Description

Technical Field

[0001] This invention relates to the field of textile machinery, and more particularly to a textile bag spinning machine. Background Technology

[0002] As is known, the structure of existing textile machines generally consists of main parts such as a traction mechanism, a distribution mechanism, an air spinning device, a skeining mechanism, and a winding mechanism. The traction mechanism, being a pre-processor, typically consists of one or more pairs of rollers used to draw the fiber bundle to the air spinning device. The air spinning device generally includes a spinning chamber, a yarn guide shaft, a heating module, and airflow nozzles. The fiber bundle is drawn into the spinning chamber, where a swirling airflow from the nozzles twists the fiber bundle to form the yarn to be woven into the textile bag. To ensure the twisted yarn enters the inner hole of the shaft, a guide is used. The yarn drawn from the yarn guide shaft can be wound onto a temporary winding roller, awaiting processing in subsequent steps.

[0003] Existing textile machines with air-jetting devices suffer from the following problems during operation: Firstly, because the nozzles in existing technologies are generally arranged radially along the return channel, the airflow ejected into the airflow channel is guided by the channel wall to form a high-speed swirling airflow, requiring a relatively long cycle. To address this, a Chinese patent (CN203977041U, publication date 2014-12-03) proposes a textile bag spinning machine where the air nozzle extends axially into the reversing chamber (equivalent to the aforementioned airflow channel). The reversing chamber rotates to guide the ejected airflow to form the high-speed swirling airflow. While this method can reduce the cycle of high-speed swirling airflow formation to some extent, the increased number of components such as the rotating wheel and the reversing chamber drive structure also increases equipment costs. Secondly, existing guides generally use a needle-type structure. When guiding the twisted yarn into the central axis, this type of guide generates significant friction with the fiber bundle surface, leading to yarn damage. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a textile bag spinning machine that has the advantage of being able to quickly generate high-speed swirling airflow in the swirl channel to twist the fiber bundle, thereby improving the efficiency of yarn generation.

[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows:

[0006] A textile bag spinning machine includes a traction roller, an air spinning device, and a take-up unit. The air spinning device includes a fixed sleeve, a yarn guide mandrel, a spinning chamber, a heat-conducting jacket, a heating module, an air-jet module, and a fiber bundle guide. The yarn guide mandrel is coaxially disposed within the fixed sleeve, and a central channel penetrating the shaft along the axial direction is provided within the yarn guide mandrel. Twisted yarn is output from the central channel to the take-up unit. The spinning chamber is located at the front end of the fixed sleeve along the fiber bundle conveying direction, and the heat-conducting jacket is located at the front end of the spinning chamber. The heat-conducting jacket contains... The walls form a swirling groove; one end of the yarn guide mandrel is opposite to the swirling groove; the heating module is adapted to heat the swirling groove through a heat-conducting jacket; the jetting module includes multiple jet nozzles distributed circumferentially along the swirling groove, each jet nozzle is arranged obliquely relative to the inner wall of the swirling groove, and the nozzle orifice is configured to face the inner cavity of the swirling groove; a sealing cover is provided at the front end of the heat-conducting jacket; the fiber bundle output from the traction roller passes through the sealing cover and is guided into the central channel by the fiber bundle guide; the fiber bundle guide is fixed on the sealing cover and one end of it extends into the swirling groove.

[0007] In the above technical solution, by arranging multiple jet nozzles in the jet module at an angle relative to the inner wall of the swirling groove, rather than along the radial or axial direction, and configuring the nozzle openings to face the inner cavity of the swirling groove, the airflow ejected from the nozzles pushes against each other along the circumference of the swirling groove, quickly forming a high-speed swirling airflow, thereby improving the efficiency of fiber bundle twisting to form yarn. At the same time, since no additional components such as the rotating wheel and reversing structure found in existing technologies are added, the equipment cost is not increased, thus saving on equipment costs.

[0008] To optimize the above technical solution, the following technical measures also need to be taken:

[0009] Preferably, the plurality of jet nozzles are evenly distributed at equal angles along the circumference of the swirl channel, and each jet nozzle is tilted at the same angle relative to the inner wall of the swirl channel.

