Description

Technical Field

[0001] This utility model relates to the field of printing roller processing technology, and in particular to a chromium groove anode reinforcement device. Background Technology

[0002] During the manufacturing process, printing rollers require chrome plating. A chrome plating bath is used for this process. Currently, the anodes in the chrome plating bath are made of lead-tin alloy, which are consumed during use, softening and deforming. This deformation causes changes in the distance between the anode and the printing roller during the plating process. These changes in distance result in different chrome plating layers, affecting product quality.

[0003] Patent document CN206783767U discloses a chromium removal device for printing rollers. The technical solution includes an inner groove and an outer groove, with the inner groove placed inside the outer groove and not communicating with it. The inner groove is characterized by two parallel and spaced-apart drive rollers A and B, driven by a motor to rotate in the same direction. The chromium removal roller is placed on top of the two drive rollers, completely submerged in the chromium removal solution within the inner groove, and rotates accordingly, thus achieving automatic chromium removal from the printing roller. In this solution, the rotation of the drive rollers in the same direction drives the printing roller to rotate, achieving automatic chromium removal. This eliminates the need to change clamps during printing roller processing, saving manpower and time.

[0004] In the above scheme, the device is suitable for chromium removal from printing rollers. However, the anodes of existing printing roller chromium plating devices are usually not equipped with reinforcement devices. After long-term use, the accuracy of the printing roller cannot be guaranteed, and the anodes need to be replaced frequently, resulting in poor economic benefits and a poor printing roller yield. Therefore, it is necessary to provide a chromium tank anode reinforcement device to solve the shortcomings of the existing technology. Utility Model Content

[0025] Example 1:

[0026] In this embodiment, as Figure 1-3 As shown, the present invention proposes a chromium tank anode reinforcement device, including an outer tank 1 and an inner tank 2.

Through hole group one, through hole group two and through hole group three are provided correspondingly, and the bolt passes through through hole group three, through hole group one and through hole group two in sequence to connect with the inner groove.

[0029] In this example, each of the three through-hole groups has three through holes. Since each through-hole group has three through holes, the connection strength is relatively high.

[0030] In this embodiment, the reinforcement component is further configured to include a first reinforcement plate 53, a second reinforcement plate 54, and a third reinforcement plate 55. The first reinforcement plate is located below the main board, the first reinforcement plate is connected to the top of the curved surface, the second reinforcement plate is connected to the middle of the curved surface, and the third reinforcement plate is connected to the bottom of the curved surface.

[0031] In this example, the position of the curved surface can be better defined by the reinforcement plate one, reinforcement plate two, and reinforcement plate three, resulting in better structural strength and overall stability of the fixing frame, thereby better defining the position of the lead anode and reducing deformation of the lead anode during use.

The lead-tin alloy anode has corrosion resistance, which can reduce anode wear and extend its service life.

[0037] Example 2:

[0038] In this embodiment, as Figure 1-3As shown, the present invention proposes a chromium tank anode reinforcement device, including an outer tank 1 and an inner tank 2. The inner tank is installed inside the outer tank. The inner tank is provided with a first transmission roller 3 and a second transmission roller 4. A printing roller is loaded between the first transmission roller 1 and the second transmission roller 2. The printing roller is not shown in the figure. Fixing frames 5 are symmetrically installed on both sides of the inner tank. Lead anodes are arrayed on the fixing frames. The fixing frames can connect to the inner tank and provide space for the lead anodes to be installed. The lead anodes can be fixedly installed on the fixing frames by bolts.

[0039] The mounting bracket includes a main board 51, a curved surface 52, and a reinforcement component. The top of the back of the main board is connected to the top of the front of the curved surface, and the back of the curved surface is connected to the front of the reinforcement component.

[0040] In this example, there is one mainboard, which is 3310mm long and 100mm wide, and five curved strips, each 60mm wide.

[0041] In this embodiment, the main board array is further configured to have a through hole group one, the top of the curved surface is provided with a through hole group two, and the top of the lead anode is provided with a through hole group three. Through hole group one, through hole group two and through hole group three are provided correspondingly, and the bolt passes through through hole group three, through hole group one and through hole group two in sequence to connect with the inner groove.

[0042] In this example, each of the three through-hole groups has three through holes. Since each through-hole group has three through holes, its connection strength is high, and the total number of groups is 26.

[0043] In this embodiment, the reinforcement component is further configured to include a first reinforcement plate 53, a second reinforcement plate 54, and a third reinforcement plate 55. The first reinforcement plate is located below the main board, the first reinforcement plate is connected to the top of the curved surface, the second reinforcement plate is connected to the middle of the curved surface, and the third reinforcement plate is connected to the bottom of the curved surface.

[0044] In this example, the lengths of reinforcing plates one, two, and three are all 3310mm, the widths of reinforcing plates one and two are 50mm, and the width of reinforcing plate three is 40mm. Reinforcing plates one, two, and three can better define the position of the curved surface, resulting in better structural strength and overall stability of the fixing frame, thereby better defining the position of the lead anode and reducing deformation of the lead anode during use.

[0045] In this embodiment, the reinforcement plate two array is provided with through hole one, the reinforcement plate three array is provided with through hole two, the lead anode is provided with through hole three in the middle, and the lead anode is provided with through hole four at the bottom.

Through hole two and through hole four are provided correspondingly. Bolts pass through through hole four and through hole two in sequence to connect the lead anode to the reinforcement plate three.

[0046] The working principle of this chromium tank anode reinforcement device is as follows: Since the lead anodes are directly installed on the inner tank, they will be consumed, soften, and deform during use. As a result, the distance between the lead anodes and the printing roller will change during the plating process. The change in distance will result in different chromium layers, affecting product quality. Now, the lead anode array is installed on a fixed frame, and the lead anodes are limited at multiple points. The fixed frame is then installed on the inner tank, replacing the direct installation of the lead anodes on the inner tank. This reduces and avoids deformation of the lead anodes during use, thereby improving the precision of the printing roller and enhancing product quality.
