[0026] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, a powder coating raw material mixer according to one embodiment of the present invention includes a mixing tank 1 and a mixing mechanism; a mixing chamber 111 is formed inside the mixing tank 1, and a discharge pipe 2 communicating with the mixing chamber 111 is provided at the bottom of the mixing tank 1. A metering valve 3 is installed on the discharge pipe 2, and a deflection structure for controlling the flow state of the discharge pipe 2 is provided inside the metering valve 3; the mixing mechanism includes a mixing element 4 and a drive assembly 5 installed on the mixing tank 1. The output end of the drive assembly 5 extends into the mixing chamber 111 and is connected to the mixing element 4 in a transmission manner. A plurality of mixing blades 42 are provided at intervals on the mixing element 4.

[0028] The aforementioned powder coating raw material mixer, by being equipped with a mixing chamber 111, facilitates powder collection and mixing operations, providing a sealed space for powder processing; by being equipped with a deflection structure, the deflection structure can control the opening and closing degree of the metering valve 3, thereby controlling the amount of powder discharged from the discharge pipe 2, solving the problem of inaccurate control of the amount of powder discharged; by being equipped with a drive component 5, the drive component 5 controls the rotation of the mixing component 4, thereby driving the mixing blade 42 to perform mixing operations on the powder; by being equipped with multiple mixing blades 42, the degree of powder mixing is improved, which is conducive to the uniform mixing of powder.

[0029] like Figure 1 and Figure 2As shown, in one embodiment, the mixing tank 1 includes an upper tank body 11 and a lower tank body 12 connected vertically. A mixing chamber 111 is formed inside the upper tank body 11, and an installation chamber 121 is formed inside the lower tank body 12. The mixing chamber 111 and the installation chamber 121 are separated by a partition 13. A discharge port is provided at the center of the partition 13. One end of the discharge pipe 2 is inserted into the discharge port, and the other end of the discharge pipe 2 passes through the installation chamber 121 and extends to the outside of the mixing tank 1. The installation chamber 121 provides space for the installation of the discharge pipe 2.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, a feed inlet is provided on the inner wall of the upper tank 11, and a feed pipe 112 is inserted into the feed inlet to facilitate the feeding of powder.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, the powder coating raw material mixer further includes a drying mechanism. The drying mechanism includes a temperature control device 6, an air inlet pipe 7, and an air outlet pipe 8. The air inlet pipe 7 is connected to the air inlet end of the temperature control device 6, and a pressure gauge 71 is installed on the air inlet pipe 7. The air outlet end of the temperature control device 6 is connected to one end of the air outlet pipe 8. An air outlet is provided on the partition 13, and the other end of the air outlet pipe 8 is inserted into the air outlet and extends into the mixing chamber 111. The height of the air outlet pipe 8 protruding from the partition 13 is higher than the height of the discharge port. By providing the temperature control device 6, the temperature inside the mixing chamber 111 is controlled, maintaining a dry and constant temperature environment within the mixing chamber 111. This allows the powder to be mixed more evenly during the mixing process and is not affected by a humid environment.

[0032] like Figure 2 and Figure 3 As shown, in one embodiment, the partition 13 is composed of multiple interconnected anti-corrosion plates 131, and the discharge port is provided with a sealing cap 132 by a threaded cover; thus, the anti-corrosion plates 131 are convenient for workers to clean, and also convenient for removing the cleaning agent used during cleaning, reducing corrosion; the sealing cap 132 is also convenient for workers to temporarily close the discharge port, which is beneficial for the cleaning operation.

[0033] Preferably, the temperature control device 6 is a fan. Fans are existing technology and will not be described in detail.

[0034] like Figure 4As shown, in one embodiment, the deflection structure includes a deflection shaft 31, a flow-blocking fan 32, and a control handle 33. The deflection shaft 31 is disposed through the metering valve 3 and can rotate relative to the metering valve 3. The flow-blocking fan 32 is detachably fixed to the deflection shaft 31 and is disposed inside the metering valve 3. The radius of the flow-blocking fan 32 is adapted to the inner diameter of the metering valve 3. The operator can adjust the rotation of the deflection shaft 31 by operating the control handle 33, thereby adjusting the opening and closing degree of the flow-blocking fan 32, and thus controlling the flow rate of powder in the discharge pipe 2, thereby controlling the final amount of powder discharged.

[0035] like Figure 4 As shown, in one embodiment, the deflection structure further includes an angle display 34, which is mounted on the control handle 33 and used to display the deflection angle of the deflection shaft 31 relative to its initial position. The operator can control different powder feeding rates within the same time period based on the deflection angle of the deflection shaft 31.

[0036] like Figure 2 and Figure 3 As shown, in one embodiment, multiple interconnected anti-corrosion wall blocks 113 are laid on the inner wall of the upper tank 11. Each anti-corrosion wall block 113 has a sealing strip fixedly connected to both ends, and the sealing strips at both ends of the anti-corrosion wall block 113 are matched and staggered. Thus, by providing sealing strips, the sealing performance of the anti-corrosion wall blocks 113 is increased, further enhancing the protection of the inner wall of the upper tank 11. The presence of anti-corrosion wall blocks 113 also facilitates cleaning or replacement of the inner wall of the upper tank 11 by workers, and makes it easier to remove cleaning agents used during cleaning, reducing corrosion.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment, the drive assembly 5 includes a transmission rod 51 and a drive motor 52 mounted on the top of the upper tank 11. The output end of the drive motor 52 extends into the stirring chamber 111 and is connected to one end of the transmission rod 51.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
