Description

Technical Field

[0001] This utility model relates to the field of gravure roller electroplating technology, and in particular to an electroplating device for forming a metal coating on the surface of a gravure roller. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhancing aesthetics.

[0003] In gravure printing, the surface of the gravure roller needs to be chrome-plated using a chrome plating device. Chrome plating can improve the surface hardness, protect the gravure roller, and improve its printing durability. At the same time, the chrome plating layer has strong hardness, wear resistance, and chemical stability, which allows the surface of the gravure roller to maintain its gloss for a long time after chrome plating.

[0004] When electroplating a gravure roller, the anode plate needs to be arranged at intervals with the gravure roller. Under the action of the electroplating solution, charged ions are ionized to the surface of the gravure roller to form a metal coating. Since gravure rollers of different sizes require different spacing from the anode plate, the spacing is usually adjusted by adjusting the spacing on both sides. Since the anode plate also needs to be set below the gravure roller, at least three anode plates need to be set up, arranged at intervals with the gravure roller. To achieve equidistant spacing between the anode plates on all three sides and the gravure roller, an additional mechanism is needed to adjust the spacing on the third side, which is costly and difficult to achieve synchronous adjustment. Utility Model Content

[0005] The purpose of this invention is to provide an electroplating device for forming a metal coating on the surface of a gravure roller, addressing the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An electroplating device for forming a metal coating on the surface of a gravure roller includes an electroplating tank for positioning the gravure roller, and side mounting plates are respectively installed on the front and rear sides of the electroplating tank. The device is characterized in that: a pair of parallel and spaced anode modules are arranged inside the electroplating tank; each anode module includes an anode plate, and a bottom plate extending laterally inward is formed at the bottom of the anode plate. The bottom plate has multiple alternately arranged guide grooves and guide blocks along its length; the guide groove of the bottom plate on the left side is laterally aligned with the guide block of the bottom plate on the right side.

[0008] The electroplating tank is also equipped with an adjustment mechanism for adjusting the distance between the two anode plates. The adjustment mechanism includes a lifting seat that can move longitudinally and a pair of symmetrically arranged sliding modules. The two side mounting plates are coaxially formed with electroplating holes for the intaglio roller to enter and exit. The two sliding modules are symmetrically arranged on the left and right sides of the electroplating holes. The sliding module includes an adjusting sliding seat that slides longitudinally along the side mounting plate. The adjusting sliding seat is connected to the anode plate. The lifting seat is equipped with a pair of symmetrically arranged connecting arms that can swing longitudinally. The connecting arms are rotatably connected to the adjusting sliding seat.

[0009] The beneficial effects of this utility model are as follows: the gravure roller is placed between two side mounting plates, and then the distance between the two anode plates is adjusted by the adjustment mechanism; by moving the lifting seat, the lifting seat can drive the adjusting sliding seat to move up and down along the side mounting plates at an angle through the connecting arm, so that the included angle of the two connecting arms changes. Since the adjusting sliding seat is connected to the anode plates, the two anode plates will move closer or further away from each other, thereby realizing the adjustment of the distance between the two anode plates, which is convenient for matching gravure rollers of different sizes, and the electroplating quality is better during electroplating.

[0010] Because the two anode plates move at an angle when adjusting their spacing, their heights change synchronously, meaning the height of the bottom plate formed at the bottom of the anode plates changes synchronously. When the two anode plates move closer or further apart, the bottom plates slide into each other through guide grooves and guide blocks, ensuring that the bottom surface of the gravure roller can also be electroplated. This makes the distances between the left and right sides and the bottom of the gravure roller and the anode plates the same, ensuring that the ion ionization paths are basically the same. This optimizes the thickness of the metal coating after electroplating, and the metal coating thickness on the surface of the gravure roller is basically the same, effectively improving the quality of electroplating.

[0011] Furthermore, because the guide groove on the left bottom plate is laterally aligned with the guide block on the right bottom plate, the two bottom plates remain flush and form a single planar structure when adjusting the spacing between the two anode plates. The bottom plates and anode plates are an integral structure with rounded corners at the joints, allowing them to perform the same electroplating function as the sides. The cooperation between the guide groove and guide block prevents the two anode plates from colliding, and the bottom electroplating area maintains a planar structure during adjustment. No additional mechanisms are needed for adjusting the spacing in the bottom area, saving costs. Attached Figure Description

[0041] The present invention will now be described in detail with reference to the accompanying drawings.

