Figure Three ; Figure 5 yes Figure 2 Enlarged view of point A in the middle; Figure 6 yes Figure 3 A magnified view of point B in the middle. Please refer to [link / reference]. Figures 1 to 6 The diagram illustrates a preferred embodiment of a collar tension adjustment device for mounting on a double-needle sewing machine. It includes a drive mechanism 1, a sliding mechanism 2, a collar guide mechanism 3, an amplitude adjustment mechanism 4, an elastic element 5, a base plate 6, and a rotating plate 7. The sliding mechanism 2 and drive mechanism 1 are located on one side of the double-needle sewing machine, with the drive mechanism 1 connected to the sliding mechanism 2. A base plate 6 is located at the lower end of the double-needle sewing machine, and a rotating plate 7 is rotatably mounted on the base plate 6. The collar guide mechanism 3 is located on one side of the rotating plate 7. The amplitude adjustment mechanism 4 is mounted on the rotating plate 7 and the sliding mechanism 2. The elastic element 5 connects the collar guide mechanism 3 and the base plate 6. In this embodiment, see [reference needed]. Figure 2 As shown, both the drive mechanism 1 and the sliding mechanism 2 are mounted on the double-cart 10. The drive mechanism 1 drives the sliding mechanism 2, which in turn drives the amplitude adjustment mechanism 4 to swing at a certain frequency. This, in turn, drives the rotating plate 7 to swing, which in turn drives the collar guide mechanism 3 to swing back and forth, thereby achieving automatic stretching of the collar. This ensures that the collar is stretched evenly, freeing up employees' hands, reducing labor costs, and improving work efficiency. The elastic element 5 can be a spring, used to reset the collar guide mechanism 3.
[0029] Through the collar guide mechanism 3, the collar fabric can enter the collar guide mechanism 3 and then enter the bottom of the double-stitching machine 10, facilitating the sewing of the collar fabric by the double-stitching machine 10. The collar fabric can move automatically under the sewing of the double-stitching machine 10; this is prior art and will not be limited here. Since the double-stitching machine 10 is prior art, the structure of the double-stitching machine 10 given in this utility model is only a schematic diagram and is not intended to limit the structure of the double-stitching machine 10.
[0030] Furthermore, as a preferred embodiment, a fixing rod 8 is provided on the base plate 6, and one end of the elastic element 5 is connected to the fixing rod 8. The fixing plate is fixedly connected to the bottom, and an anti-detachment ring is provided at the upper end of the fixing rod 8 to prevent the elastic element 5 from detaching from the fixing rod 8. Both ends of the elastic element 5 are connected to the fixing plate and the collar guide mechanism 3 through connecting rings.
[0031] Furthermore, as a preferred embodiment, the sliding mechanism 2 includes a slide rail mounting block 21, a slide rail 22 is provided on one side of the slide rail mounting block 21, and a slider 23 is provided on the slide rail 22. The slide rail mounting block 21 is connected and fixed to the double-unit vehicle 10 by bolts, while the slide rail 22 can be connected to the slide rail mounting block 21 by screws, and the slider 23 can reciprocate on the slide rail 22.
[0032] Furthermore, in a preferred embodiment, the drive mechanism 1 includes a cylinder 11, a connecting rod 12, and a transmission rod 13. The cylinder 11 is mounted on a double-needle sewing machine. The piston rod of the cylinder 11 is connected to one end of the connecting rod 12, and the other end of the connecting rod 12 is connected to the transmission rod 13. The transmission rod 13 is connected to the slider 23. The connecting rod 12 and the transmission rod 13 are fixedly connected, and the transmission rod 13 and the slider 23 are fixedly connected. The cylinder 11 drives the connecting rod 12 to move the transmission rod 13, and the transmission rod 13 drives the slider 23 to reciprocate on the slide rail 22, thus providing a power source for the movement of the slider 23.
[0033] Furthermore, as a preferred embodiment, the amplitude adjustment mechanism 4 includes an amplitude adjustment block 41. The amplitude adjustment block 41 is disposed on the upper end of the rotating plate 7, and an inclined surface 42 is disposed on one side of the amplitude adjustment block 41. See also Figure 4 As shown, the inclined surface 42 is inclined from the left end to the right end in a direction away from the collar guide mechanism 3. The amplitude adjustment block 41 is fixedly connected to the rotating plate 7, which can drive the fixed plate to swing together.
