Description

Technical Field

[0001] This invention belongs to the technical field of spunlace nonwoven fabric production equipment, and more specifically relates to an online roller cleaning device, which is particularly suitable for wet spunlace production lines. Background Technology

[0002] With the widespread use of nonwoven products in people's daily lives, the number of spunlace nonwoven production lines has increased dramatically in recent years, leading to problems such as market overcapacity and a lack of product variety. To explore new markets, wet spunlace production lines have become the new market darlings, as the washable nonwoven fabrics produced by wet spunlace production lines are currently popular products.

[0003] The hydroentangling machine is one of the core pieces of equipment in a wet hydroentangling production line. The working principle of the hydroentangling machine is as follows: water jets emitted from the hydroentangling heads penetrate the fiber web, and the reflection of the water jets from multiple hydroentangling heads causes the fiber web to solidify into hydroentangled fabric. When using a hydroentangling machine to produce washable nonwoven fabric using the wet hydroentangling process, a small amount of raw material remains on the surface of the outer web of the roller under the impact of the water jets. The uncontrolled shedding of this wet web residue can cause pulp spots on the fabric surface, thus affecting product quality. Therefore, in actual production, the product quality of washable nonwoven fabric is closely related to the cleanliness of the outer web surface of the roller.

[0004] Currently, cleaning the outer screen of the rollers in a wet hydroentangling line requires shutting down the entire production line. Each start-up and shutdown of a wet hydroentangling line not only consumes a significant amount of energy but also requires a large number of on-site personnel. Therefore, the traditional method of cleaning the roller screen by stopping the machine suffers from low cleaning efficiency, high energy waste, high labor intensity, and high operational difficulty. Thus, there is an urgent need to design a device that enables online roller cleaning to improve the current situation where the machine must be stopped to clean the outer screen. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing an online roller cleaning device. This invention enables continuous, non-stop online cleaning of the outer web of the rollers across the width direction during normal production in a wet hydroentangling production line. It efficiently and promptly disperses and recovers wet fiber web residues adhering to the surface of the outer web, effectively preventing sizing spots on the fabric surface caused by residue shedding. This keeps the outer web surface of the rollers clean, significantly improving the product quality of washable nonwoven fabrics. Furthermore, compared to traditional shutdown-based web cleaning, it automates the cleaning process, greatly improves cleaning efficiency, reduces manual labor, reduces energy consumption, lowers production costs, and facilitates operation.

