SUMMERY OF THE UTILITY MODEL
The utility model 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 blanking amount.
In order to achieve the above purpose, the technical scheme of the utility model is realized like this:
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 utility model discloses following beneficial effect has:
1. the utility model discloses can carry out the unloading and the measurement of traditional chinese medicine pellet, according to the size of treating unloading pellet, treat unloading pellet diameter slightly big for the helicla flute diameter ratio with the helicla flute processing of screw rod to make the radial distance between material pipe inner wall and the screw rod outer wall be less than half of pellet diameter, let and treat that unloading pellet can drop into the helicla flute single-row of following the screw rod by the filling hopper and arrange. 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. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic sectional view of the screw rod of the present invention;
fig. 3 is a schematic structural view of the material pipe extending from the bottom of the middle screw rod of the present invention.
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 accompanying drawings in conjunction with embodiments.
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 utility model discloses well screw rod 2's helicla flute accessible is avoided milling to 2 bottoms of screw rod to form and is blockked that pellet 22 drops connect platform 21, also can accept pellet 22 through add the circular platform 21 that connects in the stretch into the pan feeding pipe 6 in the screw rod 2 bottom simultaneously. 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.
