Description

Technical Field

[0001] This invention relates to the field of garment processing, and in particular to a herringbone V-neck sweetheart neck assembly. Background Technology

[0002] Currently, when processing V-neck sweetheart garments, most manufacturers use conventional flat sewing machines, manually backstitching forward and backward, or use electronic flat sewing machines with pre-set backstitching parameters and electronically driven backstitching. These machines are equipped with conventional flat sewing presser feet, needle plates, and teeth, requiring operators to coordinate foot movements to repeatedly sew forward and backward.

[0003] However, this method requires operators to continuously align the upper and lower layers of fabric, demanding a relatively high level of sewing skill to complete successfully, thus increasing labor costs. Furthermore, the feed-by-the-tooth method is less effective for shorter front-to-back sewing distances and uneven seams, often resulting in misalignment of the upper and lower layers. This leads to a series of quality issues such as asymmetry in the V-neck, pleats, and skewing, further impacting production efficiency. Such quality problems are generally unacceptable in the garment manufacturing industry. Summary of the Invention

[0004] To solve at least one of the above-mentioned technical problems, the present invention provides a herringbone-stitched V-neck sweetheart assembly, the technical solution of which is as follows:

[0005] This invention provides a herringbone V-neck gown assembly, comprising a presser foot structure and a needle plate structure. The presser foot structure includes an installation unit and a limiting unit, connected to the limiting unit. The installation unit is vertically positioned, while the limiting unit is horizontally positioned. The installation unit can be mounted on the sewing machine head. The limiting unit has a limiting hole through which the sewing needle can pass to the garment. The needle plate structure is mounted on the base of the sewing machine, horizontally positioned below the presser foot structure. The needle plate structure has a through hole and a stop strip. The through hole is below the limiting hole and corresponds in shape to it. The stop strip is located at the edge of the through hole and is arc-shaped. The middle of the stop strip extends away from the through hole. When the lower end of the garment's neckline is within the range of the stop strip, the lower end of the garment's neckline covers the through hole.

[0006] The embodiments of the present invention have at least the following beneficial effects: In the present invention, the lower end of the neckline of the garment is placed within the range of the retaining strip to prevent the garment from shifting during the sewing process. The part to be sewn is above the through hole. During the sewing process, the presser foot structure descends, so that the limiting unit and the needle plate structure clamp the lower end of the neckline of the garment, and the fold line of the garment is flush with the edge of the retaining strip body, which facilitates the positioning of the garment, avoids misalignment of the upper and lower layers of fabric, and avoids quality problems of the heart-shaped structure. The needle passes through the lower end of the neckline of the garment along the limiting hole and enters the through hole. This process is repeated. During the movement of the needle, there is less obstruction, which makes it easier for the staff to observe. The sewing of the heart-shaped structure can be completed with one step, without the need for manual backstitching.

[0007] In some embodiments of the present invention, the herringbone V-neck sweetheart assembly further includes a guarding assembly. The guarding assembly includes a fixing plate and a guarding body. The fixing plate is disposed adjacent to the needle plate structure. The guarding body is disposed on the fixing plate. The edge of the guarding body is straight. When the lower end of the neckline of the garment is within the range of the guarding strip, the fold line of the garment is flush with the edge of the guarding body.

[0008] In some embodiments of the present invention, the edge-blocking body is provided with an adjustment hole, the adjustment hole extending from the end of the edge-blocking body to the middle of the edge-blocking body, and a positioning component is provided on the fixing plate, the positioning component passing through the adjustment hole and connecting to the fixing plate.

[0009] In some embodiments of the present invention, the limiting hole is strip-shaped, and a first rounded corner is provided at the corner inside the limiting hole.

[0010] In some embodiments of the present invention, the via is strip-shaped, and a second rounded corner is provided at the corner inside the via. The two ends of the baffle are respectively close to the two ends of the via.

[0011] In some embodiments of the present invention, the needle plate structure is provided with a plurality of hollowed-out portions, each hollowed-out portion is arranged around the through hole, and each hollowed-out portion is arranged in a rectangular array, and a baffle is provided near the hollowed-out portion of the garment.

[0012] In some embodiments of the present invention, the baffle is made of stainless steel and is connected to the needle plate structure by welding.

[0013] In some embodiments of the present invention, the herringbone V-neck sweetheart assembly further includes an operation panel, which is electrically connected to a sewing machine and on which the sewing path and sewing size can be set.

