Background

The PROTOS70 is one of main force equipment for cigarette production, and consists of VE, SE, MAX parts, wherein VE is mainly responsible for tobacco shred supply, and in the system, tobacco shred forming and weight control play an extremely critical role, and tobacco shreds are subjected to certain treatment to form formed tobacco shred bundles in an air suction chamber for supplying SE to complete subsequent process treatment. The tobacco shred bundles formed by sucking the tobacco shreds are uneven in tobacco shred quantity, and if the tobacco shreds are directly rolled, the weight deviation of cigarettes is overlarge. The formed tobacco bundles are further processed by adopting a leveling device, so that the tobacco bundles are basically uniform. The trimming cutter disc is arranged on the leveler, after the tobacco shred density of the tobacco rods is measured and calculated through microwave detection, if deviation exists after the tobacco shred density is compared with a set value, the servo motor receives signals and enables the leveler to rotate slightly around the rotating shaft through the lifting pull rod, and therefore the trimming cutter disc of the leveler moves up and down, and redundant tobacco shreds under the tobacco shred sucking belt are trimmed as required.

The patent is composed of a servo motor, a servo controller, an adjusting track for driving the silk suction belt to move up and down, a rotating shaft, a cam and the like. The servo motor of the system is connected with a cigarette making machine weight control system through a servo controller. The system has a complex structure, the servo controller chicken servo motor needs to be reset, the adjusting position is at the tail end of the silk suction belt, the weight control is corresponding and the effect is delayed, the lag of the weight adjustment of the cigarettes is easy to be caused, the cigarettes cannot be timely adjusted to a set value when the weight deviation is large, and the cigarettes vibrate near the set standard value, so that the stability is poor. CN201220672754.8 is generally composed of a main machine of the cigarette making machine, a silk suction belt, a negative pressure cavity and a universal coupling. The universal coupling is connected with a servo motor which is connected with a servo controller, and the servo controller is connected with an encoder. The system has excessive links, the system is in an unstable state, signal transmission delay is easy to occur, and program writing and synchronous adjustment of a server and an encoder are easy to approach a set value accurately and rapidly when weight deviation is large due to excessive links.
