Description

Technical Field

[0001] This invention belongs to the field of conveying device technology, and specifically discloses a conveying device and method for processing aluminum alloy plates. Background Technology

[0002] In the deep processing production line of aluminum alloy sheets, corrugated aluminum alloy sheets are widely used in the manufacturing of building curtain walls, rail transit and special vehicle carriage floor panels due to their high structural strength and excellent lightweight characteristics. After being stamped or rolled, these sheets typically undergo a continuous process of cleaning and degreasing, passivation, drying and curing, and surface coating.

[0003] Currently, for the inter-plate transfer and station connection of the aforementioned corrugated aluminum alloy sheets, the industry generally uses roller conveyors as the basic conveying device, mainly responsible for the directional transfer of the sheets along a straight line from the cleaning station to the subsequent drying station. However, because the cross-section of the corrugated aluminum alloy sheet has continuous concave and convex peaks and troughs, a large amount of residual process water after the cleaning process will accumulate in the troughs due to surface tension and cannot flow out naturally. When the sheet moves forward on the conveyor, the water stains accumulated in the grooves move synchronously with the sheet, resulting in unstable contact between the sheet surface and the conveyor roller surface. During the transmission of the conveying driving force, it is very easy to cause irregular lateral displacement of the corrugated sheet in the width direction. This not only reduces the positioning accuracy of the conveyor, but also causes the sheet to scrape against the side wall of the drying tunnel entrance when it enters the downstream drying station due to the skewed position, causing mechanical damage to the corrugated peaks and resulting in a high scrap rate. Furthermore, when corrugated boards carrying a large amount of accumulated liquid in the grooves enter the subsequent high-temperature drying station, the droplets vaporize instantly at high temperatures, which not only consumes additional heat energy, but also causes the residual solutes in the water to form stubborn water stains on the surface of the board, affecting the surface quality of the product.

[0004] In summary, existing corrugated aluminum alloy sheet conveying devices lack online processing capabilities for water accumulation in the grooves of the corrugated irregular cross-section, making it difficult to solve the offset problem caused by water stains on the sheet surface while ensuring stable conveying. Therefore, it is necessary to develop a new type of conveying device for corrugated aluminum alloy sheets that can efficiently remove water accumulation in the grooves by changing the conveying posture of the sheet or by utilizing the mechanical action of the conveying structure during the conveying process, thereby eliminating conveying offset caused by water stains, improving conveying positioning accuracy and the smoothness of connection with downstream processes. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art where corrugated aluminum alloy plates experience lateral displacement during transport due to water accumulation in the grooves, affecting transport positioning accuracy and the smoothness of downstream process connections. Therefore, this invention proposes a transport device for aluminum alloy plate processing, comprising a conveyor, a centering mechanism, and a plate body. The centering mechanism is located at the feeding end of the conveyor. The plate body is placed above the conveyor. A plate feeding mechanism is located on one side of the conveyor, and a cross-frame is located outside the plate feeding mechanism. Driven by the plate feeding mechanism, the cross-frame can move horizontally above the conveyor. The cross-frame moves back and forth. A frame base is fixedly installed on the outside of one side of the cross-frame and near the middle. Telescopic components are provided on both sides of the inside of the cross-frame. The telescopic end of the telescopic component is connected to a sliding seat. The upper end of the sliding seat slides into the inside of the frame base. A front probe plate is fixedly connected to one side of the sliding seat. Movable plates are correspondingly connected to both sides of the sliding seat through a first hydraulic cylinder. Multiple wheels are installed on the upper surface of the front probe plate and the movable plate. The multiple wheels are used to pass through the corrugated groove of the plate body and lift up the side that is in contact with the upper surface of the conveyor. An air intake mechanism is provided at the lower ends of both sides of the sliding seat. One end of the air intake mechanism is connected to a water blowing mechanism, which includes two water blowing pipes connected by a double-through rigid pipe. A stabilizing mechanism is provided on the outside of the double-through rigid pipe. The two water blowing pipes are arranged symmetrically at the top and bottom, and nozzles are installed at equal intervals along the horizontal direction inside the two water blowing pipes. The nozzle at the upper water blowing pipe sprays out diagonally downward to one side, and the nozzle at the lower water blowing pipe sprays out diagonally upward to one side.

