Description

TECHNICAL FIELD

[0002] The non-woven fabric slitting machine is a kind of mechanical equipment for slitting wide non-woven fabric, paper, mica tape or film into multiple narrow materials, commonly used in papermaking machinery, wire and cable mica tape and printing and packaging machinery.

[0003] The ultrasonic cloth slitting equipment currently used includes a rack, a first cloth guide roller, a slitting mechanism, a pinch roller mechanism, a driving mechanism, an ultrasonic sewing mechanism for sewing the cut cloth strip, and a winding mechanism.The first cloth guide roller is rotatably installed on the rack, and the slitting mechanism is arranged on the rack and located between the first cloth guide roller and the pinch roller mechanism.The pinch roller mechanism is installed on the rack, and the driving mechanism is connected with the pinch roller mechanism.The ultrasonic sewing mechanism is installed on the rack and cooperates with the slitting mechanism.The winding mechanism includes a winding drive and a winding shaft, and the two ends of the winding shaft are rotatably supported on the rack and connected with the rack.

[0004] For the above-mentioned slitting equipment, since the bearing seat is installed on the rack, the two ends of the winding shaft are connected with the bearing seat, so when the winding drive works to drive the winding shaft to rotate, the cut cloth can be wound. The disadvantage of this equipment is that since the two ends of the winding shaft are connected with the bearing seat, the position of the winding shaft will not change, the central shaft torque is constant, the winding diameter is equivalent to the force arm, and the longer the force arm, the smaller the end force, therefore, the tension of the winding shaft to the cut cloth is reduced with the increase of the winding diameter, resulting in the loosening of the wound cloth. TECHNICAL SOLUTION

[0005] The utility model provides a kind of ultrasonic cloth slitting equipment, and the utility model can avoid the loosening of cut cloth in winding process.

[0006] The technical scheme for solving the above problems is as follows:

[0008] In the utility model, after the winding drive works, because the slitting cloth roller on the winding shaft cooperates with the winding roller, the winding roller generates driving force to the slitting cloth roller, so that the slitting cloth roller rotates, thereby continuously winding the slitting cloth, with the increase of the diameter of the slitting cloth roller, the slitting cloth roller generates upward force to the winding shaft, because the winding shaft is pivotally connected with the sliding block 12, and the sliding block is slidingly matched with the guide rod, therefore, when the winding shaft is subjected to the upward force, the winding shaft moves upward, the winding shaft transmits the upward force to the sliding block, and the sliding block moves upward along the guide rod.
