Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a drying equipment for cable processing. Background Technology

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power plant lead-out lines, internal power supply for industrial and mining enterprises, and underwater power transmission lines across rivers and seas. After the cables are manufactured and processed, they need to be immersed in water for cooling. After cooling, they also need to be sent to drying equipment for drying.

[0003] Patent document CN222211120U discloses a drying equipment for cable production and processing, which includes a processing box, a ring pipe, baffles, a winding roller, and a dust removal mechanism. It mainly achieves the following: using baffles to separate the lower area to prevent water evaporation to the upper area; using a heat pump, air inlet pipe, ring pipe, and air outlet pipe to blow air onto the passing cables for drying; and using a sponge to clean surface stains and water stains. However, the above-mentioned prior art still has the following problems in use: 1. The cable reels are distributed vertically within the processing box. Due to the limited internal space of the processing box, the hoisting, disassembly, and position adjustment of the reels are cumbersome, which is not conducive to efficient reel changing operations; 2. There is a lack of axial cable guiding structure, and the cable is prone to accumulation and displacement on the surface of the reel during winding, making it impossible to achieve uniform distribution, affecting the utilization rate of the reel and subsequent cable unwinding; 3. The reels are located inside the processing box, and even with baffles, it is still difficult to completely avoid the secondary impact of the humid and hot environment inside the box on the reels and wound cables, resulting in low drying efficiency. Utility Model Content

[0004] This utility model mainly provides a drying device for cable processing, which solves the problems of existing technology: cable reels are located inside the processing box, making disassembly and assembly inconvenient; wound cables tend to accumulate on the cable reels; and the risk of poor drying effect due to the humid and hot environment inside the box is difficult to avoid.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A drying device for cable processing includes a mounting platform with an open drying chamber on the platform. An annular air outlet duct is installed inside the drying chamber and connected to a hot air production line via an air inlet duct. Multiple air outlets are arranged in a ring on the annular air outlet duct. A connecting plate is detachably connected to the open drying chamber on the outer side of the annular air outlet duct, and a sponge is installed on the inner side of the connecting plate. A collection trough is provided on the mounting platform on one side of the opening of the open drying chamber, and a first rotating bracket for detachably connecting a cable reel is provided in the collection trough. A second rotating bracket for detachably connecting the cable reel is provided on the mounting platform on the other side of the open drying chamber, and a drive motor for rotating the cable reel on the second rotating bracket is provided. A guide mechanism for driving the axial movement of the cable is provided on the mounting platform on the feeding side of the second rotating bracket. The drive motor can be any type of electric motor from the prior art, as long as its technical principle can be implemented, such as a DC brushless motor with a reducer, a servo motor with an encoder, or a three-phase asynchronous motor with variable frequency speed control. Specifically, the front end of the open-type drying oven, i.e., the inlet end, has an opening for mounting connecting plates and other components. The rear end of the open-type drying oven, i.e., the outlet end, has a detachable tail plate with an outlet hole smaller than the front opening, allowing a large amount of heat to flow out from the sponge. The air outlet is also angled towards the front opening of the open-type drying oven. Hot air production equipment can use heat pump hot air blowers, electric heating hot air blowers, etc. In operation, the cable, after being cooled by immersion in water, is transported to the first rotating bracket via its cable reel and mounted therefore to rotate. The cable then passes through the front opening of the open-ended drying chamber and exits through the cable hole at the rear end. It first passes through a sponge at the opening, then through the annular air outlet pipe inside the drying chamber, and is finally fixed to the cable reel on the second rotating bracket. A drive motor rotates the cable reel on the second rotating bracket to rewind the dried cable. The cable reel on the first rotating bracket rotates passively with the cable, and any liquid dripping from its surface falls into the collection tank below. During transport, the sponge inside the connecting plate at the front opening of the open-ended drying chamber presses against the cable surface, wiping away any residual water and dirt. Hot air generated by the hot air production equipment is then delivered through the inlet pipe to the annular outlet pipe and evenly blown from the annularly distributed outlets onto the cable passing through the center of the annular outlet pipe, thus drying the cable surface.This structure separates the first and second rotating brackets for mounting the cable reel from the open drying chamber into multiple parts and mounts them on the mounting platform. This eliminates the space limitations inside the open drying chamber, making it easier to handle the cable reel during hoisting and disassembly. Simultaneously, since the cable reel collecting the dried cable is not inside the open drying chamber, it effectively avoids the impact of the hot and humid air inside the drying chamber on the cable reel and the wound cable, thus preventing the cable from becoming damp and ensuring stable drying results. Furthermore, wiping the cable with a sponge first removes surface water and dirt, followed by all-around drying with hot air from the annular exhaust duct, improving cable surface cleanliness and drying efficiency. The guide mechanism drives the cable to move axially back and forth on the cable reel, achieving uniform winding and effectively avoiding one-sided accumulation and overlapping during winding. Finally, a collection trough collects dripping liquid from the cable, preventing liquid turbulence from contaminating the mounting platform or floor, effectively reducing on-site cleaning workload.

