Referring to fig. 1, the reciprocating driving mechanism drives the traction seat 2 and the limit post 4 to perform horizontal reciprocating motion synchronously, so that the traction seat 2 and the limit post 4 pull the yarn through the guiding mechanism 6 to be uniformly wound on the winding device, and meanwhile, the traction seat 2 drives the tension adjusting mechanism 7 to perform synchronous motion, and the tension adjusting mechanism 7 gradually reduces the tension of the yarn in the process of moving from two ends of the winding device to the middle, so as to realize protection of the yarn.
It should be noted that, in this embodiment, the guiding mechanism 6 on the fixing post 3 is used to fix the horizontal position of one end of the yarn, and the guiding mechanisms 6 on the traction seat 2 and the limit post 4 are used to make the yarn always keep the vertical state with the winding roller 15, the connecting arm 5 is used to connect the traction seat 2 with the fixing post 3, and since the length of the connecting arm 5 cannot be changed, the connecting arm 5 actually performs the reciprocating swing around the fixing post 3 as the center of the circle to adapt to the reciprocating horizontal movement of the traction seat 2, when the connecting arm 5 and the traction seat 2 form a straight line, that is, the traction seat 2 moves to the middle position of the winding roller 15, at this time, the yarn does not contact with any guiding mechanism 6, the yarn tension is at this time minimum, and when the traction seat 2 moves to any one end of the winding roller 15, the yarn tension reaches at this time maximum, so that when the traction seat 2 moves from one end of the winding roller 15 to the other end, the yarn tension change gradually decreases and then gradually increases, and in the static state, the yarn tension is at the maximum (that is just when the traction seat 2 reaches one end of the winding roller 15 in the static state).

Referring to fig. 2, 5, 6 and 7, when the traction seat 2 can drive the limit post 4 to reciprocate horizontally under the guidance of the limit structure in the process of reciprocating horizontal movement, the limit structure comprises a guide groove 8, a sliding groove 9 and a connecting rod 10, the guide groove 8 is arranged on the surface of the machine body 1, the bottom end of the limit post 4 is slidably connected in the guide groove 8, the sliding groove 9 is arranged on the surface of the traction seat 2, the limit post 4 is slidably connected in the sliding groove 9, the connecting rod 10 is fixedly connected to the inner wall of the sliding groove 9, the limit post 4 is slidably connected on the surface of the connecting rod 10, the projection of the guide groove 8 on the horizontal plane is an arc, the circle center of the arc of the guide groove 8 coincides with the circle center of the fixed post 3, the length of the connecting arm 5 is the same as the radius of the arc of the guide groove 8, the bottom of the limit post 4 can be driven to move in the guide groove 8 in the process of reciprocating horizontal movement of the traction seat 2, since the guide groove 8 has a horizontal length in the axial direction of the reciprocating screw 12, the traction seat 2 can drive the limit post 4 to move in the sliding groove 8 during reciprocating motion, and the moving direction is mutually perpendicular to the moving direction of the traction seat 2, so that the limit post 4 can drive the rack 20 to synchronously reciprocate horizontally, the rack 20 is always meshed with the gear 19, so that the threaded rod 72 can be driven by the gear 19 to reciprocate, the wire seat 74 can reciprocate horizontally on the surface of the guide rod 73, the limit post 4 can move in the guide groove 8 under the driving of the connecting arm 5, the limit post 4 can synchronously move in the sliding groove 9 at the moment, but the traction seat 2 always reciprocates horizontally, for the limit post 4, when the limit post 4 moves to the middle point of the guide groove 8, the limiting post 4 just moves from one end to the other end in the chute 9, the gear 19 can be driven to rotate for the rack 20, when the limiting post 4 moves from the middle point of the guide groove 8 to the other end, the limiting post 4 can reset in the chute 9 and drive the rack 20 to move reversely, so that the gear 19 rotates reversely, at the moment, the gear can drive the threaded rod 72 to rotate reciprocally, thereby driving the guide seat 74 to move reciprocally and horizontally under the limit of the guide rod 73, when the traction seat 2 moves to the middle point of the winding roller 15, the wire seat 74 moves from one end of the threaded rod 72 to the middle point of the threaded rod 72 and contacts with the limiting sleeve 23, at the moment, the distance between the limiting post 4 and the partition 71 is nearest, as the traction seat 2 moves continuously, the limiting post 4 moves towards the direction away from the partition 71, the rack 20 drives the gear 19 to turn over, and the threaded rod 72 drives the wire seat 74 to reset.
