Description

Press-pull type sliding cut tobacco cutting device
Technical Field
The utility model relates to the field of cut tobacco cutting, in particular to a push-pull type sliding cut tobacco cutting device.
Background
The length of the tobacco shreds can not meet the technological requirements, and bamboo joint cigarettes can be caused in the cigarette rolling process, so that the quality of cigarettes is seriously affected.
The existing tobacco shred manufacturing equipment is mainly divided into the following three types, wherein the first type adopts a cutter plate of a shredder to cut the tobacco shred at fixed length, the second type adopts a rolling licker-in with speed difference and a cutter head to carry out rotary beating or rotary cutting, and the third type adopts a rotary moving cutter and a left fixed cutter to cut the tobacco shred. The fixed-length cutting mode of the cutter plate is to cut the filament, but the cutting length of the filament is shorter; in comparison, the device for rotary cutting by adopting the rolling cutter with speed difference and combining the movable cutter with the fixed cutter has more advantages.
1. The Chinese patent of the utility model is a cut tobacco and filament cutter for cigarettes, the publication date is 2015, 06 and 03, and a circular cutter with speed difference is adopted for rotary cutting. Although the tobacco shred equipment with the speed difference and the rolling cutter head for rotary beating or rotary cutting reduces the filament rate of tobacco shreds to a certain extent, the cutting mode is still pile-pressing shearing to the incoming material, and the two cutting edges cut the outward pile-pressing material from the root as the scissors are held by a hand, so that a lot of stuffy vehicles are accumulated. Specifically, when two opposite cutters are rotated relatively, one cutter is a high-speed cutter disc group, the other cutter is a low-speed cutter disc group, the cutters of the two cutter disc groups are corresponding, when the two cutter disc groups are moved relatively, the cutters of the two cutter disc groups are interacted and separated periodically to complete the shearing action, and when long cut tobacco falls between the two cutter disc groups, the high-speed cutter disc group tears the long cut tobacco and completes the cutting process. In the shearing process, the corresponding cutters form a shearing path for feeding from the beginning of contact to the mutual separation, and because the fast cutter head rotates at a linear speed of more than 1000 meters per minute, the generated positive pressure wind enables the tobacco shreds to rotate along with the cutter heads, the quantity and the moisture of the incoming materials of the tobacco shreds cannot be accurately controlled, and the cutting edges are worn, the tobacco shreds between the cutters are larger and cannot be immediately cut off, so that the tobacco shreds are pushed in the feeding direction or gradually accumulated between the two cutter heads along with the rotation of the cutter heads, and the tobacco shreds are blocked, cut off and blocked. In order to avoid the phenomenon, the cutter is forced to be more powerful by adopting a motor with higher power so as to enhance the passing performance of the cutter, but the method is undoubtedly not used for fundamentally solving the problems, and the tobacco shreds are crushed and increased, so that the energy consumption of the machine is increased.
2. The Chinese patent of the utility model, namely the low-energy-consumption cut tobacco shearing device for preventing cut tobacco from being broken, has the authorized date of 2018, 7 and 5, and is obviously energy-saving and reduces the broken rate of cut tobacco compared with cut tobacco equipment with a double-rolling cutter with a speed difference for rotary beating or rotary cutting. However, since the fixed cutter cutting edge is mounted parallel to the horizontal line of the center of the movable cutter, the rotary cutter cutting edge is manufactured parallel to the horizontal line of the center of the movable cutter in an inclined manner, so that the pressing cutting or the chopping cutting is formed. Because the fast cutter head rotates at a linear speed of more than 1000 meters per minute, the generated positive pressure wind enables the tobacco shreds to rotate along with the cutter head, and the cutter blade with the length of ten centimeters is only used for cutting the tobacco shreds by one to three centimeters, the cutting effect is good when the water content of the supplied materials is less, the material layer is thin and the cutting edge is sharp, and if the water content of the supplied materials is increased, the movable fixed cutter blade is sharpened and blunt or the tobacco shred thickness exceeds the distance between two fixed cutters, the tobacco shreds are accumulated on the joint of the root part of the fixed cutter and the bin wall, and the phenomenon that a cutter is easy to cut is easy to reach a 'stuffy car'.
In summary, the following problems in the prior art need to be solved in time: 1. the problems of high power consumption and stuffy turning and cutting caused by accumulation of the traditional cut tobacco during double-cutter rotary cutting and rotary pressing cutting of a cutter set matched with a movable cutter are solved; 2. the cutter head only rotates with the cutter head due to the high-speed rotation of the cutter head, and the cutter blade with the length of ten centimeters is only used for cutting the cut tobacco.

2. The rotary knife is in contact with the fixed knife by the root of the fixed knife and gradually inclines downwards, and the force generated by the rotary knife is utilized to drive the material to slide downwards along the inclined edge of the fixed knife, so that the movable knife head presses and pulls the cut tobacco to slide downwards along the fixed knife edge from the root of the fixed knife edge, the material is finally cut off, the shearing path of the material is prolonged, the problem of stuffy turning and cutting of the material caused by accumulation of the material is avoided, and the cutting time of the material is fully ensured.
3. The fixed cutter is obliquely arranged, namely the upper part of the fixed cutter root and the center of the movable cutter head form a horizontal line, the fixed cutter head part is obliquely inclined downwards by 20-40 degrees, when the cutting edge is not sharp and the thickness of the incoming material exceeds the distance between two fixed cutters, the movable cutter drags the material to slide along the fixed cutter edge after one cutter is cut, and the material is not accumulated to a 'stuffy car' under the same condition.
