[0025] In detail: the two sides of rotating support 2 are respectively fixed with mounting sleeve 10, and two mounting sleeves 10 are coaxial, two mounting sleeves 10 are respectively sleeved on rotating shaft 3, rotating shaft 3 not only can rotate on two mounting sleeves 10, but also can move horizontally along the axial direction;

[0026] The two ends of rotating support 2 are also respectively fixed with driving disc 5, and each driving disc 5 is located between two mounting sleeves 10;It needs to be explained that: one side of driving disc 5 is provided with an inclined angle.

[0027] Support 1 is mounted with screw rod 6 along the length direction, screw rod 6 is preferably bidirectional screw rod, one end of screw rod 6 is provided with driving source (not shown in the figure) penetrating support 1, and the driving source is motor, which plays a role of driving screw rod 6 by the setting of driving source;And the two ends of screw rod 6 are respectively threadedly installed with sliding seat 7, screw rod 6 can drive two sliding seats 7 to move in opposite or opposite directions;The top of each sliding seat 7 is fixed with push block 8 extending to the outside of support 1, and the opposite side of two push blocks 8 is provided with driving surface 9, in detail: driving surface 9 is inclined surface or slope;By the setting of driving surface 9, the inclined angle of driving disc 5 can be extruded;Driving disc 5 drives drag roller 4 to move along the axial direction through rotating shaft 3, thereby playing the role of deviation correction to filter cloth;

[0028] It should be noted that the two inner side walls and the inner bottom wall of the support 1 are respectively fixed with guide rods 11 along the length direction, and the two sides and the bottom of the sliding seat 7 are provided with guide grooves 12, and the guide grooves 12 slide on the guide rods 11. Through the cooperation of the guide rods 11 and the guide grooves 12, the sliding seat 7 is limited, preventing the sliding seat 7 from rotating during movement.

[0029] The ends of the two supports 1 are provided with the same "U"-shaped support 14, and the upper part of the "U"-shaped support 14 is provided with two adjusting holes 18, respectively. An installation shaft 19 is slidably installed in each adjusting hole 18, so that the installation shaft 19 can be adjusted on the adjusting hole 18. A locking nut 20 is threadedly installed on the upper part of the installation shaft 19. Through the setting of the locking nut 20, the installation shaft 19 is fastened, preventing the installation shaft 19 from loosening during use. A gasket 21 is provided between the locking nut 20 and the "U"-shaped support 14 and is sleeved on the installation shaft 19. Through the setting of the gasket 21, the fastening effect is further improved. The bottom end of the installation shaft 19 is fixed with an "L"-shaped mounting seat 15 which passes through the adjusting hole 18, and an infrared sensor 16 is installed below the mounting seat 15.

When adjusting the infrared sensor 16, first loosen the locking nut 20 so that the installation shaft 19 can move in the adjusting hole 18 along the length direction. The installation shaft 19 drives the infrared sensor 16 to move through the mounting seat 15, so that the distance between the two infrared sensors 16 can be adjusted according to the width of the filter cloth a.

[0032] If the filter cloth deviates, the infrared sensor 16 cannot detect the filter cloth a. The information detected by the infrared sensor 16 is transmitted to the controller, and the controller controls the corresponding driving source. The driving source can drive the lead screw 6 to rotate. During the rotation of the lead screw 6, the two sliding seats 7 can move in opposite directions. When the two sliding seats 7 drive the push blocks 8 to move in opposite directions, the driving surface 9 of the push block 8 can extrude the inclination angle of the driving disc 5. Under the extrusion of the driving disc 5, the rotating shaft 3 can move along the axis direction. The rotating shaft 3 can drive the filter cloth a to correct the deviation through the drag roller 4. Thus, the deviation correction work is completed. If the infrared sensor 16 detects the filter cloth, the driving source drives the lead screw 6 to rotate in the opposite direction, so as to drive the two sliding seats 7 to move in the opposite direction, so that the push block 8 above the sliding seat 7 is separated from the driving disc 5.