[0006] In the above scheme, the centering mechanism further includes two sets of cylinders, which are fixedly installed on both sides of the conveyor and close to the feeding point. The telescopic ends of the two sets of cylinders are fixedly connected to centering push plates. The two sets of centering push plates are used to clamp the plate body so that the plate body is centered and sent into the rear end of the conveyor.

[0007] In the above scheme, the feeding mechanism further includes a lifting platform, one side of which is fixedly connected to one side of the conveyor. A second hydraulic cylinder is fixedly installed inside the lifting platform. A snap-fit ​​plate is fixedly connected to the telescopic end of the second hydraulic cylinder. A frame is fixedly connected to one side of the snap-fit ​​plate. The frame is fixedly connected to the cross frame. Guide rods are symmetrically installed on the outside of the snap-fit ​​plate. The ends of the two guide rods away from the snap-fit ​​plate are inserted at the rear end of the lifting platform.

[0008] In the above scheme, furthermore, columns are symmetrically installed on both sides of the conveyor, and a sliding rod is inserted between the two sets of columns on the same side. The cross frame is slidably sleeved on the outside of the two sliding rods.

[0009] In the above scheme, the telescopic assembly further includes two sets of electric push cylinders, which are respectively fixedly installed on both sides inside the cross frame, and the telescopic ends of the two sets of electric push cylinders are fixedly connected to the upper surfaces of both sides of the sliding seat.

[0010] In the above scheme, the air intake mechanism further includes an air pump, which is fixedly installed below one side of the sliding seat, and a booster valve is connected to one side of the air pump. A delivery pipe is connected to the lower end of the booster valve, and one end of the delivery pipe is connected to the interior of the water blowing pipe below. A retainer is fixedly installed on the exterior of both ends of the front probe plate near the water blowing pipe.

[0011] In the above scheme, a mounting bracket is further fixedly installed on the front end of the sliding seat, and a visual contour scanner is fixedly installed on the front end of the mounting bracket.

[0012] In the above scheme, the stabilizing mechanism further includes a slide plate, one end of which is fixedly sleeved on the outside of the double-through rigid tube. A retaining frame is vertically connected to the upper surface of the slide plate. A pressure rod is slidably installed inside the retaining frame. A spring is fitted outside the pressure rod and inside the retaining frame. A retaining plate is fixedly installed at the lower end of the pressure rod. Stabilizing wheels are installed at both ends of the lower part of the retaining plate. The two sets of stabilizing wheels are tactilely connected to the upper surface of the conveyor. The upper part of the retaining plate slides through the top of the slide plate.