[0006] The objective of this invention can be achieved through the following measures: The present invention provides an online roller cleaning device comprising a square box main frame (providing an installation and support foundation for components such as the sliding double swing arm bracket, drag chain mounting groove, and waste trough frame), a drag chain mounting groove (serving as a motion drag trough for the drag chain) mounted on the lower back of the square box main frame, and a waste trough frame mounted on the front of the square box main frame (the waste trough frame is used in conjunction with the recycling component; the wet fiber web material residue cleaned from the outer mesh of the roller by high-pressure water jets is drawn into the waste trough frame by the negative pressure of a vacuum generator, and then scraped back and forth along the waste trough by a rubber scraper that reciprocates with the recycling sliding frame, thereby scraping the wet fiber web material residue to the waste trough connected to the lower front end of the waste trough). The material pipe discharges), and the linear guide rail (which works with the rolling slider to guide the linear reciprocating motion of the recycling sliding frame) is laid horizontally in the upper part of the inner cavity of the main frame of the square box along the longitudinal direction. Under the drive of the drive component and guided by the two sets of rolling sliders and the linear guide rail, and connected by bolts to the front and rear swing arm beams and the longitudinal connecting plate, the sliding double swing arm bracket can move linearly back and forth. Under the drive of the geared motor, the synchronous belt meshes with the active synchronous pulley and the passive synchronous pulley to perform synchronous belt transmission, and with the limit effect of two sets of photoelectric sensors and limit switches at both ends, the synchronous belt reciprocates within the corresponding limited range as the geared motor continuously switches between forward and reverse. The synchronous belt, through the synchronous belt clamp, drives the sliding double swing arm bracket to perform linear reciprocating motion; the sliding double swing arm bracket, in turn, drives the connected recovery and cleaning components, cable chain, and the high-pressure water and air pipes placed on the cable chain to perform linear reciprocating motion; thus, the high-pressure flushing head, moving in a linear reciprocating motion, can drive the nozzle to perform long-term, all-round, continuous, non-stop online high-pressure cleaning of the rotating roller outer mesh along the width direction. The U-shaped recovery connectors (for mounting the recovery components) are connected to the front ends of the two swing arm beams, and the L-shaped cable chain connectors (for mounting the cable chain) are inverted at the back ends and horizontally cantilevered outwards. The bottom surface of the front swing arm beam is fixed to the synchronous belt to achieve the same... The synchronous belt clamp (the synchronous belt is connected to the sliding double swing arm bracket through the synchronous belt clamp, so that the synchronous belt will drive the sliding double swing arm bracket to perform linear reciprocating motion) is vertically hung in the front and rear U-shaped recycling joints, and drives the rubber scraper to move linearly and reciprocally along the waste trough frame to scrape the recycled wet fiber web material residue towards the discharge port end of the two sets of recycling components (on the one hand, the recycling components provide the installation foundation for the cleaning components; on the other hand, it is used in conjunction with the recycling components and the cleaning components to discharge the wet fiber web material residue cleaned from the outer net of the roller by the high pressure water jet sprayed from the cleaning components into the waste trough of the waste trough frame through the negative pressure of the vacuum generator);Simultaneously, the recycling component drives the rubber scraper to scrape back and forth along the waste trough, thereby scraping the wet fiber web material residue to the waste pipe connected at the bottom front of the waste trough for discharge. Cleaning components, each mounted on the bottom back of the recycling component, supply high-pressure water. High-pressure water from the high-pressure water pipe enters the inner cavity of the high-pressure flushing head through the high-pressure inlet, splitting into several branches leading to various nozzles. High-pressure water jets are then ejected from each nozzle, forming high-pressure water needles. Because these high-pressure water needles also reciprocate linearly with the cleaning component, the high-pressure water needles ejected from nozzles at different angles can continuously and comprehensively clean the rotating roller outer web along its width for an extended period. (Stop-up online high-pressure cleaning), two sets of cable chains are embedded in the cable chain mounting slot, with the front top connected to the L-shaped cable chain joint by bolts, used for towing high-pressure water pipes and high-pressure air pipes; a passive synchronous pulley is installed on the bottom surface of the square box main frame; an active synchronous pulley is connected to the output shaft of the geared motor and simultaneously drives the passive synchronous pulley through the synchronous belt (the active synchronous pulley, passive synchronous pulley, and synchronous belt constitute the synchronous belt drive; under the drive of the geared motor, the active synchronous pulley rotates synchronously, and then drives the passive synchronous pulley to rotate through the meshing transmission of the synchronous belt; with the help of two sets of photoelectric sensors and limit switches at both ends for limiting function). The geared motor continuously switches between forward and