Description

Technical Field

[0001] This utility model relates to the field of leveling technology for measuring devices, and more specifically, to an automatic leveling system for viscosity measuring devices. Background Technology

[0002] The viscosity of a melt or liquid is a key parameter affecting its flow, heat transfer, and crystal growth processes. Accurate measurement or characterization of these parameters is essential for optimizing process conditions and ensuring product quality.

[0003] Existing high-temperature viscometers generally use manual adjustment to adjust their position (such as vertical and horizontal displacement, and the levelness of the viscometer). Due to the significant influence of the adjustment personnel's subjectivity, this adjustment method has poor accuracy (or the accuracy is not easy to control), resulting in a large deviation between the measured data and the actual value. Utility Model Content

[0004] The purpose of this invention is to provide an automatic leveling system for viscosity measuring devices, addressing the technical problem that existing viscometers use manual adjustment, which suffers from poor accuracy (or difficulty in controlling accuracy), leading to large deviations between measured data and actual values. Therefore, this invention achieves this through the following solution.

[0005] An automatic leveling system for a viscosity measuring device includes:

[0006] Base;

[0007] The fixing plate has a first through hole;

[0008] The first mounting plate has one end connected to the horizontal surface of the base and the other end connected to the fixing plate;

[0009] A first rotating mechanism has a first rotating shaft, the first rotating shaft passes through the first through hole and the first rotating mechanism is disposed on the fixed plate on the side away from the base;

[0010] The movable block has a second through hole, and the first rotating shaft has a threaded groove in the circumferential direction. The first rotating shaft passes through the second through hole and is threadedly connected to the movable block.

[0011] The mounting rod is connected to the movable block and is used to mount the viscosity measuring device.

[0012] Compared with the prior art, in the automatic leveling system for a viscosity measuring device of this utility model, the base is used to stably support the entire leveling system, the first mounting plate is used to connect the base and the fixed plate, the fixed plate is used to fix the first rotating mechanism, and after the moving block is connected to the mounting rod, the height of the viscosity measuring device (or viscometer) can be adjusted by moving the moving block along the first rotating axis. Generally, during the viscosity measurement process, it is necessary to ensure that the rotor of the viscosity measuring device remains in a vertical state. In this solution, to keep the rotor in a vertical state, during the process of connecting the mounting rod to the moving block, or during the process of connecting the viscosity measuring device to the mounting rod, the position of the mounting rod or the viscosity measuring device is adjusted (by rotation) to keep the rotor in a vertical state. Furthermore, during the use of this automatic leveling system, a viscosity measuring device (or viscometer) can first be installed on the mounting rod. During installation, ensure the rotor remains vertical. Move the leveling system to position the viscosity measuring device close to the melt or liquid to be measured, and position the rotor directly above it. Activate the first rotating mechanism; the first rotating shaft will then rotate. Since the first rotating shaft is threadedly connected to the moving block, the moving block can move along the direction of the first rotating shaft as it rotates. The specific direction of movement (up or down) of the moving block can be determined by rotating the first rotating shaft. The rotation direction (clockwise or counterclockwise) is controlled; further, the rotation direction of the first rotating shaft is controlled so that the moving block moves towards the surface of the melt or liquid to be measured (downward) until the rotor connected to the viscosity measuring device extends below the liquid or melt surface, and the first rotating mechanism is closed; further, after the viscosity measurement of the melt or liquid is completed, the first rotating mechanism is restarted, and the first rotating shaft is controlled to rotate in the opposite direction to the previous one, and the moving block connected to the first rotating shaft moves away from the surface of the melt or liquid (upward) until the rotor connected to the viscosity measuring device leaves the liquid or melt. According to the above implementation process, it can be seen that in the process of connecting the viscosity measuring device (or viscometer) to the mounting rod, the viscosity measuring device can be adjusted first to keep the rotor vertical, and then the height of the viscosity measuring device (or viscometer) can be adjusted through the first rotating shaft, thereby achieving leveling of the viscosity measuring device. This technical solution eliminates the need for manual adjustment after the viscosity measuring device is installed. Leveling is achieved simply by starting or stopping the first rotating mechanism. Because it is unaffected by the operator's subjective judgment, or the influence is minimal, it offers high adjustment accuracy. Furthermore, automated leveling can be achieved by controlling the first rotating mechanism via a controller. This solution solves the technical problem of existing viscometers using manual adjustment methods, which suffer from poor accuracy (or difficulty in controlling accuracy), leading to large deviations between measured data and actual values.