[0013] A conveying method for processing aluminum alloy sheets, based on the aforementioned conveying device for processing aluminum alloy sheets, includes the following steps: S1: Place the plate at the feed end of the conveyor, start the centering mechanism to center the plate, and then transport the centered plate along the upper surface of the conveyor in the discharge direction. S2: Activate the telescopic assembly inside the cross frame, so that the telescopic end of the telescopic assembly pushes the sliding seat to move until the front probe plate fixedly connected to one side of the sliding seat and the multiple wheels on the movable plate connected by the first hydraulic cylinder are respectively inserted into the corrugated groove of the plate. S3: Keep the wheels inserted into the corrugated groove, start the first hydraulic cylinders on both sides of the sliding seat, drive the movable plate to move relative to the front probe plate, so that the wheels lift one side of the plate away from the upper surface of the conveyor in the corrugated groove. S4: Maintain the state where one side of the plate is lifted, drive the plate feeding mechanism again, so that the cross frame drives the sliding seat and the lifted plate to move horizontally in the conveying direction, so as to realize the forward conveying of the plate. One end of the plate is in contact with the upper surface of the conveyor. At this time, the plate is in an inclined state, and the conveyor stops conveying. S5: Then, water is blown at both the top and bottom ends of the plate. During the horizontal movement and conveying of the plate across the frame, the air intake mechanism at the lower ends of both sides of the sliding seat is activated, so that high-pressure gas enters the two water blowing pipes of the water blowing mechanism through the air intake mechanism. The nozzle of the upper water blowing pipe sprays the upper surface of the plate diagonally downward, while the nozzle of the lower water blowing pipe sprays the lower surface of the plate diagonally upward, in order to remove the residual processing fluid or moisture on the surface of the plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention, by setting up wheels that can extend into the corrugated grooves, can lift one side of the plate away from the conveyor surface during the conveying process, putting the plate in an inclined state. This inclined posture breaks the horizontal stability condition of the water accumulated in the trough grooves, causing the residual liquid to converge and flow to lower places under the action of gravity, thereby reducing the adhesion of the water in the grooves and providing a favorable drainage posture for the subsequent water blowing process, effectively improving the conveying deviation problem caused by water accumulation in the grooves.

[0015] This invention, in conjunction with a symmetrically arranged air-blowing mechanism, simultaneously applies high-pressure air to the upper and lower surfaces of the corrugated board during its inclined transport. The upper nozzles spray downwards onto the upper surface of the board, while the lower nozzles spray upwards onto the lower surface. This staggered airflow direction covers the entire concave and convex cross-section of the corrugated board. In particular, it effectively shears and drives away residual processing fluid and moisture inside the grooves, forcibly blowing away droplets accumulated at the bottom of the grooves from the board surface. This allows for simultaneous surface drying during transport, preventing residual liquid from vaporizing at high temperatures and forming water stains after entering the downstream drying station. This ensures the product's appearance quality and the adhesion of subsequent coating processes.

