Description

Technical Field

[0001] The utility model relates to the technical field of liquid supply proportioning devices, in particular to a concentrated liquid supply proportioning device for dampening solution. Background Art

[0002] The dampening solution is also called wetting solution, water tank solution, and fountain solution. The dampening solution contains wetting agents that change the surface tension of the printing plate surface. The one with added wetting control components can help reduce the amount of ink while obtaining clear dots and vivid colors. Its pH buffer system can provide a continuous and stable pH value (4.5 - 5.5), and it is suitable for various water qualities. The anti-corrosion components help protect your machine. It is a highly concentrated product and needs to be diluted before use. First, the pH value cannot be too high or too low. Because the acidity is weak, the hydrophilic colloid layer is not easily formed, the surface tension of the dampening solution will drop sharply, the water content of the ink will become high, resulting in problems such as ink emulsification and serious dot gain. The ability of the dampening solution to clean the printing plate will also decrease, and it will affect the oxidation drying speed of the ink itself, and exacerbate the damage to the printing plate, corrode the sand grains in the blank part and the photosensitive material in the graphic part, reduce the printing resistance of the printing plate, and may damage the surface coating of alkaline paper.

[0003] Since the high-concentration original dampening solution needs to be diluted during use, generally, manual proportioning and dilution are carried out. Manual mixing and stirring of the original solution and the proportioning solution are labor-intensive and inefficient. Moreover, after the proportioning is successful, if the diluted solution is not used up for a long time, the original solution is likely to precipitate from the proportioning solution, resulting in a decrease in the mixing degree of the dampening solution in the concentrated liquid supply tank and unable to meet the production needs.

In the middle of the front end of the feed pipe 21, a stock solution pipe 24 is fixedly connected. At both ends of the stock solution pipe 24, a first stock solution tank 22 and a second stock solution tank 23 are fixedly connected. In the middle of the lower end of the reflux stirring pipe 6, a sampling pipe 12 is fixedly connected. On the front end of the sampling pipe 12, a sampling gate valve 13 is fixedly connected.

[0023] Before production, workers add stock solution into the first stock solution tank 22 and proportioning solution into the second stock solution tank 23 respectively. Start the feed motor 19, and then open the stock solution gate valves 25 of the first stock solution tank 22 and the second stock solution tank 23 respectively. Adjust the opening and closing of the stock solution gate valves 25 according to the required proportion. The stock solution and the proportioning solution are pumped by the feed motor 19 and enter the water inlet 18 on the solution mixing pipe 3. The mixed liquid entering the solution mixing pipe 3 is stirred and mixed in the solution mixing pipe 3 by the mixing auger 16 driven by the mixing motor 14. The mixed dampening solution flows into the supply tank 1 through the water outlet 17. Then start the supply motor 9 to pump the dampening solution in the supply tank 1 and pump the dampening solution to the production equipment through the supply pipe 11.

[0024] At the four corners of the bottom end of the supply tank 1, supply supports 2 are fixedly connected. At the front and rear parts of the bottom end of the outer side of the solution mixing pipe 3, mixing pipe racks 4 are fixedly connected. In the middle of the left side of the supply pipe 11, a supply motor 9 is arranged. At the front and rear ends of the bottom end of the supply motor 9, a supply machine frame 10 is fixedly connected.

[0025] When a certain amount of dampening solution in the supply tank 1 has been used and there is still some left unused, before reuse, a certain amount of dampening solution needs to be collected for testing by opening the sampling gate valve 13 on the sampling pipe 12 to check whether the mixing degree of the dampening solution has decreased. Then, start the reflux motor 7 to pump the dampening solution at the bottom of the supply tank 1 to the upper part of the supply tank 1, so that the dampening solution is remixed to improve the mixing degree of the dampening solution.

[0026] Working principle: Before production, workers add the stock solution into the first stock solution tank 22 and the proportioning solution into the second stock solution tank 23 respectively. Start the feeding motor 19, and then open the stock solution gate valves 25 of the first stock solution tank 22 and the second stock solution tank 23 respectively, and adjust the opening and closing of the stock solution gate valves 25 according to the required proportion. The stock solution and the proportioning solution are pumped through the feeding motor 19 and enter the water inlet 18 on the solution mixing pipe 3 from the feeding pipe 21. The mixed solution entering the solution mixing pipe 3 is stirred and mixed in the solution mixing pipe 3 by the mixing auger 16 driven by the mixing motor 14. The well-mixed dampening solution flows into the supply tank 1 through the water outlet 17. Then, start the supply motor 9 to pump the dampening solution in the supply tank 1 and pump the dampening solution to the production equipment through the supply pipe 11; When a certain amount of dampening solution in the supply tank 1 has been used and there is still some left unused, before reuse, a certain amount of dampening solution needs to be collected for testing by opening the sampling gate valve 13 on the sampling pipe 12 to check whether the mixing degree of the dampening solution has decreased. Then, start the reflux motor 7 to pump the dampening solution at the bottom of the supply tank 1 to the upper part of the supply tank 1, so that the dampening solution is remixed to improve the mixing degree of the dampening solution.
