Description

Technical Field

[0001] This utility model relates to the field of agitator inspection, and in particular to a tool for detecting the level of an agitator in a glass melt channel. Background Technology

[0002] In the glass production process, stirring of the molten glass is a core step in ensuring product quality. Through forced convection, stirring can effectively eliminate the temperature gradient of the molten glass, making its viscosity uniform, thereby ensuring the stable flow of the molten glass during the forming process and avoiding deformation, internal stress concentration or optical performance defects in glass products caused by uneven temperature distribution.

[0003] The agitator includes a mounting base, with an agitator shaft at the bottom of the mounting base and agitator blades below the agitator shaft. However, dimensional deviations may occur during the machining of the agitator shaft. These deviations can cause the agitator shaft to be misaligned with the output shaft of the drive motor after installation, resulting in the agitator shaft tilting during rotation. This tilting of the agitator shaft can lead to inconsistent depths of the agitator blades into the molten glass, resulting in an unbalanced distribution of shear force in the molten glass within the feed channel. This can prevent the effective elimination of temperature gradients and cause streaks or uneven refractive index in the glass products. Therefore, the agitator needs to be leveled during installation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a level detection tool for the stirring paddle of a glass liquid channel. The purpose is to solve the technical problem that deviations occur during the processing of the stirring shaft or mounting base, which cause the stirring shaft to be misaligned with the output shaft of the drive electrode after installation, resulting in the stirring shaft being tilted during rotation.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A tool for leveling a stirring paddle in a molten glass feed channel includes a support base, a support plate vertically mounted on the top of the support base, a drive frame mounted on one side of the support plate, a test motor mounted on the top of the drive frame, a transmission shaft passing through the interior of the drive frame, one end of the transmission shaft extending out of the bottom of the drive frame, the test motor driving the transmission shaft to rotate, a rotating seat mounted on one end of the transmission shaft, an installation cavity formed on one side of the rotating seat, a detachable mounting seat mounted inside the installation cavity, a stirring shaft mounted at the bottom of the mounting seat, a stirring blade mounted at one end of the stirring shaft, an adjusting seat mounted inside the support plate, a test rod passing through the adjusting seat, a test end mounted at one end of the test rod, the test end being close to the stirring shaft, thus creating a test interval between the test end and the stirring shaft.

[0007] When the test motor starts, it drives the transmission shaft to rotate. The transmission shaft, through the rotating seat, drives the stirring shaft installed in the mounting cavity to rotate synchronously, thus simulating the rotation state of the stirring shaft installed in the material channel. Since the test end is close to the stirring shaft, when the stirring shaft tilts due to machining dimensional errors, the trajectory of the stirring shaft will deviate from the axis when rotating. The eccentric trajectory causes the test end and the stirring shaft to be separated, forming a test interval that changes periodically with rotation, resulting in a gap fluctuation that can be seen with the naked eye. By observing the fluctuation amplitude and pattern of the test interval, combined with the periodic change of the stirring shaft's rotation, the test personnel can determine whether there is a large fluctuation in the test interval. If there is a large fluctuation in the test interval, it is judged that the stirring shaft has a machining dimensional error. If there is no large fluctuation in the test interval, it is judged that the stirring shaft is qualified, thus preventing unqualified stirring shafts from being used in the material channel.

[0008] Furthermore, in this application, a through-groove is provided on one side of the rotating seat, the through-groove penetrates the bottom of the rotating seat, the through-groove communicates with the mounting cavity, the mounting seat slides with the mounting cavity, so that the stirring shaft passes through the through-groove, the rotating seat has first fixing holes on both sides, the first fixing holes communicate with the mounting cavity, the mounting seat has second fixing holes on both sides, fixing bolts are inserted in the first fixing holes, and the fixing bolts are threadedly engaged with the adjacent second fixing holes.

[0009] When the stirring shaft needs to be tested, the mounting base slides into the mounting cavity, and the first fixing holes on both sides of the rotating seat are aligned with the second fixing holes on both sides of the mounting base. By inserting and tightening the fixing bolts, the mounting base and the rotating seat are rigidly connected, which makes it easy to install the stirring shaft at the test position so as to observe the test interval formed between the test end and the stirring shaft.

[0010] Furthermore, in this application, the interior of the mounting cavity is provided with a guide slider, and one side of the mounting base is provided with a guide groove, the guide groove being in sliding engagement with the guide slider.

