[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: an adjustable track for automatic paper conveying, including a first fixed frame 1 and a second fixed frame 6. A protective cover 3, which is a gusseted cover, is fixedly connected to the inner side of the first fixed frame 1. One end of the protective cover 3 is fixedly connected to the outer wall of the adjusting frame 4. This protective cover 3 can prevent dust from entering the gap between the first fixed frame 1 and the adjusting frame 4. The adjusting frame 4 is slidably connected to the conveying roller 7. The adjusting frame 4 has multiple through holes, which correspond to the positions of the conveying roller 7. This adjusting frame 4 can be positioned at different locations on the conveying roller 7 by lateral movement, thereby adjusting the length of the conveying roller 7. The purpose is to fix a support spring 8 and a sleeve 9 to the inner wall of the through hole of the adjusting frame 4. The sleeve 9 is inserted into the inner side of the support spring 8. This structure of sleeve 9 and telescopic rod 10 can limit the support spring 8, thereby ensuring the stability of the support spring 8 during the extension and retraction process and avoiding excessive deformation of the support spring 8 during the extension and retraction process. One end of the sleeve 9 is inserted with the telescopic rod 10, and one end of the telescopic rod 10 is fixedly connected to the support wheel frame 12. One end of the support spring 8 is also fixedly connected to the support wheel frame 12. This structure of support spring 8 can support the support wheel frame 12 to fit tightly against the outer wall of the conveyor roller shaft 7. The support wheel frame 12 is composed of a shaft seat, a frame body, and a wheel body. The wheel body fits against the conveyor roller shaft 7. On the outer wall of the conveyor roller 7, the support wheel frame 12 of this structure can be tightly supported on the outer wall of the conveyor roller 7. It can also rotate via the bearing seat, facilitating switching from a transverse to a longitudinal position without affecting the rotation of the conveyor roller 7. The structure of the support wheel frame 12 is similar to that of existing casters. An isolation plate 11 is fixedly connected to the inner wall of the through hole of the adjusting frame 4. The isolation plate 11 is made of rubber, which will not scratch the conveyor roller 7. The isolation plate 11 has a circular structure, and its inner side is attached to the outer wall of the conveyor roller 7. This structure allows the isolation plate 11 to fit snugly against the outer wall of the conveyor roller 7, thereby reducing the gap between the adjusting frame 4 and the conveyor roller 7 and preventing debris from entering. The material enters the interior of the adjusting frame 4 through the gap. A conveying roller shaft 7 is rotatably connected between the first fixed frame 1 and the second fixed frame 6. A drive motor 5 is provided on one side of the second fixed frame 6. One end of the shaft of the drive motor 5 is connected to the conveying roller shaft 7. The shaft of the drive motor 5 and the shaft of the conveying roller shaft 7 are connected by a sprocket and a chain. This part is existing technology, so it will not be described in detail here. The adjusting frame 4 is sleeved on the outer wall of the conveying roller shaft 7. An electric cylinder 2 is fixedly connected to one side of the first fixed frame 1. One end of the electric cylinder 2 is connected to the adjusting frame 4. The adjusting frame 4 is located inside the first fixed frame 1. The electric cylinder 2 of this structure can push the adjusting frame 4 to move laterally. Multiple electric cylinders 2 can be controlled by a PLC.

[0019] Working principle: When using this adjustable track for automatic paper conveying, if the length of the conveyor roller 7 needs to be adjusted, it can be adjusted according to the length of the paper. During the adjustment process, the electric cylinder 2 drives the adjustment frame 4 to move laterally on the outer wall of the conveyor roller 7. During the movement of the adjustment frame 4, the support wheel frame 12 on the inner wall of the through hole of the adjustment frame 4 moves on the outer wall of the conveyor roller 7. When the adjustment frame 4 is in the appropriate position, the electric cylinder 2 is closed. At this time, the length of the conveyor roller 7 reserved between the adjustment frame 4 and the second fixed frame 6 meets the usage requirements. During the use of this device, the drive motor 5 drives the conveyor roller 7 to rotate, and then the paper can be placed on the top of the conveyor roller 7 for conveying.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
