A special color ink dispensing valve structure and its measuring device

Abstract

The invention discloses a spot color ink distribution valve and spot color distributed ink taking and measuring equipment which is used for automatically measuring a viscous liquid. The valve structure comprises a valve body, a large valve rod, a small valve rod, a large liquid outlet nozzle, a small liquid outlet nozzle and two pressure mechanisms, the measuring equipment is equipped with a liquid pump, a reducing valve, a liquid feed pipe and a measuring and collecting device on the basis of the valve structure, and the liquid pump, the reducing valve and the liquid feed pipe are controlled by a computer. The valve structure is characterized in that the pressure mechanisms adopt spring stretching and retracting structures, and a cylinder controlled by the computer is arranged, so that the valve rods can slowly act, and excessive and too fast flow is avoided; and a high-flow liquid and a low-flow liquid can be separated by the large liquid outlet nozzle and the small liquid outlet nozzle, and coarse and fine control can be realized. According to the spot color ink distribution valve and the spot color distributed ink taking and measuring equipment, automatic weighing can be realized, manual operation is replaced, the accuracy and the efficiency are high, and the spot color distributed ink taking and measuring equipment is suitable for taking and measuring liquids such as oil, ink, detergent, medicament and the like with higher viscosities.

Description

technical field [0001] The invention belongs to the field of printing ink distribution, and in particular relates to a spot color ink distribution valve structure and a measuring device thereof. Background technique [0002] Some liquids that are more viscous than water, such as oil, detergent, ink, medicine, etc., are easy to cause equipment blockage due to their viscosity and poor fluidity, and it is not easy to control the flow rate, so in the prior art It is still mainly drawn by hand, and it is rarely dripped with a dropper. When drawing manually, it is first taken out with tools and then weighed. This method not only requires direct manual operation, resulting in high labor intensity, but also causes sticking, dripping, and dirty equipment or tools. It has the problems of low measuring accuracy and low measuring efficiency. Take the printing industry to do ink experiments or take ink. At present, the method of manually taking ink is often used at home and abroad to t...

AI Technical Summary

Problems solved by technology

Sometimes the more the manual is mixed, the more wrong it is, and even the ink that is mixed is directly abolished

This method of taking ink requires direct human labor, and it is difficult to take high-viscosity ink, it is not energy-saving, and it is not conducive to clean production

[0003] At present, there is another common method is to put a certain volume of liquid into the liquid taker, and open the lower opening of the container to slowly flow out the liquid in the cavity when using it. This method can only take a fixed volume of liquid, and it cannot be measured in the middle stage.

[0004] Existing general-purpose on-off valves, because they are not designed for high-viscosity liquids, generally have a long outflow channel. For inks with properties such as oxidized conjunctiva, long-term on-off valves that do not work will cause blockage, resulting in outflow channels. The change of the area will affect the stability of the flow

At the same time, the long outflow channel is not easy to clean
