The ultrasonic sewing and embossing machine is also called an ultrasonic lace machine, and is efficient sewing and embossing equipment. The processing method is mainly used for edge sewing, welding, melt cutting, embossing and the like of synthetic fiber cloth, and the processed product has the characteristics of good water tightness, high production efficiency, no needle thread auxiliary material, smooth melt-cut surface, no rough edge, good hand feeling and the like. The method is widely applied to industries such as clothing processing, toy processing, food processing, environment-friendly non-woven bag processing, mask (cup-shaped mask, plane mask, three-dimensional mask and the like) processing and the like.

Structurally, an ultrasonic stitching and embossing machine generally comprises an operating platform, wherein a supporting arm is arranged on the operating platform, a stitching and embossing device is arranged on the supporting arm, and an ultrasonic device is arranged below the operating platform. When the sewing and embossing device works, after cloth pieces needing sewing and embossing are overlapped, the cloth pieces pass through the space between the sewing and embossing device and the ultrasonic device, the cloth pieces are pressed and held on the ultrasonic platform through the pattern wheel of the sewing and embossing device through operation, and under the action of traction force, the cloth pieces move forwards to finish sewing and embossing treatment.

The smoothness of the stitching embossing is one of important indexes, and has very important influence on ensuring the processing quality of products. During the processing, the overlapped cloth pieces need to be stably pulled forwards to move, and sewing and embossing are completed under the action of ultrasonic vibration when the overlapped cloth pieces pass between the embossing wheel and the ultrasonic platform. The existing sewing and embossing machine equipment generally draws the cloth piece through the drawing action provided by the floral whorl or arranges a separate drawing component in front of the floral whorl. However, the aforementioned pulling manner for the cloth piece has a significant problem of failing to provide a stable and proper pulling function for the cloth piece, which often causes the cloth piece to wrinkle, skew and the like during the forward movement, and finally causes the stitching and embossing effect to be difficult to meet the requirement of product quality.

On the other hand, since the thickness of the cloth piece to be processed is changed, the height of the knurling wheel and the clamping force of the traction assembly on the cloth piece need to be adjusted according to the type of the product to be processed, and therefore the above adjusting capability of the ultrasonic stitching embossing machine is also an important content affecting the use convenience of the equipment.
