The fixture disclosed by the utility model is simple in structure and convenient to operate, the positioning accuracy during measurement can be ensured, a frequently-used adjustment size is considered at the same time, and replacement and adjustment of frequently-used filter rods of a variety of specifications within 120mm can be met.

Description

A kind of spicing machine filter stick cutting knife is adjusted frock

Technical field

The utility model relates to a kind of spicing machine filter stick cutting knife and adjusts frock.

Background technology

The modular device that the filter stick cutting knife of PASSIM spicing machine is mainly comprised of knife rest, shaft coupling, guide rail, cutting edge, slitter shaft and gear etc.Filter stick cutter motor inputs to travelling gear by synchronous cog belt and shaft coupling by power, makes two cutting knife constant speed rotations cut off filter stick, and filter stick is divided and is cut to isometric two sections or three sections.Left and right rail can be adjusted according to the length of filter stick, and edge of a knife blade tip stretches out the bipassage ring that filter stick cylindrical inserts respectively hopper drum and describes in cutter groove, should first guarantee that two cutter are in the appearance cutter groove center position of hopper drum when mounting tool post.

In transmitting cutting process, hopper drum carries filter stick and turns clockwise, and by guide rail, the relative cutting knife in filter stick length center is proofreaied and correct.Existence due to the thickness of cutting knife own, when filter stick slitting, certainly will produce to the trend of two end movements, to cause like this filter stick both ends impaired, for preventing that filter stick is because of axially loaded bending, at the corresponding cutting position of interior follower rail, be processed with groove, make the filter stick after cutting have while moving axially certain gap to exist.When filter stick is cut, two cuttves act on same filter stick when different, in order to avoid make filter stick produce excessive cutting force, rotate.

When changing cigarette specification, need corresponding adjustment cutter location, and the thickness that the width dimensions that holds cutter groove is 0.4mm, blade is 0.25mm, placed in the middle in holding cutter groove in order to guarantee blade, it is therefore relatively high that required precision is adjusted in the position of cutting knife, otherwise blade is interfered with appearance cutter groove, easily causes and forges a knife; Because the medial support bearing of cutter shaft is high-speed bearing, so this bearing easily weares and teares, and now needs to change and the position dimension of positioning blade again; When allowing blade replacement more, if card rust occurs for high-speed bearing and cutter shaft, while impacting cutter shaft, the position of bearing is moved, and then causes that the cut point of blade is offset, and now needs again to proofread and correct the position of blade.

When adjusting blade position, conventional method is: utilize the spacing of vernier caliper measurement guide rail spacing and blade and guide rail to position adjustment, in operating process, cannot guarantee that slide calliper rule are completely parallel with cutter shaft, therefore inevitably can bring measure error, and the position accuracy demand of blade is higher, so in actual adjustment process, need to repeatedly carry out Installation Validation and dismounting adjustment, not only increased the amount of labour, and improved maintenance cost, cause maintenance efficiency lower, affect normal production operation.

Utility model content

The utility model provides a kind of spicing machine filter stick cutting knife to adjust frock, for reliablely and stablely locating cutter location, guarantees that precision is adjusted in the position of cutting knife.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of spicing machine filter stick cutting knife is adjusted frock, comprises axle, cover and jackscrew, and cover can endwisely slip and be locked on the target location on axle by jackscrew along axle; The two ends of axle are provided with cylinder boss, and boss spacing is 120mm, are provided with the graduation mark at 5mm interval on axle.

The downside of cylinder boss is provided with plane ladder.

The inner circle of cover and the excircle dimension of axle are suitable, and the width of cover is 10mm, on the center width position of cover, are provided with a hole.

The silk hole of jackscrew thread size and cover is suitable, and jackscrew adopts annular knurl jackscrew.

The utility model, because one end of axle is designed with datum level, therefore can reliably be located; And can measure target range by the end face of cover, and simple and reliable while adopting this frock to carry out filter stick cutting knife adjusted size, can effectively guarantee the positioning precision measured, thereby improve maintenance efficiency, guarantee repair quality.

Compared with prior art, the utility model has the advantages that: simple in structure, easy to operate, the positioning precision in the time of can guaranteeing to measure, takes into account conventional adjustment size simultaneously, meet 120mm with the replacing adjustment of interior conventional multiple filter stick specification.

The specific embodiment

Embodiment: as Figure 1-3, a kind of spicing machine filter stick cutting knife is adjusted frock, comprises axle 2, overlaps 1 and jackscrew 3, and overlapping 1 can endwisely slip and be locked on the target location on axle by jackscrew 3 along axle 2; The two ends of axle 2 are provided with cylinder boss, and boss spacing is 120mm, are provided with the graduation mark at 5mm interval on axle 2.The downside of cylinder boss is provided with plane ladder.Cover 1 inner circle is suitable with the excircle dimension of axle 2, and overlapping 2 width is 10mm, is provided with a hole overlapping on 1 center width position.Jackscrew thread size is suitable with the silk hole of cover 1, and jackscrew 3 adopts annular knurl jackscrew.

Cover 1 endwisely slips and is locked on axle 2 by jackscrew 3 along axle 2.Measure while adjusting, the left side first step of axle 2 is placed in the upper end cambered surface of outer guide 4, the right side of axle 2 is arranged on interior guide rail 5 by bearing 8, the inner side convex surface laminating of the measurement datum of axle 2 and outer guide 4, movable sleeving 1 is to corresponding scale size and by jackscrew 3 lockings, and mobile cutter shaft 6 makes the corresponding end face laminating of end face with the cover 1 of cutting knife 7 to correct position.

The base plane of axle 2 is used for hiding blade, occurs mutually to interfere while avoiding measuring, and impact is normally measured; The datum level place, left side of axle 2 is provided with boss, for location survey benchmark, guarantees the perpendicularity of datum level, and axle 2 is paralleled with cutter shaft 6, guarantees certainty of measurement; The 5mm interval graduation mark of axle 2 is for observing the conventional size distance value in location: 40mm, 50mm, 80mm, 100mm, 120mm etc. meet the distance measurement demand of guide rail spacing and blade and guide rail simultaneously.
