Description

Technical Field

[0001] This utility model belongs to the technical field of drying devices, specifically relating to a drying device for a cable extruder. Background Technology

[0002] During cable production, the outer plastic layer of the cable needs to be cooled down. Usually, water cooling is used for rapid cooling. However, after cooling, a large number of water droplets remain on the outer plastic layer of the cable.

[0003] Currently, a common method is to use a sponge to absorb water in conjunction with a fan to dry the outer plastic layer of the cable to eliminate water droplets. However, in actual production, the water absorption capacity of the sponge is limited. Once the sponge reaches its maximum absorption capacity, it can no longer absorb water droplets on the plastic layer. Relying solely on a fan to dry the outer perimeter of the plastic layer is insufficient to guarantee its dryness. At this point, the machine needs to be stopped and a new sponge replaced, affecting the cable production efficiency. Utility Model Content

[0039] The present application will be further described in detail below with reference to the accompanying drawings.

[0040] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0041] Please refer to the following: Figures 1 to 7 This invention describes the cable 50 extruder drying device. The cable extruder drying device includes a U-shaped frame 10, a drying unit 20, and a switching unit 30. The U-shaped frame 10 has a through hole 101 for the cable 50 to pass through. The drying unit 20 includes absorbent sponges 201 disposed inside the U-shaped frame 10, which abut against the outer periphery of the cable 50. At least two absorbent sponges 201 are provided along a first direction, each including two oppositely arranged absorbent blocks 2011. The switching unit 30 corresponds one-to-one with the absorbent blocks 2011. The switching unit 30 includes a mounting plate 301 rotatably connected to the U-shaped frame 10, a power component 302 drively connected to the mounting plate 301, and a clamping assembly connected to the mounting plate 301. The rotation axis of the mounting plate 301 is parallel to the first direction. The power component 302 drives the mounting plate 301 to rotate, and the clamping assembly clamps the absorbent blocks 2011.

[0042] Specifically, the power component 302 is a servo motor.

[0043] The cable 50 extruder drying device provided in this embodiment, compared with the prior art, replaces the traditional whole water-absorbing sponge 201 with two separable water-absorbing blocks 2011; the clamping assembly can realize the fixing and separation of the water-absorbing blocks 2011 and the mounting plate 301. This utility model, by setting a power component 302, enables the mounting plate 301 to have a vertical first working state and a horizontal second working state. In the first working state, the two water-absorbing blocks 2011 abut against each other to wrap the cable 50; in the second working state, the two water-absorbing blocks 2011 separate. Two opposing switching units 30 form a group. By setting multiple groups of switching units 30, at least one group of mounting plates 301 in the switching unit 30 is in the first working state, so the water-absorbing blocks 2011 on the remaining mounting plates 301 can be replaced without stopping the machine, ensuring the production efficiency of the cable 50.

[0044] In some embodiments, see Figure 2 The length direction of the mounting plate 301 is perpendicular to its own rotation axis. The clamping assembly includes two clamping plates 303 and a clamping member 304. The two clamping plates 303 are disposed opposite to each other at both ends of the mounting plate 301 and are slidably connected to the mounting plate 301. The clamping member 304 is connected to the two clamping plates 303 and is used to drive the two clamping plates 303 to move closer or further apart.

[0045] Specifically, the clamping component 304 is a finger cylinder.

[0046] When the absorbent block 2011 needs to be replaced, the clamping member 304 drives the two clamping plates 303 to move away from each other, so that the absorbent block 2011 is separated from the mounting plate 301; after the absorbent block 2011 is replaced, the clamping member 304 drives the two clamping plates 303 to move closer to each other, so that the absorbent block 2011 is fixed to the mounting plate 301.

[0047] The clamping range is expanded by the clamping plate 303 to ensure that the clamping force is applied evenly to the water-absorbing block 2011 and to avoid local deformation of the water-absorbing block 2011. The distance between the two clamping plates 303 can be flexibly adjusted to accommodate water-absorbing blocks 2011 of different sizes, thereby meeting the production needs of cables 50 with different thicknesses.

