A kind of spraying device, spraying system and spraying method

Abstract

The invention discloses a spraying device, a spraying system and a spraying method. The spraying device comprises a main body part, a first pressurized structure, a liquid supply pipeline and a second pressurized structure; a liquid accommodating chamber is formed in the main body part and used for accommodating spraying liquid, and one end of the main body part is provided with an liquid outlet communicated with the liquid accommodating chamber, so that spraying liquid in the liquid accommodating chamber can be output from the liquid outlet; the first pressurized structure is arranged on the side, opposite to the liquid outlet, of the main body part, and the first pressurized structure is connected with the main body part and used for providing first pressure to the liquid accommodating chamber of the main body part; the liquid supply pipeline and the first pressurized structure are arranged on the same side of the main body part, the direction in which the liquid supply pipeline outputs the spraying liquid is parallel to the direction in which the spraying device outputs the spraying liquid, and the liquid supply pipeline is used for providing the spraying liquid; the second pressurized structure is connected with the main body part and used for providing second pressure for the liquid accommodating chamber of the main body part. By this way, the pressure in the spraying device can be improved, and the yield of products is improved.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a spraying device, a spraying system and a spraying method. Background technique [0002] When the existing spraying equipment is filled with spraying liquid, due to the characteristics of the process and materials, the spraying liquid contacts the surface of the internal structure of the spraying equipment, resulting in viscous resistance. According to the characteristics of the fluid on the critical surface, the spraying equipment 100 will have a dripping situation during the spraying process, such as figure 1 shown. Due to the insufficient internal pressure of the spraying equipment 200, the spraying liquid remains in the nozzle position of the spraying equipment 200, such as figure 2 As shown, or due to atmospheric pressure, the spraying liquid at the nozzle position of the spraying equipment 300 is backflowed, so that the spraying liquid does not drop completely, as im...
