[0027] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 4 As shown, this embodiment provides a drying device 100 to prevent oxidation of control cable conductors. It is placed between the annealing wheel and the wire storage wheel and is used to cool and dry the conductor formed after the metal rod is drawn.

[0029] A control cable conductor oxidation prevention drying device 100 includes a drying base 10, an air blowing assembly 20, a first drying mold 30, and a second drying mold 40. The drying base 10 has a wire-passing channel 11, which is arranged along a first direction X, parallel to the traction direction of the conductor. The wire-passing channel 11 allows the conductor to pass through, so that the conductor can be pulled through the drying base 10. Along the first direction X, the drying base 10 has an inlet side 1 and an outlet side 2 arranged opposite to each other. The conductor is pulled into the drying base 10 from the inlet side 1 and exits from the outlet side 2. The air blowing assembly 20 communicates with the wire-passing channel 11 and is configured to blow hot air towards a portion of the cable located within the wire-passing channel 11.

[0030] Both the first drying mold 30 and the second drying mold 40 contain polycrystalline components and possess high-temperature resistance. The first drying mold 30 is connected to the inlet side 1 of the drying base 10. The first drying mold 30 has a first air passage 301, the extension direction of which is parallel to the first direction X. The first air passage 301 allows conductors to pass through and is connected to the wire passage 11. The second drying mold 40 is connected to the outlet side 2 of the drying base 10. The second drying mold 40 has a second air passage 401, the extension direction of which is parallel to the first direction X. The second air passage 401 allows conductors to pass through and is connected to the wire passage 11.

[0031] The inner diameter of the second air channel 401 is smaller than the inner diameter of the first air channel 301, so that when the conductor passes through the second drying module 40, more air outside the second drying module 40 can enter the second drying module 40, and as the pulling speed of the conductor increases, more air outside the second drying module 40 enters the second drying module 40 faster and acts on the surface of the conductor. The above function is realized based on Bernoulli's principle. During the movement of the conductor being pulled, the air pressure around the conductor decreases to form a relatively low pressure area, thereby causing more air to flow from the air duct to the surface of the conductor, increasing the air flow, and thus cooling the annealed conductor. In a physical sense, when the flow rate of a fluid increases, its pressure decreases; conversely, when the flow rate decreases, the pressure increases. In addition, due to the flow limiting effect of the second air channel 401 formed in the second drying module 40, air forms a certain pressure in the second drying module 40, thereby increasing the flow of high-pressure air entering the drying seat 10 to meet the air flow demand caused by the increase in the pulling speed of the conductor, and achieving better drying effect.

[0032] In addition, the temperature of the air flow in the second drying module 40 is lower than the temperature of the hot air flow, so as to form a gradient temperature environment. The conductor is first acted on by the hot air flow with a higher temperature, and then acted on by the normal temperature air flow with a lower temperature, realizing step-by-step cooling of the conductor, and improving the annealing effect.

[0033] Thus, in the oxidation prevention and control cable conductor drying device 100, the conductor is first blown by the hot air flow of the air blowing assembly 20 when passing through the drying seat 10 during the pulling process, and then passes through the second drying module 40. The inner diameter of the second air channel 401 of the second drying module 40 is smaller than the inner diameter of the first air channel 301, so that when the conductor is pulled to pass through the second drying module 40, a large amount of air outside the second drying module 40 enters the second drying module 40 to blow the conductor with an air flow with a lower temperature than the hot air flow, thereby realizing step-by-step cooling of the conductor, avoiding the conductor from being easily reacted with oxygen in the air due to the high temperature of the conductor while ensuring good annealing effect of the conductor. In addition, when the conductor passes through the drying seat 10 and the second drying module 40, the air flow blows the liquid such as water stains remaining on the surface of the conductor away from the surface of the conductor, thereby avoiding the reaction between the conductor and the liquid such as water stains on the surface of the conductor, and further protecting the conductivity of the conductor after the annealing process.