[0007] Furthermore, the open drying box is symmetrically equipped with electric push rods. The output end of each electric push rod extends through the open drying box and is fitted with a connecting frame. A pressing guide rod is mounted on the connecting frame and is slidably connected to the open drying box. The connecting frame is detachably connected to the connecting plate. The electric push rods can be any type of existing technology, as long as their working principle is implemented, such as DC electric push rods or stepper electric push rods. Using this structure, the electric push rods drive the connecting frame to move inward or outward. This serves two purposes: first, it adjusts the position of the sponge, increasing or decreasing the pressure of the sponge on the cable surface to ensure effective wiping; second, when the sponge is saturated with water, there is no need to disassemble the connecting plate. The electric push rods on both sides extend synchronously, pushing the connecting frame closer together. The connecting frame then presses the sponge on the connecting plate, squeezing out the water accumulated inside the sponge.

[0008] Furthermore, the connecting plate is provided with a T-shaped insert, and the connecting frame has a T-shaped slot for inserting the T-shaped insert. The inner side of the T-shaped slot has an integrally formed inner baffle to prevent the T-shaped insert from over-inserting. In use, the T-shaped insert is inserted through the outer opening of the T-shaped slot to detachably connect the connecting plate to the connecting frame. This structure simplifies assembly and disassembly, and the T-shaped structure provides anti-misalignment and anti-misalignment protection, ensuring accurate assembly of the connecting plate each time.

[0009] Furthermore, both the first and second rotating brackets are symmetrically rotatably connected to connecting discs, which are detachably connected to the outer side of the cable reel via bolts. The rotating shaft of the connecting disc on either side of the second rotating bracket is fixedly connected to the output shaft of the drive motor. The connecting discs can be rotatably connected to the first or second rotating bracket in any existing manner, such as having a rotating shaft on the outer side of the connecting disc, which is rotatably connected to a corresponding position via a bearing assembly. In use, the two end faces of the cable reel are aligned with the symmetrically rotatably connected connecting discs on the first and second rotating brackets, respectively. Bolts are passed through the threaded holes of the connecting discs and the pre-drilled holes on the end faces of the cable reel to secure them, thus achieving detachable installation of the cable reel. Then, the drive motor drives the connecting disc on one side of the second rotating bracket to rotate, thereby causing the cable reel on it to wind up. This structure, using bolts to adjust the connecting discs and cable reel, is simple in structure, easy to assemble and disassemble, and the bolt connection provides sufficient tightening force to prevent the cable reel from sliding relative to the connecting disc during rotation.

[0010] Furthermore, the guiding mechanism includes a guide frame mounted on the mounting platform, a reciprocating screw rotatably connected to the guide frame, and a reciprocating guide rod fixedly connected to the guide frame. A reciprocating slider is threaded onto the reciprocating screw, and a guide ring for the cable to pass through is provided on the reciprocating slider. The reciprocating slider is slidably connected to the reciprocating guide rod. The drive motor drives the reciprocating screw to rotate through a transmission assembly. The transmission assembly can be any existing type, such as a chain drive assembly, belt drive assembly, gear drive assembly, etc. In use, while the drive motor drives the cable reel on the second rotating bracket to wind up, the transmission assembly simultaneously drives the reciprocating screw to rotate synchronously. When the screw rotates, the reciprocating slider reciprocates on the reciprocating screw under the constraint of the reciprocating guide rod. This structure allows the cable to move axially back and forth on the cable reel via a guide mechanism, achieving uniform winding of the cable on the reel and avoiding problems such as single-sided accumulation and overlapping during winding. Furthermore, the guide mechanism is driven by a drive motor through a transmission component, eliminating the need for an additional independent motor. Simultaneously, the guiding and winding actions are synchronized by the same drive motor, effectively preventing cable pulling or loosening caused by asynchronous power.

