Description

Technical Field

[0001] This invention relates to the field of copper plate production technology, specifically to a device for cleaning oil and impurities in copper plate production and its usage method. Background Technology

[0002] Copper plates and copper alloy strips are core basic materials in fields such as electronics, precision manufacturing, and aerospace. Their surface quality directly determines the success or failure of subsequent secondary processing such as electroplating, welding, and stamping, as well as the reliability of end products. With the continuous improvement of the requirements for material performance in high-end applications, modern high-precision copper plates need to have bright and flat surfaces, no pollutant residues, and resistance to atmospheric corrosion. In the production process of copper plate rolling, annealing, and cutting, various pollutants will inevitably be introduced. Oil and impurities used in the rolling process will remain on the plate surface. At the same time, dust in the production environment and solid impurities such as metal shavings generated during processing will also adhere to the surface, forming a composite pollution layer.

[0003] In continuous copper plate cleaning production lines, traditional unit spraying and brushing often uses fixed-angle columnar nozzles or simple fan-shaped nozzles. The spraying pressure is concentrated in the central area of ​​the copper plate, while the edges and corners form cleaning blind spots due to the obstruction of the spraying angle, resulting in higher levels of oil and impurities than in the central area. Moreover, single-sided spraying and brushing requires cleaning one side and then manually flipping or mechanically turning the plate to clean the other side, which is inefficient. During the flipping process, some waste liquid and impurities will penetrate the second side, resulting in poor consistency between the two sides and affecting product quality.

[0004] Based on this, the present invention designs an oil and impurity cleaning device for copper plate production and its usage method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an oil and impurity cleaning device and its usage method for copper plate production, in order to solve the problems mentioned in the background art, which are that traditional unit spray brushing often uses columnar nozzles or simple fan-shaped nozzles with fixed angles, the spray pressure is concentrated in the central area of ​​the copper plate, while the edges and corners form cleaning blind spots due to the obstruction of the spray angle; moreover, single-sided spray brushing requires cleaning one side and then manually flipping or mechanically turning the other side to be cleaned.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A device for cleaning oil and impurities in copper plate production includes a supporting base plate.

The driven wheel is fixed to one end of the lower steel plate drying assembly, which is installed at the end of the discharging roller conveyor. A filter box is fixed on the supporting base plate, and the back of the filter box is connected to the bottom end of the copper plate cleaning assembly.

[0007] As a further embodiment of the present invention, the copper plate cleaning assembly includes two hollow rotating drums. The two outer sides of the hollow rotating drums are rotatably connected to the frame through bearings. The hollow rotating drums are provided with a number of spray holes and a number of cleaning soft brushes are fixedly connected to them. The two hollow rotating drums are respectively fixed with a driving gear and a driven gear through the front side of the frame. The driving gear and the driven gear mesh with each other. The driving gear is fixed to the output shaft of the motor.

[0008] As a further embodiment of the present invention, one end of the hollow rotating cylinder passes through the rear side of the frame and is snapped with a first rotary joint. A branch pipe is sleeved inside the first rotary joint. The opposite ends of the two branch pipes are connected to a main water pipe. A circulation pump is installed at the bottom end of the main water pipe. The circulation pump is installed on the back of the filter box and its port extends into the interior of the filter box.

[0009] As a further embodiment of the present invention, the support assembly includes a movable frame, which is slidably connected inside the right-side isolation cover. Three telescopic rods are fixed to the top of the movable frame, and the top ends of the telescopic rods are fixed to the top of the inner wall of the isolation cover. Springs are sleeved on the telescopic rods and fixed between the top of the inner wall of the isolation cover and the movable frame. The two sides of the bottom of the movable frame are rotatably connected to the ends of the upper steel plate drying assembly through bearings.

[0010] As a further embodiment of the present invention, the steel plate drying assembly includes an air duct with several air holes on its exterior. The lower air duct is rotatably connected to one end of the discharge roller conveyor line near the frame via a bearing, and one end of the lower air duct that passes through the front side of the frame is fixed to the driven wheel.

[0011] As a further embodiment of the present invention, a second rotary joint is snapped onto the end of the air duct away from the driven wheel, a conduit is sleeved inside the second rotary joint, an air duct is connected to the opposite end of the two conduits, and a fan is connected to the bottom end of the air duct, the fan being installed on the back of the frame.

