Description

TECHNICAL FIELD

[0001] The utility model relates to a special presser foot structure for sewing cotton-padded clothes belongs to the technical field of sewing machine presser foot in clothing production. BACKGROUND

[0002] The sewing machine presser foot is an indispensable component of the sewing machine, and the presser foot provided with the sewing machine is a flat head presser foot, which is generally composed of a presser foot plate and a presser foot connecting piece. The bottom surface of the presser foot plate is flat, the front end is arc-shaped and upturned, a longitudinal needle running hole or a needle running groove leading to the front end is formed in the middle of the presser foot plate, and the presser foot plate has a sharp corner or a bifurcation formed at the front end. The presser foot plate is connected to the lower pin of the presser foot connecting piece, and the upper part of the presser foot connecting piece is fixed to the sewing machine by screws. The presser foot is used to press the fabric being sewn and works cooperatively with the needle and the feed dog.

[0003] In the process of clothing production, when the fabric or auxiliary material of the cotton-padded clothes, cotton quilt, etc. contains cotton and fluffy cotton, the sewing equipment often cannot meet the process requirements. During the sewing process, the sharp corner at the front end of the original presser foot hooks the cotton, causing winding and broken needle and thread, etc. The fabric cannot advance, and the problem of smooth sewing is difficult to solve, which not only damages the machine but also wastes time.

[0004] CN221797842U discloses a presser foot cap, which comprises a fixing component and a presser foot protective sleeve. The fixing component is detachably connected to the presser foot protective sleeve. The presser foot protective sleeve is a cloth bag with an open end. During use, the fixing component is fixed to one end of the presser foot protective sleeve, and the presser foot protective sleeve is used to cover the sharp position of the upturned front end of the presser foot plate. The fixing component is used to firmly fix the presser foot protective sleeve to the presser foot of the sewing machine, preventing the presser foot protective sleeve from falling off the sharp position of the upturned front end of the presser foot plate during sewing. This technology solves the problem of the presser foot easily hooking the cotton, but it is relatively cumbersome to use the presser foot protective sleeve to cover the sharp position of the upturned front end of the presser foot plate and then use the fixing component to connect and fix the presser foot to the presser foot of the sewing machine. In addition, when sewing, the presser foot protective sleeve covering the sharp position of the upturned front end of the presser foot plate will block the advance of the fabric, affecting the smooth advance of the fabric and thus affecting the sewing quality. SUMMARY

[0005] The utility model aims at providing a special presser foot structure for sewing cotton-padded clothes, which can avoid the problem of the presser foot plate hooking the cotton during sewing, causing winding and broken needle and thread, etc., ensure the smooth advance of the fabric, reduce the difficulty of the sewing process, improve the work efficiency of clothing production, and be convenient to use.

[0006] The utility model is implemented by the following technical solutions:

[0007] The utility model discloses a presser foot plate, presser foot connecting piece, its characterized in that: be equipped with a circle metal fence around presser foot plate at the both sides and the front end of presser foot plate, and the smooth connection of metal fence and presser foot plate, and metal fence is relative to presser foot plate and presents the arc face and is upturned, forms a boat type structure.

[0008] The metal fence is a stainless steel plate or a copper plate.

[0009] The metal fence is welded to the presser foot plate.

[0010] The metal fence is welded to the edge of the presser foot plate, and the bottom surface of the metal fence and the presser foot plate is flush.

[0011] The bottom surface of the presser foot plate is welded to the metal fence, and the needle hole or the needle slot of the presser foot plate is not blocked.

[0012] The utility model discloses a presser foot plate, presser foot connecting piece, its characterized in that: be equipped with a circle metal fence around presser foot plate at the both sides and the front end of presser foot plate, and the smooth connection of metal fence and presser foot plate, and metal fence is relative to presser foot plate and presents the arc face and is upturned, forms a boat type structure. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 It is the structure diagram of the utility model;

[0014] Figure 2 It is the plane view of metal fence.

[0015] In the drawing: 1-presser foot connecting piece;2-needle hole;3-presser foot plate;4-metal fence. DETAILED DESCRIPTION

[0016] Referring to the drawings, the utility model includes: presser foot plate 3, presser foot connecting piece 1, is equipped with a circle metal fence 4 around presser foot plate and is welded to the both sides and the front end of presser foot plate 3, and metal fence 4 is stainless steel plate or copper plate, and metal fence 4 adopts to make a mould, to prune, to polish, to bend into shape.Metal fence 4 and presser foot plate 3 smooth connection, and metal fence 4 is relative to presser foot plate 3 and presents the arc face and is upturned, forms a boat type structure.

[0017] In order to guarantee that metal fence 4 and presser foot plate 3 connect smooth, metal fence 4 and presser foot plate 3 adopt one of following connection modes.

[0018] (1) metal fence 4 and the edge tin soldering connection of presser foot plate 3, and the bottom surface of metal fence 4 and presser foot plate 3 is flush;After welding, must carry out polishing.

[0019] (2) the bottom surface of the presser foot plate 3 is placed on the metal fence 4 for tin soldering, and the needle hole 2 of the presser foot plate 3 is not blocked; this soldering mode has large soldering contact area, firm soldering, and relatively simple process.

[0020] When the fabric or auxiliary material with cotton and fluffy cotton such as cotton clothes and cotton quilt is encountered, the original presser foot on the sewing machine is only needed to be removed by using a screwdriver and replaced by the utility model. Since the utility model increases the bottom surface area of the presser foot plate, increases the height of the front end of the presser foot plate, and the bottom surface is smooth and blocks the sharp corner of the front end of the original presser foot plate, the utility model is more suitable for sewing the fabric or auxiliary material with cotton and fluffy cotton such as cotton quilt, has high efficiency, good quality, and is more suitable for enterprise assembly line operation.