[0048] Another variation of the clamping assembly is that the clamping assembly can be a vacuum electric suction cup, which is fixed to the mounting plate 301 by negative pressure adsorption. When the vacuum electric suction cup stops working, the water absorption block 2011 separates from the mounting plate 301.

[0049] In some embodiments, see Figure 2The clamping assembly also includes a limiting plate 305 disposed between two clamping plates 303. The surface of the limiting plate 305 is parallel to the surface of the mounting plate 301. A first telescopic member 3011 is fixedly connected between the limiting plate 305 and the mounting plate 301. The telescopic direction of the first telescopic member 3011 is perpendicular to the surface of the limiting plate 305.

[0050] Specifically, the first telescopic component 3011 is a telescopic oil cylinder or hydraulic cylinder.

[0051] Under the action of the telescopic component, the limiting plate 305 abuts against the water-absorbing block 2011, forming a rigid support perpendicular to the clamping direction, effectively preventing the water-absorbing block 2011 from being deformed or shifted under pressure. At the same time, the telescopicity of the first telescopic component 3011 allows the device to adapt to water-absorbing blocks 2011 of different thicknesses, ensuring the stability of the water-absorbing block 2011 and the tightness of its fit with the cable 50. The synergistic effect of the limiting plate 305 and the clamping plate 303 further disperses the clamping stress, avoids local damage to the water-absorbing block 2011, and significantly improves the service life of the water-absorbing block 2011.

[0052] In some embodiments, see Figure 1 The cable 50 extruder drying device also includes a feeding unit 40. There are two feeding units 40, which are arranged on both sides of the cable 50 along a second direction, which is perpendicular to the first direction.

[0053] The feeding unit 40 includes a conveyor 401, a plurality of second telescopic members 402, a plurality of feeding plates 403, and an adsorption member 404. The conveyor 401 is fixed to the U-shaped frame 10. The telescopic direction of the plurality of second telescopic members 402 is perpendicular to the belt surface of the conveyor 401, and the fixed end of the second telescopic member 402 is fixed to the belt surface of the conveyor 401. The plurality of feeding plates 403 correspond one-to-one with the second telescopic members 402, and the feeding plates 403 are fixed to the telescopic ends of the second telescopic members 402. The adsorption member 404 is provided on the side of the feeding plate 403 away from the second telescopic members 402, and is used to adsorb and fix the water-absorbing block 2011 to the feeding plate 403.

[0054] Specifically, the second telescopic component 402 is a telescopic oil cylinder or hydraulic cylinder.

[0055] Optional, see Figure 4 The feeding plate 403 has an air cavity 4031 inside, and multiple air holes 4032 communicating with the air cavity 4031 are formed on the surface of the feeding plate 403. The adsorption element 404 is connected to the air cavity 4031 and is used to reduce the air pressure in the air cavity 4031. The adsorption element 404 can be an air pump. The array layout of the air holes 4032 ensures a uniform distribution of adsorption force, avoids local deformation of the water absorption block 2011, and effectively ensures the adsorption stability between the water absorption block 2011 and the feeding plate 403 by uniformly distributing the adsorption force.

[0056] Optionally, the adsorption component 404 can be an electromagnetic component. In this case, the water absorption block 2011 is provided with ferromagnetic material, which is located on the side of the water absorption block 2011. When the electromagnetic component is energized, it generates an attractive force to adsorb the ferromagnetic material, which fixes the water absorption block 2011 to the feeding plate 403. When the electromagnetic component is de-energized, the attractive force disappears, and the water absorption block 2011 separates from the feeding plate 403.

[0057] The workers placed the dry absorbent blocks 2011 at intervals on the feeding plate 403, that is, the first feeding plate 403 was empty, the second feeding plate 403 had dry absorbent blocks 2011 on it, the third feeding plate 403 was empty, and the last feeding plate 403 had dry absorbent blocks 2011 on it.

