Description

TECHNICAL FIELD

[0001] The present application relates to the field of green printing technology, more particularly to a green and environmentally friendly printing process and equipment. BACKGROUND

[0002] Green printing refers to the use of environmentally friendly materials and processes, with less pollution, resource and energy saving during printing, and printing preparation, printing process, drying process and post-treatment stage. Printing drying refers to the process of drying the ink on the printed matter. In the printing process, the ink needs to be dried quickly by heating or air drying, etc. so that the printed matter can be smoothly processed and packaged;

[0003] In the drying stage of the printed matter, a printing product dryer is usually used for drying the cloth, and the drying method of the dryer is usually a tunnel drying method. The so-called tunnel drying method is to make the hot air generated by the dryer flow up and down in the internal space of the tunnel-shaped housing, so that the hot air can fully dry the cloth. The main structure of the tunnel dryer includes a motor providing driving function, a transmission wheel driven by the motor, a conveyor belt driven by the transmission wheel, a tunnel-shaped housing erected above the conveyor belt, a hot air blower installed at the upper end of the tunnel-shaped housing, and a baffle installed below the hot air blower. After the hot air is blown out by the hot air blower, it flows up and down in the internal space of the tunnel-shaped housing by using the baffle, so that the printed matter above the conveyor belt can be effectively and fully dried. However, in actual use, the drying method of the traditional tunnel dryer still has the following problems.

[0004] The motor drives the transmission wheel to rotate, and the transmission wheel drives the conveyor belt to move, thereby transporting the printed matter. However, before the hot air blower of the tunnel dryer is started, the part of the surface of the printed matter cannot be in close contact with the conveyor belt due to the light weight of the printed matter, which can cause the conveyor belt to move and displace the printed matter, so that the printed matter cannot be evenly placed on the upper surface of the conveyor belt, thereby affecting the drying effect of the subsequent hot air blower.

[0005] When the traditional tunnel dryer of the prior art dries the printed matter on the conveyor belt, the hot air flow generated by the hot air blower flows up and down in the direction of the printed matter by using the baffle installed in the tunnel dryer. However, there is a gap between the baffle and the printed matter, which causes part of the hot air flow to escape from the direction of the printed matter, thereby reducing the utilization rate of the hot air flow generated by the hot air blower, and reducing the drying efficiency of the traditional tunnel dryer.

[0006] The conventional tunnel dryer in the prior art is still in a high-temperature state after completing the drying work of the printed matter, and the heat blower, the electric heating resistance wire and the tunnel shell are still in a high-temperature state, and the conventional tunnel dryer can only be naturally cooled by long-time standing, which is not safe and has low cooling effect.

An eco-friendly printing process based on the eco-friendly printing apparatus according to any one of claims 1 to 6, characterized in that, The specific steps of the printing process are: The green environmental protection printing equipment works, first, the printing is placed on the upper surface of the conveying belt (104), at this time, the CPU controls the first servo motor (310) and the second servo motor (311) drive, the first servo motor (310) and the second servo motor (311) move the side link (304) and the front link (306) to the horizontal plane parallel, at this time, the airflow blown by the micro fan (309) is perpendicular to the horizontal plane, so that the printing and the upper surface of the conveying belt (104) are closely attached, then the transport motor (105) drives the rotating shaft (102) to rotate, the rotating shaft (102) rotates to drive the transport gear (103) to rotate, the transport gear (103) rotates to drive the conveying belt (104) to move, the guide shaft (106) is in contact with the conveying belt (104) on the bottom side of the conveying belt (104), the guide shaft (106) plays a guiding and supporting role of the conveying belt (104), the conveying belt (104) moves to drive the printing cloth to move to the rear side, the CPU controls the power (5) to start, the power (5) is powered on to make the heating wire (402) produce heat, then the drying fan (401) blows hot air, at this time, the CPU controls the first servo motor (310) and the second servo motor (311) to move the side link (304) and the front link (306) to forty-five degrees with the horizontal plane, at this time, the airflow blown by the micro fan (309) prevents the hot airflow blown by the upper drying fan (401) from escaping from the bottom end of the first baffle (301) or the bottom end of the baffle (303), so as to maintain the return flow efficiency of the hot airflow, when the green environmental protection printing equipment completes the drying work, the CPU controls the first servo motor (310) and the second servo motor (311) to move the side link (304) and the front link (306) to one hundred and thirty-five degrees, at this time, the CPU drives the pressure pump (602) to inject the cooling water stored in the water box (601) into the cooling box (203), the curved pipe (313) in the cooling box (203) is cooled, at this time, the cooling airflow blown by the micro fan (309) effectively and quickly cools the upper drying fan (401) and the heating wire (402), so as to improve the cooling capacity of the green environmental protection printing equipment.
