Description

Technical Field

[0001] The invention belongs to the technical field of electronic aluminum foil, and in particular relates to electronic aluminum foil pre-treatment equipment and technology. Background Art

[0002] Electronic aluminum foil is a kind of aluminum foil made by subjecting high-purity aluminum ingots to a series of rolling, cleaning and cutting processes. It is a key raw material for the production of aluminum electrolytic capacitors. The thickness is generally 125-130 microns. After the electronic aluminum foil is formed, it needs to go through the steps of pre-treatment, first cleaning, first electrolysis, second cleaning, second electrolysis, third cleaning, post-treatment, fourth cleaning, drying, curling and testing in sequence; the purpose of the pre-treatment is to remove oil and oxide film on the surface of the electronic aluminum foil. The pre-treatment method is to soak the electronic aluminum foil in a treatment liquid at a certain temperature for a period of time.

[0003] In order to extend the time that the electronic aluminum foil stays in the treatment liquid, a plurality of reversing rollers are usually arranged in the water tank, and the aluminum foil passes through each reversing roller in turn to increase the path of the aluminum foil in the treatment liquid, thereby increasing the treatment time. However, this type of process has the following problems in the actual processing: (1) The oil stains and oxide film on the surface of the electronic aluminum foil fall off after contact with the treatment liquid, and form fine flocs floating in the treatment liquid. Some of the flocs will adhere to the surface of the reversing roller to form solid matter. During the contact between the electronic aluminum foil and the reversing roller, such solid matter directly contacts the surface of the electronic aluminum foil, which easily leaves scratches on the surface of the electronic aluminum foil, affecting the surface quality of the electronic aluminum foil; (2) The treatment liquid and the electronic aluminum foil only have relative flow along the direction of the electronic aluminum foil conveying, resulting in insufficient contact between the treatment liquid and the surface of the electronic aluminum foil, making it difficult to effectively remove the oil stains and oxide film on the surface of the electronic aluminum foil. Summary of the invention

[0008] As a preferred technical solution of the present invention, the interior of the reversing roller is in a horizontal funnel shape, the water outlet is located in the middle section of the reversing roller, and the inner diameters of the two ends of the reversing roller are larger than the inner diameter of the middle section.

[0009] As a preferred technical solution of the present invention, a number of rotating rods are evenly installed in the water outlet trough along its length direction, each rotating rod is rotatably installed with two mutually symmetrical rotating shafts, a rotating plate is fixedly installed on the rotating shaft, a counterweight block is slidably installed at the edge of the rotating plate, and stop blocks corresponding to the position of the counterweight block are fixedly installed at both ends of the edge of the rotating plate.

[0010] As a preferred technical solution of the present invention, a slot is provided on the end face of the reversing roller, the bracket slides in cooperation with the slot, a plurality of mushroom buckles are fixedly mounted on the bracket, and a card slot cooperating with the mushroom buckles is provided on the end face of the slot at a position corresponding to the mushroom buckles.

[0011] As a preferred technical solution of the present invention, a retaining ring that fits with the annular frame is fixedly installed on the inner circumferential surface of the water outlet trough, and a plurality of threaded rods that penetrate the annular frame are installed on the annular frame by threaded cooperation. The plurality of threaded rods are evenly arranged in a ring shape on the annular frame, and a thread groove is opened on the retaining ring corresponding to the position of each threaded rod. A gear column is fixedly installed at the end of the threaded rod away from the thread groove, and an adjusting gear ring that meshes with the gear column is rotatably installed on the end surface of the annular frame, and a shift rod is fixedly installed on the end surface of the adjusting gear ring.

[0012] As a preferred technical solution of the present invention, a water retaining plate is fixedly installed in the middle position of the filter screen, a pressure plate corresponding to the position of the water retaining plate is fixedly installed on the inner side of the retaining ring through a connecting rod, a guide rod that penetrates the water retaining plate and slides with the water retaining plate is fixedly installed on the pressure plate, and a telescopic spring sleeved on the guide rod is installed between the water retaining plate and the pressure plate; a plurality of arc-shaped water retaining strips are evenly fixedly installed along the circumferential direction on the end surface of the water retaining plate facing the outside of the reversing roller.

[0013] The present invention provides an electronic aluminum foil pretreatment process, which is completed by using the above-mentioned electronic aluminum foil pretreatment equipment, and specifically includes the following steps:

[0014] Step 1: Install the aluminum foil: Lay the aluminum foil on one of the tension rollers, then pass the aluminum foil through each reversing roller from back to front, and finally lay the aluminum foil on the other tension roller;

[0015] Step 2: Liquid injection and heating: inject the treatment liquid into the water tank through the liquid inlet pipe until the treatment liquid submerges all the reversing rollers, and energize the heating wire to heat the treatment liquid in the water tank;

[0016] Step 3: Directional conveying: Turn on each drive motor and convey the aluminum foil from back to front through an external conveying device. The aluminum foil contacts the treatment liquid in the water tank, and the oil and oxide film on the surface of the aluminum foil are removed by the treatment liquid.

