Technical Field

The utility model relates to the technical field of medicinal material dispensing technology, and in particular to a Chinese medicine decoction piece feeding device.

Background Art

The preparation of Chinese herbal medicine slices requires the preparation of Chinese herbal medicines of different weights according to the prescription. In recent years, the manual method of picking medicines in traditional Chinese medicine pharmacies has been gradually replaced by automated Chinese herbal medicine slice preparation devices due to its disadvantages in efficiency, precision, and manual labor intensity.

However, the existing Chinese herbal medicine dispensing device is only provided with a primary feeding structure. During dispensing, the primary feeding mechanism needs to transport all the Chinese herbal medicines in the entire silo each time it moves, and transport all the herbal medicines in the silo to the outlet of the dispensing device. The transported Chinese herbal medicines are not only heavy in weight but also have a long transportation distance, which is prone to drug jams.

Utility Model Content

The utility model aims to provide a Chinese herbal medicine feeding device to solve the technical problem that when a primary feeding mechanism in the prior art feeds medicine, not only the quality of the Chinese herbal medicine fed is large but also the feeding distance is long, and medicine is easily stuck.

DETAILED DESCRIPTION

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 provides a Chinese medicine slice feeding device, comprising a hopper 1 arranged obliquely downward, the hopper 1 is used to store Chinese medicine slices, and the discharge port of the hopper 1 is arranged at a lower end thereof;

The inner wall at the bottom of the hopper 1 is provided with at least a primary feeding mechanism 2 and a secondary feeding mechanism 3 along the flow direction of the medicinal pieces;

When the downstream cavity of the hopper 1 is out of medicine, the primary feeding mechanism 2 can transport the medicine pieces in the upstream cavity of the hopper 1 to the downstream secondary feeding mechanism 3;

The secondary feeding mechanism 3 is used to transport the medicinal pieces in the downstream cavity to the discharge port, so that the medicinal pieces leave the hopper 1 from the discharge port.

The Chinese medicine slice feeding device adopts a multi-stage feeding mechanism to replace the existing feeding method with only one-stage feeding mechanism 2.

The traditional feeding mechanism has only one level of feeding mechanism 2, which will transport all the pieces in the silo forward during feeding. The Chinese herbal medicines transported at one time are not only heavy in weight but also have a long transport distance, which causes the problem of drug jam in the dispensing module.

The Chinese herbal medicine feeding device adopts the method of cooperating with at least two-stage feeding mechanisms. When the two-stage feeding mechanism is adopted, the two-stage feeding is utilized as a buffer, and the first-stage feeding mechanism 2 is used to feed the material to the downstream second-stage feeding mechanism 3. When the Chinese herbal medicine dispensing module triggers the shortage of material, the second-stage feeding will feed the material in the downstream cavity into the dispensing module.

Not only is the mass of the Chinese medicinal beverage delivered by each level of the feeding mechanism 2 small, but the distance delivered by each level of the feeding mechanism 2 is short, which can effectively prevent the medicine from being stuck in the dispensing module.

Furthermore, the primary feeding mechanism 2 includes a first motor 5 fixedly mounted on the lower side of the bottom plate of the hopper 1, a first eccentric wheel 6 mounted on the shaft of the first motor 5, and a first feeder 4 arranged on the upper side of the bottom plate of the hopper 1;

The end of the first feeder 4 is fixedly connected with a first ring 7, and the first ring 7 is sleeved on the first eccentric wheel 6;

A first limiting plate 8 is also fixedly connected to the upper side of the bottom plate of the hopper 1, and a circular hole surrounding the outer side of the first circular ring 7 is provided on the first limiting plate 8;

The first eccentric wheel 6 is used to drive the first ring 7 to shake circumferentially around the circular hole in a plane, so as to transport the slices upstream of the hopper 1 to the secondary feeding mechanism 3 downstream;

The first limit plate 8 is covered with a partition 19, which is fixedly connected to the hopper 1. The partition 19 can prevent the first ring 7 from moving upward, so that the first ring 7 can only swing within the range of the circular hole. At the same time, the partition 19 can also separate the Chinese herbal medicine pieces from the first limit plate 8 and the first ring 7 and other structures to prevent the Chinese herbal medicine pieces from interfering with the operation of the mechanism.

