Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1-8 As shown, a thread cutting device according to one embodiment of this utility model includes two frames 1, each rotatably connected to a thread winding frame 2. Multiple thread winding rollers 3 are detachably installed between the two thread winding frames 2, forming a thread winding roller. With the assistance of a thread guide (not shown), the thread can be evenly and regularly distributed on the thread winding roller. A motor 4 is installed on one side of one of the thread winding frames 2, driving one of the thread winding frames 2 to rotate, and the power is transmitted to the other thread winding frame 2 by the thread winding roller 3. The cooperation between the winding roller and the thread guide to achieve even and regular thread distribution is common knowledge in the art.

[0031] like Figures 1-8 As shown, a wetting mechanism and a shearing mechanism are installed inside the sewing roller. The wetting mechanism can wet the part of the sewing thread that is cut by the shearing mechanism to reduce the friction caused by the shearing mechanism during the shearing process. This reduces the twisting, knotting or fraying of the sewing thread at the cut point due to dryness, which helps to improve the flatness of the sewing thread at the cut point, makes it easier to insert the sewing thread into the needle, facilitates the combination of sewing thread and needle, and improves the production efficiency of sewing thread.

[0032] Specifically, such as Figures 1-8As shown, the wetting mechanism and the shearing mechanism are both mounted on the first mounting plate 5, and the wetting mechanism and the shearing mechanism are arranged adjacent to each other. The shearing mechanism includes a shearing structure 13, which can be a scissors in particular, and the shearing of the suture can be realized through the scissors. In order to further improve the flatness of the suture shearing part, a third sliding groove 501 is formed on the first mounting plate 5, a third sliding block 11 matched with the third sliding groove 501 is slidingly connected to the first mounting plate 5, a second mounting plate 12 is fixedly connected to the third sliding block 11, and a waist hole 1201 is formed on the second mounting plate 12. One side of the shearing structure 13 is fixedly connected with a connecting column 14 matched with the waist hole 1201, the connecting column 14 is slidingly connected inside the waist hole 1201, and a nut 15 for fastening the shearing structure 13 and the second mounting plate 12 is fixedly connected to the connecting column 14. By slidingly connecting the connecting column 14 up and down, the height of the shearing structure 13 can be adjusted, so that the height of the shearing structure 13 can match the position of the suture, and the shearing structure 13 slides along the direction in which the third sliding groove 501 is formed. The shearing extension line of the shearing structure 13 is in a perpendicular state with the suture, and the shearing is performed in this state, which can greatly improve the flatness of the suture shearing part.

[0033] As shown in Figures 1-8 The first mounting plate 5 is fixedly connected with a U-shaped sliding groove 504 at both ends of the third sliding groove 501, the U-shaped sliding groove 504 has a groove matched with the third sliding groove 501, and the third sliding block 11 is slidingly connected in the U-shaped sliding groove 504. At this time, the shearing structure 13 does not affect the winding of the suture on the suture winding roller.

[0034] As shown in Figures 1-8 The wetting mechanism includes a water tank 6, the water tank 6 is fixedly connected with a baffle 8, the water tank 6 and the baffle 8 cooperate to form a first cavity 7, water is stored in the first cavity 7, and if the water contacts the suture, the suture can be wetted, which is beneficial to the shearing of the suture by the shearing mechanism. The baffle 8 is fixedly connected with a water absorbing part 9, the water absorbing part 9 is installed with a water absorbing rope 10 connected with the first cavity 7, one end of the water absorbing rope 10 is fixedly connected with the water absorbing part 9, and the other end is located inside the first cavity 7. The materials of the water absorbing part 9 and the water absorbing rope 10 can both be cotton, which has a water absorbing effect, can absorb water in the first cavity 7, and can make the suture contact the water absorbing part 9 to realize the wetting of the suture.

[0035] Specifically, the water absorbing part 9 and the suture are in interference fit, and when the suture is wound on the suture winding roller, part of the suture will be pressed on the water absorbing part 9, and the water absorbing part 9 will transfer the absorbed water to the suture to realize the wetting of the suture.

[0036] In order to obtain sutures of different specifications, as shown in Figures 1-8As shown, the position of the thread winding roller 3 on the thread winding frame 2 is adjustable, and the first mounting plate 5 can also be adjusted according to the position of the thread winding roller 3. The thread winding frame 2 has a first sliding groove 201, and a first fastener 16 is threadedly connected to the thread winding roller 3. The first fastener 16 passes through the first sliding groove 201 and is threadedly connected to the thread winding roller 3. Loosening the first fastener 16 allows the thread winding roller 3 to slide along the first sliding groove 201, and tightening the first fastener 16 can fix the thread winding roller 3 and the thread winding frame 2.

[0037] like Figures 1-8 As shown, a first slider 502 matching the first slide groove 201 is fixedly connected to the first mounting plate 5. A second slide groove 203 is also provided on one side of the first slide groove 201, and a second slider 503 matching the second slide groove 203 is fixedly connected to the first mounting plate 5. The cooperation of the first slider 502 and the second slider 503 allows the first mounting plate 5 to slide along the first slide groove 201 without easily causing the first mounting plate 5 to shift. A threaded hole 5021 matching the first slide groove 201 is provided on the side of the first slider 502. A second fastener 17 matching the threaded hole 5021 is threadedly connected to the first slider 502. The second fastener 17 passes through the first slide groove 201 and is threadedly connected to the threaded hole 5021. By changing the tightness of the second fastener 17 and the threaded hole 5021, the locking and unlocking states of the first mounting plate 5 are changed, thereby achieving adjustment of the position of the first mounting plate 5.

[0038] like Figures 6-7 As shown, the suture winding frame 2 has several evenly distributed positioning grooves 202. The positioning grooves 202 are used as preset grooves. The interval between each positioning groove 202 is 10cm. The length of the suture segment after cutting can be roughly determined through the positioning grooves 202.

[0039] When using, such as Figures 1-8 As shown, first, confirm the length of a single thread, and adjust the outer diameter of the thread winding roller accordingly. Loosen the first fastener 16 to allow the thread winding roller 3 to slide within the first groove 201, thus adjusting its position. After adjusting the outer diameter, tighten the first fastener 16. Then, regularly and evenly wind the thread onto the thread winding roller. During winding, the water-absorbing part 9 contacts the thread to wet it. After winding, use the shearing structure 13 to cut the thread. After cutting one thread, the shearing structure 13 moves forward, allowing the third slider 11 to slide within the third groove 501 to cut the next thread, continuing until all threads are cut. Thus, the shearing structure 13 remains perpendicular to the thread, ensuring the flatness of the cut and facilitating insertion of the thread into the needle.
