AI Technical Summary
The current method of sampling incoming tobacco shreds for cigarette making machines mainly relies on manual sampling, which leads to production interruptions, damage to sealing, moisture loss and impurity contamination, affecting the quality of tobacco shreds, and is also inefficient.
Design a tobacco shred sampling device that uses a negative pressure generator to provide sampling power. By setting a sampling port on the side wall of the cigarette machine's hopper and combining it with a separator, the tobacco shreds and airflow are separated, ensuring that the sampling process is sealed and reliable and does not interfere with normal production.
It enables efficient and accurate tobacco sampling without affecting production, ensuring sample representativeness, avoiding moisture loss and impurity contamination, and improving sampling efficiency and accuracy.
