[0028] How it works

[0029] The motor drives the screw to rotate, and the screw drives the wire tube to move. The carbon fiber tow is wound on the air shaft through the guide roller. The winding direction is changed by the PLC controller. The signal of the change of direction is obtained by the position detection switch. The position detection switch is set just below the slide. When the slide passes above the position detection switch, the position detection switch transmits the signal to the PLC control, and the PLC controller controls the motor to rotate in the opposite direction.

[0030] The position detection switch is movably arranged on the switch slide rail. When a shorter winding length is required, the position detection switch is moved to an appropriate length.

[0031] The PLC series is Mitsubishi FX3U. The position detection can be purchased on the market. The position signal can be converted into an electrical signal. There is no restriction on the model.

[0032] PLC control principle:

[0033] Press the start switch X0, Y0 is self-locked and energized, and the screw motor rotates forward. When the slider moves to the top of the position detection switch X1, the normally closed X1 is disconnected and the normally open X1 is closed. At this time, Y1 is self-locked and energized, the screw motor stops rotating forward and starts to reverse. When the slider moves to the top of the position detection switch X2, Y0 is connected again and it starts to rotate forward again.

[0034] When forward or reverse rotation is normal (Y0 or Y1 is turned on), but the winding motor is abnormal (Y2 is closed), the auxiliary relay M0 turns on the timer. After two minutes, it is proved that there is a winding failure, and the alarm Y3 turns on the alarm.

[0035] In some embodiments, see Figure 2 As shown, a dimension bar is provided on the back side of the switch slide rail 13. The dimension bar is used as a reference when moving the position detection switch to achieve accurate movement.

[0036] In some embodiments, see Figure 1 As shown, the movable roller frame 5 is provided with a slide mounting plate, a vertical side plate, and an inclined side plate;

[0037] The slide mounting plate is mounted on the slide 4 by bolts; at least one guide roller 6 is rotatably mounted on the vertical side plate; at least three guide rollers 6 are rotatably mounted on the oblique side plate; the included angle between the vertical side plate and the oblique side plate is 120 to 160 degrees. Four guide rollers are provided to prevent the wound carbon fiber tow from being entangled or knotted.

[0038] In some embodiments, see Figure 1 As shown, screw guide rails 3 are provided at both ends of the screw rod 14, the slide 4 is movably mounted on the screw guide rails 3, and the screw guide rails 3 are fixed to the screw rod frame 2 by screws.

[0039] In some embodiments, see Figure 1 As shown, the output end of the PLC controller 10 is also connected to the winding motor 9 and the alarm 11, and the alarm is used to alarm when the winding motor fails.

[0040] In some embodiments, see Figure 3 As shown, both ends of the screw rod frame 2 and the switch slide rail 13 are installed on the side plate 1.
