[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on a fabric, allowing one or more layers of fabric to interweave or sew together. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper.

[0003] Existing sewing machines do not have the function of folding the fabric when sewing together, which means that when sewing the rolled edges of the fabric, manual folding and pressing are still required, which can easily cause danger to the user's hands during the sewing process. In order to improve the above-mentioned problems, a fabric-folding sewing machine is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a fabric-turning sewing machine for sewing fabric. A fabric-turning mechanism is set at the sewing position of the sewing machine body, which allows the fabric to be turned over and positioned when hemming is required. This replaces the manual method of turning and pressing the fabric. At the same time, a positioning mechanism is set on the base to adjust and position the fabric-turning mechanism. This allows the user to easily control the lateral distance between the fabric-turning mechanism and the sewing position of the sewing machine body, and to easily adjust the width of the turned and sewn fabric. This improves the working efficiency of the sewing machine body and solves the problems mentioned in the background art.

[0020] 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.

[0021] This utility model provides, for example Figures 1-4 The illustrated fabric sewing machine includes a base 1 and a sewing machine body 2 mounted on the base 1. A groove 3 is provided on one side of the base 1, and a fabric turning mechanism 4 for sewing is provided in the groove 3. A positioning mechanism 5 is provided on one side of the fabric turning mechanism 4 and is embedded in the base 1. A positioning plate 6 for cooperating with the fabric turning mechanism 4 is placed in the groove 3. The fabric turning mechanism 4 is provided at the sewing position of the sewing machine body 2, which allows the fabric to be turned and positioned when hemming is required, thereby replacing the manual method of turning and pressing the fabric. At the same time, the positioning mechanism 5 is provided on the base 1 to adjust and position the fabric turning mechanism 4, so that the user can easily control the lateral distance between the fabric turning mechanism 4 and the sewing position of the sewing machine body 2, and easily adjust the width of the turned and sewn fabric, thereby improving the sewing efficiency of the sewing machine body 2.

[0022] The material turning mechanism 4 includes a limiting component 41, which is set in a groove 3. A placement plate 42 that works with the limiting component 41 is set in the groove 3. One side of the placement plate 42 is movably connected to a folding plate 43 via a hinge. The other side of the placement plate 42 is rotatably connected to one end of the positioning mechanism 5. By setting the limiting component 41, the position of the placement plate 42 in the groove 3 can be limited, preventing the placement plate 42 from separating from the groove 3. The hinge allows the folding plate 43 to be movably connected to the placement plate 42. When the fabric is placed on the placement plate 42 and the folding plate 43, the fabric can be folded by the movable folding plate 43, which facilitates the sewing work of the sewing machine body 2 on the fabric.

[0023] The positioning mechanism 5 includes a threaded sleeve 51, which is embedded in the base 1. The inner cavity of the threaded sleeve 51 is threadedly connected to a lead screw 52. One end of the lead screw 52 is rotatably connected to one side of the placement plate 42, and the other end of the lead screw 52 is fixedly connected to an adjustment knob 53. By setting the threaded sleeve 51, the lead screw 52 and the adjustment knob 53 together, the user can rotate the lead screw 52 through the adjustment knob 53 to make the lead screw 52 move laterally in the groove 3 to adjust and position the placement plate 42, thereby improving the flexibility of the position adjustment of the placement plate 42.

[0024] The limiting component 41 includes a slide groove 411, which is formed in the groove 3. A positioning rod 412 is fixedly connected to the inner cavity of the slide groove 411. A slider 413 is slidably connected to the positioning rod 412. The top of the slider 413 is fixedly connected to the bottom of the placement plate 42. By setting the cooperation of the slide groove 411, the positioning rod 412 and the slider 413, the placement plate 42 can be limited and slid within the groove 3, preventing the placement plate 42 from moving and separating from the groove 3.

[0025] Both the placement plate 42 and the folding plate 43 have limit grooves 7. The inner cavity of the limit groove 7 is equipped with ball bearings 8 at equal distances. Through the cooperation of the limit groove 7 and the ball bearings 8, the folded fabric can be easily pulled out, which facilitates the sewing process of the fabric.

[0026] The base 1 is provided with a scale line 9, which is located near the groove 3. The scale line 9 facilitates the measurement of the fabric size.

[0027] A spring 10 is sleeved on the positioning rod 412. One end of the spring 10 is fixed in the groove 3, and the other end of the spring 10 is fixed on the slider 413. The spring 10 can provide elasticity to the moving slider 413, so that the spring 10 can provide elasticity to the placement plate 42.

[0028] In practical use, when the fabric needs to be turned over and sewn, the fabric is first laid flat on the placement plate 42 and the folding plate 43. Then, the hinge allows the folding plate 43 to be movably connected to the placement plate 42, so that the fabric can be folded over by the movable folding plate 43, which facilitates the sewing work of the sewing machine body 2. At the same time, through the adjustment of the positioning mechanism 5, and through the cooperation of the threaded sleeve 51, the lead screw 52 and the adjusting knob 53, the user can rotate the lead screw 52 by adjusting the knob 53, so that the lead screw 52 can move... The position of the movable placement plate 42 in the groove 3 is adjusted laterally, which improves the flexibility of the position adjustment of the placement plate 42. It can be convenient to sew the required width of the folded fabric. With the cooperation of the set limiting groove 7 and the ball bearing 8, the folded fabric can be easily pulled out, which is convenient for sewing. Similarly, when the fabric processing is finished, the placement plate 42 and the folding plate 43 can be laid flat and locked together by the positioning plate 6, so that the flipping mechanism 4 will not affect the processing of other fabric sewing methods.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
