The bevel gear set 54 is used to rotate the fixing rod 53 to drive one of the bevel gears, and to drive the other bevel gear through one of the bevel gears, and to drive the support member 55 to rotate through the rotation of the other bevel gear. The top of the support member 55 is used to support the outer surface of the glass tube to prevent the tail of the glass tube from collapsing after burning, so that the clamping device 13 can stretch the glass tube more accurately to ensure that the tail of each glass tube can be stretched.

[0047] The complete working principle and steps of the above embodiment are as follows:

[0048] refer to Figures 1 to 5 As shown, when the anti-re-overflow gallium indium tin thermometer production equipment is in the initial state, the output end of the electric push rod 11 is in a contracted state, the output end of the clamping device 13 is in an expanded state, the first spring 22 and the second spring 25 are in a naturally relaxed state, and the cutting knife 27 is in a ring-shaped expanded state;

[0049] When the device is used to produce the anti-re-overflow gallium indium tin thermometer, the electric roller 14 and the heating device 16 are first started, and the glass tube to be processed is placed on the outer surface of the transmission wheel 15. As the electric roller 14 starts to rotate, it will drive the transmission wheel 15 fixedly connected to the outer surface of the electric roller 14 to rotate at the same time. When the transmission wheel 15 rotates, it will drive the glass tube on the outer surface to be transported. At this time, the heating device 16 can heat the tail of the glass tube. When the glass tube is transported to the specified position, the electric push rod 11 will drive the connecting piece 12 and the clamping device 13 to move backward at the same time, and when the connecting piece 12 moves backward, it will drive the top sliding piece 21 and the left extruding piece 24 to move at the same time. As the sliding piece 2 When the guide member 23 moves, it will drive the guide member 23 fixedly connected to the rear end of the sliding member 21 to move at the same time. When the guide member 23 moves backward, it will drive the first rotating member 26 inside and the cutting knife 27 at the rear end to move at the same time. At this time, the outer surface of the glass tube will slide into the inside of the guide member 23. At this time, the output end of the clamping device 13 will clamp the tail of the glass tube, and the guide member 23 will then move backward and fit the front side of the first fixing member 2. At this time, the guide member 23 is blocked by the front end of the first fixing member 2 and will not move forward, and the first rotating member 26 and the cutting knife 27 will also stop moving. At this time, when the connecting member 12 moves backward, the inner side of the top of the connecting member 12 will slide on the outer surface of the sliding member 21. The rear end of the first spring 22 is fixedly connected to the front side of the connecting member 12. As the connecting member 12 moves, the first spring 22 will move to a stretched state, and the connecting member 12 will also drive the extrusion member 24 fixedly connected to the left side of the connecting member 12 to move backward. Since the rear side of the extrusion member 24 is inclined, as the extrusion member 24 moves backward, the arc strip 261 will slide upward on the upper surface of the extrusion member 24, and when the arc strip 261 slides upward, it will slide upward on the inner side of the square hole of the limit strip 231. As the arc strip 261 slides upward, the second spring 25 will be moved to a compressed state. At this time, when the arc strip 261 moves online, it will drive the first rotating member 26 to rotate at the same time. When the rotating member 26 rotates, it will cause the cutting knife 27 to slide in the U-shaped groove on the surface of the first rotating member 26. Since the front side of the cutting knife 27 is slidably connected to the hexagonal groove of the guide member 23, as the first rotating member 26 drives the cutting knife 27 to move, the cutting knife 27 moves toward the center of the guide member 23. At this time, the inner side of the cutting knife 27 can perform a circular cut on the tail end of the glass tube to avoid wire drawing on the glass tube and improve the overall quality of the product. In addition, since the cutting knife 27 is cut in a circular shape, the accuracy of the cutting path can be consistent, avoiding cut marks caused by traditional straight line cutting, and the circular cutting can reduce burrs and unevenness, which helps to improve the appearance quality of the product.

[0050] When the tail end of the glass tube is cut off, the output end of the electric push rod 11 drives the connecting member 12 and the clamping device 13 to move forward at the same time. The clamping device 13 will automatically loosen when driving the waste glass tube to move forward, so that the waste glass will fall into the waste groove opened inside the front side of the workbench 1, and the connecting member 12 will drive the sliding member 21 and the extruding member 24 to move backward at the same time when moving backward. As the sliding member 21 moves backward, the first spring 22 in a stretched state will drive the sliding member 21 to move forward. When the sliding member 21 moves forward, it will drive the guide member 23, the first rotating member 26 and the cutting knife 27, and the first rotating member 26 and the cutting knife 27 will move forward. A rotating member 26 will drive the arc strip 261 to move backward at the same time, and the outer surface of the bottom of the arc strip 261 will slide out from the inclined surface at the rear end of the extruding member 24. At this time, the second spring 25 in a compressed state will drive the arc strip 261 to slide downward on the inner side of the square hole of the limiting strip 231. As the arc strip 261 slides downward, it will drive the first rotating member 26 to rotate in the opposite direction. When the first rotating member 26 rotates in the opposite direction, it will prompt the cutting knife 27 to move in the opposite direction in the U-shaped groove of the first rotating member 26, prompting the cutting knife 27 to move away from the center of the guide member 23, so that the cutting knife 27 returns to its initial state.

