Description

Technical Field

[0001] This application relates to the technical field of textile equipment, and in particular to a jet vortex spinning machine. Background Technology

[0002] The air-jet vortex spinning machine is a highly efficient spinning device that primarily uses nozzles to accelerate airflow, creating a high-speed swirling airflow field within the twister. Within this high-speed swirling airflow field, the fed fibers are twisted to form yarn. Compared to traditional spinning methods, the air-jet vortex spinning machine does not require high-speed rotating mechanical components, and is therefore considered one of the best spinning methods.

[0003] An existing air-jet vortex spinning machine first feeds a combed fiber sliver into the feeding device, where it is separated into finer fiber bundles. These bundles then enter the spinning nozzle along a spiral fiber guide channel under the influence of axial airflow at the nozzle inlet. Inside the nozzle, the high-speed jet of air (usually air) creates a powerful vortex field. Upon entering this vortex, the fiber bundles are accelerated and rotated by the airflow, causing intense entanglement between the fibers. Under the influence of the airflow, the fibers coalesce at the center of the vortex and gradually form a yarn. During this process, friction and electrostatic forces between the fibers help them become entangled, forming a yarn with a certain structural strength. The final yarn is then guided to a winding device and wound onto a bobbin at a set speed and tension to form the finished yarn.

[0004] However, existing jet vortex spinning machines tend to generate noise during spinning due to vibration and airflow acceleration. This constitutes noise pollution for operators within a certain range of the spinning machine, and in severe cases, it may affect the normal operation of the spinning machine. Summary of the Invention

[0005] In order to reduce the noise emitted during the spinning process of a spinning machine, this application provides an air jet vortex spinning machine.

[0006] This application provides a jet vortex spinning machine, which adopts the following technical solution:

[0007] A jet vortex spinning machine, comprising

[0008] Organism;

[0009] A soundproof cover has a soundproof cavity, the machine body is located inside the soundproof cavity, and a soundproof panel is provided inside the soundproof cover;

[0010] Multiple buffer water bags are disposed on the inner wall of the soundproof cover. The buffer water bags are located inside the soundproof cavity and abut against the outer wall of the machine body.

[0011] A noise sensor is installed in the soundproof cover and located inside the soundproof cavity;

[0012] A control system is installed in the soundproof enclosure and connected to the noise sensor;

[0013] When the noise sensor detects an increase in noise intensity inside the soundproof cavity, the control system controls the water pressure inside the buffer water bladder to increase.

[0014] When the noise sensor detects a decrease in noise intensity within the soundproof cavity, the control system controls the water pressure within the buffer water bladder to decrease.

[0015] By adopting the above technical solutions, the jet vortex spinning machine effectively isolates the noise generated by the machine body and reduces noise pollution in the working environment through the design of soundproof covers and soundproof panels. Simultaneously, the inclusion of a buffer water bladder further absorbs and reduces noise within the soundproof cavity. Through the cooperation of noise sensors and a control system, dynamic adjustment of noise intensity is achieved. When noise increases, the control system increases the water pressure within the buffer water bladder to enhance its sound absorption effect; when noise decreases, the water pressure decreases to extend the service life of the buffer water bladder.

[0016] Optionally, the control system includes a water tank, a control pump, a control valve, and a controller;

[0017] The water tank is disposed on the outer wall of the soundproof cover, and a water tank is formed inside the water tank. The control pump is disposed in the water tank and located inside the water tank.

[0018] Water supply pipes are respectively connected between adjacent buffer water tanks, water inlet pipe is connected to and fixed to the water inlet of the control pump, and water outlet pipe is connected to and fixed to the water outlet of the control pump.

[0019] The water inlet pipe is connected to a first pipe and a second pipe on the side away from the control pump. The first pipe is connected to the buffer water bag, and the second pipe is connected to the water tank.

[0020] The outlet pipe is connected to a third pipe and a fourth pipe on the side away from the control pump. The third pipe is connected to the buffer water bag, and the fourth pipe is connected to the water tank.

