A fixed sleeve 42 is arranged at the end of the reciprocating shaft 12 away from the lifting mechanism 20, and a lifting motor 43 is arranged at the end of the fixed sleeve 42 away from the reciprocating shaft 12, and the output shaft of the lifting motor 43 is connected with the transmission shaft 41 through a shaft coupling, that is, the shell part of the lifting motor 43 is fixed with the reciprocating shaft 12, and after the lifting motor 43 is started, the output shaft thereof drives the transmission shaft 41 to rotate through the shaft coupling. The transmission shaft 41 extends out of the reciprocating shaft 12 at the end close to the lifting mechanism 20 and is provided with a driving wheel 44 at the end, and the square tube 21 is vertically provided with a strip-shaped hole 27 at the side close to the reciprocating shaft 12, and guide wheels 45 are rotatably arranged at both ends of the strip-shaped hole 27, the synchronous belt 24 is wound around the driving wheel 44 from the strip-shaped hole 27, and the flanges of the two guide wheels 45 are in contact with the outer belt surface of the synchronous belt 24. In this way, when the lifting motor 43 drives the transmission shaft 41 to rotate, the driving wheel 44 is driven to rotate, which can drive the synchronous belt 24 to move, and the synchronous belt 24 can be stopped and started at any time, so as to achieve the purpose of accurate control.

[0035] The beam splitting mechanism 30 comprises a fixed plate 31 arranged at the side of the I-shaped seat 26 away from the reciprocating shaft 12, and a plurality of beam splitting assemblies 32 are arranged on the fixed plate 31, which are used for forcibly splitting the yarn. Specifically, the fixed plate 31 is arranged vertically along the length direction of the reciprocating shaft 12, and the middle part is connected with the I-shaped seat 26, so that the fixed plate 31 is arranged on both sides of the direction tube. A fixed seat 33 is arranged on the side of the fixed plate 31 away from the I-shaped seat 26 and located on both sides of the square tube 21, and a sliding groove 34 is arranged from the fixed seat 33 to the end of the fixed plate 31, and two sliding seats 35 are slidably arranged in the sliding groove 34. The fixed seat 33 and the sliding seat 35 are both provided with the beam splitting assembly 32, that is, six beam splitting assemblies 32 are arranged on the fixed plate 31, two of which are fixed, and four of which are movable, and the sliding seat 35 and the beam splitting assembly 32 can be additionally arranged according to actual needs.

[0036] The first connecting plate 37 is provided on the sliding seat 35, and the first through hole 371 and the second through hole 372 are arranged on the first connecting plate 37 in an up-down interval. The second connecting plate 38 is provided on the fixed seat 33, and the third through hole 381 is arranged on the second connecting plate 38 and is coaxial with the second through hole 372. The first pull rod 373 is arranged on the outer first connecting plate 37 and extends towards the fixed seat 33. One end of the first pull rod 373 is fixed in the corresponding first through hole 371, and the other end of the first pull rod 373 passes through the first through hole 371 on the inner first connecting plate 37 and is provided with the first nut 374 at the end, and the outer diameter of the first nut 374 is larger than the hole diameter of the first through hole 371.

In this way, when the outer sliding seat 35 slides outward, the first pull rod 373 will move outward. When the first nut 374 moves close to the first through hole 371 on the inner first connecting plate 37, the inner sliding seat 35 will move outward together with the first nut 374. The second pull rod 375 will also move together with the first connecting plate 37 on the inner sliding seat 35. When the second nut 376 moves close to the third through hole 381 on the second connecting plate 38, the second connecting plate 38 cannot move because it is arranged on the fixed seat 33, so that the two sliding seats 35 slide to the maximum position.

[0037] The buffer column 39 is further arranged on the inner side of each sliding seat 35. When it is necessary to fold the beam splitting assembly 32, the outer sliding seat 35 slides inward, and the first pull rod 373 will move inward and pass through the first through hole 371 on the inner first connecting plate 37. When the buffer column 39 on the outer sliding seat 35 contacts the inner sliding seat 35, the inner sliding seat 35 will move inward together with the buffer column 39. The second pull rod 375 will also pass through the third through hole 381 on the second connecting plate 38, and the buffer column 39 on the inner sliding seat 35 will contact the fixed seat 33, so that the inner sliding seat 35 cannot continue to move inward. The buffer column 39 avoids mutual collision between the sliding seat 35 and the fixed seat 33 when folding, and also keeps a certain distance between the fixed seat 33 and the sliding seat 35, so that the beam splitting assembly 32 cannot be completely folded together and the yarns cannot be entangled with each other.

[0038] Further, two sliding mechanisms 36 are arranged on the fixed plate 31 to drive the two sliding seats 35 to slide in the sliding grooves 34 respectively. The sliding mechanism 36 comprises a sliding cylinder 361 arranged on the fixed plate 31, and the telescopic rod of the sliding cylinder 361 is arranged outside the cylinder body and the end of the telescopic rod is connected with the sliding seat 35 outside through a connecting block 362. In this way, the movement of the sliding seat 35 outside can be driven by the sliding cylinder 361, and the two sliding seats 35 can be driven to move successively, so that the three groups of beam splitting assemblies 32 on the same side can be separated and folded.

[0039] The beam splitting assembly 32 comprises a clamping block 321 arranged on the fixed seat 33 or the sliding seat 35, and two carbon rods 322 are arranged in the clamping block 321 in a spaced manner, and the length direction of the carbon rods 322 is perpendicular to the plate surface of the fixed plate 31. When the yarn is arranged between the two carbon rods 322, the friction between the yarn and the carbon rods 322 can be effectively reduced, and the yarn can be protected.