[0011] Beneficial effects: The first and second rotating brackets for installing the cable reel are separated from the open drying box and installed on the mounting platform, freeing it from the space limitations inside the open drying box and ensuring easier operation during cable reel hoisting and disassembly. Simultaneously, since the cable reel collecting the dried cable is not inside the open drying box, it effectively avoids the impact of the hot and humid air inside the drying box on the cable reel and the wound cable, thus preventing the cable from becoming damp and ensuring stable drying results. Furthermore, wiping the cable with a sponge first removes surface water stains and dirt, followed by all-around drying with hot air from the annular exhaust duct, improving cable surface cleanliness and drying efficiency. The guide mechanism drives the cable to move axially back and forth on the cable reel, achieving uniform winding of the cable on the reel and effectively avoiding problems of one-sided accumulation and overlapping during winding. Finally, a collection trough collects dripping liquid from the cable, preventing liquid turbulence from contaminating the mounting platform or floor, effectively reducing on-site cleaning workload.

A collection trough 6 is provided on the mounting platform 1 on one side of the opening of the open drying chamber 2, and a first rotating bracket 7 for detachably connecting a cable reel is provided inside the collection trough 6. A second rotating bracket 8 for detachably connecting a cable reel is provided on the mounting platform 1 on the other side of the open drying chamber 2, and a drive motor 9 for driving the cable reel on the second rotating bracket 8 to rotate is provided. A guide mechanism 10 for driving the axial movement of the cable is provided on the mounting platform 1 on the feeding side of the second rotating bracket 8. The open drying chamber 2 is symmetrically equipped with electric push rods 11. The output end of the electric push rod 11 extends into the open drying chamber 2 and is equipped with a connecting frame 12. The connecting frame 12 is equipped with a pressing guide rod 13, which is slidably connected to the open drying chamber 2. The connecting frame 12 is detachably connected to the connecting plate 4. The connecting plate 4 is equipped with a T-shaped insert 14, and the connecting frame 12 has a T-shaped slot 15 that mates with the T-shaped insert 14. The first rotating bracket 7 and the second rotating bracket 8 are symmetrically rotatably connected with connecting discs 16. The connecting discs 16 are detachably connected to the outer side of the cable reel by bolts. The rotating shaft of the connecting disc 16 on either side of the second rotating bracket 8 is fixedly connected to the output shaft of the drive motor 9. The guiding mechanism 10 includes a guide frame 1001 mounted on the mounting platform 1, a reciprocating screw 1002 rotatably connected to the guide frame 1001, and a reciprocating guide rod 1003 fixedly connected to the guide frame 1001. A reciprocating slider 1004 is threadedly connected to the reciprocating screw 1002, and a guide ring 1005 for cable passage is provided on the reciprocating slider 1004. The reciprocating slider 1004 is slidably connected to the reciprocating guide rod 1003. The drive motor 9 drives the reciprocating screw 1002 to rotate through a transmission assembly.In use, the cable, after being cooled by immersion in water, along with its cable reel, is transported to the first rotating bracket 7 and installed on it for rotation. The cable then passes through the front opening of the open drying chamber 2 and exits through the cable hole at the rear end. The cable first passes through the sponge 5 at the opening, then through the annular air outlet 3 inside the open drying chamber 2, and is then fixed to the cable reel on the second rotating bracket 8. The cable reel on the second rotating bracket 8 is driven by the drive motor 9 to rotate actively, thereby winding up the dried cable. The cable reel on the first rotating bracket 7 is passively rotated by the cable, and the liquid dripping from the surface of the cable falls into the collection tank 6 below. During the cable transport, the sponge 5 inside the connecting plate 4 at the front opening of the open drying chamber 2 presses against the cable surface to wipe it and remove residual water stains and dirt. Then, the hot air generated by the hot air production equipment is delivered to the annular air outlet 3 through the air inlet pipe, and then blown evenly from the annularly distributed air outlets onto the cable passing through the center of the annular air outlet 3 to dry the cable surface. This structure separates the first rotating bracket 7 and the second rotating bracket 8 for mounting the cable reel from the open drying chamber 2 into multiple parts and installs them on the mounting platform 1. This eliminates the space limitations inside the open drying chamber 2, ensuring easier operation of the cable reel during hoisting and disassembly. Simultaneously, since the cable reel collecting the dried cable is not inside the open drying chamber 2, it effectively avoids the impact of the hot and humid air inside the drying chamber on the cable reel and the wound cable, preventing the cable from becoming damp and ensuring stable drying results. Furthermore, the cable is first wiped with a sponge 5 to remove surface water and dirt, and then dried omnidirectionally by hot air from the annular exhaust duct 3, improving the cleanliness of the cable surface and drying efficiency. The guide mechanism 10 drives the cable to move axially back and forth on the cable reel, achieving uniform winding of the cable on the reel and avoiding problems of single-sided accumulation and overlapping during winding. Finally, a collection trough 6 collects the liquid dripping from the cable, preventing liquid turbulence from contaminating the mounting platform 1 or the ground, effectively reducing on-site cleaning workload.