[0016] After the board is dried with water, the feeding mechanism reverses its movement to smoothly remove the crossbeam and wheels from the corrugated grooves of the board, allowing the board to fall accurately onto the conveyor surface. Then, an electric push cylinder raises the sliding seat, completely disengaging the wheels from the board. The conveyor restarts, continuing to transport the board to the downstream station. The entire process is tightly integrated and highly automated, ensuring both the thoroughness of the drying process and the smooth reset and continued transport of the board after drying. This eliminates the risk of wheels jamming or scratching the board, significantly improving conveyor positioning accuracy and production line efficiency. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-7The diagram illustrates a conveying device for processing aluminum alloy plates, comprising a conveyor 1, a centering mechanism, and a plate 4. The centering mechanism is located at the feeding end of the conveyor 1. The conveyor 1 is a roller conveyor, consisting of a drive motor, a reducer, a transmission chain, and multiple parallel conveying rollers. The two ends of the conveying rollers are rotatably mounted on both sides of the frame of the conveyor 1 via bearing seats. The output end of the drive motor, after being reduced in speed and torque by the reducer, is connected to the sprockets at the ends of each conveying roller via the transmission chain, thereby driving each conveying roller to rotate synchronously, realizing the directional movement of the plate 4 on the upper surface of the conveyor 1 along the conveying direction. A plate 4 is placed above the conveyor 1. A plate feeding mechanism is provided on one side of the conveyor 1. A cross frame 5 is provided outside the plate feeding mechanism. Driven by the plate feeding mechanism, the cross frame 5 can move back and forth horizontally above the conveyor 1. A frame base 11 is fixedly installed on the outside of one side of the cross frame 5 and near the middle. Telescopic components are provided on both sides inside the cross frame 5. The telescopic end of the telescopic component is connected to a sliding seat 14. The upper end of the sliding seat 14 slides into the inside of the frame base 11. A front probe plate 12 is fixedly connected to one side of the sliding seat 14. Movable plates 13 are correspondingly connected to both sides of the sliding seat 14 through a first hydraulic cylinder 16. Multiple wheels 19 are installed on the upper surface of the front probe plate 12 and the movable plate 13. The multiple wheels 19 are used to pass through the corrugated groove of the plate 4. The wheels 19 are unpowered driven wheels. Their axles are fixedly installed on the upper surface of the front probe plate 12 and the movable plate 13 through bearing seats. The outer diameter of the wheel 19 should be smaller than the width of the corrugated groove of the plate 4 so that the wheel 19 can be smoothly inserted into the corrugated groove. The wheel body of the wheel 19 can be made of polyurethane or nylon to provide appropriate friction when in contact with the inner wall of the trough of the plate 4, while avoiding scratching the surface of the plate 4; Lift up one side of the upper surface of the conveyor 1. After the wheel 19 is inserted into the corrugated groove of the plate 4, the first hydraulic cylinder 16 drives the movable plate 13 to move upward. The wheel 19 on the movable plate 13 pushes the inner wall of the trough of the plate 4 obliquely upward in the corrugated groove, thereby lifting the side of the plate 4 close to the movable plate 13 away from the upper surface of the conveyor 1. Air intake mechanisms are provided at the lower ends of both sides of the sliding seat 14. One end of the air intake mechanism is connected to a water blowing mechanism. The water blowing mechanism includes two water blowing pipes 17, which are connected by a double-through rigid pipe 22. The double-through rigid pipe 22 is a rigid metal pipe, and its two ends are fixedly connected to the ends of the two water blowing pipes 17 by threaded connection or flange connection, thereby forming a gas flow channel between the two water blowing pipes 17. A stabilizing mechanism is provided on the outside of the double-through rigid pipe 22. The two water blowing pipes 17 are arranged symmetrically at the top and bottom, and nozzles 28 are installed at equal distances along the horizontal direction inside the two water blowing pipes 17. The nozzles 28 at the upper water blowing pipe 17 spray out diagonally downward to one side, and the nozzles 28 at the lower water blowing pipe 17 spray out diagonally upward to one side. The spray directions of the upper and lower rows of nozzles 28 are staggered, so that the high-pressure gas can simultaneously cover the upper and lower surfaces of the plate 4 and the inside of the corrugated groove.

[0022] The centering mechanism includes two sets of cylinders 7, which are fixedly installed on both sides of the conveyor 1 and close to the feeding point. The telescopic ends of the two sets of cylinders 7 are fixedly connected to centering push plates 8. The centering push plates 8 are vertically arranged rectangular plate-shaped components. The two sets of centering push plates 8 are used to clamp the plate body 4 and center the plate body 4 to send it into the rear end of the conveyor 1.

[0023] The feeding mechanism includes a lifting platform 9, one side of which is fixedly connected to the side of the conveyor 1. A second hydraulic cylinder 21 is fixedly installed inside the lifting platform 9. A clamping plate 20 is fixedly connected to the telescopic end of the second hydraulic cylinder 21. A frame 2 is fixedly connected to one side of the clamping plate 20. The frame 2 is fixedly connected to the cross frame 5. Guide rods are symmetrically installed on the outside of the clamping plate 20. The ends of the two guide rods away from the clamping plate 20 are inserted into the rear end of the lifting platform 9. The two guide rods are metal rods with circular cross sections. Their front ends are fixedly connected to the outer wall of the clamping plate 20. Their rear ends extend backward and pass through two guide sleeves fixedly installed at the rear end of the lifting platform 9, thereby providing guidance and support for the movement of the clamping plate 20 and ensuring that the clamping plate 20 and the frame 2 move stably in a straight line under the drive of the second hydraulic cylinder 21 without deflection.

[0024] The conveyor 1 is symmetrically equipped with columns 3 on both sides. The two sets of columns 3 on the same side are connected by sliding rods 6. The cross frame 5 is slidably sleeved on the outside of the two sliding rods 6. That is, the upper ends of the columns 3 on both sides of the cross frame 5 are respectively provided with guide holes for the sliding rods 6 to pass through. The cross frame 5 is slidably sleeved on the outside of the two sliding rods 6 through the guide holes and can slide back and forth along the axis of the sliding rods 6.

