Description

Technical Field

[0001] The invention belongs to the technical field of clothing sewing, in particular to a sewing auxiliary tool and a sewing method. Background Art

[0002] When fabrics or cloth are processed into specific garments such as shirts and pants, they are usually sewn together to form a specific shape. This is especially true at the pocket opening, where the edges of the material are folded over to conceal them before sewing to ensure a comfortable hand movement.

[0003] Since fabrics, cloths and other materials are usually thin and soft, the existing technology uses manual folding to fold the edges and then pushes the folded materials into the sewing machine for sewing, resulting in low production efficiency and low product quality. The essential reason is that the manual folding method requires a certain level of proficiency from the operator, which is easily affected by subjective factors, and the folded edges are affected by the craftsmanship and will cause uneven width. Summary of the Invention

[0004] The main purpose of the present invention is to provide a sewing auxiliary tool and a sewing method to solve the problems existing in the prior art and improve the efficiency and quality of hemming and sewing.

[0005] In order to achieve the above object, one of the solutions of the present invention is: A sewing auxiliary tooling comprises a base, a pressure strip, a movable pressure plate and a limit plate; one end of the pressure strip is mounted on the upper surface of the base for pressing the material on the upper surface of the base; the movable pressure plate and the limit plate are respectively mounted on the upper surface of the base on both sides of the pressure strip; the movable pressure plate is horizontally movable to fit above the pressure strip for pressing the edge of the material on the upper surface of the pressure strip; the opposing surfaces of the movable pressure plate and the limit plate are respectively provided with a pressure plate side surface and a limit side surface parallel to each other; when the movable pressure plate moves horizontally, the pressure plate side surface moves from the side of the pressure strip away from the limit plate to push the material against the limit side surface.

[0006] One end of the pressure strip is fixed to the upper surface of the base by screws.

DETAILED DESCRIPTION

[0025] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0026] refer to Figure 1-5 As shown, the present invention discloses a sewing auxiliary tool, comprising a base 1, a pressure strip 2, a movable pressure plate 3 and a limit plate 4; One end of the pressure strip 2 is mounted on the upper surface of the base 1 and is used to press the material a onto the upper surface of the base 1 (see Figure 6 Status); The movable pressing plate 3 and the limiting plate 4 are respectively installed on the upper surface of the base 1 on both sides of the pressure strip 2; the movable pressing plate 3 is horizontally movable and fits above the pressure strip 2 to press the edge of the material a on the upper surface of the pressure strip 2 (see Figure 7 Status); The opposite surfaces of the movable pressing plate 3 and the limiting plate 4 are respectively provided with a pressing plate side surface 31 and a limiting side surface 41 which are parallel to each other; when the movable pressing plate 3 moves horizontally, the pressing plate side surface 31 moves from the side of the pressure bar 2 away from the limiting plate 4 to push the material a against the limiting side surface 41 (see Figure 7 、 8 status).

[0027] Through the above scheme, the present invention can be used to assist in fixing the edge of the material a to achieve hemming and sewing operations, which is beneficial to improving the efficiency of sewing and thus improving the production efficiency and quality of the product. Figure 6 As shown, the pressure strip 2 can first press the material a against the upper surface of the base 1, and make the edge of the material a to be sewn fit on the upper surface of the movable pressing plate 3; then, refer to Figure 7 As shown, the movable pressing plate 3 is manually pushed toward the pressure strip 2 until the pressure plate side 31 pushes the material a against the limiting side 41. During the process of being pushed out, the movable pressing plate 3 will naturally fold the edge of the material a and press it against the upper surface of the pressure strip 2, thereby realizing the folding operation; then, refer to Figure 8 As shown, the unpressed part of the material a is manually folded over to the upper surface of the movable pressing plate 3, and then the material a can be placed at a preset position (see Figure 8 、 9 The material a is sewn at the point where the edge of the material a is folded (the broken line in the middle is located on the inner side of the folded edge of the material a). During the sewing process, the material a is continuously and slowly pushed toward the needle until the sewing is completed. The material a is firmly fixed by the pressing strip 2 and the movable pressing plate 3 to ensure that the material a does not shift before and after the folding edge and during the sewing process. At the same time, the limit plate 4 limits the maximum stroke of the movable pressing plate 3, thereby controlling the width d of the material a being sewn (see Figure 9 ).

