Example (b):

as shown in fig. 1, the utility model provides an unreel conveying roller of rectifying, including frame 1, pivot 2 and conveying roller 3. The rotating shaft 2 is arranged on the frame 1, so that the rotating shaft 2 is supported by the bracket, and the conveying roller 3 is further supported. The conveying roller 3 is sleeved on the rotating shaft 2. The specific inner diameter of the feed roller 3 is larger than the outer diameter of the rotary shaft 2, so that the feed roller 3 can not only rotate relative to the rotary shaft 2 but also slide relative to the rotary shaft 2. The end of the feed roller 3 is provided with a magnetic member 4. The frame 1 is fixedly provided with an electromagnet 5 at the end of the conveying roller 3. The electromagnet 5 is used for generating a magnetic force for driving the magnetic member 4 to move along the rotating shaft 2. When the electromagnet 5 is electrified, the magnetic field of the electromagnet 5 acts on the magnetic part 4, so that the magnetic part 4 moves left and right along the rotating shaft 2 under the action of the electromagnet 5. Specifically, the magnetic member 4 may be an object having magnetic permeability, such as an iron block. The magnetic member 4 may also be a permanent magnet and the direction of the current of the electromagnet 5 may be adjustable. This makes the magnetic poles of the electromagnet 5 adjustable. When the same poles of the electromagnet 5 and the permanent magnet are opposed, the magnetic member 4 moves away from the electromagnet 5. When the different poles of the electromagnet 5 and the permanent magnet are opposed, the magnetic member 4 moves away from the electromagnet 5. This makes it possible to adjust the moving direction of the conveying roller 3 by adjusting the magnetic pole direction of the electromagnet 5.

The utility model discloses a when unreeling the conveying roller of rectifying a deviation and using, the material such as cardboard after unreeling walks around conveying roller 3 and removes, and then makes conveying roller 3 ceaselessly follow the removal of material and rotate. When the materials deviate, the power supply of the electromagnet is switched on, and then the electromagnet 5 generates a magnetic field. The magnetic part 4 moves under the magnetic force of the electromagnet 5, so that the conveying roller 3 drives the material to move and return to a normal position. Thereby achieving the purpose of correcting the deviation.

The unreeling deviation-rectifying conveying roller controls the conveying roller 3 to move left and right through the magnetic force of the electromagnet 5. Simple structure and low cost.

In the present embodiment, both ends of the conveying roller 3 are provided with the magnetic members 4. The frame 1 is provided with electromagnets 5 at both ends of the conveying roller 3. The magnetic member 4 is an iron block. When the electromagnet 5 on one side is energized and the electromagnet 5 on the other side is de-energized, the conveyance roller 3 moves toward one end of the energized electromagnet 5. Alternatively, when the magnetic forces generated by the electromagnets 5 at both ends of the conveying roller 3 are different, the conveying roller 3 moves to one electromagnet 5 having a large magnetic force. The moving direction of the conveying roller 3 can be controlled by controlling the on-off and the magnetic force of the electromagnets 5 at the two ends of the conveying roller 3, and then the deviation can be corrected.

In this embodiment, the conveying roller 3 further includes a supporting sleeve 31 and two sliding blocks 32 sleeved on the rotating shaft 2. Two sliders 32 are connected to both ends of the support sleeve 31. The two sliders 32 can slide along the rotation shaft 2. The conveying roller 3 is rotatably sleeved outside the supporting sleeve 31. The supporting sleeve 31 is supported on the rotating shaft 2 through the sliding block 32, so that the conveying roller 3 and the supporting sleeve 31 move smoothly relative to the rotating shaft 2. Meanwhile, the conveying roller 3 rotates relative to the support sleeve 31, and the slider 32 slides relative to the rotating shaft 2, so that the rotation and the sliding of the conveying roller 3 do not interfere with each other. The device is more stable and reliable.

In this embodiment, the conveying roller 3 and the support sleeve 31 are connected by a bearing. The bearings make the rotation of the conveying roller 3 relative to the support sleeve 31 smoother.

In this embodiment, the two magnetic members 4 are respectively disposed on the two sliders 32. The electromagnets 5 are all provided with magnetic force adjusting switches. The magnetic force of the electromagnet 5 can be adjusted, and the movement direction and the movement speed of the conveying roller 3 can be adjusted conveniently.

In this embodiment, the surface of the conveying roller 3 is provided with an anti-slip silica gel. This prevents the sheet from slipping with respect to the feed roller 3 and impairing the correction capability of the feed roller 3.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
