[0002] The tandem glass machine is a crucial piece of equipment for manufacturing glass tubes. Its core components include the main shaft and the rotating tube. The tandem machine uses a motor, reducer, and other mechanisms to drive the main shaft, which is mounted on the machine, to rotate. This causes the rotating tube, which is mounted on the main shaft, to rotate as well. Molten glass is wound onto the rotating tube, and processes such as blowing air are then performed to complete the glass tube manufacturing. As a critical component of the tandem machine, the main shaft requires high levels of straightness and concentricity.
[0003] However, during production, the main shaft is prone to bending and deformation due to prolonged operation at high temperatures. This can cause misalignment between the main shaft and the rotating tube, reducing the lifespan of the rotating tube and the quality of the glass tube, resulting in decreased economic benefits. Therefore, it is necessary to straighten the main shaft of the Danner machine to ensure its normal operation. Utility Model Content

[0031] See Figure 1 This disclosure provides a straightening device for the main shaft of a danner machine 3, including a measuring component 1 and a straightening component 2. The measuring component 1 is used to measure the curvature of the main shaft 31 of the danner machine 3. The straightening component 2 is spaced apart from the danner machine 3 along the axial direction of the main shaft 31 and is used to straighten the main shaft 31 on the danner machine 3 according to the curvature. The measuring component 1 provides accurate data for the straightening work of the straightening component 2. The straightening component 2 straightens the main shaft 31 according to the curvature data provided by the measuring component 1. The straightening component 2 is spaced apart from the danner machine 3 along the axial direction of the main shaft 31, so that the straightening device can directly straighten the main shaft 31 on the danner machine 3, ensuring the normal operation of the danner machine. Moreover, this danner machine main shaft straightening device does not require the main shaft 31 to be disassembled from the danner machine 3 for straightening, reducing the disassembly and transportation process of the main shaft 31, saving time and effort, and improving the straightening efficiency of the main shaft 31.
[0032] In some embodiments, after measuring the curvature of the main shaft 31, the measuring component 1 determines the position where the curvature of the main shaft 31 is the largest in the circumferential direction, and straightens the position where the curvature is the largest by the straightening component 2 until the straightness and concentricity of the main shaft 31 meet the requirements.
[0033] In some embodiments, the straightening component 2 is placed at the middle position of the main shaft 31 along the axial direction to improve the straightening effect of the main shaft 31.
[0034] In some embodiments, the Dynamo machine 3 includes a body 33, a main shaft 31, and a bushing 32. The bushing 32 is rotatably mounted on the body 33. One end of the main shaft 31 passes through the bushing 32 and is fixedly connected to the bushing 32. The other end of the main shaft 31 is straightened by a straightening device. The rotation of the bushing 32 can drive the main shaft 31 to rotate, thereby enabling the straightening assembly 2 to straighten the position of the main shaft 31 with the greatest curvature.
[0035] In some embodiments, the Dana machine main shaft straightening device further includes a control component, which is capable of determining the straightening force applied by the straightening component 2 to the main shaft 31 based on the curvature measured by the measuring component 1. The control component is electrically connected to the measuring component 1 and the straightening component 2. The control component obtains the curvature data measured by the measuring component 1, analyzes it, determines the position of maximum curvature on the main shaft 31 and the straightening force that the straightening component 2 should apply, and controls the rotation of the main shaft 31 so that the straightening component 2 can apply the straightening force to the position of maximum curvature on the main shaft 31, thereby improving the straightening effect of the main shaft 31.
