Description

Technical Field

[0001] The present invention relates to the technical field of coating fluidity detection, and in particular to a device and method for detecting fluidity of a water-based coating. Background Art

[0002] Any coating that uses water as a solvent or dispersion medium can be called a water-based coating. Based on the type of binder in the coating, water-based coatings are divided into two categories: natural water-based coatings made from natural substances or minerals and petrochemical water-based coatings made from artificial synthetic resins. Water-based coatings include three types: water-soluble coatings, water-dilutable coatings, and water-dispersible coatings. When testing water-based coatings, it is necessary to test the fluidity of the coating, that is, the viscosity of the coating, to ensure the quality of the coating.

[0003] Most of the existing water-based paint fluidity tests use the amount of paint flow per unit time to test the fluidity of water-based paint. However, bubbles will be generated during the paint application process. The presence of bubbles will reduce the apparent viscosity of the paint, giving people the illusion that the paint has good fluidity. This is because bubbles in the paint are equivalent to a lubricant, which will reduce the internal friction between paint molecules, causing the measured viscosity data to be lower than the actual value, thereby affecting the judgment of the true fluidity of the paint.

[0018] A method for detecting fluidity of a water-based paint, applicable to the above-mentioned device for detecting fluidity of a water-based paint, comprises the following steps:

[0019] S1: The staff pours the water-based paint to be tested into the pretreatment box, and the receiving plate moves downward under the action of the water-based paint's own gravity;

[0020] S2: Under the gravity of the water-based paint on the top of the receiving plate, the first threaded barrel rotates to stir the water-based paint, and at the same time, the defoaming agent is sprayed out from the reagent barrel;

[0021] S3: When the receiving plate moves downward to a certain position, the baffle contacts the first discharge pipe, and the first discharge pipe pushes the baffle upward, so that the discharge port is exposed to the inside of the water-based paint, and the water-based paint enters the inside of the first discharge pipe through the discharge port;

[0022] S4: The water-based paint falls into the interior of the detection tube through the guide plate, and the float moves upward under the action of buoyancy. When the water-based paint in the detection tube rises to a certain position, the discharge plate blocks the first discharge pipe to keep the water-based paint in the detection tube at a certain height;

[0023] S5: The staff opens the valve to conduct a fluidity test. The height of the water-based paint inside the test tube begins to drop, the float moves downward, the feed plate rotates in the opposite direction, and the water-based paint falls from the inside of the feed chute again to replenish the water-based paint inside the test tube. The water-based paint inside the test tube remains at a stable height.

[0024] S6: As the amount of water-based paint inside the pretreatment box decreases, the receiving plate slides upward under the action of the first spring. At this time, the double-groove pulley rotates, causing the hammer head to hammer the guide plate to eliminate bubbles.

[0025] The present invention provides a water-based paint fluidity detection device, which has the following beneficial effects:

[0026] 1. Through the setting of the pretreatment mechanism, the agglomerated resin can be broken up by stirring, so that it can be evenly distributed in the coating, which helps to improve the fluidity and stability of the coating and make the fluidity test results more representative. During the stirring process, the bubbles inside the coating will rupture and escape under the action of shear force, thereby reducing the interference of bubbles on the fluidity test. At the same time, the defoaming agent can ensure that no new bubbles are generated during the stirring of the water-based coating.

[0027] 2. Through the setting of the detection mechanism, the height of the water-based paint inside the detection tube can be kept unchanged, ensuring that the gravitational potential energy of the paint during the test is always consistent, providing stable dynamic conditions for its flow. This makes the driving force of the paint when it flows inside the detection tube relatively stable, avoiding flow rate fluctuations caused by differences in gravitational potential energy due to changes in the height of the paint, thereby improving the accuracy of the fluidity test results.

[0028] 3. Through the setting of the debubble mechanism, the bubbles on the guide plate can be removed for a second time, so that the bubbles that have not been removed after the pre-treatment mechanism are completely removed, and the influence of bubbles on the fluidity of the coating is eliminated to the greatest extent, so as to obtain more accurate test results.

