[0023] like Figure 1-4 As shown, the utility model provides a technical solution: a tubular neutral borosilicate glass opening melting and sealing device, comprising a base 1, a melting and sealing machine 2 is fixedly connected to the top of the base 1, and the melting and sealing machine 2 is connected to a melting gun 3, a bottom plate 5 is provided on the top of the base 1, the bottom plate 5 is located on the front side of the melting and sealing machine 2, a cylindrical fixing seat 7 is provided on the bottom plate 5, and a socket is provided on the top of the fixing seat 7, a fixing mechanism is provided in the socket, two melting guns 3 are provided, and hoses are connected between the two melting guns 3 and the melting and sealing machine 2, brackets 4 are fixedly connected near the left and right sides of the top of the base 1, the two brackets 4 are L-shaped, and the two melting guns 3 are respectively fixedly connected to the two brackets 4 and are symmetrically arranged.

[0024] According to the overall structure of the device, the glass tube is inserted into the jack of the fixing seat 7 and fixed by the fixing mechanism, and then the sealing machine 2 is started, and the two sides of the opening of the glass tube are heated at high temperature by the melting gun 3 to perform sealing.

[0025] like Figure 3 As shown, the fixing mechanism includes three clamping blocks 12, which are all located in the socket and distributed in a circular array.

[0026] The movable tube 8 is rotated, and under the action of the threaded connection, the movable tube 8 moves downward, and the clamping block 12 is pushed to move toward the glass tube and closely adhere to the glass tube through the fitted inclined surfaces, thereby fixing the glass tube to prevent the glass tube from shaking during the sealing process, affecting the sealing point and making the opening incompletely sealed. Moreover, the movable tube 8 is moved downward by different distances by rotating different circles, and then the clamping block 12 is moved by different distances, so it can be suitable for the sealing of glass tubes with different diameters. The clamping block 12 stretches the telescopic spring during the clamping of the glass tube. After the glass tube is relaxed, the clamping block 12 is pulled to reset by the telescopic spring.

[0027] like Figure 2 As shown, the top of the base plate 5 is located at the rear side of the fixed seat 7 and is fixedly connected to a motor 9. The base plate 5 is hollow, and the output shaft of the motor 9 extends into the base plate 5 and is fixedly connected to a gear 10. The bottom of the fixed seat 7 extends into the base plate 5 and is movably connected to the base plate 5. A plurality of gear blocks are fixedly connected to the peripheral side of the fixed seat 7, and the gear blocks are meshed with the gears 10.

[0028] The motor 9 drives the gear 10 to rotate, and the gear 10 drives the fixing seat 7 to rotate through the tooth block, thereby driving the glass tube to rotate, so that the surface of the glass tube is evenly heated, the melting degree of the glass tube opening is uniform, and the gap is avoided after sealing.

The bottom plate 5 is slidably connected in the slide groove through the slide rail 6. A screw rod 11 is threadedly connected on the bottom plate 5, and a positioning hole matching the screw rod 11 is provided at the bottom of the slide groove.

[0030] The bottom plate 5 can be moved outward by the slide rail 6, so that the fixing seat 7 and the glass tube can be moved away from the melting gun 3, which is convenient for removing and replacing the sealed glass tube, avoiding high-temperature burns caused by contact between the hands and the muzzle of the melting gun 3, and improving safety.

[0031] like Figure 4 As shown, the two brackets 4 each include an L-shaped movable rod 402 and a fixed tube 401, the fixed tube 401 is vertically fixedly connected to the base 1, and the movable rod 402 is inserted into the fixed tube 401, a plurality of linearly arranged slots are provided on the outer side of the movable rod 402, a U-shaped movable plate 403 is movably connected to the top of the fixed tube 401, and a block 404 is fixedly connected to the inner side of the movable plate 403, a connecting shaft 405 is movably connected between the movable plate 403 and the fixed tube 401, and a torsion spring is sleeved on the outer side of the connecting shaft 405, and the cross-sections of the plurality of slots and the block 404 are all right-angled triangles, and one of the right-angled sides is horizontally set.

When the height of the movable rod 402 needs to be adjusted, the movable rod 402 can be directly pulled upward, and the clamping block 404 and the inclined surface of the clamping slot are squeezed to make the clamping block 404 directly move out of the clamping slot, and at the same time drive the movable plate 403 to deflect and compress the torsion spring. As the movable rod 402 is pulled to a specified height, the movable plate 403 is reset under the action of the torsion spring, so that the clamping block 404 is inserted into the adjacent clamping slot, and the clamping block 404 is directly fitted with the horizontal surface of the clamping slot for support and fixation, or the movable plate 403 is flipped outward to separate the clamping block 404 from the clamping slot, so that the movable rod 402 moves down to a specified height, and the movable plate 403 is released. The movable plate 403 is reset under the action of the torsion spring, so that the clamping slot and the clamping block 404 are clamped and fixed.

After the sealing is completed, turn off the motor 9 and the sealing machine 2, rotate the screw 11, move the bottom plate 5 forward, make the glass tube away from the melting gun 3, and rotate the movable tube 8 in the opposite direction to loosen the glass tube, and then the glass tube can be removed. During use, when the lengths of the glass tubes are different and the opening heights are different, flip the movable plate 403 outward to separate the block 404 from the slot, so that the movable rod 402 can be moved upward to adjust the height of the melting gun 3.