[0010] Preferably, the jet module further includes a jet flow control valve, with multiple jet nozzles connected to the jet flow control valve, which is connected to an air source module. The jet flow control valve allows for precise control of the air volume emitted from the jet nozzles, enabling the use of appropriate airflow rates for different yarn twisting processes. This achieves efficient twisting while saving energy.

[0011] Preferably, multiple contact balls are provided at both ends of the inner wall of the central channel, and the contact balls can contact the twisted yarn in the central channel.

[0012] Preferably, the multiple contact balls at each end of the central channel are evenly distributed at equal angles along the circumference of the central channel.

[0013] Preferably, the heating module includes multiple heating rods disposed on a heat-conducting jacket, the multiple heating rods being spaced apart along the circumference of the heat-conducting jacket. By setting and coordinating the heating rods and the heat-conducting jacket, the swirl groove is heated, thereby heating the fiber bundle to be twisted, causing the fibers to soften and unfold, thus facilitating subsequent splicing.

[0014] Preferably, the fiber bundle guide includes a yarn clamp rotatably connected to a heat-conducting jacket and a pull rod axially movable to a sealing cover plate. When pulled by the pull rod, the yarn clamp can hold the yarn and move the yarn toward one side of the central channel.

[0015] Preferably, the front end of the sealing cover is provided with a guide sleeve, one end of the pull rod extends into the guide sleeve and is connected to a first cam, one end of the guide sleeve is connected to a damping shaft, one end of the damping shaft extends into the guide sleeve and is connected to a second cam, the first cam and the second cam are adapted to each other, and a return spring is connected between the first cam and the pull rod.

[0025] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0026] Example 1:

[0027] Please see Figures 1 to 2This application provides a textile bag spinning machine, including a traction roller 1, an air spinning device 2, and a take-up unit 3. The air spinning device 2 includes a fixed sleeve 21, a yarn 5 guide mandrel 26, a spinning chamber 22, a heat-conducting jacket 23, a heating module, an air jet module, and a fiber bundle guide 4. The yarn 5 guide mandrel 26 is coaxially disposed within the fixed sleeve 21, and a central channel 261 is provided within the yarn 5 guide mandrel 26, penetrating the shaft axially. The twisted yarn 5 is output from the central channel 261 to the take-up unit 3. The spinning chamber 22 is disposed at the front end of the fixed sleeve 21 along the fiber bundle conveying direction. The heat-conducting jacket 23 is disposed at the front end of the spinning chamber 22, and the inner walls of the heat-conducting jacket 23 form a spiral. The swirling channel 231 has one end of the yarn 5 guide mandrel 26 opposite to it. The heating module 24 is adapted to heat the swirling channel 231 through the heat-conducting jacket 23. The jetting module includes a plurality of jet nozzles 28 distributed circumferentially along the swirling channel 231. Each jet nozzle 28 is inclined relative to the inner wall of the swirling channel 231, preferably at an angle of 25-30°, and the mouth of the jet nozzle 28 is configured to face the inner cavity of the swirling channel 231. A sealing cover plate 27 is provided at the front end of the heat-conducting jacket 23. The fiber bundle output from the traction roller 1 passes through the sealing cover plate 28 and is guided into the central channel 261 by the fiber bundle guide 4. The fiber bundle guide 4 is fixed on the sealing cover plate 28 and one end of it extends into the swirling channel 231. Preferably, the plurality of jet nozzles 28 are evenly distributed at equal angles along the circumferential direction of the swirling channel 231, and the angle of inclination of each jet nozzle 28 relative to the inner wall of the swirling channel 231 is the same.

[0028] Combination Figure 3 As shown, in the above embodiment, the traction roller 1 includes a left roller and a right roller arranged opposite each other. The untwisted fiber bundle passes through the gap between the left roller and the right roller and is drawn and conveyed to the air spinning device 2 by the traction roller 11. The take-up unit 3 can also be replaced by a storage roller. In the above embodiment, by arranging multiple air nozzles 28 in the air jet module at an angle relative to the inner wall of the swirl channel 231, rather than arranging them radially or axially, and by configuring the nozzles 28 orifices to face the inner cavity of the swirl channel 231, the airflow ejected by the air nozzles 28 pushes each other along the circumference of the swirl channel 231, thereby quickly forming a high-speed swirling airflow, which improves the efficiency of twisting the fiber bundle to form yarn 5. At the same time, since no additional components such as the rotating wheel and reversing structure of the prior art are provided, the equipment cost is not increased, that is, the equipment cost is saved.