[0042] like Figure 1-10 As shown, an electroplating device for forming a metal coating on the surface of a gravure roller includes an electroplating tank 1 for positioning the gravure roller, and side mounting plates 11 installed on the front and rear sides of the electroplating tank 1. A pair of parallel, spaced-apart anode plates 30 are arranged inside the electroplating tank 1. A bottom plate 4 extending laterally inward is formed at the bottom of each anode plate 30. Multiple alternately arranged guide grooves 41 and guide blocks 42 are formed along the length of the bottom plate 4; the guide grooves 41 of the left bottom plate 4 are laterally aligned with the guide blocks 42 of the right bottom plate 4.

[0043] The electroplating tank 1 is provided with a pair of spaced anode modules 3, each anode module 3 including an anode plate 30. The electroplating tank 1 is also provided with an adjustment mechanism 2 for adjusting the distance between the two anode plates 30. The adjustment mechanism 2 includes a lifting seat 21 that can move longitudinally and a pair of symmetrically arranged sliding modules 20. The sliding module 20 includes an adjustment sliding seat 26 that slides longitudinally along the side mounting plate 11. The adjustment sliding seat 26 is connected to the anode plate 30. The lifting seat 21 is equipped with a pair of symmetrically arranged connecting arms 23 that can swing longitudinally. The connecting arms 23 are rotatably connected to the adjustment sliding seat 26.

[0044] The gravure roller is placed between two side mounting plates 11, and then the distance between the two anode plates 30 is adjusted by the adjusting mechanism 2. By moving the lifting seat 21, the lifting seat 21 can drive the adjusting sliding seat 26 to move up and down along the side mounting plate 11 via the connecting arm 23, so that the included angle of the two connecting arms 23 changes. Since the adjusting sliding seat 26 is connected to the anode plate 30, the two anode plates 30 will move closer or further away from each other, thereby realizing the adjustment of the distance between the two anode plates 30, which is convenient for matching gravure rollers of different sizes, and the electroplating quality is better during electroplating.

[0045] Since the two anode plates 30 move at an angle when adjusting their spacing, their heights change synchronously, meaning the height of the bottom plate 4 formed at the bottom of the anode plates 30 changes synchronously. When the two anode plates 30 move closer or further apart, the bottom plates 4 slide into each other through the guide groove 41 and guide block 42, ensuring that the bottom surface of the gravure roller can also be electroplated. This makes the distances between the left and right sides and the bottom of the gravure roller and the anode plates the same, ensuring that the ion ionization paths are basically the same. This optimizes the thickness of the metal coating after electroplating, and the thickness of the metal coating on the surface of the gravure roller is basically the same, effectively improving the quality of electroplating.

[0046] Furthermore, since the guide groove 41 of the left bottom plate 4 is laterally aligned with the guide block 42 of the right bottom plate 4, the two bottom plates 4 can remain flush and form a flat plate structure when adjusting the spacing of the two anode plates 30. The bottom plate 4 and the anode plate 30 are an integral structure with rounded corners at the connection, allowing them to have the same electroplating function as the side. The cooperation between the guide groove 41 and the guide block 42 prevents the two anode plates 30 from colliding, and the bottom electroplating area maintains a flat structure during adjustment. No additional mechanisms are needed for adjusting the spacing of the bottom area, saving costs.

[0047] The anode plate 30 is disposed between two side mounting plates 11, and the anode plate 30 is arranged perpendicularly to the side mounting plates 11. The side mounting plates 11 are formed with electroplating holes 17 for the gravure roller to enter. The anode plates 30 are symmetrically arranged on both sides of the electroplating holes 17. Since the two anode plates 30 are placed on both sides of the gravure roller, when the spacing is adjusted, the two anode plates 30 will move closer or further away from each other at the same time. The distance between the two anode plates 30 and the gravure roller is the same, which ensures that when the ions are free on both sides of the electroplating tank 1, the path is basically the same, and the coating after electroplating on the surface of the gravure roller is more uniform and of better quality.

[0048] The sliding module 20 also includes guide rails 24 inclinedly arranged on the side mounting plate 11, with two guide rails 24 symmetrically arranged around the electroplating holes 17. Guide sliding seats 25 are slidably mounted on the guide rails 24, and adjusting sliding seats 26 are mounted on top of the guide sliding seats 25. Limiting seats 27 are installed at the top and bottom of the guide rails 24 respectively. When the lifting seat 21 moves up and down, the adjusting sliding seat 26 cooperates with the guide sliding seat 25 to move along the length of the guide rails 24, thereby causing the two anode plates 30 to move closer or further apart. The limiting seats 27 prevent the guide sliding seat 25 from falling off the guide rails 24 during movement, ensuring the stability of the movement.

