Abstract
Description
Technical Field
[0001] This application relates to the field of optical cable processing technology, specifically to a drying device for optical cable production. Background Technology
[0002] In the production of optical cables, the secondary coating process is a crucial step. This process involves selecting suitable polymer materials and using extrusion to coat the optical cable with a loose tube, while simultaneously filling the space between the tube and the optical fiber with a special grease that provides both viscosity and waterproof protection. After the secondary coating process, the surface temperature of the optical cable is high, requiring it to be placed in a cooling tank for cooling. Since water droplets will adhere to the surface of the cable after placement in the cooling tank, it is necessary to dry the surface again.
[0003] An existing patent (publication number: CN220135999U) discloses a rapid drying device for optical cable production, including a support base. An equipment box is connected to one side of the upper end of the support base. A bearing seat is provided on the upper end of one side wall of the equipment box. A drying cylinder is rotatably mounted inside the bearing seat. A first rotating seat and a second rotating seat are rotatably sleeved at both ends of the outer wall of the drying cylinder. A protective cylinder is connected between the first and second rotating seats and is movably sleeved outside the drying cylinder. Support columns are connected to the lower ends of both the first and second rotating seats, and the bottoms of both support columns are fixedly connected to the upper end of the support base. This invention enables comprehensive drying of the internal cables, resulting in rapid drying with better drying effect. It also allows for timely discharge of steam generated during the drying process, thus improving drying efficiency.
[0004] The above solution intermittently aligns the air outlet with the steam discharge port by rotating the drying cylinder, which makes it impossible to continuously discharge steam into the drying cylinder and affects the efficiency of steam discharge into the drying cylinder. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a drying device for optical cable production, which has the advantages of continuously discharging steam from the drying drum while it is rotating, avoiding intermittent steam discharge, and improving the efficiency of steam discharge from the drying drum. This solves the problem that the intermittent alignment of the air outlet and the steam discharge port during the rotation of the drying drum makes it impossible to continuously discharge steam from the drying drum, thus affecting the efficiency of steam discharge from the drying drum.
[0006] To achieve the aforementioned goal of continuously venting steam from the drying drum during rotational drying, avoiding intermittent steam venting, and improving the efficiency of steam venting from the drying drum, this application provides the following technical solution: A drying device for optical cable production, comprising a base, a drying drum mounted on top of the base, a drying module disposed inside the drying drum, the drying drum being composed of multiple sections, exhaust ports being provided between the multiple sections, multiple exhaust rings being rotatably disposed on the outer surface of the middle part of the drying drum, the positions of the multiple exhaust rings corresponding to the positions of the multiple exhaust ports, the exhaust rings covering the exhaust ports, exhaust holes being opened at the top of the multiple exhaust rings, exhaust branch pipes being provided at the exhaust holes at the top of the multiple exhaust rings, the bottoms of the multiple exhaust rings being fixed to the top of the base by fixing blocks, a belt being fitted onto the outer surface of one end of the drying drum by a pulley, the inner wall of the end of the belt away from the drying drum being fitted onto the outer surface of one end of the motor shaft by a pulley, and the bottom of the motor being fixed to the top of the base by fixing blocks.
[0007] The above scheme ensures that the exhaust port and exhaust ring between two adjacent sections of the drying drum remain connected during rotation, allowing steam inside the drying drum to be continuously discharged through the exhaust port and exhaust ring. This achieves continuous steam discharge from the drying drum during rotation, avoiding interruptions in steam discharge and improving the efficiency of steam discharge from the drying drum.
[0008] Furthermore, the two ends of the drying cylinder are rotatably mounted inside the inner wall of one end of two bearing supports, and the two bearing supports are mounted at both ends of the top of the base.
[0009] Through the above solution, the bearing support provides stable rotational support for the drying cylinder, enabling the drying cylinder to rotate smoothly around its own axis under the drive of the motor, thereby improving the stability of the drying cylinder during rotation.
[0010] Furthermore, four fixing plates are provided between two adjacent cylindrical sections, with each fixing plate having its two ends respectively located at one end of the two adjacent cylindrical sections. The four fixing plates are arranged in a circular array between the two adjacent cylindrical sections.
[0011] The above scheme allows adjacent drum sections to be connected by fixing plates, thus ensuring that each drum section rotates synchronously when the drying drum rotates. At the same time, the even distribution of the four fixing plates ensures the balance of forces between adjacent drum sections and allows for uniform exhaust from the exhaust port.
[0012] Furthermore, a support wheel is provided below the drying cylinder. The support wheel is rotatably mounted on the top of the support plate via a hinge frame. The two ends of the bottom of the support plate are mounted on the top of the base via support legs. The outer surface of the middle part of the support wheel is in contact with the outer surface of the middle part of the drying cylinder.
