[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] In the present invention, an improved air pipe connection node molding structure is described, and its design and manufacturing process are aimed at improving the sealing performance and structural strength of the connection node.

[0036] like Figures 1 to 8 As shown, the air pipe connection node forming structure includes a connector 3, and the connector 3 is composed of at least two interconnected pipe bodies 13 (such as Figure 1 The four-way shown in Figure 2Each adjacent pipe body 13 is provided with a first welding area 12 for sealing connection at its butt joint to ensure a stable connection and good sealing performance between the two pipe bodies.

[0037] In order to further enhance the strength of the connection, a reinforcing sheet 2 is welded on the first welding area 12. The reinforcing sheet 2 provides additional structural support, effectively preventing the welding part from failing due to external force.

[0038] Inside the connector 3, a sealed inner liner 4 is provided. The sealed inner liner 4 is also in a double-pass or multi-pass shape, and is composed of a plurality of sealed tubes 42, the number of which is the same as the tube body 13, and each sealed tube 42 is interconnected. The free end edge of the sealed tube 42 is welded to the inner wall of the corresponding tube body 13 to ensure complete sealing between each channel. This design ensures that the gas will not leak when passing through the connector 3, thereby enhancing the sealing, safety and reliability of the entire system.

[0039] Furthermore, if Figure 5 As shown in the second figure, the same reinforcing sheet 2 is connected to the opposite first welding area 12, and the two are firmly combined together. This design improves the rigidity and durability of the overall structure.

[0040] In terms of manufacturing the pipe body 13, the pipe body 13 is rolled from the pipe segment 1. The two long sides of the pipe segment 1 are provided with a second welding area 14 for sealing the pipe segment 1 to ensure that the formed pipe body has good sealing performance. A connection port 11 is punched at one end (butt end) of the pipe segment 1, and the first welding area 12 is formed by welding the peripheries of the connection ports 11 of adjacent pipe bodies 13 together. This welding method simplifies the production process and ensures the sealing of the connection node.

[0041] In terms of material selection, the pipe segments 1 and the reinforcement sheets 2 are usually made of mesh coating materials, and the innermost and outermost layers are coatings, usually made of PVC (polyvinyl chloride), TPU (thermoplastic polyurethane) or other polymer materials. The coating can be conveniently welded by hot-melt connection. The middle layer is provided with a cloth layer or a mesh layer (such as a fiber mesh or a woven mesh) to improve the tensile resistance and enhance the durability and stability of the pipe body. The sealing liner 4 is usually made of soft PVC, TPU or other stretchable soft film materials. The selection of these materials ensures that the sealing liner 4 can maintain a good sealing state under various working conditions.

[0042] In summary, the design of the air pipe connection node forming structure is simple and easy to process and manufacture. This structural design not only reduces the processing cost, but also improves the processing quality of the product, ensuring high practicality and reliability in practical applications.

[0043] The present invention also provides a specific process method for manufacturing the above-mentioned air pipe connection node forming structure, aiming to achieve reliable quality air pipe connection node production through simple and efficient steps. The specific method steps are as follows:

[0044] Step S1: First, a tube segment 1 made of a suitable material is selected and punched (e.g. Figure 3 As shown), a connection port 11 of predetermined size and shape is formed (the connection port 11 is preferably as shown in Figure 3 This step can utilize equipment such as laser cutting or punching machine to ensure the accuracy and consistency of the connection port 11.

[0045] Step S2: Fold the tube segment 1 in half along the length direction of the tube segment 1 to make it present a symmetrical half-folded shape. This folding operation provides a basis for welding alignment in subsequent steps.

[0046] Step S3: stack all the folded tube sheets 1 in sequence (such as Figure 5 As shown in the first figure, each connection port 11 is strictly aligned to ensure the accurate position of the connection port 11 in the subsequent welding process. This step can be precisely aligned with the aid of a fixture or a positioning jig.

[0047] Step S4: using heat welding or ultrasonic welding technology, the adjacent pipe segments 1 are welded together in sequence along the periphery of each connection port 11 to form a first welding area 12 .

