The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, an air blowing device includes an air blowing mold core 2 and a housing 1, in this embodiment, the air blowing mold core 2 is a horizontally arranged cylindrical structure, and a wire passing hole 21 for passing a wire 4 is arranged in the horizontal direction of the air blowing mold core 2. The horizontal direction of the shell 1 is provided with a through hole corresponding to the air-blowing mold core 2, the air-blowing mold core 2 is inserted into the through hole, the wall of the through hole of the shell 1 is provided with an annular air cavity 11, and the surface of the shell 1 is provided with an air inlet 13 communicated with the annular air cavity 11. When the wire 4 is air-blown to remove water, the air inlet 13 is externally connected with a high-pressure air source. The blowing mold core 2 is uniformly provided with a plurality of air outlet channels 22 in the circumferential direction for communicating the annular air cavity 11 with the wire passing holes 21, and a sealing and fixing structure is respectively arranged between the blowing mold core 2 and the shell 1 at the positions of two sides of the annular air cavity 11. In this embodiment, the sealing and fixing structure includes annular grooves respectively formed at two ends of the outer circumferential surface of the blowing mold core 2, and O-rings 3 arranged in the annular grooves in a matching manner, and the blowing mold core 2 and the housing 1 are sealed and fixed by the O-rings 3 after being assembled. The setting of O type circle 3 guarantees this air-blowing device leakproofness on the one hand, prevents that high-pressure gas from leaking, and on the other hand utilizes O type circle 3 and air-blowing mold core 2 and shell 1 between frictional force, and is fixed with air-blowing mold core 2 and shell 1. When the disassembly is carried out, the air-blowing mold core 2 and the shell 1 can be separated by pressing one end of the air-blowing mold core 2 to push outwards, so that the aim of quick disassembly is fulfilled.

In this embodiment, the air outlet channel 22 is disposed obliquely, and the outlet of the air outlet channel 22 is disposed toward the inlet end of the wire passing hole 21. The structure ensures that the moisture removed by blowing the wire 4 falls towards the wire inlet end of the wire through hole 21, namely the moisture falls towards the wire inlet end of the device, and ensures the water removal effect and quality of the wire 4.

In this embodiment, since the two ends of the wire 4 are shaken during the moving process, in order to prevent the wire 4 from being contacted and rubbed with the air blowing core, the wire passing hole 21 includes a wire inlet hole portion 211, a transition hole portion 212 and a wire outlet hole portion 213 sequentially arranged from the wire inlet end to the wire outlet end thereof, and the diameters of the wire inlet hole portion 211 and the wire outlet hole portion 213 are respectively larger than the diameter of the transition hole portion 212. A conical hole part 214 is arranged between the inlet hole part 211 and the transition hole part 212, and the outlet of the outlet channel 22 is arranged on the hole wall of the conical hole part 214. This structure further improves wire rod air-blowing water quality.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
