Description

Technical Field

[0001] The utility model relates to the technical field of capillary welding, in particular to a capillary network using an induction welding method. Background Art

[0002] Most of the existing capillary welding technologies use plastic welding technology based on hot melt technology or infrared heating technology. The existing technology has the following technical problems:

[0003] 1. High energy consumption: Since capillary welding requires heating the capillary end and the main pipe opening with different heating heads, and then disconnecting the heating heads to merge the two parts so that the molten parts are fused together, in order to ensure that the molten state is maintained when merging after heating, the heating process needs to have a high overheating. At the same time, in order to ensure the temperature of the head, the other parts of the entire equipment will also have a high temperature, resulting in excessive energy consumption; at the same time, in order to ensure the molten state of the mold, the other parts of the equipment cannot be strongly cooled, so the equipment continues to heat up during the processing and production process. As a result, the thermal expansion coefficients of various components are different, which affects the processing accuracy of the equipment, making it impossible for the equipment to produce continuously, and it has to be stopped intermittently for cooling;

[0004] 2. Unstable welding quality: Since the two parts of the molten plastic need to be separated from the heating end and then butted against each other, the surface will cool down first during this process, affecting the mutual melting when merging; at the same time, since the positions between the two parts of the molten plastic when merging are completely dependent on the random shaping of the molten plastics at both ends when butt-jointing, it is difficult for the mutual fusion of the materials to reach an ideal state; when the final required shape is not achieved, an external shaping mold needs to be used, and the cooling of the molten plastic by the mold will affect the mutual fusion, resulting in a cold weld in the fused part, which may cause slow leakage during use;

[0005] 3. Welding point blockage: During the butt-jointing process of the two molten ends, a certain pressure needs to be applied to the breakpoints to make them fuse with each other and form a preset shape. At this time, the molten material will penetrate into all gaps, and the function of the capillary network itself is guaranteed by the channel from the main pipe to the capillary. The processing process at the welding point will cause the channel to narrow or even partially block, thus affecting the performance of the capillary network;

[0006] 4. Complex equipment: Since capillary welding requires the execution of a completely consistent welding process on dozens of solder joints at the same time, that is, each solder joint must repeat the process of melting separately - separating the heating end - closing the mold, that is, merging the solder joints - demolding. The heating component and the moving component are integrated and need to perform precise movements, which makes the equipment complex and has a high failure rate.

[0007] Therefore, there is an urgent need for a capillary network using an induction welding method to solve the above problems. Utility Model Content

The setting of the ring can limit the insertion depth. The metal wire tube 04 is sleeved on the top outer wall of the capillary network branch tube 02, and the top of the metal wire tube 04 is in contact with the capillary network main tube 01 to form a structure in which the ribbed metal hollow tube 03 and the metal wire tube 04 sandwich the capillary network main tube 01 and the capillary network branch tube 02. During induced welding, a magnetic generator is used to induce the ribbed metal hollow tube 03 to generate heat, thereby melting the plastic at the welding position of the capillary network main tube 01 and the capillary network branch tube 02, and the capillary network branch tube 02 is pushed toward the welding position, so that the molten part of the material merges with each other, and part of the material bulges toward the periphery, forming a trumpet shape with a larger root in contact with the capillary network main tube 01 and gradually tapering toward the extension direction of the capillary network branch tube 02. The welding process is completed after the welding position is cooled.

The structure of the capillary network main pipe 01 and the capillary network branch pipe 02 is induced to heat up by a magnetic generator during induction welding, thereby melting the plastic at the welding position of the capillary network main pipe 01 and the capillary network branch pipe 02, and pushing the capillary network branch pipe 02 toward the welding position, so that the molten part of the material fuses with each other, and part of the material bulges toward the periphery, forming a trumpet shape with a larger root in contact with the capillary network main pipe 01 and gradually tapering toward the extension direction of the capillary network branch pipe 02.
