Description

Technical Field

[0001] This invention relates to the field of tin-plating wire production and processing technology, and in particular to a device for removing tin ash from the surface of tin-plating wire. Background Technology

[0002] During the production and processing of tin-plated wire (such as copper wire with tin plating), a layer of fine tin ash (tin oxide and powder) is easily generated on the surface of the wire due to high-temperature oxidation or friction. If this tin ash is not removed in time, it will seriously affect the conductivity, solderability and subsequent insulation coating quality of the wire.

[0003] Currently, the common method for removing tin ash is to pass the tin-plating line through multiple wiping cloths or felts, and remove the surface tin ash through physical friction. However, in actual operation, after a period of use, a large amount of tin ash will quickly accumulate on the surface of the wiping cloth, resulting in a significant decrease in cleaning ability. In order to ensure the cleaning effect, operators need to frequently stop the machine and manually replace or clean the wiping cloth. This is not only cumbersome and labor-intensive, but also interrupts continuous production operations and reduces production efficiency.

[0004] To address this problem, we propose a device for removing tin ash from the surface of tin-plated wires. Summary of the Invention

[0005] The purpose of this invention is to provide a device for removing tin ash from the surface of a tin-plating line, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A device for removing tin ash from the surface of a tin-plated wire includes a frame. Four drive rollers are rotatably mounted at the top, bottom, left, and right corners of the frame. A wiping belt is sleeved around each of the four drive rollers, forming a U-shaped structure and dividing the wiping belt into four sequentially connected working sections: a wiping section, a dust removal section, a cleaning section, and a dewatering section. A main motor is connected to the shaft end of one of the drive rollers. A cleaning tank is also installed under the frame, with the cleaning section of the wiping belt submerged in it. A cleaning roller brush is installed inside the cleaning tank, and a moving component is mounted on the outer shell of the cleaning tank. This moving component controls the cleaning roller brush to reciprocate along the extension direction of the cleaning section of the wiping belt. For cleaning, a scraper bar is closely attached to the outer side of the dust removal section of the wiping belt, and a pair of squeezing rollers are symmetrically attached to the inner and outer sides of the water removal section of the wiping belt. Adjustment seats are installed at both ends of the squeezing rollers and the scraper bar. A back plate is installed on the rear side of the cleaning tank, and a limit component is installed between the back plate and each adjustment seat on the rear side. The limit component is used to restrict the movement direction of the scraper bar and the pair of squeezing rollers. A linkage component is connected between the movement component and each adjustment seat. When the movement component controls the horizontal reciprocating movement of the cleaning roller brush, it drives the scraper bar to move vertically reciprocating to scrape the dust removal section, and also drives the pair of squeezing rollers to move vertically reciprocating to squeeze the water removal section.

[0007] In a further embodiment, the transmission roller includes a central rod, with gear disks symmetrically and coaxially fixed at both ends of the central rod, and a limit disk coaxially fixed at the outer end of the gear disks. The dust-wiping belt includes a gear belt that matches the gear disks, and a towel strip is detachably installed in the middle of the gear belt.

[0008] In a further embodiment, the thickness of the towel strip is greater than the thickness of the gear belt, and the towel strip is detachably connected to the gear belt by snap fasteners or Velcro, with snap fasteners or Velcro distributed at the connection edge between the towel strip and the gear belt.

[0009] In a further embodiment, the moving component includes a top frame spanning the inner and outer sides of the upper end face of the cleaning tank. A drive gear is rotatably mounted inside the top frame, and an auxiliary motor is connected to the outer shaft end of the drive gear. A rack is fixed along the length direction on the upper end face of the cleaning tank, and the drive gear and the rack are meshed vertically. A vertical connecting box is fixed to one end of the top frame extending into the cleaning tank, and the bottom end of the connecting box is rotatably connected to the shaft end of the cleaning roller brush. A first slider is fixed to one end of the top frame extending out of the cleaning tank, and a first slide rail that cooperates with the first slider is fixed on the outer shell of the cleaning tank.

[0010] In a further embodiment, a pair of conveyor wheels are rotatably mounted inside the connecting box. One conveyor wheel is coaxially connected to the drive gear, and the other conveyor wheel is coaxially connected to the cleaning roller brush. A conveyor belt is sleeved between the two conveyor wheels.

