Description

Technical Field

[0001] This invention relates to the field of copper coil processing technology, specifically to an automated copper coil surface grinding and rust removal mechanism. Background Technology

[0002] Copper is a non-ferrous metal widely used in various sectors of the national economy, including power, electronics, aviation, aerospace, shipbuilding, metallurgy, transportation, textiles, and construction. Copper is also a durable metal that can be recycled multiple times without losing its mechanical properties. However, over time, copper will corrode; the corroded parts are called verdigris, which needs to be removed after copper is recycled.

[0003] A search revealed Chinese patent application CN201410057257.0, which proposes a method and apparatus for differential speed leveling and rust removal of hot-rolled steel plates. The apparatus includes a left coiler, a right coiler, a left guide roller, a right guide roller, and 1-3 four-roll or six-roll leveling machines. The hot-rolled steel plate is leveled and rolled by a leveling machine equipped with upper and lower metal texturing rollers. The uneven surface of the metal texturing rollers is subjected to differential speed leveling and rust removal at a pressure of 60t-1000t and a differential speed of 5-500 m / min, breaking down and erasing the iron oxide scale, surface stains, and various surface defects adhering to the surface of the hot-rolled steel plate. The speed difference between the upper and lower metal texturing rollers and the hot-rolled steel plate is equal in magnitude but opposite in direction. This invention uses a metal texturing roller mounted on a leveling machine to differentially level hot-rolled steel plates, removing iron oxide scale from the surface of the hot-rolled steel plates, avoiding environmental pollution, and simultaneously eliminating the yield plateau of the hot-rolled steel plates, thus improving the surface quality of the hot-rolled steel plates; the prior art removes rust using a leveling machine, but this method is not suitable for removing verdigris.

[0004] The search also yielded Chinese patent application CN201720841224.4, which discloses a rust removal device for copper strip processing. The device includes a cleaning box, a first winding device fixedly installed on the left side plate of the cleaning box, and a cleaning tank fixedly installed at the bottom of the inner cavity of the cleaning box. The cleaning box contains evenly distributed first drive rollers. The copper strip inside the first winding device is sequentially wound around the outside of each set of first drive rollers. A first rust-removing roller is located on the upper side of the copper strip, and second rust-removing rollers are located on both sides of the first rust-removing rollers. Both the first and second rust-removing rollers are hinged to the cleaning box via bearing seats. This invention, by using the first rust-removing rollers, second rust-removing rollers, and cleaning tanks in combination, can brush off the rust from the surface of the copper strip, followed by cleaning in the cleaning tank. This results in better rust removal, saves a significant amount of time, effectively improves work efficiency, and reduces the workload of workers. The existing technology uses large equipment with low rust removal efficiency.

[0005] Therefore, we propose an automated copper coil surface grinding and rust removal mechanism. Summary of the Invention

[0006] The purpose of this invention is to provide an automated copper coil surface grinding and rust removal mechanism to solve at least one of the problems mentioned in the background art.

[0007] This application provides an automated copper coil surface grinding and rust removal mechanism, including:

[0008] A rust removal tank is used to hold rust remover. A partition is fixed in the middle of the interior of the rust removal tank. The partition divides the rust removal tank into a rust removal area and a drying area. The rust removal area holds the rust remover.

[0009] A grinding mechanism, used to simultaneously grind the upper and lower surfaces of the copper sheet, is located in the rust removal zone.

[0010] By adopting the above technical solution, and by setting up a rust removal tank, when the rusted copper coil is placed on the unwinding equipment, the copper sheet is pulled out and passes through the rust remover in the rust removal tank to remove rust. At the same time as the rust remover removes rust, the upper and lower surfaces of the copper sheet can be polished, thereby removing the verdigris from the upper and lower surfaces of the copper sheet simultaneously. After the verdigris is removed, the copper sheet enters the drying area to dry, thus achieving the drying operation of the copper sheet. Finally, the copper sheet is wound up by the winding equipment into a rust-removed copper coil.

