Modification of Equipments to Produce Water-soluble Glue-added Filter Rod in ZL21 Filter Rod Maker

When water-soluble glue-added filter rod is produced in ZL21 filter rod maker,the high moisture content,high viscosity and poor fluidity of the glue causes some troubles in machine operation,such as the glue is not evenly applied,the dried glue tends to buildup on the pump body and resulting in frequent pump damage, copper pipes rust,and the filter rods are liable to be distorted by oven-drying. Therefore,ZL21 filter rod maker and oven were improved as following:raising the rotation speed of applicator motor from 1400 to 2800 r/min; increasing the number of hole line on the applicator disk from 1 line to 3 lines;replacing the gear pump with a peristaltic pump for glue supplying;using plasticized net pipe for glue applying and recycling;adding wire filter and arc-shaped opening roll;optimizing oven parameters. After improving,the results of practical application showed that the normal running of ZL21 filter maker was achieved when producing water-soluble glue-added filter rod,the machine efficiency reached over 90%,the average rate of qualified products was up to 97% and over.
