Multi-coil binding machine for hot-rolled narrow strip steel

Abstract

The invention provides a multi-coil binding machine for hot-rolled narrow strip steel. The multi-coil binding machine comprises a platform and a transverse track arranged on the platform, wherein an uncoiler is arranged on the right side of the platform; a coil conveying trolley on which steel coil carrier rollers are arranged is arranged on a longitudinal track configured with the platform; a coil penetrating trolley positioned on the left side and a trolley positioned on the right side are arranged on the transverse track; the coil penetrating trolley is provided with a coil penetrating trolley driving mechanism; the trolley is provided with a trolley positioning hydraulic cylinder; a binding belt bending mechanism, a binding belt head clamping and pulling mechanism and a follow-up chassis are arranged on the trolley; and a two-roller clamping and conveying mechanism, a clamping roller straightening mechanism, a binding belt shearing and bending mechanism, an electromechanical limiting switch and a welding machine are arranged on the follow-up chassis. The multi-coil binding machine can replace manual binding, and the automation degree of binding, the safety and reliability of work, the binding quality and the binding speed are greatly improved.

Description

technical field [0001] The invention relates to packaging machinery, in particular to a hot-rolled narrow-strip multi-volume binding machine. Background technique [0002] In the hot-rolled narrow strip steel production line, the multi-coil bundling of finished steel coils is a very critical and important process. At present, most steel mills use manual bundling. Workers work in a high temperature, dusty, and noisy environment, which is not only harmful to their health, but also has poor binding quality. Loose coils often occur during hoisting and transfer, and even loose coils, resulting in rework and a lot of duplication of labor. Bring unnecessary economic losses to steel mills. A previous patent application with the application number 201210052200.2 discloses a hot-rolled narrow-strip multi-coil automatic bundling machine, which is used to replace manual bundling. The hot-rolled narrow-strip multi-coil automatic bundling machine includes a The horizontal track and the...

AI Technical Summary

Problems solved by technology

The hot-rolled narrow-strip multi-coil automatic bundling machine has the following problems: ① The coil-through beam with a rectangular cross-section cannot adapt to the "tongue" in the inner circle of the steel coil (that is, the head of the steel strip is tilted), and it is prone to wear during the bundling process. The insertion of the coil beam is blocked and the "tongue" is pressed, causing the steel coil to be uncoiled during rotation, resulting in waste products, causing unnecessary economic losses to the steel mill

②The lifting of the upper part of the coiling car is directly lifted by two oil cylinders arranged diagonally. Not only is the stability poor, but one of the oil cylinders is very close to the steel coil and is baked by the steel coil at a high temperature of more than 600 degrees. Once the oil cylinder and the oil pipe leak oil Very prone to fire accidents, there are serious safety hazards

③Insufficient ability to adapt to the change of steel coil diameter, it is difficult to meet the current requirements of various types of rolled steel coils and wide range of steel coil diameter changes

④The bundling speed is slow and the work efficiency is low, which cannot meet the requirements of the bundling process for the high-speed production of the current hot-rolled narrow strip steel production line

⑤Lack of effective and practical leading intelligent control mechanism, manual intervention is required to complete the bundling work, and no real automation has been realized
