复合滤棒中心线胶间断式上胶系统的设计及应用

Design and application of periodic internal glue-line application system for combined filter rod maker

为解决复合滤棒中心线胶施加过程中胶水无法间断喷涂等问题,采用高速电磁阀技术设计了一种中心线胶间断式上胶系统。该系统以电磁胶枪为基础,通过电气控制系统调节胶水压力和胶枪上胶参数,可精确控制胶水喷涂位置以及滤棒胶点数量、间距和大小,并可实现不同规格复合滤棒的快速匹配和应用。以KDF2滤棒成型机组为对象进行测试,结果表明:该系统在200 m/min生产速度下运行稳定,生产的含空腔结构的二元和三元复合滤棒在空腔位置无胶点、无胶水残留;在施胶区域,滤棒胶点数量无缺失或增加,胶点偏移距离控制在2 mm内。该技术可为结构多元化复合滤棒的生产应用提供支持。

In order to apply internal glue-line periodically for combined filter rod maker,a glue application system was designed on the basis of high speed solenoid valve technology.With an electromagnetic gluing gun,the system precisely controlled the gluing position,the number,space and size of glue spots in filter rod via regulating glue pressure and gluing gun parameters with an electrical control system.Furthermore,the system could be rapidly adjusted to adapt to combine filter rods of different specifications.Taking a KDF2 filter rod maker as an object,the system was tested,the results showed that it ran stably at the production speed of 200 m/min;no glue spot or glue residue was found at the cavity portion of dual or triple filter rod;and no missing or excess glue spots in the gluing area of filter rod;and the position deviation of glue spots was controlled within 2 mm.This technology provides a support for the production and application of combined filter rods with diversified structure.
