Description

Technical Field

[0001] The utility model relates to the technical field of digital printing machines, in particular to an anti-blocking and moisturizing structure for an inkjet head of a digital inkjet printing machine. Background Art

[0002] Digital inkjet printer is a "non-contact with the object" inkjet printing type high-tech digital printing equipment, so it is not restricted by any materials and can perform color photo-level printing on the surface of a variety of materials.

[0003] Digital inkjet printers use high-precision print heads and high-quality consumables to achieve high-precision, high-resolution printing effects. The output images, text, lines, etc. are clear, delicate, colorful and realistic, and can meet customers' personalized printing needs. Compared with traditional printing presses, digital printing presses do not require plate making, have low material consumption and low production costs. At the same time, digital printing presses can also achieve small-batch, personalized printing, avoiding the problems of complex plate making and large batches of traditional printing mechanisms, and are more convenient and flexible.

[0004] The digital inkjet printer in the prior art sprays different colors of ink mixed and dripped onto paper for printing through an inkjet head that is narrow at the bottom and wide at the top. The inkjet head that is narrow at the bottom and wide at the top can form a negative pressure inside the inkjet head, so that the ink will not drip onto the paper at will. However, the ink of this inkjet head will remain in the inkjet head after use. When no one uses it for a long time, the ink will dry in the inkjet head due to water loss, affecting subsequent inkjet printing and easily causing damage to the printer. Utility Model Content

[0036] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figure 1~Figure 4 As shown, this embodiment proposes an anti-blocking and moisturizing structure for the inkjet head of a digital inkjet printer, including a printer body 1, an inkjet head 2, an inkjet head adjustment mechanism, a moisturizing box 3, a sealing mechanism and a water adding component. The inkjet head 2 is slidably connected to the printer body 1, the inkjet head adjustment mechanism is installed on the printer body 1, the moisturizing box 3 is slidably connected in the printer body 1, the sealing mechanism is installed in the moisturizing box 3, and the water adding component is installed on the outer wall of the printer body 1. When the printer is used up, the sealing mechanism is started to move the moisturizing box 3 to the bottom of the inkjet head adjustment mechanism, and the inkjet head adjustment mechanism presses the inkjet head 2 into the moisturizing box 3, and the water adding component adds water to the moisturizing box 3 to seal and moisturize the inkjet head 2 to achieve the effect of anti-blocking and moisturizing, and the inkjet head 2 can be cleaned at the same time.

[0038] Among them, the inkjet head adjustment mechanism includes a mounting groove and an electric cylinder 4. There are two mounting grooves, and the two mounting grooves are opened at the top of the printing machine body 1. There are two electric cylinders 4, and the two electric cylinders 4 are fixedly connected in the two mounting grooves. The output end of the electric cylinder 4 is fixedly connected to the inkjet head 2. The inkjet head adjustment mechanism pushes the inkjet head 2 up and down through the electric cylinder 4.

[0039] Secondly, the sealing mechanism includes a slide groove, a sealing frame 5, a spring telescopic rod 6 and an electric cylinder 2 7. The slide groove is opened on the moisturizing box 3, the sealing frame 5 is slidably connected in the slide groove, a plurality of spring telescopic rods 6 are provided, and a plurality of spring telescopic rods 6 are fixedly connected in the slide groove, and a plurality of spring telescopic rods 6 are fixedly connected between the sealing frame 5 and the spring telescopic rod 6. There are two electric cylinders 2 7, and the two electric cylinders 2 7 are fixedly connected to the printing machine body 1. The output end of the electric cylinder 2 7 is fixedly connected to the moisturizing box 3. When working, the electric cylinder 2 7 is started to drive the moisturizing box 3 to move to the bottom of the inkjet head 2, and then the sealing frame 5 seals the moisturizing box 3 and the printing body, and water is added to make the inkjet head 2 immersed in water to keep the inkjet head 2 moist and sealed, and prevent the ink from drying in the inkjet head 2, which affects the printing effect and even causes damage to the equipment, which is conducive to the cleaning of the inkjet head 2.

[0040] Again, the water adding component includes a water tank 8, a water pump 9 and a water pipe 10. The water tank 8 is fixedly connected to the printer body 1. Two water pumps 9 are provided.
