Embodiment Construction

[0037] The present invention provides a cold ironing device and method that saves cold ironing foil. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] see figure 2 , which is a structural schematic diagram of the cold ironing device provided by the present invention for saving cold ironing foil. like figure 2 As shown, the cold ironing device for saving cold ironing foil includes a foil supply roller 101, a foil receiving roller 102, a rubber roller 104, an embossing roller 105, a power roller 106, an adjustment mechanism 107, a controller (not shown in the figure) and bracket (not shown). The foil supply roller 101 , foil take-up roller ...

Abstract

The invention discloses a cold wave device and a method for saving cold wave foils. The cold wave device comprises a foil supply roller, a foil withdrawing roller, a rubber roller, an impressing roller, a motive power roller, a regulating mechanism, a support frame and a controller, wherein rubber cloth and rubber cloth interleaving paper in the shape corresponding to patterns to be transferred are arranged on the rubber roller, and the rubber cloth covers the rubber roller and the rubber cloth interleaving paper. According to the invention, the rubber cloth interleaving paper in the shape corresponding to the patterns to be transferred is arranged on the rubber roller, when the part of the rubber roller without the rubber cloth interleaving paper rotates to a position in press fit with the cold wave foils, the motive power roller tightly clamps the cold wave foils so that the conveying of the cold wave foils between the rubber roller and the impressing roller stops. Meanwhile, the length of a cold wave foil supply part is prolonged by the regulating mechanism, and the length of a cold wave foil withdrawing part is shortened by the regulating mechanism, so when the cold wave foils do not need to be impressed on the paper, the transferring of the impressing part of the cold wave foils stops, the paper feeding speed, the foil supply speed and the foil withdrawing speed cannot be influenced, the production efficiency is ensured, and the cold wave foils are saved.

Description

technical field [0001] The invention relates to the technical field of hot stamping, in particular to a cold stamping device and method for saving cold stamping foil. Background technique [0002] With the improvement of people's living standards, better requirements are put forward for the packaging of products, and the packaging design is becoming more and more exquisite. Hot stamping technology can improve the surface effect of packaging products. In recent years, hot stamping technology has developed rapidly, but for the small text, lines and dots on packaging products, hot stamping technology cannot meet the requirements, and hot stamping technology needs to be heated and pressurized. It consumes a lot of energy and has some defects in itself. Cold foil stamping technology is the first new technology achievement applied in the European and American printing industry in recent years. It can directly realize cold stamping on the basis of existing printing equipment, and ...
