[0002] Electrophoretic coating is a special coating method in which the electrically conductive object to be coated is immersed as the anode in an electrophoresis coating tank filled with a relatively low-concentration electrophoresis coating diluted with water. Another cathode corresponding to it is arranged in the tank, and after direct current is applied between the two electrodes for a period of time, a uniform, fine and water-insoluble coating film is deposited on the surface of the object to be coated.

[0003] According to an electrophoresis tank disclosed in the patent application No. CN202020307081.0, it includes a tank body and a stirring mechanism and a cleaning mechanism fixed in the tank body.

A pull rope is connected to the middle of the cross beam, and the pull rope extends out of the tank body and is connected to the cover plate. The pull rope and the central axis of the stirring shaft are in the same plane.

[0004] Although the technical solution of the above patent can stir the electrophoresis coating with the stirring mechanism to avoid precipitation of the electrophoresis coating, the stirring chambers are arranged on both sides of the electrophoresis chamber, so that the flow rate of the paint near the stirring device is greater than that on the side far from the stirring device, resulting in different flow rates of the paint in the stirring chamber, thereby affecting the coating effect, and its stirring and mixing effect is poor. Therefore, we provide an electrophoresis tank for electrophoresis processing of metal parts to solve this problem. Content of the Utility Model

Detailed Description of the Preferred Embodiment

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 , an electrophoresis tank for electrophoretic processing of metal parts, comprising a tank body 1. A feeding mechanism 2 is installed in the inner cavity of the tank body 1. The feeding mechanism 2 includes a servo motor 21 installed outside the tank body 1. The output end of the servo motor 21 penetrates the tank body 1 and is connected to a lead screw 22. A threaded block 23 is screwed on the outer side of the lead screw 22. The lower end of the threaded block 23 is connected to a cross bar 24. The lower end of the cross bar 24 is equidistantly connected with pushing blocks 25. Both sides of the pushing block 25 are curved surfaces, and arc-shaped grooves 27 are arranged on both sides of the cross bar 24. Arc-shaped strips 4 which are slidably connected therewith are arranged on both sides of the inner cavity of the tank body 1.

[0026] The output end of the servo motor 21 drives the lead screw 22 to rotate, and the threaded block 23 on the outer side of the lead screw 22 moves back and forth accordingly. The threaded block 23 synchronously drives the cross bar 24 and a plurality of pushing blocks 25 at its lower end to move. The cross bar 24 stably slides outside the arc-shaped strip 4 through the arc-shaped groove 27, effectively improving the stability of the reciprocating movement of the cross bar 24. And the pushing blocks 25 with curved surfaces on both sides effectively scrape the paint deposited at the bottom end of the inner cavity of the tank body 1. After the pushing blocks 25 repeatedly push horizontally, the deposited paint begins to roll up, which is convenient for avoiding accumulation and caking and affecting the use.

[0027] Spraying mechanisms 3 are installed on both sides of the tank body 1. The spraying mechanisms 3 penetrate the tank body 1 and extend into its inner cavity; mounting holes 5 are arranged on both sides of the bottom end of the tank body 1. The mounting holes 5 are L-shaped. The spraying mechanism 3 includes a material suction pipe 34 hermetically bonded to the inner cavity of the mounting hole 5. One ends of the three material suction pipes 34 are all connected to a first fixing pipe 33. The first fixing pipes 33 are all connected to a pump body 31 through a first conveying pipe 32. The upper end of the pump body 31 is connected to two third conveying pipes 36 through a second conveying pipe 35. A second fixing pipe 37 is installed on the outer side of the third conveying pipe 36. The second fixing pipe 37 and the first fixing pipe 33 are both installed on the outer side of the tank body 1 through a mounting sleeve 38. Spray pipes 39 are equidistantly connected to the outer side of the second fixing pipe 37. One ends of the spray pipes 39 all penetrate the tank body 1 and extend into its inner cavity.

[0028] By starting the pump body 31, the pump body 31 then extracts the tumbling and lifted paint through the material extraction pipe 34. The material extraction pipe 34 transports the paint through the first fixed pipe 33 and the first delivery pipe 32 to the pump body 31. Subsequently, the pump body 31 transports the paint through the second delivery pipe 35 to two third delivery pipes 36. Finally, the two third delivery pipes 36 transport the paint through the second fixed pipe 37 to multiple spray nozzles 39 and then spray it out through the spray nozzles 39, which facilitates the reverse transportation of the precipitated paint at different heights of the paint liquid level in the tank body 1, facilitates the circulation of the paint liquid inside the tank body 1, improves the uniformity of the paint ions, and facilitates the improvement of the effect of electrophoretic coating of workpieces.

