Description
Technical field
The invention belongs to technical field of tobacco processing, in particular to a kind of based on the control of ramuscule cigarette pipe tobacco length
Screening plant.
Background technique
Ramuscule cigarette generally refers to the cigarette that Cigarette circumference design standard value is (17.0 ± 1.0) mm, with conventional cigarette phase
Than the character of ramuscule cigarette is varied widely.In recent years, China's ramuscule cigarette production and marketing increases substantially year after year, based on ramuscule cigarette
The product of body becomes the new kinetic energy of tobacco business development.The apparatus and process technology of ramuscule cigarette is primarily directed to cigarette packet in industry
Equipment improves, currently, there are cigarette substances and resistance to suction fluctuation in tobacco business ramuscule cigarette process, big, density of tobacco rod divides
Cloth is uneven, combustion cone falls the quality problems of the general character such as head is obvious, mainly since ramuscule cigarette tobacco structure is that cigarette physics refers to
Mark --- one of an important factor for stability, but tobacco structure is uneven in process, overlength silk and long filament for ramuscule cigarette
Winding, causes long filament rate higher, while ramuscule cigarette tobacco structure unevenly runs ramuscule cigarette comprehensive quality and equipment
Efficiency also has a significant impact, and therefore, prescinds equipment by adding reliable pipe tobacco sieve length after cut tobacco is dry, may be implemented soft
Property improve ramuscule cigarette tobacco structure distribution, promoted ramuscule cigarette comprehensive quality.
Pipe tobacco transporting equipment be largely turnover panel transport or conveyer belt transport, turnover panel transport will lead to a part of pipe tobacco
It is stuck in turnover panel, then falls in non-transmission region, cause the reduction of pipe tobacco conevying efficiency.Conveyer belt transport is due to pipe tobacco itself weight
Power reason can not be suitble to the transport of high angle.And above means of transportation can not achieve the screening of pipe tobacco, be unfavorable for improving
Tobacco structure.
One timing of chopping condition, the winding after long filament fold and cut tobacco are dry after chopping, leads to the irregular of pipe tobacco form,
It will affect Cheng Sihou tobacco structure.In general, the filament weight in ramuscule cigarette pipe tobacco accounts for about the 70%- of material total amount
75%, ratio shared by long filament is higher in pipe tobacco.On the other hand, long filament rate is higher, the poor cigarette to ramuscule cigarette of structural homogeneity
The influence of the quality index such as branch individual cigarette weight mark inclined, hardness, resistance to suction, end tobacco-falling quantity and cigarette making machine equipment operational efficiency is more next
It is more obvious.
By in ramuscule cigarette pipe tobacco overlength silk and long filament sift out and prescind, the demand of ramuscule cigarette can be better met.
Currently, lacking the ideal equipment sieved online for pipe tobacco in ramuscule cigarette process, existing screen(ing) machine is all based on routine
The screening of cigarette smoked sheet process, and there is the problems such as impermeable sieve, leakage sieve, plug-hole eye.
Summary of the invention
To solve the above problems, being passed the present invention provides a kind of screening plant based on the control of ramuscule cigarette pipe tobacco length
The property of can choose sieves pipe tobacco during defeated, realizes that the long filament in pipe tobacco is prescinded by flexible, selectivity, while reducing and transporting
Making in journey is broken.
To achieve the above object, technical scheme is as follows:
A kind of screening plant based on the control of ramuscule cigarette pipe tobacco length, including power source 1, transmission mechanism 2, power source 1
Output end and transmission mechanism 2 connect, and transmission mechanism 2 connects and the identical dynamic roller 3 in synchronous several intervals of driving；It is set on dynamic roller 3
It is equipped with along its axial alignment and what uniform intervals were arranged chooses knife 4, each choosing knife 4 includes multiple for stirring 41 Hes of blade of pipe tobacco
The fixed disk 42 being fixed on dynamic roller 3, blade 41 are uniformly distributed in fixed disk 42, each choose the angle phase of knife 4 during installation
Together, the position that knife 4 is chosen between adjacent dynamic roller 3 is staggered, and each blade 41 all extends to two neighboring on dynamic roller 3 adjacent thereto
In the gap that blade 41 is formed, intert staggered structure with the formation of blade 41 on adjacent dynamic roller 3；The both ends of blade 41 with it is adjacent
It is provided with identical spacing between dynamic roller 3, the rotation of knife 4 is chosen in the dynamic drive of roller 3.
