Cooling flat-type bronzing machine with three colored tapes

Abstract

The invention discloses a cooling flat-type bronzing machine with three colored tapes. An unwinding device, a winding device and a delivery roll between the unwinding device and the winding device arefixedly arranged on a main frame body. The delivery roll is driven by a motor for delivering the paper to be bronzed. Three bronzing parts and a cooling part are fixed sequentially on the main framebody in the direction of moving of the paper to be bronzed. Unwinding shafts and winding shafts are arranged on upper portion of the bronzing parts in parallel, and first separating rollers and secondseparating rollers are arranged on the lower portion of the bronzing parts, material drawing rollers are arranged under the winding shafts, and heating units and drying units are arranged in the bronzing parts. A hot stamping machine unit with three heating devices and one cooling device is adopted, the bronzing speed is accelerated, automatic moving marking function is achieved, the overprintingaccuracy is higher, and is generally 40-60 meters per minute, the number of bronzing paper is reduced, vibration is extremely small, and the noise is small. Because heat conduction, heat absorption and melting of a hot melt adhesive take a certain time, the hot stamping effect of flat-type bronzing machine is better than that of other machines, and the efficiency is improved.

Description

technical field [0001] The invention relates to a thermal transfer printing device, in particular to a three-color belt cooling flat stamping machine. Background technique [0002] With the improvement of people's material life and spiritual life, people pay more and more attention to the beautification of the surface of books. Traditional printing technologies such as color printing can no longer meet people's needs. As a result, various new printing processes have emerged. Printing machines with different functions were produced, such as hot stamping machines. Hot-melt glue is coated on the side of the hot stamping paper that is in contact with the paper. At a certain temperature, the glue melts and combines with the paper under proper pressure to achieve hot stamping transfer. However, the existing hot stamping machines are inconvenient to operate, have complex and heavy structures, run slowly, and have low work efficiency. The traditional hot stamping machines need to r...

Problems solved by technology

However, the existing hot stamping machines are inconvenient to operate, complex and bulky in structure, slow in operation, and low in work efficiency. The traditional hot stamping machine needs to run three times repeatedly when printing three kinds of colors, and the work efficiency is low and the color registration accuracy is poor.
