Automatic bundling device for preventing steel coil from being loosened

Abstract

The invention discloses an automatic bundling device for preventing a steel coil from being loosened. The device is arranged on a coil unloading trolley base of a strip steel production line and comprises a bundling belt bypassing guide rail mechanism, a bundling belt placing mechanism, a bundling belt conveying mechanism, a bundling belt tightening mechanism, a bundling belt pressing mechanism and a heat sealing breaking mechanism, wherein the bundling belt bypassing guide rail mechanism comprises a gantry movable guide rail which is arranged in a cavity of the coil unloading trolley base and can do arc motion, a lead-out fixed guide rail arranged above one side of the gantry movable guide rail, and a lead-in fixed guide rail arranged above the other side of the gantry movable guide rail; and the gantry movable guide rail, the lead-out fixed guide rail and the lead-in fixed guide rail form a bundling belt bypassing annular rail. The device has a simple structure, is convenient to operate, low in cost and easy to maintain, has a coil unloading function and an automatic steel coil bundling function, avoids the original repeated manual operation mode, radically eliminates potential safety hazards, and solves the problem that the steel coil is loosened in the hoisting process.

Description

technical field [0001] The invention relates to a steel coil binding device, in particular to a steel coil anti-loose automatic binding device. Background technique [0002] In the metallurgical industry, steel coil is a major product form. Before the strip steel becomes the final product, it often has to go through multiple processes. Every time the strip goes through a process, it must be uncoiled, from the process to the coiling, and then the coiled steel coil is sent to the entrance of the next process to wait for uncoiling. Because the steel strip itself has certain strength and elasticity, the tail of the strip steel after coiling is not easy to tighten up, and it is easy to directly cause the steel coil to be loosened, and in serious cases, it is easy to cause personal injury and disability. Therefore, it is necessary to implement circumferential bundling on the steel coils to avoid loose coils during the process of hoisting and transporting them to the next product...

Problems solved by technology

Therefore, the document "Zhu Chenggong, Yan Mantang, Zhang Fengxian, Yu Buming, Application of PLC automatic control on hot-rolled coiling and bundling machine, "Meishan Science and Technology", No. 3, 2011" introduced the The application of the strapping machine. The system is based on Siemens 300 series PLC. Although it can complete the automatic bundling function, the bundling equipment and the unloading trolley are not integrated. The unloading trolley has to transport the steel coils to the bundling operation area. Occupies a large production space. On the other hand, because the strapping groove is fixed, after the strapping is completed, the unloading trolley needs to move horizontally to transport the steel coil to the lifting saddle and wait for the crane to lift the steel coil away.
