Technical Field

[0001] This utility model relates to the field of shoe upper processing, specifically a rotary switch auxiliary presser foot. Background Technology

[0002] The presence of webbing on the upper refers to the inclusion or addition of webbing elements on the shoe's upper. Webbing is typically made from various fibrous materials such as cotton, nylon, and polyester through a weaving process. It has a certain width and length and can be used for decoration, reinforcement, or to provide functionality such as increasing breathability and support. In shoe uppers, webbing can be cleverly integrated to enhance the shoe's visual appeal, improve wearing comfort, or meet specific athletic needs.

[0003] In the sewing of shoe uppers, some uppers incorporate webbing. However, during sewing, the webbing, due to its material, thickness, or position, often obstructs the normal movement of the presser foot. Traditional sewing methods are difficult to handle, requiring the use of high-speed single-stitch sewing, which leads to reduced efficiency, increased costs, and may also affect the sewing quality and shoe quality, becoming a production bottleneck. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a rotary switch auxiliary presser foot to solve the technical problem that the webbing of the shoe upper blocks the normal movement of the presser foot during the sewing process, resulting in low efficiency and increased cost of traditional sewing methods, and may affect the sewing quality and shoe quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary switch auxiliary presser foot, comprising a first template and a second template, the second template comprising a rotating plate, the top of the rotating plate having shoe-shaped grooves on both sides, and a presser foot mechanism being provided in the middle of the top of the rotating plate, the presser foot mechanism comprising a rotating seat, a presser foot piece being mounted on the rotating seat, and the presser foot piece being rotatably connected to the rotating plate through the rotating seat;

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A rotary switch auxiliary presser foot, such as Figures 1-4 As shown, the device includes a first template 1 and a second template 2. The second template 2 includes a rotating plate 201. The top of the rotating plate 201 has shoe trim grooves 202 on both sides. A presser foot mechanism 3 is set in the middle of the top of the rotating plate 201. The presser foot mechanism 3 includes a rotating seat 301. A presser foot piece 302 is installed on the rotating seat 301. The presser foot piece 302 is rotatably connected to the rotating plate 201 through the rotating seat 301. Two guide grooves 303 are opened on both sides of the presser foot piece 302. The guide grooves 303 are used to guide the shoe upper webbing. This setting allows the presser foot mechanism 3 to flexibly adjust its angle and position to adapt to the needs of different shoe uppers and webbing, improving the flexibility and adaptability of sewing. At the same time, the setting of the guide grooves 303 ensures that the shoe upper webbing is effectively guided during the sewing process, avoiding interference of the webbing with the sewing path, thereby ensuring the quality and precision of sewing.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The first template 1 includes a base plate 101. The top two sides of the base plate 101 are provided with shoe panel grooves 102, which are used to place the shoe upper. The shoe panel grooves 102 provide a stable platform for placing the shoe upper, ensuring the flatness and stability of the shoe upper during the sewing process. This setting helps to reduce the movement or deformation of the shoe upper during the sewing process, thereby improving the sewing accuracy and the overall quality of the shoe.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The top of the shoe panel groove 102 is provided with two positioning pins 103. The positioning pins 103 are used to fix the shoe upper. The positioning pins 103 can effectively fix the shoe upper and prevent it from moving or shifting during the sewing process. This setting not only improves the accuracy and consistency of sewing, but also reduces the error and scrap rate caused by the movement of the shoe upper, thereby reducing production costs.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The base plate 101 has a rotating shaft frame 104 on both rear ends. The inner side of the rotating shaft frame 104 is connected to the rotating plate 201 through a damping rotating shaft 203, which realizes a stable and flexible connection between the rotating plate 201 and the base plate 101. The damping rotating shaft 203 provides appropriate resistance, so that the rotating plate 201 can remain stable when rotating and will not easily shake due to external force. This helps to maintain the stability and accuracy of the presser foot mechanism 3 during the sewing process and improves the quality and efficiency of sewing.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 There are two shoe ornament slots 202, which are mirror images of each other along the central axis of the rotating plate 201. The mirror image arrangement of the two shoe ornament slots 202 allows two shoe ornaments to be placed at the same time during the sewing process, which improves the sewing efficiency. At the same time, this arrangement also helps to maintain the symmetry and consistency of the shoe ornaments during the sewing process, which enhances the aesthetics and overall quality of the shoes.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The first template 1 and the second template 2 are both made of PVC. PVC has good wear resistance, corrosion resistance and easy processing, which makes the rotary switch auxiliary presser foot have a long service life and good performance stability. The choice of this material not only reduces production costs, but also improves production efficiency, because PVC is easy to clean and maintain, reducing downtime caused by material problems.

[0036] The implementation principle of this utility model is as follows: First, the shoe upper is placed in the shoe panel groove 102 on the top of the base plate 101 of the first template 1. The shoe panel groove is set so that the shoe upper can be placed stably, providing a basis for subsequent sewing operations. The shoe upper is fixed to the top of the shoe panel groove 102 using positioning nails 103. The positioning nails ensure that the shoe upper will not move or shift during the sewing process, ensuring the accuracy and consistency of the sewing.

[0037] Then, rotate the rotating plate 201 and fasten it to the base plate 101. At this time, the shoe upper should be sandwiched between the rotating plate and the base plate, and the positioning pins should ensure that the shoe upper will not move. Place the shoe ornament into the shoe ornament groove 202 at the top of the rotating plate 201. The shoe ornament groove should be designed to ensure that the shoe ornament can be placed stably and to facilitate sewing with the shoe upper. After pressing, make the presser foot 302 fit tightly against the shoe upper. At the same time, the guide groove 303 should ensure that if the webbing is pushed open, it will not obstruct the normal movement of the presser foot.

[0038] After the preset sewing path is completed, lift the presser foot mechanism 3 to remove the sewn shoe from the first template 1 and the second template 2.

[0039] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
