Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fabric sewing positioning technology, specifically relating to a fabric alignment device for garment production. Background Technology
[0002] In modern garment production, fabric alignment is a crucial link between cutting and sewing, and its technical level directly impacts the quality of finished garments and production efficiency. As consumers' demands for personalized and refined clothing continue to rise, the technical bottlenecks of fabric alignment devices are becoming increasingly apparent when dealing with diverse fabrics and complex designs.
[0003] As exemplified by the existing patent CN217378217U, entitled "A Sewing Edge Alignment Device for Garments," while it can adjust and extend the positioning distance, it has revealed numerous problems in practical applications. Structurally, its fixed height adjustment mechanism struggles to adapt to the alignment requirements of fabrics of varying thicknesses. Garment production involves a wide variety of fabrics, from lightweight chiffon to heavy tweed, requiring frequent fabric changes during production. Lacking an adaptive height adjustment component, this alignment device causes problems when handling thick fabrics; the fabric doesn't move smoothly within the aligner, easily resulting in wrinkles. Conversely, when handling thin fabrics, it cannot fully conform to the aligner, leading to frequent sewing misalignment issues and severely impacting garment production quality.
[0004] Meanwhile, the limitations of existing positioning devices, with their singular functionality, are particularly pronounced in the sewing process. In garment sewing, a single product often contains both straight seams (such as waistbands and shirt plackets) and curved seams (such as cheongsam collars and dress armholes). However, traditional devices are limited in function, either only supporting straight track positioning or relying on fixed curved molds, making it impossible to quickly switch between straight and curved positioning functions on the same device, thus failing to meet the production needs of complex garment styles.
[0005] To address this issue, a fabric alignment device for garment production is provided. Utility Model Content
[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a fabric alignment device for garment production, which solves the problems of existing alignment devices, such as fixed limiting height, inability to adapt to fabrics of different thicknesses leading to sewing quality issues, and single function that cannot achieve rapid switching between straight and curved positioning.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A fabric alignment device for garment production includes a base. A mounting groove is formed on the lower surface of the base, and a magnet is fixedly installed within the mounting groove. A threaded post is fixedly installed on the upper surface of the base. A pressure plate is fitted onto the outer surface of the threaded post. A vertical plate and an arc-shaped plate are fixedly installed on the left and right sides of the lower surface of the pressure plate, respectively. The vertical plate and the pressure plate form an L-shaped structure for straight-line positioning guidance during fabric sewing. The arc-shaped plate, in conjunction with the pressure plate, is used for positioning guidance along the arc direction of the fabric during sewing. A spring is installed between the pressure plate and the base. An adjustment component is screwed onto the outer surface of the threaded post. The adjustment component, in conjunction with the spring, adjusts the pressure of the pressure plate to change its limiting height, adapting to fabrics of different thicknesses.
[0009] In the above technical solution, the adjustment component includes a threaded cylinder that is threadedly connected to the threaded column. The lower surface of the threaded cylinder presses against the upper surface of the pressure plate, and a screw head for driving the threaded cylinder to rotate and adjust is fixedly installed at the top of the threaded cylinder.
[0010] In the above technical solution, slots are symmetrically opened on the left and right sides of the upper surface of the base, and directional rods that form a plug-in mating structure with the slots are fixedly installed on the lower surfaces of the vertical plate and the arc plate. The directional rods slide vertically within the slots to guide the pressure plate so that it can only move and adjust in the vertical direction.
[0011] In the above technical solution, the right surface of the base is an arc-shaped surface, the diameter of the arc-shaped surface of the base is the same as the inner diameter of the arc plate, and the arc-shaped surface of the base and the right arc-shaped surface of the arc plate are on the same longitudinal horizontal line; the left surface of the base is a plane, and the plane of the base and the left surface of the vertical plate are on the same longitudinal horizontal line.
[0012] In the above technical solution, the threaded column and the base are fixedly connected by welding.
[0013] The fabric alignment device for garment production of this utility model has the following advantages compared with the prior art:
[0014] This invention utilizes an adjustable component and a spring to construct an adaptive height adjustment mechanism, enabling flexible adjustment of the limiting thickness for fabrics of varying thicknesses, from chiffon to tweed. This avoids wrinkles in thick fabrics and misalignment in thin fabrics, improving fabric adaptability. Furthermore, the vertical and curved plates on the lower surface of the pressure plate form a dual-function positioning structure, adapting to both straight and curved seam positioning. This allows for quick switching without changing molds, meeting the sewing needs of complex shapes such as cheongsam necklines and improving production efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-3 This utility model provides a technical solution:
[0021] A fabric alignment device for garment production includes a base 1. The lower surface of the base 1 is provided with an installation groove, and a magnet 11 is fixedly installed in the installation groove by strong adhesive. The magnet 11 can magnetically fix the base 1 to the table of a sewing machine. A threaded post 2 is fixedly installed on the upper surface of the base 1. A pressure plate 3 is sleeved on the outer surface of the threaded post 2. A vertical plate 31 and an arc plate 32 are welded and fixedly installed on the left and right sides of the lower surface of the pressure plate 3, respectively. The vertical plate 31 and the pressure plate 3 are assembled to form an L-shape for straight positioning and guidance during fabric sewing. The arc plate 32 works with the pressure plate 3 to position and guide the arc direction of the fabric during sewing. Both can reduce the difficulty of sewing operations and improve sewing quality and efficiency through positioning and guidance.