reverse rotation based on signals from the photoelectric sensor, and the synchronous belt drive direction also switches accordingly without interruption. This causes the synchronous belt to reciprocate within a defined range as the geared motor continuously switches between forward and reverse rotation. This, in turn, drives the sliding double-swing arm support, recovery assembly, cleaning assembly, cable chain, and the high-pressure water and air hoses placed on the cable chain to reciprocate in a straight line. This linear reciprocating motion of the high-pressure flushing head allows the nozzles to continuously and non-stoply clean the rotating roller outer mesh along its width for an extended period. Two sets of [unclear - possibly referring to a specific type of equipment] are located at the front and middle of the main frame of the square box. Photoelectric sensors and limit switches (the sliding double-swing arm bracket drives the recovery assembly, cleaning assembly, cable chain, and other components to move along with the synchronous belt. When it moves forward and approaches and triggers the photoelectric sensor at the front end of the main frame cavity, or moves backward and approaches and triggers the photoelectric sensor in the middle of the main frame cavity, the geared motor receiving the photoelectric sensor signal immediately changes its rotation direction. The synchronous belt pulls the sliding double-swing arm bracket to move in the opposite direction, thus driving the recovery assembly, cleaning assembly, cable chain, and other components to move in a linear reciprocating motion. The limit switch located next to the photoelectric sensor can immediately stop the machine for protection after triggering, providing safety assurance). The recycling assembly includes a recycling sliding frame consisting of a vertical panel and ear-shaped hanging plates fixed to the front of the vertical panel; an L-shaped rubber scraper connected to the back of the vertical panel; a vacuum generator with an upper outlet elbow penetrating through the vertical panel and its rear outlet facing the inner cavity of the rubber scraper; and a water-absorbing hood that connects to the inner cavity of the vacuum generator and has an arc-shaped opening at the bottom front cut off to fit against the outer mesh of the roller to form a negative pressure recycling area. (The ear-shaped hanging plates are quickly connected to a U-shaped recycling connector via bolts, allowing the recycling assembly to be smoothly and efficiently hung on the front end of the swing arm beam, thus moving linearly back and forth with the sliding double swing arm support. The vertical panel provides the mounting base for the ear-shaped hanging plates, rubber scraper, and vacuum generator. When the rubber scraper moves linearly back and forth with the recycling assembly, it scrapes back and forth along the waste trough, thereby scraping the wet fiber web material residue to the waste pipe connected to the bottom of the front end of the waste trough for discharge. When the quick-connect connector on the vacuum generator is connected to the high-pressure air pipe carried on the drag chain, the negative pressure suction function of the vacuum generator can be realized. On the one hand, it absorbs...) The water hood provides the mounting base for the cleaning assembly; simultaneously, when the high-pressure water jets from the nozzles in the high-pressure flushing head are sprayed through the water needle nozzles on the water suction hood and hit the outer mesh of the roller that fits against the arc-shaped opening of the water suction hood, it prevents the water needles from splashing everywhere; on the other hand, the water suction hood connects the vacuum generator and the outer mesh of the roller and is a component of the negative pressure suction pipeline, that is, after the wet fiber material residue adhering to the outer mesh of the roller is washed off by the high-pressure water jets, it is transferred to the waste tank through the negative pressure suction pipeline formed by the water suction hood and the vacuum generator; quick-connect connectors for inserting high-pressure air pipes are provided on the cylinder wall of the vacuum generator; the cleaning assembly is hung on the back bottom of the water suction hood shell, and a water needle nozzle is opened on the back bottom of the shell to connect to the inner cavity of the water suction hood (so that the high-pressure water jets from the nozzles in the high-pressure flushing head can be smoothly sprayed through the water needle nozzles on the water suction hood and hit the outer mesh of the roller that fits against the arc-shaped opening of the water suction hood, thus washing off the wet fiber material residue adhering to the outer mesh of the roller by the high-pressure water jets); The cleaning assembly consists of a cleaning bracket for connecting the water absorption hood and a high-pressure flushing head horizontally mounted at the bottom of the cleaning bracket. A high-pressure water inlet for quickly connecting a high-pressure water pipe is provided on the back of the high-pressure flushing head, and several nozzles at different angles are provided on the front of the high-pressure flushing head. (After the high-pressure water pipe is quickly connected to the high-pressure water inlet, high-pressure water enters the inner cavity of the high-pressure flushing head from the high-pressure water pipe, and is distributed to the nozzles at different angles through various branches to output multiple high-pressure water needles. The high-pressure water needles pass through the water needle openings on the water absorption hood and can be smoothly sprayed onto the outer mesh of the roller that is in contact with the arc-shaped opening of the water absorption hood, so that the wet fiber web material residues adhering to the outer mesh of the roller are washed off by the high-pressure water needles.)

