At present, a gas hose is mostly used to connect compressed air to blow dry the cable. According to the number of connected hoses, it is divided into a single-stage water blowing device or a double-stage water blowing device. The defects are: this water blowing device only has one accommodating cavity for accommodating the cable, so only one cable can be blown in one operation, and the efficiency is low; at the same time, there are certain requirements for the line speed of the cable. If it is too fast, a more ideal water blowing effect cannot be achieved. Utility Model Content

[0009] Furthermore, the wire feeding guide wheel is provided with at least two wire grooves along its axial direction.

[0010] Furthermore, a sound-absorbing cotton ring is provided at the coaxial part of each group of the outlet ends.

[0011] The beneficial effects of the utility model are as follows:

[0012] Compared with the single-cable, double-stage water blowing device in the prior art, the utility model arranges two sets of parallel cable channels on the water blowing box, which can simultaneously perform water blowing treatment on two sets of extruded cables, thereby significantly improving work efficiency; in order to avoid the problem of unsatisfactory water blowing effect when the line speed is fast, axial air supply and central air supply are added on the basis of the existing double-stage air supply, thereby improving the water blowing effect.

DETAILED DESCRIPTION

[0019] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0020] The utility model provides a cable high-speed dual-channel water blowing device, aiming to solve the problems of low water blowing efficiency of a single cable in a traditional water blowing device and unsatisfactory water blowing effect of a dual air delivery hose at a high line speed.

[0021] like Figures 1 to 3As shown, the utility model includes an openable and closable water blowing box 1 body, two sets of parallel cable channels 2 are arranged inside the water blowing box 1 body, lateral air supply hoses 3 connected to the cable channels 2 are respectively installed on both sides of the water blowing box 1 body, and wire feeding guide wheels 4 are installed on the front and rear sides of the water blowing box 1 through brackets.

[0022] Through the above technical solution, the existing openable water blowing box 1 is designed with an enlarged size, that is, the width of the water blowing box 1 is increased without changing the axial length. As a result, two sets of independent cable channels 2 parallel to each other can be designed along the width direction, so that two sets of extruded cables that need water blowing can be installed, which significantly improves work efficiency.

[0023] In particular, on the basis of the present invention, the technical solutions of arranging 2 or more groups, that is, multiple groups of cable channels 2 along the width direction are all within the scope of the solutions of the present invention.

[0024] In some embodiments, each group of cable channels 2 has an inlet end 21 and an outlet end 22 , and each outlet end 22 is designed with a flared opening 23 , and the flared opening 23 is designed at an obtuse angle.

[0025] Through the above technical solution, the obtuse-angled flared opening 23 design can facilitate the gas supply from the axial blowing assembly 6 to flow into the cable channel 2, thereby accelerating the flow rate in the pipe.

[0026] In some embodiments, a third air delivery hose 5 is further provided at the center of the water blowing box 1 near the line inlet end 21 , and the third air delivery hose 5 is respectively connected to the two groups of cable channels 2 inside the water blowing box 1 .

[0027] Through the above technical solution, since two sets of cable channels 2 are designed, the cables in the original single cable channel 2 are blown with water in the circumferential direction through the double-section air hoses on both sides. Now after the optimization to double cable channels 2, each cable has only one side of the lateral air hose 3 for blowing water, and one and a half circles of airway blowing are missing along its circumference. Therefore, a set of third air hoses 5 is added to blow water to the cable channels 2 on both sides from the center at the same time, thereby improving the blowing effect.

[0028] In some embodiments, an axial blowing assembly 6 is also included, and the axial blowing assembly 6 includes an outer cooling ring 61 and an inner cooling ring 62 arranged along the inner wall of the wire feeding guide wheel 4, and the end faces of the outer cooling ring 61 and the inner cooling ring 62 are sealed by arranging sealing rings, and an air delivery cavity is formed between the outer cooling ring 61 and the inner cooling ring 62, and a fourth air delivery hose 63 connected to the air delivery cavity is also arranged on one side of the outer cooling ring 61 and the inner cooling ring 62, and a plurality of air holes 64 facing the cable channel 2 are arranged through the surface of the wire feeding guide wheel 4.

[0029] Through the above technical solution, the axial blowing assembly 6 can add a gas transmission path along the axial direction of the cable, so as to directly enter the cable channel 2 through the expansion 23, accelerate the flow rate in the pipe, and improve the water blowing effect. The axial blowing assembly 6 adopts the outer cooling ring 61 and the inner cooling ring 62 to be set separately, so as to facilitate the processing of the air flow channel, and a sealing ring is set to ensure the sealing between the outer cooling ring 61 and the inner cooling ring 62;

[0030] In some embodiments, the wire feeding guide wheel 4 is provided with at least two wire grooves 65 along its axial direction and is lengthened.

[0031] In some embodiments, in order to reduce the noise when the airflow flows out of the outlet 22 of the cable channel 2, a sound-absorbing cotton ring is provided at the coaxial part of each group of outlets 22.

[0032] The working principle of the utility model is as follows: a group of extruded cables that need to be blown with water are each installed in the two groups of cable channels 2 in the water blowing box 1, the water blowing box 1 is covered and fixed, and each gas hose is connected to an external compressed air source. At this time, the lateral gas hoses 3 on both sides and the third gas hose 5 in the center directly enter the cable channel 2 to blow water on the circumference of the cable, and the fourth gas hose 63 axially transmits gas into the cable channel 2 to increase the gas flow rate in the tube, thereby achieving a dehydration process for two or more groups of cables at a high line speed.

[0033] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
