Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a cutting device. Background Technology

[0002] Existing methods for cutting cell gel blocks are divided into two types: wire cutting and blade cutting. Wire cutting utilizes physical tension, applying pressure through a taut wire or steel wire. Blade cutting utilizes the sharpness and shearing force of a metal blade to cut and slice the wax block.

[0003] Existing methods for cutting cell gel blocks all involve manual cutting, which has the following problems:

[0004] 1. It is difficult to guarantee that every cut will be perfectly flat when cutting manually, especially for wax blocks with uneven texture.

[0005] 2. Using a sharp blade to operate by hand is extremely dangerous, as it can easily cause the blade to slip and result in serious cuts, posing a significant risk of biosafety exposure.

[0006] There is an urgent need for a cutting device that can automatically cut cell gel blocks. Utility Model Content

[0033] Beneficial effects:

[0034] Compared to traditional manual cutting, this equipment reduces manual operation and minimizes the biohazard to laboratory personnel during processing. Motor-controlled cutting saves labor, eliminates the need for operator training, and reduces time wasted on repetitive tasks.

[0035] Since the centrifuge tube contains cell blocks needed for the experiment, the centrifuge tube, which is fixed inside the centrifuge tube limiting groove, is driven by the centrifuge tube moving mechanism to move back and forth, thereby realizing the movement of the centrifuge tube to the cutting station and out of the cutting station.

[0036] To achieve automatic cutting to a fixed size, the drive motor of the wire cutting mechanism transmits rotational motion to the wire cutting head, enabling linear motion of the wire cutting head and precise cutting of the cell blocks at the bottom of the centrifuge tube.
