DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Embodiment 1:

[0034] In this embodiment, the electrophoretic paint is allowed to enter the channel 13 inside the second rotating rod 8 through the feeding pipe 9 and flow into the electrophoretic box 1, so as to facilitate the addition of the electrophoretic paint. Figure 1-Figure 2 and Figure 7 As shown:

[0035] The outer wall of the electrophoresis box 1 is provided with a fixing plate 2, a hydraulic rod 3 is installed on the fixing plate 2 by bolts, and the output end of the hydraulic rod 3 is connected to a mounting top plate 4, and a driving motor 5 is arranged above the mounting top plate 4;

[0036] The output end of the driving motor 5 is connected to a reciprocating screw rod 6, and the left and right sides of the reciprocating screw rod 6 are respectively provided with a first rotating rod 7 and a second rotating rod 8;

[0037] The first rotating rod 7 and the second rotating rod 8 are both provided with a channel 13, and the channel 13 and the feeding pipe 9 are connected to each other;

[0038] A sealing plug 14 is provided inside the channel 13 inside the second rotating rod 8, and the upper surface of the sealing plug 14 is connected to one end of the positioning rod 15, and the other end of the positioning rod 15 passes through a fixing block 16, the fixing block 16 is connected to the inner wall of the channel 13, and a through hole 18 is opened on the fixing block 16, and an elastic spring 17 is installed between the fixing block 16 and the positioning rod 15, and the through holes 18 are distributed at equal angles on the fixing block 16, the sealing plug 14 is made of rubber, the positioning rod 15 and the fixing block 16 are slidably connected, and the fixing block 16 and the channel 13 are bonded;

[0039] When using the metal processing bubble removal electrophoresis device, first place the electrophoresis box 1 in a corresponding position. Since the top ends of the first rotating rod 7 and the second rotating rod 8 are both equipped with a feeding tube 9, and the insides of the first rotating rod 7 and the second rotating rod 8 are both provided with a channel 13, and the channel 13 and the feeding tube 9 are interconnected, a sealing plug 14 is provided in the channel 13 inside the second rotating rod 8, and the sealing plug 14 is made of rubber, so the feeding tube 9 at the top end of the second rotating rod 8 can be connected to the external electrophoresis paint delivery pump, and the electrophoresis paint delivery pump can be connected to the feeding tube 9 at the top end of the second rotating rod 8. The delivery pump is started to deliver the electrophoretic material to the feeding pipe 9, and then the electrophoretic paint enters the channel 13 inside the second rotating rod 8 through the feeding pipe 9. Since the electrophoretic material has a certain impact force when being delivered, it will push the sealing plug 14 through the through hole 18 on the fixed block 16, and the sealing plug 14 will drive the positioning rod 15 to move together and stretch the elastic spring 17. When the sealing plug 14 and the channel 13 are separated, the electrophoretic paint flows out into the electrophoretic box 1, so that the feeding operation of the electrophoretic paint can be realized.

[0040] Embodiment 2:

[0041] In this embodiment, a defoaming agent is added from the feeding tube 9 at the top of the first rotating rod 7 to defoam the electrophoretic coating. Figure 3 , Figure 5-Figure 6 As shown:

[0042] The outer wall of the reciprocating screw rod 6 is connected with a placement plate 11 for placing metal workpieces;

[0043] The reciprocating screw rod 6, the first rotating rod 7 and the second rotating rod 8 are all connected to the mounting top plate 4 by bearings, and the bottom ends of the first rotating rod 7 and the second rotating rod 8 are spaced from the electrophoresis box 1;

[0044] The reciprocating screw 6 is connected to the first rotating rod 7 and the second rotating rod 8 by a transmission belt, and a feeding pipe 9 is provided at the top of the first rotating rod 7 and the second rotating rod 8, and a fixed blade 10 is installed on the outer wall of the first rotating rod 7 and the second rotating rod 8, and the feeding pipe 9 is connected to the first rotating rod 7 and the second rotating rod 8 by a bearing, and there is a gap between the fixed blade 10 and the placement plate 11;

[0045] After the addition of the electrophoretic paint is completed, the external delivery pump is turned off and the feeding operation is stopped. At this time, no paint will enter the channel 13 and there is no more driving force, so the elastic spring 17 will reset, and will drive the positioning rod 15 and the sealing plug 14 to rise together for reset. The sealing plug 14 will block the bottom of the channel 13 inside the second rotating rod 8, and then the staff will add the defoaming agent from the feeding pipe 9 at the top of the first rotating rod 7. The defoaming agent will enter the channel 13 inside the first rotating rod 7 through the feeding pipe 9, and flow into the electrophoretic box 1 to mix with the electrophoretic paint. At this time, the driving motor 5 is started, and the driving motor 5 will drive the reciprocating screw 6 to rotate. The reciprocating screw 6 drives the first rotating rod 7 and the second rotating rod 8 to rotate together through the transmission belt, so that the first rotating rod 7 and the second rotating rod 8 drive the fixed blade 10 to rotate, and the defoaming agent and the electrophoretic paint are stirred and mixed by the fixed blade 10. The rotation of the reciprocating screw 6 will drive the placement plate 11 to move up and down, which can effectively eliminate the bubbles in the electrophoretic paint, providing convenience for the subsequent electrophoretic processing of metal workpieces.

[0046] Embodiment three:

[0047] In this embodiment, after the stirring is uniform and the bubbles disappear, the metal workpiece is placed on the placement plate 11, and the placement plate 11 is lowered into the electrophoresis box 1 to perform electrophoresis processing on the metal workpiece. Figure 4 As shown:

[0048] The placement plate 11 is provided with a fixing hole 12, and the front and rear ends of the placement plate 11 are both in contact with the inner wall of the electrophoresis box 1, and the placement plate 11 and the reciprocating screw rod 6 are threadedly connected;

[0049] After stirring evenly and the bubbles disappear, start the hydraulic rod 3, which will push the installation top plate 4 to rise, and the installation top plate 4 will drive the reciprocating screw 6, the first rotating rod 7 and the second rotating rod 8 to rise together, so that the placement plate 11 connected to the outer wall of the reciprocating screw 6 will also rise and move out of the electrophoresis box 1, and then the metal workpiece to be processed will be placed on the placement plate 11, and then start the hydraulic rod 3 again, so that the hydraulic rod 3 drives the installation top plate 4 to descend, so that the metal workpiece on the placement plate 11 enters the electrophoresis box 1 for electrophoresis processing. Because the placement plate 11 is provided with a fixing hole 12, the electrophoretic coating will better contact the metal workpiece and improve the electrophoresis effect. The above is the working process of the entire device. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
