Abstract

Disclosed is a round feeding device used on an industrial zigzag stitching machine, which is composed of a presser foot, a needle plate, a feeding gear-plate arranged on the needle plate and a retainer driving the feeding gear-plate to rotate. The feeding gear-plate appears as the circular ring shape, and the upper surface thereof has feed dogs distributed along the ring shape, and the lower subface is provided with gear teeth distributed along the ring shape, the needle plate is opened with annular grooves for matching the gear teeth, the annular grooves are opened with transmission mouths, a transmission gear of the retainer drives the gear teeth and the feeding gear-plate to rotate through the transmission mouths, thus achieving the purpose of circular feeding by cooperation of the feed dogs and the presser foot. The utility model has few components, easy assembling and no gauffer when sewing.

Description

The circular pay-off of Zigzag sewing machine

The utility model relates to the parts of using on a kind of industrial sewing machine, use on the particularly tortuous seam machine, along the device of circular feeding.

Pay-off on the existing common tortuous seam machine generally moves forward and backward by the feeding tooth, drives cloth and moves along rectilinear direction, if want to change direction, need manually control the direction of cloth, just can achieve the goal; Like this, make troubles to the operator, and the cloth wrinkle of making, can't adapt to the requirement of special sewing work, as: circular cloth etc. made.Although on the at present external special-purpose Sewing machines circular feed mechanism is housed also, exists complex structure, cost height, shortcomings such as versatility difference.

It is a kind of simple in structure, easy to operate that the purpose of the utility model is to provide, but can reach the circular pay-off of the effect of making ROUND STITCH equally.

The technical solution of the utility model is such: it is contained in the feeding fluted disc on the needle plate by needle plate, is fixed on the presser feet on the socle and drives the retainer composition that the feeding fluted disc moves.Described feeding fluted disc is circular, and its upper surface is uniform-distribution with the feeding tooth along ring-type, and presser feet is pressed on the feeding tooth; The bottom surface of feeding fluted disc is shaped on the transmission teeth along ring-type, and needle plate is provided with the annular groove that matches with the transmission teeth, has the transmission mouth on the annular groove; Have driving cog on the retainer, driving cog stretches into the transmission mouth off and on and drives the rotation of transmission teeth.Its operation principle is such: retainer is fixed on the retainer of Sewing machines, retainer is along with motor starts, do front and back, move up and down, and drive driving cog and make moving movement and be combined into the frequently identical shuttling movement of motion with elevating movement, make the feeding fluted disc ceaselessly rotate, cooperate process with presser feet around the circumference feeding thereby finish the feeding tooth around protruding axle.

The utility model is compared with the prior art: it is few to have a member, assembling easily, advantage such as production cost is low, and do not have the sewing gauffer, the quality height.

Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model structure cutaway view.

Fig. 3 is the cutaway view of feeding fluted disc.

Fig. 4 is the upward view of Fig. 3.

Fig. 5 is the vertical view of Fig. 3.

Fig. 6 is the A-A sectional stretch-out view of Fig. 5.

Fig. 7 is the B-B sectional stretch-out view of Fig. 4.

Fig. 8 is the needle plate upward view.

Referring to Fig. 1, Fig. 2, the circular pay-off of Zigzag sewing machine be by needle plate 4, is contained in the feeding fluted disc 3 on the needle plate 4 and is fixed on the presser feet 2 on the socle 1 and drives the retainer 5 that feeding fluted disc 3 rotates to form.

Referring to Fig. 3, Fig. 4, Fig. 5, Fig. 6, feeding fluted disc 3 is circular, and its upper surface is along the internal diameter ring-type feeding tooth 3a that evenly distributes, and feeding tooth 3a is the 45 zigzag, and slightly protrudes the plane of feeding fluted disc 3; Feeding fluted disc 3 bottom surfaces are shaped on transmission teeth 3b along the external diameter ring-type, and transmission teeth 3b also is the zigzag of 45, slightly protrude to the bottom surface.

Presser feet 2 adopts plastic materials to make ring-type shape, and its size is identical with ring size of feeding tooth 3a formation, and with cloth presser on feeding tooth 3a.

Needle plate 4 be provided with feeding fluted disc 3 on internal diameter and transmission teeth the 3b protruding axle 4a and the annular groove 4b that match, the annular groove diapire has transmission mouth 4c, referring to Fig. 8, feeding fluted disc 3 places on annular groove 4b and the protruding axle 4a, and can rotate around protruding axle 4a.

Retainer 5 is provided with the driving cog 5a that matches with transmission teeth 3b, and driving cog 5a stretches on transmission mouth 4c and promotes teeth 3b and rotates.

The utility model is like this work: because retainer is installed on the retainer of Sewing machines, and along with retainer is done to go up down, side-to-side movement, make driving cog 5a also make the identical shuttling movement of frequency that moving movement and elevating movement are combined into.When driving cog 5a moves up to peak, just drop on the groove of transmission teeth 3b, after this driving cog 5a moves forward and drives transmission teeth 5a and rotates a low-angle, then driving cog 5a downwards, backward the motion, get back to and the origin-location, and it is relative with next transmission teeth 3b groove location, iterative motion like this, thereby make feeding fluted disc 3 continuously rotate around protruding axle 4a, form the feeding tooth 3a of feeding fluted disc 3 and the process that presser feet 2 constitutes around the circumference work feed, reach the purpose of the utility model.
