Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable production drying device. Background Art

[0002] Cable is a wire product used to transmit electrical energy or signals. When producing cables, an extruder is required to use the extrusion process to extrude materials such as plastic or rubber into the insulation layer or protective layer of the cable to provide electrical isolation and insulation protection between the cable conductor and the external environment.

[0003] When the cable is extruded, the insulation layer or protective layer of the cable will experience a high temperature state. After extrusion, it is usually introduced into a water tank. The high specific heat capacity and thermal conductivity of water are used to quickly transfer the heat on the cable surface to the water, thereby accelerating the cooling and solidification of the cable insulation layer.

[0004] After the cable is led out of the water tank, moisture will adhere to the surface of the cable. The moisture remaining on the cable will accelerate the aging process of the cable and shorten the service life of the cable. The moisture will also cause electrochemical corrosion, posing a threat to the safe use of the cable.

DETAILED DESCRIPTION

[0021] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: a cable production drying device, comprising a pay-off roller 1, a drying component is provided on the right side of the pay-off roller 1, and a take-up roller 3 is provided on the right side of the drying component.

[0023] Both ends of the roller shaft of the take-up roller 3 are rotatably connected to the support frame 4 through bearings. One end of the roller shaft of the take-up roller 3 is transmission-connected to the output end of the drive motor 5. The drive motor 5 is fixedly connected to the support frame 4. When the drive motor 5 is started, the roller shaft of the take-up roller 3 is driven to rotate through the output end, thereby driving the take-up roller 3 to rotate for the winding operation.

[0024] The drying assembly includes a box body 6, a cavity 7 is defined in the box body 6, a cylinder 9 is fixedly provided in the box body 6, and the cylinder 9 is arranged along the transmission direction of the cable, that is, the axis of the cylinder 9 is parallel to the transmission direction of the cable.

[0025] Both ends of the cylinder 9 respectively penetrate to the outside of the side wall of the box body 6, and a cavity 2 10 is opened in the cylinder 9. The diameter of the cavity 2 10 is larger than the diameter of the cable. Specifically, the diameter of the cavity 2 10 is 1.3 times the diameter of the cable to be processed.

[0026] A plurality of through holes 11 are evenly formed on the cavity wall of the cylinder 9 located inside the cavity 1 7 , and the cavity 2 10 is connected to the cavity 1 7 via the through holes 11 .

[0027] Several groups of arc-shaped elastic pressure plates 12 are fixedly connected to the inner wall of cavity 2 10. Each group of arc-shaped elastic pressure plates 12 includes multiple groups of arc-shaped elastic pressure plates 13. The arc-shaped elastic pressure plates 13 are made of elastic memory material. One end of the arc-shaped elastic pressure plate 13 is fixedly connected to the inner wall of the cylinder 9, and the other end is inclined toward the axis of the cylinder 9 along the cable transmission direction.

[0028] In this embodiment, there are four groups of arc-shaped elastic pressure plates 13, and the four groups of arc-shaped elastic pressure plates 13 form a frustum-shaped cavity 2. A water-absorbing sponge 14 is fixedly connected to one side of the four groups of arc-shaped elastic pressure plates 13 near the axis of cavity 2 10. When the cable passes through the frustum-shaped cavity 2 formed by the four groups of arc-shaped elastic pressure plates 13, the water-absorbing sponge 14 contacts the outer surface of the cable and absorbs moisture from the surface of the cable through its own water absorption performance.

[0029] The diameter of the side of the frustum-shaped cavity 2 facing the take-up roller 3 is smaller than the diameter of the cable, so that when the cable passes through the frustum-shaped cavity 2, the squeezing friction of the arc-shaped elastic pressure plate 13 and the water-absorbing sponge 14 on the cable will not cause damage to the cable skin.

[0030] An air suction port 15 is provided on the cylinder 9 between two adjacent sets of arc-shaped elastic pressure plate groups 12 . The air suction port 15 is connected to an air duct 16 . The air duct 16 extends to the outside of the box body 6 and is connected to the air inlet of the induced draft fan 17 .

[0031] The portion of the air duct 16 located outside the box body 6 is connected to a condenser 18 , and a water outlet pipe of the condenser 18 is connected to a water tank 19 .

[0032] A heating element is fixedly connected to the inner wall of the cavity 7, and the heating element is used to heat and dry the cable in the cylinder 9. The heating element includes but is not limited to a heating plate, and the temperature at which the heating element 8 dries the cable will not cause the cable skin to expand.

[0033] In this embodiment, the cable on the pay-off roller 1 passes through the cylinder 9 and is fixed to the take-up roller 3 , and then the drive motor 5 is started to make the take-up roller 3 reel the cable.

[0034] During the winding process, the cable enters the cavity 2 10 located in the cavity section of the box 6, and the heating element 8 is started to dry the surface of the cable. The temperature of the heating element 8 drying the cable will not cause the cable skin to expand.

[0035] At the same time, the cables pass through the multiple groups of cone-shaped cavities 2 in sequence, so that the multiple groups of absorbent sponges 14 located in the second cavity 10 perform a contact-type wiping treatment on the cable surface, thereby performing a multi-stage drying treatment on the cable.

[0036] When the cable passes through the frustum-shaped cavity 2, the squeezing friction of the arc-shaped elastic pressure plate 13 and the water-absorbing sponge 14 on the cable will not cause damage to the cable skin.

[0037] At the same time, the heating element 8 dries the water-absorbing sponge 14 to prevent the water-absorbing sponge 14 from being too wet, resulting in an ineffective drying effect on the cable.

[0038] At the same time, the induced draft fan 17 is started to suck the humid air in the cavity 2 10 into the air duct 16 through the air suction port 15, and the humid air is dried under the condensation action of the condenser 23. The water attached to the condenser 23 flows into the water tank 2 through the water outlet pipe of the condenser 23.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the above embodiments, or that some of the technical features may be replaced with equivalents.