Detailed Implementation

[0055] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0056] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0058] Existing high-temperature viscometers generally use manual adjustment to adjust their position (such as vertical and horizontal displacement, and the levelness of the viscometer). Due to the significant influence of the adjustment personnel's subjectivity, this adjustment method has poor accuracy (or the accuracy is not easy to control), resulting in a large deviation between the measured data and the actual value.

[0059] Please see Figures 1 to 11To solve the above-mentioned technical problems, this utility model provides an automatic leveling system for a viscosity measuring device, including a base 1, a fixed plate 2, a first mounting plate 3, a first rotating mechanism 4, a moving block 5, and a mounting rod 6; wherein, the fixed plate 2 has a first through hole 201, one end of the first mounting plate 3 is connected to the horizontal surface of the base 1, and the other end is connected to the fixed plate 2, the first rotating mechanism 4 has a first rotating shaft 401, the first rotating shaft 401 passes through the first through hole 201 and is positioned on the fixed plate 2 away from the base 1, the moving block 5 has a second through hole, the first rotating shaft 401 has a threaded groove in the circumference, the first rotating shaft 401 passes through the second through hole and is threadedly connected to the moving block 5, and the mounting rod 6 is connected to the moving block 5 and is used to mount the viscosity measuring device 25.

[0060] Specific implementation process: First, install the viscosity measuring device 25 (or viscometer) on the mounting rod 6. During installation, ensure the rotor remains vertical. Move the leveling system to position the viscosity measuring device 25 close to the melt or liquid to be measured, and position the rotor directly above the melt or liquid. Activate the first rotating mechanism 4, and the first rotating shaft 401 rotates accordingly. Since the first rotating shaft 401 is threadedly connected to the moving block 5, the moving block 5 can move along the direction of the first rotating shaft 401. The specific direction of movement of the moving block 5 (upward or downward) can be determined by the rotation direction of the first rotating shaft 401 (clockwise). (Or counterclockwise) control; further, control the rotation direction of the first rotating shaft 401, the purpose of which is to move the moving block 5 towards the surface of the melt or liquid to be measured (downward) until the rotor connected to the viscosity measuring device extends below the liquid surface of the liquid or melt, and close the first rotating mechanism 4; further, after the viscosity measurement of the melt or liquid is completed, restart the first rotating mechanism 4, and control the first rotating shaft 401 to rotate in the opposite direction to the previous one, and move the moving block 5 connected to the first rotating shaft 401 away from the surface of the melt or liquid (upward) until the rotor connected to the viscosity measuring device leaves the liquid or melt.

[0061] As can be seen from the above technical solution and specific implementation process, in the automatic leveling system for the viscosity measuring device of this utility model, the base 1 is used to stably support the entire leveling system, the first mounting plate 3 is used to connect the base 1 and the fixing plate 2, the fixing plate 2 is used to fix the first rotating mechanism 4, and after the moving block 5 is connected to the mounting rod 6, the height of the viscosity measuring device (or viscometer) can be adjusted by moving the moving block 5 along the direction of the first rotating shaft 401. Generally, during the viscosity measurement process, it is necessary to ensure that the rotor of the viscosity measuring device remains vertical. In this solution, to keep the rotor vertical, during the process of connecting the mounting rod 6 to the moving block 5, or during the process of connecting the viscosity measuring device to the mounting rod 6, the position of the mounting rod 6 or the viscosity measuring device can be adjusted (by rotation) to keep the rotor vertical. As can be seen from the above implementation process, in the process of connecting the viscosity measuring device (or viscometer) to the mounting rod 6, the viscosity measuring device can be adjusted first to keep the rotor vertical, and then the height of the viscosity measuring device (or viscometer) can be adjusted by the first rotating shaft 401, thereby achieving the leveling of the viscosity measuring device. This technical solution eliminates the need for manual adjustment after the viscosity measuring device is installed. Leveling is achieved simply by starting or stopping the first rotating mechanism 4. Because it is unaffected by the operator's subjective judgment, or the influence is minimal, it offers high adjustment accuracy. Furthermore, automated leveling can be achieved by controlling the first rotating mechanism via a controller. This solution solves the technical problem of existing viscometers using manual adjustment methods, which suffer from poor accuracy (or difficulty in controlling accuracy), leading to large deviations between measured data and actual values.

