Curing device and method and flexible printing machine comprising curing device

Abstract

The invention discloses a curing and method and a flexible printing machine comprising the curing device. The technical problem that the curing effect is poor or the curing precision is not maximizedin a timely manner is solved. The curing method is characterized in that a micro-control unit controls a motor to be started up at a preset frequency, when the motor is started up, a rotary shaft of the motor drives a connecting rod to rotate, then the connecting rod is in transmission connection with a movement rod, thus the movement rod drives a center part of a fan-shaped protection case to rotate, so that friction occurs between the outer surface of the center part and a cleaning sponge mat on the inner surface of a semi-condensation shell. In this way, the cleaning effect is achieved, thecuring effect is guaranteed in a timely manner, the curing precision and efficiency are improved, and the situation that a curing lamp tube or protection shell is not replaced until the curing effectis poor, resulting in low production efficiency is avoided. In addition, the protection shell avoids the situation that the curing lamp tube is likely to be contaminated is avoided, and the protection shell can be cleaned in a timely manner, thereby reducing the production cost and increasing the production benefit.

Description

technical field [0001] The invention relates to the field of flexographic printing, in particular to a curing device, a curing method and a flexographic printing machine including the curing device. Background technique [0002] Flexographic printing, also often referred to as flexographic printing, is a printing method that uses a flexographic plate to transfer ink to the flexographic roller through an anilox roller. At present, in the market, the flexographic printing industry adopts water-based ink thermal curing for printing curing. The thermal curing methods used in the drying system include: electric heating, oil heating, and steam heating. The traditional equipment parameters are usually: the printing speed is 300m / min; the color registration accuracy is ±0.1mm; the base material is non-woven fabric, PET / PET, paper, etc. Traditional curing methods require continuous supply of heat energy, which results in a large amount of waste emissions. For example, the thermal c...

Problems solved by technology

[0004] One of the objects of the present invention is to provide a curing device, which can protect the curing lamp and clean the protective shell of the curing lamp at a preset frequency, so that the curing effect can be guaranteed in time, and the curing accuracy and efficiency can be improved without waiting for curing to occur. Only replace the curing lamp or protective case when the effect is not good, resulting in low production efficiency

[0005] The second object of the present invention is to provide a curing method, which can protect the curing lamp tube and clean the protective shell of the curing lamp tube according to the preset frequency, so that the curing effect can be guaranteed in time, and the curing accuracy and efficiency can be improved without waiting for curing to occur. Only replace the curing lamp or protective case when the effect is not good, resulting in low production efficiency