[0025] In the above scheme, the telescopic assembly further includes two sets of electric push cylinders 15. The two sets of electric push cylinders 15 are fixedly installed on both sides inside the cross frame 5. The telescopic ends of the two sets of electric push cylinders 15 are fixedly connected to the upper end faces of both sides of the sliding seat 14. The electric push cylinders 15 can drive the sliding seat 14 to telescopically move in the vertical direction. The upper end of the sliding seat 14 can extend into the frame 11.

[0026] The air intake mechanism includes an air pump 10, which is fixedly installed below one side of the sliding seat 14. A booster valve 31 is installed inside the air pump 10. The booster valve 31 is a pneumatic booster valve, whose air inlet is connected to the air outlet of the air pump 10. It is used to boost the compressed air output by the air pump 10 for a second time to increase the pressure of the blown gas. The lower end of the booster valve 31 is connected to a delivery pipe 29. One end of the delivery pipe 29 is connected to the interior of the lower water blowing pipe 17. The delivery pipe 29 is a metal pipe, one end of which is connected to the air outlet of the booster valve 31, and the other end is connected to the interior of the lower water blowing pipe 17, thereby delivering the boosted high-pressure gas to the water blowing pipe 17. On one side of the front probe plate 12 and near both ends of the water blowing pipe 17, a clamping seat 18 is fixedly installed. The clamping seat 18 is an arc-shaped clamping part, and its inner contour is adapted to the outer contour of the water blowing pipe 17. The clamping seat 18 is fixedly installed on the side wall of the front probe plate 12 by bolts, which is used to provide auxiliary support for both ends of the water blowing pipe 17 and prevent the water blowing pipe 17 from shaking or vibrating due to the gas reaction force during the blowing process.

[0027] It should be noted that sealing gaskets or sealing tape should be installed at the connection points between the delivery pipe 29, the booster valve 31, and the water blowing pipe 17 to ensure airtightness and prevent high-pressure gas leakage. An air filter should be installed at the air inlet of the air pump 10 to filter dust and impurities from the intake air, preventing impurities from entering the water blowing pipe 17 and nozzle 28 and causing blockage. The booster valve 31 should be selected according to the actual blowing pressure requirements.

[0028] A mounting bracket 32 ​​is fixedly installed on the front end of the sliding base 14, and a visual contour scanner 30 is fixedly installed on the front end of the mounting bracket 32.

[0029] The mounting bracket 32 ​​is a U-shaped support, one end of which is fixed to the front outer wall of the sliding seat 14 by bolts, and the other end extends horizontally forward. The visual contour scanner 30 is a laser contour scanner or a structured light 3D scanner, which consists of a laser emitter, an image sensor, and a signal processing circuit. The laser emitter of the visual contour scanner 30 emits laser lines or structured light patterns onto the surface of the plate 4. The image sensor receives the laser lines or structured light patterns reflected from the surface of the plate 4, and the signal processing circuit calculates the surface contour data of the plate 4 based on the received light signal. The visual contour scanner 30 communicates with the PLC controller or host computer via a data cable and is used to scan and identify the position of the corrugated groove of the plate 4 before the caster 19 is inserted into the corrugated groove.

[0030] It should be noted that the scanning direction of the visual contour scanner 30 should be perpendicular to the conveying direction of the plate 4, that is, scanning along the width direction of the conveyor 1, in order to obtain the distribution data of the corrugated groove position of the plate 4 in the width direction. According to the corrugated groove position data fed back by the visual contour scanner 30, the PLC controller controls the telescopic component to adjust the lifting position of the sliding seat 14, so that the wheel 19 can be accurately aligned and inserted into the corrugated groove of the plate 4, avoiding misalignment between the wheel 19 and the corrugated groove, which would prevent insertion or scratch the crest of the plate 4.