[0062] In one possible implementation, the automatic leveling system for a viscosity measuring device of this invention further includes a second mounting plate 7, which is fixedly connected to the moving block 5, and a mounting rod 6 is connected to the second mounting plate 7. With this technical solution, the second mounting plate 7 provides stable support for the mounting rod 6 (used to connect the viscosity measuring device) relative to the moving block 5.

[0063] As one possible implementation, the automatic leveling system for a viscosity measuring device of this utility model further includes a first slide rail 8, a second slide rail 9, a first slider 10, and a second slider 11; wherein, the first slide rail 8 and the second slide rail 9 are provided on the first mounting plate 3 near the first rotating shaft 401 (this describes the position of the first slide rail 8 and the second slide rail 9 on the mounting plate 3), and the first slide rail 8 and the second slide rail 9 are arranged opposite to each other on both sides of the first rotating shaft 401; the first slider 10 is matched and connected to the first slide rail 8, the second slider 11 is matched and connected to the second slide rail 9, and the first slider 10 and the second slider 11 are fixedly connected to the second mounting plate 7.

[0064] With the above technical solution, in the automatic leveling system for the viscosity measuring device of this utility model, the first slide rail 8 is matched with the first slider 10, and the second slide rail 9 is matched with the second slider 11. That is, the first slider 10 can slide on the first slide rail 8, and the second slider 11 can slide on the second slide rail 9. After the first slider 10 and the second slider 11 are fixedly connected to the second mounting plate 7, the first slide rail 8 and the second slide rail 9 matched with the first slider 10 and the second slider 11 respectively provide guidance and support for the second mounting plate 7, so as to ensure that the second mounting plate 7 (and the viscosity measuring device on it) maintains stability and linear motion during movement. In general, this technical solution further improves the stability of the leveling system during use and further improves the accuracy of viscosity measurement values.

[0065] In one possible implementation, in the automatic leveling system for a viscosity measuring device of the present invention, the second mounting plate 7 is provided with a groove along the direction of the first rotation axis 401 on the side away from the moving block 5. The automatic leveling system also includes a baffle 12 and a third mounting plate 13. The baffle 12 is disposed in the groove, and one end of the baffle 12 is connected to the base 1 and the other end is connected to the fixed plate 2. The third mounting plate 13 is fixedly connected to the second mounting plate 7, and the mounting rod 6 is connected to the third mounting plate 13. With this technical solution, the baffle 12 further improves the stability of the leveling system. Specifically, one end of the baffle 12 is connected to the base 1, and the other end is connected to the fixed plate 2, thus forming a stable support structure. Since the baffle 12 is set in the groove of the second mounting plate 7, the groove and the baffle 12 can serve as a pair of sliding components (the baffle 12 is a slide rail, and the second mounting plate 7 is a slider, that is, the second mounting plate 7 can slide along the baffle 12). This is equivalent to providing guidance and support for the second mounting plate 7 on the basis of the existing pair of slide rails and sliders (the first slide rail 8 and the first slider 10, the second slide rail 9 and the second slider 11), further improving the stability of the leveling system during use and further improving the accuracy of viscosity measurement.