In the technical program, further, the shape for choosing the blade 41 on knife 4 is isosceles trapezoid and bottom and fixed disk 42
Connection.
Further, blade 41 is an integral molding structure with fixed disk 42, and the middle part for fixing 42 is provided with mounting hole 43.
Further, the angle between the bevel edge and top margin of blade 41 is 105 °.
Further, the length of blade 41 is less than the length of setting screening pipe tobacco, and the length of blade 41 is on adjacent dynamic roller 3
Twice of 41 spacing of adjacent blades, the spacing between the both ends of blade 41 and adjacent dynamic roller 3 are 2-3mm.
Further, choosing knife 4 includes eight blades 41, and the length of blade 41 is 20-22mm, adjacent on same dynamic roller 3 to choose
The spacing of knife 4 is 25mm.
Further, it moves adjacent choose on roller 3 and is provided with axle sleeve between knife 4, axle sleeve will choose knife 4 and mutually compress and fix.
Further, the both ends for moving roller 3 are vertically installed with the fixed plate 5 being parallel to each other, and move roller 3 and connect with 5 activity of fixed plate
It connects.
Further, power source 1 is mounted in fixed plate 5, and power source 1 is motor 11.
Further, transmission mechanism 2 include be connected with motor 11 for adjustment speed retarder 21, be mounted on dynamic roller
The sprocket wheel 22 at 3 both ends, the chain 23 for connecting each sprocket wheel 22, chain 23 are connect with 21 power output end of retarder.
Beneficial effect
The present invention provides a kind of screening plant based on the control of ramuscule cigarette pipe tobacco length, will be in ramuscule cigarette pipe tobacco process
Long filament sieved.Interlaced with each other on adjacent dynamic roller, which chooses knife and consistently form during rotation, when use is sized
Gap can realize complete screening positioned at the pipe tobacco that knife is formed by conveyor surface is chosen according to the gap size of setting, avoid mesh
Mark pipe tobacco is fallen into below conveying device by gap.The sieve of pipe tobacco may be implemented in multiple dynamic rollers and the knife of choosing being mounted on dynamic roller
Choosing, transportation function, choose cutter shaft to gap can be used for length dynamic roller spacing adjacent less than two pipe tobacco screening, fall under dynamic roller
In the transport mechanism in portion；The pipe tobacco loose roll rotation that length is greater than two adjacent dynamic roller spacing moves to next dynamic roller, is finally sent into and divides
Cut machine.
Screening plant of the invention uses after cut tobacco is dry, and selectivity screening pipe tobacco is realized in pipe tobacco transmission process,
Long filament in pipe tobacco is prescinded for the long filament in pipe tobacco and is ready, improve the cigarette of ramuscule cigarette by after flexible, selectivity screening
The uniformity of silk structure, promotes the applicability of ramuscule cigarette pipe tobacco, and improves the comprehensive quality of ramuscule cigarette.
The present invention realizes the screening of pipe tobacco, transportation function with the knife of choosing being mounted on dynamic roller only with multiple dynamic rollers, chooses knife
Axial gap is adjustable, realizes that long filament finally can be sent into cutting machine by the regulation of flexible selectivity by pipe tobacco length.With biography
Vibration slot type sieve, through-hole type sieve and the fixed length chopping of system are compared, and the efficiency that long filament in pipe tobacco is sized can be improved, reduce simultaneously
Making in pipe tobacco process is broken.