[0036] See Figure 1 and Figure 2 In some embodiments, during actual production, the end of the main shaft 31 furthest from the Dynamo machine 3 has less constraint and is more prone to deformation. Therefore, the measuring component 1 includes a first measuring element 11, which is configured to measure the curvature of the end of the main shaft 31 furthest from the Dynamo machine 3. The straightening component 2 can straighten the main shaft 31 based on the curvature measured by the first measuring element 11. By measuring the curvature of the main shaft 31 of the Dynamo machine 3 through the first measuring element 11, the measured curvature can be used as the basis for the straightening component 2 to straighten the main shaft 31, determine the magnitude of the straightening force that should be applied to the main shaft 31, and straighten the main shaft 31 by the straightening component 2 to improve the straightness and concentricity of the main shaft 31.
[0037] In some embodiments, the first measuring element 11 is a dial indicator. During the measurement of the curvature of the main shaft 31, the main shaft 31 rotates along the axis, the dial indicator remains stationary, and the dial indicator contacts different positions of the rotating main shaft 31, thereby determining the curvature of the main shaft 31 at different positions.
[0038] In some embodiments, the first measuring element 11 may also be a sensor capable of measuring the curvature of the main shaft 31.
[0039] In some embodiments, the measuring component 1 further includes a second measuring element 12, which is used to measure the curvature of the main shaft 31 after straightening by the straightening component 2. The second measuring element 12 can measure the curvature of the main shaft 31 after straightening by the straightening component 2, thereby verifying whether the straightening effect of the straightening component 2 meets expectations. If the straightening effect does not meet expectations, the straightening force that the straightening component 2 should apply to the main shaft 31 is determined based on the curvature measured by the second measuring element 12, and the straightening component 2 repeatedly straightens the main shaft 31 until the curvature measured by the second measuring element 12 meets the straightening effect.
[0040] In some embodiments, the second measuring element 12 is a dial indicator. During the measurement of the curvature of the main shaft 31, the main shaft 31 rotates along the axis, the dial indicator remains stationary and its contacts come into contact with different positions of the rotating main shaft 31, thereby determining the curvature of the straightened main shaft 31.
[0041] In some embodiments, the second measuring element 12 may be a sensor capable of measuring the curvature of the main shaft 31.
[0042] In some embodiments, the straightening assembly 2 includes a support member 21 and a straightening member 22. The support member 21 supports the main shaft 31, and the straightening member 22 applies a straightening force to the main shaft 31 to straighten it. The direction of the straightening force is opposite to the direction of the supporting force applied by the support member 21 to the main shaft 31. The support member 21 can effectively support the main shaft 31, ensuring that the main shaft 31 remains stable during the straightening process and reducing deformation and damage to the main shaft 31 during the straightening process. The straightening member 22 can apply a straightening force to the main shaft 31 to straighten it. Since the direction of the straightening force is opposite to the supporting force, it can ensure the stability of the force on the main shaft 31 during the straightening process, thereby ensuring the straightening effect of the main shaft 31.
[0043] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The straightening component 22 is disposed within the support component 21 and can apply an upward straightening force to the main shaft 31. The support component 21 has a through hole 215 through which the main shaft 31 passes, and the support component 21 can apply a downward supporting force to the main shaft 31. By placing the straightening component 22 within the support component 21, not only can the straightening component 22 be effectively supported, but it can also facilitate the placement of the straightening component 22 and the handling of the straightening assembly 2. The through hole 215 allows the main shaft 31 to pass through the support component 21, ensuring that the main shaft 31 and the support component 21 cooperate. The support component 21 above the through hole 215 can apply a downward supporting force to the main shaft 31, thereby ensuring the stability of the main shaft 31 under force during the straightening process.
[0044] In some embodiments, the straightening member 22 is disposed in the middle position within the support member 21 to ensure that the straightening force and the support force on the main shaft 31 are balanced.
[0045] In some embodiments, the straightening component 22 is a jack.
