Description

Technical Field

[0001] This utility model relates to the field of testing devices, specifically a viscosity testing device. Background Technology

[0002] Water-based coatings are coatings that use water as a solvent or dispersion medium. They are environmentally friendly and safe, and are widely used in many fields. Viscosity is one of the important performance indicators of water-based coatings. Testing the viscosity helps to control the application performance and quality of the coatings.

[0003] Chinese patent CN202323561601.3 discloses a coating viscosity testing device, including a base and a cup holder bracket on the base. The cup holder bracket is equipped with a heating component for supporting and heating a viscosity cup. The heating component includes a heating sleeve and multiple heat-conducting sleeves that can be inserted into the heating sleeve. The multiple heat-conducting sleeves have different inner diameters to accommodate viscosity cups of different sizes. The inner wall of the heating sleeve has an annular groove. This invention uses multiple heat-conducting sleeves with different inner diameters. According to different viscosity cup sizes, a suitable heat-conducting sleeve is selected and inserted into the heating sleeve. The heat-conducting sleeve fills the gap between the heating wire and the viscosity cup, preventing heat loss and improving the heating effect. Simultaneously, the periphery of the heat-conducting sleeve has multiple protrusions for insertion into the heating sleeve. The protrusions cooperate with the slots to define the position of the heat-conducting sleeve, and the protrusions increase the heated area of ​​the heat-conducting sleeve, further improving heat conduction efficiency.

[0004] While existing paint viscosity testing devices can solve the problem of low heating efficiency due to the gap between the heating wire and the viscosity cup, which allows heat to easily leak out, they also have limitations. The paint is only applied to a single material, making it impossible to simultaneously test the viscosity of the paint on different materials. This results in a small testing range, reduced testing efficiency, and the need to perform multiple tests on the same paint.

[0005] Therefore, a viscosity detection device is proposed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a viscosity detection device to solve the problem mentioned in the background art that the coating adheres to a relatively simple material, making it impossible to simultaneously detect the viscosity of the coating between different materials, resulting in a small detection range, reduced detection efficiency, and the need to perform multiple tests on the same coating.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a viscosity testing device, including a device body, a testing module is arranged below the device body, a sample tray is installed below the testing module, and an auxiliary module is arranged at the bottom of the sample tray; the testing module includes an electric push rod, a test box, a slide groove, a movable rod, a spring and a scale, the test box is installed at the bottom of the electric push rod, the slide groove is reserved inside the test box, the movable rod is arranged inside the slide groove, the top of the movable rod is installed with a spring, and the outer wall of the movable rod is provided with a scale.

[0008] Preferably, the scale and the movable rod are glued together, and the movable rod forms a sliding structure with the inspection box through a groove, and the inspection box and the spring are fixedly connected.

[0009] Preferably, the detection module further includes a pressure plate, a screw, and a washer. The bottom of the movable rod is provided with a pressure plate, and a screw is installed on one side of the pressure plate, while a washer is provided on the other side of the pressure plate.

[0010] Preferably, the sample tray includes a base, a slot, a barrier, and a separator. The base has a slot pre-reserved inside, and a barrier is provided above the base. A separator is installed inside the barrier.

[0011] Preferably, there are four separators, and the four separators are made of different materials, and the material of each separator is the same as the material of the corresponding gasket above it.

[0012] Preferably, the auxiliary module includes a base plate, a fixing plate, a clamping plate, and a heating element. The fixing plate is disposed above the base plate, and the clamping plate is mounted above the fixing plate. A heating element is disposed at the end of the clamping plate.

[0013] Preferably, the card plate forms an engaging structure with the base through a card slot, and the base and the heating element are tightly fitted together.

[0014] The advantages of this utility model are:

[0015] 1. This utility model uses the cooperation between an electric push rod and an inspection box to have a classification and detection function. The viscosity of water-based coatings on different materials is detected by different moving rods. The viscosity can be directly observed by a scale, which is convenient for the testers to record.

The testing module 2 includes an electric push rod 201, a test box 202, a slide groove 203, a movable rod 204, a spring 205, and a scale 206. The test box 202 is mounted at the bottom of the electric push rod 201, and a slide groove 203 is reserved inside the test box 202. A movable rod 204 is disposed inside the slide groove 203, and the movable rod 205... A spring 205 is installed on the top of the movable rod 204, and a scale 206 is provided on the outer wall of the movable rod 204. The scale 206 and the movable rod 204 are glued together, and the movable rod 204 forms a sliding structure with the inspection box 202 through the slide groove 203. The inspection box 202 and the spring 205 are fixedly connected. With this setting, it has a classification detection function. The viscosity of water-based coatings on different materials can be detected by different movable rods 204. The viscosity can be directly observed by the scale 206, which is convenient for the testers to record.

[0026] Please see Figure 3 As shown, the detection module 2 also includes a pressure plate 207, a screw 208, and a gasket 209. The pressure plate 207 is provided at the bottom of the movable rod 204, and the screw 208 is installed on one side of the pressure plate 207. The gasket 209 is provided on the other side of the pressure plate 207. This arrangement facilitates disassembly and replacement. After long-term use, the gasket 209 is prone to wear, which affects the viscosity detection results. Regular maintenance and replacement are required to reduce the error of the detection results.

[0027] Please see Figure 2 and Figure 4 As shown, the sample tray 4 includes a base 401, a slot 402, a baffle 403, and a separator 404. The slot 402 is reserved inside the base 401, and the baffle 403 is set on the top of the base 401. The separator 404 is installed inside the baffle 403. There are four separators 404, and the four separators 404 are all made of different materials. The material of each separator 404 is the same as the material of the corresponding gasket 209 above it. This setting facilitates the simultaneous detection of the viscosity of water-based coatings on multiple materials. At the same time, the modular design allows the sample tray 4 to be directly pulled out and replaced with a new sample tray 4 after the test is completed, thereby improving the testing efficiency.

[0028] Please see Figure 2As shown, the auxiliary module 3 includes a base plate 301, a fixing plate 302, a clamping plate 303, and a heating element 304. The fixing plate 302 is disposed on the top of the base plate 301, and the clamping plate 303 is installed on the top of the fixing plate 302. The heating element 304 is disposed at the end of the clamping plate 303. The clamping plate 303 and the base 401 form a locking structure through the clamping groove 402, and the base 401 and the heating element 304 are tightly fitted together. With this setting, it has a heating function, controls temperature changes, and then detects the viscosity of water-based coatings at different temperatures, simulating various actual use environments, making the test results more realistic.

[0029] Working principle: First, remove the sample tray 4 and add the water-based coating to be tested into it. Then, insert the clamping plate 303 into the clamping slot 402 to fix the sample tray 4 in place. Activate the heating element 304 to heat the sample tray 4 until it reaches the required temperature for testing. Next, activate the electric push rod 201 to push the inspection box 202 downwards, causing the gasket 209 to contact the sample tray 4. After holding this position for a certain period, activate the electric push rod 201 again to retract the inspection box 202 upwards. The water-based coating adheres to the gasket 209, causing the movable rod 204 to slide downwards inside the slide groove 203, exposing the scale 206. After the inspection box 202 rises to a certain height, the coating viscosity becomes insufficient, and the spring 205 retracts the movable rod 204 through elastic force, resetting it for the next test.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
