The sample container cup 2 falls back on the bracket 1, and the bracket 1 leaves with the sample container cup 2; the material is collected in a storage bin 9 or discharged to a belt conveyor 11 for industrial production, and the material is circularly and reciprocally operated.
Example 2
As shown in fig. 5, in this embodiment, the push rod mechanism 8 includes a driving component, a push rod 802 and a sliding cylinder 804, the push rod 802 includes a vertical sliding rod and a horizontal top plate disposed at the top end of the vertical sliding rod, the sliding rod at the lower end of the push rod 802 can slide up and down in the sliding cylinder 804, and the sliding cylinder 804 is vertically fixed on the other side of the bracket 7.

When the bracket 1 gradually approaches the discharging station, the proximity switch 6 senses the bracket 1, the bracket 1 stops moving, the stepping motor 809 starts moving to drive the rotating shaft 805 to rotate, so that the cam 806 rotates to push the push-pull rod 802 upwards, when the cam 806 moves to the limit, the stepping motor 809 stops, the push-pull rod 802 pushes the sample container cup 2 into the suction nozzle 3, and the sample container cup 2 is firmly adsorbed on the suction nozzle 3 due to the suction force. The vacuum material sucking mechanism 5 is electrified to start sucking materials, and the materials are conveyed into the vacuum cavity 502 along with the airflow through the material guide pipe 4; after the material sucking is completed, the stepping motor 809 is continuously started, the cam 806 is restored to the initial position, the push-pull rod 802 also slides along with the initial position to restore the original state, the sample container cup 2 falls back on the bracket 1, and the bracket 1 leaves with the sample container cup 2; the material is collected in a storage bin 9 or discharged to a belt conveyor 11 for industrial production, and the material is circularly and reciprocally operated.
Example 3
As shown in fig. 6, in this embodiment, the push rod mechanism 8 includes a push rod 802 and an electromagnet driver 803, the electromagnet driver 803 is disposed at the upper end of the other side of the support 7, the push rod 802 includes a vertical slide rod and a horizontal top plate disposed at the top end of the vertical slide rod, and the slide rod is connected to the driving end of the electromagnet driver 803. The electromagnet driver 803 is connected with the proximity switch 6, when the proximity switch 6 detects that the bracket 1 moves to the discharging station, the electromagnet driver 803 starts to be electrified to enable the slide bar to move upwards, the sample container cup 2 is jacked into the suction nozzle 3, and the sample container cup 2 is firmly adsorbed on the suction nozzle 3 due to suction. The vacuum material sucking mechanism 5 is electrified to start sucking materials, and the materials are conveyed into the vacuum cavity 502 along with the airflow through the material guide pipe 4; after the material suction is completed, the electromagnet driver 803 is powered off, the electromagnetic force disappears, and the push-pull rod 802 falls down to restore the original state; the sample container cup 2 disappears and falls back on the bracket 1 due to the suction force, and the bracket 1 leaves with the sample container cup 2; the material is collected in a storage bin 9 or discharged to a belt conveyor 11 for industrial production. And the operation is repeated in a circulating way.
In the above embodiments, the top plate of the push-pull rod 802 is provided with a high density sponge 801, which can prevent the sample container cup 2 from being damaged by rigid collision.
In the invention, the suction nozzle 3 in the vacuum suction mechanism 5 is a conical suction nozzle, the suction opening of the conical suction nozzle is equal to the cup opening of the sample container cup 2, and the inner wall surface of the conical suction nozzle adopts arc transition, so that the structure is more beneficial to the flow of air flow and materials, reduces the contact of the materials and the inner wall and falls back into the sample container cup 2, and improves the discharging and conveying efficiency. However, when the suction nozzle 3 adsorbs the sample container cup 2, no air flow will flow in the sample container cup 2, so that the material is difficult to be conveyed out of the sample container cup 2, and therefore, in order to make the material in the sample container cup 2 be conveyed out efficiently, as shown in fig. 7 and 8, the invention is provided with more than one circular or square ventilation small opening 201 at the cup opening of the sample container cup 2 or at the opening edge of the suction nozzle 3, and the aperture is preferably 2mm-6mm. This creates a high velocity air flow within the sample container cup 2, carrying material and transporting it out of the sample container cup 2.
Considering that when the push rod mechanism 8 pushes up the sample container cup 2, there is a certain probability of pushing up the sample container cup 2, at this time, if the suction opening of the conical suction nozzle is equal to the cup opening of the sample container cup 2, serious air leakage is caused to be too large, so that the air flow in the sample container cup 2 is weak, and the material conveying and sucking capacity is deteriorated, so that the suction opening of the suction nozzle 3 needs to be designed to be larger than the cup opening of the sample container cup 2, and the inner wall surface of the conical suction nozzle can also adopt arc transition, as shown in fig. 9, 10 and 11, so that even if the upper top of the sample container cup 2 is in biased contact with the suction nozzle 3, a large amount of air leakage is not generated due to a gap, and the small ventilation opening 201 is arranged at a position slightly upper than the contact position of the sample container cup 2 and the suction nozzle 3, because the suction nozzle 3 is in a conical inclined surface structure, the air flow coming from the small ventilation opening 201 can flow obliquely downwards, so that strong air flow vortex is easier to be generated, the material sucking capacity and the efficiency are greatly improved.
The above description is merely a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above examples. Modifications and variations which do not depart from the technical idea of the invention shall be deemed to be within the scope of the invention.
