Detailed Description
The following provides a more detailed description of the present invention with reference to the drawings and specific examples.
This kind of ink jet numbering machine printing ink detecting system, including the printing ink box, install the installation base 7 at the printing ink box opening part, set up in the constant voltage groove 3 in the installation base 7 outside and set up at the 1 inboard viscosity detection pipe 5 of installation base, printing ink in the printing ink box is carried to constant voltage groove 3 back through the pipeline, through 5 backward flows to the printing ink box of viscosity detection pipe.
And a sealing ring 2 is also arranged at the joint of the constant pressure tank cover 1 and the opening at the upper part of the constant pressure tank 3.
An inclined plane is transversely arranged in the body of the constant-pressure groove 1, a second through hole connected with a second throttling pipe 6 is arranged at the lower part of the inclined plane, and a first through hole connected with a first throttling pipe 4 is arranged at the higher part of the inclined plane; still be equipped with a baffle 8 on the inclined plane perpendicularly, cut apart into mixing area and overflow district with this internal chamber of constant voltage groove, overflow district bottom is equipped with the discharge orifice 9 with the ink tank inner chamber intercommunication, first through-hole and second through-hole all set up in mixing area. The first through-hole, to which the first throttle pipe 4 is connected, may maintain a constant pressure by a constant cross-section. The second through hole connected with the second throttle pipe 6 can realize the shunting of the printing ink and the constant printing ink working pressure.
The mixing area space is larger than the overflow area space, and the height of the top end of the baffle 8 is not more than the opening at the upper part of the constant-pressure tank body.
The viscosity detection tube 5 is opened at the upper part and communicated with the first throttling tube 6.
Three probe needles 10, namely a high probe needle, a middle probe needle and a ground probe needle, are arranged in the viscosity detection tube 5 according to the distance from the bottom of the viscosity detection tube.
The bottom of the viscosity detection tube 5 is designed to be a sharp corner for accommodating ink deposition. The bottom of the viscosity detection tube is designed to be a sharp corner. A plurality of colored dye-based inks are used on the ink-jet printer, and the dye-based inks are characterized by being easy to accumulate ink and generate blockage for a long time. Therefore, the bottom of the viscosity detection tube is designed to be a sharp corner, so that the sediment of the ink is left at the bottom and is brought into an ink tank through a siphon tube, and the bottom of the ink tank is provided with a stirrer, so that the sediment is mixed into the ink and is reused.
The viscosity detection tube 5 is also provided with a siphon tube 11, one end of the siphon tube 11 is communicated with the bottom of the viscosity detection tube 5, and the other end of the siphon tube is communicated with the ink tank.
An inner flow passage used for communicating the constant-pressure groove with the viscosity detection tube is arranged in the mounting base 7.
First, ink is pressed into the pipe of the second orifice pipe installed in the bottom of the constant pressure tank 3, and after the ink is exchanged in the constant pressure tank 3, the ink flows into the pipe of the second orifice pipe through the second through hole, and finally enters the viscosity detecting pipe 5.
The viscosity detection of the ink is completed inside the ink viscosity detecting tube 5. The ink level rises from the bottom of the ink viscosity detecting tube 5. At this moment, three probe needles with different lengths are arranged in the ink detection tube 5 for detection, firstly, the ink liquid level firstly touches the lowest probe needle, then the liquid level continuously rises until reaching the middle probe needle, and at this moment, the code spraying machine system calculates the rising time of the liquid level and calculates the probe from the accumulated time to the highest position of the liquid level. The cumulative rise time is then converted to the corresponding ink viscosity value.
At this time, the liquid level of the ink in the ink viscosity detection tube 5 continues to rise, and when the liquid level rises to a level higher than the height of the siphon tube, the ink in the ink viscosity detection tube 5 flows into the ink tank from the siphon tube. And the ink is in the viscosity detection pipe in a circulating way, and the liquid level rises from the low level to the high level again, so that the circulating detection of the ink viscosity is realized.
If the ink viscosity is high, the appropriate solvent dosage is drawn from the solvent bottle and replenished into the ink tank. Conversely, if the ink viscosity is low, the appropriate amount of ink will be drawn from the ink bottle and replenished into the ink tank. Thereby maintaining a proper value of the viscosity of the ink and ensuring the quality of the ink.
Except that a probe pin is provided in the ink viscosity detecting tube 5. A set of needles may also be provided in the ink tank. When the ink rises to the two needles at the lowest position, the signals are communicated, and when the ink is replenished to the needle at the highest position, the highest position of the ink in the ink tank is limited, and the ink is not replenished.
The ink detection system is disassembled now as long as the constant pressure tank is disassembled. In the traditional ink detection system of the ink-jet printer, the mixing cylinder and a plurality of external pipelines need to be disassembled, and the easy maintenance of the ink system is improved through the improvement of the design.
The design scheme of the invention greatly reduces hoses and joints for conveying ink, which is proved by design and practice of the inventor. Because there is the elasticity problem of assembly joint in the production, there is the hidden danger that the printing ink revealed. At present, pipelines are greatly reduced, and joints are also reduced by half, so that the fault rate of the ink detection system is greatly reduced.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
