Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of paint detection, and in particular to a paint viscosity detection device. Background Art
[0002] Paint viscosity testing is critical to evaluating paint performance and ensuring construction and film quality. There are various testing methods, such as the Tu-4 cup method to measure low viscosity, judging by the outflow cut-off time; the rotational viscometer method is applicable to various viscosity ranges and is calculated by the rotor resistance torque. The test is affected by temperature, stirring, and placement time, and the conditions must be strictly controlled. Based on the results, it can be judged whether the paint meets the standards. If it does not meet the standards, it can be optimized by adjusting the diluent.
[0003] In the coating industry, the coating-4 cup method is a commonly used means of testing paint viscosity. At present, the traditional manually operated coating-4 cup method has many disadvantages. After adding paint manually, the blockage to the outflow hole needs to be manually removed. This process makes it difficult to ensure the accuracy and consistency of each operation. In terms of recording time, relying on manual observation of the disconnection of the paint outflow line and timing is prone to large errors due to differences in human reaction speed. At the same time, when the operator is testing on site, his walking, breathing and other behaviors will disturb the airflow, causing uncontrollable interference to the paint outflow speed, resulting in deviations in the test results. These problems seriously affect the accuracy and reliability of paint viscosity detection.
[0004] Based on this, a paint viscosity detection device is proposed. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] See also Figures 1 - 5 , the present invention provides a technical solution: A paint viscosity detection device comprises a base 1, a connecting plate 2 is connected to one side of the base 1, the base 1 is used to ensure the stability of the connection plate 2, a clamping block 18 is slidably connected to one side of the connection plate 2, a pushing cylinder 10 is connected to the lower end of the clamping block 18, the pushing cylinder 10 is in a vertical state, the pushing cylinder 10 is connected to one side of the connection plate 2, a moving bar 7 is connected to one side of the clamping block 18, a viscosity cup 14 is connected to the moving bar 7, a rotating shaft 21 is connected to the lower end of the viscosity cup 14, a blocking bar 23 is rotatably connected to the rotating shaft 21, a torsion spring 22 is connected between the blocking bar 23 and the viscosity cup 14, the torsion spring 22 is sleeved on the rotating shaft 21, the blocking bar 23 is driven to deflect by the torsion spring 22, so that one end of the blocking bar 23 can abut against the outflow port of the viscosity cup 14, complete the sealing of the outflow port of the viscosity cup 14, avoid the paint from dripping before the viscosity detection, and ensure that the volume of the paint in the viscosity cup 14 is fixed before each detection; A deflection frame 15 is connected to one side of the moving bar 7, and a transmitting end 16 is connected to the deflection frame 15. The deflection frame 15 is arranged so that the transmitting end 16 can be kept away from the viscosity cup 14 before detection, so as to avoid that part of the paint splashes onto the transmitting end 16 when adding paint into the viscosity cup 14, thereby polluting the detection structure and interfering with the detection accuracy. A connecting frame 4 is connected to the connecting plate 2, and a receiving end 5 is connected to one end of the connecting frame 4. A transmission mechanism for deflecting the blocking strip 23 is connected to one side of the moving bar 7, so that the transmitting end 16 is docked with the receiving end 5, and the timing of the falling of the paint in the viscosity cup 14 is completed. The two operation steps of opening the downstream outlet of the viscosity cup 14 and docking the transmitting end 16 with the receiving end 5 are completed simultaneously. At this time, the pushing cylinder 10 is just extended to the maximum state, and this is the initial timing point of the paint viscosity detection.
[0020] Specifically, Figure 1 and Figure 3 As shown, a vertical rail 6 is connected to one side of the connecting plate 2, and a clamping block 17 is slidably connected to the vertical rail 6. The clamping block 17 is fixedly connected to one side of the clamping block 18. The sliding rail structures on the clamping block 17 and the clamping block 18 are perpendicular to each other, that is, the sliding rail on the clamping block 17 is in the vertical direction, and the sliding rail structure on the clamping block 18 is in the horizontal direction. Through the structure of the clamping block 17 and the clamping block 18, the movable bar 7 can be moved in the horizontal direction as well as in the vertical direction.
[0021] Specifically, Figure 4 As shown, the movable bar 7 is connected with a docking seat 27, the docking seat 27 is connected with an insertion rod 28, the insertion rod 28 is connected with a docking cover 13, the viscosity cup 14 is clamped between the docking seat 27 and the docking cover 13, and two insertion rods 28 are provided. When the docking cover 13 and the docking seat 27 need to be docked and assembled, it is only necessary to clamp the docking cover 13 on the insertion rod 28, wherein the docking cover 13 is provided with a circular hole corresponding to the insertion rod 28. After the above structure is assembled, the viscosity cup 14 can be placed between the docking seat 27 and the docking cover 13, wherein the limiting ring structure provided on the viscosity cup 14 can also prevent the docking seat 27 from being separated from the docking cover 13, further stabilize the placement stability of the viscosity cup 14, and improve the stability of the movement of the viscosity cup 14 structure before the detection starts.