The working process of the above-mentioned primary feeding mechanism 2 is as follows: the first motor 5 drives the first eccentric wheel 6 to rotate, and the first eccentric wheel 6 can drive the first ring 7 mounted thereon to swing circumferentially around the inner wall of the circular hole when rotating, thereby making the first feeder 4 fixedly connected to the first ring 7 swing synchronously with the first ring 7, so as to transport the Chinese herbal medicine pieces in the upstream cavity to the downstream cavity.

The secondary feeding mechanism 3 has the same structure as the primary feeding mechanism 2 , and includes a second motor 14 , a second eccentric wheel 15 , a second feeder 16 , a second limiting plate 17 and a second ring 18 .

The feeding method is the same, the second motor 14 drives the second eccentric wheel 15 to rotate, and the second eccentric wheel 15 can drive the second ring 18 mounted thereon to swing around the inner wall of the circular hole when rotating, so that the second feeder 16 fixedly connected to the second ring 18 and the second ring 18 can swing synchronously, so as to transport the Chinese herbal medicine pieces in the downstream cavity to the outlet of the hopper.

Furthermore, in order to improve the feeding efficiency, an upright tooth piece 9 is fixedly provided on the first feeder 4 , and the tooth piece 9 is inclined toward the downstream direction of the hopper 1 .

Since the tooth piece 9 is inclined in the downstream direction and there is gravity, when the first feeder 4 moves in the upstream direction, it will not drive the Chinese herbal medicine pieces to move upstream;

When the first feeder 4 moves downstream, the tooth plate 9 can serve as an auxiliary plate to push the Chinese herbal medicine pieces downstream.

Furthermore, a primary sensor (11) is provided on the hopper (1) at the tail end of the primary feeding mechanism (2) for detecting whether the upstream cavity is short of material.

Specifically, a baffle 10 and a primary sensor 11 are provided above the tail end of the primary feeding mechanism 2, and the primary sensor 11 is installed outside the hopper 1;

The upper end of the baffle 10 is rotatably connected to the top of the hopper 1 through a rotating shaft, one end of the rotating shaft extends to the outside of the hopper 1, and a light shielding sheet 20 is fixedly connected to the end;

When the baffle 10 falls naturally, the light shielding sheet 20 shields the primary sensor 11, so as to feed back a signal indicating that the upstream cavity is short of material to the central control system;

When the baffle 10 is lifted by the material in the upstream cavity, the light shielding sheet 20 rotates to avoid the primary sensor 11, so as to feed back a signal indicating that there is material in the upstream cavity to the central control system.

Specifically, when the upstream cavity is short of material, the baffle 10 naturally drops under the action of gravity. At this time, the shading sheet 20 connected to the same rotating shaft as the baffle 10 just blocks the sensor 11. The blocked first-level sensor 11 sends a signal of lack of material to the central control system. At this time, it is necessary to replenish Chinese herbal medicine slices into the hopper 1.

During the process of replenishing Chinese herbal medicines, since the hopper 1 is tilted, the Chinese herbal medicines have a downward trend, which will lift up the baffle 10 located at the tail end of the primary feeding mechanism 2, that is, the end of the upstream cavity. The baffle 10 is lifted up, which drives the shading sheet 20 to rotate through the rotating shaft, and the shading sheet 20 rotates to avoid the primary sensor 11. At this time, the primary sensor 11 will send a signal to the central control system to stop replenishing.

Furthermore, the primary sensor 11 is configured as a slot-type photoelectric sensor. When the light shielding sheet 20 is located in the groove of the slot-type photoelectric sensor, the blocked slot-type photoelectric sensor sends a signal of material shortage to the central control system.

Optionally, the primary sensor 11 may also be configured as a photoelectric sensor, a proximity switch or a Hall sensor.

Furthermore, a secondary sensor 12 is provided on the side wall of the hopper 1 above the tail end of the secondary feeding mechanism 3 for detecting whether there is a lack of material in the downstream cavity.

Optionally, the secondary sensor 12 is configured as a through-beam sensor, a proximity switch or a Hall sensor.

When the secondary sensor 12 detects that the downstream cavity is out of material, it can feed back the signal to the central control system, so that the primary feeding mechanism 2 can operate to feed material to the downstream cavity.

Furthermore, an opening is provided at the top of the upstream cavity of the hopper 1, and the opening is covered with a transparent cover plate 13 that can be opened and closed.

The transparent cover 13 is provided to facilitate observation of the material in the hopper 1 , and the transparent cover 13 can be opened to facilitate maintenance of the feeding mechanisms and other components at various levels in the hopper 1 .

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.
