[0007] Preferably, the upper end of the moving plate is fixedly connected with a U-shaped block, and the lower end of the rotating rod is rotatably connected in the U-shaped block.

[0008] Preferably, the side wall of the fixed plate is fixedly connected with a motor, and the output shaft end of the motor is fixedly connected to the end of the drive rod.

[0009] Preferably, the lower end of the threaded rod passes through the lower end of the rotating plate and is rotatably connected to it, and a fixing block is fixedly connected to the lower end of the threaded rod.

[0010] Preferably, the upper end of the printing head is fixedly connected to two symmetrically arranged vertical rods.

[0011] Preferably, the upper end of the printing head and the lower end of the moving plate are elastically connected by two symmetrically arranged springs, with the two springs respectively sleeved on the two vertical rods.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting up a moving mechanism, during continuous printing, the output shaft of the drive motor rotates, which drives the drive rod to rotate. This causes the rotating plate to rotate around the drive rod as an axis, which in turn drives the slider, crossbar, and drive rod to rotate around the axis. This pulls the rotating rod and U-shaped block to move back and forth, which in turn drives the moving plate and printing head to move back and forth. When it is necessary to adjust the downward movement distance, the rotating fixed block drives the threaded rod to rotate, which drives the slider connected to it to move. This adjusts the distance between the slider and the drive rod, adjusts the rotation radius, and realizes the adjustment of the downward movement distance. This facilitates printing on products of different thicknesses and improves the processing efficiency of the device.

[0014] 2. By setting up a vertical rod, a spring, and a printing head, during printing, when the printing head moves down to contact the product surface, the pressure on the printing head will push the vertical rod upward, thereby squeezing the spring and compressing it. This buffers the printing head and avoids excessive impact force that could damage the product. Attached Figure Description