[0011] In a further embodiment, the linkage component includes a stand fixed on the first slider, the top of which is connected to a downwardly extending inclined guide rail frame, and the upper and lower surfaces of the inner groove of the inclined guide rail frame are provided with V-shaped track grooves, and V-shaped rollers are rotatably installed in the V-shaped track grooves, and the V-shaped rollers are rotatably connected to the adjustment seat.

[0012] In a further embodiment, the adjusting seat includes an end seat and an adjusting plate, and the end seat is connected to the end of the scraper rod or the squeezing roller. The adjusting plate has an adjusting groove opened laterally inside, and an adjusting block is connected to one end of the end seat that extends into the adjusting groove. The adjusting block is used to slide in the adjusting groove, and an adjusting rod is connected to one end of the adjusting block that extends out of the adjusting groove. A locking nut is screwed onto the adjusting rod. A connecting seat is fixed under the adjusting plate.

[0013] In a further embodiment, the scraper rod has a hollow structure, and an elongated groove is provided at one end of the scraper rod near the surface of the ash removal section. The rear end of the scraper rod passes through the end seat of the adjusting seat and is connected to an air extraction pipe. The air extraction pipe extends to the back side of the back plate and is connected to the air extraction machine through a hose.

[0014] In a further embodiment, the squeezing roller has a hollow structure and several radial air jet holes are provided on the outer circumferential surface of the squeezing roller. The squeezing roller is rotatably connected to the end seat of the adjusting seat, and the rear end of the squeezing roller passes through the end seat and is connected to an air supply pipe through a rotary joint. The tail ends of the air supply pipes of the two squeezing rollers pass through to the back side of the back plate and are connected to each other through a Y-type joint. The Y-type joint is connected to the air supply pump through a hose.

[0015] In a further embodiment, the limiting component includes a second slide rail vertically fixed to the front side of the back plate and a second slider slidably sleeved on the outside of the second slide rail, the second slider being fixed to a connecting seat near the adjusting seat of the back plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention designs the wiping belt as a loop-shaped circulating structure, and sequentially sets up wiping section, dust removal section, washing section and water removal section. After completing the wiping work, the wiping belt can automatically enter the subsequent dust scraping, washing and water squeezing drying stages, realizing online automatic circulation cleaning of the wiping belt. This allows the wiping belt to be recycled immediately without frequent manual replacement, ensuring cleaning capability for long-term continuous operation.

[0017] The invention features a scraper bar that fits closely to the outer surface of the wiping belt, which can physically scrape off most of the attached tin ash; a cleaning roller brush, in its reciprocating motion, scrubs the wiping belt immersed in the cleaning solution, which can penetrate deep into the fibers to remove tiny tin ash particles; and a pair of wringing rollers, in their vertical reciprocating motion, produce a squeezing effect similar to wringing a towel, which can efficiently squeeze out the residual water after cleaning.

[0018] This invention utilizes a single moving component to simultaneously drive a cleaning roller for reciprocating cleaning, and a linkage component to drive a scraper and a squeezing roller for reciprocating motion. This design requires only one power source to simultaneously complete the three actions of scraping off surface tin ash, brushing the ash-wiping belt, and squeezing out the moisture from the ash-wiping belt. The highly integrated mechanical structure makes the three actions of scraping, brushing, and squeezing independent yet coordinated, significantly improving the cleaning efficiency and effect of the ash-wiping belt.

[0019] The present invention integrates a vacuum pipe and a vacuum pump into the scraper rod to create a negative pressure suction structure, so that while scraping off dust particles, the scraped-off tin ash is promptly sucked away to avoid secondary pollution.

[0020] The present invention integrates air supply structures such as air jet holes, air supply pipes and air supply pumps on the water squeezing roller, so as to improve the fluffiness of the surface fibers of the wiping belt through the action of air jet impact, avoid the wiping belt being too flat after being squeezed, which would affect the wiping effect, and keep the wiping belt in the best condition before entering the next round of wiping.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-8A device for removing tin ash from the surface of tin-plated wire includes a rectangular frame frame 1. At each of the four corners of the frame 1 (upper left, upper right, lower left, and lower right), a drive roller 2 is rotatably mounted via bearing seats. A closed-loop ash-removing belt 3 is connected to all four drive rollers 2. The four drive rollers 2 tension and constrain the ash-removing belt 3 into a loop-shaped rectangular ring. This rectangular ring forms four continuous working sections along the direction of rotation of the ash-removing belt 3: a horizontal section on the upper layer of the frame 1 is the ash-removing section; a vertical section on the right side of the frame 1 is the ash-removing section; and a vertical section on the lower layer of the frame 1 is the ash-removing section. The horizontal section of the layer is the cleaning section, and the vertical section located on the left side of the frame 1 is the dewatering section. One of the drive rollers 2 has a main motor 4 connected to its shaft end via a coupling. The main motor 4 is fixed to the outside of the frame 1 and is used to drive the dust removal belt 3 to circulate at a set speed. Below the frame 1, that is, below the cleaning section, a cleaning tank 5 with an open top is fixedly installed. The cleaning tank 5 is filled with cleaning liquid, such as water-based cleaning agent or industrial alcohol, selected according to the characteristics of tin ash. The bottom of the cleaning tank 5 is equipped with a drain pipe with a rubber stopper. The cleaning section of the dust removal belt 3 is completely submerged below the surface of the cleaning liquid.

