Abstract
Description
Technical Field
[0001] This utility model belongs to the field of glass tube sealing technology, specifically a glass tube sealing device for oxyhydrogen flame. Background Technology
[0002] In the field of glass processing, especially in applications such as the manufacture of scientific experimental equipment, the processing of fine glass products, and the assembly of miniature vacuum systems, precise end sealing of glass tubes is often required. The quality of the sealing directly affects the airtightness, mechanical strength, and subsequent performance of the glass products.
[0003] Traditional glass tube sealing methods rely on heating devices such as electric heating wires, high-temperature electric furnaces, or large manually operated gas torches. These methods have many drawbacks in practice, such as uneven heating zones and temperature distribution, which can easily lead to deformation, bubbles, or cracks in the glass tube sealing surface. At the same time, the equipment is bulky, the operation process is complex, and the adjustment is inflexible, requiring high technical skills from operators and making it unsuitable for automation or batch operations. Utility Model Content
[0004] The purpose of this invention is to provide a glass tube sealing device for oxyhydrogen flames, so as to solve at least one aspect of the problems and defects mentioned in the background art.
[0005] A glass tube sealing device for oxyhydrogen flame is provided, comprising a frame, a transverse mechanism on the frame, a rotary sealing mechanism on the transverse mechanism, a limit mechanism on one side of the upper part of the frame, and a bearing mechanism on the side of the frame away from the limit mechanism.
[0006] Furthermore, the lateral movement mechanism includes two electric slide rails, each with an electric slider above it. A rotary sealing mechanism is mounted on each of the two electric sliders. The electric sliders drive the electric slide rails to move laterally, thereby adjusting the position of the entire rotary sealing mechanism.
[0007] Furthermore, the rotary sealing mechanism includes a rotary platform with rotating guide wheels rotatably connected to its upper and lower sides. A circular track is rotatably connected between two of the rotating guide wheels. Several mounting plates are provided on the side of the circular track away from the rotating guide wheels, and each mounting plate is equipped with an oxyhydrogen flame gun body. The operator can slowly rotate the circular track (e.g., rotate 90°) to drive all the oxyhydrogen flame gun bodies to rotate synchronously around the glass tube, completing uniform sealing. The four oxyhydrogen flame gun bodies rotate around the glass tube to be sealed in an equidistant trajectory, achieving uniform heating of the entire circumference of the outer wall of the glass tube. After heating is completed, the end of the glass tube to be sealed melts and closes, and the sealing is completed.
[0008] Furthermore, the annular track has track grooves on both its inner and outer sides, and the two rotating guide wheels are rotatably connected in the track grooves. The track grooves are installed at the contact points between the rotating guide wheels and the annular track, forming a guiding system that limits the trajectory and supports sliding.
[0009] Furthermore, a rotating handle is detachably connected to the upper part of the annular track. The rotating handle is installed on the upper part of the annular track, and the operator can slowly rotate the annular track by rotating the handle (for example, rotate 90°), which will drive all the hydrogen-oxygen flame guns to rotate synchronously around the glass to be melted and sealed, so as to complete the uniform melting and sealing.
[0010] Furthermore, the limiting mechanism includes a support frame, on which a limiting seat is detachably connected. The limiting seat is provided with a limiting groove, the size of which is customized according to the diameter of the glass tube to ensure a tight fit between the glass to be melted and the limiting groove, preventing shaking or axial displacement during the melting process. This ensures the accuracy of the heating position and the stability of the melting process, while also providing good adaptability and ease of replacement, suitable for the positioning needs of glass tubes of different specifications.
[0011] Furthermore, each of the limiting grooves is provided with a rubber layer. The rubber layer in the limiting groove utilizes the good elasticity and cushioning properties of the rubber material to effectively fit the outer wall of the receiving and sealing glass tube, forming a flexible wrapping.
[0012] Furthermore, the bearing mechanism includes an electric push rod, which is mounted on the frame. The telescopic end of the electric push rod is fixedly connected to a support bracket, which provides adjustable support force and height positioning for the glass to be melted and sealed, ensuring that it remains horizontal and axially stable during the melting and sealing process, and avoiding uneven melting or damage caused by sagging, tilting or vibration.