[0027] This section will combine Figures 1 to 5Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention 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, and therefore should not be construed as a limitation of the invention. Features defined with "first" and "second" are used to distinguish feature names and do not have special meanings. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] This invention provides a herringbone V-neck gore assembly, which includes a presser foot structure 101 and a needle plate structure 201. The presser foot structure 101 and the needle plate structure 201 are relatively independent. When sewing the gore structure, the presser foot structure 101 and the needle plate structure 201 cooperate with each other to work.

[0031] like Figure 2 As shown, the presser foot structure 101 includes an installation unit 102 and a limiting unit 103. The installation unit 102 is used to fix the presser foot structure 101 to the head of the sewing machine. The limiting unit 103 is used to limit the travel path of the needle. At the same time, the limiting unit 103 can also press the part of the garment to be sewn firmly to prevent the garment from shifting during the sewing process, which would result in poor sewing quality.

[0032] Furthermore, the mounting unit 102 is connected to the limiting unit 103. The mounting unit 102 is vertically positioned, and the limiting unit 103 is horizontally positioned, meaning the presser foot structure 101 has an overall L-shaped structure. Alternatively, the mounting unit 102 and the limiting unit 103 are at a certain angle to adapt to specific sewing machines, ensuring that the limiting unit 103 remains horizontal. The mounting unit 102 and the limiting unit 103 are either integrally molded or manufactured separately and then fixedly connected, ensuring stable relative positions between them.

[0033] Specifically, the limiting unit 103 is provided with a limiting hole 104. The sewing needle on the sewing machine passes through the limiting hole 104 to reach the garment and then sew it. To ensure sewing quality and strength, the sewing needle needs to undergo a certain degree of horizontal displacement during the sewing process, thereby continuously driving the thread through the area to be sewn on the garment. Therefore, the limiting hole 104 has a certain area. Since the presser foot structure 101 is fixed to the sewing machine head, the movement of the sewing needle relative to the sewing machine head is equivalent to the movement of the sewing needle relative to the limiting unit 103. Furthermore, during operation, the sewing needle undergoes horizontal displacement within the range of the limiting hole 104. When the position of the garment remains stable, a sewing line is set within the range of the limiting hole 104, allowing the worker to complete the sewing of the heart-shaped structure with a single step. This simplifies the workflow and reduces labor costs.

[0034] In some examples, the limiting hole 104 is strip-shaped and is set along the width direction of the sewing machine. That is, the sewing line can be set longer in the width direction of the sewing machine and shorter in the length direction of the sewing machine. The limiting hole 104 has a first rounded corner 105 at the corner.

[0035] In some examples, the mounting unit 102 is provided with a second mounting hole 106 through which fasteners can be connected to the sewing machine head to ensure the relative position of the presser foot structure 101 and the sewing machine head is stable.

[0036] In some examples, the distance from the edge of the limiting hole 104 to the end of the limiting unit 103 is about 2 mm, and a semi-circular flat opening is formed. The presser foot structure 101 does not have an additional solid structure at the position of the limiting hole 104, so as to avoid obstructing the operator's view too much and make it easier for the operator to observe whether there is any abnormality in the sewing machine's operation.

[0037] like Figure 1 , Figure 3As shown, the needle plate structure 201 is disposed on the base of the sewing machine. The needle plate structure 201 is horizontally positioned to facilitate the flat placement of the garment on the needle plate structure 201. Furthermore, the needle plate structure 201 is located below the presser foot structure 101. During operation, the presser foot descends and gradually approaches the needle plate structure 201. The horizontally positioned needle plate structure 201 and the horizontally positioned limiting unit 103 can clamp the garment, thereby preventing unnecessary displacement of the garment during the sewing process.

[0038] During the sewing process, since the needle needs to penetrate the garment, a through hole 202 is provided on the needle plate structure 201. With the garment held between the needle plate structure 201 and the limiting unit 103, the needle passes through the limiting hole 104, the garment, and the through hole 202 in sequence, thereby completing the sewing. It can be understood that the through hole 202 is located below the limiting hole 104, and the shape of the through hole 202 corresponds to that of the limiting hole 104.

