Circular knitting machines can efficiently weave yarn into cylindrical or disc-shaped fabrics to meet the needs of textile factories for cloth production. During operation, circular knitting machines will produce impurities such as cotton dust and cotton wool, which float and diffuse throughout the textile workshop. While polluting the air quality of the workshop, there are also serious safety hazards. Therefore, appropriate dust removal methods must be adopted to ensure the normal operation of circular knitting machines. Common dust removal methods for circular knitting machines include mechanical dust removal, airflow dust removal, and combined dust removal.

[0003] In the prior art, when the circular knitting machine is dusted by airflow dust removal, a yarn-feeding cotton wool cleaning device is added to the lower end of the knitting part, so that when the circular knitting machine is running, the yarn-feeding cotton wool cleaning device continuously performs a cleaning operation of blowing away the cotton wool through a high-pressure airflow, so as to prevent foreign objects such as dust and cotton wool from being mixed in the cloth and being woven together. However, while the dust removal of the yarn-feeding cotton wool cleaning device maintains the normal operation of the circular knitting machine, it also blows the cotton wool disorderly into the air of the textile workshop, aggravating the deterioration of the workshop air quality. Therefore, it is urgent to find a method for effectively removing the dust and cotton wool generated during the working process of the circular knitting machine, so as to improve the workshop air quality while cleaning the dust and cotton wool of the circular knitting machine, and effectively eliminate safety hazards.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the present application clearer, the specific embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present application, rather than to limit the present application.

[0041] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In a more common existing implementation, when the circular knitting machine is dusted by airflow dust removal, a yarn-feed cotton wool cleaning device is added to the lower end of the knitting part, so that when the circular knitting machine is running, the yarn-feed cotton wool cleaning device uses high-pressure airflow to continuously perform dust removal and cotton wool cleaning operations to prevent foreign objects such as dust and cotton wool from being mixed in the cloth and being woven together. However, the dust removal area of ​​the yarn-feed cotton wool cleaning device is limited, and it cannot efficiently clean the cotton wool generated by the various components of the circular knitting machine, and the dust removal effect is poor and the dust removal efficiency is low. Moreover, the cotton wool will be blown to the top of the textile workshop by the high-pressure airflow, causing air pollution to the textile workshop, which seriously affects the production environment quality of the textile workshop.

[0043] In order to solve the above problems, the embodiment of the present application provides a dust removal device for a circular knitting machine, by setting a wire harness dust suction unit under the wire harness of the circular knitting machine and setting a plurality of needle disk dust suction components around the inner side of the needle disk, so as to efficiently absorb the cotton wool at the wire harness and the needle disk where the cotton wool is mainly produced in the circular knitting machine, optimize the dust removal effect and improve the dust removal efficiency, and the cotton wool will not be blown to the top of the textile workshop, avoiding air pollution in the textile workshop, and ensuring the production environment quality of the textile workshop. By setting airflow induction units on both sides of the wire harness, the cotton wool generated by the wire harness during operation and thrown to the surroundings can be induced to fall into the wire harness dust suction unit along the constraint area formed by the airflow curtain, so as to prevent the cotton wool from floating out of the circular knitting machine and further optimize the air quality of the textile workshop.

[0044] In one embodiment, Figure 1-4 They are respectively an internal structure diagram, a top view, an exploded isometric view and an isometric view of the dust removal device for a circular knitting machine provided in an embodiment of the present application. Figure 1-4 As shown, the circular knitting machine dust removal device 20 includes: a vacuum cleaner main unit 21, a negative pressure suction main pipe 22, a cable tie dust suction unit 25 and a needle plate dust suction unit. The vacuum cleaner main unit 21 is connected to the exhaust port of the negative pressure suction main pipe 22, and the air inlet of the negative pressure suction main pipe 22 is connected to the cable tie dust suction unit 25 and the needle plate dust suction unit; the cable tie dust suction unit 25 is arranged below the cable tie 11 of the circular knitting machine 10, and the cable tie dust suction unit 25 is used to absorb the cotton wool of the cable tie 11 and transport the absorbed cotton wool to the vacuum cleaner main unit 21 through the negative pressure suction main pipe 22; the needle plate dust suction unit includes a plurality of needle plate dust suction components 26, and the plurality of needle plate dust suction components 26 are arranged around the inner side of the needle plate 12 of the circular knitting machine 10, and the needle plate dust suction components 26 are used to absorb the cotton wool of the needle plate 12 and transport the absorbed cotton wool to the vacuum cleaner main unit 21 through the negative pressure suction main pipe 22.

