Technical Field

[0001] This application relates to the technical field of cable manufacturing, and particularly to a cable drying device. Background Art

[0002] In the cable manufacturing industry, during the manufacturing process of communication cable single-core wires, the production line speed can reach 800 to 1500 meters per minute. Since the single-core wire needs to pass through a water tank for cooling before passing through the tester, if the water remaining on the cable surface is not completely removed, it will cause an increase in the measurement error of the test instrument, thereby affecting the accuracy and stability of the test results. Such measurement errors may lead to incorrect adjustment of the equipment, thus affecting the technical parameters of the cable and ultimately the product quality.

[0003] Currently, the traditional method of drying cables mainly relies on vortex air pumps. However, it is difficult to completely blow dry the water on the cable surface by using a vortex air pump alone. The drying effect of the vortex air pump is limited. Especially in the case of high-speed production, the remaining moisture will significantly increase the measurement error. Therefore, the existing technology has obvious deficiencies in terms of drying efficiency and adaptability, and a new device that can improve the drying efficiency and adapt to different production speeds and cable specifications is needed.

[0004] Therefore, we need a cable drying device to solve the problem of being unable to completely remove the moisture on the cable surface and can completely remove the moisture on the cable surface. Summary of the Utility Model

[0007] In the above technical solution, in the embodiment of the present application, the air inlet is used to introduce air flow into the first inner cavity. The first inner cavity and the second inner cavity limit the cable and compress the air flow. The air flow flows at a high speed towards the cable, completely drying the moisture on the cable, solving the problem that the moisture on the cable surface cannot be completely removed, and enabling the complete removal of the moisture on the cable surface.

[0038] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by referring to examples. In the following description, many specific details are set forth to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and devices are not described in detail to avoid unnecessarily making these embodiments difficult to understand. Additionally, all embodiments can be used in combination with each other.

[0039] Embodiment 1: As Figures 1 - 4 shown, a cable 3 drying device includes:

[0040] A blowing head 1, the blowing head 1 includes a through first inner cavity 11, and the first inner cavity 11 is used for accommodating and conducting air flow;

[0041] The first inner cavity 11 extends along the axis of the air blowing head 1, and there is an interface longitudinally arranged on the air blowing head 1 that communicates with the first inner cavity 11;

[0042] The nozzle 2 is arranged at the left end of the air blowing head 1. There is a through second inner cavity 21 in the middle of the nozzle 2. The diameter of the second inner cavity 21 is the same as the minimum diameter of the first inner cavity 11, and the diameter of the second inner cavity 21 is larger than the diameter of the cable.

[0043] The adjusting device 4 is arranged between the air blowing head 1 and the nozzle 2. The adjusting device 4 is movably connected to the nozzle 2. Due to the setting of the adjusting device 4, the position of the nozzle 2 can be precisely adjusted according to the specification of the cable 3, widening or narrowing the distance between the air blowing head 1 and the nozzle 2, changing the space through which the air flow passes, so as to adapt to the drying requirements of different cables 3. Even when replacing cables 3 of different specifications, the best drying effect can be ensured through simple adjustment.

[0044] The air inlet device 7 is arranged at the interface; the air inlet guides the air flow into the first inner cavity 11, and the first inner cavity 11 and the second inner cavity 21 limit the cable and compress the air flow to flow towards the cable.

[0045] A tapered contraction part 12 is arranged at the right end of the first inner cavity 11. The tapered contraction part 12 gradually reduces the diameter of the first inner cavity 11. Through the design of the tapered contraction part 12, the air flow is effectively compressed and accelerated before entering the nozzle 2, ensuring that the air flow can act on the surface of the cable 3 at a high speed and high pressure, quickly removing the surface moisture and significantly improving the drying efficiency.

[0046] The nozzle 2 is arranged in a three-section manner. The outer diameter of the left section of the nozzle 2 is larger than the inner diameter of the adjusting device 4, so that the left section of the nozzle 2 limits the position of the adjusting device 4, preventing the first inner cavity 11 and the second inner cavity 21 of the air blowing head 1 from coming into complete contact and causing the air flow to be unable to pass through.

[0047] The middle section of the nozzle 2 is provided with an external thread. The middle section of the nozzle 2 is cooperatively connected with the first inner cavity 11 and the adjusting device 4. Through the setting of the thread, it is more convenient to adjust the position of the tapered contraction part 12 and the nozzle 2.

[0048] The outer diameter of the right section of the nozzle 2 is smaller than the inner diameter of the left end of the first inner cavity 11. The right end of the right section of the nozzle 2 has the same angle as the tapered contraction part 12. The outer diameter of the right section of the nozzle 2 being smaller than the inner diameter of the left end of the first inner cavity 11 allows more space for the air flow to be accommodated in the first inner cavity 11, and then the air flow is compressed by the tapered contraction part 12 to dry the water on the cable 3 faster and more efficiently.

[0049] The surfaces of the first inner cavity 11 and the second inner cavity 21 are provided with waterproof coatings. The interface is set as a pipe thread. A micro air pressure sensor 5 is arranged inside the second inner cavity 21. The waterproof coatings of the first inner cavity 11 and the second inner cavity 21 and the three-section design of the nozzle 2 effectively reduce the accumulation of moisture in the air flow and prevent the internal corrosion of the device. The setting of the micro air pressure sensor 5 further improves the intelligent level of the device. By monitoring and adjusting the air flow pressure in real time, the service life of the device is extended.