[0029] At the upper end of the cross bar 24, tooth blocks 26 are symmetrically connected. On both sides of the inner cavity of the tank body 1, pushing components are installed, and the tooth blocks 26 are all meshed and connected with the pushing components. The pushing components include four groups of rotating shafts 6 rotatably installed on the inner wall of the tank body 1. On the outer sides of the rotating shafts 6, first gears 7 are connected. A double-sided toothed belt 8 is commonly meshed and sleeved on the outer sides of the four groups of first gears 7. On both sides of the tank body 1, support shafts 9 are rotatably connected. On the outer sides of the support shafts 9, second gears 10 meshing with the inner side of the double-sided toothed belt 8 are installed. On the outer sides of the support shafts 9, cams 11 are installed. The tooth blocks 26 are meshed with the outer side of the double-sided toothed belt 8.

[0030] In the inner cavity of the tank body 1, fixing frames 314 corresponding to the positions of the spray nozzles 39 are equidistantly installed. On both sides of the fixing frames 314, sliding grooves 315 are provided. The spray nozzles 39 are all connected with spray heads 311 through hoses 310. On the outer sides of the spray heads 311, fixing sleeves 312 are installed. On both sides of the fixing sleeves 312, sliding columns 313 slidably connected with the sliding grooves 315 are connected.

[0031] A connecting column 316 is commonly connected between every two fixing sleeves 312, and the lower ends of the four groups of fixing sleeves 312 are commonly connected with a bottom plate 318 through a connecting rod 317. The bottom plate 318 is located above the cam 11.

[0032] When the cross bar 24 reciprocates, the tooth block 26 at the upper end of the cross bar 24 meshes with the double-sided toothed belt 8 for transmission, thereby driving the double-sided toothed belt 8 to rotate. Then, the second gear 10 meshed with the inner side of the double-sided toothed belt 8 rotates accordingly. Further, the second gear 10 drives the support shaft 9 and the cam 11 to rotate. Subsequently, the cam 11 intermittently jacks up the bottom plate 318 upwards. The bottom plate 318 synchronously drives a row of fixed sleeves 312 and the spray heads 311 in their inner cavities to move upwards through the connecting rod 317. All the fixed sleeves 312 in this row are connected to other fixed sleeves 312 through the connecting columns 316. Further, another row of fixed sleeves 312 synchronously drives the spray heads 311 to move upwards. The fixed sleeves 312 all slide stably in the inner cavity of the sliding groove 315 through the sliding columns 313, facilitating the stable up and down movement of multiple spray heads 311, facilitating the further increase of the reverse jet flow area of the precipitation coating, improving the coating liquid circulation efficiency inside the tank body 1, thereby rapidly improving the uniformity of coating ions, and further increasing the effect of electrophoretic coating of workpieces.

[0033] Working principle: The utility model is controlled and connected with the servo motor 21 and the pump body 31 through an external controller. When in use, the output end of the servo motor 21 drives the screw rod 22 to rotate, and the threaded block 23 outside the screw rod 22 moves back and forth accordingly, and the threaded block 23 synchronously drives the cross bar 24 and the multiple push blocks 25 at its lower end to move. The push blocks 25 with curved surfaces on both sides are effectively pushed and scraped to push the paint deposited at the bottom of the inner cavity of the tank body 1, so that after repeated horizontal pushing of the push blocks 25, the deposited paint begins to turn over. The cross bar 24 is rolled up to avoid accumulation and caking, which affects its use. When the cross bar 24 moves back and forth, the tooth block 26 at the upper end of the cross bar 24 engages with the double-sided toothed belt 8 for transmission, thereby driving the double-sided toothed belt 8 to rotate, and the second gear 10 meshing with the inner side of the double-sided toothed belt 8 rotates accordingly, and then the second gear 10 drives the support shaft 9 and the cam 11 to rotate, and then the cam 11 intermittently pushes up the bottom plate 318, and the bottom plate 318 synchronously drives a row of fixed sleeves 312 and the nozzle 311 of the inner cavity thereof through the connecting rod 317. The fixing sleeves 312 in one row are connected to other fixing sleeves 312 through connecting posts 316, and then the fixing sleeves 312 in another row synchronously drive the nozzles 311 to move upward, and the fixing sleeves 312 are stably slid in the inner cavity of the slide groove 315 through the sliding posts 313, so that the multiple nozzles 311 can move up and down stably, so as to further increase the area of the reverse jet of the precipitated paint, and by starting the pump body 31, the pump body 31 extracts the tumbling paint through the extraction pipe 34, and the extraction pipe 34 passes the paint through the nozzle 311. The paint is transported to the pump body 31 through the first fixed pipe 33 and the first delivery pipe 32, and then the pump body 31 delivers the paint to the two third delivery pipes 36 through the second delivery pipe 35. Finally, the two third delivery pipes 36 deliver the paint to multiple nozzles 39 through the second fixed pipe 37, and then sprayed out through the nozzle 311, so as to facilitate the reverse delivery of the precipitated paint at different heights of the paint liquid level in the pool body 1, facilitate the circulation of the paint liquid inside the pool body 1, improve the uniformity of the paint ions, and improve the effect of electrophoretic coating of the workpiece.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