[0049] Furthermore, since the two guide rails 24 are symmetrically arranged on both sides of the electroplating hole 17, when the adjusting sliding seat 26 moves along the length of the guide rail 24 in conjunction with the guide sliding seat 25, the anode plate 30 can move up and down, and the spacing can be adjusted; when the side distance between the anode plate 30 and the gravure roller is adjusted, the distance between the bottom plate 4 and the gravure roller is adjusted synchronously, thereby realizing the synchronous adjustment of the distance between the three sides and the gravure roller.

[0050] Furthermore, a support base 28 is mounted on the top of the adjusting sliding seat 26. The top of the support base 28 is formed with a recessed fitting groove 29. A conductive plate 31 is connected to the top of the anode plate 30, and the outer end of the conductive plate 31 is connected to the fitting groove 29. The top of the anode plate 30 extends towards the side mounting plate 11 through the conductive plate 31 and connects with the fitting groove 29 of the support base 28, thereby enabling movement to adjust the distance between the two anode plates 30.

[0051] Preferably, the side mounting plate 11 is also formed with a guide groove 32 for guiding the conductive plate 31 to move, and the guide groove 32 is arranged parallel to the guide rail 24. An inner sliding seat 33 and an inner sliding module for guiding the inner sliding seat 33 to slide are installed at the inner end of the guide groove 32; when the sliding seat 26 is adjusted to slide tilted along the guide rail 24, the inner sliding module simultaneously slides tilted along the length direction of the guide groove 32, thereby driving the anode plate 30 to move.

[0052] Furthermore, the inner sliding seat 33 is formed with a through mounting groove 34 for the conductive plate 31 to pass through. The inner sliding module includes a top guide rail 35 mounted on the top of the guide groove 32 and a bottom guide rail 36 mounted on the bottom of the guide groove 32. The top guide rail 35 and the bottom guide rail 36 are arranged in parallel and spaced apart. The top guide rail 35 and the bottom guide rail 36 form a sliding space for the inner sliding seat 33 to slide in a limited manner. Since the lengths of the top guide rail 35 and the bottom guide rail 36 are limited, it can prevent the inner sliding seat 33 from exceeding its stroke when moving, thus forming a limited sliding.

[0053] Furthermore, the adjustment mechanism 2 also includes a lifting drive mechanism 11 that drives the lifting seat 21 to move up and down. The lifting drive mechanism 11 includes a drive sprocket 16 mounted on the side mounting plate 11, and a transmission chain 15 is sleeved on the drive sprocket 16. The bottom end of the transmission chain 15 is connected to the lifting seat 21. A rotatable transmission shaft 12 passes between the side mounting plates 11. A drive sprocket 14 is sleeved at both ends of the transmission shaft 12. The drive sprocket 14 and the drive sprocket 16 are connected by the transmission chain 15.

[0054] In this embodiment, the drive shaft 12 rotates, and the drive sprockets 14 mounted on the side mounting plate 11 rotate. The drive sprockets 14, in conjunction with the drive chain 15, drive the drive sprocket 16 to rotate. When the drive sprocket 16 rotates, the drive chain 15 moves, and the lifting seat 21 connected to the bottom end of the drive chain 15 can move up and down. This causes the included angle of the two connecting arms 23 to change. Since the adjusting sliding seat 26 is connected to the anode plate 30, the two anode plates 30 will move closer or further away from each other, thereby realizing the adjustment of the distance between the two anode plates 30.

[0055] One of the side mounting plates 11 is equipped with a drive motor 13, which is connected to the transmission shaft 12 and can drive the transmission shaft 12 to rotate. The lifting seats 21 of the two side mounting plates 11 can move simultaneously, and in conjunction with the sliding module 20, the two anode plates 30 can move synchronously and the spacing can be adjusted.

[0056] Preferably, the lifting seat 21 has hinge grooves 22 formed at both ends, the top of the connecting arm 23 is hinged to the hinge groove 22, and the bottom of the connecting arm 23 is rotatably connected to the adjusting sliding seat 26. The hinge grooves 22 formed at both ends of the lifting seat 21 allow the connecting arm 23 to swing longitudinally; when the lifting seat 21 descends, the included angle between the two connecting arms 23 is larger, that is, the distance between the two sliding modules 20 is greater, and the distance between the two anode plates 30 increases; conversely, when the lifting seat 21 rises, the included angle between the two connecting arms 23 is smaller, that is, the distance between the two sliding modules 20 is closer, and the distance between the two anode plates 30 decreases; this is used to match gravure rollers of different sizes, and the practicality is further improved during electroplating.

