Sewing machine is to use one or more sewing thread, forms one or more stitching on sewing, so that one or more layers is stitched
The machine that material interweaves or unites by a seam.Fabric and leather, plastics, the paper such as sewing function sewing cotton, fiber crops, silk, hair, staple fibre
Deng product, the stitching neat appearance stitched out, smooth firmly, sewing velocity is fast, easy to use.With the development of sewing machine technique,
At present the species of sewing machine is very many, has the sewing machine of domestic, industrial sewing machine, computer controlled sewing machine.Current computer controlled sewing machine
Sewing mechanism generally includes left looper assembly, right looper assembly, and face realized by left looper assembly, right looper assembly cooperation stationary knife assembly
The sewing of material, but the right looper assembly stability in current sewing machine is poor, is susceptible to card line, leads to sewing thread to break,
Impact sewing machine normal work.
Utility model content
The right looper assembly stability of sewing machine in prior art is poor, lead to sewing thread to break in order to overcome for this utility model
Deficiency, there is provided a kind of good stability, can prevent sewing thread break sewing machine right looper modular construction.
To achieve these goals, this utility model adopts the following technical scheme that：
A kind of right looper modular construction of sewing machine, including shank, connecting seat, described connecting seat is provided with sliding sleeve, described
Sliding sleeve and connecting seat between rotate and be connected, described shank passes through sliding sleeve to be formed and is slidably connected, and the upper end of described shank is fixed
There is needle stand, the upper end of described needle stand extends and forms right looper, and the head of described right looper is provided with pin hole, the upper end side of described needle stand
Face extends and forms auricle, and auricle is provided with cable-through hole, and the lower end of described shank is provided with actuating arm, the outer end side surface of described actuating arm
It is provided with swinging axle, rotate between described actuating arm and shank and be connected, the side of described actuating arm is provided with V-shaped line hook, described V-shaped line
The lead that is respectively arranged at two ends with of hook is buckled.Sewing thread sequentially pass through lead buckle, cable-through hole, pin hole, swinging axle reciprocating rotation drive drive
Swing arm swings back and forth, thus driving shank to move back and forth in sliding sleeve, can occur between sliding sleeve and connecting seat to prevent from interfering
Rotate, the slip of shank, rotation control the motion track of right looper；When driving arm swing, energy handle buckled by line hook two ends lead
Line in spool pulls loose, and the sewing thread after pulling loose passes through right looper inlet wire, thus prevent right looper from directly entering bundle of lines line breaking, surely
Qualitative more preferable.
Preferably, the lower end of described actuating arm is provided with connecting hole, the lower end surface of actuating arm and the inwall of connecting hole it
Between be provided with regulation gap, the lower end side of described actuating arm is provided through adjusting the locking bolt in gap, described swinging axle with
Connect interporal lacuna cooperation.Swinging axle passes through connecting hole, then tightens locking bolt and makes the inwall of connecting hole clamp swinging axle, dress
Join, dismantle very convenient, easy access.
Preferably, the inwall of described sliding sleeve is provided with cannelure, the outside of described sliding sleeve is provided with and is connected with cannelure
Through hole, the outside of described through hole is provided with sealing-plug, is filled with graphite powder in described cannelure.In the surface of shank and cannelure
Graphite powder contact, lubrication, effectively reduce the frictional force between shank and sliding sleeve endoporus, reduce abrasion, adopt graphite simultaneously
Powder lubricates, and is not result on sewing thread to be stained with greasy dirt；Work as life-time service, graphite powder can open sealing-plug when minimizing, to
Filling graphite powder in through hole.
Therefore, this utility model has good stability, can prevent the beneficial effect that sewing thread breaks.
Brief description
