Description

Technical Field

[0001] The present invention relates to the technical field of spinning equipment cleaning, and in particular to an online cleaning device and method for spinning equipment. Background Art

[0002] During the spinning process, molten polymer is extruded through the small holes in the spinneret, forming fine filaments. As these filaments exit the spinnerets, annularly distributed airflow is generated by the blower through the air outlets, surrounding the filaments. This airflow facilitates rapid cooling and prevents fiber entanglement, ensuring fiber quality and production efficiency. After the spun filaments are extruded from the spinneret, they are bundled and oiled by the nozzles on the oil rack assembly to enhance the cohesiveness, smoothness, and antistatic properties of the filaments, facilitating subsequent processing. During the spinning process, the high temperature and sublimation of oligomers in the polymer melt produce a white powder, which adheres to the spinneret. Furthermore, the curing of the silicone oil sprayed on the spinneret before spinning causes a lot of dirt to form on the spinneret. Dust and low-molecular-weight particles also adhere to the quiet area above the blower and the oil rack / nozzle. Therefore, the spinneret, blower, and oil rack / nozzle should be cleaned after a period of operation.

[0003] In the prior art, the commonly used cleaning methods for spinnerets, blowers and oil racks / nozzles are as follows:

[0004] Spinneret cleaning: After manually spraying special atomized silicone oil on the spinneret surface, scraping it with a spatula. This cleaning method is time-consuming and labor-intensive, and the cleaning quality varies greatly. In addition, scraping with a spatula can easily damage the spinneret surface.

[0005] Air duct cleaning: Manually inserting the waste yarn into the air duct and pulling it back and forth to wipe off the dust. This method only transfers the dust but does not collect it, and instead increases the difficulty of cleaning other parts. Alternatively, the air duct can be manually disassembled and then cleaned using ultrasonic waves. This offline cleaning method has the following main problems: (1) Disassembly and assembly are cumbersome, (2) After replacement, alignment and sealing performance testing must be performed. (3) Physical property testing of the product must be performed after spinning. (4) Ultrasonic cleaning also requires the addition of chemical reagents.

[0006] Oil rack / oil nozzle cleaning: Generally, the oil rack / oil nozzle is wetted by spraying water manually, and then wiped to remove dirt.

[0007] Although some devices in the prior art are capable of online cleaning of the spinneret, they are unable to simultaneously achieve online cleaning of the blower and the oil rack / nozzle. That is, in the prior art, the cleaning of the spinneret, blower and oil rack / nozzle is performed independently and generally cannot be cleaned online, which is time-consuming, labor-intensive and inefficient. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide an online cleaning device for spinning equipment which can simultaneously perform online cleaning on a spinneret, a blower cylinder and an oil rack / oil nozzle.

[0009] In order to achieve the above object, the technical solution adopted by the present invention is:

[0010] An online cleaning device for spinning equipment, comprising:

[0011] The spinneret cleaning mechanism comprises a working bucket slidably arranged in a front-to-rear direction and a first nozzle assembly for spraying a cleaning medium onto the spinneret, the first nozzle assembly being slidably arranged in the working bucket in a left-to-right direction, the working bucket comprising a box body with an open top and a barrier assembly arranged around the top periphery of the box body, the barrier assembly being slidably arranged on the box body up and down, the working bucket having a first state and a second state, when the working bucket is in the first state, the barrier assembly slides downward to a low position, and when the working bucket is in the second state, the barrier assembly slides upward to a high position, and a cutting portion for cutting the wire is further formed on the upper portion of the front portion of the barrier assembly;

[0018] The seat body is fixedly connected to the bottom of the hopper assembly, and the air inlet channel and the discharge channel are both arranged on the seat body. The discharge channel is connected to the particle channel, and there is a spacing area between the inlet of the discharge channel and the outlet of the particle channel. The air intake of the air inlet channel forms a negative pressure in the spacing area.

[0019] In some embodiments, the first blanking plate is provided with a first blanking port passing through its upper and lower end surfaces, the second blanking plate is provided with a second blanking port passing through its upper and lower end surfaces, and the dividing plate is provided with a dividing port passing through its upper and lower end surfaces. The first blanking port, the dividing port, and the second blanking port form the blanking channel. The position of the first blanking port is staggered with the position of the second blanking port. The rotation of the dividing plate can make the dividing port correspond to the position of the first blanking port or the second blanking port.

[0020] In some embodiments, the spinneret cleaning mechanism further comprises a sticky plate cake detachably mounted on the first nozzle assembly, the first nozzle assembly having a channel for the flow of a cleaning medium; the first nozzle assembly has an operating state and a non-operating state, when the first nozzle assembly is in the operating state, the sticky plate cake is detached from the first nozzle assembly, and the outlet of the channel is unobstructed; when the first nozzle assembly is in the non-operating state, the sticky plate cake is mounted on the first nozzle assembly and blocks the outlet of the channel;

[0021] In some embodiments, when the adhesive plate cake is disposed on the first nozzle assembly, the adhesive plate cake can also be rotatably disposed relative to the first nozzle assembly.

[0022] In some embodiments, the air duct cleaning mechanism includes a sealed cabin for covering the top of the air duct to seal the top of the air duct and a sealing plate for covering the bottom of the air duct to seal the bottom of the air duct, the sealed cabin is arranged at the bottom of the working bucket, the sealed cabin is at least partially slidable up and down, the sealing plate is slidable up and down at the lower part of the sealed cabin, and the second nozzle assembly is slidable in the left and right directions in the sealed cabin.

[0023] In some embodiments, the sealed cabin includes a main cabin body fixedly arranged at the bottom of the working bucket and an enclosure that can be slidably arranged at the lower part of the main cabin body in the up and down directions. The lower part of the main cabin body is open, and the enclosure is an annular structure open at the top and bottom. The sealed cabin has a first state and a second state. When the sealed cabin is in the first state, the enclosure is mounted on the outside of the lower part of the main cabin body, and the lower end of the enclosure is not lower than the lower end of the main cabin body; when the sealed cabin is in the second state, the enclosure part extends to the bottom of the main cabin body, and the inner side of the enclosure part is in contact with the outer side of the main cabin body.

[0024] In some embodiments, the cleaning media sprayed by the first nozzle assembly, the second nozzle assembly, and the third nozzle assembly all include compressed gas, and the online cleaning device also includes a main air supply mechanism for supplying air to the first nozzle assembly, the second nozzle assembly, and the third nozzle assembly.

[0025] In some embodiments, the online cleaning device also includes a guide rail extending in the left-right direction, and the spinneret cleaning mechanism, the air duct cleaning mechanism and the oil rack / nozzle cleaning mechanism can all be slidably arranged along the length extension direction of the guide rail. The total air supply mechanism includes a gas channel arranged in the guide rail and extending along its length direction and a total air intake pipeline connected to the gas channel through a pipe joint, and the total air intake pipeline is respectively connected to the spinneret cleaning mechanism, the air duct cleaning mechanism and the oil rack / nozzle cleaning mechanism.

[0026] The present invention also provides an online cleaning method for spinning equipment, based on any one of the above-mentioned online cleaning devices for spinning equipment, the cleaning method comprising:

[0027] (1) moving the working bucket forward to a position below the spinneret, and allowing the working bucket to encompass the spinneret;

[0028] (2) after the silk thread is cut by the cutting portion, the upper end surface of the enclosure assembly is placed against the end surface of the spinning equipment;

[0029] (3) spraying a cleaning medium onto the spinneret through the first nozzle assembly to clean the spinneret; spraying a cleaning medium onto the air cylinder through the second nozzle assembly to clean the air cylinder; spraying a cleaning medium onto the oil rack / nozzle through the third nozzle assembly to clean the oil rack / nozzle;

[0030] (4) After cleaning is completed, the working bucket is moved backward to the initial position, and the working bucket is placed in the first state after the wire is cut by the cutting part.

