Description

Technical Field

[0001] The present invention relates to the technical field of fiber laying machines, and in particular to a layered laying device and a laying method for high-density fiber materials. Background Art

[0002] High-density fiber materials, due to their excellent mechanical properties, lightweight characteristics, and corrosion resistance, are widely used in a variety of industries, including aerospace, automotive manufacturing, wind power generation, shipbuilding, and building reinforcement. These materials are typically used as reinforcing substrates, combined with resins or other binders to form composite structures to enhance the strength, rigidity, and durability of the products. In the production of composite materials, the layered placement process is a key technology. This involves placing fiber tapes layer by layer on a mold or substrate surface in a predetermined direction and sequence using a placement head in a placement machine. Appropriate bonding or compaction is then performed between each layer to form the desired multilayer structure.

[0003] A Chinese patent discloses: a wire laying head and a wire laying machine, patent announcement number: CN114851596A, which "includes a wire laying head bracket, a magnetic powder brake, a prepreg tape mounting disk, a heating mechanism and a pressure mechanism. The magnetic powder brake is fixed to the wire laying head bracket and includes a rotating shaft. The prepreg tape mounting disk is used to wind the prepreg tape and is coaxially fixedly connected to the rotating shaft. The heating mechanism is used to heat the prepreg tape and includes a roller and a heating device fixed to the roller. The roller is rotatably mounted on the wire laying head bracket and is used to roll in contact with the prepreg tape released by the prepreg tape mounting disk."

[0004] The wire laying machine does not rely on a wire feeding motor for wire feeding, but relies on the movement of the fiber itself to drive the movement of the magnetic powder brake, reducing the volume and weight, and is suitable for the laying of small structural parts. However, the existing wire laying head lacks an effective tension adjustment mechanism during the laying process, and tension control is a key factor in ensuring the quality of fiber material laying. If the tension is too large, the fiber may be over-stretched, resulting in a decrease in material performance or even breakage; if the tension is too small, it may cause the fiber to relax, making the laying layer uneven, affecting the overall structural stability of the composite material. Since the equipment cannot accurately adjust the fiber tension according to actual needs, its adaptability to different materials and process requirements is limited, affecting the laying quality and production efficiency. At the same time, during the laying process of fiber materials, dust, oil and impurities may remain on the surface of the board. These pollutants may come from environmental pollution in previous processes such as mechanical processing, storage or transportation. If they are not effectively cleaned, they may affect the adhesion of the fiber, resulting in a decrease in the bonding force between layers, which in turn affects the quality and performance of the final composite material. Summary of the Invention

[0015] A method for laying high-density fiber materials, using the above-mentioned layered laying device for high-density fiber materials, comprises the following steps: S1. Fiber laying belt transmission: The fiber laying belt starts from the winding roller and passes through the outer wall of two driving rollers, flexible roller and adjusting roller in sequence. The laying belt is smoothly transmitted along these rollers to prepare for tension adjustment. S2. Tension adjustment and buffering: When the tension of the laying belt needs to be adjusted, the threaded rod is rotated. The rotation of the threaded rod drives the slide block to slide along the slide rail, and then moves the adjusting roller. At this time, the laying belt is gradually tightened. During the tightening process of the laying belt, the adjusting roller further drives the slider to slide in the slide groove. When the slider moves, the slider applies a squeezing force to the buffer spring, generating a buffering effect; S3. Anti-loosening design: The sliding of the slide block also drives the rack to move, driving the first gear to rotate. The rotation of the first gear drives the rotating rod to rotate. The rotating rod drives the elliptical block to rotate. When the elliptical block rotates, it squeezes the extrusion bumps on both sides. The extrusion bumps drive the centering rod to move outward. The centering plate taps the fiber laying belt through the centering rod. S4. Alcohol spraying: During the laying process, the flexible roller will continue to rotate as the laying belt advances. Its rotation is driven by the belt, driving the second bevel gear to rotate. The rotation of the second bevel gear further drives the first bevel gear to rotate. The rotation of the first bevel gear causes the reciprocating screw to start rotating. The rotation of the reciprocating screw causes the extrusion rod threadedly connected to its outer wall to start reciprocating up and down. When it rises, one end of the extrusion rod applies pressure to the rubber extrusion sheet, causing it to contract inward, thereby increasing the pressure inside the alcohol storage tank. Under the action of the increased pressure, the cleaning liquid in the alcohol storage tank is pushed to the hollow rod and sprayed onto the top of the slab to be laid through the rotating nozzle at its bottom end; S5. Sprinkler rotation: The rotation of the reciprocating screw also drives the second gear, which further drives the third gear to rotate, and then drives the rotating sprinkler to rotate synchronously. At the same time, the extrusion rod continues to reciprocate up and down, achieving intermittent spraying and expanding the spray coverage; S6. Cleaning: After spraying, the reciprocating screw continues to operate, driving the cleaning plate to rotate. A wet sponge is provided at the bottom of the cleaning plate to evenly apply alcohol and clean the dust and oil on the surface. After the cleaning process, the rubber scraper intervenes to scrape off excess alcohol on the surface of the plate. The arc-shaped structure of the rubber scraper ensures that the alcohol is concentrated in the middle area of ​​the plate, which is convenient for subsequent cleaning. The absorbent sponge further absorbs the scraped alcohol and performs secondary cleaning.

