Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 4, a medicine powder dispersing device includes a first-order powdering box and a second-order powdering box; two first-order powdering boxes 2 are respectively assembled in the second-order powdering box 1 in tandem. On the left and right sides, the top of the first-order powder box 2 is provided with a feeding port 2-1, the first-order powder box 2 is equipped with a first-order powder mechanism 4, and the first-order powder box 2 passes through the material powder change box 2-2 It is communicated with the second-order powdering box 1. The second-order powdering box 1 has a built-in second-order powdering mechanism 7. The bottom of the second-order powdering box 1 is equipped with a discharge box 3. 1. Wherein, the powder block ready to be broken is put into the first-stage powder box 2 from the feeding port 2-1, and the first-order powder mechanism 4 built in the first-order powder box 2 performs preliminary breaking processing on the powder block. After the first-stage treatment is completed, the preliminarily processed medicinal powder enters the second-stage powdering box 1 through the material powder changing port 2-2. At this time, the medicinal powder is then disintegrated by the second-stage powdering mechanism 7 built in the second-stage powdering box 1. . After finishing the refinement of the medicinal powder, the staff can take out the medicinal powder from the discharge port 3-1 on the discharge box 3 .

As shown in FIG. 2 , the first-order powder-beating mechanism 4 is composed of two rotary powder-beaters 4-5. The two rotary powder-beaters 4-5 are installed on the same horizontal line, and the rotation directions of the two rotary powder-beaters 4-5 are opposite to each other. on the contrary. Among them, in order to break up the powder block in one stage more efficiently, two horizontally installed rotary powder grinders 4-5 are used to perform a cross-type powder breaking process in a relatively rotating manner. In this way, the falling large pieces of powder can be broken up in a cross manner, which can reduce the omission rate of breaking up large pieces of powder.

As shown in FIG. 3 , the rotary pulverizer 4-5 includes a dust-proof shaft sleeve 4-1, the dust-proof shaft sleeve 4-1 is controlled and connected to the servo motor 5 through the rotating shaft 6, and the dust-proof shaft sleeve 4-1 1. A number of powder-beating arms 4-2 are installed on both sides, the middle of the powder-beating arm 4-2 is open with a square hole 4-5, and the end of the powder-beating arm 4-2 is equipped with a pushing blade 4-3. Wherein, in order to break up the large pieces of medicinal powder in the first stage, the powder-beating arm 4-2 on the rotary pulverizer 4-5 can crush the large pieces of powder through a cross movement to achieve the effect of breaking up. In order to reduce the movement resistance of the powder-beating arm 4-2 in the powder, a square hole 4-5 is opened in the middle of the powder-beating arm 4-2, so that the contact area of the powder of the powder-beating arm 4-2 can be effectively reduced. Reduced movement resistance. In order to increase the convenience of transportation, a pushing blade 4-3 is installed at the end of the powdering arm 4-2.

As shown in FIG. 4 , the second-stage powder-beating mechanism 7 includes three rotating frames 7-1, and a number of powder-beating blades 7-2 are mounted on the longitudinal arms of the rotating frame 7-1. The size is gradually decreased, and the three rotating frames 7-1 are installed on the rotating shaft 6 in turn according to the size. Motor 5 control connection. Among them, in the refining process of the second stage, the present invention sets a number of powder-beating blades 7-2 on the rotating frame 7-1, so that when the three rotating frames 7-1 rotate in an intersecting manner, the powder blades at both ends can pass through the powder blades 7-1. 7-2 Do finer refinement of the powder.

To sum up, the present invention can use a two-stage powdering device to refine the medicinal powder. The first-stage powdering device can effectively preliminary refine the block powder, and the second-stage powdering device can further refine the powder through the powdering knife.

Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that these are only examples, and various changes or modifications can be made to the embodiments without departing from the principle and essence of the present invention. The scope of protection is limited only by the appended claims.