[0031] In some embodiments, before the second nozzle assembly sprays the cleaning medium into the air cylinder, the top and bottom of the air cylinder are sealed to form a sealed space, and the second nozzle assembly is located in the sealed space.

[0032] In some embodiments, after the cleaning medium is sprayed onto the spinneret through the first nozzle assembly, the spinneret is wiped by clamping the sticky plate cake through a clamping assembly, and the clamping assembly is disposed on the first nozzle assembly.

[0033] Due to the application of the above technical solution, the present invention has the following advantages over the prior art: When the spinneret is cleaned, a sealed space is formed between the working bucket and the spinning equipment. The first nozzle assembly and the spinneret are both located within this sealed space, allowing the working bucket to collect waste yarn ejected from the spinneret during the cleaning process. This prevents the waste yarn from being scattered around the blower, oil rack / nozzle, and other parts under the influence of the high-speed airflow ejected by the first nozzle assembly. It also prevents the cleaning medium ejected by the first nozzle assembly and dirt and impurities dropped from the spinneret from being scattered around the blower, oil rack / nozzle, and other parts. In this way, the cleaning of the spinneret, blower, and oil rack / nozzle components does not affect each other, allowing the spinneret, blower, and oil rack / nozzle to be cleaned online simultaneously, resulting in high efficiency. Furthermore, during the cleaning process, the forward and backward movement of the working bucket can simultaneously adjust the forward and backward positions of the first, second, and third nozzle assemblies, simplifying the overall structure and operational control process, thereby reducing the time of the entire cleaning process and improving efficiency.

[0080] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0081] In the description of the present invention and the description of the patent of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the patented product is typically placed when in use. These terms are intended only to facilitate the description of the patent and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the patent of the present invention. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0082] like Figures 1 to 4 As shown, the online cleaning device for spinning equipment of the present invention comprises a frame 11, a spinneret cleaning mechanism, a blower cylinder cleaning mechanism and an oil rack / nozzle cleaning mechanism.

[0083] The spinneret cleaning mechanism is used to clean the spinneret, and includes a working bucket 21, a first nozzle assembly 3, a sticky plate cake 41, a sticky plate cake feeding mechanism and a cleaning medium supply mechanism.

[0084] When cleaning the spinneret, a sealed space is formed between the working bucket 21 and the spinning equipment. The first nozzle assembly 3 and the spinneret are both located within this sealed space, allowing the working bucket 21 to collect waste fibers ejected from the spinneret during the cleaning process. This prevents the waste fibers from being scattered and difficult to clean due to the high-speed airflow ejected by the first nozzle assembly 3. It also prevents the cleaning medium ejected by the first nozzle assembly 3 and dirt and impurities that fall from the spinneret from being scattered to other parts of the spinning equipment, thereby affecting the simultaneous cleaning of other parts. This also eliminates the need for subsequent cleaning of other parts of the spinning equipment, saving time and effort.

[0085] The working bucket 21 is mounted on the frame 11 so as to slide forward and backward. The working bucket 21 has a storage space within which the first nozzle assembly 3 is mounted so as to slide left and right. A first drive mechanism 12 is also mounted on the frame 11 to drive the working bucket 21 forward and backward. A second drive mechanism 22 is also mounted within the working bucket 11 to drive the first nozzle assembly 3 left and right. Both the first drive mechanism 12 and the second drive mechanism 22 can be linear motors or slide cylinders.

[0086] like Figures 5 to 7 As shown, the working bucket 21 includes a box body 211 with an open top and a barrier assembly arranged around the top periphery of the box body 211. The barrier assembly is slidably arranged on the box body 211. The working bucket 21 has a first state and a second state.

[0087] When the working bucket 21 slides in the forward and backward directions toward or away from the spinneret, the working bucket 21 is in the first state. At this time, the enclosure assembly slides downward to a low position, and there is a gap between the upper end face of the enclosure assembly and the end face of the spinning equipment, so that the working bucket 21 can move forward and backward without hindrance.

[0088] When the working bucket 21 moves forward to a position below the spinneret and is able to completely accommodate the spinneret within its accommodating space, the working bucket 21 is in the second state. At this time, the enclosure assembly slides upward to a high position, and the upper end surface of the enclosure assembly abuts the end surface of the spinning equipment, thereby forming a sealed space between the working bucket 21 and the spinning equipment. At this time, the first nozzle assembly 3 can spray a cleaning medium to clean the spinneret.

[0089] In this embodiment, the rear portion of the housing 211 is higher than the left and right sides and the front portion of the housing 211, and the upper end surface of the rear portion of the housing 211 is located above the end surface of the spinning equipment. The enclosure assembly includes side baffles 212 and a front baffle 213. The side baffles 212 are respectively slidably disposed on the upper portions of the left and right sides of the housing 211, and the front baffle 213 is slidably disposed on the upper portion of the front portion of the housing 211. When the working bucket 21 is in the second state, the rear portion of the housing 211 abuts the rear end surface of the spinning equipment to ensure the sealing of the sealed space formed between the working bucket 21 and the spinning equipment. The abutment of the rear portion of the housing 211 against the rear end surface of the spinning equipment by the rear portion of the housing 211 also limits the sliding movement of the working bucket 21.

[0090] The side baffles 212 and the front baffle 213 on the left and right sides are independently provided. A cutting portion 2131 is formed on the upper portion of the front baffle 213. Figure 7 and Figure 8 As shown. During cleaning, the working bucket 21 is moved forward into position, and the front baffle 213 is moved back and forth up and down, allowing the cutting portion 2131 to cut the yarn ejected from the spinneret, causing the cut waste yarn to fall into the wind tube located below the spinneret for collection. After cleaning is completed, the working bucket 21 is moved backward into position, and the front baffle 213 is moved back and forth up and down, allowing the cutting portion 2131 to cut the yarn ejected from the spinneret, causing the cut waste yarn to fall into the working bucket 21 for collection.

[0091] The cutting portion 2131 is formed by a tip provided at the upper end of the front baffle 213. Figure 7 and Figure 8 shown.

[0092] The working bucket 21 further comprises a third driving mechanism 214 for driving the side baffles 212 to slide up and down and a fourth driving mechanism 215 for driving the front baffle 213 to slide up and down. Both the third driving mechanism 214 and the fourth driving mechanism 215 can be cylinders.

[0093] The working bucket 21 is also provided with a guide member 216. A plurality of guide members 216 are provided at intervals along the left and right directions of the working bucket 21 corresponding to the spinneret. The guide members 216 are located outside the working bucket 21. The guide members 216 are used to guide the waste silk so that the waste silk can fall smoothly into the air duct below the spinneret after being cut and collected.

[0094] In this embodiment, the guide member 216 is fixedly arranged on the outer side of the front of the box body 211. The guide member 216 has a conical structure with a larger upper part and a smaller lower part. The front of the cone is open to facilitate the entry of waste silk into the cone.

[0095] like Figure 6As shown, the bottom of the box 211 is provided with a discharge port 2111. The bottom of the box 211 is formed by multiple inclined surfaces arranged from top to bottom, and the discharge port 2111 converges at the lowest end of the multiple inclined surfaces. In this way, when waste silk, the cleaning medium sprayed by the first nozzle assembly, and dirt and impurities falling from the spinneret fall into the working bucket 21, they will automatically flow out of the discharge port 2111 along the various inclined surfaces to the outside of the working bucket 21 for collection and processing.