[0045] For example, when the vacuum cleaner main unit 21 is running, the negative pressure air suction pipe 22 and the cable binder dust suction unit 25 generate an air flow from the dust suction port of the cable binder dust suction unit 25 to the exhaust port of the negative pressure air suction pipe 22. Under the action of the air flow, the cable binder dust suction unit 25 absorbs the cotton wool of the cable binder 11 and drops it into the dust suction port and transports the absorbed cotton wool to the inside of the vacuum cleaner main unit 21 along the negative pressure air suction pipe 22, thereby achieving efficient absorption of the cotton wool generated at the cable binder 11. Moreover, the cotton wool falls from top to bottom into the dust suction port of the cable binder dust suction unit 25, and is also in a sealed space during the process of being transported to the vacuum cleaner main unit 21. The cotton wool will not float above the circular knitting machine 10, thereby ensuring the air quality of the textile workshop. At the same time, the negative pressure suction pipe 22 and the needle disk dust suction assembly 26 generate an air flow from the dust suction port of the needle disk dust suction assembly 26 to the exhaust port of the negative pressure suction pipe 22. Under the action of the air flow, the needle disk dust suction assembly 26 absorbs the cotton wool in the corresponding area of ​​the needle disk 12 and drops it into the dust suction port and transports the absorbed cotton wool to the inside of the vacuum cleaner main unit 21 along the negative pressure suction pipe 22. Since the needle disk dust suction assembly 26 is provided in multiple areas of the needle disk 12, efficient absorption of the cotton wool generated in all directions of the needle disk 12 is achieved. Moreover, the cotton wool is absorbed from the outside to the inside into the dust suction port of the needle disk dust suction assembly 26, and is also in a sealed space during the process of being transported to the vacuum cleaner main unit 21. The cotton wool will not float to the outside of the circular knitting machine 10, ensuring the air quality of the textile workshop.

[0046] It can be understood that when the vacuum cleaner host 21 is running, the cable harness dust suction unit 25 and the needle disk dust suction unit work simultaneously to absorb the cotton wool at the cable harness 11 and the needle disk 12 respectively, thereby achieving synchronous cleaning of the cotton wool at the cable harness 11 and the needle disk 12, and effectively improving the dust removal efficiency of the circular knitting machine 10.

[0047] Furthermore, Figure 5 1 is a diagram showing the internal structure of the dust removal device for a circular knitting machine provided in an embodiment of the present application. Figure 5As shown, the cable tie dust collection unit 25 includes an annular dust collection disc 251 and a first air suction pipe 252. The annular dust collection disc 251 is arranged below the cable tie 11. The dust inlet of the annular dust collection disc 251 faces the cable tie 11, and the dust outlet of the annular dust collection disc 251 is connected to the air inlet of the first air suction pipe 252. The exhaust port of the first air suction pipe 252 is connected to the air inlet of the negative pressure air suction main pipe 22; wherein, the dust inlet of the annular dust collection disc 251 is larger than the corresponding dust outlet. Exemplarily, the dust inlet of the annular dust disc 251 is the dust inlet of the cable binder dust unit 25. Since the dust inlet of the annular dust disc 251 is located below the cable binder 11, when the vacuum cleaner main unit 21 is running, the air flow formed between the negative pressure air suction pipe 22 and the first air suction pipe 252 will cause an air flow from top to bottom at the dust inlet of the annular dust disc 251. Under the action of the air flow at the dust inlet of the annular dust disc 251, the cotton wool at the cable binder 11 will fall into the corresponding annular dust disc 251 below, and be transported to the vacuum cleaner main unit 21 along the air flow in the first air suction pipe 252 and the negative pressure air suction pipe 22, thereby achieving efficient adsorption of the cotton wool at the cable binder 11 without generating flying cotton wool, thereby ensuring the air quality of the textile workshop.