[0016] Beneficial effects of the present invention: 1. A layered laying device and method for high-density fiber materials. The tension adjustment mechanism ensures the uniformity and stability of the fiber material during the laying process by precisely adjusting the tension of the fiber laying belt. Specifically, the rotation of the threaded rod drives the slide block to slide on the slide rail, thereby moving the adjustment roller, so that the fiber laying belt is gradually tightened. When the fiber laying belt is tightened, the adjustment roller triggers the slide groove to apply an extrusion force to the buffer spring through the slider, thereby providing a buffering effect. The fiber tension can be precisely adjusted according to actual needs to avoid excessive tension causing the fiber laying belt to break or insufficient tension causing fiber relaxation. The moderate flexible tension can be maintained to make the laying more uniform and avoid affecting the overall structural stability of the composite material.

[0017] 2. A layered laying device and method for high-density fiber materials uses a centering rod and a centering plate to limit the fiber laying belt, keeping it tightly arranged. This mechanism effectively prevents the fiber laying belt from loosening while adjusting its tension, avoiding gap problems caused by loosening during the laying process. In addition, this mechanism ensures that the fiber laying belt is laid along a preset trajectory, thereby improving laying accuracy, ensuring uniform distribution of fiber materials, and enhancing the quality of the final product.

[0018] 3. A layered laying device and laying method for high-density fiber materials. The cleaning mechanism realizes efficient and precise alcohol spraying and surface cleaning through a multi-stage linkage design. First, the reciprocating screw drives the extrusion rod to reciprocate up and down, so that the cleaning liquid in the alcohol storage tank is evenly sprayed onto the surface of the panel to be laid under pressure, and the spray coverage is expanded by rotating the nozzle to avoid waste caused by excessive spraying. Subsequently, the cleaning plate evenly applies alcohol and cleans dust and oil through a wet sponge to ensure a clean surface. The rubber scraper effectively collects and scrapes off excess alcohol, and the absorbent sponge further absorbs the residual liquid for secondary cleaning to improve the overall cleanliness. The mechanism ensures that the surface of the panel is dust-free and oil-free through the coordination of multiple links such as spraying, cleaning, scraping, and absorption. It can effectively improve the fit between the fiber laying belt and the panel, prevent dust and oil from affecting the adhesion effect, and make the fiber laying belt adhere more firmly and evenly to the surface of the panel.

[0024] like Figures 1 to 7As shown, a layered laying device for high-density fiber materials includes a laying machine body 1, the interior of the laying machine body 1 is fixedly connected to a fixing frame 2 for fixing a plate, the output end of the laying machine body 1 is provided with a laying head shell 4, the inner wall of the laying head shell 4 is rotatably connected to a winding roller 5, the inner wall of the laying head shell 4 is rotatably connected to two transmission rollers 6, the outer wall of the laying head shell 4 is fixedly connected to a servo motor 7, the output end of the servo motor 7 passes through the inner wall of the laying head shell 4 and is fixedly connected to a flexible roller 8, the flexible roller 8 is rotatably connected to the inner wall of the laying head shell 4, the interior of the laying head shell 4 is provided with a tension adjustment mechanism for adjusting the tension of the fiber material, and the bottom of the inner wall of the laying head shell 4 is provided with a cleaning mechanism for cleaning the plate fixed on the top of the fixing frame 2.

