[0002] The overlock machine is also called the lock-edge machine. During the clothing production process, the threads on the edges of the cut fabrics are loose, and are prone to unraveling and falling off. Therefore, the cut fabrics are usually overlocked. The overlock machine overlocks a circle of edge stitching on the edge of the fabric to prevent the threads in the fabric from unraveling, while also making the fabric look beautiful.

[0003] Most of the current overlock machines are installed on the tray through the workbench with screws, and the height and inclination of the overlock machines are fixed. When the operator uses it, the head is much higher than the overlock machine, and the line of sight is blocked by the overlock machine, making it difficult to observe the overlock needle position, which is prone to skewed overlocks. The user can only observe by lowering his head, which is not conducive to the healthy development of the user's cervical spine; in addition, when performing this operation, the alignment of the upper and lower fabrics and the overlock position on the fabric are usually manually adjusted, and the fabric is often uneven and the edge is cut too much, resulting in the fabric after overlocking not meeting the expected size. Utility Model Content

There are four feet 5, which are symmetrically distributed at the bottom of the base 4. A screw hole 18 is opened at the bottom of the foot 5. An adjusting rod 19 is arranged inside the screw hole 18. The adjusting rod 19 is used to adjust the base 4 and the overlocking machine relative to the tray 6. Lifting and lowering, a knob 21 is connected to the bottom of the adjusting rod 19, a bearing 20 is connected between the adjusting rod 19 and the tray 6, a front fixing seat 9 is connected to the front side of the machine plate 3, the front fixing seat 9 is welded and fixed to the front side of the machine plate 3, a rear fixing seat 10 is connected to the rear side of the machine plate 3, the rear fixing seat 10 is welded and fixed to the overlocking machine body 1 below the machine plate 3, baffles 11 are connected to the tops of the front fixing seats 9 and the rear fixing seats 10, the baffles 11 are perpendicular to the front fixing seats 9 and the rear fixing seats 10, and dust hoods 12 are connected to the side walls of the front fixing seats 9 and the rear fixing seats 10, the dust hood 12 is used for both absorbing dust particles on the surface of the fabric and supporting the fabric to be neatly overlocked.

[0022] Specifically, rubber pads 7 are provided on the upper surfaces of both sides of the tray 6, screws 8 are penetrated on both sides of the tray 6, and the two sides of the tray 6 are connected to the workbench 2 via the screws 8. The screws 8 penetrate the tray 6 and the rubber pads 7 in turn and drill into the workbench 2 to install the tray 6 at the bottom of the workbench 2.

[0023] Furthermore, there are four adjusting rods 19, which are symmetrically distributed at the four corners of the tray 6. The adjusting rods 19 pass through the tray 6. The surface of the adjusting rods 19 is provided with threads. The outer diameter of the adjusting rods 19 is matched with the inner diameter of the screw hole 18. The adjusting rods 19 are inserted into the screw hole 18 and are threadedly connected to the base 5. The adjusting rods 19 are rotatably connected to the tray 6 via the bearing 20. The knob 21 drives the adjusting rods 19 to rotate. The adjusting rods 19 rotate in the tray 6 via the bearing 20, and drive the base 5 to rise and fall via the threads. The base 5 drives the base 4 to rise and fall, and the base 4 drives the main body 1 of the overlocking machine to rise and fall, thereby realizing the fine height adjustment and inclination adjustment functions of the overlocking machine.

[0024] Furthermore, the dust hood 12 is U-shaped, and a negative pressure chamber 15 is arranged inside the dust hood 12. Dust suction holes 16 are opened through the upper side wall of the dust hood 12. There are several dust suction holes 16, which are arranged equidistantly.

[0028] The method of using the present embodiment is as follows: when the user actually uses the overlock machine to sew and overlock two pieces of fabric, the user will first turn the knob 21 from below the tray 6, the knob 21 drives the adjusting rod 19 to rotate, the adjusting rod 19 rotates in the tray 6 via the bearing 20, and drives the foot 5 to rise and fall via the thread, the foot 5 drives the base 4 to rise and fall, the base 4 drives the overlock machine body 1 to rise and fall, adjust the height of the overlock machine body 1, and control the height difference between the front and rear foot 5, so that the overlock machine body 1 forms an inclined shape with the front higher and the back lower, so that the overlock needle is not blocked by the overlock machine body 1 at the front, and the operator can observe the overlock situation conveniently, and then overlap the two pieces of fabric up and down, pass the fabric between the pressing wheel 14 and the dust cover 12, the pressing wheel 14 presses the fabric on the upper surface of the upper fabric, An external vacuum pump is connected through the suction pipe 17. When the vacuum pump is turned on, suction is conducted to the negative pressure chamber 15 through the suction pipe 17, so that a negative pressure state is formed in the negative pressure chamber 15. The dust suction holes 16 generate suction force to absorb dust and impurities on the surface of the fabric. At the same time, the air suction force generated by the dust suction holes 16 absorbs and positions the lower fabric. The upper fabric is positioned by squeezing by the pressing wheel 14. The dust hood 12 and the pressing wheel 14 are clamped to ensure that the two layers of fabric entering the overlock are aligned. The baffle 11 limits one side of the fabric to prevent excessive cutting of the edge of the fabric. The user can continuously adjust the fabric overlap and push the fabric overlock on the front side of the dust hood 12. The fabric after overlocking passes through between the dust hood 12 and the pressing wheel 14 on the rear side, and the dust generated by the overlocking and cutting of the fabric is absorbed by the dust hood 12 on the rear side.
