Description

Technical Field

[0001] The utility model relates to the technical field of sewing, and particularly relates to an auxiliary tool for processing the arc edge of a light fabric. Background Art

[0002] Light fabrics generally refer to fabrics that are more breathable and lighter than pure cotton materials. They generally have a certain degree of light transmittance, high softness, and are usually used to make summer clothes or clothes that need to outline the body curve to provide a comfortable and breathable or close-fitting wearing experience. Common light fabrics include, but are not limited to, gauze fabrics, silk fabrics, pure silk fabrics, or synthetic fiber fabrics such as nylon and polyester.

[0003] Due to the characteristics of light fabrics, they are also very suitable for use as decorations on clothes. Such decorations include clothing openings, such as the ruffled edges at the cuffs and hems, or decorative strips on the clothing surface. These decorations made of light fabrics can flutter irregularly to different degrees with the movements of the wearer, thereby creating a light effect for the clothing and also playing a role in modifying the body shape.

[0004] However, after the light fabric is cut into strip-shaped pieces, it is difficult to process its edges. In addition, with the upgrading of designs, there are also many design requirements that the long sides of these strip-shaped pieces are arcs. Even if the cutting of the pieces can be completed, it is difficult for inexperienced workers to process the arc edge binding in a short time. Often, the binding line cannot be completely parallel to the edge, and some even cause the thread to run off the piece, which leads to a high waste rate of the pieces, a reduction in work efficiency, a processing bottleneck, and an increase in costs.

[0022] The following further describes the present utility model in detail with reference to embodiments, but the protection scope of the present utility model is not limited thereto.

[0023] The present utility model relates to an auxiliary tool for processing the arc - shaped edge of a light and thin fabric. The processing auxiliary tool includes a number of diaphragm plates 1 arranged in a sequential cooperation. An associated component is provided between two adjacent diaphragm plates 1. Sewing holes 2 are provided in all the diaphragm plates 1, and at least one end of the sewing hole 2 is arc - shaped.

[0024] In the present utility model, after a number of diaphragm plates 1 associated by the associated component are unfolded, the sewing holes 2 they cooperate with simulate the arc - shaped edge to be processed section by section. With the positioning assistance of the associated component, sewing is completed at the sewing holes 2.

[0025] In the present utility model, at least the outer side edge of the sewing hole 2 is arc - shaped, and the central angle corresponding to the arc here is relatively small, which is convenient for fitting the arc - shaped edge to be processed. In fact, considering that the light and thin fabric is processed and the operation requirements are high, deburring or chamfering treatment should be carried out on the outer side edge and the corner of the sewing hole 2, generally smooth rounded corners or arc surfaces, to prevent damage to the light and thin fabric.

[0026] All the diaphragm plates 1 are hinged at one end, and the sewing holes 2 are provided at the other end of all the diaphragm plates 1.

[0027] The associated component includes an elastic wire harness (not shown in the figure) provided between two adjacent diaphragm plates 1.

[0028] One or more card slots 3 are provided on both sides of any diaphragm plate 1, and one or more support members 4 are detachably provided in cooperation with the card slots 3.

[0029] In the present utility model, considering the simulation of the arc - shaped edge, all the diaphragm plates 1 are hinged at one end and can be unfolded like a fan. The sewing holes 2 are provided at the other end of the diaphragm plates 1 for fitting the arc - shaped edge. In practical applications, when sewing a saw - tooth line or the like is required, multiple parallel and associated diaphragm plates 1 can also be provided, and the fitting of a rectangular sewing line can be achieved by adjusting the positions of the sewing holes 2. This is an easy - to - understand technical expansion for those skilled in the art.

[0030] In the present utility model, the arc-shaped edge may be irregular (non-regular circular arc). Therefore, the width of the die piece 1 can be relatively narrow, and the opening degree between every two adjacent die pieces 1 is not necessarily the same, so as to obtain the fitting of different arc-shaped edges. In this process, the opening degree between every two adjacent die pieces 1 can be from 0 to the maximum value. In order to ensure that the sewing holes 2 are in a complete arc shape when fully unfolded (maximum value), an elastic wire harness is arranged between two adjacent die pieces 1 to ensure that the basic order remains unchanged. At the same time, after the fitting of the arc-shaped edge is completed, by arranging a support member 4 between the clamping grooves 3 on the opposite sides of any two die pieces 1, the positioning of the position can be realized. The overall limit can be realized through the positioning of multiple support members 4. The clamping groove 3 can be one or more, and the structure of multiple clamping grooves 3 is more suitable for the application of complex arc-shaped edges. The support member 4 can be arranged according to the needs of those skilled in the art. Considering the relatively thin characteristic of the template itself, the support member 4 can also be made of a thin sheet material (but with a certain strength), and its two ends are respectively trimmed into a fork shape and positioned between two clamping grooves 3.

