[0001] The utility model relates to the technical field of industrial sewing machines, and particularly relates to an industrial sewing machine convenient for replacing wire materials. Background Technique

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so as to interweave or sew together one or more layers of sewing materials. The sewing machine can sew fabrics such as cotton, linen, silk, wool, and artificial fibers, as well as products such as leather, plastic, and paper. The stitches sewn are neat, beautiful, flat and firm, with the characteristics of fast sewing speed and easy use. An industrial sewing machine is suitable for sewing workpieces used in large-scale production in sewing factories or other industrial departments. Factories that need sewing machines for clothing, shoes, hats, etc. all use industrial sewing machines.

[0003] At present, industrial sewing machines are widely used. Although the existing industrial sewing machines can meet the needs of production processes, since the bobbin thread of the existing industrial sewing machines is installed under the needle plate, and the needle plate is installed under the needle, it is not easy to disassemble, which will be affected by the needle and the needle plate when replacing the bobbin thread, thus bringing inconvenience to the operation of the staff. Moreover, when replacing the wire material, the wire end needs to be inserted into the opening of the needle head. However, since the wire material is relatively soft and the opening of the needle head is small, it takes a long time to insert the wire material into the needle head, thereby reducing the production efficiency.

[0026] The needle plate base assembly 7 includes a groove 702 formed inside the base 1. Inside the groove 702, there is a needle plate base body 701. The needle plate base body 701 is inserted into the groove 702 and slides therein. The adjusting assembly 8 includes a toothed plate 801 fixed to the outside of the needle plate base body 701. The toothed plate 801 is fixedly installed on one side of the needle plate base body 701. Inside the base 1, there is a gear 802. Inside the gear 802, there is a rotating rod 803. The rotating rod 803 is rotatably connected in the base 1. The gear 802 is fixedly installed on the rotating rod 803. In the base 1, there is a receiving groove for accommodating the gear 802. On the outside of the toothed plate 801, there is a latch 804, and inside the groove 702, there is a card slot. By rotating the rotating rod 803 to drive the gear 802 to rotate, the gear 802 meshes with the toothed plate 801 on the needle plate base body 701, driving the needle plate base body 701 to move in the groove 702. When the gear 802 is rotated clockwise, the latch 804 on the needle plate base body 701 is engaged in the card slot, thus closing the groove 702. When the gear 802 is rotated counterclockwise, the needle plate base body 701 is opened to take out the inner bobbin thread for quick replacement. Through the meshing of the gear 802 and the toothed plate 801, and the engagement of the latch 804 and the card slot, the needle plate base body 701 will not be easily opened, which may affect the use of the sewing machine.

[0027] The thread threading assembly 6 includes a sleeve 601 disposed in the storage case 9. The sleeve 601 is fixedly installed in the storage case 9. Inside the sleeve 601, there is a connecting rod 602. The connecting rod 602 is inserted into the sleeve 601. On the outside of the connecting rod 602, there is a sleeve 603.

The limiting block 12 is fixedly installed on the needle plate base body 701 and on the side symmetrical to the toothed plate 801. Inside the groove 702, there is a limiting groove. When the needle plate base body 701 moves, it drives the limiting block 12 to move in the limiting groove, thereby improving the stability of the needle plate base body 701.

[0029] Working principle: Rotating the rotating rod 803 drives the gear 802 to rotate. The gear 802 meshes with the toothed plate 801 on the needle plate base body 701, driving the needle plate base body 701 to move in the groove 702. When the gear 802 is rotated clockwise, the latch 804 on the needle plate base body 701 is engaged in the card slot, thereby closing the groove 702. Rotating the gear 802 counterclockwise opens the needle plate base body 701 to take out the bobbin thread inside for quick replacement. Through the meshing of the gear 802 and the toothed plate 801, and the engagement of the latch 804 and the card slot, the needle plate base body 701 will not be easily opened, which affects the use of the sewing machine. When threading the thread through the needle 4, open the cover plate 10, pull out the connecting rod 602 from the sleeve 601, then turn over the sleeve 603 to pull out the plug rod 604, then thread the thread through the elastic steel strip 605, and then insert the elastic steel strip 605 and the thread together into the needle 4. Since the elastic steel strip 605 is rigid, it can be quickly inserted into the opening of the needle 4, thereby inserting the thread into the needle 4. Then, hold the thread and pull out the elastic steel strip 605. After threading, the threading assembly 6 can be stored in the storage case 9, which will not affect the use of the sewing machine.