[0028] Specific embodiments of the present invention are shown below.

[0029] refer to Figure 1 As shown, one end of the above-mentioned pressure strip 2 is fixed to the upper surface of the base 1 by a screw 5 to achieve a detachable connection. In actual production, different pressure strips 2 can be replaced according to production needs.

[0030] The limiting plate 4 is provided with at least two first waist holes 42 extending perpendicularly to the side surface 31 of the pressure plate. Each first waist hole 42 engages a screw 6 secured to the upper surface of the base 1. Thus, by loosening the screw 6, the limiting plate 4 can be unlocked, allowing it to be moved horizontally on the upper surface of the base 1 to adjust its position, thereby adjusting the distance between the limiting side surface 41 and the pressure strip 2, and ultimately adjusting the width d of the material a being sewn. This makes the tooling more flexible in practical application and suitable for a wider range of sewing scenarios.

[0031] The upper surface of the base 1 is provided with a mounting seat 7, and the movable pressing plate 3 is movably arranged on the side of the mounting seat 7 facing the pressure strip 2. The mounting seat 7 can be too high a height of the movable pressing plate 3 so that it can move horizontally above the pressure strip 2.

[0032] Furthermore, the mounting base 7 comprises a bottom plate 71, a middle plate 72, and a top plate 73 stacked in sequence. Several screws 8 are sequentially inserted through the top plate 73, the middle plate 72, and the bottom plate 71 to secure the mounting base 7 to the upper surface of the base 1. The middle plate 72 is the same thickness as the movable pressure plate 3 and is provided on either side of the movable pressure plate 3 in its direction of movement. The middle plate 72 and the opposite side surfaces of the movable pressure plate 3 are clearance-matched. Consequently, a through-hole b is formed between the top plate 73, the middle plate 72, and the bottom plate 71, which provides clearance for the movable pressure plate 3 and ensures that the movable pressure plate 3 does not deviate during horizontal movement.

[0033] Secondly, an operating window 731 is defined in the center of the top plate 73; a guide hole 32 is defined in the center of the movable pressure plate 3; and a guide block 10 is fixed to the center of the middle plate 72 via screws 9. The guide block 10 flexibly engages within the guide hole 32. Thus, the provision of the operating window 731 facilitates the user's ability to push the movable pressure plate 3 from above the mounting base 7; the cooperation between the guide hole 32 and the guide block 10 limits the horizontal movement of the movable pressure plate 3 and prevents it from falling out of the mounting base 7.

[0034] Furthermore, the guide block 10 is provided with a second aperture 101 extending perpendicularly to the side surface 31 of the pressure plate. A screw 9, which is locked to the upper surface of the middle plate 72, engages within the second aperture 101. Thus, by loosening the screw 9, the guide block 10 is unlocked, allowing it to move horizontally on the upper surface of the middle plate 72 to adjust its position, thereby adjusting the stroke of the movable pressure plate 3. When combined with the horizontal adjustment of the limit plate 4, the width d of the seam of the material a can be adjusted to the maximum extent.

[0035] The components of the above-mentioned sewing auxiliary tooling are all made of metal materials, which makes the tooling as a whole have a certain hardness and quality. The hardness can ensure the service life, and the quality can ensure that the tooling will not easily shake under force, thereby ensuring stability during use.

[0036] refer to Figure 6-9 As shown, the present invention also discloses a sewing method, which uses the above-mentioned sewing auxiliary tooling, including the following steps: Step 1. Reference Figure 6 As shown, the material a to be sewn is inserted between the pressure strip 2 and the base 1. The pressure strip 2 presses the material a tightly against the upper surface of the base 1, and makes the edge of the material a fit on the upper surface of the movable pressing plate 3. Step 2. Reference Figure 7 As shown, the movable pressing plate 3 is pushed toward the pressure strip 2 until the pressure plate side surface 31 pushes the material a against the limiting side surface 41. During the process of the movable pressing plate 3 being pushed out, the edge of the material a is folded and pressed against the upper surface of the pressure strip 2. Step 3. Reference Figure 8 As shown, the unpressed portion of the material a is folded over to the upper surface of the movable pressing plate 3 at a preset position (see Figure 8 、 9 The point where the thread is broken is located on the inner side of the folded edge of the material a) and the material a is continuously pushed toward the needle during the sewing process until the sewing is completed.

[0037] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
