Solenoid valve type digital printing sprayer

Abstract

The invention discloses a solenoid valve type digital printing sprayer. The solenoid valve type digital printing sprayer comprises a conductive plate, a solenoid coil, a coil rack, a solenoid valve body, a pressure pad, a base, a spray pipe, a valve body, a movable column, a spring, a dye spraying channel body, a pressing block and an adjusting gasket, wherein the dye spraying channel body is sleeved with the conductive plate, the outer side of the conductive plate is matched with the solenoid valve body, the coil rack is arranged in the solenoid valve body, the solenoid coil is arranged on the outer side of the coil rack, and the inside of the coil rack is matched with the dye spraying channel body. The movable column is arranged in the coil rack, the outer side of the movable column is sleeved with the spring, and the end of the spring is matched with the right end of the dye spraying channel body; the pressure pad is embedded into the right end of the movable column, the right end of the pressure pad makes contact with the spray pipe, the outer portion of the spray pipe is matched with the valve body, the left end of the valve body is matched with the solenoid valve body, and the base is arranged at the right end of the valve body. The ink jetting flow rate is conveniently adjusted through the multi-layer adjusting gasket, and disassembly is convenient; the base with a screwthread is applied so that convenience is brought to maintenance; the service life of the sprayer is long, easily damaged parts are easy to replace, and the maintenance cost is low.

Description

【Technical field】 [0001] The invention relates to the technical field of digital jet printing, in particular to the technical field of solenoid valve type digital printing nozzles. 【Background technique】 [0002] At present, the digital jet printing industry at home and abroad uses electromagnetic valve type nozzles to control the opening and closing time of inkjet. Different types of nozzles are used in different places. The inkjet volume of each type of nozzle is roughly the same. After the test, inkjet should be kept under the same pressure. The amount is consistent. The ink ejection volume is controlled by the pressure regulation of the ink. After one nozzle is turned on, the ink ejection volume remains constant under the same pressure, so as to achieve uniform ink ejection. The clogging of the nozzle leads to no ink ejection, and the carpet surface shows whiteness. When impurities break the gasket, the nozzle is not closed tightly and the ink leaks, and the carpet sur...

Problems solved by technology

A printing machine with a width of 4 meters and a width of 25DPI needs to replace 2048 nozzles at one time. The nozzles are expensive, and one replacement will increase the production cost. In order to solve the above problems, we decided to develop and design a printing nozzle with a reasonable and simple design and a long service life.
