Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

Referring to Figures 1-3, a device for dispensing traditional Chinese medicine pieces includes a body 1, a bracket 2 and a feeding table 3 are fixedly welded on the body 1, and a primary conveyor belt 4 and a secondary conveyor belt 5 are respectively provided in the body 1, The first-level transmission belt 4 is used to convey scattered pieces of traditional Chinese medicine, the second-level conveyor belt 5 is used to convey the medicine cans 15, and the upper end of the body 1 is bolted with a servo motor 6. A screw rod 7 is rotated between the bracket 2 and the screw rod 7 is threadedly connected with a nut 8. A through port 9 is opened in the feeding table 3, and two opening and closing plates 10 are connected to the pin shaft in the through port 9. The nut 8 and A traction rod 11 is connected between the two opening and closing plates 10 , a weight sensor 12 is arranged in the two opening and closing plates 10 , and a PLC controller 13 is fixedly installed on the upper end of the body 1 , and the optional product model of the weight sensor 12 is LTY -87GR weight measuring equipment, PLC controller 13 can choose automatic intelligent control equipment with model TB02-serie.

3, the opening 9 has a circular structure, and the two opening and closing plates 10 are semicircular structures. When the two opening and closing plates 10 are horizontally abutted, the opening 9 can be sealed to prevent the Chinese medicine pieces from falling.

It is further explained that both the primary conveyor belt 4 and the secondary conveyor belt 5 are equidistantly conveyed, and during the time period when the PLC controller 13 transmits the turn-on command to the servo motor 6, the primary conveyor belt 4 and the secondary conveyor belt 5 are both temporarily stopped. state, to ensure that the Chinese herbal medicine pieces on the primary conveyor belt 4 and the medicine tank 15 on the secondary conveyor belt 5 are still.

The bracket 2 and the feeding table 3 are arranged from top to bottom, and the feeding table 3 is located directly below the bracket 2. The primary conveyor belt 4 and the secondary conveyor belt 5 are arranged from top to bottom, and the primary conveyor belt 4 is located obliquely above the feeding table 3. A transport plate 14 is inclined between the primary conveyor belt 4 and the opening 9 to ensure that all the pieces of Chinese medicine can be moved to the opening and closing plate 10. The secondary conveyor belt 5 is located directly below the feeding table 3, and the secondary conveyor belt 5 is placed on the medicine tank. 15.

The lead screw 7 is arranged vertically, and one end of the lead screw 7 is connected with the output shaft of the servo motor 6 .

The number of the draw bars 11 is two, and the two ends of the two draw bars 11 are respectively connected to the nut 8 and the opening and closing plate 10 in rotation. , so that the opening and closing plate can be opened and closed by 10 pieces.

The weight sensor 12 and the PLC controller 13 are electrically connected to the servo motor 6. It should be noted that the two gravity sensors 12 respectively perform weight detection on the Chinese herbal pieces on the two opening and closing plates 10, and then feed back the total weight to the The PLC controller 13 is in order to judge whether the set weight threshold is reached, so as to decide whether to open the two opening and closing boards 10 .

The utility model can illustrate its functional principle through the following operation modes:

The scattered Chinese herbal pieces flow through the primary conveyor 4 to the transport plate 14 , because the transport plate 14 is inclined and moved to the opening and closing plate 10 in the feeding table 3 under the inertia and gravity of the Chinese herbal medicine pieces.

In this case, the two opening and closing plates 10 are in a state of being horizontally offset, that is, the through port 9 is sealed.

When more pieces of traditional Chinese medicine move to the opening and closing plate 10, and its own weight squeezes the opening and closing plate 10, so that the weight sensor 12 measures the weight of the traditional Chinese medicine pieces on the opening and closing plate 10, when the weight reaches the set threshold value , and pass this information to the PLC controller 13 .

After the PLC controller 13 receives the information, it issues an opening command to the servo motor 6, the output shaft of the servo motor 6 drives the lead screw 7 to rotate, the nut 8 moves vertically downward on the lead screw 7, and the nut 8 passes through the traction rod 11 to align the two pieces. The opening and closing plates 10 are squeezed, so that the two opening and closing plates 10 are opened and deflected downward with their pin shaft connection ends as the fulcrum, and a certain amount of Chinese herbal medicine pieces on the opening and closing plates 10 move downward through the opening between the two opening and closing plates 10. .

The secondary conveyor belt 5 drives the medicine tank 15 to move horizontally, and is located directly below the port 9 , so that the Chinese herbal medicine pieces on the opening and closing plate 10 are all dropped into the medicine tank 15 .

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