[0096] like Figures 5 to 7 As shown, a processing box 23 is fixedly installed below the working bucket 21, and the discharge port 2111 of the box body 211 is connected to the processing box 23, so that the waste silk, cleaning medium, dirt and impurities dropped from the spinneret in the working bucket 21 all flow into the processing box 23.

[0097] The processing box 23 is provided with an exhaust port, and a filter is provided at the exhaust port. After the exhaust gas in the processing box 23 is filtered, the clean air is discharged to the outside of the processing box 23 through the exhaust port, and the impurities in the exhaust gas are retained in the processing box 23.

[0098] The bottom of the processing box 23 is provided with a door panel that can be opened and closed, so as to facilitate regular cleaning of impurities and the like in the processing box 23 .

[0099] Based on the problem that silicone oil used as a cleaning medium in the prior art cannot achieve a good cleaning effect and requires scraping by a spatula, in this embodiment, the cleaning media used to clean the spinneret include particles, silicone oil and compressed gas.

[0100] like Figures 9 to 14 As shown, the first nozzle assembly 3 includes a robotic arm 31 and a nozzle body 32. The nozzle body 32 is mounted on the robotic arm 31, which has multiple degrees of freedom. The first nozzle assembly 3 is moved as a whole, and the position of the nozzle body 32 is adjusted by the movement of the robotic arm 31 itself, so that the nozzle body 32 is moved to the spinneret position to perform the spinneret cleaning operation.

[0101] like Figure 13 and Figure 14 As shown, the nozzle body 32 includes a housing 321 and a nozzle 322. The housing 321 is provided at the end of the robotic arm 31 and has a receiving cavity. The nozzle 322 is provided on the housing 321, with most of the nozzle located in the receiving cavity of the housing 321. The nozzle 322 sprays the atomized liquid silicone oil and the metered granular medium onto the spinneret surface.

[0102] Specifically, such as Figure 13As shown, a channel for the atomized liquid silicone oil and the metered granular medium to flow out is provided in the nozzle 322, and the channel includes a contraction section and an expansion section arranged in sequence. The contraction section is arranged in the accommodating cavity of the shell 321, and the expansion section partially extends to the outside of the shell 321. The contraction section and the expansion section are both conical structures, and the small end of the contraction section is connected with the small end of the expansion section in sequence to form a throat. After the cleaning medium enters the channel in the nozzle 322, it first enters the contraction section. After the contraction section contracts, the flow rate of the atomized liquid silicone oil and the metered granular medium in the channel increases. After the expansion section expands, the flow rate further increases, forming a high-speed jet, which is ejected onto the spinneret surface, thereby utilizing the impact force generated by the high-speed jet to continuously and forcefully flush the spinneret surface, peel off and flush the attachments on the spinneret surface, and achieve the effect of cleaning the plate.

[0103] In this embodiment, the expansion section is relatively long along the length of the channel, being longer than the contraction section. Furthermore, the expansion section is flat. This ensures that the atomized liquid silicone oil and metered granular medium are sprayed onto the spinneret surface at a specific angle and direction, thereby improving the cleaning effect. In this embodiment, the expansion section has a square cross-section.

[0104] The nozzle body 32 further includes an input pipe 323 , which is disposed on the nozzle 322 and communicates with the contraction section. The input pipe 323 is used to communicate with a cleaning medium supply mechanism so that the cleaning medium flows into the channel of the nozzle 322 .

[0105] After the first nozzle assembly 3 sprays the cleaning medium onto the spinneret, the dirt on the spinneret surface is wiped off by the sticky plate cake 41, which can make the cleaning process more complete and the cleaning effect better. The sticky plate cake 41 is detachably arranged on the nozzle body 32. Specifically, the nozzle body 32 has a working state and a non-working state. When the nozzle body 32 is in the working state, the sticky plate cake 41 is separated from the nozzle body 32, and the outlet of the channel of the nozzle head 322 is unblocked. At this time, the cleaning medium can be sprayed onto the spinneret surface through the nozzle body 32, as shown in FIG. Figure 10 and Figure 11 When the nozzle body 32 is in a non-working state, the sticky plate cake 41 is set on the nozzle body 32 and blocks the outlet of the nozzle 322 channel. At this time, the sticky plate cake 41 is placed on the spinneret surface to wipe the dirt on the spinneret surface. At the same time, the sticky plate cake 41 blocks the dirt and prevents it from entering the nozzle 322 channel. Figure 9 shown.

[0106] In this embodiment, the sticky plate 41 is set on the nozzle body 32, and the nozzle body 32 and the sticky plate 41 can be driven to move and adjust their positions by the same set of mechanisms, which makes the overall structure simple, saves costs, and makes full use of each mechanism.

[0107] The sticky cake feeding mechanism is used to automatically clamp the sticky cake 41 onto the nozzle assembly. The sticky cake feeding mechanism includes a clamping assembly, a storage barrel 51 and a pushing device. The clamping assembly is set on the nozzle assembly, and the storage barrel 51 and the pushing device are both set on the working bucket 21 and are located outside the accommodating space of the working bucket 21. Figures 16 to 21 shown.

[0108] The box body 211 is provided with an opening 2112 for opening the storage space. The size of the opening 2112 is not less than the size of the sticky plate cake 41. A material taking platform is provided at the opening 2112. The material taking platform is located in the storage space of the working bucket 21. The material taking platform is used to temporarily store the sticky plate cake 41 to be picked up.

[0109] like Figure 18 As shown, the retrieving platform includes a lower support platform 217 disposed below the opening 2112 and an upper support platform 218 disposed above the opening 2112. The upper support platform 218 includes an upper support portion and an upper stop extending downwardly therefrom, while the lower support platform 217 includes a lower support portion and a lower stop extending upward therefrom. The upper and lower support portions respectively support opposite sides of the sticky plate cake 41. The upper and lower stops both abut against the end surfaces of the sticky plate cake 41, thereby preventing the sticky plate cake 41 from falling off the retrieving platform. In this embodiment, both the upper support platform 218 and the lower support platform 217 are L-shaped.

[0110] The clamping assembly is directly or indirectly disposed on the nozzle body 322 . The clamping assembly is used to clamp the sticky plate cake 41 from the material taking platform and place the sticky plate cake 41 on the nozzle body 32 .

[0111] like Figures 10 to 14 As shown, the clamping assembly includes two clamping members 42 , at least one of which is slidably disposed relative to the nozzle body 32 .

[0112] Each clamping member 42 includes a supporting portion 421 and a clamping portion 422 disposed on the supporting portion 421. The supporting portion 421 is used to support the adhesive plate cake 41. The clamping portions 422 are arranged on two clamping members 42, each of which is positioned opposite to the other, forming a clamping space for the adhesive plate cake 41. When the clamping assembly is used to clamp the adhesive plate cake 41, the adhesive plate cake 41 is placed on the two supporting portions 421. At least one clamping member 421 slides relative to the nozzle body 32, causing the clamping portion 422 to move toward the clamping space. This causes the two clamping portions 422 to abut against opposite sides of the adhesive plate cake 41, thereby clamping the adhesive plate cake 41 in the clamping assembly. When at least one clamping portion 422 slides away from the clamping space, the clamping assembly releases the adhesive plate cake 41, allowing the adhesive plate cake 41 to be removed from the nozzle body 32.