[0046] See Figure 1 and Figure 2 In some embodiments, the second measuring element 12 and the straightening element 22 are respectively disposed above and below the main shaft 31 along the radial direction of the main shaft 31. After the second measuring element 12 measures the curvature of the main shaft 31, the straightening element 22 located below the second measuring element 12 measures the main shaft 31, ensuring the accuracy of the curvature of the main shaft 31 and the applied straightening force, reducing the straightening error of the main shaft 31, and ensuring the accuracy and reliability of the straightening of the main shaft 31; the spacing between the second measuring element 12 and the straightening element 22 can avoid interference between the two and ensure the accuracy of the second measuring element 12 and the straightening element 22.
[0047] In some embodiments, see Figure 3 The support member 21 also includes an opening 216, through which the second measuring member 12 is disposed on the support member 21 and can measure the curvature of the main shaft 31. The opening 216 on the support member 21 ensures that the second measuring member 12 is in contact with the main shaft 31, thereby enabling effective measurement of the curvature of the main shaft 31.
[0048] See Figures 1 to 5 In some embodiments, the measuring assembly 1 further includes a mounting bracket 13 and a locking member 14. The mounting bracket 13 is disposed on the support member 21, and the locking member 14 is used to lock the second measuring member 12 onto the mounting bracket 13. The mounting bracket 13 and the locking member 14 ensure that the second measuring member 12 is stably mounted on the support member 21, thus ensuring the accuracy and precision of the measurement by the second measuring member 12.
[0049] See Figures 1 to 5 In some embodiments, the support member 21 includes a base plate 211, two first side plates 212, two second side plates 213, and a top plate 214. A straightening member 22 is provided on the base plate 211. The two first side plates 212 are radially spaced on both sides of the base plate 211 along the main shaft 31, and the two second side plates 213 are axially spaced on both sides of the base plate 211 along the main shaft 31. The top plate 214 connects the two first side plates 212 and is radially spaced from the base plate 211 along the main shaft 31. An opening 216 for the second measuring member 12 to pass through is provided on the top plate 214. A through hole 215 for the main shaft 31 to pass through is formed between the top plate 214, the first side plates 212, and the second side plates 213. This support member 21 has a simple structure and achieves lightweight design, making the handling of the straightening device easier.
[0050] In some embodiments, the support member 21 is made of steel plate, and the thickness of the material is sufficient to ensure the stability of the mechanical strength of the support member 21 during the straightening process and to prevent deformation.
[0051] In some embodiments, see Figure 5 There are two top plates 214, which are spaced apart along the axial direction of the main shaft 31 on both sides of the second measuring member 12. An opening 216 is formed between the two top plates 214 and the two first side plates 212 for the second measuring member 12 to pass through.
[0052] See Figure 1 and Figure 2 In some embodiments, the straightening assembly 2 further includes a first shim 23, which is disposed between the main shaft 31 and the support member 21 to ensure that the main shaft 31 and the support member 21 are in contact. The first shim 23 ensures the contact between the main shaft 31 and the support member 21, guarantees the stability of the force between the main shaft 31 and the support member 21, and reduces the risk of damage to the main shaft 31.
[0053] In some embodiments, the shape of the first pad 23 matches the shape of the main shaft 31 to ensure that the main shaft 31 and the first pad 23 fit together.
[0054] See Figure 1 and Figure 2 In some embodiments, the straightening assembly 2 further includes a second shim 24, which is disposed between the straightening member 22 and the main shaft 31 so that the main shaft 31 fits against the straightening member 22. The placement of the second shim 24 ensures the fit between the main shaft 31 and the straightening member 22, guarantees the stability of the force between the main shaft 31 and the straightening member 22, and reduces the risk of damage to the main shaft 31.
[0055] In some embodiments, the shape of the second pad 24 matches the shape of the main shaft 31 to ensure that the main shaft 31 and the second pad 24 fit together.
[0056] In some embodiments, the Dana machine main shaft straightening device further includes a bracket 4 for supporting the straightening assembly 2. The bracket 4 can effectively support the straightening assembly 2 and ensure the relative fit between the straightening assembly 2 and the main shaft 31.
[0057] In some embodiments, the height of the bracket 4 is adjustable.
