Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

It should be noted that, in the description of the technical solutions of the present invention, some directional words, such as "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", etc., used for clearly describing the technical features of the present invention are all in terms of the orientation of the drawings of the present invention.

Examples

As shown in fig. 1 and fig. 2, the optical cable drying apparatus of the embodiment includes a water absorption device 1 and a drying cylinder 2, the water absorption device 1 and the drying cylinder 2 are sequentially installed on an apparatus main body 3 at intervals along the advancing direction of the optical cable, that is, the optical cable is firstly dewatered by the water absorption device 1, and then air-dried by the drying cylinder 2, so as to achieve the purpose of thoroughly removing the residual moisture on the surface. For improving dewatering efficiency, the both sides of optical cable all are equipped with water absorption device 1, and water absorption device 1 includes that the outside encloses hollow tube 11 and the spacing boss 4 of fixed mounting on equipment main part 3 that is equipped with cotton 12 that absorbs water, and cotton 12 that absorbs water links firmly in the periphery of hollow tube 11, and cotton 12 that absorbs water adopts polyester fiber cotton or sponge, has good water absorption performance, can be fast with it the surperficial moisture absorption of optical cable of contact dry. The hollow tube 11 is inserted outside the limit boss 4, and the absorbent cotton 12 outside the hollow tube 11 is in contact with the optical cable.

Specifically, as shown in fig. 3, the limiting boss 4 includes a fixing member 42 and an annular rotating member 43 sleeved outside the fixing member 42, the fixing member 42 is fixed to the apparatus main body 3, and more specifically, the fixing member 42 is welded to the apparatus main body 3. The rotating member 43 is rotatably connected with the fixing member 42 through a bearing, at least two slots 41 are circumferentially arranged on the outer side of the rotating member 43 at intervals, in this embodiment, three slots 41 are provided, corresponding inserting pieces 13 are fittingly arranged on the inner side wall of the hollow tube 11, the inserting pieces 13 are inserted into the slots 41, thereby realizing the insertion and fixation of the hollow tube 11 and the rotating piece 43, and because the rotating piece 43 can rotate, when the optical cable is brought into contact with the absorbent cotton 12 outside the hollow tube 11 and rapidly moved, the frictional force transmitted to the absorbent cotton 12 can be converted into a rotational force to rotate the hollow tube 11 and the rotational member 43 relative to the fixed member 42, thereby greatly reducing the friction force between the absorbent cotton 12 and the surface of the optical cable, avoiding the temperature rise of the optical cable caused by friction heating to further influence the performance of the optical cable, meanwhile, the water absorption cotton 12 rotates to absorb water by using different parts, and compared with the water absorption at the same part for fixing the position, the water absorption efficiency is greatly improved.

As shown in fig. 4, 5 and 6, in the present embodiment, the drying cylinder 2 has a channel at a central portion through which the optical cable can pass, an air duct 24 is disposed between the inner side wall and the outer side wall of the drying cylinder 2, one end of the air duct 24 is communicated with a blower, and the blower is a high pressure blower and provides high pressure air for the air duct 24. The air duct 24 includes two independent spiral air ducts arranged in parallel, one end of each spiral air duct is communicated with the air inlet pipe 22, and the two air inlet pipes 22 are communicated with the blower.
