Description
Technical field
It the utility model is related to stitching process field, and in particular to a kind of double guide wheel devices for multi-needle machine.
Background technology
Surface cover of automobile seat is sewed, point common piece line and decorative thread, and decorative thread is divided into crosspointer decorative thread and spininess decoration
Line, the wherein species of spininess decorative thread are divided into locking-type line and chain type line again, and locking-type line is simpler, and the end of a thread can not stay, not loose ends,
Chain type line needs the end of a thread of reserved certain length, to ensure not loose ends.Chain type line uses more in practical applications, and with spininess
Decorative thread application is most.Spininess decorative thread can only be sewed using multi-needle machine, be sewed with other machines such as single needle sewing machine, crosspointer
Machine, cap seaming machine etc., can not realize.
Multi-needle machine is all not present when sewing fabric and common compound leather facing material close pin situation, but ox-hide cut-parts exist
When sewing decorative thread, more needlework of certain length need to be reserved in front and back end, cause multi-needle machine guide wheel by the more of predetermined length
During needlework, forward pulling force is lost, and guide wheel pressure cannot be too big, in order to avoid damaging by pressure or scratching ox-hide, can cause down a piece of spininess
Piece has the situation of close pin when sewing.The main reason for producing the problem is that sewing machine guide wheel is when by reserved line, band
The dynamic forward power of cut-parts reduces, so as to cause the generation of close pin.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems and provides a kind of double guide wheel devices for multi-needle machine,
To solve the problems, such as to produce close pin in sewing decorative thread.
The purpose of this utility model is achieved through the following technical solutions：
A kind of double guide wheel devices for multi-needle machine, connection are installed in multi-needle machine main body, including the first anterior guide wheel
Unit and second guide wheel at rear portion, first guide wheel and the second guide wheel include successively from top to bottom
Fixed link, the fixing bracket installed in fixed link lower end, the band tooth roller on fixing bracket and arranged on band tooth roller
Lower part and the drive gear ratcheting with it, the fixing bracket top be equipped with the lower positioning plate that is positioned fixed link and
Upper location-plate, interlocks bracket institution by stepping between first guide wheel and the second guide wheel and is connected.
The stepping interlocks bracket institution and is led including interlocking stent and couple axle, described gearing stent one end with second
The connection of one end with tooth roller of wheel unit, one end of the other end and couple axle that interlock stent are hinged, the other end of couple axle
It is connected with the first guide wheel, stepping interlocks bracket institution and the head of multi-needle machine main body interlocks, and can make first, second guide wheel
Unit keeps being synchronized with the movement.
The band tooth roller is using cylindrical rollers made of nylon material.
The upper location-plate lower part is equipped with resilient snubber in fixed link.
To adjust spring, the adjusting spring is set in fixed link the resilient snubber, and adjusting spring can delay
Piece high-low pressure is punched, adapts to the sewing of a variety of different size fabrics.
The drive gear is rack-mount, and drive gear is driven by motor.
The upper and lower positioning plate is reserved linear distance according to the height and cut-parts of front jocket wheel and is determined, and according to installation situation
Determine the size of upper and lower positioning plate；
The utility model adapts to a variety of difference Huan Base-on-environment working statuses, the decorative thread for the customization that can normally sew out, original one
On the basis of group guide wheel device, in addition one group of guide wheel is set, forms double Guiding wheel structures, makes sewing machine guide wheel when by reserved line,
Drive the forward power of cut-parts to keep constant, avoid causing close pin to occur, the sewing of the sewing decorative thread under the conditions of adapting to more,
Specifically advantage is：
1st, use scope is wide：Since using double Guiding wheel structures, improved multi-needle machine, drives the forward power of cut-parts to keep
Constant, adaptability is stronger, is adapted to the decoration sewer of the fabrics such as multiple leather, fabric, ox-hide.
2nd, it is safe and reliable：Guide wheel device has taken into full account safety in utilization；The guide wheel device and front jocket wheel of installation, machine sheet
Body keeps linkage, and device is mounted with to adjust spring, ensures that guide wheel changes in elastic range, avoids because of fabric thickness, hair
The raw phenomenon that gets stuck, it is ensured that sewing is smoothed out.
3rd, conformability is good：It is stronger in the different soft and hard degree and certain thickness, adaptability of fabric.
4th, maintenance is convenient：If guide wheel failure can be embodied quickly from sewing, convenient to overhaul.
