An Improved Parallel Drum Mechanism of Protos Cigarette Making Machine

Abstract

An improved PROTOS cigarette machine parallel drum mechanism, including a parallel drum and a suction valve, in the axial direction, a plurality of first suction holes (5), The second air suction hole (6), the middle circumferential oblong groove (7) is arranged between the first air suction hole and the second air suction hole, the first air suction hole and the second air suction hole are about the middle circumferential oblong groove Symmetrically arranged, the first air suction hole and the second air suction hole in the axial direction are located in the same concave portion. Parallel drums change the shape and geometric dimensions of the original suction channel, increase the diameter area and unobstructed performance, and improve the stability and reliability of the arrangement of the three filter segments in the parallel drums. The suction valve can provide suction to the parallel drums in advance, increase the time for the filter segments on both sides to move to the center line, and make the filter segments move closer to the middle in advance, effectively reducing the phenomenon that the filter segments cannot be in place after entering the parallel drums. Thereby reducing the frequency of filter failure.

Description

technical field [0001] The invention relates to the field of cigarette equipment, in particular to an improved PROTOS cigarette machine parallel drum mechanism. Background technique [0002] PROTOS70 crimping unit is a world-renowned cigarette production equipment designed and manufactured by a German company. It is currently manufactured by Changde Tobacco Machinery Co., Ltd. in my country. The domestic model is YJ17-YJ27. In practical applications, the YJ17-YJ27 crimping unit has operational Simple, stable operation, convenient maintenance and many other advantages. [0003] During the working process of the six-slit filter supply system of YJ27 tipping machine, the three staggered filter sections in the parallel drum are arranged in a row under the action of negative pressure air, and the parallel drum receives the filter from the upstream misplaced drum. , arranged in a row and then passed to the downstream acceleration drum, the design of the groove of the upstream disl...

AI Technical Summary

Problems solved by technology

The prerequisite is to ensure that the movement of the filter tip section does not interfere with the shape of the drum, but the filter tip does not fit perfectly in the wheel groove, and there is a certain gap

When the negative pressure system sucks the air in the cavity of the parallel drum through the suction channel, the external air will be supplemented through this gap. If the area of ​​the suction channel of the parallel drum is small and the suction flow is low, it cannot quickly A negative pressure lower than atmospheric pressure is formed, causing the displacement of the filter section to be slow and unable to reach the designated position

At the same time, the silk wadding and nozzle rod debris produced by the upstream cutting process are also easy to block the suction channel of the parallel drum, so that the filter cannot be in place.

In addition, the filter section located in the middle section will also be difficult to fix because the parallel drum has only one positioning suction hole, and it is prone to position deviation during the high-speed rotation of the parallel drum. When the filter is transported to the acceleration drum , it will be collided and skewed by the guide rails on both sides of the acceleration drum, causing the filter section to fall on the acceleration drum, seriously affecting the operating efficiency of the equipment
