[0025] Embodiment 1
[0026] Please refer to Figures 1 - 4 , the present utility model provides the following technical solutions:
[0027] A door seal welding device, comprising:
[0028] housing 1;
[0029] Welding mechanism, the welding mechanism includes a first pneumatic rod 2, a mounting plate 3, a limit block 4, a motor 5, a threaded rod 6, a slider 7, a welding torch head 8 and a limit rod 22. There are two first pneumatic rods 2 and two limit blocks 4. Both of the two first pneumatic rods 2 are fixedly connected to the upper end of the housing 1. The mounting plate 3 is fixedly connected to the upper end of the first pneumatic rod 2. Both of the two limit blocks 4 are fixedly connected to the lower end of the mounting plate 3.

[0030] Docking mechanism, the docking mechanism is fixedly connected to the upper end of the housing 1 to realize the docking of two refrigerator door seal materials.
[0031] In a specific embodiment of the present invention, the housing 1, as the main frame of the device, provides a stable support foundation. There are two first pneumatic rods 2, which serve as the driving foundation for the up and down movement of the welding mechanism. The mounting plate 3 provides an installation platform for other components. There are two limit blocks 4, which are used to define the movement range and support components such as the motor 5. The motor 5 provides a power source for the threaded rod 6. The threaded rod 6 provides a slide rail for the slider 7. The slider 7 and the welding torch head 8, the welding torch head 8 is fixedly connected to the lower end of the slider 7. There is a sliding nut in the slider 7. The slider 7 reciprocally slides on the circumferential surfaces of the threaded rod 6 and the limit rod 22 to precisely weld the refrigerator door seal material. The limit rod 22, when the threaded rod 6 rotates, the slider 7 will not rotate with the rotation of the threaded rod 6 due to the restriction of the limit rod 22.
[0032] Specifically, please refer to Figures 1 - 4 , the docking mechanism includes fixed blocks 9, second pneumatic rods 10, molds 11, sliding grooves 12, sliding blocks 13 and pressure rods 14. There are two fixed blocks 9, two second pneumatic rods 10, two molds 11, two sliding blocks 13 and two pressure rods 14. Both of the two fixed blocks 9 are fixedly connected to the upper end of the housing 1. The two second pneumatic rods 10 are respectively fixedly connected to the closer ends of the two fixed blocks 9. The two molds 11 are respectively fixedly connected to the closer ends of the two second pneumatic rods 10. The sliding groove 12 is opened on the upper end of the housing 1.

The two pressure rods 14 are both fixedly connected to the lower end of the mounting plate 3.
[0033] In this embodiment: There are two fixed blocks 9, which serve as the basic support units of the docking mechanism. There are two second pneumatic rods 10, which use pneumatic power to squeeze the docking part of the two molds 11, so that the two refrigerator door seal materials can be closely attached, preventing problems such as loose welding joints and low airtightness during the welding process. There are two molds 11, with grooves opened at the upper ends, which are used to accommodate and accurately align the refrigerator door seal materials to be welded. The sliding grooves 12 provide a smooth sliding path for the sliding blocks 13. There are two sliding blocks 13, which are driven by the second pneumatic rods 10 to drive the molds 11 to reciprocate in the sliding grooves 12. There are two pressure rods 14. When the first pneumatic rod 2 drives the mounting plate 3 to move downward, the pressure rods 14 will also move downward and press against the refrigerator door seal materials in the grooves of the two molds 11, preventing the refrigerator door seal materials from shifting due to the docking of the two molds 11.
[0034] For details, please refer to Figures 1 - 4 , a suction fan 15 is fixedly connected to the upper end of the housing 1, an exhaust gas box 17 is fixedly connected to one side end of the housing 1, and an exhaust pipe 16 is connected between the suction fan 15 and the exhaust gas box 17.
[0035] In this embodiment: The suction fan 15 is used to effectively suck and remove the smoke and harmful gases generated during the welding process, keeping the working environment clean and the workers healthy. The exhaust gas box 17 functions to collect the welding exhaust gas and residues extracted by the suction fan 15, avoiding direct discharge of pollutants into the environment, facilitating later centralized treatment or safe discharge, and meeting the high environmental protection standards required by modern industrial production. The exhaust pipe 16 ensures that the exhaust gas generated by welding can be smoothly transferred from the working area to the exhaust gas box 17.
[0036] For details, please refer to Figures 1 - 4 , a U-shaped base 18 is fixedly connected to the upper end of the housing 1, and a light-shielding plate 19 is connected inside the U-shaped base 18.
[0037] In this embodiment: The U-shaped base 18 has an open surface facing upward, providing a stable installation platform for the light-shielding plate 19. The light-shielding plate 19 is used to block the strong light and ultraviolet radiation that may be generated during the welding process, effectively protecting the operator's eyes.
[0038] For details, please refer to Figures 1 - 4 , a fixed rod 20 is fixedly connected to the lower end of the housing 1, and a chassis 21 is fixedly connected to the lower end of the fixed rod 20.
[0039] In this embodiment: There are multiple fixed rods 20, which serve as the bridges between the housing 1 and the ground, enhancing the vertical support force of the equipment through rigid connections. There are multiple chassis 21, which can evenly disperse the weight of the equipment, avoiding concentrated pressure on the ground.
[0040] For details, please refer to Figures 1 - 4 , and the material of the housing 1 is stainless steel.
[0041] In this embodiment: The stainless-steel material has the characteristics of corrosion resistance, high temperature resistance, easy maintenance, and high strength, and the surface is smooth, which is convenient for personnel to clean.
[0042] The working principle and usage process of the present utility model: Through this device, personnel put the refrigerator door seal material into the grooves opened by the two molds 11. The second air pressure rod 10 drives the mold 11 to slide in the sliding groove 12 through the sliding block 13 for docking, and the power of the second air pressure rod 10 squeezes the docking part of the two molds 11, so that the two refrigerator door seal materials can be closely fitted, preventing problems such as insecure welding joints and low airtightness during the welding process. At the same time, when the first air pressure rod 2 moves downward, the pressure rod 14 will also move downward to press against the refrigerator door seal material in the mold 11, so that the refrigerator door seal material will not be offset due to the docking of the two molds 11. Then, start the motor 5 to drive the threaded rod 6 to rotate. The slider 7 will not rotate with the rotation of the threaded rod 6 due to the limitation of the limiting rod 22. There is a sliding nut in the slider 7. The welding torch head 8 at the lower end is driven by the slider 7 to reciprocate on the circumferential surfaces of the threaded rod 6 and the limiting rod 22 to precisely weld the refrigerator door seal material. After one side is welded, personnel can flip the refrigerator door seal material and weld the other side in the above-mentioned device operation mode, solving the problems of low efficiency and insufficient precision existing in traditional manual door seal processing.
[0043] Finally, it should be noted that: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
