Description
Technical field
The invention belongs to sewing machine apparatus field, refer in particular to the pin bit architecture of a kind of novel crank arm type seaming machine.
Background technology
Crank arm type piece special type machine, is a kind of elbow cartridge type, for men's clothing, women's dress, easy suit, cowboy
The splicing sewing such as clothing, shirt, working clothing, raincoat.The pin position of current arm-type cigarette piece special type machine is in reality
There is material grasping power when joints is crossed in border application inadequate so that cross joints and slow, have blocking existing
As, thus it is not smooth to result in sewing, the close phenomenon of change of needle gage.Additionally on needle plate, pinprick hole is shorter, it may appear that
The phenomenon that take-up effect is bad.
Summary of the invention
It is an object of the invention to provide a kind of offer sewing operation process smooth and easy, excessively without blocking during joints,
Needle gage is without becoming close phenomenon, the pin bit architecture of the crank arm type seaming machine that stitching take-up effect is the most novel.
The object of the present invention is achieved like this:
The pin bit architecture of a kind of crank arm type seaming machine, including presser bar, presser feet, needle plate, feeding rod, work feed
Tooth, described presser feet is fixedly connected on presser bar lower end, and presser bar drives presser feet to pump, described
Needle plate is fixed on the frame upper surface below presser feet, and described cloth conveying teeth is fixedly connected on the front end of feeding rod, send
Cloth tooth upper surface is provided with the tooth of some rows, and described needle plate forms the tooth with some rows matches several
Groove, the tooth of some rows stretches in corresponding groove below needle plate one by one, and feeding rod drives cloth conveying teeth to do
Front-rear reciprocation movement, the tooth of some rows does front-rear reciprocation movement in corresponding groove, and described presser feet includes propping up
Support part and pressure foot, the upper end of supporting part is fixing with presser bar lower end to be connected, the lower end of supporting part and pressure foot
Hinged, the front end of pressure foot is inclined upwardly to extend and forms guide portion.
The angle ＜ 40 ° that 30 ° of ＜ guide portions are formed with needle plate.
Angle=35 ° that guide portion is formed with needle plate.
The vertical pressure foot in both sides of described pressure foot extends two arc-shaped guide plates obliquely.
Described cloth conveying teeth is provided with the tooth of five rows, and centre three toothrow in the tooth of five rows is separated into anterior cloth conveying teeth
And rear portion cloth conveying teeth, described needle plate forms eight grooves one to one of the tooth with five rows, middle six
Individual groove is divided into three anterior work feed grooves and three rear portion work feed grooves, and any one anterior work feed groove is with corresponding
Rear portion work feed groove between form pinprick hole.
The width of described cloth conveying teeth is 19.5mm, a length of 42mm of cloth conveying teeth.
The rear upper end of any one groove described all forms guide inclined-plane.
Described supporting part is obliquely installed to the opposite direction of charging, forms binder inclination angle, 70 ° of ＜ binder inclination angle ＜
80°。
Described binder inclination angle=73 °.
Described supporting part is the " u "-shaped structure that Open Side Down, and two lower ends of supporting part are hinged on the two of pressure foot
Side.
The present invention highlights and useful having the technical effect that compared to existing technology
1, the present invention is inclined upwardly by the front end of pressure foot and extends the design forming guide portion, it is thus possible to coordinate
Cloth conveying teeth realizes the more smooth and easy of feeding, blocking phenomenon when solving joints.
2, the design of the angle ＜ 40 ° that the present invention is formed with needle plate by 30 ° of ＜ guide portions, in this angle
In the range of, wider effective charging aperture can be kept further, and make sewing steadily feed, so that work feed
Tooth feeding more smooth and easy, blocking phenomenon when solving joints.
3, the design of angle=35 ° that the present invention is formed with needle plate by guide portion, it is determined that optimal angle,
Reach the effect of best drag reduction guide, thus allow the most smooth and easy of cloth conveying teeth feeding, solved and connect
Blocking phenomenon during head.
4, the present invention design by arc-shaped guide plate, thus make cloth conveying teeth feeding more steady, sewing is difficult to rise and fall.
5, the present invention is by the design of the tooth of five rows so that the width of cloth conveying teeth is wider, so that in pin position
Cloth conveying teeth has preferably effectively feeding area and feeding power, setting by anterior cloth conveying teeth and rear portion cloth conveying teeth
Meter so that cross joints time have effective feeding power, it is achieved charging, feeding smooth and easy.
6, the width of cloth conveying teeth of the present invention is 19.5mm, a length of 42mm of cloth conveying teeth, is not affecting complete machine
In the case of, have selected width the widest, the cloth conveying teeth that length is grown as far as possible, so that giving in pin position
Cloth tooth has the most effectively feeding area and feeding power.
7, the rear upper end of any one groove of the present invention all forms guide inclined-plane, such design, reduces seam
Material resistance on needle plate, further increases the smooth and easy of feeding.
8, the present invention is obliquely installed to the opposite direction of charging by supporting part, forms binder inclination angle, 70 ° of ＜ pressures
The design of material inclination angle ＜ 80 °, so that supporting part has preferable pressure-plate-force, and pressure-plate-force is in face of charging
Direction, thus make sewing operation more stable.
9, the supporting part of the present invention is the " u "-shaped structure that Open Side Down, and two lower ends of supporting part are hinged on pressure
The both sides of sole, such design makes the work of pressure foot more stable, is difficult to double swerve, so that seam
Effect processed is more preferable.