[0048] refer to Figure 5 The dust inlet area of ​​the annular dust collecting disc 251 is larger than the cross-sectional area of ​​the cable tie 11, that is, the dust inlet of the annular dust collecting disc 251 can completely cover the entire cable tie 11, so that the cable tie 11 and the surrounding cotton wool can fall into the annular dust collecting disc 251, thereby improving the cleaning ability of the cable tie 11 by the cable tie dust collecting unit 25. The height of the annular dust collecting disc 251 is adjustable, and the height of the annular dust collecting disc 251 can be adjusted according to actual needs so that the cotton wool of the cable tie 11 can fall into the annular dust collecting disc 251 better.

[0049] In one embodiment, reference Figure 1-4 The circular knitting machine dust removal device 20 also includes an air suction pressure equalizing collection pipe 24, the air inlet of the air suction pressure equalizing collection pipe 24 is connected to the cable tie dust collection unit 25 and the needle plate dust collection unit, and the exhaust port of the air suction pressure equalizing collection pipe 24 is connected to the air inlet of the negative pressure suction main pipe 22. Exemplarily, the air suction pressure equalizing collection pipe 24 and the negative pressure suction main pipe 22 are arranged above the circular knitting machine 10, and the vacuum cleaner host 21 is arranged on one side of the circular knitting machine 10. Since the air inlet of the suction pressure equalizing collection pipe 24 is connected to the cable tie dust suction unit 25 and each needle disk dust suction component 26 of the needle disk dust suction unit, and the exhaust port of the suction pressure equalizing collection pipe 24 is connected to the air inlet of the negative pressure suction main pipe 22, the suction pressure equalizing collection pipe 24 can balance the air flow formed between the negative pressure suction main pipe 22 and the cable tie dust suction unit 25 and each needle disk dust suction component 26, balance the adsorption capacity of the cable tie dust suction unit 25 and each needle disk dust suction component 26 for cotton wool, avoid the phenomenon of uneven dust removal effect in various areas of the circular knitting machine 10, and optimize the dust removal effect.

[0050] In one embodiment, reference Figure 5 The circular knitting machine dust removal device 20 also includes an airflow induction unit 27, which is arranged on both sides of the cable tie 11. The airflow induction unit 27 is used to form an airflow curtain on both sides of the cable tie 11 to induce the cotton fluff generated by the cable tie 11 during operation to fall into the cable tie dust collection unit 25 along the constraint area formed by the airflow curtain. Exemplarily, two blowers can be arranged above both sides of the cable tie 11, and the airflow from top to bottom is blown out by the two blowers. The airflow blown out by the two blowers forms an airflow curtain on both sides of the cable tie 11. The airflow curtain on both sides of the cable tie 11 can form a constraint area surrounding the cable tie 11. The airflow curtain can isolate the cotton fluff generated by the cable tie 11 during operation from being thrown around in the constraint area, so as to prevent the cotton fluff from floating out of the circular knitting machine 10 and ensure the air quality of the textile workshop. The cotton wool inside the air curtain falls into the annular dust collecting plate 251 under the action of the air flow at the annular dust collecting plate 251 , thereby achieving efficient adsorption of the cotton wool at the cable tie 11 .

