Description

Novel device for pressure-to-gold stamping of PP plate

Technical Field

The utility model belongs to the technical field of printing, and particularly relates to a novel device for pressure-to-hot stamping of a PP plate.

Background

Gold stamping is a special printing process without ink. The gold stamping refers to a process of stamping the electrochemical aluminum foil on the surface of a printing stock at a certain temperature and pressure. The gold stamping principle is that after a certain temperature and pressure, the color foil instantly adheres the patterns and characters of the plate on the surface of the plastic.

The existing hot stamping equipment is not ideal in temperature rising effect, the effect of uniform temperature rising is difficult to achieve, the phenomenon that the local temperature is too high or too low can still occur in the using process, particularly for PP plates, the hot stamping difficulty is higher, the requirements on temperature and pressure are higher, and therefore a novel device for hot stamping by changing the pressure of the PP plates is needed.

Preferably, the device also comprises a front guide roller and a rear guide roller, wherein the front guide roller is vertically arranged at the bottom end of the discharging roller; the rear guide roller is vertically arranged at the bottom end of the material receiving roller; the gold stamping roller is positioned between the front guide roller and the rear guide roller.

Preferably, the inner ends of the two oil pipes are close to each other and close to the midpoint of the oil inlet cavity.

Preferably, the diameter of the oil outlet hole is gradually increased from the outer side to the middle point of the oil inlet cavity.

Preferably, the heater is an electromagnetic heater.

Preferably, the periphery of the pressure roller is wrapped by a silica gel layer.

Preferably, the device further comprises a conveying belt, and the conveying belt is arranged on the other side of the pressure bearing roller.

(III) advantageous effects

The utility model provides a novel device for pressure-transfer hot stamping of a PP plate, which has the advantages of simple structure, convenience in operation, high working efficiency and good hot stamping effect. Neotype gilt roller structure makes heating oil more even in gilt roller inside distribution, heaies up through electromagnetic heater, and then heaies up heating fluid, and then realizes quick, the even intensification of roll body, and then has guaranteed that the heat that gilt roller sent is even, and the temperature stability has avoided local temperature too high or low excessively, has promoted gilt quality greatly. The method has the advantages that the hot stamping difficulty of the PP plate is higher, the effect of the method is excellent in the aspect of hot stamping of the PP plate, and the method has important significance in the development of hot stamping of the PP plate.
