Description
Technical Field
[0001] The utility model relates to the technical field of glass tube production, in particular to a rolling support device applicable to a glass tube drawing line. Background Art
[0002] In the glass tube production process, the support and guidance of a high-temperature glass tube are usually completed by a graphite wheel fixed on a substrate. The graphite wheel is installed on a central shaft through bearings at both ends and rotates as the glass tube moves to prevent scratching the glass tube. However, due to the random angular swing of the position of the glass tube on the substrate, the contact between the glass tube and the graphite wheel shifts towards one end, which causes the bearings at both ends of the graphite wheel to bear uneven forces. This not only brings unpredictable increased wear, but also reduces the overall rotational stability, increases the risk of jamming or hysteresis during rotation, and ultimately causes relative sliding between the graphite wheel and the glass tube, thereby scratching the surface of the glass tube.
[0003] In the glass tube production process, the existing rolling support device has the technical problem that due to the random offset of the glass tube, the forces on the bearings at both ends are unbalanced, resulting in unpredictable wear and decreased rotational stability, thereby increasing the risk of scratching the surface of the glass tube. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a rolling support device applicable to a glass tube drawing line to alleviate the technical problems in the related art that due to the random offset of the glass tube, the forces on the bearings at both ends are unbalanced, resulting in unpredictable wear and decreased rotational stability, thereby increasing the risk of scratching the surface of the glass tube.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model lies in:
[0006] The rolling support device provided by the utility model includes:
[0007] A support mechanism, the support mechanism includes at least two support units. Each support unit includes a graphite ball, a bearing set and a rotating shaft. The bearing set is inserted into the graphite ball and sleeved on the rotating shaft arranged in the vertical direction. The support units are arranged on both sides of the glass tube. The graphite ball supports the glass tube through the contact of the upper hemisphere with the glass tube.
[0008] Specifically, the bearing set includes at least one first bearing. The rotating shaft is provided with a stepped surface, and the first bearing abuts against the stepped surface to realize the axial positioning of the graphite ball.
[0009] Specifically, the first bearing is set as a tapered roller bearing, and the contact angle faces the stepped surface.
[0010] Specifically, the first bearing is configured as an angular contact ball bearing, and the contact angle faces the step surface.
[0011] Specifically, it further includes an adjusting mechanism. The adjusting mechanism includes the same number of adjusting units as the support unit and a substrate. Each of the adjusting units is connected to the substrate and is respectively connected to one of the support units. Taking the direction perpendicular to the length direction of the glass tube in the horizontal plane as the first direction. The adjusting unit is used to change the position of the support unit in the first direction to limit the offset of the glass tube in the first direction.
[0012] Specifically, the adjusting unit includes a slider and a slide rail. The slide rail is connected to the substrate, the slider is slidably connected to the slide rail, and the rotating shaft is installed on the slider. The sliding of the slider along the slide rail is used to adjust the position of the support unit.
[0013] Specifically, the adjusting unit further includes a setscrew, and the slider is fixed to the slide rail through the setscrew.
[0014] Specifically, the distance between two adjacent graphite balls in the first direction is used to adjust the support height of the glass tube.
[0015] Specifically, four of the support units form a group to constitute the support mechanism. A plurality of the support mechanisms and the same number of the adjusting mechanisms are evenly distributed along the length direction of the glass tube.
[0016] Specifically, in the length direction of the glass tube, the distance between adjacent support mechanisms is greater than the distance between adjacent support units.
[0017] Based on the above technical solutions, the beneficial effects of the present utility model are analyzed as follows:
[0018] The present utility model provides a rolling support device applicable to a glass tube drawing line, including:
[0019] A support mechanism, the support mechanism includes at least two support units. The support unit includes a graphite ball, a bearing group, and a rotating shaft. The bearing group is inserted into the graphite ball and sleeved on the rotating shaft arranged in the vertical direction. The support units are arranged on both sides of the glass tube. The graphite ball supports the glass tube through the contact of the upper hemisphere with the glass tube.
