Description

Technical Field

[0001] This utility model relates to the field of guide roller technology, specifically to an adjustable parallelism guide roller device. Background Technology

[0002] Guide rollers are core components used in industrial production to guide, support, convey, or correct continuous materials such as strips, filaments, and sheets. They are widely used in papermaking, printing, textiles, metal processing, and other fields. Their core function is to reduce material conveying resistance through their own rotation, while ensuring stable material trajectory and uniform tension, preventing material deviation, wrinkling, or damage.

[0003] During long-term use, the parallelism of the guide roller may change due to loosening, offset, or deformation of the supporting components used to fix the guide roller. Most existing guide rollers are fixed with bolts, which cannot adjust the parallelism of the guide roller. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem this invention aims to solve is that most of the guide rollers are fixed by bolts, making it impossible to adjust their parallelism.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an adjustable parallelism guide roller device, including L-shaped fixed plates arranged on both sides, bearing seats provided on the L-shaped fixed plates, guide rollers rotatably mounted on the bearing seats, a fixing mechanism provided between the bearing seats and the L-shaped fixed plates, an adjustment mechanism one for driving the bearing seats to adjust their up and down positions on one side of the L-shaped fixed plates, and an adjustment mechanism two for driving the bearing seats to adjust their front and back positions on the other side of the L-shaped fixed plates.

[0008] As an improvement, the fixing mechanism includes an L-shaped fixing plate and a sliding hole on the bearing seat, a screw is inserted into the sliding hole, and a nut is provided on the L-shaped fixing plate for threaded connection with the screw.

[0009] As an improvement, the adjustment mechanism includes a slide groove on an L-shaped fixed plate, a slider is slidably disposed in the slide groove, the slider is provided with an inclined surface, the inclined surface is in contact with the side of the bearing seat, and a screw rod is threadedly connected to the L-shaped fixed plate, which passes through the slide groove, and the slider is rotatably disposed on the screw rod.

[0010] As an improvement, the second adjustment mechanism includes a second slide groove on an L-shaped fixed plate, a second slider is slidably disposed in the second slide groove, a connecting plate is disposed on the second slider, the connecting plate is fixedly connected to the bearing seat by bolts, and a second screw rod is rotatably disposed in the second slide groove to drive the second slider to slide, the second screw rod being threadedly connected to the second slider.

[0011] As an improvement, an anti-slip pad is provided between the nut and the L-shaped fixing plate.

[0012] (III) Beneficial Effects

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] By setting a fixing mechanism, the bearing housing can be fixed while accommodating subsequent adjustments to the bearing housing in terms of height and direction. By setting an adjustment mechanism one, when the parallelism of the guide roller changes, the guide roller can be leveled by adjusting the height of the guide roller axis, or the horizontal angle of the axis can be adjusted by adjusting the front and rear position of the guide roller to make the guide roller level.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] As per the instructions Figures 1 to 3As shown, an adjustable parallelism guide roller device includes L-shaped fixed plates 1 arranged on both sides. A bearing seat 2 is provided on the L-shaped fixed plate 1, and a guide roller 3 is rotatably mounted on the bearing seat 2. A fixing mechanism 4 is provided between the bearing seat 2 and the L-shaped fixed plate 1. An adjustment mechanism 5 is provided on one side of the L-shaped fixed plate 1 to drive the bearing seat 2 to adjust its up and down position, and an adjustment mechanism 6 is provided on the other side of the L-shaped fixed plate 1 to drive the bearing seat 2 to adjust its front and back position.

[0022] When the parallelism of the guide roller 3 changes, it will affect the product and cause problems such as wrinkles on the product surface. At this time, the fixing mechanism 4 releases the fixing of the bearing seat 2. Then, the adjustment position is determined according to whether the axis of the guide roller 3 is offset vertically or horizontally. When it is offset vertically, the guide roller 3 is leveled by the first adjustment mechanism 5. When it is offset horizontally, the guide roller is leveled by the second adjustment mechanism 6. Then, the fixed mechanism 4 fixes the adjusted bearing seat 2.

[0023] As per the instructions Figures 2 to 4 As shown, the fixing mechanism 4 includes an L-shaped fixing plate 1 and a sliding hole 7 on the bearing seat 2. A screw 8 is inserted into the sliding hole 7. The L-shaped fixing plate 1 is provided with a nut 9 that is threadedly connected to the screw 8. An anti-slip pad is provided between the nut 9 and the L-shaped fixing plate 1. In order to adapt to vertical and horizontal adjustment, the sliding hole 7, screw 8 and nut are provided so as to adapt to changes in height and position after adjustment. The anti-slip pad can assist in fixing and prevent the nut 9 from slipping.

[0024] The adjustment mechanism 5 includes a slide groove 10 on an L-shaped fixed plate 1. A slider 14 is slidably disposed in the slide groove 10. The slider 14 is provided with an inclined surface 11, which is in contact with the side of the bearing seat 2. A screw 12 is threadedly connected to the L-shaped fixed plate 1, which passes through the slide groove 10. The slider 14 is rotatably disposed on the screw 12. When the screw 12 is rotated, the screw 12 moves in the slide groove 10 while rotating, and drives the slider 14 to slide in the slide groove 10. The inclined surface 11 lifts the bearing seat 2, thereby changing the height of the bearing seat 2 to adjust the parallelism.

[0025] The second adjustment mechanism 6 includes a second groove 13 on an L-shaped fixed plate 1. A second slider 17 is slidably disposed in the second groove 13. A connecting plate 15 is disposed on the second slider 17. The connecting plate 15 is fixedly connected to the bearing seat 2 by bolts. A second screw 16 is rotatably disposed in the second groove 13 to drive the second slider 17 to slide. The second screw 16 is threadedly connected to the second slider 17. When the second screw 16 is rotated, the second screw 16 drives the connecting plate 15, and the connecting plate 15 drives the bearing seat 2 to slide, thereby adjusting the parallelism by changing the horizontal position of the bearing seat 2.

[0026] In practical use, the L-shaped fixing plate 1 is fixedly connected to the equipment. When the parallelism of the guide roller 3 changes, the first situation is that the axis of the guide roller 3 changes vertically. At this time, the position of the inclined plane 11 is adjusted by rotating the screw 12 to adjust the height of the bearing seat 2 so that the axis is horizontal. The second situation is that the axis of the guide roller 3 changes front to back. At this time, the position of the connecting plate 15 is adjusted by rotating the screw 16, thereby adjusting the front to back position of the bearing seat 2 so that the axis is horizontal.
