Description
Technical field
The utility model belongs to sewing machine technique field, is related to a kind of mounting structure of sewing machine throwing mechanism.
Background technology
Sewing machine is exactly the machine for being sutured sewing by suture, and sewing machine includes needle bar mechanism, Yarn taking-up mechanism, feeder
Structure, string-hooking mechanism and hold-down mechanism etc..Sewing machine includes flat seam machine, chain seam machine, overedger, flat seaming machine and lockstitch button holder etc..Flat-seam
Machine refers to the sewing machine for completing flat-seam sewing, and flat-seam sewing is cursor line, looper thread connects, interconnected certainly, interweaving forms various linear slits
Sewing.Type throwing mechanism is provided with flat seaming machine, bottom line is equipped with type throwing mechanism, type throwing mechanism is convex including being connected with rotating shaft
Wheel, cam often rotates carries out a routing once week to bottom line, completes a loose ends and take-up.General type throwing mechanism is arranged on bottom
In seat inner chamber, the both sides of type throwing mechanism are additionally provided with other mechanisms.Need to carry out clear line to type throwing mechanism when broken string occurs for bottom line
When threading again, because there is the interference of other mechanisms type throwing mechanism both sides, it will be wrapped in base disconnected on type throwing mechanism
Line, which is cleaned out and threaded again, becomes cumbersome.
Chinese patent literature data discloses the cam type throwing mechanism [application number for proposing a kind of flat seaming machine：
201120129995.3；Notification number：202047244U], including the throwing cam of annular groove, camshaft are formed with line crossing bracket and wheel face
By synchronous pulley and upper axle by synchronous band connection, pit is formed with the inside of head of sewing machine column, camshaft is stretched out of column
Go out pit, throwing cam is placed on camshaft external part admittedly, and the line crossing bracket bearing pin through line crossing bracket axle sleeve is parallel with cam and solid
It is right to cross line plate, the left top crossed line plate and be loaded on line crossing bracket due to pit, cross line piece and be loaded in line crossing bracket neck and snap onto routing
In the annular groove of cam, the right side of line crossing bracket is equipped with torsion spring, and torsion spring is stretched for the flexible gag lever post spacing to line crossing bracket out of column
Go out pit.Flexible gag lever post is made up of gag lever post and spring, and spacing pole spacing is in the translot of the bottom of line crossing bracket.
Above-mentioned cam type throwing mechanism is arranged in the pit of column, and operator's cleaning can be facilitated to be wrapped in type throwing mechanism
On broken string and thread again.But gag lever post is when being inserted in the translot of line crossing bracket, gag lever post by while spring pressure also
By the elastic force of torsion spring, at the same on column pit space it is limited, the structure of gag lever post and translot is not very big, will so be limited
Position bar is released very difficult from line crossing bracket.And must take out gag lever post out of translot in cleaning broken string and threading made line
Frame so causes type throwing mechanism cleaning broken string and threading to be inconvenient away from throwing cam.And sometimes broken string twines
Around it is too many need integrally to take out line crossing bracket pit and could clear up all broken strings, but because line crossing bracket pin on line crossing bracket
Axle and gag lever post are fixedly connected with column, and line crossing bracket bearing pin and gag lever post take out from column and be inconvenient, and cause to beat
Line mechanism cleaning broken string inconvenience.
The content of the invention
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, it is proposed that a kind of sewing machine throwing mechanism
Mounting structure, the technical problem of solution is how to make type throwing mechanism cleaning broken string convenient.
The purpose of this utility model can be realized by following technical proposal：
A kind of mounting structure of sewing machine throwing mechanism, including column, fluted, institute is opened up on the outer surface of the column
State and type throwing mechanism is fixed with groove, the type throwing mechanism includes the throwing cam and routing frame being correspondingly arranged, and the routing is convex
Wheel is connected on column, it is characterised in that seat board is removably fixedly connected with the column, the routing frame is be hinged present
On plate, when routing frame rotates around the pin joint of routing frame and seat board, the routing frame can separate with throwing cam, described
Flexible fixture is fixed with seat board, the routing frame can be fixed on seat board by fixture.
When routing frame is in operating position, the outer of throwing cam is embedded into routing frame；When routing frame is in threading
During position, throwing cam separates with routing frame.Routing frame around the pin joint of routing frame and seat board rotate, it becomes possible to make routing frame from
Operating position moves to thread position, just can return to operating position from thread position when rotating backward, reach the position of needs
