Description

Technical Field

[0001] This utility model relates to the field of electric heating tube processing technology, and in particular to a high-temperature sealing device for processing electric heating tubes. Background Technology

[0002] Electric heating elements are widely used in industrial, household appliances, and laboratory equipment. The sealing process is a crucial step in ensuring the internal heating element is isolated from the external environment, preventing the ingress of moisture and impurities. Traditional sealing methods include welding, adhesive sealing, and mechanical sealing, but these methods may suffer from insufficient sealing or complex operation at high temperatures. Glass powder sealing technology, due to its high temperature resistance and excellent sealing performance, has been widely used in the field of electric heating element sealing.

[0003] Traditional preheating and sealing equipment suffers from significant shortcomings in temperature control, ease of operation, adaptability, and production efficiency. First, these devices struggle to achieve precise temperature control, which not only affects the stability of sealing quality but can also lead to increased product defects or scrap rates. Second, since most equipment relies on manual operation or only has semi-automatic functions, it requires substantial human intervention, resulting in low efficiency, susceptibility to human error, and increased training and management costs. Furthermore, existing equipment is typically designed to handle only specific sizes and types of heating elements, lacking flexibility and the ability to quickly adapt to different product specifications, thus limiting the company's production capacity and market responsiveness. Finally, the separation of preheating and sealing processes further extends the production cycle and reduces overall production efficiency. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0024] A high-temperature sealing device for processing electric heating tubes, such as Figures 1-8As shown, the device includes a mounting base 1, an electric guide rail 2, second sliders 11, a preheating box 3, a preheater 19, a high-frequency sealing machine 4, a first cylinder 5, a second cylinder 6, a first guide plate 7, a mounting cylinder 9, a heating tube 10, and an adjustment mechanism. The electric guide rail 2 is fixedly connected to the top of the mounting base 1. The electric guide rail 2 is U-shaped, and twenty second sliders 11 are slidably connected to the electric guide rail 2 along its circumference. The preheating box 3 is fixedly connected to the top of the electric guide rail 2, with the front of the electric guide rail 2 extending beyond the front of the preheating box 3. A material inlet 3 is located on the left side of the preheating box 3. 1. A preheater 19 and a high-frequency sealing machine 4 are fixedly connected to the top of the preheating box 3. The preheater 19 is connected to the preheating box 3. A first cylinder 5 is fixedly connected to the front side of the high-frequency sealing machine 4. A second cylinder 6 is fixedly connected to the piston rod of the first cylinder 5. A first guide plate 7 is fixedly connected to the piston rod of the second cylinder 6. An adjustment mechanism is connected inside the first guide plate 7. Two mounting cylinders 9 are connected to the adjustment mechanism. A heating tube 10 is fixedly connected to the side of the mounting cylinder 9 away from the adjustment mechanism. The high-frequency sealing machine 4 is electrically connected to the heating tube 10.

[0025] like Figures 1-4 As shown, the adjustment mechanism includes a first bidirectional screw 8 and a first slider 81. The first bidirectional screw 8 is rotatably connected inside the first guide plate 7. One end of the first bidirectional screw 8 passes through the first guide plate 7. Two first sliders 81 are threadedly connected to the first bidirectional screw 8. The first sliders 81 are slidably connected to the first guide plate 7 and are fixedly connected to the mounting cylinder 9.

[0026] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, it also includes a second bidirectional screw 12, a third slider 13, a mounting ring 14, a clamping block 15, an elastic element 16, and a rubber block 151. The second bidirectional screw 12 is rotatably connected inside the second slider 11. One end of the second bidirectional screw 12 passes through the second slider 11. Two third sliders 13 are threadedly connected to the second bidirectional screw 12. The third sliders 13 are slidably connected to the second slider 11. The mounting ring 14 is fixedly connected to the third slider 13. Two clamping blocks 15 are slidably connected inside the mounting ring 14. An elastic element 16 is fixedly connected between the two clamping blocks 15 and the third slider 13. The elastic element 16 is set as a helical spring. A rubber block 151 is fixedly connected to the side of the two sliders that are close to each other.

[0027] When sealing the heating element is required, a mixture of glass powder and glue is poured into the end of the heating element. The second slider 11 is slid to the feeding port 31 via an electric slide rail. One end of the heating element is inserted between the two clamping blocks 15 of one mounting ring 14, and the other end is inserted between the two clamping blocks 15 of the other mounting ring 14. Under the elastic force of the elastic element 16, the clamping blocks 15 clamp and fix the end of the heating element. The rubber block 151 increases the friction between the end of the heating element and the clamping blocks 15, improving the stability of the heating element. The preheating machine 19 then... Heating occurs inside the preheating box 3, causing the second slider 11 to slide clockwise along the electric guide rail 2. This allows the end of the heating element to enter the preheating box 3 for preheating, combining preheating and sealing. The U-shaped electric guide rail 2 extends the preheating time of the heating element in the preheating box 3 and improves the sealing efficiency of this sealing device. Rotating the second bidirectional screw 12 controls the distance between the two third screws, allowing adjustment of the distance between the mounting rings 14 according to the type and size of the heating element, thus improving the applicability of this sealing device. The clamps 15 of the same second slider 11... This device can accommodate both ends of the same heating element, or place one end of each of two different heating elements between two clamps 15, further improving the applicability of the sealing equipment. When the second slider 11 slides close to the heating element 10, the first cylinder 5 drives the second cylinder 6 to move backward, and then the second cylinder 6 drives the heating element 10 to move upward, moving the heating element 10 away from the electric guide rail 2. When the end of the heating element is directly below the heating element 10, the first cylinder 5 drives the second cylinder 6 to move forward, so that the heating element 10 and the end of the heating element are aligned. On the same vertical plane, the second cylinder 6 drives the heating tube 10 to move downward, so that the end of the heating tube is inserted into the heating tube 10. The high-frequency sealing machine 4 heats the heating tube 10 by passing electricity, so that the end of the heating tube is heated quickly and the glass powder is melted. The melted glass powder seals the end of the heating tube, thereby achieving high-temperature sealing of the heating tube and achieving insulation. The sealed heating tube can then be removed manually. The first bidirectional screw 8 is rotated so that the first slider 81 slides along the first guide plate 7, thereby ensuring that the heating tube 10 can be aligned with the end of the heating tube.

[0028] like Figure 5As shown, it also includes insulation plates 17 and rubber strips 18. Two insulation plates 17 are fixedly connected inside the preheating box 3. The insulation plates 17 are arranged vertically and horizontally, and each insulation plate 17 has a through groove 171 for the heating pipe to pass through. The upper and lower through grooves 171 are aligned with each other. Rubber strips 18 are fixedly connected to the inner walls on both sides of the through grooves 171, and a gap is left between the two rubber strips 18 for the heating pipe to pass through. When the preheater 19 is running, the insulation plates 17 can isolate the temperature inside the preheating box 3, prevent the high temperature from spreading and lowering the temperature of the preheating box 3, and also prevent the working environment temperature from being too high. When the heating pipe is removed, it can prevent the high temperature inside the preheating box 3 from burning the workers, thus improving the safety of this sealing equipment. The through grooves 171 can ensure the normal movement of the heating pipe inside the preheating box 3, and the rubber strips 18 can improve the sealing performance of the insulation plates 17 without affecting the sliding of the heating pipe inside the through grooves 171.

Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
