Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Core of the present invention is to provide a kind of sewing machine, and quality of not only sewing is obviously improved, and the structure letter of equipment
List, specification is small, use cost is low.
Fig. 1-Fig. 3 is please referred to, Fig. 1 is whole for a kind of upper head system of the provided sewing machine of specific embodiment of the present invention
Body structural schematic diagram；Fig. 2 is the right view stereoscopic schematic diagram of head connection component in Fig. 1；Fig. 3 is head connection component in Fig. 1
Left view stereoscopic schematic diagram.
In a specific embodiment, the upper head system of sewing machine provided by the present invention includes head on the whole
Connection component 1 and head 2, the other structures of certain sewing machine are since, without direct correlation, the present invention no longer refers to the present invention.
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 present invention is set as long tooth face gear, its length is rationally set in conjunction with specifically used occasion
And position range, then gear wheel 33 can be made to be always maintained at the state being meshed with pinion gear 14 in lifting travel.
Sewing machine provided by the present invention, 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 shape
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 present invention.
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
Axis device 13 is connect with pinion gear 14.Retarder 12 may be mounted on retarder support 15.
Referring to FIG. 4, Fig. 4 is the schematic cross-sectional view of Fig. 1 bottom bracket axle mounting means.
As previously mentioned, head 2 is carried by support 41, and can be rotated relative to support 41.It can be by with lower section
The connection of formula realization head 2 and support 41.
The rotation set 34 being rotatablely connected with support 41 is set, and head 2 is mounted on rotation set 34 by the setting of 34 general vertical of rotation set
Gear wheel 33 is fixedly mounted on the top peripheral of rotation set 34 by bottom.
Support flange 45 can also be fixedly mounted in support 41, so that rotation set 34 be made to rotate by bearing 46 and support flange 45
Connection, and then realize rotation connection of the rotation set 34 relative to support 41.
Head connecting flange 35 can be set in the bottom of rotation set 34, and head 2 can pass through head connecting flange 35 and rotation set
34 are fixedly connected.
The top of rotation set 34 can also install slip ring 31, specifically, rotation set 34 can be fixedly connected with slip-ring rotor 311,
Slip-ring rotor 311 and rotation set 34 are coaxially disposed；The top of slip-ring rotor 311 is further rotatably connected to same coaxially setting
Slip ring stator 312.
Slip ring stator 312 is fixedly connected by slip ring check plate 43 with left side bracket 42 or right side bracket 44, certainly
Can be with both and meanwhile be fixedly connected；So as to improve the operation stability of equipment.
The setting of the above rotation set 34 and its related accessory, the rotary course of head 2 can be made by simple structure
It is more reliable and stable.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
The upper head system of sewing machine provided by the present invention is described in detail above.It is used herein specifically
Principle and implementation of the present invention are described for a example, the present invention that the above embodiments are only used to help understand
Method and its core concept.It should be pointed out that for those skilled in the art, not departing from original of the invention
, can be with several improvements and modifications are made to the present invention under the premise of reason, these improvement and modification also fall into right of the present invention and want
In the protection scope asked.
