A shredded tobacco conveying control device for a shredded wire feeding machine of a cigarette making machine

Abstract

The invention discloses a tobacco shred conveying control device of a shred feeder of a cigarette making machine set. The tobacco shred conveying control device comprises a master control device, a first servo motor used for driving a shred throwing roller and a tobacco shred conveyer belt to operate, a second servo motor used for driving a picker roller to operate, a third servo motor used for driving a high-angle shred lifting belt to operate, a fourth servo motor used for driving a needle roller and a spiral stem returning mechanism to operate and four servo controllers. The four servo controllers are all electrically connected with the master control device through buses. The signal output ends of the four servo controllers are electrically connected with the first servo motor, the second servo motor, the third servo motor and the fourth servo motor respectively. By means of the tobacco shred conveying control device of the shred feeder of the cigarette making machine set, the distributional evenness of tobacco shreds in the conveying process can be improved, the positional accuracy of the thick shred end is improved, the empty head rate is lowered, the weight evenness of cigarettes can be improved, the disadvantages of being underweight, overweight, soft and hard are reduced, bamboo joint cigarettes are avoided, and product quality is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco equipment, in particular to a shredded tobacco conveying control device for a shredded wire feeding machine of a cigarette making machine. Background technique [0002] In tobacco production, the wire feeder of the coiling unit is a key part of the whole unit, for example, figure 1 It is the structural diagram of the wire feeder VE70 of the coiler PROTOS70, as shown in figure 1 Shown: shredded tobacco is sucked into the shredded tobacco cavity 1 by the wind suction pipe, when the shredded tobacco material level on the metering roller 3 is lower than the photoelectric switch 2, the cylinder controls the blanking gate to open, and the quantitative shredded tobacco is put down. When the shredded tobacco material level in the storage area 6 was lower than the high-level photoelectric switch 5, the metering roller 3 moved and cut the wire, and the steep angle ribbon 26 lifted the shredded tobacco in t...

AI Technical Summary

Problems solved by technology

[0003] At present, the motors driving the needle rollers and the steep-angle conveyor belt in the wire feeder of the cigarette making machine are DC motors. The shredded tobacco conveyor belt, silk spinning reel, and wire throwing roller rotate at a constant speed with a power frequency of 50Hz, and the conveyor belt runs at a high speed. There may be a certain amount of slippage, which will make the cut tobacco uneven during the conveying process, and there will also be short spots, bamboo joints, soft spots and hard spots, etc., and because the spinning reel is rotated by a constant-speed motor with a power frequency of 50Hz Drive, when the speed of the vehicle is rising or falling, the needle roller will have a certain change with the speed of the vehicle, but the speed of the spinning reel will not change. The distribution of shredded tobacco will be uneven due to different brands, which will also cause short and uneven weight to a certain extent.

In addition, the shredded tobacco conveyor belt and the shredded wire throwing roller are driven by a motor with a constant power frequency of 50 Hz. During the process of rising and falling of the vehicle speed, the speed of the needle roller has changed, that is, the amount of shredded tobacco has changed, but the amount of shredded tobacco has changed. The constant speed of the conveyor belt and the throwing roller will cause uneven distribution of shredded tobacco when the ribbon is sucked up, resulting in uneven weight distribution and weight stability cannot be guaranteed