[0007] The waste trough frame described in this invention consists of a waste trough extending horizontally, front and rear end sealing plates, a back sealing plate, an upper cover plate, and a waste pipe connected to the bottom of the front end of the waste trough. (The wet fiber web material residue adhering to the outer mesh of the roller is washed down by high-pressure water jet and then transferred to the waste trough through a negative pressure suction pipeline composed of a water suction hood and a vacuum generator. After being scraped back and forth by a rubber scraper, the wet fiber web material residue is sent to the waste pipe connected to the bottom of the front end of the waste trough for discharge.) The upper cover plate of the waste trough frame is bolted to the front of the square box main frame.

[0008] The rolling slider described in this invention consists of a vertical plate and two rows of guide wheels mounted on the back of the vertical plate (the rolling slider cooperates with the linear guide rail to provide guidance for the linear reciprocating motion of the retractable sliding frame. The vertical plate provides a mounting base for the guide wheels; at the same time, the rolling slider is connected to the sliding double swing arm bracket through the connection between the vertical plate and the swing arm beam). The vertical plate is bolted to the back end of the swing arm beam, and the two rows of guide wheels roll synchronously along the upper and lower surfaces of the linear guide rail.

[0009] The nozzle described in this invention is a threaded nozzle that is easy to replace; the nozzle can be a nozzle with an open water outlet or a nozzle without an open water outlet. The nozzle type can be selected according to actual needs (the number of water needles can be adjusted according to factors such as the speed of linear reciprocating motion - that is, select the same number of nozzles with water outlets, and select nozzles with closed water outlets for those that are not needed temporarily. This allows for flexible adjustment of the cleaning effect and has the advantages of flexible operation, strong versatility, and wide range of applications).

[0010] The working principle of this invention is as follows: The present invention is designed with a sliding double swing arm bracket that can move linearly back and forth under the driving action of the drive component and guided by two sets of rolling sliders and linear guide rails. Two sets of recovery components mounted on the front of the sliding double swing arm bracket, a cleaning component mounted on the bottom of the back of the recovery components, a drag chain mounted on the back of the sliding double swing arm bracket, and high-pressure water pipes and high-pressure air pipes placed on the drag chain all move linearly back and forth together with the sliding double swing arm bracket. More specifically, when the geared motor is started, the active synchronous pulley rotates synchronously under the drive of the geared motor. It then drives the passive synchronous pulley to rotate through the meshing transmission of the synchronous belt. With the help of two sets of photoelectric sensors and the limit switches at both ends, the geared motor, which receives the signal from the photoelectric sensor, continuously switches between forward and reverse rotation. The direction of the synchronous belt transmission also switches accordingly without interruption. In this way, the synchronous belt will reciprocate within the corresponding limited range as the geared motor continuously switches between forward and reverse rotation. This, in turn, drives the sliding double swing arm bracket, the recovery assembly, the cleaning assembly, the cable chain, and the high-pressure water pipe and high-pressure air pipe placed on the cable chain to reciprocate in a straight line, which are directly or indirectly connected to the synchronous belt. In this way, high-pressure water from the high-pressure water pipe enters the inner cavity of the high-pressure flushing head through the high-pressure water inlet, and is divided into several branches leading to each nozzle. High-pressure water jets are sprayed out from each nozzle to form high-pressure water needles. Since the high-pressure water needles can also perform linear reciprocating motion with the cleaning components, the high-pressure water needles sprayed from nozzles at different angles can perform all-round continuous online high-pressure cleaning of the rotating roller outer mesh along the width direction for a long time, and promptly and efficiently dissipate the wet fiber web residues adhering to the surface of the roller outer mesh. At the same time, the vacuum generator inner cavity connected to the high-pressure air pipe forms a negative pressure. The wet fiber web residues washed off are first sucked out by the negative pressure of the vacuum generator into the waste trough of the waste trough frame, and then scraped by the rubber scraper that scrapes back and forth along the waste trough to be discharged through the waste pipe connected at the bottom front of the waste trough. In this way, the wet fiber web residues washed off the surface of the roller outer mesh can be recovered in a timely and efficient manner. Therefore, this invention enables continuous, non-stop online cleaning of the outer web of the rollers in the width direction for extended periods during normal production of a wet spunlace production line. It effectively and efficiently disperses and recovers wet fiber web residues adhering to the surface of the outer web, not only preventing the formation of sizing spots on the fabric surface due to residue shedding, but also keeping the outer web surface of the rollers clean at all times, greatly improving the product quality of washable nonwoven fabrics. Compared with traditional shutdown cleaning, it also achieves automated cleaning, greatly improves cleaning efficiency, reduces manual intervention, reduces energy consumption, lowers production costs, and facilitates operation.

