[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention;

[0028] like Figure 1-10 ,

[0029] A rotary knotting device comprises a machine base 1 and a knotting part 4, wherein the knotting part 4 comprises a knotting driver 41, a knotting mounting seat 42, a knotting guide block 43, an upper thread pressing nozzle 44, a rotating shaft 45, a lower thread pressing nozzle 46 and a guide wheel 47, and the knotting mounting seat 42 is fixedly arranged on the machine base 1, such as Figure 1 and Figure 5, X+ direction is the right side, X- direction is the left side, Y+ direction is the front side, Y- direction is the rear side, the knotting guide block 43 is fixedly arranged above the knotting mounting seat 42, the lower end of the rotating shaft 45 vertically passes through the knotting guide block 43 and the knotting mounting seat 42 and extends to the bottom of the knotting mounting seat 42, the knotting driver 41 drives the rotating shaft 45 to rotate relative to the knotting mounting seat 42 and the knotting guide block 43, that is, when the knotting driver 41 drives the rotating shaft 45 to rotate, the knotting mounting seat 42 and the knotting guide block 43 do not rotate with the rotating shaft 45 rotates, the upper crimping nozzle 44 is in the shape of a "7", the lower end of the upper crimping nozzle 44 is arranged at the upper end of the rotating shaft 45 and rotates synchronously with the rotating shaft 45, the middle part of the upper crimping nozzle 44 is provided with an axle pin 48, the upper end part of the upper crimping nozzle 44 is provided with a groove 441, the lower end of the lower crimping nozzle 46 is provided with a guide wheel 47, the upper end of the lower crimping nozzle 46 is provided with a pressure head 461 protruding upward, the axle pin 48 passes through the middle part of the upper crimping nozzle 44 and the middle part of the lower crimping nozzle 46, and the axle pin 48 divides the lower crimping nozzle 46 into an upper crimping nozzle 46 and a lower crimping nozzle 46. The weight of the lower part of the lower thread pressing nozzle 46 (including the guide wheel 47) is greater than the weight of the upper part of the lower thread pressing nozzle 46. The lower thread pressing nozzle 46 rotates along the shaft pin 48 relative to the upper thread pressing nozzle 44 in a shear-like manner. Under the action of gravity, the upper part of the lower thread pressing nozzle 46 rotates upward, and the pressure head 461 is correspondingly located in the groove 441. The upper end surface of the knotting guide block 43 is a guide surface of unequal heights. At least one guide high point 431 is provided on the guide surface. When the rotating shaft 45 rotates, it will drive the upper thread pressing nozzle 44 and The lower wire pressing nozzle 46 rotates synchronously, and during the synchronous rotation, the guide wheel 47 moves along the guide surface, and when the guide wheel 47 contacts the high point 431, the high point 431 will lift the guide wheel 47 and the lower part of the lower wire pressing nozzle 46, and at the same time, the lower wire pressing nozzle 46 rotates downward relative to the upper wire pressing nozzle 44 to form an open state. Similarly, when the guide wheel 47 contacts the low point, the guide wheel 47 and the lower part of the lower wire pressing nozzle 46 rotate downward under the action of gravity, and the upper part of the lower wire pressing nozzle 46 rotates upward relative to the upper wire pressing nozzle 44 to form a closed state.

[0030] like Figure 8-10 , the working principle of the knotting part 4 is as follows:

[0031] like Figure 8 , is the state at the beginning of knotting, the angle is set to 0 degrees, the cord 5 is set in the Y direction, the upper thread pressing nozzle 44 and the lower thread pressing nozzle 46 are closed and in the X direction, and the thread end of the cord 5 faces the Y-direction, the cord 5 passes under the lower thread pressing nozzle 46, and the two ends of the cord 5 are higher than the upper thread pressing nozzle 44, and then the knot is tied counterclockwise;

[0032] like Fig. 9, is the state of rotating counterclockwise to 300 degrees, at this time, the guide wheel 47 contacts the high point 431, and the lower wire pressing nozzle 46 forms an open state relative to the upper wire pressing nozzle 44, and the winding path from the wire rope 5 to the wire end is: below the lower wire pressing nozzle 46 - right side (the covered side) - above the upper wire pressing nozzle 44 - left side of the upper wire pressing nozzle 44 - then bypass the wire rope 5 (that is, tighten the wire rope 5 in the Y+ direction) - finally pass through between the upper wire pressing nozzle 44 and the lower wire pressing nozzle 46 to the Y- direction (for ease of understanding, the following explanation is added: at this time, if the upper wire pressing nozzle 44 and the lower wire pressing nozzle 46 are still in the closed state, the winding path from the wire rope 5 to the wire end is: below the lower wire pressing nozzle 46 - right side (the covered side) - above the upper wire pressing nozzle 44 - left side - below the lower wire pressing nozzle 46 to the Y- direction, forming a state of winding around the upper wire pressing nozzle 44 and the lower wire pressing nozzle 46 for one circle);

[0033] like Fig.10 , is a state of rotating 330-360 degrees counterclockwise. When the guide wheel 47 passes the high point 431, it will quickly reach the lowest point, forming a closed state of the lower wire pressing nozzle 46 and the upper wire pressing nozzle 44, and the wire rope 5 located between the upper wire pressing nozzle 44 and the lower wire pressing nozzle 46 is clamped between the groove 441 and the pressure head 461. Since the lower wire pressing nozzle 46 and the upper wire pressing nozzle 44 are in a conical bird's beak shape when in the closed state, the wire rope 5 wrapped under the lower wire pressing nozzle 46 and above the upper wire pressing nozzle 44 will fall off, while the wire rope 5 in the groove 441 will not fall off, thereby completing the knotting. Since the force clamping the wire rope 5 is gravity, it is easy to take out the wire rope 5 after the knotting is completed.