[0031] The stabilizing mechanism includes a slide plate 25, one end of which is fixedly sleeved on the outside of the double-through rigid pipe 22. A retaining frame is vertically connected to the upper surface of the slide plate 25. A pressure rod 23 is slidably installed inside the retaining frame. The retaining frame has a rectangular frame structure, and a guide space is formed inside the retaining frame for the pressure rod 23 to pass through. A spring 24 is fitted outside the pressure rod 23 and inside the retaining frame. A retaining plate 27 is fixedly installed at the lower end of the pressure rod 23. Stabilizing wheels 26 are installed at both ends of the lower part of the retaining plate 27. The two sets of stabilizing wheels 26 are in rolling contact with the upper surface of the conveyor 1. The upper end of the retaining plate 27 slides through the slide plate 25. The spring 24 is always in a compressed state, and its elastic force pushes the pressure rod 23 and the retaining plate 27 downward, so that the stabilizing wheels 26 maintain rolling contact with the upper surface of the conveyor 1, ensuring that the height of the water blowing pipe 17 is constant and the blowing angle is stable during horizontal movement. The stabilizing wheels 26 are unpowered driven wheels, and their axles are rotatably installed on both sides below the retaining plate 27 through bearing seats. Two sets of stabilizing wheels 26 are rolledly connected to the upper end face of the conveyor 1 and roll along the upper end face of the conveyor 1 as the water pipe 17 moves horizontally with the cross frame 5.

[0032] A conveying method for processing aluminum alloy sheets, based on the aforementioned conveying device for processing aluminum alloy sheets, includes the following steps: S1: Place plate 4 at the feed end of conveyor 1, start the centering mechanism to center plate 4, and then transport the centered plate 4 along the upper surface of conveyor 1 in the discharge direction. Specifically, the operator places the corrugated aluminum alloy plate 4 to be conveyed at the feed end of the conveyor 1, ensuring that the length direction of the plate 4 is aligned with the conveying direction. Then, the centering mechanism is activated, and the telescopic ends of the two sets of cylinders 7 extend synchronously, pushing the centering push plate 8 to clamp the plate 4 from both sides towards the center, thus centering the plate 4 relative to the conveyor 1 in the width direction. After centering, the telescopic ends of the two sets of cylinders 7 retract synchronously, and the centering push plate 8 disengages from the plate 4. Next, the conveyor 1 is started, and the drive motor, through a reducer and transmission chain, drives each conveying roller to rotate synchronously, conveying the centered plate 4 along the upper surface of the conveyor 1 towards the discharge direction until the plate 4 reaches the preset lifting position. At this point, the conveyor 1 stops operating.

[0033] S2: Activate the telescopic assembly inside the cross frame 5, so that the telescopic end of the telescopic assembly pushes the sliding seat 14 to move until the front probe plate 12 fixedly connected to one side of the sliding seat 14 and the multiple wheels 19 on the movable plate 13 connected by the first hydraulic cylinder 16 are respectively inserted into the corrugated groove of the plate body 4. Specifically, the electric push cylinders 15, which span both sides of the interior of the frame 5, are activated to push the sliding seat 14 downward along the guide space of the frame base 11. The sliding seat 14 drives the front probe plate 12 and the movable plate 13 to move downward synchronously, so that the multiple wheels 19 on the upper surface of the front probe plate 12 and the movable plate 13 are respectively inserted into the corrugated grooves of the plate body 4. During the insertion of the wheels 19 into the corrugated grooves, the lower edge of the wheel body of the wheels 19 contacts or maintains a small gap with the bottom wall of the trough of the corrugated groove to ensure that the wheels 19 can smoothly enter the corrugated grooves without interfering with the crests. During this process, the visual contour scanner 30 can scan and identify the position of the corrugated grooves of the plate body 4 in advance, and the PLC controller controls the extension position of the electric push cylinders 15 according to the scanning data to ensure that the wheels 19 are accurately aligned with the corrugated grooves. When entering, the conveyor 1 can be started to cooperate with the plate body 4 to pass through.

