[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, a discharging mechanism for powder coating production includes a lower shell 1, an upper shell 2, a pre-discharging chamber 3, a servo electric cylinder 6, a blocking groove 7, a viscosity detection probe 11, an inclined discharging channel 4 and a blocking plate 8. A detection chamber 15 and a circular chamber 9 are respectively opened near both ends in the upper shell 2, and an annular limiting protrusion 10 is provided on the inner wall of the circular cavity 9 near the detection chamber 15. A sealing ring 12 is provided on the periphery of the viscosity detection probe 11, and the sealing ring 12 is located on the outside of the annular limiting protrusion 10. The end of the viscosity detection probe 11 is located in the detection chamber 15. A PLC controller 16 is installed on the top of the upper shell 2 by screws, and a vertical plate 5 is welded near the center of the bottom of the inclined discharging channel 4. A servo electric cylinder 6 is installed on one end of the vertical plate 5 by bolts. The power output end of the servo electric cylinder 6 is connected to the blocking plate 8, and the blocking plate 8 is located in the blocking groove 7.

[0020] Among them, a through groove is penetrated through the upper shell 2 near one end of the circular cavity 9, and the end of the viscosity detection probe 11 passes through the through groove. Adjustment studs 13 are provided through threaded holes at the top of the upper shell 2 near the upper and lower ends of the through groove, and the ends of the adjustment studs 13 are located on the outside of the sealing ring 12.

[0021] In this embodiment, Figure 1 As shown, the sealing ring 12 is conveniently pressed against the outside of the annular limiting protrusion 10 by adjusting the stud 13, so that the sealing effect between the viscosity detection probe 11 and the inner wall of the circular cavity 9 is greatly improved.

[0022] Wherein, a knob 14 is arranged on the periphery of the end of the adjusting stud 13 .

[0023] In this embodiment, Figure 1 As shown, by applying external force to the knob 14, the adjusting stud 13 can be driven to rotate.

[0024] Wherein, a connecting block 17 is arranged at the periphery of the end of the lower shell 1 and the upper shell 2, and a connecting bolt 18 is arranged at one end of the connecting block 17 through a reserved hole.

[0025] In this embodiment, Figure 1 As shown, the mechanism is conveniently fixed to one side of the bottom end of the mixing tank by connecting bolts 18.

[0026] Wherein, a pre-discharge cavity 3 and an inclined discharge channel 4 are respectively opened at both ends of the lower shell 1.

[0027] In this embodiment, Figure 1 and Figure 3 As shown, by tilting the discharge channel 4, better discharge can be performed after the blocking plate 8 is opened.

[0028] The blocking plate 8 is specifically made of stainless steel.

[0029] In this embodiment, Figure 1 and Figure 3 As shown, the blocking plate 8 made of stainless steel has good strength and corrosion resistance, and can effectively improve reliability during use.

[0030] It should be noted that the utility model is a discharge mechanism for powder coating production. When working, a discharge port is set on one side of the bottom end of the mixing tank for producing powder coating. The mechanism is conveniently fixed to one side of the discharge port by connecting bolts 18. The PLC controller 16, the viscosity detection probe 11 and the servo electric cylinder 6 are all connected to an external power supply. By tightening the adjusting stud 13, the sealing ring 12 is conveniently pressed against the outside of the annular limit convex block 10, thereby improving the sealing effect between the viscosity detection probe 11 and the inner wall of the circular cavity 9. The viscosity detection probe 11 is convenient for detecting the viscosity of the material entering the detection chamber. The viscosity of the powder coating in the measuring chamber 15 is measured, and the signal is transmitted to the PLC controller 16. After analyzing the viscosity signal, the PLC controller 16 controls the servo electric cylinder 6 to open when the viscosity reaches a certain value, thereby driving the blocking plate 8 to descend from the blocking groove 7, so that the powder coating in the mixing tank enters the inclined discharge channel 4 through the pre-discharge chamber 3, and is then discharged through the inclined discharge channel 4. The discharge mechanism has a structure that can conveniently detect the viscosity of the powder coating and discharge according to the detected concentration. There is no need for manual discharge by personnel, and the operation is convenient and quick.
