Description

Technical Field

[0001] The present invention relates to the field of equipment used in electrolysis or electrophoresis processes, and in particular to an equipment for recovering copper produced by solution electrolysis. Background Art

[0002] Black copper powder is a material with excellent performance and wide application. Black copper powder has a fine particle size and a large surface area, which makes it have a high specific surface area and activity. Black copper powder shows high purity and controllability in chemistry, and has good electrical conductivity, thermal conductivity and chemical stability. Therefore, black copper powder is widely used in many fields. At present, the main production method of black copper powder is through electrolysis of copper-containing solution and precipitation at the cathode.

[0003] Therefore, the black copper powder is attached to the cathode. The traditional method is for workers to manually scrape off the black copper powder, which is inefficient and has a negative impact on the health of workers. Some automatic scraping equipment uses a complete blade to scrape off one plate, but does not consider the uneven distribution of the black copper powder adhesion at different positions on the same plate. Some plates are not flat when they are selected.

[0004] For example, the "automatic scraping device for black copper plate" in announcement number CN220579419U is equipped with a plurality of scraping plates, and the black copper powder on the electrode plate can be scraped off by adjusting the angle through the tension rod. However, when adjusting the angle of the scraping plate, all the scraping plates are adjusted at the same time, resulting in that when scraping off the black copper powder on a piece of electrode plate, the angle of the scraping plate needs to be adjusted at least twice, or the electrode plate needs to be rotated at least once, which is inefficient and lacks a compensation force mechanism, and cannot guarantee the scraping effect when there are stubborn black copper powder blocks attached to the electrode plate. Summary of the invention

DETAILED DESCRIPTION

[0038] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0039] Embodiment 1: like Figures 1 to 14 As shown, the present invention discloses a device for scraping off plate surface attachments, comprising a blade set 1 and an electrode plate 2, wherein the blade set 1 is fixedly connected to one side of a blade set mounting long plate 6 at intervals, and a blade set driving component 61 is provided on the other side of the blade set mounting long plate 6, and the blade set 1 is transmission-connected to the blade set driving component 61. The blade set 1 in the device for scraping off plate surface attachments of the present invention can adjust the number of blade sets 1 installed and placed in the device according to the number of electrode plates 2 to be scraped off and the need to scrape off the black copper powder attached to the electrode plates 2.

[0040] The blade assembly 1 is composed of a frame 16 and blades, and the frame 16 is in a relatively flat rectangular shape. A scraper assembly consisting of a plurality of long blades 11 and short blades 12 alternating with each other can be placed within the capacity of the frame 16, and the bottom of the frame 16 is connected to a long plate. Two shafts are provided from top to bottom near the lower part of the frame 16. The upper shaft is the drive shaft 14, and the lower shaft is the clamping member tensioning shaft 17. The projections of the axes of the drive shaft 14 and the clamping member tensioning shaft 17 can be overlapped or staggered on the plane, which has little effect on the scraping effect of the blade assembly 1 on the electrode plate 2.

[0041] The frame 16 is designed with a semi-enclosed structure, which provides a stable support and provides a mounting position for the long blade 11 and the short blade 12. The long blade 11 and the short blade 12 are installed alternately in the frame 16 and fixed on the drive shaft 14. The drive shaft 14 uniformly controls the angle between the scraper assembly consisting of a plurality of alternating long blades 11 and short blades 12 and the electrode plate 2 during the scraping operation. The installation of the drive shaft 14 on the frame. The drive shaft 14 is relatively long, and the installation position passes through the frame 16, and two relatively long sections extend outward from the through position on both sides of the frame 16.

[0042] Below the driving shaft 14, a clamping member tensioning shaft 17 is arranged parallel to the driving shaft 14. The main function of the clamping member tensioning shaft 17 is to limit the movement of the support rod. The clamping member tensioning shaft 17 limits the elastic clamping member 13 installed on the driving shaft 14. By limiting the movement of the elastic clamping member 13, the deformation of the elastic clamping member 13 is increased, and the elastic force of the elastic clamping member 13 is increased. The downward pressure applied by the elastic clamping member 13 to the long blade 11 and the short blade 12 can make the long blade 11 and the short blade 12 more firmly pressed on the plate surface of the pole plate 2 when in contact with the pole plate 2, thereby improving the effect of scraping off the black copper powder on the pole plate 2. It is ensured that the long blade 11 and the short blade 12 will not easily jump during the scraping process, resulting in poor panel scraping effect of the pole plate 2.

[0043] Because the black copper powder is a metal product precipitated from an acidic solution, it is highly corrosive before cleaning, and the frame 16, the long blade 11, and the corresponding short blade 12 need to be in contact with the black copper powder for a long time during operation, and are easily corroded. In order to enhance the practicality and durability of the blade set 1. The frame 16 can be made of stainless steel, or electroplated on the surface of the frame 16 so that a corrosion-resistant layer is attached to the surface of the frame 16.

