Description

Technical Field

[0001] This utility model relates to the field of viscosity testing technology, and in particular to a water-based paint viscosity testing device. Background Technology

[0002] Viscosity testing of water-based paints is a key step in evaluating the fluidity and viscosity of the paint, which directly affects coating performance, application results and final coating quality. Most of these tests are conducted using a rotational viscometer.

[0003] A rotational viscometer for testing environmentally friendly water-based anti-corrosion coatings, disclosed in Chinese Patent Publication No. CN221465203U, facilitates the installation and replacement of the testing rotor through the design of a locking block, groove, and slot system. However, according to related technologies and existing technologies, traditional rotational viscometers rely on manual alignment during testing, which can easily lead to misalignment between the container center and the testing axis. This causes the probe measurement area to deviate from the uniform sample area (such as the boundary effect area near the container wall), directly affecting the representativeness and accuracy of the test data. Furthermore, the lack of container fixation means that the rotation and agitation of the water-based paint during testing can cause container shaking or even displacement, disrupting the stability of the measurement environment and further exacerbating data fluctuations, making it difficult to meet the requirements for high-precision testing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a water-based paint viscosity testing device.

[0013] This water-based paint viscosity testing device, through the setting of clamping and locking components, converts circumferential motion into radial thrust by utilizing the cooperation of the control groove and guide wheel when the control disc rotates. This automatically centers and clamps the container, ensuring precise alignment between the container center and the rotation axis of the viscosity testing module, improving the representativeness and accuracy of the test data.

[0018] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0019] like Figures 1 to 6As shown, a water-based paint viscosity testing device includes a base 1, a support rod 2 fixedly mounted on one side of the base 1, a movable sleeve 4 vertically slidably mounted on the outside of the support rod 2, a viscosity testing module 3 fixedly mounted on the movable sleeve 4, a clamping assembly 5 for centering and clamping a container on the top of the base 1, and a locking assembly 6 for locking the movable sleeve 4 and the clamping assembly 5 installed inside the support rod 2. The movable sleeve 4 and the support rod 2 have damping, which can maintain the position of the viscosity testing module 3 without external force. In use, a container containing the water-based paint to be tested is placed on the clamping assembly 5, and then the clamping assembly 5 is controlled to center and clamp the container, ensuring that the center of the container corresponds to the rotation axis of the viscosity testing module 3, improving the accuracy of the test. Then, the movable sleeve 4 drives the probe of the viscosity testing module 3 downward into the water-based paint. Finally, the locking assembly 6 is controlled to lock the clamping assembly 5 and the movable sleeve 4, simultaneously locking the viscosity testing module 3 and the clamping assembly 5, ensuring the stability of subsequent tests.

[0020] like Figure 1 and Figure 2 As shown, the clamping assembly 5 includes a clamping seat 51 fixedly mounted on the top of the base 1. A control disk 52 is rotatably mounted on the bottom of the clamping seat 51. Three radially arranged sliding grooves 55 are evenly arranged on the clamping seat 51, and a gripper 53 is slidably mounted in each sliding groove 55. A control groove 54 inclined towards the center of the disk is opened on the control disk 52 corresponding to the position of each gripper 53. The gripper 53 includes a slider 531 slidably mounted in the sliding groove 55. A guide wheel 532 adapted to the control groove 54 is fixedly mounted on the bottom of the slider 531, and a clamping rod 533 is fixedly mounted on the top of the slider 531. A buffer sleeve 53 is sleeved on the outside of the clamping rod 533. 4. A handle 8 is fixedly provided on the outer surface of the control panel 52. The container containing the water-based paint to be tested is placed on the clamp 51. Then, the control panel 52 is rotated by the handle 8. The control groove 54 on the control panel 52 cooperates with the guide wheel 532 to convert the thrust generated by the circumferential movement of the control panel 52 into radial thrust, thereby synchronously pushing the three sliders 531 to drive the gripper 53 to move radially along the slide groove 55 and synchronously approach the center of the clamp 51 to achieve centering and clamping of the container. This ensures that the center of the container is aligned with the rotation axis of the viscosity detection module 3, improving the detection accuracy. A buffer sleeve 534 is fitted on the outside of the clamping rod 533 to avoid damage to the container during clamping.

