Multifunctional integrated intaglio printing press and machining process thereof

Abstract

The invention provides a multifunctional integrated intaglio printing press which comprises an unreeling device, an introduction deviation rectifying device, a double-traction device, a printing unit, an edge cutting device, a belling device, a die cutting device, a soft pack cutting device and an automatic stacking paper collecting device. A first traction guide device, a gilding device, a holographic positioning ironing device, the belling device, an online detection device and a second traction guide device are sequentially arranged between the printing unit and the edge cutting device. The printing unit comprises at least nine gravure printing devices, and the multiple gravure printing devices are combined to form multi-color continuous gravure. The first traction guide device and the second traction guide device are provided with stepless speed regulating mechanisms to control the tension and the linear speed of paper passing the gilding device, the holographic positioning ironing device and the belling device at high accuracy, and accuracy control and position control over hot stamping, laser holography transfer printing and raised ironing of cigarette packs are achieved at the same time. The invention further provides a machining process of the multifunctional integrated intaglio printing press.

Description

【Technical field】 [0001] The invention relates to printing equipment, in particular to a multifunctional integrated gravure printing machine and its processing technology. 【Background technique】 [0002] At present, in the printing of cigarette labels in the packaging industry, most of them use paper or paper-plastic dual-purpose gravure printing machines. Since the gravure printing machine is easier to achieve environmental protection and pollution-free production from printing raw materials, materials, auxiliary materials to printing technology, processes, etc., to achieve the purpose of "green printing", so the proportion of cigarette label printing is increasing. The application method also ranges from simple gravure printing to in-line cross-cutting in gravure printing, in-line die-cutting, and in-line embossing die-cutting in gravure printing. [0003] However, the process flow of most cigarette labels in domestic cigarette label printing companies is basically: plate...

Problems solved by technology

However, with the development and improvement of electronic technology, the traditional mechanical transmission technology is becoming less and less suitable for the needs of modern production. When changing products (different sizes), it is necessary to change gears, paper guide shafts, etc., which is a waste of time. Second, because the sizes of various products sometimes have very small differences, the size of the gears is easy to identify, and the diameter of the paper guide shaft is difficult to distinguish by eye. For modern production with higher and higher precision requirements, it is difficult to meet the control requirements.

At the same time, due to some weaknesses of mechanical transmission, the mechanical transmission itself will produce a large cumulative error in the initial process of production, and it is becoming more and more urgent to seek new control methods