[0044] Although the frame 16 is less impacted than the long blade 11 and the short blade 12 when scraping the panel of the electrode plate 2, it will also have more contact and friction with the black copper powder, and the electroplating layer is easily corroded, resulting in protection failure. Therefore, compared with surface treatment of the frame 16, it is more preferable to select stainless steel material to manufacture the frame 16. Using stainless steel is not only lower in cost, but also conducive to mass production and simplified production process.

[0045] Because the long blade 11 and the short blade 12 are in direct contact with the pole plate 2 and produce friction, the working environment of the long blade 11 and the short blade 12 is more severe, and the material requirements of the blade are higher. On the one hand, the blade needs to scrape off the black copper powder attached to the panel of the pole plate 2, which requires the long blade 11 and the short blade 12 to have a higher hardness. On the other hand, the long blade 11 and the short blade 12 need to be in contact with the highly corrosive black copper powder for a long time, and the corrosion resistance of the long blade 11 and the short blade 12 is also required to be higher. Stainless steel with good hardness and corrosion resistance can be selected for production.

[0046] In the blade set 1, the long blade 11 and the short blade 12 are different in length and structure at the blade head, but have the same blade width. In order to drive the movement of the flat long blade 11 and the short blade 12, a blade fixing seat 15 is fixedly installed on the long blade 11 and the short blade 12 and then fixed on the driving shaft 14. The connection part between the blade fixing seat 15 and the long blade 11 and the short blade 12 uses a flat plate structure, which can make the connection between the blade fixing seat 15 and the long blade 11 and the short blade 12 more firm and reliable during the installation process. Two long blade mounting holes 112 are provided at the lower part of the long blade 11 and two short blade mounting holes 122 are provided at the lower part of the short blade 12, which are matched with the blade mounting holes on the blade fixing seat 15.

[0047] The blade fixing seat 15 is connected to the drive shaft 14 through a tubular structure provided on the blade fixing seat 15. Compared with the conventional integrated shaft-tube connection method, in the present invention, a piece of the blade fixing seat 15 and the drive shaft 14 is connected to the tubular structure of the blade fixing seat 15 and is cut off from the middle of the tubular structure, only completely cutting off the tubular structure, and not completely cutting off the flat plate structure connecting the blade fixing seat 15 and the blade. At the position where the tubular structure is cut off, the width of the cut-off gap can accommodate the installation of the elastic pressure piece 13. And the elastic pressure piece 13 is not given too much movement margin on the axis of the drive shaft 14, reducing the sliding of the elastic pressure piece 13 on the drive shaft 14, reducing the noise and wear of the equipment operation.

[0048] When the blade fixing seat 15 and the elastic pressing member 13 are installed on the driving shaft 14, the elastic pressing member 13 needs to be placed in the gap at the cut-off portion of the blade fixing seat 15 before the blade fixing seat 15 and the elastic pressing member 13 are sequentially sleeved on the driving shaft 14. Accordingly, when the blade fixing seat 15 and the elastic pressing member 13 are installed on the driving shaft 14, the long blade 11 or the short blade 12 can be selectively installed on the blade fixing seat 15.

[0049] The elastic pressing member 13 is a coil-shaped structure, which is a torsion spring structure. The tubular structure in the middle of the elastic pressing member 13 cooperates with the driving shaft 14 and is sleeved on the driving shaft 14. When the driving shaft 14 rotates, the blade fixing seat 15 can be driven to rotate synchronously, but the elastic pressing member 13 will not rotate with the driving shaft 14.

[0050] Because the two ends of the elastic pressing member 13 extend outwardly to form a blade contact section 132 and a tension section 131. The blade contact section 132 is in close contact with the surface of the blade, and the position where the blade contact section 132 contacts the long blade 11 or the short blade 12 is on the back side relative to the contact surface of the long blade 11 and the short blade 12 with the blade fixing seat 15, so that downward pressure can be applied to the blade. The contact position of the blade contact section 132 with the blade is located near the lower part of the blade and at the center of the blade surface.

[0051] On the one hand, it can further ensure the close connection between the blade and the blade fixing seat 15. On the other hand, as the blade is lifted, the blade contact section 132 will be continuously lifted, while the main structure of the elastic pressing member 13 will not rotate, so that the deformation angle of the elastic pressing member 13 is continuously increased, further increasing the pressure applied by the blade contact section 132 to the blade, and increasing the pressure of the blade on the electrode plate 2 when scraping the electrode plate 2, so that the blade and the surface of the electrode plate 2 are in contact more firmly and more closely, and the scraping effect of the black copper powder on the electrode plate 2 is better.

[0052] A clamping member tensioning shaft 17 is provided below the driving shaft 14, and the clamping member tensioning shaft 17 is a fixed limiting shaft of the elastic clamping member 13. The clamping member tensioning shaft 17 limits the elastic clamping member 13 from following the movement of the driving shaft 14 and rotating. Another extension section of the elastic clamping member 13 is a tensioning section 131, and the tensioning section 131 cooperates with the clamping member tensioning shaft 17 to limit the rotation of the elastic clamping member 13.

