The medicaments are liquid, solid and powdery, and the manual pouring and metering of the medicaments are troublesome, so that a special medicament meter is required. The screw metering device in the prior art is only suitable for powder blanking metering and lacks the application of centering pill agent blanking metering. Therefore, a screw type metering mechanism which is suitable for traditional Chinese medicine pills and can accurately meter the feeding amount is needed.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and aims to provide a screw type metering mechanism which is suitable for traditional Chinese medicine pills and can accurately meter the feeding amount.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a screw type traditional Chinese medicine pill metering mechanism comprises a motor, wherein the motor is composed of a servo motor, a first rack for supporting is arranged on the lower side of the motor, the motor is connected with a screw rod penetrating through the middle of the first rack, and a second rack is arranged on the lower side of the first rack in a connecting mode through a telescopic mechanism; the screw rod penetrates through the second rack and coaxially penetrates through the material pipe in the middle of the second rack, the screw rod is provided with a spiral groove capable of enabling pills to be arranged in a single row, and the bottom of the screw rod is provided with a receiving table for receiving the pills; the top of the material pipe is provided with a filling hopper fixed with the second frame, the top side of the filling hopper is provided with a material supplementing opening, and the radial distance between the inner diameter of the material pipe and the outer diameter of the screw rod is smaller than half of the diameter of the pill.
Furthermore, a bottom support fixed with the first machine frame is arranged on the lower side of the second machine frame, and a guide rail penetrating through the second machine frame is arranged between the bottom support and the first machine frame.
Compared with the prior art, the invention has the following beneficial effects:
1. the invention can carry out the blanking and the measurement of the traditional Chinese medicine pills, according to the size of the pills to be blanked, the diameter of the spiral groove of the screw is processed to be slightly larger than that of the pills to be blanked, and the radial distance between the inner wall of the material pipe and the outer wall of the screw is smaller than half of the diameter of the pills, so that the pills to be blanked can be thrown into the spiral groove of the screw by the filling hopper and are arranged in a single row. During blanking, the second rack is driven to ascend by the telescopic mechanism, the bottom end of the screw rod is exposed, the servo motor is opened to rotate the screw rod, pills blocked by the receiving platform at the bottom of the screw rod fall under the influence of centrifugal force and downward driving force of the screw rod, the number of rotation turns of the screw rod is recorded through a rotary encoder of the servo motor, the number of pills which can be arranged through a single spiral groove is combined with the number of rotation turns of the screw rod, and then the number of pills to be blanked is measured.
2. In order to avoid that the radial distance between the material pipe and the screw rod is too large, the mechanism vibrates too much or the outside is collided to enable the pills to fall down on the material pipe, the radial distance between the inner diameter of the material pipe and the outer diameter of the screw rod is smaller than half of the diameter of the pills, the pills can be guaranteed to move between the spiral groove of the screw rod and the inner wall of the material pipe, and the radial distance between the material pipe and the screw rod is not enough to enable the direct pills.

FIG. 2 is a schematic sectional view of a screw according to the present invention;
FIG. 3 is a schematic view of the screw with the material pipe extending out of the bottom of the screw.
Description of reference numerals:
the method comprises the following steps of 1-a motor, 2-a screw, 3-a first frame, 4-a second frame, 5-a telescopic mechanism, 6-a material pipe, 7-a filling hopper, 8-a guide rail, 9-a bottom support, 21-a receiving table, 22-pills and 71-a material supplementing opening.
Detailed Description
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1 to 3, a screw type traditional Chinese medicine pill metering mechanism comprises a motor 1, wherein the motor 1 is composed of a servo motor, a first rack 3 for supporting is arranged at the lower side of the motor 1, the motor 1 is connected with a screw 2 penetrating through the middle part of the first rack 3, and a second rack 4 is arranged at the lower side of the first rack 3 through a telescopic mechanism 5; the screw rod 2 penetrates through the second rack 4 and coaxially penetrates through the material pipe 6 in the middle of the second rack 4, the screw rod 2 is provided with a spiral groove capable of enabling pills 22 to be arranged in a single row, and the bottom of the screw rod 2 is provided with a receiving table 21 for receiving the pills 22; the top of the material pipe 6 is provided with a filling hopper 7 fixed with the second frame 4, the top side of the filling hopper 7 is provided with a feeding port 71, and the radial distance between the inner diameter of the material pipe 6 and the outer diameter of the screw rod 2 is less than half of the diameter of the pill 22; a bottom support 9 fixed with the first frame 3 is arranged on the lower side of the second frame 4, and a guide rail 8 penetrating through the second frame 4 is arranged between the bottom support 9 and the first frame 3.
The spiral groove of the screw rod 2 can form a receiving platform 21 capable of preventing pills 22 from falling by avoiding milling to the bottom end of the screw rod 2, and meanwhile, the round receiving platform 21 capable of being extended into the material pipe 6 is additionally arranged at the bottom of the screw rod 2 to receive the pills 22. Wherein, telescopic machanism 5 can constitute by cylinder or electric telescopic handle, comes control second frame 4 to reciprocate, and telescopic machanism 5 is the cylinder in this embodiment.
Before the feeding device works, pills 22 to be fed are fed into the material pipe 6 through the feeding opening 71, so that the pills are arranged between the screw 2 and the inner wall of the material pipe 6 in a single row along the spiral groove of the screw 2. After the completion of the supplement of the discharged pills 22, the telescopic mechanism 5 lifts the second frame 4 to drive the material pipe 6 to ascend, so that a single row of pills 22 arranged along the spiral groove of the screw rod 2 are exposed out of the material pipe 6. The starting motor 1 rotates and controls the servo motor to rotate at a constant speed, so that the pills 22 exposed out of the material pipe 6 are separated from the spiral groove under the action of centrifugal force, the pills 22 not exposed out of the material pipe 6 overcome static friction force to rotate downwards under the influence of the downward driving force of the screw rod 2 until the bottom of the material pipe 6 is exposed out of the spiral groove, and discharging is completed. During blanking, the number of the rotation turns is controlled by a rotary encoder on the servo motor according to different loading amounts of the material to be blanked and the number of pills 22 which can be contained in the single-turn spiral groove, so that the pill blanking metering is completed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
