Problems solved by technology

[0002] In the existing longitudinal slitting machine, the traditional unwinding frame is fixed. During the slitting process, the diameter of the base material of the unwinding shaft decreases continuously, so that the distance between the surface of the base material of the unwinding shaft and the unwinding guide roller continues to increase. , the L distance in the figure, that is, the suspending length of the substrate is getting longer and longer, the airflow generated during the high-speed unwinding process makes the substrate shake and the tension is unstable, and it cannot work normally, so that the cutting speed cannot be increased

Embodiment 2

[0019] Example 2 as figure 1 As shown, the detection photoelectric head 5 is fixed on the unwinding guide roller 4? ? ,

[0020] The detection photoelectric head 5 is electrically connected to the variable-range automatic logic controller PLC, and the variable-range automatic logic controller PLC is electrically connected to the transmission servo motor 8. The servo motor 8 is connected to the ball screw 7 through the bevel gear 9, and the ball screw Pay 7 to be connected with sliding track 6 transmissions by screw nut. The nut of the ball screw 7 is fixedly connected with the sliding track bracket. There is a pulley at the bottom of the sliding track bracket. The pulley slides on the sliding track 6 to drive the fixed discharge rack 1 and the unwinding air shaft 2 on the sliding track bracket. Cut substrate 3 moves.

[0021] When unwinding, through the detection of the photoelectric head 5, the electrical signal is transmitted to the PLC to compare with the original set v...

Description

technical field [0001] The invention relates to a base material longitudinal slitting device, in particular to an automatic moving unloading rack of the base material longitudinal slitting device. Background technique [0002] In the existing longitudinal slitting machine, the traditional unwinding frame is fixed. During the slitting process, the diameter of the base material of the unwinding shaft decreases continuously, so that the distance between the surface of the base material of the unwinding shaft and the unwinding guide roller continues to increase. , the L distance in the figure, that is, the suspending length of the substrate is getting longer and longer, the airflow generated during the high-speed unwinding process makes the substrate shake and the tension is unstable, and it cannot work normally, so that the slitting speed cannot be increased. Contents of the invention [0003] The purpose of the present invention is to provide a design method for the automati...
