along with the increase of the amount of the non-woven fabric wound by the winding drum 5, the power roller 7 and the mounting plate 9 are driven to move upwards, so that the first electric contact piece 37 moves upwards, when the first electric contact piece 37 abuts against the second electric contact piece 36, the electromagnet 39 is electrified (the electromagnet 39 and the first electric contact piece 37 and the second electric contact piece 36 supply power independently), the electromagnet 39 generates repulsion force on the magnetic block 41 when being electrified, so that the magnetic block 41 and the clamping block 42 slide, the clamping block 42 can be clamped into the clamping groove 43, the sleeve 44 is connected with the fourth bevel gear 22, the sleeve 44 can rotate, because the rack plate 27 and the reciprocating screw rod 26 cannot rotate under the action of the supporting wheel 28, the sleeve 44 rotates, the rack plate 27 can be driven to move by the reciprocating screw rod 26, the rack plate 27 moves at the moment, gear teeth on the rack plate 27 are not meshed with the first gear 29, along with the winding of the non-woven fabric, the contact area between the first electric contact piece 37 and the second electric contact piece 36 is increased, the corresponding rack plate 27 also moves, when the rack plate 27 is meshed with the first gear 29, the clamping teeth 31 at the moment clamp the second gear 30 and drive the second gear 30 to rotate, the second gear 30 rotates to drive the triangular rod 4 to rotate, the triangular rod 4 rotates to drive the three winding drums 5 to rotate, the winding drum 5 which is wound is rotated to the lower right side, and the winding drum 5 on the lower left side rotates to the upper side but does not abut against the power roller 7;
the reason why the lower left take-up drum 5 rotates upward but does not abut against the power roller 7 is as follows: when the slider 33 (corresponding to a piston) moves downward under the elastic force of the first spring 35 and the gravity of the mounting plate 9, the damping hole 34 prevents the slider 33 from moving downward, so that the power roller 7 does not abut against the winding drum 5, and the first electrical contact piece 37 and the second electrical contact piece 36 still abut against each other;
when the triangular rod 4 rotates to coincide with the original position, the rack plate 27 is not meshed with the first gear 29 any more, the rack plate 27 still moves when the first gear 29 does not rotate any more, and the non-woven fabric can be cut off under the action of the hot cutter 25;
the sleeve 44 continues to rotate, the reciprocating screw rod 26 is reset, when the rack plate 27 is reset, the rack plate 27 is meshed with the first gear 29 again, the latch 31 is no longer limited (similar to a ratchet) to the second gear 30, and thus the second gear 30 is static; correspondingly, at this time, the first electric contact piece 37 is separated from the second electric contact piece 36, the electromagnet 39 is powered off, the magnetic block 41 and the fixture block 42 can slide into the hollow block 38 under the action of the second spring 40, the fixture block 42 is separated from the fixture groove 43, the sleeve 44 does not rotate, finally the power roller 7 abuts against the winding drum 5, the winding drum 5 can be driven to rotate, and therefore the non-woven fabric can be wound, and automatic roll changing is achieved;
the staff only need lift the winding drum 5 after the rolling is accomplished off, install new winding drum 5 can, need not to stop the machine to can improve work efficiency.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
