Description

Technical Field

[0001] The utility model relates to the technical field of coating processing devices, and more specifically to a three-knife sealing liquid tank. Background Art

[0002] The conventional coating form is that the liquid tank is below the anilox roller, and the anilox roller is immersed in the liquid tank. When the anilox roller rotates, the entire roller surface will be stained with the liquid. When the liquid tank is below, there are holes on the top, so it does not need to be sealed and the liquid will not overflow. Now the liquid tank needs to be turned 90 degrees and placed horizontally parallel to the anilox roller. In this way, the direction of the liquid tank close to the anilox roller must be sealed, otherwise the liquid will flow out from the bottom, so a sealed liquid tank is designed.

[0003] The Chinese patent with patent application number CN202123266590.7 discloses a high-precision sealed liquid tank, including a slider seat, a slider is slidably mounted on the outer surface of the slider seat, a liquid tank support seat is arranged on the outer surface of the slider, a liquid tank mounting shaft is arranged on the outer surface of the liquid tank support seat, and a liquid tank is arranged on the outer surface of the liquid tank mounting shaft. When the sealed liquid tank is working, the return port at the lower position should be blocked, and the material is fed through the feed port. When the material level in the sealed space rises, the material is returned through the return port at the upper position. When not working, the return port at the lower position is opened, the material level is lowered, and the forward and backward propulsion power of the liquid tank causes the liquid tank support seat to withdraw backward, and the liquid tank support seat and the liquid tank mounting shaft withdraw backward together with the liquid tank. The rotation of the liquid tank mounting shaft is adjusted by the upper angle adjustment knob and the lower angle adjustment knob. The liquid tank mounting shaft drives the liquid tank to rotate so that the liquid tank flips upward, which is convenient for cleaning the liquid tank.

[0004] Then, combined with the drawings in the specification, it can be seen that the sealing liquid tank is sealed by a sealing gasket, but when the anilox roller is at a high speed, it is easy for external air to adhere to the pits on the anilox roller, causing bubbles to appear on the surface of the anilox roller, which cannot be fully coated with liquid, affecting product quality.

[0014] Technical effects and advantages of the utility model:

[0015] 1.

[0024] The inner cavity of the sealing liquid tank 4 is provided with a middle knife seat 10, and a flow hole 11 is opened on the surface of the middle knife seat 10. A spring 12 is provided on one side of the middle knife seat 10, and a middle scraper 13 is provided on the other side of the middle knife seat 10. A middle cover plate 14 is provided on one side of the middle scraper 13. The middle scraper 13 is supported by the middle knife seat 10, and the middle scraper 13 is conveniently fixed by the middle cover plate 14. By squeezing the middle scraper 13 by the anilox roller 2, the middle knife seat 10 can be bent to squeeze the spring 12, so that the middle scraper 13 and one end of the upper scraper 17 and the lower scraper 19 are all in contact with the anilox roller 2, thereby improving the bonding effect.

[0025] As attached Figure 1 As shown, the bottom of the sliding device 3 is connected to the base 1, and a plurality of pits are provided on the surface of the anilox roller 2. One end of the lower scraper 19, the upper scraper 17, and the middle scraper 13 are in contact with the wall of the anilox roller 2.

Through the plurality of pits, the liquid in the middle of the sealing liquid tank 4 can be allowed to enter the pits, and gas can be avoided in the pits, thereby achieving the effect of full liquid coating.

[0026] As attached Figure 1 , 2 As shown, the moving end of the power device 5 is connected to the wall of the sealing liquid tank 4, one end of the spring 12 is in contact with the inner wall of the sealing liquid tank 4, and the connection between the middle knife seat 10 and the wall of the sealing liquid tank 4 is set to an elastic material.

[0027] As attached Figure 1 , 2As shown, the upper cover plate 18 and the upper scraper 17 correspond to the lower cover plate 20 and the lower scraper 19 respectively. The upper scraper 17 and the lower scraper 19 are respectively arranged on the upper and lower sides of the anilox roller 2 close to the sealing liquid tank 4. The upper scraper 17 and the lower scraper 19 can make the upper cavity 15 and the lower cavity 16 of the inner cavity of the sealing liquid tank 4 form a sealing structure to improve the use effect.

[0028] As attached Figure 1 , 2 As shown, the inner cavity of the sealing liquid tank 4 is divided into an upper cavity 15 and a lower cavity 16 by the middle scraper 13 and the middle knife seat 10, and the upper cavity 15 and the lower cavity 16 are connected by the flow hole 11. Through the upper cavity 15 and the lower cavity 16, the middle part of the sealing liquid tank 4 can be divided into two cavities, and they are connected by the flow hole 11, so that the liquid entering the middle part of the lower cavity 16 can enter the interior of the upper cavity 15 through the flow hole 11, and the gas entering the middle part of the lower cavity 16 can enter the middle part of the upper cavity 15 through the flow hole 11, and then be discharged through the exhaust hole 6, thereby improving the use effect.

[0029] As attached Figure 1 , 2 As shown, the upper chamber 15 is connected to the drainage hole 8, the lower chamber 16 is connected to the liquid inlet 9, and the upper chamber 15 is connected to the exhaust hole 6. The liquid can be easily discharged through the drainage hole 8, and the liquid can be injected into the interior of the lower chamber 16 through the liquid inlet 9, and the gas can be discharged through the exhaust hole 6, thereby improving the use effect.

[0030] Working principle of the utility model: when in use, the anilox roller 2 rotates counterclockwise, and the power device 5 is started to control the sealing liquid tank 4 to approach the anilox roller 2, until the upper scraper 17 and the lower scraper 19, and one end of the middle scraper 13 are in contact with the anilox roller 2, at which time the middle scraper 13 drives the middle knife seat 10 to compress the spring 12, and the middle knife seat 10 is deformed;

[0031] Liquid is injected into the lower chamber 16 through the liquid inlet 9, and the liquid flows into the middle of the upper chamber 15 through the flow hole 11 and is discharged through the drain hole 8;

[0032] When the anilox roller 2 rotates at high speed, the pits avoided by the anilox roller 2 will bring the gas into the lower chamber 16. At this time, liquid and gas will coexist in the pits on the surface of the anilox roller 2. As the anilox roller 2 rotates, the gas and liquid in the pits will be squeezed at the contact point between the middle scraper 13 and the anilox roller 2, so that the gas is discharged, and the liquid will continue to rotate in the pits toward the upper chamber 15.

[0033] When the pit corresponds to the upper cavity 15, the pit will be filled with liquid again, so that when the anilox roller 2 drives the pit to rotate out of the upper cavity 15, the pit is full of liquid;

[0034] The gas blocked by the middle scraper 13 will be located in the middle of the lower chamber 16 and will flow into the interior of the upper chamber 15 through the flow hole 11 and reach the exhaust device 7 through the exhaust hole 6. The exhaust device 7 blocks the liquid and discharges the gas.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
