Anti-loosening mechanism with tape-tracking function

Abstract

The invention provides an anti-loosening mechanism with a tape-tracking function. The anti-loosening mechanism is positioned right below a coil of a coiling machine. The anti-loosening mechanism comprises a material receiving stage and an elevation cylinder. The material receiving stage is in a form of carrier rollers. A shank and a stop bar are respectively connected with the material receiving stage through a nut and washer. The shank and the stop bar respectively perform sliding with a machine body through the cooperation of slide bearings. The cylinder body of the elevation cylinder is engaged with the machine body. An oil cylinder rod of the elevation cylinder is connected with the material receiving stage. A gear and a shaft are fixed on the machine body through a support. The support is engaged on the machine body. The gear and the shaft are fixed through keys. The shaft and an encoder are connected through a coupler. The encoder is engaged on the support. The shaft and a mounting hole of the support match through a slide bearing. An ultrasonic sensor is arranged between two carrier rollers on the material receiving stage. The ultrasonic sensor is fixed on the material receiving stage through an ultrasonic sensor mounting support. The structure provided by the invention is safe and reliable, and has a characteristic of fast action.

Description

technical field [0001] The invention relates to a metallurgical plate and strip rolling equipment, in particular to an anti-unwinding mechanism with a coil tracking function. Background technique [0002] Coil unloading devices are widely used on strip mills to quickly unload finished coils or tailing scrap coils from coiler drums. The unloading device is driven by the lifting cylinder to move the receiving table upwards to move the supporting roller to press the coil. After the diameter of the coiler drum is reduced, the coiler is unloaded from the drum and placed in the storage coil under the cooperation of the push plate of the coiler. Seam on the road, so that the roll can be lifted away. The receiving table is generally in the form of idler or saddle, and there is a groove in the middle to facilitate the bundling of coils. In practice, when the strip is broken during the rolling process, the strip coil will be unwrapped rapidly, causing difficulty in threading the st...

AI Technical Summary

Problems solved by technology

In practice, when the strip is broken during the rolling process, the strip coil will be unwrapped rapidly, causing difficulty in threading the strip again or the unevenness of the outer edges of the strip coil will affect the yield. However, this method will cause indentations on the strip, which will affect the surface quality of the strip; or when the broken strip occurs, the unloading trolley will be lifted quickly and the receiving table will be pressed against the strip with a roller, because the trolley lift is It is realized by the button, and the response speed is slow, so this method is also difficult to prevent the phenomenon of unwinding after the tape is broken.

In this way, the auxiliary time of rolling is increased virtually, and the yield of the strip is reduced.
