[0028] like Figure 1-Figure 4 As shown, a borosilicate glass tube feeding device comprises:

[0029] A bottom support frame 1, two support frames 2 are arranged on the top in mirror symmetry on the left and right sides, the support frames 2 are rotatably connected with a rotating shaft 3, and a circulation disk 4 is fixedly connected to the end of each rotating shaft 3, and three semicircular grooves 5 are arranged on the edge of each circulation disk 4 with equal circumference;

[0030] A limit frame 6 is fixedly connected to the top of the bottom support frame 1, and the limit frame 6 is spaced outside the two circulation disks 4;

[0031] A power output mechanism 7, arranged on the bottom support frame 1, and drivingly connected to the rotating shaft 3;

[0032] The circulating clamping mechanism 8 is provided with three and clamped on the semicircular groove 5;

[0033] The circulation switching mechanism 9 is fixedly connected to the bottom support frame 1 .

[0034] In this embodiment, each circulating clamping device clamps a glass tube. This device is equipped with an intelligent robotic arm. The intelligent robotic arm grabs the glass tube so that it is clamped by the circulating clamping device. The power is transmitted through the power output mechanism 7, so that the circulating clamping mechanism 8 reciprocates in the semicircular grooves 5 of the two circulating disks 4. When the two circulating disks 4 rotate relative to each other, the circulating switching mechanism 9 is used to guide the circulating clamping mechanism 8 to change its working position in the two circulating disks 4. The clamped glass tube can be processed at the position in between, such as heating and shaping, pressing threads, etc. After the processing is completed, it returns to the position where the glass tube was originally loaded, so that the intelligent robotic arm can unload it.

[0035] As an optional implementation, Figure 1 ,2 As shown in Figure 3, the power output mechanism 7 includes a driving motor 10 fixedly connected to the bottom support frame 1, a first pulley 11 is connected to the main shaft of the driving motor 10, a second pulley 12 is connected to the end of the rotating shaft 3 on one side, a transmission belt 13 is connected between the second pulley 12 and the first pulley 11, a first gear 14 is fixedly connected to the rotating shaft 3 with the second pulley 12 at the tail end, and a second gear 15 is connected to the other rotating shaft 3, and the first gear 14 and the second gear 15 are meshed;

[0036] In this way, the main shaft of the driving motor 10 drives the first pulley 11 to rotate, and the first pulley 11 drives the second pulley 12 to drive one of the rotating shafts 3 to rotate through the transmission belt 13, thereby rotating the first gear 14 and the second gear 15 that are meshed with each other, driving the two circulation disks 4 to rotate relative to each other.

[0037] As an optional embodiment, the first gear 14 and the second gear 15 have the same module, number of teeth and pressure angle;

[0038] In this way, the two circulation disks 4 have the same rotation speed.

[0039] As an optional implementation, both the first gear 14 and the second gear 15 are provided with weight-reducing holes;

[0040] In this way, the operating loads of the first gear 14 and the second gear 15 are reduced.

[0041] As an optional implementation, Figure 1 , 2 As shown in FIG. 3 , the circulating clamping mechanism 8 includes a rod body that fits in the semicircular groove 5, and the front and rear ends of the rod body are respectively fixedly connected with a front limit plate 16 and a rear limit plate 17 for limiting the forward and backward movement of the rod body, and the front limit plate 16 is rotatably connected with an inflatable shaft 18;

[0042] In this way, the inflatable shaft 18 is used to clamp the glass tube from the inside of the glass tube.

[0043] As an optional implementation, Figure 1 , 2 As shown in FIG. 3 , the rear end of the rear limit plate 17 is fixedly connected to a rotary motor 19, and the main shaft of the rotary motor 19 passes through the rear limit plate 17, the rod body and the front limit plate 16 in sequence and is transmission-connected to the inflatable shaft 18;

[0044] In this way, the glass tube clamped on the inflatable shaft 18 can drive the inflatable shaft 18 to rotate along with the rotation of the main shaft of the rotating motor 19.

[0045] As an optional implementation, Figure 4As shown, the cyclic switching mechanism 9 includes a swing rod bracket 20 fixedly connected to the bottom support frame 1, the top of the swing rod bracket 20 is rotatably connected to a L-shaped swing rod 21, the top of the back side of the L-shaped swing rod 21 is fixedly connected to a first fixed shaft 22, the back side of the swing rod bracket 20 is fixedly connected to a second fixed shaft 23, and a tension spring 24 is connected between the first fixed shaft 22 and the second fixed shaft 23;

[0046] Thus, along with the rotation of the circulation disk 4, the circulation clamping mechanism 8 and the tension spring 24 cause the L-shaped swing rod 21 to swing back and forth, and at the same time, the L-shaped swing rod 21 will also guide the circulation clamping mechanism 8 to perform an "8"-shaped circulation motion.

[0047] As an optional implementation, Figure 4 As shown, the swing arm bracket 20 is also fixedly connected to two angle limiting blocks 25, the two angle limiting blocks 25 are distributed in mirror symmetry, and the tops of the two angle limiting blocks 25 are rounded, and the angle limiting blocks 25 are located on the rotation path of the L-shaped swing arm 21;

[0048] In this way, the angle limit block limits the final rotation angle of the L-shaped rocker arm 21, so as to ensure that the circulation clamping mechanism 8 moves smoothly.
