[0021] Figure 4 for Figure 2 The enlarged schematic diagram of part A is shown. The thread trimming mechanism of the high-speed vertical cylinder interlock sewing machine comprises: an interlock sewing plate 1, a thread trimming plate 2 is fixedly connected to the bottom of the interlock sewing plate 1, a thread trimming cylinder 3 is installed at the bottom of the thread trimming plate 2, a telescopic rod 4 is slidably connected to the right end of the thread trimming cylinder 3, and two V-shaped belt line pieces 5 are fixedly connected to the other end of the telescopic rod 4, a shearing groove 6 is provided on the telescopic rod 4, and two thread trimming blades 7 are rotatably connected inside the shearing groove 6, and the thread trimming blade 7 is provided with a rotating shaft 8, and a rotating plate 9 is fixedly connected to the rotating shaft 8, and a torsion spring is fixedly connected between the two rotating plates 9. Spring 20, a guide roller 11 is installed on the thread cutting blade 7, a guide plate 12 is fixedly connected to the bottom of the thread cutting plate 2, a guide groove 13 is provided on the guide plate 12, two constraint plates 14 are fixedly connected to the bottom of the thread cutting plate 2, constraint grooves 15 are provided on the two constraint plates 14, and a threading hole 16 is provided on the sewing plate 1. The thread cutting mechanism of the high-speed vertical cylinder sewing machine can effectively prevent the thread head from escaping from the needle hole when cutting the thread, reduces the time waste caused by re-threading, greatly improves the production efficiency, and makes the sewing work smoother.

[0022] A material receiving bin 17 is clamped at the bottom of the constraint plate 14, and a mounting mechanism 18 is arranged on the material receiving bin 17. A mounting hole 19 is opened on the constraint plate 14, and a mounting plate 20 is arranged on the mounting mechanism 18. A mounting spring 21 is fixedly connected inside the mounting plate 20, and a slide plate 22 is fixedly connected to the other end of the mounting spring 21. A slide groove 23 is opened on the mounting plate 20, and a clamping column 24 is fixedly connected to the slide plate 22. After cutting the thread ends, more or less small broken ends will appear, and these broken ends will fall into the material receiving bin 17. There is water in the material receiving bin 17, and the broken ends will not rise again after falling into it. After pressing the clamping column 24, the clamping column 24 retracts into the mounting plate 20, and the mounting hole 19 can no longer constrain the clamping column 24, so that the material receiving bin 17 can be easily removed for waste cleaning.

[0023] The thread cutting plate 2 is provided with a through slot 25, and a fastener 26 is threadedly connected to the thread cutting plate 2. The thread cutting plate 2 can be installed inside the interlock sewing machine through the fastener 26 without disturbing the normal operation of the interlock sewing machine.

[0024] The left side of the thread trimming cylinder 3 is fixedly connected with a first air pipe 27 , and the right side of the thread trimming cylinder 3 is fixedly connected with a second air pipe 28 . The first air pipe 27 and the second air pipe 28 can inlet and outlet air to complete the extension and retraction of the telescopic rod 4 .

[0025] The V-shaped belt line piece 5 is provided with an anti-skid pad 29 , the material of the anti-skid pad 29 is rubber, and the anti-skid pad 29 can prevent the suture from sliding.

[0026] A controller 30 is installed on the thread trimming plate 2 . The controller 30 is electrically connected to the thread trimming cylinder 3 . The controller 30 controls the start and stop of the thread trimming cylinder 3 .

[0027] The working principle of the thread cutting mechanism of the high-speed vertical cylinder interlock sewing machine provided by the utility model is as follows:

[0028] The suture will pass through the threading hole 16 for sewing. When the thread needs to be trimmed, the thread trimming cylinder 3 is started, the telescopic rod 4 is extended, the suture is stuck in the thread groove in the V-shaped belt thread piece 5, and the thread trimming blade 7 also moves at the same time. The thread trimming blade 7 first enters the guide plate 12 through the guide roller 11 and the guide groove 13, and finally enters the constraint plate 14. At this time, the V-shaped belt thread piece 5 has brought the suture out of the needle for a part of the distance. At this time, it moves into the constraint plate 14. Since the two constraint plates 14 form a shape that is wide on the left and narrow on the right, the thread trimming blades 7 are close to each other, and the thread trimming is finally completed. After the telescopic rod 4 is retracted, the thread trimming blade 7 is opened again by the torsion spring 10 to perform the next thread trimming. Since the suture has been brought out of the needle for a part of the distance, the thread head can be effectively prevented from detaching from the needle hole, reducing the time waste caused by rethreading.

[0029] Compared with the related art, the thread cutting mechanism of the high-speed vertical cylinder interlock sewing machine provided by the utility model has the following beneficial effects:

[0030] The thread trimming mechanism of the high-speed vertical cylinder interlock sewing machine can effectively prevent the thread ends from falling out of the needle holes when trimming the thread, reducing the time wasted due to rethreading, greatly improving production efficiency, and making sewing work smoother. By collecting the small thread scraps generated during thread trimming and dropping them into the water tank, the small thread scraps are prevented from flying up and polluting the working environment, thus keeping the workplace clean and tidy, which is beneficial to the health of the workers. The water tank is easy to install and clean, greatly facilitating the workers' operation, reducing maintenance time and workload, and keeping the equipment in good operating condition at all times.