[0021] The controller is located in the water tank, and is electrically connected to the noise sensor and the control pump.

[0022] The control valves are multiple and are respectively disposed in the first pipe body, the second pipe body, the third pipe body and the fourth pipe body, and the controller is electrically connected to the control valves;

[0023] When the noise inside the soundproof cavity increases, the controller controls the first pipe to close, the second pipe to open, the third pipe to open, and the fourth pipe to close via the control valve.

[0024] When the noise in the soundproof cavity is reduced, the controller controls the first pipe to open, the second pipe to close, the third pipe to close, and the fourth pipe to open via the control valve.

[0025] By adopting the above technical solution, the control system achieves dynamic adjustment of the water pressure inside the buffer water bladder through the coordinated operation of the water tank, control pump, control valve, and controller. This design not only improves the system's response speed but also ensures the accuracy and stability of noise regulation. By setting up inlet and outlet pipes and multiple control valves, flexible water flow scheduling is achieved, ensuring that the buffer water bladder can quickly adapt and exert its optimal sound absorption effect under different noise intensities.

[0026] Optionally, the outer wall of the water supply pipe is provided with an installation block, and the installation block and the water supply pipe form an interconnected installation groove;

[0027] The mounting block is rotatably connected to a rotating shaft, and multiple rotating blades extending into the water supply pipe are evenly spaced along the outer periphery of the rotating shaft.

[0028] The rotating shaft extends away from the mounting block to the side wall of the soundproof cover, and a plurality of fan blades located outside the mounting groove are evenly spaced on the outer periphery of the rotating shaft.

[0029] The soundproof cover has vents on its sidewalls that face the fan blades.

[0030] By adopting the above technical solution, the mounting block and rotating shaft design on the water pipe cause the rotating blades to rotate under the influence of noise within the soundproof chamber, thereby driving the fan blades to rotate and generate airflow. This design not only enhances airflow within the soundproof enclosure, aiding in heat dissipation and further reducing noise, but also improves the equipment's heat dissipation performance. The design of the fan blades and vents allows airflow to be directly discharged from the soundproof enclosure, reducing the possibility of eddies or heat accumulation inside, further optimizing the working environment.

[0031] Optionally, the soundproof cover is provided with sound-absorbing cotton located inside the air vents.

[0032] By adopting the above technical solution and placing sound-absorbing cotton inside the air pores, the sound absorption effect of the soundproof cover is further enhanced, effectively reducing the transmission and reflection of noise and improving the overall noise reduction performance.

[0033] Optionally, the soundproof cover is movably connected to the machine body, and the soundproof cover is connected to the ground.

[0034] By adopting the above technical solutions, the movable connection design between the soundproof enclosure and the machine body reduces the direct impact of machine vibration on the soundproof enclosure. Simultaneously, the soundproof enclosure can be easily installed or removed as needed, facilitating machine maintenance and upkeep. The connection design between the soundproof enclosure and the ground ensures its stability, reducing noise leakage or equipment damage caused by machine vibration.

[0035] Optionally, the soundproof enclosure includes an enclosure body and a sealing plate, the sealing plate being hinged to the side wall of the enclosure body, the enclosure body being provided with a fixing member, and the sealing plate being detachably fixed to the enclosure body.

[0036] By adopting the above technical solution, the hinged design of the soundproof enclosure's body and sealing plate allows the sealing plate to open and close flexibly, facilitating cleaning or maintenance of the interior of the soundproof enclosure. The design of the fasteners ensures that the sealing plate is firmly fixed to the enclosure body when closed, guaranteeing the soundproof enclosure's sealing performance and noise reduction effect.

[0037] Optionally, the fixing component includes a fixing lock that connects the sealing plate and the cover.

[0038] By adopting the above technical solution, the fixed lock, as a way of fixing components, has a simple structure and is easy to operate. It can quickly lock the sealing plate onto the cover, thereby improving the safety and reliability of the equipment.

[0039] Optionally, the sealing plate is provided with a sound insulation ring, and when the sealing plate seals the cover, the sound insulation ring abuts against the cover.

