Description
[technical field]
The utility model relates to the ink tank that a kind of spray printing equipment uses, and specifically a kind of ink tank that keeps CL belongs to the spray printing apparatus field.
[background technology]
When spray printing equipment was worked, in the time of consumption of ink, the ink level of ink tank descended, and the variation of ink pressure can cause ink ejection amount to change, and influences the spray printing effect, make the picture and text shade differ, inhomogeneous.In order to prevent that ink level from descending, the maintenance liquid level is constant and ink pressure stable, must replenish ink.Traditional method is to adopt sensor closed-loop system control drawing liquid pump, and sensor monitors liquid level and descends and promptly send signal and make drawing liquid pump start, and pumps into the interpolation ink automatically, when sensor monitors liquid level when reaching preset height, then controls drawing liquid pump and quits work.This sensor and drawing liquid pump control structure complexity, the manufacturing cost height, the pressure stability of ink had both depended on the sensitivity of sensor, depended on the working stability situation of drawing liquid pump again.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is the defective that overcomes prior art, forms pressure dynamic equilibrium to keep the constant ink tank of ink level in the ink tank between hydraulic pressure, air pressure and the atmospheric pressure that provides a kind of rational in infrastructure, low cost of manufacture, utilization to inject ink.For this reason, the utility model adopts following technical scheme:
The ink tank that keeps CL comprises the ink tank that has the ink outlet, it is characterized in that the ink inlet position of described ink tank is provided with connector; Described connector is provided with two through holes and runs through the lateral aperture of two through holes, be provided with spool in the lateral aperture, one through hole is connected with long and short air inlet pipe in two ends up and down, another through hole lower end connects the creeping pipe, described short air inlet pipe and creeping pipe stretch in the ink tank, and the ink tank top is provided with inlet channel.During installation, the shutoff ink exports, and connector is taken off with ink bottle be connected, and makes the progress tracheae stretch in the ink bottle, spool blocks two through holes, thereby when ink bottle was connected with ink tank, connector played the effect of bottle cap, and ink can not flow out under inclination, the rollover states, when work good in connector and ink inlet position, short air inlet pipe and creeping pipe are arranged in ink tank, open spool, and ink bottle is communicated with by long and short air inlet pipe and creeping pipe with ink tank.If short air inlet pipe is arranged in the ink level top of ink tank, ink in the ink bottle is under the effect of gravity (hydraulic pressure) and/or air pressure, flow into ink tank downwards from the creeping pipe, along with air constantly enters into ink bottle from weak point, progress tracheae, ink continues dirty; Will stop air to enter in the short air inlet pipe ink bottle when the liquid level in the ink tank reaches the lower end of short air inlet pipe is not communicated with atmosphere, when creeping pipe lower end external and internal pressure equates, ink in the ink bottle can stop to flow into ink tank, after the work of spray printing equipment further consumes ink in the ink tank and makes liquid level descend, air can constantly enter into the ink that ink bottle makes ink bottle by weak point, progress tracheae again and flow into ink tank until pressure balance, and this physical state is in dynamic equilibrium.Therefore, during the work of spray printing equipment, liquid level can keep constant altitude in the ink tank, and the ink in ink bottle uses until exhausted, spray printing picture and text depth high conformity, quality height.Connector is set ink bottle is separated at any time with ink tank, connector and ink bottle, irritate China ink, change work such as China ink, be convenient to again ink bottle is connected on the ink tank, rational in infrastructure, low cost of manufacture.
For the improving and replenishing of technique scheme, can increase following technical characterictic or its combination:
Described connector top has the ink bottle link slot, is provided with sealing ring in the groove, pegs graft in connector bottom and ink inlet position.The ink bottle that connector is installed tilts, when being inverted because sealing ring and spool close and make ink can not leak outside or air enters, the connector that will have an ink bottle is with after ink tank is connected, the integrated device that ink bottle is communicated with ink tank formation.
Described short air inlet pipe is consistent with creeping pipe lower open end height.Prevent that the ink in the ink tank from pouring in down a chimney in the short air inlet pipe, block short air inlet pipe after drying up.
Described spool is shaft-like, and corresponding long and short air inlet pipe, creeping pipe place have air admission hole and creeping hole respectively, and spool one end exposes connector and is provided with handle.The external diameter of spool and the lateral aperture of connector should closely cooperate, and can make the spool activity, make it sealing again.When opening spool, rotate or draw by handle and push away spool, make air admission hole and creeping hole be communicated with air inlet pipe, creeping pipe, formation air flue and ink via when closing spool, rotate or draw and push away spool, spool outer wall shutoff air flue and ink via.
Be provided with small sealing ring between described spool and the connector, spool exposes the connector place and has circlip groove and be provided with back-up ring.Form secondary seal, prevent that ink from leaking outside or air enters, in fact, sealing ring remedies spool and cooperates the problem that occurs because of workpiece accuracy with connector, has further strengthened the sealing property of spool and connecting rod.
Described spool is provided with the handle installing hole.Handle and spool are pegged graft or be spirally connected, and be convenient and swift.
Described ink bottle link slot inwall is provided with screw thread.Be convenient to fast firmly be connected with ink bottle.
Form the principle of pressure dynamic equilibrium between hydraulic pressure, air pressure and the atmospheric pressure of the utility model utilization injection ink, need not complicated electronic component and drawing liquid pump and can control the interior liquid level of ink tank delicately, make it remain on constant altitude, the length of adjusting or change short air inlet pipe and creeping pipe can change liquid level, simple, rational in infrastructure, low cost of manufacture helps to stablize the spray printing quality.
