TECHNICAL FIELD

[0001] The application relates to the technical field of paint viscosity detection, in particular to a dynamic constant-temperature detection device for the viscosity of water-based paint. BACKGROUND

[0002] In the field of paint industry, water-based paint is widely used in many industries such as building decoration, industrial painting, furniture manufacturing and automobile parts due to its low volatile organic compound emission, environmental friendliness and safety performance advantages, and has become one of the mainstream development directions of the paint industry. Viscosity, as a core physical performance index of water-based paint, directly determines the convenience of paint application, the quality of film formation, the uniformity of coating and the storage stability, and has a key influence on the final painting effect and product service life. In the production and preparation process of water-based paint, the viscosity needs to be strictly controlled within a reasonable range to ensure that the paint components are uniformly mixed and meet the process requirements of subsequent grinding, dispersion and other processing procedures. At the same time, in the paint storage and transportation link, the stability monitoring of viscosity is an important means to ensure the consistency of product quality, which can effectively avoid problems such as paint stratification, precipitation or caking caused by abnormal changes in viscosity. For the construction link, appropriate viscosity can ensure that the paint spreads uniformly on the substrate surface, forming a smooth and uniform film, and avoiding construction defects such as sagging, pinholes and brush marks. Therefore, whether it is quality control of production enterprises, stability monitoring of storage link or on-site adjustment of construction units, precise detection of the viscosity of water-based paint is indispensable.

[0020] Two strip-shaped through grooves 13 are arranged in the recess on the support table 1 and penetrate into the mounting cavity, and the two strip-shaped through grooves 13 movably clamp a pressure plate one 20 and a pressure plate two 25 respectively, the lower ends of the pressure plate one 20 and the pressure plate two 25 movably extend into the limiting blocks 23 which limit the pressure plate one 20 and the pressure plate two 25, and the mounting cavities below the pressure plate one 20 and the pressure plate two 25 are both mounted with spring sheets 24, the spring sheets 24 are provided with strip-shaped grooves, and the strip-shaped grooves on the spring sheets 24 are movably penetrated by the corresponding limiting blocks 23, and the two strip-shaped through grooves 13 are respectively provided with a female electrode one 22 and a female electrode two 27, the pressure plate one 20 is provided with a male electrode one 21 corresponding to the female electrode one 22, and the pressure plate two 25 is provided with a male electrode two 26 corresponding to the female electrode two 27, when the female electrode one 22 contacts the male electrode one 21, the female electrode two 27 and the male electrode two 26 are separated, when the female electrode one 22 is separated from the male electrode one 21, the female electrode two 27 and the male electrode two 26 are contacted, the female electrode two 27 and the male electrode two 26 are connected with two electrodes on the control heating pipe 16 power supply respectively, the support table 1 is further provided with a control panel 9, and the solenoid valve, the liquid flow sensor and the temperature sensor are electrically connected with the control panel 9, the servo motor one 14, the heating pipe 16 and the servo motor two 18 are also electrically connected with the control panel 9, and the control panel 9 is internally provided with a timer.

[0021] According to Figures 1-4 and Figures 9-10 , when in use, one of the two material cups 12 is first injected with an appropriate amount of water-based paint, and the detected temperature is set through the control panel 9; Subsequently, the glass heat preservation cover 2 is covered on the support table 1, in the process, the female electrode two 27 contacts the male electrode two 26, and cooperates with the control of the control panel 9, so that the heating pipe 16 can heat; At this time, the control panel 9 drives the servo motor one 14, so that the belt transmission structure 15 drives the mounting bracket 10 to rotate, and the material cup 12 injected with water-based paint is rotated to be directly above the other material cup 12; The control panel 9 opens the solenoid valve, so that the water-based paint flows from the upper material cup 12 to the lower material cup 12, in the process, the heating pipe 16 heats the flowing water-based paint, and the temperature sensor (for example, a probe type temperature sensor with a model of micro encapsulation PT100) monitors the temperature in real time and feeds back to the control panel 9; In the above process, the positions of the two material cups 12 can be exchanged through the servo motor one 14, so that the water-based paint can flow repeatedly, so as to be heated quickly, and in the process of exchanging, the solenoid valve is closed to avoid the water-based paint from dripping on other positions; When the temperature detected by the temperature sensor reaches the set detection temperature, the control panel 9 will reduce the heating power of the heating pipe 16, so as to ensure that the glass heat preservation cover 2 is in a dynamic constant temperature condition; When the water-based paint reaches the set temperature, the upper holding cup 12 no longer drips water-based paint, the lower holding cup 12 and the upper holding cup 12 are exchanged by the servo motor 14, and the water-based paint in the upper holding cup 12 flows to the lower holding cup 12 at this time. At this time, the timer in the control panel 9 starts, and the liquid flow sensor (for example, the liquid flow sensor of model Sensirion SLQ-QT500) starts at the same time.
