Description
Technical field
The utility model relates to a kind of transmission system, relates in particular to a kind of embroidery machine list cam double link transmission system, for locking-type embroidery machine.
Background technology
The drive mechanism majority of locking-type embroidery machine is in the market single cam single-drive structure, because single-drive is the presser feet embroidery that moves up and down together with shank, when shank moves downward minimum point, presser feet has struck on fabric and needle plate, the embroidery machine of this kind of drive noise when embroidery is large, presser feet makes fabric displacement distortion while rubbing fabric, the style of embroidery is just meticulous not like this, and the style of the small letter of particularly embroidering and tatami lines is very unintelligible.People's living standard is more and more higher now, so requirement is also more and more higher, traditional single cam single-drive embroidery machine can not meet people's living needs.
Chinese patent 201220126340.5, crank-linkage type shuttle driving mechanism for a kind of embroidery machine is disclosed, comprise base and shuttle member and drive unit, base is a kind of tetragonal body case that is separated into interior case and outer container by gusset, wherein interior case extends a pair of linking arm, shuttle member is contained under this linking arm, its rotating shaft extends in outer container through interior case and gusset, drive unit comprises that being contained in rotating shaft extends drive pinion and the power transmission shaft vertical with rotating shaft and that mutually avoid on axle head, and it is outer by outer power drive that this end part of driving shaft extends interior case, also have the driving bevel gear on power transmission shaft and be contained in driving rod drive and the fan-shaped switch gear on gusset, driving rod drive comprises driven bevel pinion and output shaft and the crank connecting with it and connecting rod, connecting rod drives fan-shaped switch gear reciprocal switch in setting angle range, make itself and drive pinion engagement drive shuttle member.This structure is traditional structure, and the Product Precision of embroidering is out not high enough.
Utility model content
The utility model is mainly to solve the deficiencies in the prior art, while making shank drive block move downward minimum point, the position of embroidered fabric is just arrived in the downward motion of presser feet drive block, just can not produce the sound that presser feet drive block clashes into needle plate, greatly reduce like this noise of embroidery machine when embroidery, make embroidery pattern very meticulous, pattern is very clear very round and smooth beautiful, and embroidery effect is embroidery machine list cam double link transmission system very perfectly.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of embroidery machine list cam double link transmission system, comprise head shell, in described head shell, be provided with driving shaft, thread take-up cam, aluminum connecting rod and three shanks, the upper end of described driving shaft is provided with shank drive block, the lower end of described driving shaft is provided with presser feet drive block, between described three shanks and thread take-up cam, by eccentric cam, be fixedly connected, described aluminum connecting rod is fixedly connected by the left side of two, left side shank and shank drive block, described aluminum connecting rod is fixedly connected by two shanks of downside and presser feet drive block, three described shanks are fixedly connected by the right side of two, right side shank and shank drive block.
As preferably, left end and the head shell of three described shanks fix, and middle-end and the eccentric cam of three described shanks fix, and two shanks in the right-hand member of three described shanks and right side fix;
The left end of described aluminum connecting rod and head shell fix, and two shanks in the middle-end of described aluminum connecting rod and left side fix, and two shanks of the right-hand member of described aluminum connecting rod and downside fix.
As preferably, the right-hand member on described head shell top is provided with assembling breach, and the left-hand end of described head shell bottom is provided with inclination fitting surface.
Therefore, embroidery machine list cam double link transmission system of the present utility model, compact conformation, improves the fineness of embroidery, reduces and produces noise.