The traction seat 2 is located at one end of the winding roller 15, the guiding mechanism 6 on the limit post 4 and the guiding mechanism 6 on the traction seat 2 fix the yarn above the traction seat 2 in a state parallel to the partition 71, but because the wire seat 74 is located at one side of the partition 71 far from the winding roller 15, the bottom of the yarn can be horizontally offset while vertically offset, so that the yarn is clamped in the wire groove 18, and because the yarn is tensioned after being conducted by the three guiding mechanisms 6, the wire seat 74 can further tension the yarn by the method for offsetting the yarn, so as to increase the tension of the yarn, and therefore, in practical use, the tension of the yarn can be adjusted to the maximum degree by the existing device or technology, so that when the traction seat 2 and the limit post 4 uniformly wind the yarn on the winding roller 15 through the guiding mechanism 6, the tension of the yarn is changed, and the change is uniform.
It should be noted that, assuming that two ends of the winding roller 15 are A, B two points, the middle point of the winding roller 15 is C point, when the traction seat 2 drives the yarn to move from a to B or from B to a, the yarn will necessarily pass through C point, the wire seat 74 is located at one end of the threaded rod 72 at a point a or B, the tension of the yarn will be maximum, the wire seat 74 is located at the middle point of the threaded rod 72 at C point, the yarn will be minimum, the yarn tension will gradually decrease from a point a or B to C point, that is, the time is shorter when the yarn is at the maximum tension, so that the yarn can be prevented from breaking by the tension of the yarn dynamic change.
It should be appreciated that in this embodiment a grooved wheel may be added to the bottom of the wire seat 74 to allow the yarn to move in the grooves to convert sliding friction with the wire grooves 18 into rolling friction, thereby protecting the yarn.
Referring to fig. 1 and 4, the guide slot 8 is arc-shaped, the end of the limiting post 4 can be always located in the guide slot 8 when the traction seat 2 moves, so that the limiting post 4 can reciprocate horizontally in the sliding slot 9, and the limiting post 4 can not rotate circumferentially in the moving process due to the limitation of the connecting rod 10, so that the guide mechanism 6 on the limiting post 4 is always kept in a horizontal state with the guide mechanism 6 on the traction seat 2 and the guide mechanism 6 on the fixing post 3.
Specifically, the guiding mechanism 6 includes a base 61, a rotating shaft 62, a first guide wheel 63 and a second guide wheel 64, the three bases 61 are respectively and fixedly installed at the tops of the fixed column 3, the limit column 4 and the traction seat 2, the two rotating shafts 62 are symmetrically and rotatably connected at the tops of the bases 61, the first guide wheel 63 is fixedly installed on the surface of one rotating shaft 62, the second guide wheel 64 is fixedly installed on the surface of the other rotating shaft 62, the bottom of the first guide wheel 63 is provided with an annular concave portion 21, the bottom of the second guide wheel 64 is provided with an annular convex portion 22, the width of the annular convex portion 22 is exactly the same as that of the annular concave portion 21, and the annular convex portion 22 is abutted against the inner wall of the annular concave portion 21.
Referring to fig. 3, in this embodiment, the first guide wheel 63 and the second guide wheel 64 are used to pull the yarn, so that the yarn can be uniformly wound on the surface of the winding roller 15, where the first guide wheel 63 and the second guide wheel 64 can rotate through the rotating shaft 62, so that sliding friction between the yarn and the wire ring in the prior art can be converted into rolling friction, thereby protecting the yarn, and the gap between the first guide wheel 63 and the second guide wheel 64 is smaller, when the traction seat 2 is located at the point a or the point B, the first guide wheel 63 or the second guide wheel 64 can be used to quickly pull the yarn to return, so as to prevent excessive yarn from winding at two ends of the winding roller 15, and in the above process, when the traction seat 2 moves from the point a to the point C, the two first guide wheels 63 can be used to simultaneously pull the yarn, and when the traction seat 2 moves from the point B to the point C, the two second guide wheels 64 can be used to simultaneously pull the yarn, and finally, when the traction seat 2 is located at the point B, the two guide mechanisms 6 on the traction seat 2 can be used to contact more yarn, and the yarn can be protected.
It should be noted that, the annular protruding portion 22 can shield the yarn from the bottom, so that the yarn only falls on the surface of the annular protruding portion 22, and does not enter the gap between the first guide wheel 63 or the second guide wheel 64 and the base 61 even if the yarn falls below the first guide wheel 63 or the second guide wheel 64.