[0040] By adopting the above technical solution, the sound-insulating ring design on the sealing plate can provide additional sound insulation when the sealing plate is in contact with the enclosure, further reducing noise leakage and propagation. At the same time, the sound-insulating ring also acts as a buffer and seal, extending the service life of the equipment.

[0041] In summary, this application includes at least one of the following beneficial effects:

[0042] 1. The jet vortex spinning machine effectively isolates the noise generated by the machine body through the design of soundproof covers and soundproof panels, reducing noise pollution in the working environment. At the same time, the setting of buffer water bladder can further absorb and reduce the noise in the soundproof cavity. Through the cooperation of noise sensors and control systems, dynamic adjustment of noise intensity is achieved.

[0043] 2. The mounting blocks and rotating shaft design on the water supply pipe cause the rotating blades to rotate under the influence of noise within the soundproof chamber, thereby driving the fan blades to rotate and generate airflow. This design not only enhances airflow within the soundproof enclosure, aiding in heat dissipation and further reducing noise, but also improves the equipment's heat dissipation performance.

[0050] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0051] This application discloses an air-jet vortex spinning machine. See also... Figure 1 and Figure 2The jet-jet vortex spinning machine includes a machine body 1, which includes a feeding device, spinning nozzles, and a winding device. During spinning, the combed fiber sliver is first fed into the feeding device of the jet-jet vortex spinning machine, where it is separated into finer fiber bundles. Then, under the action of axial airflow at the inlet of the spinning nozzle, the fiber bundles enter the spinning nozzle along a spiral fiber guide channel. Inside the spinning nozzle, the high-speed jet of air (usually air) forms a powerful vortex field. After entering the vortex field, the fiber bundles are accelerated and rotated by the airflow, causing strong entanglement between the fibers. Then, under the action of the airflow, the fibers coalesce at the center of the vortex and gradually form a yarn. During this process, the friction and electrostatic effects between the fibers help them entangle together, forming a yarn with a certain structural strength. The finally formed yarn is then guided to the winding device and wound onto a bobbin at a set speed and tension to form the finished yarn. The spinning technology of machine body 1 is existing technology and will not be described in detail here.

[0052] See Figure 2 and Figure 3 The jet vortex spinning machine also includes a soundproof cover 2, which forms a soundproof cavity 23. The machine body 1 is located inside the soundproof cavity 23. The soundproof cover 2 covers the machine body 1. A soundproof plate 24 is embedded and fixed in the side wall of the soundproof cover 2, so that the soundproof plate 24 can reduce the noise generated by the machine body 1 during spinning.

[0053] The soundproof enclosure 2 includes an enclosure body 21 and a sealing plate 22. The enclosure body 21 is movably connected to the machine body 1 and is fixed to the ground by fixing bolts, reducing the possibility of vibrations generated by the machine body 1 during spinning being directly transmitted to the enclosure body 21. An opening is formed on one vertical side wall of the enclosure body 21, which connects to the soundproof cavity 23, allowing the operator to operate the machine body 1 through the opening. The sealing plate 22 is hinged to the side wall of the enclosure body 21 and is used to seal the opening. The sealing plate 22 is fitted with a sound-insulating ring 9 with a fixed annular structure. When the sealing plate 22 is flipped to abut against the enclosure body 21, the sealing plate 22 seals the opening, reducing the intensity of noise emitted from the opening; at the same time, the sound-insulating ring 9 abuts against the enclosure body 21 and surrounds the opening, reducing the intensity of noise emitted between the sealing plate 22 and the enclosure body 21.

[0054] See Figure 1 The cover 21 has a fixing component, and the sealing plate 22 is detachably fixed to the cover 21. The fixing component includes a fixing lock 8, which includes a lock head and accessories. The accessories are respectively connected to the outer wall of the sealing plate 22 and the cover 21, and the lock head is connected to the accessories, so that the sealing plate 22 and the cover 21 are connected and fixed.