It efficiently and promptly disperses and recovers wet fiber residue adhering to the roller outer mesh surface, effectively preventing sizing spots on the fabric surface caused by residue shedding. This keeps the roller outer mesh surface clean, significantly improving the product quality of washable nonwoven fabrics.

[0021] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 — Figure 8As shown, an online roller cleaning device of the present invention includes a square box main frame 1 (providing an installation foundation and support foundation for components such as the sliding double swing arm bracket 13, the drag chain mounting groove 9, and the waste trough frame 23 in the present invention), a drag chain mounting groove 9 (serving as the moving drag trough for the drag chain 8) mounted on the lower back of the square box main frame, and a waste trough frame 23 mounted on the front of the square box main frame (the waste trough frame 23 is used in conjunction with the recycling component C to remove the wet fiber web material residue cleaned from the outer mesh of the roller by high-pressure water jets through the negative pressure of the vacuum generator 20). The material is sucked into the waste trough 23-1 of the waste trough frame 23, and then scraped back and forth along the waste trough 23-1 by the rubber scraper 22 that reciprocates with the recycling sliding frame 21, thereby scraping the wet fiber web material residue to the waste pipe 23-5 connected to the bottom of the front end of the waste trough for discharge. The linear guide rail 2 (which works with the rolling slider 11 to guide the linear reciprocating motion of the recycling sliding frame 21) is laid horizontally in the upper part of the inner cavity of the square box main frame along the longitudinal direction. Under the drive of the drive component A and through two sets of rollers, the material is discharged. The sliding double-swing arm bracket 13, which is formed by bolted connection of two front and rear swing arm beams 12 and longitudinal connecting plates 3, is guided by the movable slider 11 and the linear guide rail 2. Driven by the reduction motor 10, the synchronous belt 7 simultaneously engages with the active synchronous pulley 14 and the passive synchronous pulley 4 for synchronous belt transmission. It also utilizes the limiting functions of two sets of photoelectric sensors 5 and limit switches 6 at both ends. The synchronous belt 7 reciprocates within the corresponding limited range as the reduction motor 10 continuously switches between forward and reverse rotation. The synchronous belt 7 also utilizes… The synchronous belt clamp 12-3 drives the sliding double swing arm bracket 13 to perform linear reciprocating motion; the sliding double swing arm bracket 13, in turn, drives the connected recovery component C and cleaning component B, cable chain 8, and the high-pressure water pipe and high-pressure air pipe placed on the cable chain to perform linear reciprocating motion; in this way, the high-pressure flushing head 16, which moves in a linear reciprocating motion, can drive the nozzle 17 to perform long-term, all-round, continuous, non-stop online high-pressure cleaning of the outer mesh of the roller along the width direction. The U-shaped recovery joints 12 are respectively connected to the front ends of the two swing arm beams 12. -1 (for mounting recycling component C), L-shaped drag link 12-2 (for mounting drag chain 8) with the back end upside down and horizontal cantilever extended, and a timing belt clamp 12-3 fixed to the bottom surface of the front swing arm beam 12 for clamping the timing belt 7 to achieve synchronous movement with the timing belt (the timing belt 7 is connected to the sliding double swing arm bracket 13 through the timing belt clamp 12-3, so that the timing belt 7 will drive the sliding double swing arm bracket 13 to perform linear reciprocating motion), and two sets of recycling components C that are vertically mounted in the front and rear U-shaped recycling joints 12-1 and drive the rubber scraper 22 to move linearly and reciprocally along the waste trough frame 23 to scrape the recycled wet fiber web material residue towards the discharge port end (on the one hand, the recycling component C provides an installation base for the cleaning component B).On the other hand, in conjunction with the recycling