[0027] A cleaning roller brush 6 is also installed inside the cleaning tank 5. The bristles of the cleaning roller brush 6 are in close contact with the outer surface of the cleaning section of the dust removal belt 3. A moving component 7 is installed on the outer shell of the cleaning tank 5. The moving component 7 is used to drive the cleaning roller brush 6 to move back and forth along the extension direction of the cleaning section of the dust removal belt 3, that is, in the horizontal direction, and at the same time drive the cleaning roller brush 6 to rotate itself, so as to brush the dust removal belt 3 in the submerged state.

[0028] A horizontal, longitudinally extending scraper bar 10 is closely attached to the outer side of the ash removal section of the ash-wiping belt 3. A pair of water-squeezing rollers 11 are symmetrically attached to the inner and outer sides of the water removal section of the ash-wiping belt 3. The two water-squeezing rollers 11 also extend longitudinally, and their axes are parallel to the drive roller 2. The gap between them is slightly smaller than the thickness of the ash-wiping belt 3, forming a squeezing fit. An adjusting seat 9 is installed at both ends of the scraper bar 10 and at both ends of the two water-squeezing rollers 11. A vertical back plate 12 is fixedly installed on the rear side of the cleaning tank 5. A limit assembly 13 is installed between the back plate 12 and each adjusting seat 9 located on the rear side. The limit assembly 13 restricts the movement direction of the scraper bar 10 and the pair of water-squeezing rollers 11, allowing them to move only vertically back and forth, and preventing them from moving forward. For horizontal movement, preferably, a front upright plate can also be installed on the front side of the cleaning tank 5, and a limiting component 13 can be installed on the corresponding back plate 12, so that the limiting component 13 is symmetrical front and back, and the limiting effect on the scraper rod 10 and the wringer 11 is more balanced. A linkage component 8 is connected between the moving component 7 and each adjusting seat 9. When the moving component 7 drives the cleaning roller brush 6 to move horizontally back and forth, the linkage component 8 simultaneously drives the scraper rod 10 to move vertically back and forth along the surface of the dust removal section to scrape and remove the tin ash attached to the surface of the wiping belt 3; at the same time, it also drives a pair of wringer rollers 11 to move vertically back and forth along the surface of the dewatering section to repeatedly squeeze and drain the cleaned wiping belt 3, thus realizing the linkage effect of one power source driving three cleaning sub-actions at the same time.

[0029] The transmission roller 2 specifically includes a metal central rod 21. The two ends of the central rod 21 are symmetrically and coaxially fixed with gear disks 22. The module and number of teeth of the gear disks 22 are set according to the required transmission accuracy. At the outer end of each gear disk 22, that is, the end away from the middle of the central rod 21, a limiting disk 23 is further coaxially fixed. The diameter of the limiting disk 23 is larger than the tooth tip circle diameter of the gear disk 22, which is used to prevent the dust wiping belt 3 from axially moving during operation.

[0030] The dust-wiping belt 3 includes an annular gear belt 31. The inner side of the gear belt 31 has a toothed structure that fully meshes with the gear disk 22. Through the toothed engagement, the transmission roller 2 and the dust-wiping belt 3 are not prone to slippage, and the dust-wiping belt 3 will not move during the cleaning operation, thus maintaining the stability of the dust-wiping belt 3. The gear belt 31 is made of wear-resistant and flexible polyurethane material. In the middle area of ​​the gear belt 31, that is, on the side away from the toothed structure, a towel strip 32 is detachably installed. Preferably, the towel strip 32 is made of microfiber towel material, which has high dust absorption, high water absorption and good wear resistance.

