Description

Technical Field

[0001] The present invention relates to the technical field of copper strip processing, and particularly to a degreasing and cleaning device for the surface of a copper strip. Background Art

[0002] During the processing, transportation, and storage of copper strips, the surface will be contaminated with pollutants such as oil stains, dust, and fingerprints. These pollutants not only affect the appearance of the copper strip but may also reduce its physical properties such as electrical conductivity and thermal conductivity. Through degreasing and cleaning, these pollutants can be effectively removed, and the cleanliness of the copper strip surface can be restored. Degreasing and cleaning can also remove the tiny burrs and uneven parts on the surface of the copper strip, improve its surface roughness, enhance the processing performance and product quality of the copper strip. In the degreasing and cleaning of the copper strip surface, it is mostly carried out by reagents at the same time. During the cleaning, no treatment such as polishing is performed on the copper strip surface. Although reagent cleaning can remove most of the surface oil stains, for some stubborn oil stains or oil stains embedded in the tiny pores on the copper strip surface, they cannot be completely removed. These residual oil stains will affect the subsequent processing performance and service life of the copper strip. And when the copper strip is exposed to the air, an oxide layer is easily formed on its surface. Some reagent cleaning cannot completely remove these oxide layers, resulting in a decline in the surface performance of the copper strip. Summary of the Invention

[0003] The purpose of the present invention is to provide a degreasing and cleaning device for the surface of a copper strip to solve the problems raised in the above background art.

Two support cylinders are rotatably connected to the middle of the end bracket. The ends of the two support cylinders are driven and connected through a spur gear set. A third motor connected to the spur gear set is fixedly connected to the bottom of the end bracket. An electromagnet is arranged inside the support cylinder. The bottom has magnetism when the electromagnet is energized. The electromagnet is fixedly connected to the end bracket.

[0010] Preferably, a plurality of limiting rods are fixedly connected at equal intervals inside the support cylinder. A cleaning brush is slidably connected to the middle of the limiting rod. Through holes corresponding to the bristles of the cleaning brush are arranged on the outer side of the support cylinder for scraping the dust outside the cleaning brush and correcting the bristles. A first spring is sleeved on the outer side of the limiting rod and between the inner wall of the support cylinder and the cleaning brush. A permanent magnet with the same magnetic pole as the electromagnet is fixedly connected to the top of the cleaning brush. When the electromagnet is energized, the repulsive force between the electromagnet and the permanent magnet is greater than the elastic force of the first spring. A second dust suction nozzle is fixedly connected to one side of the end bracket for cleaning the dust scraped outside the cleaning brush. When the cleaning brush rotates below the electromagnet, under the action of the repulsive force, the cleaning brush moves downward to clean the copper strip. When the cleaning brush is misaligned with the bottom of the electromagnet, under the action of the first spring, the cleaning brush slides into the support cylinder to scrape the impurities outside the cleaning brush and correct the cleaning brush.

[0011] Preferably, the cleaning part includes a support slide rail obliquely fixedly connected inside the brushing pool.

Water pipes communicated with the cleaning nozzle are arranged inside the second brush plate and the first brush plate. An electromagnetic reversing valve is fixedly connected to the end of the water pipe.

[0012] Preferably, a fourth motor is fixedly connected to the outside of the cleaning pool through a bracket. The output end of the fourth motor is fixedly connected to a driving disk, and an arc-shaped magnet is fixedly connected to the outside of the driving disk. A Hall sensor is fixedly connected to the outside of the bracket at a position corresponding to the arc-shaped magnet for controlling the alternating water output of the cleaning nozzles of the second brush plate and the first brush plate. The output end of the fourth motor is located at a position deviating from the center of the driving disk. A driving frame is slidably connected to the outside of the driving disk, and one end of the driving frame is fixedly connected to the second brush plate.

[0013] Preferably, two driving pipes are rotatably connected inside the air-drying pool. A water-absorbing sponge is fixedly connected to the outside of the driving pipe. The driving pipe is provided with a ventilation opening communicating with the water-absorbing sponge. An intake air duct connected to a high-pressure air source is fixedly connected inside the air-drying pool. The intake air duct is located inside the driving pipe. A connecting air nozzle for air outlet is arranged on the outside of the intake air duct. The connecting air nozzle is slidably connected to the inner wall of the driving pipe.

