Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The utility model specifically provides the following technical solutions:

A decoction piece dispensing device, as shown in FIG1 , comprises a silo 1, a primary feeding mechanism 2, a crushing mechanism 3, a secondary feeding mechanism 4 and a weighing hopper 5 which are arranged in sequence according to the decoction piece processing sequence;

The silo 1 is used to store the large-grained medicinal pieces to be crushed and to supply the large-grained medicinal pieces to the primary feeding mechanism 2;

The crushing mechanism 3 can crush the large-grained medicinal pieces delivered by the primary feeding mechanism 2, and add the crushed small-grained medicinal pieces to the secondary feeding mechanism 4;

The secondary feeding mechanism 4 can convey the small-particle medicinal pieces to the weighing hopper 5 according to the received adjustment information, and adjust the conveying flow rate or stop conveying according to the weighing signal fed back by the weighing hopper 5.

On the whole, the medicinal slices dispensing device can be divided into a crushing part consisting of a silo 1, a primary feeding mechanism 2 and a crushing mechanism 3, and a dispensing part consisting of a secondary feeding mechanism 4 and a weighing hopper 5.

When the dispensing part is short of material, the primary feeding mechanism 2 feeds material to the crushing mechanism 3, and the crushing mechanism 3 crushes the large-grained pieces into small-grained pieces, and the small-grained pieces fall downward from the crushing mechanism 3 to the secondary feeding mechanism 4 for standby use. When dispensing, the small-grained pieces are directly dispensed to avoid the occurrence of drug jam. At the same time, the particle weight of the small-grained pieces is smaller, and the minimum weight of the pieces fed by the secondary feeding mechanism 4 during dispensing is also smaller, which can improve the dispensing accuracy.

During the adjustment, the secondary feeding mechanism 4 delivers an appropriate amount of small-grained slices to the weighing hopper 5 according to the received adjustment information, and the weighing hopper 5 weighs in real time and feeds back the weighing information to the secondary feeding mechanism 4. The secondary feeding mechanism 4 adjusts the feeding speed according to the received weighing information compared with the adjustment weight required in the adjustment information.

If the weight of the medicinal pieces in the weighing hopper 5 is close to the required weight in the adjustment information, the feeding speed is reduced and the feeding is refined to avoid overfeeding. At the same time, sufficient feedback and adjustment time is given to the weighing hopper 5 and the secondary feeding mechanism 4 so that the weight of the small-particle medicinal pieces in the final weighing hopper 5 is consistent with the required weight in the adjustment information, thereby further improving the adjustment accuracy.

Furthermore, in order to facilitate the upper-level mechanism to drop the processed medicinal pieces into the lower-level mechanism, the silo 1, the primary feeding mechanism 2, the crushing mechanism 3, the secondary feeding mechanism 4 and the weighing hopper 5 are arranged in order from high to low, that is, the discharge port of the upper-level mechanism is located above the feed port of the lower-level mechanism.

Furthermore, as shown in Figure 2, the silo 1 includes a silo body 101 and a silo door 102. The lower end of the silo body 101 is open as a discharge port and is located above the primary feeding mechanism 2. The silo door 102 is installed on the side of the silo body 101, and the silo door 102 can be opened to replenish large-grain medicinal pieces into the silo body 101.

Furthermore, as shown in FIG. 3 , the primary feeding mechanism 2 includes a primary vibrator 201 and a primary vibration plate 202 ; the primary vibrator 201 is used to drive the primary vibration plate 202 mounted thereon to vibrate, and the large-particle medicinal pieces in the primary vibration plate 202 slide into the crushing mechanism 3 .

Specifically, the primary vibration plate 202 is installed above the primary straight vibrator 201. The primary vibration plate 202 is surrounded on three sides and opened on one side. The open side is the discharge port of the primary vibration plate 202 and is located above the feed port of the crushing mechanism 3. The primary vibration plate 202 can temporarily store some large-grained decoction pieces therein. Driven by the primary vibrator, the primary vibration plate 202 vibrates to vibrate and slide the large-grained decoction pieces temporarily stored therein into the crushing mechanism 3.

Further, as shown in Figure 4, the crushing mechanism 3 includes a first motor 301, a transmission gear group 302, a crushing bin 303 and a crushing tool group 304 installed in the crushing bin 303; the first motor 301 can drive the crushing tool group 304 to rotate through the transmission gear group 302 to crush large-particle medicinal slices into small-particle medicinal slices.

Specifically, the crushing bin 303 is a rectangular frame with openings at the top and bottom. The crushing tool group 304 includes two crushing rollers rotatably connected to the crushing bin 303. Gears are connected to the ends of the crushing rollers. The first motor 301 drives one of the crushing rollers to rotate, driving the two crushing rollers to rotate towards each other, crushing the large-grained medicinal slices above downward into small-grained medicinal slices, and dropping them into the secondary feeding mechanism 4.

