Abstract
The utility model relates to an unfolding device for a needle feeding lockstitch sewing machine which belongs to the unfolding device for a GC6360 type needle feeding lockstitch sewing machine. The utility model solves the technical problems that the traditional lockstitch sewing machine has high labor intensity and low efficiency. The technical scheme of the utility model is that the unfolding device for the needle feeding lockstitch sewing machine comprises an eccentric wheel connecting rod, a needle rod swinging shaft, an unfolding volume regulating crank, a big crank, a pull rod, a torsion spring and an unfolding fork, wherein the lower part of the unfolding volume regulating crank is arranged on the needle rod swinging shaft; a rectangular hole on the upper part of the unfolding volume regulating crank is connected with the eccentric wheel connecting rod through a regulating screw; the upper part of the big crank is arranged on the left end face of the needle rod swinging shaft; the lower part of the big crank is connected with the back end of the pull rod through a pin shaft; the front end of the pull rod is connected with the unfolding fork; the torsion spring is arranged on the pin shaft; and one end of the torsion spring is arranged on the big crank while the other end is arranged on the pull rod so as to control the pressure of the unfolding fork on the working objects.
Description
Technical field
The utility model relates to a kind of pin feeding flat seam machine with eating the Zhe device, and it belongs to the matching used Zhe of the eating device of a kind of GC6360 type pin feeding flat seam machine.
Background technology
In the processing of synthetic tuft cap, cap wall felt is with before crown combines, and cap wall felt need be eaten Zhe in advance to adapt to the crown size.In the past, cap wall felt was eaten the Zhe operation and will be pushed away Zhe by hand and send under the flat seam machine presser feet and make, and this operation is to operative employee's specification requirement height, and labour intensity is big, inefficiency, and be difficult to guarantee to eat the Zhe uniformity, can't satisfy needs of scale production in enormous quantities.
Summary of the invention
The purpose of this utility model is to solve existing flat seam machine to exist and eat the big and inefficient technological difficulties of Zhe labour intensity, and provide a kind of time saving and energy saving, efficient is high, sewing quality good and the pin feeding flat seam machine that can satisfy large-scale production needs in enormous quantities with eating the Zhe device.
The utility model for the technical scheme that solves above-mentioned technological difficulties and adopt is: a kind of pin feeding flat seam machine is with eating the Zhe device, comprise connecting rod of eccentric wheel (3) and shank swinging axle (1), wherein: it comprises that also eating the Zhe amount regulates crank (2), big crank (4), pull bar (5), torsion spring (6) and eat Zhe fork (7), the bottom of eating Zhe amount adjusting crank (2) is arranged on the shank swinging axle (1), the oblong aperture of eating the top setting of Zhe amount adjusting crank (2) is connected with connecting rod of eccentric wheel (3) by adjusting screw, the top of big crank (4) is contained in the end in shank swinging axle (1) left side, the bottom of big crank (4) is connected by the rear end of bearing pin with pull bar (5), the front end of pull bar (5) with eat Zhe fork (7) and be connected, torsion spring (6) is located on the bearing pin and an end of torsion spring (6) is contained on the big crank (4), the other end of torsion spring (6) is contained on the pull bar (5), eats the pressure of Zhe fork (7) to working substance with control.
Because the utility model adopted technique scheme, solved existing flat seam machine and existed and eat the big and inefficient technological difficulties of Zhe labour intensity.Therefore, compare with background technology, the utlity model has simple to operation, time saving and energy saving, efficient is high, sewing quality good and can satisfy advantages such as large-scale production needs in enormous quantities.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in drawings, a kind of pin feeding flat seam machine in the present embodiment is with eating the Zhe device, comprise connecting rod of eccentric wheel (3) and shank swinging axle (1), wherein: it comprises that also eating the Zhe amount regulates crank (2), big crank (4), pull bar (5), torsion spring (6) and eat Zhe fork (7), the bottom of eating Zhe amount adjusting crank (2) is arranged on the shank swinging axle (1), the oblong aperture of eating the top setting of Zhe amount adjusting crank (2) is connected with connecting rod of eccentric wheel (3) by adjusting screw, the top of big crank (4) is contained in the end in shank swinging axle (1) left side, the bottom of big crank (4) is connected by the rear end of bearing pin with pull bar (5), the front end of pull bar (5) with eat Zhe fork (7) and be connected, torsion spring (6) is located on the bearing pin and an end of torsion spring (6) is contained on the big crank (4), the other end of torsion spring (6) is contained on the pull bar (5), eats the pressure of Zhe fork (7) to working substance with control.
The course of work of the present utility model is: working substance is placed on eats Zhe and pitch under the 7 peaceful presser feets, start, eat the Zhe amount by connecting rod of eccentric wheel 3 drives and regulate crank 2, realize the 1 positive and negative rotation of shank swinging axle, do by shank swinging axle 1 drive big crank 4 again and seesaw, thereby drive pull bar 5 and eat Zhe fork 7 and do and seesaw, because making, the effect of the torsion spring 6 between big crank 4 and the pull bar 5 eats 7 pairs of working substances generations of Zhe fork certain pressure, therefore, eating Zhe fork 7 can release working substance Zhe and send under the presser feet and make when travelling forward.
