(1) Theoretical output: The theoretical output of a card refers to the output of a card that rotates continuously within the unit's elbow without any time loss.
The doffer is directly proportional to the number of teeth of the fast and slow teeth, and the theoretical output of carding (kg / hour) is directly proportional to the number of fast and slow teeth and the number of slivers. The higher the theoretical output of the cotton machine.
(II) Actual output The actual output refers to the output after considering various parking factors.
Actual output (kg / set) = theoretical output x production efficiency
To increase production, in addition to adopting new technologies and increasing doffer speed and sliver rations to a limited extent, in the normal production, the equipment production efficiency, equipment productivity, equipment operation rate, and equipment utilization rate should be mainly improved.
(3) Production efficiency Production efficiency refers to the percentage of actual output and theoretical output of operating equipment.
It can be seen from the formula that to increase the actual output, it is necessary to increase the production efficiency or the theoretical output. The theoretical output is directly proportional to vehicle speed. For carding machines, increasing the output can increase the doffer speed and the number of sliver slivers. However, too high the doffer speed will cause the cotton neps to increase impurities and reduce the quality. Increasing the number of slivers will affect the subsequent process Processing will have an impact. Therefore, the more appropriate way to increase the actual output is to increase the production rate.
There are many factors that affect the prostitute rate of card production. For example, the card has a "big head stop, operation and maintenance stop, repair of a broken car stop, swap roller stop, stranded belt stop, and multiple machine care overlapping stop. , Copy the needle to stop the table, etc. Therefore, to improve production efficiency, we must minimize _ the above parking time.
