[0030] Reference Figure 1 and Figure 2 According to the present invention, a paint viscosity detection device includes a box 100, a holding dish 200, and a detection mechanism. The box 100 is provided with an inner cavity 101. The side of the box 100 is provided with an opening 102 connected to the inner cavity 101. The bottom wall of the inner cavity 101 is provided with a groove 103. The holding dish 200 is placed in the groove 103. The inner walls of the groove 103 on both sides are provided with a fixing structure. The fixing structure includes a spring 110 and a clamp 120. One end of the spring 110 is fixed to the inner wall of the groove 103. The other end of the spring 110 is fixedly connected to the clamp 120, and the clamp 120 is adapted to the shape of the holding dish 200. The spring 110 forces the clamp 120 to press the outer wall of the holding dish 200; the detection mechanism is arranged in the inner cavity 101, and the detection mechanism includes a viscometer 310 and a first driving structure. The viscometer 310 is provided with a rotating shaft 311, and the rotating shaft 311 is downward and located directly above the holding dish 200. The first driving structure is installed on the box 100, and the first driving structure is connected to the viscometer 310 and drives the viscometer 310 to move up and down.

[0031] Specifically, when using the paint viscosity detection device provided by the embodiment of the present invention, the experimenter places the paint-filled container 200 through the opening 102 into the groove 103 and places it between the two clamps 120. By utilizing the elastic action of the spring 110, the clamps 120 are forced to press against the outer wall of the container 200. Because the clamps 120 are adapted to the shape of the container 200, the two clamps 120 can hold the container 200 tightly, thereby preventing the container 200 from shaking during the stirring process, ensuring that the stirring position of the viscometer 310 does not shift, and ensuring the accuracy of the test results. After the container 200 is placed, the viscometer 310 is driven downward by the first drive structure so that the rotating shaft 311 is inserted into the paint in the container 200. The first drive structure can adjust the depth of the rotating shaft 311 inserted into the paint, thereby enabling the viscosity of the paint at different positions to be detected.

[0032] Further, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, guide posts 130 are provided on the inner walls on both sides of the groove 103 . The guide posts 130 extend in the horizontal direction. The guide posts 130 correspond to the springs 110 one by one, and the springs 110 are sleeved on the guide posts 130 .

[0033] It is understandable that the spring 110 may deform during long-term use, causing the spring 110 to deviate in height when extended, thereby preventing the clamp 120 from pressing the container 200. To address the above technical issues, the present embodiment of the utility model provides a guide post 130 in the spring 110 to limit the extension direction of the spring 110 and ensure that the clamp 120 can press the container 200.

[0034] Further, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, a non-slip pad 140 is provided on the bottom wall of the groove 103 to reduce the friction between the holding dish 200 and the bottom wall of the groove 103, further preventing the holding dish 200 from sliding.

[0035] Further, refer to Figure 1 According to some embodiments of the present invention, the first driving structure includes an electric push rod 320, one end of the electric push rod 320 is fixed to the top wall of the inner cavity 101, and the other end of the electric push rod 320 is provided with a push rod 321, which is downward and connected to the viscometer 310 through the connecting plate 330, so that the viscometer 310 is driven up and down by the electric push rod 320, so that the rotating shaft 311 of the viscometer 310 can be inserted into the holding dish 200 to stir the paint.

[0036] Further, refer to Figure 1 According to some embodiments of the present invention, the first driving structure further includes a guide plate 340, and vertical first sliding grooves 104 are provided on the inner walls on opposite sides of the inner cavity 101. The opposite sides of the guide plate 340 are respectively slidably connected to the two first sliding grooves 104, and the end of the push rod 321 is fixedly connected to the upper end surface of the guide plate 340, and the viscometer 310 is connected to the lower end surface of the guide plate 340 through the connecting plate 330.

[0037] Specifically, the two first sliding grooves 104 can guide the guide plate 340 to ensure that the viscometer 310 moves correctly.