[0013] Furthermore, a hydrogen-oxygen gas supply valve is provided on one side of the upper part of the frame. The hydrogen-oxygen gas supply valve is mainly used to regulate and control the supply flow and on / off status of hydrogen and oxygen.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] One end of the glass tube to be sealed is clamped onto the limiting mechanism, and the other end rests on the bearing mechanism. It passes through the rotating sealing mechanism located in the middle. The transverse mechanism is operated to move the rotating sealing mechanism to the specific position of the glass tube to be sealed. The flame position can be precisely aligned with the processing area. The rotating sealing mechanism is started, causing it to drive the flame to rotate around the glass tube. Due to the high temperature, small and stable flame of the hydrogen-oxygen flame, it can heat the glass tube evenly in the rotating state, thereby achieving 360° sealing without dead angles. When heated to the appropriate temperature, the glass partially melts and closes, completing the sealing process. This improves the accuracy and uniformity of the sealing heating, avoids the occurrence of deformation, bubbles or cracks on the glass tube sealing surface, and makes the operation simpler and the process more controllable.

This is to avoid unnecessarily lengthy descriptions and to facilitate understanding by those skilled in the art. Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this application and are not intended to limit the subject matter of the claims.
[0024] Please see Figure 1-3 As shown in the embodiment of this utility model, a glass tube sealing device for hydrogen-oxygen flame includes a frame 1, a transverse mechanism 2 is provided on the frame 1, and a rotary sealing mechanism 3 is provided on the transverse mechanism 2. The transverse mechanism 2 can move in the horizontal direction to adjust the relative position of the rotary sealing mechanism 3 and the glass tube to be sealed, so as to ensure that the flame is aligned with the area of the glass tube to be sealed. A limiting mechanism 4 is provided on one side of the upper part of the frame 1, and a bearing mechanism 5 is provided on the side of the frame 1 away from the limiting mechanism 4. The limiting mechanism 4 fixes one end of the glass tube to be sealed, and plays a positioning and limiting role to prevent the glass tube to be sealed from axially moving or shaking during the sealing process. The bearing mechanism 5 supports the other end of the glass tube to be sealed to prevent sagging deformation due to the large length of the glass tube to be sealed.
[0025] One end of the glass tube to be sealed is clamped onto the limiting mechanism 4, and the other end rests on the bearing mechanism 5. It passes through the rotating sealing mechanism 3 located in the middle. The transverse mechanism 2 is operated to move the rotating sealing mechanism 3 to the specific position of the glass tube to be sealed. The flame position can be accurately aligned with the processing part, improving the sealing quality. The rotating sealing mechanism 3 is started and rotated around the glass tube. Due to the high temperature, small and stable flame of the hydrogen-oxygen flame, it can heat the glass tube evenly in the rotating state, thereby achieving 360° sealing without dead angles. When heated to the appropriate temperature, the glass partially melts and closes, completing the sealing process. The rotation method makes the heating surface uniform, the sealing area has a dense structure, and the seal is complete. By using the rotating flame to uniformly and locally heat the glass tube at high temperatures, the accuracy and uniformity of the sealing heating are improved, and the operation is also simpler and the process is more controllable.
[0026] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The transverse mechanism 2 includes two electric slide rails 21, each with an electric slider 22 above it. A rotary sealing mechanism 3 is mounted on each of the two electric sliders 22. The electric sliders 22 drive the electric slide rails 21 to move laterally, thereby adjusting the position of the entire rotary sealing mechanism 3.
[0027] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The rotary sealing mechanism 3 includes a rotary platform 31. Rotary guide wheels 32 are rotatably connected to the upper and lower sides of the rotary platform 31. An annular track 33 is rotatably connected between the two rotating guide wheels 32. The rotating guide wheels 32 are rotatably connected to the rotary platform 31 through bearings and other mechanisms to support and drive the rotation of the annular track 33. A stable rotary support system is formed between the two rotating guide wheels 32 to prevent the annular track 33 from shaking or shifting. Several mounting plates 34 are provided on the side of the annular track 33 away from the rotating guide wheels 32. Each component is equipped with an oxyhydrogen flame gun body 35. In this example, there are four mounting plates 34, which means that the four oxyhydrogen flame gun bodies 35 are distributed on the track at 90° intervals. The operator can slowly rotate the annular track 33 (for example, rotate it 90°) to drive all four oxyhydrogen flame gun bodies 35 to rotate synchronously around the glass tube to be melted and sealed, thus completing the uniform melting and sealing. The four oxyhydrogen flame gun bodies 35 rotate around the glass tube to be melted and sealed in an equidistant trajectory to achieve uniform heating of the entire circumference of the outer wall of the glass tube. After heating is completed, the end of the glass tube melts and closes, and the melting and sealing is completed.