[0025] For further information, see the attached Figures 2 to 5 As shown, the tension adjustment mechanism includes a slide rail 9 fixedly connected to the inner wall of the wire laying head shell 4, the outer wall of the slide rail 9 is slidably connected to a slide rail block 10, the inner wall of the wire laying head shell 4 is rotatably connected to a threaded rod 12 near the middle part of the slide rail 9, the slide rail block 10 is threadedly connected to the outer wall of the threaded rod 12, one end of the threaded rod 12 passes through the outer wall of the wire laying head shell 4 and is fixedly connected to the turntable 3, a slide groove 13 is provided on the side wall of the slide rail block 10, the inside of the slide groove 13 is slidably connected to a slider 41, the side wall of the slider 41 is rotatably connected to an adjusting roller 11, the inner wall of the slide groove 13 is fixedly connected to a buffer spring 14, one end of the buffer spring 14 is fixedly connected to the side wall of the slider 41, and the top of the slide rail block 10 is fixedly connected to a rack 15. One end of the rack 15 passes through the outer wall of the wire placing head shell 4, and the inner wall of the wire placing head shell 4 is fixedly connected to a support column 16, and two groups of centering rods 17 are fixedly connected to both sides of the outer wall of the support column 16, and a centering plate 18 is fixedly connected between one end of the two groups of centering rods 17. The inner wall of the centering rod 17 is fixedly connected to an extrusion protrusion 19, and the top of the inner wall of the wire placing head shell 4 is rotatably connected to a rotating rod 20, and both ends of the outer wall of the rotating rod 20 are fixedly connected to an elliptical block 21, and the outer walls of the elliptical block 21 are in contact with the extrusion protrusion 19 respectively. The top outer wall of the rotating rod 20 is fixedly connected to a first gear 22, and the rack 15 and the outer walls of the first gear 22 are meshed with each other. A compression spring 23 is fixedly connected between the opposite surfaces of the two groups of centering rods 17; During the use of the tension adjustment mechanism, first, the fiber laying belt wound in the winding roller 5 is passed around the two transmission rollers 6, the flexible roller 8 and the outer wall of the adjusting roller 11 in sequence. When the tension of the fiber laying belt needs to be adjusted, the threaded rod 12 is rotated, and the threaded rod 12 drives the slide block 10 to slide on the outer wall of the slide rail 9. While the slide block 10 slides, it drives the adjusting roller 11 on the side wall to move, so that the fiber laying belt is gradually tightened. When the fiber laying belt is tightened, the adjusting roller 11 will further drive the slider 41 to slide in the slide groove 13. After the slider 41 is restricted, the slide groove 13 will apply an extrusion force to the buffer spring 14, thereby providing a buffering effect to prevent the adjusting roller 11 from applying excessive tension and prevent the fiber laying belt from breaking due to excessive force. To ensure that the fiber material can still maintain moderate flexible tension in the tensioned state, the tension adjustment mechanism ensures the uniformity and stability of the fiber material during the laying process by accurately adjusting the tension of the fiber laying belt. Specifically, the rotation of the threaded rod 12 drives the slide block 10 to slide on the slide rail 9, thereby moving the adjustment roller 11, so that the fiber laying belt is gradually tightened. When the fiber laying belt is tightened, the adjustment roller 11 triggers the slide groove 13 to apply an extrusion force to the buffer spring 14 through the slider 41, thereby providing a buffering effect. The fiber tension can be accurately adjusted according to actual needs to avoid excessive tension causing the fiber laying belt to break or too little tension causing the fiber to relax. It can maintain moderate flexible tension, make the laying more uniform, and avoid affecting the overall structural stability of the composite material. In addition, during the process of adjusting the tension of the fiber laying belt, the slide block 10 will also drive the rack 15 to move and drive the first gear 22 to rotate. When the first gear 22 rotates, it will further drive the rotating rod 20 to rotate, and the rotation of the rotating rod 20 will drive the elliptical blocks 21 at both ends to rotate. When the elliptical block 21 rotates to a specific position, it squeezes the extrusion protrusions 19 on both sides, so that the extrusion protrusions 19 drive the centering rod 17 to rotate after being subjected to force, so that one end of the centering rod 17 moves away from each other, and drives the compression spring 23 to stretch. As the elliptical block 21 continues to rotate and leaves the extrusion position, the compression spring 23 drives the extrusion protrusion 19 to return to its original position under the action of the rebound force. The centering rods 17 on both sides drive the centering plate 18 to tap the two sides of the fiber laying belt to ensure that the fiber laying belt always remains tightly arranged. The design of this mechanism can effectively prevent the fiber laying belt from loosening while adjusting the tension of the fiber laying belt, avoiding gap problems caused by loosening during the laying process. In addition, this mechanism can also ensure that the fiber laying belt is laid along the preset trajectory, thereby improving the laying accuracy, ensuring the uniform distribution of the fiber material, and improving the quality of the final product.

