Problems solved by technology

Its advantage is that the structure is simple, but when the particles travel through the torsional vibration in the V-shaped sorting groove (mostly the spiral V-shaped ring groove), there is generally no inter-particle spacing, otherwise stacking phenomenon often occurs (especially the torsional vibration Improper adjustment, when the particle feeding speed is too high), when the particles fall through the photoelectric detection area, there will be ghost images, no intervals, and scattered (parts do not enter the photoelectric counting area), resulting in counting errors
In addition, there are difficulties in the versatility and adaptability of the V-shaped sorting groove to particles of different varieties and sizes; and the AC resonance noise of the electromagnet torsion vibrator is large, the faster the feeding speed, the greater the noise, and it is difficult to increase the counting speed. Runs for a long time and is prone to heat

Embodiment 1

[0049] Such as Figure 1-3 As shown, the present invention is composed of multiple systems, including: a preset counting system, a re-inspection counting system, an electronic control system, and the like.

[0050] Turntable oblique scraping photoelectric automatic particle counting instrument, the particle counting instrument includes:

[0051] A. The preset counting system includes a rotary table feeding device, a flow adjustment device, a photoelectric counting sensor device, and a positioning floating device for the feeding tank. The description and working process of each device are as follows:

[0052] 1. Turntable grain supply device, including conical feed cylinder 8, grain supply trough plate 3 set at the bottom of the conical feed cylinder, grain supply turntable 4 set under the grain supply trough plate 3, grain supply motor bearing seat 5 , turntable bearing 7, for grain stepper motor 6. A turntable bearing 7 is installed on the upper part of the grain supply mot...

Embodiment 2

[0104] On the basis of Embodiment 1 of the present invention, an electronic balance is configured again, and this instrument just can become a thousand-grain weight meter or a hundred-grain weight meter. The balance is arranged at the lower end of the grain discharge slide 20, and the grain-loading box is placed on the balance, and the balance is used to weigh the weight of the grains. Example: The preset number is set to 1000, and the number of rapeseed seeds after the actual re-inspection and counting is exactly 1002, which is 3.87 (g) after weighing. From the calculation formula: weight (g) / number of re-inspected grains×1000=thousand grain weight (g / 1000 grains), it can be known that the thousand grain weight of the rapeseed=3.87g / 1002×1000=3.86g / 1000 grains.

Embodiment 3

[0106] The instrument of Embodiment 1 of the present invention is placed on an automatic assembly line to form an automatic packaging device. A control line is drawn out from the numerical control circuit of the instrument to be connected with the automatic assembly line control circuit. Every time a round of preset counting starts, the assembly line is instructed to move, and the sub-packaging container (or other sub-packaging bags, etc.) is moved to the particle discharge slide 20 times and then stops to receive the falling particles. At the beginning of the next round of preset counting, the instruction assembly line will move again, and the next sub-packaging container will be moved to 20 times of the discharge slide to realize automatic sub-packaging.

Abstract

The invention provides a turntable-inclined scratching type photoelectric automatic particle counter aiming at the defects of electromagnet torsional vibration type particle counters which are the most commonly adopted at home and abroad at present and on the basis of a principle that particles can be automatically moved, sorted in order and spaced by the inclined scratching of a turntable. By the particle counter, the particles automatically moved, sorted in order and absolutely spaced (unless abnormal factors such as viscosity, blockage and the like) by using the turntable and a slot disk, necessary and reliable light-transmission clearances are provided for precise photoelectric counting, and a noisy electromagnet torsional vibration disk or mechanisms which generate particle spacing such as complicated escapements or apertures are not needed.

Description

technical field [0001] The invention relates to the technical field of automatic metering, packaging and control of granular materials, and is a novel, efficient and accurate instrument for automatic counting or predetermined amount counting of granular materials. Background technique [0002] Automatic counting of pellets or predetermined amount counting is an important link in the automation of metering control. Such as counting or sorting of crop seeds in agriculture (for example: quantitative seed packaging, measurement of thousand-grain weight of seeds, separation and counting of male and female silkworm eggs, precise seeding of seeders...); such as metering control of various grains in industry (Example: Quantitative packaging and counting of pills, pearls, etc....). At present, there are many types of automatic grain counting instruments or equipment at home and abroad, which can generally be divided into two categories. [0003] One is the static measurement type o...