[0011] Preferably, the grinding mechanism includes a horizontally placed U-shaped plate, a slider is fixed to the bottom of the U-shaped plate, and rust-removing brushes are provided on both the upper and lower inner walls of the U-shaped plate, with the copper sheet passing through two of the rust-removing brushes.

[0012] By adopting the above technical solution, the U-shaped plate can wrap the copper sheet. When the copper sheet passes through the U-shaped plate, it will inevitably be rubbed on the rust removal brush. Under the friction of the rust removal brush, the patina on the surface of the copper sheet can be removed.

[0013] Preferably, it also includes a swaying mechanism for horizontal movement of the U-shaped plate.

[0014] By adopting the above technical solution, the efficiency of copper patina removal can be further improved. When the shaking mechanism is running, the friction efficiency can be increased more quickly, and the winding equipment can wind up faster, which can improve the efficiency of copper patina removal.

[0015] Preferably, the shaking mechanism includes a placement box fixed on the rust removal tank, one end of which extends to the outside of the rust removal tank. The U-shaped plate is located inside the placement box, and a connecting plate is fixed to the side of the U-shaped plate. A circular hole is provided on the connecting plate, and a protrusion is circumferentially fixed to the inner wall of the circular hole. A rotating shaft is rotatably mounted on the inner wall of the placement box, and the rotating shaft is coaxial with the circular hole. A pressing block is fixed to the outer wall of the rotating shaft, and the pressing block and the protrusion are on the same plane. A spring reset mechanism for resetting the connecting plate is provided between the connecting plate and the placement box. A drive mechanism for driving the rotating shaft to rotate is provided on the rust removal tank.

[0016] By adopting the above technical solution, when the drive mechanism is running, it can drive the rotating shaft to rotate, and then the rotating shaft drives the pressing block to rotate. When the pressing block rotates, it can press against the protruding block. After the protruding block is pressed, the connecting plate and U-shaped plate will shake. The spring reset mechanism can drive the connecting plate and U-shaped plate to reset when the pressing block does not press against the protruding block. The reset also achieves another shaking, which can continuously polish the upper and lower surfaces of the copper sheet, improving the polishing effect and efficiency.

[0017] Preferably, the spring reset mechanism includes two corner plates, which are disposed at the two corners of the connecting plate, and reset springs are fixed between the two sides of the corner plates and the placement box.

[0018] By adopting the above technical solution and setting the corner plates, the structure of the spring reset mechanism can be greatly simplified and the cost can be effectively reduced. Only two corner plates are needed to achieve a good reset effect. It is worth noting that one corner plate can also achieve reset, but two corner plates have a better reset effect.

[0019] Preferably, the driving mechanism is a drive motor, which is fixed on the outer wall of the rust removal tank, and the output end of the drive motor is fixedly connected to the rotating shaft through a coupling.

[0020] By adopting the above technical solution, when in use, the drive motor drives the rotation of the rotating shaft, thereby realizing the electric drive of the rotating shaft.

[0021] Preferably, the rust removal pool located in the rust removal zone has a feed opening on its side, and the rust removal pool located in the drying zone has a discharge opening on its side. Inside the rust removal pool, a first pair of rollers, two horizontally arranged first guide rollers, a second guide roller, two parallelly arranged drying rollers, and a second pair of rollers are rotatably installed in sequence. The first pair of rollers and the two first guide rollers are located in the rust removal zone, the second guide rollers are located on the top of the partition, and the two drying rollers and the second pair of rollers are located in the drying zone.

[0022] By adopting the above technical solution, during use, the copper sheet sequentially enters the middle of the first pair of rollers, the bottom of the two first guide rollers, the top of the second guide roller, the bottom of the two drying rollers, and the middle of the second pair of rollers. The first guide roller and the drying roller are located in the lower part of the rust removal tank, which facilitates the contact between the rust remover and the copper sheet and facilitates drying. It is worth noting that the drying roller has a heating function, and a fan can be installed in the drying area to quickly dry the copper sheet.

