[0027] This scheme is based on the problem that the current leather printing equipment proposed in the above background technology uses a lot of molds when hot stamping patterns, and usually processes continuously, and it is not convenient to load and replace molds, which affects the processing efficiency.

[0057] Working principle:

[0058] The present invention uses a driving component 2 installed on the side of the device frame 1 to rotate the fixed hand wheel 16 at the top to rotate the fixed screw rod 17 at the bottom to drive the fixed clamp 18 to fix and remove the middle printing steel roller 3, so that the printing mold installed on the printing steel roller 3 can be easily replaced, and the floating pressing plate 12 can be driven by the driving component 2 to move up and down, so that the leather can be clamped between the printing steel roller 3 for printing;

When the limiting groove housing 2101 rises to the limiting slider 216, it is limited by the limiting protrusion 2107, thereby sliding sideways to push the reset spring 2104, so that the thread on the lifting screw rod 215 is stuck in the screw rod clamping groove 2108, thereby fixing the position;

[0061] Among them, the required hot stamping mold is installed through the printing mold installation hole 302 on the printing steel roller 3, and the steel roller driving teeth 304 at both ends are coordinated with the driving chain 2075 to drive the printing steel roller 301 to rotate, and the disassembly hand pull rings 303 at both ends can pull the printing steel roller 301 out of the printing steel roller installation groove 19.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