[0034] According to a further technical solution, the guide wheel 47 is rotated to set the lower end of the lower thread pressing nozzle 46.

[0035] According to a further technical solution, when the pressing head 461 is correspondingly located in the groove 441 , the pressing head 461 protrudes upward from the upper end of the groove 441 .

[0036] As a further technical solution, the knotting guide block 43 is sleeved on the upper end of the rotating shaft 45 and fixedly arranged above the knotting mounting seat 42 .

The clamp 22 is a two symmetrical structure. The finger cylinder 21 drives the clamp 22 to perform an opening or closing action when it moves relative to each other. The closed state is the state of clamping the rope 5. When the clamp 22 is closed, a wire hole 23 through which the rope 5 passes is formed between the two clamps 22. The wire hole 23 faces the knotting part 4. The machine base 1 is also provided with a driving cylinder (not shown in the figure) that can drive the finger cylinder 21 to reciprocate along the X direction. The rope taking part 3 is provided with a reciprocating motion along the Y direction and across the knotting part 4.

The number of the rope taking heads 34 is the same as the number of the rope threading part 2. When the rope taking head 34 is located at the front side, the driving cylinder drives the rope threading part 2 to clamp the rope 5 and move along the X direction, and the rope 5 is sent to the rope taking head 34, the rope taking head 34 clamps the rope 5, and then the finger cylinder 21 opens, and the rope taking head 34 passes the knotting part 4 and moves to the rear side, and then the upper thread pressing nozzle 44 and the lower thread pressing nozzle 46 rotate synchronously counterclockwise to tie a knot.

[0038] Further technical solutions, such as Figure 6-7 The rope-taking head 34 includes a rope-taking drum 341, a rope-taking block 342 and a pressing shaft 348. An open rope-taking hole 344 is formed on one side of the rope-taking drum 341. The rope-taking drum 341 is arranged along the X direction. The rope-taking hole 344 faces the line hole 23. Two notches 345 are symmetrically arranged on both sides of the outer circumference of the rope-taking drum 341. The two notches 345 are symmetrically arranged at 180 degrees. The rope-taking block 342 is symmetrically arranged in the two notches 345. A rotating shaft is provided on the rope-taking block 342. An axial hole for inserting the rotating shaft is provided on the rope-taking drum 341. A torsion spring 3421 is sleeved on the rotating shaft. One end of the torsion spring 3421 is pressed against the inner side of the rope-taking head 34 (i.e., located on the axis side of the rope-taking drum 341), and the other end is pressed against the outside of the rope-taking drum 341. Figure 7As shown, under the action of the torsion spring 3421, the rope taking block 342 generates a force to open to both sides, which is convenient for the rope taking block 342 to reset after the clamping is completed. A pressing head 343 is formed on the left side (X-direction) of the rope taking block 342, and a pressing portion 346 protruding toward the axial direction of the rope taking drum 341 is provided on the right side of the rope taking block 342. A protrusion 349 is provided on the left side of the pressing shaft 348, and a through hole 3411 is provided on the right side of the rope taking drum 341. The right side of the pressing shaft 348 is correspondingly inserted into the through hole 3411 and Extending to the outside, on the other side of the rope-taking drum 341, when the rope threading part 2 delivers the end of the wire rope 5, the cylinder (not shown in the figure) is used to drive the pressing shaft 348 to move to the right, and the protrusion 349 presses on the two pressing parts 346, so that the two pressing heads 343 rotate along the rotating axis toward the axis of the rope-taking drum 341 to form a pressing action, thereby pressing the end of the wire rope 5. When the clamping action is completed and needs to be reset, the cylinder drives the pressing shaft 348 to move to the left, and the rope-taking block 342 is reset under the action of the torsion spring 3421.

[0039] As a further technical solution, rope taking teeth 347 are provided on the inner sides of the two pressing heads 343 .

When the clamp 22 is closed, the two clamping nozzles 24 form a cylindrical structure. The outer diameter of the clamping nozzle 24 is smaller than the inner diameter of the rope taking hole 344, which facilitates the insertion of the clamping nozzle 24 into the rope taking hole 344, and can better transfer the thread end of the rope 5 to the rope taking head 34.

[0041] As a further technical solution, the clamping nozzle 24 is provided with a notch 25 corresponding to the notch 2 345 . When the clamping nozzle 24 is inserted into the rope taking hole 344 , the rope taking block 342 passes through the notch 2 345 through the notch 25 to clamp the rope 5 in the wire hole 23 .
