Abstract
The invention discloses a kind of embroidery machine presser foot drives, pass through the time up and down of the curve controlled presser feet of guide holder, control principle is that eedle presser feet before piercing through fabric first pushes down fabric to form temporary fixation, then eedle pierces through fabric again, it is formed and is embroidered with accessory, eedle moves upwards after the completion, and presser feet is further out fabric after eedle leaves fabric, embroidery quality and precision are improved, broken needle phenomenon is effectively solved.
Description
Technical field
The present invention relates to embroidery machine technical field, specially a kind of embroidery machine presser foot drive.
Background technique
Fig. 1 is existing embroidery machine cam presser foot drive, this mode drives presser feet driving convex by the rotation of main shaft
Wheel rotation, the rotation of presser feet cam drive driving mechanism operating by the curvilinear motion of guide groove, so that presser feet be driven to do fortune up and down
It is dynamic, achieve the purpose that drive presser feet, farther out, the driving for increasing cam is negative for the power point of this mechanism driving and driving point distance
It carries, reduces the service life of cam, and by the kind of drive of multiple point connections, increase the cooperation precision at zero position, with
Upper composite factor causes the service life of cam short, and noise is big when work, while noise very fast because of the lengthening of working time can also be put
Greatly.The presser foot drive of this structure, at work, presser feet again pushes down fabric after needle initially passes through fabric, and needle goes out from fabric
Carry out hour hands and do not extract fabric presser feet also and just moved upwards to leave fabric, presser feet is not operatively by fabric before such case knit stitch
Fixed pin has just pierced through fabric, and at this time due to the effect of inertia of machine vibration and movement, fabric is also in vibration or movement, at this time
Needle is piercing through fabric, it is not fine to be directed at the pattern position embroidered and, while when embroidering thicker fabric, due to thick
Fabric is not fixed first by presser feet, and since the pulling or movement of fabric are by embroidery needle stretch bending, allowing it to deviate original track leads to needle
It is severed.When needle leaves fabric, also in the fabric, presser feet has begun leaves fabric surface to needle, and fabric also will shake simultaneously
Or it is mobile, also result in that the pattern embroidered and is not fine or broken needle phenomenon.
Summary of the invention
The purpose of the present invention is to provide a kind of embroidery machine presser foot drives, so that presser feet is first when embroidery machine is embroidered
Under, needle pierces through fabric again after pushing down cloth, and presser feet unclamps again fabric after needle leaves fabric after puncture fabric, improves embroidery quality and essence
Degree effectively solves broken needle phenomenon when embroidering heavy weave such as cap.
To achieve the above object, the invention provides the following technical scheme: a kind of embroidery machine presser foot drive, including
One sliding block, the second sliding block, presser feet, eedle, shank, head cam further include the big connecting rod to move in a circle around head cam, greatly
Connecting rod drives needle bar driver that circular motion is converted to linear motion up and down around head drive shaft；Needle bar driver drives first
Connecting rod, first connecting rod are connect with second connecting rod by guide post, install roller in the end face of guide post, roller can be in guide holder
Guide groove in around guide groove move, second connecting rod drive drive seat around head drive shaft move up and down；Needle bar driver is simultaneously
The first sliding block is also driven to do linear motion up and down, the first sliding block and shank are screwed to form up and down motion, the first sliding block
Push the spring, which is transferred to the second sliding block and moves downward, when moving downward contacts the second sliding block with drive seat, above and below the second sliding block
Time carries out practical control by drive seat, and eedle is screwed with shank and does as the motion profile of the first sliding block
Lower movement.
Preferably, second sliding block and presser feet pass through screw connection.
Mechanism mainly passes through the time up and down of the curve controlled presser feet of guide holder, and control principle is that eedle is piercing through fabric
Preceding presser feet first pushes down fabric to form temporary fixation, and then eedle pierces through fabric again, with accessory formed embroider, after the completion eedle to
Upper movement, when eedle leaves fabric, presser feet is further out fabric.
Compared with prior art, the beneficial effects of the present invention are: the precision of 1, embroidery substantially does height, by the way that fabric is complete
Fixed mode again embroider by knit stitch, when embroidering thicker fabric, will not because of fabric shake and form broken needle；
2, structure is simple, and connector is less, processes and install simple and convenient, significantly reduces cost；
3, driving point and guiding point are closer, save the kind of drive of the big arm of force and multiple spot, significantly reduce machine operation
When noise, effectively improve the service life of machine and mechanism.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.
Fig. 2-5 is please referred to, the present invention provides a kind of technical solution: a kind of embroidery machine presser foot drive, including first
Sliding block 1, the second sliding block 2, presser feet 3, eedle 4, shank 16, head cam 5, further include move in a circle around head cam 5 it is big
Connecting rod 6, big connecting rod 6 drive needle bar driver 14 that circular motion is converted to linear motion up and down around head drive shaft 13；Shank
Driver 14 drives first connecting rod 7, and first connecting rod 7 is connect with second connecting rod 11 by guide post 10, in the end face of guide post 10
Roller 8 is installed, roller 8 can move in the guide groove of guide holder 9 around guide groove, and second connecting rod 11 drives drive seat 12 around machine
Head drive shaft 13 moves up and down；Needle bar driver 14 also drives the first sliding block 1 to do linear motion up and down simultaneously, the first sliding block 1 with
Shank 16 is screwed to form up and down motion, when the first sliding block 1 moves downward push the spring 15 be transferred to the second sliding block 2 to
Lower movement contacts the second sliding block 2 with drive seat 12, and the time up and down of the second sliding block 2 carries out practical control, machine by drive seat 12
Needle 4 is screwed with shank 16 and moves up and down as the motion profile of the first sliding block 1.
Preferably, second sliding block 2 passes through screw connection with presser feet 3.
Mechanism mainly passes through the time up and down of the curve controlled presser feet 3 of guide holder 9, and control principle is that eedle 4 is piercing through
Presser feet 3 first pushes down fabric to form temporary fixation before fabric, and then eedle 4 pierces through strong object again, is formed and is embroidered with accessory 17, completes
Eedle 4 moves upwards afterwards, and when eedle 4 leaves fabric, presser feet 3 is further out fabric.
Above-mentioned specific embodiment is used to illustrate the present invention, rather than limits the invention, of the invention
In spirit and scope of protection of the claims, to any modifications and changes that the present invention makes, protection model of the invention is both fallen within
It encloses.