[0029] refer to Figure 1As shown, in this embodiment, the jet module also includes a jet flow control valve 25, and multiple jet nozzles 28 are connected to the jet flow control valve 25, which is connected to the air source module. The jet flow control valve 25 can precisely control the amount of air ejected from the jet nozzles 28, allowing for the use of appropriate airflow rates for different yarn twisting processes. This not only efficiently completes the twisting process but also saves energy.

[0030] Combination Figures 1 to 2 As shown, to prevent the yarn 5 from rubbing against the inner wall when entering or leaving the central channel 261, multiple contact balls 262 are provided at both ends of the inner wall of the central channel 261. These contact balls 262 can contact the twisted yarn 5 within the central channel 261. The multiple contact balls 262 at each end of the central channel 261 are evenly distributed at equal angles along the circumference of the central channel 261. This configuration allows the multiple contact balls 262 to separate the conveying yarn 5 from the inner wall of the central channel 261, thereby preventing direct contact between the yarn 5 and the inner wall of the central channel, thus avoiding friction.

[0031] Combination Figure 2 As shown, the heating module includes multiple heating rods 24 disposed on a heat-conducting jacket 23, with the heating rods 24 spaced apart along the circumference of the heat-conducting jacket 23. Through the arrangement and cooperation of the heating rods 24 and the heat-conducting jacket 23, the swirl groove 231 is heated, thereby heating the fiber bundle to be twisted, softening and stretching the fibers, thus facilitating the subsequent twisting process. The heat-conducting jacket 23 is preferably made of aluminum alloy.

[0032] In this embodiment, to further address the problem of yarn 5 damage caused by needle-type guides in the prior art, the fiber bundle guide 4 in this embodiment includes a yarn clamping strip 41 rotatably connected to the heat-conducting jacket 23 and a pull rod 42 axially movable connected to the sealing cover plate 27. Under the pull of the pull rod 42, the yarn clamping strip 41 can clamp the yarn 5 and move the yarn 5 toward the central channel 261. Here, the rotating clamping or rotating locking structure is used in lever clamping cylinders or reverse clamping cylinders, which are conventional technologies and will not be elaborated here.

[0033] like Figure 2As shown, specifically, the front end of the sealing cover plate 27 is provided with a guide sleeve 43. One end of the pull rod 42 extends into the guide sleeve 43 and is connected to a first cam 44. One end of the guide sleeve 43 is connected to a damping shaft 47. One end of the damping shaft 47 extends into the guide sleeve 43 and is connected to a second cam 45. The cam slopes of the first cam 44 and the second cam 45 cooperate with each other. A return spring 46 is connected between the first cam 44 and the pull rod 42. Preferably, one end of the damping shaft 47 is provided with a driving member 48. The driving member 48 can be a self-locking rotary motor or a swing cylinder, etc., which is limited here. In use, the driving member 48 is opened, the damping shaft 47 rotates, the second cam 45 rotates and squeezes the first cam 44, and the pull rod 42 moves axially towards the central channel 461, driving the yarn clamping strip 41 to clamp or hold the twisted yarn and move towards the central channel 261, thereby guiding the yarn into the central channel 261.

[0034] In summary, in the above embodiments, by arranging the multiple jet nozzles 28 in the jet module at an angle relative to the inner wall of the swirl channel 231, rather than along the radial or axial direction, and configuring the openings of the jet nozzles 28 to face the inner cavity of the swirl channel 231, the airflow ejected from the jet nozzles 28 pushes each other along the circumference of the swirl channel 231, thereby quickly forming a high-speed swirling airflow, which improves the efficiency of twisting the fiber bundle to form yarn 5. At the same time, since no additional components such as the rotating wheel and reversing structure found in the prior art are provided, the equipment cost is not increased, thus saving equipment costs.

[0035] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
