Referring to fig. 1-4, in this embodiment, a novel lower suction nozzle of a winder includes:

the suction head mechanism 1 comprises a suction nozzle body 11, a connecting component 12 is arranged on the suction nozzle body 11, the suction nozzle body 11 comprises a lead part 111 for introducing a sliver, a flaring part 112 is arranged on the corresponding side of a lead port of the lead part 111, a connecting part 113 connected through the flaring part 112 is arranged on the coaxial line of the lead part 111, and the connecting component 12 is arranged on the connecting part 113.

Under the condition that a suction nozzle is blocked by adopting a flat elliptic port in the prior art, the suction nozzle mechanism 1 in the embodiment adopts a circular lead part 111, so that compatibility and adaptability of accidental loopers are greatly enhanced, even if larger yarn groups are sucked normally, the connecting part 113 is communicated with the lead part 111 by matching with the expanding part 112, so that the airflow velocity of the suction port of the lead part 111 is more rapid, the yarn groups can be sucked due to deformation caused by strong airflow even if the diameter of the suction port of the yarn groups is slightly larger than that of the lead part 111, the effect that the yarn groups pass through the lower suction nozzle smoothly is eliminated, and the bobbin yarn breakage caused by blocking of the lower suction nozzle has on the operation of a winder is avoided.

Because the flaring portion 112 is in a truncated cone shape, the narrow end corresponding to the size of the lead portion 111 is connected to the lead portion 111, and the wide end of the other end is connected to the connecting portion 113, so that the size from the lead portion 111 to the connecting portion 113 is increased, the negative pressure suction force in the lead portion 111 is increased, and the agglomerated strings can be sucked.

Referring to fig. 1-4, the connecting assembly 12 includes a sealing head portion 121 disposed on the connecting portion 113 and a fixing portion 122 disposed on an end of the sealing head portion 121 away from the connecting portion 113, a sealing cavity 2 is disposed between the sealing head portion 121 and the connecting portion 113, and a connecting tube 3 having one end located in the sealing cavity is disposed outside the connecting portion 113.

In the prior art, the suction nozzle is inserted into the negative pressure rubber tube, the suction nozzle is connected with the negative pressure rubber tube in an interference fit manner, and meanwhile, the air leakage can be reduced in an inserting manner, but the rubber tube is easy to break, so that the air leakage is serious, and the suction nozzle can be led to normally suck yarn strips, so that the connecting pipe 3 can be directly inserted into the connecting pipe 3 at the connecting part 113, and the connecting pipe 3 can enter the sealing cavity 2 along with going deep into the connecting pipe 3, and is clamped between the connecting part 113 and the sealing head part 121, so that the connecting pipe 3 is extruded from outside to inside to realize sealing connection with the connecting part 113, and the breakage of the connecting pipe 3 is avoided.

Based on the fact that the outer diameter of the connecting portion 113 is equal to the inner diameter of the connecting tube 3, the tube wall thickness of the connecting tube 3 is larger than the width of the sealing cavity 2, and the connecting tube 3 is in interference fit with the end socket portion 121 through extruding the connecting tube 3 into the sealing cavity 2, so that detachable connection is achieved.

Referring to fig. 1-4, the fixing portion 122 includes a connecting ring 1221 disposed on the header portion 121 and a pipe clamp 1222 disposed on the connecting ring 1221, where a tightening hole 4 is formed in the connecting ring 1221, the pipe clamp 1222 is composed of a binding ring and a fastening piece, the binding ring is disposed on the connecting ring 1221, the head and the tail of the binding ring are flush with the tightening hole 4, the fastening piece is disposed between the head and the tail of the binding ring, and the fastening piece corresponds to the tightening hole 4.

After the connection between the connection pipe 3 and the connection portion 113 is completed, the pipe clamp 1222 of the fixing portion 122 is tightened, so that the pipe clamp 1222 is deformed and tightened with the connection ring 1221, the connection between the connection portion 113 and the connection pipe 3 is reinforced, and the connection stability between the connection portion 113 and the connection pipe 3 is improved.

In this embodiment, the connecting ring 1221 is used as a connecting transition piece between the pipe clamp 1222 and the head 121, and tightening holes 4 corresponding to the intervals between the ends of the pipe clamp 1222 are formed in the connecting ring 1221, so that when the pipe clamp 1222 is screwed, the connecting ring 1221 is more easily matched with the deformation of the pipe clamp 1222 to fix the connecting pipe 3, and the connecting portion 113 and the connecting pipe 3 are connected and reinforced.

Based on the above, the outer diameter of the connecting ring 1221 serving as a transition piece is smaller than the outer diameters of the pipe clamp 1222 and the head 121, so that the pipe clamp 1222 is tightened at the tightening hole 4 end to end, thereby fixing the connecting pipe 3 with the connecting ring 1221.

Further, an end surface of the pipe clamp 1222 remote from the connection ring 1221 is flush with an end surface of the connection portion 113 passing through the connection portion 113, and a connection pipe is located between the connection ring 1221 and the pipe clamp 1222 and the connection portion 113.

When the pipe clamp 1222 and the connection ring 1221 fix the connection pipe 3, the connection pipe 3 is pressed outside the connection part 113, so that the length of the connection part 113 passing through the head part 121 is equal to the sum of the widths of the head part 121, the connection ring 1221 and the pipe clamp 1222, and the end surface thereof is flush with the end surface of the pipe clamp 1222, thus pressing the connection pipe 3 on the connection part 113 inwardly of the pipe clamp 1222.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
