[0026] The movable pressing frame 2 includes a pressing fixed frame 8, left and right movable sliding wheel support plates 9, a pressing fixed frame screw 11, a pressing fixed frame screw rotating rod 12, a pressing fixed frame screw base 10 and left and right movable pulleys 18; the pressing fixed frame 8 is placed on the workbench 3, and left and right movable sliding wheel support plates 9 are provided on both inner sides of the pressing fixed frame 8. Both ends of the left and right movable sliding wheel support plates 9 are installed with left and right movable pulleys 18; the left and right movable pulleys 18 are movably provided on the workbench 3;

[0027] The downward pressure fixing frame screw rod 11 is screwed onto the downward pressure fixing frame 8, and the top end of the downward pressure fixing frame 8 is connected to the downward pressure fixing frame screw rod rotating rod 12; the bottom end of the downward pressure fixing frame 8 is installed with a downward pressure fixing frame screw rod base 10, and the downward pressure fixing frame 8 and the downward pressure fixing frame screw rod base 10 can rotate relative to each other; two left and right movable pulleys 18 are symmetrically installed on the downward pressure fixing frame screw rod base 10, and are respectively movably arranged in the grooves on the two inner sides of the downward pressure fixing frame 8, and the downward pressure correction top plate 5 is installed at the bottom of the downward pressure fixing frame screw rod base 10.

[0028] Working principle:

[0029] First, place the device at the designated location, and then raise or lower the two movable lifting brackets 1 on the left and right sides according to the ground conditions to keep the workbench 3 level;

[0030] Then, according to the roller diameter to be checked, select the same downward correction base 4 and downward correction top plate 5, place both ends of the roller on the downward correction base 4, and keep the curvature of the roller upward;

[0031] There are two movable lower pressure frames 2, one for fixing and pressing one end of the roller, and the other movable lower pressure frame 2 is used to align with the part that needs to be calibrated. Rotate the screw rod 12 of the lower pressure fixing frame (a force rod can be used) to apply corresponding force according to the bending degree of the roller and hold it for 2 minutes. Remove it to check the bending condition and repeat this step repeatedly according to the calibration condition.

[0032] The roller downward pressure correction base 4 has fixed positioning holes on the platform for easy installation; the downward pressure correction top plate 5 is disassembled and assembled (different diameter rollers use different downward pressure correction bases 4 and downward pressure correction top plates 5; 26mm / 27mm / 28mm / 28.5mm / 30mm / 32mm).

[0033] During operation, when adjusting the movable lifting bracket 1, the adjustment is performed by rotating the pull arm 13. When the pull arm 13 rotates, the connecting pin 6 slides in the pull slot; the two pull arms 13 respectively drive the connected workbench lifting screw 15 to rotate, and the workbench lifting screw 15 and the workbench lifting base 16 are screwed together, and the position of the workbench lifting base 16 is restricted by the workbench 3, and then the workbench lifting base 16 slides up and down along the movable lifting bracket leg slot 22 to achieve the height adjustment of the workbench 3;

[0034] When pressing down, the screw rod rotating rod 12 of the pressing down fixed frame is rotated, and the screw rod rotating rod 12 of the pressing down fixed frame drives the screw rod 11 of the pressing down fixed frame to rotate. The screw rod 11 of the pressing down fixed frame is screwed to the pressing down fixed frame 8, and the screw rod 11 of the pressing down fixed frame rotates and moves downward. The pressing down fixed frame 8 and the screw rod base 10 of the pressing down fixed frame can rotate relative to each other, and then the pressing down fixed frame 8 drives the screw rod base 10 of the pressing down fixed frame to move downward, and the lifting sliding wheel 17 on the screw rod base 10 of the pressing down fixed frame moves downward along the groove on the side of the pressing down fixed frame 8 to position the screw rod base 10 of the pressing down fixed frame; thereby realizing the downward pressure of the downward pressure correction top plate 5 on the screw rod base 10 of the pressing down fixed frame

[0035] The position of the movable lower pressing frame 2 on the workbench 3 can be adjusted left and right by the left and right movable pulleys 18.

[0036] The two movable lifting brackets 1 of the device can be raised and lowered according to the ground conditions to always ensure that the platform is level during operation.

[0037] The movable lifting bracket 1 is equipped with movable bottom wheels 7 for easy movement forward, backward, left and right.

[0038] This device uses two pressing devices to firmly fix the rollers and ensure that the roller accuracy requirements are met.

[0039] The device can be equipped with a downward pressure correction base 4 and a downward pressure correction top plate 5 of different sizes, which can be used in conjunction with each other according to the diameter of the roller.

[0040] The device is easy to install and use, simple to operate, and one person can complete the roller calibration work. The calibration accuracy can reach 2 wires, which can meet the calibration requirements of rollers of various diameters in textile factories.

[0041] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
