Description

Technical Field

[0001] The present invention relates to the technical field of coating fluidity detection devices, and particularly to a polyurethane waterproof coating fluidity detection device. Background Art

[0002] Polyurethane waterproof coating is a one-component waterproof coating made of prepolymers containing isocyanate groups formed by addition polymerization of isocyanates, polyethers, etc., and formulated with other additives; the fluidity of polyurethane waterproof coating is one of its important properties, usually manifested as low viscosity during melt flow, providing sufficient leveling time for powder coatings, so the leveling property of the coating film is excellent. This characteristic enables the polyurethane waterproof coating to be more easily applied evenly during construction to form a flat waterproof layer; and the polyurethane waterproof coating fluidity detection device is mainly used to evaluate the fluidity of the coating during construction, which is crucial for ensuring the construction performance of the coating and the final waterproof effect.

[0003] According to the polyurethane waterproof coating fluidity detection device with the publication number CN118896879B, this patent includes a bearing box, a flow channel is fixedly installed above the bearing box, an axial flow fan blade is rotatably installed inside the flow channel, and a funnel is fixedly installed above the flow channel; an automatic detection mechanism, the automatic detection mechanism is fixedly installed at the bearing of the axial flow fan blade, and is used to automatically measure the time required for the waterproof coating to completely flow out. By setting the automatic detection mechanism, during detection, the impact force generated by the flow of the waterproof coating will drive the axial flow fan blade to rotate, and then the liquid storage chamber and the centrifugal sleeve will rotate. Under the action of centrifugal force, the piston block slides inside the centrifugal sleeve, so that the first conductive sheet contacts the second conductive sheet, and the timer starts timing, automatically measuring the time required for the waterproof coating to completely flow out, and detecting its fluidity according to the outflow time of the waterproof coating.

[0004] However, during the use of the above patent, the storage tank of the waterproof coating is cleaned by scraping with a scraping rod. This cleaning method is difficult to reach the tiny gaps or depressions in the tank body, resulting in the existence of residual waterproof coating in these areas, making it easy to be interfered by residues or dirt during the detection process, and it is difficult to realize the integration of cleaning and detection, which will lead to low detection efficiency, affected accuracy of detection results, and require more operation steps and higher operation skill requirements for the staff to complete the detection work of the waterproof coating, thus affecting the accuracy and precision of the detection results.

There are two fixing plates 802 respectively located on both sides of the bottom of the guiding frame 801.;

[0032] During specific implementation, after a single test of the fluidity of the polyurethane waterproof coating is completed during the use of the fluidity detection device for the polyurethane waterproof coating, first start the electric push rod 4. Since the output end of the electric push rod 4 is connected to the servo motor 5, the extension of the electric push rod 4 will drive the servo motor 5 to move upward. Then, the upward movement of the servo motor 5 will drive the transmission column 601 to move upward until the top end of the transmission column 601 is docked with the limit seat 602, and at this time, the fixed gear 603 will also move upward and disconnect from the transmission gear 702. Then start the servo motor 5 to rotate and drive the transmission column 601 to rotate. After that, the rotation of the transmission column 601 drives the threaded column 604 to rotate through the limit seat 602. Since the threaded column 604 is threadedly connected to the threaded barrel 605, the rotation of the threaded column 604 causes the threaded barrel 605 to move upward. Refer to Figure 2 and Figure 5 , and since the bottom of the rotating frame 608 is connected to the support rod 613, at this time, the support rod 613 slides along the support column 614, thereby guiding the up and down movement of the rotating frame 608. Since the bottom of the threaded barrel 605 is connected to the guide rod 606 and the top is connected to the rotating frame 608, the movement of the threaded barrel 605 will drive the guide rod 606 and the rotating frame 608 to move together. And since the rotating frame 608 is connected to the coating barrel 609, the movement of the rotating frame 608 will drive the coating barrel 609 to move together. At this time, the bottom of the support column 614 will rotate along the track 615, and the friction is reduced by the ball. Therefore, the support rod 613 and the support column 614 will not hinder the rotating frame 608 from driving the coating barrel 609 to rotate;

