Fig. 1-Fig. 3 is please referred to, Fig. 1 provides the upper head system of sewing machine by a kind of specific embodiment of the utility model
Overall structure diagram；Fig. 2 is the right view stereoscopic schematic diagram of head connection component in Fig. 1；Fig. 3 is head connection group in Fig. 1
The left view stereoscopic schematic diagram of part.
In a specific embodiment, the upper head system of sewing machine provided by the utility model includes on the whole
Head connection component 1 and head 2, the other structures of certain sewing machine are since, without direct correlation, this is practical new with the utility model
Type no longer refers to.
Head 2 is main equipment, it is mounted by head connection component 1.
Head connection component 1 realizes the mounting with casing by fuselage mounting plate 61, therefore fuselage mounting plate 61 carries
All multi-parts.
Motor 11 is installed on fuselage mounting plate 61, motor 11 can be rotating electric machine, can also with hydraulic motor etc. its
His power part.Motor 11 is vertically arranged, i.e., its output shaft is vertically arranged.Certainly, it is so-called it is vertically arranged be and laterally set
Opposite concept is set, some special value should be utterly defined in by being not meant as its vertical angle.
The output shaft of motor 11 is also equipped with pinion gear 14, so as to drive pinion gear 14 to rotate.Pinion gear 14 and branch
Pinion shaft 16 can be set between seat 41.
Support 41 is also equipped on fuselage mounting plate 61, support 41 can be relative to fuselage mounting plate 61 in vertical direction
Upper opposite sliding, can also be fixedly installed relative to fuselage mounting plate 61.
The basic function of support 41 be support dependency structure, though therefore need not be strict with, it generally answers level to set
It sets, and therefore the substantially vertical setting of fuselage mounting plate 61 considers for reasonable integral structure, can be arranged therebetween
The side of left side bracket 42 and right side bracket 44, left side bracket 42 and right side bracket 44 respectively with the left and right two of fuselage mounting plate 61
The bottom edge of side connection, left side bracket 42 and right side bracket 44 is respectively fixedly connected with the left and right sides of support 41.
Head 2 is carried by support 41, and can be rotated relative to support 41；The periphery of head 2 is further set with
The gear wheel 33 of synchronous rotation, gear wheel 33 are engaged with pinion gear 14.
Linear guide 51, sliding block 52, bracket mounting base 53, elevating lever 24, cylinder 21, cylinder mounting plate 22, floating in figure
The setting of the components such as connector 23 is for the vertical opposite sliding for realizing support 41 relative to fuselage mounting plate 61；Such as preceding institute
It states, when the two does not need opposite slide, above-mentioned associated components is cancelled.
If the pinion gear 14 in the utility model is set as long tooth face gear, it is rationally set in conjunction with specifically used occasion
Length and position range can then make in lifting travel gear wheel 33 be always maintained at the shape being meshed with pinion gear 14
State.
Sewing machine provided by the utility model, head can be rotated relative to support driven by a moto,
Therefore can when sewing backstitches direction rotating head component, make the mutual alignment of eedle and suture be always held at along seam when
State improves the quality of sewing so as to avoid backward stitch is generated.
Furthermore, it is possible to do some other improvement to sewing machine provided by the utility model.
For example, the output shaft of rotating electric machine can directly be connect with pinion gear 14, retarder 12 and connection can also be passed through
