Description
Technical Field
The invention relates to the field of cigarette industry, in particular to a self-cleaning system and a control method for a negative pressure filter screen of a cut tobacco collecting box of a cigarette making machine.
Background
The cigarette making machine mainly comprises a feeding part (VE), a cigarette part (SE) and a tipping part (MAX). The main function of the feeding part is to send the cut tobacco in the cut tobacco room to the cut tobacco collecting box through the cut tobacco sucking pipeline by using a wind power cut tobacco feeding system, and then the cut tobacco in the cut tobacco collecting box is conveyed to the cut tobacco sucking and forming mechanism through the cut tobacco loosening device. The negative pressure filter screen is arranged in the shred collection box, and when the tobacco shreds are sucked into the shred collection box by negative pressure, the negative pressure filter screen intercepts the tobacco shreds to finish the one-time pneumatic shred feeding process.
During production, the process of wind-force wire feeding often needs to repeatedly suck, and tobacco stems or other foreign matters in tobacco shreds can cause abrasion or blockage to the negative pressure filter screen to a certain extent, so that the aging of the negative pressure filter screen can be accelerated. When the negative pressure filter screen is aged seriously, part of tobacco shreds are attached to the negative pressure filter screen, the permeability of the negative pressure filter screen is affected, wind power of a negative pressure pipeline is insufficient, and the wind power wire feeding effect is affected. More seriously, the quantity of the cut tobacco in the wind-power cut tobacco feeding is insufficient, the sufficient cut tobacco is difficult to provide for the subsequent production, and the integral normal work of the cigarette making machine is influenced.
For the blockage of the negative pressure filter screen, the conventional treatment mode is that once the insufficient amount of the cut tobacco is found in the production link, the cigarette making machine is closed firstly, then the cover plate of the cut tobacco collecting box is opened, the cut tobacco, foreign matters and the like attached to the surface of the negative pressure filter screen are cleaned manually, the cover plate of the cut tobacco collecting box is closed after the cleaning is finished, and the cigarette making machine is restarted to recover the production. If the negative pressure filter screen is seriously aged, shutdown cleaning operation is carried out for many times in the production process, and even the negative pressure filter screen has to be frequently replaced, so that the production efficiency is seriously influenced, and the labor and the equipment cost are greatly consumed.