[0066] As one possible implementation, the automatic leveling system for a viscosity measuring device of the present invention further includes a fourth mounting plate 14 and a second rotating mechanism 15 having a second rotating shaft 1501; wherein, any end of the fourth mounting plate 14 is connected to the third mounting plate 13, the second rotating mechanism 15 is disposed on the side of the fourth mounting plate 14 away from the base 1, the mounting rod 6 is connected to the second rotating shaft 1501, the second rotating shaft 1501 is perpendicular to the first rotating shaft, parallel to the horizontal plane of the base 1, and parallel to the mounting rod 6.

[0067] With the above technical solution, in the automatic leveling system for the viscosity measuring device of this utility model, as mentioned above, during the installation of the viscosity measuring device 25 (or viscometer), the rotor connected to the viscosity measuring device (or viscometer) can be adjusted to maintain a vertical state; during the subsequent use of the automatic leveling system, the viscosity measuring device (or viscometer) will inevitably move or deflect to varying degrees, which will lead to the rotor tilting. Therefore, this technical solution further includes a second rotating mechanism 15 for adjusting the rotor to maintain its vertical position. Specifically, since the second rotating shaft 1501 is perpendicular to the first rotating shaft, parallel to the horizontal plane of the base 1, and parallel to the mounting rod 6, activating the second rotating mechanism 15 causes the second rotating shaft 1501 to rotate. Consequently, the second rotating shaft 1501 drives the mounting rod 6 connected to it to rotate. Since the mounting rod 6 is connected to a viscosity measuring device (or viscometer), the viscosity measuring device (or viscometer) will also rotate. It should be noted that during this process, only a small angle needs to be rotated on the second rotating shaft 1501 to adjust the rotor (which is connected to the viscosity measuring device or viscometer) to maintain its vertical position.

[0068] As one possible implementation, the automatic leveling system for a viscosity measuring device of this utility model further includes a third rotating mechanism 16 having a third rotating shaft 1601, and a limiting block 17; wherein, the limiting block 17 has a third through hole, the third rotating shaft 1601 passes through the third through hole and is slidably connected to the limiting block 17, the second rotating shaft 1501 of the second rotating mechanism 15 is fixedly connected to the limiting block 17; the third rotating shaft 1601 is fixedly connected to the mounting rod 6, the mounting rod 6 is parallel to the third rotating shaft 1601, and the second rotating shaft 1501 is perpendicular to the third rotating shaft 1601.

[0069] With the above technical solution, in the automatic leveling system for the viscosity measuring device of this utility model, since the third rotating shaft 1601 is fixedly connected to the mounting rod 6, the mounting rod 6 is parallel to the third rotating shaft 1601, and the second rotating shaft 1501 is perpendicular to the third rotating shaft 1601, the automatic leveling system can be rotated and leveled in the x-axis direction or y-axis direction (the second rotating shaft 1501 and the third rotating shaft 1601 are orthogonal). Specifically, the direction of the second rotating shaft 1501 is set as the x-axis direction, and the second rotating mechanism 15 is started. Since the third rotating shaft 1601 passes through the third through hole and is slidably connected to the limiting block 17, the second rotating shaft 1501 of the second rotating mechanism 15 is fixedly connected to the limiting block 17. The second rotating shaft 1501 drives the third rotating mechanism 16 and the mounting rod 6 to rotate together, so that the viscosity measuring device 25 (or viscometer) rotates in the x-axis direction (i.e., along the second rotating shaft 1501), thereby realizing the leveling of the viscosity measuring device 25 in the x-axis direction (i.e., along the second rotating shaft 1501). Leveling is performed; further, the direction of the third rotating shaft 1601 is set as the y-axis direction, and the third rotating mechanism 16 is started. Since the third rotating shaft 1601 is fixedly connected to the mounting rod 6, and the mounting rod 6 is parallel to the third rotating shaft 1601, the third rotating shaft 1601 drives the mounting rod 6 (the mounting rod 6 is connected to a viscosity measuring device or viscometer) to rotate together, so that the viscosity measuring device 25 (or viscometer) rotates along the y-axis direction (i.e., along the third rotating shaft 1601), thereby achieving leveling of the viscosity measuring device 25 in the direction of the third rotating shaft 1601.