[0013] Through the above solution, the support wheel plays an auxiliary supporting role for the drying cylinder, reduces the bearing pressure on the bearing support, and prevents the middle part of the drying cylinder from sagging, further improving the stability of the drying cylinder rotation.
[0014] Furthermore, two support wheels are rotatably mounted at both ends of the top of the support plate via a hinge frame, with the two support wheels located on both sides below the drying cylinder.
[0015] With the above solution, two support wheels support the drying cylinder from both sides below, making the support more uniform and stable. This allows the drying cylinder to better bear the weight of the drying cylinder and its internal materials, further enhancing the stability of the drying cylinder during rotation and effectively preventing the drying cylinder from tilting or shaking due to uneven force.
[0016] Furthermore, a limiting ring is provided on the outer surface of one opposite end of each of the two adjacent cylindrical sections, and the outer surface of the opposite side of the two corresponding limiting rings is slidably connected to both sides of the inner wall of the corresponding exhaust ring.
[0017] Through the above scheme, the limiting ring plays a limiting role in the exhaust ring, preventing the exhaust ring from moving axially or shifting during the rotation of the drying cylinder, ensuring that the exhaust port and the exhaust hole on the exhaust ring always maintain the correct relative position, thereby ensuring that steam can be continuously and stably discharged through the exhaust port and the exhaust ring, improving the efficiency and reliability of steam discharge.
[0018] Furthermore, each of the plurality of exhaust branch pipes is provided with a connecting pipe at one end, and the plurality of connecting pipes are provided at the bottom of the manifold box, and the top of the manifold box is provided with an exhaust main pipe through an exhaust fan.
[0019] The above scheme allows the connecting pipe to collect the steam from multiple exhaust branch pipes into the manifold box, and then the exhaust fan will discharge the steam from the main exhaust pipe. This centralized discharge of steam facilitates steam treatment and purification, while also improving the efficiency of steam discharge and reducing the accumulation of steam inside the equipment.
[0020] Furthermore, a discharge gate is hinged to one end of the drying cylinder at the discharge port.
[0021] The above solution facilitates the loading and unloading of materials. Operators can open the loading door to put the optical cable to be dried into the drying cylinder, and then open the loading door to take out the optical cable after drying.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This drying equipment for optical cable production ensures that the exhaust port and exhaust ring between two adjacent sections of the drying cylinder remain connected during rotation. This allows the steam inside the drying cylinder to be continuously discharged through the exhaust port and exhaust ring, achieving continuous steam discharge from the drying cylinder while it is rotating and drying. This avoids interruptions in steam discharge and improves the efficiency of steam discharge from the drying cylinder. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0026] Please see Figure 1 , Figure 3 and Figure 5This embodiment of a drying device for optical cable production includes a base 1, a drying cylinder 2 on top of the base 1, a drying module inside the drying cylinder 2, and the drying cylinder 2 being composed of multiple cylinder sections 201. Exhaust ports 202 are provided between the multiple cylinder sections 201. Multiple exhaust rings 3 are rotatably arranged on the outer surface of the middle part of the drying cylinder 2, with the positions of the multiple exhaust rings 3 corresponding to the positions of the multiple exhaust ports 202. The exhaust rings 3 cover the exhaust ports 202, and each of the multiple exhaust rings 3 has an exhaust hole 4 at its top. Each of the multiple exhaust rings 3 has an exhaust branch pipe 5 at its top exhaust hole 4. The bottom of each of the multiple exhaust rings 3 is fixed to the top of the base 1 by a fixing block. A belt 12 is fitted onto the outer surface of one end of the drying cylinder 2 via a pulley. The inner wall of the belt 12, away from the drying cylinder 2, is fitted onto the outer surface of one end of the motor shaft of a motor 13 via a pulley. The bottom of the motor 13 is fixed to the top of the base 1 by a fixing block. Please see Figure 1 , Figure 2 and Figure 3 The two ends of the drying cylinder 2 are rotatably mounted on the inner wall of one end of two bearing supports 11. The two bearing supports 11 are located at both ends of the top of the base 1. The bearing supports 11 provide stable rotational support for the drying cylinder 2, so that the drying cylinder 2 can rotate smoothly around its own axis under the drive of the motor 13, thereby improving the stability of the drying cylinder 2 when rotating.
[0027] Please see Figure 3 , Figure 5 and Figure 6 Four fixing plates 203 are provided between two adjacent cylindrical sections 201. The two ends of the fixing plates 203 are respectively provided at the opposite ends of the two adjacent cylindrical sections 201. The four fixing plates 203 are arranged in a ring array between the two adjacent cylindrical sections 201. The fixing plates 203 can connect the adjacent cylindrical sections 201, thereby ensuring that each cylindrical section 201 can rotate synchronously when the drying cylinder 2 rotates. At the same time, the uniform distribution of the four fixing plates 203 ensures the balance of the connection force between the two adjacent cylindrical sections 201, and can make the exhaust port 202 exhaust gas evenly.