[0020] In specific applications, at least two of the support units disposed on both sides of the glass tube provide rotational support by simultaneously contacting the glass tube with the upper hemispheres of the graphite balls on both sides. When the glass tube is offset, while the extrusion of the graphite ball on the skewed side by the glass tube increases, the contact point moves upward, accompanied by the separation from the graphite ball on the opposite side. At this time, the graphite ball on the skewed side continues to rotate with the glass tube.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. The components of the embodiments of the present utility model usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.
[0032] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model claimed, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.
[0033] The following will describe in detail some implementation modes of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0034] Existing rolling support devices have the technical problem that due to the random offset of the glass tube, the bearing forces at both ends are unbalanced, resulting in unpredictable wear and a decrease in rotational stability, and further increasing the risk of scratching the surface of the glass tube.
[0035] In view of this, the present utility model provides a rolling support device applicable to a glass tube drawing line, including:
[0036] A support mechanism 100, the support mechanism 100 includes at least two support units 110. The support unit 110 includes a graphite ball 111, a bearing group 112 and a rotating shaft 113. The bearing group 112 is inserted into the graphite ball 111 and sleeved on the rotating shaft 113 arranged in the vertical direction. Support units 110 are arranged on both sides of the glass tube 001. The graphite ball 111 supports the glass tube 001 through the contact of the upper hemisphere with the glass tube 001.
[0037] Based on the above technical solutions, the rolling support device provided by the present utility model can achieve the following technical effects:
[0038] The rolling support device supports the glass tube 001 through at least two graphite balls 111 arranged on both sides of the glass tube 001. Thus, when facing the random offset of the glass tube 001, it can continue to provide support and guidance for the glass tube 001 through the rotation of the unilateral graphite ball 111 and maintain a stable bearing eccentric load, thereby avoiding the unpredictability of bearing wear caused by the random offset of the glass tube 001. It overcomes the technical problems existing in the existing rolling support device, such as uneven force on the two ends of the bearing caused by the random offset of the glass tube, resulting in unpredictable wear and decreased rotational stability, and further increasing the risk of scratching the surface of the glass tube.
[0039] The following combines Figures 1 to 4 to elaborate in detail on the structure and shape of the rolling support device provided in this embodiment:
[0040] In the solution of this embodiment, the bearing group 112 includes at least one first bearing 1121. The rotating shaft 113 is provided with a stepped surface 101, and the first bearing 1121 abuts against the stepped surface 101 to achieve the axial positioning of the graphite ball 111. When facing the random offset of the glass tube 001, the first bearing 1121 always maintains a stable load with predictability, and the rotational stability of the rolling support device can be maintained by regular maintenance or replacement of the first bearing 1121.
[0041] In an alternative solution of this embodiment, the bearing group 112 includes a first bearing 1121 and a second bearing 1122. The first bearing 1121 is inserted at the lower end of the graphite ball 111 and abuts against the stepped surface 101, and is used to bear the gravity of the graphite ball 111 and the glass tube 001 and the horizontal component force of the glass tube 001 on the graphite ball 111. The second bearing 1122 is inserted at the upper end of the graphite ball 111, and is used to bear the horizontal component force of the glass tube 001 on the graphite ball 111, and at the same time assist in fixing the radial position of the graphite ball 111 and the rotating shaft 113. When facing the random offset of the glass tube 001, a stable bearing eccentric load is always maintained, and the force on the first bearing 1121 is greater than that on the second bearing 1122, which is predictable. The rotational stability of the rolling support device can be maintained by regular maintenance or replacement of the first bearing 1121.
[0042] In an alternative solution of this embodiment, the first bearing 1121 is set as a tapered roller bearing, and the contact angle faces the stepped surface 101. The first bearing 1121 can better bear the axial load brought by gravity.
[0043] In an alternative solution of this embodiment, the first bearing 1121 is set as an angular contact ball bearing, and the contact angle faces the stepped surface 101. The first bearing 1121 can better bear the axial load brought by gravity.
[0044] Regarding how the first bearing 1121 and the graphite ball 111 are replaced, specifically:
[0045] The first bearing 1121 is embedded in the graphite ball 111. The graphite ball 111 can be removed by directly lifting it axially upward along the rotation axis 113. Align the central hole of the first bearing 1121 in the new graphite ball 111 with the rotation axis 113, and the new graphite ball 111 will naturally move downward under gravity. When the first bearing 1121 abuts against the step surface 101, the replacement is completed.