[0026] For further information, see the attached Figures 6 and 7As shown, the cleaning mechanism includes an alcohol storage tank 24, which is fixedly connected to the inner wall of the wire laying head shell 4, and a support plate 25 is fixedly connected to the inner wall of the wire laying head shell 4 near the bottom of the alcohol storage tank 24. A reciprocating screw rod 26 is rotatably connected between the bottom of the alcohol storage tank 24 and the top of the support plate 25, and a first bevel gear 27 is fixedly connected to the bottom outer wall of the reciprocating screw rod 26. The outer wall of the first bevel gear 27 is meshed with a second bevel gear 28, and the shaft of the second bevel gear 28 is rotatably connected to the inner wall of the wire laying head shell 4. A belt 29 is provided between the shaft of the flexible roller 8 and the shaft of the second bevel gear 28 through a pulley sleeve, and an extrusion rod 30 is threadedly connected to the outer wall of the reciprocating screw rod 26. A rubber extrusion sheet 31 is fixedly connected to the bottom of the alcohol storage tank 24. When the extrusion rod 30 moves upward, the arc structure at one end of the extrusion rod 30 squeezes the rubber extrusion sheet 3 The outer wall of the bottom end of the reciprocating screw rod 26 is fixedly connected to the second gear 34, and the outer wall of the rotating nozzle 33 is fixedly connected to the third gear 35. The second gear 34 and the third gear 35 are meshed with each other. The bottom end of the reciprocating screw rod 26 penetrates the support plate 25 and is fixedly connected to the cleaning plate 36. The shape of the cleaning plate 36 is cross-shaped, and the bottom of the cleaning plate 36 is fixedly connected to a wet sponge. The bottom of the support plate 25 near the flexible roller 8 is fixedly connected to a rubber wiper 37. The shape of the rubber wiper 37 is arc-shaped, and the inner wall of the rubber wiper 37 is fixedly connected to a water-absorbing sponge 38. During operation, the flexible roller 8 presses and lays the fiber laying belt while rotating continuously as the laying progresses. As the flexible roller 8 rotates, the belt 29 drives the second bevel gear 28 to rotate synchronously, which in turn drives the first bevel gear 27 to rotate, causing the reciprocating screw 26 to begin operating. As the reciprocating screw 26 rotates, it drives the extrusion rod 30, which is threaded onto its outer wall, to reciprocate up and down. The extrusion rod 30 is L-shaped. As it rises, one end of the extrusion rod 30 applies pressure to the rubber extrusion sheet 31, causing it to contract inward, thereby increasing the pressure inside the alcohol storage tank 24. Under this pressure, the cleaning liquid in the alcohol storage tank 24 is pushed into the hollow rod 32 and sprayed through the rotating nozzle 33 at its bottom. Because the spray aperture of the rotating nozzle 33 is small, the alcohol does not leak when not spraying. However, when the pressure inside the storage tank increases, the alcohol is evenly sprayed onto the top of the panel to be laid. At the same time, the rotation of the reciprocating screw 26 also drives the second gear 34, which in turn drives the third gear 35 to rotate, so that the rotary nozzle 33 rotates synchronously during the spraying process. At the same time, the extrusion rod 30 performs up and down reciprocating motion to achieve intermittent spraying. This design not only effectively expands the spray coverage area, but also avoids the waste caused by excessive spraying of alcohol. After spraying is completed, the reciprocating screw 26 further drives the cleaning plate 36 to rotate. A wet sponge is provided at the bottom of the cleaning plate 36 to evenly apply the sprayed alcohol and clean the dust and oil on the surface of the plate to ensure the surface is clean. After cleaning is completed, the alcohol will evaporate and the rubber scraper 37 will intervene to scrape off the excess alcohol on the surface of the plate. Due to the curved design of the rubber scraper 37, the scraped alcohol will be gathered in the middle area of ​​the rubber scraper 37, which is convenient for subsequent cleaning. Finally, the absorbent sponge 38 further absorbs the scraped alcohol and performs a second cleaning on the surface of the panel to improve the overall cleanliness and ensure that the surface of the panel is free of dust and oil. Through this fine cleaning process, the fit between the fiber laying tape and the panel can be effectively improved, preventing dust and oil from affecting the adhesion effect, making the fiber laying tape more firmly and evenly adhered to the surface of the panel, and improving the quality and stability of the final product.

