Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating technology, specifically to a rinsing device for electrophoretic coating. Background Technology

[0002] Electrophoretic coating is an immersion coating method in which metal workpieces are immersed in a water-soluble electrophoretic coating bath. Under the influence of an electric field, a uniform coating is deposited on the workpiece surface through reactions such as electrolysis, electrophoresis, electrodeposition, and electroosmosis. As a special type of immersion coating, some electrophoretic coating is inevitably carried away by the workpiece due to physical adsorption. In order to ensure a bright surface, this adhering electrophoretic coating must be rinsed off.

[0003] For example, utility model patent CN212293803U discloses a cleaning device for electrophoretic coating. This device cleans coated metal workpieces by spraying water, and can thoroughly clean even complex parts, greatly improving work efficiency. The electrophoretic paint recovery machine can also recover the backwashed electrophoretic paint and effectively filter and ultrafilter the treated wastewater, thus meeting relevant environmental protection requirements.

[0004] However, in actual use, after rinsing the workpiece, it cannot be dried, resulting in liquid residue on the workpiece surface, which is not conducive to the preservation of the workpiece, reduces the practicality of the device, and cannot well meet the usage requirements.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1-4 A rinsing device for electrophoretic coating includes: a rinsing table 1, on which a pair of rinsing racks 11 are installed; a moving mechanism 4, installed on the rinsing table 1, for moving the workpiece; a rinsing mechanism 2, installed inside the rinsing racks 11, for rinsing the workpiece; and a drying mechanism 3, installed inside the rinsing racks 11, for drying the rinsed workpiece.

[0023] The working principle of this utility model is as follows: In specific use, the workpiece is hooked on the moving mechanism 4, and the moving mechanism 4 drives the workpiece to move. When the workpiece moves to the rinsing mechanism 2, the rinsing mechanism 2 rinses the workpiece. After rinsing, the moving mechanism 4 drives the workpiece to continue moving, so that it moves to the drying mechanism 3. Then the drying mechanism 3 dries the rinsed workpiece, which can effectively reduce the residual liquid droplets on the surface of the workpiece, facilitate the subsequent storage of the workpiece, and better meet the usage requirements.

[0024] As a further embodiment, the moving mechanism 4 includes a moving frame 41 mounted on the washing table 1. A moving screw 43 is rotatably mounted on the moving frame 41, and a moving slide block 46 is slidably mounted on the moving frame 41. The moving slide block 46 is threaded onto the moving screw 43. A moving hanger 47 for hooking workpieces is also mounted at the lower end of the moving slide block 46. A moving pulley 44 is also mounted at the end of the moving screw 43. A moving belt 45 is fitted between the moving pulleys 44. A moving motor 42 is also mounted at the end of the moving frame 41. The output end of the moving motor 42 is drivenly connected to the shaft end of the moving screw 43. In this embodiment, multiple hanging holes for hooking workpieces are distributed on the moving hanger 47.

[0025] The working principle of the moving mechanism 4 is as follows: by hooking the workpiece onto the moving bracket 47, the moving motor 42 is started, and the moving screw 43 is rotated by the moving motor 42. Through the moving pulley 44 and the moving belt 45, the synchronous rotation of a pair of moving screws 43 can be achieved, thereby realizing the movement of the moving slide 46, which in turn drives the workpiece to move, making it convenient to wash and dry the workpiece.

[0026] As a further embodiment, the rinsing mechanism 2 includes rinsing seats 21 installed on opposite sides of the rinsing frame 11, each rinsing seat 21 being equipped with several rinsing nozzles, and a rinsing box 24 being provided at the lower end of the rinsing platform 1. A rinsing pipe 22 is installed on the rinsing box 24, and a rinsing branch pipe is installed at the end of the rinsing pipe 22. The output end of the rinsing branch pipe is connected to the corresponding rinsing seat 21, and a rinsing pump 23 is also installed on the rinsing pipe 22.

[0027] To facilitate the recovery of rinsing fluid, a return channel 26 is provided on the rinsing platform 1. Several return holes 27 are distributed in the return channel 26. A filter plate 25 is also installed on the upper part of the rinsing box 24. The filter plate 25 includes an activated carbon layer in the middle, and non-woven fabric layers are provided on both the upper and lower sides of the activated carbon layer.

[0028] The working principle of the rinsing mechanism 2 is as follows: During rinsing, the rinsing pump 23 is started, and the rinsing liquid in the rinsing tank 24 is transported to the rinsing pipe 22 through the rinsing pump 23. Then, it is transported to the corresponding rinsing seat 21 through the rinsing branch pipe. Then, it is sprayed out through the rinsing nozzle to rinse the workpiece. The rinsed liquid drips onto the filter plate 25 through the return hole 27 in the return tank 26. It is filtered by the filter plate 25, which can realize the reuse of the rinsing liquid.

[0029] As a further embodiment, the drying mechanism 3 includes multiple drying air knives 33 installed on opposite sides of the rinsing rack 11. The drying air knives 33 on each side are connected by drying branch pipes 34. A drying chamber 31 is also installed on the rinsing table 1, and a drying pipe 35 is installed on the drying chamber 31. The end of the drying pipe 35 is connected to the drying branch pipe 34, and a drying pump 32 is also installed on the drying pipe 35. In this embodiment, an electric heating wire is provided inside the drying chamber 31 to facilitate heating of the air inside the drying chamber 31.

[0030] The working principle of the drying mechanism 3 is as follows: the air in the drying chamber 31 is heated by the electric heating wire, and then the drying pump 32 is started. The air in the drying chamber 31 is transported to the drying air knife 33 through the drying pipe 35 and the drying branch pipe 34. The air is blown out by the drying air knife 33 to dry the workpiece. It can dry the droplets of residual liquid on the surface of the workpiece, which is convenient for subsequent storage.
