[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides Figure 1-4 The electrophoretic coating device of a trailer traction seat shown in the figure comprises an electrophoretic box 1 and an electrophoretic liquid replacement mechanism 2. The inner side wall of the electrophoretic box 1 is fixedly connected with a bottom plate 101 for dividing the inner cavity of the electrophoretic box 1 into an upper and lower layer, thereby facilitating subsequent filtering. The electrophoretic liquid replacement mechanism 2 comprises two groups of leakage holes 201 opened on the surface of the bottom plate 101, so that the electrophoretic liquid of the upper layer inside the electrophoretic box 1 can flow into the lower layer. A plurality of groups of filter holes 202 are arranged below the leakage holes 201 and the filter holes 202 are opened on the bottom wall of the electrophoretic box 1. One end of the filter hole 202 close to the outer side of the electrophoretic box 1 is bolted with a coarse filter screen 206, and the electrophoretic liquid is coarsely filtered through the coarse filter screen 206. The filter hole 202 close to the coarse filter screen 20 One end of 6 is connected with a side cavity 205 for storing electrophoresis liquid, a pipette 203 is arranged inside the side cavity 205 and a water-permeable membrane 207 is installed at the bottom end of the pipette 203, secondary filtration is performed through the water-permeable membrane 207, the top end of the pipette 203 is connected with a water pump 9, the water pump 9 is installed on the outside of the electrophoresis box 1, one end of the water pump 9 is fixedly connected with a transfer tube 7, the electrophoresis liquid filtered from the side cavity 205 is sucked out by the cooperation of the water pump 9 and the pipette 203, the top end of the transfer tube 7 is fixedly connected with a liquid storage tank 6, one side of the liquid storage tank 6 is connected with a liquid outlet pipe 204 and the liquid outlet pipe 204 is opened on the inner wall of the electrophoresis box 1, and the pure electrophoresis liquid is re-injected into the interior of the electrophoresis box 1 through the liquid storage tank 6.

[0024] like Figure 1-4 As shown, the outer wall of the electrophoresis box 1 is fixedly connected with several groups of replacement doors 8, and the replacement door 8 is communicated with the side cavity 205. An inspection door 10 is provided at one end of the electrophoresis box 1, and the side cavity 205 and the inner cavity of the electrophoresis box 1 are cleaned by using the replacement door 8 and the inspection door 10. A fixed platform 3 is provided on the top of the electrophoresis box 1, and a cylinder 4 is installed on the top of the fixed platform 3. The output end of the cylinder 4 is fixedly connected with a mounting frame 5, and the mounting frame 5 slides on the outer wall of the fixed platform 3. The mounting frame 5 can be installed with a trailer traction seat. When the traction seat needs to be electrophoretically coated, the cylinder 4 is started to drive the mounting frame 5 to rise and fall, which can drive the trailer traction seat to sink into or out of the electrophoresis liquid.

[0025] like Figure 1-4 As shown, a servo motor 14 is installed on one side of the electrophoresis box 1, and a threaded rod 13 is fixedly connected to the output end of the servo motor 14. Two sets of blocking plates 11 are threadedly connected to the outer side of the threaded rod 13. The threads on both sides of the threaded rod 13 are in opposite directions. The inside of the blocking plate 11 is wrapped with a sliding rod 12, and the sliding rod 12 is fixedly connected to the inner wall of the electrophoresis box 1. The sliding rod 12 limits the movement path of the blocking plate 11, so that it can prevent the liquid above the leakage hole 201 from falling into the lower layer. The blocking plate 11 slides on the outside of the sliding rod 12, and the movement of the blocking plate 11 is driven by the servo motor 14, so that the blocking plate 11 can block or dredge the leakage hole 201 according to the working conditions.

[0026] How this utility works:

[0027] Refer to the instruction manual Figure 1-4 When the trailer traction seat needs to be electrophoretically coated, the trailer traction seat is installed under the mounting frame 5, and then the cylinder 4 is started to make the mounting frame 5 drive the trailer traction seat to sink into the electrophoresis box 1 to work. After the work is completed, the servo motor 14 is started to drive the threaded rod 13 to rotate, and the blocking plate 11 is gathered by using two sets of opposite threads on the surface of the threaded rod 13 so that the electrophoresis liquid can leak from the inside of the leakage hole 201 to the lower layer of the bottom plate 101, and the large particles of impurities are intercepted by the cooperation of the filter hole 202 and the coarse filter 206, and the coarsely filtered electrophoresis liquid enters the side cavity 205, and then under the action of the water pump 9, it is further filtered through the water permeable membrane 207 and enters the suction pipe 203, the transfer pipe 7 and the liquid storage. Inside the tank 6, since the water-permeable membrane 207 only allows liquid to pass through, the flow rate is slow, and part of the electrophoretic liquid will be stored in the liquid storage tank 6 in advance. Through the cooperation of the liquid outlet pipe 204, the electrophoretic liquid in the electrophoretic box 1 is automatically replenished when the water level drops, thereby not affecting the working hours of painting, and when the next set of trailer traction seats arrives, the servo motor 14 is restarted to drive the threaded rod 13 to rotate, so that the blocking plate 11 is reset to prevent the electrophoretic liquid in the electrophoretic box 1 from continuing to flow down, so that the purification of the electrophoretic liquid and the electrophoretic coating work do not interfere with each other, thereby realizing the recycling of the electrophoretic liquid, and avoiding the resin and other pigment particles from being easily accumulated at the bottom of the tank body to affect the covering speed and coating quality of the traction seat surface, and saving costs.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
