Description

Technical Field

[0001] This utility model relates to the field of chemical fiber textile machinery technology, and in particular to a low flow resistance air deformation mechanism for air-deformed yarn production. Background Technology

[0002] Currently, in the industrial production of air-deformed yarn, the yarn is processed by equipment and blown open into several monofilaments. The free yarn segments are further processed and intertwined to form the basic structure of air-deformed yarn. Traditional equipment usually uses nozzles connected to air blowing pipes to blow the yarn apart.

[0003] Traditional equipment includes an air duct, an air blowing pipe, a wire feeding pipe, and a nozzle structure. Compressed air with a certain humidity is continuously delivered in the air duct. The nozzle structure is located inside the air duct and is connected to the air blowing pipe. The air blowing pipe is used to deliver high-pressure airflow into the nozzle structure. The wire feeding pipe is connected to the end of the nozzle structure where the airflow flows in and is used to deliver the wire to be processed into the nozzle structure. The wire enters the nozzle structure through the wire feeding pipe and is blown out along the nozzle structure by the airflow flowing in through the air blowing pipe.

[0004] Regarding the aforementioned technologies, the nozzle structure is connected to the wire feeding tube and the air blowing tube through multiple bends. During the airflow transmission process, airflow impact is easily formed at the bends, which causes local increases in air pressure and can easily lead to uneven airflow thrust on the wire, which is not conducive to the device performing uniform deformation processing on the wire. Utility Model Content

[0005] In order to enable the device to perform uniform deformation processing on the yarn, this application provides a low flow resistance air deformation mechanism for air-cured yarn production.

[0006] This application provides a low-flow-resistance air deformation mechanism for air-variable yarn production, employing the following technical solution: A low-flow-resistance air deformation mechanism for air-conditioned yarn production includes a nozzle body. One end of the nozzle body along its length has a yarn inlet for connecting to a yarn feeding tube. An air inlet 1 is formed on the outer surface of the nozzle body near the yarn inlet, for connecting to an air blowing tube. An annular channel 1 is formed circumferentially inside the nozzle body and communicates with the air inlet 1. An airflow channel is formed along the length of the nozzle body and communicates with the yarn inlet. Two air inlets 2 are formed radially parallel to the air inlet 1. The air inlets 1 and 2 are located on the same cross-section, and the diameter of each air inlet 2 is smaller than that of the air inlet 1. An annular channel 2 connects the two air inlets 2, and the annular channel 2 is coaxially arranged with the annular channel 1. The annular channel 2 communicates with the annular channel 1 on the side away from the air inlet 1.

[0007] By adopting the above technical solution, under the support of the nozzle body, the wire feeding tube feeds the wire into the wire inlet, and the air blowing tube delivers the airflow to air inlet one and air inlet two. Air inlet one and air inlet two disperse the airflow, making the airflow in air inlet two and air inlet one similar. The airflow in air inlet one enters the airflow channel through annular channel one, and the airflow in air inlet two enters annular channel one through annular channel two. This makes the airflow in the nozzle body uniformly dispersed radially, thereby making the airflow evenly blow the wire.

[0008] Optionally, the nozzle body includes an outer cylinder and an inner core, the outer cylinder being sleeved outside the inner core and being detachably connected, and the wire inlet being located inside the inner core.

[0009] By adopting the above technical solution, operators can replace and clean the inner core inside the outer cylinder, which helps to improve the cleaning convenience and applicability of the device.

[0010] Optionally, the cross-sectional diameter of the airflow channel gradually increases from the inlet to the end away from the inlet.

[0011] By adopting the above technical solution, the airflow channel provides a dispersion space for the separated filaments, reducing the probability of the dispersed filaments getting tangled together again.

[0012] Optionally, the air inlet is connected to an air inlet pipe. The end of the air inlet pipe away from the nozzle body is connected to an air blowing pipe. A baffle is provided at the end of the air inlet pipe away from the air inlet. The baffle is provided with opposing connecting pieces along the radial direction. A fixing groove is provided on the inner wall of the air inlet pipe along the circumferential direction. The inner wall of the fixing groove gradually approaches the axis of the air inlet pipe along the air intake direction. A guide groove for accommodating the connecting pieces is provided along the length of the air inlet pipe. The connecting pieces are inserted into the guide groove and slidably connected to the inner wall of the guide groove. A gap is left between the baffle and the inner wall of the fixing groove. An elastic element is provided between the connecting pieces and the inner wall of the fixing groove. One end of the elastic element is connected to the inner wall of the fixing groove, and the other end is connected to the connecting pieces. In its natural state, the elastic element has a tendency to push the baffle away from the nozzle body.