[0022] Specifically, Figure 3 As shown, a baffle 20 is connected to the lower end of the viscosity cup 14, and one side of the blocking strip 23 abuts against the baffle 20. The baffle 20 is used to limit the deflection of the blocking strip 23, so that when the blocking strip 23 deflects to one side and abuts against the baffle 20, the blocking strip 23 can just seal the flow outlet at the lower end of the viscosity cup 14.
[0023] Specifically, Figure 1As shown, a connecting frame 11 is connected to one side of the connecting plate 2, and a receiving cup 12 is connected to the connecting frame 11. The receiving cup 12 is arranged below the viscosity cup 14. When the paint in the viscosity cup 14 flows out, the receiving cup 12 is arranged just below the viscosity cup 14. The flowing paint is collected by the receiving cup 12 to prevent the flowing paint from polluting the detection environment. The receiving cup 12 and the connecting frame 11 are detachable structures, and the receiving cup 12 can be easily removed from the connecting frame 11 to be cleaned.
[0024] Specifically, Figure 1 As shown, a cylinder frame 9 is connected to one side of the connecting plate 2, and a pushing cylinder 10 is fixedly connected to the cylinder frame 9. The pushing cylinder 10 is connected with the cylinder frame 9 to ensure the firmness of the structure of the pushing cylinder 10.
[0025] Specifically, Figure 1 and Figure 4 As shown, the transmission mechanism includes a slide tube 8, a V-shaped groove 3 is provided on the connecting plate 2, the slide tube 8 is slidably connected to the V-shaped groove 3, the movement of the moving bar 7 is limited by the slide tube 8, and the movement of the slide tube 8 is limited by the V-shaped groove 3, the deflection frame 15 is rotatably connected to the slide tube 8, one end of the deflection frame 15 is connected to the shaft 1 25, the shaft 1 25 is rotatably connected to the traction bar 26, the clamping block 2 18 is connected to the shaft 2 30, and the other end of the traction bar 26 is rotatably connected to the shaft 2 30. When the moving bar 7 slides on the clamping block 2 18, the distance between the shaft 1 25 and the shaft 2 30 changes, so that the traction bar 26 can be used to push the deflection frame 15 to deflect, so that the transmitting end 16 connected to one end of the deflection frame 15 is deflected to a state of docking with the receiving end 5; A toggle frame 19 is connected to one side of the clamping block 18. When the moving bar 7 slides on the clamping block 18, the toggle frame 19 can approach or move away from one end of the blocking bar 23. When the toggle frame 19 approaches the blocking bar 23, the toggle frame 19 can be used to toggle the blocking bar 23 to deflect it, so that one end of the blocking bar 23 moves away from the baffle 20. At this time, the paint outflow outlet at the lower end of the viscosity cup 14 is opened.
[0026] Specifically, Figure 4 As shown, a deflection rod 29 is connected to one side of the deflection frame 15, and one end of the deflection rod 29 is connected to a limiting plate 24. The deflection rod 29 is rotatably connected in the sliding tube 8, and the sliding tube 8 is used to limit the deflection rod 29 structure. The limiting plate 24 structure provided therein can avoid separation between the deflection rod 29 and the sliding tube 8, thereby ensuring the rotation stability of the deflection rod 29.
[0027] In summary, the paint viscosity detection device provided in this embodiment can, when it is necessary to detect the viscosity of the paint, inject the paint to be tested into the viscosity cup 14. After the paint is added, it is necessary to scrape off the excess paint in the viscosity cup 14, and accurately control the amount of paint added to be tested to be 100 ml. Then the operator can move to the remote operation detection device to complete the viscosity detection of the paint, avoid airflow disturbance caused by people walking, breathing, etc., and ensure that the paint outflow speed is not affected by external interference.
[0028] During the inspection, the inspector controls the extension of the push cylinder 10, and uses the push cylinder 10 to push the clamping block 2 18 to rise in height. The moving bar 7 slidably connected to the clamping block 2 18 rises in height synchronously. At this time, the slide tube 8 connected to one side of the moving bar 7 will slide in the V-shaped groove 3. When the slide tube 8 slides in the first section of the V-shaped groove 3, the slide tube 8 rises vertically. When the slide tube 8 slides in the second section of the V-shaped groove 3, the slide tube 8 moves obliquely upward, and the slide tube 8 moves horizontally toward the vertical rail 6. The moving bar 7 slides on the clamping block 2 18, and the toggle frame 19 moves toward one end of the blocking bar 23. The toggle frame 19 drives the blocking bar 23 to deflect. At this time, the outflow port below the viscosity cup 14 is opened, and the traction bar 26 can push the deflected The rotating frame 15 is deflected. At this time, the deflection frame 15 is in a vertical state when it is opened below the outflow port. At this time, the transmitting end 16 and the receiving end 5 are arranged opposite to each other. When the rays emitted by the transmitting end 16 enter the paint medium, the rays will be refracted, so that the receiving end 5 cannot receive the rays. When the paint outflow line in the viscosity cup 14 is disconnected, the receiving end 5 can receive the timing signal to ensure that the outflow time can be recorded in the first time. Compared with manual timing, the timing error can be greatly reduced and the viscosity detection accuracy can be improved. The automatic paint viscosity detection device can avoid manual interference, make the detection result more accurate and reliable, and provide more valuable reference data for the paint production and use links.
