Composition and working principle of the whole set of power pay off frame
The power pay off machine sets out 2 lines (or multiple lines). After the pay off passes through the balance bar machine, the position of the balance bar can be judged to realize that the pay off machine rotates forward or reversely or stops at zero point. After passing through the balance bar, the line finally enters the stranding machine, and the 2 lines (or multiple lines) are twisted together to finally realize the generation of products. For example, our commonly used network cable can be set out by power Wire rack to achieve production.
Functions of power pay off frame equipment
The whole set of equipment of power pay off rack should be realized: the feedback rod can quickly and accurately find the zero point when starting; the stable pay off of power pay off rack when running; and the tension of line can be accurately guaranteed when stopping.
The following are the requirements of a mechanical plant power pay off frame:
(1) When the swing rod is in the middle, the motor stops (commonly known as: zero position);
(2) The motor reverses below the swing rod, and the maximum frequency is less than 5Hz;
(3) When the swing bar is above, the motor rotates forward, the maximum frequency is 30Hz, and the reaction time is fast;
(4) When the swing rod is up or down, it cannot touch the limit point;
(5) When finding the zero point automatically, the swing amplitude should not be too large, which can quickly and accurately find the zero point;
(6) In the shutdown, the line will not loose, or is still taut state.
To realize the above functions of the power pay off rack, the PID function of Tianlang Weichuang vl6100 inverter can be used. First, find the zero point of the feedback rod (in the middle of the physical position, at this time, the PID input can be set to 50%), The feedback rod is connected with the feedback of PID, and the positive and negative rotation can be realized by the feedback rod's offset zero point. In order to realize other functions, the PID related parameters (PID gain, PID feedback, etc.) can be adjusted to achieve other functions.
