Description
【Technical field】
The present invention relates to the shank component and machine head of embroidery machine of a kind of embroidery machine, belong to embroidery machine accessory field.
【Background technology】
With the development of science and technology computerized emboridering machine has become the main mechanical of embroidery industry, and in embroidery machine most
For part and parcel is the head section of embroidery machine.
Machine head of embroidery machine, substantially including needle bar frame, shank, presser feet, shank and presser feet can make longitudinal direction relative to needle bar frame
Linear reciprocating motion, the whole movement travel of shank is broadly divided into first decline stage, sewing stage, complete return stage.
And in traditional machine head of embroidery machine, in these stages, what shank and presser feet were typically moved together, especially sew the stage
Interior, shank drives presser feet to decline to compress cloth cover when declining, and drives presser feet to be gone up during shank rise simultaneously, and sews
Stage is often the high speed reciprocating stage of shank.The drawbacks of this is caused to traditional machine head of embroidery machine is that shank is in seam
Thread course movement when to attach feet motion, so as to cause the load force of shank excessive, limit shank reciprocating motion speed
Degree, so as to limit the operating efficiency of machine head of embroidery machine.
【The content of the invention】
The technical problems to be solved by the invention are to overcome the deficiencies in the prior art and provide a kind of shank of embroidery machine
Component and machine head of embroidery machine, can effectively reduce the load force of shank, improve the operating efficiency of machine head of embroidery machine.
Above-mentioned technical problem is solved, the present invention is adopted the following technical scheme that：
A kind of shank component of embroidery machine, including shank and presser feet, the shank are provided with pin folder, and the presser feet includes the body of rod
And pressing plate, the body of rod is pushed to drive presser feet to decline during the shank decline, the rise of presser feet is mutually only with the rise of shank
Vertical operation, the shank component also includes restorer, and presser feet is driven by the restorer, within the sewing stage, the pressure
The avoidance gap for preventing presser feet from load is produced to shank is formed between plate and pin folder.
Using beneficial effects of the present invention：In traditional machine head of embroidery machine, the motion of shank and presser feet is all linkage, no
It is separated from each other, shank descent tape dynamic pressure underfooting drop, shank gos up and drives presser feet to go up, so, in order to reduce the load of shank, reason
By above the reciprocating motion of shank and the reciprocating motion of presser feet should be realized to be separated from each other, i.e. the reciprocating motion of shank and presser feet
Move back and forth separate operation, it is mutually non-interference, so both motion when, suffered load is also separate, so sets
After meter, shank undertakes the loads of presser feet in motion without whole, so as to effectively reduce load suffered when shank is moved,
On the premise of same driving force, it is ensured that the movement velocity of shank faster, so as to allow machine head of embroidery machine within the unit interval
Lower pin number of times it is more, substantially increase the operating efficiency of machine head of embroidery machine.But if shank and presser feet are completely independent operation,
Then need two sets of drive systems to drive, can so increase part, increase the volume of machine head of embroidery machine, also accordingly increased embroidery
The cost of machine head.
Shank and presser feet are not completely independent in actual motion in the present invention, there is also the relation of linkage, and the linkage is closed
Owner will be during shank decline, and shank can drive presser feet to decline during decline, realizes the effect of linkage, and is returning
During rising, shank is gone up by the needle bar driver in machine head of embroidery machine, and presser feet is then by answering in presser feet
Position device is gone up, so both shank and presser feet are the independent operatings during rise.
So design, for driving the needle bar driver of shank, needle bar driver only needs to be supplied to shank to drive
Power, it is not necessary to undertake the driving force of reset presser feet, i.e., for traditional embroidery machine, only assume responsibility for the load of part；
For the restorer of presser feet, it is only necessary to the active force for being supplied to presser feet to reset, without to presser feet

Embodiment 1
As shown in Figures 1 to 4, it is machine head of embroidery machine in the present embodiment, it includes needle bar frame 1, and needle bar frame 1 is provided with shank
Component, shank component includes shank 10, presser feet 2, and the bottom of shank 10 is provided with pin folder 103, and presser feet 2 includes pressing plate 20, the body of rod 21
And restorer, restorer is preferably back-moving spring 22 in the present embodiment, and pin folder 103 and pressing plate 20, can not shown in Fig. 1 to 4
Referring in Fig. 5, shank 10 and presser feet 2 can be reciprocating relative to needle bar frame 1, and machine head of embroidery machine also includes driving in addition
Case 30 and the needle bar driver being located in driving box 30, needle bar driver include the first cam 31, and the first cam 31 is in the first electricity
Realize rotating under the driving of machine, so as to drive shank 10 to make straight reciprocating motion, the first motor not shown in Fig. 1 to 3, it is necessary to
Illustrate, in Fig. 1 to Fig. 3, in order to simplify expression, a shank 10 and a set of presser feet 2 are only illustrated on needle bar frame 1, it is real
In the product of border, laid out in parallel has some bar shanks 10 and some set presser feets 2 on needle bar frame 1.
