Description

Auxiliary device for presser foot of overlock machine

Technical Field

The utility model relates to the technical field of clothing mechanical equipment, in particular to a presser foot auxiliary device of a overlock machine.

Background

There is a process called overlock (also called serging) during the garment process. Since materials used for polyester clothing and the like are generally synthetic fibers and have relatively hard textures, yarns at the side seams of the clothing after cutting are likely to be scattered, and thus overlock is required. As shown in fig. 1, the overlock machine is a sewing machine for finishing overlock in the process of producing clothing. In the production process of the clothing, the edge seam is sewn by a special serging machine, so that the silk threads in the cloth are prevented from being scattered, and the attractive effect is achieved.

As shown in fig. 1, the existing overlock machine generally comprises a frame, a working platform and an overlock machine head, wherein cloth is manually held for feeding during operation, and under the condition that a piece of clothing or a piece of cloth is relatively large, a presser foot mechanism of the sewing machine can only fix the periphery of a cut piece, and when the middle part of the cut piece is fed for sewing, the sewing position is easily deviated due to no fixed pressing, so that sewing stitch is influenced. The sewing difficulty is greatly improved, and the production efficiency is influenced. In addition, tiny thread ends, dust and the like are easy to appear at the presser foot, the surrounding working environment is easy to be influenced, and if the dust enters the machine, the machine is damaged. For this reason, we provide a overlock machine presser foot auxiliary device.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

As shown in fig. 2 to 4, a presser foot auxiliary device for a overlock machine includes an auxiliary device body; the auxiliary device body comprises a fixing plate 1 and a bending plate 2 fixedly arranged on the fixing plate 1, wherein the fixing plate 1 comprises a horizontal part 11 and a bending part 12, and the joint of the horizontal part 11 and the bending part 12 is matched with a presser foot board; the horizontal part 11 of the fixed plate 1 comprises a rubber layer 111 close to one side of the presser foot, a dust collection plate 112 is arranged at the bottom of the rubber layer 111, and the dust collection plate 112 is in a sawtooth shape; the bending plate 2 is arranged on the bending part 12, one end of the bending plate 2 extends along the presser foot plate, and the bending plate extends to the center position of the presser foot needle falling hole and then is reversely folded back to form a folding end.

Specifically, the fixing plate 1 includes a horizontal portion 11 and a curved portion 12, where the connection between the horizontal portion 11 and the curved portion 12 is matched with the radian of the footplate, and more specifically, the curved portion 12 is consistent with the radian of the footplate, so that the fixing plate 1 can be well fit on the footplate. Further, the fixing plate 1 includes a rubber layer 111 near the presser foot, and the rubber layer 111 is near the presser foot fixing rod, which has the characteristic of reducing the rigid abrasion of the connecting component. Further, the dust collection plate 112 is arranged at the bottom of the rubber layer 111, the dust collection plate 112 is in a sawtooth shape, a sawtooth groove is formed, a through hole is formed in the bottom end of the sawtooth groove, fine substances such as a wire head can fall from the through hole, and the bottom of the dust collection plate 112 is also connected with the accommodating cavity 113, so that the purpose of temporary storage can be achieved. Further, the dust collection plate 112 is made of glass. In the friction process of the cloth and the fixing plate 1, the dust collection plate 112 made of glass generates static electricity by friction, and according to the static electricity adsorption principle, tiny thread ends and dust can be attracted to the dust collection plate 112, so that the dust can be conveniently concentrated in the zigzag grooves.

Further, the folded end of the bending plate 2 protrudes out of the presser foot plate on the same side. Still further, the folded end does not exceed the midpoint of the curved portion 12, so that the design is one of saving manufacturing cost and reducing manufacturing difficulty. Still further, the bending plate 2 is an iron sheet and is directly welded to the bending portion 12. Further, the width of the bending plate 2 does not exceed the bent end of the footpad.
