All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, a deviation rectifying mechanism for printing a strip-shaped plate comprises a fixed support 1, a fixed connecting shaft 2 is fixedly sleeved at the bottom end inside the fixed support 1, a deviation rectifying roller 3 is movably sleeved at the middle part of the outer surface of the fixed connecting shaft 2, a reset spring 4 is movably sleeved at one side of the outer surface of the fixed connecting shaft 2 and between the end surface of the deviation rectifying roller 3 and one side of the fixed support 1, a transmission sleeve 5 is fixedly sleeved at the top end inside the fixed support 1, an electromagnetic coil 6 is arranged at one side of the inner wall of the transmission sleeve 5, a limit slider 7 is movably sleeved at the other side of the inner cavity of the transmission sleeve 5, a permanent magnet ring 8 is fixedly arranged at one end of the electromagnetic coil 6 of the limit slider 7, a support connecting shaft 9 is movably sleeved inside the limit slider 7, one end of the support connecting shaft 9 extends to one side outside the transmission sleeve 5 and is fixedly connected with one end of the fixed connecting shaft 2 through an adjusting sleeve 10, two sides of the inner cavity of the adjusting sleeve 10 are respectively in threaded transmission connection with one end of the supporting connecting shaft 9 and one end of the fixed connecting shaft 2.

Wherein, form the electric feedback connection between the inside of transmission sleeve 5 and control system, the photoelectricity displacement detecting system to real-time signal according to photoelectricity displacement detecting system feedback effectively controls the magnetic field size that produces in transmission sleeve 5, and then the displacement size of the running roller 3 of rectifying along the fixed even 2 orbit of axle of accurate regulation and control above that.

In this technical scheme, the number of the running roller 3 of rectifying is established to two sets and its outside establishes to the toper structure, and simultaneously, two sets of running rollers 3 of rectifying are located same vertical plane and are central array and arrange.

When the deviation correcting roller 3 is rotated, the linear speeds at various positions on the surface of the deviation correcting roller are different according to the relationship between the linear speed and the angular speed, so that the deviated strip-shaped material is slowly corrected to be in a normal conveying state, and the phenomenon of excessive pulling of the deviated strip-shaped material during correction is avoided.

The two groups of deviation correcting rollers 3 are arranged at different positions, so that when the belt-shaped material deviates in different directions in the conveying process, the deviation correcting rollers 3 at different positions can be effectively triggered to correct the belt-shaped material in different directions.

In this technical scheme, fixed connecting shaft 2 is the slope and arranges and with support connecting shaft 9 and keep the state that parallels, simultaneously, keeps the state of level and parallel between the generating line of two sets of running roller 3 adjacent surfaces of rectifying.

Wherein, to the setting of fixed even axle 2, the running roller 3 of rectifying for rectifying 3 when moving along the orbit of fixed even axle 2, make its surface can take place to contact between with the surface of banded material, and drive it and take place the rotation action under friction drive's effect, simultaneously, make the surface of rectifying running roller 3 when the surface contact with banded material, it is more even to the pressure that the banded material was applyed, can not cause the phenomenon of indentation on the surface of banded material.

as shown in fig. 4, wherein the dotted arrow indicates the direction of correction of the strip-like material, and the solid arrow indicates the rotation direction of the skew correcting roller 3:

when the belt-shaped material deviates to the left side in the conveying process, the transmission sleeve 5 in the upper deviation correcting roller 3 is triggered by the feedback of the photoelectric displacement detection system, so that the upper deviation correcting roller 3 is driven to move to the right side along the track of the fixed connecting shaft 2 and is in frictional contact with the upper surface of the belt-shaped material, the belt-shaped material rotates along with the transmission sleeve, and then the belt-shaped material in contact with the belt-shaped material is driven to deviate to the right side under the difference of linear speeds at the positions of the sectional groove 11 on the deviation correcting roller 3 and the conical surface of the belt-shaped material, so that the belt-shaped material is corrected;

when the belt-shaped material deviates to the right side in the conveying process, the transmission sleeve 5 in the lower deviation correcting roller 3 is triggered by the feedback of the photoelectric displacement detection system, so that the lower deviation correcting roller 3 is driven to move to the left side along the track of the fixed connecting shaft 2 and is in frictional contact with the lower surface of the belt-shaped material, the belt-shaped material rotates along with the transmission sleeve, and then the belt-shaped material in contact with the belt-shaped material is driven to deviate to the left side under the difference of linear speeds at the positions of the sectional groove 11 and the conical surface of the belt-shaped material on the deviation correcting roller 3 so as to correct the belt-shaped material.
