Description

Technical Field

[0001] This utility model relates to the field of powder pulverization, specifically to an airflow pulverizer. Background Technology

[0002] Toner is a core consumable for printers. The toner production process requires pulverization. Traditional powder pulverizers produce toner with irregular shapes such as rhombuses, sharp corners, strips, and uneven surfaces. Such toner affects print quality and printing costs. Therefore, it is necessary to spherize the toner during the pulverization process to reduce the generation of irregularly shaped toner. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides an airflow pulverizer, comprising: a discharge nozzle with a transverse inner channel running through it; a feeder connected to the top of the middle part of the discharge nozzle and having its bottom output end connected to the transverse inner channel; a compressed air nozzle located at the right end of the transverse inner channel and outputting compressed air to the transverse inner channel; a flow divider located on the left side of the discharge nozzle and directly opposite the left end of the transverse inner channel; and a shaping cylinder fitted around the flow divider and extending in the left-right direction.

[0004] Preferably, the diverter block includes: a cylindrical column placed horizontally in the left-right direction, and a conical cone head located at the right end of the column with its tip pointing to the right.

[0005] Preferably, the cone head is coaxial with the transverse inner channel of the discharge nozzle.

[0006] Preferably, the column is coaxial with the transverse inner channel of the discharge nozzle.

[0007] Preferably, the shaping cylinder is cylindrical.

[0008] Preferably, the shaping cylinder and the transverse inner channel of the discharge nozzle are coaxial.

[0009] Preferably, the discharge nozzle is provided with a vertical inner channel that connects the bottom output end of the feeder with the middle of the transverse inner channel.

[0010] The advantages and beneficial effects of this utility model are as follows: It provides an airflow pulverizer suitable for producing toner, which can make the toner spherical during the toner pulverization process, reduce the generation of irregularly shaped toner, and thus achieve the effect of toner shaping during the pulverization process, making the toner more rounded and uniform in size, thereby improving the printing quality of the toner.

[0011] The feeder supplies coarse toner powder to the discharge nozzle. The coarse toner powder enters the transverse inner channel from the vertical inner channel of the discharge nozzle. The compressed air nozzle outputs compressed air (high-pressure airflow) to the transverse inner channel of the discharge nozzle. The compressed air blows the material in the transverse inner channel at high speed onto the diverter block (cone), forming an initial impact. The material impacts the diverter block (cone), causing fission and achieving the crushing of large-diameter materials. The powder generated by the impact fission is driven by inertia and high-pressure airflow, and then obliquely impacts the inner wall of the shaping cylinder around the diverter block (cone), forming a secondary impact. This achieves the effect of toner shaping, making the toner more rounded and uniform in size, thereby improving the printing quality of the toner. Attached Figure Description

[0013] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0014] The specific technical solution of this utility model is as follows:

[0015] like Figure 1 As shown, this utility model provides an airflow pulverizer, including: a discharge nozzle 1 with a transverse inner channel 11 running through it; a feeder 2 connected to the top of the middle part of the discharge nozzle 1 and whose bottom output end is connected to the transverse inner channel 11; a compressed air nozzle 3 located at the right end of the transverse inner channel 11 and outputting compressed air to the transverse inner channel 11; a diverter block 4 located on the left side of the discharge nozzle 1 and directly opposite the left end of the transverse inner channel 11; and a cylindrical shaping cylinder 5 fitted around the diverter block 4 and extending in the left and right directions.

[0016] The discharge nozzle 1 is provided with a vertical inner channel 12 that connects the bottom output end of the feeder 2 with the middle of the transverse inner channel 11;

[0017] The diversion block 4 includes: a cylindrical column 41 that is placed horizontally in the left-right direction, and a conical cone 42 located at the right end of the column 41 with its tip pointing to the right.

[0018] The column 41, cone 42, and shaping cylinder 5 are all coaxial with the transverse inner channel 11 of the discharge nozzle 1.

[0019] The working principle of this airflow pulverizer includes:

[0020] The feeder 2 supplies coarse toner powder to the discharge nozzle 1. The coarse toner powder enters the transverse inner channel 11 through the vertical inner channel 12 of the discharge nozzle 1. The compressed air nozzle 3 outputs compressed air (high-pressure airflow) to the transverse inner channel 11 of the discharge nozzle 1. The compressed air blows the material in the transverse inner channel 11 at high speed onto the diverting block 4 (cone 42) to form an initial impact. The material impacts the diverting block 4 (cone 42) and undergoes fission, thereby crushing the large-diameter material. The powder generated by the impact fission is driven by inertia and high-pressure airflow, and then obliquely impacts the inner wall of the shaping cylinder 5 around the diverting block 4 (cone 42) to form a secondary impact, thereby achieving the effect of toner shaping, making the toner more rounded and uniform in size, and thus improving the printing quality of the toner.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