[0014] Preferably, an extrusion arc plate is fixedly connected inside the air-drying pool. The extrusion arc plate is located outside the water-absorbing sponge, and the radius of the extrusion arc plate gradually decreases along the direction of rotation of the driving pipe for squeezing out water when the water-absorbing sponge rotates. A water leakage hole is opened at the bottom of the extrusion arc plate. A water receiving funnel is fixedly connected inside the extrusion arc plate and below the extrusion arc plate.

[0015] Preferably, one end of the driving pipe is connected by spur gear transmission, and a second motor for driving the spur gear is fixedly connected to the outside of the air-drying pool.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The cleaning part drives the driving disk to rotate through the fourth motor. By using the cooperation of the driving disk and the driving frame, the second brush plate reciprocates on the support slide rail, and then drives the first brush plate to slide, realizing the reciprocating brushing of the copper strip by the second brush, improving the brushing effect. At the same time, during the brushing process, the arc-shaped magnet on the outside of the driving disk intermittently contacts the Hall sensor, controlling the electromagnetic reversing valve to be intermittently energized, so that the water of the cleaning nozzle alternately enters the first brush plate and the second brush plate to wash the second brush, ensuring that the bristles always maintain a good cleaning effect, and the water flow direction is constantly changed, reducing dirt accumulation and making the water flow cover the entire surface of the brush plate more evenly. A driving pipe with a water-absorbing sponge is arranged in the air-drying pool, and the water-absorbing sponge can adsorb and scrape off the water on the outside of the copper strip. At the same time, the driving pipe is driven to rotate by the second motor, so that the water-absorbed water-absorbing sponge rotates clockwise in the extrusion arc plate. The radius of the extrusion arc plate gradually decreases clockwise, squeezing the water-absorbing sponge to squeeze out the water, which flows through the water leakage hole to the water receiving funnel for collection.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1-14 The present invention provides a technical solution: a copper strip surface degreasing and cleaning device, comprising: a polishing box 1, a grinding roller 2 is rotatably provided inside the polishing box 1, and is used for grinding and polishing the surface of the copper strip; a driving rod 4 is rotatably connected to the polishing box 1, and the driving rod 4 is transmission-connected to the grinding roller 2; two spiral blades 5 are symmetrically fixed to the outside of the driving rod 4, and a brush 6 is fixed to the outside of the spiral blade 5, which is used for cleaning the copper strip and sweeping dust to both ends; a cleaning pool 9 is placed on one side of the polishing box 1, and a scrubbing pool, an ultrasonic cleaning pool and an air-drying pool are sequentially provided inside the cleaning pool 9 along the conveying direction of the copper strip; a cleaning part is provided inside the scrubbing pool, and is used for scrubbing and rinsing the copper strip at the same time; a plurality of guide rollers are equidistantly provided on the top and inside of the cleaning pool 9, and are used for conveying the copper strip in a wave shape.

[0034] It should be noted that, in this embodiment, the copper belt is passed through the polishing box 1 so that it is carried out between two sets of polishing rollers 2. Under the action of traction, the copper belt moves forward between the polishing rollers 2. During the transportation process, the polishing rollers 2 polish the copper belt and treat its surface. During this period, the dust on the outside of the copper belt is cleaned by the brush 6 driven by the spiral blade 5, and under the action of the spiral blade 5, the brush 6 transports the dust on the top of the copper belt to one end, so that it falls into the inside of the polishing box 1, which is convenient for its centralized collection. The polished copper belt is transported in a wave-like manner along the guide roller in the cleaning tank 9, and then in the middle of the ultrasonic cleaning tank, the electrical energy is converted into high-frequency sound waves by the ultrasonic transducer. During the propagation of ultrasonic waves, tiny bubbles are generated in the liquid. When the bubbles suddenly burst, huge energy is released, forming a high-temperature and high-pressure microenvironment. The pressure waves generated by cavitation can clean every detail of the copper strip. In combination with ultrasonic cleaning agents, ultrasonic vibrations are used to remove grease and fine dirt on the surface of the copper strip. After cleaning, the copper strip enters the air-drying tank for air-drying and water removal operations.

