Paint scratch prevention device for longitudinal shearing production line of purline workshop

Abstract

The invention relates to equipment for longitudinal shearing production and splitting of a color-coated steel plate, and particularly discloses a paint scratch prevention device for a longitudinal shearing production line of a purline workshop. The device comprises the longitudinal shearing production line, and is characterized in that a laminating machine is arranged on the front part of the longitudinal shearing production line, and comprises a bracket, and protective film air expanding shafts, protective films, a tension detection device, a spiral guide roller, film pressing leather rollers, color steel deviation rectification regulation device, plate surface smoothing rollers, an optical sensor, a PLC (Programmable Logic Controller) and the like, which are arranged on the bracket. The device has the beneficial effects that the device is simple in structure and convenient to use, and can be well jointed with a conventional longitudinal shearing production line for operation; when the device is used, an electric system is adopted for control after the loading (protective film) of an operator, so that time, power and labor are saved, the quality of a product is improved, and the phenomenon of paint scratches is eliminated.

Description

technical field [0001] The invention relates to equipment for slitting and slitting production of color-coated steel plates, in particular to an anti-scratch paint device for a slitting production line in a purlin workshop. Background technique [0002] In the slitting production line of the purlin workshop in the current steel product manufacturing center, there is paint scratching when the color-coated coil is slitting and slitting. The main root cause is that the equipment process is oriented, the production line is purchased in an earlier year and has a long service life, and the production process is relatively backward. It cannot meet the high-quality appearance requirements of the product; the current slitting production process is that the steel coil is expected to be tightly wound at the end of the winding. Due to the certain production process of the equipment, the steel plate needs to be straightened at the damping and winding position. Now the structure of th...

The main root cause is that the equipment process is oriented, the production line is purchased in an earlier year and has a long service life, and the production process is relatively backward

It cannot meet the high-quality appearance requirements of the product; the current slitting production process is that the steel coil is expected to be tightly wound at the end of the winding. Due to the certain production process of the equipment, the steel plate needs to be straightened at the damping and winding position. Now the structure of the damping part is hydraulic The top plate of the cylinder directly presses the color-coated steel plate, and the pressure of the top plate of the hydraulic cylinder on the color-coated steel plate is very large, so that the painted steel plate after slitting passes through the felt of the top plate of the hydraulic cylinder, and paint is scratched on it
