About parameter settings of high roll to roll coating machine





Generally speaking, the speed of high roll to roll cooling machine is 100-400m/min, which can be set according to the required running speed. Touch the "main roll speed setting" key, and the parameter input screen will appear, where you can enter the target value.

The running speed of the main roll is displayed in the winding flow chart of the main screen. When the main roll needs to run at a fixed speed, the corresponding value must be entered in the "main roll speed setting". In the zero speed tension state, press the "winding stop" button on the operation panel, and the main roll will automatically accelerate to the set speed. Press the "main roll acceleration" and "main roll deceleration" buttons, change the lock, and the main roll runs at a new speed.

According to the manufacturer of vacuum coating equipment, the unwinding tension is divided into manual tension and automatic tension. The manual tension is the percentage of the torque output of the unwinding motor. The automatic tension is in "kg", and its operation status is carried out according to the mode selected by the selector switch "automatic / manual". △ and ▽ are used to adjust the inching value of "unwinding tension setting".

Initial winding diameter of unwinding: this value is the measured value of the initial winding diameter when the unwinding starts to run. It must be correct to ensure the stability of the tension when the winding system starts to run. Unit: mm

Rewinding diameter reset: after entering the accurate value of "rewinding initial diameter", the button must be pressed to run the system for identification and confirmation, and make it consistent with the display of "rewinding diameter".

The left parameter setting simulation key "unwinding stop diameter" can set the machine to automatically slow down and stop in advance when the unwinding diameter reaches the predetermined value. According to the manufacturer of vacuum coating machine, the on key is in "off" state, i.e. red state, and this function is invalid.

On the operation interface of the vacuum coating machine, there are winding parameter setting simulation keys and function conversion keys, including winding direction, tension setting, initial winding diameter tension state selection, tension reduction multiple, etc. The setting method is the same as expanding.

The winding tension reduction factor represents the rate of change of tension with the increase of winding diameter. This value is positive, and the winding tension decreases with the increase of winding diameter. The real-time value of tension is f=f0*[1-k (1-d0/d)], where F0 is the set tension, K is the reduction factor, d0 is the hollow winding diameter, and D is the real-time value of winding diameter. When k is set to 0, the winding tension is constant.

The "tension" of the winding position of the vacuum coating machine is the real-time value of the tension in the winding process. "Coil diameter" is the real-time value of coil diameter during winding.

The "△ tension synchronous adjustment ▽" above the winding diagram of the vacuum coating machine is used to increase or decrease the tension value of unwinding and unwinding at the same time.
