Description

Technical Field

[0001] This utility model relates to the field of mixing technology, and more specifically, to a multi-stage mixing device for metal powder coatings. Background Technology

[0002] Metal powder and base powder have different densities, resulting in inconsistent powder application rates during electrostatic spraying, leading to uneven metal content in the coating film. Recycled powder and new powder have significant performance differences. Ordinary mixing equipment is prone to causing metal powder accumulation, resulting in color differences or coating defects, and it is difficult to ensure consistency between batches. Therefore, a multi-stage mixing device for metal powder coatings is needed to achieve multi-stage mixing operations.

[0003] In the multi-stage mixing process of metal powder coatings, a stirring shaft is required to achieve multi-stage mixing and rotation of the metal powder coating. However, when the shaft is in motion, it is difficult to periodically squeeze and adhere to the outer wall of the shaft. This makes it difficult for the lubricating oil to adhere to and lubricate the outer wall of the shaft, resulting in poor lubrication coverage. Therefore, a multi-stage mixing device for metal powder coatings is needed. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a multi-stage mixing device for metal powder coatings, comprising a mixing tank, a stirring shaft rotatably mounted on the inner wall of the mixing tank, a drive shaft coaxially fixedly connected to one end of the stirring shaft, and a lubrication assembly installed at one end of the mixing tank, the lubrication assembly comprising: The lower discharge hopper is fixedly connected to one end of the mixing tank and located above the stirring shaft. A support bar is fixedly connected to one side of the outer wall of the lower discharge hopper. A positioning post is fixedly located on the upper surface of the support bar, and a sleeve is inserted into the outer wall of the positioning post for positioning. An arc-shaped strip is fixedly located at the bottom end of the sleeve, and an arc-shaped brush for drawing in lubricating oil is fixedly installed on the inner wall of the arc-shaped strip.

[0005] In a preferred embodiment, the upper surface of the positioning post is rounded, and the sleeve and the support are in contact.

[0006] In a preferred embodiment, the vertical cross-sectional shape of both the arc-shaped strip and the arc-shaped brush is arc-shaped, and the arc-shaped brush is made of cotton material.

[0007] In a preferred embodiment, a motor is mounted on one end of the drive shaft, and the motor is used to drive the drive shaft to rotate.

[0008] In a preferred embodiment, a bearing sleeve is rotatably mounted on the outer wall of the drive shaft, and the bearing sleeve is fixedly connected to the mixing tank. A support frame is mounted on the lower surface of the motor, and the support frame is used to fix and support the motor. The mixing tank is fixedly connected to the support frame.

[0009] In a preferred embodiment, a valve body is installed at the bottom of the outer wall of the mixing tank, the valve body being used to discharge the mixed metal powder coating.

[0010] In a preferred embodiment, the bottom end of the lower hopper is fixedly connected to a hopper body, and the bottom end of the hopper body is threadedly connected to a manual valve.

[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model employs a lubrication assembly. When the hand grips the sleeve and lifts it, the arc-shaped brush is precisely moved to the bottom of the manual valve. Lubricating oil drips and is absorbed by the arc-shaped brush, which then closely adheres to the connection between the drive shaft and the bearing sleeve. The shape of the arc-shaped brush is perfectly matched to the structure of the connection, fully covering the outer wall of the drive shaft. This allows the lubricating oil to penetrate evenly into every tiny gap on the contact surface. This close-fitting lubrication treatment avoids the problem of uneven lubricating oil distribution, ensuring that the friction parts of the drive shaft and bearing sleeve are always covered with lubricating oil during relative movement, forming a stable oil film protective layer. This effectively reduces wear, extends the service life of the equipment, and provides reliable protection for later maintenance.

[0012] 2. This utility model achieves comprehensive lubrication treatment at the connection between the drive shaft and the bearing sleeve by moving the arc-shaped brush and adsorbing the lubricating oil. During the upward movement of the arc-shaped brush, it can cover the entire circumference area of ​​the connection without missing any corner, significantly improving the lubrication treatment coverage effect. In later maintenance, this operation can be quickly repeated to replenish the lubricating oil in time, greatly reducing the difficulty and time cost of maintenance and improving work efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 - Figure 4 The diagram shows a multi-stage mixing device for metal powder coatings. The device is equipped with a lubrication component. The lubrication component ensures that the friction parts between the drive shaft 3 and the bearing sleeve 11 are always covered with lubricating oil during relative movement, forming a stable oil film protective layer. This effectively reduces wear, extends the service life of the equipment, and provides reliable protection for later maintenance. The specific structure of the lubrication component is as follows.

