China Pigment Printing Fabric Factory introduces 3D embossing equipment. The technical embossing equipment usually includes an upper embossing roller and a lower embossing roller. The upper embossing roller is provided with patterned protrusions, and the lower embossing roller has a smooth appearance. When in use, the material that needs to be embossed is transported between the upper embossing roller and the lower embossing roller, and the upper and lower embossing rollers rotate relative to each other, and the protrusions press over the material to form patterns. Such embossing equipment can only press out the pattern of the plane structure, and cannot produce the pattern of the three-dimensional effect.

According to an aspect of the present invention, a device for 3D embossing is provided, comprising a first embossing roll, a second embossing roll and a vacuum suction device, the surface of the first embossing roll is provided with a plurality of first protrusions, the second The surface of the embossing roller is provided with a plurality of grooves. The protrusions cooperate with the grooves. The bottom of the grooves is provided with through holes. Through hole for suction.

Therefore, through the cooperation of the top protrusion and the top groove, a 3D three-dimensional embossing effect can be produced on the surface of the flat material. A through hole is arranged at the bottom of the first groove, and vacuum suction equipment is used for suction, so that the material located at the bottom of the first groove can protrude into the through hole to form a three-dimensional protrusion, which enhances the 3D three-dimensional effect of the material.