[0011] When the mounting base slides into the mounting cavity, the guide groove of the mounting base slides in conjunction with the guide slider, which facilitates the guidance of the mounting base's sliding position and prevents the stirring shaft from tilting due to manual installation position deviation, thus affecting the test results.

[0012] Furthermore, in this application, the drive frame has a rotating groove inside, and a stabilizing bearing is provided inside the rotating groove. The drive shaft passes through the inner ring of the stabilizing bearing, so that the drive shaft and the inner ring of the stabilizing bearing are in rotational engagement.

[0013] Furthermore, in this application, the support plate has an adjustment groove vertically formed inside, the adjustment seat slides with the adjustment groove, the adjustment groove is located below the drive frame, the adjustment seat has first locking holes on both sides, the support plate has multiple second locking holes at both ends, a locking bolt passes through any of the second locking holes at both ends of the support plate, and the locking bolt is threaded with the adjacent first locking hole.

[0014] Furthermore, in this application, the adjusting seat is provided with adjusting sliders on both sides, and the adjusting groove is provided with adjusting slide grooves on both sides, and the adjusting sliders on both sides of the adjusting seat slide in cooperation with the adjusting slide grooves on both sides of the adjusting groove.

[0015] Furthermore, in this application, the adjusting seat has a first movable groove inside, and the test rod slides in conjunction with the first movable groove.

[0016] Furthermore, in this application, one end of the adjusting seat is provided with a fixed cylinder, and a second movable groove is provided inside the fixed cylinder. The second movable groove communicates with the first movable groove. The other end of the test rod passes through the second movable groove, so that the other end of the test rod slides into the second movable groove. A fastening hole is provided on one side of the fixed cylinder, and a fastening bolt is threaded into the fastening hole, so that the fastening bolt abuts against the test rod.

[0017] Furthermore, in this application, the other end of the test rod is provided with a limiting block, the size of which is larger than the size of the second movable groove.

[0018] Furthermore, in this application, a reinforcing side frame is provided on the other side of the support plate. The reinforcing side frame is connected to the top of the support base, and the reinforcing side frame, the support base, and the support plate surround each other to form a triangular shape.

[0019] This utility model has the following beneficial effects:

[0020] When the test motor starts, it drives the transmission shaft to rotate. The transmission shaft, through the rotating seat, drives the stirring shaft installed in the mounting cavity to rotate synchronously, thus simulating the rotation state of the stirring shaft installed in the material channel. Since the test end is close to the stirring shaft, when the stirring shaft tilts due to machining dimensional errors, the trajectory of the stirring shaft will deviate from the axis when rotating. The eccentric trajectory causes the test end and the stirring shaft to be separated, forming a test interval that changes periodically with rotation, resulting in a gap fluctuation that can be seen with the naked eye. By observing the fluctuation amplitude and pattern of the test interval, combined with the periodic change of the stirring shaft's rotation, the test personnel can determine whether there is a large fluctuation in the test interval. If there is a large fluctuation in the test interval, it is judged that the stirring shaft has a machining dimensional error. If there is no large fluctuation in the test interval, it is judged that the stirring shaft is qualified, thus preventing unqualified stirring shafts from being used in the material channel.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features.

[0031] Reference Figures 1-5In some specific embodiments, a glass liquid feed channel stirring paddle level detection tool includes a support base 1, a support plate 2 vertically mounted on the top of the support base 1, a drive frame 3 mounted on one side of the support plate 2, a test motor 4 mounted on the top of the drive frame 3, a transmission shaft 8 passing through the inside of the drive frame 3, one end of the transmission shaft 8 passing through the bottom of the drive frame 3, the test motor 4 driving the transmission shaft 8 to rotate, a rotating seat 11 mounted on one end of the transmission shaft 8, an installation cavity 14 opened on one side of the rotating seat 11, a detachable mounting seat 6 mounted inside the mounting cavity 14, a stirring shaft 5 mounted at the bottom of the mounting seat 6, a stirring blade 36 mounted at one end of the stirring shaft 5, an adjusting seat 19 mounted inside the support plate 2, a test rod 28 passing through the adjusting seat 19, a test end 34 mounted at one end of the test rod 28, the test end 34 being close to the stirring shaft 5, so that the test end 34 and the stirring shaft 5 are separated to form a test interval 32.