[0028] It should be noted that the oxyhydrogen flame gun body 35 is connected to the main gas supply pipe via a hose. In addition, a special rotary joint is provided between the flame nozzle and the main gas supply pipe. This structure allows the oxyhydrogen flame gun body 35 to rotate with the annular track 33 without twisting the hose. The rotary joint is a Deya DQ series miniature gas rotary joint, model DQ-01A, DQ-02A, etc.
[0029] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The inner and outer sides of the ring track 33 are provided with track grooves 331. Two rotating guide wheels 32 are rotatably connected in the track grooves 331. The track grooves 331 are installed at the contact points between the rotating guide wheels 32 and the ring track 33, forming a guide system that limits the trajectory and supports sliding.
[0030] Further, please refer to Figure 1 , Figure 2 and Figure 3A rotating handle 6 is detachably connected to the upper part of the annular track 33. The rotating handle 6 is installed on the upper part of the annular track 33 and is a manually driven operating mechanism. The operator can slowly rotate the annular track 33 (for example, rotate 90°) to drive all the hydrogen-oxygen flame gun bodies 35 to rotate synchronously around the glass tube to be melted, so as to complete the uniform melting and sealing. The rotating melting and sealing mechanism 3 supports the annular track 33 through two upper and lower rotating guide wheels 32. The operator drives the annular track 33 to rotate slowly by rotating the handle 6, so that multiple hydrogen-oxygen flame gun bodies 35 rotate synchronously around the glass tube to be melted and heat it, so as to achieve uniform melting and sealing of its outer wall.
[0031] Please see Figure 1 , Figure 2 and Figure 3 The limiting mechanism 4 includes a support frame 41, on which a limiting seat 42 is detachably connected. The limiting seat 42 is provided with a limiting groove 43, which is used to clamp and fix one end of the glass tube to be melted. The size of the limiting groove 43 is customized according to the diameter of the glass tube to ensure that the glass tube to be melted fits tightly with the limiting groove 43, avoiding shaking or axial displacement during the melting process, thereby ensuring the accuracy of the heating position and the stability of the melting process. It also has good adaptability and easy replacement, and is suitable for the positioning needs of glass tubes of different specifications.
[0032] Further, please refer to Figure 1 and Figure 2 As shown, a rubber layer 431 is provided inside the limiting groove 43. Utilizing the good elasticity and buffering properties of the rubber material, it can effectively fit the outer wall of the glass tube to be sealed when clamping it, forming a flexible wrapping. This not only enhances the clamping force of the limiting groove 43 on the glass tube to be sealed, preventing it from shaking or shifting during the sealing process, but also alleviates the mechanical stress and micro-crack risk that the rigid limiting structure may generate on the glass material, avoiding breakage or damage due to excessive local stress.
[0033] Further, please refer to Figure 1 and Figure 2 As shown, the bearing mechanism 5 includes an electric push rod 51, which is mounted on the frame 1. The telescopic end of the electric push rod 51 is fixedly connected to a support bracket 52. The electric push rod 51 in the bearing mechanism 5 is mounted on the frame 1 and serves as a drive unit. It achieves telescopic movement through electric control. The telescopic end is fixedly connected to the support bracket 52, which supports the free end of the glass tube to be melted and sealed. The support bracket 52 provides adjustable support force and height positioning for the glass tube to be melted and sealed, ensuring that it maintains a horizontal state and axial stability during the melting and sealing process, and avoiding uneven melting or damage caused by sagging, tilting or vibration.
[0034] Further, please refer to Figure 1 and Figure 2As shown, a hydrogen-oxygen gas supply valve 7 is provided on one side of the upper part of the frame 1. The hydrogen-oxygen gas supply valve 7 is mainly used to regulate and control the supply flow and on / off status of hydrogen and oxygen.