[0035] In one embodiment, a first motor 3 for driving the grinding roller 2 is fixedly connected to the outer side of the polishing box 1. The upper and lower grinding rollers 2 are connected by spur gears. A material baffle scraper 7 is fixedly connected inside the polishing box 1. The material baffle scraper 7 is concentric with the spiral blade 5 and has the same radius. A first suction nozzle 8 connected to a vacuum cleaner is fixedly connected to one side of the material baffle scraper 7 for cleaning the dust on the surface of the copper strip.

[0036] It should be noted that in this embodiment, two sets of grinding rollers 2 are provided, arranged vertically in each set. A spur gear is fixedly connected to one end of each grinding roller 2. The upper and lower grinding rollers 2 are connected by spur gears. A first motor 3 is fixedly connected to the outer side of the polishing box 1, and the output end of the first motor 3 is fixedly connected to the end of the grinding roller 2. One of the grinding rollers 2 is driven by a sprocket and a chain to drive the driving rod 4, so as to clean the position after grinding by the first brush 6 while grinding. A sliding brush for the copper strip is provided at the bottom of the material baffle scraper 7 to block the dust on the surface of the copper strip, and under the action of the spiral blade 5 and the first brush 6, it is conveyed forward to a designated position for convenient collection. And a first suction nozzle 8 is provided on one side of the material baffle scraper 7 to centrally collect the floating dust inside the polishing box 1. Two sets of vertically arranged grinding rollers are provided, connected by spur gears and driven by a motor, which can efficiently grind the surface of the copper strip; at the same time, the spiral blade and the first brush connected to the driving rod are used to timely clean the dust on the surface of the copper strip during grinding, and the dust is conveyed to the inside of the polishing box for centralized collection by the spiral blade, avoiding dust flying and affecting the working environment and the quality of subsequent processing.

[0037] In one embodiment, a cleaning assembly is further included, which includes an end bracket 13 fixedly connected to one end of the scrubbing pool, the middle part of the end bracket 13 is rotatably connected to two support cylinders 14, the ends of the two support cylinders 14 are connected through a spur gear set, the bottom of the end bracket 13 is fixedly connected to a motor 3 21 connected to the spur gear set, an electromagnet 19 is provided inside the support cylinder 14, the bottom of the electromagnet 19 is magnetic when energized, the electromagnet 19 is fixedly connected to the end bracket 13, a plurality of limit rods 17 are fixedly connected to the inside of the support cylinder 14 at equal distances, the middle part of the limit rod 17 is slidably connected to a cleaning brush 15, and the outer side of the support cylinder 14 is provided with a through hole corresponding to the bristles of the cleaning brush 15, which is used to scrape off dust on the outside of the cleaning brush 15 and correct the bristles. A spring 18 is provided on the outside of the limit rod 17 and between the inner wall of the support tube 14 and the cleaning brush 15. A permanent magnet 16 with the same magnetic pole as the electromagnet 19 is fixedly connected to the top of the cleaning brush 15. When the electromagnet 19 is energized, the repulsive force between the electromagnet 19 and the permanent magnet 16 is greater than the elastic force of the spring 18. A dust suction nozzle 20 is fixedly connected to one side of the end bracket 13, which is used to scrape dust off the outside of the cleaning brush 15 for cleaning. When the cleaning brush 15 rotates to the bottom of the electromagnet 19, under the action of the repulsive force, the cleaning brush 15 moves downward to clean the copper belt. When the cleaning brush 15 is misaligned with the bottom of the electromagnet 19, under the action of the spring 18, the cleaning brush 15 slides toward the inside of the support tube 14, thereby scraping off impurities on the outside of the cleaning brush 15 and correcting the cleaning brush 15.

