[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a hemming sewing aid. Figure 1 The auxiliary device includes a connecting part 1, a pull cylinder body 2, a guide part 5, a supporting plate 7 and a pressing plate 8. The edging cloth passes through the pull cylinder body 2 and is used to fold the edging cloth neatly. The guide part 5 is fixedly installed on the pull cylinder body 2 and is used to change the feeding direction of the edging cloth. The supporting plate 7 is fixedly installed on the pull cylinder body 2 and is used to support the cloth. The pressing plate 8 is also fixedly installed on the pull cylinder body 2 and is used to flatten the edging cloth. The connecting part 1 is also fixedly installed on the pull cylinder body 2 and is used to install the pull cylinder body 2 on the sewing machine.

[0033] refer to Figure 1 The auxiliary device is a tool to assist the sewing machine in sewing hemming, so the auxiliary device needs to be installed on the sewing machine table and adjacent to the sewing machine needle, so a connecting part 1 is provided. Specifically, the connecting part 1 is a strip-shaped structure, which is fixedly installed on the outer cylinder 21 along the extension direction of the pull cylinder body 2. A base is provided at the corresponding position of the sewing machine table, and a mounting hole is provided on the base. The connecting part 1 can be detachably installed on the sewing machine table by plugging and unplugging. Workers can choose whether to install the auxiliary device according to their needs, which improves the practicality of the auxiliary device.

[0034] refer to Figure 2 If the binding cloth is only folded symmetrically, wrapped and sewn on the edge of the mat, the edge of the binding cloth is exposed to the outside, and the thread may be detached after long-term use. If the thread is seriously detached, the binding cloth may fall off the mat, making the overall quality of the mat poor. Therefore, a pull tube body 2 is provided, and the pull tube body 2 includes an outer tube 21 and an inner tube 22. The outer tube 21 is installed on the outside of the inner tube 22. Specifically, the outer tube 21 is a long strip structure formed by bending a sheet, and the cross-section of the long strip structure is U-shaped. The inside of the outer tube 21 is connected to the outside, and the edges of the two U-shaped sides of the outer tube 21 are connected to the outside. The edge of the inner tube 21 is bent toward the inside of the tube to form a bending portion 211, which is not in contact with the tube wall, and a gap is left between the inner tube 21 and the tube wall for accommodating the inner tube 22; the inner tube 22 is installed inside the outer tube 21. Specifically, the structure of the inner tube 22 is similar to that of the outer tube 21, and is also a long strip structure formed by bending a sheet, and the cross-section of the long strip is U-shaped. The volume of the inner tube 22 is slightly smaller than that of the outer tube 21, and it is installed inside the outer tube 21, and the bending portion 211 contains the edge of the inner tube 22 in the bending portion 211, and a gap is left between the outer tube 21 and the inner tube 22 for the hemming cloth to pass through.

[0035] The pull tube body 2 also has a feed end 3 and a discharge end 4. The inner tube 22 and the outer tube 21 are fixedly connected at a point on the feed end 3 by spot welding, and the rest of the inner tube 22 is separated from the outer tube 21 by a gap. To facilitate the folding of the edging cloth and the inward folding of the edge of the edging cloth, the U-shaped opening of the pull tube body 2 from the feed end 3 to the discharge end 4 gradually decreases, and the length of the two U-shaped sides gradually decreases. This arrangement allows the folding of the edging cloth and the inward folding of the edge of the edging cloth to be gradually completed in the process of the edging cloth passing from the feed end 3 to the discharge end 4, which is helpful for the folding of the edging cloth. The outer tube 21 and the inner tube 22 fold the edging cloth symmetrically, and the bending portion 211 folds the edge of the edging cloth again, so that when the edging cloth is sewn on the mat, the width of the edging cloth is consistent and the edge of the edging cloth is smooth, which reduces the possibility of the edging quality being affected by human factors and improves the edging quality of the mat.

[0036] refer to Figure 3The edging cloth is inserted into the gap of the pull tube body 2. Since the gap is relatively closed, the state of the edging cloth in the gap cannot be seen from the outside. If the edging cloth gets stuck in the gap, the worker cannot adjust it from the outside, which is inconvenient to use. Therefore, a long hole 221 is opened on the inner tube 22. Specifically, the long hole 221 runs through the wall of the inner tube 22. The long hole 221 connects the gap with the outside. When the edging cloth is inserted into the gap, the state of the edging cloth can be seen from the U-shaped opening of the pull tube body 2, which is beneficial for the worker to adjust the edging cloth; to further facilitate the adjustment of the edging cloth, a plurality of long holes 221 can be provided, such as two, three or more than three. In the present embodiment, three long holes 221 are provided. The long holes 221 are arranged at intervals and evenly on the wall of the inner tube 22, which is convenient for observing the edging cloth at any position and convenient for adjustment, so that the folding of the edging cloth is smoother.

