Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a rotary viscometer for testing curing agents. Background Technology

[0002] The rotary viscometer for testing curing agents is driven by a motor to rotate a scaled disk stably, which in turn drives a rotor to rotate via a hairspring and a shaft. When the rotor is not subject to resistance in the liquid, the hairspring, pointer, and scale rotate at the same speed, and the pointer indicates "0". If the rotor is subject to viscous resistance of the liquid, the hairspring generates torque that balances the resistance. The reading indicated by the pointer multiplied by a specific coefficient is the viscosity of the liquid.

[0003] A search revealed Chinese patent publication number CN116539480B, which describes a rotational viscometer with an air-bearing bearing. The viscometer includes a base with four horizontal adjustment screws at the bottom. A fixing tube is fixedly connected to the top of the base, and a detection component is located on one side of the fixing tube. An electric lifting mechanism for adjusting the height of the detection component is located inside the fixing tube. A liquid storage cup is located below the detection component, and a positioning block is fixedly connected to the bottom of the liquid storage cup. This invention, by incorporating a detection component and utilizing an air-bearing bearing, reduces the mechanical friction generated by the rotating shaft during the use of the detection component, effectively avoiding detection errors caused by mechanical friction and significantly improving the accuracy of the rotational viscometer's test results. Furthermore, the inclusion of an anti-splash component prevents liquid from splashing from the liquid storage cup onto the base or other areas during the testing process.

[0004] However, in actual use, although the above device can effectively prevent the sample from splashing to the outside due to agitation during testing, when the tested item is a curing agent, due to the easy curing characteristic of the curing agent, it can easily solidify on the viscometer if not cleaned in time, causing loss. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rotary viscometer for testing curing agents, aiming to solve the problem of cumbersome cleaning of curing agents when testing their viscosity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary viscometer for testing curing agents, comprising a bracket, a first motor fixedly connected to the front side of the bracket, a detection disk fixedly connected to the bottom of the first motor, a connecting rod fixedly installed at the output end of the first motor, a rotor threadedly connected to the bottom of the connecting rod, a splash guard at the bottom of the detection disk, a cleaning cup at the bottom of the splash guard, a component box fixedly connected to the bottom of the inner wall of the cleaning cup, two second motors fixedly connected to the bottom of the inner wall of the component box, linkage components fixedly installed at the output ends of the two second motors, three cleaning brushes fixedly connected to the top of the two linkage components, cylinders fixedly connected to opposite sides of the two second motors, a water pump fixedly connected to the bottom of the component box, water spray pipes fixedly connected to both output ends of the water pump, and a rotating shaft assembly installed at the bottom of the detection disk.

[0007] The above technical solution involves testing the viscosity of the curing agent, then loading it into a cleaning cup. With the cleaning liquid sprayed by the water pump and the cleaning brush driven by the second motor, the connecting rod and rotor are thoroughly cleaned. This prevents the curing agent from solidifying on the connecting rod and rotor due to insufficient cleaning, making them difficult to clean.

[0008] As a further description of the above technical solution:

[0009] The rotating shaft assembly includes a connecting block, a bearing is fixedly connected to the bottom of the inner wall of the connecting block, and a uniformly distributed groove is opened on the top of the bearing. A laser tachometer is fixedly connected to the rear side of the inner wall of the connecting block, and two oil cans are fixedly connected to the front side of the laser tachometer. An oil supply pipe is fixedly connected between the two oil cans and the groove.

[0010] Through the above technical solution:

[0011] The rotation of the connecting rod is detected by a laser tachometer. When the rotation speed slows down, the bearings are lubricated by controlling two oil cans to restore the bearings to a smooth rotation speed and prevent the test results from being affected by bearing aging.

[0012] As a further description of the above technical solution:

[0013] The outer surface of the connecting block is provided with a sliding groove, and the splash cover fits tightly with the sliding groove.

[0014] Through the above technical solution:

[0015] The sliding groove on the outside of the connecting block fits into the inside of the splash cover, allowing the splash cover to be quickly installed by rotating and engaging during testing, reducing preparation time.

[0016] As a further description of the above technical solution:

[0017] The cleaning brush is in close contact with the rotor and connecting rod, and the cleaning brush rotates under the drive of the second motor.

[0018] Through the above technical solution:

[0019] Driven by the second motor and controlled by the linkage, multiple cleaning brushes rotate during cleaning to thoroughly clean the rotor and connecting rod, preventing the hardener from sticking to them.

[0020] As a further description of the above technical solution:

[0021] The cylinder is fixedly connected to the component box, and the cylinder is activated to push the cleaning brush to move.

[0022] Through the above technical solution:

[0023] The cylinder's activation and deactivation drive the two secondary motors and two sets of cleaning brushes to open and close, facilitating installation, disassembly, and thorough cleaning.

