As shown in fig. 2-3, the filament winding mechanism 3 comprises a screw 31, a transmission rod 32, a filament winding nozzle 33 and an inner sleeve 34; one end of the screw 31 is fixedly connected with the transmission assembly 2, and when the driving device 1 rotates, the transmission assembly 2 is driven to rotate, and the transmission assembly 2 drives the screw 31 to coaxially rotate. The other end of the screw 31 is rotatably connected with the transmission rod 32, in addition, a thread section 311 is arranged on the outer peripheral side close to the end, and the thread section 311 is in threaded connection with the inner cavity of the inner sleeve 34; the inner sleeve 34 is hinged with the wire winding nozzle 33 relative to the other end of the screw 31, the hinged position can only rotate relatively, the transmission rod 32 is hinged with the wire winding nozzle 33 relative to the other end of the threaded rod, and the hinged position has a movable space. The outer side wall of the inner sleeve 34 is provided with a feeding and retreating positioning groove 341 and a rotating cam groove 342 which are communicated with each other, and the number of the feeding and retreating positioning groove 341 and the rotating cam groove 342 is two; two advance-retreat positioning grooves 341 are provided along the axial direction of the inner sleeve 34, and two rotation cam grooves 342 are provided along the circumferential direction of the inner sleeve 34. The locking assembly 4 comprises a limiting pin 41 and a first elastic piece 42 which drives the limiting pin 41 to be clamped on the inner sleeve 34, and the first elastic piece 42 is a spring; when the inner sleeve 34 moves forwards and backwards, the limiting pin 41 is in limiting fit with the advance and retreat positioning groove 341, so that the inner sleeve 34 cannot move in a rotating mode, and when the inner sleeve 34 moves in a rotating mode, the limiting pin 41 is in limiting fit with the rotating cam groove 342, so that the inner sleeve 34 cannot move in a straight line; a rotation stopping groove 343 is arranged between every two rotation cam grooves 342, and the rotation cam grooves 342 and the rotation stopping groove 343 are positioned in the same radial interval; the depths of the rotation cam groove 342 and the rotation stopping groove 343 become gradually shallower in the reverse direction of the rotation direction of the screw 31.
When in use, in the state that the inner sleeve 34 is not extended (the state is schematically shown in fig. 4), when the screw 31 rotates, the threaded section 311 of the threaded rod drives the inner sleeve 34 to move forward so as to extend the screw 31, and in the state that the inner sleeve 34 is not fully extended, the inner sleeve 34 can only move forward and backward and cannot rotate because the limiting pin 41 is clamped in the advance and retreat positioning groove 341; when the inner sleeve 34 moves forward to fully extend (see fig. 5 for a schematic state), the limiting pin 41 is clamped in the rotating cam groove 342, and the end of the threaded end of the screw 31 abuts against the inner cavity of the inner sleeve 34, so that the screw 31 can drive the inner sleeve 34 to rotate, the inner sleeve 34 can rotate, the limiting pin 41 can rotate relative to the rotating cam groove 342 and the rotation stopping groove 343, and finally the rotation of the wire winding nozzle 33 is realized, so that the steel wire is knotted. During the process of extending the inner sleeve 34 out of the screw 31, the filament winding nozzle 33 is matched with the hinging of the inner sleeve 34 and the transmission rod 32, so that the filament winding nozzle 33 is gradually closed, and when the inner sleeve 34 is completely extended out of the screw 31, the filament winding nozzle 33 is closed. When the screw 31 stops rotating, the inner sleeve 34 moves in the same direction under the action of inertia, and moves to the limit position and moves reversely under the action of the steel wire, and under the action of the rotation stopping groove 343, the limiting pin 41 can be clamped in the rotation stopping groove 343, so that the reverse rotation angle of the inner sleeve 34 is smaller than 180 degrees, and finally the looseness of the steel wire caused by the reverse movement of the inner sleeve 34 is reduced.
In the inner housing 34 having the above-described structure, as a preferred embodiment, there are two rotation stopping grooves 343, and the center line of the two rotation stopping grooves 343 intersects with the center line of the two rotation stopping grooves 343, and as a preferred embodiment, the center line of the two rotation stopping grooves 342 is perpendicular to the center line of the two rotation stopping grooves 343. I.e., the rotation cam groove 342 and the rotation stopping groove 343 are disposed at a 90 interval. By providing two rotation cam grooves 342 and a rotation stopping groove 343, the inner sleeve 34 can only be reversed by 90 ° at most when the reverse rotation occurs, which effectively reduces the unscrewing of the screwed wire. In addition, it should be noted that the provision of two rotation cam grooves 342 and rotation stopping grooves 343 on the inner sleeve 34 of the actual size also ensures the stability of the overall structure of the inner sleeve 34 and the stability of the fit of the inner sleeve 34 with the stopper pin 41. It should be noted that the advance and retreat positioning groove 341, the rotation cam groove 342, and the rotation stopping groove 343 may be provided in plural, which can reduce the angle at which the inner sleeve 34 is reversed, reducing the unscrewed wire.
As shown in fig. 2, the rotation stop groove 343 is provided with a guide section 3431 on the side close to the advance and retreat positioning groove 341, and the guide section 3431 is inclined toward the side close to the advance and retreat positioning groove 341. Specifically, the guiding section 3431 is arc-shaped, so when the limiting pin 41 is clamped in the rotation stopping groove 343 to stop the rotation of the inner sleeve 34, and the screw 31 drives the inner sleeve 34 to perform the reset motion (the inner sleeve 34 moves backwards), the limiting pin 41 can move out of the rotation stopping groove 343 along the guiding section 3431 and then is clamped in the advance and retreat positioning groove 341, and finally, the wire winding mechanism 3 can perform the next wire winding. During the resetting movement of the inner sleeve 34, the filament winding nozzle 33 is hinged and matched with the inner sleeve 34 and the transmission rod 32, so that the filament winding nozzle 33 is gradually opened, and when the inner sleeve 34 moves backwards to the initial position, the filament winding nozzle 33 is opened. As an improvement, the axial length of the rotation stopping groove 343 is longer than that of the rotation cam groove, which allows the stopper pin 41 to have more space for movement in the rotation stopping groove 343, thereby ensuring that the stopper pin 41 can perform a reset motion stably.
As shown in fig. 1-2, two symmetrically arranged protrusions 344 are provided in the inner cavity of the inner sleeve 34, and the protrusions 344 cooperate with the threaded section 311 of the screw 31. When the screw 31 rotates, the two screw blocks can move back and forth relative to the screw section 311, thereby driving the inner sleeve 34 to move back and forth. In addition, by arranging the two symmetrically arranged protruding blocks 344, the inner sleeve 34 is prevented from shaking in the moving process, and the moving stability of the inner sleeve 34 is improved. As a further improvement, a second elastic element 5 is arranged between the driving device 1 and the screw 31, and the second elastic element 5 is a spring, so that the screw 31 is more stable in the torque transmission process.
