Specifically, a notch is formed in the middle of the top of the lifting slide block 5, a ball head connected with a spherical hinge is installed in the notch, and a ball seat part connected with the spherical hinge is machined and installed and fixed to the lower end of a piston rod of the adjustable cylinder 1. The spherical hinge connection (also called spherical joint connection) mainly depends on the angular displacement of the ball head to absorb or compensate the transverse displacement in one or more directions, so that the transmission requirement of driving force can be met, a certain amount of displacement can be allowed to occur at the matching part, and the problem of blocking caused by position deviation due to rigid connection is avoided.

The lifting slider 5 is provided with a mounting substrate 6, and the mounting substrate 6 is fixedly connected with the lifting slider 5 by a plurality of screws. A platen base 14 is hinge-mounted to the front of the bottom of the mounting board 6, a spline 13 is mounted to the lower part of the mounting board 6, and a platen 7 that rotates in synchronization with the spline 13 is mounted to the platen base 14.

A carrier roller 23 is also arranged below the press roller 7. In practice, the entire embossing stitching device is mounted on a support, which in particular comprises a support base 24 fixedly connected to the operating table of the machine, on the support base 24 there are mounted support arms, on which there are mounted transverse arms, on the ends of which the embossing stitching device is mounted.

Thus, a window is provided in the support floor 24, the idler 23 being mounted below the window, the top portion being exposed to a certain height from the window. In order to ensure the drawing effect, the carrier roller 23 is a metal roller, and the press roller 7 is a rubber roller, so that sufficient clamping force and friction traction force are provided for the cloth piece.

The compression roller 7 is matched with the carrier roller 23 to clamp the overlapped cloth pieces, and the compression roller 7 rotates to clamp the cloth pieces between the compression roller 7 and the carrier roller and convey the cloth pieces forwards. The embossing wheel 13 is used for matching with the ultrasonic assembly 17 to roll the cloth pieces, and the cloth pieces are sewn (fused) together by local high temperature generated by high-frequency vibration and pressure provided by the embossing wheel 13 in the rolling process and form an embossing effect consistent with patterns on the surface of the embossing wheel 13.

The vibration platform that is located ultrasonic assembly 17 top is located and sets up in the window on supporting baseplate 24, and floral whorl 13 is pressed the cloth piece of coincide and is held on this vibration platform, and during processing, the compression roller 7 and the bearing roller 23 in the place ahead pull the cloth piece and move forward, and synchronous pivoted floral whorl 13 rolls the knurling to the cloth piece that the below passes through, and the high-frequency vibration that vibration platform provided is used for producing local high temperature, makes the position hot melt of cloth piece at the knurling fuse.

The hinge connection between the press roller base 14 of the press roller 7 and the mounting substrate 6 has the following functions: the height of the press roller 7 can be adjusted, and then the clamping force of the cloth piece can be adjusted. As shown in fig. 2, when the platen roller base 14 is tilted counterclockwise about the hinge shaft, the actual height of the platen roller 7 is reduced, so that the pressing force of the platen roller 7 on the fabric sheet is increased without changing the lifting range of the adjustable cylinder 1, whereas when the pressing force of the fabric sheet needs to be reduced, the platen roller base 14 should be tilted clockwise about the hinge shaft, and the height is raised. Initially, the center lines of both the platen roller 7 and the spline 13 may be made equal in height, and the adjustment may be performed by the adjustment mechanism.