[0024] As a further description of the above technical solution:

[0025] The bottom of the connecting rod is successively connected to the detection disk, the connecting block and the bearing, and the connecting rod rotates under the drive of the first motor.

[0026] Through the above technical solution:

[0027] The connecting rod is driven by the first motor and has a rotor at the bottom. When it rotates, its rotation data and the potential energy of the rotor rotating in the curing agent are detected by the detection disk, and the viscosity of the curing agent is analyzed.

[0028] As a further description of the above technical solution:

[0029] The bottom of the two water spray pipes is fixedly connected to the top of the component box, and the two water spray pipes spray water into the middle of the cleaning cup.

[0030] Through the above technical solution:

[0031] While the cleaning brush is cleaning, the hardener cleaning solution is sprayed onto the rotor in the middle through two water spray pipes to dilute and dissolve it, preventing the hardener from being too sticky and difficult to clean.

[0032] As a further description of the above technical solution:

[0033] Magnets are provided on the top of the cleaning cup and the top of the inner wall of the splash guard, and the cleaning cup and the splash guard are tightly fitted together.

[0034] Through the above technical solution:

[0035] The attraction between the two sets of magnets makes it easy to install the cleaning cup during cleaning, saving installation time and enabling timely and rapid cleaning, thus preventing the hardener from solidifying on the rotor.

[0036] This utility model has the following beneficial effects:

[0037] 1. In this utility model, by setting a splash-proof cover at the bottom of the test plate, the curing agent is prevented from splashing to the outside during the testing of the curing agent. By installing a cleaning cup at the bottom of the splash-proof cover, a water pump sprays out the curing agent cleaning liquid, and a second motor drives multiple cleaning brushes to rotate, so as to clean the connecting rod and rotor in time, thus solving the problem of troublesome cleaning of the curing agent when testing the viscosity of the curing agent.

[0038] 2. In this utility model, by setting a laser tachometer on the top of the bearing, when the first motor drives the connecting rod to rotate, the laser tachometer performs optical monitoring of the connecting rod's rotation speed. When the connecting rod's rotation speed is lower than the set value, the laser tachometer controls two oil cans to supply oil to the bearing through the oil supply pipe to lubricate it, preventing bearing aging and solving the problem that the detection effect is affected by bearing aging after long-term use of the viscometer.

Detailed Implementation

[0047] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a rotary viscometer for testing curing agents, comprising a bracket 1, a first motor 2 fixedly connected to the front side of the bracket 1, a detection disk 3 fixedly connected to the bottom of the first motor 2, a connecting rod 14 fixedly provided at the output end of the first motor 2, a rotor 15 threadedly connected to the bottom of the connecting rod 14, a splash guard 5 provided at the bottom of the detection disk 3, a cleaning cup 6 provided at the bottom of the splash guard 5, a component box 13 fixedly connected to the bottom of the inner wall of the cleaning cup 6, two second motors 10 fixedly connected to the bottom of the inner wall of the component box 13, a linkage 9 fixedly provided at the output end of each of the two second motors 10, three cleaning brushes 7 fixedly connected to the top of each of the two linkage 9, cylinders 11 fixedly connected to opposite sides of each of the two second motors 10, a water pump 12 fixedly connected to the bottom of the component box 13, a water spray pipe 8 fixedly connected to both output ends of the water pump 12, and a rotating shaft assembly 4 provided at the bottom of the detection disk 3;

[0049] Specifically, when testing the viscosity of the curing agent, after installing the splash guard 5, the monitoring part is lowered by adjusting the bracket 1 so that the splash guard 5 completely covers the container holding the curing agent. Then, the first motor 2 is started for testing. After the test is completed, the adjusting bracket 1 is moved up, and the cleaning cup 6 is installed at the bottom of the splash guard 5. The two second motors 10 are started to cause the cleaning brushes 7 on both sides to squeeze the connecting rod 14 and rotor 15 in the middle. The water pump 12 is started to spray the cleaning liquid from the water spray pipes 8 on both sides to the middle. The second motor 10 drives the linkage 9 to make the individual cleaning brush 7 rotate, thereby cleaning the connecting rod 14 and rotor 15, solving the problem of troublesome cleaning of the curing agent when testing the viscosity of the curing agent.

[0050] Reference Figure 5 and Figure 6 The rotating shaft assembly 4 includes a connecting block 401. A bearing 402 is fixedly connected to the bottom of the inner wall of the connecting block 401. The top of the bearing 402 has evenly distributed grooves 403. A laser tachometer 406 is fixedly connected to the rear side of the inner wall of the connecting block 401. Two oil cans 404 are fixedly connected to the front side of the laser tachometer 406. An oil supply pipe 405 is fixedly connected between the two oil cans 404 and the grooves 403.