[0032] Through the above technical solution, when the test motor 4 starts, the test motor 4 drives the transmission shaft 8 to rotate. The transmission shaft 8 drives the stirring shaft 5 installed in the installation cavity 14 to rotate synchronously through the rotating seat 11, thereby simulating the rotation state of the stirring shaft 5 installed in the material channel. Since the test end 34 is close to the stirring shaft 5, when the stirring shaft 5 tilts due to processing size error, the trajectory of the stirring shaft 5 will deviate from the axis when rotating. The eccentric trajectory causes the test end 34 and the stirring shaft 5 to be separated, forming a test interval 32 that changes periodically with rotation (e.g., the test interval 32 shrinks when the inclined surface of the stirring shaft 5 is close to the test end 34, and increases when the inclined surface of the stirring shaft 5 is far away from the test end 34), forming a gap fluctuation that can be seen with the naked eye. By observing the fluctuation amplitude and pattern of the test interval 32, combined with the periodic change of the stirring shaft 5 rotating one revolution, the test personnel can determine whether the test interval 32 has a large fluctuation. If the test interval 32 has a large fluctuation, it is judged that the stirring shaft 5 has a processing size error. If the test interval 32 does not have a large fluctuation, it is judged that the stirring shaft 5 is qualified, thereby preventing unqualified stirring shafts 5 from being used in the material channel.

[0033] In addition, a distance sensor can be set at one end of the test end 34 so that when the stirring shaft 5 rotates, the distance sensor will identify whether the distance between the stirring shaft 5 and the stirring shaft 5 changes significantly during rotation. If the identified distance data changes significantly, the stirring shaft 5 is judged to be unqualified in size. If the identified distance data does not change significantly, the stirring shaft 5 is judged to be qualified, thereby improving the detection efficiency of the stirring shaft 5.

[0034] Reference Figure 4In some specific embodiments, a through-groove 35 is provided on one side of the rotating seat 11, the through-groove 35 penetrates the bottom of the rotating seat 11 and connects to the mounting cavity 14. The mounting seat 6 slides with the mounting cavity 14, so that the stirring shaft 5 passes through the through-groove 35. First fixing holes 12 are provided on both sides of the rotating seat 11, and the first fixing holes 12 connect to the mounting cavity 14. Second fixing holes 17 are provided on both sides of the mounting seat 6. Fixing bolts 13 are inserted in the first fixing holes 12 and are threadedly engaged with the adjacent second fixing holes 17.

[0035] With the above technical solution, when it is necessary to test the stirring shaft 5, the mounting base 6 slides into the mounting cavity 14, the first fixing holes 12 on both sides of the rotating base 11 are aligned with the second fixing holes 17 on both sides of the mounting base 6, and the mounting base 6 and the rotating base 11 are rigidly connected by inserting and tightening the fixing bolts 13, so as to facilitate the installation of the stirring shaft 5 at the test position, so as to facilitate the observation that the test end 34 and the stirring shaft 5 are separated to form a test interval 32.

[0036] Reference Figures 3-4 In some specific embodiments, the cavity 14 is provided with a guide slider 15, and the mounting base 6 is provided with a guide groove 16 on one side, and the guide groove 16 slides in cooperation with the guide slider 15.

[0037] With the above technical solution, when the mounting base 6 slides into the mounting cavity 14, the guide groove 16 of the mounting base 6 and the guide slider 15 slide together, which facilitates the guidance of the sliding position of the mounting base 6, thereby preventing the stirring shaft 5 from tilting due to manual installation position deviation and affecting the test results.

[0038] Reference Figure 4 In some specific embodiments, a stabilizing seat 7 is provided on one side of the support plate 2. The stabilizing seat 7 is located below the drive frame 3. A rotating groove 9 is provided inside the stabilizing seat 7. A stabilizing bearing 10 is provided inside the rotating groove 9. The transmission shaft 8 passes through the inner ring of the stabilizing bearing 10, so that the transmission shaft 8 and the inner ring of the stabilizing bearing 10 rotate and cooperate.

[0039] Through the above technical solution, the drive shaft 8 passes through the inner ring of the stabilizing bearing 10. Through the precise fit of the balls or raceways inside the stabilizing bearing 10, the radial load of the drive shaft 8 (such as centrifugal force and lateral force caused by the eccentricity of the stirring shaft 5) is transmitted to the stabilizing seat 7, ensuring that the drive shaft 8 keeps its axis fixed during rotation and improving the accuracy of the stirring shaft 5 during detection.