[0023] Preferably, the top of the partition plate has an arc-shaped opening on the side near the rust removal area, and the second guide roller is located in the arc-shaped opening.

[0024] By adopting the above technical solution, the arc-shaped opening can make the overall structure more compact, and the cleaning liquid at the bottom of the copper sheet can flow to the second guide roller after contacting the second guide roller, and finally continue to flow to the arc-shaped opening and flow into the rust removal area along the partition, thus avoiding the waste of rust remover.

[0025] Preferably, the shaft on one of the first guide rollers extends to the outside of the rust removal tank and is fixed with a first bevel gear. A first mounting bracket is fixed on the outer wall of the rust removal tank. A drive shaft is rotatably mounted on the first mounting bracket. A second bevel gear that meshes with the first bevel gear is fixed at the lower end of the drive shaft. The drive shaft and the rotating shaft are connected by a belt drive mechanism.

[0026] By adopting the above technical solution, when the copper sheet passes through the first guide roller, there is friction between the copper sheet and the first guide roller, which can drive the first guide roller to rotate, which in turn drives the rotating shaft to rotate. This drives the first bevel gear to rotate, the first bevel gear to rotate, the second bevel gear to rotate, the second bevel gear to rotate, the drive shaft to rotate, the belt to rotate, the belt to rotate, and finally the pressure block to rotate, thus pressing against the protruding block and causing the U-shaped plate to sway.

[0027] Preferably, the placement box has openings on both sides for copper sheets to pass through.

[0028] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0029] This invention removes rust from copper sheets by pulling them out and passing them through a rust-removing tank with a rust-removing agent. While the rust-removing agent removes rust, the upper and lower surfaces of the copper sheet are polished, thereby removing the verdigris from both surfaces simultaneously. This allows for the rapid removal of verdigris from copper coils, and the equipment is compact.

[0030] When the shaking mechanism is running, the friction efficiency can be increased more quickly, and the winding device can wind up faster, which can improve the removal efficiency of copper patina. Attached Figure Description

[0040] Please see Figures 1-7 The present invention provides a technical solution: an automated copper coil surface grinding and rust removal mechanism, including a rust removal pool 2 and a grinding mechanism. A partition 23 is fixed in the middle of the interior of the rust removal pool 2, which is used to hold the rust remover. The partition 23 divides the rust removal pool 2 into a rust removal area and a drying area. The rust removal area holds the rust remover. The grinding mechanism for grinding the upper and lower surfaces of the copper sheet at the same time is set in the rust removal area. The rust removal pool 2 is set on the base plate 1.

[0041] By adopting the above technical solution, and with the setting of the rust removal tank 2, when the rusted copper coil is placed on the unwinding equipment, the copper sheet is pulled out and passes through the rust remover in the rust removal tank 2 to remove rust. At the same time as the rust remover removes rust, the upper and lower surfaces of the copper sheet can be polished, thereby removing the verdigris on the upper and lower surfaces of the copper sheet at the same time. After the verdigris is removed, the copper sheet enters the drying area to dry, realizing the drying operation of the copper sheet. Finally, the copper sheet is wound into a rust-removed copper coil by the winding equipment.

[0042] like Figures 3-4 As shown, in a specific embodiment of the present invention, the grinding mechanism includes a horizontally placed U-shaped plate 9, a slider 25 fixed to the bottom of the U-shaped plate 9, and rust-removing brushes 24 provided on both the upper and lower inner walls of the U-shaped plate 9, with the copper sheet passing through two rust-removing brushes 24.

[0043] By adopting the above technical solution, the U-shaped plate 9 can wrap the copper sheet. When the copper sheet passes through the U-shaped plate 9, it will inevitably rub against the rust removal brush 24. Under the friction of the rust removal brush 24, the patina on the surface of the copper sheet can be removed.