[0013] By adopting the above technical solution, the guide groove guides and limits the connecting piece, the fixed groove provides the baffle with moving space, and the airflow in the air inlet enters the air inlet along the gap between the baffle and the inner wall of the fixed groove. When the airflow velocity in the air inlet is too fast, the airflow pushes the baffle to move towards the air inlet. The elastic element provides the baffle with moving space, the baffle blocks the airflow, and the gap between the baffle and the inner wall of the fixed groove gradually decreases, reducing the airflow velocity and the airflow into the air inlet, thereby reducing the probability of the airflow impacting the elbow and causing excessive local pressure, so that the airflow can evenly disperse the wire.

[0014] Optionally, a pressure relief hole is opened on the side of the inner wall of the fixing groove away from the nozzle body. In the natural state of the elastic element, the connecting piece is directly opposite the pressure relief hole, and the diameter of the connecting piece is larger than the maximum diameter of the pressure relief hole.

[0015] By adopting the above technical solution, when the airflow velocity is too fast, the pressure relief hole disperses the airflow, thereby reducing the impact of the airflow on the baffle and reducing the impact of the airflow on the baffle, so that the airflow velocity flowing into the nozzle body is matched with the airflow velocity required by the wire.

[0016] Optionally, the diameter of the baffle cross-section gradually decreases from the direction of the air blowing pipe toward the nozzle body.

[0017] By adopting the above technical solution, the airflow is blocked by increasing the contact area between the baffle and the airflow, thereby reducing the airflow velocity and reducing the noise generated by the airflow contacting the elbow during the processing.

[0018] Optionally, the baffles have a uniform cross-sectional diameter, and the side of the baffles closest to the nozzle body is provided with several protrusions along the circumference, with the protrusions facing the inner wall of the fixing groove closest to the nozzle body.

[0019] By adopting the above technical solution, when the airflow pushes the baffle closer to the air inlet, the protrusion contacts the inner wall of the fixed groove, leaving a gap between the inner wall of the fixed groove and the baffle, providing space for the airflow to pass through.

[0020] Optionally, the baffle has an arc-shaped surface on the side near the air blowing pipe, and the arc-shaped surface is concave in the direction of airflow transmission.

[0021] By adopting the above technical solution, the baffle increases the contact area with the airflow through the arc surface, thereby improving the efficiency of the airflow in driving the baffle.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Under the support of the nozzle body, the wire feeding tube feeds the wire into the wire inlet, and the air blowing tube delivers airflow to air inlet one and air inlet two. Air inlet one and air inlet two disperse the airflow, making the airflow in air inlet two and air inlet one similar. The airflow in air inlet one enters the airflow channel through annular channel one, and the airflow in air inlet two enters annular channel one through annular channel two. This makes the airflow in the nozzle body radially dispersed evenly, thereby making the airflow evenly blow away the wire. 2. Operators can replace and clean the inner core inside the outer cylinder, which helps improve the ease of cleaning and applicability of the device; 3. The airflow channel provides space for the separated filaments to disperse, reducing the probability of the dispersed filaments getting tangled together again. Attached Figure Description

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses a low-flow-resistance air deformation mechanism for the production of air-cured yarn. Example

[0031] Reference Figure 1 and Figure 2 A low-flow-resistance air deformation mechanism for air-conditioned yarn production includes a nozzle body 1. The nozzle body 1 includes an outer cylinder 11 and an inner core 12, which are coaxially arranged. The inner core 12 is inserted into the outer cylinder 11 and detachably connected to it. An inlet 121 is formed along the length of the inner core 12 for connection to a yarn feeding tube. An airflow channel 113 communicating with the inlet 121 is formed along the length of the outer cylinder 11. The yarn enters the airflow channel 113 through the inlet 121. The cross-sectional diameter of the airflow channel 113 gradually increases along the yarn entry direction, providing space for the yarn to disperse and reducing the probability of the yarn re-entanglement after dispersion. The outer cylinder 11 supports the inner core 12, which helps improve the working stability of the inner core 12.

[0032] Reference Figure 2 and Figure 3A gap is left between the outer cylinder 11 and the inner core 12 to form an annular channel 111. The outer cylinder 11 has an air inlet 114 connected to the annular channel 111 and two air inlets 115 parallel to the air inlet 114, which are used to connect to the air blowing pipe. An annular channel 112 coaxial with the annular channel 111 is opened inside the outer cylinder 11. The diameter of the annular channel 112 is larger than that of the annular channel 111. The annular channel 112 is connected to both air inlets 115. The side of the annular channel 112 away from the air inlets 115 is connected to the annular channel 111.

