Abstract

The utility model relates to a twin shaft combined filament cutter which belongs to a device for processing long and thin strip-shaped articles. The utility model which is especially suitable for processing the articles of a kelp class. In order to reduce the manufacturing cost of the twin shaft combined filament cutter and extend the service life of the twin shaft combined filament cutter, the utility model provides a novel twin shaft combined filament cutter which is provided with a drive shaft, a driven shaft, a plurality of shock insulators, a plurality of cutters, fastening nuts and locking nuts. The utility model is characterized in that the drive shaft is provided with the cutters and the shock insulators; the circumference of each cutter is a thin disk provided with ratchets; the driven shaft is provided with a circular roller made of flexible material.

Description

Twin axle combination shredding knife

The utility model belongs to processing slim strip article device, is particularly useful for processing the tang article.

The patent that the inventor has obtained: the twin axle combination shredding knife (patent No.: be to be used for processing tang article device ZL99223716.5), this twin axle combination shredding knife is that a plurality of garden has ratchet on week cutting knife is being housed on the driving shaft, its width equals the tang strip item width that requires, the dottle pin littler than cutting knife diameter with the cutting knife same widths is housed again between two cutting knifes, cutting knife identical with driving shaft and dottle pin also are housed on driven shaft, it is the width of the cutting knife that axially staggers mutually of diaxon, and the mutual embedding people of the cutting knife on a diaxon part forms interlocking pattern.Transmission by driving gear and driven gear makes master and slave moving axis rotate relative to constant speed from the power of motor, from the tang article sent between the diaxon, will be cut into desired elongate strip by the cutting knife of band ratchet.This twin axle combination shredding knife has had very big progress than the whole shredding knife of twin axle; But also there is following shortcoming in it: at first, its manufacturing technique requirent is very high, because requiring two gaps between the cutting knife under the cutting knife interlocking pattern is between 0.01 millimeter and 0.003 millimeter, so the dimensional accuracy of cutting knife and dottle pin must be very high, the depth of parallelism at its two ends and two ends require also very strict to the perpendicularity of axle simultaneously, in case above-mentioned dimensional accuracy and position of related features surpass regulation, will produce excesssive gap between the cutting knife or produce interference and wear and tear, time one is long, the phenomenon of silk will appear can't cut, in addition because the processing technology of cutting knife and dottle pin is strict, their percent defective is also necessarily very high, so its manufacturing cost is also quite high, this twin axle combination shredding knife generally will be scrapped behind processing 10-20 ton tang article, and its life-span is lower.

In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model provides a kind of novel twin axle combination shredding knife, makes the dimensional accuracy of cutting knife and dottle pin and form and position tolerance reduce greatly, thereby reduces its manufacturing cost, and increase their service life.

The utility model twin axle combination shredding knife has driving shaft, driven shaft, dottle pin and cutting knife, clamp nut, locking nut is characterized in that: a plurality of cutting knifes and dottle pin are housed on the driving shaft, cutting knife is the garden has ratchet on week a thin dish, and the garden roller of being made by flexible material is housed on the driven shaft.The garden roller is to be made by nylon or plastics.

The advantage of the utility model twin axle combination shredding knife is as follows: because it just is equipped with cutting knife and dottle pin on driving shaft, and on driven shaft, only adorn the garden roller that a corresponding with it flexible material is made, one section degree of depth of cutting knife incision garden roller, so, shear mutually by two cutting knifes and cut off article and become cutting knife and shear mutually with the garden roller and cut off article.The dimensional accuracy that has just determined its cutting knife and dottle pin of this version itself and the requirement of form and position tolerance are very low, therefore, its percent defective are descended greatly, and its processing cost can be descended greatly; Simultaneously, also because the hardness of the garden roller that cutting knife and flexible material are made is mutually far short of what is expected, the garden roller is also mutually far short of what is expected with the hardness of cut material product, has lowered the wearing and tearing of cutting knife and garden roller greatly, so its life-span is also quite long.

Description of drawings is as follows: Fig. 1: assembling schematic diagram Fig. 2 of the utility model twin axle shredding knife: among the A part enlarged drawing figure among Fig. 1: 1, driving gear 2, driven gear 3, driving shaft 4, driven shaft 5, dottle pin 6, cutting knife 7, garden roller 8, clamp nut 9, locking nut 10, adjustment flange 11, sliding bearing 12, cage plate 13, adjustment screw 14, bracing piece 15, body 16, trimmer

Below in conjunction with accompanying drawing the utility model twin axle combination shredding knife is described in further detail: as shown in the figure: on the driving shaft 3 that key is housed, be separated by and be inserted in a plurality of dottle pins 5 and cutting knife 6, dottle pin and cutting knife are compressed by clamp nut 8 and locking nut 9; A garden roller 7 of being made by nylon is housed on the driven shaft 4 that key is housed, also compress with clamp nut 8 and locking nut 9, the thickness of adjusting flange 10 decides according to bracing piece 14, driving shaft 3 and driven shaft 4 usefulness bearing shells support, cage plate 12 is the boards that adopt for assembling twin axle combination shredding knife, cage plate 12 is contained on the body, and the degree of depth of cutting knife 6 incision garden rollers 7 is adjusted by trimmer 16 and housing screw 13.This twin axle combination shredding knife is that work is like this: the moment of torsion that is transmitted by the driving shaft left end rotates master and slave moving axis by driving gear 1 and driven gear 2, cuts out the tang article of delivering between cutting knife and the garden roller desired rectangular.
