Filter stick suction resistance stabilizing device and method thereof

Abstract

The invention discloses a filter stick suction resistance stabilizing device, which comprises a lifting device used for perfroming lifting movement; a tow traction device used for applying traction force to the tows output by a tow feeding device; a tow buffer device comprising an arc-shaped tow storage groove extending downwards from the bottom of the tow traction device, wherein at least one buffer stop lever is fixed to the inner side of an arc-shaped tow storage groove, and a gap allowing tows to penetrate through is formed between the buffer stop lever and the arc-shaped tow storage groove; a tow supporting frame, wherein the first end of the tow supporting frame is installed on a machine base of the filter stick forming device, the second end of the tow supporting frame extends to the position above the tow traction device, and tows pulled out by the tow traction device penetrate through the tow buffering device, then extend upwards, bypass the second end of the tow supporting frame and then are conveyed to a feeding port of the filter stick forming device. According to the invention, balanced tension distribution and consistent tow density in the tow conveying process can beensured, so that the filter stick processing quality is improved.

Description

technical field [0001] The invention relates to a cigarette filter rod production system, in particular to a device and method for stabilizing filter rod suction resistance. Background technique [0002] Filter rod production is a pre-process link in the cigarette production process. The filter rod forming process is to process and roll the fiber tow of filter material for cigarettes into a round rod with filtering performance and a certain length. During the production process, under the action of self-weight pressure and the tension force of the packing belt on the upper surface, bottom surface, middle and surrounding tow bundles of the newly opened tow package, it is easy to cause uneven density or uneven pressure. When the tow enters the opening machine through the high cantilever, different parts of the tow are subjected to different tensions. In the part with high tension, the tow will be stretched and become longer and thinner, and the tow will open after the second s...

AI Technical Summary

Problems solved by technology

During the production process, under the action of self-weight pressure and the tension force of the packing belt on the upper surface, bottom surface, middle and surrounding tow bundles of the newly opened tow package, it is easy to cause uneven density or uneven pressure. When the tow enters the opening machine through the high cantilever, different parts of the tow are subjected to different tensions. In the part with high tension, the tow will be stretched and become longer and thinner, and the tow will open after the second stage of opening. The loosening effect is not good, so it is easy to enter the tension area due to stretching, excessive opening, etc., which will affect the quality of the filter rod suction resistance, and the suction resistance of the filter rod will change greatly, or the filter rod will shrink, and the soft mouth will be unqualified, etc. Happening