[0053] The clamping member tensioning shaft 17 is fixedly mounted on the frame 16 and is not driven to rotate, but can be fixedly mounted or rotatably mounted on the frame 16. The tensioning section 131 is hook-shaped or spoon-shaped. The length of the tensioning section 131 is greater than the diameter of the clamping member tensioning shaft 17, and the end of the tensioning section 131 is located below the clamping member tensioning shaft 17. The tensioning section 13 can cover most of the cross-section of the clamping member tensioning shaft 17. There is a turning point below the tensioning section 13, and the turning angle is greater than or equal to ninety degrees, which is a right angle or an obtuse angle.

[0054] The turning point at the lower end of the tensioning section 131 can better hook the tensioning shaft 17 of the pressing member, and can ensure that during the rotation of the driving shaft 14, the tensioning section 131 can firmly hook the tensioning shaft 17 of the pressing member, so that the deformation of the elastic pressing member 13 increases continuously with the rotation of the driving shaft 14, thereby increasing the pressure that can be applied by the elastic pressing member 13, and ensuring the scraping effect.

[0055] Because each of the long blades 11 and the short blades 12 is independently connected to a blade fixing seat 15, the rotation of the long blades 11 and the short blades 12 needs to follow the blade fixing seat 15 installed with the long blades 11 and the short blades 12. In order to drive the blade fixing seat 15 to rotate with the driving shaft 14. Therefore, at the location of the tubular structure of each blade fixing seat 15 and the shaft section of the driving shaft 14 that matches, a driving rod 141 is provided on the driving shaft 14. The driving rod 141 is in the shape of a threaded rod, is installed on the driving shaft 14, and has a shaft section extending outward.

[0056] Correspondingly, at the position on the blade fixing seat 15 that matches the driving rod 141, a driving rod movable groove 151 is provided on the blade fixing seat 15. The driving rod movable groove 151 is an opening opened on the tubular structure of the blade fixing seat 15. On one blade fixing seat 15, at least one of the two tubular structures is provided with one driving rod movable groove 151. The arc range of the driving shaft movable groove is preferably between 90° and 100°, and can be slightly larger than 90°.

[0057] like Fig. 9 As shown, when the drive shaft 14 needs to push the blade fixing seat 15 to lift up, the drive rod 141 will press against the side of the drive rod movable slot 151 that is closer to the blade, and the drive shaft 14 drives the drive rod 141 to rotate counterclockwise, thereby pushing the blade fixing seat 15 to rotate counterclockwise and be lifted up. To put down the blade fixing seat 15, it is only necessary to drive the drive shaft 14 clockwise. When the drive rod 141 no longer presses against the blade fixing seat 15, the blade fixing seat 15 and the blade are naturally put down under the action of gravity and pressing force, and contact the drive rod 141.

[0058] When the blade holder 15 rotates to an excessively large angle and the center line of the blade holder 15 crosses the other side of the vertical plane, although the blade holder 15 will maintain a counterclockwise rotation due to gravity, the deformation of the elastic clamp 13 is relatively large at this time, and a force perpendicular to the contact surface and in the direction that passes through the blade holder 15 is always applied to the blade and the blade holder 15, and the magnitude of the force is relatively large, which can overcome a large part of the component of the blade holder 15 and the blade's gravity in the tangential direction of the movement, thereby preventing or even overcoming the tendency of the blade holder 15 to continue to rotate counterclockwise. It should be noted that the expression of counterclockwise rotation in this paragraph and the previous paragraph is based on Fig. 9The blade placement view in FIG. 1 is described for the sake of convenience, and does not limit the rotation direction of the present invention, but only defines the counterclockwise rotation according to the viewing angle. If the blade assembly 1 is mirrored, the blade fixing seat 15 can also be raised by rotating clockwise, and lowered by rotating counterclockwise.

[0059] In normal operation, the force that the elastic pressing member 13 always applies to the blade in a direction perpendicular to the contact surface and penetrating the blade fixing seat 15 is in the same direction as the component of the gravity of the blade fixing seat 15 and the blade in the tangential direction of the movement, thereby exerting greater pressure on the blade fixing seat 15 and the blade, increasing the contact pressure between the blade head and the electrode plate 2, and improving the scraping efficiency and effect.

[0060] The blade fixing seat 15 is provided with a driving rod movable groove 151, which gives the blade fixing seat 15 a movable margin. Although in normal scraping work, the side wall of the driving rod movable groove 151 close to the blade fixing seat 15 will be in close contact with the driving rod 141. However, when a relatively hard and unremovable black copper powder block appears on the electrode plate 2, when the blade head scrapes there, the blade set 1 will not be stuck, but the blade fixing seat 15 equipped with the blade encountering the hard black copper powder will passively rotate counterclockwise and lift up, thereby skipping the black copper powder there, and when it reaches the black copper powder below which is easy to scrape off, the blade fixing seat 15 will hit the black copper powder with a certain speed under the pressure of the blade contact section 132, thereby making it easier to scrape off the black copper powder.