[0038] It should be noted that in this embodiment, before the copper strip passes out of the interior of the polishing box 1 and enters the scrubbing pool, the copper strip contacts the cleaning brush 15 to clean the outer side of the copper strip again. The second suction nozzle 20 is connected to a vacuum cleaner to collect the impurities generated by the cleaning. During operation, the electromagnet 19 is continuously energized, so that a repulsive force is generated between the electromagnet 19 and the permanent magnet 16 located below it, causing the cleaning brush 15 to move downward along the limiting rod 17, so that the bottom of the cleaning brush 15 contacts the copper strip. Under the action of the timer and the controller, the third motor 21 drives the gear at one end of the lower support cylinder 14 to rotate through a gear. When the lower support cylinder 14 rotates, it drives the upper support cylinder 14 to rotate counterclockwise through a gear. When the permanent magnet 16 located below the electromagnet 19 rotates to a position deviating from the bottom of the electromagnet 19, under the elastic force of the first spring 18, the cleaning brush 15 moves along the limiting rod 17 towards the center of the support cylinder 14. During the movement of the cleaning brush 15, the bristles of the cleaning brush 15 are slidably connected to the corresponding through holes, so that the dust outside the bristles is scraped off and collected by the suction of the second suction nozzle 20, and the bristles retract into the through holes. Under the limiting action of the through holes, the bristles inclined due to friction can be corrected to prevent them from being inclined due to long-term friction, resulting in a decline in the cleaning effect. When the lower cleaning brush 15 rotates to the designated cleaning position, the other cleaning brushes 15 rotate below the electromagnet 19. Under the action of the repulsive force, the permanent magnet 16 drives the cleaning brush 15 to move downward, so as to clean the copper strip through the bristles at the bottom of the cleaning brush 15.

[0039] In one embodiment, the cleaning part includes a support slide rail 35 fixedly connected obliquely inside the scrubbing pool. A second brush plate 28 is slidably connected to the outside of the support slide rail 35. A linkage gear 33 is rotatably connected to the top of the second brush plate 28. A first fixed rack 31 meshing with the linkage gear 33 is fixedly connected to one end of the support slide rail 35. A second spring 32 is fixedly connected between the support slide rail 35 and the second brush plate 28. A first brush plate 27 is slidably connected to one side of the second brush plate 28. A second fixed rack 34 meshing with the linkage gear 33 is fixedly connected to one side of the first brush plate 27. Second brushes 29 are fixedly connected to the bottoms of the first brush plate 27 and the second brush plate 28. A cleaning nozzle 30 is fixedly connected in the gap between the second brushes 29, which is used to clean the copper strip and clean the second brushes 29 on the opposite side at the same time. Water pipes communicating with the cleaning nozzles 30 are arranged inside the second brush plate 28 and the first brush plate 27. An electromagnetic reversing valve is fixedly connected to the end of the water pipe. A fourth motor 22 is fixedly connected to the outside of the scrubbing pool 9 through a bracket. The output end of the fourth motor 22 is fixedly connected with a driving disc 23. An arc-shaped magnet 25 is fixedly connected to the outside of the driving disc 23. A Hall sensor 24 is fixedly connected to the outside of the bracket corresponding to the position of the arc-shaped magnet 25, which is used to control the alternating water output of the cleaning nozzles 30 of the second brush plate 28 and the first brush plate 27. The output end of the fourth motor 22 is located at a position deviating from the center of the driving disc 23. A driving frame 26 is slidably connected to the outside of the driving disc 23. One end of the driving frame 26 is fixedly connected to the second brush plate 28.

[0040] It should be noted that in this embodiment, the copper strip is pulled towards the central position at the bottom of the brushing pool. Under the action of the guide roller, the copper strip moves upward again, and the copper strip passes through between the two second brushes 29. During this period, the fourth motor 22 drives the driving disk 23 to rotate. The center of the driving disk 23 is offset from the position of the output shaft of the fourth motor 22, so that the rotation of the driving disk 23 is similar to the action of a cam. When the side of the driving disk 23 deviating from the output end of the fourth motor 22 contacts the driving frame 26, under the action of the thrust, the driving frame 26 moves to one side, and the driving frame 26 drives the second brush plate 28 to move to one side on the top of the support slide rail 35. At the same time that the second brush plate 28 moves, the second spring 32 is compressed. When the second brush plate 28 moves, since the first fixed rack 31 is fixedly connected to one end of the support slide rail 35, under its meshing action, the linkage gear 33 rotates. When the linkage gear 33 rotates, it meshes with the second fixed rack 34, so as to drive the first brush plate 27 to slide on one side of the second brush plate 28. When the side of the driving disk 23 close to the output end of the fourth motor 22 contacts the driving frame 26, under the thrust action of the second spring 32, the second brush plate 28 returns to its original position and drives the first brush plate 27 to return to its original position, so as to realize the reciprocating brushing action of the second brush 29 on the outer side of the copper strip. During the brushing period, the arc-shaped magnet 25 on the outer side of the driving disk 23 intermittently contacts the Hall sensor 24. When the arc-shaped magnet 25 contacts the Hall sensor 24, the Hall sensor 24 detects the signal and transmits the signal to the controller, and the controller controls the electromagnetic reversing valve to be energized, so as to realize the intermittent energization of the electromagnetic reversing valve, so that the water alternately enters the first brush plate 27 and the second brush plate 28, so that the cleaning nozzle 30 opposite to the second brush 29 flushes the second brush 29 and flushes the copper strip, so as to ensure that the bristles always maintain a good cleaning effect, and the water flow direction of the cleaning nozzle 30 is constantly changed, reducing the accumulation of dirt, so that the water flow can more evenly cover the entire surface of the brush plate.

