[0033] like Figure 1-9 As shown: One embodiment of the present invention is:

[0035] The driving mechanism 7 includes a box body 71, a driving motor 72 is installed on the top of the box body 71, the output end of the driving motor 72 is connected to the scraper assembly 6, the output end of the driving motor 72 is connected to the baffle assembly 4 through a pulley assembly 73, a first rotating gear 74 is installed on the outer wall of the output end of the driving motor 72 through a one-way bearing, a retractable rotating rod 75 is rotatably connected to the top of the inner cavity of the box body 71, a second rotating gear 76 is fixedly connected to the outer wall of the fixed end of the rotating rod 75, and the second rotating gear 76 is meshed with the first rotating gear 74, a third rotating gear 77 is fixedly connected to the outer wall of the telescopic end of the rotating rod 75, and the outer wall of the rotating shaft of the electrolytic plate assembly 2 is installed through a one-way bearing. A fourth rotating gear 78 is installed, and the fourth rotating gear 78 is meshed and connected with the third rotating gear 77. A torsion spring 79 is sleeved on the outer wall of the rotating shaft of the electrolytic plate assembly 2, and the two ends of the torsion spring 79 are respectively connected to the top of the inner cavity of the box body 71 and the surface of the fourth rotating gear 78. A top rod 64 for causing the rotating rod 75 to contract is installed on the scraper assembly 6, wherein the top rod 64 slides upward with the scraper assembly 6 and gradually contacts the telescopic end of the rotating rod 75, thereby gradually causing the rotating rod 75 to contract, driving the third rotating gear 77 to gradually separate from the fourth rotating gear 78, so that when the fourth rotating gear 78 is reversed, it will not drive the third rotating gear 77 to rotate;

[0036] A floating plate assembly 8 is slidably connected to the top of the electrolysis zone 101, and the floating plate assembly 8 is located between the baffle assembly 4 and the electrolysis plate assembly 2. A ratchet plate 81 that is mutually engaged with the fourth rotating gear 78 is installed at one end of the floating plate assembly 8, and when the floating plate assembly 8 abuts against the bottom of the inner cavity of the electrolytic cell 1, the ratchet plate 81 is separated from the fourth rotating gear 78.

[0037] In this embodiment, the baffle assembly 4 includes a first screw rod 41 connected to the pulley assembly 73, and the outer wall of the first screw rod 41 is threadedly connected to the baffle 42, wherein the rotation of the first screw rod can drive the baffle to slide, thereby realizing the lifting and lowering of the baffle.

[0038] In this embodiment, the floating plate assembly 8 includes a floating plate 82 and a fixed sleeve 83, and one side of the floating plate 82 is slidably connected to the side of the baffle 42, a sliding rod 84 is fixed to the top of the floating plate 82, one end of the sliding rod 84 passes through the top of the electrolytic cell 1 and is installed with an abutment block 85, the fixed sleeve 83 is installed on the top of the electrolytic cell 1 and is sleeved on the outer wall of the sliding rod 84, the outer wall of the fixed sleeve 83 is slidably connected with a ratchet disk 81, the outer wall of the fixed sleeve 83 is sleeved with a spring 86, and the spring 86 is located below the ratchet disk 81, wherein the floating plate gradually descends as the liquid height decreases, thereby driving the sliding rod to slide in the inner cavity of the fixed sleeve, so that the abutment block gradually approaches the ratchet disk, when the floating plate descends to the bottom of the inner cavity of the electrolytic cell (the liquid is completely drained through the circulation pipe assembly), the abutment block presses down the ratchet disk, so that the ratchet disk slides along the fixed sleeve and squeezes the spring, thereby separating the ratchet disk from the fourth rotating gear, so that the fourth rotating gear can rotate freely.

[0039] In the present embodiment, in order to ensure that the floating plate assembly can rise synchronously when the baffle rises, an installation groove 43 is opened on the side of the baffle 42, and a limiting rod 44 is installed between the two opposite ends of the installation groove 43. The outer wall of the limiting rod 44 is slidably connected with a slider 45, and the slider 45 is connected to the floating plate 82. After the floating plate drops to the lowest position, the floating plate can contact the bottom of the installation groove, so that when the baffle assembly slides upward, it can synchronously drive the floating plate assembly to slide upward, and the floating plate can also achieve relative sliding with the baffle through the cooperation of the slider and the limiting rod.

[0040] In this embodiment, the scraper assembly 6 includes a second screw 61 connected to the drive motor 72, and the second screw 61 has an opposite rotation direction to the first screw 41. The outer wall of the second screw 61 is threadedly connected to a threaded sleeve 62, and the bottom of the threaded sleeve 62 is fixedly connected to a scraper 63 that abuts against the surface of the electrolytic plate assembly 2, wherein the rotation of the second screw can drive the threaded sleeve and the scraper to slide up and down, thereby realizing automatic scraping of the surface of the electrolytic plate. At the same time, the rotation direction of the second screw is opposite to that of the first screw, and is driven by the same driving mechanism, so that the baffle and the scraper can slide synchronously in opposite directions, thereby improving the processing efficiency.

