Background
The slicing machine is a main device in a tobacco shred making line slicing and moisture regaining system of a cigarette processing enterprise and is also a first processing device in the tobacco shred making process, and the technical task of the slicing machine is to cut the tobacco bale with the external package removed into a plurality of blocks according to a certain thickness so as to provide technical conditions for loosening and moisture regaining of the tobacco blocks.
The inconsistent volume and width of the cut tobacco blocks of the slicing machine can cause unstable material flow of the discharging electronic belt scale, directly influence the loosening rate of loosening and moisture regaining and the stability of moisture and temperature of outlet materials, and cause the fluctuation of the processing moisture and temperature of the materials in the subsequent process, so that the electronic belt scale plays a vital role in the stability of the quality of the whole silk making process.
The traditional slicer mainly adopts the location mode of encoder + photoelectric tube, measures tobacco bale length and cuts the width, carries out the fixed length and cuts. The method is relatively extensive, and the thickness deviation of the cut tobacco bale is large. In the actual production process, part of the cigarette packets are special cigarette packets after the opening of the carton. The traditional slicing mode is adopted for the irregular cigarette packets, so that the deviation of tobacco flakes exceeds a standard value. Therefore, a new intelligent precise control mode must be developed to control the extremely poor width and volume deviation of the cut tobacco flakes and ensure that the volume or weight deviation of the tobacco flakes is within a control range. The temperature of the subsequent loosening and moisture regaining and the flow uniformity of the subsequent process section are ensured.
