Description

Technical Field

[0001] The present invention relates to the technical field of sewing equipment, and in particular to an auxiliary tool and a manufacturing method for manufacturing an inward-turned pocket. Background Art

[0002] Garment processing is a method of garment production mainly based on modern machine processing and supplemented by manual processing. The processing of garments mainly includes the following processes: inspection of incoming fabrics and accessories → technical preparation → cutting → sewing → buttonholing and button sewing → pressing → inspection of finished garments → packaging → warehousing or shipping. After the fabrics enter the factory, the quantity, appearance and internal quality need to be inspected, and only those that meet the production requirements can be put into production. The sewing of pockets is a very important part of the garment sewing process, and it is also the part with the highest technical requirements for technicians in the sewing process. At present, the sewing of pockets is all completed manually. Especially for inward-turned pockets, workers need to manually turn the edges and align them, and then press them on the clothing for sewing. Often, the pocket edges are misaligned, resulting in unqualified pocket quality, and the pocket position deviates due to inaccurate sewing positions. Therefore, it is necessary to design an auxiliary tool and a manufacturing method for manufacturing an inward-turned pocket to quickly turn the pocket fabric edges to improve the sewing efficiency, and clamp the turned edges to ensure that the edges will not spread during the sewing process, thus ensuring the quality of the pocket stitches. Summary of the Invention

[0003] In order to overcome the above deficiencies in the prior art, the present invention provides an auxiliary tool for manufacturing an inward-turned pocket, which can quickly turn the pocket fabric edges to improve the sewing efficiency, and clamp the turned edges to ensure that the edges will not spread during the sewing process, thus ensuring the quality of the pocket stitches.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] An auxiliary tool for manufacturing an inward-turned pocket includes an outer fixing plate, an inner support plate, a folding edge plate and a sewing line guiding plate. A placement groove for placing the pocket to be sewn is provided on the outer fixing plate. The inner support plate is arranged in the placement groove and is adapted to the placement groove. An opening for facilitating the removal of the inner support plate is provided at one end of the placement groove. The folding edge plate is slidably connected to the outer fixing plate, and one end of the folding edge plate extends into the placement groove. The sewing line guiding plate covers the placement groove. One end of the sewing line guiding plate is hinged to the outer fixing plate. A U-shaped guiding groove is provided on the sewing line guiding plate. The middle part of the pocket to be sewn is arranged between the inner support plate and the sewing line guiding plate, and three sides of the pocket to be sewn are turned over the inner support plate and arranged between the inner support plate and the folding edge plate.

[0006] In the above technical solution, during the process of sewing the pocket, the auxiliary tool quickly turns over the pocket fabric and clamps the turned edge to ensure that the turned edge does not come loose during the sewing process, ensuring the quality of the pocket stitches. And due to the special auxiliary tool, the pocket size and position can be guaranteed, further improving the quality of the inner-turned-edge pocket. The usage method of the auxiliary tool is as follows: First step: Place the outer fixing plate flat, with the side where the inner support plate is set facing upwards. Align the pocket fabric and place it on the placement groove. The outer edge of the pocket fabric extends beyond the range of the placement groove and covers the outer fixing plate. Then place the inner support plate into the placement groove to press the pocket fabric. Second step: Push the folding plate out from the outer fixing plate into the placement groove so that the outer edge of the pocket fabric covering the outer fixing plate is turned inwards to form a turned edge, and the folding plate and the inner support plate press the turned edge. Third step: Turn the entire outer fixing plate over, align it with the position on the clothing where the pocket needs to be sewn, then press the stitch guiding plate, slowly pull out the inner support plate, and retract the folding plate. Fourth step: Align the sewing machine needle with the U-shaped guiding groove for sewing. After sewing is completed, remove the auxiliary tool. By using the auxiliary tool, the pocket quality can be improved and the pocket sewing efficiency can be increased.

[0007] Preferably, the number of the folding plates is two. The two folding plates are respectively arranged on both sides of the placement groove, and the sliding direction of the folding plates is inclined relative to the opening direction of the pocket. This structure can make the folding plates slide inwards from both sides respectively to fold the turned edge of the pocket to be sewn inwards. And because the sliding direction of the folding plates is inclined, the two folding plates can fold three turned edges.

