Bottle cap bronzing usually includes: top bronzing and side bronzing. The former belongs to the flat bronzing, and the latter belongs to the curved bronzing. Flat hot stamping only has the up and down movement of the hot stamping head. After the hot stamping plate imprints the hot stamping paper on the top of the bottle cap, the hot stamping paper in the graphic area will be transferred to the surface of the product. In the selection of bronzing machines, flat bronzing machines with a single table are more common. We only need to manufacture one fixture to fix the caps for continuous bronzing. However, this kind of hot stamping machine requires a longer preparation time and the efficiency of manual handling is low, it is difficult to achieve the desired output. Therefore, installing a turntable table similar to a pad printing machine on the flat bronzing machine table greatly makes up for this defect. Usually, the turntable table can be installed with 10 to 20 workstations, and multiple products can be installed at one time for sequential bronzing, which saves preparation time and greatly improves production efficiency.
In addition to the pressing action of the hot stamping head, the curved surface hot stamping also has the lateral movement of the worktable. The gear at the end of the fixture and the rack of the worktable are driven, and the bottle cap will roll against the surface of the hot stamping plate to achieve hot stamping. Surface hot stamping has high requirements for the production of fixtures, especially when hot stamping parallel lines, the rotation coincidence of the hot stamping fixture directly affects the accuracy of the combination of parallel lines.