[0040] Reference Figure 5In some specific embodiments, the support plate 2 has a vertically formed adjustment groove 18 inside, and the adjustment seat 19 is slidably engaged with the adjustment groove 18. The adjustment groove 18 is located below the drive frame 3. The adjustment seat 19 has first locking holes 22 on both sides, and the support plate 2 has multiple second locking holes 23 at both ends. A locking bolt 21 is inserted into any of the second locking holes 23 at both ends of the support plate 2, and the locking bolt 21 is threadedly engaged with the adjacent first locking hole 22.

[0041] Through the above technical solution, the vertical adjustment groove 18 inside the support plate 2 allows the adjustment seat 19 to slide freely up and down along the groove, driving the test rod 28 and the test end 34 to rise and fall synchronously, thereby adapting to the testing requirements of different height positions of the stirring shaft 5 (such as shaft top, shaft middle, and shaft root). When the adjustment seat 19 is adjusted to the corresponding position, the corresponding second locking hole 23 is inserted into the locking bolt 21, so that the locking bolt 21 is threadedly engaged with the adjacent first locking hole 22. After tightening, the height of the adjustment seat 19 can be locked, thereby preventing the adjustment seat 19 from moving when the stirring shaft 5 is tested.

[0042] Reference Figure 5 In some specific embodiments, the adjusting seat 19 is provided with adjusting sliders 20 on both sides, and the adjusting groove 18 is provided with adjusting grooves 24 vertically on both sides. The adjusting sliders 20 on both sides of the adjusting seat 19 slide in cooperation with the adjusting grooves 24 on both sides of the adjusting groove 18.

[0043] With the above technical solution, when the height of the adjusting seat 19 is adjusted, the adjusting sliders 20 on both sides of the adjusting seat 19 slide and engage with the adjusting grooves 24 on both sides of the adjusting groove 18, thereby restricting the adjusting seat 19 to move only in the vertical direction, eliminating the risk of horizontal offset or torsion, and improving the accuracy of the displacement when the adjusting seat 19 is adjusted.

[0044] Reference Figure 5 In some specific embodiments, the adjusting seat 19 has a first movable groove 25 inside, and the test rod 28 slides in the first movable groove 25.

[0045] Through the above technical solution, the initial test interval 32 between the test end 34 and the stirring shaft 5 can be finely adjusted by sliding the test rod 28 horizontally, adapting to the detection requirements of stirring shafts 5 with different diameters, and ensuring that the test end 34 is always at the optimal observation distance.

[0046] Reference Figure 5In some specific embodiments, one end of the adjusting seat 19 is provided with a fixed cylinder 26, and the inside of the fixed cylinder 26 is provided with a second movable groove 27, which is connected to the first movable groove 25. The other end of the test rod 28 passes through the second movable groove 26, so that the other end of the test rod 28 slides in the second movable groove 27. A fastening hole 30 is provided on one side of the fixed cylinder 26, and a fastening bolt 31 is threaded into the fastening hole 30, so that the fastening bolt 31 abuts against the test rod 28.

[0047] With the above technical solution, after the test end 34 is horizontally adjusted, the fastening bolt 31 is screwed into the fastening hole 30 of the fixing cylinder 26, so that the end of the fastening bolt 31 generates a frictional clamping force with the surface of the test rod 28. The test rod 28 is fixed in the target position by utilizing the self-locking characteristic of the thread, thereby resisting vibration or external force interference during the testing process and preventing the test end 34 from being displaced during the testing process.

[0048] Reference Figure 5 In some specific embodiments, the other end of the test rod 28 is provided with a limiting block 29, the size of which is larger than the size of the second movable groove 27.

[0049] With the above technical solution, when the test rod 28 slides toward the stirring shaft 5 to the limit position, the limiting block 29 contacts the port edge of the second movable groove 27, preventing the test rod 28 from continuing to slide out, thereby preventing the test rod 28 from accidentally detaching.

[0050] Reference Figures 1-2 In some specific embodiments, a reinforcing side frame 33 is provided on the other side of the support plate 2. The reinforcing side frame 33 is connected to the top of the support base 1, and the reinforcing side frame 33, the support base 1 and the support plate 2 surround each other to form a triangular shape.

[0051] Through the above technical solution, the side frame 33, the support base 1 and the support plate 2 are reinforced to form a triangular shape. By utilizing the natural anti-deformation characteristics of the triangular geometry, the external load (such as the torque of the drive shaft 8 and the vibration of the stirring shaft 5) is distributed to the three sides, avoiding bending or twisting of the support plate 2 on one side.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
