Description

Particle automatic dispensing device

technical field

The invention relates to a device in the technical field of daily necessities, in particular to an automatic granular packing device.

Background technique

At this stage, the separation and counting of small solid particles is a big problem, and many times, in the grain, food and medical and health industries, it is necessary to separate the same kind of solid particles to obtain a one-by-one count. Particle state and count. For example, in the process of taking medicine, pharmacists need to count out a specific number of pills and give them to patients in accordance with the prescription requirements. Or in the candy reward mechanism, children can get a candy when they reach the goal. Or in the process of grain testing, corn, soybeans, wheat and other grains need to be separated into grains for testing. Now, these operations are usually done manually, which is time-consuming and labor-intensive, and the probability of errors is also greatly increased. At present, many product solutions for separation are mostly large-scale industrial products for specific sizes and shapes. Possessing a large volume, it cannot be easily used in daily life.

After searching the prior art, it was found that US Patent Document No. US7,258,248B2, published on August 21, 2007, discloses a tablet cassette for medicine packing machine for medical packaging machines. There is a medicine tank inside The conical rotating body, through the rotation of the rotating body, the tablets falling on the conical surface fall into the hole groove, and then the hole groove rotates at a slower speed than the conical rotating head, and then the tablets are taken one by one Fall down along the hole of the corresponding size. However, during the packing process of this technology, the particles come into frequent contact with the escape recess, which on the one hand increases the probability of particle damage, and on the other hand directly leads to the residue of the particles. In order to avoid the mixed use of particles, one kind of medicine tank can only correspond to one kind of medicine, and the packing efficiency is too low. Particles need to be moved for a long time to complete the packing and counting. When there are many kinds of objects to be processed and the quantity is small, the processing efficiency is low . Other existing technologies also have similar relative motion separation mechanisms, but their effects are difficult to meet people's needs for easy, quick and hygienic packaging.

Chinese Patent Document No. CN2764504Y, published (announcement) date 2006.03.15, discloses a particle single particle separator, including a bracket, two upper and lower discs are arranged on the bracket, the upper part is a separating disc, the lower part is a rotating disc, and the separating disc The bottom surface of the separator is provided with a spiral curved groove, and a material inlet is opened on the top surface of the separation disk. The end of the spiral curved groove of the separation disk is a material outlet, and the rotating disk is placed on the speed regulating motor. However, the disadvantage of this technology is that the separation effect on some solid particles is not ideal. If two tablets are stacked or two capsules are parallel, they cannot be separated.

As shown in FIG. 2 and FIG. 3 , the screw inlet 5 is located in the middle of the upper cover 1 , and the screw inlet 5 is a curved surface structure. In this embodiment, the central axis of the spiral inlet 5 coincides with the central axis of the turntable.

As shown in FIG. 1 and FIG. 4 , the cross-section of the turntable 3 is a multi-inflection curve l. In this embodiment, the dispersing slope 4 of the turntable 3 is composed of several annular rotating surfaces 41 , 42 , 43 whose edges are connected. Each annular rotating surface is inclined upward or downward at intervals and is not horizontal.

As shown in FIG. 4 , the innermost and outermost annular rotating surfaces, that is, the horizontal inclination and the rotational speed of the first annular rotating surface 41 and the third annular rotating surface 43 and the radius of the position of the particles satisfy the following relationship:

Among them: ω is the angular velocity of the turntable, θ is the radial inclination of the dispersion slope, μ is the friction coefficient between the drug particles and the turntable, and R is the radius of the particle location. Different horizontal inclinations in the design maintain a certain sliding friction between the particles and the outside of the deflector, and the change affects the velocity of the particles. The upper limit of the rotational speed of the turntable is determined by the radius and θ of the outer edge of the turntable.

In this embodiment, 5°<θ<45°, μ is determined by the medicine and the material of the turntable, and the radius of the outer edge of the turntable is determined according to the design requirements.

As shown in FIG. 3 , the deflector 2 is vertically arranged, and its horizontal section is an involute curve or a curve similar to an involute, and its lower edge coincides with the surface undulation of the turntable. The deflector plate 2 horizontal section curves in the present embodiment satisfy: r (θ)=a+b*(θ), wherein: r (θ) represents the distance of the point on the curve according to the central axis, a represents the radius of the center circle, and b Indicates the magnitude of the deflection of the curve.

In this embodiment: a and b are determined by the size of the particles.

The separation process of this device is as follows: the medicine is input from the screw inlet of the upper cover, and the turntable drives the medicine to enter the lowest point near the center of the turntable from the screw inlet, and the screw inlet controls the flow of medicine. The channel formed climbs up to the edge of the turntable under the push of the deflector. The turntable adopts local turning and sinking to adjust the pose of the drug particles and eliminate possible drug stacking. While the drive sensor control module controls the speed of the turntable to separate medicines, it also controls the rotation speed of the annular medicine storage compartment. The two speeds cooperate to ensure that the medicine falls into a specific medicine compartment after separation.