[0022] A spring 4 is fixedly installed on the upper surface of the base 1. The top of the spring 4 presses against the lower surface of the pressure plate 3. An adjustment component 5 for limiting the pressure plate 3 is screwed onto the outer surface of the threaded post 2. The degree of pressing on the pressure plate 3 can be adjusted by the cooperation of the adjustment component 5 and the spring 4, thereby changing the limiting height of the pressure plate 3. This makes the alignment device applicable to fabrics of different thicknesses and enhances its applicability.
[0023] It should be noted that, as Figure 2As shown, the adjusting assembly 5 includes a threaded cylinder 51, which is threadedly connected to the threaded post 2. The lower surface of the threaded cylinder 51 presses against the upper surface of the pressure plate 3 to achieve compression and limiting of the pressure plate 3. A screwing head 52 is fixedly installed at the top of the threaded cylinder 51 by welding. This screwing head 52 constitutes a force-saving screwing structure, which can drive the threaded cylinder 51 to rotate and adjust. When the threaded cylinder 51 is screwed upward by the screwing head 52, the spring 4, with its own elastic restoring action, pushes the pressure plate 3 upward, thereby increasing the limiting thickness of the fabric, making the device suitable for positioning thicker fabrics. Conversely, when the threaded cylinder 51 is screwed downward, the spring 4 is compressed, and the pressure plate 3 moves downward, thereby reducing the limiting thickness to be suitable for positioning thinner fabrics. This achieves adaptive adjustment for positioning fabrics of different thicknesses, effectively improving the applicability of the device.
[0024] In addition, combined Figure 2 and Figure 3 As shown, to ensure the guiding accuracy of the vertical plate 31 and the arc plate 32 during the up-and-down movement adjustment of the pressure plate 3 and to avoid lateral displacement, slots 12 are symmetrically opened on the left and right sides of the upper surface of the base 1. At the same time, a guide rod 33 is fixedly installed on the lower surface of the vertical plate 31 and the arc plate 32 by welding. The guide rod 33 and the slot 12 form a plug-in mating structure. Through the vertical sliding guide of the guide rod 33 in the slot 12, the pressure plate 3 can only move and adjust in the vertical direction, thereby effectively ensuring the guiding accuracy of the vertical plate 31 and the arc plate 32 and ensuring the stability and reliability of the positioning mechanism.
[0025] Finally, considering that when the vertical plate 31 and the arc plate 32 are used for positioning thicker fabrics, there is a certain gap between the two and the sewing machine table. When sewing the fabric, the uneven friction between the upper and lower sections of the fabric can easily cause deviation, affecting the guiding accuracy and sewing quality.
[0026] To further improve guiding accuracy, the right surface of base 1 needs to be set as an arc shape, with the diameter of the arc surface being the same as the inner diameter of the arc plate 32. The arc surface of base 1 and the right arc surface of arc plate 32 are on the same longitudinal horizontal line. The left surface of base 1 is a plane, which is on the same longitudinal horizontal line as the left surface of vertical plate 31. In actual use, the plane and arc surface of base 1 can be used to guide the lower end of the fabric in the same direction, effectively offsetting the tension fluctuations caused by the sewing machine needle piercing or the movement of the fabric feeding mechanism during sewing, preventing the fabric from being misaligned due to uneven force, and ensuring that the fabric is in a "positioning-limiting" state in both the upper and lower sections. This ensures the consistency between the sewing trajectory and the preset path, significantly improving the accuracy and reliability of sewing processing.
[0027] Working Principle: In actual use, firstly, the base 1 is magnetically fixed to the target position on the sewing machine table. The magnetic attraction of the magnet 11 enables quick positioning and flexible disassembly. Simultaneously, the orientation of the vertical plate 31 or the curved plate 32 can be adjusted according to the sewing process requirements to align it with the fabric guide path. After positioning, the clamping force of the pressure plate 3 is adjusted according to the thickness of the fabric to be processed by operating the adjustment component 5: Turning the screw head 52 clockwise moves the threaded cylinder 51 downwards along the threaded post 2, compressing the spring 4 and pushing the pressure plate 3 downwards, reducing the downward pressure distance between the vertical plate 31 and the curved plate 32 on the fabric, suitable for thinner fabrics; turning the screw head 52 counterclockwise moves the threaded cylinder 51 upwards, and the spring 4 elastically returns to its original position, pushing the pressure plate 3 upwards, increasing the downward pressure distance, suitable for thicker fabrics, until the lower surface of the pressure plate 3 is tightly fitted to the fabric without excessive compression or deformation.
[0028] At this time, under the vertical guidance and constraint of the directional rod 33 and the slot 12, the pressure plate 3 can only move in the vertical direction, ensuring the positioning accuracy of the vertical plate 31 and the arc plate 32. During the sewing process, when the fabric travels along the surface of the vertical plate 31 or the arc plate 32, the pressure plate 3, through the upper and lower friction couples and the geometric limiting structure, works together to counteract the sewing tension fluctuations and constrain the fabric displacement, thereby achieving high-precision guidance and improving the regularity of the sewing stitches and the processing effect.
