Description

Technical Field

[0001] This utility model relates to the field of down sewing template technology, and more specifically, it relates to a down jacket pocket flap sewing template. Background Technology

[0002] Pocket trim for down jackets is a common strip-shaped material used to fix the shape of down jacket pockets inside. It is an essential item for down jacket pockets. With the development of technology, the demand for down jackets is constantly increasing. In order to meet people's needs and speed up the manufacturing process of down jackets, many auxiliary devices have been invented, including down jacket pocket trim sewing templates. With the rapid development of technology, people's requirements for down jacket pocket trim sewing templates are getting higher and higher. However, existing down jacket pocket trim sewing templates have certain defects that affect daily use.

[0003] The primary problem is that traditional down jacket pocket trim sewing templates lack width adjustment devices. Down jacket trim widths vary with design requirements, and without an adjustable device, each width requires a custom-made template, increasing equipment investment costs. When changing to different trim widths, the old template must be completely disassembled, a new template installed, and the baseline recalibrated, a process that takes too long and extends downtime. Down jackets often use coated waterproof fabrics or reinforced trims. If the width cannot be adjusted and a thick trim is inserted into a narrow positioning groove, the edges will turn outward due to compression, preventing the stitching from following the trim's base and increasing the risk of down leakage.

[0004] More notably, the seam allowance of traditional down jacket pocket trim sewing templates is non-removable. The elasticity of the seam allowance decreases with repeated use. The non-removable design means that pressure cannot be restored by replacing the seam allowance, and the positioning accuracy of the trim must be accepted as it continues to decline. To compensate for insufficient pressure, operators may over-press the template, causing the fabric to stretch and deform, resulting in a shortening deviation in the length direction of the trim. The diversity of down jacket fabrics also requires different seam allowance materials. Some materials need to be non-slip, while others need to be anti-snagging. The same template cannot be adapted to the production of multiple fabrics, forcing companies to customize templates for special fabrics, increasing investment costs.

[0005] Crucially, traditional down jacket pocket trim sewing templates lack anti-static devices. Down jacket trim sewing involves multiple layers of fabric, including the body fabric and trim fabric. Static electricity generates attraction, causing the trim fabric to stick tightly to the template or body, making it difficult to lay flat. This leads to misalignment between the edges and the positioning grooves, especially for narrow trims, which are more prone to skew due to attraction. This results in uneven stitch widths, and the slippery coated fabric is randomly attracted, requiring operators to repeatedly peel and adjust it by hand, increasing positioning time per unit. Furthermore, the down jacket production environment contains a large amount of down debris and short fabric fibers. Static electricity can turn the template into a collector of impurities, attracting surrounding materials and dust onto the garment, causing stains and defects. Utility Model Content

[0014] The present invention is further provided that the pressure strip body is provided with anti-slip texture, which improves the stability of the down jacket when placed.

[0015] The present invention is further configured such that the locking member and the locking block are connected by threads.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a template for sewing pocket flaps in down jackets, which has the following advantages:

[0018] 1. Through the tight cooperation between the pressure plate, connecting column, slider, bayonet and limit block, a complete width adjustment device is formed. The width adjustment device can replace multiple sets of fixed width templates, solving the problem of one template per style, saving storage space. When dealing with urgent orders or style changes, there is no need to wait for new template customization, and production can be started directly, improving order response speed. When sewing thick strips, adjusting the width can make the thick strips flat, improving sewing accuracy.

[0019] 2. Through the tight cooperation between the groove, insert, pressure strip, locking block, and locking parts, a complete set of detachable pressure strips is formed. Considering the special characteristics of down jacket fabrics, the detachable pressure strips can achieve targeted protection by replacing them with pressure strips of different materials and hardness. For thick gussets filled with down, replacing them with elastic pressure strips with a cushioning layer can both compress the fabric and prevent the filling layer from collapsing, maintaining the fluffiness of the gusset. For waterproof coated fabrics, replacing them with anti-slip pressure strips with slightly raised textures can effectively reduce the risk of slippage. The detachable design solves the problem of difficult-to-clean dirt accumulation in the gaps of the fixed pressure strips. After the pressure strips are removed, the gaps where the positioning groove and the pressure strips contact can be cleaned directly, removing accumulated down debris and fabric fibers to prevent impurities from being sewn into the fabric, which would reduce the down leakage rate during later wear. The pressure strip is the fastest-wearing part of the template; the detachable design allows for partial replacement. When scratches appear on the surface of the pressure strip or the anti-static coating peels off, only the individual pressure strip needs to be replaced, without scrapping the entire template, reducing maintenance costs.

