As a preference, in stepb, when sliding roll surface one and sliding roll surface two resets, in rectifying cylinder promotion
Mandrel is moved to the left, and makes drive block one that bearing block five be driven to be moved to the left, while making drive block two that bearing block three-dimensional be driven to move to left
It is dynamic, bearing block five and bearing block three respectively drives sliding roll surface two, sliding roll surface one is moved to the left, by spring two, spring four with
Rectifying cylinder drives sliding roll surface one, sliding roll surface two to reset jointly；
As a preference, in step c, when sliding roll surface one and sliding roll surface two resets, in rectifying cylinder promotion
Mandrel moves right, and makes drive block one that bearing block four be driven to move right, while making drive block two that bearing block two be driven to move right
Dynamic, bearing block four and bearing block two respectively drive that sliding roll surface one, sliding roll surface two moves right and Rapid reset, by spring
One, spring two and rectifying cylinder drive sliding roll surface one, sliding roll surface two to reset jointly.
Compared with the existing technology, what the present invention had has the technical effect that
(1) transmission belt of the invention correction roller component, in roller rotation process, when sliding roll surface connects with transmission belt
When touching, the sliding relatively quiet roll surface of roll surface is axially moveable, and transmission belt can be driven to be moved in the width direction, thus to transmission belt
It rectifies a deviation.
(2) roller uses multi-segment structure, increases sliding roll surface in the angle in turning circumference direction, reduces quiet roll surface and exist
The angle in turning circumference direction so that roller during rotation, extend sliding time for contact with transmission belt of roll surface, increase shifting
The opportunity that dynamic sliding roll surface is rectified a deviation；In addition, during correction, sliding roll surface one with slide roll surface two both can be to same
Direction axial movement, and rectify a deviation to same direction, and can move axially round about respectively, and respectively to opposite
Direction is rectified a deviation, and is conducive to carriage to sliding roll surface using flexible control mode.
(3) it slides roll surface one and sliding roll surface two passes through sliding block one, sliding block two, sliding slot one, sliding slot two and support sleeve respectively
Axial sliding fit rotates together when can move axially with support sleeve.
(4) roller component is rotated using motor, transmission shaft driving support sleeve, roller, while being divided using drive block two
Not Qu Dong bearing block two, bearing block three move backward, bearing block two, bearing block three respectively drive sliding roll surface two, sliding roll surface
One correction moved backward to realize left and right, utilizes the bearing block one of axial restraint, bearing block six, spring three and spring four
Come the reset realized sliding roll surface one, slide roll surface two.
(5) drive block one can be reversed by bearing block four, the driving sliding of bearing block five roll surface one, sliding roll surface two
Mobile, drive block one drives sliding roll surface one and sliding roll surface two towards movement in the same direction simultaneously with the cooperation of drive block two, can make to pass
Dynamic band is rectified a deviation when contacting with sliding roll surface one or sliding roll surface two, increases the opportunity of correction, while working as transmission belt simultaneously
Correction is carried out when contacting with sliding roll surface one and sliding roll surface two can increase transmission belt and slide the contact area of roll surface, improve
Frictional force between the two prevents from skidding between transmission belt and sliding roll surface during correction, improves the success of primary correction movement
Rate.
(6) spring one, spring two, spring three and spring four are sheathed on the outside of central axis respectively, and central axis is to each spring
It is limited.
(7) position sensor is for detecting sliding roll surface one, quiet roll surface and sliding roll surface two in circumferential locations, position
Sensor to the controller of error correct cylinder transmission signal for determine when sliding roll surface one, sliding roll surface two turn to
The position of transmission belt contact, distance measuring sensor are used to measure the spacing of transmission belt and roller both sides of the edge and pass to the controller
The number of delivering letters is for judging whether transmission belt deviates the central location of roller.
(8) rate-determining steps of left-hand correction and dextrad correction are respectively adopted to distinguish in the working method of the roller component
The offset of both direction is corrected, control mode is simplified, improves the accuracy of single correction, and when sliding roll surface
One, sliding roll surface two can rectify a deviation again after resetting, acted by multiple correction, overcome and determined by roller revolving speed
The problem of single correction movement cannot be corrected in place completely caused by the limitation of correction opportunity.
(9) spring is cooperated to reply immediately sliding roll surface one, sliding roll surface two fastly using sliding roll surface one, sliding roll surface two
Position, not only improved work efficiency, but also can make to slide roll surface one, sliding roll surface two more quickly again under the high speed conditions of roller
Position, to precisely control the correction process to transmission belt.