[0044] like Figures 1-5 As shown, in a specific embodiment of the present invention, a swaying mechanism for horizontal movement of the U-shaped plate 9 is also included.

[0045] By adopting the above technical solution, the efficiency of copper patina removal can be further improved. When the shaking mechanism is running, the friction efficiency can be increased more quickly, and the winding equipment can wind up faster, which can improve the efficiency of copper patina removal.

[0046] like Figures 1-5 As shown, in a specific embodiment of the present invention, the shaking mechanism includes a placement box 7 fixed on the rust removal pool 2, one end of the placement box 7 extending to the outside of the rust removal pool 2, a U-shaped plate 9 located inside the placement box 7, a connecting plate 14 fixed to the side of the U-shaped plate 9, a circular hole provided on the connecting plate 14, a protrusion 16 circumferentially fixed on the inner wall of the circular hole of the connecting plate 14, a rotating shaft 12 rotatably mounted on the inner wall of the placement box 7, the rotating shaft 12 being coaxially arranged with the circular hole, a pressing block 15 fixed on the outer wall of the rotating shaft 12, and the pressing block 15 and the protrusion 16 being on the same plane, a spring reset mechanism for resetting the connecting plate 14 is provided between the connecting plate 14 and the placement box 7, and a driving mechanism for driving the rotating shaft 12 to rotate is provided on the rust removal pool 2.

[0047] By adopting the above technical solution, when the drive mechanism is running, it can drive the rotating shaft 12 to rotate, and then the rotating shaft 12 drives the pressing block 15 to rotate. When the pressing block 15 rotates, it can press against the protruding block 16. After the protruding block 16 is pressed, the connecting plate 14 and the U-shaped plate 9 will shake. The spring reset mechanism can drive the connecting plate 14 and the U-shaped plate 9 to reset when the pressing block 15 does not press against the protruding block 16. When the reset is achieved, another shaking is achieved, which can continuously polish the upper and lower surfaces of the copper sheet, improving the polishing effect and efficiency.

[0048] like Figures 4-5 As shown, in a specific embodiment of the present invention, the spring reset mechanism includes two corner plates 21, which are disposed on the two corners of the connecting plate 14, and reset springs 22 are fixed between the two sides of the corner plates 21 and the placement box 7.

[0049] By adopting the above technical solution and setting the corner plate 21, the structure of the spring reset mechanism can be greatly simplified and the cost can be effectively reduced. Only two corner plates 21 are needed to achieve a good reset effect. It is worth noting that one corner plate 21 can also achieve reset, and two corner plates 21 have a better reset effect.

[0050] In a specific embodiment of the present invention, as one implementation of the driving mechanism, the driving mechanism adopts a driving motor (not shown in the figure), the driving motor is fixed on the outer wall of the rust removal tank 2, and the output end of the driving motor is fixedly connected to the rotating shaft 12 through a coupling.

[0051] By adopting the above technical solution, when in use, the drive motor drives the rotation of the rotating shaft 12, thereby realizing the electric drive of the rotating shaft 12.

[0052] like Figure 1 and Figure 7 As shown, in a specific embodiment of the present invention, a feed opening 201 is provided on the side of the rust removal pool 2 located in the rust removal zone, and a discharge opening 202 is provided on the side of the rust removal pool 2 located in the drying zone. Inside the rust removal pool 2, a first pair of rollers 8, two horizontally arranged first guide rollers 6, a second guide roller 5, two parallelly arranged drying rollers 3, and a second pair of rollers 4 are rotatably installed in sequence. The first pair of rollers 8 and the two first guide rollers 6 are located in the rust removal zone, the second guide roller 5 is located on the top of the partition plate 23, and the two drying rollers 3 and the second pair of rollers 4 are located in the drying zone.

