Description

TECHNICAL FIELD

[0001] The utility model relates to cable production technical field, concretely relates to a cable extrusion cooling device. BACKGROUND

[0002] In the cable production process, it is necessary to use a cable extruder to wrap a protective layer on the periphery of the cable. The cable extruder has been widely used in the field of cable production, that is, a layer of inner protective layer is wrapped on the surface of the copper wire to protect the core from being cut by the armor. However, the temperature of the inner protective layer is very high after the copper wire is processed in the extrusion machine. At this time, a cooling water tank needs to be set up to cool the cable. After the cable passes through the cooling water tank, water will be left on the surface of the cable. If it is not dried in time, it will affect the processing of the next process of the cable, and finally lead to the decrease of the yield of the cable. In the patent document with the patent application number "CN202421181906.3", a cable extrusion cooler is disclosed. The cooled cable passes through the connection blocks and contacts the water-absorbing cotton on the connection blocks, so that the water on the cable is wiped off by the water-absorbing cotton, avoiding the residual cold water on the cable. However, in the actual use process, in order to make the water-absorbing cotton fully contact with the surface of the cable, the water-absorbing cotton is provided with multiple blocks and has a tendency to move towards the cable by the spring, that is, a gap is left between the two adjacent water-absorbing cottons in the circumferential direction for the movement of the water-absorbing cotton. When the circumference formed by the multiple water-absorbing cottons is consistent with the outer circumference of the cable, the water on the surface of the cable can be completely wiped off. When the outer circumference of the cable is greater than the outer circumference formed by the multiple water-absorbing cottons, there must be a gap between the adjacent water-absorbing cottons. Since the position of the water-absorbing cotton in the circumferential direction of the cable is relatively fixed, it is difficult to completely wipe off the water in the circumferential direction of the cable when the cable passes through the water-absorbing cotton, and the residual cooling liquid may occur. SUMMARY

[0003] To solve the above technical problems, the utility model provides a kind of cable extrusion cooling device, it is rotated by rotating drive mechanism and drives support cylinder, and then the water-absorbing sponge on it rotates in the circumferential direction of cable, and then make water-absorbing sponge can be fully contacted with the circumferential direction of cable, cooling liquid in the circumferential direction of cable can be fully absorbed, wipe off, avoid the residual cooling liquid on cable, improve the cleaning effect of cooling liquid on cable.

[0004] The utility model provides a kind of cable extrusion cooling device to solve the above technical problems, it includes: cold water tank, with water inlet and water outlet;Guide structure, be located in the cold water tank for cable guide;

[0005] The water absorption structure is located on one side of the cold water tank, and comprises a support plate fixed with the cold water tank, a support cylinder rotatably arranged on the support plate, a rotating drive mechanism for driving the rotation of the support cylinder, a plurality of radial holes arranged on the support cylinder in the circumferential direction, a positioning rod movably arranged in the radial hole, an elastic member sleeved on the positioning rod, the two ends of the elastic member being fixed with the inner wall of the support cylinder and the convex ring on the positioning rod respectively, a water absorption sponge arranged on the inner extending end of the positioning rod and a wedge-shaped block arranged on the outer extending end of the positioning rod, a pressing frame fixed on the inner wall of the support cylinder being arranged between the water absorption sponge and the inner wall of the support cylinder, and a driving ring slidably sleeved on the support cylinder, the driving ring being provided with a wedge surface matched with the wedge-shaped block for pushing the wedge-shaped block to move radially along the support cylinder.

[0006] Further, the driving ring is provided with a driving cylinder away from the wedge-shaped block, and the other end of the driving cylinder is fixed with a fixed ring fixed on the support cylinder.

[0007] Further, the guide structure comprises a first guide wheel arranged on both ends of the cold water tank and at least one set of second guide wheels arranged in the cold water tank, the first guide wheel being rotatably arranged on the guide notch on both ends of the cold water tank, the height of the second guide wheel being lower than that of the first guide wheel and being arranged on a vertical plate, and the vertical plate being fixed with the cold water tank.

[0008] Further, the rotating drive mechanism comprises a rotating motor, a transmission gear and a tooth ring arranged on the outer wall of the support cylinder, the rotating motor being fixed on the support plate and the output end being fixed with the transmission gear, and the transmission gear being engaged with the tooth ring.

[0010] Further, the support plate is provided with at least two sets of support rings, and the support rings are connected with the support cylinder through bearings.

[0011] Further, the support cylinder is provided with a plurality of water filtering holes.

[0012] The beneficial effects of the utility model are as follows: the cold water tank is used for water cooling of the extruded cable, the water inlet is used for injecting cooling liquid into the cold water tank, and the water outlet is used for discharging the cooling liquid in the cooling tank. The guide structure is used for guiding the extruded cable so that it can be completely immersed in the cooling liquid.

The support cylinder is provided with a plurality of radial holes in the circumferential direction, and the positioning rod is movably arranged in the radial hole, so that the positioning rod can move along the radial direction of the support cylinder.

