Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figure 1-8 , the present utility model provides a technical solution: a stretching device for sewing thread production, including a base 1, moving wheels 2, side plates 3, adjusting bolts 4, bearing plates 5, servo motors 6, stretching turntables 7, supporting balls 8, supporting tracks 9, fixing grooves 10, movable plates 11, fixing rods 12, springs 13, limiting plates 14, fixed sleeves 15, connecting rods 16, wire winding mechanisms 17, wire winding rollers 18, movable baffles 19 and fastening bolts 20.

[0035] When using the stretching device for sewing thread production, as Figure 1 and Figure 2 shown, moving wheels 2 are fixedly installed at the lower end of the base 1. First, the device is driven by the moving wheels 2 to move to the corresponding processing position. After reaching the corresponding position, by rotating the adjusting bolt 4 threadedly connected to the middle of the side plate 3, and the lower end of the adjusting bolt 4 is rotatably connected to the bearing plate 5, the adjusting bolt 4 drives the bearing plate 5 to move up and down telescopically, so that the bearing plate 5 is directly placed on the ground. Through the settings of the adjusting bolt 4 and the bearing plate 5, and the bearing plate 5 is symmetrically arranged on the left and right sides at the lower end of the base 1, thereby facilitating the auxiliary support of the base 1 and improving the stability of the device during use;

[0036] After fixation, as Figure 4 ,Figure 5 , Figure 6 and Figure 7 As shown in Figure 5 , Figure 6 , and Figure 7 , in the middle of the upper end of the stretching turntable 7, a support track 9 is fixedly connected. The movable plates 11 are symmetrically arranged and slide on the left and right sides of the support track 9. The movable plates 11 are connected to the support track 9 by a card slot. Moreover, a wire winding mechanism 17 is provided at the upper end of the movable plates 11. At the same time, the wire winding mechanism 17 includes a wire winding roller 18 fixedly connected to the upper end of the movable plate 11, a movable baffle 19 sleeved on the outer surface of the wire winding roller 18, and a fastening bolt 20 for limiting. First, by pulling the movable plate 11, the movable plate 11 slides between the support track 9. By sliding between the movable plate 11 and the support track 9, the distance between the wire winding rollers 18 on the left and right sides can be adjusted, and the tension of the sewing thread during stretching can be adjusted according to actual stretching requirements.

[0037] After the adjustment is completed, by rotating the fixing sleeve 15 threadedly connected to the outer surface of the fixing rod 12, the lower end of the fixing sleeve 15 is in close contact with the limiting plate 14. The fixing sleeve 15 pushes the limiting plate 14 to slide between the fixing rod 12. The limiting plate 14 moves downward, and connecting rods 16 are fixedly connected to the front and rear ends of the limiting plate 14. The connecting rods 16 are connected to the fixing rod 12 by a card slot. By driving the connecting rods 16 to slide between the fixing rod 12 through the limiting plate 14, the stability of the movement between the limiting plate 14 and the fixing rod 12 is improved. Moreover, fixing grooves 10 are equally spaced at the upper end of the support track 9. The limiting plate 14 moves downward and is engaged in the fixing grooves 10 at corresponding positions, thereby facilitating the fixation between the movable plate 11 and the support track 9. After the fixation is completed, according to the actual winding amount of the sewing thread, by pulling the movable baffle 19, the movable baffle 19 slides between the wire winding roller 18, thereby facilitating the adjustment of the winding length of the wire winding roller 18. When adjusted to the corresponding position, the movable baffle 19 and the wire winding roller 18 are limited by the fastening bolt 20.

[0038] After all the adjustments are completed, as shown in Figure 1 , Figure 2 , and Figure 3 , the stretched sewing thread is passed through the through groove in the middle of the wire winding roller 18 and tied to the wire winding roller 18 on one side of the upper end of the support track 9. Then, the device is powered on and the servo motor 6 installed in the middle of the base 1 is started. The servo motor 6 drives the stretching turntable 7 to rotate on the upper end of the base 1, so that the sewing thread is wound around the wire winding rollers 18 on the left and right sides, thereby driving the wire winding roller 18 to rotate to realize the stretching operation of the sewing thread. Moreover, the stretching turntable 7 and the support balls 8, as well as the support balls 8 and the base 1, are all connected by a card slot. By rolling the support balls 8 between the stretching turntable 7 and the base 1, it is convenient to support the stretching turntable 7, and the stability is good.
