[0029] Two stirring shafts 2 are rotatably installed on the inner side of the stirring box 1, and the stirring box 1 is used to support the stirring shafts 2. When the electroplating paint is stirred, the stirring box 1 can also hold the liquid raw materials that need to be mixed. When the stirring shaft 2 rotates, it can drive the stirring teeth 3 on the outside to rotate synchronously, so that the raw materials in the stirring box 1 can be stirred and mixed; a number of stirring teeth 3 are welded on the outside of the two stirring shafts 2, and when the stirring shaft 2 rotates, it can drive the stirring teeth 3 on the outside to rotate synchronously, so that the raw materials in the stirring box 1 can be stirred and mixed; a stirring shaft support ring 4 is provided on the outside of the right end of the two stirring shafts 2, and the stirring shaft support ring 4 and the rectangular plate on the outside of the stirring box 1 can close the circular hole and the long strip hole on the right outer wall of the stirring box 1 when the stirring shaft 2 is pushed to the leftmost side, so that the stirring box 1 can hold the liquid raw material, avoiding the raw material from being stirred during the stirring process. Flow outward; a guide bracket 5 is arranged on the outer side of the two stirring shaft support rings 4, and the guide bracket 5 is used to support the stirring shaft support ring 4 and the motor support plate 6. When the stirring shaft 2 is pushed left and right and adjusted, the guide bracket 5 will slide left and right synchronously under the support of the guide rail 8, thereby ensuring the stability of the stirring shaft 2 when it is displaced left and right and avoiding its tilting; a motor support plate 6 is arranged at the bottom of the guide bracket 5, and the motor support plate 6 is used to support the motor 7; two motors 7 are installed on the top of the motor support plate 6, and one end of the main shaft of the two motors 7 is fixedly connected to the right end of the two stirring shafts 2 respectively. When using this device to stir the raw materials, the two motors 7 can be powered on and turned on, and the two motors 7 can be rotated in different directions, so that the two stirring shafts 2 can be driven to rotate in the opposite direction, so that the stirring of the raw materials will be more uniform; a set of guide rails 8 are arranged on the front and back sides of the mixing box 1, and the guide rails 8 are used to support and guide the guide bracket 5.

[0030] In the present disclosure, Figure 1 , Figure 2 and Figure 5 As shown, a group of horizontal rectangular plates and two groups of vertical rectangular plates are arranged on the outside of the stirring shaft support ring 4, and when the stirring shaft 2 is pushed to the extreme left, these rectangular plates on the outside of the stirring shaft support ring 4 will block the long strip holes on the right outer wall of the stirring box 1. When the stirring shaft 2 is pushed to the extreme left, the stirring shaft support ring 4 and the rectangular plates on its outside can close the circular holes and the long strip holes on the right outer wall of the stirring box 1, so that the stirring box 1 can hold the liquid raw material and prevent the raw material from flowing out during the stirring process.

[0031] In the present disclosure, Figure 1 , Figure 2 and Figure 4As shown, the stirring teeth 3 are all rectangular plates, and the stirring teeth 3 on the two stirring shafts 2 are staggered. Two circular holes with an inner diameter equal to the outer diameter of the stirring shaft 2 are arranged on the right outer wall of the stirring box 1. A group of horizontal long strip holes and two groups of vertical long strip holes are also arranged on the outside of the two circular holes. The stirring teeth 3 can slide left and right in these long strip holes and cling to the inner walls of the long strip holes. When it is necessary to clean the raw materials adhered to the stirring shaft 2 and the stirring teeth 3, first rotate the stirring teeth 3 on the outside of the stirring shaft 2 to the right side of the stirring box 1. The long strip holes on the outer wall are aligned, and then the guide bracket 5 is pushed to the right with the support of the guide rail 8. During this process, the stirring shaft 2 and the stirring tooth 3 will also move to the right synchronously, and then the stirring shaft 2 will pass through the circular hole on the right side of the mixing box 1 and fit tightly against the inner wall of the circular hole, so the raw materials on the outer wall of the stirring shaft 2 can be scraped off, and the stirring tooth 3 will pass through the long strip hole on the right side of the mixing box 1 and fit tightly against the long strip inner wall, so the raw materials on the outer wall of the stirring tooth 3 will also be scraped off. Finally, you only need to clean out the raw materials scraped on the inner wall on the right side of the mixing box 1.

[0032] In the present disclosure, Figure 1 and Figure 2 As shown, a rectangular groove is provided between the guide rails 8, and the height of the rectangular groove is equal to the thickness of the guide bracket 5. When the stirring shaft 2 is pushed left and right for adjustment, the guide bracket 5 will slide left and right synchronously under the support of the guide rail 8, thereby ensuring the stability of the stirring shaft 2 when it is displaced left and right and avoiding its tilting.

