The air jet assembly comprises an air nozzle 21 arranged in the crushing cylinder 1 and an air supply pipe 22 for supplying air to the air nozzle. The crushing assembly is used to collide with the pearlescent pigment to disperse it. It is worth noting that in order to prevent the coating layer on the surface of the pearlescent pigment from being damaged due to excessively fast airflow, a low-speed airflow or intermittent inflation should be used.

[0034] The crushing assembly includes a flexible collision rod 31 arranged on the inner wall of the crushing barrel 1, and the flexible collision rod 31 can collide with the pearlescent pigment during the movement of the pearlescent pigment. Preferably, the flexible collision rod 31 is a rubber rod. In this way, when the flexible collision rod 31 collides with the pearlescent pigment agglomerates, it will not scratch the surface of the pearlescent pigment. In the present application, a flexible collision rod is arranged in the crushing barrel 1, which increases the collision efficiency of the pearlescent pigment, so that the pearlescent pigment agglomerates are broken, and the surface coating layer of the pearlescent pigment is not damaged.

[0035] A feed barrel 13 is installed at the feed port 12, and a drive shaft 14 and a spiral blade 15 are rotatably installed in the feed barrel 13. The spiral blade 15 is fixed to the side of the drive shaft 14. The drive shaft 14 is connected to a drive mechanism at one end away from the feed port 12. A feed hole 16 is provided on the feed barrel 13. In the present application, the spiral blade 15 is provided to transport the pearlescent pigment during the rotation of the drive shaft 14, so as to ensure stable transportation speed and efficiency.

[0037] The crushing assembly also includes a protrusion 32, which is arranged at the top of the inner wall of the feed barrel 13. When the spiral blade 15 passes through the protrusion 32, the protrusion 32 can drive the spiral blade 15 to vibrate. In the present application, not only is a flexible collision rod 31 provided in the crushing barrel 1 to collide with the pearlescent pigment, but a protrusion 32 is also provided in the feed barrel 13 to control the vibration of the pearlescent pigment, so that the pearlescent pigment is loose. Specifically, the spiral blade 15 is an elastic structure, and when it rotates through the protrusion 32, the protrusion 32 can drive the spiral blade 15 to deform and then reset. In this process, the spiral blade 15 vibrates, and drives the pearlescent pigment in the transportation process to vibrate, and the pearlescent pigment agglomerates collide with each other and break.

[0038] In this embodiment, a second method for controlling the vibration of the spiral blades 15 is also provided.

[0039] In the present application, the reciprocating drive mechanism is used to drive the drive shaft 14 to slide back and forth. The reciprocating drive mechanism includes a drive disk 44, a drive column 45, and a second motor 47. The second motor 47 is used to drive the drive disk 44 to rotate. There are multiple drive columns 45, which are respectively arranged on the drive disk 44. A spring 46 is arranged between the transmission disk 43 and the output shaft 41. When the drive disk 44 rotates, the drive column 45 can drive the transmission disk 43 to slide axially along the output shaft 41. The spring 46 is used to drive the transmission disk 43 to reset. In the present application, if Figure 4 The driving disc 44 can drive the driving column 45 to rotate during clockwise rotation, thereby driving the transmission disc 43 to slide to the left. At this time, the spring 46 is a tension spring, which is used to drive the transmission disc 43 to reset to the right when it is separated from the driving column 45; of course, the driving disc 44 can also rotate counterclockwise to drive the transmission disc 43 to slide to the right. At this time, the spring 46 is a compression spring, which is used to drive the transmission disc 43 to reset to the left when it is separated from the driving column 45. In the present application, the driving disc 44 and the driving column 45 are set as the driving mechanism. In actual use, a piston, a telescopic rod and other devices can also be set to drive the driving shaft 14.

[0040] In the present application, a grading wheel 18 is provided at the top of the crushing cylinder 1, and the output end of the grading wheel 18 is connected to the discharge port 11. Pearlescent pigments whose particle size reaches the output range after crushing can be discharged from the discharge port 11 after passing through the grading wheel 18, while pearlescent pigments whose particle size is larger and does not reach the output range continue to be crushed in the crushing cylinder 1. The gap on the grading wheel 18 should be set to match the size of the pearlescent pigment to be output, and in actual use, a size slightly larger than the pearlescent pigment to be output should be selected to prevent the pearlescent pigment from colliding and breaking when entering the grading wheel 18.

[0041] A discharge channel 19 is provided at the bottom of the crushing drum 1 to regularly clean the pearlescent pigments with large particle sizes that cannot be discharged. A valve is usually provided for control during use.
