Technical Field

[0001] The utility model relates to the technical field of leather embossing equipment, in particular to a leather embossing roller and a leather embossing machine with a prolonged service life. Background Art

[0002] When the leather embossing machine is in use, the height of the leather embossing roller is adjusted to emboss the leather surface. Long-term use will cause the leather embossing roller to be adjusted in height for a long time, and the surface of the guide rod lacks lubrication. Long-term friction leads to inaccuracy and reduces the service life. At the same time, the leather embossing roller lacks a good elastic pressing effect when embossing the leather, and the rigid pressing can easily cause damage to the leather.

[0003] A leather embossing machine for leather production (application number: 202121819583.2), comprising a base and a shell, the shell being fixedly connected to the upper end of the base, the upper end of the base being fixedly connected to a placing plate, a telescopic rod being fixedly connected to the shell, an embossing plate being fixedly connected to the lower end of the telescopic rod, an anti-deviation mechanism being fixedly connected to the outer surface of the embossing plate, slide grooves being provided on both sides of the placing plate, a stretching mechanism being provided under the placing plate, the motor rotates, the gear and rack meshing, so that the two sets of fixed rods move, and the wrinkles on the surface of the leather are arranged by the second roller to prevent embossing failure caused by wrinkles during embossing, the telescopic rod drives the embossing plate to emboss the leather, and during embossing, the anti-deviation mechanism first contacts the leather, and the embossing plate is pressed down, and the first roller first stretches and arranges the leather for a second time under the elasticity of the first spring to prevent leather wrinkles, and then the pressing plate contacts the leather, and the leather is pressed and fixed under the elastic action of the strong spring.
