Abstract

The invention discloses an ultrasonic sewing device for installing a non-woven fabric zipper, which relates to the field of ultrasonic sewing and comprises a mounting bracket, wherein an unreeling mechanism is arranged on the mounting bracket, a workbench is fixed on one side of the mounting bracket, two roller sets which are oppositely arranged are arranged on one side of the workbench, which is far away from the unreeling mechanism, the roller sets comprise two cooling rollers which are contacted with the upper end and the lower end of the non-woven fabric, and the ultrasonic sewing device further comprises a detection mechanism, wherein the detection mechanism is used for driving the two roller sets to reversely move so as to pull a sewing area. According to the ultrasonic sewing device for installing the non-woven fabric zipper, the detection mechanism can regularly drive the two roller groups to reversely move, so that certain opposite-direction pressure is applied to the two ends of a semi-finished product, and the cooling roller has two functions, namely, the upper end and the lower end of the semi-finished product are rapidly cooled, and the front end and the rear end of the semi-finished product are pressed with certain opposite tensile force.
