AI Technical Summary
In existing technologies, when transferring dry gel blocks by suction, the dry gel particles break into small particles, resulting in non-compliance with size standards and reducing the utilization rate of the dry gel.
A tooling flipping device is adopted, which is detachably connected to the rollers of the gel tooling through the tooling connection mechanism. The rotating disk drives the gel tooling to rotate slowly, so that the dry gel block tilts and slides into the downstream tooling, avoiding violent collisions.
This improves the utilization rate of dry gel and avoids the formation of dry gel particles that do not meet size standards.