[0031] The detachable method is through Velcro or snap fasteners. Specifically, the outer surface of the gear belt 31 is sewn with hook-and-loop fasteners along the edge, and the inner surface of the towel strip 32 is sewn with corresponding hook-and-loop fasteners along the edge; or the outer surface of the gear belt 31 is fixed with several female snap fasteners at intervals along the edge, and the inner surface of the towel strip 32 is fixed with several female snap fasteners. The thickness of the towel strip 32 is designed to be 1.5-3 times the thickness of the gear belt 31 to ensure that the towel strip 32 makes priority contact with the tin-plating wire during operation, while the gear belt 31 does not rub directly against the workpiece. When the towel strip 32 is severely worn and needs to be replaced, it can be simply peeled off from the gear belt 31 and a new towel strip 32 can be attached without replacing the entire dust-wiping belt 3.

[0032] The moving component 7 includes a top frame 71 spanning the inner and outer sides of the upper end face of the cleaning tank 5 housing. The top frame 71 is inverted U-shaped and welded from metal sheets. A drive gear 72 is rotatably mounted inside the horizontal portion of the top frame 71 via bearings. The shaft end of the drive gear 72 extends horizontally out of the top frame 71 and is connected to an auxiliary motor 75. The auxiliary motor 75 is a reversible servo motor or stepper motor. A rack 73 is fixed along the length of one upper end face of the cleaning tank 5. The drive gear 72 meshes vertically with the rack 73. One end of the top frame 71 extending into the cleaning tank 5 is fixed with a… A vertically arranged connecting box 74 is a hollow rectangular box with two rotatably mounted inside. One of the connecting boxes 741 is coaxially connected to the drive gear 72 via a horizontal shaft, and the other connecting box 741 is coaxially connected to the shaft end of the cleaning roller brush 6 via a vertical shaft. A synchronous conveyor belt 742 is sleeved between the two connecting boxes 741. A first slider 76 is fixed at one end of the top frame 71 outside the cleaning tank 5. A first slide rail 77 is fixed on the outer wall of the cleaning tank 5 and slides with the first slider 76. The extension direction of the first slide rail 77 is parallel to the rack 73.

[0033] When the auxiliary motor 75 drives the drive gear 72 to rotate, the drive gear 72 meshes with the rack 73 to generate a horizontal thrust, which drives the entire moving assembly 7 to move horizontally along the first slide rail 77. At the same time, the rotation of the drive gear 72 is transmitted to the cleaning roller brush 6 through the transmission wheel 741 and the transmission belt 742, so that the cleaning roller brush 6 rotates at high speed while moving horizontally. The auxiliary motor 75 periodically reverses direction, so that the cleaning roller brush 6 can be brushed back and forth in the cleaning section. In order to ensure the driving effect of forced rotation of the cleaning roller brush 6, the transmission wheel 741 and the transmission belt 742 can preferably be a gear and toothed belt structure to effectively reduce the problem of slippage.

[0034] Each adjusting seat 9 includes an end seat 91 and an adjusting plate 92. The end seat 91 is block-shaped and is used to fix it to the end of the scraper rod 10 or to rotate it to the end of the squeezing roller 11 via a bearing. The adjusting plate 92 is a rectangular plate with an oblong adjusting groove in the middle. An adjusting block 911 extends from one side of the end seat 91 toward the adjusting plate 92. The adjusting block 911 slides in the adjusting groove, and the end of the adjusting block 911 extends out of the adjusting groove and is fixed with an adjusting rod 912 with external threads. A locking nut 93 is screwed onto the adjusting rod 912. The locking nut 93 presses against the outer side of the adjusting plate 92, thereby locking the relative position of the end seat 91 and the adjusting plate 92. By changing the position of the adjusting block 911 in the adjusting groove, the pressure between the scraper rod 10 and the wiping belt 3 can be changed, or the clamping force between the pair of squeezing rollers 11 can be changed. A connecting seat 921 is fixed at the lower end of the adjusting plate 92.

