[0022] 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 with reference to the accompanying drawings and specific implementation methods.

[0023] In the present invention, an improved trachea 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.

[0024] like Figures 1 to 8As shown, the air pipe connection node forming structure includes a connector 3, which is composed of at least two interconnected tube bodies 13 (such as Figure 1 The four-way shown, such as Figure 2 Each 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.

[0025] In order to further enhance the strength of the connection, a reinforcement sheet 2 is welded to the first welding area 12. The reinforcement sheet 2 provides additional structural support and effectively prevents failure of the welding portion due to external forces.

[0026] Inside the connector 3 lies a sealed inner liner 4. This sealed inner liner 4 is also dual-pass or multi-pass, consisting of a number of sealed tubes 42, the same number as the tube body 13, and each sealed tube 42 is interconnected. The free end edges of the sealing tubes 42 are welded to the inner wall of the corresponding tube body 13, ensuring a complete seal between each channel. This design prevents gas leakage when passing through the connector 3, enhancing the sealing, safety, and reliability of the entire system.

[0027] Further, if Figure 5 As shown in the second figure, the same reinforcing sheet 2 is connected to the opposite first welding area 12, firmly combining the two. This design improves the rigidity and durability of the overall structure.

[0028] The tube body 13 is manufactured by rolling segments 1. Second weld zones 14 are provided on both long sides of the segments 1 to seal the segments 1 and ensure a well-sealed tube body. A connection port 11 is punched at one end (the butt end) of the segments 1. The first weld zone 12 is formed by welding adjacent segments 13 together around the connection ports 11. This welding method simplifies the production process and ensures a tight seal at the joint.

[0029] In terms of material selection, the pipe segments 1 and the reinforcement sheets 2 are usually made of a mesh coating material, and the innermost and outermost layers are both 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 strength 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.

[0030] In summary, the design of the tracheal connection node molding structure is simple and easy to process and manufacture. This structural design not only reduces processing costs but also improves product processing quality, ensuring high practicality and reliability in practical applications.

[0031] The production process of this utility model is as follows:

[0032] Step S1: First, select a tube segment 1 made of a suitable material and perform a punching process on it (such as Figure 3 As shown), a connection port 11 of predetermined size and shape is formed (the connection port 11 is preferably as shown in FIG. 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.

[0033] Step S2: Fold the tube segment 1 in half along its length to form a symmetrical half-folded shape. This folding operation provides a basis for welding alignment in subsequent steps.

[0034] 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 during the subsequent welding process. This step can be done with the help of a fixture or positioning jig to ensure accurate alignment.

[0035] Step S4: using heat welding or ultrasonic welding technology, the adjacent tube segments 1 are welded together in sequence along the periphery of each connection port 11 to form a first welding area 12 .

[0036] 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.

[0037] Step S5: unfold each tube segment 1 in sequence, then take a number of reinforcement sheets 2, weld the reinforcement 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 enhance the structural strength and durability of the node.

[0038] 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 the drawing, the pipe body 13 is formed, and the welding position thereof is the second welding area 14. Through this step, the overall structure forms a two-way or multi-way connector 3, realizing the connection function of multiple gas pipes.

[0039] Step S7: Take the sealed inner container 4 (such as Figure 5As shown in the fourth figure of FIG), the sealed inner container 4 includes the same number of sealing tubes 42 as the tube body 13, and is two-way (as shown in FIG. Figure 8 as shown) or multi-pass shape (as Figure 5 (as shown) to adapt to the structure of connector 3. The sealing liner 4 is inserted into 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 connector 3 to form a third welding area 41. The sealing liner 4 is typically made of soft PVC, TPU, or other stretchable soft film material, making it easy to install and can be directly inserted into connector 3. The main function of the sealing liner 4 is to add a sealing pipe membrane to the innermost layer of connector 3, forming a complete sealing system within connector 3 and significantly improving the sealing performance of connector 3.

[0040] The order of step S1 and step S2 can be interchanged according to actual production needs to improve production flexibility and efficiency.

[0041] Furthermore, the forming step of 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 objects are replaced by sealing sheets, and finally a sealed inner liner 4 that is compatible with the connector 3 can be formed.

[0042] like Figure 1 、 Figure 3-Figure 5 The figure shows the first embodiment of the present invention. In this embodiment, the connector 3 finally processed is a cross.

[0043] 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 tube sheets 1 can be two separate tube sheets 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 (as shown), achieving an integrated connection. At this point, step S1 punches a hole in the middle of the long tube segment 5 to ensure that the connecting portion between the two tube segments 1 is not severed, thus maintaining the integrity and stability of the overall structure. This design further simplifies the production process and improves production efficiency.

[0044] This method for forming a gas pipe connection node has many advantages, which make it more efficient and reliable in practical applications. Specifically, these advantages include:

[0045] 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.

[0046] 2. High efficiency: This method adopts the method of folding and stacking multiple layers to significantly improve the efficiency of punching and welding.

[0047] 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. The addition of reinforcement plates significantly increases the structural strength.

[0048] 4. Excellent sealing performance: A sealing liner is added to the connector, which significantly improves the sealing performance of the connector.

[0049] 5. Modular design: This approach allows for flexible design of multi-way or single-way 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.

[0050] 6. Adaptability and scalability: The process is applicable to segments of different materials and specifications and can be adjusted and improved according to specific needs.

[0051] In summary, this 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.