[0113] In this embodiment, the bearing portion 421 is a flat plate structure, and the clamping portion 422 is arranged on the outer periphery of the bearing portion 421. The clamping portion 422 is adapted to the sticky plate 41. For example, if the cross section of the sticky plate 41 is circular, the clamping portion 422 is an arc-shaped plate.

[0114] The supporting portion 421 is provided with an opening, which passes through both end surfaces of the supporting portion 421 in the thickness direction, and the nozzle 322 is disposed in the opening.

[0115] In this embodiment, one of the two clamping members 42 is relatively fixed, and the other clamping member 42 slides in a direction away from the fixed clamping member 42 .

[0116] The clamping assembly further includes a fifth driving mechanism, which is used to drive a clamping member 42 to slide. Figure 14 As shown, the fifth driving mechanism includes a cylinder 43, wherein the slidable clamping member 42 further includes a connecting portion 423 provided at the bottom of the bearing portion 421, and the connecting portion 423 is connected to the piston rod of the cylinder 43. When the piston rod is extended or retracted, the clamping member 42 connected thereto can be driven to slide.

[0117] Of course, both clamping members 42 can also be slid relative to the nozzle body 322, for example, the two clamping members 42 can simultaneously slide toward each other, thereby approaching each other to clamp the sticky plate 41. The two clamping members 42 can also simultaneously slide away from each other, thereby releasing the sticky plate 41 and separating it from the nozzle body 322.

[0118] The fifth driving mechanism includes a clamping cylinder, which includes a cylinder body and two clamping jaws that can slide toward and away from each other at the same time. Each clamping member 42 also includes a connecting portion 423 arranged at the bottom of the bearing portion 421, and the two connecting portions 423 are respectively connected to the two clamping jaws in a one-to-one correspondence.

[0119] When the clamping assembly is used to clamp the sticky plate cake 41 at the retrieving platform, the clamping assembly is moved to the retrieving platform, and the positions of the two clamping parts 422 of the clamping assembly are offset from the positions of the lower support platform 217 and the upper support platform 218. The fifth drive mechanism is activated, driving the clamping member 42 to move until the two clamping parts 422 respectively abut against opposite sides of the sticky plate cake 41, thereby transferring the sticky plate cake 41 from the retrieving platform to the clamping assembly.

[0120] The sticky plate cake 41 can also be rotatably arranged on the clamping assembly around its own axis. When the sticky plate cake 41 is used to wipe the dirt on the spinneret surface, the sticky plate cake 41 can be rotated to achieve a better cleaning effect.

[0121] The sticky plate cake feeding mechanism further includes a sixth driving mechanism, which is used to drive the sticky plate cake 41 to rotate around its own axis.

[0122] like Figure 15 As shown, the sixth drive mechanism includes a first gear 441 rotatably disposed within the nozzle body 322, a second gear 442 rotatably disposed within the nozzle body 322, a rotary disk 443 fixedly connected to the second gear 442, and a motor 444 for rotating the first gear 441. The first gear 441 meshes with the second gear 442. The rotary disk 443 is rotatably disposed outside the nozzle body 322. One clamping member 42 is fixedly disposed on the rotary disk 443, and the other clamping member 42 is slidably disposed on the rotary disk 443.

[0123] When the motor 444 is started, it drives the first gear 441 to rotate. Through the engagement of the first gear 441 and the second gear 442, the second gear 442 rotates following the first gear 441, thereby driving the turntable 443 to rotate, and the clamping assembly set on the turntable 443 rotates, thereby driving the sticky plate cake 41 to rotate.

[0124] An opening is also provided on the turntable 443 at a position corresponding to the opening of the bearing portion 421 . The opening passes through both end surfaces of the turntable 443 in the thickness direction. The nozzle 322 extends through the opening into the opening on the clamping member 42 .

[0125] like Figure 20 and Figure 21 As shown, the storage barrel 51 has a cavity extending along its length for storing the sticky plate cakes 41. The sticky plate cakes 41 are sequentially placed in the cavity along the length of the storage barrel 51. The cavity of the storage barrel 51 is open at both ends along its length, forming an inlet and an outlet, respectively, for feeding and discharging materials. One end of the outlet of the storage barrel 51 is fixedly mounted on the working bucket 21, and the outlet of the storage barrel 51 corresponds to the position of the opening 2112 on the working bucket 21.

[0126] The pushing device is used to push the sticky plate cakes 41 in the storage barrel 51 to the material taking platform in sequence for the clamping assembly to clamp them.

[0127] like Figure 20 and Figure 21 As shown, the pushing device includes a push plate 521, which is slidably disposed in the cavity of the storage barrel 51 along the length of the storage barrel 51. When the push plate 521 slides toward the outlet of the storage barrel 51, it pushes the sticky plate cakes 41 in the storage barrel 51, thereby pushing out the sticky plate cakes 41 in the storage barrel 51 one by one and pushing them onto the material removal platform.

[0128] The pusher device further includes a slidably mounted driving member 522 and a power mechanism 523 for driving the driving member 522 to slide. The power mechanism 523 is mounted on the working bucket 21, and the driving member 522 cooperates with the push plate 521. When the power mechanism 523 drives the driving member 522 to slide, the driving member 522 and the push plate 521 cooperate to cause the push plate 521 to slide synchronously.

[0129] In this embodiment, the driving member 522 is disposed outside the storage barrel 51 , and the driving member 522 and the push plate 521 cooperate with each other through magnetic force. Specifically, the driving member 522 is a magnetic ring, and the magnetic ring is sleeved outside the storage barrel 51 .

[0130] The power mechanism 523 includes a guide rail 5231 extending along the length of the storage barrel 51 and a slider 5232 slidably mounted on the guide rail 5231 along the length of the guide rail 5231. The guide rail 5231 is fixed to the working bucket 21. A base 524 is fixed to the slider 5232. The base 524 is annular and fits over the exterior of the storage barrel. The inner wall of the base 524 is provided with a slot. The driver 522 is mounted in the slot and secured relative to the base 524. The power mechanism 523 can be implemented as a linear motor or a slide cylinder.

[0131] When the power mechanism 523 is started, the slider 5232 slides along the guide rail 5231 , driving the driving member 522 to slide synchronously. Due to the magnetic force between the driving member 522 and the push plate 521 , the push plate 521 can be driven to slide synchronously.

[0132] like Figure 16 and Figure 19 As shown, the pushing device also includes a sensor 525 for monitoring the position of the push plate 521 within the storage barrel 51. The sensor 525 is disposed on the power mechanism 523 and is located near the working bucket 21. When the push plate 521 moves within the storage barrel 51 into the sensing range of the sensor 525, the sensor 525 sends a sensing signal, prompting the storage barrel 51 to be filled with the sticky plate cakes 41.

[0133] The push plate 521 is detachably mounted within the storage barrel 51. A hand-operated operating portion 5211 is provided on the end surface of the push plate 521 facing the outside of the storage barrel 51. When the storage barrel 51 needs to be filled with sticky plate cakes 41, the operating portion 5211 is grasped to detach the push plate 521 from the storage barrel 51. The inlet of the storage barrel 51 is then opened, and the storage barrel 51 can be filled with sticky plate cakes 41.

[0134] The frame 11 is provided with an openable and closable door panel 111 at the position corresponding to the material storage barrel 51. When it is necessary to fill the sticky plate cakes 41 into the material storage barrel 51, the door panel 111 can be opened.

[0135] The cleaning medium supply mechanism is used to supply the cleaning medium to the first nozzle assembly 3. Figure 22 As shown, the cleaning medium supply mechanism includes a silicone oil supply mechanism, a particle supply mechanism, a first air supply mechanism and a main pipeline 6.

