Negative pressure wind power supply method and device for coiler

Abstract

The negative pressure wind power supply method and device of the coiling unit relate to the field of wind conveying technology. The negative pressure wind power supply device of the coiling unit includes a fan and a dust collector which are individually configured for each coiling unit and connected sequentially from front to back through the wind power supply main pipe And the wind buffer, the wind buffer is connected with three wind power supply branch pipes, and the wind power supply branch pipe used to provide the negative pressure wind force for the coiling unit is equipped with a negative pressure attenuator and a wind speed balance unit. A wind pressure balancer is provided on the wind power supply branch pipe that the unit provides cigarette negative pressure wind power. Compared with the method of centralized wind power supply using two sets of centralized process wind power and wind power wire feeding system, the present invention independently provides the required negative pressure wind power for each coiling unit, and each coiling unit can work independently without affecting each other. It is conducive to the personalized production arrangement and production safety management of the factory, the workshop layout is more flexible, the adjustment is faster, and the later maintenance is more convenient.

Description

technical field [0001] The invention relates to the technical field of wind power conveying, in particular to a negative pressure wind power supply method and device for a crimping unit in a cigarette factory. Background technique [0002] In the cigarette factory, the lifting process from shredded tobacco to ribbon is mainly completed by process wind, and the process wind branch pipes of multiple crimping units are connected to the process wind main pipe in parallel. Since multiple coiling units are connected to the same process wind system, during the production process, the number of operating coiling units often changes, and the increase or decrease in the number of operating coiling units will cause system pressure to occur. Therefore, the process wind power control system often needs to drive the air supply device and the wind pressure balance device to balance the wind pressure of the pipeline to ensure the stable operation of the coiler. The control logic of the whol...

Problems solved by technology

In actual production, the number of cigarette machines in the wire-feeding state often changes, and the change in the number of cigarette machines that are feeding wire will inevitably cause changes in the wind speed in the wire-feeding pipeline of the system. Therefore, in the existing wind-driven wire-feeding system, It is often necessary to adjust the wind speed in the pipeline through the air supply device and the wind speed balance unit, and the control logic of the wind wire feeding system is also relatively complicated

[0003] More importantly, since each coiling unit is connected to two systems of process air force and wind force wire feeding system, and the process wind force and wind force wire feeding system correspond to multiple coiling units respectively, the complex pipe network structure limits the layout of the factory In addition, each coiling unit will affect each other, which is not conducive to production scheduling and personalized production arrangements. At the same time, the adjustment of system air pressure and air volume requires a very complicated control method. When adjusting the wind pressure and air volume of a certain coiling unit, it takes a short period of time from the system startup adjustment to the set wind pressure and air volume, and there is a certain reaction lag
