Abstract
The invention discloses a pressure foot driving mechanism for an embroidery machine. The vertical motion time of a pressure foot is controlled by a curve of a guiding seat; a control principle is that before a machine needle pieces a fabric, the fabric is pressed by the pressure foot to form temporary fixing; then the machine needle pierces the fabric and forms an embroidery with accessories; after finishing, the machine needle upwards moves; after the machine needle leaves from the fabric, the pressure foot leaves from the fabric, so that the quality and the precision of the embroidery are improved, and the phenomenon of needle breaking is effectively avoided.
Description
Technical field
The present invention relates to embroidery machine technical field, be specially a kind of embroidery machine presser foot drive.
Background technology
Fig. 1 is existing embroidery machine cam presser foot drive, and this mode drives cam rotation by the rotational band dynamic pressure foot of main shaft,
Presser feet cam rotation drives drive mechanism to operate by the curvilinear motion of gathering sill, thus drives presser feet to move up and down, and reaches to drive
The purpose of dynamic pressure foot, the power point that this mechanism drives is distant with driving point, adds the driving load of cam, reduces convex
The service life of wheel, and by the kind of drive of multiple connections, increase the quality of fit at zero position, above composite factor is led
The life-span causing cam is short, and during work, noise is big, and noise also can the very fast amplification because of the lengthening of working time simultaneously.The pressure of this structure
Foot drive mechanism, operationally, after pin initially passes through fabric, fabric is pushed down by presser feet again, and pin is not also extracted from fabric out hour hands
Fabric presser feet the most upwards moved and left fabric, and before pin, fabric is not operatively fixed pin and pierced through by presser feet in this case
Fabric, now due to machine vibration and the effect of inertia of motion, fabric is also in vibration or mobile, and these hour hands are piercing through fabric,
It is directed at embroidery pattern position out not fine, simultaneously when embroidering thicker fabric, owing to thick fabric is not first fixed by presser feet
Live, due to pulling or mobile by Herba Damnacanthi stretch bending of fabric, allow it deviate original track and cause pin to be severed.When pin leaves fabric
Time, pin is also in fabric, and presser feet has begun to leave fabric face, and fabric also can be shaken or mobile simultaneously, also results in embroidery
Pattern out is fine or broken needle phenomenon.
Summary of the invention
It is an object of the invention to provide a kind of embroidery machine presser foot drive so that during embroidery machine embroidery presser feet first under, push down
After cloth, pin pierces through fabric again, and after after piercing through fabric, pin leaves fabric, presser feet unclamps fabric again, improves embroidery quality and precision, in thorn
When embroidering heavy weave such as medicated cap, efficient solution resolution pin phenomenon.
For achieving the above object, the present invention provides following technical scheme: a kind of embroidery machine presser foot drive, sliding including first
Block, the second slide block, presser feet, eedle, shank, head cam, also include the big connecting rod moved in a circle around head cam, greatly
Connecting rod drives needle bar driver to be converted to move along a straight line up and down by circular motion around head drive shaft；Needle bar driver drives first even
Bar, first connecting rod is connected by lead with second connecting rod, and the end face at lead installs roller, and roller can be at guide holder
Moving around gathering sill in gathering sill, second connecting rod drives drive seat to move up and down around head drive shaft；Needle bar driver the most also carries
Dynamic first slide block does and moves along a straight line up and down, and the first slide block and shank are screwed formation and move up and down, and the first slide block is transported downwards
Promoting spring transmission to move downward to the second slide block time dynamic makes the second slide block contact with drive seat, and the time up and down of the second slide block is by driving
Dynamic seat carries out actual control, and eedle is screwed with shank and moves up and down as the movement locus of the first slide block.
Preferably, described second slide block is connected by screw with presser feet.
Mechanism is mainly by the time up and down of the curve controlled presser feet of guide holder, and control principle is eedle presser feet before piercing through fabric
Fabric first being pushed down formation the most fixing, then eedle pierces through fabric again, forms embroidery with accessory, and after completing, eedle moves upward,
When eedle leaves fabric, presser feet is further out fabric.
Compared with prior art, the invention has the beneficial effects as follows: 1, the precision embroidered significantly does height, by being completely fixed by fabric
Mode descend acupuncture to embroider again, when embroidering thicker fabric, broken needle will not be formed because of the shake of fabric；
2, simple in construction, connector is less, processes and installs simple and convenient, significantly reduce cost；
3, drive point and guiding point relatively near, save the kind of drive of the big arm of force and multiple spot, significantly reduce making an uproar when machine runs
Sound, is effectively improved the service life of machine and mechanism.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, to this
Bright it is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to
Limit the present invention.
Referring to Fig. 2-5, the present invention provides a kind of technical scheme: a kind of embroidery machine presser foot drive, including the first slide block 1,
Second slide block 2, presser feet 3, eedle 4, shank 16, head cam 5, also include the big connecting rod 6 moved in a circle around head cam 5,
Big connecting rod 6 drives needle bar driver 14 to be converted to move along a straight line up and down by circular motion around head drive shaft 13；Needle bar driver 14
Driving first connecting rod 7, first connecting rod 7 to be connected by lead 10 with second connecting rod 11, the end face at lead 10 installs roller 8,
Roller 8 can move around gathering sill in the gathering sill of guide holder 9, and second connecting rod 11 drives drive seat 12 in head drive shaft 13
Lower motion；Needle bar driver 14 the most also drives the first slide block 1 to do and moves along a straight line up and down, and the first slide block 1 passes through screw with shank 16
Fixing formation moves up and down, and promotes spring 15 to be transferred to the second slide block 2 and move downward and make the second slide block 2 when the first slide block 1 moves downward
Contacting with drive seat 12, the time up and down of the second slide block 2 is carried out actual control by drive seat 12, and eedle 4 and shank 16 pass through screw
Fix and move up and down as the movement locus of the first slide block 1.
Preferably, described second slide block 2 is connected by screw with presser feet 3.
Mechanism is mainly by the time up and down of the curve controlled presser feet 3 of guide holder 9, and control principle is that eedle 4 is pressed before piercing through fabric
It is the most fixing that fabric is first pushed down formation by foot 3, and then eedle 4 pierces through strong thing again, forms embroidery, eedle 4 after completing with accessory 17
Moving upward, when eedle 4 leaves fabric, presser feet 3 is further out fabric.
Above-mentioned detailed description of the invention be used for illustrate the present invention rather than limit the invention, the present invention spirit and
In scope of the claims, any modifications and changes that the present invention is made, both fall within protection scope of the present invention.
