DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Embodiment 1: Please refer to Figures 1-4 , a combined type steel rolling mill guard, including a connecting seat 1 and a gear 3. The top end of the connecting seat 1 is fixedly connected with a fixed support rod 11. Both sides inside the connecting seat 1 are movably connected with mounting rods 7. Guide rollers 8 are respectively arranged at the outer tops of the mounting rods 7 and the fixed support rod 11. A driving mechanism for facilitating the simultaneous rotation of the two groups of gears 3 is arranged at the rear end inside the connecting seat 1;

[0026] The driving mechanism includes a gear 3, a rack 6 and a servo motor 14. The servo motor 14 is installed at the rear end on the right side of the connecting seat 1. The output end of the servo motor 14 is fixedly connected with a worm 5. Both sides inside the connecting seat 1 are movably connected with mounting shafts 15. The front end outside the mounting shaft 15 is fixedly connected with a gear 3. The rear end outside the mounting shaft 15 is fixedly connected with a worm gear 16. A rack 6 is arranged at the top of the gear 3;

[0027] The threads on both sides of the outside of the worm 5 are opposite. The worm 5 and the worm gear 16 cooperate with each other. The mounting rod 7 is fixedly connected to the top of the rack 6. The rack 6 and the gear 3 cooperate with each other;

[0028] Specifically, as Figure 1 and Figure 2 shown, start the servo motor 14. The servo motor 14 drives the worm gear 16 to rotate through the worm 5. The worm gear 16 drives the gear 3 to rotate through the mounting shaft 15. The gear 3 can drive the rack 6 to move left and right, so that the distance between the guide rollers 8 can be adjusted. Adjusting the distance between the guide rollers 8 can facilitate the guiding of materials of different sizes. Using the worm 5 and the worm gear 16 can drive the two groups of gears 3 to rotate simultaneously.

[0029] Embodiment 2: A support block 10 is arranged outside the mounting rod 7. A pressing block 9 is arranged at the top outside the mounting rod 7. Adjusting holes 13 are respectively opened at the rear ends inside the mounting rod 7 and the support block 10. Mounting bolts 12 are arranged inside the adjusting holes 13. The support block 10 and the pressing block 9 are respectively arranged at the bottom end and the top end of the guide roller 8. The support block 10 supports the guide roller 8. Multiple groups of adjusting holes 13 are opened. The support block 10 is respectively installed outside the mounting rod 7 and the fixed support rod 11 through the mounting bolts 12 and the adjusting holes 13;

[0030] Specifically, as Figure 1 and Figure 4 shown, the support block 10 can support the guide roller 8. When the height of the guide roller 8 needs to be adjusted, the mounting bolt 12 is screwed out from the inside of the adjusting hole 13 to make the support block 10 lose its fixation. After the support block 10 loses its fixation, the support block 10 slides outside the mounting rod 7 and the fixed support rod 11, so that the height of the guide roller 8 can be adjusted to facilitate the use of this structure in different places. The pressing block 9 can limit the guide roller 8 to prevent the guide roller 8 from accidentally detaching from the outside of the mounting rod 7 and the fixed support rod 11.

[0031] Embodiment 3: Fixed blocks 18 are respectively fixedly connected to both sides at both ends of the rack 6. The bottom end of the fixed block 18 is fixedly connected with a movable support rod 4. The bottom end of the movable support rod 4 is fixedly connected with a limit slider 17. Limit chutes 2 are respectively arranged at both ends on both sides inside the connecting seat 1. A ball 19 is arranged at the bottom end inside the limit slider 17. The limit slider 17 slides left and right inside the limit chute 2. The ball 19 rolls inside the limit slider 17;

[0032] Specifically, as Figure 1 and Figure 4 shown, when the rack 6 moves left and right, the limit slider 17 at the bottom end of the movable support rod 4 will slide left and right inside the limit chute 2. This can not only limit the rack 6 to prevent it from shifting during movement and misaligning with the gear 3, but also improve the stability of the rack 6 during movement. The ball 19 at the bottom end inside the limit slider 17 can reduce the friction between the limit slider 17 and the limit chute 2.

[0033] Working principle: When the present utility model is in use, the support block 10 can support the guide roller 8. When it is necessary to adjust the height of the guide roller 8, the mounting bolt 12 is screwed out from the inside of the adjustment hole 13 to make the support block 10 lose its fixation. After the support block 10 loses its fixation, the support block 10 slides outside the mounting rod 7 and the fixed support rod 11, so that the height of the guide roller 8 can be adjusted. After adjustment, the mounting bolt 12 is screwed into the adjustment hole 13 again to fix the support block 10. After fixation, the servo motor 14 is started. The servo motor 14 drives the worm gear 16 to rotate through the worm 5. The worm gear 16 drives the gear 3 to rotate through the mounting shaft 15. The gear 3 can drive the rack 6 to move left and right, so that the distance between the guide rollers 8 can be adjusted to guide materials of different sizes. Using the worm 5 and the worm gear 16 can drive two groups of gears 3 to rotate simultaneously. When the rack 6 moves left and right, the limit slider 17 at the bottom end of the movable support rod 4 will slide left and right inside the limit chute 2. This can not only limit the rack 6 to prevent it from shifting during movement and misaligning with the gear 3, but also improve the stability of the rack 6 during movement.