[0136] The silicone oil supply mechanism is used to transport the liquid silicone oil to the main pipeline 6 after atomization, and the silicone oil supply mechanism is arranged on the frame 11. Specifically, Figure 22 As shown, the silicone oil supply mechanism includes an oil storage tank 71, an oil pump 72, an oil temporary storage tank 73 and a nozzle 74. The oil storage tank 71, the oil pump 72, the oil temporary storage tank 73 and the nozzle 74 are connected in sequence through an oil inlet pipeline (not shown in the figure).

[0137] The oil storage tank 71 is used to store liquid silicone oil.

[0138] Oil pump 72 is used to pump the liquid silicone oil from oil storage tank 71 into temporary oil storage tank 73. The silicone oil supply mechanism also includes a motor 75, which is connected to and drives oil pump 72. By controlling the speed of motor 75, the pressure of the liquid silicone oil entering temporary oil storage tank 73 can be increased, forming high-pressure silicone oil.

[0139] The oil temporary storage tank 73 is used to temporarily store high-pressure silicone oil.

[0140] The nozzle 74 is used to atomize the high-pressure silicone oil and spray it into the main pipeline 6. The nozzle 74 is formed with an oil inlet 741 and an oil outlet. The oil inlet 741 is connected to the oil storage tank 73 through the oil inlet pipeline, and the oil outlet is connected to the main pipeline 6.

[0141] The silicone oil supply mechanism also includes a control valve, which controls the oil output from nozzle 74. The control valve also closes the silicone oil supply mechanism's oil inlet, preventing the atomized silicone oil from being ejected from the oil outlet of nozzle 74. The control valve can be integrated with nozzle 74, such as a solenoid valve nozzle. Alternatively, the control valve can be provided separately from nozzle 74, located on the oil inlet line between oil storage tank 73 and nozzle 74.

[0142] The nozzle 74 is further formed with an oil return port 742 , which is connected to the oil storage tank 71 via an oil return pipeline (not shown in the figure).

[0143] The silicone oil supply mechanism also includes flowmeters 76, which are installed on the oil inlet and return lines between the oil reservoir 71 and the oil pump 72. The flowmeter 76 on the oil inlet line measures the flow rate of silicone oil entering the nozzle 74, while the flowmeter on the return line measures the flow rate of silicone oil returning to the oil reservoir 71. The difference between the two values ​​can be used to measure the flow rate of silicone oil used to clean the spinneret.

[0144] The particle supply mechanism and the first air supply mechanism are used to transport the granular medium into the main pipeline 6 under the push of compressed gas. The particle supply mechanism has an air inlet channel 841 for compressed gas to enter the particle supply mechanism, and a discharge channel for particles and compressed gas to flow out of the particle supply mechanism. The first air supply mechanism is connected to the air inlet channel 841, and the discharge channel is connected to the main pipeline 6.

[0145] Specifically, the particle supply mechanism is provided on the frame 11 and includes a hopper assembly, a discharge assembly and a base.

[0146] like Figures 23 to 28 As shown, the hopper assembly has a storage cavity for storing granular medium. In this embodiment, the hopper assembly includes an upper hopper 811 located at the upper part and a lower hopper 812 located at the lower part. A granular channel 8321 is provided in the lower hopper 812 for the granular medium to flow out of the hopper assembly.

[0147] The material discharge assembly is provided on the hopper assembly and divides the storage chamber into an isolated upper cavity 8111 and a lower cavity 8121. In this embodiment, the material discharge assembly is provided between the upper hopper 811 and the lower hopper 812, the upper cavity 8111 is formed on the upper hopper 811, and the lower cavity 8121 is formed on the lower hopper 812.

[0148] The discharge assembly is located above the granular channel 8321 and contains a discharge channel for the granular medium. The discharge assembly has two states: a discharge state and a non-discharge state. When the discharge assembly is in the discharge state, the discharge channel is unobstructed, allowing the granular medium to flow from the upper chamber 8111 through the discharge channel into the lower chamber 8121 and out of the hopper assembly through the granular channel 8321. When the discharge assembly is in the non-discharge state, the discharge channel is blocked, and the granular medium is stored in the upper chamber 8111.

[0149] like Figure 26 and Figure 28 As shown, in this embodiment, the blanking assembly includes a first blanking plate 821, a second blanking plate 822 and a feed tray 823. The second blanking plate 822 is arranged below the first blanking plate 821, and the feed tray 823 is arranged between the first blanking plate 821 and the second blanking plate 822, and can be rotatably arranged relative to the first blanking plate 821 and the second blanking plate 822. In this embodiment, the second blanking plate 822 is provided with a groove that is concave downward from the upper end surface, and the feed tray 823 can be rotatably arranged in the groove. The upper cavity 8111 is formed above the first blanking plate 821, and the lower cavity 8121 is formed below the second blanking plate 822. When the feed tray 823 rotates, the blanking channel is unblocked. When the feed tray 823 does not rotate, the blanking channel is blocked.

[0150] Specifically, such as Figure 24 、 Figure 26 and Figure 28As shown, the first blanking plate 821 is provided with a first blanking port 8211 which passes through the upper and lower end surfaces thereof, the second blanking plate 822 is provided with a second blanking port 8221 which passes through the upper and lower end surfaces thereof, and the dividing plate 823 is provided with a dividing port 8231 which passes through the upper and lower end surfaces thereof. The first blanking port 8211, the dividing port 8231 and the second blanking port 8221 are arranged in sequence from top to bottom to form a blanking channel. The position of the first blanking port 8211 is staggered with the position of the second blanking port 8221. The sizes of the first blanking port 8211 and the second blanking port 8221 are both larger than the size of the dividing port 8231. The rotation of the dividing plate 823 can make the dividing port 8231 correspond to the position of the first blanking port 8211 or the second blanking port 8221.

[0151] When the unloading assembly is in the unloading state, the distributing plate 823 first rotates until the distributing opening 8231 corresponds to the position of the first unloading opening 8211, and the granular medium in the upper cavity 8111 flows from the first unloading opening 8211 into the distributing opening 8231. At this time, the position of the distributing opening 8231 is offset from the position of the second unloading opening 8221. When the distributing plate 823 continues to rotate until the position of the distributing opening 8231 corresponds to the position of the second unloading opening 8221, the granular medium in the distributing opening 8231 flows through the second unloading opening 8221 into the lower cavity 8121.

[0152] When the unloading component is in a non-unloading state, the distribution plate 823 does not rotate, and the distribution plate 823 can only correspond to the position of one of the first unloading port 8211 and the second unloading port 8221 at most. In this way, the unloading channel is always in a blocked state and unloading cannot be achieved.

[0153] This type of material discharge method of the material discharge component can prevent the granular medium from flowing out of the material discharge channel when material discharge is not required, thereby improving the controllability of material discharge.

[0154] Along the circumferential direction of the rotation of the distribution plate 823, there is at least one first discharge port 8211 and a second discharge port 8221, and a plurality of distribution ports 8231 are provided. In this embodiment, there are two first discharge ports 8211 and two second discharge ports 8221, and a plurality of distribution ports 8231 are evenly spaced along the circumferential direction of the rotation of the distribution plate 823. Such arrangement enables that when one feed port 8231 corresponds to the position of the first feed port 8211 to realize feed discharge from the first feed port 8211 to the feed port 8231, when the feed port 8231 rotates to the position corresponding to the second feed port 8221 to realize feed discharge from the feed port 8231 to the second feed port 8221, another feed port 8231 can be rotated again to the position corresponding to the first feed port 8211 to realize feed discharge from the first feed port 8211 to the feed port 8231, and such a cycle can make the feed discharge process continuous and improve the feeding efficiency.

