Photoelectric deviation rectification instrument with adjustable application range

Abstract

The invention relates to the technical field of photoelectric deviation rectification detection and discloses a photoelectric deviation rectification instrument with an adjustable application range. The photoelectric deviation rectification instrument comprises a shell, wherein moving blocks are movably connected with a left face and a right face of the shell, clamping plates are movably connectedwith the middles of the two moving blocks, racks located on the right side of the shell are fixedly installed on the right side faces of the clamping plates, a first rack is fixedly installed on a right side face of the shell, and a first motor is fixedly installed on the right side face of the first rack. The photoelectric deviation rectification instrument has the advantages that a second threaded rod is meshed with a meshing plate, the meshing plate can move up and down, the meshing plate drives the lifting plate to move up and down, an upper pressing roller installed on a right face of the lifting plate can move up and down along with the lifting plate, so a distance value between the lower pressing roller and the upper pressing roller is changed, the second threaded rod is made to rotate to drive the upper pressing roller to move, the upper pressing roller tightly presses the detection piece, the device can detect coiled materials of different thicknesses, and practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of photoelectric deviation correction detection, in particular to a photoelectric deviation correction instrument with an adjustable use range. Background technique [0002] With the rapid development of basic processing fields such as chemical industry, papermaking, textile and clothing, packaging and printing, ferrous and non-ferrous metals, the development of automation control systems tends to be high-precision, high-resolution, high-adaptability, strip In the winding production process, various external disturbances often affect it, causing it to deviate during the walking process. The photoelectric correction device detects the line on the detection part through the detection device to judge the position of the detection part. Check whether the deviation occurs, and correct the deviation phenomenon of the strip during winding. [0003] The existing photoelectric correction device adjusts the offset of...

Problems solved by technology

[0003] The existing photoelectric correction device adjusts the offset of the detection part through the adjustment device, and uses the upper and lower pressure rollers to press and fix the detection part, and moves the position of the pressure roller to adjust the position of the detection part, but the existing photoelectric correction device The position between the upper and lower pressure rollers is relatively fixed, so that the device can detect coils with a single thickness, but cannot meet the detection of coils with different thicknesses, reducing the practicability of the device

[0004] The photoelectric detection device sets the coiled material on the conveying roller. When in use, the conveying roller drives the coiled material to rotate for coil feeding. The length of the coiled material on the conveying roller of the existing photoelectric detecting device is single and fixed. When the length of the coiled material is relatively Hours, the coil will slide relative to the conveying roller during the rotation process, which increases the correction amount of the device, increases the workload, and reduces the practicability of the device

[0005] When the photoelectric detection device detects the lines on the detection piece, when the detection piece deviates, the position of the detection piece can be adjusted by moving the upper and lower pressure rollers, but when the detection piece is stretched and deformed, the detection device detects the line The position of the test piece remains unchanged, the device cannot judge that the state of the test piece is abnormal, the correction device does not adjust the test piece, and the test piece is in a stretched state, which may lose its original function and reduce the use effect of the device