[0051] In this embodiment, Figure 6 The embodiment of this application provides Figure 5 A magnified view of part A. Figure 6As shown, the airflow induction unit 27 includes a positive pressure air blowing pipe 23, an inner ring air curtain pipe 272, an outer ring air curtain pipe 271, an inner ring airflow induction pipe 276, an outer ring airflow induction pipe 274, an inner ring air outlet ring 277 and an outer ring air outlet ring 279. The air inlet of the positive pressure air blowing pipe 23 is connected to the vacuum cleaner main unit 21, and the air outlet of the positive pressure air blowing pipe 23 is connected to the air inlet of the inner ring air curtain pipe 272 and the air inlet of the outer ring air curtain pipe 271; the air outlet of the inner ring air curtain pipe 272 is connected to the air inlet of the inner ring air flow induction pipe 276, and the air outlet of the inner ring air flow induction pipe 276 is connected to the inner ring air outlet ring 277; the air outlet of the outer ring air curtain pipe 271 is connected to the air inlet of the outer ring air flow induction pipe 274, and the air outlet of the outer ring air flow induction pipe 274 is connected to the outer ring air outlet ring 279; wherein, the inner ring air outlet ring 277 and the outer ring air outlet ring 279 are respectively located above the two sides of the cable tie 11. Exemplarily, when the vacuum cleaner main unit 21 is running, an air flow from the air inlet to the air outlet is generated in the positive pressure air blowing pipe 23, and the air flow is evenly divided into two air flows by the inner ring air curtain pipe 272 and the outer ring air curtain pipe 271. The air flow in the inner ring air curtain main pipe 272 passes through the inner ring air flow induction pipe 276 and is uniformly and continuously ejected by the inner ring air outlet ring 277, forming the inner ring air curtain 32 inside the cable tie 11. The air flow in the outer ring air curtain main pipe 271 passes through the outer ring air flow induction pipe 274 and is uniformly and continuously ejected by the outer ring air outlet ring 279, forming the outer ring air curtain 31 outside the cable tie 11. Below the outer ring air curtain 31 and the inner ring air curtain 32 is the edge of the annular dust suction plate 251. Under the isolation effect of the outer ring air curtain 31 and the inner ring air curtain 32, the cotton wool at the cable tie 11 inside the outer ring air curtain 31 and the inner ring air curtain 32 can fall accurately into the annular dust suction plate 251, preventing the cotton wool from floating out of the circular knitting machine 10 while achieving efficient adsorption of the cotton wool at the cable tie 11.

[0052] For further reference, Figure 6The airflow induction unit 27 further includes an inner ring nozzle 278 and an outer ring nozzle 275. The inner ring nozzle 278 is connected to the exhaust port of the inner ring airflow induction pipe 276, and the outer ring nozzle 275 is connected to the exhaust port of the outer ring airflow induction pipe 274. The inner ring nozzle 278 and the outer ring nozzle 275 are located directly above the cable tie 11. Exemplarily, the airflow in the inner ring air curtain main pipe 272 passes through the inner ring airflow induction pipe 276 and is compressed and ejected by the inner ring nozzle 278 to form a compressed airflow 33 from top to bottom. The airflow in the outer ring air curtain main pipe 271 passes through the inner ring airflow induction pipe 276 and is compressed and ejected by the outer ring nozzle 275 to form a compressed airflow 33 from top to bottom. Since the inner ring nozzle 278 and the outer ring nozzle 275 are arranged directly above the cable tie 11, the compressed air flow 33 sprayed by the inner ring nozzle 278 and the outer ring nozzle 275 can pass through the cable tie 11 to blow off the cotton wool adhering to the cable tie 11, thereby preventing the cotton wool from remaining on the cable tie 11, and effectively improving the dust removal effect of the cable tie 11. Due to the existence of the outer ring air curtain 31 and the inner ring air curtain 32, the blown-off cotton wool will not float out of the circular knitting machine 10 but will accurately fall into the annular dust suction disc 251 below the cable tie 11, thereby achieving efficient adsorption of the cotton wool at the cable tie 11.

