Description

Technical Field

[0002] Small overlock sewing machines are a general term for household overlock sewing machines, also known as overlock machines. The main function of overlock sewing machines is generally to prevent the seams of fabrics and leathers from fuzzing. As we all know, in order to achieve better overlocking effects, overlock machines are equipped with positioning devices. However, the positioning effects of existing overlock machines are not good, so that the overlock machines cannot effectively position fabrics and leathers during use, causing the lines of fabrics and leathers to deviate during overlocking, and the overlocking results become not very neat and beautiful, which reduces the sales quality of the overlocking results.

[0003] For example, a positioning device for an edge binding machine disclosed in a Chinese patent document (publication number: CN214613010U) improves the stability of cloth edge binding through the coordinated use of a fixed seat, a through hole, a fixed rod, a support seat, a positioning plate, an adjustment cylinder, a sliding rod, a slider, a machine body, a spring, a fixed plate, a fixed groove, a sleeve rod, a vertical plate and an anti-skid pad. However, when edge binding leather, since the device is not convenient for adjusting the height of the positioning plate, when conveying thicker leather, the pressure is relatively large, which is not conducive to conveying, and tools are needed to remove the bolts during maintenance, which makes the operation more cumbersome.

The two side surfaces of the mounting block 73 are provided with symmetrically distributed movable grooves 74, one end of the movable groove 74 is connected to one end of the card slot 6, and the inner wall of the movable groove 74 is movably sleeved with an inclined card block 75. The pressing block 72 facilitates the pressing and moving of the connecting rod 71 and limits the moving stroke of the connecting rod 71.

[0025] Furthermore, the outer surface of one end of the inclined clamping block 75 is movably plugged into the inner wall of the clamping slot 6, and one end of the inclined clamping block 75 contacts the other side surface of the extrusion plate 7. The other end of the inclined clamping block 75 is fixedly connected with a reset spring 76, and the reset elastic force of the reset spring 76 drives the inclined clamping block 75 to reset and move.

[0026] Furthermore, one end of the return spring 76 is fixedly connected to the inner wall of one side of the movable groove 74, a receiving groove 77 is provided on the upper surface of the mounting block 73, and an annular slide groove 78 is provided on the upper surface of the mounting block 73. The inner wall of the annular slide groove 78 is slidably connected with arc-shaped sliders 79 distributed in an annular array, and the arc-shaped slider 79 plays the role of limiting sliding on the inner wall of the annular slide groove 78.

[0027] Furthermore, the upper surfaces of the multiple arc-shaped sliders 79 are fixedly connected with threaded rings 710, the lower surfaces of the threaded rings 710 are in contact with the upper surface of the mounting block 73, the inner wall of the threaded ring 710 is threadedly connected with a screw rod 711, one end of the screw rod 711 extends to the interior of the storage groove 77, and the arc-shaped sliders 79 cooperate with the threaded ring 710 for positioning and rotation.

The height of the positioning plate 1 can be adjusted, thereby facilitating the positioning and transportation of leathers of different thicknesses, avoiding deviation during hemming, and thus improving the quality of subsequent hemming.

[0030] Working principle: Step 1, during installation, firstly, the positioning plate 1 is sleeved and positioned through the guide sleeve 714 and the rectangular guide rod 713, and then moved upward, so that the mounting block 73 is inserted into the slot 5. During insertion, the inclined surface of the inclined surface block 75 will be squeezed with the inner wall of the slot 5, so that it drives the return spring 76 to contract. When fully inserted, the movable slot 74 is connected with the slot 6, and the return elastic force of the return spring 76 drives the inclined surface block 75 to be inserted into the slot 6, and squeezes the extrusion plate 7, so that the extrusion plate 7 drives the pressing block 72 to move through the connecting rod 71;

[0031] Step 2: When adjusting, if the positioning plate 1 needs to be driven to move upward, the threaded ring 710 is rotated clockwise. The rotation of the threaded ring 710 is positioned and rotated through the cooperation of the annular slide groove 78 and the arc-shaped slider 79, and the screw rod 711 is cooperated to drive the positioning plate 1 to move upward through the mounting block 73. Conversely, when the threaded ring 710 is rotated counterclockwise, the positioning plate 1 is driven to move downward.

[0032] Step three, during disassembly, by pressing the two pressing blocks 72 synchronously, the pressing block 72 drives the extrusion plate 7 to move through the connecting rod 71, and the movement of the extrusion plate 7 squeezes the inclined block 75, causing it to drive the return spring 76 to retract, and when the pressing block 72 moves to contact one side of the mounting block 73, the inclined block 75 disengages from the slot 6, and finally the positioning plate 1 is pulled downward to make the mounting block 73 disengage from the slot 5 to complete the disassembly.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
