[0001] The utility model relates to down jacket production field especially, relates to a kind of inner bag outer cover positioning nested sewing device for down jacket production. BACKGROUND

[0002] In the production and processing of down jacket, the nesting sewing of inner bag and outer cover is a key process, and its sewing accuracy directly affects the finished product quality and thermal performance of down jacket.

[0003] Traditional sewing operation is mostly dependent on manual positioning.

[0004] However, due to the fluffy nature of the down jacket inner bag, the inner bag is prone to displacement during sewing, and the outer cover fabric is prone to wrinkles, which not only causes the sewing stitches to be skewed and misaligned, affecting the appearance and durability of the product, but also significantly reduces the sewing efficiency. At the same time, manual pressing positioning is difficult to ensure uniform pressure, which can easily cause the down to be pressed and clumped, damaging the loftiness of the down jacket. In addition, the existing positioning device needs to be frequently released during adjustment of the sewing position, which is tedious to operate and further restricts the production progress. Therefore, a down jacket production inner bag outer cover positioning nested sewing device is proposed to solve the above problems. SUMMARY

[0005] To make up for the above shortcomings, the utility model provides an inner bag outer cover positioning nested sewing device for down jacket production, which aims to improve the problem of the fluffy nature of the down jacket inner bag, which is prone to displacement during sewing.

[0018] 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.

[0019] Reference Figure 1 , Figure 2 , Figure 5 This utility model provides an embodiment of a positioning and nesting sewing device for the inner lining and outer cover of a down jacket. It includes a workbench 1 with a positioning mechanism. The positioning mechanism includes a pressure strip 5 positioned above the workbench 1. The pressure strip 5 has a through groove 51. Smoothing rollers 53 are respectively positioned on both sides below the pressure strip 5. Connecting rods 52 are rotatably connected to both ends of the two smoothing rollers 53. The end of the connecting rod 52 away from the smoothing roller 53 is rotatably connected to the opposite side of the pressure strip 5. The connecting rods 52 on the pressure strip 5 are all bent towards the side away from the pressure strip 5. This allows for the positioning of the inner lining when needed. When sewing the outer cover, the part to be sewn is moved under the pressure strip 5 and positioned by pressing down the pressure strip 5. When the pressure strip 5 is pressed down, the smoothing rollers 53 on both sides will first contact the outer cover of the inner liner. As the pressure strip 5 continues to press down, since the connecting rod 52 of the smoothing roller 53 is slightly bent outward from the pressure strip 5, the smoothing rollers 53 on both sides will move away from the pressure strip 5 and roll during the pressing down process. In this process, the outer cover of the inner liner will be opened and smoothed to facilitate the subsequent sewing needle to pass through the through groove 51 on the pressure strip 5 for sewing, and to avoid the fluffy inner liner causing wrinkles in the outer cover during sewing, which would affect the sewing quality.

[0020] Reference Figure 2 , Figure 3 , Figure 4The positioning mechanism also includes a cylinder 21, which is fixedly connected to the bottom of the workbench 1. A connecting frame 2 is fixedly connected to the bottom of the cylinder 21. Two sets of support frames 3 are provided on the top of the workbench 1. Support frames 3 are fixedly connected to both sides of the top of the connecting frame 2, and the two sets of support frames 3 are located above the workbench 1. Pressure plates 4 are fixedly connected to both sides of the pressure strip 5, which are used to press down the outer cover of the inner liner when the smoothing roller 53 rolls. The pressure plate 4 is fixedly connected to the support frame 3 on the corresponding side. The extension and retraction of the cylinder 21 can easily drive the support frame 3 connected to the connecting frame 2 to move up and down. The movement of the support frame 3 will drive the pressure plate 4 and the pressure strip 5 to move together.

[0021] Reference Figure 2 , Figure 4 The inner wall of the support frame 3 is slidably connected to a slide frame 31, and the inner wall of the slide frame 31 is rotatably connected to a pressure roller 32. The two sides of the support frame 3 are respectively provided with slide grooves 311, and the two sides of the slide frame 31 are respectively fixedly connected to sliders 312, and the sliders 312 slide in the corresponding slide grooves 311. A spring 33 is fixedly connected between the support frame 3 and the top of the slide frame 31. When the support frame 3 moves down, it will drive the pressure roller 32 inside the slide frame 31 to press down on the outer cover of the inner liner. Due to the tension of the spring 33, the slide frame 31 will be pushed down, so that the pressure roller 32 presses down on the outer cover of the inner liner with appropriate pressure, so as to prevent the fluffy inner liner from excessively lifting the outer cover and affecting the sewing. The surface of the pressure roller 32 is evenly distributed with balls 321. By setting the balls 321, when changing the sewing position, it is only necessary to lift the smoothing roller 53 away from the outer cover of the inner liner. When the pressure roller 32 is pressing down on the outer cover of the inner liner, the outer cover of the inner liner can be freely dragged to adjust the sewing position.

[0022] Working principle: When performing nested sewing of the inner lining and outer cover of a down jacket, first place the inner lining and outer cover to be sewn on the workbench 1, and move the part to be sewn to be directly below the pressure strip 5; then start the cylinder 21, the cylinder 21 retracts and drives the connecting frame 2 to move down, which in turn drives the two sets of support frames 3 to move down synchronously. During the downward movement of the support frame 3, the pressure roller 32 on its internal sliding frame 31 will first contact and press the inner lining and outer cover. At this time, the spring 33 will adaptively extend and retract according to the fluffiness of the outer cover, providing uniform pressure to the pressure roller 32 to achieve initial positioning.

[0023] As the support frame 3 continues to move downward, the smoothing rollers 53 on both sides of the pressure strip 5 will first contact the inner liner and outer cover. Since the connecting rod 52 is bent outward, when the pressure strip 5 continues to press down, the connecting rod 52 will drive the smoothing rollers 53 to roll away from the pressure strip 5, thereby smoothing the outer cover fabric to both sides. After the pressure strip 5 is fully pressed down, the pressure plate 4 will press the smoothed outer cover edge again. At this time, the sewing needle can pass through the through groove 51 on the pressure strip 5 to complete the precise sewing.

[0024] When the sewing position needs to be adjusted, simply control the cylinder 21 to retract slightly, so that the pressure strip 5 and the smoothing roller 53 are lifted away from the inner liner and outer cover. Under the action of the ball 321, the pressure roller 32 can maintain the basic limit on the inner liner and outer cover while dragging the outer cover with the worker to adjust the position. After the adjustment is completed, control the cylinder 21 to retract again to continue the sewing operation and complete the entire positioning sewing process.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