component C and the cleaning component B, the wet fiber web material residue cleaned from the outer screen 25 of the roller by the high-pressure water jets sprayed from the cleaning component B is sucked out by the negative pressure of the vacuum generator 20 and discharged into the waste trough 23-1 of the waste trough frame 23; at the same time, the recycling component C drives the rubber scraper 22 to scrape back and forth along the waste trough 23-1, thereby scraping the wet fiber web material residue to the waste pipe 23-5 connected to the bottom of the front end of the waste trough for discharge. The cleaning component B, which is respectively hung on the bottom of the back of the recycling component for supplying high-pressure water (the high-pressure water in the high-pressure water pipe enters the inner cavity of the high-pressure flushing head 16 through the high-pressure water inlet 15, and is divided into several branches leading to each nozzle 17, from which high-pressure water jets are sprayed out to form high-pressure water jets. Since the high-pressure water jets can also perform linear reciprocating motion with the cleaning component B, the high-pressure water jets sprayed from the nozzles 17 at different angles can clean the outer screen of the roller for a long time along the width direction. (All-round continuous non-stop online high-pressure cleaning), embedded in the cable chain mounting groove 9, with the front top connected to the L-shaped cable chain head 12-2 by bolts, used for towing high-pressure water pipes and high-pressure air pipes, two sets of cable chains 8, mounted on the bottom surface of the cavity of the square box main frame 1, a passive synchronous pulley 4, connected to the output shaft of the geared motor 10, and simultaneously driven by the synchronous belt 7 to drive the passive synchronous pulley 4 synchronously (the synchronous belt drive is composed of the active synchronous pulley 14, the passive synchronous pulley 4, and the synchronous belt 7; under the drive of the geared motor 10, the active synchronous pulley 14 rotates synchronously, and drives the passive synchronous pulley 4 to rotate through the meshing transmission of the synchronous belt 7; with the limiting effect of the two sets of photoelectric sensors 5 and the two ends of the limit switch 6, the geared motor 10 continuously switches between forward and reverse rotation, and the synchronous belt drive direction also switches accordingly without interruption, so the synchronous belt 7 will reciprocate within the corresponding limited range as the geared motor 10 continuously switches between forward and reverse rotation);This, in turn, drives the sliding double swing arm bracket 13, the recovery component C, the cleaning component B, the cable chain 8, and the high-pressure water pipe and high-pressure air pipe placed on the cable chain to reciprocate in a straight line. In this way, the high-pressure flushing head 16, which reciprocates in a straight line, can drive the nozzle 17 to perform long-term, all-round, continuous, non-stop online high-pressure cleaning of the outer mesh of the roller along the width direction. Two sets of photoelectric sensors 5 and limit switches 6 are set at the front end and middle of the inner cavity of the square box main frame 1 (the sliding double swing arm bracket 13 drives the recovery component C, the cleaning component B, and the cable chain). Components 8 move together with the synchronous belt 7. When the current moves close to and triggers the photoelectric sensor 5 at the front end of the main frame 1's inner cavity, or moves back to and triggers the photoelectric sensor 5 in the middle of the main frame 1's inner cavity, the reduction motor 10 immediately changes its rotation direction. The synchronous belt 7 pulls the sliding double swing arm bracket 13 to move in the opposite direction. In this way, the sliding double swing arm bracket 13 drives the recovery component C, cleaning component B, cable chain 8, and other components to move in a linear reciprocating motion. The limit switch 6, located next to the photoelectric sensor 5, can immediately stop the machine for protection after triggering, providing safety assurance. The recycling component C includes a recycling sliding frame 21 consisting of a vertical panel 21-1 and an ear-shaped hanging plate 21-2 fixed to the front