[0012] As a further embodiment of the present invention, side plates are fixed on both sides of the lower part of the frame, the copper plate cleaning assembly is located between the two side plates, and a through hole is opened on the back of the frame corresponding to the position of the upper air duct, and one end of the upper air duct slides through the through hole.

[0013] A method of using an oil and impurity cleaning device for copper plate production, the method comprising the following steps: During copper plate cleaning, the feeding roller conveyor smoothly transports the copper plate to be cleaned into the machine frame. Throughout the conveying process, the copper plate remains horizontal. Starting the motor causes its output shaft to drive the drive wheel to rotate, which in turn drives the driven wheel synchronously via belt transmission. Simultaneously, the motor output shaft directly drives the drive gear in the copper plate cleaning assembly. The drive gear meshes with the driven gear, causing the two hollow drums to rotate in opposite directions. When the circulating pump is running, it extracts clean water from the filter box, distributes it through the main water pipe to two branch pipes, and guides it into the hollow drums through the first rotary joint. The first rotary joint ensures the hollow drums are clean. When the hollow drum rotates, the water main pipe does not entangle. Several spray holes on the surface of the hollow drum evenly spray high-pressure water onto the upper and lower surfaces of the copper plate, impacting and peeling off the oil and loose impurities attached to the surface. Several soft cleaning brushes, which are set synchronously with the spray holes, rotate at high speed with the hollow drum to gently brush the surface of the copper plate. The soft cleaning brushes and the high-pressure water flow work together to remove stubborn oil and attached impurities through physical friction, while avoiding hard contact that could scratch the surface of the copper plate. The two hollow drums rotate in opposite directions, causing the soft cleaning brushes on their exteriors to rotate synchronously and in opposite directions to enhance the friction cleaning effect on the surface of the copper plate. The oily wastewater generated during cleaning is guided along the side plate to the bottom of the frame and finally flows into the filter box. After entering the filter box, the oily wastewater is filtered by the internal filtration structure to remove impurities and some floating oil. The purified water is then pumped out again by the circulation pump for cleaning operations. When the copper plate passes through the right isolation cover and comes into contact with the two steel plate drying components, the copper plate will squeeze the air duct in the upper steel plate drying component, causing the air duct to move the movable frame upward. The support component, through the elastic cooperation of the telescopic rod and the spring, makes the movable frame move the upper air duct to adaptively fit the upper surface of the copper plate. The preload of the spring ensures that the air duct and the copper plate remain in contact, which ensures the drying effect and avoids the air duct from squeezing and damaging the copper plate. At the same time, the upper air duct can move up and down to adapt to the drying needs of copper plates of different thicknesses. Secondly, the driven wheel driven by the motor simultaneously drives the air duct of the lower steel plate drying assembly to rotate, while the upper air duct adjusts its position adaptively and rotates synchronously with the movable frame. The end of the upper air duct moves in the through hole, which provides sliding and rotation space for the upper air duct. After the fan starts, the generated drying airflow is distributed to two ducts through the air duct and introduced into the air duct through the second rotary joint. The setting of the second rotary joint ensures that the air duct does not rotate with the air duct while it rotates. Several air holes on the surface of the air duct form a uniform air curtain, which blows from both the upper and lower sides of the copper plate at the same time. The rotating air duct makes the air curtain cover the entire surface of the copper plate, accelerating the evaporation of surface moisture and avoiding residual water stains from affecting the quality of the copper plate, achieving immediate drying after cleaning. Then, the two air ducts rotate relative to each other and convey the copper plate to the right until the copper plate is moved into the discharge roller conveyor line.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention places the copper plate to be cleaned on a feeding roller conveyor line. The output shaft of the motor drives the drive wheel to rotate, and the driven wheel rotates synchronously through belt transmission. At the same time, the output shaft of the motor directly drives the drive gear in the copper plate cleaning assembly. The drive gear meshes with the driven gear, driving two hollow drums to rotate in opposite directions. When the circulating pump is running, it draws out the cleaning water from the filter box, distributes it to two branch pipes through the main water pipe, and guides it into the hollow drum through the first rotary joint. The first rotary joint ensures that the main water pipe does not get tangled when the hollow drum rotates. Several spray holes on the surface of the hollow drum evenly spray high-pressure water onto the upper and lower surfaces of the copper plate, impacting and peeling off the surface-adhered coating. Oil stains and loose impurities are removed by several soft cleaning brushes that are set synchronously with the spray nozzles. These brushes rotate at high speed with the hollow drums, gently scrubbing the surface of the copper plate. The soft cleaning brushes work together with the high-pressure water flow to remove stubborn oil stains and attached impurities through physical friction, while avoiding hard contact that could scratch the surface of the copper plate. The two hollow drums rotate in opposite directions, causing the external soft cleaning brushes to rotate synchronously and in opposite directions, enhancing the friction cleaning effect on the surface of the copper plate. This method abandons the traditional single-sided fixed-angle spraying method. The copper plate cleaning component can completely cover all areas of the copper plate surface, without creating cleaning blind spots. Moreover, there is no need to flip the copper plate over for cleaning, ensuring consistent cleaning of both sides of the copper plate. 2. In this invention, when the right end of the copper plate comes into contact with the two steel plate drying components, the copper plate will press against the air duct in the upper steel plate drying component, causing the air duct to move the movable frame upward. The support component, through the elastic cooperation of the telescopic rod and the spring, allows the movable frame to drive the upper air duct to adaptively fit against the upper surface of the copper plate. The preload of the spring ensures that the air duct and the copper plate remain in contact, ensuring both the drying effect and preventing the air duct from squeezing and damaging the copper plate. At the same time, the upper air duct can move up and down to adapt to the drying needs of copper plates of different thicknesses, improving versatility. The driven wheel driven by the motor simultaneously drives the air duct of the lower steel plate drying component to rotate, while the upper air duct adaptively adjusts its position and rotates synchronously with the movable frame. After the fan starts, the generated drying airflow is distributed to two ducts through the air duct and introduced into the air duct through the second rotary joint. Several air holes in the air duct form a uniform air curtain, blowing simultaneously from the upper and lower sides of the copper plate. The rotating air duct makes the air curtain cover the entire surface of the copper plate, accelerating the evaporation of surface moisture, avoiding residual water stains that affect the quality of the copper plate, achieving immediate drying after cleaning, and ensuring the continuity of copper plate production.

