[0026] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0027] like Figure 1-Figure 9 As shown, the working principle of a device for preventing the coiled steel coil from being scratched by the strip threading is as follows: the roller group 2 is arranged below the strip threading guide plate 1, and the top of the roller surface of the roller 22 of the roller group 2 is higher than the strip threading guide plate 1. During the strip threading process of the steel coil, the steel coil plate surface passes on the roller surface of the roller 22, and rolling friction is realized instead of sliding friction, which successfully reduces the friction resistance and prevents the steel coil plate surface from sliding on the strip threading guide plate 1 and scratching the steel coil plate surface. The guide surface 14 and the guide plate 15 of the strip threading guide plate 1 realize a reliable strip threading guiding effect, and the steel coil plate head is efficiently and quickly introduced into the reel and the winder belt, which greatly improves the yield rate and the production efficiency of the unit.

[0028] like Figure 1-Figure 9The device for preventing the coiled steel coil from being scratched by the belt comprises a roller group 2, the roller group 2 is evenly arranged on the upper surface of the bottom beam 41 of the support frame 4, the side beams 42 are arranged around the bottom beam 41, the support beam 43 is arranged on the bottom beam 41, and the bottom surface of the side beam 42 is arranged on the bottom plate 44, the support beam 43 is arranged on the belt guide plate 1, the belt guide plate 1 is arranged with a screw hole 12, and the screw hole 12 is arranged with a screw 3 to connect the belt guide plate 1 with the support frame 4, and the support beam 43 is arranged in a row of roller groups 2 On both sides, the supporting force of the belt threading guide plate 1 at the position of the roller group 2 is strengthened to improve the supporting strength of the roller group 2. The top of the roller surface of the roller group 2 passes through the roller hole 13 on the belt threading guide plate 1 and is higher than the upper surface of the belt threading guide plate 1. During the process of winding the steel coil and threading the belt, the steel coil plate surface needs to pass through the belt threading guide plate 1. The original belt threading guide plate 1 uses a liner made of bakelite. The steel coil plate surface will be scratched during the sliding process of the steel coil passing through the bakelite liner. Severe scratches will cause steel piling and jamming during the process of winding the steel coil. The steel coil is transmitted by the roller surface of the roller wheel 22 which is higher than the upper surface of the threading guide plate 1, and the original sliding friction in the threading process of the steel coil is changed into rolling friction. The reduced friction can effectively avoid scratches on the steel coil surface and improve the winding efficiency. The guide surface 14 is arranged on the inlet side 17 of the threading guide plate 1, and two symmetrical guide plates 15 are arranged on the outlet side 18 of the threading guide plate 1. The guide plates 15 are arranged in a front wide and rear narrow manner along the guide direction 19 of the coiled steel coil. A guide roller 16 is arranged on the inner side of the guide plate 15. The threading guide plate 1 It is responsible for introducing the steel coil head into the coiler. Before the steel coil head enters the coiler, the guide surface 14 on the threading guide plate 1 guides the direction of the steel coil head. The guide plate 15 aligns the steel coil head with the reel of the coiler, making it easier to introduce the steel coil head into the reel and the coiler belt, thereby improving the coiling quality and coiling efficiency. A guide roller 16 is arranged on the inner side of the guide plate 15 to prevent the guide plate 15 from colliding with the steel coil head during the adjustment of the centering, so as to avoid damage to the plate head affecting the threading of the steel coil.

[0029] like Figure 7 , 8 As shown in FIG. 9 , further, the roller assembly 21 is composed of a base 211 , a roller 212 , a limiting shaft 213 , a locking nut 214 and a rotating shaft 215 .

[0030] like Figure 4 As shown, further, the screw holes 12 and the roller holes 13 are evenly distributed on the belt threading guide plate 1, the positioning through hole 11 is the connection positioning between the belt threading guide plate 1 and the support frame 4, the screw holes 12 are evenly distributed in rows on the belt threading guide plate 1, the screws 3 in the screw holes 12 connect the belt threading guide plate 1 to the support beam 43 of the support frame 4, and the belt threading guide plate 1 is provided with a roller hole 13 through which the roller 22 passes.

[0031] like Figure 6As shown, further, the screw hole 12 is a countersunk hole, and the screw 3 is embedded in the screw hole 12 to prevent the head of the screw 3 from protruding above the upper surface of the belt guide plate 1 and scratching the surface of the steel coil.

[0032] Furthermore, the roller surface of the guide roller 16 is made of PVC material, which has good elasticity, good wear resistance and strong corrosion resistance.
