[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model achieves the effect of threading the auxiliary coiled steel strip by setting a flipping plate and oil cylinder B, so as to solve the problem that the end of the steel strip is curled by the influence of the steel coil during the rolling of existing hot-rolled steel strip, which requires manual assistance for threading and has poor threading safety.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0024] Example 1
[0025] like Figure 1-4 As shown, to achieve the above objectives, this utility model provides the following technical solution: A control device for improving the stability of hot-rolled strip threading, comprising a frame 1 and a tilting plate 3. The tilting plate 3 is installed in the middle of the frame 1 via a movable shaft 21. A positioning shaft 17 is installed near the bottom center of the frame 1. A hydraulic cylinder B18 is installed on the outer surface of the positioning shaft 17. Dovetail grooves 10 are provided on both the front and rear surfaces of the tilting plate 3. A slider 11 is installed inside the dovetail groove 10. A positioning frame 12 is installed on the top of the slider 11. Positioning wheels 13 are installed on both sides of the bottom of the positioning frame 12. An infrared sensor 2 is installed in the middle of the top of the tilting plate 3. The interior of the tilting plate 3 is located at the position of the dovetail groove 10. A rotating shaft 14 is installed at one end. A drive motor 15 is installed on the side of the rotating shaft 14 near the dovetail groove 10 via a motor frame 16. The rotating shaft 14 is sleeved inside the sliders 11 on both sides. The rotating shaft 14 and the sliders 11 are connected by a threaded connection. The threads on the outer surface of the rotating shaft 14 are reversed. The rotating shaft 14 drives the sliders 11 to move in opposite directions. A connecting seat 20 is installed in the middle of the bottom of the flip plate 3. A connecting frame 19 is installed at the output end of the hydraulic cylinder B18. The connecting seat 20 and the connecting frame 19 are connected by a positioning pin. A unwinding wheel 4 is installed inside the frame 1 near the side of the flip plate 3. Rollers 8 are installed inside the frame 1 near the top and near the bottom on the side away from the unwinding wheel 4.
[0026] The working principle of the control device for improving the stability of hot-rolled strip steel threading based on Embodiment 1 is as follows: After the utility model is installed, during use, the hot-rolled strip steel is unwound by the unwinding wheel 4 and falls onto the tilting plate 3. At the same time, the hydraulic cylinder B18 is started, which drives the tilting plate 3 to tilt and adjust the hot-rolled strip steel to a horizontal position. After the infrared sensor 2 senses the movement of the hot-rolled strip steel, the drive motor 15 is started, which drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the slider 11 to move and adjusts the positioning wheel 13 to move. The positioning wheels 13 on both sides position the hot-rolled strip steel, making it easier to thread it into the roll 8. At this point, the working process of the equipment is completed.
[0027] Example 2
[0028] like Figure 4 and Figure 5 As shown, the present invention proposes a control device to improve the stability of hot-rolled strip threading. Compared with Embodiment 1, this embodiment further includes: a fixed seat 6 installed inside the frame 1 near the top of the gap between the roll 8 and the unwinding wheel 4; a hydraulic cylinder A7 installed on the top of the fixed seat 6; an extrusion seat 5 installed on the output shaft of the hydraulic cylinder A7; a roller pressing groove 23 provided at the bottom of the extrusion seat 5; a pressure roller 22 installed at the top of the roller pressing groove 23; and roller pressing rollers 24 installed on both sides of the bottom of the pressure roller 22 inside the roller pressing groove 23. The pressure rollers 22 extrude pressure on the roller pressing rollers 24, thereby ensuring the rolling effect of the roller pressing rollers 24. There are a total of eight roller pressing rollers 24, and the eight roller pressing rollers 24 are respectively located at the bottom position inside the roller pressing groove 23. A limit rod 9 is installed on the top of the extrusion seat 5, and the limit rod 9 passes through the inside of the fixed seat 6. The limit rod 9 facilitates the movement of the extrusion seat 5.
[0029] In this embodiment, when in use, after the infrared sensor 2 senses the hot-rolled strip steel, the hydraulic cylinder A7 is activated. The hydraulic cylinder A7 drives the extrusion seat 5 to move down, thereby driving the roller 24 to move down. The roller 24 and the pressure roller 22 extrude the hot-rolled strip steel, thus flattening the hot-rolled strip steel, making it easier to pass the hot-rolled strip steel into the gap of the rolls 8.
[0030] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