[0053] By adopting the above technical solution, during use, the copper sheet sequentially enters the middle of the first pair of rollers 8, the bottom of the two first guide rollers 6, the top of the second guide roller 5, the bottom of the two drying rollers 3, and the middle of the second pair of rollers 4. The first guide rollers 6 and the drying rollers 3 are located in the lower part of the rust removal pool 2, which facilitates the contact between the rust remover and the copper sheet and facilitates drying. It is worth noting that the drying rollers 3 have a heating function, and a fan can be installed in the drying area to quickly dry the copper sheet.

[0054] like Figure 6 As shown, in a specific embodiment of the present invention, an arc-shaped opening is provided on the top side of the partition 23 near the rust removal area, and the second guide roller 5 is located in the arc-shaped opening.

[0055] By adopting the above technical solution, the arc-shaped opening can make the overall structure more compact, and the cleaning liquid at the bottom of the copper sheet can flow to the second guide roller 5 after contacting the second guide roller 5, and finally continue to flow to the arc-shaped opening and flow into the rust removal area along the partition 23, thus avoiding the waste of rust remover.

[0056] like Figure 2 and Figure 5 As shown, in a specific embodiment of the present invention, a rotating shaft 18 on one of the first guide rollers 6 extends to the outside of the rust removal pool 2 and is fixed with a first bevel gear 19. A first mounting bracket 11 is fixed on the outer wall of the rust removal pool 2. A drive shaft 17 is rotatably mounted on the first mounting bracket 11. A second bevel gear 20 that meshes with the first bevel gear 19 is fixed at the lower end of the drive shaft 17. The drive shaft 17 and the rotating shaft 12 are connected by a belt drive mechanism 13. In order to improve the stability of the rotating shaft 12, a second mounting bracket 10 is also fixed on the rust removal pool 2. The rotating shaft 12 is rotatably mounted on the second mounting bracket 10, specifically by bearings. It is worth noting that the belt drive mechanism 13 includes a belt and pulleys. The pulleys are mounted on the corresponding rotating shaft 12 and drive shaft 17, and the belt is sleeved on the two pulleys.

[0057] By adopting the above technical solution, when the copper sheet passes through the first guide roller 6, there is friction between the copper sheet and the first guide roller 6, which can drive the first guide roller 6 to rotate, which in turn drives the rotating shaft 18 to rotate. This drives the first bevel gear 19 to rotate, the first bevel gear 19 to rotate, the second bevel gear 20 to rotate, the second bevel gear 20 to rotate, the drive shaft 17 to rotate, and the belt to rotate. The belt can drive the rotating shaft 12 to rotate, and finally the pressing block 15 to rotate, thereby pressing against the protruding block 16 and causing the U-shaped plate 9 to sway.

[0058] like Figure 5 As shown, in a specific embodiment of the present invention, openings 701 for copper sheets to pass through are provided on both sides of the placement box 7.

[0059] Working principle: With the setting of rust removal tank 2, when the rusted copper coil is placed in the unwinding equipment, the copper sheet is pulled out and passes through the rust remover in rust removal tank 2 to remove rust. At the same time as the rust remover removes rust, the upper and lower surfaces of the copper sheet can be polished, thereby removing the verdigris on the upper and lower surfaces of the copper sheet at the same time. After the verdigris is removed, the copper sheet enters the drying area to dry, realizing the drying operation of the copper sheet. Finally, the copper sheet is wound into a rust-removed copper coil by the winding equipment.

[0060] When the drive mechanism is running, it can drive the rotating shaft 12 to rotate, which in turn drives the pressing block 15 to rotate. When the pressing block 15 rotates, it can press against the protruding block 16. After the protruding block 16 is pressed, the connecting plate 14 and the U-shaped plate 9 will shake. The spring reset mechanism can drive the connecting plate 14 and the U-shaped plate 9 to reset when the pressing block 15 is not pressing against the protruding block 16. The reset will cause another shaking, which can continuously polish the upper and lower surfaces of the copper sheet, improving the polishing effect and efficiency.
