Manufacturing equipment for anti-counterfeit traceable labels

Abstract

The invention discloses manufacturing equipment for anti-counterfeit trace labels. The equipment is provided with a paper feeding mechanism, a paper conveying mechanism, printing mechanisms, a polishing mechanism, a die cutting mechanism, a paper discharge mechanism and a paper collection mechanism; a control system, a dampening roller, an ink roller and printing plate rollers are arranged in eachprinting mechanism, the outer circumference of each dampening roller and the outer circumference of the corresponding ink roller are both in contact with the outer circumference of the correspondingprinting plate roller, an emulsification measuring instrument is arranged at one end of each printing plate roller, a dampening vibrator is arranged on one side of each dampening roller, and the outercircumference of each dampening vibrator is in contact with the outer circumference of the corresponding dampening roller; multiple spraying heads are arranged on one side of each dampening vibratorand connected with a water inlet pipe, a water pump is arranged on each water inlet pipe, and the water pumps and the emulsification measuring instruments are both electrically connected with the control systems. The control systems control the rotation speed of the water pumps to be decreased or increased according to emulsification values measured by the emulsification measuring instruments, sothat the water discharge amount of the spraying heads is decreased or increased in order to maintain the emulsification degree of ink in an appropriate range, and the label printing quality is improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a manufacturing device for an anti-counterfeiting traceability label. Background technique [0002] As we all know, the principle of lithographic printing is that water and ink are not compatible, and the emulsification of ink is inevitable. The so-called ink emulsification is the phenomenon that the ink is dispersed into immiscible water. There is no completely non-emulsified ink, and without moderate emulsification, a good ink transfer process in lithographic printing cannot be achieved, but excessive emulsification of the ink brings printing The danger is also very great. Excessive emulsification will cause the surface of the printed product to be light in color, not bright, the printed product dull, the dots will be blurred and deformed, the dots will have burrs, the surroundings will not be smooth, the imprint will be weak, the drying will be slow, the back of the printed ...

The so-called ink emulsification is the phenomenon that the ink is dispersed into immiscible water. There is no completely non-emulsified ink, and without moderate emulsification, a good ink transfer process in lithographic printing cannot be achieved, but excessive emulsification of the ink brings printing The danger is also very great

Excessive emulsification will cause the surface of the printed product to be light in color, not bright, the printed product dull, the dots will be blurred and deformed, the dots will have burrs, the surroundings will not be smooth, the imprint will be weak, the drying will be slow, the back of the printed product will be sticky and dirty, and the printing will be severely collapsed. , causing a large number of printed inks to be inconsistent in color, dirty, flowery, blind, and the strokes of the text are not beautiful, and the printing plate is not inked

Especially when printing anti-counterfeit traceability labels, improper emulsification of the ink will inevitably lead to blurred anti-counterfeit traceability patterns on the label paper, which cannot be recognized by anti-counterfeit traceability information identification equipment, and cannot achieve the effect of anti-counterfeit traceability
