Description

Technical Field

[0001] The invention belongs to the technical field of cable production, and in particular relates to a glue coating device for twisting watertight cable conductors. Background Art

[0002] Watertight cables, also known as deepwater sealed cables, are cables with longitudinal or transverse watertight properties that can be used in underwater ships or devices. They are widely used in various marine resource exploration activities. In order to prevent them from being damaged by long-term immersion in corrosive seawater, water-blocking glue is generally added during the cable production process to fill the gaps between several conductive wires, so as to achieve the purpose of sealing the cable during the working process.

[0003] The current existing glue coating method is usually carried out by coating the water-blocking glue on the surface of the cable core after the cable core is twisted. However, in actual operation, the adjacent conductive wires are in close contact after twisting, resulting in poor penetration of the water-blocking glue into the gap inside the contact surface of the adjacent conductive wires. Of course, there is also a method of first coating the conductive wire with glue and then twisting it. However, the diameter of the conductive wire is small and the adhesion effect of the water-blocking glue is poor. During the twisting process, the water-blocking glue will fall off due to its own rotation, which will also result in poor filling effect of the water-blocking glue on the gap inside the contact surface of the adjacent conductive wires.

[0018] like Figure 6As shown, the present invention is a glue coating device for twisting a watertight cable conductor, which is arranged at the rear end of the cable core twisting device. First of all, it should be noted that the gap on the inner side of the contact surface of adjacent conductive wires refers to the smaller arc area formed between the contact surfaces of the middle conductive wire 31 and the outer conductive wire 30. It should also be noted that the cable core twisting device is a prior art, and its purpose is to twist a plurality of conductive wires (the conductive wires are generally divided into the middle conductive wire 31 and the outer conductive wire 30) into an integrated travel cable core, which includes a traction structure, a twisting structure and a rotating structure, etc., which will not be elaborated here. It should be noted that during the operation of the cable core twisting device, some can drive the cable core to rotate, and some only require the conductive wire to rotate to complete the twisting, which can be selected according to actual conditions.

[0019] like Figure 1-Figure 5 As shown, the glue coating device includes a bottom plate 1, a vertical plate 2 is provided on the bottom plate 1, one end of the vertical plate 2 is fixed on the bottom plate 1, a mounting hole is provided on the other end of the vertical plate 2, a rotating bearing is provided in the mounting hole, the outer ring of the rotating bearing is fixed on the inner side surface of the mounting hole, a rotating tube 3 is provided on the inner ring of the rotating bearing, one end of the rotating tube 3 is fixed on the inner ring of the rotating bearing, a driven wheel 4 is provided on the rotating tube 3, a rotating motor 7 is provided on the mounting plate 8, a driving wheel 5 is provided on the output end of the rotating motor 7, a driving belt 6 is provided on the driving wheel 5, and the driving belt 6 is wound around the driving wheel 5 and the driven wheel 4, a mounting plate 8 is provided on the other end of the rotating tube 3, one end of the mounting plate 8 is fixed on the end surface of the rotating tube 3, a first adjusting screw 9 is provided on the other end of the mounting plate 8, the degree of extrusion and bending and adapting to different wire diameters are adjusted, the first adjusting screw 9 is threadedly connected to the mounting plate 8, and a wire pressing wheel 10 is provided on the end of the first adjusting screw 9, and the wire pressing wheel 10 is used to extrude the cable core that has been twisted so that the cable core is bent under force.

[0020] The working principle of the above technical solution is: First, the device is installed at the rear end of the cable core twisting device. The rear end refers to the part that has been twisted to form the cable core. During installation, the cable core needs to pass through the rotating tube 3, that is, at this time, only the length of the first adjusting screw 9 needs to be adjusted. Under the action of the rotating motor 7, the crimping wheel 10 can be driven to rotate, and the crimping wheel 10 can be used to rotate and squeeze the cable core. The cable core can be squeezed in any direction, so that a gap can be generated between any two conductive wires, which is convenient for glue coating. During the squeezing process, the cable core will be bent. When bending, Gaps will be formed between the several wound conductive wires on the protruding end of the bending part, and then when the glue coating operation is performed, the water-blocking glue 32 can penetrate into the adjacent conductive wires through the gaps, thereby improving the filling effect of the water-blocking glue 32 on the cable core, thereby improving the waterproof effect. Of course, it is not difficult to understand that the number of the first adjusting screw 9 and the wire pressing wheel 10 can be set to multiple groups, so that the cable core can be bent at multiple positions, further improving the filling effect of the water-blocking glue 32, and the wire pressing wheel 10 can also be designed as a wire barrel, so that the cable core can pass through the wire barrel.

[0021] In one practicable manner, an annular cylinder 13 is provided on the outer side of the wire crimping wheel 10, annular baffles are provided at both ends of the annular cylinder 13, a plurality of first glue inlet pipes 14 are provided on the circumference of the annular cylinder 13, the ends of the first glue inlet pipes 14 are connected to the interior of the annular cylinder 13 and are directed toward the wire crimping wheel 10, a first collecting box 15 is provided below the annular cylinder 13, a fixing plate 16 is provided inside the first collecting box 15, a collecting pipe 17 is provided on the fixing plate 16, the outer side surface of one end of the collecting pipe 17 is connected to the fixing plate 16, the outer side surface of the other end of the collecting pipe 17 is fixed on the annular cylinder 13 and is connected to the interior of the annular cylinder 13, and the annular cylinder 13 is concentrically arranged with the mounting hole on the vertical plate 2.

