Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for spinning equipment, specifically to an online cleaning device for spinning air ducts. Background Technology

[0002] A spinning air duct is a component of the textile industry used in the fiber manufacturing process. It is typically installed on a spinning machine, particularly in the production of chemical fibers such as polyester and nylon. The main function of the spinning air duct is to provide a uniform airflow to aid in fiber cooling, straightening, and setting. During spinning, molten polymer is extruded through small orifices in a spinneret to form filaments. As these filaments leave the spinneret, they need to be rapidly cooled to solidify. The spinning air duct, with its annularly distributed air nozzles, generates an airflow surrounding the filaments. This airflow facilitates rapid cooling and prevents fiber entanglement, ensuring fiber quality and production efficiency.

[0003] After a period of use, the interior of a spinning air duct becomes contaminated with dust and low-molecular-weight substances, necessitating cleaning. Current cleaning methods involve manually disassembling the air box, removing the air duct, replacing it with a clean one, reinstalling the air box, and conducting a sealing test. The removed air duct is then ultrasonically cleaned, most of the water is blown away with compressed air, and finally dried in an oven until it is completely dry. This cleaning method requires disassembling and reassembling the air box and air duct, is cumbersome, time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an online cleaning device for spinning ducts with high cleaning efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An online cleaning device for spinning ducts, comprising:

[0007] A sealed chamber is slidably disposed in the front-to-back direction and at least partially slidable in the up-down direction. The lower part of the sealed chamber is open and is used to cover the top of the spinning air duct to seal the top of the spinning air duct.

[0008] A sealing plate, which can be slidably disposed in the front-back and up-down directions, is used to cover the underside of the spinning air duct to seal the underside of the spinning air duct;

[0009] A nozzle assembly, movably disposed within the sealed chamber, is used to inject high-pressure airflow into the spinning air duct;

[0010] An air supply mechanism is located outside the sealed chamber and communicates with the nozzle assembly.

[0011] In some embodiments, the sealed chamber includes a main body that can be slidably disposed in a front-to-back direction and a barrier that can be slidably disposed in a vertical direction at the lower part of the main body. The lower part of the main body is open, and the barrier has an open-loop annular structure. The sealed chamber has a first state and a second state. When the sealed chamber is in the first state, the barrier is fitted over the outside of the lower part of the main body, and the lower end of the barrier is not lower than the lower end of the main body. When the sealed chamber is in the second state, a portion of the barrier extends below the main body, and the inner side of the barrier portion is in contact with the outer side of the main body.

[0012] In some embodiments, the nozzle assembly is slidably disposed within the sealed chamber in a left-right direction.

[0013] In some embodiments, a first guide rail extending in a left-right direction and a slider slidably disposed on the first guide rail along the length extension direction of the first guide rail are fixedly disposed inside the sealed chamber, and the nozzle assembly is disposed on the slider.

[0014] In some embodiments, the nozzle assembly is also slidably disposed within the sealed chamber in a vertical direction, and / or the nozzle assembly is also rotatably disposed within the sealed chamber.

[0015] In some embodiments, the nozzle assembly includes a nozzle body and an intake shaft, the intake shaft extending in a vertical direction and having an intake channel, the nozzle body being fixedly disposed at the lower part of the intake shaft, the intake shaft being slidably disposed on the slider, and / or the intake shaft being rotatably disposed on the slider about its own axis.

[0016] In some embodiments, the intake shaft is a spline shaft, and the cleaning device further includes a drive member fixedly disposed within the slider, the drive member being sleeved outside the spline shaft and cooperating with the spline shaft.

[0017] In some embodiments, the air supply mechanism includes an air source device and an air booster, wherein the outlet of the air source device is connected to the inlet of the air booster via a pipeline, and the outlet of the air booster is connected to the intake passage of the intake shaft via a pipeline.

[0018] In some embodiments, the cleaning device further includes a bracket, a second guide rail fixedly mounted on the bracket and extending in a vertical direction, and a roller that can slide and rotate along the length extension direction of the second guide rail, the roller being rotatably mounted on the sealing plate.

[0019] In some embodiments, the cleaning device further includes an air handling chamber for collecting exhaust gas, wherein the rear portion of the sealed chamber has a tapered section with a gradually decreasing cross-sectional area from front to rear, and the rear end of the tapered section is provided with an air outlet for exhaust gas to exit the sealed chamber, the air outlet being connected to the air handling chamber.

[0020] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: When cleaning the spinning duct online cleaning device of this utility model, a sealing chamber is installed above the spinning duct to seal the top of the spinning duct, and a sealing plate is placed below the spinning duct to seal the bottom of the spinning duct, thus forming a sealed environment.

