Detailed Description

Referring to the attached drawings 1 to 3, the filter stick linear feeding and sorting device of the embodiment comprises an installation bottom plate 1, and a discharging mechanism 2, a linear feeding mechanism 4, a filter stick detecting mechanism 5 and a sorting mechanism 6 which are arranged on the installation bottom plate.

The discharging mechanism 2 comprises a hopper 21 and a guide rail 22 arranged below a discharging port of the hopper 21, and the guide rail 22 is used for receiving the filter stick falling from the discharging port. The discharge ports are used for dropping the filter sticks in the hopper 21 into the guide rails 22 one by one.

In order to meet the stability of the filter stick in the guide rail, the guide rail 22 adopts a circular arc groove structure, so that the guide rail can be suitable for filter stick samples with various diameter specifications. And an air connector 23 is connected to the guide rail 22, and the air connector 23 is communicated with a negative pressure airflow hole inside the groove of the guide rail. The negative pressure air flow hole can prevent the filter stick from shaking left and right inside the groove, and the stability of the filter stick is ensured.

In this embodiment, the linear feeding mechanism 4 includes a linear motor 41, a push rod seat 42 and a push rod 43, the push rod 43 is connected to a driving block of the linear motor 41 through the push rod seat 42, and the setting direction of the push rod 43 is the same as that of the guide rail 22, so that the push rod 43 drives the filter stick on the guide rail 22 to enter the filter stick detection mechanism 5 under the driving of the linear motor 41.

In a preferred embodiment, the linear feeding mechanism 4 further includes a slide rail 44 consistent with the moving direction of the push rod 43 and a slide block 45 disposed on the slide rail 44, and the push rod seat 42 is fixedly connected to the slide block 45. The arrangement of the sliding block 45 and the sliding rail 44 can be used for ensuring the stability of the movement of the push rod 43 and reducing the shaking problem.

And the length of the push rod 43 is larger than that of the discharge hole, namely, the length of the filter stick. Thus, when the push rod 43 pushes the filter stick to the filter stick detection mechanism 5 and the sorting mechanism 6, the push rod 43 occupies the position of the filter stick on the guide rail 22, and the phenomenon that the filter stick is inclined when falling down or the push rod 43 cannot return to the initial position to be clamped is avoided.

In this embodiment, the sorting mechanism 6 includes a discharging plate 61, a left channel plate 62 and a left air cylinder 63 which are arranged on the left side of the discharging plate 61, and a right channel plate 65 and a right air cylinder 66 which are arranged on the right side of the discharging plate, and the top of the discharging plate 61 is arranged in an arc groove structure for receiving the filter stick pushed by the push rod 43 and passing through the filter stick detection mechanism 5. The extending plate 64 of the left air cylinder 63 is arranged relative to the filter stick above the discharging plate 61, and a left channel is formed between the left channel plate 62 and the discharging plate 61. The extending plate 67 of the right air cylinder 66 is also arranged relative to the filter stick above the discharging plate 61, and a right channel is formed between the right channel plate 65 and the discharging plate 61. Thus, after the filter stick is detected by the detection mechanism 5, the filter stick is pushed to the upper part of the discharging plate 61 by the push rod 43, and the left air cylinder 63 or the right air cylinder 66 is controlled to be started according to the detection result. If the filter stick is qualified, the left air cylinder 63 is controlled to be started, and the extension plate 64 of the left air cylinder pushes the qualified filter stick above the discharge plate 61 into the right channel; and if the filter stick is unqualified, controlling the right air cylinder 66 to start, and pushing the unqualified filter stick above the discharge plate 61 into the left channel by the extension plate 67 to finish the filter stick sorting.

In this embodiment, the discharging plate 61, the guide rail 22 and the feeding channel in the filter stick detecting mechanism 5 are all on the same straight line, so that the purpose that the push rod 43 pushes the filter stick from the guide rail to the discharging plate is achieved.

Similarly, a negative pressure airflow hole 68 is formed in the circular arc groove structure of the discharging plate 61, and the negative pressure airflow hole 68 is communicated with an air joint 69 for ensuring the stability of the filter rod in the groove of the discharging plate.

The filter stick linear feeding and sorting device pushes filter sticks linearly, has the advantages of stable movement speed and high feeding efficiency, can realize a feeding detection speed of 120 counts/minute, and can ensure stable data in a sample detection process, so that the measurement result is more reliable.
