Description
Technical Field
The utility model relates to a steel sheet production facility technical field specifically is an guiding mechanism of coiling machine tape trailer off tracking.
Background
In order to ensure the continuity of the production line, the production line is generally divided into two passages which enter a coiling machine to coil strip steel in turn. However, due to the shape of the head and tail of the belt, abnormal deviation often occurs, which affects the operations of centering, coil hanging, packaging and the like in the subsequent process. And the distance between the 2# coiling machine and the outlet shearing machine is far, so that the strip tail of the strip steel is not pulled by tension after the shearing is finished, and the deviation is easily caused. The deviation of the head or the tail of the coiling machine is mainly caused by the following conditions: (1) the head and tail plate shapes of the steel plate are poor; (2) steel plate single-side wave shape; (3) the pressure of the pinch roll is unbalanced; and (4) the tail EPC controls the abnormity.
In the prior art, automatic deviation correction is mainly performed through an EPC system, but the technology can be effective under the condition that a steel plate has large tension. When the strip tail is curled (namely after being sheared), tension is basically absent, smaller tension is mainly provided by a pinch roll, and if the pinch roll is poor in pressure balance, the roughness of a common press roll is lower, the friction force is small, the deviation rectifying effect is poor, the strip tail is easy to deviate, and the deviation of the strip tail of the coiling machine cannot be fundamentally avoided. In the production practice, particularly in the process of producing high-strength steel (such as more than 590), the tail coiling is more likely to cause deviation. The pressure of a pinch roll of a front pinch roll of the coiler often needs to be adjusted on site manually, so that the coiling deviation problem of the strip tail can be solved. However, the pressure of the compression roller is manually adjusted on site, so that the labor intensity is high, the manual adjustment is easy to make mistakes, and the like.