Detailed Implementation

[0034] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] like Figures 1-5 As shown, the online cleaning device for spinning air ducts of this utility model includes a frame 1, a sealed chamber 2, a sealing plate 31, a nozzle assembly 4, and an air supply mechanism.

[0037] The lower part of the sealing chamber 2 is open, and it is used to cover the top of the spinning air duct to seal the top of the spinning air duct. The sealing chamber 2 is slidable in the front-back direction and at least partially slidable in the vertical direction. By sliding the sealing chamber 2 back and forth, the sealing chamber 2 is moved to a position corresponding to the spinning air duct. By sliding all or part of the sealing chamber 2 downward, the lower end of the sealing chamber 2 abuts against the upper end surface of the component on which the spinning air duct is mounted, and the upper end of the spinning air duct is covered inside the sealing chamber 2.

[0038] Specifically, such as Figures 6 to 11 As shown, the sealed chamber 2 includes a main body 21 and a barrier 22 disposed at the lower part of the main body 21. The lower part of the main body 21 is open, and the barrier 22 has an annular structure that is open both vertically and horizontally. The main body 21 can be slidably disposed in the front-to-back direction, and the barrier 22 can be slidably disposed at the lower part of the main body 21 in the vertical direction.

[0039] In this embodiment, the frame 1 is slidably mounted in the front-to-back direction, and the main chamber 21 is fixedly mounted on the frame 1, so that when the frame 1 slides in the front-to-back direction, the sealed chamber 2 slides synchronously in the front-to-back direction. The cleaning device also includes a first drive mechanism (not shown in the figure), which drives the frame 1 to slide in the front-to-back direction.

[0040] The sealed chamber 2 has a first state and a second state. When the sealed chamber 2 is in the first state, the enclosure 22 is fitted over the lower part of the main chamber 21, and the lower end of the enclosure 22 is not lower than the lower end of the main chamber 21. This prevents interference between the sealed chamber 2 and other components from affecting its normal sliding when the frame 1 drives the sealed chamber 2 to slide in the front-to-back direction. Figure 8 and Figure 9 As shown. When the sealed chamber 2 is in the second state, the enclosure 22 extends below the main chamber 21, and the lower end of the enclosure 22 abuts against the upper surface of the component housing the spinning air duct. At this time, there is an overlap area between the upper part of the enclosure 22 and the lower part of the main chamber 21, and in the overlap area, the inner side of the enclosure 22 fits against the outer side of the main chamber 21 to ensure the sealing performance of the sealed chamber 2. Figure 10 and Figure 11 As shown.

[0041] like Figures 6 to 11 As shown, the sealed chamber 2 also includes a second drive mechanism 23, which drives the enclosure 22 to slide up and down relative to the main chamber 21. The second drive mechanism 23 can be respectively arranged on opposite sides along the length of the sealed chamber 2, so that the enclosure 22 is subjected to uniform force and the phenomenon of sliding and jamming due to uneven force on the enclosure 22 can be avoided. The second drive mechanism can be a cylinder, with the cylinder body fixedly mounted on the main chamber 21 and the piston rod fixedly mounted on the enclosure 22.

[0042] The sealing plate 31 is used to block and seal the area below the spinning air duct. The sealing plate 31 is slidable in the front-back and up-down directions. By sliding the sealing plate 31 back and forth, it moves to a position corresponding to the spinning air duct. By sliding the sealing plate 31 upward, its upper end face abuts against the lower end face of the component housing the spinning air duct, blocking the lower outlet of the spinning air duct.

[0043] In this embodiment, the sealing plate 31 is slidably mounted on the frame 1 in the up-down direction. When the frame 1 slides in the front-back direction, it drives the sealing plate 31 to slide synchronously in the front-back direction.

[0044] Specifically, such as Figures 1-5 As shown, a second guide rail 12 extending vertically is fixedly mounted on the bracket 11, and a roller 32 is rotatably mounted on the sealing plate 31. The roller 32 can slide and rotate along the length of the second guide rail 12. When the sealing plate 31 slides up and down, the roller 32 guides the sliding of the sealing plate 31 through its cooperation with the second guide rail 12. Moreover, when the roller 32 slides relative to the second guide rail 12, the two make rolling contact, which reduces frictional resistance and thus reduces the driving force.

[0045] The cleaning device also includes a third drive mechanism 33, which drives the sealing plate 31 to slide up and down relative to the bracket 11. The third drive mechanism 33 may be a cylinder, with the cylinder body fixedly mounted on the bracket 11 and the piston rod fixedly mounted on the sealing plate 31.