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.

A copper plate cleaning assembly 5 is installed inside the frame 4. Isolation covers 9 are fixed on both sides inside the frame 4. The copper plate cleaning assembly 5 is located between the two isolation covers 9. A support assembly 10 is installed inside the right isolation cover 9. The bottom of the support assembly 10 and the inside of the frame 4 are rotatable. A steel plate drying assembly 12 is connected, and two steel plate drying assemblies 12 are on the same vertical line. A copper plate cleaning assembly 5 passes through the front side of the frame 4 and is connected to a motor 6. A drive wheel 7 is fixed on the output shaft of the motor 6. A belt 8 is sleeved on the drive wheel 7. A driven wheel 11 is sleeved inside the belt 8. The driven wheel 11 is fixed to one end of the lower steel plate drying assembly 12. The lower steel plate drying assembly 12 is installed at the end of the discharge roller conveyor line 3. A filter box 14 is fixed on the support base plate 1. The back of the filter box 14 is connected to the bottom end of the copper plate cleaning assembly 5. During operation, the output shaft of motor 6 is connected to copper plate cleaning assembly 5 and steel plate drying assembly 12, enabling it to simultaneously drive the rotating brushing of copper plate cleaning assembly 5 and the rotating air supply of steel plate drying assembly 12, ensuring that the cleaning and drying actions are synchronized and coordinated, and improving work efficiency.

[0020] As a further embodiment of the present invention, the copper plate cleaning assembly 5 includes two hollow rotating drums 501. The two outer sides of the hollow rotating drums 501 are rotatably connected to the frame 4 through bearings. The hollow rotating drums 501 are provided with a plurality of spray holes 502 and a plurality of cleaning soft brushes 503 are fixedly connected to them. The two hollow rotating drums 501 are respectively fixed with a drive gear 504 and a driven gear 505 through the front side of the frame 4. The drive gear 504 and the driven gear 505 mesh with each other. The drive gear 504 is fixed to the output shaft of the motor 6. During operation, starting the motor 6 causes the output shaft to drive the drive wheel 7 to rotate, which in turn drives the driven wheel 11 to rotate synchronously via the belt 8. Simultaneously, the output shaft of the motor 6 directly drives the drive gear 504 in the copper plate cleaning assembly 5. The drive gear 504 meshes with the driven gear 505, causing the two hollow drums 501 to rotate in opposite directions, thus causing the external cleaning brushes 503 to rotate synchronously and perform synchronous soft brushing on the upper and lower surfaces of the copper plate.