[0041] In this embodiment, in order to enable the residue in the scraping area to be discharged quickly, a discharge barrel 9 with a semicircular cross-section is connected to the bottom of the scraping area 102, and the cross-section of the scraper 63 is an arc that matches the discharge barrel 9. A spiral blade 10 is rotatably connected between the opposite ends of the discharge barrel 9. A slag discharge pipe 11 is connected to the bottom of one end of the discharge barrel 9, and an opening that cooperates with the arc-shaped scraper 63 is opened at the top of the scraping area 102, wherein a cylindrical feeding channel can be formed between the arc-shaped scraper and the discharge barrel, and then the conveying action of the spiral blade is cooperated to achieve rapid cleaning of the residue, and in order to allow the scraped metal residue to fall into the discharge barrel, an inclined slope is arranged between the discharge barrel and the bottom of the fixed frame to facilitate material guiding, and the bottom end of the scraper is also correspondingly arranged as a slope, and the opening setting enables the top end of the arc-shaped baffle to pass through, so that the scraper will not affect the rotation of the electrolytic strips.

[0042] In this embodiment, the electrolytic plate assembly 2 includes a fixed frame 21 installed between the side walls of the inner cavity of the electrolytic cell 1, and an electrolytic plate 22 is rotatably connected between the top and bottom of the inner cavity of the fixed frame 21, and the rotating shaft of the electrolytic plate 22 is connected to the fourth rotating gear 78.

[0043] In this embodiment, in order to reduce the area occupied by the electrolytic plate when it rotates, the electrolytic plate 22 is composed of a plurality of independently rotatable electrolytic plate strips 221 arranged side by side, and the opposite sides of the electrolytic plate strips 221 are arc-shaped, and the rotation axis of each electrolytic plate strip 221 passes through the electrolytic cell 1 and is connected through a sprocket assembly 222, and the rotation axis of an electrolytic plate strip 221 is connected to the fourth rotating gear 78, wherein the sprocket assembly can drive each electrolytic plate strip to rotate synchronously in the same direction, and the independent and side-by-side electrolytic plate strips can effectively reduce the area occupied by the electrolytic plate when it is flipped, and in order to facilitate the rotation of the electrolytic plate strips, the opposite ends of a side surface of the electrolytic plate strips close to each other are set as arc surfaces.

[0044] In this embodiment, in order to ensure the sealing between adjacent electrolytic strips, the opposite sides of two adjacent electrolytic strips 221 are respectively provided with mutually matching sealing grooves 223 and sealing strips 224, wherein when the two adjacent electrolytic strips are in contact, the sealing strips can be inserted into the sealing grooves to ensure the sealing.

[0045] In this embodiment, the circulation pipe assembly 5 includes a circulation water pump 51, a circulation pipe 52 and a joint 53. The water inlet and the water outlet of the circulation water pump 51 are both connected to the circulation pipe 52. The free end of the circulation pipe 52 is connected to the joint 53, and a group of joints 53 are located between the baffle assembly 4 and the electrolytic plate assembly 2.

[0046] In this embodiment, a plurality of graphite rods 3 are arranged side by side, and each graphite rod is connected to an external power source in series, and the rotating shaft of each electrolytic strip 221 is connected in series through a collector ring and then connected to the external power source.

[0047] In this embodiment, in order not to affect the flipping of the electrolytic plate assembly 2, the thickness of the floating plate 82 is smaller than the thickness of the top and bottom of the fixed frame 21. At the same time, when the floating plate 82 drops to the lowest position, the floating plate 82 is below the bottom of the fixed frame 21.

[0048] In this embodiment, the electrolytic cell 1 is installed on a frame 12 for use.

[0049] The specific working process of this embodiment is as follows:

[0050] When the etching solution (taking etching solution rich in copper ions as an example) is electrolyzed, the filtered etching solution is injected into the electrolysis zone 101 of the electrolytic cell 1, and then the external power supply and the circulating water pump 51 are started. The external power supply is turned on to form a conductive loop between each electrolytic strip 221 (made of copper), the graphite rod 3 and the etching solution, so that the metal ions in the etching solution can undergo a reduction reaction near the electrolytic strip 221 to form copper and adhere to the surface of the electrolytic strip 221. At the same time, the circulating water pump 51 generates a circulating flow through the cooperation of the circulating pipe 52 and the joint 53, thereby improving the electrolysis efficiency.