[0051] Specifically, the working process or working principle of the water-based paint fluidity detection device is as follows: the staff pours the water-based paint to be detected into the interior of the pretreatment box 201, and under the action of the gravity of the water-based paint itself, the receiving plate 202 moves downward, so as to compress the first spring 203. When the receiving plate 202 moves downward, the first threaded rod 204 can be inserted into the interior of the first threaded cylinder 205, so that the first threaded cylinder 205 can rotate. When the first threaded cylinder 205 rotates, it can drive the first sliding cylinder 206 to rotate, and the rotating first sliding cylinder 206 06 can drive the gear rod 208 to rotate, and when the receiving plate 202 moves downward, the gear rod 208 can also slide inside the tooth groove 207. When the first threaded cylinder 205 rotates, the water-based paint can be stirred. When the first pulley 211 rotates, it can drive the double-groove pulley 217 to rotate. The rotating double-groove pulley 217 can drive the second threaded rod 216 to move downward, so that the piston plate 215 can move downward inside the medicine barrel 213, so that the defoaming agent inside the medicine barrel 213 can be sprayed into the interior of the pretreatment box 201.

[0052] When the receiving plate 202 moves downward to a certain position, the baffle 303 contacts the first discharge pipe 304, and the baffle 303 can be moved upward under the action of the first discharge pipe 304, thereby driving the first sliding rod 301 to slide upward inside the receiving plate 202, thereby compressing the second spring 302. At this time, the first discharge pipe 304 is inserted into the top of the receiving plate 202, so that the discharge port 305 is exposed to the inside of the water-based paint, and the water-based paint can enter the inside of the first discharge pipe 304 through the discharge port 305, and the water-based paint falls onto the surface of the guide plate 402 through the first discharge pipe 304, so that the water-based paint can flow on the surface of the guide plate 402, and the water-based paint on the guide plate 402 can flow into the inside of the detection cylinder 401.

[0053] When more and more water-based paint is added to the detection cylinder 401, the float 405 can move upward, thereby driving the third threaded rod 406 to move upward, thereby driving the second threaded cylinder 407 to rotate, and the rotating second threaded cylinder 407 can drive the first gear 408 to rotate, and the rotation of the first gear 408 can drive the two second gears 409 to rotate, and the rotating second gear 409 can drive the blanking plate 410 to rotate, and the water-based paint in the second discharge pipe 413 can fall through the blanking trough 411 on the blanking plate 410. When the water-based paint in the detection cylinder 401 increases, the float 405 can move upward, thereby driving the third threaded rod 406 to move upward, thereby driving the second threaded cylinder 407 to rotate, and the rotating second threaded cylinder 407 can drive the first gear 408 to rotate, and the rotation of the first gear 408 can drive the two second gears 409 to rotate, and the rotating second gear 409 can drive the blanking plate 410 to rotate, and the water-based paint in the second discharge pipe 413 can fall through the blanking trough 411 on the blanking plate 410. After the water-based paint rises to a certain position, the discharge plate 410 blocks the first discharge pipe 304, so that the water-based paint inside the detection cylinder 401 maintains a certain height. When the staff opens the valve 415 to perform a fluidity test, the height of the water-based paint inside the detection cylinder 401 begins to decrease, causing the float 405 to move downward, thereby allowing the discharge plate 410 to rotate in the opposite direction, allowing the water-based paint to fall again from the inside of the discharge trough 411, thereby replenishing the water-based paint inside the detection cylinder 401 and keeping the water-based paint inside the detection cylinder 401 at a stable height.

[0054] When the double-groove pulley 217 rotates, the third pulley 502 can be driven to rotate, the rotating third pulley 502 can drive the rotating shaft 501 to rotate, the rotation of the rotating shaft 501 can drive the first bevel gear 503 to rotate, the rotation of the first bevel gear 503 can drive the second bevel gear 505 to rotate, the rotating second bevel gear 505 can drive the third gear 504 to rotate, the rotating third gear 504 can drive the fourth gear 506 to rotate, the rotation of the fourth gear 506 can drive the eccentric plate 507 to rotate eccentrically, and the eccentrically rotating eccentric plate 507 can The connecting column 508 is driven to move up and down, thereby driving the double-toothed plate 509 to slide up and down on the side of the bracket 1. The up and down sliding of the double-toothed plate 509 can drive the two fifth gears 510 to rotate, and then drive the third threaded cylinder 511 to rotate, so that the fourth threaded rod 512 can move back and forth inside the third threaded cylinder 511. The back and forth movement of the fourth threaded rod 512 can drive the hammer head 513 to hammer on the side of the guide plate 402. The hammering of the hammer head 513 can cause the guide plate 402 to vibrate at a high frequency, thereby eliminating bubbles generated during the falling process of the water-based paint.