[0046] In the solution of this embodiment, an adjustment mechanism 200 is further included. The adjustment mechanism 200 includes the same number of adjustment units 210 as the support unit 110 and a substrate 220. Each adjustment unit 210 is connected to the substrate 220 and is respectively connected to a support unit 110. The direction perpendicular to the length direction of the glass tube 001 in the horizontal plane is defined as the first direction. The adjustment unit 210 is used to change the position of the support unit 110 in the first direction to limit the offset of the glass tube 001 in the first direction. The random offset of the glass tube 001 in the first direction is restricted by the graphite balls 111 on both sides at the same time, improving the forming quality of the glass tube 001.
[0047] In the solution of this embodiment, the adjustment unit 210 includes a slider 211, a slide rail 212, and a setscrew 213. The slide rail 212 is connected to the substrate 220. The slider 211 is slidably connected to the slide rail 212 and is fixed to the slide rail 212 by the setscrew 213. The rotation axis 113 is installed on the slider 211. The sliding of the slider 211 along the slide rail 212 is used to adjust the position of the support unit 110, thereby adjusting the contact point between the graphite ball 111 and the glass tube 001. Since the surface of the graphite ball 111 in contact with the glass tube 001 is an arc surface, when facing the random offset of the glass tube 001, the sliding of the graphite ball 111 along the slide rail 212 can correspond to different offset positions of the glass tube 001.
[0048] When changing the production specifications of the glass tube 001, the diameter and support height of the glass tube 001 also change accordingly. In order to adapt to the production of glass tubes 001 with different specifications, in the solution of this embodiment, the distance between two adjacent graphite balls 111 in the first direction is changed by the adjustment unit 210 to change the contact point between the graphite ball 111 and the glass tube 001, thereby adjusting the support height of the glass tube 001.
[0049] In the solution of this embodiment, four support units 110 form a group to constitute a support mechanism 100 to achieve stable support for the glass tube 001.
[0050] Multiple support mechanisms 100 and the same number of adjustment mechanisms 200 are evenly distributed along the length direction of the glass tube 001. Effective support for the entire length of the glass tube 001 is achieved.
[0051] In the solution of this embodiment, in the length direction of the glass tube 001 , the spacing between adjacent support mechanisms 100 is greater than the spacing between adjacent support units 110 .
[0052] In summary, the specific working process of the rolling support device provided in this embodiment is as follows:
[0053] Here, four supporting units 110 are used as a group to form the supporting mechanism 100 and four adjusting units 210 are used as a group as an example.
[0054] Multiple sets of slide rails 212 are installed in an array along the length direction of the glass tube 001 on the substrate 220. Slide the sliders 211 into one of the slide rails 212 respectively, so that the adjacent sliders 211 are respectively located at both ends of the slide rails 212 and temporarily fixed with the top screws 213. Insert the graphite ball 111 into the rotating shaft 113, and make the first bearing 1121 abut against the step surface 101. Loosen the top screw 213, adjust the spacing between adjacent sliders 211 in the first direction according to the production specifications of the existing glass tube 001 to match the support height of the glass tube 001, and fix it again with the top screw 213. The overall movement of the support mechanism 100 in the first direction is used to adapt to different offset positions of the glass tube 001.
[0055] The support mechanism 100 provides rotation support by contacting the glass tube 001 with the upper hemispheres of the graphite balls 111 on both sides of the glass tube 001. When the glass tube 001 deviates, the glass tube 001 increases the pressure on the graphite balls 111 on the deviated side, and the contact point moves upward, accompanied by the separation from the graphite balls 111 on the opposite side. At this time, the graphite balls 111 on the deviated side continue to rotate with the glass tube 001 and limit the deviation of the glass tube 001.
[0056] When facing the random deviation of the glass tube 001, the rolling support device can maintain a stable bearing unbalanced load. The force on the first bearing 1121 that bears axial load and radial load is always greater than that on the second bearing 1122 that only bears radial load, thereby avoiding the unpredictability of bearing wear caused by the random deviation of the glass tube 001. The rotation stability of the rolling support device is enhanced by targeted strengthening of the first bearing 1121 and increasing the maintenance frequency.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