of the vertical panel; an L-shaped rubber scraper 22 connected to the back of the vertical panel; a vacuum generator 20 with an upper outlet elbow penetrating the vertical panel and its rear outlet facing the inner cavity of the rubber scraper; and a water-absorbing hood 19 that connects to the inner cavity of the vacuum generator and has an arc-shaped opening at the bottom front that is obliquely cut to fit against the outer mesh 25 of the roller to form a negative pressure recycling zone I. (The ear-shaped hanging plate 21-2 is quickly connected to the U-shaped recycling connector 12 via bolts.) -1 allows the recycling component C to be smoothly and efficiently mounted on the front end of the swing arm beam 12, thus moving linearly back and forth with the sliding double swing arm bracket 13. The vertical panel 21-1 provides the mounting base for the ear-shaped hanging plate 21-2, the rubber scraper 22, and the vacuum generator 20. When the rubber scraper 22 moves linearly back and forth with the recycling component C, it scrapes back and forth along the waste trough 23-1, thereby scraping the wet fiber web material residue to the waste pipe 23-5 connected at the bottom of the front end of the waste trough for discharge. When the quick-connect connector 24 on the vacuum generator 20 is connected to the high-pressure air pipe carried on the drag chain 8, the negative pressure suction function of the vacuum generator 20 can be realized. On the one hand, the water suction hood 19 provides the mounting base for the cleaning component B; at the same time, when the high-pressure water needles sprayed from the nozzle 17 in the high-pressure flushing head 16 are sprayed through the water needle port 19-1 on the water suction hood 19 onto the roller outer mesh 25 that fits with the arc-shaped opening of the water suction hood, the water suction hood 19... 9 can prevent the reflected water needles from splashing everywhere; on the other hand, the water suction cover 19 is connected between the vacuum generator 20 and the outer net of the roller 25, and is a component of the negative pressure suction pipeline. That is, after the wet fiber material residue adhering to the outer net of the roller 25 is washed off by the high pressure water needle, it is transferred to the waste tank 23-1 through the negative pressure suction pipeline formed by the water suction cover 19 and the vacuum generator 20. A quick connector 24 for inserting a high pressure air pipe is provided on the cylinder wall of the vacuum generator 20. The cleaning component B is hung on the back of the bottom of the water suction cover, and a water needle port 19-1 communicating with the inner cavity of the water suction cover is opened on the back of the bottom of the cover. (In this way, the high pressure water needles sprayed by the nozzle 17 in the high pressure flushing head 16 can be smoothly sprayed onto the outer net of the roller 25 that is in contact with the arc-shaped opening of the water suction cover 19 through the water needle port 19-1 opened on the water suction cover 19, so that the wet fiber material residue adhering to the outer net of the roller 25 is washed off by the high pressure water needle). The cleaning assembly B consists of a cleaning bracket 18 for connecting the water absorption hood 19 and a high-pressure flushing head 16 horizontally mounted at the bottom of the cleaning bracket. A high-pressure water inlet 15 for quickly connecting a high-pressure water pipe is provided on the back of the high-pressure flushing head 16. Several nozzles 17 at different angles are provided on the front of the high-pressure flushing head 16. (After the high-pressure water pipe is quickly connected to the high-pressure water inlet 15, the high-pressure water enters the inner cavity of the high-pressure flushing head 16 from the high-pressure water pipe, and is distributed to the nozzles 17 at different angles through various branches to output multiple high-pressure water needles. The high-pressure water needles pass through the water needle openings 19-1 on the water absorption hood 19 and can be smoothly sprayed onto the outer mesh 25 of the roller that is in contact with the arc-shaped opening of the water absorption hood, so that the wet fiber web material residues adhering to the outer mesh of the roller are washed off by the high-pressure water needles.)