[0033] Reference Figure 2 and Figure 3 The airflow in the blowing pipe enters the annular channels 111 and 112 respectively through inlet 114 and inlet 115. The airflow in annular channel 112 enters annular channel 111 and then enters airflow channel 113 to disperse the yarn. Inlet 114 and inlet 115 disperse the airflow. The diameter of inlet 115 is smaller than that of inlet 114, making the airflow entering inlet 114 and inlet 115 approximately the same. This results in the airflow entering annular channel 111 and annular channel 112 being approximately the same, thus ensuring that the airflow evenly disperses the yarn along the circumference of the outer cylinder 11.

[0034] Reference Figure 3 and Figure 4 Air inlet 114 and air inlet 115 are connected by an air intake pipe 2. A fixed groove 21 is formed along the circumference of the air intake pipe 2. The inner wall of the fixed groove 21 gradually approaches the axis of the air intake pipe 2 along the airflow inlet direction. A baffle 3 is slidably connected within the fixed groove 21, and the cross-sectional diameter of the baffle 3 gradually decreases along the airflow inlet direction. Two opposing connecting pieces 32 are provided along the circumference of the baffle 3. A guide groove 23 for accommodating the connecting pieces 32 is formed along the length of the fixed groove 21. The guide groove 23 guides and limits the displacement of the connecting pieces 32 along the length of the air intake pipe 2, thereby allowing the air intake pipe 2 to guide and limit the displacement of the baffle 3 along the length of the air intake pipe 2 through the connecting pieces 32.

[0035] Reference Figure 3 and Figure 4An elastic element 31 is provided between the connecting piece 32 and the fixing groove 21. The elastic element 31 can be a spring. One end of the spring is connected to the inner wall of the fixing groove 21, and the other end is connected to the connecting piece 32. In its initial state, the spring has a tendency to push the connecting piece 32 away from the outer cylinder 11. When the airflow in the blowing pipe is transmitted to the air inlet 114, the airflow pushes the baffle 3 closer to the air inlet 114 and flows along the gap between the baffle 3 and the inner wall of the air inlet pipe 2. When the airflow velocity is too fast, the baffle 3 gradually approaches the air inlet 114, making the gap between the baffle 3 and the inner wall of the air inlet pipe 2 smaller and smaller, thereby reducing the airflow velocity and the airflow rate into the air inlet pipe 2, and thus reducing the noise caused by the contact between the airflow velocity and the elbow.

[0036] Reference Figure 1 and Figure 4 The intake pipe 2 has a pressure relief hole 22 radially opened on the side away from the intake port. In the initial state, the connecting piece 32 is directly opposite the pressure relief hole 22. When the airflow velocity is too high, the connecting piece 32 moves closer to the intake port, so that the airflow flows out from the pressure relief hole 22, thereby reducing the airflow velocity and flow rate, reducing the impact of the airflow on the baffle 3, and finally reducing the noise caused by the excessive airflow velocity contacting the elbow.

[0037] The implementation principle of the low flow resistance air deformation mechanism for air-changing yarn production in this application embodiment is as follows: the feeding tube delivers yarn to the inlet 121, and the blowing tube transmits airflow into the inlet pipe 2. The airflow enters the first inlet 114 and the second inlet 115 along the gap between the baffle 3 and the inner wall of the inlet pipe 2. When the airflow velocity is too fast, it pushes the baffle 3 closer to the inlet, thereby reducing the gap and reducing the airflow velocity and flow rate, reducing the noise generated by the airflow contacting the bend. The first inlet 114 and the second inlet 115 split the airflow, making the flow rate in the second inlet 115 and the first inlet 114 approximately the same, thereby making the airflow flow rate in the first annular channel 111 and the second annular channel 112 approximately the same. The airflow in the second annular channel 112 enters the first annular channel 111, so that the outer cylinder 11 blows the yarn evenly.

[0038] Example 2 The difference between this embodiment and embodiment 1 is that the outer diameter of the baffle 3 is the same at any point.

[0039] Reference Figure 3 and Figure 5The baffle 3 has an arc-shaped surface 34 on the side opposite to the air inlet. The arc-shaped surface 34 is concave along the airflow direction, which increases the contact area between the airflow and the baffle 3, thereby improving the ease with which the airflow can move the baffle 3. Multiple protrusions 33 are installed on the side of the baffle 3 near the air inlet 114. The protrusions 33 are directly opposite the inner wall of the fixing groove 21 near the air inlet 114. When the airflow velocity is too high, it pushes the baffle 3 closer to the air inlet 114, and the protrusions 33 contact the inner wall of the fixing groove 21, ensuring that there is always a gap between the inner wall of the fixing groove 21 and the baffle 3 for airflow to pass through, which helps to improve the continuity of airflow transmission.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
