Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and more specifically, to an industrial electrolytic phosphating tank. Background Technology

[0002] When performing phosphating treatment on workpieces, it is usually necessary to immerse the workpiece in a phosphating tank containing phosphating solution. Traditional phosphating operations involve clamping the workpiece on a fixture, and then using lifting equipment to move the fixture and the workpiece together into the phosphating tank for immersion. Because there is no device on the phosphating tank to agitate the phosphating solution, the concentration of the phosphating solution near the workpiece decreases after a certain reaction time, failing to meet the original phosphating requirements, slowing down the reaction, severely affecting the quality of the phosphating layer, and resulting in poor overall performance. Therefore, this utility model proposes an industrial electrolytic phosphating tank. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an industrial electrolytic phosphating cell that features balanced concentration, sufficient reaction, and high-quality phosphating layer.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: This utility model relates to an industrial electrolytic phosphating tank, comprising a phosphating tank body and a phosphating roller disposed within the phosphating tank body. The phosphating roller has roller shafts at both ends, a first gear on each roller shaft, and a second gear meshing with the first gear below it. The second gear is rotatably connected to the phosphating tank body. A lower sprocket, rotating synchronously, is coaxially mounted on the second gear. An upper sprocket, rotatably connected to the phosphating tank body, is located above the lower sprocket. A chain drives between the upper sprocket and the lower sprocket. A power assembly controlling the rotation is driven onto the upper sprocket. A partition is provided between the phosphating roller and the first gear. A limiting groove, with its upper end connected to the outside and extending vertically, is opened on the partition. The roller shaft slides down into the limiting groove from top to bottom.

[0005] The present invention is further configured such that the partition plate is connected to the phosphating tank body by a bracket.

[0006] The present invention is further configured such that the lower sprocket is located between the tank wall of the phosphating tank body and the second gear.

[0007] The present invention is further configured such that the upper end of the limiting groove has a flared opening.

[0008] The present invention is further configured such that the powertrain includes a motor and a reducer.

[0009] In summary, this utility model has the following beneficial effects:

[0010] 1. A set of gears drives the installed phosphating roller to rotate within the phosphating tank, disturbing the phosphating solution while the internal workpieces also tumble, achieving full contact and reaction with the phosphating solution, resulting in balanced concentration, thorough reaction, and high-quality phosphating layer.

[0011] 2. By using a set of sprockets, the motor is mounted on top, eliminating the need to drill holes in the wall of the phosphating tank. Otherwise, the sealing of the holes would need to be considered, reducing the manufacturing difficulty of the phosphating tank. Attached Figure Description

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See Figure 1 and Figure 2 As shown, the industrial electrolytic phosphating tank involved in this embodiment includes a phosphating tank body 1 and a phosphating roller 2 disposed inside the phosphating tank body. The two ends of the phosphating roller 2 are respectively provided with roller shafts 3. A first gear 4 that follows the movement is provided on the roller shaft 3. A second gear 5 that meshes with the first gear 4 is provided below the first gear 4. The second gear 5 is rotatably connected to the phosphating tank body 1. A lower sprocket 6 that rotates synchronously is provided on the second gear 5 along the same axis. An upper sprocket 7 that is rotatably connected to the phosphating tank body 1 is provided above the lower sprocket 6. A chain 8 is transmitted between the upper sprocket 7 and the lower sprocket 6. A power assembly 9 that controls the rotation is transmitted to the upper sprocket 7. The power assembly 9 includes a motor and a reducer. A partition 10 is provided between the phosphating roller 2 and the first gear 4. A limiting groove 11 that is connected to the outside at the top and extends vertically is opened on the partition 10. The roller shaft 3 slides down into the limiting groove 11.

[0018] Furthermore, the partition 10 is connected to the phosphating tank body 1 via a bracket 12.

[0019] Furthermore, the lower sprocket 6 is located between the tank wall of the phosphating tank body 1 and the second gear 5.

[0020] In this embodiment, the phosphating roller 2, which carries the roller shaft 3 and the first gear 4, is installed into the phosphating tank body 1. The roller shaft 3 slides into the bottom along the limiting groove 11. When the roller shaft 3 reaches the bottom, the first gear 4 just meshes with the second gear 5. At this time, the upper sprocket 7 is driven to rotate by the power assembly 9. The second gear 5 rotates through the chain 8 and the lower sprocket 6. Then, through the gear transmission, the first gear 4 drives the phosphating roller 2 to rotate in the phosphating tank body 1 containing the phosphating liquid.

[0021] Example 2

[0022] See Figure 1 and Figure 2 As shown, the industrial electrolytic phosphating cell involved in this embodiment is further configured, based on embodiment 1, with the upper end of the limiting groove 11 having a flared opening (not marked).

[0023] In this embodiment, a flared structure is provided at the upper end of the limiting groove 11 as an installation guide, which facilitates the roller shaft 3 to move down along the limiting groove 11 until the two gears mesh.

[0024] The industrial electrolytic phosphating tank involved in this utility model uses a set of gear mechanisms to drive the phosphating roller installed in place to rotate within the phosphating tank body. While disturbing the phosphating solution, the internal workpiece also tumbles, achieving the effect of full contact and reaction with the phosphating solution, resulting in uniform concentration, sufficient reaction, and high-quality phosphating layer. Furthermore, a set of sprocket mechanisms allows the motor to be mounted on top, eliminating the need to drill holes in the wall of the phosphating tank body. Otherwise, the sealing of the hole would need to be considered, reducing the manufacturing difficulty of the phosphating tank. Overall, the function is complete and the practicality is strong.