[0028] Please see Figure 1 , Figure 2 and Figure 6 A support wheel 15 is provided below the drying cylinder 2. The support wheel 15 is rotatably mounted on the top of the support plate 14 via a hinge frame. The two ends of the bottom of the support plate 14 are mounted on the top of the base 1 via support legs. The outer surface of the middle part of the support wheel 15 contacts the outer surface of the middle part of the drying cylinder 2. The support wheel 15 plays an auxiliary support role for the drying cylinder 2, reduces the bearing pressure of the bearing support 11, and can prevent the middle part of the drying cylinder 2 from sagging, further improving the rotational stability of the drying cylinder 2.
[0029] Please see Figure 1, Figure 2 and Figure 6 The top of the support plate 14 has two support wheels 15 rotatably mounted at both ends via a hinge frame. The two support wheels 15 are located on both sides below the drying cylinder 2, and support the drying cylinder 2 from both sides below, making the support more uniform and stable. This allows the drying cylinder 2 to better bear the weight of the drying cylinder 2 and the materials inside it, further enhancing the stability of the drying cylinder 2 during rotation and effectively preventing the drying cylinder 2 from tilting or shaking due to uneven force.
[0030] Please see Figure 3 , Figure 5 and Figure 6 Each of the two adjacent cylindrical sections 201 has a limiting ring 10 on one of its opposite outer surfaces. The outer surfaces of the opposite sides of the two corresponding limiting rings 10 are slidably connected to the two sides of the inner wall of the corresponding exhaust ring 3. The limiting ring 10 limits the exhaust ring 3, preventing the exhaust ring 3 from moving axially or shifting during the rotation of the drying cylinder 2. This ensures that the exhaust port 202 and the exhaust hole 4 on the exhaust ring 3 always maintain the correct relative position, thereby ensuring that steam can be continuously and stably discharged through the exhaust port 202 and the exhaust ring 3, improving the efficiency and reliability of steam discharge.
[0031] Please see Figure 1 , Figure 3 and Figure 4 Each of the multiple exhaust branch pipes 5 has a connecting pipe 6 at one end. The multiple connecting pipes 6 are located at the bottom of the manifold box 7. The top of the manifold box 7 is connected to the exhaust main pipe 8 via the exhaust fan 9. The connecting pipes 6 collect the steam from the multiple exhaust branch pipes 5 into the manifold box 7, and then the exhaust fan 9 discharges the steam from the exhaust main pipe 8. This allows for centralized discharge of steam, which is convenient for steam treatment and purification. It also improves the efficiency of steam discharge and reduces the accumulation of steam inside the equipment.
[0032] Please see Figure 1 , Figure 2 and Figure 3 A discharge door 16 is hinged at the discharge port at one end of the drying cylinder 2. The discharge door 16 facilitates the loading and unloading of materials. Operators can open the discharge door 16 to put the optical cable to be dried into the drying cylinder 2, and then open the discharge door 16 to take out the optical cable after drying.
[0033] In this embodiment, a drying device for optical cable production ensures that the exhaust port 202 between two adjacent sections 201 of the drying cylinder 2 remains connected to the exhaust ring 3 during rotation. This allows the steam inside the drying cylinder 2 to be continuously discharged through the exhaust port 202 in conjunction with the exhaust ring 3 during rotation, achieving continuous steam discharge from the drying cylinder 2 while it is rotating and drying, avoiding interruptions in steam discharge, and improving the efficiency of steam discharge from the drying cylinder 2.
[0034] The working principle of the above embodiment is as follows: By opening the discharge door 16, the operator can put the optical cable to be dried into the drying cylinder 2, and then close the discharge door 16 and start the drying module in the drying cylinder 2 to dry the optical cable. During the drying process, the motor 13 drives the drying cylinder 2 to rotate through the belt 12, and performs uniform drying on the optical cable in the drying cylinder 2. During the rotation of the drying cylinder 2, the outer surface of the middle part will rotate inside the exhaust ring 3. The steam generated during the drying in the drying cylinder 2 enters the exhaust ring 3 through the exhaust port 202 between adjacent cylinder sections 201. The steam is then discharged into the exhaust branch pipe 5 through the exhaust hole 4 at the top of the exhaust ring 3. The steam in multiple exhaust branch pipes 5 is collected into the manifold box 7 through the connecting pipe 6. Under the action of the exhaust fan 9, the steam is concentrated and discharged from the exhaust main pipe 8. When the drying cylinder 2 rotates, it will drive the support wheel 15 to rotate through contact with the support wheel 15, so that the support wheel 15 provides stable support for the drying cylinder 2.
