Description

Technical Field

[0001] The utility model relates to the field of belt transmission, in particular to a deviation-adjusting roller frame device. Background Art

[0002] In the prior art, due to local unevenness of the frame, the belt will deviate to a lower position during transmission. Therefore, it needs to be corrected by a correction device to avoid accidents. The existing correction solution is to set a horizontally rotatable movable belt roller frame between two fixed belt rollers. When the belt deviates, the belt twisting bracket can be twisted back and forth to apply a pulling force to the belt to finally correct it. However, in actual use, the above correction solution can only be effective temporarily. After a period of time, the belt will deviate again and need to be corrected again. If the deviation problem needs to be fundamentally solved, the frame needs to be reinstalled and adjusted, but there is no guarantee whether new unevenness defects will occur in other positions.

[0003] Therefore, designing a deviation-correcting device that can fundamentally solve the rising problem is a problem that needs to be solved at present. Summary of the Invention

[0004] In view of the above problems, the present invention provides a belt deviation correction device with good deviation correction effect and low cost. The specific solution is as follows:

[0005] A deflection adjustment roller frame device includes a base, a first roller bracket is fixedly arranged on the base, two second roller brackets are respectively provided on both sides of the first roller bracket, and the two second roller brackets and the first roller bracket together form a U-shaped groove for placing the belt, wherein:

[0006] One end of each of the two second roller supports adjacent to the first roller support is rotatably connected to the base, so that the angle between the second roller support and the first roller support can be adjusted accordingly according to the offset amplitude of the belt in the U-shaped groove to offset the inclined tension of the belt at the offset position;

[0007] The other ends of the two second roller supports are each provided with a fixing mechanism for fixing the second roller supports after the angles of the second roller supports are adjusted.

[0008] Furthermore, the first roller bracket is provided with a horizontally arranged first roller, and the second roller bracket is provided with a second roller with the same inclination angle as the first roller bracket.

[0009] Furthermore, first fixed supports are respectively provided at both ends of the first roller bracket, the bottom of the first fixed support is welded and fixed to the base, and the top of the first fixed support is hinged to the second roller bracket.

[0010] Furthermore, the fixing mechanism includes:

[0011] A second fixed support is located at the outer end of the second roller bracket and is aligned with the first fixed support. The bottom of the second fixed support is welded to the base and the top is hinged with an angle adjustment frame.

[0012] The angle adjustment frame includes a connecting rod, which corresponds to the side of the second roller bracket. The connecting rod is provided with a plurality of angle adjustment holes arranged in sequence along its length direction. The plurality of angle adjustment holes can be plugged and fixed with the screws on the side of the second roller bracket. The second roller bracket is connected to the angle adjustment holes at different heights to determine the angle formed by it and the first roller bracket.

[0013] Furthermore, the angle formed by the second roller support and the first roller support is in the range of 100° to 160°.

[0014] Furthermore, the angle adjustment frame includes two parallel connecting rods, the bottoms of the two connecting rods are hinged to the second fixed support, and the two connecting rods correspond to the two side positions of the second roller bracket respectively, and the two connecting rods are respectively provided with a plurality of the angle adjustment holes, and the multiple angle adjustment holes on the two connecting rods are aligned with each other, and the two sides of the second roller bracket are respectively provided with screws plugged into the angle adjustment holes.

[0015] Compared with the prior art, the advantages of the present invention are as follows:

[0016] 1. The utility model improves the structure of the original belt transmission roller so that the angle formed by the two second roller supports on both sides of the first roller support and the first roller support can be adjusted, so that the inclined tension applied to the belt at the offset position is offset, thereby avoiding the occurrence of the belt deviation at this position again.

[0025] like Figure 1 As shown, a deviation adjustment roller frame device includes a base, a first roller bracket is fixedly provided on the base, two second roller brackets are respectively provided on both sides of the first roller bracket, namely the second roller bracket I and the second roller bracket II, the two second roller brackets and the first roller bracket together form a U-shaped groove structure for the belt to pass through, the first roller bracket is provided with a horizontally arranged first roller, and the second roller bracket is provided with a second roller with an inclination angle consistent with the first roller bracket, wherein,

[0026] One end of the two second roller supports adjacent to the first roller support is rotatably connected to the base, so that the angle between the second roller support and the first roller support can be adjusted accordingly according to the offset amplitude of the belt in the U-shaped groove to offset the inclined tension exerted on the belt at the offset position. A first fixed support is respectively provided at both ends of the first roller support, the bottom of the first fixed support is welded and fixed to the base, and the top of the first fixed support is hinged to the second roller support.

[0027] The other ends of the two second roller supports are each provided with a fixing mechanism for fixing the second roller supports after the angles are adjusted. The fixing mechanism includes:

[0028] A second fixed support is located at the outer end of the second roller bracket and is aligned with the first fixed support. The bottom of the second fixed support is welded to the base and the top is hinged with an angle adjustment frame.

[0029] The angle adjustment frame includes a connecting rod, which corresponds to the side of the second roller bracket. The connecting rod is provided with a plurality of angle adjustment holes arranged in sequence along its length direction. The plurality of angle adjustment holes can be plugged and fixed with the screws on the side of the second roller bracket. The second roller bracket is connected to the angle adjustment holes at different heights to determine the angle formed by it and the first roller bracket. The angle formed by the second roller bracket and the first roller bracket ranges from 100° to 160°. Example

[0030] The angle adjustment frame includes two parallel connecting rods, the bottoms of the two connecting rods are hinged to the second fixed support, and the two connecting rods correspond to the positions on both sides of the second roller bracket respectively. The two connecting rods are respectively provided with a plurality of the angle adjustment holes, and the multiple angle adjustment holes on the two connecting rods are aligned with each other, and the two sides of the second roller bracket are respectively provided with screws plugged into the angle adjustment holes. Example

[0031] like Figure 1 As shown, the correction plan is as follows:

[0032] S1. When the belt deviates to the second roller support I, it means that one side of the second roller support I at this position of the frame is too low. Therefore, according to the degree of belt deviation, the angle between the second roller support II and the first roller support is increased to lower the height of the outer end of the second roller support II, and the second roller support I is fixed through the angle adjustment hole;

[0033] S2. Separate the second roller support I from the corresponding angle adjustment frame and repeatedly lift the second roller support I with a lever or crowbar to return the belt to the center position.

[0034] S3. Re-connect the outer end of the second roller bracket I to the top of the corresponding angle adjustment bracket.

[0035] As the angle between the second roller support II and the first roller support increases, the belt is subjected to a force acting toward the second roller support II, which is used to offset the inclined pulling force of the belt toward the second roller support I at this point, so that the force of the belt is kept balanced during subsequent transmission, thereby avoiding the belt from deviating again at this point.