[0020] 3. A complete anti-static device is formed by the close cooperation of the brush, copper foil, grounding terminal, tongue, and grounding wire. The anti-static device can quickly neutralize the static electricity on the fabric surface, eliminate the adsorption between the fabric and the template, and between fabrics, so that the positioning of the trim strip is no longer affected by static electricity and deviates. After the static electricity is eliminated, the pressure distribution between the trim strip and the fabric is more uniform, making the fabric and the trim strip surface fit more closely and the sewing more accurate. The trim strip fabric containing down will not pill due to static electricity. After the static electricity on the template surface is eliminated, the adsorption capacity of oil and dust is greatly reduced, reducing the occurrence of fabric stains. The static voltage is controlled within a safe range to avoid physical damage to the down jacket fabric and also reduce the direct damage to workers caused by static electricity.

The grounding wire 13 is fixedly connected to the grounding terminal 11.

[0031] In a further embodiment of this application, the detachable pressure strip includes a groove 14, an insert 15, a pressure strip body 16, a locking block 17, and a locking member 18. The groove 14 is fixedly connected to the first template 1 and slidably connected to the insert 15. The pressure strip body 16 is fixedly connected to the insert 15 and movably connected to the second template 2. The locking block 17 is slidably connected to the groove 14 and movably connected to the insert 15. The locking member 18 is movably connected to the insert 15 and the groove 14 respectively.

[0032] In a further embodiment of this application, the first template 1 is provided with a handle 19, which is used to push the first template 1 and the second template 2 to move, thus facilitating the sewing of the down jacket.

[0033] In a further embodiment of this application, both the second template 2 and the pressure plate 4 are provided with two magnetic strips 20, so that the down jacket and the vent strip can be clamped and fixed.

[0034] In a further embodiment of this application, the second template 2 is provided with an expansion connection mechanism, which includes a support rod 21 and an expansion column 22. The support rod 21 is fixedly connected to the second template 2 and the expansion column 22 respectively. The expansion column 22 connected to the support rod 21 enables future expansion components to be fixed or rotated with the second template 2.

[0035] In a further embodiment of this application, the pressure strip 16 is provided with anti-slip texture to prevent the down jacket from sliding and causing sewing deviation.

[0036] In a further embodiment of this application, the locking member 18 and the locking block 17 are connected by threads. The locking member 18 rotates within the locking block 17 and contacts the groove 14 to fix the position of the locking block 17.

[0037] In this embodiment, when the device is needed, the down jacket is placed on the second template 2, and the area where the seam strip needs to be sewn is placed in the sewing hole 3. The first template 1 covers the down jacket. The size of the pressure plate 4 covering the sewing hole 3 is adjusted by moving the slider 6 on the connecting column 5. Then, the limiting block 8 is used to lock the connecting column 5 and is set inside the slot 7 and outside the pressure plate 4 to limit the movement of the pressure plate 4. The seam strip is then placed between the pressure plate 4 and the first template 1, and the first template 2 is pressed down so that the magnetic strips 20 attract each other. The seam strip is fixed and the handle 19 is pushed so that the first template 1 and the second template 2 sew through the needle. When the first template 1 and the second template 2 cover the down jacket, static electricity is easily generated. When the down jacket is placed, it will come into contact with the brush 9.

When the first template 1 and the second template 2 cover the down jacket, static electricity is easily generated. When the down jacket is placed, it will come into contact with the brush 9. The brush 9 will collect the static electricity through the copper foil 10 and transfer it to the grounding terminal 11 through the tongue 12. The grounding terminal 11 then transfers the static electricity to the grounding grid of the workshop through the grounding wire 13 to remove the static electricity.

[0040] More specifically, when it is necessary to replace or clean the pressure strip body 16, the locking member 18 is unscrewed so that the locking block 17 can be slid out along the groove 14, and the pressure strip body 16 and the insert block 15 can be removed from the groove 14 for replacement or cleaning. The extension column 22 connected to the support rod 21 allows future extension parts to be fixed or rotated with the second template 2.
