The utility model discloses a thermoprinting machine with a multidirectional translation function, and relates to the technical field of thermoprinting equipment. The device comprises a rack provided with a profiling moulding bed, a lifting unit is hung above the profiling moulding bed, the lifting unit is provided with a lifting support, and the bottom of the lifting support is connected with a heating hot stamping mould; a longitudinal moving unit and a transverse moving unit are arranged on the lifting support. Compared with the prior art, the utility model can solve the problem that the utilization rate of the hot stamping foil paper is extremely low due to the fact that the hot stamping foil paper after the hot stamping is finished has a large-area non-hot-stamping blank because the hot stamping foil paper can only be wound and unwound along a single direction when the traditional hot stamping equipment is used for hot stamping the foil paper.

Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping equipment, in particular to a hot stamping machine with a multi-directional translation function. Background Art

[0002] Hot stamping foil, also known as hot stamping foil or hot stamping film, is a special thin sheet material. It is mainly used in the hot stamping process. It uses the principle of heat transfer to transfer the pattern or text on the foil to the surface of the substrate. Therefore, it is widely used in the printing and decoration of paper, textiles, leather, plastic and other materials. Hot stamping foil usually has a layer of special adhesive that can fix the foil on the surface of the substrate during the hot pressing process. Since the pattern or text that needs to be hot stamped is mostly a star-shaped structure, and traditional hot stamping equipment can only rewind and unwind the hot stamping foil in a single direction when hot stamping, the hot stamping foil after hot stamping is like Figure 1 As shown, there are still relatively large areas of unstamped blank space between the stamping dots 101, which makes the utilization rate of the stamping foil extremely low in production, greatly increases the loss and waste of materials, and causes excessively high production costs. Utility Model Content