[0021] As a further embodiment of the present invention, one end of the hollow rotating drum 501 passes through the rear side of the frame 4 and is snapped with a first rotary joint 506. A branch pipe 507 is sleeved inside the first rotary joint 506. The opposite ends of the two branch pipes 507 are connected to a water guide main pipe 508. A circulation pump 509 is installed at the bottom end of the water guide main pipe 508. The circulation pump 509 is installed on the back of the filter box 14 and its port extends into the interior of the filter box 14. During operation, the circulating pump 509 draws out the clean water from the filter box 14 and distributes it to two branch pipes 507 through the main water pipe 508. The water is then introduced into the hollow rotating drum 501 through the first rotary joint 506. The first rotary joint 506 ensures that the main water pipe 508 does not get tangled when the hollow rotating drum 501 rotates. Several spray holes 502 on the surface of the hollow rotating drum 501 spray high-pressure water evenly onto the upper and lower surfaces of the copper plate, impacting and peeling off the oil and loose impurities attached to the surface.

[0022] As a further embodiment of the present invention, the support assembly 10 includes a movable frame 101, which is slidably connected inside the right isolation cover 9. Three telescopic rods 102 are fixed to the top of the movable frame 101. The top ends of the telescopic rods 102 are fixed to the top of the inner wall of the isolation cover 9. Springs 103 are sleeved on the telescopic rods 102. The springs 103 are fixed between the top of the inner wall of the isolation cover 9 and the movable frame 101. The two sides of the bottom of the movable frame 101 are rotatably connected to the ends of the upper steel plate drying assembly 12 through bearings. During operation, when the copper plate passes through the right isolation cover 9 and comes into contact with the two steel plate drying components 12, the copper plate will squeeze the air duct 121 in the upper steel plate drying component 12, causing the air duct 121 to drive the movable frame 101 to move upward. The support component 10, through the elastic cooperation of the telescopic rod 102 and the spring 103, causes the movable frame 101 to drive the upper air duct 121 to adaptively fit the upper surface of the copper plate. The preload of the spring 103 ensures that the air duct 121 and the copper plate remain in contact, which ensures the drying effect and avoids the air duct 121 from squeezing and damaging the copper plate. Furthermore, the upper air duct 121 can move up and down to adapt to the drying requirements of copper plates of different thicknesses, and the relative rotation of the two air ducts 121 can provide power to the copper plate, enabling the copper plate to move automatically to the right after cleaning and drying, thus improving the degree of automation.

[0023] As a further embodiment of the present invention, the steel plate drying assembly 12 includes a duct 121, with a plurality of air holes 122 on the outside of the duct 121. The lower duct 121 is rotatably connected to one end of the discharge roller conveyor line 3 near the frame 4 via a bearing. One end of the lower duct 121 that passes through the front side of the frame 4 is fixed to the driven wheel 11. A second rotary joint 123 is snapped onto the end of the duct 121 away from the driven wheel 11. A conduit 124 is sleeved inside the second rotary joint 123. One end of the two conduits 124 facing each other is connected to an air duct 125. The bottom end of the air duct 125 is connected to a fan 126. The fan 126 is installed on the back of the frame 4. During operation, after the fan 126 is started, the generated dry airflow is distributed to two ducts 124 through the air duct 125 and introduced into the air duct 121 through the second rotary joint 123. The second rotary joint 123 is designed so that the air duct 125 does not rotate with the air duct 121 while it rotates. Several air holes 122 on the surface of the air duct 121 form a uniform air curtain, which blows from both the top and bottom sides of the copper plate at the same time. The rotating air duct 121 makes the air curtain cover the entire surface of the copper plate, accelerating the evaporation of surface moisture.

