[0002] Ink is an important material for printing, and it shows patterns and words on a printing substrate through printing or spraying. Ink includes main components and auxiliary components, which are evenly mixed and repeatedly rolled into a viscous colloidal fluid. It is composed of a binder (resin), pigments, fillers, additives, solvents, etc. It is used for various printings such as books, packaging and decoration, architectural decoration, and electronic circuit boards. With the increasing social demand, the variety and output of ink have also expanded and increased accordingly.

[0003] Currently, ink is used in many fields. For example, in an inkjet printer, inkjetting ink can form required shapes, patterns, colors, etc. In actual use, ink usually needs to be mixed with a diluent before use, and at the same time, the amount of diluent required for different inks also varies. Therefore, it is necessary to detect the viscosity of ink (usually referring to the ink mixed with the diluent). However, the price of the viscosity detection equipment sold on the market is usually high, resulting in a high use cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide an ink viscosity detection mechanism, aiming to solve the problem of high cost.

[0005] To solve the above technical problems, the utility model provides an ink viscosity detection mechanism, which includes a detection cavity. A receiving cavity is formed in the middle of the detection cavity. The bottom of the receiving cavity is in a trumpet shape with a larger upper part and a smaller lower part.

[0017] Compared with the prior art, the utility model provides an ink viscosity detection mechanism. When detecting the ink viscosity, first, the ink is introduced into the accommodation cavity of the detection cavity. When the ink volume reaches the specified amount, the ink input is stopped, and then the timing starts. After that, under the action of its own gravity, the ink drips downward through the ink dripping port to the outside until it finally drips out completely. The time from the start to the end of dripping is recorded, and then the viscosity of the ink is deduced. The deduction method needs to be designed according to one's own situation and is not limited here too much. Since the viscosity calculation of the ink only needs to record the time required from when the ink reaches the required amount to the end of dripping, the detection cost is relatively low.

An ink dripping port 3 is provided at the bottom of the detection cavity 1, and the ink dripping port 3 communicates with the bottom of the accommodation cavity 2.

[0031] A sealing cover 4 for sealing the detection cavity 1 is provided at the top of the detection cavity 1. A ink conveying pipe 5 is connected to the side of the top of the detection cavity 1, and the ink conveying pipe 5 is used to input ink into the accommodation cavity 2. An air inlet communicating with the outside is provided at the top of the detection cavity 1.

[0032] An air inlet pipe 6 is vertically provided on the side of the detection cavity 1. The bottom of the air inlet pipe 6 communicates with the outside, and the top communicates with the air inlet.

[0033] An ink blocking cover 7 is provided on the inner wall of the detection cavity 1. The ink blocking cover 7 is in the shape of a cover with an opening downward, and the air inlet communicates with the inner cavity of the ink blocking cover 7.

[0034] Three connection blocks 8 are evenly provided at the top of the detection cavity 1, and the sealing cover 4 is fixedly connected to the three connection blocks 8.

[0035] The three connecting blocks 8 are respectively a first connecting portion 8a, a second connecting portion 8b and a third connecting portion 8c. An L-shaped fastening member 12 is arranged on the side of the first connecting portion 8a. A cylindrical rotating hole 13 is vertically formed at the top of the second connecting portion 8b. A relief opening 14 is vertically formed on the outer side of the rotating hole 13. A cylindrical rotating opening 15 is formed at the bottom of the relief opening 14. The projections of the rotating hole 13 and the relief opening 14 in the vertical direction are both located within the projection of the rotating opening 15 in the vertical direction;

[0036] A linkage rod 16 is arranged at the bottom of the sealing cover 4. An anti-detachment portion 17 is arranged on the inner side of the bottom end of the linkage rod 16. The anti-detachment portion 17 can movably pass through the relief opening 14. The relief opening 14 and the anti-detachment portion 17 are located on both sides of the linkage rod 16. The outer wall of the linkage rod 16 is attached to the inner wall of the rotating hole 13. The top of the anti-detachment portion 17 abuts against the top of the rotating opening 15. The bottom of the sealing cover 4 is attached to the top of the detection cavity 1. The side and the top of the sealing cover 4 are attached to the inner wall of the fastening member 12;

[0037] A positioning bolt 18 is movably arranged through the sealing cover 4. The positioning bolt 18 is in threaded connection with the third connecting portion 8c. An annular sealing layer is arranged at the top of the detection cavity 1.

