Description

Technical Field

[0001] This utility model relates to the field of quartz product manufacturing technology, and in particular to a device for rotating tapered capillary tubes. Background Technology

[0002] The capillary tapering machine is a commonly used machine for tapering capillary tubes. The capillary tapering machine clamps both ends of the capillary tube, heats the middle with a flame, and moves the clamped ends outward to achieve the tapering effect.

[0003] The above solution is the commonly used solution for capillary tapering on the market. However, the above solution has defects and shortcomings: the capillary tapering adopts a horizontal tapering method, and the capillary is on the same horizontal plane. When the flame is heated, it will soften the capillary. The softened capillary will fall naturally under the influence of gravity. This will cause the tapered head to be biased to one side and not in the center after the capillary tapering is formed, which urgently needs to be improved. Utility Model Content

[0004] To address the aforementioned problems, a device for rotating a tapered capillary tube is provided, aiming to solve the problems existing in the prior art.

[0005] The specific technical solution is as follows:

[0006] A device for rotating a tapered capillary tube includes a capillary tube fixing assembly, two support platforms, two transmission assemblies, and a drive assembly. The two parts of the fixing assembly are respectively sleeved on both ends of the capillary tube. The top surface of the support platform has a groove for the fixing assembly to be inserted. The transmission assembly is disposed at one end of the support platform and is drively connected to the fixing assembly. The two power output ends of the drive assembly are drively connected to the two transmission assemblies respectively.

[0007] The aforementioned rotating tapered capillary device also features the following characteristics: the fixing component includes a first cover and a second cover, with fixing recesses on opposite sides of the first cover and the second cover; the first cover and the second cover interlock to form a cylindrical assembly; a positioning hole is provided on one end face of the first cover; and connecting holes are provided on both the first cover and the second cover. When the first cover and the second cover are interlocked, they can be fixed together by bolts, so that the first cover and the second cover clamp the capillary between them.

[0008] The beneficial effects of the above scheme are as follows: the first cover and the second cover are fastened to both ends of the quartz tube, clamping the quartz tube. At this time, rotating the first cover and the second cover will drive the quartz tube to rotate accordingly.

[0009] The aforementioned rotating tapered capillary device also has the following feature: the cross-section of the fixing recess on the first cover is triangular, and the cross-section of the fixing recess on the second cover is rectangular.

[0010] The beneficial effects of the above scheme are: when the first cover and the second cover are fastened together, the capillary tube can be clamped, preventing the capillary tube from rotating relative to the first cover and the second cover.

[0011] The aforementioned rotating tapered capillary device also has the following feature: the transmission assembly includes a mounting body, an extension cylinder, and a transmission gear. The mounting body is disposed on one end face of the support platform, the extension cylinder is disposed on the side of the mounting body facing the capillary, the transmission gear is sleeved on the extension cylinder, and a positioning body that can be inserted into the positioning hole is provided on the side of the transmission gear facing the capillary. At this time, driving the transmission gear to rotate can drive the entire assembly and the capillary to rotate.

[0012] The beneficial effects of the above scheme are as follows: the mounting body is used to connect with the support platform, the extension cylinder is used to install the transmission gear, the side wall of the transmission gear is connected to the whole, and when the transmission gear rotates, it can drive the whole to rotate, which can drive the quartz tube to rotate.

[0013] The aforementioned rotating tapered capillary device also has the following feature: the driving component includes a toothed bar and a power unit; the toothed bar is disposed on one side of the support platform; both ends of the toothed bar are respectively engaged with two transmission gears; and the toothed bar is driven by the power unit.

[0014] The beneficial effects of the above scheme are: the power unit is used to output power, and the gear bar can transmit power to two transmission gears at the same time, so that the two ends of the capillary tube rotate in the same direction and at the same speed.

[0015] The aforementioned rotating tapered capillary device also includes a cover, which is detachably mounted on the top surface of the support platform. When the cover is closed on the support platform, the cover prevents the entire assembly from detaching from the groove.

[0016] The beneficial effects of the above solution are: the cover can restrict the overall displacement, so that the whole can only rotate in the groove.

[0017] In summary, the beneficial effects of this scheme are:

[0018] In the rotating tapered capillary tube device provided by this utility model, the two ends of the capillary tube are restricted to two support platforms by a fixing component, and the capillary tube is driven to rotate at a uniform speed by a driving component and a transmission component to avoid sagging due to gravity during tapering. The rotating tapered capillary tube device provided by this utility model has the effect of keeping the pulled-out cone tip on the axis. Attached Figure Description

Figures 1-4 As shown, the device for rotating tapered capillary tube provided in this embodiment includes a capillary tube fixing component, two support platforms 1, two transmission components and a drive component. The two parts of the fixing component are respectively sleeved on both ends of the capillary tube. The top surface of the support platform 1 is provided with a groove for the fixing component to be inserted. The transmission component is disposed at one end of the support platform 1 and is connected to the fixing component in a transmission manner.

[0028] It should be noted that the two support platforms 1 are spaced apart, and both support platforms 1 are driven by a tapered machine.

[0029] In the above embodiment, the fixing component includes a first cover 2 and a second cover 3. Fixing recesses are provided on the opposite sides of the first cover 2 and the second cover 3. The first cover 2 and the second cover 3 are interlocked to form a cylindrical whole. A positioning hole is provided on one end face of the first cover 2. Both the first cover 2 and the second cover 3 are provided with connecting holes. When the first cover 2 and the second cover 3 are interlocked, they can be fixed by bolts, so that the first cover 2 and the second cover 3 clamp the capillary between them.

[0030] In the above embodiment, the cross-section of the fixing recess on the first cover 2 is triangular, and the cross-section of the fixing recess on the second cover 3 is rectangular.

[0031] In the above embodiment, the transmission assembly includes a mounting body 4, an extension cylinder 5, and a transmission gear 6.