[0021] like Figures 1 to 6As shown, the locking assembly 6 includes a locking plate 61 movably mounted on one side of the support rod 2. The locking plate 61 is vertically positioned and one side contacts the inner side of the movable sleeve 4. A trigger plate 63 is provided on the side of the locking plate 61 away from the movable sleeve 4. Multiple wedges 62 are fixedly mounted on the side of the locking plate 61 near the trigger plate 63. A groove 64 is provided on the trigger plate 63 corresponding to the position of each wedge 62. A screw 65 that is threadedly engaged with the support rod 2 is rotatably mounted on the top of the trigger plate 63. A locking block 9 is fixedly mounted on the bottom of the locking plate 61. One end of the locking block 9 is in contact with the outer surface of the control panel 52. The wedge 62 has a right-angled trapezoidal cross-section with the inclined surface facing upwards. The inside of the support rod 2 is provided with a movable groove 7 for the vertical sliding of the trigger plate 63; the rotating screw 65 controls the trigger plate 63 to move downward. At this time, the groove 64 on the trigger plate 63 presses against the inclined surface of the wedge block 62, converting the downward thrust into a lateral thrust on the locking plate 61, thereby pushing one side of the locking plate 61 to press against the inner side of the movable sleeve 4, increasing the contact pressure and friction between the two, and locking the position of the movable sleeve 4. At the same time, the locking block 9 at the bottom of the locking plate 61 will press against the outer surface of the control disk 52, limiting its rotation through friction, thereby simultaneously fixing the position of the viscosity detection module 3 and the state of the clamping assembly 5, which is convenient and quick.

[0022] The work process is as follows: S1: As Figure 1 As shown, initially, the movable sleeve 4 is held at the preset height of the support rod 2 by the initial damping, the viscosity detection module 3 is in the initial position, and the three clamping rods 533 are in the open state. At this time, the container containing the water-based paint to be tested is placed in the center of the clamp 51. S2: As Figure 1 and Figure 2 As shown, by rotating the control disk 52 by the handle 8, the control groove 54 on the control disk 52 interacts with the guide wheel 532 at the bottom of the gripper 53, converting the circumferential rotation into radial thrust, causing the three sliders 531 to move synchronously towards the center along the slide groove 55. The clamping rod 533 drives the buffer sleeve 534 to gradually approach and fit against the outer wall of the container until the buffer sleeve 534 tightly wraps the container to achieve centering and clamping, ensuring that the center of the container is precisely aligned with the rotation axis of the viscosity detection module 3, thereby improving the detection accuracy. S3: As Figure 1 As shown, a downward force is manually applied to the movable sleeve 4 to overcome the initial damping and make it slide vertically along the support rod 2, which drives the probe of the viscosity detection module 3 to slowly move down until the probe is completely immersed in the water-based paint in the container. At this time, the force is stopped and the movable sleeve 4 temporarily maintains its current position by relying on the initial damping. S4: As Figure 3 and Figure 4As shown, rotating screw 65 drives trigger plate 63 to slide downward along movable groove 7. The groove 64 on trigger plate 63 presses against the inclined surface of wedge block 62 of locking plate 61, generating a lateral thrust to push locking plate 61 towards movable sleeve 4. The contact pressure between one side of locking plate 61 and the inner side of movable sleeve 4 increases, locking the position of movable sleeve 4 through friction. At the same time, locking block 9 at the bottom of locking plate 61 presses against the outer surface of control disk 52, using friction to limit the rotation of control disk 52, achieving locking in the clamped state, ensuring the stability of container and probe position during detection, and improving detection stability. S5: As Figures 1 to 3 As shown, the viscosity detection module 3 is started, and the probe performs viscosity detection on the water-based paint according to the set parameters. The detection data is transmitted to the control system in real time. After the detection is completed, the viscosity detection module 3 is turned off, the screw 65 is rotated in the opposite direction to release the lock, the movable sleeve 4 is moved up to make the probe separate from the container, the control disk 52 is rotated in the opposite direction to release the clamp 53, the container is removed, and one detection process is completed.

[0023] The viscosity detection module 3 in this application is a well-known technology in this field, therefore its specific structure and working principle are not described in detail.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