[0027] For further information, see the attached Figure 7 As shown, a heating lamp 39 for heating the fiber material during laying is fixedly connected to one end of the support plate 25 close to the flexible roller 8. The heating lamp 39 is activated to heat the side of the fiber laying belt close to the board, so that the fiber laying belt is softened and can be better fixed on the board.

[0028] For further information, see the attached Figure 6 As shown, the end of the extrusion rod 30 away from the reciprocating screw rod 26 is in an arc shape. When the extrusion rod 30 moves upward, the arc at one end of the extrusion rod 30 squeezes the rubber extrusion sheet 31. By making one end of the extrusion rod 30 arc-shaped, the pressing area is increased, while avoiding the extrusion force being concentrated in the middle part of the rubber extrusion sheet 31.

[0029] For further information, see the attached Figure 7 As shown, the top of the alcohol storage tank 24 is connected to a flow pipe 40, and a one-way valve is provided inside the flow pipe 40. When one end of the extrusion rod 30 presses the rubber extrusion sheet 31 through the one-way valve, the one-way valve is in a closed state. When the rubber extrusion sheet 31 returns to its original state, the alcohol storage tank 24 is in a negative pressure state, and the flow pipe 40 will open, allowing air to enter the alcohol storage tank 24.

[0030] The present application also provides a method for laying a high-density fiber material, using the above-mentioned layered laying device for high-density fiber material, comprising the following steps: S1. Fiber laying belt transmission: The fiber laying belt starts from the winding roller 5, passes through the outer wall of the two driving rollers 6, the flexible roller 8 and the adjusting roller 11 in sequence, and the laying belt is smoothly transmitted along these rollers to prepare for tension adjustment; S2. Tension adjustment and buffering: When the tension of the laying belt needs to be adjusted, the threaded rod 12 is rotated. The rotation of the threaded rod 12 drives the slide block 10 to slide along the slide rail 9, and then moves the adjusting roller 11. At this time, the laying belt is gradually tightened. During the tightening process of the laying belt, the adjusting roller 11 further drives the slider 41 to slide in the slide groove 13. When the slider 41 moves, the slider 41 applies an extrusion force to the buffer spring 14, generating a buffering effect. The fiber tension can be accurately adjusted according to actual needs to avoid excessive tension causing the fiber laying belt to break or too little tension causing the fiber to relax. S3. Anti-loosening design: The sliding of the slide block 10 also drives the rack 15 to move, driving the first gear 22 to rotate. The rotation of the first gear 22 drives the rotating rod 20 to rotate. The rotating rod 20 drives the elliptical block 21 to rotate. When the elliptical block 21 rotates, it squeezes the extrusion protrusions 19 on both sides. The extrusion protrusions 19 drive the centering rod 17 to move outward. The centering plate 18 taps the fiber laying belt through the centering rod 17 to ensure that the laying belt always maintains a stable position during the transmission process, prevents loosening, avoids the unevenness of the laying belt, and thus improves the laying effect; S4. Alcohol spraying: During the laying process, the flexible roller 8 will continue to rotate as the laying belt advances. Its rotation is transmitted through the belt 29, driving the second bevel gear 28 to rotate. The rotation of the second bevel gear 28 further drives the first bevel gear 27 to rotate. The rotation of the first bevel gear 27 causes the reciprocating screw 26 to start rotating. The rotation of the reciprocating screw 26 causes the extrusion rod 30 threadedly connected to its outer wall to start reciprocating up and down. When it rises, one end of the extrusion rod 30 applies pressure to the rubber extrusion sheet 31, causing it to shrink inward, thereby increasing the pressure inside the alcohol storage tank 24. Under the action of the increased pressure, the cleaning liquid in the alcohol storage tank 24 is pushed to the hollow rod 32 and sprayed to the top of the board to be laid through the rotating nozzle 33 at its bottom end. This process effectively controls the amount of alcohol spraying, avoids waste, and at the same time increases the uniformity of spraying, which helps to keep the board clean; S5. Spray head rotation: The rotation of the reciprocating screw 26 also drives the second gear 34, which further drives the third gear 35 to rotate, and then drives the rotating spray head 33 to rotate synchronously. At the same time, the extrusion rod 30 continues to reciprocate up and down, realizing intermittent spraying, expanding the spraying coverage, optimizing the spraying accuracy and uniformity, effectively improving the spraying effect, and reducing alcohol waste; S6. Cleaning: After spraying is completed, the reciprocating screw 26 continues to operate, driving the cleaning plate 36 to rotate. A wet sponge is provided at the bottom of the cleaning plate 36 to evenly apply alcohol and clean the dust and oil on the surface. After the cleaning process, the rubber scraper 37 intervenes to scrape off excess alcohol on the surface of the plate. The arc-shaped design of the rubber scraper 37 ensures that the alcohol is concentrated in the middle area of ​​the plate, which is convenient for subsequent cleaning. The absorbent sponge 38 further absorbs the scraped alcohol and performs secondary cleaning to improve the overall cleanliness, ensure that the surface of the plate is free of dust and oil, and make the fiber laying belt more firmly and evenly adhere to the surface of the plate.