[0050] Embodiment 2: As Figures 5 - 7 shown, on the basis of Embodiment 1, this embodiment further improves a cable 3 drying device, including:

[0051] The external thread in the middle section of the nozzle 2 is specifically set as a double-thread. The internal thread of the adjusting device 4 is set to be left-handed, and the internal thread of the first inner cavity 11 is set to be right-handed.

[0052] A locking device 6 is arranged at the upper end of the blowing head 1. The locking device 6 includes:

[0053] A housing 61. The housing 61 is arranged at the upper end of the blowing head 1. The housing 61 is fixedly connected to the blowing head 1. A first sliding groove 611 is arranged at the upper end of the housing 61, and a second sliding groove 612 is arranged at the lower end of the housing 61; a ball 62. The ball 62 is arranged at the lower end of the housing 61. The ball 62 can roll relative to the housing 61; a locking bar 63. The locking bar 63 is arranged at the upper end of the ball 62. A locking portion 631 is arranged at the left end of the locking bar 63; a first spring 64. The first spring 64 is arranged between the first sliding groove 611 and the locking bar 63; a second spring 65. The second spring 65 is arranged between the second sliding groove 612 and the locking bar 63. The length of the first spring 64 is less than the length of the second spring 65.

[0054] Without the interference of external force factors, the second spring 65 pushes the locking bar 63 upward, and the first spring 64 pulls the locking bar 63 upward, making the locking bar 63 inclined. Pulling the locking bar 63 can make the first spring 64 and the second spring 65 move the locking bar 63 back and forth on the ball 62 through the first sliding groove 611 and the second sliding groove 612. When the locking bar 63 moves leftward to the left end of the adjusting device 4, the first spring 64 and the second spring 65 press the locking portion 631 downward, locking the adjusting device 4 and the blowing head 1 together. Since the internal threads in the first inner cavity 11 of the blowing head 1 and the internal thread of the adjusting device 4 have opposite helix directions, the blowing head 1 will not be displaced due to excessive air flow pressure, resulting in the moisture on the cable 3 not being dried.

[0055] When it is necessary to change the position of the blowing head 1, press the right end of the locking bar 63 downward to lift the locking portion 631, and pull the locking bar 63 backward until it completely disengages from the adjusting device 4.

[0056] Example 3: As Figure 8 shown, on the basis of Example 1, this example further improves the nozzle, including:

[0057] A pre-blowing part 22 is arranged at the right section position of the nozzle. The pre-blowing part 22 is arranged in a funnel shape, and the diameter of the upper end of the pre-blowing part 22 gradually becomes larger downward. When the air flow enters the first inner cavity 11, it will first enter the pre-blowing part 22. The pre-blowing part 22 will spread the air flow, initially spreading the area where too much moisture accumulates on the cable 3, making the moisture evenly distributed, and preventing too much moisture from accumulating in some parts of the cable 3, resulting in incomplete blowing.

[0058] Example 4: As Figures 1 - 8 shown, on the basis of Examples 1 - 3, this example also provides a method for using a cable drying device, including:

[0059] Ensure that the interface between the air inlet device 7 and the blowing head 1 is firmly connected by pipe threads, and check that the waterproof coatings of the first inner cavity 11 and the second inner cavity 21 are intact.

[0060] Before starting the equipment, adjust the position of the nozzle 2 through the adjusting device 4. Since the nozzle 2 is of a three-section design, the degree of air flow compression can be adjusted by adjusting the position of the middle section of the nozzle 2 and the conical contraction part 12.

[0061] Pass the cable 3 to be processed through the first inner cavity 11 of the blowing head 1 and make it pass through the second inner cavity 21 of the nozzle 2, ensuring that the cable 3 maintains a central position in the first inner cavity 11 and the second inner cavity 21 to ensure that the air flow is evenly distributed on the surface of the cable 3.

[0062] Adjust the locking device 6 on the blowing head 1. Ensure that the locking part 631 of the locking strip 63 is in firm contact with the adjusting device 4 to prevent the displacement of the blowing head 1 due to air flow pressure during operation.

[0063] Introduce air flow into the first inner cavity 11 through the air inlet device 7. When the air flow enters, it will first enter the pre-blowing part 22. The pre-blowing part 22 spreads the air flow, so that the excessive moisture accumulated on the surface of the cable 3 is initially dispersed and evenly distributed, preventing excessive local moisture accumulation on the surface of the cable 3, which affects the final drying effect.

[0064] When entering the formal drying operation, monitor the air flow pressure in real time through the micro air pressure sensor 5. If abnormal pressure is detected, adjust the position of the air inlet device 7 or the nozzle 2 in time to optimize the air flow effect.

[0065] After starting the air inlet device 7, the air flow will act on the surface of the cable 3 through the nozzle 2 in an accelerating state, and the moisture on the cable 3 will be quickly and efficiently dried.

[0066] Although the above description of the specific embodiments of the present application is provided for those skilled in the art to understand the present application, the present application is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present application defined and determined by the appended claims, all inventions and creations using the concept of the present application are within the scope of protection.
