[0001] This utility model relates to the field of airflow textile technology, specifically a connecting component and pipe used in an airflow spinning bag-grabbing machine. Background Technology

[0002] An air-jet spinning machine (also known as an air-jet spinning machine or air-jet yarn forming machine) is a type of mechanical equipment used for spinning yarn. Its working principle mainly relies on airflow to gather fibers and form yarn. Unlike traditional ring spinning machines, air-jet spinning machines use high-speed rotating airflow to gather fibers into yarn without the need for spindles.

[0003] In existing air-jet spinning machines, the cotton conveying pipe is fixed during use, and different models of carding machines cannot be opened synchronously, which affects the spinning table opening. Based on this, this application provides a connecting component and pipe for use in air-jet spinning bag grabbing machines. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a connecting component and pipe for use in air-jet spinning bagging machines, which solves the problem of inconvenient expansion of cotton conveying pipes in existing air-jet spinning equipment.

[0005] This utility model provides a connecting component for use in an air-jet spinning bag-grabbing machine, which includes a connecting pipe, a connecting cover below the connecting pipe, and an elastic sheet integrally formed below the connecting cover. There are several elastic sheets arranged in a circular array around the central axis of the connecting cover, and a sealing membrane is provided between every two elastic sheets for sealing between the two elastic sheets.

[0006] As a further improvement of this utility model, an installation cavity is provided on the side of the two elastic sheets that are close to each other, and the inner side of the installation cavity is adapted to the sealing membrane.

[0007] As a further improvement of this utility model, one end of the plurality of elastic sheets is set at a preset inclined angle and is close to each other to form an end closed area. The end closed area, together with the elastic sheet and the sealing film, forms a closed cavity.

[0008] As a further improvement of this utility model, the inner side of the connecting cover is provided with an internal thread, and the outer side near the bottom is provided with a connecting screw groove, and the internal thread is inserted into the connecting pipe.

[0009] As a further improvement of this utility model, the outer side of the connecting pipe is provided with an external thread, which is threadedly connected to the internal thread of the connecting cover.

[0010] As a further improvement of this utility model, the inner side of the connecting pipe is provided with a communication area for material to pass through.

[0011] This utility model also provides a pipe, which includes a pipe body and the above-mentioned connecting components. One or more connection ports are provided on the surface of the pipe body, and threads are provided at the connection ports. The threads are adapted to the threaded grooves on the outside of the connecting cover. The connecting components are installed on the pipe body by the cooperation of the threads and the threaded grooves on the outside of the connecting cover.

[0012] As a further improvement of this utility model, a passage area is provided in the middle of the inner side of the pipe body to form a material channel, and a sealing area in an annular arrangement is provided on the outer sides of both ends of the pipe body for connecting two pipes.

[0013] As a further improvement of this utility model, a docking hole is provided in the middle of the sealing area, and a connecting rod is installed at the docking hole for sealing the pipe connection.

[0014] As a further improvement of this utility model, a mating ring is provided between the two pipes to seal the pipe connection area.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model, through the threaded connection between the connecting pipe and the connecting cover, enables quick and convenient connection and disassembly operations, reducing installation and maintenance time and labor intensity.

[0017] The tight meshing of the connecting cover and the connecting pipe with the internal and external threads can prevent leakage of airflow and materials during the conveying process. The annular sealing area set at both ends of the pipe body and the connecting rod installed in the docking hole enhance the sealing performance when the pipe is connected.

[0018] The external thread on the outside of the connector and the internal thread on the inside of the connecting cover, as well as the connecting rod and the mating ring, ensure the stability of the pipe connection, prevent loosening and falling off, and improve the overall safety of the pipe connection. The inner wall of the connector and the middle passage area of ​​the pipe body are smoothed to reduce the frictional resistance when the material flows, ensure that the material (such as fiber) can pass through smoothly, and improve the conveying efficiency and stability.

[0019] The elastic sheet and sealing membrane design under the connecting cover can automatically adjust to form a channel according to the insertion of the connecting pipe, ensuring the tightness and stability of the connection, reducing the possibility of leakage, and the connection ports opened on the pipe surface can be connected or closed as needed to meet production needs, while allowing the pipeline to be quickly expanded and combined according to production requirements.

[0034] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the illustrations in a simple schematic manner.

[0035] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0036] Please see Figures 1-6 The connecting assembly 1 for use in an air-jet spinning bag-grabbing machine provided in this application includes a connecting pipe 11, a connecting cover 13 is provided below the connecting pipe 11, and an elastic sheet 14 is integrally formed below the connecting cover 13. There are several elastic sheets 14, which are arranged in a circular array around the central axis of the connecting cover 13. A sealing film 19 is provided between every two elastic sheets 14 for sealing the two elastic sheets 14.

[0037] The interior of the connecting tube 11 is smooth to ensure the smooth flow of fiber material, while the bottom of the connecting cover 13 is inverted conical to facilitate a tight connection with the connecting tube 11. The connecting cover 13 is provided with a guide groove to facilitate the flow of fiber to the connecting tube 11.

[0038] The elastic sheet 14 is connected to the bottom of the connecting cover 13 and has a certain elasticity. After the connecting pipe 11 is inserted, the elastic sheet 14 can be stretched open to cooperate with the set sealing membrane 19, so that the bottom of the elastic sheet 14 can be unfolded to form a channel, and the yarn can be captured by the airflow textile equipment.