[0033] Since the outer wall of the fixed cylinder 607 is provided with a first straight groove 610, a rotating groove 611 and a second straight groove 612, when the threaded cylinder 605 moves upward, the guide rod 606 first moves upward along the first straight groove 610 until the guide rod 606 reaches the top of the first straight groove 610. At this time, the paint cylinder 609 also moves upward, and then moves out from the inside of the fixed tank 616 and the cleaning tank 617 respectively. Then, when the threaded cylinder 605 continues to move upward, the guide rod 606 will start to rotate along the rotating groove 611, and then generate a thrust on the threaded cylinder 605 to make it move upward and rotate at the same time until the guide rod 606 reaches the top of the rotating groove 611. At this time, the threaded cylinder 605 drives the rotating frame 608 to rotate counterclockwise by 90 degrees. Then, the rotation of the rotating frame 608 makes the paint cylinder 609 also rotate counterclockwise by 90 degrees. As a result, the paint cylinder 609 moved out from the fixed tank 616 will move above the cleaning tank 617, and the paint cylinder 609 moved out from the cleaning tank 617 will move above the fixed tank 616. After that, the servo motor 5 is started to make the threaded cylinder 605 move downward. At this time, the guide rod 606 will move downward along the second straight groove 612, and then make the rotating frame 608 drive the paint cylinder 609 to move downward until the paint cylinder 609 moves into the fixed tank 616 and the cleaning tank 617 respectively. At this time, the water flow in the cleaning tank 617 will clean the entering paint cylinder 609. Then, the cleaning method of water washing can be used to clean the tiny gaps or depressions of the paint cylinder 609, prevent the existence of paint residues in these areas from affecting the accuracy of the monitoring results, and while cleaning the used paint cylinder 609, the waterproof paint can be poured into the paint cylinder 609 inside the fixed tank 616, and then introduced into the measuring cylinder 619 through the output pipeline 618. Therefore, while carrying out the cleaning work, the fluidity of the waterproof paint can be continuously detected. And because two groups of fixed tanks 616 and cleaning tanks 617 are provided respectively, the fluidity of two different types of waterproof paints can be detected at the same time, or a comparative experiment can be carried out to improve the efficiency;

[0034] After the fluidity detection of the waterproof coating this time is completed, start the servo motor 5 to move the threaded cylinder 605 upward. Then, as the threaded cylinder 605 moves upward, the guide rod 606 will move upward along the second straight groove 612 to its top, and then the rotating frame 608 will drive the coating cylinder 609 to move upward linearly to the designated position. Then start the servo motor 5 to move the threaded cylinder 605 downward. At this time, the guide rod 606 will reach the first straight groove 610 along the rotating groove 611, and then the threaded cylinder 605 will drive the rotating frame 608 to rotate clockwise by 90 degrees until the cleaned coating cylinder 609 is located above the fixed tank 616 and the used coating cylinder 609 is located above the cleaning tank 617. After that, when the threaded cylinder 605 moves downward, the guide rod 606 will move downward along the first straight groove 610, and then the cleaned coating cylinder 609 will move downward into the fixed tank 616, and the used coating cylinder 609 will move downward into the cleaning tank 617 for cleaning. Then, the fluidity of the waterproof coating will continue to be detected through the cleaned coating cylinder 609. Thus, during the coating detection process by the cleaning mechanism 6, the previously used coating cylinder 609 can be cleaned, and finally, the integration of cleaning and detection is achieved to improve the detection efficiency;

[0035] Before the fluidity detection of the waterproof coating is carried out, first start the electric push rod 4 to contract and drive the servo motor 5 to move downward. As the servo motor 5 moves downward, it will drive the transmission column 601 and the fixed gear 603 to move downward together until the transmission column 601 is disconnected from the limit seat 602 and the fixed gear 603 is in contact with the transmission gear 702 and in a meshing state. Then start the servo motor 5 to drive the fixed gear 603 to rotate through the transmission column 601. Since the fixed gear 603 is meshed with the transmission gear 702, the rotation of the fixed gear 603 will drive the transmission gear 702 to rotate. Then the rotation of the transmission gear 702 will drive the rotating column 701 to rotate. And because the rotating column 701 is connected to the first synchronous wheel 703, the rotation of the rotating column 701 will drive the first synchronous wheel 703 to rotate together. And because the first synchronous wheel 703 is connected to the second synchronous wheel 704 through a synchronous belt, the rotation of the first synchronous wheel 703 will drive the second synchronous wheel 704 to rotate together. And because the second synchronous wheel 704 is respectively connected to the stirring frame 705 and the cleaning frame 706 inside, the rotation of the second synchronous wheel 704 will drive the stirring frame 705 and the cleaning frame 706 to rotate together;