[0046] The nozzle assembly 4 is used to spray high-pressure airflow into the spinning air duct. The nozzle assembly 4 is located in the sealed chamber 2. When the upper part of the spinning air duct is sealed by the sealed chamber 2 and the lower part of the spinning air duct is sealed by the sealing plate 31, the nozzle assembly 4 is in a sealed space. This can prevent the high-pressure airflow sprayed by the nozzle assembly 4 from leaking out and reducing the airflow pressure, thereby affecting the cleaning effect.

[0047] The nozzle assembly 4 is movably installed inside the sealed chamber 2. By adjusting the position of the nozzle assembly 4, the high-pressure airflow ejected by the nozzle assembly 4 can fully act on the spinning air duct that needs to be cleaned, thereby improving the cleaning effect.

[0048] Specifically, the nozzle assembly 4 is slidably disposed within the sealed chamber 2 in a left-right direction. The cleaning device also includes a fourth drive mechanism for driving the nozzle assembly 4 to slide in a left-right direction. The fourth drive mechanism includes a first guide rail 51 extending in a left-right direction and a slider 52 slidably disposed on the first guide rail 51 along the length of the first guide rail 51. The first guide rail 51 is fixedly disposed on the main chamber 11, and the nozzle assembly 4 is disposed on the slider 52. When the slider 52 slides along the first guide rail 51, it drives the nozzle assembly 4 to slide synchronously.

[0049] The nozzle assembly 4 can also be slidably disposed within the sealed chamber 2 in the vertical direction, and / or the nozzle assembly 4 can also be rotatably disposed within the sealed chamber 2.

[0050] Specifically, such as Figure 12 As shown, the nozzle assembly 4 includes a nozzle body 41 and an air intake shaft 42. The air intake shaft 42 extends in the vertical direction and has an air intake channel. The nozzle body 41 is fixedly disposed at the lower part of the air intake shaft 42. The air intake shaft 42 is slidably disposed on the ground block 52, and / or the air intake shaft 42 is rotatably disposed on the ground block 52 around its own axis.

[0051] In this embodiment, the nozzle assembly 4 can slide vertically while rotating. This allows for both vertical sliding and rotation of the nozzle assembly 4 with only one fifth drive mechanism, simplifying the structure of the cleaning device, making it easy to control, and saving costs. Specifically, the air intake shaft 42 is a splined shaft. The cleaning device also includes a drive component 53 fixedly mounted within the slider 52. The drive component 53 is sleeved on the outside of the splined shaft and engages with it. When the splined shaft is driven to rotate by the fifth drive mechanism, the nozzle assembly 4 rotates synchronously. During rotation, the splined shaft slides vertically relative to the drive component 53 through the engagement between the splined shaft and the drive component 53, causing the nozzle body 41 to slide vertically vertically. The fifth drive mechanism can be a motor 54.

[0052] The air supply mechanism is located outside the sealed chamber 2 and is connected to the nozzle assembly 4 to provide compressed air to the nozzle assembly 4.

[0053] The air supply mechanism includes an air source device (not shown in the figure) and an air booster 6. The outlet of the air source device is connected to the inlet of the air booster 6 via a pipeline (not shown in the figure), and the outlet of the air booster 6 is connected to the air intake channel on the air intake shaft 42 via a pipeline (not shown in the figure). The compressed air output from the air source device is pressurized by the air booster 6; in this embodiment, the pressure is increased by at least two times. This causes the outlet of the nozzle assembly 4 to form a high-pressure, high-speed jet that acts inside the spinning air tube, which can improve the peeling force on dust and adhering substances, resulting in a better cleaning effect.

[0054] The cleaning device also includes an air handling unit 7 for collecting exhaust gas. The rear of the main body 21 has a constriction section 211 with a cross-sectional area that gradually decreases from front to back. The rear end of the constriction section 211 is provided with an air outlet for the exhaust gas in the sealed chamber 2 to flow out of the sealed chamber 2. The air outlet is connected to the air handling unit 7, so that the exhaust gas in the sealed chamber 2 flows into the air handling unit 7.

[0055] An exhaust port is provided on the air handling unit 7, and a filter screen is installed at the exhaust port. After the exhaust gas in the air handling unit 7 is filtered, the clean air is discharged to the outside of the air handling unit 7 through the exhaust port, while impurities in the exhaust gas are retained in the air handling unit 7.

[0056] The bottom of the air handling unit 7 is equipped with a door that can be opened and closed to facilitate the regular cleaning of impurities and other debris from the air handling unit 7.

[0057] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
