Abstract
An improved 5-thread overedger has an eccentric wheel sleeved by a bearing whose shell is linked with flange, pin axle and extended arm, which are in a same semi-circle. The cutting knife is controlled by the flange via connecting rod and rocker. Said pin axle linked with cloth feeding connecting-rod has a slide block on it to regulate the cloth feeding teeth. Its advantages include compact structure, automatic running and high quality.
Description
The present invention relates to a kind of improvement of 5-thread overedger, it both had been used for five-string overlock seaming, also applicable to four lines, three-way operation.
Overlock machine still exists complex structure at present, parts are many, problems such as manufacturing cost height, for this reason, we once proposed a kind of 5-thread overedger in Chinese patent CN95107520.9 number, five line bearded needle axles of this overlock machine link to each other with two ball journals, five line bearded needles are subjected to their common traction and do the elliptical orbit swing, it also is equipped with two eedles that are spaced from each other and become certain drift angle in addition, little curved needle shaft is that the upper arm with ball journal one end joins, and joins and the large bending needle axle is a underarm with another ball journal one end.The transmission mechanism of this 5-thread overedger is simple, and is easy to use, but that the parts that have are provided with is undesirable, and the complete machine action is dumb.
Task of the present invention provides a kind of practical modified five line style overlock machines, its compact conformation, and complete machine is gone slick, reliable in quality, few easy workout part keeps in repair easy.
Task of the present invention is to finish in such a way, a turning cylinder is respectively settled in the eccentric wheel both sides of this modified 5-thread overedger, one of them is a main shaft, another is an outer shaft, a bearing in eccentric outer race, a shell is being overlapped in the outside of bearing, a flange of shell and its outside, cantilever arm and bearing pin connect together, and flange and cantilever arm, bearing pin is in same semicircle, and flange is by the advance and retreat of cutter connecting rod control cutting knife, and bearing pin and feed dog connecting rod join, a slide block is housed on bearing pin, and slide block also disposes a release handle.This 5-thread overedger also has five eedles, and it is equipped with two eedles that are in certain drift angle in the end of eedle rocking bar, also has one five line crochet hook on the next door of large and small looper.When overlock machine is worked, eccentric wheel is ceaselessly running under main shaft drives, making eedle connecting rod and eedle rocking bar drive two eedles moves up and down, two ball journals draw large and small looper along certain radian swing, five line bearded needles are under the combined drawing of two other ball journal, catch on the stitching of eedle at the motion upper half, and when lower half, the stitching of five line bearded needles is caught on by eedle instead.
The invention will be further elaborated below in conjunction with accompanying drawing.
Fig. 1 is a modified 5-thread overedger structure chart of the present invention.
As seen from the figure, this modified 5-thread overedger is the five eedles motions of two turning cylinders drives by an eccentric wheel 1 and both sides, main shaft 2 one ends are fixed on the eccentric wheel 1, ball journal 4,5 and eedle connecting rod 6 are arranged on the outer shaft 3, the outer race of eccentric wheel 1 bearing 7, there is a shell 8 bearing 7 outsides, shell 8 connects together with flange 9, bearing pin 10, cantilever arm 11, and flange 9 is in same semicircle with bearing pin 10, cantilever arm 11, flange 9 is by cutter connecting rod 12, and cutting knife rocking bar 13 is controlled the advance and retreat of cutting knifes 14.Bearing pin 10 joins with feed dog connecting rod 15, and a slide block 16 of regulating the dog thickness is housed on the bearing pin 10, and a release handle 17 also is equipped with on its next door, and the adjusting of slide block 16 is to realize by the release handle above it 17.The other end upper arm and the little curved needle shaft 18 of ball journal 4 join, thereby draw little looper 19 swings, the other end underarm of ball journal 5 then joins with large bending needle axle 20, its traction large bending needle 21 is ceaselessly swung, two eedles 23 that eedle connecting rod 6 drives eedle rocking bar 22 ends move up and down, ball journal 24 joins with the rotating shaft of eedle rocking bar 22, five line bearded needle axles 25 and ball journal 24, bead axle 26 is connected, bead axle 26 be subjected to large bending needle axle 20 be pulled among a small circle in move up and down, ball journal 24 and 26 common traction five line bearded needles 27 are done the motion of elliptic orbit in more among a small circle, like this eedle 23 on, following motion, large bending needle 21 and little looper 19 are along the swing of certain radian, add the elliptic motion of five line bearded needles 27, cooperatively interact and finish the five-string overlock seaming task.Cantilever arm 11 is to join with feed dog lifting rocking bar 28, and feed dog lifting rocking bar 28 is made up of the rocking bar of two samples different in size.