[0038] Further, refer to Figure 1 According to some embodiments of the present invention, the detection mechanism also includes a CCD camera 350, a second drive structure and a control system. The CCD camera 350 is installed on the lower end surface of the connecting plate 330 and faces the groove 103. The second drive structure is installed on the lower end surface of the guide plate 340. The second drive structure is connected to the connecting plate 330 and can drive the connecting plate 330 to move in the horizontal direction. The CCD camera 350, the electric push rod 320 and the second drive structure are all electrically connected to the control system.

[0039] It can be understood that the viscometer 310 is driven to perform lateral horizontal movement by the second driving structure, so that the lateral position of the viscometer 310 can be adjusted to facilitate the detection of the viscosity of the paint at different positions in the holding dish 200, thereby reducing the detection error. Since it is inconvenient for the experimenter to observe and operate inside the box 100, a CCD camera 350 is provided to detect the specific position of the holding dish 200 in real time, so that the experimenter can control the first driving structure and the second driving structure through the control system from the outside to control the viscometer 310 to move to the desired detection position and perform viscosity detection of the paint at the corresponding position, thereby improving the degree of automation.

[0040] It should be noted that the principle of the CCD camera 350 is to capture images and perform image analysis on a computer to compare sample coordinates. In the embodiment of the present invention, due to different tension levels of the two springs 110 or other reasons, the container 200 may not be in the middle of the groove 103. By presetting the coordinates of the middle position of the groove 103 in the control system, when the viscometer 310 needs to be moved, the CCD camera 350 captures an image of the groove 103, and the control system performs image analysis. The actual coordinates of the container 200 in the groove 103 in the image are compared and analyzed, and the movement path of the viscometer 310 is calculated. This allows the experimenter to control the first and second drive structures through the control system to drive the viscometer 310 to the designated detection position, thereby ensuring the accuracy of the detection results.

[0041] Further, refer to Figure 1 According to some embodiments of the present invention, the second driving structure includes a screw motor 360 and a nut 370. The screw motor 360 is installed on the lower end surface of the guide plate 340. The screw motor 360 is provided with a transmission rod 361. The transmission rod 361 extends in the horizontal direction. The nut 370 is sleeved on the transmission rod 361. The lower end surface of the guide plate 340 is provided with a second slide groove 341. The upper end surface of the nut 370 can be slidably connected to the second slide groove 341. The lower end surface of the nut 370 is fixedly connected to the connecting plate 330.

[0042] Specifically, the screw motor 360 can convert the rotational motion of the transmission rod 361 into the linear motion of the nut 370 , thereby driving the connecting plate 330 to move laterally, and further driving the viscometer 310 to move laterally to adjust the lateral position of the viscometer 310 .

[0043] Further, refer to Figure 1 According to some embodiments of the present invention, the outer wall of the box 100 is hinged with a door panel 140 to open or close the opening 102, thereby preventing foreign matter from entering the inner cavity 101 during the detection process, thereby ensuring the smooth progress of the detection work.

[0044] Further, refer to Figure 1 According to some embodiments of the present invention, the paint viscosity detection device further includes a heating mechanism, which includes a fan 410, a heating wire 420 and a temperature sensor 430. The fan 410 is installed on the inner wall of the inner cavity 101 and faces the opening 102. The heating wire 420 is arranged on the side of the fan 410 facing the opening 102. The temperature sensor 430 is installed on the top wall of the inner cavity 101. The fan 410, the heating wire 420 and the temperature sensor 430 are all electrically connected to the control system.

[0045] Specifically, in the present invention, the temperature inside the box 100 can be easily adjusted by using the fan 410 and the heating wire 420, and the temperature is monitored in real time by the temperature sensor 430. The box 100 seals and insulates its interior. When the temperature needs to be increased, the control system simultaneously starts the fan 410 and the heating wire 420 to increase the ambient temperature of the paint. When the temperature needs to be lowered, the control system only starts the fan 410 to cool the box 100, and when necessary, the door panel 140 can be opened for ventilation to improve the heat dissipation efficiency, thereby reducing the ambient temperature of the paint in the holding dish 200, and then the viscometer 310 is used to detect the viscosity of the paint, so that the viscosity of the paint in each temperature range can be detected.

[0046] Further, refer to Figure 1 According to some embodiments of the present invention, a foot pad 150 is provided at the bottom of the box 100 to provide support.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