The wedge-shaped block arranged on the outer end of the positioning rod can not only limit the positioning rod from being separated from the radial hole to enable it to be stably arranged in the radial hole, but also cooperate with the wedge-shaped surface on the driving ring to enable the positioning rod to drive the water absorption sponge to move in the radial direction of the support cylinder. At this time, when the driving ring moves towards the wedge-shaped block, the wedge-shaped surface extrudes the wedge-shaped block to make it move away from the center of the support cylinder, thereby driving the water absorption sponge to move towards the extrusion frame, the extrusion frame extrudes the water absorption sponge to make it deform, and the cooling liquid in the water absorption sponge is extruded, so that the water absorption sponge can continuously absorb and wipe the cooling liquid on the cable; when the driving ring moves away from the wedge-shaped block, the wedge-shaped surface loses the extrusion of the wedge-shaped block, and the water absorption sponge moves towards the center of the support cylinder under the reset action of the elastic element to extrude the surface of the cable to absorb the cooling liquid. In summary, by using the utility model, the support cylinder is driven to rotate by the rotary driving mechanism, thereby driving the water absorption sponge on it to rotate in the circumferential direction of the cable, and the water absorption sponge can fully contact with the circumference of the cable to fully absorb and wipe the cooling liquid on the circumference of the cable, so as to avoid the residual cooling liquid on the cable and improve the cleaning effect of the cooling liquid on the cable.

Detailed Implementation

[0017] Referring to the accompanying drawings, the specific embodiments of this utility model will be described in detail.

[0018] Reference Figures 1 to 2 This utility model provides a cable extrusion cooling device, including a cold water tank 1, a guiding structure, and a water absorption structure 3. The cold water tank 1 is used to cool the extruded cable with water, the guiding structure is used to guide the extruded cable so that it can be completely immersed in the coolant, and the water absorption structure 3 is used to absorb and wipe away the coolant on the surface of the cable after cooling is completed.

[0019] The cold water tank 1 has an inlet 11 and an outlet 12. The inlet 11 is used to inject coolant into the cold water tank 1, and the outlet 12 is used to discharge the coolant from the cold water tank.

[0020] A guiding structure is installed within the cold water tank 1 to guide the cable. Further, the guiding structure includes first guide wheels 21 located at both ends of the cold water tank 1 and at least one set of second guide wheels 22 located within the cold water tank 1. The first guide wheels 21 are rotatably mounted on guide notches 13 at both ends of the cold water tank 1. The height of the second guide wheels 22 is lower than the height of the first guide wheels 21 and they are mounted on a vertical plate 14, which is fixed to the cold water tank 1. The first guide wheel 21 located on one side of the extruder guides the cable into the coolant in the cold water tank 1, while the first guide wheel 21 at the other end guides the cooled cable into the water-absorbing structure 3, ensuring stable cable movement. The second guide wheels 22, located between the two first guide wheels 21, press the cable into the cold water tank 1, ensuring the cable is fully immersed and maximizing cooling.

[0021] The water-absorbing structure 3 is located on one side of the cold water tank 1, specifically on the side where the cable exits from the cold water tank 1.

[0022] The water absorption structure 3 includes a support plate 31 fixed to the cold water tank 1, which is used to provide rotational support for the support cylinder 32. The support cylinder 32 is rotatably mounted on the support plate 31. Furthermore, the support plate 31 is provided with at least two sets of support rings 311, which are connected to the support cylinder 32 via bearings 312. The arrangement of the two sets of support rings 311 ensures the stability of the support cylinder 32, and the arrangement of the bearings 312 ensures smooth rotation of the support cylinder 32 and reduces wear.

[0023] The support cylinder 32 is driven to rotate by the rotary drive mechanism 33, which in turn causes the multiple water-absorbing sponges 37 on the support cylinder 32 to rotate around the circumference of the cable, ensuring that the outer circumference of the cable can contact the water-absorbing sponges 37.

[0024] Specifically, the rotary drive mechanism 33 includes a rotary motor 331, a transmission gear 332, and a gear ring 323 disposed on the outer wall of the support cylinder 32. The rotary motor 331 is fixed to the support plate 31, and its output end is fixed to the transmission gear 332. The transmission gear 332 meshes with the gear ring 323. At this time, the rotary motor 331 is supported by the support plate 31. When the rotary motor 331 starts, it drives the transmission gear 332 to rotate, which in turn drives the support cylinder 32 to rotate uniformly on the two sets of support rings 311 through the gear ring 323.

[0025] The support cylinder 32 has multiple radial holes 321 arranged in the circumferential direction. At least two sets of radial holes 321 can be provided; in this embodiment, four sets of radial holes 321 are provided and evenly distributed along the circumference of the support cylinder 32. A positioning rod 34 is movably disposed within each radial hole 321. The positioning rod 34 can be square, rhomboid, etc.; in this embodiment, it is set as a square rod to prevent rotation of the positioning rod 34 within the radial hole 321, ensuring that the positioning rod 34 can only move along the radial direction of the support cylinder 32.

