转盘振动喂丝机吸丝口的改进

Improvement of Suction Inlet in Vibrating Cut Tobacco Feeder

风力送丝系统中的转盘振动喂丝机在运行过程中,转盘中的烟丝受振动易发生烟丝分层,导致卷烟机落料器吸入烟丝结构差别大、吸丝时间长、卷烟质量不稳定等问题,为此,对转盘振动喂丝机的吸丝口进行了改进。改进措施为:①采用浮动式吸丝口替换喂丝机的固定式吸丝口;②拆除振动系统的减速电机,取消转盘的振动功能。改进后有效解决了转盘振动喂丝机的烟丝分层问题,卷烟机落料器内烟丝碎丝率变异系数降低了0.23,吸丝时间减少了13s;烟支端部落丝量降低2.41mg/支,吸阻标准偏差降低51.2Pa,烟支重量标准偏差降低5.5mg/支。实际测试结果表明,风送到卷烟机落料器内的烟丝结构更加均匀,提高了烟支卷制质量的稳定性。

The cut tobacco in the rotational table in vibrating feeder in a pneumatic feeding system is liable to be segregated because of vibration, which results in longer suction time and negatively affects the consistence of cigarette quality. Therefore, the feeder＇ s suction inlet was improved ： 1 ） replacing the fixed suction inlet with a suspensible suction inlet ; 2） removing the speed reducing motor from the vibrating system to disable the vibration function of the rotational table. After improving, the problem of cut tobacco segregation was well solved, the coefficient of variance of short strands proportion in feeding airlock reduced by 0.23 ; suction time shortened by 13s; tobacco loss from cigarette end decreased by 2.41 mg/cig, standard deviations of pressure drop and cigarette weight dropped by 51.2 Pa and 5.5 mg/cig, respectively. The test results showed that the structure of cut tobacco pneumatically fed to the cigarette maker was more uniform and cigarette quality was more-consistent.