[0034] S3: Keep the wheel 19 inserted into the corrugated groove, start the first hydraulic cylinders 16 on both sides of the sliding seat 14, drive the movable plate 13 to move relative to the front probe plate 12, so that the wheel 19 lifts one side of the plate 4 away from the upper surface of the conveyor 1 in the corrugated groove. Specifically, while maintaining the insertion of the rollers 19 into the corrugated groove, the extension of the first hydraulic cylinders 16 on both sides of the sliding seat 14 pushes the movable plate 13 upward relative to the sliding seat 14. The rollers 19 on the movable plate 13 move upward synchronously with the movable plate 13, and the wheels of the rollers 19 push the inner wall of the trough of the plate 4 obliquely upward within the corrugated groove. Since the rollers 19 on the front probe plate 12 maintain support at the front end of the plate 4, and the rollers 19 on the movable plate 13 are lifted upward, the two work together to lift the side of the plate 4 closest to the movable plate 13 away from the upper surface of the conveyor 1. At this time, the plate 4 forms an inclined posture with one side higher than the other in the width direction.

[0035] S4: Maintain the state where one side of the plate 4 is lifted, drive the plate feeding mechanism again, so that the cross frame 5 drives the sliding seat 14 and the lifted plate 4 to move in the horizontal direction towards the conveying direction, so as to realize the forward conveying of the plate 4. One end of the plate 4 contacts the upper surface of the conveyor 1. At this time, the plate 4 is in an inclined state, and the conveyor 1 stops conveying. Specifically, while maintaining the tilted state of one side of the plate 4, the second hydraulic cylinder 21 pushes the clamping plate 20 forward along the guide direction of the guide rod. The clamping plate 20 drives the platform 2 to move forward synchronously, and the platform 2 drives the cross frame 5, which is fixedly connected to it, to slide forward along the guide direction of the two slide rods 6. The cross frame 5 drives the sliding seat 14 and the lifted plate 4 to move horizontally in the conveying direction, realizing the forward conveying of the plate 4. During this process, the end of the plate 4 that is not lifted always maintains sliding contact with the upper surface of the conveyor 1, and the plate 4 moves forward in an tilted state. At this time, the conveyor 1 stops operating actively and only serves as a sliding support surface for one end of the plate 4.

[0036] S5: Then, water is blown at the upper and lower ends of the plate 4. During the horizontal movement of the plate 4 across the frame 5, the air intake mechanism at the lower ends of both sides of the sliding seat 14 is activated, so that high-pressure gas enters the two water blowing pipes 17 of the water blowing mechanism through the air intake mechanism. The nozzle 28 of the upper water blowing pipe 17 sprays the upper surface of the plate 4 obliquely downward, while the nozzle 28 of the lower water blowing pipe 17 sprays the lower surface of the plate 4 obliquely upward, so as to remove the residual processing fluid or moisture on the surface of the plate.

[0037] Working Principle: First, the corrugated aluminum alloy plate 4 to be conveyed is placed at the feed end of conveyor 1. The centering mechanisms located on both sides of conveyor 1 near the feed point are activated. The telescopic ends of two sets of cylinders 7 extend synchronously, pushing the centering push plates 8, which are fixedly connected to each other, to clamp the plate 4 from both sides towards the center, aligning the plate 4 with the conveyor 1 in the width direction. After centering, the telescopic ends of the two sets of cylinders 7 retract, and the centering push plates 8 disengage from the plate 4. Subsequently, conveyor 1 starts, conveying the centered plate 4 a certain distance along the upper surface of conveyor 1 in the discharge direction, until the plate 4 reaches the preset lifting position, at which point conveyor 1 stops operating.