[0061] The length of the driving rod 141 installed inside the driving shaft 14 is relatively large, exceeding the radius of the driving shaft, and the portion of the driving rod 141 inside the driving shaft 14 passes through the center of the driving shaft 14. The driving rod 141 also extends a section outside the driving shaft 14. The length of the extension section is greater than the wall thickness of the tubular structure of the blade fixing seat 15, so that the driving rod 141 can fully support the wall of the blade fixing seat 15, while also increasing the contact area and reducing the stress at the contact portion between the driving rod 141 and the blade fixing seat 15.

[0062] In addition, the exposed length of the driving rod 141 is also limited to be less than the minimum distance between the outer surface of the driving shaft 14 and the outer surface of the pressing member tensioning shaft 17. This avoids the risk of collision and interference between the driving rod 141 and the pressing member tensioning shaft 17 when the driving shaft 14 rotates and the driving rod 141 passes through the space between the driving shaft 14 and the pressing member tensioning shaft 17. This ensures safety during the working process and reduces possible damage to the equipment caused by collision.

[0063] Because the driving shaft 14 installed on the frame 16 is relatively long and is prone to bending and deformation in the middle part, at least one middle section support seat 162 is arranged between the driving shaft 14 and the frame 16. One end of the middle section support seat 162 is fixed to the frame 16, and the other end is provided with two holes according to the arrangement relationship between the driving shaft 14 and the clamping member tensioning shaft 17, through which the driving shaft 14 and the clamping member tensioning shaft 17 can pass respectively.

[0064] The device fixes the blade set 1 on the blade set mounting strip 3, so that the blade set 1 is installed in the device. The blade set mounting strip 3 is a hollow square tube. The length of the blade set mounting strip 3 is greater than the length of the blade set 1, and the width of the blade set mounting strip 3 is greater than or equal to the width of the bottom of the blade set 1.

[0065] At the bottom of the blade set 1, a blade set latch 161 is also provided. The blade set latch 161 is in the shape of a rectangular parallelepiped. The blade set latch 161 is provided at the center of the bottom of the blade set 1. Correspondingly, the blade set mounting strip 3 installed in cooperation with the blade set 1 is also provided with a corresponding position for accommodating the blade set latch 161. The blade set latch 161 can also be provided with multiple sections at the bottom of the blade set 1. The more sections there are, the better the positioning effect and the movement restriction effect will be, but the requirements for processing accuracy will be higher. In order to enable the blade set 1 to have two installation methods, the blade set 1 can be installed in opposite directions. Therefore, the blade set latch 161 is installed at the center of the bottom of the blade set 1. As long as the corresponding blade set latch 161 can meet the requirements of symmetrical distribution, the blade set 1 can be installed in opposite directions. Therefore, installing the blade set latch 161 at the center of the bottom of the blade set 1 is only an example in this embodiment. There are many other ways with similar effects that do not require creative thinking, which will not be repeated here.

[0066] The frame length of the blade assembly 1 is designed to be slightly shorter than the length of its bottom, which helps to achieve more precise positioning and adjustment during installation, and also helps to improve the structural stability of the entire blade assembly.

[0067] The drive shaft 14 passes through both sides of the blade set 1 and passes through the blade set installation narrow plate 5 and the blade set installation long plate 6 respectively. The drive shaft 14 is fixed to the housing of the device. This helps to fix the blade set 1 more firmly on the device, and is also conducive to the device to uniformly drive all the drive shafts 14, so as to uniformly drive all the blades to perform scraping work at the same time.

[0068] Embodiment 2: The structure of the blade set 1 in this embodiment is the same as that in the first embodiment. The main difference between this embodiment and the first embodiment is that this embodiment specifically describes how the device uniformly controls all blades.

[0069] like Figures 1 to 14 As shown, the present invention discloses a device for scraping off plate surface attachments, comprising a blade set 1 and an electrode plate 2, wherein the blade set 1 is fixedly connected to one side of a blade set mounting long plate 6 at intervals, and a blade set driving component 61 is provided on the other side of the blade set mounting long plate 6, and the blade set 1 is transmission-connected to the blade set driving component 61. The blade set 1 in the device for scraping off plate surface attachments of the present invention can adjust the number of blade sets 1 installed and placed in the device according to the number of electrode plates 2 to be scraped off and the need to scrape off the black copper powder attached to the electrode plates 2.

[0070] The blade assembly 1 is composed of a frame 16 and blades, and the frame 16 is in a relatively flat rectangular shape. A scraper assembly consisting of a plurality of long blades 11 and short blades 12 alternating with each other can be placed within the capacity of the frame 16, and the bottom of the frame 16 is connected to a long plate. Two shafts are provided from top to bottom near the lower part of the frame 16. The upper shaft is the drive shaft 14, and the lower shaft is the clamping member tensioning shaft 17. The projections of the axes of the drive shaft 14 and the clamping member tensioning shaft 17 can be overlapped or staggered on the plane, which has little effect on the scraping effect of the blade assembly 1 on the electrode plate 2.