[0024] As a further embodiment of the present invention, side plates 13 are fixed on both sides of the lower part of the frame 4, and the copper plate cleaning assembly 5 is located between the two side plates 13. The oily wastewater generated during cleaning is guided along the side plates 13 to the bottom of the frame 4 and finally flows into the filter box 14. After the oily wastewater enters the filter box 14, the impurity particles and some floating oil in the wastewater are removed by the internal filtration structure. The purified water is then pumped out again by the circulation pump 509 for cleaning operations. A through hole 15 is provided on the back of the frame 4 corresponding to the position of the upper air duct 121, and one end of the upper air duct 121 slides through the through hole 15. The end of the upper air duct 121 will move in the through hole 15. The through hole 15 provides sliding and rotation space for the upper air duct 121.

[0025] A method for using an oil and impurity cleaning device for copper plate production, comprising the following steps: During copper plate cleaning, the feeding roller conveyor 2 smoothly transports the copper plate to be cleaned into the frame 4. During the conveying process, the copper plate remains horizontal. The motor 6 is started, and its output shaft drives the drive wheel 7 to rotate. This is transmitted via the belt 8, causing the driven wheel 11 to rotate synchronously. Simultaneously, the output shaft of the motor 6 directly drives the drive gear 504 in the copper plate cleaning assembly 5. The drive gear 504 meshes with the driven gear 505, causing the two hollow drums 501 to rotate in opposite directions. When the circulating pump 509 is running, it draws clean water from the filter box 14, distributes it through the main water pipe 508 to two branch pipes 507, and guides it into the hollow drums 501 through the first rotary joint 506. 06 Ensure that the water main pipe 508 does not get tangled when the hollow drum 501 rotates. Several spray holes 502 on the surface of the hollow drum 501 spray high-pressure water evenly onto the upper and lower surfaces of the copper plate, impacting and peeling off the oil and loose impurities attached to the surface. Several cleaning soft brushes 503 set synchronously with the spray holes 502 rotate at high speed with the hollow drum 501 to gently brush the surface of the copper plate. The cleaning soft brushes 503 and the high-pressure water flow work together to remove stubborn oil and attached impurities through physical friction, while avoiding hard contact that could scratch the surface of the copper plate. The two hollow drums 501 rotate in opposite directions, causing the cleaning soft brushes 503 on their exteriors to rotate synchronously, with opposite directions to enhance the friction cleaning effect on the surface of the copper plate. The oily wastewater generated during cleaning is guided along the side plate 13 to the bottom of the frame 4 and finally flows into the filter box 14. After entering the filter box 14, the oily wastewater is filtered by the internal filtration structure to remove impurities and some floating oil. The purified water is then pumped out again by the circulation pump 509 for cleaning operations. When the copper plate passes through the right isolation cover 9 and comes into contact with the two steel plate drying components 12, the copper plate will squeeze the air duct 121 in the upper steel plate drying component 12, causing the air duct 121 to drive the movable frame 101 to move upward. The support component 10, through the elastic cooperation of the telescopic rod 102 and the spring 103, causes the movable frame 101 to drive the upper air duct 121 to adaptively fit the upper surface of the copper plate. The preload of the spring 103 ensures that the air duct 121 and the copper plate remain in contact, which ensures the drying effect and avoids the air duct 121 from squeezing and damaging the copper plate. At the same time, the upper air duct 121 can move up and down to adapt to the drying needs of copper plates of different thicknesses. Secondly, the driven wheel 11 driven by motor 6 simultaneously drives the air duct 121 of the lower steel plate drying assembly 12 to rotate. The upper air duct 121 adaptively adjusts its position and rotates synchronously with the movable frame 101. The end of the upper air duct 121 moves in the through hole 15, which provides sliding and rotation space for the upper air duct 121. After the fan 126 is started, the generated drying airflow is distributed to two ducts 124 through the air duct 125 and introduced into the air duct 121 through the second rotary joint 123. The head 123 is designed so that the air duct 125 does not rotate with the air duct 121 while it rotates. Several air holes 122 on the surface of the air duct 121 form a uniform air curtain of drying airflow, which blows from both the top and bottom sides of the copper plate at the same time. The rotating air duct 121 makes the air curtain cover the entire surface of the copper plate, accelerating the evaporation of surface moisture and avoiding residual water stains from affecting the quality of the copper plate. This achieves immediate drying after cleaning. Then, the two air ducts 121 rotate relative to each other and convey the copper plate to the right until the copper plate is moved into the discharge roller conveyor line 3.

The second rotary joint (123) is fitted with a conduit (124). The opposite ends of the two conduits (124) are connected to an air duct (125). The bottom end of the air duct (125) is connected to a fan (126). The fan (126) is installed on the back of the frame (4).