[0053] refer to Figure 6 The airflow induction unit 27 also includes a dust collector air blowing pipe 273, an outer ring air blowing pipe 280 and an inner ring air blowing pipe 281. The air inlet of the dust collector air blowing pipe 273 is connected to the exhaust port of the positive pressure air blowing pipe 23, and the exhaust port of the dust collector air blowing pipe 273 is connected to the air inlets of the outer ring air blowing pipe 280 and the inner ring air blowing pipe 281. The lower sides of the outer ring air blowing pipe 280 and the inner ring air blowing pipe 281 are provided with a plurality of evenly distributed openings, which are opened toward the cable tie dust collection unit 25. The outer ring air blowing pipe 280 and the inner ring air blowing pipe 281 are respectively located below the two sides of the cable tie 11. Exemplarily, the air flow generated in the positive pressure air blowing pipe 23 flowing from the air inlet to the exhaust port is divided and enters the dust collector air blowing pipe 273. The air flow in the dust collector air blowing pipe 273 is evenly divided into two air flows by the outer ring air blowing pipe 280 and the inner ring air blowing pipe 281. The air flow in the outer ring air blowing pipe 280 is ejected from multiple evenly distributed openings on the lower side of the outer ring air blowing pipe 280 to form an outer ring air flow 34 from top to bottom, and the air flow in the inner ring air blowing pipe 281 is ejected from multiple evenly distributed openings on the lower side of the inner ring air blowing pipe 281 to form an inner ring air flow 35 from top to bottom. Under the action of the inner ring air flow 35 and the outer ring air flow 34, all the cotton wool flushed out of the cable tie 11 by the compressed air flow 33 falls into the annular dust collecting plate 251, which in disguise enhances the adsorption capacity of the annular dust collecting plate 251 on the cotton wool at the cable tie 11, reduces or even avoids the cotton wool residue, and effectively improves the dust removal effect of the cable tie 11.

[0054] In one embodiment, Figure 7 The embodiment of this application provides Figure 5 A magnified view of part B. Figure 5 and Figure 7 As shown, the needle tray dust suction assembly 26 includes a dust suction head 264 and a second air suction pipe 261. The dust inlet of the dust suction head 264 is arranged close to the inner side of the needle tray 12. The dust discharge port of the dust suction head 264 is connected to the air inlet of the second air suction pipe 261. The exhaust port of the second air suction pipe 261 is connected to the air inlet of the negative pressure air suction main pipe 22. Exemplarily, the dust suction port of the needle tray dust suction assembly 26 is the dust inlet of the dust suction head 264. The dust suction head 264 is arranged on the inner side of the needle tray 12, and the dust inlet of the dust suction head 264 is close to and faces the inner side of the needle tray 12. When the vacuum cleaner main unit 21 is running, the air flow formed between the negative pressure suction pipe 22 and the second suction pipe 261 will cause the dust inlet of the dust suction head 264 to generate an air flow from the outside of the needle tray 12 to the inside of the needle tray 12. Under the action of the air flow at the dust inlet of the dust suction head 264, the cotton wool adhered to the needle tray 12 will be absorbed into the dust suction head 264 and transported to the vacuum cleaner main unit 21 along the air flow in the second suction pipe 261 and the negative pressure suction pipe 22, thereby achieving efficient absorption of the cotton wool at the corresponding position of the needle tray 12 without generating flying cotton wool, thereby ensuring the air quality of the textile workshop.

[0055] In this embodiment, reference Figure 2 The air suction pressure equalizing collection tube 24 is an annular tube, and the second dust suction tube can be evenly arranged around the air suction pressure equalizing collection tube 24 and connected to the air suction pressure equalizing collection tube 24 to balance the air flow in each second dust suction tube, and then balance the adsorption capacity of each dust suction head 264, avoid the uneven dust removal effect of the needle disk 12, and optimize the dust removal effect.

[0056] For further reference, Figure 5 The needle tray dust collection assembly 26 also includes a universal positioning tube 262, the air inlet of the universal positioning tube 262 is connected to the dust outlet of the dust collection head 264, and the exhaust port of the universal positioning tube 262 is connected to the air inlet of the second suction pipe 261. The universal positioning tube 262 is used to adjust the position of the correspondingly connected dust collection head 264. Exemplarily, the universal positioning tube 262 can adjust the height, angle and horizontal position of the dust collection head 264. When the position of the dust collection head 264 deviates from the needle tray 12 or when it is desired to adjust the area of ​​the needle tray 12 that the dust collection head 264 is aligned with, the height, angle and horizontal position of the dust collection head 264 can be adjusted through the universal positioning tube 262, so that the dust collection head 264 connected to the universal positioning tube 262 can be close to and face the inner side of a certain area of ​​the needle tray 12, thereby ensuring the adsorption capacity of the needle tray dust collection assembly 26. When the vacuum cleaner main unit 21 is running, the vacuum head 264 absorbs the cotton wool in the corresponding area of ​​the needle plate 12 , and the cotton wool absorbed by the vacuum head 264 is transported to the vacuum cleaner main unit 21 along the universal positioning tube 262 , the second suction pipe 261 and the negative pressure suction main pipe 22 .

