For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] Please see Figures 1 to 6This utility model provides a technical solution: a paint mixing device, including a mixing chamber 1, a mounting box 4 is fixedly installed on the side of the mixing chamber 1 by a fixing rod 3, and the mounting box 4 can be opened as a whole. A motor 11 is fixedly installed on the side wall of the mounting box 4. A disc 13 is fixedly connected to the output shaft of the motor 11. One end of a small cylinder 14 is fixedly connected to the side of the disc 13 away from the motor 11. The motor 11 drives the disc 13 at its output end to rotate, and the disc 13 drives the small cylinder 14 to rotate. Then, the small cylinder 14 drives the connecting rod 15 connected to its end to rotate. Through the action of the disc 13, the connecting rod 15 can form a certain movement trajectory, which is convenient for subsequent use.
[0025] In this embodiment, please refer to Figure 4 and Figure 6 The upper semicircular cover 17 is fixedly connected to the end of the connecting rod 15. The lower semicircular cover 18 is detachably installed at the bottom of the upper semicircular cover 17. The round head 26 is rotatably installed using the upper semicircular cover 17 and the lower semicircular cover 18. The round head 26 can also rotate at multiple angles. The threaded rod 20 is fixedly connected to the end of the round head 26. The threaded rod 20 is driven to move by the movement trajectory of the connecting rod 15.
[0026] In this embodiment, please refer to Figure 4 and Figure 6 The upper semicircular cover 17 and the lower semicircular cover 18 are installed and fixed using fixing bolts 16 and fixing nuts 19. This allows the round head 26 on the threaded rod 20 to be installed between the upper semicircular cover 17 and the lower semicircular cover 18, and also makes it easy to disassemble for easy replacement later.
[0027] In this embodiment, please refer to Figure 4 The bottom of the threaded rod 20 has a relatively smooth surface, on which a protrusion 23 is fixedly installed. Using the function of the protrusion 23, the stirring blade 22 can be detachably installed on the threaded rod 20. In this way, when the threaded rod 20 rotates, it will also rotate the stirring blade 22, thereby playing a stirring role.
[0028] In this embodiment, please refer to Figure 4 and Figure 5 The first clasp 24 and the second clasp 25 are detachably installed on the threaded rod 20. The two are located at both ends of the stirring blade 22, which can effectively fix the stirring blade 22 and also facilitate the disassembly of the stirring blade 22. Different types of stirring blades 22 can be replaced to make the stirring more thorough and uniform.
[0029] In this embodiment, please refer to Figure 4A Z-shaped fixing plate 12 is fixedly installed at the bottom of the motor 11, and a threaded collar 21 is fixedly installed at the end of the Z-shaped fixing plate 12. The threaded rod 20 is threadedly connected to the threaded collar 21. Under the action of the internal thread, the threaded rod 20 can move up and down and rotate under the drive of the motor 11 with the disc 13, the small cylinder 14 and the connecting rod 15. This can drive the stirring fan blade 22 to rotate and move up and down at the same time, which can effectively stir the coating inside the stirring chamber 1 and make it more uniform.
[0030] In this embodiment, please refer to Figure 1 An annular pipe 5 is fixedly installed on the inner side surface of the mixing chamber 1. The annular pipe 5 is fixedly connected to the connecting pipe 7 and the mounting head 8. The mounting head 8 is connected to the external water pipe. After clean water enters the annular pipe 5, it will flow out from the nozzle 6 at the bottom of the annular pipe 5, which can clean the inside of the mixing chamber 1 and ensure that the inner wall remains clean after the coating is mixed, making it convenient for reuse.
[0031] In this embodiment, please refer to Figure 1 and Figure 2 A base bracket 2 is fixedly installed at the bottom of the mixing chamber 1 to support the entire mixing device. A discharge port 9 is provided at the bottom of the mixing chamber 1, and the mixed coating can flow out from the discharge port 9 by simply opening the valve switch 10 fixedly installed at the discharge port 9.
[0032] The specific usage and function of this embodiment are as follows:
[0033] The electric motor 11 drives the disc 13 to rotate, which in turn drives the small cylinder 14 to rotate, thereby creating a motion trajectory for the connecting rod 15. The upper semi-circular cover 17 and the lower semi-circular cover 18 cover the round head 26, which can rotate at a large angle. The motion trajectory created by the connecting rod 15 drives the threaded rod 20 to move. Since the threaded rod 20 is threadedly connected to the threaded collar 21, it can move up and down and rotate under the action of the electric motor 11. This drives the stirring fan blade 22 to rotate and move up and down, effectively stirring the coating inside the mixing chamber 1 and making it more uniform.
[0034] An annular pipe 5 is fixedly installed on the inner side surface of the mixing chamber 1. The annular pipe 5 is connected to the connecting pipe 7 and the mounting head 8. The mounting head 8 is connected to the external water pipe. After clean water enters the annular pipe 5, it will flow out from the nozzle 6 at the bottom of the annular pipe 5, which can clean the inside of the mixing chamber 1, ensuring that the inner wall remains clean after the paint is mixed, making it easy to reuse and preventing different paints from mixing.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