Furthermore, as shown in FIG. 5 , the secondary feeding mechanism 4 includes a secondary vibrator 401 and a secondary vibration plate 402 ; the secondary vibrator 401 is used to drive the secondary vibration plate 402 mounted thereon to vibrate, so that the small-particle medicinal pieces in the secondary vibration plate 402 slide into the weighing hopper 5 .

Specifically, the secondary vibration plate 402 is installed above the secondary direct vibrator 401. The secondary vibration plate 402 is surrounded on three sides and opened on one side. The open side is the discharge port of the secondary vibration plate 402 and is located above the feed port of the weighing hopper 5. The secondary vibration plate 402 can temporarily store some small-grained medicinal pieces therein. Driven by the secondary vibrator, the secondary vibration plate 402 vibrates to make the small-grained medicinal pieces temporarily stored therein vibrate and slide into the weighing hopper 5. The secondary direct vibrator 401 can adjust the vibration mode through the channel, and change the vibration frequency or vibration amplitude to adjust the feeding speed.

Furthermore, as shown in FIG6 , in order to enable the crushing part to replenish the small-particle pieces of medicinal materials to the adjusting part in time and avoid delaying the adjusting work, a photoelectric sensor 403 is installed in the secondary vibration plate 402 to feedback the material situation in the secondary vibration plate 402 to the primary feeding mechanism 2 to control the primary feeding mechanism 2 to feed or stop feeding.

When the photoelectric sensor 403 detects that there is a lack of small-particle medicinal pieces in the secondary vibration plate 402, a signal is fed back to the primary feeding mechanism 2, and the primary feeding mechanism 2 and the crushing mechanism 3 start to operate, crushing the large-particle medicinal pieces into small-particle medicinal pieces and feeding them into the secondary vibration plate 402.

Furthermore, the discharge port of the secondary vibration disk 402 is also equipped with a rotatable flow limiting plate 404 for adjusting the opening and closing degree of the discharge port. The flow limiting plate 404 can restrict the maximum adjustment flow rate of the medicinal pieces in the secondary vibration disk 402. On the one hand, it can make the feeding flow rate of the secondary feeding mechanism 4 uniform, and on the other hand, it can further improve the adjustment accuracy.

Specifically, the flow limiting plate 404 can be set as a movable baffle installed at the discharge port of the secondary vibration disk 402. The opening and closing degree of the discharge port of the secondary vibration disk 402 can be controlled by adjusting the baffle, which is equivalent to installing a valve at the discharge port to control the maximum flow rate of the material.

Further, as shown in FIG. 7 , the weighing hopper 5 includes a weighing hopper box 502 , a weighing hopper door 503 , and a door opening mechanism 504 , which are integrally mounted on a weighing sensor 501 .

Specifically, the weighing door 503 is rotatably mounted on the bottom of the weighing box 502, and is opened and closed by the door opening mechanism 504. The weighing sensor 501 is used to weigh the weight of the small-particle decoction pieces entering the weighing box 502, and feed the weighing information back to the secondary feeding mechanism 4.

When the weight of the small-particle pieces of medicinal material in the weighing hopper 5 reaches the required weight in the dispensing information, the secondary feeding mechanism 4 stops feeding into the weighing hopper 5. At the same time, the door opening mechanism 504 controls the hopper door 503 at the bottom of the weighing hopper box 502 to open, and all the medicinal materials flow out of the weighing hopper box 502. The hopper door 503 is arranged at the bottom of the weighing hopper box 502, which is conducive to emptying the medicinal materials, avoiding the medicinal materials remaining in the weighing hopper box 502, and further improving the dispensing accuracy.

Further, the door opening mechanism 504 includes a second motor 505, a spring, a cam 506 mounted on the motor shaft, and a double rocker mechanism 507 rotatably connected to a frame outside the weighing bucket door 503;

One end of the double rocker mechanism 507 is fixedly connected to the bottom of the weighing bucket door 503, and the other end is fixedly connected to the transmission plate 508 through a rod body;

The two ends of the spring are respectively connected to the weighing box 502 and the side of the weighing door 503 away from the rotating shaft to keep the weighing door 503 normally closed;

When the cam 506 rotates, it can drive the double rocker mechanism 507 through the transmission plate 508 to pull the weighing bucket door 503 to overcome the spring force to open the weighing bucket door 503.

It is understandable that the door opening mechanism 504 may be constructed in various ways, for example, a cylinder may be used to control the opening or closing of the weighing bucket door 503;

Specifically, the cylinder is arranged on the side of the weighing bucket door 503, and one end of the cylinder is connected to the weighing bucket door 503 through a rotating shaft, and the other end is rotatably connected to the weighing bucket box 502 through a rotating shaft; when the cylinder is extended, the weighing bucket door 503 rotates downward around the connection point between it and the weighing bucket box 502 to open; when the cylinder is contracted, the weighing bucket door 503 rotates upward around the connection point between it and the weighing bucket box 502 to close.

The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
