Description

Technical Field

[0001] The invention relates to a printing system, more specifically to an automatic liquid replenishing device for a printing table. Background Art

[0002] With the development of the electronics industry, many industries need to use various printing methods. The method of printing and replenishing liquid is manual replenishment, which generally has a high error rate, low efficiency, and troublesome operation.

[0003] The Chinese invention patent with the authorization publication number CN117002135 A discloses a printing press fountain solution circulation system, which includes a housing, a circulation pump, a liquid storage tank, a filtering system, and a control system.

[0004] The above technical solution has obvious defects. After the liquid in the liquid storage tank is consumed, it needs to be manually added, which is inefficient and prone to errors. Summary of the invention

[0005] In view of the shortcomings and defects of the prior art, the present invention provides an automatic liquid replenishing device for a printing table, which adds an automatic liquid replenishing function on the basis of a fountain solution circulation system of a printing press.

[0006] The present invention is realized by the following technical scheme. The present invention includes a main liquid tank, a No. 1 fluid on-off element, a physical quantity converter, a liquid supply tank, a controller, an alarm, a No. 2 fluid on-off element, and a printing table. The main liquid tank is connected to the liquid supply tank through the No. 1 fluid on-off element, and the liquid supply tank is connected to the printing table through the No. 2 fluid on-off element. A physical quantity converter is installed on the liquid supply tank. The physical quantity converter converts the continuously changing physical quantity in the liquid supply tank into a digital signal and transmits it to the controller. The controller controls the No. 1 fluid on-off element, the alarm, and the No. 2 fluid on-off element to act according to the digital signal. The present invention also includes a fluid power element, which can be a quantitative pump or a variable pump. The fluid power element is installed between the main liquid tank and the liquid supply tank. The alarm will send a signal when the physical quantity of the liquid supply tank reaches a certain value. The signal will be received by humans and converted into a neural signal and transmitted to the brain. The signal can enable humans to perceive the shape, color, size, position, and movement of objects. The No. 1 fluid on-off element includes an actuator, and the actuator can change the flow area of ​​the No. 1 fluid on-off element. The second fluid on-off element includes an actuator, which can change the flow area of ​​the first fluid on-off element. There is a height difference between the main liquid tank and the liquid supply tank. There is a height difference between the liquid supply tank and the printing table. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a schematic diagram of the present invention. DETAILED DESCRIPTION

[0008] like Figure 1As shown, the present invention includes a main liquid tank 1, a No. 1 fluid on-off element 3, a physical quantity converter 4, a liquid supply tank 5, a controller 6, an alarm 7, a No. 2 fluid on-off element 8, and a printing table 9. The main liquid tank 1 is connected to the liquid supply tank 5 through the No. 1 fluid on-off element 3, and the liquid supply tank 5 is connected to the printing table 9 through the No. 2 fluid on-off element 8. The physical quantity converter 4 is installed on the liquid supply tank 5. The physical quantity converter 4 converts the continuously changing physical quantity in the liquid supply tank 5 into a digital signal and transmits it to the controller 6. The controller 6 controls the No. 1 fluid on-off element 3, the alarm 7, and the No. 2 fluid on-off element 8 to operate according to the digital signal. The physical quantity converter 4 can detect the liquid level, temperature, pH value, and other indicators of the liquid supply tank 5.

[0009] The present invention further comprises a fluid power element 2 , which is a quantitative pump and is installed between the main liquid tank 1 and the liquid supply tank 5 .

[0010] The alarm device 7 is an audible and visual alarm device. When the liquid level, temperature, pH value and other indicators of the liquid supply tank 5 exceed the standard, the alarm device 7 will generate an audible and visual alarm signal.

[0011] The No. 1 fluid on-off element 3 is an electromagnetic ball valve, which controls the on-off of the fluid.

[0012] The No. 2 fluid on-off element 8 is an electromagnetic ball valve, which controls the on-off of the fluid.

[0013] There is a height difference between the main liquid tank 1 and the liquid supply tank 5 . The liquid level of the main liquid tank 1 is higher than that of the liquid supply tank 5 , which is conducive to the flow of fluid into the liquid supply tank.

[0014] There is a height difference between the liquid supply tank 5 and the printing table 9 . The liquid level of the liquid supply tank 5 being higher than the printing table 9 is conducive to the flow of fluid into the printing table 9 .
