Description

Technical Field

[0001] The invention relates to the technical field of plate UV printing, in particular to a plate UV printing device. Background Art

[0002] Ceramic inkjet printing technology originated in the 1990s and was initially used for paper printing. With the development of technology, ceramic inkjet printing technology has gradually been applied to the production of ceramic products. At present, ceramic inkjet printing technology has become an important production process in the ceramic industry and is widely used in the fields of construction, home furnishing and industry. The Chinese patent application with application number 202311418587.3 discloses "a plate UV digital printing device and a plate digital printing method, including a conveyor belt assembly, a plurality of through holes are provided on the belt surface of the conveyor belt assembly, and baffles are equidistantly arranged on the belt surface of the conveyor belt assembly; a feeding assembly is arranged at one end of the conveyor belt assembly, and is used to place the plates between the baffles one by one; a screw feed assembly spans the conveyor belt assembly, and a printing module is connected to the screw feed assembly, and the screw feed assembly drives the printing module laterally to print the plate; an air box is arranged on the lower surface of the upper belt body of the conveyor belt assembly, and the air box is vertically aligned with the printing module, and the air box is connected to an air pump, and the air pump discharges the gas in the air box to form a negative pressure; the present invention uses the conveyor belt assembly to convey the plates one by one in a directional manner, and cooperates with the screw feed assembly to laterally adjust the position of the printing module, so as to realize continuous printing and processing of the plates, which is efficient and suitable for batch plate printing and processing".

[0003] This technical solution only solves the problem that the UV printing equipment fixes the material through a vacuum adsorption platform, and then drives the printing component to implement covering printing on the material surface through a flat mobile device. However, large quantities of plates need to be printed with a unified pattern, and the materials need to be picked up and placed one by one on the platform surface, resulting in low printing efficiency. However, when printing large-size plates such as crystalline silicon plates, the plates are easily attached to dust in the environment during operation, which can easily lead to poor adhesion of the printed materials on the plates. When large particles of dust adhere to the plates, the surface of the plates will be uneven, resulting in poor printing effects. In addition, the ink used in UV printing has the property that its viscosity changes with temperature. The viscosity of the UV ink can be changed by changing the temperature of the UV ink, but during the printing process, the temperature is often not adjusted in time, resulting in uneven viscosity of the UV ink, which can easily affect the printing effect.

There are two first bevel gears 906, which are respectively fixedly sleeved on one end of the two fixed tubes 903 close to the inner center of the ink mixing cylinder 901 by bolts; ink is loaded through the ink mixing cylinder 901, and the first bevel gear 906 is fixedly installed through the fixed tube 903;

[0038] The UV ink mixing mechanism 9 includes a rotating frame 907, a rotating groove 908, a horizontal shaft 909, a second bevel gear 911 and a transmission belt 912.

[0039] Working principle: When the present invention is in use, the movable box 701 moves with the printing device 4. When the movable box 701 moves, the transmission gear 705 inside it moves with the movable box 701. When the transmission gear 705 moves, the transmission gear 705 is meshed with the tooth plate 702, so that the transmission gear 705 rotates. At this time, the rotating shaft 704 rotates with the transmission gear 705, and drives the connecting plate 706 to rotate at the same time through the rotating shaft 704. When the connecting plate 706 rotates, it drives the lifting column 707 inserted inside it to rotate with the rotating shaft 704 as the axis at the same time, and the cleaning brush 709 at the bottom end of the lifting column 707 rotates with the lifting column 707 at the same time. The cleaning brush 709 that rotates with the rotating shaft 704 as the axis is used to clean the plate that has not been printed. When the cleaning brush 709 contacts the plate, the elastic force of the spring 708 makes the cleaning brush 709 close to the surface of the plate, thereby improving the cleaning effect of the cleaning brush 709 on the surface of the plate.

[0040] When a rotating shaft 704 located inside the movable box 701 rotates, the cam group 806 at its top is driven to rotate at the same time. When the cam group 806 rotates, the piston 805 is driven to reciprocate in the air box 801 through the reciprocating rod 808. When the piston 805 moves in the direction of the cam group 806, the inside of the air box 801 is in a state of exhausting air. At this time, the air inlet check valve in the air inlet pipe 802 is opened, and the air outlet check valve in the air outlet pipe 803 is closed, so that the air outside the movable box 701 is exhausted. The air enters the air box 801 through the air inlet pipe 802. When the piston 805 moves away from the cam assembly 806, the inside of the air box 801 is in an exhaust state. At this time, the air inlet check valve in the air inlet pipe 802 is closed, and the air outlet check valve in the air outlet pipe 803 is opened, so that the air in the air box 801 is discharged to the dust blowing box 804 through the air outlet pipe 803, and then the air is blown to the surface of the plate through the dust blowing box 804. The air blown out by the dust blowing box 804 blows away the dust on the surface of the plate;

[0041] When the cam group 806 rotates, the linkage shaft 809 is driven to rotate through the connecting shaft 807. When the linkage shaft 809 rotates, the transmission shaft 905 is driven to rotate through the transmission belt 912. When the transmission shaft 905 rotates, the rotating frame 907 is driven to rotate inside the ink mixing cylinder 901. The ink attached to the inner wall of the ink mixing cylinder 901 is scraped off by the rotating rotating frame 907 to prevent the ink from adhering to the inner wall of the ink mixing cylinder 901, so that all the ink attached to the inner wall of the ink mixing cylinder 901 participates in printing. Since the first bevel gear 906 is fixed, when the rotating frame 907 rotates, When the ink mixing cylinder 901 is in motion, the second bevel gear 911 is meshed with the first bevel gear 906 to make the horizontal shaft 909 rotate, and the rotating plate 910 is driven to rotate in the rotating groove 908 through the horizontal shaft 909. At this time, the rotating frame 907 rotates while making the rotating plate 910 rotate. The rotating frame 907 rotates and stirs the ink inside the ink mixing cylinder 901 while scraping the ink on the inner wall of the ink mixing cylinder 901, and the rotating rotating plate 910 is used to evenly mix the upper and lower layers of the ink inside the ink mixing cylinder 901, so that the ink is mixed and the temperature is uniform, thereby improving the printing effect.
