Description

Technical Field

[0001] The utility model relates to a metering and packaging device, in particular to a medicine divider which can divide Chinese medicine pieces equally according to weight. Background Art

[0002] When pharmacists pick up Chinese herbal medicine slices according to the prescriptions written by doctors, they usually weigh the same Chinese herbal medicine slices in multiple doses at once according to the total amount, and then divide the weighed Chinese herbal medicine slices equally into each dose. In the process of dividing the medicine, pharmacists often use visual inspection, manual weighing and other methods to divide the Chinese herbal medicine slices equally. This method of dividing the medicine has low accuracy, so that the dosage of the same Chinese herbal medicine slice in each dose cannot be equal, which not only has the risk of affecting the efficacy of the medicine, but also makes the pharmacist's work more arduous. CN 108891641 A discloses a Chinese medicine equal-amount dispensing mechanism, comprising a medicine material crushing mechanism, a powder medicine temporary storage bin, a quantitative dispensing mechanism and a dispensing mechanism, wherein a screen is arranged between the medicine material crushing mechanism and the powder medicine temporary storage bin, and the quantitative dispensing mechanism is arranged at the bottom of the powder medicine temporary storage bin; the dispensing mechanism comprises a main channel, and 7 branch channels are arranged below the main channel, wherein the 7 branch channels are 7 fan-shaped channels formed by dividing an annular channel into seven equal parts, and a dispensing motor is arranged at the center of the 7 fan-shaped channels, and a conical material guide cylinder protruding upward is arranged above the dispensing motor, and the main shaft of the dispensing motor protrudes to the upper end of the material guide cylinder, and a material-selecting wire protruding radially is arranged on the main shaft, and the invention realizes the rapid dispensing of Chinese medicine through a series of operations such as grinding, quantitative dispensing, and equal-amount dispensing, and greatly improves the efficiency of Chinese medicine dispensing. However, the Chinese medicine equal-amount dispensing mechanism can only be used for dispensing 7 doses of Chinese medicine, and cannot meet the dispensing of Chinese medicine pieces of other doses. CN213543779 U discloses a Chinese medicine fast weighing machine, comprising: a medicine feeding box, a shearing wheel, a driving box, a mounting plate, a through hole, a conveyor belt, a lower end rotating shaft, a spring, a driving box, a connecting plate, a medicine dispensing box, a stepping motor, a rotating shaft, a baffle, an operating panel, a support, a partition, an electronic scale, a medicine dispensing box, a handle, and a recycling box; the medicine feeding box is equipped with a shearing wheel; the mounting plate is fixed to the lower end of the medicine feeding box through a connecting plate, the medicine dispensing box is a rectangular frame with both upper and lower ends open, the medicine dispensing box is composed of a mounting plate and two horizontal plates, the stepping motor is installed on the side of the medicine dispensing box, one end of the stepping motor is connected to the rotating shaft, and the two ends of the rotating shaft are installed on the two side surfaces of the medicine dispensing box; the electronic scale is installed on the right side of the bottom plate of the support, the medicine dispensing box is placed on the electronic scale, the medicine dispensing box is equipped with a handle for the staff to grab, and the recycling box is used to place excess medicinal materials; the device can realize the fast weighing of Chinese medicine and improve the efficiency of taking medicine. Although the Chinese medicine fast weighing machine can meet the needs of dispensing Chinese medicine slices of any number of doses, it is difficult to accurately control the amount of medicine put into the medicine box during the medicine dispensing operation because the medicine box is placed on the electronic scale and the weight of the medicine box is weighed. The only way is to collect the excess Chinese medicine through the recycling box and recycle the excess Chinese medicine. This is not only cumbersome to operate, but also adds the step of returning the excess Chinese medicine to the medicine cabinet. In addition, the Chinese medicine will impact the electronic scale at the moment it falls into the medicine box, affecting the accuracy of the electronic scale measurement. Utility Model Content
