After placing the quartz tube, the fastening screw rod is rotated, and the fastening screw rod is used to push the clamping plate to fix the quartz tube; by setting a servo motor, a conveyor belt, conveying rollers, an electric telescopic rod, and a radiator fan, when the servo motor is started, the conveying rollers and the conveyor belt are driven by the servo motor to rotate until the quartz tubes are transported one by one below the welding head. Then the electric telescopic rod is started, and the welding head is used for sealing. After welding one quartz tube, with the transmission of the conveyor belt, the welded quartz tube is conveyed to the radiator fan, and the radiator fan is used for heat dissipation, so that it can be quickly cooled and taken. When the sealing machine of this design seals the quartz tube, there is no need for manual holding, which not only greatly improves the safety performance but also reduces potential safety hazards.

[0004] The inventor found in daily work that from the attached drawings of the above automatic quartz tube sealing machine, the shape of the clamping plate is rectangular, while the quartz tube is circular. This will cause the clamping plate not to fit the outer wall surface of the quartz tube when clamping and fixing the quartz tube, resulting in poor clamping effect. Summary of the Utility Model

However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0024] The following specifically describes the specific settings and functions of its clamping device 2 and rotating device 3.

[0025] In this embodiment: a clamping device 2 is provided on the surface of the base 1. The clamping device 2 includes a rotating column 21, the rotating column 21 is rotatably connected to the surface of the base 1, and a plurality of support rods 22 are annularly distributed on the outer wall surface of the rotating column 21. One end of the plurality of support rods 22 away from the rotating column 21 is fixedly installed with a U-shaped seat 23.

[0026] In this embodiment: the setting of the rotating column 21 plays the role of driving the support rods 22 and the U-shaped seat 23 to rotate, and the setting of the U-shaped seat 23 plays the role of supporting the quartz tube.

[0027] Specifically, fixing plates 24 are fixedly installed on the top surfaces of the outer walls on both sides of the U-shaped seat 23. A threaded rod 25 is rotatably connected between the two fixing plates 24. A runner 26 is fixedly installed on the surface of the threaded rod 25. The threads on the surface of the threaded rod 25 are reverse threads centered on the runner 26.

[0028] In this embodiment: the setting of the runner 26 plays the role of driving the threaded rod 25 to rotate.

[0029] Specifically, a slide bar 27 is fixedly installed between the two fixing plates 24. Two movable plates 28 are threadedly connected to the surface of the threaded rod 25. An arc-shaped clamping ring 29 is fixedly installed on the bottom surface of the movable plate 28. The setting of the arc-shaped clamping ring 29 plays the role of clamping and limiting the quartz tube.

[0030] In this embodiment: A rotating device 3 is provided on the bottom surface of the rotating column 21. The rotating device 3 includes a rotating rod 31. The rotating rod 31 is fixedly installed on the bottom surface of the rotating column 21, and a gear 32 is fixedly installed on the outer wall surface of the rotating rod 31. When it is necessary to weld the next quartz tube after welding one quartz tube, first start the electric telescopic rod 37. The start of the electric telescopic rod 37 drives the sliding plate 34 to move inside the groove 33. The movement of the sliding plate 34 inside the groove 33 drives the rack 35 to move. The rack 35 moves and meshes with the gear 32, thereby causing the gear 32 to rotate. The rotation of the gear 32 drives the rotating rod 31 to rotate. The rotation of the rotating rod 31 drives the rotating column 21 to rotate. The rotation of the rotating column 21 drives the support rod 22 to rotate. The rotation of the support rod 22 drives the U-shaped seat 23 to rotate. When the U-shaped seat 23 rotates to directly below the welding torch 6, just turn off the electric telescopic rod 37. Through the cooperation of the above structures, after the device seals one quartz tube, it can process the next quartz tube without releasing the clamping and limiting of the sealed quartz tube, thereby improving the sealing efficiency of the device.

[0031] Specifically, a groove 33 is formed on the bottom surface of the base 1. A sliding plate 34 is slidably connected inside the groove 33. A rack 35 is fixedly installed on the surface of the sliding plate 34. The rack 35 and the gear 32 mesh with each other.

[0032] In this embodiment: The setting of the rack 35 serves to drive the rotation of the gear 32.

[0033] Specifically, a support plate 36 is fixedly installed on the bottom surface of the base 1. An electric telescopic rod 37 is fixedly installed on the surface of the support plate 36. The output end of the electric telescopic rod 37 is fixedly connected to the sliding plate 34.

[0034] In this embodiment: The setting of the electric telescopic rod 37 serves to drive the sliding plate 34 to move inside the groove 33.

[0035] Working principle: By setting the clamping device 2, when the device is needed, first place the quartz tube inside the U-shaped seat 23, and then rotate the rotating wheel 26. The rotation of the rotating wheel 26 drives the rotation of the threaded rod 25. Since the threads on the surface of the threaded rod 25 are reverse threads centered on the rotating wheel 26, when the rotating wheel 26 drives the threaded rod 25 to rotate, the two movable plates 28 connected by the threads on its surface will move towards each other on the surface of the sliding rod 27. The movement of the two movable plates 28 towards each other on the surface of the sliding rod 27 drives the two arc-shaped clamping rings 29 to move towards each other. The movement of the two arc-shaped clamping rings 29 towards each other clamps and fixes the quartz tube. After the quartz tube is clamped and fixed, plug a quartz column at the end of the quartz tube, and then start the cylinder 5. The start of the cylinder 5 drives the welding torch 6 to move downward. The downward movement of the welding torch 6 seals the quartz tube. Through the cooperation of the above structures, the arc-shaped clamping ring 29 can clamp and fix the quartz tube. At the same time, the arc-shaped clamping ring 29 has a certain curvature in its outer shape, so that when the arc-shaped clamping ring 29 clamps and fixes the quartz tube, it can fit more closely to the outer wall of the quartz tube, and the clamping effect is better. When it is necessary to weld the next quartz tube after welding one quartz tube, first start the electric telescopic rod 37. The start of the electric telescopic rod 37 drives the sliding plate 34 to move inside the groove 33. The movement of the sliding plate 34 inside the groove 33 drives the rack 35 to move. The movement of the rack 35 meshes with the gear 32, thereby causing the gear 32 to rotate. The rotation of the gear 32 drives the rotation of the rotating rod 31. The rotation of the rotating rod 31 drives the rotation of the rotating column 21. The rotation of the rotating column 21 drives the rotation of the support rod 22. The rotation of the support rod 22 drives the U-shaped seat 23 to rotate. When the U-shaped seat 23 rotates to directly below the welding torch 6, just turn off the electric telescopic rod 37. Through the cooperation of the above structures, after the device seals one quartz tube, it can process the next quartz tube without releasing the clamping and limiting of the sealed quartz tube, thereby improving the sealing efficiency of the device.
