As shown in fig. 1 and 2, the vertical guide roller device comprises a bottom plate 11, a vertical plate 12, a top plate 13, a fixed guide roller 21 and a movable guide roller 22. The top plate 13 is vertically and fixedly connected above the vertical plate 12 through screws, and the bottom plate 11 is vertically and fixedly connected below the vertical plate 12 through screws. The fixed guide roller 21 and the movable guide roller 22 are parallel to each other and are both provided between the top plate 13 and the bottom plate 11. Specifically, the upper end of the vertical rotation shaft 211 of the fixed guide roller 21 is fixed to the top plate 13 by a screw, the lower end of the vertical rotation shaft 211 of the fixed guide roller 21 is fixed to the bottom plate 11 by a screw, and the fixed guide roller 21 is rotatable about the rotation shaft 211. There are two fixed guide rollers 21, and the movable guide rollers 22 are in one-to-one correspondence with the fixed guide rollers 21. The upper end of a rotating shaft 221 of the movable guide roller 22 is fixedly connected with an upper slide block 14 on the top plate 13 through a screw, the lower end of the rotating shaft 221 of the movable guide roller 22 is fixedly connected with a lower slide block 18 on the bottom plate 11 through a screw, and the sliding directions of the upper slide block 14 and the lower slide block 18 are perpendicular to the fixed guide roller 21. The vertical plate 12 is respectively screwed with adjusting screws 17 from top to bottom, the inner end of each adjusting screw 17 is inserted into a T-shaped end 16, a horizontal pressure spring 15 is respectively arranged between the T-shaped end 16 and the upper slide block 14 and between the T-shaped end 16 and the lower slide block 18, one end of the upper horizontal pressure spring 15 abuts against the upper slide block 14, the other end abuts against the upper T-shaped end 16, one end of the lower horizontal pressure spring 15 abuts against the lower slide block 18, and the other end abuts against the lower T-shaped end 16. Two horizontal compression springs 15 are used to provide a clamping force between the movable guide roller 22 and the fixed guide roller 21. When the clamping force needs to be lifted, the adjusting screw 17 is screwed into the fixed guide roller 21, the T-shaped end 16 further compresses the horizontal pressure spring 15, the pressure of the horizontal pressure spring 15 on the movable guide roller 22 is increased, and then the clamping force of the movable guide roller 22 and the fixed guide roller 21 is lifted. Conversely, the adjusting screw 17 is reversely screwed out, the compression of the horizontal compression spring 15 is reduced by the T-shaped end 16, and the pressure of the horizontal compression spring 15 on the movable guide roller 21 is reduced, so that the clamping force of the movable guide roller 22 and the fixed guide roller 21 is reduced.

Therefore, the vertical guide roller device can adjust the clamping force between the movable guide roller 22 and the fixed guide roller 21 according to actual requirements when corresponding to the material strips with different thicknesses, so as to meet the winding and unwinding requirements, avoid the adverse effect caused by insufficient or overlarge clamping force, and improve the winding and unwinding efficiency and stability.

As shown in fig. 2 and 3, the vertical guide roller device further comprises a base 19, and the bottom plate 11 is disposed above the base 19. Two shaft seats 31 are arranged on the base 19, and a horizontal shaft 32 penetrates through the two shaft seats 31. In the feed direction a, the rear side of the base plate 11 is rotatably connected to the horizontal shaft 32, and the front side of the base plate 11 is connected to the base 19 via the horizontal adjustment mechanism 40.

Specifically, the base plate 11 is fixed with two connection lugs 33 by screws, the horizontal shafts 32 penetrate the connection lugs 33, respectively, and a shaft sleeve 34 is provided between the horizontal shafts 32 and the connection lugs 33.

Specifically, as shown in fig. 3, the horizontal adjustment mechanism 40 includes a vertical adjustment bolt 41, an adjustment nut 42, a spacer 43, and a vertical compression spring 44. The bottom of the adjusting bolt 41 is screwed into the base 19, and the adjusting bolt 41 penetrates the bottom plate 11, the cushion block 43 and the vertical compression spring 44 in order. The top surface of the cushion block 43 is closely attached to the lower surface of the bottom plate 11. The top of the vertical compression spring 44 abuts against the cushion block 43, and the bottom of the vertical compression spring 44 abuts against the base 19. The adjustment nut 42 is screwed from above the adjustment bolt 41 and the lower surface of the adjustment nut 42 abuts against the upper surface of the base plate 11. As the adjustment nut 42 is tightened, the side of the base plate 11 gradually compresses the vertical compression spring 44 further downward. When the adjusting nut 42 is unscrewed upwards, the vertical compression spring 44 pushes the pressure plate 11 upwards on this side. Therefore, the levelness of the bottom plate 11 can be adjusted by rotating the adjusting nut 42, so that the whole vertical guide roller device has good flatness assurance.
