(3) drying the blasting beads: and placing the blasting beads in a material bin, opening an operation switch, and performing blasting bead drying through automatic control of a control system.
In order to realize the automatic control of the bead blasting and drying process, drying tests are carried out on bead blasting products for cigarettes to be dried in advance: the diameter of the bead blasting product is 2.8mm, the diameter before drying is 4.80 +/-0.15 mm, and in order to obtain the best product drying time and fan frequency (the fan frequency represents the air volume), a drying experiment is carried out: the normal air quantity is used for drying in the whole process for the first time, and the experimental result can show that the average drying time is short, but the qualified rate is low.
After the repeated drying process is analyzed, the shell wall material of the exploded bead loses most of moisture after the exploded bead is dried to the diameter of 3.6mm, but the shell is still soft, the movement track of the exploded bead in the drying chamber is larger under normal air volume, the mutual extrusion degree between the exploded beads is also larger, and therefore the qualified rate after drying is lower.
Therefore, after the air is dried to 3.6mm, the air volume is reduced, different air volumes are adjusted to carry out a plurality of tests, the test result shows that the qualification rate is obviously improved after the air volume is reduced, but the drying time after the air volume is reduced is obviously prolonged, and the operation efficiency of the drying equipment is influenced.
Further analysis of the drying process shows that after the blasting beads are dried to the diameter of 3.2mm, the blasting bead shells losing most of moisture have certain hardness and certain compression resistance values, so that the normal air volume is adjusted in the test, the test result shows that the qualification rate after the normal air volume is adjusted is basically the same as that before the adjustment, and the adjustment mode is effective.
Therefore, the drying process of the bead blasting comprises the steps of firstly drying with normal air quantity, then adjusting the air quantity to be small for drying, and then adjusting the air quantity to be normal for drying to finish drying.
The obtained time and air quantity parameters of the standard drying process of the bead blasting are used as data, a PLC (programmable logic controller) in a control system 10 is used for automatically controlling the drying process, as shown in figure 2, an operation switch is turned on, at the moment, a PLC in the control system 10 controls a fan to be started, the fan drives air to enter drying equipment to dry the bead blasting for the cigarettes, a timer arranged in the PLC starts to operate, when the air quantity needs to be adjusted by timing, the timer sends out a signal and feeds back the signal to the PLC, the frequency of the fan is adjusted by the PLC, and meanwhile, the timer continues to operate until the set stop time of the timer is reached, the timer outputs a signal and feeds back the signal to the PLC to control the fan to stop operating, and the drying process of the bead blasting for the cigarettes is completed.