[0051] Specifically, when the connecting rod 14 is driven to rotate by the first motor 2, its rotational speed is adjusted to a fixed speed by the first motor 2. During the rotation of the connecting rod 14, the laser tachometer 406 monitors the rotational speed of the connecting rod 14 in real time. If the rotational speed of the connecting rod 14 becomes slow, the laser tachometer 406 issues an abnormal alarm and activates the two oil reservoirs 404. Oil is supplied to the bearing 402 for lubrication through the oil pipe 405 and the groove 403. When the first motor 2 is restarted and the rotational speed of the connecting rod 14 returns to normal, the laser tachometer 406 no longer issues an alarm. This solves the problem of the aging of the bearing 402 affecting the detection effect after long-term use of the viscometer.

[0052] Reference Figure 2 and Figure 3 The outer surface of the connecting block 401 is provided with a sliding groove, and the splash cover 5 fits tightly with the sliding groove;

[0053] Specifically, the top of the inner wall of the splash cover 5 is provided with a protrusion that fits into the groove on the outer surface of the connecting block 401, so that the splash cover 5 is fixed to the bottom of the connecting block 401 by snapping, making it easy to install and remove.

[0054] Reference Figure 2 and Figure 4 The cleaning brush 7 is in close contact with the rotor 15 and the connecting rod 14, and the cleaning brush 7 rotates under the drive of the second motor 10.

[0055] Specifically, the cleaning brush 7 rotates individually via the linkage 9 and the second motor 10, repeatedly brushing the rotor 15 and connecting rod 14 during rotation, thus completing a thorough cleaning in combination with the cleaning fluid.

[0056] Reference Figure 4 The cylinder 11 is fixedly connected to the component box 13. When the cylinder 11 is activated, it pushes the cleaning brush 7 to move.

[0057] Specifically, before use, the cylinder 11 retracts, widening the gap between the two rows of cleaning brushes 7, making it easier to insert the rotor 15 and connecting rod 14. During cleaning, the cylinder 11 extends, bringing the gap between the two rows of cleaning brushes 7 closer, allowing the cleaning brushes 7 to fully fit the rotor 15 and connecting rod 14.

[0058] Reference Figure 2 , Figure 5 and Figure 6The bottom of the connecting rod 14 passes through the detection disk 3, the connecting block 401 and the bearing 402 in sequence, and the connecting rod 14 rotates under the drive of the first motor 2;

[0059] Specifically, the connecting rod 14 is driven by the first motor 2. When it passes through the detection disk 3, it connects with the components in the detection disk 3 to detect the viscosity of the curing agent. After passing through the detection disk 3, the connecting block 401 and the bearing 402, the bottom of the connecting rod connects with the rotor 15.

[0060] Reference Figure 3 and Figure 4 The bottom of the two water spray pipes 8 is fixedly connected to the top of the component box 13, and the two water spray pipes 8 spray water into the middle of the cleaning cup 6;

[0061] Specifically, by setting two water spray pipes 8 on the left and right sides of the component box 13, when the water pump 12 is started, both spray water towards the middle at the same time, making the cleaning more comprehensive.

[0062] Reference Figure 1 and Figure 2 Magnets are provided on the top of the cleaning cup 6 and the top of the inner wall of the splash cover 5, and the cleaning cup 6 and the splash cover 5 are tightly fitted together;

[0063] Specifically, the magnets for both the cleaning cup 6 and the splash guard 5 are located inside the cup, making installation and removal convenient during cleaning.

[0064] Working principle: When testing the viscosity of the curing agent, the splash cover 5 is fixed to the bottom of the connecting block 401 by snap-fit, which is convenient for disassembly and assembly. After the splash cover 5 is installed, the monitoring part is lowered by adjusting the bracket 1 so that the splash cover 5 completely covers the container holding the curing agent. Then the first motor 2 is started to perform the test. After the test is completed, the adjusting bracket 1 is moved up and the cleaning cup 6 is installed at the bottom of the splash cover 5. The two second motors 10 are started to make the cleaning brushes 7 on both sides squeeze towards the connecting rod 14 and rotor 15 in the middle. The water pump 12 is started to make the water spray pipes 8 on both sides spray the cleaning liquid towards the middle. The second motor 10 drives the linkage 9 to make the individual cleaning brush 7 rotate. During the rotation, the rotor 15 and connecting rod 14 are repeatedly brushed lightly, thereby cleaning the connecting rod 14 and rotor 15.

[0065] When the connecting rod 14 is driven to rotate by the first motor 2, its rotation speed is adjusted to a fixed speed by the first motor 2. While the connecting rod 14 is rotating, the laser tachometer 406 monitors the rotation speed of the connecting rod 14 in real time. When the rotation speed of the connecting rod 14 becomes slow, the laser tachometer 406 issues an abnormal alarm and drives the two oil cans 404 to start. Oil is supplied to the inside of the bearing 402 through the oil supply pipe 405 and the groove 403 for lubrication. When the first motor 2 is restarted and the rotation speed of the connecting rod 14 is normal, the laser tachometer 406 no longer issues an alarm.

[0066] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