[0057] It should be noted that the vacuum head 264 is detachably connected to the universal positioning tube 262. When the vacuum head 264 is deformed, damaged, or needs to be cleaned, the vacuum head 264 can be removed from the universal positioning tube 262 for replacement or cleaning.

[0058] refer to Figure 5 , the needle plate dust collection assembly 26 also includes an automatic valve 263, and the circular knitting machine dust removal device 20 includes a control unit. The automatic valve 263 is arranged on the second air suction pipe 261; the control unit is electrically connected to the automatic valve 263, and the control unit is used to control the switch of the automatic valve 263. Exemplarily, when the automatic valve 263 is opened, an air flow from the dust collection head 264 to the vacuum cleaner main unit 21 is formed between the negative pressure air suction main pipe 22, the second air suction pipe 261 and the universal positioning pipe 262. Under the action of the air flow, the dust collection head 264 can absorb the cotton wool in the corresponding area of ​​the needle plate 12. The control unit can control the automatic valves 263 on each second air suction pipe 261 to open and close at the same time. When all the automatic valves 263 are opened at the same time, each dust collection head 264 can absorb the cotton wool in each area of ​​the needle plate 12, thereby achieving comprehensive cleaning of the needle plate 12 and improving the dust removal efficiency of the needle plate 12. Alternatively, the second air intake pipes 261 are divided into multiple groups, and the automatic valves 263 on each group of second air intake pipes 261 are controlled to open at different times to absorb the cotton wool in each area of ​​the needle plate 12 in batches, thereby achieving comprehensive cleaning of the needle plate 12 and reducing the air volume requirements for the vacuum cleaner main unit 21, thereby saving the installation cost of the vacuum cleaner main unit 21.

[0059] In one embodiment, a plurality of needle tray dust collection assemblies 26 in the needle tray dust collection unit are fixedly installed at various areas inside the needle tray 12 , and the needle tray dust collection assemblies 26 are used to absorb and clean the cotton wool in the corresponding areas of the needle tray 12 .

[0060] In another embodiment, the needle disk dust suction unit further includes a rotating assembly, which connects a plurality of needle disk dust suction assemblies 26, and is used to drive the plurality of needle disk dust suction assemblies 26 to rotate along the inner side of the needle disk 12. Exemplarily, the rotating assembly may adopt a rotary joint, which is used to connect the air suction pressure equalizing collection tube 24 and each second dust suction tube so that the air flow between the air suction pressure equalizing collection tube 24 and each second dust suction tube can flow through the rotary joint. A rotating bearing is arranged inside the rotary joint, and when the rotating bearing rotates, it can drive the plurality of second dust suction tubes to rotate so that the plurality of dust suction heads 264 rotate along the inner side of the needle disk 12, and the plurality of dust suction heads 264 absorb the cotton wool in the needle disk 12 during the rotation process, so as to achieve full coverage of the needle disk 12, thereby greatly improving the dust removal ability of the needle disk dust suction unit. Among them, the rotating bearing can drive each second dust suction tube to rotate forward or reverse. Or, refer to Figure 2The air intake pressure equalizing collection pipe 24 is an annular pipe, and the air inlet of the negative pressure air intake main pipe 22 is connected to the middle of the air intake pressure equalizing collection pipe 24. The negative pressure air intake main pipe 22 and the air intake pressure equalizing collection pipe 24 are connected by a rotating joint, so that the air intake pressure equalizing collection pipe 24 can rotate relative to the negative pressure air intake main pipe 22 under the action of the rotating joint. A rotating bearing is arranged inside the rotating joint, and when the rotating bearing rotates, it can drive the air intake pressure equalizing collection pipe 24 to rotate. When the air intake pressure equalizing collection pipe 24 rotates, it can drive the correspondingly connected multiple second dust suction pipes to rotate, so that the multiple dust suction heads 264 rotate along the inner side of the needle disk 12. During the rotation process, the multiple dust suction heads 264 absorb the cotton wool in the needle disk 12 to achieve full coverage of the needle disk 12, which greatly improves the dust removal capacity of the needle disk dust suction unit. Among them, the rotating bearing can be driven to rotate by a motor or a cylinder.

