Description

Technical Field

[0001] The utility model relates to the technical field of ink production, in particular to a defoaming device for ink production. Background Art

[0002] Ink is a liquid containing pigments or dyes, mainly used for writing or painting. During the production process of ink, due to the fact that water-soluble materials are prone to generate and mix with micro-bubbles during the grinding and stirring process, it will cause greater problems when printing and coating the surface of an object, and does not meet the quality standards. Therefore, a defoaming device needs to be used for defoaming to improve the quality.

[0003] However, when the existing defoaming device is in use, the stirring method of the stirring rod is single, and some bubbles at the bottom cannot float up quickly, resulting in a low defoaming efficiency, causing the entire defoaming process to take a long time and affecting the work efficiency.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a Figure 1-8 defoaming device for ink production as shown, including a housing assembly 1. A stirring assembly 2 is installed at the lower end inside the housing assembly 1. The housing assembly 1 includes a stirring cylinder 101, and the stirring cylinder 101 has only an opening at the top. A top cover 102 is provided at the top of the stirring cylinder 101.

[0028] Furthermore, a liquid inlet pipe 104 is fixedly penetrated through one side of the top end of the top cover 102. A reduction motor 106 is installed in the middle of the bottom end of the stirring cylinder 101, and the output shaft of the reduction motor 106 is fixedly connected to the bottom end of the rotating rod 201. A liquid outlet pipe 105 is fixedly penetrated through one side of the bottom end of the stirring cylinder 101. A vacuum pump 103 is installed in the middle of the top end of the top cover 102, and the input end of the vacuum pump 103 is communicated with the inside of the stirring cylinder 101. The installation position of the vacuum pump 103 can also be on the stirring cylinder 101, not limited to the top cover 102;

[0029] The stirring assembly 2 includes a rotating rod 201, and the rotating rod 201 movably penetrates through the middle of the bottom end of the stirring cylinder 101 through a sealed bearing. A fixing block 202 is fixedly arranged at the top end of the rotating rod 201, and fixing rods 203 are fixedly arranged on both sides of the fixing block 202. Stirring rods 204 are arranged on both sides of the fixing block 202. One end of a fixing rod 203 movably inserts into the middle of one end of a stirring rod 204 close to the fixing block 202 through a sealed bearing. A plurality of inclined sawteeth 206 distributed in an annular array are integrally formed on the outer side wall of the stirring rod 204 close to the fixing block 202. Rotating plates 205 are fixedly arranged at the top end and the bottom end of the stirring rod 204, and both rotating plates 205 are arc-shaped. The two rotating plates 205 are centrosymmetrically arranged. The arc-shaped setting can better stir the liquid at the bottom upward and improve the stirring efficiency. A limiting block 207 is movably sleeved on the rotating rod 201, and the bottom end of the limiting block 207 is fixedly connected to the inner wall of the bottom end of the stirring cylinder 101. A limiting ring 210 is integrally formed around the top edge of the limiting block 207. A plurality of inclined tooth grooves 208 distributed in an annular array are formed at the top end of the limiting ring 210, and the inclined tooth grooves 208 are adapted to the inclined sawteeth 206. Both the inclined sawteeth 206 and the inclined tooth grooves 208 are inclined, and the transmission is stable and smooth. Through the settings of the vacuum pump 103 and the stirring assembly 2, defoaming can be carried out through the stirring of the stirring assembly 2, and at the same time, vacuum defoaming is carried out through the vacuum pump 103. Double defoaming improves the defoaming efficiency. And while the stirring rod 204 is driven to rotate and stir by the rotating rod 201 and the fixing block 202, due to the settings of the plurality of inclined sawteeth 206 and the plurality of inclined tooth grooves 208, the stirring rod 204 itself can be driven to rotate, thereby driving the two rotating plates 205 on the stirring rod 204 to rotate, stirring the liquid at the bottom upward and the liquid at the top downward, so that the bubbles at the bottom can quickly float upward, thus greatly improving the defoaming speed. At the same time, the ink can be better stirred, and the ink and the water-soluble materials can be mixed more evenly, improving the quality of the ink.

[0030] Secondly, a plurality of supporting legs 107 distributed in an annular array are integrally formed at the bottom edge of the stirring cylinder 101. An annular limiting groove 108 is formed around the middle of the inner wall of the stirring cylinder 101. A limiting convex block 209 is fixedly arranged at one end of the stirring rod 204 away from the fixing block 202, and the limiting convex block 209 is adapted to the annular limiting groove 108. One end of the limiting convex block 209 located inside the annular limiting groove 108 is circular. The limiting convex block 209 is made of polytetrafluoroethylene, and polytetrafluoroethylene has an extremely small coefficient of friction, which can reduce the frictional force and reduce the wear between the limiting convex block 209 and the inner wall of the annular limiting groove 108. The settings of the limiting convex block 209 and the annular limiting groove 108 can play a role in supporting the stirring rod 204, improving the stability of the stirring rod 204 and preventing the stirring rod 204 from shaking up and down.

[0031] The working principle of the present utility model:

[0032] During use, close the valve on the liquid outlet pipe 105, and inject ink with water-soluble materials into the interior of the mixing drum 101 through the liquid inlet pipe 104. Immediately after that, close the valve on the liquid inlet pipe 104, turn on the vacuum pump 103 and the reduction motor 106. The vacuum pump 103 evacuates the interior of the mixing drum 101, reducing the internal pressure of the mixing drum 101, causing the bubbles in the ink to quickly rise and disappear. At the same time, the reduction motor 106 drives the rotating rod 201 and the fixing block 202 to rotate, and the fixing block 202 drives the fixing rod 203 and the stirring rod 204 to rotate for stirring. At the same time, while the stirring rod 204 rotates horizontally, due to the arrangement of a plurality of inclined sawteeth 206 and a plurality of inclined tooth grooves 208, it can drive the stirring rod 204 itself to rotate, thereby driving the two rotating plates 205 on the stirring rod 204 to rotate, stirring the liquid at the bottom upward and the liquid at the top downward, so that the bubbles at the bottom can quickly float up.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