5. The oil and impurity cleaning device for copper plate production according to claim 4, characterized in that: Side plates (13) are fixed on both sides of the lower part of the frame (4). The copper plate cleaning assembly (5) is located between the two side plates (13). A through hole (15) is opened on the back of the frame (4) corresponding to the position of the upper air duct (121), and one end of the upper air duct (121) slides through the through hole (15).

6. A method of using an oil and impurity cleaning device for copper plate production, as described in claim 5, characterized in that... The method of use includes the following steps: During the cleaning of the copper plate, the feeding roller conveyor (2) smoothly transports the copper plate to be cleaned into the frame (4). During the conveying process, the copper plate always maintains a horizontal posture. By starting the motor (6), its output shaft drives the drive wheel (7) to rotate. Through the belt (8), the driven wheel (11) rotates synchronously. At the same time, the output shaft of the motor (6) directly drives the drive gear (504) in the copper plate cleaning assembly (5). The drive gear (504) meshes with the driven gear (505), driving the two hollow drums (501) to rotate in opposite directions. When the circulating pump (509) is running, it draws out the clean water in the filter box (14), distributes it to the two branch pipes (507) through the main water pipe (508), and introduces it into the hollow drum (501) through the first rotary joint (506). The first rotary joint (506) ensures that the water guide pipe (508) does not get tangled when the hollow drum (501) rotates. Several spray holes (502) on the surface of the hollow drum (501) spray high-pressure water evenly onto the upper and lower surfaces of the copper plate, impacting and peeling off the oil stains and loose impurities attached to the surface. Several cleaning soft brushes (503) set synchronously with the spray holes (502) rotate at high speed with the hollow drum (501) to perform soft brushing on the surface of the copper plate. The cleaning soft brushes (503) and the high-pressure water flow work together to remove stubborn oil stains and attached impurities through physical friction, while avoiding hard contact that could scratch the surface of the copper plate. The two hollow drums (501) rotate in opposite directions, causing the cleaning soft brushes (503) on their exteriors to rotate synchronously, with opposite directions to enhance the friction cleaning effect on the surface of the copper plate. The oily wastewater generated during cleaning is guided along the side plate (13) to the bottom of the frame (4) and finally flows into the filter box (14). After entering the filter box (14), the oily wastewater is filtered by the internal filtration structure to remove impurities and some floating oil. The purified water is then pumped out again by the circulation pump (509) for cleaning operations. When the copper plate passes through the right isolation cover (9) and comes into contact with the two copper plate drying components (12), the copper plate will squeeze the air duct (121) in the upper copper plate drying component (12), causing the air duct (121) to... The movable frame (101) is moved upward. The support component (10) is elastically engaged with the spring (103) through the telescopic rod (102), so that the movable frame (101) drives the upper air duct (121) to adaptively fit the upper surface of the copper plate. The preload of the spring (103) ensures that the air duct (121) and the copper plate remain in contact, which not only ensures the drying effect, but also avoids the air duct (121) from squeezing and damaging the copper plate. At the same time, the upper air duct (121) can move up and down to adapt to the drying requirements of copper plates of different thicknesses. The driven wheel (11) driven by the motor (6) simultaneously drives the air duct (121) of the lower copper plate drying assembly (12) to rotate. The upper air duct (121) adjusts its position adaptively and rotates synchronously with the movable frame (101). The end of the upper air duct (121) moves in the through hole (15), which provides sliding and rotation space for the upper air duct (121). After the fan (126) is started, the generated drying airflow is distributed to two ducts (124) through the air duct (125) and introduced into the air duct (121) through the second rotary joint (123). The second rotary joint (123) is set so that the air duct (125) will not rotate along with the air duct (121) while the air duct (121) rotates. Several air holes (122) on the surface of the air duct (121) form a uniform air curtain of drying airflow, which blows from the upper and lower sides of the copper plate at the same time. The rotating air duct (121) makes the air curtain cover the entire surface of the copper plate, accelerates the evaporation of surface moisture, avoids residual water stains from affecting the quality of the copper plate, and achieves immediate drying after cleaning. At the same time, the two air ducts (121) rotate relative to each other and convey the copper plate to the right until the copper plate is moved into the discharge roller conveyor line (3).