[0071] The frame 16 is designed with a semi-enclosed structure, which provides a stable support and provides a mounting position for the long blade 11 and the short blade 12. The long blade 11 and the short blade 12 are installed alternately in the frame 16 and fixed on the drive shaft 14. The drive shaft 14 uniformly controls the angle between the scraper assembly consisting of a plurality of alternating long blades 11 and short blades 12 and the electrode plate 2 during the scraping operation. The installation of the drive shaft 14 on the frame. The drive shaft 14 is relatively long, and the installation position passes through the frame 16, and two relatively long sections extend outward from the through position on both sides of the frame 16.

[0072] Below the driving shaft 14, a clamping member tensioning shaft 17 is arranged parallel to the driving shaft 14. The main function of the clamping member tensioning shaft 17 is to limit the movement of the support rod. The clamping member tensioning shaft 17 limits the elastic clamping member 13 installed on the driving shaft 14. By limiting the movement of the elastic clamping member 13, the deformation of the elastic clamping member 13 is increased, and the elastic force of the elastic clamping member 13 is increased. The downward pressure applied by the elastic clamping member 13 to the long blade 11 and the short blade 12 can make the long blade 11 and the short blade 12 more firmly pressed on the plate surface of the pole plate 2 when in contact with the pole plate 2, thereby improving the effect of scraping off the black copper powder on the pole plate 2. It is ensured that the long blade 11 and the short blade 12 will not easily jump during the scraping process, resulting in poor panel scraping effect of the pole plate 2.

[0073] Because the black copper powder is a metal product precipitated from an acidic solution, it is highly corrosive before cleaning, and the frame 16, the long blade 11, and the corresponding short blade 12 need to be in contact with the black copper powder for a long time during operation, and are easily corroded. In order to enhance the practicality and durability of the blade set 1. The frame 16 can be made of stainless steel, or electroplated on the surface of the frame 16 so that a corrosion-resistant layer is attached to the surface of the frame 16.

[0074] Although the frame 16 is less impacted than the long blade 11 and the short blade 12 when scraping the panel of the electrode plate 2, it will also have more contact and friction with the black copper powder, and the electroplating layer is easily corroded, resulting in protection failure. Therefore, compared with surface treatment of the frame 16, it is more preferable to select stainless steel material to manufacture the frame 16. Using stainless steel is not only lower in cost, but also conducive to mass production and simplified production process.

[0075] Because the long blade 11 and the short blade 12 are in direct contact with the pole plate 2 and produce friction, the working environment of the long blade 11 and the short blade 12 is more severe, and the material requirements of the blade are higher. On the one hand, the blade needs to scrape off the black copper powder attached to the panel of the pole plate 2, which requires the long blade 11 and the short blade 12 to have a higher hardness. On the other hand, the long blade 11 and the short blade 12 need to be in contact with the highly corrosive black copper powder for a long time, and the corrosion resistance of the long blade 11 and the short blade 12 is also required to be higher. Stainless steel with good hardness and corrosion resistance can be selected for production.

[0076] In the blade set 1, the long blade 11 and the short blade 12 are different in length and structure at the blade head, but have the same blade width. In order to drive the movement of the flat long blade 11 and the short blade 12, a blade fixing seat 15 is fixedly installed on the long blade 11 and the short blade 12 and then fixed on the driving shaft 14. The connection part between the blade fixing seat 15 and the long blade 11 and the short blade 12 uses a flat plate structure, which can make the connection between the blade fixing seat 15 and the long blade 11 and the short blade 12 more firm and reliable during the installation process. Two long blade mounting holes 112 are provided at the lower part of the long blade 11 and two short blade mounting holes 122 are provided at the lower part of the short blade 12, which are matched with the blade mounting holes on the blade fixing seat 15.

[0077] The blade fixing seat 15 is connected to the drive shaft 14 through a tubular structure provided on the blade fixing seat 15. Compared with the conventional integrated shaft-tube connection method, in the present invention, a piece of the blade fixing seat 15 and the drive shaft 14 is connected to the tubular structure of the blade fixing seat 15 and is cut off from the middle of the tubular structure, only completely cutting off the tubular structure, and not completely cutting off the flat plate structure connecting the blade fixing seat 15 and the blade. At the position where the tubular structure is cut off, the width of the cut-off gap can accommodate the installation of the elastic pressure piece 13. And the elastic pressure piece 13 is not given too much movement margin on the axis of the drive shaft 14, reducing the sliding of the elastic pressure piece 13 on the drive shaft 14, reducing the noise and wear of the equipment operation.

[0078] When the blade fixing seat 15 and the elastic pressing member 13 are installed on the driving shaft 14, the elastic pressing member 13 needs to be placed in the gap at the cut-off portion of the blade fixing seat 15 before the blade fixing seat 15 and the elastic pressing member 13 are sequentially sleeved on the driving shaft 14. Accordingly, when the blade fixing seat 15 and the elastic pressing member 13 are installed on the driving shaft 14, the long blade 11 or the short blade 12 can be selectively installed on the blade fixing seat 15.