[0022] With this arrangement, the position of the annular cylinder 13 is fixed and will not rotate, so it is easy to install components such as the pumping pipe. The water-blocking glue 32 is pumped into the annular cylinder 13 through the first glue inlet pipe 14 to contact the cable core for gluing. The excess water-blocking glue 32 flows through the collecting pipe 17 to the first collecting box 15 to be collected for reuse.

[0023] In one practicable manner, the first glue inlet pipe 14 is connected to the annular cylinder 13 via a universal joint, and the inclination angle of the first glue inlet pipe 14 can be changed so that it can always point to the crimping wheel 10 and adapt to the height of the crimping wheel 10 .

[0024] In one feasible manner, a mounting frame 18 is provided on the mounting plate 8, and a plurality of correction wheels 19 which are staggered up and down are provided on the mounting frame 18. A second adjusting screw 20 is provided on each of the correction wheels 19, and the second adjusting screw 20 is threadedly connected to the mounting frame 18. The vertical plate 2 is located between the mounting frame 18 and the crimping wheel 10. The setting of the correction wheel 19 can squeeze and straighten the bent cable core under the action of the traction component, so as to facilitate the subsequent gluing operation on the outer surface of the cable core.

[0025] In one practicable manner, a connecting plate 29 is provided on the rear side surface of the mounting frame 18, a rubber filling tube 22 is provided on the connecting plate 29, one end of the rubber filling tube 22 is fixed on the connecting plate 29, a plurality of second rubber feed tubes 23 are provided on the rubber filling tube 22, one end of the second feed tube is fixed on the rubber filling tube 22 and is connected to the interior of the rubber filling tube 22, a plurality of annularly evenly distributed bristles 24 are provided on the inner side surface of the other end of the rubber filling tube 22, one end of the bristles 24 is connected to the inner side surface of the rubber filling tube 22, and the other end of the bristles 24 is arranged to point to the center of the rubber filling tube 22, a second collecting box 21 is provided below the rubber filling tube 22, and the second collecting box 21 is fixedly connected to the base plate 1.

[0026] The setting of the glue filling tube 22 and the second glue inlet tube 23 can be used to apply glue to the outer surface of the cable core after straightening, and the setting of the bristles 24 can evenly spread the irregularly distributed water-blocking glue 32 (water drop-shaped or other raised water-blocking glue 32) adhered to the outer surface of the cable core, thereby improving the uniformity of glue application and scraping off excessively adhered water-blocking glue 32.

[0027] In one feasible manner, a sleeve is provided on one end of the bristle 24 connected to the glue filling tube 22, the end of the bristle 24 is located in the sleeve, and the outer side surface of the sleeve is threadedly connected to the end side surface of the glue filling tube 22, that is, by setting the height of the sleeve, the contact distance between the end of the bristle 24 and the cable core can be changed, and thus the thickness of the water-blocking glue 32 adhering to the cable core can be controlled.

[0028] In one feasible manner, a support plate 28 is provided at the rear end of the glue filling tube 22, one end of the support plate 28 is fixed on the bottom plate 1, a heating tube 25 is provided on the other end of the support plate 28, the outer side surface of the heating tube 25 is fixed on the support plate 28, a heating wire 26 is provided on the outer side surface of the heating tube 25, the heating wire 26 is wound on the heating tube 25, the setting of the heating tube 25 can quickly solidify the water-blocking glue evenly spread on the cable core, and at the same time, the cable core is heated by heat radiation inside the heating tube 25, and the heating effect is better and more uniform. As for the heating temperature, it is generally 200 degrees Celsius, which can be designed according to the type of water-blocking glue 32 selected.

[0029] In one feasible manner, a friction plate 27 is provided in the middle of the heating tube 25, one end of the friction plate 27 is arranged to point to the center of the heating tube 25, and the other end of the friction plate 27 is slidably connected to the heating tube 25. The purpose of arranging the friction plate 27 in the middle is that when the cable core is driven by the traction structure and the water-blocking adhesive 32 moves to the middle position, the water-blocking adhesive 32 has begun to solidify, but has not been completely solidified, and is in a relatively soft state at this time, that is, under the rotation of the friction plate 27 driven by the cable core or the heating tube 25, the semi-solidified water-blocking adhesive 32 on its outer surface is in rotational contact with the friction plate 27, and the water-blocking adhesive 32 on the outer surface of the cable core can be rotationally extruded and shaped, that is, extruded and shaped into a columnar shape, and the smoothness of the surface of the water-blocking adhesive 32 can be improved, thereby facilitating the later construction of cable sheathing and other processes on the cable core.

[0030] In one feasible method, a support column 11 is provided at the front end of the annular cylinder 13, one end of the support column 11 is fixed on the base plate 1, and a guide wheel 12 is provided at the other end of the support column 11 to enhance the guiding effect on the bending part of the cable core and avoid contact with the middle hole wall of the annular cylinder 13. Of course, a guide wheel 12 can also be arranged between the correction wheel 19 and the vertical plate 2, which can be designed according to actual conditions and will not be elaborated on here.

[0031] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