[0058] After the conveyor 401 moves the empty feeding plate 403 above the water-absorbing block 2011 to be replaced, the second telescopic member 402 extends downward to align the empty feeding plate 403 with the water-absorbing block 2011 to be replaced. The corresponding adsorption member 404 is activated to fix the water-absorbing block 2011 to be replaced with the empty feeding plate 403. Then, the second telescopic member 402 moves upward to detach the water-absorbing block 2011 from the mounting plate 301. The conveyor 401 continues to work to align the feeding plate 403 containing the dry water-absorbing block 2011 with the empty mounting plate 301. The second telescopic member 402 extends downward to move the dry water-absorbing block 2011 to abut against the empty mounting plate 301. The corresponding adsorption member 404 stops working, allowing the dry water-absorbing block 2011 to fall onto the empty mounting plate 301. This is a complete water-absorbing block 2011 replacement process.

[0059] Feeding units 40 are symmetrically arranged on both sides of the cable 50. In conjunction with the horizontal movement of the conveyor 401 and the vertical lifting drive of the second telescopic component 402, the fully automatic conveying and precise positioning of the water-absorbing block 2011 is realized. The adsorption component 404 firmly adsorbs the water-absorbing block 2011 onto the surface of the feeding plate 403, preventing it from falling off or shifting during transportation. This greatly reduces manual intervention and significantly improves the replacement efficiency of the water-absorbing block 2011 and the continuity of the drying operation.

[0060] In some embodiments, see Figure 5 and Figure 6 The drying unit 20 also includes a wiper ring and a pneumatic component. The wiper ring, the absorbent sponge 201 and the pneumatic component are arranged sequentially along the first direction. The wiper ring includes a ring body 202 and a wiper brush 203 detachably connected to the inner wall of the ring body 202. The wiper brush 203 abuts against the outer periphery of the cable 50. The pneumatic component is used to supply air to the cable 50.

[0061] Specifically, the pneumatic component can be an air pump.

[0062] The water-soaked cable 50 is first scraped off by the action of the water scraper ring, and then most of the water on the surface of the cable 50 is removed by the water-absorbing sponge 201. Finally, the cable 50 is dried by the blowing action of the pneumatic component. The multi-stage drying system improves the overall drying effect.

[0063] In some embodiments, see Figure 5 and Figure 7 The drying unit 20 also includes a drying ring 204. The drying ring 204 has an annular cavity 2041 connected to the pneumatic component. The inner wall of the drying ring 204 has a plurality of drying holes 2042 connected to the annular cavity 2041. The plurality of drying holes 2042 are spaced apart around the central axis of the drying ring 204.

[0064] The pneumatic component's blowing action causes the air pressure inside the annular cavity 2041 to be higher than the external air pressure, thereby compressing the internal air to the drying hole 2042 to blow air onto the cable 50. The drying hole 2042 is set around the central axis of the drying ring 204 so that the drying hole 2042 always faces the center of the cable 50, thus ensuring that the outer periphery of the cable 50 is dried evenly.

[0065] In some embodiments, see Figure 6 The squeegee 203 includes multiple spliced ​​brushes 2031, which are arranged in a circle. The inner wall of the ring body 202 has an annular mounting cavity 2021. One end of the spliced ​​brush 2031 is inserted into the mounting cavity 2021. A patch 2022 is provided in the mounting cavity 2021. An elastic member 2023 is fixed between the patch 2022 and the ring body 202. The elastic member 2023 has a pre-tightening force that causes the patch 2022 to abut against the spliced ​​brush 2031.

[0066] Specifically, the elastic element 2023 is a spring.

[0067] Optionally, there can be multiple patches 2022, which are evenly spaced around the central axis of the ring body 202.

[0068] Optionally, the patch 2022 can be a single patch, which is arranged in a ring.

[0069] Multiple splicing brushes 2031 are arranged in a circular mounting cavity 2021 on the inner wall of the wiper ring. Splicing brushes 2031 of different lengths can be installed through a detachable connection, thereby adapting to cables 50 of different thicknesses.

[0070] During installation, the splicing brush 2031 is inserted between the patch 2022 and the inner wall of the squeegee ring. The elastic element 2023 causes the patch 2022 to fix the splicing brush 2031 in the mounting cavity 2021, making installation and removal very convenient.

[0071] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