[0035] The linkage component 8 includes a stand 81, the bottom of which is fixed to the first slider 76. The top of the stand 81 is connected to an inclined guide rail 82 that extends downward and to the side. The inclined guide rail 82 has a rectangular slot inside. The upper and lower surfaces inside the slot are provided with parallel V-shaped track grooves 83. The inclination angle of the V-shaped track grooves 83 is preferably between 30-45°. A V-shaped roller 84 is rolled inside the V-shaped track groove 83. The V-shaped roller 84 is rotatably connected to the connecting seat 921 of the adjusting seat 9. When the first slider 76 drives the stand 81 and the inclined guide rail 82 to move horizontally, the V-shaped roller 84 will roll along the V-shaped track groove 83. Since the V-shaped track groove 83 is inclined, it can drive the adjusting seat 9 to move vertically during the rolling process, thereby traction of the scraper rod 10 or the water squeezing roller 11 to move vertically back and forth.

[0036] The limiting component 13 includes two vertical parallel second slide rails 131 fixed to the front side of the back plate 12, and a second slider 132 slidably sleeved on the second slide rails 131. Each second slider 132 is fixedly connected to the connecting seat 921 or the back of the adjusting plate 92 of the corresponding adjusting seat 9 by screws. Therefore, when the linkage component 8 pulls the adjusting seat 9, the adjusting seat 9 can only make vertical reciprocating movements along the second slide rails 131, and cannot be horizontally offset or rotated, ensuring that the scraper rod 10 and the water squeezing roller 11 always remain parallel and well-fitted to the surface of the wiping belt 3.

[0037] The scraper rod 10 is made of hollow stainless steel tube. A long slot with a width of 1-3mm is opened along the axial direction on one side of the scraper rod 10 near the surface of the ash removal section of the ash removal belt 3. This slot is used to collect the scraped tin ash. At the rear end of the scraper rod 10, that is, the end near the back plate 12, a suction pipe 101 is sealed and connected through the end seat 91 of the adjusting seat 9. The suction pipe 101 extends through the back plate 12 to its back side and is connected to the air inlet of a vacuum pump 102 through a hose. The air outlet of the vacuum pump 102 can be connected to a bag filter through a pipe to filter and purify the gas containing tin ash. The bottom of the bag filter is equipped with a dust hopper to collect tin ash dust. The exhaust port of the bag filter is connected to the outdoor or workshop return air system. During operation, the vacuum pump 102 is kept on to create a negative pressure inside the scraper rod 10, which will suck away the scraped tin ash dust in time and avoid secondary dust.

[0038] The squeezing roller 11 is also made of hollow stainless steel or rigid plastic tubing. Multiple radial air jet holes, arranged in a spiral or array, are formed on its outer circumferential surface. The hole diameter is 0.5-1 mm. The end of the squeezing roller 11 is rotatably connected to the end seat 91 of the adjusting seat 9 via a bearing, ensuring that the squeezing roller 11 can rotate freely to reduce friction. The rear end of the squeezing roller 11 passes through the end seat 91 and is connected to an air supply pipe 112 via a rotary joint 111. The tail ends of the air supply pipes 112 of the two squeezing rollers 11 respectively pass through the back plate 12 to the back side and are connected via a Y-shaped... After the type connector 113 is combined, it is connected to the air outlet of an air supply pump 114 through a hose. The air inlet of the air supply pump 114 is connected to an external air filter through a pipe. The air filter is equipped with a filter element with a filtration accuracy of not less than 10μm to filter out dust particles in the intake air and prevent the air jet holes of the water squeezing roller 11 from being blocked. The compressed air output by the air supply pump 114 is blown onto the surface of the dust wiping belt 3 through the air jet holes on the surface of the water squeezing roller 11. The addition of gas purging on the basis of mechanical squeezing can improve the fluffiness of the dust wiping belt 3 while squeezing and drying the dust.

[0039] To achieve coordinated and automatic operation of all mechanisms, this device is also equipped with an electrical control box 14. The control box 14 is equipped with a programmable controller, contactor, thermal relay, intermediate relay, push button switch and indicator light. The input end of the control box is connected to the proximity switch installed at both ends of the stroke of the moving component 7, the liquid level switch in the cleaning tank 5 and the emergency stop button; the output end is connected to the power circuit of the main motor 4, the auxiliary motor 75, the air pump 102 and the air supply pump 114 respectively.

