[0034] The present invention provides a garment sewing machine with precise positioning function, including a worktable 1 and a fixing component 3. The top of the worktable 1 is provided with a first support frame 2, the middle of the first support frame 2 is provided with a sewing device 21, and the sewing opening 22 is provided directly below the sewing device 21. The fixing component 3 is disposed on both sides of the worktable 1 and is slidably connected to the worktable 1. The fixing component 3 includes a second support frame 31, the top of the second support frame 31 is provided with a first cylinder 32, and the bottom of the first cylinder 32 is provided with a pressing member 5.

[0035] Place the fabric to be cut on the workbench 1, and then use the fixing components 3 on both sides to lower the first cylinder 32 and press the pressing piece 5 to press down on both sides of the fabric. Then start the sewing device 21 to work. The movement of the second support frame 31 drives the fabric to move, so that it will not shift and can be cut accurately.

[0036] According to some embodiments of the present invention, optionally, the fixing component 3 is provided with a sliding component 4 on each opposite side. The sliding component 4 includes a slide rail 41, in which a plurality of transverse rollers 42 are provided, and a sliding plate 43 is provided between each roller 42. Each sliding plate 43 is provided with a plurality of through holes 44. The fabric on both sides of the slide rail 41, under the action of the rollers 42, allows for better dragging. The through holes 44 allow air circulation and reduce dragging friction. The sliding plate 43 can be made of smooth stainless steel, and the rollers 42 should not protrude too much from the slide rail 41 to avoid vibration and displacement during dragging. The outer wall of the rollers 42 should be as horizontal as possible with the sliding plate 43.

[0037] According to some embodiments of the present invention, optionally, the worktable 1 is provided with slide rails 11 on both sides, and sliders 12 are provided on the slide rails 11. The sliders 12 are connected to the second support frame 31. The second support frame 31 can be moved by sliding the sliders 12 on the slide rails 11, and can be kept in a straight line for a limiting function.

[0038] According to some embodiments of the present invention, optionally, the pressing member 5 includes a first pressing block 51, the bottom of which is provided with a pressing groove 52, and a second pressing block 53 is provided in the pressing groove 52. The top of the second pressing block 53 is slidably connected to the pressing groove 52. A second cylinder 54 is provided on the side wall of the first pressing block 51, and the second cylinder 54 is connected to the second pressing block 53. The first pressing block 51 is lowered by the second cylinder 54, allowing the second pressing block 53 in the pressing groove 52 to press onto the fabric surface. The second pressing block 53 has a certain amount of room to move in the pressing groove 52. Then, the second cylinder 54 pushes the fabric in the direction of the second pressing blocks 53 on both sides, making the fabric taut for sewing. In addition, the second pressing block 53 is slidably connected to the pressing groove 52 to avoid displacement. The pressing member 5 can generally be in the shape of a long strip to increase its fixing range.

[0039] According to some embodiments of the present invention, optionally, the bottom of the second pressing block 53 is provided with a first anti-slip pad 55. This is to increase anti-slip properties and facilitate the movement of the fabric.

[0040] According to some embodiments of the present invention, optionally, the second pressing block 53 is provided with a plurality of grooves 56, each groove 56 is provided with a movable rod 57, and a spring 58 is provided between the movable rod 57 and the groove 56. The movable rod 57 passes through the first anti-slip pad 55. In order to avoid the slight protrusion of the roller 42, the movable rod 57 can be moved up and down in the groove 56 by the contraction of the spring 58 to press, so as to avoid the bulge of the roller 42 causing a certain gap between the fabric and the worktable 1 and displacement when pushing. Alternatively, the rollers 42 can be arranged adjacently without the need for the sliding plate 43 to separate them. This can also avoid the possibility that the front end of the fabric will get stuck on the outer wall of the roller 42 protrusion. The roller 42 protrusion means that the sliding plate 43 is on the same horizontal plane, and the outer wall of the roller 42 should be slightly convex to allow the fabric to contact the roller and slide.

[0041] According to some embodiments of the present invention, optionally, a connecting block 6 is provided on one side of the bottom of the pressing member 5, and a sliding groove 61 is provided directly below the connecting block 6, the sliding groove 61 being disposed on both sides of the worktable 1. In order to prevent the pressing member 5 from moving during movement, the connecting block 6 is used to limit its movement and increase its positioning accuracy.

[0042] According to some embodiments of the present invention, optionally, the bottom of the movable rod 57 is provided with a second anti-slip pad 59. This increases the friction between the movable rod 57 and the fabric.

[0043] According to some embodiments of the present invention, optionally, two blowers 7 are provided at the bottom of the workbench 1, and the blowers 7 are connected to the slide rail 41. The blowers 7 can blow air and suck air, allowing the fabric to be slightly lifted by blowing air through the through hole 44 to avoid contact with the workbench 1 as much as possible, thereby reducing friction and facilitating pushing. They can also suck air to increase the firmness of the fabric and prevent the fabric from shifting when dragging. The blowing power should not be too high to avoid blowing the fabric up and causing sewing displacement.

[0044] According to some embodiments of the present invention, optionally, the bottom of the worktable 1 is provided with support legs 8 to support the worktable 1 for operation.
