Air distribution plate for preparing double-filter-capsule filter rod and preparation device

Abstract

The invention discloses an air distribution plate for preparing double-filter-capsule filter rod and a preparation device. The air distribution plate comprises a plate body, an inside suction slot, anoutside suction slot and an alternating air blowing structure, wherein the inside suction slot and the outside suction slot are both arranged on the plate body, an arc-shaped groove body is coaxial with the plate body, a radius of the inside suction slot is less than that of the outside suction slot, and one end of the inside suction slot is radially flush with one end of the outside suction slot; the central angle of the outside suction slot is 90-340 degrees, the central angle of the inside suction slot is at least 30 degrees, and at least 30 degrees smaller than that of the outside suctionslot; the alternating air blowing structure is arranged at one end of the inside suction slot radially flush with the outside suction slot; the inside suction slot and the outside suction slot are connected with a vacuum pump, the vacuum pump provides negative pressure for adsorbing negative pressure of a filter capsule; the alternating air blowing structure is connected with the air source, andprovides positive pressure for transferring the filter capsule to next process.

Description

technical field [0001] The invention belongs to the technical field of double-explosion bead filter rod preparation, and in particular relates to a double-explosion bead filter rod preparation air distribution plate and a preparation device. Background technique [0002] Popping beads for cigarettes is a kind of capsule with a semi-permeable membrane or a sealed capsule formed by wrapping solid, liquid or gas with natural or synthetic polymer materials. It is one of the technologies used for cigarette aroma compensation. [0003] Popping bead filter rod is a filter rod prepared by embedding popping beads in the filter rod during the preparation process of the filter rod. The filter rod is evenly cut into filter tips containing popping beads. Beads, for a single burst bead filter. The double blasting bead filter rod means that the number of popping beads in the filter rod of the same length is twice the number of popping beads in the single popping bead filter rod, and the f...

AI Technical Summary

Problems solved by technology

The blasting bead filter rod prepared by this method includes two layers of filter rod forming paper and one layer of cigarette tipping paper. The number of layers of paper is large, which is not conducive to the general laser drilling of cigarettes to improve the ventilation rate, and also causes waste of materials.

Moreover, there are many processing procedures for the double blasting bead filter rod, which is likely to cause damage to the blasting beads in the filter, which in turn leads to a high reject rate of the double blasting bead filter, and also easily leads to a reduction in production efficiency.

[0005] In summary, the existing technology of double-exploded bead filter rods has problems such as low production efficiency, waste of materials, high scrap rate, unfavorable laser drilling to improve the ventilation rate of the filter, etc., and there is still no effective solution. Program