[0048] For example, if Figure 4 In one embodiment shown, the edges of ports B and C should be aligned and welded together, the edges of ports D and E should be aligned and welded together, the edges of ports F and G should be aligned and welded together, and the edges of ports H and A should be aligned and welded together.

[0049] Step S5: unfold each tube segment 1 in sequence, then take a number of reinforcing sheets 2, weld the reinforcing sheets 2 to the opposite first welding areas 12, and connect the two welding areas (such as Figure 5 The reinforcement sheet 2 is intended to increase the structural strength and durability of the node.

[0050] Step S6: Weld the two long side edges of each tube segment 1 together (such as Figure 5 As shown in the third figure of FIG), it is formed into a tube body 13, and its welding position is a second welding area 14. Through this step, the overall structure forms a two-way or multi-way connector 3 to achieve the connection function of multiple air pipes.

[0051] Step S7: Take the sealed inner container 4 (such as Figure 5 As shown in the fourth figure of FIG. 1 , the sealed inner liner 4 includes the same number of sealed tubes 42 as the tube body 13, and is in a two-way manner (such as Figure 8as shown) or multi-pass shapes (as Figure 5 As shown in the figure, to adapt to the structure of the connector 3. The sealing liner 4 is inserted into the connector 3, and the free end edges of each sealing tube 42 in the sealing liner 4 are welded to the inner wall of the corresponding tube body 13 in the connector 3 to form a third welding area 41. The sealing liner 4 is usually made of soft PVC, TPU or other stretchable soft film materials, which is easy to install and can be directly inserted into the connector 3. The main function of the sealing liner 4 is: it is equivalent to adding a sealing pipe membrane to the innermost layer of the connector 3, forming a complete sealing system in the connector 3, and significantly improving the sealing performance of the connector 3.

[0052] The order of step S1 and step S2 can be interchanged according to actual production needs to improve production flexibility and efficiency.

[0053] Furthermore, the step of forming the sealed inner liner 4 includes: taking a number of sealing sheets, and sequentially performing steps similar to steps S1, S2, S3, S4 and S6, except that the processing object is replaced by the sealing sheet, and finally a sealed inner liner 4 adapted to the connector 3 can be formed.

[0054] like Figure 1 , Figure 3-Figure 5 The embodiment 1 of the present invention is shown. In this embodiment, the final processed connector 3 is a cross.

[0055] In the second embodiment, Figure 2 , Figure 6-Figure 8 As shown, the connector 3 is a two-way design. In this design, the two pipe segments 1 can be two separate pipe segments 1 (such as Figure 6 As shown), a long tube sheet 5 can also be folded in half along its width direction (as shown Figure 7 At this time, step S1 punches holes in the middle of the long tube segment 5 to ensure that the connecting part between the two tube segments 1 is not cut off, thereby ensuring the integrity and stability of the overall structure. This design further simplifies the production process and improves production efficiency.

[0056] The air pipe connection node forming method has many advantages, which make it show high efficiency and reliability in practical applications. Specifically, these advantages include:

[0057] 1. The process is concise and clear: the entire molding method is divided into several steps, each of which is easy to implement, reducing the possibility of errors and improving production efficiency.

[0058] 2. High efficiency: This method adopts the method of folding and stacking multiple layers to significantly improve the efficiency of punching and welding.

[0059] 3. Strong welding: The design of multiple welding, including the first welding area, the second welding area and the third welding area, ensures the overall stability of the structure. Reinforcement sheets are also added to significantly increase the structural strength.

[0060] 4. Excellent sealing performance: A sealing liner is added to the connector, which significantly improves the sealing performance of the connector.

[0061] 5. Modular design: This method allows for flexible design of multi-pass or single-pass connectors, suitable for a variety of application scenarios. The modular design concept not only simplifies the production process, but also improves the versatility and market adaptability of the product.

[0062] 6. Adaptability and scalability: The process is suitable for segments of different materials and specifications and can be adjusted and improved according to specific needs.

[0063] In summary, the air pipe connection node forming method provides an ideal solution for the production of high-quality air pipe connection nodes through a streamlined process, a simple and efficient welding process, a strong structural bond and superior sealing performance, which can effectively improve production efficiency and product competitiveness.