[0040] The control box 14 controls each device according to the preset logic as follows: A complete work cycle is divided into two alternating stages: Cleaning stage: The wiping belt 3 remains stationary, the scraper bar 10 scrapes vertically back and forth in the ash removal section, the cleaning roller brush 6 rotates horizontally back and forth in the cleaning section, and a pair of squeezing rollers 11 squeeze vertically back and forth in the dehydration section and spray dry. This stage lasts for a set time. Stepping stage: After the cleaning stage is completed, all cleaning actuators stop moving, and the main motor 4 drives the wiping belt 3 to advance precisely by one step, so that the ash removal section has been scraped into the cleaning section, the cleaning section has been brushed into the dehydration section, and the dehydrated section has been squeezed into the wiping section for the next wiping of the tin-plating wire. The previously dirty section of the wiping belt enters the ash removal section. After the stepping is completed, the main motor 4 stops and brakes, and the next cleaning stage begins.

[0041] Workflow: Cleaning stage: The auxiliary motor 75 starts, and its output shaft alternates between forward and reverse rotation according to the set cycle. The specific action is broken down as follows: The auxiliary motor 75 drives the drive gear 72 to rotate. Since the drive gear 72 meshes with the rack 73, the entire moving assembly 7, together with the connecting box 74 and the cleaning roller brush 6, moves horizontally along the first slide rail 77. At the same time, the rotation of the drive gear 72 drives the cleaning roller brush 6 to rotate at high speed through the transmission wheel 741 and the transmission belt 742. The high-speed rotating cleaning roller brush 6 performs a comprehensive and repeated scrubbing of the cleaning section of the dust removal strip 3 that is completely immersed in the cleaning liquid during horizontal reciprocating movement, and peels the tin dust particles deeply adsorbed by the towel strip 32 into the cleaning liquid.

[0042] When the moving component 7 moves horizontally, the connecting seat 921 below the scraper rod 10 is pulled by the linkage component 8. Since the adjusting seat 9 can only slide vertically through the limiting component 13, the horizontal pulling force of the linkage component 8 is converted into a vertical traction force. When the moving component 7 moves to the right, the linkage component 8 pushes the scraper rod 10 upward; when the moving component 7 moves to the left, the linkage component 8 pulls the scraper rod 10 downward. In this way, the scraper rod 10 slides continuously vertically back and forth on the outer surface of the dust removal section of the dust removal belt 3. The edge of the long groove of the scraper rod 10 forms a scraping action with the surface of the towel strip 32, scraping off the tin ash softened by the cleaning liquid or floating on the surface of the dust removal belt 3. At the same time, the vacuum pump 102 sucks the scraped tin ash into the vacuum pipe 101 and collects it.

[0043] Similarly, the moving component 7 is connected to the adjusting seat 9 of a pair of squeezing rollers 11 via the linkage component 8. The movement phases of the scraper bar 10 and the squeezing rollers 11 are opposite, that is, one moves upward and the other moves downward. Under the traction of the linkage component 8, the upper and lower squeezing rollers 11 move vertically and reciprocally as a whole along the surface of the dewatering section of the wiping belt 3. Since the gap between the two squeezing rollers 11 is fixed and slightly smaller than the thickness of the wiping belt 3, when they move back and forth, it is equivalent to applying continuous and repeated crushing and wringing effects to the wiping belt 3 sandwiched in the middle, squeezing out the residual liquid after cleaning. At the same time, the air pump 114 continuously supplies air to the inside of the two squeezing rollers 11. High-pressure gas is ejected from the jet hole and blown directly onto the surface of the wiping belt 3, further removing residual moisture and small particles, and achieving rapid fluffing.

[0044] Stepping stage: After pre-scraping by the scraper bar 10, deep cleaning by the cleaning roller brush 6, and squeezing and drying by the wringer roller 11, the towel strips 32 of the wiping belt 3 have been restored to a relatively clean state. At this time, the cleaning action is stopped, the main motor 4 is started, and the main motor 4 drives one of the transmission rollers 2 to rotate at a constant speed. Through the precise meshing of the gear disc 22 and the gear belt 31, the entire wiping belt 3 is driven to move precisely one step in the set direction. The various sections of the wiping belt 3 achieve progressive work station: the section of the ash removal section that has completed scraping moves forward into the cleaning section; the section of the cleaning section that has completed brushing moves forward into the dewatering section; the section of the dewatering section that has completed squeezing and air spraying moves forward into the wiping section; the section of the wiping section that was originally covered with tin ash moves forward into the ash removal section, waiting for the next round of cleaning stage for scraping.

[0045] The cleaning and stepping stages are performed alternately and cyclically. Each section of the wiping belt 3 undergoes a complete regeneration process of wiping, removing dust, washing, removing water, and then re-entering the wiping belt. This avoids the hassle of frequently changing the wiping cloth manually and significantly improves production efficiency.