[0017] The present invention has at least the following beneficial effects: (1) During the pre-treatment of the electronic aluminum foil by the present invention, the treatment liquid in the water tank is sucked into the high-speed rotating reversing roller from the outside of the reversing roller by the blades, and then sprayed out from the water outlet tank under the combined action of centrifugal force and water pressure and acts on the surface of the electronic aluminum foil around the reversing roller. After being acted upon by water, the electronic aluminum foil will not contact the surface of the reversing roller, thereby avoiding the situation where the electronic aluminum foil is scratched by solid matter on the surface of the reversing roller.

[0018] (2) The reversing roller of the present invention is internally installed with a detachable annular frame and a filter screen, and the treatment liquid entering the reversing roller is filtered through the filter screen to remove fine flocs contained in the treatment liquid, so as to prevent the flocs from acting on the surface of the electronic aluminum foil under the drive of the high-speed water flow and causing scratches on the surface of the electronic aluminum foil; when the treatment liquid passes through the filter screen, most of the treatment liquid can pass through the filter screen, and a small part of the treatment liquid will form an unstable backflow. The force of the treatment liquid on the water retaining plate, the force of the backflow on the water retaining strip, and the elastic force of the telescopic spring cooperate with each other, so that the water retaining plate continues to move irregularly back and forth along the guide rod, thereby driving the filter screen to shake back and forth, thereby preventing the flocs from clogging the filter screen.

[0019] (3) During the process of the treatment liquid being sprayed out from the inside of the reversing roller through the water outlet trough, the reversing roller is continuously rotating at a high speed, and the rotating rod, rotating shaft, rotating plate, counterweight block and stop block inside the water outlet trough rotate synchronously at a high speed with the reversing roller. Since the counterweight block slides irregularly on the surface of the rotating plate under the action of gravity, the rotating plate and the rotating shaft will produce irregular rotation. The high-speed flowing treatment liquid in the water outlet trough acts on the rotating plate and also drives the rotating rod to rotate irregularly, so that the treatment liquid sprayed out of the water outlet trough forms irregular turbulence. The turbulence acts on the surface of the electronic aluminum foil around the reversing roller to remove oil stains and oxide films from all directions, thereby improving the effect of removing oil stains and oxide films. In the present invention, the treatment liquid on both sides of the reversing roller enters the inside of the reversing roller and then sprays out from the reversing roller. This process promotes the convection of the treatment liquid in the water trough, avoids the situation where part of the treatment liquid is in contact with the electronic aluminum foil for a long time, and further improves the effect of the treatment liquid on removing oil stains and oxide films.

DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0031] like Figure 1 As shown, this embodiment provides an electronic aluminum foil pre-treatment device, including a water tank 1, and tensioning rollers 2 are rotatably installed on the tops of the front and rear end plates of the water tank 1, and the two tensioning rollers 2 are parallel to each other; a plurality of evenly distributed heating wires 13 are fixedly installed on the inner sides of the front and rear end plates of the water tank 1, and a liquid inlet pipe 14 connected to the interior of the water tank 1 is arranged on the front end plate of the water tank 1, and a liquid outlet pipe 15 connected to the interior of the water tank 1 is arranged on the bottom of the rear end plate of the water tank 1; after the liquid outlet pipe 15 is closed, the treatment liquid is injected into the water tank 1 through the liquid inlet pipe 14, and then the heating wire 13 is energized, so that the treatment liquid in the water tank 1 is heated by the heating wire 13.

[0032] like Figure 1 and Figure 2 As shown, a plurality of reversing rollers 3 parallel to the tensioning roller 2 are rotatably installed inside the water tank 1 through a limiting frame, and the plurality of reversing rollers 3 are staggered in two layers; driven gear rings 4 are fixedly sleeved at both ends of the reversing rollers 3, and a driving motor 5 is installed at a position corresponding to each driven gear ring 4 on the outer wall of the water tank 1, and the output shaft of the driving motor 5 passes through the side wall of the water tank 1 and is fixedly installed with a driving gear 6 meshing with the corresponding driven gear ring 4; before the processing starts, the aluminum foil is first manually fitted with a tensioning roller 2, and then passes through each reversing roller 3 in turn and then fits with another tensioning roller 2; after the driving gear 6 is turned on, the driven gear ring 4 and the reversing roller 3 are driven to rotate at a high speed through the driving gear 6.

