Description
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