[0038] A top liquid level sensor 19 and a bottom liquid level sensor 20 (both are commercially available liquid level sensors) are arranged on the sealing cover 4. The top liquid level sensor 19 is located within the accommodation cavity 2. The bottom liquid level sensor 20 is located at the bottom of the accommodation cavity 2.

[0039] When detecting the viscosity of the ink, first, the ink is introduced into the accommodation cavity 2 of the detection cavity 1. When the ink volume reaches the specified amount, the input of the ink is stopped, and the timing starts at this time; then, under the action of its own gravity, the ink drips downward through the ink dripping port 3 to the outside until it finally drips out completely. Record the time from the start to the end of dripping, so as to calculate the viscosity of the ink. The calculation method needs to be designed by yourself according to your own situation and will not be restricted too much here. Since the viscosity calculation of the ink only needs to record the time required for the ink from reaching the required amount to dripping out completely at this time, the detection cost is relatively low.

[0040] In actual use, the mechanism of the present application is suitable for the mixing tank of ink and diluent; first, a certain amount of ink and diluent are injected into the mixing tank and mixed; after the mixing is completed, the mixed ink in the mixing tank is sent into the containing chamber 2 through the ink tube 5 by a pump, and when the ink in the containing chamber 2 acts on the top liquid level sensor 19 (which is lower than the air inlet), the top liquid level sensor 19 sends a signal to the controller, and the controller controls the pump to stop, and then the ink drips back into the mixing tank at the ink drop port 3. When the last ink drips, the bottom liquid level sensor 20 sends a signal to the controller, and the controller can obtain the entire ink dripping time and calculate the ink concentration in real time; then, according to the vertical obtained by calculation, no action is taken, or a corresponding amount of ink is injected into the mixing tank, or a corresponding amount of diluent is injected into the mixing tank, and finally the ink of the required concentration is obtained after uniform mixing. The bottom of the ink drop port 3 is always connected to the mixing tank, and all the detection ink is discharged back into the mixing tank.

[0041] When the ink is pumped into the containing chamber 2, the ink shield 7 can block the ink and effectively prevent the ink from entering the air inlet pipe 6; at the same time, when the ink is dripping, the air in the mixing tank enters the containing chamber 2 through the air inlet pipe 6 and the air inlet port, so that the internal ink can drip downward normally. Secondly, it can also prevent external air from entering the mixing tank and the detection chamber 1, thereby ensuring the cleanliness of the ink.

[0042] When installing the sealing cover 4, firstly, the sealing cover 4 is rotated to a direction away from the detection cavity 1, and the anti-slipping part 17 is located above the clearance opening 14 at this time; then the sealing cover 4 is lowered and the anti-slipping part 17 is entered into the clearance opening 14, and the linkage rod 16 enters the rotation hole 13, until the sealing cover 4 is fitted into the detection cavity 1, and then the sealing cover 4 is rotated horizontally, and the side of the sealing cover 4 is abutted against the inner wall of the fastening member 12, and the anti-slipping part 17 is also rotated to a state of being misaligned with the clearance opening 14; finally, the sealing cover 4 is fixed by the positioning bolt 18 It is fixedly connected to the third connecting portion 8c. At this time, the sealing cover 4 is fixedly connected to the detection chamber 1 in the horizontal direction and in the vertical direction. At the same time, there is a flexible sealing layer between the sealing cover 4 and the detection chamber 1, which can ensure the sealing and stability of the connection between the sealing cover 4 and the detection chamber 1 and prevent external impurities from entering; secondly, only one positioning bolt 18 is needed in the entire connection process, and the operation is convenient. In the vertical direction, the anti-slip portion 17, the buckle 12 and the positioning bolt 18 can limit the sealing cover 4, thereby ensuring the sealing.

[0045] The bottom of the sealing cover 4 is provided with an annular sealing portion 10, and the top of the detection cavity 1 is provided with a sealing groove 11 that cooperates with the sealing portion 10.

[0046] When connecting the sealing cover 4, the sealing cover 4 is sleeved on the top of the detection cavity 1 from top to bottom. Finally, the three connecting bolts 9 pass through the sealing cover 4 and are threadedly connected with the connecting blocks 8. Secondly, at this time, the sealing portion 10 is engaged in the sealing groove 11, which can further ensure the sealing effect.
