[0043] Please refer to Figures 5 to 6, several forming parts 5 are formed in two columns and are respectively installed on both sides of the upper surface of the turntable 31. Multiple arrangement methods can also be adopted according to requirements. The forming part 5 includes a body 51 and a receiving rod 52 installed in the body 51. The body 51 has an installation hole 511 penetrating its upper and lower surfaces, and the installation hole 511 is located at its central position. The body 51 with the installation hole 511 vertically penetrates the turntable 31 downward. A receiving rod 52 is installed in the installation hole 511.

There is a gap 54 between the forming die 56 and the installation hole 511. The gap 54 is used to place the glass tube. Secondly, several communication holes 55 are provided between the gap 54 and the receiving hole 521 to connect them. Different shaped forming blocks can be replaced at the top of the forming die 56 according to requirements, so that the glass tube can be processed into different shapes according to requirements.

[0044] There is also a cooling cavity 57 in the body 51. The cooling cavity 57 surrounds the receiving hole 521. A pair of flow holes 58 extend from the inner wall of the cooling cavity 57 to the outside of the body 51. The flow holes 58 are used for cooling liquid to flow through. The cooling liquid enters the cooling cavity 57 through the flow holes 58 to cool the glass tube loaded in the receiving hole 521, and then is discharged through the other flow hole 58.

[0045] There is a docking ring 512 at the top of the body 51. The docking ring 512 surrounds the installation hole 511, and its outer surface forms a thread. A fastener 59 is screwed outside the docking ring 512. The fastener 59 can move downward along the thread of the docking ring 512. The fastener 59 is recessed inward from its lower surface and a pressing block 591 is received inside. Sealing rings 592 are installed at both the upper and lower ends of the pressing block 591 to isolate the air communication between the installation hole 511 and the outside. When locking is required, the fastener 59 is rotated. The fastener 59 presses the pressing block 591, and the pressing block 591 applies pressure to the sealing ring 592. The sealing ring 592 deforms, and its outer surface abuts against the glass tube located in the gap 54, and a sealed cavity is formed in the receiving hole 521.

[0046] When the glass tube shaping mechanism, its feeding device and heating equipment of the present invention are in use, the glass tube raw material is manually or by other feeding equipment inserted upside down into the gap 54, so that the shaping die 56 enters the glass tube raw material. The air extraction part 53 extracts air from the accommodation hole 521 to form a vacuum, so that the glass tube raw material is fixed in the gap 54. The motor 21 drives the angle divider 22 to drive the turntable 31 to rotate. The shaping part 5 on one side of the turntable 31 moves to the lower part of the heating furnace (not shown) and then is processed, and the shaping part 5 on the other side is filled. When the glass tube raw material in the shaping part 5 on one side is processed, it then rotates to the filling side to perform the material taking and loading processes.

[0047] The present invention relates to a glass tube shaping mechanism, its feeding device and heating equipment, which has the characteristics of high efficiency. The motor drives the angle divider to drive the turntable to rotate, so as to achieve the purpose of precise feeding. At the same time, through the vacuum adsorption of the glass tube by the air extraction part, the effect of tight fixation is achieved, so that the shaping part enters the heating furnace in batches to complete the processing. At the same time, by using the rotation and movement of the turntable, the material taking and loading processes are carried out on the processed or unprocessed shaping parts, improving the production efficiency.
