AI Technical Summary
When the existing swing roller mechanism is fixed with the angle of the swing arm, the processing accuracy requirements are high and cannot be adjusted, or it is easy to loosen after being fixed with the expansion sleeve, resulting in changes in the level and parallelism of the swing roller mechanism, and the speed and tension cannot be effectively adjusted.
A swing roller swing arm adjustment and fixing device is designed, which uses the adjustment swing arm and swing arm to connect concentrically. By adjusting the rotation of the screw limit swing arm, the requirements for machining accuracy of the keyway of the rotation center axis are reduced, and the swing arm is fixed through the constraint groove and the adjustment screw to avoid loosening of the expansion sleeve.
The accuracy requirements for keyway processing of the rotating center shaft are reduced, and the mechanism failure caused by loosening of the expansion sleeve is reduced, making the swing roller mechanism more stable and able to work normally.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of industrial production, and particularly relates to a swing arm adjustment and fixing mechanism for a swing roller. Background Art
[0002] At present, the swing roller is mainly used in the winding and unwinding mechanism of pole pieces or thin films. It is an important mechanism for adjusting speed or tension. The left and right swing arms of the swing roller are generally fixed with a flat key or an expansion sleeve. However, if a flat key is used for fixing, the machining accuracy of the left and right keyways on the central rotating shaft is extremely high and cannot be adjusted. Generally, if it is detected to be unqualified after installation, the central rotating shaft can only be remade. If an expansion sleeve is used for fixing, although the expansion sleeve can adjust the angle of the left and right swing arms, after a period of use, the looseness of the expansion sleeve will cause the angle of the left and right swing arms to change, resulting in changes in the horizontality and parallelism of the swing roller mechanism, and thus the speed and tension cannot be effectively adjusted.

[0017] Below, the utility model is further described in conjunction with the accompanying drawings.
[0018] A swing roller and swing arm adjustment and fixing device comprises a swing roller, a rotation center axis, a left swing arm and a right swing arm, wherein the swing roller and the rotation center axis are arranged in parallel and are both located between the two swing arms.
[0019] Wherein, both ends of the swing roller are respectively connected to corresponding swing arm bearings; and it is characterized in that it also includes an adjustment swing arm;
[0020] The adjusting swing arm and the swing arm are concentrically connected at one end of the rotating central axis; the adjusting swing arm and the rotating central axis are fixedly connected, and the swing arm on the same side of the adjusting swing arm is connected to the rotating central axis bearing;
[0021] A constraint groove is provided on the adjustment swing arm; the swing arm is located in the constraint groove and can rotate freely in the constraint groove; adjustment screws are also provided on both sides of the adjustment swing arm, the adjustment screws are threadedly connected to the adjustment screws, and the inner ends of the two adjustment screws are against both sides of the swing arm located in the constraint groove, so as to limit the rotation of the swing arm.
[0022] The rotating central shaft and the adjusting swing arm are both provided with corresponding key slots, and the two are connected via a key located in the key slot.
[0023] The adjusting swing arm is provided with at least one.
[0024] The following is a more specific embodiment:
[0025] The function of the swing roller in this embodiment is that the cylinder drives the rotation of the rotating center shaft, so that the swing roller swings left and right to adjust the tension of the pole piece or thin film material and the stable speed. The original mechanism is that the left swing arm and the right swing arm are fixed to the rotating center shaft with a flat key, so there will be very high matching requirements for the processing of the two detections on the rotating center shaft. Once the processing error is too large, the angles of the two swing arms will be different, so that the swing roller will appear high at one end and low at the other end. Or the left swing arm and the right swing arm are fixed to the rotating center shaft with an expansion sleeve. Although this reduces the processing of the keyway on the rotating center shaft, and the expansion sleeve can adjust the angle at will, the swing roller mechanism may have an impact when working, so the expansion sleeve may become loose, which will also cause the swing roller to appear high at one end and low at another end.
[0026] like Figures 1 to 3 , an adjustment swing arm is added to this mechanism, and the adjustment swing arm, right swing arm and rotating center axis are fixed by flat keys. The left swing arm is fixed by screws and adjustment swing arm, and a rotating waist-shaped adjustment hole is processed on the left swing arm. The angle of the left swing arm can be adjusted by adjusting the top screw on the top block of the adjustment swing arm. Thus, the angles of the left and right swing arms are the same. In this way, even if the keyway processing error on the rotating center axis is large, it can be adjusted to meet the use. In addition, the left swing arm, right swing arm, adjustment swing arm and adjustment swing arm top block are all mechanically fixed structures, which have the advantages of simple adjustment, stability and not easy to fail.
