Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of shoe ear false thread processing auxiliary devices, specifically a device capable of quickly positioning shoe ear before processing shoe ear false thread. BACKGROUND

[0002] In the design process of shoes, false thread is a more commonly used design element, and the false thread is a single-layer vehicle line sewn on the surface of the shoe body, which is not sewn with the inner lining of the shoe body and does not affect the performance of the shoe. Therefore, the false thread is often used as a decorative line to increase the personalization of the shoe style.

[0003] In the shoemaking process, the false thread is usually sewn using a single needle machine, but the single needle machine needs to be operated manually during the sewing process, which is low in efficiency and difficult to operate, and the operator needs to be trained before they can operate. Therefore, shoe manufacturers have gradually begun to try to use pattern machines to sew false threads. Before using the pattern machine to sew, the shoe-making material needs to be positioned to ensure that the false thread sewn by the pattern machine is located at the specified position on the shoe-making material.

[0004] Currently, the method for positioning the shoe-making material is usually achieved by installing a template on the pattern machine. Specifically, the template has a hollow part for positioning the cloth and sewing the pattern machine thread. By aligning the edge of the hollow part with the edge of the shoe-making material or the auxiliary positioning line drawn on the shoe-making material, the position of the shoe-making material is determined, and the template is pressed on the shoe-making material to complete the positioning of the shoe-making material. However, this positioning method requires full alignment and positioning of each shoe-making material before processing, which is relatively complicated and low in positioning efficiency. SUMMARY

[0005] To solve the above problems in the prior art, the present utility model aims to provide a positioning device for shoe ear false thread processing to quickly position the shoe ear.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present utility model is as follows:

[0007] A positioning device for shoe ear false thread processing includes a positioning template and a pressing plate used in conjunction with the positioning template to fix the shoe ear to be processed. The positioning template has a sewing groove, and the positioning template is fixed with a positioning block that matches the shape of the opening on the shoe ear to be processed.

[0008] It should be noted that the shape of the positioning block is the same as that of the opening on the shoe ear to be processed, and the position of the sewing groove corresponds to the pre-set false thread processing position of the shoe ear to be processed.

[0009] As a limitation of this utility model, the sewing groove is an arc-shaped through hole, and the shape of the arc-shaped through hole is adapted to the sewing path of the shoe ear false thread.

[0010] As a further limitation of this utility model, one end of the pressure plate is an arc-shaped end face, and the curvature of the arc-shaped end face is the same as the curvature of the sewing groove.

[0011] As another limitation of this utility model, a pressure block is also fixed on the side of the pressure plate facing the positioning template.

[0012] As a further limitation of this utility model, the material of the pressing block is rubber.

[0013] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0014] (1) This utility model designs a device that can quickly position the shoe ear. Specifically, by setting a positioning block on the positioning template with the same shape as the notch on the shoe ear, the positioning block can be inserted into the notch on the shoe ear to quickly determine the position of the shoe ear. ... At the same time, by setting a pressure plate that works with the positioning template, after the position of the shoe ear is determined, the pressure plate and the positioning template can clamp the shoe ear to fix it.

[0015] (2) In this utility model, the positioning template is provided with a sewing groove, and the curvature of the sewing groove is adapted to the sewing path of the shoe ear false thread. During the sewing process, the sewing needle can avoid colliding with the positioning template, thus ensuring the quality of sewing.

[0016] (3) In this utility model, the end of the pressure plate near the sewing groove is an arc-shaped end face, and the curvature of the arc-shaped end face is the same as that of the sewing groove, so that the pressure plate can fix the shoe ear with the largest area without interfering with the sewing path, so as to achieve a better fixing effect.

[0017] (4) In this utility model, a rubber block is also fixed on the pressure plate. The block can shorten the distance between the pressure plate and the positioning template, so that the pressure plate can better clamp the shoe ear between the pressure plate and the positioning template after pressing down. At the same time, the block is made of rubber, which can prevent damage to the shoe ear during the clamping process.

[0018] In summary, this invention can quickly position shoe ears and is suitable for sewing fake threads on shoe ears. Attached Figure Description

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0025] This embodiment discloses a positioning device for processing fake stitching on shoe lugs, such as... Figure 1 and Figure 2 As shown, the device includes a positioning template 1 and a pressure plate 4. The positioning template 1 has a sewing groove 2 and a positioning block 3 fixedly mounted on it. The sewing groove 2 is an arc-shaped through hole, the curvature of which matches the sewing path of the false thread on the shoe ear 6, ensuring that the sewing needle will not contact the positioning template 1 during sewing. The shape of the positioning block 3 is the same as the shape of the notch on the shoe ear 6 to be processed. The positioning block 3 is placed next to the sewing groove 2 to ensure that after the notch in the shoe ear 6 is aligned with the positioning block 3 and placed on the positioning template 1, the position of the false thread to be sewn on the shoe ear 6 is exactly within the range of the sewing groove 2. In actual use, simply align the notch on the shoe ear 6 with the positioning block 3 and place the shoe ear 6 on the positioning template 1 so that the positioning block 3 fits tightly with the notch to determine the position of the shoe ear 6.

[0026] The pressure plate 4 is a flat metal plate, one end of which has an arc-shaped end face. The arc of the arc-shaped end face is the same as the arc of the sewing groove 2. For example... Figure 2 As shown, when the pressure plate 4 is in use, a pressure block 5 is also fixed on the side facing the positioning template 1. The pressure block 5 is a long strip of rubber block with an arc. The pressure block 5 is located at one end of the arc-shaped end face of the pressure plate 4. The arc of the pressure block 5 is the same as the arc of the arc-shaped end face of the pressure plate 4, and the height of the pressure block 5 is greater than the height of the positioning block 3.

[0027] When using this embodiment, as Figure 3As shown, first, fix the positioning template 1 on the moving part of the pattern sewing machine, and adjust the positions of the positioning template 1 and the needle of the pattern sewing machine to ensure that after the shoe ear 6 is placed on the positioning template 1 and positioned, the position of the needle is the origin of the set sewing trajectory. Then, fix the pressure plate 4 on the pressing part of the pattern sewing machine, so that one end of the arc-shaped end face of the pressure plate 4 faces the sewing groove 2 on the positioning template 1, and adjust the position of the pressure plate 4 so that the projection of the arc-shaped end face of the pressure plate 4 on the positioning template 1 coincides with the edge of the sewing groove 2 near the pressure plate 4. After the adjustment is completed, the shoe ear 6 can be placed on the positioning template 1, and the notch on the shoe ear 6 is aligned with the positioning block 3. Then, proceed as follows. Figure 3 Place the notch on positioning block 3 in the direction indicated by the middle arrow, and then you can start sewing the dummy thread.