[0041] In one embodiment, two drive pipes 38 are rotatably connected inside the air-drying tank. A water-absorbing sponge 39 is fixedly connected to the outer side of the drive pipe 38. The drive pipe 38 is provided with a ventilation opening communicating with the water-absorbing sponge 39. An intake air duct 11 connected to a high-pressure air source is fixedly connected inside the air-drying tank. The intake air duct 11 is located inside the drive pipe 38. A connecting air nozzle 12 for air outlet is provided on the outer side of the intake air duct 11. The connecting air nozzle 12 is slidably connected to the inner wall of the drive pipe 38. One end of the drive pipe 38 is connected by a spur gear. A second motor 10 for driving the spur gear is fixedly connected to the outer side of the air-drying tank. An extrusion arc plate 37 is fixedly connected inside the air-drying tank. The extrusion arc plate 37 is located outside the water-absorbing sponge 39, and the radius of the extrusion arc plate 37 gradually decreases along the direction of rotation of the drive pipe 38. The bottom of the extrusion arc plate 37 is slidably connected to the surface layer of the water-absorbing sponge 39 for squeezing out the water when the water-absorbing sponge 39 rotates. Leakage holes are provided at the bottom of the extrusion arc plate 37. A water receiving funnel 36 is fixedly connected inside the extrusion arc plate 37 and below the extrusion arc plate 37.

[0042] It should be noted that in this embodiment, the copper strip enters the air-drying tank after being cleaned in the ultrasonic cleaning tank and passes between the two electromagnets 19. The water-absorbing sponge 39 adsorbs and scrapes the water on the outer side of the copper strip. Under the action of the timer, the second motor 10 drives the gear on the outer side of the drive pipe 38 to rotate through the gear at its output end, thereby swapping the positions of the water-absorbing sponges 39 on the outer side of the drive pipe 38. The water-absorbing sponge 39 after absorbing water rotates clockwise inside the extrusion arc plate 37. Thus, the radius of the extrusion arc plate 37 gradually decreases clockwise, so that the inner wall of the extrusion arc plate 37 squeezes the water-absorbing sponge 39, causing the water in the water-absorbing sponge 39 to flow downward along the inner wall of the extrusion arc plate 37 and flow into the water receiving funnel 36 through the leakage holes at the bottom of the extrusion arc plate 37. Through the water receiving funnel 36, it is printed into the collection tank. And because the intake air duct 11 is connected to the high-pressure air source, when the connecting air nozzle 12 corresponds to the ventilation opening of the drive pipe 38, high-pressure air enters the water-absorbing sponge 39. The high-pressure air effectively takes away the water in the sponge, reduces the residual water, and enables the water to be quickly dispersed or evaporated. When the drive pipe 38 rotates again, the drive pipe 38 after being squeezed and dried contacts the copper strip again, thereby cleaning and removing water from the copper strip. And air ducts are provided on both sides of the copper strip inside the air-drying tank, and air nozzles corresponding to the copper strip are provided on the outer side of the air ducts, thereby performing a secondary water removal operation on the copper strip through high-pressure air to prevent water from remaining on its surface; the intake air duct is connected to the high-pressure air source. When the connecting air nozzle corresponds to the ventilation opening of the drive pipe, high-pressure air enters the water-absorbing sponge, effectively taking away the water in the sponge, reducing the residual water, and enabling the water to be quickly dispersed or evaporated; air ducts and air nozzles are also provided on both sides of the copper strip inside the air-drying tank. Through high-pressure air, a secondary water removal operation is performed downward on the copper strip to prevent water from remaining on the surface of the copper strip and ensure the drying effect of the copper strip.