[0079] The elastic pressing member 13 is a coil-shaped structure, which is a torsion spring structure. The tubular structure in the middle of the elastic pressing member 13 cooperates with the driving shaft 14 and is sleeved on the driving shaft 14. When the driving shaft 14 rotates, the blade fixing seat 15 can be driven to rotate synchronously, but the elastic pressing member 13 will not rotate with the driving shaft 14.

[0080] Because the two ends of the elastic pressing member 13 extend outwardly to form a blade contact section 132 and a tension section 131. The blade contact section 132 is in close contact with the surface of the blade, and the position where the blade contact section 132 contacts the long blade 11 or the short blade 12 is on the back side relative to the contact surface of the long blade 11 and the short blade 12 with the blade fixing seat 15, so that downward pressure can be applied to the blade. The contact position of the blade contact section 132 with the blade is located near the lower part of the blade and at the center of the blade surface.

[0081] The long blade 11 is relatively long, and has a convex blade side convex section 111 extending to both sides at the blade head position, and two long blade mounting holes 112 are provided at the bottom of the blade body of the long blade 11. The short blade 12 is shorter than the long blade 11, and has no convexity extending to both sides at the blade head position, and two short blade mounting holes 122 are provided at the bottom of the blade body of the short blade 12. Therefore, in order to avoid interference between the long blade 11 and the long blade 11, the blade set 1 combines the long blade 11 and the short blade 12 in a cross-spaced combination.

[0082] On the one hand, the blade contact section 132 of the elastic pressing member 13 can further ensure the tight connection between the blade and the blade fixing seat 15. On the other hand, as the blade is lifted, the blade contact section 132 will be continuously lifted, while the main structure of the elastic pressing member 13 will not rotate, so that the deformation angle of the elastic pressing member 13 is continuously increased, further increasing the pressure applied by the blade contact section 132 to the blade, and increasing the pressure of the blade on the electrode plate 2 during the scraping work of the electrode plate 2, so that the blade and the surface of the electrode plate 2 are in contact more firmly and more closely, and the scraping effect of the black copper powder on the electrode plate 2 is better.

[0083] A clamping member tensioning shaft 17 is provided below the driving shaft 14, and the clamping member tensioning shaft 17 is a fixed limiting shaft of the elastic clamping member 13. The clamping member tensioning shaft 17 limits the elastic clamping member 13 from following the movement of the driving shaft 14 and rotating. Another extension section of the elastic clamping member 13 is a tensioning section 131, and the tensioning section 131 cooperates with the clamping member tensioning shaft 17 to limit the rotation of the elastic clamping member 13.

[0084] The clamping member tensioning shaft 17 is fixedly mounted on the frame 16 and is not driven to rotate, but can be fixedly mounted or rotatably mounted on the frame 16. The tensioning section 131 is hook-shaped or spoon-shaped. The length of the tensioning section 131 is greater than the diameter of the clamping member tensioning shaft 17, and the end of the tensioning section 131 is located below the clamping member tensioning shaft 17. The tensioning section 13 can cover most of the cross-section of the clamping member tensioning shaft 17. There is a turning point below the tensioning section 13, and the turning angle is greater than or equal to ninety degrees, which is a right angle or an obtuse angle.

[0085] The turning point at the lower end of the tensioning section 131 can better hook the tensioning shaft 17 of the pressing member, and can ensure that during the rotation of the driving shaft 14, the tensioning section 131 can firmly hook the tensioning shaft 17 of the pressing member, so that the deformation of the elastic pressing member 13 increases continuously with the rotation of the driving shaft 14, thereby increasing the pressure that can be applied by the elastic pressing member 13, and ensuring the scraping effect.

[0086] Because each of the long blades 11 and the short blades 12 is independently connected to a blade fixing seat 15, the rotation of the long blades 11 and the short blades 12 needs to follow the blade fixing seat 15 installed with the long blades 11 and the short blades 12. In order to drive the blade fixing seat 15 to rotate with the driving shaft 14. Therefore, at the location of the tubular structure of each blade fixing seat 15 and the shaft section of the driving shaft 14 that matches, a driving rod 141 is provided on the driving shaft 14. The driving rod 141 is in the shape of a threaded rod, is installed on the driving shaft 14, and has a shaft section extending outward.

[0087] Correspondingly, at the position on the blade fixing seat 15 that matches the driving rod 141, a driving rod movable groove 151 is provided on the blade fixing seat 15. The driving rod movable groove 151 is an opening opened on the tubular structure of the blade fixing seat 15. On one blade fixing seat 15, at least one of the two tubular structures is provided with one driving rod movable groove 151. The arc range of the driving shaft movable groove is preferably between 1 / 8π and 1 / 4π, and can be slightly larger than 1 / 4π.

