Description

Be used to use the cutter sweep of the blade cuts bar of relative tilt
Technical field
The present invention relates to a kind of cutter sweep that is used for cutting rod.
The present invention can be used for helping automatic cigarette maker or packing machine, and following description is only for example with reference to these machinery.
Background technology
The automatic cigarette maker comprises the feed unit that is used to supply band, and every band is gummed and is used for filter tip is connected to the cigarette part of continuous tobacco rod; And bring and send the unit to comprise cutter sweep, described cutter sweep is used for laterally downcutting single band from the paper slip that spool unclamps.
The cigarette automatic packaging machine comprises the feed unit that is used to supply the packaging material thin slice, and every thin slice is folding around one group of cigarette; And packaging material thin slice feed unit comprises cutter sweep, and described cutter sweep is used for laterally downcutting single packaging material thin slice from the packing strips that spool unclamps.For example, at the packing machine that is used for the pack of production cigarette packets, packaging material thin slice feed unit provides paper tinsel system packaging material thin slice, and in the glassine paper machine, packaging material thin slice feed unit provides plastics heat sealing packaging material thin slice.
The feed unit cutter sweep of automatic cigarette maker or packing machine utilize usually two that face and counter-rotational roller carries out scissor cutting, be the cutting of point-to-point formula, a plurality of equidistant sharp-pointed blades of each roll support.Blade on roller blade on another roller relatively tilts with given angle, therefore the blade that cooperates on two rollers only skims over each other at the contact point place that moves gradually with roller turn, and when roller turn, the contact point place of bar between the blade of two cooperations that carries between two rollers cut gradually, to cut band.
The example of the cutter sweep of the above-mentioned type is open in U.S. Pat 4943341A1, and it discloses a kind of cutter sweep that is used to cut the filter tipped cigarette connecting band on the high-speed cutting filter assembly machine.Band downcuts from bar continuously by two counter-rotational rollers, and each roller has a plurality of equidistant blades; And each blade on the blade on the roller and another roller limits scissors tool, and described scissors tool is used for when roller turn at continuity point place cutting rod.
Owing to comprise two counter-rotational rollers, each roller has a plurality of blades, and the cutter sweep costliness and the volume of the above-mentioned type are big.In order to save cost and to reduce size, the someone proposes a kind of cutter sweep, comprises only roller that supports a plurality of equidistant rotating blades; With one with roller on the fixed blade of all rotating blades circulation cooperation.
Yet in the cutter sweep of the roller that comprises a fixed blade and a plurality of rotating blades of support, at the cutting run duration, the distance between the blade of each rotating blade and the blade of fixed blade does not keep constant.Or rather, the pivot center of the relative roller of each rotating blade tilts (necessary condition of scissor cutting) slightly, and the blade of rotating blade and the distance between the pivot center (being the radius of rotating blade blade) are along blade and non-constant.In order to eliminate this shortcoming, the someone propose to make fixed blade in intermediate deformation so that therefore the core of fixed blade more near roller, and compensates range difference between each rotating blade blade and the fixed blade blade.Fixed blade can be out of shape in the fabrication stage, but this solution makes the manufacturing of fixed blade complicated, the most important thing is, made the extremely difficult sharpening of the fixed blade that has non-vertical cut cutter sword.Selectively, fixed blade can be at assembling stage by being fixed the screw distortion of blade.Yet, because the high flexible rigidity of fixed blade, so this solution is the machinery complexity, and the correction of stipulating the rough repetition test that is difficult to calibrate.
The influence that reduces the variable in distance between the blade of the blade of each rotating blade and fixed blade requires inclination angle very little between each rotating blade and fixed blade (for example less than 0.5 °).On the other hand, have the sizable power of scissor split requirement at very little inclination angle, this is cost with the cutting accuracy.
At last, the cutter sweep of the above-mentioned type needs conscientiously maintenance (especially in the downtime), because in order to ensure high-quality (being straight clean) cutting, it is very sharp-pointed that blade must keep, and therefore must regularly fine away, in a single day this means and remove and ressemble blade, and ressemble, will accurately regulate blade position.In addition, in each sharpening process, wear and tear and shortened blade, therefore must the replacement blade given repeatedly sharpening process after.
Summary of the invention
The purpose of this invention is to provide a kind of cutter sweep that is used for cutting rod, be designed to eliminate above-mentioned shortcoming, and cheaply but also easily produce simultaneously not only.