[0070] In one possible implementation, the automatic leveling system for the viscosity measuring device of this utility model includes a first mounting rod 601 and a second mounting rod 602; one end of the first mounting rod 601 is perpendicularly connected to the third rotating shaft 1601, and the other end is perpendicularly connected to the second mounting rod 602, which is used to mount the viscosity measuring device; the first mounting rod 601 and the second mounting rod 602 are parallel to the horizontal plane of the base 1.

[0071] In the automatic leveling system for a viscosity measuring device of this invention, where the mounting rod 6 is configured as a first mounting rod 601 and a second mounting rod 602, and one end of the first mounting rod 601 is perpendicularly connected to the third rotating shaft 1601, and the other end is perpendicularly connected to the second mounting rod 602, the first mounting rod 601 and the second mounting rod 602 are perpendicularly connected. For a certain length of the second mounting rod 602 (the set length is fixed), its connection position with the first mounting rod 601 can be controlled, thereby controlling the distance between the second mounting rod 602 and the first mounting rod 601. In other words, if the second mounting rod 602 is too long, a portion of it can be connected to the first mounting rod 601, extending into the interior of the first mounting rod 601 or to the other side, effectively reducing the extension length of the second mounting rod 602. The second mounting rod 602 is used to connect the viscosity measuring device (or viscometer). It can also be considered that by controlling the second mounting rod 602... The connection position with the first mounting rod 601 is used to control the distance between the second mounting rod 602 and the first mounting rod 601, thereby controlling the distance between the viscosity measuring device (or viscometer) and the third rotating shaft 1601, or to the fourth mounting plate 14, or to the third mounting plate 13 within a reasonable range. In general, the viscosity measuring device (or viscometer) can be set in a suitable position in the leveling system according to different usage environments to facilitate viscosity measurement. For example, a through hole is provided on the first mounting rod 601, which matches the outer diameter of the second mounting rod 602. The through hole is used to connect the second mounting rod 602. The connection between the first mounting rod 601 and the second mounting rod 602 can be achieved by extending the second mounting rod 602 into the through hole. Furthermore, by controlling the length of the second mounting rod 602 extending into the through hole, the effective length of the second mounting rod 602 (the effective length is the distance between the second mounting rod 602 and the first mounting rod 601) can be changed.

[0072] As one possible implementation, the automatic leveling system for a viscosity measuring device of this utility model further includes an installation strip 18, a first locking strip 19, a second locking strip 20, and a limiting strip 21; wherein, one end of the installation strip 18 is connected to the base 1, and the other end is connected to the fixing plate 2, the installation strip 18 is disposed on either side of the first rotating shaft 401, the first locking strip 19 and the second locking strip 20 are both disposed on the side of the installation strip 18 away from the first rotating shaft 401, and there is a gap between the first locking strip 19 and the second locking strip 20; the limiting strip 21 is disposed on the side of the second mounting plate 7 near the installation strip 18, and the limiting strip 21 extends between the first locking strip 19 and the second locking strip 20.

[0073] In the above-described automatic leveling system for a viscosity measuring device, as described above, since the first rotating shaft 401 of the first rotating mechanism 4 is circumferentially provided with a threaded groove, and after the first rotating shaft 401 is threadedly connected to the moving block 5, as long as the first rotating shaft 401 continues to rotate in one direction (clockwise or counterclockwise), the moving block 5 can reach as far as the end of the first rotating shaft 401 near the base 1 and as close as the end of the first rotating shaft 401 away from the base 1. In practical applications, i.e., during viscosity measurement, vertical adjustment (i.e., height) often only requires the rotor to extend into or away from the surface of the melt (or liquid) to be measured. However, no significant adjustments are needed. Therefore, the placement of the first locking bar 19 and the second locking bar 20 limits the movement range (or distance) of the moving block 5 on the first rotating shaft 401. Specifically, when the first rotating mechanism 4 is activated, the first rotating shaft 401 rotates (in either direction), and the moving block 5 drives the second mounting plate 7 to move in one direction. Since the limiting bar 21 is located on the second mounting plate 7 near the mounting bar 18 and extends between the first locking bar 19 and the second locking bar 20, the limiting bar 21 will abut against the first locking bar 19 or the second locking bar 20 during the movement of the moving block 5, thereby limiting the continued movement of the second mounting plate 7 (or the moving block 5). For example, the first rotating mechanism 4 is a motor. After the limiting bar 21 abuts against the first locking bar 19 or the second locking bar 20, the signal controller connected to the motor detects the resistance and cuts off the pulse signal (i.e., does not provide a pulse signal), and the motor stops working. This controls the movement distance of the second mounting plate 7 (or the moving block 5) while protecting the motor from overload.