[0039] The elastic sheet 14 and the sealing membrane 19 are made of highly elastic materials, which can ensure the stability and durability of the connection and reduce equipment failure and safety hazards caused by loose or broken connections.

[0040] Multiple elastic sheets 14 are arranged at one end at a preset tilt angle and are close to each other to form an end-closed region 110. The end-closed region 110, together with the elastic sheets 14 and the sealing membrane 19, forms a closed cavity.

[0041] An installation cavity 16 is formed on the inner side of two adjacent elastic sheets 14. The inner side of the installation cavity 16 is adapted to the sealing membrane 19, so that the sealing membrane 19 can be combined with the elastic sheet 14 to form a sealing structure. When the connecting pipe 11 is inserted, the elastic sheet 14 and the sealing membrane 19 can be unfolded to form a channel.

[0042] By setting the mounting cavity 16 and the closed cavity between the elastic sheets 14, the assembly can be quickly connected, and when closure is required later, the connecting pipe 11 can be removed to allow the elastic sheets 14 to close with the sealing membrane 19 to form a closed area, reducing the possibility of leakage and improving the sealing effect.

[0043] It should be noted that the design of the mounting cavity 16 allows the sealing membrane 19 to better fit the elastic sheet 14. The setting of the end sealing area 110 ensures the stability of the fiber during the conveying process and avoids material turbulence under the influence of airflow.

[0044] In some embodiments, the inner side of the connecting cover 13 is provided with an internal thread 17, and the outer side near the bottom is provided with a connecting screw groove 15, and the internal thread 17 is inserted into the connecting pipe 11.

[0045] Correspondingly, an external thread 12 is provided on the outside of the connecting pipe 11, and the external thread 12 is threadedly connected to the internal thread 17 of the connecting cover 13.

[0046] The inner side of the connecting cover 13 is provided with an internal thread 17 to ensure sufficient engagement length with the external thread 12 of the connecting pipe 11, thereby ensuring the firmness and stability of the connection.

[0047] The outer side of the connector 11 is provided with an external thread 12, the specification of which matches the internal thread 17 of the connecting cover 13, to ensure that it can be tightly engaged with the internal thread 17 of the connecting cover 13, preventing loosening and leakage.

[0048] Align the external thread 12 of the connector 11 with the internal thread 17 of the connecting cover 13, and connect the two threads together by rotation to ensure a tight and secure connection.

[0049] The inner side of the connecting pipe 11 has a connecting area 18 to ensure that materials (such as fibers) can pass through smoothly. The inner wall of the connecting area 18 is smooth, reducing resistance to material flow and improving the efficiency and stability of material conveying.

[0050] Understandably, the threaded connection of the internal thread 17 and the external thread 12 ensures a secure connection between the connecting cover 13 and the connecting pipe 11, preventing loosening or detachment during production and improving the stability and safety of the equipment. Furthermore, the tightness of the threaded connection effectively reduces leakage of airflow and materials during transport, minimizing material waste and environmental pollution.

[0051] Please see Figures 7-10 This application also provides a pipe 2 including the connection components described above. The pipe 2 includes a pipe body 21, and one or more connection ports 22 are provided on the surface of the pipe body 21. The connection ports 22 are provided with threads, and the threads are adapted to the threaded grooves on the outside of the connection cover 13.

[0052] The surface of the tube body 21 is provided with multiple connection ports 22, which are adapted to the connection screw grooves 15 on the outside of the connection cover 13. The connection ports 22 are evenly spaced on the surface of the tube body 21 and correspond one-to-one with the connection cover 13 and the connecting tube 11. The connection cover 13 can be connected as needed. When it is not needed, it can form a closed area to meet the needs of production.

[0053] The threads of the connector 22 are fully compatible with the connecting screw groove 15 on the outside of the connector cover 13, ensuring a tight fit during installation and preventing loosening and leakage.

[0054] By opening a connection port 22 on the surface of the tube body 21 and setting a matching thread, a firm connection between the connection cover 13 and the tube body 21 can be ensured, reducing problems caused by loose connection.

[0055] The connection port 22 makes the installation, disassembly and replacement of the connection cover 13 simple and quick. The connection operation can be completed quickly with tools (such as wrenches), which improves installation efficiency and facilitates regular maintenance of the equipment and replacement of parts, reducing maintenance costs and downtime.

[0056] The inner middle of the pipe body 21 is provided with a passage area 23 to form a material channel. Both ends of the pipe body 21 are provided with annular sealing areas 24 for the connection of two pipes 2. The middle of the sealing area 24 is provided with a docking hole 25, and a connecting rod is installed at the docking hole 25 for sealing the connection of the pipes 2. A docking ring 26 is provided between the two pipes 2 for sealing the connection area of ​​the pipes 2.

[0057] By setting annular sealing areas 24 at both ends of the pipe body 21 and installing connecting rods at the docking holes 25, the sealing performance of the two pipes 2 when docked can be ensured, effectively reducing material leakage during the transportation process and improving production efficiency and environmental cleanliness.

[0058] It should be noted that the connecting rod allows the two pipes 2 to form a firm connection when they are joined, preventing loosening and detachment, improving the stability and safety of the pipe 2 connection, and reducing failures and interruptions caused by weak connections. For example, this connection method, when used with the connecting components applied to the air-jet spinning bag grabber, can enable the rapid combination of pipes 2, which can be quickly expanded according to production needs and can be added as needed without affecting normal production.

[0059] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