[0031] Through the above method, the entire adjustment process ensures the uniformity and stability of the fiber material during the laying process. The fiber tension can be accurately adjusted according to actual needs to avoid excessive tension causing the fiber laying belt to break or too little tension causing the fiber to relax. It can maintain moderate flexible tension to make the laying more uniform. At the same time, the alcohol spraying and cleaning function not only ensures that the dust and oil on the surface of the panel are completely removed to avoid affecting the laying quality, but also reduces waste, enhances the cleaning effect, and improves the overall cleanliness through intermittent spraying and precise control of the use of alcohol, thereby ensuring the stability and quality of the final product.

10. A method for laying high-density fiber materials, using a layered laying device for high-density fiber materials according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Fiber laying belt transmission: The fiber laying belt starts from the winding roller (5), and passes through the outer wall of two transmission rollers (6), the flexible roller (8) and the adjusting roller (11) in sequence. The laying belt is smoothly transmitted along these rollers to prepare for tension adjustment; S2. Adjusting the tension and buffering: When the tension of the laying belt needs to be adjusted, the threaded rod (12) is rotated. The rotation of the threaded rod (12) drives the slide block (10) to slide along the slide rail (9), thereby moving the adjusting roller (11). At this time, the laying belt is gradually tightened. During the process of tightening the laying belt, the adjusting roller (11) further drives the slider (41) to slide in the slide groove (13). When the slider (41) moves, the slider (41) applies a squeezing force to the buffer spring (14), thereby generating a buffering effect. S3. Anti-loosening design: The sliding of the slide block (10) also drives the rack (15) to move, driving the first gear (22) to rotate. The rotation of the first gear (22) drives the rotating rod (20) to rotate. The rotating rod (20) drives the elliptical block (21) to rotate. When the elliptical block (21) rotates, it squeezes the extrusion protrusions (19) on both sides. The extrusion protrusions (19) drive the centering rod (17) to move outward. The centering plate (18) taps the fiber laying belt through the centering rod (17); S4. Alcohol spraying: During the laying process, the flexible roller (8) will continue to rotate as the laying belt advances. Its rotation is transmitted through the belt (29), driving the second bevel gear (28) to rotate. The rotation of the second bevel gear (28) further drives the first bevel gear (27) to rotate. The rotation of the first bevel gear (27) causes the reciprocating screw (26) to start rotating. The rotation of the reciprocating screw (26) causes the extrusion rod (30) connected to its outer wall thread to start reciprocating up and down. When it rises, one end of the extrusion rod applies pressure to the rubber extrusion sheet (31), causing it to shrink inward, thereby increasing the pressure inside the alcohol storage tank (24). Under the action of the increased pressure, the cleaning liquid in the alcohol storage tank (24) is pushed to the hollow rod (32) and sprayed to the top of the plate to be laid through the rotating nozzle (33) at its bottom end; S5, nozzle rotation: The rotation of the reciprocating screw (26) also drives the second gear (34), which further drives the third gear (35) to rotate, thereby driving the rotating nozzle (33) to rotate synchronously. At the same time, the extrusion rod (30) continues to reciprocate up and down, achieving intermittent spraying and expanding the spraying coverage; S6. Cleaning: After the spraying is completed, the reciprocating screw (26) continues to operate, driving the cleaning plate (36) to rotate. A wet sponge is provided at the bottom of the cleaning plate (36), which is evenly coated with alcohol and cleans the dust and oil on the surface. After the cleaning process, the rubber scraper (37) intervenes to scrape off the excess alcohol on the surface of the plate. The arc structure of the rubber scraper (37) ensures that the alcohol is concentrated in the middle area of ​​the plate. The absorbent sponge (38) further absorbs the scraped alcohol and performs a second cleaning.