[0051] After a period of electrolysis, the external power supply between the electrolytic plate assembly 2 and the graphite rod 3 is turned off, and the drive motor 72 is started in the forward direction. The drive motor 72 drives the first screw 41 and the second screw 61 to rotate synchronously through the pulley assembly 73;

[0052] The first screw 41 rotates forward to drive the baffle 42 to descend and abut against the bottom of the electrolytic cell 1, so that a closed space is formed between the baffle 42 and the electrolytic plate assembly 2. When the baffle 42 descends, the floating plate 82 gradually descends with the baffle 42 and reaches the liquid surface. Due to the buoyancy, the baffle 42 and the floating plate 82 slide relative to each other, and the circulating water pump 51 gradually pumps out the liquid in the closed space, so that the floating plate 82 can gradually descend.

[0053] The second screw rod 61 rotates forward to drive the threaded sleeve 62 and the scraper 63 to rise, and when the baffle plate 42 slides to the lowest position, the scraper 63 slides to the highest position, and at the same time, the rotation of the second screw rod 61 can drive the first rotating gear 74 to rotate, and the first rotating gear 74 drives the second rotating gear 76, the rotating rod 75 and the third rotating gear 77 to rotate, thereby driving the fourth rotating gear 78 to rotate through the third rotating gear 77, and because the fourth rotating gear 78 is connected to the rotating shaft of the electrolysis strip 221 through a one-way bearing, the fourth rotating gear 78 generates idling (will not drive the electrolysis strip 221 to rotate). The release strip 221 rotates), the fourth rotating gear 78 rotates to drive the torsion spring 79 to twist, and the setting of the pawl plate 81 makes the fourth rotating gear 78 can only rotate in one direction (that is, when the pawl plate 81 is engaged with the fourth rotating gear 78, the fourth rotating gear 78 can only rotate in the direction of storing force of the torsion spring 79), and as the scraper 63 gradually rises, the top rod 64 gradually contacts the telescopic end of the rotating rod 75 and squeezes the rotating rod 75 to contract, so that the third rotating gear 77 disengages from the fourth rotating gear 78, and after the scraper 63 and the baffle 42 are all in place, the drive motor 72 is turned off.

[0054] Then, the floating plate 82 gradually slides downward as the liquid level drops, thereby driving the sliding rod 84 and the abutment block 85 to gradually descend until the liquid is completely drained, and the floating plate 82 descends to the lowest position (sliding to the bottom of the installation groove 43). At this time, the abutment block 85 contacts the pawl plate 81 and pushes the pawl plate 81 to slide downward along the fixed sleeve 83, so that the pawl plate 81 is disengaged from the fourth rotating gear 78. At this time, the fourth rotating gear 78 is reversed under the action of the restoring force of the torsion spring 79. At this time, the rotation axis of the electrolytic strip 221 can be driven to rotate through the cooperation of the one-way bearing, and each electrolytic strip 221 is rotated 180 degrees in the same direction under the action of the sprocket assembly 222, so that the two sides of the electrolytic strip 221 are turned over, and the side with metal attached is turned over to the scraping area 102. In addition, since the third rotating gear 77 is disengaged from the fourth rotating gear 78, the reverse rotation of the fourth rotating gear 78 will not drive the third rotating gear 77 to rotate;

[0055] After the flipping is completed, the drive motor 72 is started in the reverse direction, and the drive motor 72 drives the first screw 41 and the second screw 61 to rotate in the opposite direction, respectively driving the baffle 42 to rise and the scraper 63 to descend. At the same time, since the first rotating gear 74 and the drive motor 72 are installed through a one-way bearing, the reverse rotation of the drive motor 72 will not drive the first rotating gear 74 to rotate. As the baffle 42 gradually rises, the liquid contacts the electrolytic strip 221 again, and the external power is turned on for electrolysis again. The descent of the scraper 63 drives the push rod 64 to descend, so that the rotating rod 75 returns to its original position under the gravity of the third rotating gear 77, and the scraper 63 descends to scrape the metal on the surface of the electrolytic strip 221 and drops it into the discharge barrel 9. After the scraper 63 descends to the lowest position, the drive motor 72 is turned off to complete the scraping treatment of the electrolytic strip 221. In this way, the electrolytic plate assembly 2 is scraped and discharged irregularly or regularly, reducing the cleaning downtime, improving the electrolysis efficiency, and no large amount of etching liquid will flow out during the treatment process.

[0056] During the rising process of the baffle plate 42 , the floating plate 82 can be synchronously driven to rise, so that the floating plate 82 rises back to the highest position. At this time, the pawl plate 81 returns to its original position under the action of the restoring force of the spring 86 and re-engages with the fourth rotating gear 78 .

[0057] After the scraper 63 descends to the lowest position, a cylinder is formed between the scraper 63 and the discharge cylinder 9 , and then the motor of the spiral blade 10 is started to drive the spiral blade 10 to rotate to transport the residue and discharge it from the residue discharge pipe 11 .

[0058] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
