Problems solved by technology
[0002] When the strip passes through the edge trimmer, it is easy to cause a material jam accident due to the deviation of the strip from left to right. Once the material is jammed, it will cause impact damage to the equipment. In order to ensure the safety of the equipment, it is necessary to control the deviation of the belt.

Embodiment Construction
[0020] The present invention will be described in further detail below through examples, and examples are only used to illustrate the present invention, and do not limit the scope of the present invention.
[0021] see Figure 1-2 A novel 1+4 aluminum hot rolling edge trimming machine strip threading deviation mathematical model control method is characterized in that it includes the following steps:
[0022] 1) Obtain the center parameter of the crown meter, which is measured by the crown meter, and is used to reflect the deviation between the center line of the strip and the center line of the equipment, wherein the center line data when the head of the strip reaches the trimming machine is recorded as S1 , the centerline data when the coiling tension reaches the target value is recorded as S2;
[0023] 2) Obtain the time when the head of the strip arrives at the trimming machine and denote the time when the head of the strip arrives at the trimming machine as T1;

The invention belongs to the field of automatic control of aluminum processing technology, and in particular relates to a new 1+4 aluminum hot continuous rolling edge trimming machine belt threading deviation mathematical model control method. The new edge trimming machine belt threading deviation mathematical model is mainly controlled by a crown The parameters of the central line of the strip, the time when the strip reaches the trimming machine, the time when the tension of the coiler is established, and the time when the coiling tension reaches the target value are composed. The principle is to control the roll gap through the calculation results of the mathematical model to achieve The purpose of improving the yield and prolonging the life of the equipment. Its control process is all automatically completed by computer, which has the characteristics of intelligence and high stability.