[0031] One end of the sewing hole 2 corresponding to each die piece 1 is connected to the die piece 1, and the other ends of all the sewing holes 2 are provided with hemming strips 5. A limiting member 6 is arranged between the hemming strips 5 corresponding to two adjacent die pieces 1. On the side of the sewing hole 2 corresponding to the first die piece 1 that faces away from the sewing holes 2 of other die pieces 1, a stop strip 7 is provided.

[0032] The limiting member 6 includes one first convex block 61 arranged on the side of the hemming strip 5 of the first die piece 1 that is opposite to the stop strip 7, one first convex block 61 on one side of each hemming strip 5 except the hemming strip 5 corresponding to the first die piece 1, and two second convex blocks 62 arranged on the other side. The distance between any first convex block 61 and the hinged end of all die pieces 1 is equal to the distance between the middle position of any group of two second convex blocks 62 and the hinged end of all die pieces 1, and the maximum outer diameter of the first convex block 61 is less than the distance between the two second convex blocks 62.

[0033] On both sides of the back surface of any die piece 1, sliding strips 8 are provided, and any sliding strip 8 corresponds to the side part of the sewing hole 2 of the die piece 1.

[0034] On the back surface of the die piece 1 that cooperates with the sliding strip 8, a sliding groove 9 is provided.

[0035] A gasket 10 is detachably arranged at the bottom of the die piece 1 that cooperates with the limiting member 6.

[0036] In the present utility model, one end of the sewing hole 2 is correspondingly connected to the die plate 1, and a hemming strip 5 is provided at the other end. Since the hemming strip 5 is at a relatively far distance from the hinged end of the die plate 1, the length of each hemming strip 5 is actually slightly larger than the width of the die plate 1. That is, when all the die plates 1 are unfolded to the maximum (generally not unfolded to the maximum), all the hemming strips 5 are still connected in sequence. Therefore, in order to ensure the convenience of adjustment, a limiting member 6 is provided between the hemming strips 5 corresponding to two adjacent die plates 1. Through the setting of the limiting member 6, the hemming strips 5 are interconnected and will not break. Furthermore, a stop strip 7 can be provided at the sewing hole 2 corresponding to the first die plate 1, so that the hemming strip 5 is connected to the die plate 1, and the bottom of the sewing hole 2 is disconnected, which can be used for feeding and discharging, and the sewing hole 2 is complete.

[0037] In the present utility model, specifically, one first convex block 61 and two second convex blocks 62 provided on both sides of the hemming strip 5 cooperate with each other. The first convex block 61 of the previous hemming strip 5 is blocked by the second convex blocks 62 of the next hemming strip 5 and will not come off. In practical applications, the first convex block 61 is arranged at the middle position between the two second convex blocks 62 and its outer diameter is larger and not enough to pass through the two grouped second convex blocks 62. Considering that the limiting member 6 has a certain height, for the convenience of processing, a gasket 10 is detachably arranged at the bottom of the die plate 1 to facilitate leveling.

[0038] In the present utility model, considering that during the process of unfolding the die plate 1 for fitting the arc edge, the die plate 1 and the hemming strip 5 must be consistent. Therefore, sliding strips 8 are provided on both sides of the back surface of the die plate 1. During adjustment, the sliding strips 8 correspond to the two ends of the corresponding hemming strip 5 and retract after the adjustment is completed. In order to facilitate the protrusion and retraction of the sliding strips 8, a sliding groove 9 is provided on the back surface of the die plate 1 to cooperate with it. In the specific implementation process, double-layer circular sliding pieces 11 are provided on the sliding strips 8. The centers of the double-layer circular sliding pieces 11 are connected and the edges are not connected. The edges of the double-layer circular sliding pieces 11 cooperate with the sliding holes 12 opened on the sliding groove 9 to play the role of sliders.

[0039] Damping members are provided at the hinged ends of all the die plates 1.

[0040] In the present utility model, in order to further reduce the edge offset after completing the arc edge fitting, damping members can be provided at the hinged ends of the die plates 1 to increase the resistance of their rotation.

Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the present utility model.

[0042] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
