Description

Technical Field

[0001] This utility model relates to the field of sewing equipment accessories, and in particular to a pull strip device for an overlock sewing machine. Background Technology

[0002] During garment sewing, the rolled-up binding edge needs to be pulled to the garment and then sewn together using a sewing machine. After sewing, the binding edge is cut off, completing one binding step. During the sewing process, workers need to repeatedly pull up the cut binding edge and attach it to the new garment. The binding edge is prone to curling during this process. If the binding edge is oriented incorrectly, the sewn garment needs to be reworked. Therefore, workers need to constantly monitor the curling of the binding edge and manually straighten it as soon as it is discovered, which greatly affects the workers' work efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model proposes a pull strip device for an overlock sewing machine, including a positioning piece 1, see reference. Figure 1 The positioning piece 1 is provided with a first positioning rod 11 and a second positioning rod 12 at intervals. Two first positioning parts 13 are slidably connected to the first positioning rod 11. The two first positioning parts 13 are spaced apart. The rolled edge is sleeved on the first positioning rod 11. The two first positioning parts 13 can limit the edge.

[0023] See Figure 2 , 3 A clamping assembly 2 is fixed on the second positioning rod 12. The clamping assembly 2 includes a clamping base plate 21, a clamping top plate 22, and several guide rods 23. The clamping top plate 22 and the clamping base plate 21 are respectively provided with several through holes, which are correspondingly arranged and connected. Two guide plates 24 are provided at intervals below the clamping base plate 21. The guide plates 24 are provided with guide pieces 241 and adjustment holes 242. The ends of the guide rods 23 pass through the through holes and the adjustment holes 242. During installation, the ends of the guide rods 23 move from bottom to top, passing through the guide pieces 241, the clamping base plate 21, and the clamping top plate 22 in sequence. The ends of the guide rods 23 are provided with anti-detachment blocks 25. An elastic element 26 is provided between the guide rods 23 and the clamping top plate 22. The elastic element 26 always generates a compressive force on the clamping top plate 22, the clamping base plate 21, and the guide pieces 241. The edge binding passes between the clamping top plate 22 and the clamping bottom plate 21. The two plates provide a clamping effect to prevent the edge binding from curling. At the same time, a channel is formed between the guide pieces 241 on the two guide plates 24. This channel can prevent the edge binding from sliding left and right during the pulling process, keeping the pulled edge binding in a straight state, which is convenient for workers to process.

[0024] In a specific embodiment, the guide rod 23 is a bolt, the anti-loosening block 25 is a nut, and the elastic element 26 is a spring. The spring is sleeved on the bolt, and its two ends abut against the nut and the clamping top plate 22, respectively. The nut is threaded to the end of the bolt to form a clamping assembly 2 with clamping force, achieving the effect of flattening and preventing winding of the edging. At the same time, the two guide plates 24 can move left and right along the adjustment hole 242 to adjust the distance between them to meet the needs of edging with different widths.

[0025] See Figure 1 The positioning plate 1 is also provided with a third positioning rod 14. The third positioning rod 14 can bear and tension the edge output from the clamping assembly 2, and prevent the edge that has been clamped and straightened from curling due to drooping. At the same time, the third positioning rod 14 is provided with two guide blocks 15. The edge passes through the gap between the guide blocks 15 to prevent the edge from sliding left and right during the pulling process. The guide block 15 is provided with a connecting sliding hole and a positioning screw hole. The third positioning rod 14 passes through the sliding hole. The positioning screw hole is provided with a fixing screw 151. The fixing screw 151 is screwed inward until it abuts against the third positioning rod 14, thereby fixing the position of the guide block 15 and the third positioning rod 14.

[0026] See Figure 1 A connecting block 16 is fixed on the positioning piece 1. The connecting block 16 has a connecting hole and a connecting screw hole. The end of the third positioning rod 14 is inserted into the connecting hole. A connecting screw 161 is provided in the connecting screw hole. The position of the third positioning rod 14 and the connecting hole is fixed by the connecting screw 161. The third positioning rod 14 is Z-shaped. The relative height of the bent end can be changed by rotating the third positioning rod 14, thereby changing its tension effect on the edge.

[0027] See Figure 2 The clamping base plate 21 is L-shaped, and the second positioning rod 12 is fixedly connected to the clamping base plate 21. The second positioning rod 12 can be replaced by a bolt, which is fixedly connected to the vertical end of the clamping base plate 21.

[0028] See Figure 1 The first positioning element 13 is a torsion spring steel strip, which is sleeved on the first positioning rod 11. The wound part of the torsion spring steel strip has a certain contraction force, so that its shell and the first positioning rod 11 are kept in a fixed position. When the user adjusts it, he can also push it to move by hand, which is convenient to operate.

[0029] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