[0020] In this embodiment, as Figure 1 - Figure 3 As shown, a stirring shaft 2 is rotatably mounted on the inner wall of the mixing tank 1. A drive shaft 3 is coaxially fixedly connected to one end of the stirring shaft 2. A lubrication assembly is installed at one end of the mixing tank 1. The lubrication assembly includes: a lower discharge hopper 4, fixedly connected to one end of the mixing tank 1 and located above the stirring shaft 2, with a support bar 5 fixedly connected to one side of the outer wall of the lower discharge hopper 4; a positioning post 6, fixedly located on the upper surface of the support bar 5, with a sleeve 7 inserted into the outer wall of the positioning post 6; and an arc-shaped strip 8, fixedly located at the bottom end of the sleeve 7, with an arc-shaped brush 9 for sucking up lubricating oil fixedly installed on the inner wall of the arc-shaped strip 8. The upper surface of the positioning post 6 is rounded, and the sleeve 7 and the support bar 5 are in contact. The vertical cross-sectional shape of the arc-shaped strip 8 and the arc-shaped brush 9 are both arc-shaped, and the arc-shaped brush 9 is made of cotton material.

[0021] In this embodiment, as Figure 1 As shown, a motor 10 is installed at one end of the drive shaft 3. The motor 10 is used to drive the drive shaft 3 to rotate, so that the motor 10 can drive the drive shaft 3 to rotate and realize the stable transmission of the drive shaft 3.

[0022] In this embodiment, as Figure 1As shown, a bearing sleeve 11 is rotatably mounted on the outer wall of the drive shaft 3, and the bearing sleeve 11 is fixedly connected to the mixing tank 1; a support frame 12 is mounted on the lower surface of the motor 10, and the support frame 12 is used to fix and support the motor 10. The mixing tank 1 is fixedly connected to the support frame 12 so that the support frame 12 can support the motor 10, increase the stability of the motor 10, and ensure that the drive shaft 3 can be stably driven to rotate inside the bearing sleeve 11, thus ensuring that the drive shaft 3 drives more stably.

[0023] In use, the multi-stage mixing device for metal powder coatings uses a support frame 12 to support the motor 10, increasing its stability. After opening the top cover of the mixing tank 1, the metal powder coating is placed inside the mixing tank 1. The motor 10 drives the drive shaft 3 to rotate, which rotates stably within the bearing sleeve 11. The drive shaft 3 also drives the stirring shaft 2 to rotate inside the mixing tank 1, performing multi-stage mixing of the metal powder coating inside the mixing tank 1. The valve 13 is then closed. Other different metal powder coatings are then added to the mixing tank 1 in batches for multi-stage mixing.

[0024] Open the top cover of the lower hopper 4 to pour lubricating oil into the lower hopper 4 for storage. When needed, hold the sleeve 7 on the outer wall and pull it upwards. The sleeve 7 will slide upwards along the outer wall of the positioning post 6, and the lower hopper 4 will support the support bar 5, which in turn supports the positioning post 6. This separates the sleeve 7 from the support bar 5. The sleeve 7 drives the arc-shaped bar 8 upwards, and the arc-shaped bar 8 drives the arc-shaped brush 9 upwards. The arc-shaped brush 9 then moves to the bottom of the manual valve 15. Manually open the manual valve 15, and the lubricating oil inside the lower hopper 4 will flow down the hopper body 14 through the manual valve 15. The lubricating oil drips onto the outer wall of the arc-shaped brush 9, absorbing a large amount of lubricating oil. The arc-shaped brush 9 will then apply the lubricating oil to the connection between the drive shaft 3 and the bearing sleeve 11, thus fully lubricating the connection between the drive shaft 3 and the bearing sleeve 11, making future maintenance easier.

[0025] In this embodiment, as Figure 1 As shown, a valve body 13 is installed at the bottom of the outer wall of the mixing tank 1. The valve body 13 is used to discharge the mixed metal powder coating. This allows the valve body 13 to be opened after the mixing inside the mixing tank 1 is complete, so that the mixed metal powder coating inside the mixing tank 1 can be discharged.

[0026] In this embodiment, as Figure 4 As shown, the bottom end of the lower discharge hopper 4 is fixedly connected to the hopper body 14, and the bottom end of the hopper body 14 is threadedly connected to the manual valve 15 so that the manual valve 15 can be opened. In this way, the lubricating oil enters the hopper body 14 along the inside of the mixing tank 1, and is guided by the hopper body 14 to the manual valve 15. After the manual valve 15 is opened, the discharge is achieved quickly.

[0027] The motor 10 is connected in series with the switch, which is a conventional circuit and is known to those skilled in the art. The model parameters of each electrical appliance are not specifically limited and conventional equipment can be used. Electrical control components not mentioned in this technical solution are not shown in the figure because they are existing technologies and will not be described here.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