[0036] At this time, as the stirring frame 705 rotates, the paint in the paint cylinder 609 keeps flowing, thereby keeping the paint in a stable flowing state, maintaining the uniformity of the paint, preventing it from stratifying or caking and affecting the test results, and ensuring that the state of the paint during the test is consistent with that in actual application, so as to improve the accuracy and reliability of the test. At the same time, the cleaning frame 706 also makes the water flow in the cleaning tank 617 rotate continuously. At this time, the rotation of the water flow in the cleaning tank 617 can form a vortex, and this vortex can penetrate into the corners and inaccessible parts of the paint cylinder 609, thus avoiding the appearance of cleaning dead corners. Since the cleaning frame 706 is connected with a cleaning sponge 708 through a clamping seat 707, the cleaning sponge 708 will rotate together when the cleaning frame 706 rotates, and then it will rub against the inner wall of the paint cylinder 609 to assist in cleaning the paint involved. At the same time, the dynamic cleaning method can make the cleaning agent more evenly distributed in the cleaning tank 617, improve the utilization rate and cleaning effect of the cleaning agent, thus accelerating the cleaning process and shortening the cleaning time. And when the cleaning of the paint cylinder 609 in the cleaning tank 617 is completed, the paint in the paint cylinder 609 in the fixed tank 616 has not been completely discharged. At this time, the water flow in the cleaning tank 617 is discharged, and the water in the cleaning sponge 708 also flows out at the same time. Then the cleaning sponge 708 continues to rub against the inner wall of the paint cylinder 609 in the cleaning tank 617, and then absorbs the water droplets remaining on the inner wall of the cleaning tank 617, preventing a large amount of water droplets from remaining on the inner wall of the paint cylinder 609 and affecting the test. Therefore, the cleaning quality, efficiency and test accuracy can be improved through the stirring mechanism 7;

[0037] And when the cleaning mechanism 6 works, it will drive the auxiliary mechanism 8 to work together. Since the top of the rotating frame 608 is connected with the guiding frame 801, when the rotating frame 608 rotates 90 degrees, it will drive the guiding frame 801 to rotate together. Then the guiding frame 801 rotates and contacts the fixed plate 802 to generate a thrust on it. Since the fixed plate 802 is connected with the rotating table 803, when the fixed plate 802 moves due to the thrust, it will drive the rotating table 803 to move together, so that the rotating table 803 rotates around the center line of the base 1. And at this time, the rolling ball 804 rolls along the base 1, and then reduces the friction to assist the rotating table 803 to rotate. After that, the rotation of the rotating table 803 will drive the measuring cylinder 619 to rotate together, so that the used measuring cylinder 619 below the fixed tank 616 is moved away, which is convenient for the staff to take it away. At the same time, a new measuring cylinder 619 also moves to below the fixed tank 616 to wait for the next test work, and finally it is convenient for the staff to take away the used measuring cylinder 619.

[0038] In summary, when the polyurethane waterproof coating fluidity detection device is in use, first place the workbench 2 at a designated position in the laboratory, then pour the polyurethane waterproof coating into the coating cylinder 609, and then pour the polyurethane waterproof coating into the measuring cylinder 619 through the output pipeline 618. At this time, the timer 3 automatically measures the time required for the waterproof coating to completely flow out, and then detects its fluidity according to the outflow time of the waterproof coating. This is the prior art and will not be elaborated here. The cleaned coating cylinder 609 enters the fixed tank 616 through the cleaning mechanism 6 to continue working, and the used coating cylinder 609 enters the cleaning tank 617 for water washing, and then the tiny gaps or depressions of the coating cylinder 609 are cleaned to prevent coating residues from affecting the accuracy of the monitoring results. Moreover, the coating cylinder 609 can be cleaned during the detection process to improve the detection efficiency.