[0057] The anode plate 30 is equipped with shielding plates 46 formed by insulating material at both ends; the anode plate 30 is provided with a moving mechanism 5 that drives the shielding plates 46 to move along the length of the conductive plate 31. The moving mechanism 5 includes a first moving seat 51 and a second moving seat 52. The first moving seat 51 and the second moving seat 52 move relative to each other along the conductive plate 31. The first moving seat 51 is connected to one of the shielding plates 46, and the second moving seat 52 is connected to the other shielding plate 46.

[0058] The gravure roller to be electroplated is placed parallel to the side of the anode plate 30. The shielding plate 46 can be adjusted laterally according to the length of the gravure roller. When adjusting the position, the first moving seat 51 and the second moving seat 52 move relative to each other, so that the two shielding plates 46 move closer or further away from each other at the same time. The shielding plate 46 can be moved to align with the end position of the gravure roller. The shielding plate 46 separates the anode plate 30 from the end of the gravure roller, protects the end of the gravure roller, and prevents ions from accumulating in the end area of ​​the gravure roller when they are free in the electroplating tank 1. This ensures the uniformity of ions during ionization, guarantees the electroplating quality, and improves the electroplating stability of the gravure roller.

[0059] The moving mechanism 5 also includes a transmission rope 53 arranged along the length of the conductive plate 31. One long side of the transmission rope 53 is connected to the first moving seat 51, and the other long side of the transmission rope 53 is connected to the second moving seat 52. The moving mechanism 5 also includes a drive wheel 54 rotatably mounted at one end of the conductive plate 31, and a driven wheel 55 rotatably mounted at the other end of the conductive plate 31. The transmission rope 53 is sleeved between the drive wheel 54 and the driven wheel 55. In this embodiment, with the cooperation of the drive wheel 54 and the driven wheel 55 and the transmission rope 53, the transmission rope 53 is arranged on the conductive plate 31 in a ring-shaped track structure to achieve movement. During movement, the two long sides of the transmission rope 53 move in opposite directions. Since one long side of the transmission rope 53 is connected to the first moving seat 51 and the other long side of the transmission rope 53 is connected to the second moving seat 52, the first moving seat 51 and the second moving seat 52 will move closer or further away from each other simultaneously, which can drive the two shielding plates 46 to move closer or further away from each other.

[0060] The above structure ensures that the two shielding plates 46 move closer or further apart synchronously, and the lateral position can be quickly and accurately adjusted according to the length of the gravure roller to protect the end of the gravure roller.

[0061] Furthermore, the conductive plate 31 has multiple stabilizing seats 56 arranged along its length, with adjacent stabilizing seats 56 laterally aligned. Each stabilizing seat 56 has a transmission hole 57 for the transmission rope 53 to pass through. The multiple stabilizing seats 56 can guide the transmission rope 53, preventing it from sagging and keeping it basically level. When the transmission rope 53 moves, it can stably drive the first moving seat 51 and the second moving seat 52 to move closer or further apart simultaneously.

[0062] Furthermore, drive plates 6 are respectively installed at both ends of the conductive plate 31. One drive plate 6 is equipped with the driving wheel 54 and a drive motor 58 that is pulsatorically connected to the driving wheel 54. The other drive plate 6 is equipped with the driven wheel 55. The drive motor 58 is pulsatorically connected to the driving wheel 54 and can drive the driving wheel 54 to rotate. Under the transmission of the transmission rope 53, the driven wheel 55 rotates synchronously to drive the transmission rope 53 to move, thereby realizing the lateral position adjustment of the shielding plate 46.

[0063] The drive plate 6 has an adjusting groove 61 formed along its length. A fixing plate 62 is installed on the outer end of the conductive plate 31. The fixing plate 62 is connected to the drive plate 6 and a first tensioning screw 63 is installed on the fixing plate 62. The first tensioning screw 63 passes through the adjusting groove 61 and is connected to the drive plate 6. Since the drive plate 6 is installed on the fixing plate 62 through the first tensioning screw 63, when the nut on the first tensioning screw 63 is loosened, the drive plate 6 can move laterally, so that the position of the drive plate 6 can be moved laterally to adjust the lateral position of the driving wheel 54 or the driven wheel 55, thereby adjusting the tension of the transmission rope 53 and preventing the transmission rope 53 from being too tight or too loose.