[0022] The waste trough frame 23 described in this invention consists of a waste trough 23-1 extending horizontally, front and rear end sealing plates 23-2, a back sealing plate 23-3, an upper cover plate 23-4, and a waste pipe 23-5 connected to the bottom of the front end of the waste trough. (The wet fiber web material residue adhering to the outer mesh of the roller is washed down by high-pressure water jet and transferred to the waste trough 23-1 through the negative pressure suction pipe formed by the water suction hood 19 and the vacuum generator 20. Then, the wet fiber web material residue is scraped back and forth by the rubber scraper 22 and discharged through the waste pipe 23-5 connected to the bottom of the front end of the waste trough.) The upper cover plate 23-4 in the waste trough frame 23 is hung on the front of the square box main frame by bolts.

[0023] The rolling slider 11 described in this invention is composed of a vertical plate 11-1 and two rows of guide wheels 11-2 mounted on the back of the vertical plate (the rolling slider 11 cooperates with the linear guide rail 2 to provide guidance for the linear reciprocating motion of the retractable sliding frame 21. The vertical plate 11-1 provides a mounting base for the guide wheels 11-2; at the same time, the rolling slider 11 is connected to the sliding double swing arm bracket 13 through the connection between the vertical plate 11-1 and the swing arm beam 12). The vertical plate 11-1 is bolted to the back end of the swing arm beam 12, and the two rows of guide wheels 11-2 roll synchronously along the upper and lower surfaces of the linear guide rail 2.

[0024] The nozzle 17 described in this invention is a threaded nozzle that is easy to replace; the nozzle 17 can be a nozzle with an open water outlet or a nozzle with an closed water outlet. The nozzle type can be selected according to actual needs (the number of water needles can be adjusted according to factors such as the speed of linear reciprocating motion - that is, select the same number of nozzles with water outlets, and select nozzles with closed water outlets for those that are not needed temporarily. This allows for flexible adjustment of the cleaning effect and has the advantages of flexible operation, strong versatility, and wide range of applications).

[0025] The specific uses of this invention are as follows: Assemble the invention according to the above structural description and the positional relationship shown in the attached drawings. Connect the high-pressure water pipe and high-pressure air pipe, which are placed on the cable chain 8, to the high-pressure water inlet 15 in the high-pressure flushing head 16 and the quick-connect connector 24 on the vacuum generator 20, respectively. Then the invention can be started to work normally. That is, start the geared motor 10 to rotate. Driven by the geared motor 10, the active synchronous pulley 14 rotates synchronously, and drives the passive synchronous pulley 4 to rotate through the meshing transmission of the synchronous belt 7. With the limiting effect of the two sets of photoelectric sensors 5 and the limit switches 6 at both ends, the geared motor 10, which receives the signal from the photoelectric sensor 5, continuously switches between forward and reverse rotation. The synchronous belt transmission direction also switches continuously accordingly. In this way, the synchronous belt 7 will reciprocate within the corresponding limited range as the geared motor 10 continuously switches between forward and reverse rotation. This drives the sliding double swing arm bracket 13, the recovery component C, the cleaning component B, the cable chain 8, and the high-pressure water pipe and high-pressure air pipe placed on the cable chain to reciprocate in a straight line. High-pressure water from the high-pressure water pipe enters the inner cavity of the high-pressure flushing head 16 through the high-pressure water inlet 15, and is divided into several branches leading to each nozzle 17. High-pressure water jets are ejected from each nozzle 17 to form high-pressure water needles. Since the high-pressure water needles can also reciprocate linearly with the cleaning component B, the high-pressure water needles ejected from the nozzles 17 at different angles can perform continuous, non-stop online high-pressure cleaning of the rotating roller outer mesh along the width direction for a long time, effectively and efficiently dispersing the wet fiber residue adhering to the surface of the roller outer mesh. At the same time, a negative pressure is formed in the inner cavity of the vacuum generator 20 connected to the high-pressure air pipe. The wet fiber residue washed off is first sucked out by the negative pressure of the vacuum generator 20 into the waste trough 23-1 of the waste trough frame 23, and then scraped by the rubber scraper 22 that moves back and forth along the waste trough 23-1 to be discharged through the waste pipe 23-5 connected to the bottom front end of the waste trough. This allows for the timely and efficient recovery of the wet fiber residue washed off the surface of the roller outer mesh. Therefore, this invention enables continuous, non-stop online cleaning of the rotating roller outer mesh in the width direction for an extended period during normal production of a wet hydroentangling production line. It effectively and efficiently disperses and recovers wet fiber residues adhering to the surface of the roller outer mesh, not only effectively preventing the appearance of sizing spots on the fabric surface due to residue shedding, but also keeping the roller outer mesh surface clean at all times, greatly improving the product quality of washable nonwoven fabrics. Compared with traditional shutdown cleaning, it also achieves automated cleaning, greatly improves cleaning efficiency, reduces manual intervention, reduces energy consumption, lowers production costs, and facilitates operation.