[0034] Furthermore, as a preferred embodiment, it also includes a connecting rod 43, which passes vertically through the slider 23. A rotating ring 44 is provided at the lower end of the connecting rod 43, and the rotating ring 44 contacts the inclined surface 42. The rotating ring 44 is rotatably connected to the bracket of the connecting rod 43. An annular groove can be provided at the lower end of the connecting rod 43 for installing the connecting ring. The connecting ring contacts the inclined surface 42, and when the slider 23 moves, it can drive the connecting rod 43 to move, thereby driving the rotating ring 44 to move. Because the rotating ring 44 contacts the inclined surface 42, it can rotate when it moves, reducing the friction between it and the inclined surface 42. Because the inclined surface 42 is inclined, when the rotating ring 44 rolls on the inclined surface 42, it can push the amplitude adjustment block 41 to move. The amplitude adjustment block 41 drives the rotating plate 7 to rotate around the axis of rotation. Since the slider 23 drives the connecting rod 43 and the rotating ring 44 to move back and forth, and with the help of the elastic element 5, the rotating plate 7 can rotate back and forth, forming a reciprocating oscillating motion.
[0035] Furthermore, as a preferred embodiment, it also includes a rotating shaft 9, through which the rotating plate 7 and the base plate 6 are connected. The rotating shaft 9 and the rotating plate 7 are fixedly connected, while the rotating shaft 9 and the base plate 6 are rotatably connected. The rotating shaft 9 can support the rotating plate 7, allowing the rotating plate 7 to maintain a certain gap with the base plate 6.
[0036] Furthermore, as a preferred embodiment, the collar guiding mechanism 3 includes a direction adjusting mechanism 31 and a guide plate 32. One end of the guide plate 32 is connected to the direction adjusting mechanism 31, and the direction adjusting mechanism 31 is connected to the rotating plate 7. A guide groove is formed inside the guide plate 32. It also includes an arc-shaped plate 35. One end of the guide plate 32 has an inlet 33, and the other end has an outlet 34. Arc-shaped plates 35 are provided on one side of both the inlet 33 and the outlet 34. One side of the rotating plate 7 protrudes upward to form a connecting part, and the direction adjusting mechanism 31 is connected to the connecting part by bolts. Bolt holes for bolt engagement are provided on the connecting part. The guide plate 32 is hollow inside, forming a guide groove. One end of the collar can enter the guide groove through the inlet 33 and then exit through the outlet 34 into the bottom of the double-layer vehicle 10. The arc-shaped plate 35 can be found in [reference needed]. Figure 5 and Figure 6 As shown, it serves to guide the collar fabric and prevent the collar fabric from directly contacting the edges of the inlet 33 or outlet 34, thus avoiding wear.
[0037] Furthermore, as a preferred embodiment, the direction adjustment mechanism 31 includes a mounting plate 36, on which a first strip-shaped hole 37 and a second strip-shaped hole are formed. Bolts are installed in both the first strip-shaped hole 37 and the second strip-shaped hole. The length direction of the first strip-shaped hole 37 is perpendicular to the length direction of the second strip-shaped hole. (See also...) Figure 5 As shown, there are two first strip-shaped holes 37 and one second strip-shaped hole. A third strip-shaped hole 38 is provided at one end of the guide plate 32, which is directly opposite to the second strip-shaped hole. After the bolt passes through the second strip-shaped hole and the third strip-shaped hole 38, it is connected to the connecting part. By cooperating with the bolt and the first strip-shaped hole 37, the vertical position of the mounting plate 36 can be adjusted, thereby adjusting the height of the guide plate 32. By setting the bolt, the second strip-shaped hole and the third strip-shaped hole 38, the horizontal position of the guide plate 32 can be adjusted so that the collar fabric can smoothly enter the bottom of the double-piece sewing machine 10 for sewing.
[0038] In this embodiment, the working frequency of the cylinder 11 can be the same as that of the double-stitching machine 10. That is, when the double-stitching machine 10 sews a thread once, the piston rod of the cylinder 11 extends and retracts once, so that the collar guide mechanism 3 can swing back and forth once, so that the collar is in an automatic stretching state during the stitching process of the double-stitching machine 10.
[0039] In use, one end of the collar fabric is passed through the inlet 33, the guide groove and the opening and then into the bottom of the double-stitching machine 10. The collar fabric is sewn by the double-stitching machine 10. During the sewing process, the cylinder 11 is activated at the same time. The cylinder 11 drives the slider 23 to move back and forth on the slide rail 22 through the connecting rod 12 and the transmission rod 13. This drives the connecting rod 43 and the rotating ring 44 to move back and forth, so that the amplitude adjustment block 41 can drive the rotating plate 7 to swing. With the setting of the elastic element 5, the rotating plate 7 can swing back and forth, thereby driving the guide plate 32 to swing back and forth, thus realizing the automatic stretching of the collar fabric.
[0040] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
