Abstract
Description
Technical Field
[0001] The utility model relates to a flat sewing machine for sewing webbing. Background Art
[0002] In the process of sewing the webbing on the flat-bed sewing machine, due to the different elasticity of the webbing and the different matching degree with the fabric, it is necessary to ensure that the webbing is tension-free and sewn synchronously with the fabric during the production process to ensure the flatness of the webbing and the finished garment. The conventional sewing method requires the webbing to be pre-shrinked first, and then the fabric is manually stretched or pushed during the sewing process to adapt to the elasticity of the webbing. This method has different manual operation strengths, and the flatness of the finished product is also different. At the same time, the accuracy of the position must also be taken into account. The product quality consistency is poor, which can easily cause the finished product to be wrinkled and uneven, and the position is inaccurate, affecting the appearance and wearing experience. By modifying the sewing machine work surface and adding a synchronous transmission wheel and an adjustable positioning device, the problems of wrinkling and inaccurate position of the finished product after sewing the webbing can be solved.

[0015] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.
[0016] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0017] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.
[0018] Example 1
[0019] like Figure 1 As shown, a flat sewing machine 1 is arranged on the work surface; a webbing conveying device is arranged above the head of the flat sewing machine on the work surface; the conveying device comprises: a bracket 1 is arranged on the work surface, the bracket is made of metal and is fixed to the work surface by bolts. A fixing plate 7 is vertically arranged on the upper end of the bracket, and a support arm 2 is arranged on the fixing plate;
[0020] A driving wheel 4 connected to a driving device 8 is provided on one side of the fixing plate; the driving device 8 is generally a reduction motor, which can be directly arranged on the rear side of the fixing plate, and its driving shaft passes through the fixing plate and extends to the front side of the fixing plate; the driving wheel is installed on the driving shaft; a first webbing positioning member 5 and a second webbing positioning member 6 are provided on the fixing plates on both sides of the driving wheel; the webbing positioning member is adjustable, such as Figure 3 As shown, a fixed baffle 62 is usually provided on the shaft 61, and an adjustable baffle 63 is provided on the other side of the shaft 61; wherein the adjustable baffle is made of a damping material, such as rubber, etc., and can be pushed on the shaft 61 under a large external force.