[0008] Preferably, a first pulling soft strip for conveniently pulling the folding plate is provided on the folding plate; a second pulling soft strip for conveniently pulling the inner support plate is provided on the inner support plate. The first pulling soft strip and the second pulling soft strip facilitate pulling out the folding plate and the inner support plate.

[0009] Preferably, the number of the stitch guiding plates is two. The two stitch guiding plates are overlapped, and the U-shaped guiding grooves on the two stitch guiding plates are offset inside and outside. The hinge positions of the two stitch guiding plates and the outer fixing plate are respectively located on the opposite sides of the placement groove. This structure can guide two different stitches by switching the two stitch guiding plates to form a double-stitch effect.

[0010] Preferably, the outer fixing plate, the inner support plate, the folding plate and the stitch guiding plate are made of transparent materials. This transparent structure facilitates observing the folding situation of the pocket.

[0011] Preferably, a first auxiliary alignment line is provided on the inner support plate, and a second auxiliary alignment line is provided on the stitch guiding plate. This structure facilitates aligning the position when the inner support plate is placed.

[0012] Preferably, an anti-error plate is fixed on the hemming plate, and the sewing thread guiding plate is arranged between the anti-error plate and the hemming plate; when the hemming plate extends into the placing groove, the anti-error plate blocks the position of the U-shaped guiding groove on the sewing thread guiding plate; when the hemming plate retracts, the anti-error plate is staggered from the U-shaped guiding groove. A reminder mark is provided on the anti-error plate, which blocks the U-shaped guiding groove. If the hemming plate does not retract during sewing, it will cause damage to the hemming plate and the sewing needle. To reduce misoperation, the anti-error plate is used to block the position of the U-shaped guiding groove. If the worker does not retract the hemming plate, the anti-error plate will block the position of the U-shaped guiding groove, and the worker cannot perform guiding sewing, which can remind the worker to retract the hemming plate.

[0013] Preferably, a snap for clamping the clothing is provided on the outer fixing plate. The snap facilitates fixing foreign objects and prevents the pocket to be sewn and the clothing from being misaligned during sewing.

[0014] A method for manufacturing an in-turned pocket uses the above-mentioned auxiliary tool for manufacturing an in-turned pocket, and includes the following steps:

[0015] a. Pocket fabric placement: Lay the outer fixing plate flat, with the side provided with the inner support plate facing up. Align the pocket fabric and place it on the placing groove. The outer edge of the pocket fabric exceeds the range of the placing groove and covers the outer fixing plate. Then place the inner support plate into the placing groove to press the pocket fabric.

[0016] b. Pocket hemming: Push the hemming plate out from the outer fixing plate into the placing groove so that the outer edge of the pocket fabric covering the outer fixing plate is turned in to form a hem, and the hemming plate and the inner support plate press the hem tightly.

[0017] c. Flip alignment: Flip the entire outer fixing plate over and align it with the position on the clothing where the pocket needs to be sewn. Then press the sewing thread guiding plate tightly, slowly pull out the inner support plate, and retract the hemming plate.

[0018] d. Pocket sewing: Align the sewing machine needle with the U-shaped guiding groove for sewing. After sewing is completed, remove the auxiliary tool.

[0019] Preferably, in step d., when the number of hemming plates is two, first open the first hemming plate, use the U-shaped guiding groove on the second hemming plate for sewing, then open the second hemming plate, cover the first hemming plate, and use the U-shaped guiding groove on the first hemming plate for sewing, so that double sewing lines can be sewn.

[0020] The beneficial effects of the present invention are: (1) During the pocket sewing process, the auxiliary tool quickly turns the edge of the pocket fabric to improve the sewing efficiency, and clamps the hem to ensure that the hem will not spread during sewing, ensuring the quality of the pocket sewing thread; (2) Using the anti-error plate to block the position of the U-shaped guiding groove can remind the worker to retract the hemming plate and reduce misoperation.