[0155] The unloading assembly also includes a seventh drive mechanism 824, which drives the distribution tray 823 to rotate. In this embodiment, the seventh drive mechanism 824 has a rotatable output shaft 8241, and the distribution tray 823 is fixedly connected to the output shaft 8241. When the seventh drive mechanism 824 is activated, the output shaft 8241 rotates, driving the distribution tray 823 to rotate synchronously. In this embodiment, the seventh drive mechanism 824 includes a drive motor.

[0156] By controlling the speed of the driving motor, the purpose of measuring the amount of granular medium discharged can be achieved.

[0157] The first discharge plate 821 has a tapered structure at one end facing the upper cavity 8111, with a larger top and a smaller bottom. The first discharge opening 8211 is located near the smaller end of the tapered structure. This allows the granular medium in the upper cavity 8111 to more easily fall into the first discharge opening 8211 under the guidance of the tapered structure and its own gravity.

[0158] The particle supply mechanism further includes a material guide 83 disposed within the lower cavity 8121. The material guide 83 is located below the feed assembly, and a particle channel 8321 is formed on the material guide 83. The material guide 83 is used to guide the granular medium that falls into the lower cavity 8121 so that the granular medium flows out of the hopper assembly through the particle channel 8321.

[0159] Specifically, such as Figure 4 、 Figure 6 and Figure 8 As shown, the material guide 83 includes a disk 831 at the top and a first column 832 disposed below the disk 831. The disk 831 has a tapered structure that is larger at the top and smaller at the bottom. The first column 832 is sequentially connected to the small end of the disk 831. A particle channel 8321 is formed in the first column 832. In this embodiment, the particle channel 8321 is the center hole of the first column 832.

[0160] After the granular medium falls from the second discharge port 8221, it falls onto the disc 831. The conical structure of the disc 831 can play a good guiding role, making it easier for the granular medium to fall into the granular channel 8321 under the action of its own gravity.

[0161] like Figure 26 As shown, the base 84 is fixedly connected to the hopper assembly. In this embodiment, the base 84 is fixedly connected to the lower portion of the lower hopper 812. The air inlet channel 841 and the discharge channel are both formed on the base 84. A spacing area is provided between the inlet of the discharge channel and the outlet of the particle channel 8321. The compressed gas entering from the air inlet channel 841 can flow into the spacing area between the inlet of the discharge channel and the outlet of the particle channel 8321, thereby forming a negative pressure.

[0162] The discharge channel includes a central channel 8421 arranged in the center of the seat body 84 and a side channel 8422 whose one end is connected to the central channel 8421. The central channel 8421 is located directly below the particle channel 8321. The size of the central channel 8421 is not smaller than the size of the particle channel 8321. Preferably, the central axes of the central channel 8421 and the particle channel 8321 are collinearly arranged so that the granular medium flowing out of the particle channel 8321 can enter the central channel 8421 as much as possible under the action of negative pressure.

[0163] In this embodiment, a second column 842 is provided at the center of the seat body 84 , and the central channel 8421 is the central hole of the second column 842 .

[0164] The material guide 83 is fixedly arranged in the lower cavity 8121 through the connecting member 85. Figure 4 、 Figure 6 and Figure 8 As shown, the connecting member 85 includes a first connecting portion 851 located at the upper part and a second connecting portion 852 located at the lower part. The first connecting portion 851 is sleeved on the outside of the first column 832 and fixed to the first column 832, and the second connecting portion 852 is sleeved on the outside of the second column 842 and fixed to the second column 842.

[0165] like Figure 26 As shown, the base 84 is further provided with an air inlet chamber 843 connected to the air inlet passage 841, and the lower portion of the lower hopper 812 is completely open. The particle supply mechanism also includes a cyclone separator 86 disposed within the air inlet chamber 843. The inlet of the cyclone separator 86 is connected to the air inlet chamber 843, and the outlet of the cyclone separator 86 is connected to the lower chamber 8121. The cyclone separator 86 can adopt a structure known in the prior art, and its specific structure will not be described in detail. The compressed gas flows into the air inlet chamber 843 through the air inlet passage 841 and enters the cyclone separator 86. After flowing out of the cyclone separator 86, it forms a spiral airflow and enters the lower chamber 8121.

[0166] In this embodiment, Figure 26 As shown, the lower portion of the second connecting portion 852 is pressed onto the cyclone separator 86 , thereby pressing the cyclone separator 86 between the second connecting portion 852 and the seat body 84 , thereby fixing the cyclone separator 86 .

[0167] like Figure 24 、 Figure 26 and Figure 28 As shown, there is a hollow area between the first connecting portion 851 and the second connecting portion 852, so that the airflow in the lower cavity 8121 can flow from the hollow area to the interval area between the inlet of the discharge channel and the outlet of the particle channel 8321.

[0168] In this embodiment, in order to simplify the structure of the entire particle supply mechanism, no sealing design is made between the hopper assembly, the material guide 83 and the lower hopper 812. In this way, the airflow entering the lower cavity 8121 will spirally rise along the side wall of the hopper assembly until it fills the upper cavity 8111 and the lower cavity 8121 above the disc 831, and forms a positive pressure in these areas. In this way, when the compressed gas enters the lower cavity 8121 from the cyclone separator 86, the compressed gas flows from the hollow area between the first connecting part 851 and the second connecting part 852 to the interval area between the inlet of the discharge channel and the outlet of the particle channel 8321, thereby forming a negative pressure.

[0169] like Figure 23 、 Figures 25 to 28 As shown, the particle supply mechanism further includes a silo 87, which is a conical structure with a larger upper portion and a smaller lower portion. The silo 87 is connected to the hopper assembly through a pipeline, and a control valve 88 is provided on the pipeline to control the opening or closing of the pipeline.

[0170] The particle supply mechanism also includes a sensor 89 , which is disposed on the hopper assembly. The sensing end of the sensor 89 extends into the upper cavity 8111 . The sensor 89 is used to monitor the height of the particle medium in the upper cavity 8111 .

[0171] When the level of the granular medium in the upper cavity 8111 is lower than the set level, the control valve 88 opens the pipeline, and the granular medium is fed into the upper cavity 8111 through the silo 87. When the level of the granular medium in the upper cavity 8111 is not lower than the set level, the control valve 88 closes the pipeline, and the granular medium in the silo 87 cannot flow into the upper cavity 8111.

[0172] like Figure 22 As shown, the first air supply mechanism includes a branch air intake line 9, which is connected to the air intake channel 841. A control valve can be set on the branch air intake line 9, and the flow of compressed gas entering the air intake channel 841 can be controlled by the control valve.

[0173] The air duct cleaning mechanism is used to clean the air duct. The air duct cleaning mechanism is arranged on the working bucket 21. When the working bucket 21 slides in the front-back direction, the air duct cleaning mechanism is driven to slide in the front-back direction synchronously. Figure 3 、 Figure 4 、 Figures 29 to 33 As shown, the air duct cleaning mechanism includes a sealing cabin 2', a sealing plate 31', a second nozzle assembly 4' and a second air supply mechanism.

[0174] The lower portion of the sealed cabin 2' is open and is used to cover the upper portion of the wind tube to seal the upper portion of the wind tube. The sealed cabin 2' is mounted on the working bucket 21, and at least a portion of the sealed cabin 2' is slidable in the vertical direction. The working bucket 21 drives the sealed cabin 2' to slide back and forth, thereby moving the sealed cabin 2' to a position corresponding to the wind tube. By sliding all or part of the sealed cabin 2' downward, the lower end of the sealed cabin 2' is placed against the upper end surface of the component where the wind tube is mounted, and the wind tube inlet at the upper end is covered within the sealed cabin 2'.

