Abstract

The invention discloses a process for producing a filter rod by utilizing a KDF4 forming unit. The process comprises the following steps: throwing raw tows into an AF4 tow opening device; after spraying a plasticizer, delivering the tows to the KDF4 forming unit by a delivering roller to produce the filter rod; after the filter rod is formed, detecting the filter rod, putting the filter rod into a disk and storing the filter rod; and then delivering the filter rod to a cigarette making machine. The process has the following beneficial effects: the process parameters are optimized; aiming at the tows of different specifications (such as 3.5Y34000, 3.0Y35000, 3.9Y31000, 3.0Y32000, 2.4Y34000 and the like), the optimal process parameter is screened out through experiments; the stability of indexes such as resistance to suction of the KDF4 forming unit and the yield of the filter rod produced by utilizing the KDF4 forming unit are improved on the original bases; and the purpose of reducingthe processing consumption is achieved.

Description

technical field [0001] The invention relates to a process for producing filter rods by using a KDF4 molding unit. Background technique [0002] The forming machine is a device for rolling tobacco tow (hereinafter referred to as tow) into a filter rod. KDF4 / AF4 is a new generation of high-speed filter rod forming unit produced by Hauni, Germany, with a maximum processing speed of 600 m / min. KDF4 is a filter rod rolling and slitting equipment designed with "PROTOS" cutter head, and AF-4 is its front tow opening equipment. The threaded pair of rollers placed vertically constitutes the AF4 tow stretching area. In the stretching zone, the bundled monofilaments are separated, and the tight network structure of the tow formed by crimping can be spread, but this short-term, ultra-high-speed network structure spreading is often accompanied by the non-equilibrium characteristics of internal stress. The tow then passes through the relaxation zone, which provides equilibrium time and...