[0038] With the rollers 19 still inserted inside the corrugated groove, the first hydraulic cylinders 16 on both sides of the sliding seat 14 are activated. The telescopic ends of the first hydraulic cylinders 16 drive the movable plate 13 to move relative to the front probe plate 12, causing the rollers 19 on the movable plate 13 to push the inner wall of the trough of the plate 4 obliquely upward within the corrugated groove. Since the rollers 19 on the front probe plate 12 are supported at the front end, the conveyor 1 is started at this time. Through the conveying and propulsion of the conveyor 1, the rollers 19 on the movable plate 13 are lifted upward. The two work together to lift the side of the plate 4 closest to the movable plate 13 away from the upper surface of the conveyor 1. At this time, the plate 4 forms an inclined posture with one side higher than the other in the width direction. The water or processing fluid that originally accumulated in the trough groove of the plate 4 begins to converge and flow to the lower position under the action of gravity.

[0039] Then, maintaining the tilted state of one side of the plate 4 being lifted, the plate feeding mechanism is activated. The telescopic end of the second hydraulic cylinder 21 inside the lifting platform 9 extends, pushing the clamping plate 20 to move. The clamping plate 20 drives the fixedly connected platform 2 to move synchronously. Since the platform 2 is fixedly connected to the cross frame 5, the cross frame 5 slides on the two sliding rods 6, driving the sliding seat 14 and the lifted plate 4 to move horizontally in the conveying direction, realizing the forward conveying of the plate 4. During this process, the end of the plate 4 that is not lifted always maintains sliding contact with the upper surface of the conveyor 1. The plate 4 moves forward in an inclined state. At this time, the conveyor 1 stops operating actively and only serves as a sliding support surface for one end of the plate 4.

[0040] During the horizontal movement of the conveyor plate 4 across the transverse frame 5, the air intake mechanisms at the lower ends of both sides of the sliding seat 14 are activated. The high-pressure gas generated by the air pump 10 is pressurized by the booster valve 31 and enters the lower water blowing pipe 17 in the water blowing mechanism through the conveyor pipe 29. Since the two water blowing pipes 17 are connected by a double-pass rigid pipe 22, the high-pressure gas simultaneously enters both the upper and lower water blowing pipes 17. The two water blowing pipes 17 are symmetrically arranged on the upper and lower sides of the plate 4, and multiple nozzles 28 are installed at equal intervals along the horizontal direction inside the water blowing pipes 17. The nozzles 28 at the upper water blowing pipe 17 spray downwards to one side, applying high-pressure air to the upper surface of the plate 4, forcibly blowing away the accumulated water in the grooves of the upper surface downwards; the nozzles 28 at the lower water blowing pipe 17 spray upwards to one side, applying high-pressure air to the lower surface of the plate 4, blowing away the residual processing fluid or water on the lower surface upwards. The staggered airflow directions cover the entire concave and convex section of the corrugated sheet, driving away any residual processing fluid and moisture inside the grooves. During this process, the stabilizing mechanism outside the double-through rigid pipe 22 is connected to the upper surface of the conveyor 1 via a sliding plate 25, a pressure rod 23, a spring 24, a clamping plate 27, and two sets of stabilizing wheels 26, ensuring that the water blowing pipe 17 maintains a stable spray height and angle as it moves with the crossbeam 5. The clamping seats 18 on one side of the front probe plate 12, near both ends of the water blowing pipe 17, provide auxiliary support to prevent the water blowing pipe 17 from shaking during the spraying process.

[0041] After the water blowing process is completed, the plate feeding mechanism reverses its movement. The extension and retraction of the second hydraulic cylinder 21, through the clamping plate 20 and the platform 2, drives the cross frame 5 and the sliding seat 14 to move in the opposite direction in the horizontal direction, smoothly removing the wheel 19 from the corrugated groove of the plate 4. At the same time, the extension and retraction end of the first hydraulic cylinder 16 resets, and the movable plate 13 returns to its initial position. After the wheel 19 is completely out of the range of the plate 4, the conveyor 1 restarts, continuing to transport the water-dried plate 4 to the downstream drying station or the next process, entering the next work cycle.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
