Background
In order to increase the tension at the exit of the temper mill and correspondingly reduce the coiling tension, S rolls (also called tension rolls) are provided at the exit of the cold rolling temper mill. Generally, the thickness of 0.8mm is used as a boundary, a strip with the thickness of more than 0.8mm does not pass through an S roller, and directly enters a coiling machine from an outlet of a leveling machine through an upper roller of the S roller, and a strip with the thickness of less than 0.8mm enters the coiling machine through the S roller, so that 2 angles appear when a strip head enters the coiling machine, and the belt wrapper needs to meet the wrapping angle for 2 times to meet the winding requirement.
At present, the main structure of the belt wrapper is as follows: the device consists of a winding-assisting belt, a group of winding-assisting rollers, an upper swing guide plate hydraulic cylinder, a lower arm swing hydraulic cylinder and a frame. When the strip enters the coiling machine through the S roller, the upper guide plate of the wrapper needs to swing downwards to form a olecranon with the lower arm, and the strip is guided to enter the coiling machine for wrapper. When the strip enters the coiler without passing through the S roller, the upper swing guide opens, the lower arm requires a larger wrap angle to guide the strip head into the coiler, and the lower arm swing cylinder requires a secondary extension.
The problem that current belt helps a roll ware exists: 1) When the strip enters the coiling machine through the S roller, the upper guide plate of the wrapper needs to be swung down, and the structure is complex and the reliability is low. 2) When the strip does not pass through the S roller and enters the coiling machine, the lower arm needs a larger wrap angle to guide the strip head to enter the coiling machine, and the lower arm swinging hydraulic cylinder needs secondary extension, so that the structure is difficult to control and difficult to realize.