[0074] As one possible implementation, the automatic leveling system for a viscosity measuring device of this invention further includes a first inclined brace 22 and a second inclined brace 23, each having a first support surface and a second support surface. The first inclined brace 22 and the second inclined brace 23 are positioned opposite each other on the horizontal plane of the base 1 via the first support surface, and are connected to the side of the first mounting plate 3 away from the moving block 5 via the second support surface. With this technical solution, by first installing the inclined braces (first inclined brace 22 or second inclined brace 23) to the base 1, a stable triangular support structure is formed between the base 1 and the first mounting plate 3. This improves the overall stability of the leveling system and effectively resists external forces, preventing the leveling system from tilting or shifting due to vibration or external forces during use, thereby ensuring the accuracy and reliability of viscosity measurement.

[0075] As one possible implementation, the automatic leveling system for a viscosity measuring device of this invention further includes a tilt sensor 24 and a controller; wherein, the tilt sensor 24 is mounted on the viscosity measuring device, the controller is electrically connected to the tilt sensor 24, the first rotating mechanism 4 is electrically connected to the controller, the second rotating mechanism 15 is electrically connected to the controller, and the third rotating mechanism 16 is electrically connected to the controller.

[0076] In the automatic leveling system for a viscosity measuring device of this invention, the tilt sensor 24 installed on the viscosity measuring device 25 is used to detect the levelness of the viscosity measuring device (the viscosity measuring device 25 is connected to a rotor, so it can also be considered as measuring the levelness of the rotor), and transmits the detection signal to the controller. Furthermore, the controller is also equipped with a control program, which controls the activation of the first rotating mechanism 4, the second rotating mechanism 15, or the third rotating mechanism 16, the rotation angle of the corresponding rotating shaft (such as the first rotating shaft 401, the second rotating shaft 1501, or the third rotating shaft 1601), and the closure of the first rotating mechanism 4, the second rotating mechanism 15, or the third rotating mechanism 16, thereby achieving intelligent or automated control of the automatic leveling system. For example, the control program sets height and levelness values. When the height and levelness of the viscosity measuring device are inconsistent with the set values, or when they exceed or fall below the set values, the controller can control the first rotating mechanism 4, the second rotating mechanism 15, or the third rotating mechanism 16 for adjustment.

[0077] In one possible implementation, in the automatic leveling system for a viscosity measuring device of this invention, the second rotating mechanism 15 can be a motor, and a reduction gearbox is provided on the second rotating shaft 1501; the third rotating mechanism 16 can also be a motor, and the aforementioned limiting block 17 can be set as the reduction gearbox of the third rotating mechanism 16. With this technical solution, the reduction gearbox on the second rotating shaft 1501 is used to control the rotational speed of the second rotating shaft 1501 (actually, to reduce the rotational speed of the second rotating shaft 1501), thereby improving the accuracy of adjustment (slower rotational speed is easier to adjust, thus avoiding or reducing errors), and the reduction ratio of the reduction gearbox can be 50:1; since the limiting block 17 is set as the reduction gearbox of the third rotating mechanism 16, which is used to control the rotational speed of the third rotating shaft 1601, thereby improving the accuracy of adjustment, the reduction ratio of the reduction gearbox can also be 50:1.
