[0027] A lower bracket 4 is fixedly arranged between the lower ends of the two columns 1 . The lower bracket 4 is horizontally arranged along the left-right direction. The left and right ends of the lower bracket 4 are fixedly connected to the lower ends of the two columns 1 , respectively.

[0028] An upper bracket 5 is arranged above the lower bracket 4, and the upper bracket 5 is parallel to the lower bracket 4, and the upper bracket 5 is located between the left and right columns 1. A vertical rotating shaft 6 is fixedly arranged in the middle of the upper bracket 5. A rotating sleeve 7 is fixedly arranged in the middle of the lower bracket 4, and the rotating sleeve 7 is a cylindrical structure with upper and lower ends opened, and the lower end of the rotating shaft 6 is inserted into the rotating sleeve 7. The outer wall of the rotating shaft 6 and the inner wall of the rotating sleeve 7 are rotatably connected through upper and lower bearings 8. The upper bracket 5 rotates relative to the lower bracket 4 through the rotating shaft 6.

[0029] A distance sleeve 9 is sleeved on the outer side of the rotating shaft 6 between the inner rings of the upper and lower bearings 8, and the two ends of the distance sleeve 9 are in contact with the inner rings of the upper and lower bearings 8 respectively.

The left and right positions of the roller-stop bracket 22 can be adjusted through the oblong holes. The front end of the roller-stop bracket 22 is tilted upward. A roller 23 is rotatably arranged at the upper end of the roller-stop bracket 22. The axis of the roller 23 is located in a vertical plane in the left and right directions. The lower end of the roller 23 is rotatably connected to the upper end of the roller-stop bracket 22, and the upper end of the roller 23 is tilted toward the other side of the roller 23. The two rollers 23 are respectively located on the left and right sides of the adhesive tape, and the outer cylindrical surfaces of the two rollers 23 are in rolling contact with the left and right edges of the adhesive tape.

[0034] The working principle of the utility model is:

[0035] When the belt deviates, the upper bracket 5 will be driven to rotate a certain angle, and the upper bracket 5 will drive the roller group and the two stop rollers 23 to rotate synchronously. At this time, the two stop rollers 23 and the belt rotate relative to each other, and the stop roller 23 on one side is squeezed against the edge of the belt. The stop roller 23 applies a lateral thrust to the belt, forcing the belt to run in the center. After the belt is centered, it returns to the original position to achieve the deviation correction function.

[0036] The two stop rollers 23 directly prevent and limit the deviation of the tape when the tape deviates seriously, so that the tape runs in the center and the deviation adjustment effect is better. The automatic deviation correction device does not add any electrical components, has low cost, and has a significant deviation adjustment effect. It reduces the damage to the tape caused by the deviation of the tape and increases the service life of the tape.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
