Painting equipment and technology of magnetic pigment

Abstract

The invention discloses painting equipment of magnetic pigment. A painting device, a magnetic orienting device and a magnetic setting device used for setting of the magnetic pigment are sequentially arranged in the forward direction of magnetic pigment painting material, wherein the painting device is used for continuously painting the painting material with the magnetic pigment, and the magnetic orienting device is used for orienting the magnetic pigment. According to the painting equipment, the magnetic pigment can be continuously and rapidly painted and can be continuously, rapidly and magnetically oriented and set, production efficiency is improved, accuracy of magnetic patterns is improved, and product cost is reduced. The invention further discloses a painting technology, a sheet coated with the magnetic pigment is sequentially magnetically oriented and set and completely solidified through a drying oven, and the sheet having a stereoscopic and dreamlike visual effect is formed. The method can greatly increase production speed of the magnetic pigment and reduce production cost, and the manufactured sheet is excellent in magnetic stereoscopic effect, the magnetic patterns are distinct, and accuracy is high.

Description

technical field [0001] The invention relates to the field of magnetic pigment coating equipment and technology, in particular to a magnetic pigment coating equipment and coating process. Background technique [0002] At present, magnetic pigment coatings are widely used in material decoration, anti-counterfeiting treatment and other fields because they can change the direction or arrangement direction of magnetic pigments by using a magnetic field, which can produce three-dimensional psychedelic visual effects on the surface. However, after the magnetic pigment coating is painted, it must go through a magnetic field and stay for a certain period of time to produce a three-dimensional effect, and this effect will also promote the disappearance of leveling before it is set, which makes the application of magnetic pigment coating many processes, and the production speed is extremely slow. Moreover, it is necessary to use multiple devices to work at the same time to meet the dem...

Problems solved by technology

However, after the magnetic pigment coating is painted, it must go through a magnetic field and stay for a certain period of time to produce a three-dimensional effect, and this effect will also promote the disappearance of leveling before it is set, which makes the application of magnetic pigment coating many processes, and the production speed is extremely slow. Moreover, it is necessary to use multiple devices to work at the same time to meet the demand of production volume, which not only takes up space, but also costs money. Therefore, the magnetic pigment paint coating device has the defects of low production efficiency and high cost

In addition, magnetic molds have always been difficult to make, high in cost, and low in accuracy, which seriously affects the development of the magnetic pigment effect ink coating market.

[0003] When producing products with magnetic pigment effects, it is generally screen-printed or sprayed on a single sheet (or intermittently and continuously screen-printed), and then moved out and placed on a magnetic mold for a certain period of time to produce a three-dimensional effect. Because the magnetic effect will tend to level and disappear before it is set, Therefore, the magnetic mold cannot be removed before the coating is completely cured, so that there are many processes when applying the magnetic coating, and the production speed is extremely slow, and it is necessary to use multiple devices to work at the same time to meet the demand for production volume, which not only takes up space, but also reduces production costs. Therefore, it is the development direction of the industry to develop a new production process to make the product faster and the pattern clearer.