[0175] Specifically, such as Figures 29 to 33 As shown, the sealed cabin 2' includes a main cabin 21' and a barrier 22' disposed below the main cabin 21'. A support plate 24 is fixedly mounted at the bottom of the working bucket 21. The main cabin 21' is mounted on the support plate 24 and is located at the bottom of the working bucket 21. The working bucket 21 forms the top of the main cabin 21', while the bottom of the main cabin 21' is open. The barrier 22' is an annular structure that is open at the top and bottom. The barrier 22' is disposed below the main cabin 21' in a manner that allows it to slide in the vertical direction.

[0176] The sealed cabin 2' has a first state and a second state. When the sealed cabin 2' is in the first state, the enclosure 22' is mounted on the outside of the lower part of the main cabin body 21', and the lower end of the enclosure 22' is not lower than the lower end of the main cabin body 21'. In this way, when the working bucket 21 drives the sealed cabin 2' to slide in the front-to-back direction, the sealed cabin 2' can be prevented from interfering with other components and affecting the normal sliding of the sealed cabin 2'. When the sealed cabin 2' is in the second state, the enclosure 22' partially extends below the main cabin body 21', and the lower end of the enclosure 22' is abutted against the upper end surface of the component where the wind tube is provided. At this time, there is an overlapping area between the upper part of the enclosure 22' and the lower part of the main cabin body 21', and in the overlapping area, the inner side of the enclosure 22' fits with the outer side of the main cabin body 21' to ensure the sealing performance of the sealed cabin.

[0177] like Figures 29 to 33 As shown, the sealed cabin 2' also includes an eighth drive mechanism 23', which drives the enclosure 22' to slide up and down relative to the main cabin body 21'. The eighth drive mechanism 23' can be positioned on opposite sides of the sealed cabin 2' in the longitudinal direction. This ensures that the enclosure 22' is evenly stressed, preventing uneven force on the enclosure 22', which could cause it to slide and become stuck. The eighth drive mechanism 23' can be a pneumatic cylinder, with the cylinder body fixed to the main cabin body 21' and the piston rod fixed to the enclosure 22'.

[0178] The sealing plate 31' is used to block and seal the lower portion of the wind tube. It is mounted on the working bucket 21 in a vertically slidable manner. The working bucket 21 drives the sealing plate 31' back and forth, moving it to align with the wind tube. By sliding the sealing plate 31' upward, its upper end abuts the lower end of the component housing the wind tube, sealing the outlet at the lower end of the wind tube.

[0179] In this embodiment, the sealing plate 31 ′ is slidably disposed on the support plate 24 in the up-down direction.

[0180] The air duct cleaning mechanism further includes a ninth driving mechanism 32', which drives the sealing plate 31' to slide up and down relative to the support plate 24. The ninth driving mechanism 32' can be a cylinder, the cylinder body of the cylinder is fixedly mounted on the support plate 24, and the piston rod is fixedly mounted on the sealing plate 31'.

[0181] The second nozzle assembly 4' is used to spray high-pressure air into the wind tube. The second nozzle assembly 4' is located in the sealed cabin 2'. When the upper part of the wind tube is sealed by the sealed cabin 2' and the lower part of the wind tube is sealed by the sealing plate 31', the second nozzle assembly 4' is in a sealed space. This can prevent the high-pressure airflow sprayed by the second nozzle assembly 4' from leaking out and reducing the airflow pressure, thereby affecting the cleaning effect. At the same time, it can also prevent dust and other impurities from flying to other parts of the spinning equipment and affecting the cleaning of other parts.

[0182] The second nozzle assembly 4' is movably arranged in the sealed cabin 2'. By adjusting the position of the second nozzle assembly 4', the high-pressure airflow ejected by the second nozzle assembly 4' can fully act on the air duct that needs to be cleaned, thereby improving the cleaning effect.

[0183] The second nozzle assembly 4' can be slidably arranged in the sealed cabin 2' in the left-right direction. The air duct cleaning mechanism also includes a ninth driving mechanism, which is used to drive the second nozzle assembly 4' to slide in the left-right direction. Specifically, the ninth driving mechanism includes a guide rail 51' extending in the left-right direction and a slider 52' ​​that can be slidably arranged on the guide rail 51' along the length extension direction of the guide rail 51'. The guide rail 51' is fixedly arranged on the main cabin body 11, and the second nozzle assembly 4' is arranged on the slider 52'. When the slider 52' ​​slides along the guide rail 51', it drives the second nozzle assembly 4' to slide synchronously.

[0184] The second nozzle assembly 4' can also be slidably disposed in the sealed cabin 2' along the up-down direction, and / or the second nozzle assembly 4' can also be rotatably disposed in the sealed cabin 2'.

[0185] Specifically, such as Figure 34As shown, the second nozzle assembly 4' includes a nozzle body 41' and an air intake shaft 42'. The air intake shaft 42' extends in the up and down directions. The air intake shaft 42' has an air intake channel. The nozzle body 41' is fixedly arranged at the lower part of the air intake shaft 42'. The air intake shaft 42' can slide up and down on a slider 52', and / or the air intake shaft 42' can rotate around its own axis on the slider 52'.

[0186] In this embodiment, the second nozzle assembly 4' can also slide in the up and down directions while rotating. In this way, only one tenth driving mechanism is provided to realize the up and down sliding and rotation of the second nozzle assembly 4', which makes the structure of the cleaning device simple, easy to control, and can also save costs. Specifically, the air intake shaft 42' is a spline shaft, and the cleaning device also includes a driving member 53' fixedly arranged in the slider 52'. The driving member 53' is sleeved on the outside of the spline shaft and cooperates with the spline shaft. When the spline shaft is driven to rotate by the tenth driving mechanism, the second nozzle assembly 4' is driven to rotate synchronously. When the spline shaft rotates, the spline shaft slides up and down relative to the driving member 53' through the cooperation between the spline shaft and the driving member 53', driving the second nozzle assembly 4' to slide up and down synchronously. The tenth driving mechanism can adopt a motor 54'.

[0187] The second air supply mechanism is disposed outside the sealed cabin 2 ′ and is in communication with the second nozzle assembly 4 ′ to provide compressed gas to the second nozzle assembly 4 ′.

[0188] The second air supply mechanism includes an air booster 6'. The outlet of the air booster 6' is connected to the air inlet passage on the air inlet shaft 42' via a pipeline (not shown). After the compressed air passes through the air booster 6', its pressure increases. In this embodiment, the pressure is increased by at least two times. This creates a high-pressure, high-speed jet at the outlet of the second nozzle assembly 4' that acts on the air duct, enhancing the stripping force against dust and other debris, resulting in a more effective cleaning effect.

[0189] A contraction portion 211' whose cross-sectional area gradually decreases from front to back is formed at the rear of the main cabin body 21'. An air outlet is provided at the rear end of the contraction portion 211' for the exhaust gas in the sealed cabin 2' to flow out of the sealed cabin 2'. The air outlet is connected to the treatment box 23, so that the exhaust gas in the sealed cabin 2' flows into the treatment box 23.

[0190] The oil rack / nozzle cleaning mechanism is used to clean the oil rack and nozzle. It is mounted on the work bucket 21. As the work bucket 21 slides forward and backward, it drives the mechanism forward and backward synchronously. The oil rack / nozzle cleaning mechanism includes a third nozzle assembly 2", a water supply mechanism, and a third air supply mechanism.