[0033] In the present disclosure, Figure 3 As shown, two hemispherical protrusions are provided on the left inner wall of the mixing box 1, and a corresponding hemispherical groove is provided on the left end of the mixing shaft 2. When the mixing shaft 2 is pushed to the extreme left, the hemispherical protrusion on the inner wall of the mixing box 1 will be embedded in the hemispherical groove at the left end of the mixing shaft 2. When the mixing shaft 2 is pushed to the extreme left, the hemispherical protrusion on the left inner wall of the mixing box 1 and the hemispherical groove at the left end of the mixing shaft 2 can cooperate to support the left end of the mixing shaft 2, so that the mixing shaft 2 can rotate stably when stirring the raw materials.

[0034] In the present disclosure, Figure 1 and Figure 2 As shown, a protrusion is provided on the front and rear sides of the left side of the guide bracket 5, and a raised baffle is provided on the outer side of the guide rail 8. When the stirring shaft 2 moves to the rightmost side, the protrusions on the front and rear sides of the guide bracket 5 will be tightly attached to the left side surface of the raised baffle on the outer side of the guide rail 8, so when the stirring shaft 2 is pushed to the right, the guide bracket 5 can be prevented from being separated from the guide rail 8.

[0035] In the present disclosure, Figure 6As shown, an annular inner groove is provided on the outer side of the right end of the stirring shaft 2, and the stirring shaft support ring 4 is installed in the annular inner groove, and the width of the stirring shaft support ring 4 is equal to the width of the annular inner groove, and the outer diameter of the stirring shaft support ring 4 is equal to the outer diameter of the stirring shaft 2, so the stirring shaft 2 can rotate under the support of the stirring shaft support ring 4, and the stirring shaft support ring 4 can also ensure that the circular hole on the right outer wall of the stirring box 1 is closed.

[0036] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6 As shown, the outer wall of the stirring shaft support ring 4 and the rectangular plate on its outer side can also be wrapped with a layer of rubber. Therefore, when the stirring shaft 2 is pushed to the extreme left, the stirring shaft support ring 4 and the rectangular plate on its outer side can close the circular holes and the long strip holes on the right outer wall of the stirring box 1, so these rubbers will also be located in the circular holes and the long strip holes on the right outer wall of the stirring box 1, thereby improving the sealing and friction.

[0037] The working principle of this embodiment is as follows: when in use, first place the mixing box 1 on the ground, and then push the mixing shaft 2 to the left to the extreme left. When the mixing shaft 2 is pushed to the extreme left, the hemispherical protrusion on the left inner wall of the mixing box 1 cooperates with the hemispherical groove on the left end of the mixing shaft 2 to support the left end of the mixing shaft 2, so that the mixing shaft 2 can rotate stably when the raw materials are stirred, and when the mixing shaft 2 is pushed to the extreme left, the mixing shaft support ring 4 and the rectangular plate on the outside thereof can close the circular hole and the long strip hole on the right outer wall of the mixing box 1, so that the mixing box 1 can hold the liquid raw material to prevent the raw material from flowing out during the stirring process. When stirring and mixing the electroplating paint, first pour the liquid raw material into the mixing box 1, and then turn on the two motors 7, and make the two motors 7 rotate in different directions, so that the two stirring shafts 2 can be driven to rotate in opposite directions. When the stirring shaft 2 rotates, the stirring teeth 3 on the outside thereof can be driven to rotate synchronously, so that the raw materials in the mixing box 1 can be stirred and mixed. After the stirring is completed, the motor 7 is first powered off and then the electroplating paint is led out;

[0038] When it is necessary to clean the raw materials adhered to the stirring shaft 2 and the stirring teeth 3, first rotate the stirring teeth 3 on the outside of the stirring shaft 2 until they are aligned with the long strip hole on the right outer wall of the stirring box 1, and then push the guide bracket 5 to the right with the support of the guide rail 8. During this process, the stirring shaft 2 and the stirring teeth 3 will also move to the right synchronously, and then the stirring shaft 2 will pass through the circular hole on the right side of the stirring box 1 and fit tightly against the inner wall of the circular hole, so the raw materials on the outer wall of the stirring shaft 2 can be scraped off, and the stirring teeth 3 will pass through the long strip hole on the right side of the stirring box 1 and fit tightly against the long strip inner wall, so the raw materials on the outer wall of the stirring teeth 3 will also be scraped off. Finally, you only need to clean the raw materials scraped on the right inner wall of the stirring box 1 outwards, and the inside of the stirring box 1 can also be cleaned at this time.
