Problems solved by technology

[0007]1. The use of the anti-belt deviation device will affect the tension of the belt, so that the tension of the belt will continue to change, resulting in edge deformation or fatigue damage of the belt. Not only will it affect the service life of the belt, but the decrease in tension will cause the belt to swim back and forth in the roller system, and more serious deviations will occur, resulting in product defects such as the deflection of the belt head when the strip is threaded and the folds when the strip is coiled. ;
[0008]2. With the extension of the online use time of the belt, the function of the anti-belt deviation device will gradually become invalid. If you need to adjust the deviation of the belt, you need to stop the machine and It is difficult to adjust, and it also affects the production efficiency of the unit;
[0009]3. The structure of the anti-belt deviation device is complicated, and the requirements for the installation position are high

Embodiment 1

[0063] The device of the present invention is put into use in the outlet section of the five-cold-rolling unit finishing unit of a certain cold-rolling plant.

[0064] The utility model relates to an on-line belt adjustment device for preventing belt deviation, which is arranged at the upper and lower positions of the sides of the belt, and includes a pressure roller for exerting pressure on the belt, a pressure roller bracket part and a pressure roller angle adjustment part. The pressure wheel bracket part includes a fixed bracket and a side movable bracket that can move along the belt surface, and its pressure wheel is arranged obliquely above and below the upper and lower belts relative to the belt surface. The pressure wheel angle adjustment part is installed on the mobile bracket, and can adjust the belt pressure angle of the pressure wheel.

[0065] The fixed bracket is fixed on the basic equipment by welding, and the position of the left mobile bracket is adjusted throu...

Embodiment 2

[0075] Except for the following differences, others are the same as Example 1.

[0076] The belt on-line adjustment device for preventing belt deviation in this embodiment is used in pairs, that is, the side moving bracket that can move along the belt surface of the pressure wheel bracket part is connected with a symmetrical opposite side moving bracket, and the pair The same pressure wheels and pressure wheel angle adjustment parts are arranged symmetrically on the side moving support, so that the symmetrically arranged pressure wheels and pressure wheel angle adjustment parts on the moving support are arranged in a "V" shape.

[0077] The four sets of pressure rollers are respectively fixed on the left and right brackets, and the brackets can make the four sets of pressure rollers be symmetrically arranged on the upper and lower sides of the belt in a "V shape", and at the same time, the position can be adjusted up, down, left, and right to find out and adjust the belt deviat...

Embodiment 3

[0079] Except for the following differences, others are the same as Example 1.

[0080] The adjusting device of this embodiment is divided into left and right symmetrical structures, such as Figure 7 , the left and right symmetrical structure of the adjustment device can be symmetrically arranged on both sides of the belt, the schematic diagram of its online use is as follows Figure 11 . The integral adjustment device is generally used on narrow belts, and the adjustment device split into left and right symmetrical structures is generally used on wide belts.

[0081] The pressure roller is arranged obliquely above and below the upper and lower belts at an angle of 25-45° (β) relative to the belt surface, and the oblique wedge-shaped shaft surface is arranged obliquely at an angle (α) of 15-20° relative to the shaft centerline .

[0082] According to the belt on-line adjustment device for preventing belt deviation in the present invention, product quality problems such as ...

Abstract

A belt online adjusting device capable of preventing belt deviation comprises pinch rollers, pinch roller support components and pinch roller angle adjusting components, wherein the pinch roller support components allow the pinch rollers to be arranged above and below a belt in a symmetrical V-type manner and simultaneously execute the belt positioning from above, below, left and right. The device in the invention avoids the problems of band steel deviation, folding of band threading and piling-up of steels, which are caused by the floating movement and deviation of the belt; wedge-shaped shafts enable the pinch rollers to execute three-dimensional 360-degree adjustment and are connected with the pressboards through key slots, thereby guaranteeing the synchronized adjustments of the pinchrollers and the pressboards and accordingly improving the adjustment speed; and the pinch rollers can prevent the edge damage after the belt deviates. The device in the invention has a small request for installation positions, is capable of online change and adjustment and can be widely applied to belt conveying equipment of galvanizing machine sets or other machine sets in the industry of cold rolling.

Description

technical field [0001] The present invention relates to a conveying device for iron and steel metallurgy cold rolling galvanizing or continuous annealing unit, more precisely, the present invention relates to a belt conveying device for strip steel conveying of galvanizing or continuous annealing unit, the device can prevent the belt from running Offset and online quick adjustment of the belt position. Background technique [0002] In iron and steel metallurgical cold rolling mills, all units are basically equipped with belt conveyors, and belt conveying equipment is widely used in various units of cold rolling mills. The function of the belt conveying device is: to guide the strip head during strip threading or strip operation; At this point, the process of the belt conveyor on the unit is as follows: figure 1 shown. Wherein, 1 is a transmission motor, 2 is a driving roller, 3 is a strip steel, 4 is an idler roller, 5 is a passive roller, 6 is a passive roller adjustment...