[0055] See Figure 2 and Figure 3The jet vortex spinning machine also includes a buffer water bladder 3, which is fixed to the cover 21. Multiple buffer water bladders 3 are located on the periphery and the inner top wall of the cover 21. The buffer water bladder 3 is in contact with the outer wall of the machine body 1. The buffer water bladder 3 is made of a material with elastic deformation capabilities, such as rubber or silicone, and is filled with water. When the machine body 1 vibrates during spinning, the buffer water bladder 3 comes into contact with it. The vibration acts on the buffer water bladder 3, and the water flow buffers the vibration, reducing the noise generated by the vibration of the machine body 1. Simultaneously, the water flow inside the buffer water bladder 3 absorbs the heat generated during spinning in the sound insulation cavity 23, thus dissipating heat from the machine body 1.

[0056] See Figure 3 and Figure 4 The jet vortex spinning machine also includes a noise sensor 4 and a control system 5. The noise sensor 4 is installed and fixed in the cover 21 and located inside the sound insulation cavity 23. During use, the noise sensor 4 receives and senses the noise intensity inside the sound insulation cavity 23, which is beneficial for monitoring the noise intensity generated during spinning.

[0057] The control system 5 is installed on the soundproof enclosure 2. The control system 5 includes a water tank 51, a control pump 52, a control valve 53, and a controller 54. The water tank 51 is detachably fixed to the outer wall of the soundproof enclosure 2 and is in contact with the ground. A water trough 511 is formed inside the water tank 51, and water is stored in the water trough 511. The weight of the water tank 51 acts on the soundproof enclosure 2, which can further improve the stability of the soundproof enclosure 2.

[0058] The control pump 52 is fixed to the water tank 51 and located inside the water trough 511. In this embodiment, the control pump 52 is a submersible pump. The control pump 52 is fixedly connected to an inlet pipe 6, which communicates with the inlet of the control pump 52. The control pump 52 is also fixedly connected to an outlet pipe 7, which communicates with the outlet of the control pump 52. When the control pump 52 starts, the inlet pipe 6 draws water and transmits it to the control pump 52, which then outputs the water from the outlet pipe 7.

[0059] The inlet pipe 6, on the side away from the control pump 52, is connected and fixed with a first pipe body 61 and a second pipe body 62. The first pipe body 61 passes through and is fixed to the soundproof cover 2, and is connected and fixed to the buffer water bladder 3 located on the top cavity wall of the soundproof cavity 23. The second pipe body 62 is connected to the water tank 511, and the second pipe body 62 extends downward, so that the pipe opening on the side of the second pipe body 62 away from the inlet pipe 6 is located at the bottom of the water tank 511.

[0060] The outlet pipe 7 is connected to and fixed with a third pipe 71 and a fourth pipe 72 on the side away from the control pump 52. The third pipe 71 is connected to and fixed with a buffer water bladder 3 facing the water tank 51. The fourth pipe 72 is connected to the water tank 511. The fourth pipe 72 extends downward so that the opening of the fourth pipe 72 away from the outlet pipe 7 is located at the bottom of the water tank 511.

[0061] The controller 54 is fixedly connected to the side wall of the water tank 51. The controller 54 is electrically connected to the noise sensor 4 and the control pump 52. The controller 54 can control the control pump 52 to start according to the noise intensity change in the sound insulation cavity 23 sensed by the noise sensor 4.

[0062] See Figure 4 and Figure 5 The controller 54 is electrically connected to the control valve 53, and water supply pipes 31 are fixedly connected between adjacent buffer water bags 3. There are multiple control valves 53, which are fixed on the first pipe body 61, the second pipe body 62, the third pipe body 71 and the fourth pipe body 72 respectively. The controller 54 can control the opening and closing status of the first pipe body 61, the second pipe body 62, the third pipe body 71 and the fourth pipe body 72 by controlling the opening and closing of the control valves 53.