[0051] refer to Figure 6 and Figure 7 As shown, when the anti-re-overflow gallium indium tin thermometer production equipment is in the initial state, the rear end of the extrusion rod 3 has not yet been fitted with the left end of the sliding rod 34, the outer surface of the bottom of the first gear 32 is meshed with the rear end of the upper surface of the first rack 33, the second rotating member 35 is in a naturally relaxed state, and the bottom of the second rotating member 35 is not fitted with the outer surface of the glass tube;

[0052] As the connecting member 12 moves backward, the extrusion rod 3 fixedly connected to the left side of the connecting member 12 is driven to move simultaneously, and when the extrusion rod 3 moves backward, it contacts the front side of the sliding rod 34 and pushes the sliding rod 34 backward, and when the sliding rod 34 moves backward inside the front side of the first fixing member 2, the third spring 36 is moved to a compressed state, and as the sliding rod 34 moves backward, the first rack 33 fixedly connected to the rear end of the sliding rod 34 is driven to move simultaneously, and when the first rack 33 moves backward, it causes the first gear 32 to rotate clockwise on the outer surface of the second fixing member 31. Since the right side of the first gear 32 is fixedly connected to the top of the second rotating member 35, On the left side of the part, as the first gear 32 rotates clockwise, the second rotating member 35 is driven to rotate simultaneously, so that the bottom of the second rotating member 35 can fit the outer surface of the top of the glass tube and push the glass tube to the side close to the rear end of the workbench 1. Since the bottom of the second rotating member 35 is made of soft rubber, it will not cause damage to the glass tube when it contacts the outer surface of the glass tube. When the second rotating member 35 pushes the glass tube to the side close to the rear end of the workbench 1, each glass tube can be cut at the same position after being squeezed, which can ensure the precision and accuracy of the glass tube during the stretching process and avoid inconsistent appearance caused by different positions of the glass tubes.

[0053] When the glass tube is processed, the connecting member 12 drives the extruding rod 3 to move forward, and the extruding rod 3 moves forward and is separated from the front end of the sliding rod 34. At this time, the third spring 36 in a compressed state drives the sliding rod 34 to move forward, and the sliding rod 34 moves forward and drives the first rack 33 to move at the same time. As the first rack 33 moves forward, the first gear 32 rotates counterclockwise. When the first gear 32 rotates counterclockwise, the second rotating member 35 rotates at the same time, causing the bottom of the second rotating member 35 to separate from the contact with the outer surface of the glass tube, so that the glass tube can continue to be transmitted to the left.

[0054] refer to Figure 8 and Fig. 9 As shown, when the anti-re-overflow gallium indium tin thermometer production equipment is in the initial state, the fourth spring 41 is in a naturally relaxed state, the rear side of the glass mold 42 has not yet been fitted with the front side of the top of the limiting rod 43, and the outer surface of the front side of the third rotating member 44 has not yet been fitted with the arc surface of the extrusion block 45;

[0055] When the glass tube is processed, it will be transmitted to the left through the transmission wheel 15. When the transmission wheel 15 rotates, it will drive the third rotating member 44 fixedly connected to the front side of the transmission wheel 15 to rotate at the same time. When the third rotating member 44 rotates, the outer surface of the front side of the third rotating member 44 will squeeze the arc surface of the extrusion block 45, and push the extrusion block 45 backward. As the extrusion block 45 moves backward, it will drive the glass mold 42 fixedly connected to the top right side of the extrusion block 45 to move simultaneously. When the glass mold 42 slides backward on the inner side of the top of the third fixed member 4, it will move the fourth spring 41 into a stretched state. At this time, the glass mold 42 moves forward to squeeze the tail of the glass tube, so that the tail of the glass tube forms a uniform and required shape when it is squeezed, thereby improving the overall accuracy of the product. When the glass mold 42 moves backward, it fits against the top of the front side of the limiting rod 43. The limiting rod 43 can limit the distance that the glass mold 42 moves backward to prevent the glass mold 42 from excessively squeezing the tail of the glass tube.

[0056] As the third rotating member 44 continues to rotate, the outer surface of the front side of the third rotating member 44 will be out of contact with the arc surface of the extrusion block 45. At this time, the fourth spring 41 in a stretched state will drive the glass mold 42 to move forward, so that the inner side of the rear end of the glass mold 42 is out of contact with the tail of the glass tube, and the rear side of the glass mold 42 is out of engagement with the outer surface of the front side of the limiting rod 43.

[0057] refer to Fig.10 and Fig.11 As shown, before the glass tube is processed, the bottom of the tail end of the glass tube will fit against the outer surface of the top of the support member 55 to prevent the tail end of the glass tube from collapsing after burning, so that the clamping device 13 can clamp the glass tube more accurately and ensure that the tail end of each glass tube can be clamped. When the connecting member 12 moves backward, it will drive the connecting rod 5 fixedly connected to the bottom of the connecting member 12 to move at the same time. When the connecting rod 5 moves backward, it will drive the second rack 51 to move at the same time. When the second rack 51 moves forward, it will mesh with the outer surface of the second gear 52 and drive the second gear 52 to rotate. When the second gear 52 rotates, it will drive the fixing rod 53 to rotate at the same time. When the fixing rod 53 rotates, it will drive the bevel gear set 54 fixedly connected to the right end of the fixing rod 53 to rotate at the same time. As the bevel gear set 54 rotates, it will drive the support member 55 to rotate at the same time, causing the top of the support member 55 to break away from the fit with the tail end of the glass tube, so as to prevent the support member 55 from affecting the clamping device 13 to clamp the glass tube.

[0058] When the glass tube is processed, the connecting member 12 will drive the connecting rod 5 to slide forward, and when the connecting rod 5 slides forward, it will drive the second rack 51 to move at the same time. As the second rack 51 moves forward, it will prompt the second gear 52 to rotate in the opposite direction. When the second gear 52 rotates in the opposite direction, it will drive the bevel gear set 54 to rotate at the same time through the fixing rod 53. When the bevel gear set 54 rotates in the opposite direction, it will prompt the support member 55 to return to a vertical state, so that the top of the support member 55 can support the glass tube again.