[0088] When the drive shaft 14 needs to push the blade fixing seat 15 to lift up, the drive rod 141 will press against the side of the drive rod movable slot 151 that is closer to the blade, and the drive shaft 14 drives the drive rod 141 to rotate counterclockwise, thereby pushing the blade fixing seat 15 to rotate counterclockwise and be lifted up. To put down the blade fixing seat 15, it is only necessary to drive the drive shaft 14 clockwise. When the drive rod 141 no longer presses against the blade fixing seat 15, the blade fixing seat 15 and the blade are naturally put down under the action of gravity and pressing force, and contact the drive rod 141.

[0089] When the blade fixing seat 15 rotates to an excessively large angle and the center line of the blade fixing seat 15 passes over the other side of the vertical plane, although the blade fixing seat 15 has a tendency to maintain counterclockwise rotation due to gravity, the elastic pressing member 13 has a large deformation at this time, and a force perpendicular to the contact surface and penetrating the blade fixing seat 15 is always applied to the blade and the blade fixing seat 15, and the magnitude of the force is large enough to overcome a large part of the component of the gravity of the blade fixing seat 15 and the blade in the tangential direction of the movement, thereby preventing or even overcoming the tendency of the blade fixing seat 15 to continue to rotate counterclockwise.

[0090] In normal operation, the force that the elastic pressing member 13 always applies to the blade in a direction perpendicular to the contact surface and penetrating the blade fixing seat 15 is in the same direction as the component of the gravity of the blade fixing seat 15 and the blade in the tangential direction of the movement, thereby exerting greater pressure on the blade fixing seat 15 and the blade, increasing the contact pressure between the blade head and the electrode plate 2, and improving the scraping efficiency and effect.

[0091] The blade fixing seat 15 is provided with a driving rod movable groove 151, which leaves a margin for movement for the blade fixing seat 15. Although in normal scraping work, the wall of the driving rod movable groove 151 close to the blade fixing seat 15 will be in close contact with the driving rod 141. However, when a relatively hard and unremovable black copper powder block appears on the electrode plate 2, when the blade head scrapes there, the blade set 1 will not be stuck, but the blade fixing seat 15 equipped with the blade that encounters the hard black copper powder will passively rotate counterclockwise and lift up, thereby skipping the black copper powder there. When it reaches the black copper powder that is easy to scrape off below, the blade fixing seat 15 will hit the black copper powder at a certain speed under the pressure of the blade contact section 132, thereby making it easier to scrape off the black copper powder.

[0092] The length of the driving rod 141 installed inside the driving shaft 14 is relatively large, exceeding the radius of the driving shaft, and the portion of the driving rod 141 inside the driving shaft 14 passes through the center of the driving shaft 14. The driving rod 141 also extends a section outside the driving shaft 14. The length of the extension section is greater than the wall thickness of the tubular structure of the blade fixing seat 15, so that the driving rod 141 can fully support the wall of the blade fixing seat 15, while also increasing the contact area and reducing the stress at the contact portion between the driving rod 141 and the blade fixing seat 15.

[0093] In addition, the exposed length of the driving rod 141 is also limited to be less than the minimum distance between the outer surface of the driving shaft 14 and the outer surface of the pressing member tensioning shaft 17. This avoids the risk of collision and interference between the driving rod 141 and the pressing member tensioning shaft 17 when the driving shaft 14 rotates and the driving rod 141 passes through the space between the driving shaft 14 and the pressing member tensioning shaft 17. This ensures safety during the working process and reduces possible damage to the equipment caused by collision.

[0094] Because the driving shaft 14 installed on the frame 16 is relatively long and is prone to bending and deformation in the middle part, at least one middle section support seat 162 is arranged between the driving shaft 14 and the frame 16. One end of the middle section support seat 162 is fixed to the frame 16, and the other end is provided with two holes according to the arrangement relationship between the driving shaft 14 and the clamping member tensioning shaft 17, through which the driving shaft 14 and the clamping member tensioning shaft 17 can pass respectively.

[0095] The device fixes the blade set 1 on the blade set mounting strip 3, so that the blade set 1 is installed in the device. The blade set mounting strip 3 is a hollow square tube. The length of the blade set mounting strip 3 is greater than the length of the blade set 1, and the width of the blade set mounting strip 3 is greater than or equal to the width of the bottom of the blade set 1.

[0096] At the bottom of the blade set 1, a blade set latch 161 is also provided. The blade set latch 161 is in the shape of a rectangular parallelepiped. The blade set latch 161 is provided at the center of the bottom of the blade set 1. Correspondingly, the blade set mounting strip 3 installed in cooperation with the blade set 1 is also provided with a corresponding position for accommodating the blade set latch 161. The blade set latch 161 can also be provided with multiple sections at the bottom of the blade set 1. The more sections there are, the better the positioning effect and the movement restriction effect will be, but the requirements for processing accuracy will be higher. In order to enable the blade set 1 to have two installation methods, the blade set 1 can be installed in opposite directions. Therefore, the blade set latch 161 is installed at the center of the bottom of the blade set 1. As long as the corresponding blade set latch 161 can meet the requirements of symmetrical distribution, the blade set 1 can be installed in opposite directions. Therefore, installing the blade set latch 161 at the center of the bottom of the blade set 1 is only an example in this embodiment. There are many other ways with similar effects that do not require creative thinking, which will not be repeated here.

