Improved steel coil decoiler capable of improving leveling precision

Abstract

The invention provides an improved steel coil decoiler capable of improving leveling precision. A bottom roller is fixedly installed between every two adjacent flattening rollers and on the upper surface of a machine bin, fixing rods are installed on the portions, on the inner wall of the machine bin, of the lower surfaces of the flattening rollers in a sliding mode, pressing wheels are rotatablyinstalled at the tail ends of the fixing rods, magnets are arranged in the top ends of the fixing rods, and a corresponding coil is arranged above the magnets and inside the machine bin. In the leveling process of the surface of a steel coil base, the diameter is smaller and smaller, the left end of a supporting rod attached to the surface of a steel coil is gradually downward, therefore a slidingrod is driven to move in a sleeve to adjust the positions of a metal sheet and a variable resistor, current in the coil connected with the variable resistor in series is adjusted, it is guaranteed that a magnetic field generated by the coil pushes the magnets, the fixing rods are pushed to drive the pressing wheels to move downwards, the tensioning state of the steel coil in the leveling processis automatically adjusted according to the diameter change of the steel coil in the leveling process, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of steel plate processing, and in particular relates to an improved steel coil leveling machine which improves the leveling precision. Background technique [0002] The flattening machine is a machine that performs a series of processing operations such as uncoiling, leveling, and shearing of metal sheets. In the production and processing of thin steel plates, it is also necessary to flatten and shear through the flattening machine to become a relatively standardized coil or sheet. In the process of actual use, the steel plate needs to be in the form of a flat plate, so it needs to use a flattening machine to change from a roll type to a flat type. [0003] During the leveling process, the steel coil cannot be tensioned, resulting in a wavy surface of the steel plate after leveling. In addition, the tension state of the steel coil during leveling cannot be automatically adjusted according to the diameter cha...

[0003] During the leveling process, the steel coil cannot be tensioned, resulting in a wavy surface of the steel plate after leveling. In addition, the tension state of the steel coil during leveling cannot be automatically adjusted according to the diameter change of the steel coil leveling process. It affects the leveling accuracy of the steel coil and affects the leveling effect. Therefore, in view of this, the existing structure and defects are studied and improved, and an improved steel coil leveling machine with improved leveling accuracy is provided in order to achieve more practical value. the goal of
