Description

Technical Field

[0001] The present invention relates to the technical field of water-based paint detection, and more specifically to a water-based paint fluidity detection device. Background Art

[0002] For coatings manufacturers, the fluidity of waterborne coatings is a key indicator of product quality. By testing the fluidity, the quality stability of different batches of products can be guaranteed. For example, in large-scale production, factors such as slight differences in raw materials and fluctuations in production process parameters may affect the fluidity of the coating. If the fluidity of a batch of coating deviates significantly from the normal range, it may mean that there is a problem in the production process, such as incorrect raw material ratios, insufficient mixing time, etc. By regularly testing the fluidity, companies can detect these problems in a timely manner and take measures to correct them, thereby ensuring that each batch of products can meet consistent quality standards.

[0003] Meet product specifications: Each water-based paint is designed and produced with specific flow specifications. These requirements are determined based on the intended use of the paint. For example, water-based automotive paint for spraying needs to have good flow in order to form an even, smooth coating on the surface of the car. Testing the flow ensures that the product meets these pre-set specifications. If the flow does not meet the requirements, it may cause uneven coating thickness, orange peel (uneven surface, similar to orange peel) and other quality problems, affecting the appearance and performance of the product.

[0004] Optimize the selection of construction process in terms of construction performance evaluation: Different construction methods (such as brushing, roller coating, spraying, etc.) have different requirements for the fluidity of the paint. For example, brushing requires the paint to have good leveling properties, that is, the paint can quickly level after being brushed, covering the traces left by the brush. By testing the fluidity of water-based paint, it can help construction personnel choose the most appropriate construction process. If the fluidity of the paint is too poor, it may be more suitable to use roller coating rather than brushing, because roller coating can apply greater pressure to promote better spreading of the paint. On the contrary, if the fluidity of the paint is very good, spraying may be a more efficient construction method.

[0005] Existing devices for detecting the fluidity of water-based paints mostly perform detection work by means of inclined flow, and their functions are single and the detection effect is not intuitive enough. In view of this, we propose a device for detecting the fluidity of water-based paints. Summary of the invention

A water-based paint fluidity detection device according to claim 6, characterized in that: The inner wall of the adjusting sleeve (905) is provided with at least two spiral grooves (9051) in a centrally symmetrical manner, and the two spiral grooves (9051) are connected via a linear groove (9052), and the groove depth at the input end of the spiral groove (9051) and the linear groove (9052) is smaller than the groove depth at the output end of the spiral groove (9051) and the linear groove (9052); wherein a drop is provided at the connection between the spiral groove (9051) and the linear groove (9052).

8. A water-based paint fluidity detection device according to claim 7, characterized in that: The push rod (801) works in a reciprocating stroke, causing the extrusion protrusion (803) to slide along the spiral groove (9051) and the linear groove (9052), causing the adjustment sleeve (905) to drive the central gear (904) to rotate, causing the planetary gear (906) to synchronously rotate and drive the roller brush layer B (9082) on the outer surface of the adjustment wrapping sleeve (908) to overlap and fit the outer surface of the connecting support arc plate (902), so that a circumferential roller structure is formed between the roller brush layer B (9082) and the roller brush layer A (9011).

9. A water-based paint fluidity detection device according to claim 7, characterized in that: The push rod (801) works in a reciprocating return stroke, causing the extrusion protrusion (803) to slide along the spiral groove (9051) and the linear groove (9052), causing the adjustment sleeve (905) to drive the central gear (904) to rotate, causing the planetary gear (906) to synchronously rotate and drive the brush layer (9083) on the outer surface of the adjustment wrapping sleeve (908) to be exposed. At this time, the extrusion protrusion (803) is close to the sliding output end of the spiral groove (9051), and is reversely driven by the push rod (801) to slide along the sliding output end of the spiral groove (9051) to the input end of the spiral groove (9051), and one side of the brush layer (9083) is squeezed through the arc through the notch, so that the brush layer (9083) attached to the outer surface of the adjustment wrapping sleeve (908) is squeezed to form a brush structure.