[0033] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the reversing roller 3 is a hollow structure and brackets 7 are installed on the inner circumference of the reversing roller 3 near both ends. A slot 302 is provided on the end surface of the reversing roller 3. The bracket 7 slides with the slot 302. A plurality of mushroom buckles 24 are fixedly installed on the bracket 7. A slot 303 matching with the mushroom buckle 24 is provided on the end surface of the slot 302 at a position corresponding to the mushroom buckle 24; a fixed shaft 8 coinciding with the axis of the reversing roller 3 is fixedly installed on the bracket 7, and a plurality of blades 9 are evenly fixedly installed on the fixed shaft 8 along its circumference; a plurality of water outlet grooves 301 penetrating the reversing roller 3 are evenly provided on the reversing roller 3 along its circumference, and the water outlet grooves 301 are strip-shaped and parallel to the axis of the reversing roller 3; The interior of the roller 3 is in the shape of a horizontal funnel, the water outlet groove 301 is located in the middle section of the reversing roller 3 and the inner diameters of the two ends of the reversing roller 3 are larger than the inner diameter of the middle section; push plates 10 are fixedly installed on the inner circumferential surface of the reversing roller 3 and located between two adjacent water outlet grooves 301, and the two ends of the push plates 10 are flush with the two ends of the water outlet groove 301; a number of rotating rods 19 are evenly installed in the water outlet groove 301 along its length direction, and each rotating rod 19 is rotatably installed with two mutually symmetrical rotating shafts 20, and a rotating plate 21 is fixedly installed on the rotating shaft 20, and a counterweight block 22 is slidably installed at the edge of the rotating plate 21, and stoppers 23 corresponding to the position of the counterweight block 22 are fixedly installed at both ends of the edge of the rotating plate 21.

[0034] During the high-speed rotation of the reversing roller 3, the bracket 7 drives the fixed shaft 8 and the blades 9 to rotate at a high speed, and the care liquid on the outside of the reversing roller 3 is sucked into the reversing roller 3 from both ends by the blades 9. On the one hand, the water pressure inside the reversing roller 3 increases, and on the other hand, during the high-speed rotation of the reversing roller 3, the push plate 10 pushes the treatment liquid in the reversing roller 3 to rotate synchronously, and the treatment liquid will be affected by the centrifugal force, so that the treatment liquid is sprayed out from each water outlet trough 301 under the combined action of water pressure and centrifugal force; because the counterweight block 22 slides irregularly at the edge of the rotating plate 21 under the action of gravity, the rotating plate 21, the rotating shaft 20 and the rotating rod 19 rotate irregularly while following the revolution of the reversing roller 3, and the treatment liquid passing through the water outlet trough 301 is guided by the rotating plate 21 It is sprayed out from the water outlet trough 301 in an irregular state, so that a layer of turbulence is formed on the outer surface of the reversing roller 3. The turbulent flow contacts the electronic aluminum foil near the reversing roller 3. On the one hand, it avoids the direct contact between the electronic aluminum foil and the surface of the reversing roller 3. On the other hand, it cleans the surface of the electronic aluminum foil from all directions, which not only avoids the scratches on the surface of the electronic aluminum foil, but also improves the effect of removing oil and oxide film on the surface of the electronic aluminum foil. It should be noted that since the interior of the reversing roller 3 is in the shape of a horizontal funnel, the flow rate of the processing liquid in the middle section of the reversing roller 3 is higher than the flow rate of the processing liquid at both ends of the reversing roller 3, thereby increasing the speed of the processing liquid spraying out of the water outlet trough 301, and further improving the effect of the processing liquid on removing oil and oxide film on the surface of the electronic aluminum foil.

[0035] like Figure 5 and Figure 7 As shown, an annular frame 11 is installed at positions near both ends of the inner circumference of the water outlet trough 301, and a filter screen 12 is fixedly installed on the annular frame 11; a retaining ring 25 that fits the annular frame 11 is fixedly installed on the inner circumference of the water outlet trough 301, and a plurality of threaded rods 26 that penetrate the annular frame 11 are installed on the annular frame 11 by threaded matching. The plurality of threaded rods 26 are evenly arranged on the annular frame 11 in an annular shape, and a thread groove 2501 is opened on the retaining ring 25 at a position corresponding to each threaded rod 26, and a gear column 27 is fixedly installed on the end of the threaded rod 26 away from the thread groove 2501, and the end surface of the annular frame 11 An adjusting gear ring 28 meshing with the gear column 27 is rotatably installed on the upper side, and a lever 29 is fixedly installed on the end surface of the adjusting gear ring 28; a water retaining plate 30 is fixedly installed in the middle position of the filter screen 12, and a pressure plate 31 corresponding to the position of the water retaining plate 30 is fixedly installed on the inner side of the retaining ring 25 through a connecting rod, and a guide rod 32 that penetrates the water retaining plate 30 and slides with the water retaining plate 30 is fixedly installed on the pressure plate 31, and a telescopic spring 33 sleeved on the guide rod 32 is installed between the water retaining plate 30 and the pressure plate 31; a plurality of arc-shaped water retaining strips 34 are evenly fixedly installed along the circumferential direction on the end surface of the water retaining plate 30 facing the outside of the reversing roller 3.

