[0002] Clothing cutting is a clothing technology and process. It refers to the special treatment of the edge or joint of the fabric when cutting clothing, so as to make the clothing more beautiful and comfortable. The cutting can be divided into two types: straight cutting and curved cutting. Among them, the straight cutting is to cut the edge of the clothing in a straight line, which is usually used for the hem of the trousers, collar and cuffs. The straight cutting can make the edge of the clothing smoother and more regular, and it is also convenient for subsequent sewing work. Through reasonable cutting design and treatment, the edge and joint of the clothing can be made more beautiful, avoiding abrupt and uncoordinated feelings.

[0028] Specifically, the surface of the workbench 2 is smooth, which can reduce the resistance of the clothes during movement.

[0029] Further, a shift assembly 3 is connected between the inner walls on both sides of the workbench 2, and the shift assembly 3 includes a one-way screw 31 rotatably connected between the inner walls on both sides of the workbench 2, a first motor 32 is fixedly connected to one side of the workbench 2, an output shaft of the first motor 32 passes through the workbench 2 and is fixedly connected to the one-way screw 31, and a connecting block 33 is threadedly connected to the middle part of the one-way screw 31;

[0030] Specifically, the first motor 32 is controlled to drive the one-way screw 31 to rotate, and the one-way screw 31 threadably drives the connecting block 33 to move linearly, which can drive the square box 41, the positioning plate 5, and the pressing plate 64 to move synchronously. The pressing plate 64 pushes the clothing to move. While the clothing is moving, the overlocking machine body 1 runs, and the cut edges of the clothing can be sewed to prevent the cut edges from loosening during use.

[0031] Further, a distance-adjusting component 4 is connected between the two side grooves 21, wherein the distance-adjusting component 4 is arranged on the shifting component 3, and the distance-adjusting component 4 includes a square box 41 slidably connected between the two side grooves 21, an opening is arranged on the upper side of the square box 41, and a bidirectional screw rod 42 is rotatably connected between the inner walls on both sides of the opening, a second motor 43 is fixedly connected to one side of the square box 41, and an output end of the second motor 43 passes through the square box 41 and is fixedly connected to the bidirectional screw rod 42, and the outer sides of both ends of the bidirectional screw rod 42 are threadedly connected to positioning plates 5, and the bottom sides of the positioning plates 5 are slidably connected to the inner walls of the opening;

[0032] Specifically, the second motor 43 is controlled to drive the bidirectional screw rod 42 to rotate, and the bidirectional screw rod 42 threads drive the two positioning plates 5 to approach each other, so that the pressing plate 64 pushes the two sides of the garment cut to be completely aligned.

[0033] Furthermore, baffles 44 are fixed on the upper sides of both ends of the square box 41, and the distance between the two baffles 44 is consistent with the width of the workbench 2;

[0034] Specifically, the baffle 44 plays a limiting role, so that the square box 41 can move linearly along the direction of the workbench 2.

[0035] Further, the distance adjustment component 4 is provided with two positioning plates 5 with adjustable spacing, the positioning plates 5 pass through adjacent strip grooves 22 and are both installed with a pressing component 6, the pressing component 6 includes a fixing plate 61 fixed to one side of the positioning plate 5, a screw 62 is threadedly connected to the middle of the fixing plate 61, a knob 63 is fixedly connected to the top of the screw 62, a pressing plate 64 is rotatably connected to the bottom end of the screw 62, and the pressing plate 64 is kept in sliding connection with the side wall of the positioning plate 5;

[0038] Specifically, the rubber layer 65 can provide a certain buffer pressure, and the provision of the anti-slip protrusions can increase the friction force so that the clothing will not slip off.

[0039] Furthermore, there is a gap between the two pressing plates 64, and the gap is located below the head of the overlocking machine body 1;

[0040] Specifically, in the process that the two pressing plates 64 push the garment forward, the overlocking machine body 1 can sew the cut edges of the garment.

[0041] The construction steps of the overlock machine used to strengthen the firmness of the scissors edge of clothing are as follows:

[0042] Step 1: Lay one end of the garment flat on the workbench 2, and adjust the garment cut to be basically aligned with the head of the overlock machine body 1;

[0043] Step 2: Turn the knob 63, the knob 63 drives the screw 62 to rotate, and the screw 62 pushes the pressing plate 64 downward during the rotation, so that the two pressing plates 64 press the two sides of the clothing cut respectively. It is worth noting that when locking one side of the clothing cut, only one side of the clothing cut needs to be pressed;

[0044] Step 3: Control the second motor 43 to drive the bidirectional screw 42 to rotate, and the bidirectional screw 42 drives the two positioning plates 5 to move closer to each other, so that the pressing plate 64 pushes the two sides of the garment cut to be completely aligned;

[0045] Step 4: Control the first motor 32 to drive the one-way screw 31 to rotate, and the one-way screw 31 drives the connecting block 33 to move linearly, which can drive the square box 41, the positioning plate 5, and the pressing plate 64 to move synchronously. The pressing plate 64 pushes the clothing to move. While the clothing moves, the overlocking machine body 1 runs to sew the cut edges of the clothing, which can prevent the cut edges from loosening during use.

[0046] Step 5: After the sewing is completed, the second motor 43 and the first motor 32 run in the reverse direction to drive the pressing plate 64 to reset. The above steps are repeated to complete the sewing process of the longer garment cut.
