Coiled material conveying and tensioning device

Abstract

The invention discloses a coiled material conveying and tensioning device, which comprises a workbench support (1), and a first guide roller assembly (2), a second guide roller assembly (3), a tensioning guide roller assembly (4) and a tensioning guide roller support assembly (5) which are arranged on the workbench support, wherein the tensioning guide roller support assembly is arranged between the first guide roller assembly and the second guide roller assembly; the tensioning guide roller assembly is erected on the tensioning guide roller support assembly; the tensioning guide roller assembly is positioned below the first guide roller assembly and the second guide roller assembly; the first guide roller assembly comprises a first guide roller; the second guide roller assembly comprises a second guide roller; the tensioning guide roller assembly comprises a tensioning guide roller; and a coiled material passes through the first guide roller, the tensioning guide roller and the second guide roller in turn to reach a tension state. The coiled material conveying and tensioning device has a simple structure and has the advantages of high response speed and capacity of automatically adjusting the tension of the coiled material at a feed end.

Description

technical field [0001] The invention relates to a coil conveying tensioning device. Background technique [0002] At present, large-scale coil processing machines such as general coating machines, film laminating machines, and compound machines are generally equipped with tensioning devices during the coil conveying stage. Slippage on the drive pulley inside the machine or excessive deflection between idler rollers. The tensioning device preferably has the performance of automatically adjusting the tension and responding quickly. [0003] The known tensioning devices generally adjust the tension through the mechanical structure, such as adjusting the position of the tensioning roller through the screw pair, or through the swing arm. The structure is complex, the volume is huge, and the guide rollers are intricate, which easily leads to the guiding movement of the coil. It is not smooth, cannot be adjusted quickly and automatically in real time, and when it is used for a lo...

Problems solved by technology

[0003] The known tensioning devices generally adjust the tension through the mechanical structure, such as adjusting the position of the tensioning roller through the screw pair, or through the swing arm. The structure is complex, the volume is huge, and the guide rollers are intricate, which easily leads to the guiding movement of the coil. It is not smooth, cannot be adjusted quickly and automatically in real time, and when used for a long time, the tensioning device will be worn and the tensioning effect will be reduced. The process of repairing and adjusting the tension is time-consuming and laborious, which will affect the progress of the entire production process.