[0097] The frame length of the blade assembly 1 is designed to be slightly shorter than the length of its bottom, which helps to achieve more precise positioning and adjustment during installation, and also helps to improve the structural stability of the entire blade assembly.

[0098] The drive shaft 14 passes through both sides of the blade set 1 and passes through the blade set installation narrow plate 5 and the blade set installation long plate 6 respectively. The drive shaft 14 is fixed to the housing of the device. This helps to fix the blade set 1 more firmly on the device, and is also conducive to the device to uniformly drive all the drive shafts 14, so as to uniformly drive all the blades to perform scraping work at the same time.

[0099] One end of one of the blade sets 1 is mounted on one of the blade set mounting narrow plates 5, specifically, one end of the blade set mounting strip 3 on which the blade set 1 is mounted is mounted on the blade set mounting narrow plate 5. A plate fixing strip 4 is mounted between two blade set mounting narrow plates 5, the upper end of which is flush with the upper end of the blade set mounting narrow plates 5, the plate 2 is placed on the plate fixing strip 4, and the plate fixing strip 4 also has the function of connecting two independent blade set mounting narrow plates 5.

[0100] Because one end of the electrode plate 2 is to be placed on the blade assembly mounting narrow plate 5, and the other end is to be mounted on the blade assembly mounting long plate 6. And the plate surface of the electrode plate 2 is to be parallel to the scraping surface of the blade assembly. Therefore, an electrode plate fixing strip 4 is mounted on the blade assembly mounting long plate 6 in a one-to-one correspondence with the blade assembly mounting narrow plate 5. The connecting line of the two electrode plate fixing strips 4 on the blade assembly mounting long plate 6 in a one-to-one correspondence with the blade assembly mounting narrow plate 5 is parallel to the working surface of the blade assembly 1.

[0101] One end of the pole plate 2 is placed on the pole plate fixing strip 4 of the blade assembly mounting narrow plate 5, and the other end is placed on the pole plate fixing strip 4 on the blade assembly mounting long plate 6.

[0102] The openings between adjacent blade groups 1 face opposite directions, so that both sides of a plate 2 can be scraped by two blade groups 1 at the same time, and the black copper powder on a plate 2 can be scraped off at one time. At least two blade group drive components 61 are provided on the blade group mounting long plate 6, and one end of the blade group drive component 61 is provided with a fixed portion 613, and the fixed portion 613 is rotatably connected to a telescopic mechanism 612, and the telescopic mechanism 612 is rotatably connected to a synchronous drive connection block 615, and the synchronous drive connection block 615 is connected to the synchronous drive rod 62. The connection position of the telescopic mechanism 612 and the fixed portion is a first hinge point 614, and the connection position of the telescopic mechanism and the synchronous drive connection block 615 is a second hinge point 616.

[0103] The two parts connected by the first hinge point 614 can rotate relative to each other, and the two parts connected by the second hinge point 615 can also rotate relative to each other. The telescopic mechanism 612 can extend and push the synchronous drive connection block 615 to move, and during the movement, the drive connection block 615 is fixedly connected to the synchronous drive rod 62. When the telescopic mechanism 612 is extended and retracted, the synchronous drive rod 62 remains horizontal while the whole body moves in a circular motion.

[0104] One of the synchronous drive rods 62 is in transmission connection with the drive shaft 14 on the half of the blade assembly 1 with the same opening direction, and a drive shaft connecting rod 611 is provided between the synchronous drive rod 62 and the drive shaft 14. Therefore, one device will be provided with two synchronous drive rods 62, and the two synchronous drive rods 62 are arranged in parallel with a height difference between the two. Although there is a height difference between the two synchronous drive rods 62, the drive shaft connecting rod 611 connected to the synchronous drive rod 62 is located on the same straight line as the line connecting the centers of the connection positions of all the drive shafts 14 connected to it, and the straight line is also parallel to the synchronous drive rod 62. The drive shaft connecting rod 611 is fixedly connected to the drive shaft 14, and the drive shaft 14 rotates the same arc in the same direction as the drive shaft connecting rod 611 rotates.

[0105] The centers of the driving shafts 14 on the same device are located on the same straight line at the installation positions of the blade assembly installation long plates 6, and the electrode plates 2 being processed are placed between the two adjacent blade assemblies 1 with openings facing each other, and the electrode plates 2 to be processed are placed between the two adjacent blade assemblies 1 with openings facing away from each other. The device can store the electrode plates 2 being processed and can also store the electrode plates 2 that have not yet been processed but can be processed after the previous electrode plate 2 is processed.

[0106] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
