Abstract
The invention provides a double-needle single-shuttle type sewing machine. The double-needle single-shuttle type sewing machine can produce the unique effect of two-in-one chained sewing, has a reinforcing effect and can improve the abrasion-resisting performance of fabric surfaces. The double-needle single-shuttle type sewing machine is characterized in that two sewing needles fixed to a needle rod in the sewing machine are distributed in parallel, and the needle rod is dragged manually or by a motor through a series of gears or cams to perform vertical motion; a swing shuttle hook and a bobbin assembly are arranged at the lower portion of the sewing machine, and a bobbin is located at the center of a swing shuttle and rotates under the drive of a mechanical mechanism to perform synchronous motion with the needle rod. During sewing, two mutually-parallel sewing lines are formed on one surface of a fabric, and the two-in-one chained sewing of one sewing line is formed on the other surface of the fabric.
Description
Technical field
The present invention relates to a kind of sewing machine.
Background technology
Sewing machine is widely known known by everybody, and it eliminates heavy craft sewing work for us, also substantially increases the efficiency of sewing work.
Development along with society, the requirement of textile is also being improved constantly by people, and the simplest coil stitching of conventional sewing machine and chain sewing are increasingly difficult to meet needs, and simple chain sewing is not solid especially, if one end of line is unclamped, it is possible to the defect that whole sewing can all get loose. To stitch out not only attractive in appearance but also durable chain sewing, also need to change the structure of sewing machine.
Summary of the invention
For above-mentioned situation, the present invention provides a kind of crosspointer list shuttle-type sewing machine, and it can produce the effect unique of 2-in-1 1 chain sewing, and has reinforcement effect, can increase the anti-wear performance of fabric face.
The present invention is achieved in that crosspointer list shuttle-type sewing machine is characterized by: being fixed on needle bar in sewing machine two pieces of sewing needles is parallel distribution, and shank is moved up and down by a series of gear and cam traction by manpower or motor; Shuttle hook and bobbin assemblies are located at the bottom of sewing machine, and bobbin is positioned at the central authorities of shuttle, rotate, with the synchronized movement of shank under the drive of mechanical mechanism; When sewing, forming two sutures being parallel to each other in the one side of fabric, the another side at fabric forms 2-in-1 1 chain sewing of a suture.
Bobbin is the spiral being placed in shuttle inside peg or spindle.
In sewing machine, the quantity of shuttle hook and bobbin assemblies is 1.
The effect of the present invention is:
(1). when sewing, forming two sutures being parallel to each other in the one side of fabric, the another side at fabric forms the effect unique of 2-in-1 1 chain sewing of a suture.
(2). the chain sewing solving general sewing machine generation is not solid especially, if one end of line is unclamped, it is possible to the problem that whole sewing can all get loose. And it has reinforcement effect, the anti-wear performance of fabric face can be increased.
(3). the one side at fabric forms two sutures being parallel to each other, and the color of two sutures can be different, form unique color effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the schematic diagram of crosspointer list shuttle-type sewing machine of the present invention.
In figure: 1. shank, 2. sewing needle, 3. shuttle hook and bobbin assemblies, 4. sewing machine.
Detailed description of the invention
As it can be seen, the two pieces of sewing needles 2 being fixed in sewing machine 4 on shank 1 are in parallel distribution, shank 1 is moved up and down by a series of gear and cam traction by manpower or motor.Shuttle hook and bobbin assemblies 3 are located at the bottom of sewing machine 4, and in sewing machine 4, the quantity of shuttle hook and bobbin assemblies 3 is 1; Bobbin is positioned at the central authorities of shuttle, and bobbin is the spiral being placed in shuttle inside peg or spindle; Rotate under the drive of mechanical mechanism, with the synchronized movement of shank 1; When sewing, forming two sutures being parallel to each other in the one side of fabric, the another side at fabric forms 2-in-1 1 chain sewing of a suture.
When sewing, the sewing needle of sewing machine partially passes through fabric, and two pieces of pins can pull out two coils also cross fabric. One shuttle hook and bobbin assemblies catch coil before pin pulls out, and it and pin are synchronized with the movement, once pin pull-out fabric, two coils and the coil in bobbin around and form the chain sewing of 2-in-1 1. Fabric will be drawn forward by feed dog device, when sewing needle again passes through fabric, can form the chain sewing of above-mentioned second 2-in-1 1.
The structure of the present invention is not limited to form described in embodiment, and the expansion further that those of ordinary skill in the art makes according to the present invention each falls within protection scope of the present invention.
Crosspointer list shuttle-type of the present invention sewing function produces unique 2-in-1 1 chain sewing effect.
