DETAILED DESCRIPTION

[0018] In the following, the present application will be further described in conjunction with the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0019] As Figs. 1-3As shown, the ink micro-wax airflow crushing device comprises a base 1 and a crushing chamber arranged on the top of the base 1, the crushing chamber comprises a crushing bin 2, a grading bin 3 and a storage tank 5, the grading bin 3 is arranged on the upper part of the crushing bin 2, a gas conveying ring 4 is arranged on the outer wall of the crushing bin 2, the gas conveying ring 4 is a hollow structure, a plurality of gas conveying pipes 40 are arranged on the gas conveying ring 4, two material spraying pipes 21 and at least two pairs of air nozzles 22 are further arranged on the outer wall of the crushing bin 2, one end of the material spraying pipe 21 and one end of the air nozzle 22 are both located on the inner side of the crushing bin 2, the other end of the material spraying pipe 21 and the other end of the air nozzle 22 are both located on the outer side of the crushing bin 2, and the other end of the material spraying pipe 21 and the other end of the air nozzle 22 are both communicated with the gas conveying ring 4 through the gas conveying pipe 40; the air nozzle 22 is used for spraying airflow to the inside of the crushing bin 2, and the material spraying pipe 21 is used for spraying material flow to the inside of the crushing bin 2. The storage tank 5 is provided with a material suction pipe 51, two discharge pipes 52 are communicated with the material suction pipe 51, the two discharge pipes 52 are respectively and one-to-one communicated with the two material spraying pipes 21, the material suction pipe 51 and the gas conveying pipe 40 on the material spraying pipe 21 are communicated through the discharge pipe 52, and the gas flows in the gas conveying pipe 40 and generates negative pressure at the communication part of the gas conveying pipe 40 and the discharge pipe 52.

[0020] When the external gas source inputs gas into the gas conveying ring 4, the gas will uniformly enter the plurality of gas conveying pipes 40. The gas conveying pipe 40 communicated with the air nozzle 22 will directly spray airflow into the crushing bin 2, and the gas conveying pipe 40 communicated with the material spraying pipe 21 will generate negative pressure at the end communicated with the discharge pipe 52 during flowing into the material spraying pipe 21, so as to suck the material in the storage tank 5 into the material spraying pipe 21, so that the gas in the air nozzle and the material are mixed and form a material flow. The two material spraying pipes 21 and the plurality of air nozzles 22 are arranged in the same plane and all point to the axis of the crushing bin 2, so that the airflow sprayed from the air nozzle 22 and the material flow sprayed from the material spraying pipe 21 will meet and collide on the axis of the crushing bin 2, so as to realize the crushing of the material by multiple airflows, and the airflow will move upward after the collision, so as to carry the crushed material into the grading bin 3 and discharge outward. Since two material spraying pipes 21 are arranged in the present application, and any pair of air nozzles 22 is symmetrically arranged on the two sides of the crushing bin 2, the plurality of air nozzles 22 are equidistantly arranged along the same circumference, the axes of the two material spraying pipes 21 are perpendicular to each other, and any material spraying pipe 21 is arranged between the two air nozzles 22, so that the material flow can move to the axis of the crushing bin 2 from different places, so as to make the airflow more reliably crush the material, and significantly improve the crushing effect of the material.

[0021] The outside of the crushing chamber is further provided with a switching mechanism 6 for switching the communication state of the two discharge pipes 52 and the suction pipe 51, the switching mechanism 6 comprising a housing 61 and a rotating block 62, one end of the suction pipe 51 being inserted into the storage tank 5 in an open state, the other end of the suction pipe 51 being inserted into the housing 61 in a closed state, and the rotating block 62 being adaptedly arranged inside the other end of the suction pipe 51; the rotating block 62 is provided with a cavity 621 in communication with the inside of the suction pipe 51, and two discharge ports 622 in communication with the cavity 621 are arranged on the outer wall of the rotating block 62, the rotating block 62 being rotatable inside the suction pipe 51, when one discharge port 622 is in communication with one discharge pipe 52, the other discharge port 622 is separated from the other discharge pipe 52. The communication position of one discharge pipe 52 with the suction pipe 51 is located on one side of the suction pipe 51, and the communication position of the other discharge pipe 52 with the suction pipe 51 is located on the other side of the suction pipe 51, the communication positions of the two discharge pipes 52 with the suction pipe 51 being arranged in a staggered manner along the axial direction of the suction pipe 51; one discharge port 622 is arranged on one side of the rotating block 62 and can be in communication with one discharge pipe 52, and the other discharge pipe 52 is arranged on the other side of the rotating block 62 and can be in communication with the other discharge pipe 52.

[0022] By rotating the rotating block 62, the positions of the two discharge ports 622 on the rotating block 62 can be adjusted, and the two discharge ports 622 are in a perpendicular state, so that when one discharge port 622 of the rotating block 62 is rotated to be in communication with one discharge pipe 52, the other discharge port 622 of the rotating block 62 cannot be in communication with the other discharge pipe 52, at this time, the material sucked into the suction pipe 51 will directly enter the cavity 621, and then enter one discharge pipe 52 through one discharge port 622, at this time, one discharge pipe 52 can deliver the material to the corresponding one of the two spray pipes 21, and the spray pipe 21 is in a spraying state, while the other discharge pipe 52 is blocked by the rotating block 62. After one spray pipe 21 sprays the material flow for a period of time, the rotating block 62 is rotated to disconnect one discharge port 622 of the rotating block 62 from one discharge pipe 52, and to make the other discharge port 622 of the rotating block 62 in communication with the other discharge pipe 52, at this time, the other spray pipe 21 in communication with the other discharge pipe 52 is in a spraying state. By rotating the rotating block 62, the two spray pipes 21 are alternately in a spraying state, so that the two material flows can impact the airflow from different directions, significantly improving the crushing effect on the material.

[0023] The outer wall of the rotating block 62 and the end of the suction pipe 51 form a closed cavity 510, one side of the rotating block 62 located in the closed cavity 510 is provided with a rotating shaft 623, the housing 61 is also provided with a motor 63, the output shaft of the motor 63 extends into the closed cavity 510 and is connected between the rotating shaft 623 through a transmission gear set 624, the motor 63 is used to drive the rotating shaft 623 to rotate. The rotating shaft 623 and the transmission gear set 624 are arranged in the closed cavity 510 and are not affected by the material, which ensures that the rotating block 62 can reliably rotate along its own axis under the driving of the motor 63 and the transmission of the transmission gear set 624, thereby realizing the switching of the two discharge pipes 52, having high automation degree, improving the control precision of the rotating amount of the rotating block 62, and further ensuring that the two spray pipes 21 can be in the alternating spraying state.

[0024] The above-described embodiments are merely preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and replacements made by those skilled in the art based on the present application shall fall within the scope of protection of the present application.
