve, which is slidably mounted on the slide rod 7. The fixed assembly includes two slide rods 7, which are arranged side by side in parallel. Each slider 4 is formed with two connecting sleeves, which are slidably mounted on the two slide rods 7. The connecting sleeves provided on the slider 4, which are respectively mounted on the two parallel slide rods 7, enable the slider 4 to achieve precise and smooth linear sliding in the entire system, thereby achieving efficient positioning and motion control.

[0033] Furthermore, the fixing assembly of this embodiment includes a support rod 9, which is arranged parallel to the slide rod 7. The fixing block 6 is formed with a support hole 8, into which the support rod 9 is inserted. Both the support rod 9 and the support hole 8 have rectangular cross-sections. The support rod 9 provides stable support for the fixing assembly, enhancing the overall structural strength and durability of the assembly, improving the reliability and safety of the equipment's operation, and facilitating the adjustment and fixing of the remaining components.

[0034] Furthermore, the laser generator 5 of this embodiment is rotatably connected to the slider 4 via a spherical universal connector 10. This allows the laser generator 5 to be flexibly adjusted in angle and moved in position, thereby allowing for more precise alignment with a target or adapting to different application scenarios, thereby improving the flexibility and accuracy of the laser generator 5.

[0035] Furthermore, a pressure sensor 11 is installed on the end face of the slider 4 facing the motor 2 in this embodiment, which can monitor the pressure changes between the slider 4 and the motor 2 in real time, thereby realizing precise control of the movement of the slider 4, ensuring that the contact between the slider 4 and the motor 2 can be detected in time after reaching the end point of the movement, effectively preventing equipment damage caused by excessive pressure, and improving equipment safety.
