Detailed Description

The following description of the embodiments of the present utility model will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model. The technical features of the different embodiments of the utility model described below may be combined with one another as long as they do not conflict with one another.

Referring to fig. 1, the guide device in this example includes a base 1, two sides of the upper end of the base 1 are provided with supporting arms 2, the supporting arms 2 on two sides are provided with a front guide roller 3 and a rear guide roller 4, the front guide roller 3 and the rear guide roller 4 on two sides are respectively and correspondingly arranged, the front guide roller 3 on two sides form a front guide roller group, the rear guide roller 4 on two sides form a rear guide roller group, the front guide roller group and the rear guide roller group define a steel channel, the front guide roller 3 and the rear guide roller 4 are respectively arranged at the middle part and the outlet end of the steel channel, and thus, the steel entering the steel channel is guided by the front guide roller group and the rear guide roller group and is smoothly in the pre-finishing mill group.

The positions of the front guide roller and the rear guide roller can be adjusted by adjusting the heights of the support arms 2 at two sides to ensure the centering of the front guide roller and the rear guide roller, but the adjustment of the support arms 2 is the integral adjustment, the front guide roller is more convenient to adjust at the outlet end of the steel channel, the disassembly and the reinstallation are more convenient, the independent adjustment of the rear guide roller 4 is more difficult if the rear guide roller 4 is wanted, the rear guide roller 4 comprises a roller shaft 41 and a roller 42 arranged on the roller shaft 41, the roller shaft 41 is an eccentric guide roller shaft, a through groove 21 is further arranged in the support arm 2, the roller 42 is positioned in the through groove 21, one end of the guide shaft is provided with a worm wheel 43, the worm wheel 43 extends to the upper end of the support arm 2, the upper end of the worm wheel 43 is provided with a dust cover 12, the dust cover 12 is internally provided with the bearing and the worm 13, the bearing is sleeved on the roller shaft 41, the worm 13 is in contact with the worm wheel 43 and is matched with the worm wheel, the worm wheel 43 can rotate when the worm 13 is driven, the roller shaft 41 is driven to rotate when the worm wheel 43 rotates, the distance between two guide rollers in the rear guide wheel set, namely the opening degree, can be adjusted because the roller shaft 41 is an eccentric guide roller shaft, one end of the worm 13 penetrates through the dust cover 12 and is processed into a hexagon, thus the worm 13 can be rotated through an open spanner, the roller shaft 41 is driven to axially rotate through the worm wheel 43 matched with the worm 13, and the distance between the two guide rollers in the rear guide wheel set, namely the opening degree, can be adjusted without opening the dust cover 12.

As shown in fig. 3, the other end of the roller shaft is further provided with a threaded structure, the threaded structure penetrates through the lower end of the supporting arm 2, a nut 44 matched with the threaded structure is further arranged on the threaded structure, a disc spring 45 is further arranged between the lower end of the roller 42 and the threaded structure, the disc spring 45 is of an elastic structure, and one end of the guide shaft is fixed by the dust cover 12. During the screwing of the nut 44, the roller shaft 41 moves downward in the axial direction, and the roller 4 mounted on the roller shaft 41 is driven to press the disc spring 45. Due to the characteristics of the disc spring, the disc spring can deform after being extruded, so that the disc spring becomes flatter, and the disc spring can gradually recover under the action of self elasticity along with the release of pressure after the pressure is released. Therefore, as the nut 44 is screwed, the disc spring 45 is deformed slowly in a certain stroke by the pressing force, so that the roller 4 mounted on the roller shaft 41 is moved in the axial direction; when the nut 44 is unscrewed, the disc spring gradually returns the roller 4 supported on the roller shaft 41 to the state before the nut 44 is screwed down under the elastic action of the disc spring, thereby realizing the reciprocating micro-adjustment of the roller 4 mounted on the roller shaft 41 in the axial direction. The rear guide roller is not required to be detached and reinstalled.

The inlet end of the steel channel is also provided with an adjusting rod 5, two ends of the adjusting rod 5 are connected to the supporting arms 2 on two sides, and the adjusting rod 5 is in threaded connection with the supporting arms 2, so that the distance between the supporting arms 2 on two sides can be adjusted through rotation of threads, and the opening degree between guide wheels can be adjusted.

The top of support arm 2 still is provided with regulating block 11, regulating block 11 is connected with base 1, all be equipped with vertical direction's pin 15 in regulating block 11 and the base 1, be provided with on the support arm 2 with pin 14 assorted pinhole, also be provided with blind hole 6 in regulating block 11 and the base 1, pin 14 is located the pinhole, be provided with hexagonal end cap 15 in the pinhole, simultaneously with pin 14 outwards crowded in the pinhole when hexagonal end cap 15 moves to the pinhole for pin 14 moves to blind hole 6 department, thereby makes support arm 2 have a trace removal in vertical, and support arm 2 trace removal just can adjust holistic centering.

When the device is particularly used, after all the structures are assembled, wires enter and exit from the steel channel, and in the installation process, through the micro adjustment of the tightness degree of the locking nuts 46 of the rear guide roller 4 groups, the micro difference brought by the two groups of guide rollers in the installation process can be eliminated, and the adjustment time of guide roller pairs is reduced.

The above embodiments are only for illustrating the technical concept and features of the present utility model, and are intended to enable those skilled in the art to understand the present utility model and to implement the same, but are not intended to limit the scope of the present utility model, and all equivalent changes or modifications made according to the spirit of the present utility model should be included in the scope of the present utility model.
