Description
Technical field
The invention belongs to clothes manufacturing equipment technical fields, are related to a kind of muti needle chainstitch m/c, the big pressure of especially a kind of muti needle chainstitch m/c
Foot modular construction.
Background technique
The opening at the shirtfront position of clothes is known as left front, and left front is main component most eye-catching in many garment decorations, it
Set off the appearance for showing that fashionable dress is gorgeous mutually with collar, sack, the style of left front emerges one after another ever-changing.Currently, left front
It is machined with two ways, one is general sewing machine sewn by hand is used, another kind is by automatic muti needle chainstitch m/c automatic sewing；From
Dynamic muti needle chainstitch m/c is a kind of a sewing machine specially designed and developed for processing the left front of the clothes neckline part such as T-shirt position, its energy
Manufacturing procedure is reduced, production technology is simplified, to effectively promote working efficiency.Muti needle chainstitch m/c generally includes big presser foot component structure；
The course of work of muti needle chainstitch m/c is: big presser feet, which travels forward, pushes down cloth, and presser feet cylinder movement pushes big presser feet to push down cloth
Material, with the sewing of big presser feet and the mobile realization cloth of head, moving knife and stationary knife cooperate cutting cloth in sewing process, are
The optimal sewing efficiency of realization, big presser feet need to push down cloth and maintain a certain distance with suture.Left front presses knife fixing plate knife
There are many width left fronts for mouth distance point, and when replacing left front specification, two sewing thread distances change, in order to obtain good seam
It threads effect, presser feet arm needs to adjust the spacing of two-arm with the variation of sewing thread, due to needing manually to be adjusted, production efficiency
It reduces, and high is wanted to the technical requirements of operator, large labor intensity, nor between the presser feet that can accurately adjust
Spacing, it cannot be guaranteed that between presser feet and suture spacing stabilization, cause stitching that cannot reach unified beautiful requirement.In addition, by
It is be easy to cause without effective press material structure when the big presser feet intermediate region cloth protrusion in left and right in the big presser feet intermediate region in left and right
The inaccuracy of sewing and cloth cutting.
Chinese patent (publication number: CN105200675A, authorized announcement date: 2015-12-30) discloses a kind of muti needle chainstitch m/c pressure
The left and right presser feet that foot automatic adjusting mechanism includes left and right presser feet arm and is arranged on left and right presser feet arm, in presser feet mounting rack
On be provided with regulating mechanism, left and right presser feet arm is connect with regulating mechanism, and regulating mechanism movement is adjusted between left and right presser feet arm
Spacing between spacing and then adjusting left and right presser feet, the movement of regulating mechanism are controlled by sewing Electrical Control；Regulating mechanism includes
Screw rod on presser feet mounting rack is set, and screw rod is left and right screw rod, and left and right presser feet arm is arranged on screw rod, is driven by driving mechanism
Dynamic screw rod adjusts the spacing between left and right presser feet arm forward or reverse；Driving mechanism includes motor, is provided on motor shaft
Active synchronization belt wheel is provided with driven synchronous pulley in screw rod respective end, passes through synchronous band connection, motor between two synchronous pulleys
Screw rod is driven to realize the adjusting of spacing between left and right presser feet forward or reverse forward or reverse.
Moving left and right for big presser feet is realized by structures such as screw rods in above patent document, but should structure is complicated and cost
It is high.
Summary of the invention
The present invention addresses the above problems in the prior art, provides a kind of big presser foot component structure of muti needle chainstitch m/c, this
The technical problems to be solved by the invention are: how to provide a kind of of simple structure and low cost and can adjust between two groups of big presser feets
Away from the big presser foot component of muti needle chainstitch m/c.
Object of the invention can be realized by the following technical scheme:
A kind of big presser foot component structure of muti needle chainstitch m/c, the big presser feet arm in a left side and right big presser feet arm including spacing side by side setting,