[0064] Furthermore, guide wheels 64 are installed at both ends of the conductive plate 31, with two guide wheels 64 at each end. The gap between the two guide wheels 64 is smaller than the outer diameter of the drive wheel 54. Under the drive of the guide wheels 64, the distance between the two long sides of the transmission rope 53 is shortened, the dimensions of the two shielding plates 46 can be set to be the same, the distance between the first moving seat 51 and the second moving seat 52 is shortened, and the stability of the two shielding plates 46 is further improved when they move.

[0065] A connection structure is provided between the anode plate 30 and the conductive plate 31. The connection structure includes multiple parallel and spaced connecting plates 47. The top of the connecting plates 47 is mounted on the conductive plate 31, and the bottom of the connecting plates 47 is connected to the anode plate 30. The connection structure also includes a transverse fixing plate 43 that connects two adjacent connecting plates 47. The anode plate 30 is connected to the conductive plate 31 through the multiple connecting plates 47, thereby realizing the connection between the conductive plate 31 and the anode plate 30.

[0066] Furthermore, a transverse sliding seat 44 is installed on the back of the shielding plate 46. The transverse sliding seat 44 is formed with a back sliding groove 45 that slides and engages with the transverse fixed plate 43. The shielding plate 46 moves along the length of the conductive plate 31 via the transverse sliding seat 44. When the shielding plate 46 moves, it slides and engages with the transverse fixed plate 43 via the back transverse sliding seat 44, making the transverse movement of the shielding plate 46 more stable. The shielding plate 46 can maintain the protection of the anode plate 30 and the gravure roller, effectively avoiding the problem of a thicker electroplating layer on one side of the gravure roller.

[0067] A conductive connection structure 7 is provided between the two conductive plates 31. The conductive connection structure 7 is respectively provided at both ends of the conductive plates 31. The conductive connection structure 7 includes a conductive connection plate 78 provided on the outside of the side mounting plate 11. The conductive connection plate 78 is arranged longitudinally and is located between the two conductive plates 31. Flexible conductive strips 74 are respectively connected to both sides of the conductive connection plate 78. The other end of the flexible conductive strips 74 is connected to the conductive plate 31.

[0068] A first conductive drive plate 71 is provided between the two side mounting plates 11. A second conductive transition plate 72 is installed at both ends of the first conductive drive plate 71. An insulating support base 73 made of insulating material is provided on the side mounting plate 11. The second conductive transition plate 72 is installed on the insulating support base 73 and is conductively connected to the conductive connecting plate 78.

[0069] Specifically, the bottom of the conductive connecting plate 78 is provided with a conductive connecting hole 75, and one end of the flexible conductive strip 74 is equipped with a first conductive fixing seat 76 made of hard metal. The two first conductive fixing seats 76 are respectively attached to both sides of the conductive connecting plate 78 and are fixedly connected to the conductive connecting plate 78. The other end of the flexible conductive strip 74 is equipped with a second conductive fixing seat 77 made of hard metal, and the second conductive fixing seat 77 is fixedly connected to the conductive plate 31.

[0070] Through the conductive connection structure 7, with the cooperation of the first conductive drive plate 71 and the second conductive transition plate 72, both ends of the conductive plate 31 can be energized. With the help of the flexible conductive strip 74, the two conductive plates 31 conduct electricity simultaneously and always remain conductive without any power outage. This allows the current to be transmitted simultaneously from both ends of the conductive plate 31 to both ends of the two conductive plates 31, achieving stable conductivity.

[0071] Since the conductive connecting plate 78 and the conductive plate 31 are electrically connected by a flexible conductive strip 74, when the distance between the two anode plates 30 is adjusted, one end of the flexible conductive strip 74 is always fixedly connected to the conductive connecting plate 78 through the first conductive fixing seat 76 to maintain the conductive connection; the other end is always fixedly connected to the conductive plate 31 through the second conductive fixing seat 77. That is, the conductive connecting plate 78 and the conductive plate 31 always maintain a conductive connection. The flexible conductive strip 74 can bend and deform adaptively according to the distance between the two anode plates to maintain the conductive connection, achieve stable conductivity, and prevent power outages.

[0072] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0073] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
