Problems solved by technology

During the process of mechanical packaging, various factors such as the type of drug, particle size, the amount of remaining drug in the hopper, drug humidity, viscosity, etc. will affect its feeding speed, resulting in unstable feeding speed and changes in feeding speed. It will cause the magnitude of the impact force to change, and the change of the magnitude of the impact force will cause errors in the measurement of the weight of the medicine in the dispensing tray, resulting in inaccurate and uneven dispensing weights

Embodiment 1

[0016] In embodiment 1, such as figure 1 As shown, the present invention includes a frame body, a lower hopper 2, a runner 11 and a weighing assembly. In order to facilitate the display of the internal structure, the frame structure has been partially omitted in the figure, and only the part connected to other structures is drawn, that is, the straight line with hatching in the figure (except for the section line). The frame structure is used to support, connect and fix other structures. Since the specific structure of the frame is determined by the position and size of other structures and has no impact on the working principle of the present invention, its specific structure will not be repeated.

[0017] The lower hopper 2 is in the shape of a funnel with a thick top and a thin bottom, and is used to accommodate medicines to be dispensed. The periphery of the lower hopper 2 is provided with a hopper spring 1, and the lower end of the hopper spring 1 is fixedly installed on...

Embodiment 2

[0022] In embodiment 2, such as figure 2 , 3 As shown, the present embodiment includes a frame body, a lower hopper 2, a runner 11 and a weighing assembly. Wherein the lower hopper 2, the runner 11 and their auxiliary structures and connections are the same as those in Embodiment 1, and will not be repeated in this embodiment. The frame structure is adaptively changed according to the change of the structure of the weighing assembly. The difference between this embodiment and Embodiment 1 mainly lies in the change of the weighing assembly.

[0023]The weighing assembly is located below the runner 11 and includes No. 1 rack 21 , No. 2 rack 22 , No. 1 crossbeam 17 , No. 2 crossbeam 15 and No. 3 crossbeam 14 . The No. 1 disc rack 21 and the No. 2 disc rack 22 are fixed on the rack body (or it can be said to be a part of the rack body). The No. 1 rack 21, the No. 2 rack 22 and the No. 1 beam 17 are placed obliquely, the front is high and the rear is low. The No. 1 rack 21 is ...

Embodiment 3

[0027] In embodiment 3, such as Figure 4 As shown, the present embodiment includes a frame body, a lower hopper 2, a runner 11 and a weighing assembly. Wherein the lower hopper 2, the runner 11 and their subsidiary structures and connections are the same as those in Embodiment 1, and will not be repeated in this embodiment. The frame structure is adaptively changed according to the change of the structure of the weighing assembly. The difference between this embodiment and Embodiment 1 mainly lies in the change of the weighing assembly.

[0028] The weighing assembly includes No. 1 rack 21, No. 2 rack 22, No. 3 beam 14 and No. 4 beam 30, wherein No. 1 rack 21, No. 2 rack 22 and No. 3 beam 14 and No. 3 crossbeam 14's subsidiary structure and connection relationship thereof are the same as embodiment 2, and the present embodiment is no longer repeated. The middle position of the No. 4 beam 30 is hinged with the frame body, wherein a torsion spring is provided at the hinge, a...

Abstract

The invention discloses quantitative automatic subpackaging equipment and belongs to the field of pharmaceutical machinery. The quantitative automatic subpackaging equipment is characterized by comprising a frame, a feed hopper, a turning wheel and a weighing and loading assembly; the periphery edge of the feed hopper is provided with hopper springs; a movable discharge port is arranged below the feed hopper; the lower end of the feed hopper is provided with a fixed rack fixedly connected with the feed hopper; the discharge port is in rigid connection with one end of a fixed rod; the other end of the fixed rod is hinged to the lower end of the fixed rack; an arc-shaped rod is provided with a series of leaf springs; the side, opposite to the discharge port, of the fixed rack is provided with a counter weight; a first collection hopper is arranged at the discharge port; the turning wheel is located below the arc-shaped rod; a series of blades are arranged on the periphery of the turning wheel; an opening of the lower end of the first collection hopper is located above the blades of the turning wheel; a second collection hopper is located below the first collection hopper. Compared with the prior art, the quantitative automatic subpackaging equipment has the characteristic that weighing is convenient and accurate.

Description

technical field [0001] The invention relates to a pharmaceutical machine, in particular to a quantitative automatic packaging device. Background technique [0002] The powdered or granular bulk drug products produced in pharmaceutical factories or other factories are subpackaged according to a certain weight, so as to facilitate subsequent processing, sales, use, transportation and other operations. There are two ways of dispensing and mechanical dispensing. Traditional manual dispensing is time-consuming and laborious, while mechanical dispensing of Chinese medicines, especially Chinese medicinal materials or mineral medicines, will cause impact on the dispensing tray when they fall into the dispensing tray, and the impact will be symmetrical. Interference with the heavy process. In order to make the weight accurate, it is common practice to measure the size of the impact force through experiments, and then add the size of the impact force on the basis of the actual weight...
