Technical Field

[0001] This utility model relates to the field of side-sewing machine technology, and in particular to a presser foot of a double oblique needle rocker arm side-sewing machine. Background Technology

[0002] In existing technology, the bottom of a regular presser foot is flat. Because the sole of the shoe will protrude, it is easy to deviate when the regular presser foot is directly applied to the rocker arm side seam machine. It also has greater resistance, which increases the difficulty of sewing and reduces the processing speed. Therefore, the binding strip is first sewn to the upper and then glued to the sole. This method not only makes it easy for the gap between the two to be exposed, but also makes it easy for the glue marks to be exposed, thus affecting the normal sale of the shoes. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a presser foot for a double oblique needle rocker arm side sewing machine. By setting an avoidance groove at the bottom of the presser foot plate to form a stepped surface, it can adapt to the situation of the shoe upper and sole. The binding strip can be directly sewn between the shoe upper and sole, which can not only cover up the defects, but also make the binding strip more three-dimensional.

[0004] This utility model discloses a presser foot for a double oblique needle rocker arm side sewing machine, including a presser foot handle and a presser foot plate. The presser foot plate is provided with a material feeding hole, a first needle drop hole, and a second needle drop hole. The material feeding hole includes a first material feeding area, a corner area, and a second material feeding area. The second material feeding area is connected to the first material feeding area through the corner area and turns to the front side of the first material feeding area. The first needle drop hole overlaps on the corner area, and the second needle drop hole is located on the rear side of the first material feeding area. The feature is that an avoidance groove is provided on the bottom left side of the presser foot plate, forming a stepped structure with the bottom of the presser foot plate being higher on the left and lower on the right.

[0005] A further feature of this invention is that the rear sidewall of the first material feeding area extends upward to form a blocking wall, which separates the first needle hole and the second needle hole, and an arc-shaped limiting groove is provided on the corner area corresponding to the position of the first needle hole.

[0006] A further feature of this invention is that a support frame is provided on the presser foot plate above the second material feeding area.

[0007] A further feature of this invention is that the front end of the pressure foot plate extends upward to form an extension plate, the abutment frame is a rod, one end of the rod is fixed or integrally mounted on the barrier wall, and the other end is fixed or integrally mounted on the extension plate.

[0008] A further feature of this invention is that the presser foot plate is also provided with a cotton core hole.

[0009] A further feature of this invention is that the front side of the pressure foot plate has an arc-shaped surface.

[0010] The beneficial effects of this utility model are as follows: When in use, it is assembled onto a rocker arm type side sewing machine, the binding strip is threaded through the binding material hole, and the sole with the shoe upper attached is directly fitted onto the rocker arm. At this time, the binding strip passes through the first material threading area, the corner area and the second material threading area, so that the front side of the binding strip will be relatively bent to form an approximate J-shape. When sewing, a single hidden thread will be formed (when the first needle hole is located to the left of the second needle hole, the hidden thread part is sewn to the sole; when the first needle hole is located to the right of the second needle hole, the hidden thread part is sewn to the upper). The binding strip can be directly sewn between the upper and the sole, which can not only achieve the connection between the two, but also avoid the joint between the upper and the sole being exposed. Furthermore, the binding strip directly sewn together is more three-dimensional and complete. Attached Figure Description

Detailed Implementation

[0012] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] This utility model discloses a presser foot for a double oblique needle rocker arm side sewing machine, including a presser foot handle 1 and a presser foot plate 2. The presser foot plate 2 is provided with a material-filling through hole 3, a first needle drop hole and a second needle drop hole 4. The material-filling through hole 3 includes a first material-filling area 31, a corner area 32 and a second material-filling area 33. The second material-filling area 33 is connected to the first material-filling area 31 through the corner area 32 and turns to the front side of the first material-filling area 31. The first needle drop hole overlaps on the corner area 32 and the second needle drop hole 4 is located on the rear side of the first material-filling area 31. In this utility model embodiment, an avoidance groove 5 is provided on the bottom left side of the presser foot plate 2, forming a stepped structure with the bottom of the presser foot plate 2 being higher on the left and lower on the right.

[0014] Using the above technical solution, when in use, it is assembled onto a rocker arm side seam machine. The binding strip is threaded through the binding material perforation 3, and the sole with the shoe upper attached is directly fitted onto the rocker arm. At this time, the binding strip passes through the first material threading area 31, the corner area 32, and the second material threading area 33, so that the front side of the binding strip will bend to form an approximate J-shape. When sewing, a single hidden thread will be formed (when the first needle hole is located to the left of the second needle hole 4, the hidden thread is sewn to the sole; when the first needle hole is located to the right of the second needle hole 4, the hidden thread is sewn to the upper). The binding strip can be directly sewn between the upper and the sole, which can not only connect the two but also prevent the joint between the upper and the sole from being exposed. Furthermore, the binding strip directly sewn together is more three-dimensional and complete.

[0015] The rear sidewall of the first threading area 31 extends upward to form a blocking wall 6. The blocking wall 6 is separated between the first needle hole and the second needle hole 4. The corner area 32 is also provided with an arc-shaped limiting groove 7 corresponding to the position of the first needle hole. The blocking wall 6 can prevent the binding strip from running above the second needle hole 4, making it more stable during sewing. The arc-shaped limiting groove 7 can provide support and guidance for the needle when it drops, making it more accurate and stable when it drops.

[0016] A support frame 8 is provided on the presser foot plate 2 above the second material feeding area 33, which can play an auxiliary supporting role when the edge banding strip is cut, so that the edge banding strip can stand upright.

[0017] The front end of the presser foot plate 2 extends upward to form an extension plate 9. The abutment frame 8 is a rod. One end of the rod is fixed or integrally set on the blocking wall 6, and the other end is fixed or integrally set on the extension plate 9. The blocking wall 6 and the extension plate 9 can form two support points, which makes it easy for the rod to overlap above. Of course, the abutment frame 8 can also be omitted. In this case, the position of the extension plate 9 is chamfered and polished to form an arc surface. This method can increase the visible area above the presser foot plate 2 and reduce obstruction.

[0018] The presser foot plate 2 is also provided with a cotton core hole 10. The cotton core rope can be added through the cotton core hole 10, which can make the binding strip more three-dimensional when sewing. Of course, the cotton core hole 10 can also be made of a coil. The coil is set above the presser foot plate 2 and has an extension arm. One end of the extension arm is fixed to the coil, and the other end extends to be fixed on the presser foot plate 2. Of course, the cotton core hole 10 can also be opened on the presser foot plate 2 and extend through the presser foot plate 2 to the outlet end of the wrapping hole 3.
