A liquid capsule 12 is fixedly connected to the side wall of the slider 10, and the end of the liquid capsule 12 away from the slider 10 is fixedly connected to the side wall of one of the fixed plates 13. A one-way liquid inlet pipe 11 is installed at the end of the liquid capsule 12, and the liquid capsule 12 is connected to the nozzle 9 through a one-way liquid outlet pipe 17. The slider 10 passes through the through groove 16 so that the nozzle 9 is located directly above the embossing roller 7, a one-way liquid inlet valve is arranged in the one-way liquid inlet pipe 11, and a one-way liquid outlet valve is arranged in the one-way liquid outlet pipe 17. The liquid capsule 12 is made of rubber and has strong ductility. When discharging the lubricating oil, the nozzle 9 reciprocates above the embossing roller 7, so that the lubricating oil can be evenly squeezed onto the surface of the embossing roller 7.

[0024] In the utility model, the upper end of the mold body 3 is fixedly connected to two symmetrically arranged fixed plates 13, and a moving mechanism for moving the nozzle 9 is arranged between the two fixed plates 13.