[0036] The treated liquid that enters the reversing roller 3 partially passes through the filter screen 12, and the other part forms a backflow. Under the filtering effect of the treated liquid that passes through the filter screen 12, fine flocs are adsorbed on the surface of the filter screen 12; the part of the treated liquid that flows back acts on the water retaining bar 34, and this force causes the water retaining bar 34 to drive the water retaining plate 30 to move along the guide rod 32 away from the pressure plate 31. Since the backflow is in an unstable state, the force of the backflow on the water retaining bar 34 is also unstable. When the force of the backflow on the water retaining bar 34 is reduced, the force of the treated liquid on the water retaining plate 30 causes the water retaining plate 30 to move toward the pressure plate 31, and the telescopic spring 33 is compressed by the thrust of the water retaining plate 30; when the force of the backflow on the water retaining bar 34 increases again, the water retaining plate 30 is under the force of the water retaining bar 34 and the telescopic spring 33. Under the action of the resilience of the compression spring 33, the water retaining plate 30 moves away from the pressure plate 31 along the guide rod 32 again; during the irregular reciprocating movement of the water retaining plate 30 along the guide rod 32, the filter screen 12 is driven to form a shaking effect, and the floccules will be separated from the filter screen 12 in the shaking state, thereby avoiding the situation that the floccules are always adsorbed on the filter screen 12 and affect the smooth passage of the treated liquid through the filter screen 12; after the processing is completed, when the filter screen 12 needs to be cleaned, it is only necessary to manually pull out the bracket 7, and then turn the lever 29 to drive the adjusting gear ring 28 to rotate, and the adjusting gear ring 28 drives the gear column 27 and the threaded rod 26 to rotate. During the rotation of the threaded rod 26, it withdraws from the threaded groove 2501, thereby releasing the connection between the annular frame 11 and the retaining ring 25, and finally the annular frame 11 can be taken out.

[0037] like Figure 1 and Figure 6 As shown, a crossbeam 16 is fixedly installed between the left and right end plates of the water tank 1 at the position corresponding to each lower-layer reversing roller 3, and a first sealing plate 17 is fixedly installed on the crossbeam 16 through a connecting plate. The first sealing plate 17 is an arc-shaped plate and fits with the surface of the corresponding lower-layer reversing roller 3; a second sealing plate 18 is fixedly installed on the bottom surface of the water tank 1 at the position corresponding to each upper-layer reversing roller 3 through a connecting plate, and the second sealing plate 18 is an arc-shaped plate and fits with the surface of the corresponding upper-layer reversing roller 3; the water outlet 301 on the upper part of the reversing roller 3 is sealed by the first sealing plate 17 and the second sealing plate 18, and only the water outlet 301 corresponding to the position of the electronic aluminum foil is retained, thereby further improving the speed of the treatment liquid spraying out of the water outlet 301, and improving the effect of the treatment liquid on removing oil stains and oxide films on the surface of the electronic aluminum foil.

[0038] like Figure 8 As shown, this embodiment also provides an electronic aluminum foil pre-treatment process, which is completed by using the above-mentioned electronic aluminum foil pre-treatment equipment, and specifically includes the following steps:

[0039] Step 1: Install the aluminum foil: Lay the aluminum foil on one of the tension rollers 2, then pass the aluminum foil through each reversing roller 3 from back to front, and finally lay the aluminum foil on the other tension roller 2;

[0040] Step 2: Liquid injection and heating: inject the treatment liquid into the water tank 1 through the liquid inlet pipe 14 until the treatment liquid submerges all the reversing rollers 3, and energize the heating wire 13 to heat the treatment liquid in the water tank 1;

[0041] Step 3, directional conveying: turn on each driving motor 5, and convey the aluminum foil from back to front through an external conveying device. The reversing roller 3 rotates at a high speed, and the internal processing liquid is sprayed out from the outlet tank 301, forming an irregular turbulent layer on the surface of the reversing roller 3. The electronic aluminum foil contacts the turbulent layer on the surface of the reversing roller 3, and the oil stains and oxide film on the surface of the electronic aluminum foil are removed by the processing liquid.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