[0191] like Figure 3 and Figure 4As shown, the third nozzle assembly 2" is slidably arranged on the support plate 24 in the left-right direction. The working bucket 21 drives the third nozzle assembly 2" to slide back and forth, so that the third nozzle assembly 2" is moved to a position corresponding to the oil rack / oil nozzle. By sliding the third nozzle assembly 2" left and right, the high-speed jet formed by the third nozzle assembly 2" can cover the entire range of the oil rack / oil nozzle.

[0192] In this embodiment, the cleaning medium sprayed by the third nozzle assembly 2" is water and compressed gas, and the third air supply mechanism and the water supply mechanism are respectively connected to the third nozzle assembly 2" through pipelines to provide compressed gas and water to the third nozzle assembly 2".

[0193] like Figure 35 As shown, the third nozzle assembly 2 ″ includes a nozzle body 21 ″, a mixing box 22 ″ and a rod body 23 ″, wherein the nozzle body 21 ″ and the mixing box 22 ″ are respectively disposed at two ends of the rod body 23 ″.

[0194] An injection channel is provided in the nozzle body 21 ″, and the injection channel includes a contraction section and an expansion section. Both the contraction section and the expansion section are tapered structures, and the small end of the contraction section is sequentially connected with the small end of the expansion section to form a throat.

[0195] The rod body 23 ″ has a conveying channel, the upper end of the conveying channel is communicated with the cavity of the mixing box 22 ″, and the lower end of the conveying channel is communicated with the contraction section of the nozzle body 21 ″.

[0196] After compressed gas and water are provided to the mixing box 22" through the third air supply mechanism and the water supply mechanism, the water is transported to the nozzle body 21" through the delivery channel under the action of the compressed gas, and forms a high-pressure water jet through the nozzle body 21" to act on the oil rack / oil nozzle, flushing, peeling, breaking up and other destructive effects on the dust, dirt, oil stains, residual impurities, etc. on the oil rack / oil nozzle, thereby achieving a cleaning effect.

[0197] The rod body 23" extends obliquely from rear to front and from top to bottom. Preferably, the rod body 23" is inclined at an angle of 60-75 degrees. This arrangement allows the high-pressure water jet ejected by the nozzle body 21" to more effectively cover the oil rack / oil nozzle.

[0198] The water supply mechanism includes a water tank 3", the outlet of which is connected to the mixing tank 22" via a pipeline, and the inlet of which is connected to a water tank (not shown) located outside the cleaning device via a pipeline. The capacity of the water tank 3" is much larger than that of the third nozzle assembly 2", to ensure the water volume of the third nozzle assembly 2" during operation.

[0199] A control valve is installed on the pipeline between the water storage tank 3" and the mixing tank 22". The control valve can control the opening and closing of the pipeline. When the nozzle body 21" sprays a jet of water for cleaning, the control valve controls the opening of the pipeline. When the oil rack / nozzle needs to be dried after cleaning, the control valve controls the closing of the pipeline.

[0200] The third air supply mechanism includes an air storage box 4", the outlet of which is connected to the mixing box 22" through a pipeline. The capacity of the air storage box 4" is much larger than that of the third nozzle assembly 2", so as to ensure the air volume when the third nozzle assembly 2" is working.

[0201] A control valve is also provided on the pipeline between the air storage tank 4" and the mixing tank 22", which can control the on and off of the pipeline. When the nozzle body 21" sprays water jets for cleaning, the control valve controls the pipeline to open. When cleaning is completed, the control valve controls the pipeline to close.

[0202] The water storage tank 3 ″ and the air storage tank 4 ″ are both arranged on the working bucket 21 .

[0203] The frame 11 can also be set to slide in the left and right directions. By sliding the frame 11 in the left and right directions, the components set thereon can be slid synchronously in the left and right directions. In this way, the nozzle assembly can be moved to different positions of the spinning equipment to perform the cleaning operation of the spinneret.

[0204] like Figure 1 and Figure 2 As shown, the online cleaning device further includes a guide rail 13 extending in the left-right direction, and the guide rail 13 is used to provide guidance for the frame 11 to slide in the left-right direction.

[0205] The online cleaning device also includes a main air supply mechanism, through which air is supplied to the first air supply mechanism, the second air supply mechanism and the third air supply mechanism respectively.

[0206] The main air supply mechanism includes an air source device, a gas channel 131 provided in the guide rail 13 and extending along the length thereof, and a main air intake pipeline 15 connected to the gas channel 131 via a pipe joint 14. The inlet of the gas channel 131 is connected to the air source device via a pipeline, and the outlet of the gas channel 131 is connected to the main air intake pipeline 15. The main air intake pipeline 15 is connected to the air intake channel 841, the air supercharger 6' and the air storage tank 4" via branch air intake pipelines.

[0207] The guide rail 13 not only realizes guidance but also has the function of conveying gas, so that the structure of the entire online cleaning device is simple.

[0208] A self-sealing structure is provided within pipe joint 14, which closes the passageway. When the main air intake line 15 is connected to pipe joint 14, the passageway is open. When the main air intake line 15 is not connected to pipe joint 14, the passageway is closed by the self-sealing structure. Pipe joint 14 can be a blind-plug connector, simplifying its structure and facilitating connection between pipe joint 14 and the main air intake line 15.

[0209] A plurality of pipe joints 14 may be arranged at intervals along the length extension direction of the guide rail 13 , so that when the frame 11 moves along the guide rail 13 to different spinning equipment, compressed gas can be input into the main air inlet line 15 .

[0210] The online cleaning device also includes a controller. The aforementioned motors, cylinders, robotic arm 31, control valves, and air source are all electrically connected to the controller, allowing the controller to control the movements of the various components. The sensors and flow meters are also electrically connected to the controller to send detection signals to the controller.

[0211] The working principle of the online cleaning device for spinning equipment is as follows:

[0212] (1) The working bucket 21 is moved forward until the rear portion of the box 211 abuts against the spinning equipment;

[0213] (2) the side baffle 212 is moved upward to abut against the end face of the spinning device, and the front baffle 213 is moved upward and reciprocatingly until the yarn ejected from the spinneret is cut off, and then the front baffle 213 is moved upward to abut against the end face of the spinning device;

[0214] (3) Slide the enclosure 22' downward relative to the main cabin 21' until its lower end abuts against the upper end surface of the component where the wind tube is provided, and slide the sealing plate 31' upward until its upper end abuts against the lower end surface of the component where the wind tube is provided;

[0215] (4) Adjust the position of the first nozzle assembly 3 to correspond to the position of the spinneret, so that the first nozzle assembly 3 sprays the cleaning medium toward the spinneret; adjust the position of the second nozzle assembly 4' to correspond to the position of the wind tube, so that the second nozzle assembly 4' sprays the cleaning medium toward the wind tube; and make the third nozzle assembly 2" spray the cleaning medium toward the oil rack / nozzle;

[0216] (5) Adjust the position of the first nozzle assembly 3, clamp the sticky plate cake 41 with the clamping assembly and move it to the spinneret position to wipe the spinneret. During this process, the sticky plate cake 41 can be rotated;

[0217] (6) Move the side baffle 212 downward to the initial position, move the front baffle 213 downward to the initial position, slide the enclosure 22' upward to the initial position, slide the sealing plate 31' downward to the initial position, and move the working bucket 21 backward to the initial position;

[0218] (7) The front baffle 213 is moved upward and reciprocatingly until the yarn ejected from the spinneret is cut off, and then the front baffle 213 is moved downward to the initial position.
