[0002] In the production of synthetic fibers, the drawing nozzle is one of the key components. For example, in the production of polyester fibers and nylon fibers, the drawing nozzle stretches the polymer melt or solution into fine filaments, which are then processed to produce fibers of various specifications and properties for use in textiles, clothing, industrial textiles and other fields.

[0003] For example, the authorized patent with announcement number CN207811946U (a spinneret stretching device for an ecological greenhouse film) includes a nozzle and a housing located below the nozzle; an adjusting plate is provided inside the housing, and an adjuster is connected to the adjusting plate; the adjuster passes through the outer wall of the housing and is connected to the adjusting plate, and a sealing device is also provided at the contact point between the adjuster and the outer wall of the housing, the sealing device being hollow; a cooling mechanism is provided around the nozzle, and the cooling mechanism has an S-shaped channel for the circulation of coolant.

[0004] While the existing technologies mentioned above are convenient for adjusting and controlling the forming diameter of the spinning yarn, they lack airflow guidance capabilities. Consequently, when the fabric drawing yarn is ejected, the lack of airflow assistance and stabilization results in the yarn being prone to shaking and uneven forming, affecting the continuity of the fabric drawing yarn and the quality of the finished product. Therefore, the market urgently needs to develop a fabric drawing yarn nozzle structure to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a fabric drawing yarn nozzle structure to solve the problem mentioned in the background art that when fabric drawing yarn is ejected, the lack of airflow to assist traction and stabilize it leads to easy shaking of the yarn, uneven forming, and affects the continuity of fabric drawing yarn and the quality of the finished product.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric drawing filament nozzle structure, comprising a nozzle body, an input cavity provided on one side of the nozzle body, a filament outlet hole provided along one side of the input cavity inside the nozzle body, the input cavity communicating with the filament outlet hole, an airflow annular cavity provided along the outer side of the input cavity inside the nozzle body, an airflow conveying cavity provided along one side of the airflow annular cavity inside the nozzle body, and a traction hole provided along one side of the airflow conveying cavity inside the nozzle body, the airflow annular cavity communicating with the traction hole through the airflow conveying cavity.

[0012] Preferably, an mounting ring plate is fixedly installed at one end of the outer side of the nozzle body. The mounting ring plate has multiple mounting through holes arranged in a ring at intervals.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By setting up an airflow annular cavity, an airflow conveying cavity and a traction hole, the airflow annular cavity and the traction hole are connected through the airflow conveying cavity to form an effective airflow guiding path.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a fabric drawing filament nozzle structure, comprising a nozzle body 1, an input cavity 101 provided on one side of the nozzle body 1, a filament outlet hole 102 provided along one side of the input cavity 101 inside the nozzle body 1, the input cavity 101 and the filament outlet hole 102 communicating, an airflow annular cavity 103 provided along the outer side of the input cavity 101 inside the nozzle body 1, an airflow conveying cavity 104 provided along one side of the airflow annular cavity 103 inside the nozzle body 1, and a traction hole 105 provided along one side of the airflow conveying cavity 104 inside the nozzle body 1, the airflow annular cavity 103 and the traction hole 105 communicating through the airflow conveying cavity 104.

[0024] This design allows for effective airflow guidance during the fabric stretching filament ejection process. The airflow annular cavity 103 connects with the traction hole 105 via the airflow conveying cavity 104, providing auxiliary traction and stabilization. This solves the problem of insufficient airflow for auxiliary traction and stabilization during fabric stretching filament ejection, which leads to filament vibration, uneven forming, and affects the continuity of fabric stretching filaments and the quality of the finished product. This design also increases practicality.

[0025] Please see Figure 2An extension plate 4 is fixedly installed inside the nozzle body 1 along one side of the wire outlet hole 102. The extension plate 4 has a wire spinneret hole 401 inside, which is connected to the wire outlet hole 102. The extension plate 4 is located inside the airflow conveying chamber 104, and one end of the extension plate 4 extends into the traction hole 105.

[0026] The extension plate 4 not only guides the yarn but also ensures its stability during ejection. Its position design allows airflow to act more effectively on the yarn, further enhancing the auxiliary traction and stabilization effect of the airflow and improving the quality and continuity of the fabric's stretch yarn.

[0027] Please see Figure 3 and Figure 4 A spiral blade 5 is provided on the outer side of the traction hole 105, and the spiral blade 5 is fixedly connected to the nozzle body 1.

[0028] The spiral blades 5 generate a spiral airflow, which can more fully wrap the yarn, providing a more uniform and stable traction force, effectively reducing the shaking and deviation of the yarn during the ejection process, and further improving the forming quality and continuity of the fabric stretch yarn.

[0029] Please see Figure 2 and Figure 3 A ring groove is provided on one side of the nozzle body 1. An air jet ring box 3 is fixedly installed inside the ring groove of the nozzle body 1. An air jet ring port 302 is provided on one side end face of the air jet ring box 3. The air jet ring port 302 is inclined and tilted towards the middle direction.

[0030] The arrangement of the jet ring box 3 and the jet ring nozzle 302 provides additional airflow support to the nozzle, enhancing the auxiliary traction and stabilization effect of the airflow, which helps to improve the quality of the fabric drawing yarn.

[0031] Please see Figure 1 The front end of the jet ring box 3 is provided with an air inlet 2 301, and the air inlet 2 301 is connected to the jet ring box 3. The front end of the nozzle body 1 is provided with an air inlet 106, and the air inlet 106 is connected to the airflow ring cavity 103.

[0032] The design of air inlet 106 and air inlet 2 301 facilitates connection to external air supply equipment via connectors and pipes, providing a stable airflow and increasing practicality.

[0033] Please see Figure 2 The inner diameter of the input cavity 101 gradually decreases from left to right.

[0034] The gradually decreasing inner diameter of the input cavity 101 can gradually increase the pressure of the yarn during the ejection process, which helps the yarn to fit more tightly into the yarn outlet and spinneret, reduces the shaking and deviation of the yarn during the ejection process, and improves the forming quality of the fabric stretch yarn.

[0035] Please see Figure 1 An mounting ring plate 2 is fixedly installed on one end of the outer side of the nozzle body 1. The mounting ring plate 2 has a mounting through hole 201 inside, and there are multiple mounting through holes 201 arranged in a ring at intervals.

[0036] The mounting ring plate 2 and the mounting through hole 201 facilitate the installation of the nozzle body 1 on the production equipment, increasing its practicality.

[0037] Working principle: During use, an external air supply device delivers airflow to the airflow annular cavity 103 through air inlet 106, while another external air supply device supplies air to the jet ring box 3 through air inlet 301. The molten raw material of the fabric drawing yarn enters the input cavity 101 of the nozzle through the extrusion device. As the inner diameter of the input cavity 101 gradually decreases, the pressure of the raw material gradually increases during its journey, tightly fitting the yarn outlet 102 and the spinneret 401 on the extension plate 4 connected thereto, ensuring stable yarn ejection. At this time, the airflow in the airflow annular cavity 103 flows to the traction hole 105 through the airflow conveying cavity 104. Inside the traction hole 105, the fixedly connected spiral blades 5 cause the airflow to generate a spiral flow. The spiral airflow wraps around the ejected yarn, providing uniform and stable traction force. When ejected, the airflow in the jet ring box 3 is ejected through the jet ring 302 tilted towards the center, providing additional airflow support, thereby increasing the forming quality and continuity of the fabric drawing yarn.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
