Problems solved by technology

[0002] Due to the special drying method of mirror silver ink, the drying method of printing mirror silver ink on PC, PET and acrylic sheets is usually as follows: use traditional industrial hair dryer to dry, and use hot air to make the solvent in the ink quickly. Volatile, does not erode the mirror silver, and maintains a high brightness of the mirror silver to achieve a mirror effect. This method cannot control the blowing temperature and wind speed of the hair dryer. It is often necessary to continuously adjust the height of the hair dryer and the high and low temperature fans to achieve the mirror effect.
[0003] In addition, the existing method has poor controllability, so it is difficult to control the drying time of the ink, and the efficiency is low. Moreover, the existing process does not have corresponding molding process parameters, and the inspection is carried out by artificial inspection, which has relatively large unstable factors. Quality and stability are not guaranteed

Embodiment Construction

[0023] Embodiments of the present invention are described in detail below in conjunction with the accompanying drawings:

[0024] Such as Figures 1 to 4 As shown, the special drying equipment is provided with three air ducts, and each air duct has an air inlet, and heater 1, heater 2, and heater 3 are respectively installed in the air ducts at the fan air inlets of the three air ducts; The three air ducts are installed side by side and extended to the outlet end of the air duct and fixed side by side.

[0025] The three air ducts have the same structure, but heaters with different powers are used. Heater 1, heater 2, and heater 3 are respectively composed of several resistive heating elements fixed on the substrate of the heater device; the heater adopts resistive heating The way;

[0026] Taking one of the above three air ducts as an example, the structural diagram of the heater 1 is as follows: figure 2 As shown; the heater 1 includes three resistive heating elements 11...

Abstract

The invention discloses drying equipment for mirror silver ink and a process thereof. The process is characterized in that special drying equipment provides a hot air drying area that an initial end section is a low temperature area, an intermediate section is a high temperature area, and a tail end section is a low temperature area, and the three sections are continuously connected; and a drying method for heating and sectional control of sheets with ink printed on the surfaces by low temperature-high temperature-low temperature sectionalization is adopted to dry the ink on the surfaces of the sheets. The adoption of a mode of sectional heating and sectional control of low temperature at both ends and high temperature at the intermediate position has the advantages that a drying mode that the prior process adopts a human observation mode for inspection, no corresponding formed process parameters exist and the human observation mode is adopted for inspection is improved; a heater device is arranged at an air inlet of a blower to make the temperature of blown air reach certain process requirement; and a cylindrical blast nozzle is used at an air outlet to maintain certain wind pressure to ensure the uniformity and stability of air volume, thereby ensuring that a solvent in the ink is quickly volatilized to obtain the mirror effect with higher brightness.

Description

technical field [0001] The invention relates to a drying process for mirror-surface silver ink, in particular to a drying equipment for mirror-surface silver ink, which is suitable for printing carriers such as PC, PET, and acrylic, and a process thereof. Background technique [0002] Due to the special drying method of mirror silver ink, the drying method of printing mirror silver ink on PC, PET and acrylic sheets is usually as follows: use traditional industrial hair dryer to dry, and use hot air to make the solvent in the ink quickly. Volatile, does not erode the mirror silver, and maintains a high brightness of the mirror silver to achieve the mirror effect. This method cannot control the blowing temperature and wind speed of the hair dryer. It is often necessary to constantly adjust the height of the hair dryer and the high and low temperature fans to achieve the mirror effect. [0003] In addition, the existing method has poor controllability, so it is difficult to con...
