DETAILED DESCRIPTION

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0015] Example

[0016] To address the aforementioned technical problems, this embodiment provides an automatic control device for ink concentration in a printing machine, such as... Figure 1 As shown, the system includes an ink tank 10 and an ink concentration detection component 20 disposed on one side of the ink tank 10. A solvent replenishment component 30 is also connected to the ink tank 10. The ink concentration detection component 20 and the solvent replenishment component 30 are electrically connected to a control system 11. The control system 11 is communicatively connected to the ink concentration detection component 20. By providing the ink concentration detection component 20 on one side of the ink tank 10, the ink concentration value in the ink tank 10 can be monitored in real time. Furthermore, by providing the solvent replenishment component 30 to the ink tank 10, and by electrically connecting the ink concentration detection component 20 and the solvent replenishment component 30 to the control system 11, the control system 11 can feed back the ink concentration obtained by the ink concentration detection component 20 to the control system 11. The control system 11 then drives the solvent replenishment component 30 to release solvent into the ink tank 10, thereby automatically and in real time adjusting the ink concentration in the ink tank 10, improving the efficiency of the production line, and precisely controlling the ink concentration to the required range.

[0017] Specifically, the ink concentration detection component 20 includes a fixed frame 21 and a concentration detection barrel 22 slidably disposed on the fixed frame 21. A first driving component 23 is also disposed on the fixed frame 21, and the driving end of the first driving component 23 is connected to the concentration detection barrel 22. By slidably disposing the concentration detection barrel 22 on the fixed frame 21 and the first driving component 23 with its driving end connected to the concentration detection barrel 22 on the fixed frame 21, in some embodiments, the first driving component 23 can be a driving cylinder. When the first driving component 23 drives the concentration detection barrel 22 to slide to a height lower than the installation height of the ink barrel 10, the ink in the ink barrel 10 can flow into the concentration detection barrel 22. Then, the first driving component 23 drives the concentration detection barrel 22 to slide to an initial position higher than the installation height of the ink barrel 10, and the ink in the concentration detection barrel 22 can flow back to the ink barrel 10. The ink concentration time value is detected by the ink return speed, thereby adjusting the installation height of the concentration detection barrel 22 to match the inflow or outflow of ink.

[0018] In the above scheme, the ink concentration detection assembly 20 further comprises two liquid level sensing components 24 arranged on the outer side wall of the concentration detection barrel 22, and a calibration dropper 25 arranged at one end of the concentration detection barrel 22, and a first on-off valve 26 arranged on the calibration dropper 25. By arranging two liquid level sensing components 24 on the outer side wall of the concentration detection barrel 22, the liquid level sensing components 24 can be divided into an upper liquid level sensor and a lower liquid level sensor. When the ink in the ink barrel 10 flows into the concentration detection barrel 22 through the liquid level difference and fills to the upper calibration position, the upper liquid level sensor in the liquid level sensing component 24 is turned on and sends a signal to the control system 11, so that the control system 11 can stop the ink in the ink barrel 10 from flowing into the concentration detection barrel 22, and drive the first drive assembly 23 to drive the concentration detection barrel 22 back to the initial installation height above the ink barrel 10. Then, by arranging the calibration dropper 25 at one end of the concentration detection barrel 22 and the first on-off valve 26 on the calibration dropper 25, and then driving the first on-off valve 26 to open by the control system 11, the ink in the concentration detection barrel 22 can flow back to the ink barrel 10 through the calibration dropper 25. At this time, the control system 11 starts timing, and the ink in the concentration detection barrel 22 starts to flow back to the ink barrel 10. When the ink in the concentration detection barrel 22 continues to flow out and the liquid level drops to the lower calibration position, the lower liquid level sensor in the liquid level sensing component 24 is turned on and sends a signal to the control system 11, so that the control system 11 can stop timing, thereby measuring the current ink concentration time data in the ink barrel 10, and realizing the regulation of the ink storage in the concentration detection barrel 22 to ensure the accuracy of the calculated ink concentration value.

