Flat seam machine retainer feeding left and right adjusting device
Technical field:
The utility model belongs to sewing machine technique, particularly to the improvement of Sewing machines retainer feeding part.
Background technology:
High and low position can not be regulated about during traditional its work of Sewing machines retainer feeding part, sometimes because the deviation of part processing causes the retainer position to monolateral inclination, cause the generation of phenomenons such as the local sideslip of cloth, also can cause phenomenons such as work feed is inhomogeneous, work feed is not smooth when serious, have a strong impact on sewing performance.
The utility model content:
The purpose of this utility model is a kind of flat seam machine retainer feeding loading amount that can left and right adjusting of design.
The utility model comprise on retainer, retainer seat, the retainer seat joint, on save connecting pin, retainer pin, retainer pin screw, feed lifting fork shape crank, crank-pin, crank-pin nut, crank block, it is characterized in that separating with saving on retainer seat and the retainer seat, utilize the elliptical shape of joint link position on retainer and the retainer seat, unclamp the joint connecting pin and realize the height adjusting of position, the retainer left and right sides, and the crank block on the retainer can be swung along the arc groove trace of prong in the feed lifting fork shape crank, to guarantee the operating accuracy of whole pay-off.
What the utility model owing to taked saved on retainer seat and the retainer seat separates, and make on the retainer seat the energy-conservation retainer that enough drives realize that the height of position, the left and right sides regulates, therefore thoroughly solve in the past defectives such as position, retainer left and right sides height can not be regulated the cloth sideslip that is caused and work feed is inhomogeneous, work feed is not smooth, guaranteed smooth and easy, linear feeding.This structural principle is simple in addition, profile is succinct, easy to adjust, part processing is easy.

The specific embodiment:
With reference to Fig. 1, Fig. 2, retainer (1) is connected with retainer pin (5) and saves on (3) on the retainer seat, and it is fixing with retainer pin screw (6), on the retainer seat joint (3) use the joint connecting pin (4) be fastened on the retainer seat (2), because of the link position ovalize of joint (3) on retainer (2) and the retainer seat, therefore only need unclamp the height adjusting that joint connecting pin (4) can be realized retainer (1) position, the left and right sides; The left end of retainer (1) is equipped with crank block (10), and crank-pin (8) passed in the hole that crank block (10) stretches into retainer (1) left end, crank block (10) is inserted in the prong arc groove of feed lifting fork shape crank (7) with crank-pin nut (9) after fixing, and make the crank block (10) on the retainer (1) can be along the arc groove trace swing of prong in the feed lifting fork shape crank (7).
