[0017] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0019] like Figure 1-2 The diagram illustrates a preferred embodiment of a rope knotting machine, comprising: a worktable 1, a sewing machine 2, a first cylinder 3, a second cylinder 4, and a first rotary motor 5. The sewing machine 2 is disposed in the center of the worktable 1, the first cylinder 3 is disposed on one side of the sewing machine 2, the second cylinder 4 is connected to the output end of the first cylinder 3, and the first rotary motor 5 is connected to the output end of the second cylinder 4. Further, the first cylinder 3 can extend or retract in a first direction, and the second cylinder 4 can extend or retract in a second direction.

[0020] Furthermore, in a preferred embodiment, both the first direction and the second direction are horizontal, and the first direction and the second direction are perpendicular to each other.

[0021] Furthermore, as a preferred embodiment, it also includes: a connecting plate, the lower end of which is connected to the output end of the first cylinder 3, and the second cylinder 4 is connected to the upper end of the connecting plate.

[0022] Furthermore, as a preferred embodiment, the output end of the first rotary motor 5 is provided with a clamp 6. The clamp 6 includes a connecting part and a clamping part. The connecting part connects the output end of the first rotary motor 5 and the clamping part. One end of the clamping part is bolted to the connecting part. The other end of the clamping part is provided with two fixing grooves 61. The rope that needs to be knotted can be placed in the fixing grooves 61, and the rope can be stably present in the fixing grooves 61 without slipping.

[0023] Furthermore, as a preferred embodiment, it also includes: a limiting device, which is disposed below the sewing machine 2 and is rotatably connected to the worktable 1.

[0024] Furthermore, as a preferred embodiment, the sewing machine 2 is provided with a pressing device, which is connected to the sewing machine 2.

[0025] Furthermore, as a preferred embodiment, it also includes a connecting seat 7, a base plate 8, and a second rotary motor. The connecting seat 7 is located at the lower end of one side of the sewing machine 2, and the lower end of the connecting seat 7 is connected to the output end of the second rotary motor. The second rotary motor is located inside the worktable 1. A pressing device is provided at one end of the connecting seat 7, and a base plate 8 is provided below the connecting seat 7. The base plate 8 is rotatably connected to the worktable 1.

[0026] Furthermore, in a preferred embodiment, the limiting device includes: a fixed plate 11, a limiting plate 12, and a positioning bolt. The fixed plate 11 is disposed on the base plate 8, and two limiting plates 12 are disposed on both sides of the fixed plate 11. A limiting groove 13 is formed between the limiting plates 12 and the fixed plate 11. A waist-shaped hole is provided on the limiting plate 12, and a bolt hole is provided on the base plate 8. A positioning bolt is disposed in the waist-shaped hole and connected to the bolt hole. Furthermore, the width of the limiting groove 13 can be adjusted according to the width of the rope. After the width of the limiting groove 13 is adjusted, the positioning bolt can be placed in the waist-shaped hole and the corresponding bolt hole to prevent the limiting plate 12 from moving relative to the fixed plate 11, thereby ensuring that the limiting groove 13 can stably maintain the set width.

[0030] The working principle of this utility model is as follows: First, one end of each of the two ropes to be knotted can be vertically placed in the two fixed slots 61 of the clamp 6. Then, the first rotary motor 5 will rotate, thereby driving the clamp 6 to rotate, so that one end of each rope to be knotted can rotate around the clamp 6 and a part of the rope overlaps. Then, the second cylinder 4 extends along the second direction, so that the clamp 6 can drive the rope to move into the limiting slot 13. Then, the cylinder and the first cylinder 3 work simultaneously. The first cylinder 3 retracts along the first direction, so that the rope is separated from the clamp 6. At the same time, the cylinder drives the pressure plate to move downward to press the rope tightly. The second rotary motor then drives the connecting seat 7 to rotate. The rotation of the connecting seat 7 will drive the pressure plate to rotate. The side wall of the pressure plate contacts the fixing plate 11 and the limiting plate 12. The rotation of the pressure plate will then drive the limiting plate 12 and the fixing plate 11 to rotate. The limiting plate 12 and the fixing plate drive the base plate 8 to rotate synchronously, thereby driving the rope to rotate, so that the sewing needle on the sewing machine 2 can sew the area where the rope overlaps.

[0031] 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.