[0019] Further, a plurality of groups of feeding ports 12 are arranged on the outer side wall of the ink barrel 10, and a second on-off valve 13 is arranged on one of the feeding ports 12. By arranging a plurality of groups of feeding ports 12 on the ink barrel 10, when the ink in the concentration detection barrel 22 flows back to the ink barrel 10 through the liquid level difference, the ink can be transported through the communication between the calibration dropper 25 and the feeding port 12. Then, by arranging the second on-off valve 13 on one of the feeding ports 12, when the ink in the ink barrel 10 flows into the concentration detection barrel 22 through the liquid level difference, and the ink in the concentration detection barrel 22 fills to the upper calibration position, the control system 11 drives the second on-off valve 13 to close to avoid the ink continuing to flow into the concentration detection barrel 22, thereby accurately regulating the ink storage in the concentration detection barrel 22 and realizing the control of the ink flowing from the ink barrel 10 into the concentration detection barrel 22.

[0020] In order to automatically regulate the ink concentration in the ink barrel 10, as a preferred embodiment, the solvent supplement assembly 30 comprises a solvent barrel 31 connected to the ink barrel 10, and a third switch valve 32 is arranged at the connection between the ink barrel 10 and the solvent barrel 31. By arranging the solvent barrel 31 connected to the ink barrel 10 and the third switch valve 32 at the connection between the ink barrel 10 and the solvent barrel 31, when the ink concentration value measured by the ink concentration detection assembly 20 is higher than the set ink concentration range, the third switch valve 32 is opened by the control system, and then the solvent flows into the ink barrel 10 to reduce the ink concentration in the ink barrel 10, thereby automatically regulating the ink concentration in the ink barrel 10.

[0021] Specifically, the first drive assembly 23, the first switch valve 26, the second switch valve 13 and the third switch valve 32 are electrically connected to the control system 11, and the liquid level sensing assembly 23 is communicatively connected to the control system 11. After setting the required ink concentration range, the first drive assembly 23 is driven by the control system 11 to move the concentration detection barrel 22 below the installation height of the ink barrel 10, so that the ink in the ink barrel 10 can flow into the concentration detection barrel 22 and fill to the upper calibration position through the liquid level difference. At this time, the upper liquid level sensor in the liquid level sensing assembly 24 is turned on and sends a signal to the control system 11, and then the control system 11 drives the second valve 13 to close, so as to stop the ink in the ink barrel 10 from flowing into the concentration detection barrel 22, and drives the first drive assembly 23 to drive the concentration detection barrel 22 to return to the initial installation height above the ink barrel 10. Then the first switch valve 26 is opened by the control system 11, at this time the control system 11 starts timing, and the ink in the concentration detection barrel 22 starts to flow back to the ink barrel 10. When the ink in the concentration detection barrel 22 continues to flow out and the liquid level drops to the lower calibration position, the lower liquid level sensor in the liquid level sensing assembly 24 is turned on and sends a signal to the control system 11, so that the control system 11 drives the first switch valve 26 to close and stops timing, thereby measuring the current ink concentration time data in the ink barrel 10. When the measured ink concentration time data is less than the set ink concentration time range, the third switch valve 32 is opened by the control system 11, so that the solvent in the solvent barrel 31 can flow into the ink barrel 10 to regulate the ink concentration, thereby automatically regulating the ink concentration in the ink barrel 10 and effectively improving the work efficiency.

[0022] To sum up, in one or more embodiments of the present application, the present application provides an automatic control printing ink concentration device, which comprises an ink barrel and an ink concentration detection assembly arranged on one side of the ink barrel. The ink barrel is further connected with a solvent supplement assembly. The ink concentration detection assembly and the solvent supplement assembly are electrically connected to a control system. The control system is in communication connection with the ink concentration detection assembly. The ink concentration detection assembly is arranged on one side of the ink barrel, so that the ink concentration value in the ink barrel can be monitored in real time. The ink barrel is connected with the solvent supplement assembly. The ink concentration detection assembly and the solvent supplement assembly are electrically connected to the control system. The control system is in communication connection with the ink concentration detection assembly. The ink concentration obtained by the ink concentration detection assembly can be fed back to the control system. The control system drives the solvent supplement assembly to release solvent into the ink barrel, so as to automatically and real-timely adjust the ink concentration in the ink barrel, improve the work efficiency of the production line, and accurately control the ink concentration to the required range.
