Description

Technical Field

[0001] This invention relates to the field of hot stamping machine technology, specifically a green printing hot stamping machine. Background Technology

[0002] Hot stamping is an important decorative process in green printing. It involves transferring metallic foil from hot stamping paper to the surface of printed materials by heating the hot stamping plate, enhancing the product's aesthetics and added value. However, existing green printing hot stamping machines use hot stamping paper rollers with a fixed height. Different product specifications require different tension and height from the hot stamping paper rollers, and the fixed rollers cannot be adapted, easily leading to wrinkles, tears, or uneven hot stamping pressure (incomplete hot stamping in some areas). Furthermore, the hot stamping plate is fixed to the heating base with multiple bolts, requiring individual bolt removal for replacement, which is very time-consuming and labor-intensive. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a green printing hot stamping machine that features adjustable hot stamping paper roller height and efficient hot stamping plate replacement, thereby facilitating different types of hot stamping work on different products and solving the problems mentioned in the background art.

[0011] Preferably, the third motor is a geared motor. Beneficial effects

[0012] Compared with the prior art, the present invention provides a green printing hot stamping machine, which has the following beneficial effects: 1. This green printing hot stamping machine uses a third motor to drive the first shaft pin to rotate, causing two rotating bars to rotate relative to each other around the third shaft pin. This pushes the top plate and movable rod to rise and fall along the fixed tube, thereby adjusting the height of the hot stamping paper roller and the hot stamping plate. This adapts to printing products of different thicknesses and avoids wrinkles or uneven pressure on the hot stamping paper.

[0013] 2. This green printing hot stamping machine uses a rotating threaded rod to drive the second gear to move, which in turn drives the first gear and the rotating rod to rotate. This causes the rotating bar to disengage the clamping rod from the U-shaped block, allowing for quick removal and replacement of the hot stamping plate. This eliminates the need to disassemble multiple sets of bolts, significantly improving replacement efficiency and adapting to different types of hot stamping needs. Attached Figure Description