[0026] The inner end of the positioning rod 34 is equipped with an absorbent sponge 37, which is used to absorb and wipe away the coolant on the outer surface of the cable. Furthermore, a rubber block 371 is provided on the inner end of the positioning rod 34, and the absorbent sponge 37 is placed on the rubber block 371. The rubber block 371 supports the absorbent sponge 37, allowing it to fully contact the cable. An elastic element 35 is sleeved on the positioning rod 34. The two ends of the elastic element 35 are fixed to the inner wall of the support cylinder 32 and the protruding ring 341 on the positioning rod 34, respectively. The elastic element 35 can be a spring. The elastic element 35 causes the absorbent sponge 37 on the inner end of the positioning rod 34 to tend to move towards the center of the support cylinder 32, thereby pressing it firmly against the surface of the cable, ensuring full contact and facilitating the absorption and wiping away of moisture from the cable surface.

[0027] A compression frame 38, fixed to the inner wall of the support cylinder 32, is provided between the absorbent sponge 37 and the inner wall of the support cylinder 32. The compression frame 38 is used to compress the absorbent sponge 37, squeezing out the coolant from the absorbent sponge 37. Further, the support cylinder 32 is provided with several water-filtering holes to facilitate the discharge of the squeezed-out coolant. Preferably, a water-receiving trough is provided at the bottom of the support cylinder 32 to collect water and squeeze out the coolant. Each absorbent sponge 37 is provided with a corresponding absorbent frame. The absorbent frame is a square frame structure with a strip-shaped groove in the middle. The cross-section of the strip-shaped groove is smaller than the cross-section of the absorbent sponge 37. When the absorbent sponge 37 moves towards the compression frame 38, the absorbent sponge 37 enters the strip-shaped groove and is squeezed within it, squeezing out the coolant from the absorbent sponge 37.

[0028] A wedge-shaped block 36 is provided on the extended end of the positioning rod 34, and a drive ring 39 is slidably sleeved on the support cylinder 32. The drive ring 39 has a wedge-shaped surface 391 that cooperates with the wedge-shaped block 36 to push the wedge-shaped block 36 to move radially along the support cylinder 32. The wedge-shaped block 36 not only prevents the positioning rod 34 from disengaging from the radial hole 321, allowing it to be stably installed in the radial hole 321, but also cooperates with the wedge-shaped surface 391 on the drive ring 39, so that the positioning rod 34 drives the absorbent sponge 37 to move radially in the support cylinder 32. Furthermore, a drive cylinder 392 is provided on the side of the drive ring 39 away from the wedge-shaped block 36, and the other end of the drive cylinder 392 is fixed to a fixing ring 322 fixed on the support cylinder 32. At least two sets of drive cylinders 392 are provided and evenly distributed in the circumferential direction of the drive ring 39 to ensure that the drive ring 39 can move stably and that the squeezing force on each wedge-shaped block 36 is consistent. At this time, when the telescopic shaft of the drive cylinder 392 extends, the drive ring 39 moves towards the wedge block 36, and the wedge surface 391 squeezes the wedge block 36 to move it away from the center of the support cylinder 32. This causes the water-absorbing sponge 37 to move towards the compression frame 38. The compression frame 38 squeezes the water-absorbing sponge 37, causing the water-absorbing sponge 37 to deform and squeeze out the coolant from the water-absorbing sponge 37, so that the water-absorbing sponge 37 can continuously absorb and wipe the coolant on the cable. When the telescopic shaft of the drive cylinder 392 retracts, the drive ring 39 moves away from the wedge block 36, and the wedge surface 391 loses its squeezing of the wedge block 36. Under the reset action of the elastic element 35, the water-absorbing sponge 37 moves towards the center of the support cylinder 32 and is squeezed onto the surface of the cable to absorb the coolant.

[0029] In use, when the wedge-shaped surface 391 on the drive ring 39 is not pressing the wedge block 36, the absorbent sponge 37 is in full contact with the cable surface under the action of the elastic element 35. When the support cylinder 32 rotates under the drive of the rotary drive mechanism 33, it causes the multiple absorbent sponges 37 installed on it to rotate around the circumference of the cable, thereby causing the absorbent sponges 37 to rotate around the moving cable to absorb and dry the coolant on the cable surface. When the absorbent sponge 37 is saturated with water, the drive ring 39 moves towards the wedge block 36, pressing the wedge block 36 to move away from the center of the support cylinder 32, thereby compressing the elastic element 35 and causing the absorbent sponge 37 to move towards the compression frame 38. Under the compression of the compression frame 38, the coolant in the absorbent sponge 37 is squeezed out. Afterwards, when the drive ring 39 loses the compression of the wedge block 36, the absorbent sponge 37 resets under the action of the elastic element 35 and continues to absorb and wipe the coolant on the cable surface.