[0039] Furthermore, a stop strip 203 is provided on the needle plate structure 201. The stop strip 203 forms a semi-closed area on the needle plate structure 201, so that the lower end of the neckline of the garment can be placed in the semi-closed area, so that the garment has a relatively stable position before the sewing operation, so that the sewing position is uniform, ensuring that the shape of the heart-shaped structure of the same batch of garments is uniform, and improving product quality.

[0040] The retaining strip 203 is positioned at the edge of the through hole 202. Since the lower neckline of the garment extends slightly outward after folding, the retaining strip 203 is arc-shaped, with its center extending away from the through hole 202 to accommodate this extension. Understandably, when the lower neckline of the garment is positioned within the area of ​​the retaining strip 203, the lower neckline covers the through hole 202, preparing for the sewing process.

[0041] In some examples, the baffle 203 is welded from a stainless steel sheet about 0.5 mm thick, with a distance of about 8 mm between the two ends, a depth of about 4 mm in the arc, and a height of about 1 mm.

[0042] In some examples, the through hole 202 is strip-shaped and is set along the width direction of the sewing machine to adapt to the shape of the limiting hole 104. At the same time, a second rounded corner 204 is provided at the corner of the inside of the through hole 202. It can be understood that the two ends of the stop strip 203 are respectively set near the two ends of the through hole 202, and the stop strip 203 is symmetrically arranged with the through hole 202 as the center.

[0043] In some examples, the needle plate structure 201 has several perforations 205, each perforation 205 surrounding the through hole 202, arranged in a rectangular array. In a conventional sewing machine, the perforations 205 allow the teeth on the gripper plate to pass through, and the garment is displaced by the push of the teeth, thus forming the sewing path. During the sewing of the V-shaped hem, the garment does not move, and the needle plate structure 201 has a stop bar 203 for positioning. The gripper plate would obstruct the sewing process of the V-shaped hem. Therefore, the conventional gripper plate is removed, and the perforations 205 near the garment are sealed.

[0044] Specifically, a baffle 206 is provided near the openwork section 205 of the garment. The baffle 206 is made of stainless steel to improve durability, and the baffle 206 is connected to the needle plate structure 201 by welding to seal the openwork section 205.

[0045] In some examples, the needle plate structure 201 is provided with a first mounting hole 207, through which fasteners can be connected to the base of the sewing machine to ensure the relative position of the needle plate structure 201 and the base of the sewing machine is stable, and to prevent the needle plate structure 201 from shifting during sewing and affecting product quality.

[0046] like Figure 4 , Figure 5 As shown, the herringbone V-neck sweetheart neck assembly also includes a guard assembly 301. The guard assembly 301 includes a fixing plate 302 and a guard body 303. The fixing plate 302 is mounted on the base of the sewing machine and is adjacent to the needle plate structure 201. The guard body 303 is mounted on the fixing plate 302. The guard body 303 facilitates the worker in positioning the fold line of the garment, thereby further defining the position of the garment before the sewing process and ensuring a uniform shape of the sweetheart neck structure. Furthermore, the edge of the guard body 303 is straight, allowing the worker to align the straight fold line of the garment with the edge of the guard body 303.

[0047] In some examples, the edge-stop body 303 is movably connected to the fixing plate 302. The edge-stop body 303 has an adjustment hole 304, which is strip-shaped and extends from one end to the middle of the edge-stop body 303. The fixing plate 302 has a positioning component 305, which is threadedly connected to the fixing plate 302 and passes through the adjustment hole 304. When the position of the edge-stop body 303 needs to be adjusted, the positioning component 305 is unscrewed, allowing the edge-stop body 303 to move or rotate. During this movement or rotation, the positioning component 305 remains within the range of the adjustment hole 304, and its relative position to the adjustment hole 304 changes. After the position of the edge-stop body 303 is adjusted, the positioning component 305 is screwed in to position the edge-stop body 303.

[0048] In some examples, the fixing plate 302 is also provided with a first mounting hole 207. Fasteners can be connected to the base of the sewing machine by passing through the first mounting hole 207 to ensure that the relative position of the fixing plate 302 and the base of the sewing machine is stable, and to prevent the fixing plate 302 from shifting during the sewing process, which would affect the positioning of the garment.

[0049] In some examples, the herringbone V-neck sweetheart assembly also includes an operation panel that is electrically connected to the sewing machine. Adjusting the parameters on the operation panel allows setting the sewing path and sewing size, ensuring that the sewing path is reasonable while preventing it from exceeding the range of the limiting hole 104.