[0037] Referring to the figure, the feeding of the edging cloth requires pulling the edging cloth from the cloth shaft into the auxiliary device on the sewing machine table. If the edging cloth and the cloth mat are fed in the same direction, the pulled out edging cloth may hinder the worker's arm operation. Therefore, a guide part 5 is also provided. Specifically, the guide part 5 is a plate-like structure, which is fixedly mounted on the edge of the feed end 3 of the outer cylinder 21, and the guide part 5 is perpendicular to the extension direction of the pull cylinder body 2. Therefore, the cloth shaft of the edging cloth can be set next to the sewing machine, and the feeding direction of the edging cloth is perpendicular to the feeding direction of the cloth mat. Such a setting reduces the possibility of the pulled out edging cloth interfering with the worker's arm, and the edging cloth is guided and reversed at the connection between the guide part 5 and the outer cylinder 21, and is fed in from the feed end 3 and sent out from the discharge end 4 synchronously with the cloth mat.

[0038] refer to Figure 3 The edging cloth may move up and down when passing through the guide part 5. Then, when the edging cloth passes through the feed end 3, it cannot be well folded in the pull tube body 2. Therefore, a limiting strip 6 is fixedly installed on the guide part 5. Specifically, the limiting strip 6 is a long sheet structure. The two ends of the limiting strip 6 are respectively fixedly connected to the guide part 5. The length of the limiting strip 6 is consistent with the width of the edging cloth. There is a gap between the limiting strip 6 and the guide part 5 for the edging cloth to pass through. The limiting strip 6 limits the movement of the edging on the guide part 5, so that the edging cloth can pass through the feed end 3 more smoothly, and the limiting strip 6 limits the edging cloth from detaching from the limiting part, so that the edging cloth can be fed stably and continuously.

[0039] refer to Figure 3The edging cloth is first passed through the pull tube body 2 and folded, and then the cloth mat can be loaded. When the edging cloth and the cloth mat are sent out from the discharge end 4 together, sewing is carried out. However, since the pull tube body 2 has a certain thickness in structure, when the cloth mat passes through the U-shaped opening on the pull tube body 2, the cloth mat on the sewing machine table and the cloth mat in the pull tube body 2 are not at the same height level. The height difference is not conducive to leveling the cloth mat, and it is not convenient to sew the edging cloth. Therefore, a supporting plate 7 is extended outward from the U-shaped opening of the pull tube body 2. The supporting plate 7 is fixedly mounted on the inner side wall of the inner tube 22 and the bending portion 211 of the outer tube 21. When the cloth mat passes through the pull tube body 2, the cloth mat is supported by the supporting plate 7, so that the cloth mat near the sewing is at the same height level, which is conducive to leveling the cloth mat, facilitates sewing of the sewing machine, and improves the sewing quality at the same time.

[0040] Replay Figure 2 It should be noted that when the pull cylinder body 2 is installed on the sewing machine table, the pull cylinder body 2 is horizontally arranged on the sewing machine table, the U-shaped opening of the pull cylinder body 2 faces the outside of the sewing machine, and the feeding end 3 of the pull cylinder body 2 faces the worker in front of the sewing machine. The setting direction of the pull cylinder body 2 is consistent with the feeding direction of the cloth mat, and the edging cloth passes through the gap between the outer cylinder 21 and the inner cylinder 22, and the cloth mat passes through the U-shaped opening on the inner side of the pull cylinder body 2 to realize that the edging cloth is wrapped on both sides of the edge of the cloth mat, and the cloth mat and the edging cloth move synchronously toward the discharge end 4 of the pull cylinder body 2, and the edging cloth delivered from the discharge end 4 is wrapped on the cloth mat.

[0041] refer to Figure 2 The edging cloth sent out from the discharge end 4 of the pull tube body 2 is folded in half, and the edge of the edging cloth is also folded inward. Therefore, the edging cloth will be warped upward relative to the cloth mat, and cannot fit flatly with the cloth mat, which makes it inconvenient to sew the edging cloth on the cloth mat. Therefore, a pressing plate 8 is also provided. Specifically, the pressing plate 8 is a plate structure, which is fixedly mounted on the discharge end 4 of the outer tube 21, and is used to press down the warped edging cloth, and the pressing plate 8 is located next to the sewing machine needle, so that the flattened edging cloth can be directly sewn onto the cloth mat.

[0042] The implementation principle of the hemming sewing assistant of the embodiment of the present application is as follows: the hemming cloth is guided by the guide part 5 and enters the gap inside the pull tube body 2 from the feed end 3 of the pull tube body 2, the pull tube body 2 symmetrically folds the hemming cloth in half, folds the edge of the hemming cloth inward, and the hemming cloth is delivered from the discharge end 4 of the pull tube body 2, and the cloth mat simultaneously passes through the inner side of the pull tube body 2 and is delivered from the discharge end 4, then the hemming cloth delivered from the discharge end 4 is folded in half and wrapped around the edge of the cloth mat, and sewing can be directly performed.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
