Abstract
The utility model discloses a constant pressure device of an ink supply system, which comprises a positive pressure air pump, a negative pressure air pump, a positive pressure solenoid valve, a negative pressure solenoid valve, a controller, a negative pressure tank and a spray head; the normally open end and the normally closed end of the positive pressure electromagnetic valve are respectively connected with the positive pressure air pump and the negative pressure tank; the output end of the positive pressure electromagnetic valve is connected with the spray head, and the normally closed end of the negative pressure electromagnetic valve is connected with the negative pressure air pump; the output end of the positive pressure electromagnetic valve is connected with the negative pressure tank, and the controller is respectively electrically connected with the positive pressure electromagnetic valve, the negative pressure electromagnetic valve and the negative pressure tank. The negative pressure tank is also provided with an exhaust electromagnetic valve. Through the utility model discloses the negative pressure that can control the shower nozzle is constant pressure, and the error is little to realize high-efficient high-quality spout seal, simultaneously, to spouting the shower nozzle that the seal quality descends to some extent, wash the shower nozzle through malleation ink, not only protected the shower nozzle, guaranteed the quality of spouting the seal simultaneously again.
Description
Technical Field
The utility model relates to an ink supply system technical field specifically is ink supply system's constant voltage equipment.
Background
The traditional nozzle needs negative pressure to absorb ink during jet printing, so that the ink does not flow out of the nozzle. If the input air pressure fluctuates, the converted negative pressure fluctuates up and down, so that the content of jet printing can be fuzzy and even broken, and can not be jetted out in serious cases, even ink leaks from the jet head, thereby greatly reducing the working efficiency and increasing the labor cost.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an ink feeding system's constant voltage equipment to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a constant pressure device of an ink supply system is characterized in that: the constant pressure device comprises a positive pressure air pump, a negative pressure air pump, a positive pressure electromagnetic valve, a negative pressure electromagnetic valve, a controller, a negative pressure tank and a spray head; the normally open end and the normally closed end of the positive pressure electromagnetic valve are respectively connected with the positive pressure air pump and the negative pressure tank; the output end of the positive pressure electromagnetic valve is connected with the spray head, and the normally closed end of the negative pressure electromagnetic valve is connected with the negative pressure air pump; the output end of the positive pressure electromagnetic valve is connected with the negative pressure tank, and the controller is respectively electrically connected with the positive pressure electromagnetic valve, the negative pressure electromagnetic valve and the negative pressure tank.
Preferably, the negative pressure tank is further provided with an exhaust solenoid valve.
Compared with the prior art, the beneficial effects of the utility model are that:
through the utility model discloses the negative pressure that can control the shower nozzle is constant pressure, and the error is little to realize high-efficient high-quality spout seal, simultaneously, to spouting the shower nozzle that the seal quality descends to some extent, wash the shower nozzle through malleation ink, not only protected the shower nozzle, guaranteed the quality of spouting the seal simultaneously again.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1 positive pressure air pump, 2 negative pressure air pumps, 3 positive pressure solenoid valves, 4 negative pressure solenoid valves, 5 exhaust solenoid valves, 6 controllers, 7 negative pressure tanks and 8 spray heads.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below. The embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative work, all belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the negative pressure air pump 2 works and the negative pressure electromagnetic valve 4 is opened, negative pressure is generated in the negative pressure tank 7 at the moment, a negative pressure sensor is arranged in the controller 6 to control and set the size of the negative pressure in the negative pressure tank 7, the negative pressure in the negative pressure tank 7 is transmitted into the spray head 8 through the long-distance connector of the positive pressure electromagnetic valve, so that stable constant negative pressure is generated, ink in the spray head can be dragged by the negative pressure so as not to flow down, and stable spray printing is realized.
When the jet printing quality of the jet head is reduced, the jet head can be cleaned by positive pressure ink.
The production process of malleation, 1 work of positive pressure air pump 3 work of solenoid valve simultaneously, and the malleation is direct to the shower nozzle through solenoid valve 3, has just so realized the malleation process, washs shower nozzle 8 through malleation ink.
The negative pressure tank is also provided with an exhaust electromagnetic valve 5 which can exhaust the gas in the negative pressure tank 7.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