[0061] It should be noted that when the air intake pressure equalizing collection pipe 24 can rotate, if the first air intake pipe 252 is also connected to the air intake pressure equalizing collection pipe 24, the first air intake pipe 252 and the annular dust collecting plate 251 will be driven by the air intake pressure equalizing collection pipe 24 to rotate, thereby offsetting the cable tie 11, causing the cable tie dust collecting unit 25 to fail. When the air intake pressure equalizing collection pipe 24 is connected to the negative pressure air intake main pipe 22 through a rotating joint, the first air intake pipe 252 can be connected to the negative pressure air intake main pipe 22. Since the negative pressure air intake main pipe 22 will not rotate when the air intake pressure equalizing collection pipe 24 rotates, the first air intake pipe 252 and the annular dust collecting plate 251 will not rotate either, thereby ensuring the normal operation of the cable tie dust collecting unit 25. Alternatively, the first intake pipe 252 is connected to the middle of the negative pressure intake pipe 22 through a rotating joint. Specifically, the air inlet of the negative pressure intake pipe 22 is connected to the middle position above the intake pressure equalizing collection pipe 24 through a rotating joint, and the exhaust port of the first intake pipe 252 is connected to the middle position below the intake pressure equalizing collection pipe 24 through another rotating joint. When the intake pressure equalizing collection pipe 24 rotates, the negative pressure intake pipe 22 and the first intake pipe 252 remain stationary.

[0062] As described above, the circular knitting machine dust removal device 20 provided in the embodiment of the present application is provided by arranging a wire tie device dust collection unit 25 under the wire tie device 11 of the circular knitting machine 10 and surrounding a plurality of needle disk dust collection assemblies 26 on the inner side of the needle disk 12, connecting the wire tie device dust collection unit 25 and the needle disk dust collection assembly 26 to the air inlet of the negative pressure suction pipe 22, and connecting the exhaust port of the negative pressure suction pipe 22 to the vacuum cleaner main unit 21, so that when the vacuum cleaner main unit 21 is running, the cotton wool attached to the wire tie device 11 can be absorbed into the wire tie device dust collection unit 25 through the air flow, and the cotton wool absorbed by the wire tie device dust collection unit 25 can be transferred to the vacuum cleaner main unit 21 through the negative pressure suction pipe 22. The cotton wool attached to each area of ​​the needle disk 12 is transported to the vacuum cleaner host 21, and the cotton wool attached to each area of ​​the needle disk 12 is absorbed into the needle disk dust collection assembly 26 set in the corresponding area through the air flow, and the cotton wool absorbed by the wire harness dust collection unit 25 is transmitted to the vacuum cleaner host 21 through the negative pressure suction main pipe 22, so as to achieve efficient adsorption of the cotton wool at the wire harness 11 and the needle disk 12 of the main cotton wool in the circular knitting machine 10, and prevent the cotton wool from flying into the air of the textile workshop, and solve the problem that the cotton wool generated by each component of the circular knitting machine 10 cannot be efficiently cleaned in the prior art and the cotton wool will aggravate the air pollution in the workshop, and optimize the dust removal effect while improving the air quality in the workshop. By setting airflow induction units 27 on both sides of the wire harness 11, the cotton wool generated by the wire harness 11 during operation and thrown to the surroundings is induced to fall into the wire harness dust collection unit 25 along the constraint area formed by the airflow curtain, so as to prevent the cotton wool from floating out of the circular knitting machine 10 and ensure the air quality of the textile workshop.