According to the present invention, a kind of cutter sweep that is used for cutting rod (strip) is provided, cutter sweep comprises: around the roller of rotary middle spindle rotation; At least one removable blade, described removable blade is coupled on the roller, and tilts with first inclination angle with respect to rotating shaft; Be located adjacent to fixed blade in the fixed position of roller with at least one, described fixed blade is by skimming over or nuzzle up, and the removable blade cooperation is given the band that send to cut the cutting of (cutter) formula step by step between two blades; Cutter sweep is characterised in that: fixed blade tilts with second inclination angle with respect to rotating shaft, and second inclination angle equals first inclination angle and relative with first inclination angle, thereby relatively tilts with respect to removable blade.

In the preferred embodiment, removable blade 5 and fixed blade 6 all comprise two cuttves (knives) 8, described cutter 8 is arranged in " V " shape to produce dual scissor cutting symmetry, simultaneously, therefore obtain two " V " shape blades 5 and 6 (obviously, because the relative tilt angle of single cutter 8, a V puts upside down with respect to another V, and therefore a V is recessed, and another is protruding).Cutter 8 preferred arrangement of removable blade 5 and fixed blade 6 become " V " shape so that dual scissor cutting symmetrical to the center generation from the outward flange of bar 2, simultaneously, and this batten 2 tear the core that appears at bar 2 arbitrarily, and core be can't see in finished product usually.In the optional embodiment that does not show, each all comprises a cutter 8 removable blade 5 and fixed blade 6.
Two cuttves 8 of removable blade 5 and fixed blade 6 preferably are arranged side by side, but do not link to each other each other, so the position of each cutter 8 can be independent of the position adjustment of another cutter 8, to obtain the more cutting of good quality.
In a preferred embodiment, each cutter 8 adopts the form of rectangular prism, has the parallelogram bottom, 9, two secondary relatively sidewalls 10 perpendicular to major side wall 9 of two opposite major sides walls; With four vertical blades (edge) 11, each bar is sharpened to limit the cutting edge of cutter 8, and described vertical blade 11 is limited between the major side wall 9 and secondary sidewall 10 of each cutter 8.
Each cutter 8 is preferably about at least one central axis symmetry, so that have at least two interchangeable cutting edges.More clearly, each cutter 8 is about two vertical centre axis symmetries, thereby has four interchangeable cutting edges, so each cutter 8 is before fining away or changing, and can use four times with four cutting edge work that utilize it by rotating four times.
For each cutter 8 of removable blade 5, roller 3 comprises the bearing 12 with the flat stayed surface 13 that is parallel to rotary middle spindle 4, and the major side wall 9 of each cutter 8 of removable blade 5 leans against on the stayed surface 13.At least one trip bolt 14 is set remains on the stayed surface 13 with each cutter 8 with removable blade 5, the through hole 15 that passes in the cutter 8 inserts, and is screwed in the roller 3.The internal diameter in each hole 15 is greater than the external diameter of trip bolt 14, to allow to adjust the position of removable blade 5.
Bearing 12 also comprises across rotary middle spindle 4 and perpendicular to the flat stayed surface 16 of stayed surface 13, and the secondary sidewall 10 of each cutter 8 of removable blade 5 leans against on the stayed surface 16.At least one adjustment screw 17 is passed hole 18 and is screwed into and passes stayed surface 16, and compresses the cutter 8 of removable blade 5, and moving forward cutter 8, thereby the position of cutter 8 is regulated in the position of relative fixed blade 6.For each cutter 8 two adjustment screw 17 are set preferably.
For each cutter 8 of fixed blade 6, cutter sweep 1 comprises the bearing 19 of the bearing 12 that is similar to each cutter 8 that is used for removable blade 5.More clearly, with at least one trip bolt 14 each cutter 8 of fixed blade 6 is coupled to its bearing 19, and may uses the anchor clamps (not shown), described anchor clamps are moved cutter 8 on the stayed surface (therefore it also limit reference surface) of bearing 19 diagonally.
In the preferred embodiment, each cutter 8 of removable blade 5 comprises that near secondary sidewall 10 vertically weakening element separately increases the vertically flexible of cutter with the part.More clearly, each weakens element and is limited by the grooves 20 that are parallel to vertical limit 11 and be formed in the major side wall 9, and is used for locally increasing the vertically flexible of cutter 8, so that cutter 8 can bendings and can not fracture when closure.
