Portable minisize tobacco leaf filament cutter
(1) technical field
The utility model relates to a kind of miniature tobacco leaf filament cutter, belongs to tobacco cutting machine tool technical field.
(2) background technology
Good and bad and the employed scope of quality of tobacco will inhale to determine by product, and the pipe tobacco width is relevant with cigarette type and product design, and the uniformity coefficient of pipe tobacco width props up the suction flavor to cigarette again and produces certain influence; And on tobacco leaf base or research office and tobacco leaf meeting for the placement of orders, normally tobacco leaf is become pipe tobacco with scissor cut then and there, inhale and the tobacco leaf analysis for the people's product that come to order goods or make scientific researches; Since adopt manual scissor cut, not only time-consuming but also require great effort, and can't guarantee the pipe tobacco width requirement, and cause pipe tobacco width inequality easily, influence product and inhaled quality.
(3) summary of the invention
The utility model is at the deficiencies in the prior art, provide a kind of volume little, simple in structure, easy to operate, shear evenly and time saving and energy saving portable minisize tobacco leaf filament cutter.
The utility model is finished by following technical measures.
This filament cutter mainly is made up of chopping part and separate type fixed mount, wherein, the chopping part is by shredding knife, " U " shape holder, comb silk scraper, bearing, gear, charging aperture, thread-contacting disk, protective cover and flexible handle are formed, the axle head of two shredding knifes is assemblied on the riser of " U " shape holder by bearing, pair of engaged gears is installed in respectively on " U " shape holder right-hand member two chopping cutter shafts, flexible handle is connected with the shredding knife driving shaft by spline, comb silk scraper is positioned at two shredding knifes below, charging aperture and protective cover form one and are installed on " U " shape holder, and thread-contacting disk is placed on the base plate of " U " shape holder.
" U " shape holder is to be with trapezoidal swallow-tailed base plate to be formed by connecting by left and right two risers and.
The base plate of " U " shape holder forms movable the connection with the separate type fixed mount.
The separate type fixed mount is made up of support and connecting plate, and the connecting plate end face has and U " the trapezoidal dovetail groove that is complementary of shape holder base plate.
Described shredding knife is an axle cutter one, and local hollow, cutter tooth and cutter groove are matched in clearance.
Shredding knife length is 50mm~70mm.
Shredding knife facewidth degree and groove width are 0.75-1.2mm.
The two ends of described comb silk scraper are fixed in the vertical plates on both sides groove, and its cutter tooth inserts shredding knife trench bottom and adjustable height.
The utility model is fixed two shredding knifes and a comb silk scraper on it by " U " shape holder is set, and by being connected of pair of engaged gears and chopping cutter shaft, the formation transmission is had an effect; The base plate of " U " shape holder is arranged to have trapezoidal dovetail shaped to be convenient to flexibly connect with the separate type fixed mount, trapezoidal referring to, holder base plate and separate type fixed mount form axial cooperation, external port is greater than the inner end mouth, form a kind of trapezoidal angle, this structure plays axial location and locking effect, and the cooperation of trapezoidal dovetail mechanism has been played and two parts planes connected and the effect of axial location.The separate type fixed mount is set to be used for using in the place that workbench is arranged; During use, cooperatively interact, form a kind of fixed mechanism that dismounting is slidingly connected of being convenient to, adopt that this cooperating with compact stability property of connection is good, difficult drop-off, easy accessibility by the trapezoidal dovetail structure on the trapezoidal dovetail groove on it and " U " shape holder base plate.Shredding knife is set to a cutter one, and the part of axle is hollow, and the main shaft right-hand member is processed a cruciate flower keyway, is convenient to be connected with flexible handle; This structure saved being connected of axle and cutter, and the mutual play and the rolling that avoided spool, cutter are connected to form have alleviated weight, have reduced rigging error, have improved quality of fit.The width of cutter tooth is extremely important, and the machining accuracy error is 0.015mm, and the width of cutter tooth and machining accuracy are determining width dimensions and the error size after the pipe tobacco processing, and quality of fit is determining the shear effect of tobacco leaf between cutter tooth and the cutter groove; The facewidth that is provided with on the shredding knife equals groove width, and the mutual interlock of teeth groove of a pair of shredding knife in assembling back forms a kind of tighter matched in clearance, and reaches the purpose of shearing the certain width pipe tobacco.The setting of comb silk scraper (bamboo comb) is that the width according to the shredding knife groove processes, and its effect is to carry out combing to processing the back pipe tobacco, pipe tobacco is not sticked in the shredding knife groove, and the cutter trench bottom is cleaned out; During installation, a pair of comb silk scraper is positioned at two shredding knifes below, two ends are fixed in the vertical plates on both sides groove by jackscrew, and broach is evenly distributed in each cutter groove, and the broach front end contacts gently with bottom land, guarantees that bottom land pipe tobacco deposition is cleared up.About two groups of bearings that are provided with are inlayed respectively and fitted in two riser holes, form with the axle of two shredding knifes and to cooperate, support and also realize rotation.Pair of engaged gears is installed in respectively on the holder right-hand member two chopping cutter shafts, and gear is connected by flat key with axle; Crossing spline on the separate type flexible handle is connected with cruciate flower keyway on the shredding knife main shaft, and turning handle driven gear and shredding knife running during work realizes shearing function.The course of work: shake handle and drive a pair of gear, thereby a secondary shredding knife is rotated, the shredding knife of rotation is implemented to shear to the tobacco leaf that enters from charging aperture.By the comb silk scraper broach that is installed in each shredding knife groove finished pipe tobacco combing is got off, pipe tobacco is fallen into connect a box.According to the instructions for use of pipe tobacco width, adopt the shredding knife of different size to process.The pipe tobacco width range that processes can be between 0.75mm~1.2mm, and pipe tobacco specification error amount is ± 0.02mm.
The utlity model has rational in infrastructure, machining accuracy is high, dependable performance, volume is little, in light weight, be easy to carry, advantage such as simple to operate, time saving and energy saving.
