[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Embodiment 1:

[0020] like Figure 1-2 As shown, Figure 1 This is a schematic diagram of the overall structure of a thin-walled hollow gravure cylinder electroplating device according to the first embodiment of the utility model. Figure 2 It is a structural schematic diagram of the rotating component of the first embodiment of the utility model.

[0021] The utility model provides an electroplating device for a thin-walled hollow gravure roller: comprising an electroplating pool 101 and a sliding plate 102, and also comprising a connecting device, wherein the connecting device comprises a fixed plate 105, a spring 106, a limit block 107, a conductive rod 108, a lifting cylinder 109 and a lifting assembly, wherein the lifting assembly comprises a rotating rod 110 and a rotating member, wherein the rotating member comprises a worm gear 111, a worm 112 and a rotating disk 113, and a conductive joint 114 is also provided on the conductive rod 108. The above-mentioned scheme solves the problem that when the roller in the above-mentioned device is installed, the roller is directly placed in the electroplating solution, and then the groove on the roller is engaged with the connecting assembly, which causes the electroplating solution to penetrate into the connection between the roller and the connecting assembly, thereby affecting the conductivity of the roller. It can be understood that the present scheme can also be used to solve the problem of replacing the electroplating solution.

[0022] In this embodiment, the roller is first connected to the conductive rod 108 and then immersed in the electroplating solution, thereby preventing the electroplating solution from penetrating into the connection between the roller and the limit block 107 .

[0023] Among them, the fixed plate 105 is fixedly installed on the sliding plate 102, the spring 106 is fixedly installed on the fixed plate 105, the limit block 107 is fixedly installed on the end of the spring 106 away from the fixed plate 105, the conductive rod 108 passes through the fixed plate 105 and the limit block 107, and is fixedly connected to the limit block 107, the lifting cylinder 109 is fixedly installed on the sliding plate 102, the lifting assembly is installed in the electroplating tank 101, and the electroplating tank 101 is provided with an electroplating liquid, both sides of the sliding plate 102 are provided with blocks 104, and the blocks 104 are respectively located in the slide grooves 103 on both sides, and the number of the fixed plate 105, the spring 106, the limit block 107 and the conductive rod 108 are all two groups, and are symmetrically distributed on the sliding plate 102. On both sides of the plate 102, the conductive rod 108 is a bent rod structure, the outside of the conductive rod 108 is wrapped with an insulating material (not shown in the figure), the axis of the spring 106 coincides with the horizontal end axis of the conductive rod 108, the cross-section of the limit block 107 is in the shape of a number three, the diameter of the limit block 107 is smaller than the diameter of the roller, and the interior of the lifting cylinder 109 is provided with a thread, which is driven by the elastic force of the spring 106 so that the limit block 107 clamps the roller and connects the conductive rod 108 to the roller, and then the lifting assembly cooperates with the lifting cylinder 109 so that the sliding plate 102 drives the connected roller to be immersed in the electroplating solution, thereby preventing the electroplating solution from being immersed in the connection between the roller and the limit block 107 by first connecting the roller to the conductive rod 108 and then immersing it in the electroplating solution.

[0024] Secondly, the rotating rod 110 is rotatably installed in the electroplating pool 101 and is threadedly connected to the lifting cylinder 109. The rotating component drives the rotating rod 110 to rotate. A thread is provided on the outer wall of the rotating rod 110. The rotating component drives the rotating rod 110 to rotate, so that the rotating rod 110 drives the lifting cylinder 109 to move up and down by cooperating with the thread of the lifting cylinder 109, thereby realizing the lifting and lowering of the lifting cylinder 109.

[0025] Again, the worm wheel 111 is fixedly mounted on the rotating rod 110; the worm 112 is rotatably mounted on the electroplating pool 101 and penetrates the electroplating pool 101, and the worm 112 is meshed with the worm wheel 111; the rotating disk 113 is rotatably mounted on the worm 112 and is located outside the electroplating pool 101, the worm 112 is mounted on the electroplating pool 101 through a bearing, the worm wheel 111 is perpendicular to the axis of the worm 112, the rotating disk 113 is welded to the worm 112, and the worm 112 is driven to rotate by rotating the rotating disk 113, the worm 112 is driven to rotate by meshing with the worm wheel 111, and the worm wheel 111 further drives the rotating rod 110 to rotate, thereby realizing the rotation of the rotating rod 110.

[0026] Finally, the conductive connector 114 is located at one end of the conductive rod 108 away from the fixing plate 105. The conductive connector 114 is made of copper. By setting the conductive connector 114, it is convenient to energize the conductive rod 108.

[0027] In this embodiment, when in use, the roller is placed between the limit blocks 107 on both sides, and driven by the elastic force of the spring 106, the limit blocks 107 on both sides clamp the roller. At this time, the end of the conductive rod 108 contacts the roller, and then the rotating disk 113 is rotated to drive the worm 112 to rotate. The worm 112 drives the rotating rod 110 fixedly connected to the worm wheel 111 to rotate by meshing with the worm wheel 111. The rotating rod 110 is threadedly matched with the lifting cylinder 109. The rotation of the movable rod 110 drives the lifting cylinder 109 to move downward. The movement of the lifting cylinder 109 enables the sliding block to drive the sliding plate 102 to move downward through the blocking block 104, and immerses the roller in the plating solution of the plating tank 101. Subsequently, the conductive connector 114 on the conductive rod 108 is connected to an external power supply to electroplate the roller. Thus, by first connecting the roller to the conductive rod 108 and then immersing it in the plating solution, the plating solution is prevented from being immersed in the connection between the roller and the limit block 107.

When the electroplating liquid needs to be replaced, the solenoid valve 202 controls the drain pipe 201 to guide the electroplating liquid out of the electroplating pool 101, thereby facilitating the replacement of the electroplating liquid.
