S3: the first forward and reverse rotation motor 34 is started, the first forward and reverse rotation motor 34 drives the lead screw 32 to rotate, the lead screw 32 drives the displacement block 35 and the transmission air cylinder 36 to move forwards or backwards, so that the position of the punching head 37 is adjusted according to the punching position of the upper end of the carbon fiber tube 5, meanwhile, the second forward and reverse rotation motor 384 drives the transmission gear 385 to rotate clockwise, the transmission gear 385 drives the support plate 381 to move backwards through the fixed tooth seat 386, the support plate 381 is inserted into the Y-shaped groove after penetrating through the carbon fiber tube 5, the connection rod 388 is abutted to the inner top wall of the carbon fiber tube 5 at the moment, rectangular support can be applied to the inner top wall of the carbon fiber tube 5 through the connection rod 388 and the adjustable expansion plate 387, the punching head 37 is driven to move downwards through the transmission air cylinder 36 and the carbon fiber tube 5 is punched, in addition, the U-shaped receiving hopper can be formed through the support plate 381 and the two adjustable expansion plates 387 at the upper end of the support plate 381, and the waste materials punched on the carbon fiber tube 5 can be collected through the receiving hopper.

S4: after the carbon fiber tube 5 is blanked, the transmission cylinder 36 drives the blanking head 37 to retract and reset upwards, the second forward and reverse rotation motor 384 drives the transmission gear 385 to rotate anticlockwise, the transmission gear 385 drives the supporting plate 381 to move towards the front side through the fixing tooth holder 386 and is drawn out of the carbon fiber tube 5, then the carbon fiber tube 5 is driven to move towards the left side through the chain plate conveying belt 21, the linkage block 267 moves out of the fixing block 268 at the moment, then the sliding block 262 drives the arc-shaped rod 263 and the linkage block 267 to reset under the action of the contraction spring 266, so that the limiting effect on the carbon fiber tube 5 is relieved, and the carbon fiber tube 5 is convenient to take down.

S5: the above steps are repeated to complete the sequential blanking operation of the plurality of carbon fiber tubes 5.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
