2. a kind of synchronous presser foot device for transverse joint head according to claim 1, it is characterised in that: the master Moving axis installs handwheel can be with manual governing.

3. a kind of synchronous presser foot device for transverse joint head according to claim 1, it is characterised in that: when upper head After falling on minimum point under shank, shank return when, makes presser feet be pressed onto minimum point, apart from needle plate height 3- when presser feet minimum point 4mm is advisable.

4. a kind of synchronous presser foot device for transverse joint head according to claim 1, it is characterised in that: this device is suitable It is used for quilter, there is no feed dog on quilter, the formation of stitching is to fall needle speed realization by the cooperation of head movement speed , presser feet falls together also with shank when shank falls and sews, and can prevent cloth from playing fold, guarantees that sewing is wanted It asks.

Technical field

The invention belongs to quilter technical fields, and in particular to a kind of chain type quilter synchronous presser foot device.

Background technique

As demand of the modern for bedding is increasing, product quality requirement is higher and higher, and bedding are Through gradually at the theory for following state stranger, quilt is for people to use as the product that disappear fastly, and present manufacturing enterprise is replaced using machine It is continuously increased for the demand of artificial, cost of labor is constantly soaring, and recruitment is difficult, so more and more enterprises are producing now It devotes exclusive attention to output in equipment and quality, so equipment keeps updating perfect in shape and function also just at trend of the times.

Sewed in the process of the products such as core it is most important be exactly the equipment such as quilter, and the work of quilter Principle derives from sewing machine, and sewing machine is pressed on feed dog using presser feet constant force, then cooperates and fall needle realization stitching sewing, and quilting There is no feed dog on machine, the formation of stitching falls needle speed by the cooperation of head movement speed and realizes, if continuing to use sewing The common presser feet of machine formula presses on product always, will appear the case where driving cloth away when head sewing, so in thickness material seam It when processed and is not suitable for, for this process requirements, disclosure sets forth a kind of servo-actuated presser feets, when shank falls sewing It waits presser feet to fall together also with shank, can not only guarantee that sewing requires in this way, but also there is no drive cloth away.

Summary of the invention

In place of overcoming above-mentioned the deficiencies in the prior art, provide a kind of for the same of transverse joint head Foot device is walked, which uses suitable for quilter, can prevent cloth from playing fold, skidding, and upper and lower cloth dislocation passes through tune The height and stroke of seamless foot such as are suitably adapted for thick material, thin material, silk, have retractility at the various fabrics.

The purpose of the present invention is what is be achieved through the following technical solutions:

A kind of synchronous presser foot device for transverse joint head, by upper head driving shaft, shank driving big connecting rod, upper transmission shaft, big Swing arm, shank drive two connecting rods, presser feet driving swing rod, presser feet oscillating bar assembly, presser feet drive shaft, guide pad, presser bar guide sleeve, Four needle needle stands, shank, presser bar, presser feet, needle, guide sleeve, needle plate, upper head shell composition.

In the V-shaped locating slot of upper transmission shaft, fastening screw fastens in place the fastening screw of the big swing arm.It raises big Swing arm, behind shank driving big connecting rod and shank drive two connecting rods to be connected with pin shaft, shank driving big connecting rod is eccentric downwards After amount is maximum, fastening shank drives the screw above two connecting rods, this fastening screw will be fastened to position, otherwise be easy to cause shank Dislocation.Another group of shank driving big connecting rod is pushed to reach the jackscrew fastened after maximum on eccentric bushing by offset backward, before fastening Face pressure foot drives the fastening screw between swing rod and shank driving big connecting rod, can be drawn herein with screw after rotating upper main shaft to long hole Shank and presser bar synchronization lifting, shank move up and down smooth, and guide pad swings up and down according to big swing arm and is adjusted, and take advantage of a situation tight Gu main axis is smooth after fastening shank and guide pad, no dead point stuck point.It is fastened behind the top, swings model if you need to increase presser feet Enclosing can lean on downwards paraxial one end to adjust, and fastening presser feet drives swing rod.

The advantages of the present invention are:

The present invention overcomes blocked up material heap cloth, drive the technical problem of cloth away, make the smooth sewing of punishment in advance smooth precisely, synchronous by head The design of presser feet realizes workpiece and sews smooth, stable, optimized production process, improve production efficiency, reduces production process Middle generation sewing problem and make machine shut-down.

Specific embodiment

For that can further appreciate that the contents of the present invention, feature and effect, the following examples are hereby given, and cooperates attached drawing detailed Carefully it is described as follows.It should be noted that the present embodiment be it is descriptive, be not restrictive, cannot thus limit of the invention Protection scope.

A kind of synchronous presser foot device for transverse joint head drives big connecting rod (2), upper transmission shaft by upper main shaft (1), shank (3), big swing arm (4), shank drive two connecting rods (5), presser feet to drive swing rod (6), presser feet oscillating bar assembly (7), presser feet drive shaft (8), guide pad (9), presser bar guide sleeve (10), four needle needle stands (11), shank (12), presser bar (13), presser feet (14), needle (15), guide sleeve (16), needle plate (17), upper head (18) shell composition.

Upper head driving shaft (1) connects power, is connected with pulley drive mode with motor output shaft, driving shaft (1) peace Dress handwheel can drive shank driving Dalian rod piece (2) eccentric shaft rotation with manual governing, main axis, and two eccentric shafts exist On main shaft, the shank of a connection lower section drives two connecting rods (5), and part 5 and big swing arm (4) are connected on transmission shaft (3), The other end of big swing arm (4) is connect with shank (12), covers upper guide bush (16) on shank, installs eedle (15) below guide sleeve, machine To just and guaranteeing not scratch, eedle (15) band moving-wire is passed through presser feet (14) for needle (15) and presser feet (14) hole, presser feet (14) and The intermediate compress of needle plate (17) crosses cloth.Big swing arm rotation drives shank linear slide on guide pad (9).Driving shaft (1) it is another A eccentric wheel other end is connect with presser feet driving swing rod part (6), and presser feet driving swing rod (6) is connected to presser feet oscillating bar assembly (7) In drive shaft (8), drive shaft turns are equally driven, presser feet bar assembly (7) and presser bar (13) connecting band dynamic pressure foot (14) are up and down Movement.It forms connecting rod driving and drives shank (12) and presser feet (14) synchronous operation.

Drive actuated by cams link mechanism servo-actuated by upper head (18), shank (12) and presser bar (13) synchronous follow-up, Timing adjustment mode is to be pressed onto presser feet (14) when shank (12) return after falling on minimum point under upper head shank (12) Minimum point, adjustment shank drive big connecting rod (2) angle, guarantee that this position presser feet (14) fastens after minimum point, presser feet (14) is most It is advisable when low spot apart from needle plate height 3-4mm.The head work of servo-actuated presser feet cooperation spininess chain structure.It falls in shank (12) Presser feet (14) falls together also with shank (12) when sewing, just ensure that sewing requires in this way, in turn avoids driving cloth away Phenomenon directly enhances the quality of product.