[0063] See Figure 2 and Figure 4 When the noise sensor 4 detects an increase in noise within the soundproof cavity 23, it transmits the sensing result to the controller 54 via a wireless signal. The controller 54 then controls the opening and closing of each control valve 53. At this time, control valve 53 closes the first pipe 61, opens the second pipe 62, opens the third pipe 71, and closes the fourth pipe 72. Simultaneously, the controller 54 starts the control pump 52. The second pipe 62 draws water from the water tank 511 and transmits it to the control pump 52. The control pump 52 then pumps the water into the buffer water bladder 3 through the third pipe 71, increasing the water pressure within the buffer water bladder 3 to accommodate the vibration intensity of the machine body 1 and improve the buffering effect of the buffer water bladder 3 on the vibration of the machine body 1. When the noise sensor 4 detects that the noise intensity within the soundproof cavity 23 is stable, the controller 54 shuts down the control pump 52.

[0064] When the noise sensor 4 detects a decrease in noise within the soundproof cavity 23, it transmits the sensing result wirelessly to the controller 54. The controller 54 then controls the opening and closing of each control valve 53. At this time, control valve 53 controls the opening of the first pipe 61, the closing of the second pipe 62, the closing of the third pipe 71, and the opening of the fourth pipe 72. Simultaneously, the controller 54 starts the control pump 52. The first pipe 61 draws water from the buffer water bladder 3 and transmits it to the control pump 52. The control pump 52 then pumps the water into the water tank 511 through the fourth pipe 72, causing a decrease in water pressure within the buffer water bladder 3. This reduces the water pressure within the buffer water bladder 3, allowing it to adapt to the vibration intensity of the machine body 1, reducing the high-pressure expansion state of the buffer water bladder 3 and extending its service life. Furthermore, as the water flows from the buffer water bladder 3 into the water tank 511, the absorbed heat is carried into the water tank 511, reducing the heat within the soundproof cavity 23.

[0065] See Figure 5 An installation block 32 is fixedly connected to the outer wall of the water supply pipe 31. The installation block 32 and the wall of the water supply pipe 31 each have interconnected installation grooves 321, which are connected to the water supply pipe 31. A rotating shaft 33 is rotatably connected to the installation block 32. Rotating blades 331 extending into the water supply pipe 31 are fixedly connected to the outer periphery of the rotating shaft 33. Multiple rotating blades 331 are evenly spaced circumferentially. When water flows through the water supply pipe 31, the water impacts the rotating blades 331, causing the rotating shaft 33 to rotate.

[0066] See Figure 4 and Figure 5 One end of the rotating shaft 33 extends away from the mounting block 32 to a position near the side wall of the soundproof cover 2. Multiple fan blades 332 are fixedly connected to the outer periphery of the rotating shaft 33 and are evenly spaced. Multiple air holes 25 are formed on the side wall of the soundproof cover 2 and are directly opposite the fan blades 332. When the control pump 52 fills the buffer water bladder 3 with water, the water flows through the water supply pipe 31, causing the rotating shaft 33 to rotate forward. At this time, the fan blades 332 rotate, generating an airflow towards the airflow. The airflow flows through the air holes 25 and then to the outside of the soundproof cavity 23, which helps to transfer heat to the outside of the soundproof cavity 23, further improving the soundproof performance of the body 1 (body 1 in...). Figure 3 The heat dissipation effect (as indicated by the winning bid).

[0067] The soundproof cover 2 is fixedly connected with sound-absorbing cotton 26, which is located inside the vents 25, with each vent 26 corresponding to a specific vent 25. The sound-absorbing cotton 26 can be made of open-cell foam plastic; in other embodiments, it can also be made of polyester fiber, glass fiber, etc. During use, the sound-absorbing cotton 26 reduces the noise intensity passing through the vents 25, while allowing airflow to pass through them.

[0068] The implementation principle of a jet vortex spinning machine according to an embodiment of this application is as follows:

[0069] During spinning, the machine body 1 generates noise. At this time, the sound insulation plate 24 inside the sound insulation cover 2 absorbs and blocks the spread of noise, reducing the noise intensity. At the same time, the buffer water bag 3 comes into contact with the machine body 1 to buffer the vibration generated by the machine body 1 during spinning, further reducing the noise intensity generated during spinning.

[0070] 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.
