Strand tension balancing device of filter rod forming machine

Abstract

The invention provides a strand tension balancing device of a filter rod forming machine, which is characterized in that a strand is pulled out in advance, the tension of the strand entering the forming machine is constant, and the filling density of the strand is controlled to be stable in a small range, so that the produced filter rod suction resistance CPK value is improved. According to the technical scheme, the device comprises an anti-overturning device, a strand guide roller and a tension detecting device which are sequentially arranged along a movement track of a strand belt, wherein an automatic flying cleaning device is arranged below the strand guide roller; the anti-overturning device comprises a blowing pipe, an air chamber and a pressing plate, wherein the blowing pipe is communicated with the air chamber, and a flow channel for the strand to pass through is formed between the air chamber and the pressing plate; the tension detecting device comprises a supporting rod, a detection cross rod and a pressure sensor, wherein the detection cross rod and the pressure sensor are arranged on the supporting rod; the strand belt bypasses the detection cross rod; the automatic fly cleaning device comprises a cavity, wherein one side of the cavity, away from the strand guide roller, is connected with a high-pressure air pipe, and one side of the cavity, close to the strand guide roller, is provided with a plurality of gaps arranged at intervals.

Description

technical field [0001] The invention belongs to the technical field of cigarette machinery, and in particular relates to a tow tension balance device of a filter rod forming machine. Background technique [0002] The draw resistance of a cigarette is formed by the superimposition of the draw resistance of the filter section and that of the cigarette, so a stable filter section draw resistance is an important factor to ensure the stability of the draw resistance of a cigarette. The change of the pulling force of the tow will bring about the change of the suction resistance of the filter rod, thereby affecting the suction resistance of the cigarette, and will have a certain influence on the taste of the cigarette. The greater the pulling force of the tow, the smaller the filling density of the tow, the smaller the suction resistance, and vice versa. Therefore, the stability of the tow when it enters the forming machine is very important. But because the tow package is in the...
