Description
Technical field
The invention belongs to technical field of sewing equipment, it is related to a kind of routing loose ends structure of sewing machine.
Background technology
Existing many sewing machines can set automatic shearing mechanism, when sewing machine carries out automatic shearing, in order to ensure to stitch
Line can successfully be cut, and prevent off-line when sewing machine plays seam again, generally require progress loose ends routing while trimming.
It at the end of sewing, sews cloth to easily take out, sewing machine needs to act with presser foot lifter loose ends.But currently on the market
Sewing machine with automatic shearing function has loose ends function in trimming, and does not have loose ends function in presser foot lifter.Traditional is general
Logical sewing machine only has the function of loose ends due to being not provided with automatic shearing mechanism in presser foot lifter.It is existing to carry automatic shearing
The routing loose ends mode of the sewing machine of function is that action is transferred to thread tension releasing lever rod by trimming driving source, then drives loose ends bent again
Handle acts, and then moves downward thread tension releasing disc, completes loose ends, while routing bar and routing is driven to hook and complete routing action.
China's patent application document (publication number：CN105420945A；Publication date：2016-03-23) one kind is disclosed to be used for
Double thread releasing mechanisms of sewing machine, this pair of thread releasing mechanism include trimming thread releasing mechanism and presser foot lifter thread releasing mechanism, wherein：Trimming loose ends
Mechanism includes trimming steel wire rope, the trimming loose ends connecting plate for being connected to trimming steel wire rope and the hinged pine of trimming loose ends connecting plate
Line crank, the pin fixed to loose ends crank and the thread tension releasing disc to cooperate with the pin, one end of loose ends crank are rotationally pacified
It being attached on casing and its other end is hinged on tube socket, tube socket includes through hole, and routing bar is fixedly connected in the through hole of tube socket,
Thread tension releasing disc is movably attached on casing and for two thread tension discs of clamp device assembly to be separated；Presser foot lifter thread releasing mechanism includes lift
Presser feet steel wire rope and thread tension releasing disc, presser foot lifter steel wire rope are connected to thread tension releasing disc, in presser foot lifter loose ends, pull presser foot lifter steel wire
Rope, presser foot lifter steel wire rope pull thread tension releasing disc movement, therefore thread tension releasing disc acts on two thread tension discs of clamp device assembly and makes it
Separate, so as to which the suture being clipped between the two thread tension discs is released.
Existing sewing machine throwing thread releasing mechanism is in the prevalence of the defects of complicated, number of parts is more, installation trouble.
Double thread releasing mechanisms in above patent document are carried out using cord pulling type structure, and by trimming driving source and presser foot lifter driving source
Driving, then the tightening of steel wire rope and release are driven by a series of driving parts, the action of routing loose ends, installation could be completed
It is very cumbersome, and steel wire rope can increase larger resistance in the case where turn is more, and appearance action delay, stuck etc. are existing
As.
The content of the invention
The present invention provides a kind of routing loose ends structure of sewing machine, this hair for the above problem existing for existing technology
It is bright the technical problem to be solved is that：The stability in use and reliability for how improving sewing machine doubles line loose ends structure subtract simultaneously
Few amount of parts.
The purpose of the present invention can be realized by following technical proposal：
A kind of routing loose ends structure of sewing machine, sewing machine include casing and clamp device assembly, the routing loose ends structure
Have including supporting rack and the thread tension releasing disc being arranged on support frame as described above, on the thread tension releasing disc corresponding with the clamp device assembly
Loose ends lug, the thread tension releasing disc can move on support frame as described above and so that the loose ends lug struts the tension disk group
The intermediate plate of part, which is characterized in that loose ends crank is connected with by axial screw on the casing, the casing is equipped with two-way drive
Moving part, has the drive rod for being capable of way moving on the bi-directional drive part, and support frame as described above is equipped with routing frame and described beats
Routing corresponding with the clamp device assembly is installed on coil holder to hook；One end of the loose ends crank and the one of the drive rod
End is in contact, and the other end of the loose ends crank is connected with the routing frame；Also having on the loose ends crank can drive
The impeller of the thread tension releasing disc movement；The other end of the drive rod and the thread tension releasing disc lean and can promote the loose ends
Plate moves.
Its principle is as follows：Clamp device assembly is mounted on by screw on supporting rack, and supporting rack is mounted on casing, every group of folder
Line device component includes at least two intermediate plates, and two intermediate plates are become by spring or the effect of other elastic components with the movement mutually to recline
Gesture, suture are passed through between two intermediate plates, so that two intermediate plates of every group of clamp device assembly clamp suture；Loose ends crank
Medium position be connected on axial screw, loose ends crank can be swung around axial screw；During original state, the drive of bi-directional drive part
Lever is centrally located, and during trimming, bi-directional drive part acts so that drive rod is towards the side that can promote loose ends crank-swinging
To movement, simultaneously thread tension releasing disc and routing frame is promoted to move after loose ends crank-swinging, the loose ends lug on thread tension releasing disc is towards corresponding
It is moved in clamp device assembly, struts the intermediate plate of clamp device assembly, achieve the purpose that loose ends；After the movement of routing frame routing is driven to hook to move
Dynamic lower suture, achievees the purpose that routing loose ends；When presser foot lifter, it is only necessary to which loose ends acts, at this point, the driving of bi-directional drive part
Bar moves backward, and by the drive rod other end thread tension releasing disc is driven to move, and drive rod cannot drive routing frame to move at this time, so as to only
Only realize loose ends action.Routing loose ends structure in the technical program can be realized does not sympathize in two kinds of trimming and lifting presser feet
Double loose ends functions under shape, while reduce the connection between trimming driving source and presser foot lifter driving source and routing loose ends structure
Part completes double loose ends functions of routing loose ends by a bi-directional drive part, and installation is simple, and work is more reliable and more stable,
Reduce occur in transmission process interim card, it is stuck the problems such as.
Institute can be made by being equipped in the routing loose ends structure of above-mentioned sewing machine, between support frame as described above and the thread tension releasing disc
The resetting spring of loose ends sheet reset is stated, the torsional spring that can reset loose ends crank is arranged on the axial screw.It is specifically, multiple
