[0029] The transmission mechanism 20 is mounted on the base plate 10 and drives the filter cartridge discharge assembly 50 and the mixing assembly 30. The mixing assembly 30 is mounted on the transmission mechanism 20 and mixes the filter cartridge to prevent clogging.

[0030] The transmission mechanism 20 includes a fixed plate 201, a support plate 202, a driving component 203, and a transmission chain 204.

[0031] The fixed plate 201 is arranged on the bottom plate 10, the supporting plate 202 is arranged on the fixed plate 201, the driving component 203 is arranged on the supporting plate 202, and the conveying chain 204 is sleeved on the mixing assembly 30 and the material guiding mechanism 502.

[0032] It should be noted that the fixed plate 201 described in the embodiment is a plate arranged vertically on the top wall of the bottom plate 10, and the mixing assembly 30, the feeding assembly 40 and the filter core discharging assembly 50 are arranged on the fixed plate 201 respectively.

[0035] It should be noted that the outer casing 501 is a circular casing, and the top wall and the bottom wall of the circular casing are respectively provided with an inlet and an outlet. The filter core falls into the material guiding mechanism 502 from the inlet on the top wall of the outer casing 501. The pneumatic feeding mechanism 503 moves up and down with the rotation of the material guiding mechanism 502, so that the pneumatic port repeatedly acts on the filter core limiting mechanism 404, and the filter core is blown into the pipette tip.

[0036] In one embodiment of the present application, as shown in Figure 1 The material guiding mechanism 502 comprises a movable shaft 5021, a rotating disc 5022 and a material collecting groove 5023.

[0037] The movable shaft 5021 is arranged at the output end of the driving component 203, and the movable shaft 5021 is rotatably arranged on the fixed plate 201.

The multiple groups of material collecting grooves 5023 are arranged in an annular array on the rotating disc 5022.

[0038] It should be noted that the depth of the aggregate tank 5023 is the same as the height of the filter element, and the outer shell 501 and the aggregate tank 5023 have a gap, so that the aggregate tank 5023 does not collide with the outer shell 501 during rotation, and the filter element does not fall off.

[0039] In one embodiment of the present application, as shown in Figure 1 The air pressure feeding mechanism 503 includes a feeding piece 5031, a buffer rod 5032, and a reset component 5033.

Therefore, when the rotating disc 5022 rotates, it drives the aggregate tank 5023 to rotate synchronously, and the aggregate tank 5023 abuts against the baffle 50315 during rotation, and then the baffle 50315 drives the fixed block 50311 to move upward first, and when the fixed block 50311 moves to the highest position, the baffle 50315 rotates under stress and is separated from the aggregate tank 5023.

The blind groove is arranged in the positioning groove 4033, and the limiting hole 4034 is opened in the blind groove.

[0051] In an embodiment of the present application, as shown in Figure 1 and Figure 3 The filter core limiting mechanism 404 includes an outer sleeve ring 4041, an inner material guiding end face 4042 and a material guiding pipe 4043.

[0053] It should be noted that the outer diameter of the outer sleeve ring 4041 is matched with the gap of the blind groove, and the material guiding pipe 4043 is inserted into the limiting hole 4034. The pipette tip is mounted in the limiting hole 4034, and the pipette tip moves synchronously when the moving plate 402 moves.

[0054] In an embodiment of the present application, as shown in Figure 1As shown, the mixing assembly 30 comprises an outer frame 301, a transmission shaft 302 and a mixing component 303.

[0055] Wherein, the outer frame 301 is arranged on the fixed plate 201, the transmission shaft 302 is rotatably arranged on the fixed plate 201, and the transmission chain 204 is sleeved on the transmission shaft 302, and the mixing component 303 is arranged on the transmission shaft 302.