In traditional machine head of embroidery machine, the motion of shank 10 and presser feet 2 is all linkage, is not separated from each other, in sewing rank
Section is also that in this way, the descent tape dynamic pressure pin 2 of shank 10 declines, shank 10 gos up and drives presser feet 2 to go up.So, in order to reduce shank
10 load, should realize the reciprocating motion of the linear reciprocation of shank 10 and presser feet 2 being separated from each other in theory, i.e. shank 10
Move back and forth with the separate operation of reciprocating motion of presser feet 2, it is mutually non-interference, both so when moving, suffered load
Also separate, after so designing, needle bar driver undertakes the loads of presser feet 2 when driving shank 10 in motion without whole,
So as to effectively reduce load suffered when shank 10 is moved, on the premise of same driving force, it is ensured that shank 10
Movement velocity faster, so as to make lower pin number of times of the machine head of embroidery machine within the unit interval more, substantially increases machine head of embroidery machine
Operating efficiency.If but the component of shank 10 and presser feet 2 are completely independent operation, needing two sets of drive systems to drive, this
Sample can cause that part increases in driving box 30, increase the volume of machine head of embroidery machine, also accordingly increased the cost of machine head of embroidery machine.
And shank 10 and presser feet 2 are not completely independent in actual motion in the present embodiment, the relation of linkage is there is also, should
Interaction relation is main, and shank 10 can drive presser feet 2 to decline during decline during the decline of shank 10, realize linkage
Effect, and during rise, shank 10 is gone up by the needle bar driver in machine head of embroidery machine, and presser feet 2 is then
Gone up by the restorer in presser feet 2, so both shank 10 and presser feet 2 are independent operatings during rise.
So design, for needle bar driver, needle bar driver only needs to provide the driving force of shank 10, it is not necessary to
The driving force for replying presser feet 2 is undertaken, i.e., for traditional embroidery machine, needle bar driver only assume responsibility for portion in the present embodiment
The load for dividing；
For the restorer of presser feet 2, it is only necessary to the active force for being supplied to presser feet 2 to reset, without to pressure
Pin 2 provides lower pressure, therefore for presser feet 2, can be realized using simpler mechanism, such as can be using the thinner bullet of line footpath
Spring can just be realized.Restorer in the present embodiment is exactly the spring for using line footpath thinner, such as and optional line footpath 0.2mm~
The spring steel of 0.4mm, and it is traditional to ensure stronger reset force, the spring steel of more than line footpath 0.6mm is selected substantially.
In addition, as shown in figure 5, embroidery machine has one section for the sewing stage in operation, the sewing stage refers to shank 10 in quilt
It is first push after, the stage before complete return, shank 10 is moved back and forth at a high speed within the stage, in the present embodiment, in seam
Thread in the stage, remained that avoids a gap H between the pressing plate 20 of presser feet and the pin folder 103 of shank, avoidance gap H exists
It is the axial clearance between pressing plate 20 and pin folder 103, or the lateral clearance between pressing plate and pin folder, sheet in the present embodiment
Embodiment shows axial clearance, and the implementation method of lateral clearance for details, reference can be made to embodiment 2, and it is mesh to set and avoid gap H
Be in the sewing stage, not collide or clashing between pin folder 103 and pressing plate 20.And be required in traditional embroidery machine
Shank drives presser feet return, therefore will generally lean on pin to press from both sides the band dynamic pressure plate 20 of 103 collision pressing plate 20 and go up, such design, pressure
Plate 20 will certainly produce load to pin folder 103, and load is produced equivalent to shank 10, be unfavorable for the high-speed motion of shank 10.And this
In embodiment, in the top of pressing plate 20, pin presss from both sides power of not had an effect between 103 and pressing plate 20, divides completely the activity always of pin folder 103
From the interference that will not be collided during motion etc is also pulled without other connectors, so as to reduce pressing plate to the negative of shank 10
Carry power.
Last point, traditional machine head of embroidery machine, shank 10 needs to drive presser feet 2 to go up during rise, to realize pin
Bar 10 and the effect of the synchronous rise of presser feet 2, once synchronous effect is bad, shank 10 can be collided and also returned when pushing next time
Presser feet 2 during rising, such reverse shock obviously exacerbates load to shank 10, therefore right in traditional machine head of embroidery machine
Restorer requirement in presser feet 2 is higher, if restorer needs to be carried using the thicker spring of line footpath using the spring for being
For larger restoring force, the Rapid reset of presser feet 2 is allowed, and in the present embodiment, because shank 10 and presser feet 2 are independent rises, pin
Bar 10 need not drive presser feet 2 to go up when ging up, and both need not realize accurate synchronous rise, to the restorer of presser feet 2
It is required that it is very low, it is exactly using the thinner back-moving spring 22 of line footpath, even if shank 10 is reversely hit when pushing in the present embodiment
Hit, by the reaction force also very little of back-moving spring 22, excessive load will not be produced to shank 10.
