[0059] See also Figure 4 , 6 As shown, in the specific implementation scheme of the utility model, the first transverse seat assembly 22 is composed of a first transverse seat 221 and a first transverse ball screw track 222.

[0062] It should be particularly noted that the surface of the roller 242 is provided with a pattern. The patterned roller 242 is passive and has no power of its own. The roller 242 is supported only by two small bearings on the roller seat 241. When the two layers of non-woven fabrics are dragged by the traction roller of the cross-cutting machine, the roller 242 located at the bottom of the two layers of non-woven fabrics will passively rotate along with the non-woven fabrics.

[0065] Furthermore, the welding seat driving component 34 includes a second connecting seat 341 vertically connected to the second horizontal moving frame driving member 33, a vertically arranged driving cylinder 342, a mounting base plate 343 connected to the bottom of the driving cylinder 342, and a driving cylinder lifting plate 344 connected to the driving cylinder 342 and the ultrasonic welding gun 35. The driving cylinder 342 is suitable for driving the ultrasonic welding gun 35 to move up and down through the driving cylinder lifting plate 344.

[0066] See also Figure 5 , 6 As shown, in the specific implementation scheme of the utility model, the welding seat driving component 34 is composed of a second connecting seat 341, a driving cylinder 342, a mounting base plate 343 and a driving cylinder lifting plate 344.

When the driving cylinder 342 moves up and down, it drives the driving cylinder lifting plate 344 to move up and down. The driving cylinder lifting plate 344 is connected to the ultrasonic welding gun 35, thereby driving the ultrasonic welding gun 35 to move up and down.

[0067] Furthermore, the ultrasonic welding gun 34 includes an ultrasonic generator capable of generating ultrasonic vibration energy, a transducer horn connected to the ultrasonic generator, and an ultrasonic welding head connected to the bottom end of the transducer horn, and the ultrasonic welding gun 34 enables the ultrasonic working surface to be horizontally located above the ultrasonic welding head.

[0068] In this embodiment, the high-frequency signal generated by the ultrasonic generator generates a 35KHz vibration through the transducer horn, and then is transmitted to the ultrasonic welding head. When the ultrasonic welding head acts on the two layers of non-woven fabrics, high-frequency vibration is performed on the two layers of non-woven fabrics. The high temperature generated by friction melts the non-woven fabrics. By adjusting the amplitude of the transducer horn, the two layers of non-woven fabrics can be pasted together under a certain pressure. Since the roller 242 at the bottom of the non-woven fabric is engraved with a pattern, when the ultrasonic welding head acts on the non-woven fabric, the non-woven fabric melts at a certain melting point, so that a pattern will appear on the welding surface of the non-woven fabric.

[0069] Furthermore, the ultrasonic welding fixture structure also includes a fan 4 disposed on one side of the ultrasonic welding gun 34, and the fan 4 is used to control the wind speed of the energy during the welding process.