[0034] For the convenience of subsequent reading, the first direction X, the second direction Z and the third direction Y are introduced to describe the embodiments of the present application. The first direction X, the second direction Z and the third direction Y can be three mutually non-parallel straight line directions in space; further, the first direction X, the second direction Z and the third direction Y can be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction X is taken as the X-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Z is taken as the Z-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction Y is taken as the Y-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0035] Please refer to Figures 1 to 4 In an embodiment, the blowing assembly 20 comprises a gas feeding member 21 and a heating member 24. The gas feeding member 21 is communicated with the threading channel 11 and is configured to deliver air flow to the threading channel 11. The heating member 24 is configured to heat the air flow delivered into the threading channel 11.

[0036] In the present embodiment, the blow-drying seat 10 is generally square in structure, and the threading channel 11 extends through the blow-drying seat 10 along the first direction X from one side to the other side. The blow-drying seat 10 is provided with an air inlet channel 12 extending inwardly from the end face of one end of the blow-drying seat 10 along the second direction Z to communicate with the threading channel 11. The end of the air inlet channel 12 away from the threading channel 11 is communicated with the gas feeding member 21. The gas feeding member 21 is a compression pump which can compress air and blow it uniformly to the surface of the conductor. The heating member 24 is located in the air inlet channel 12 and can heat the air delivered into the air inlet channel 12 by the gas feeding member 21. The heating member 24 can be a resistance heating device, for example, which uses the heat generated by the passage of electric current through a resistance to heat the gas.

[0037] It can be understood that in other embodiments, the heating member 24 can also be arranged in the threading channel 11 or at the communication between the threading channel 11 and the air inlet channel 12. The specific position is not limited in the present application, as long as the heating member 24 can heat the air entering the threading channel 11.

[0038] Further, the blowing assembly 20 further comprises a gas feeding pipeline 22 and an adjusting valve 23. One end of the gas feeding pipeline 22 is communicated with the gas feeding member 21, and the other end thereof is communicated with the end of the air inlet channel 12 away from the threading channel 11, so as to deliver the compressed air of the gas feeding member 21 into the air inlet channel 12 through the gas feeding pipeline 22. The adjusting valve 23 is arranged on the gas feeding pipeline 22 and is used to adjust the flow rate of the air flow delivered into the air inlet channel 12.

[0039] Please refer to Figures 1 to 4In an embodiment, the first air passage 301 is provided with a first temperature detecting member 33, and the second air passage 401 is provided with a second temperature detecting member 43. The first and second temperature detecting members 33 and 43 are temperature sensors, specifically thermocouples.

[0040] The oxidation-preventing and drying device 100 for control cable conductors further comprises a control assembly 50, which is signal connected with the first and second temperature detecting members 33 and 43, and is configured to receive a first temperature signal of the conductors in the first air passage 301 detected by the first temperature detecting member 33, and a second temperature signal of the conductors in the second air passage 401 detected by the second temperature detecting member 43.

[0041] The control assembly 50 is further signal connected with the regulating valve 23 and the heating member 24, and is configured to control the working states of the regulating valve 23 and the heating member 24 based on the first and second temperature signals. For example, when the first temperature signal is higher than a first temperature threshold, the control assembly 50 controls the heating member 24 to reduce the heating temperature, so as to avoid the temperature of the conductors in the threading passage 11 from being too high to cause oxidation reaction with oxygen in the air. When the second temperature signal is higher than a second temperature threshold, the control assembly 50 controls the regulating valve 23 to increase the flow rate of the compressed air, so as to increase the flow rate of the air flow blowing to the conductors, and thus increase the cooling speed of the conductors. In addition, when the second temperature signal is higher than the second temperature threshold, the control assembly 50 can also control the heating member 24 to reduce the heating temperature.

[0042] Please refer to Figures 2 to 5 In an embodiment, the oxidation-preventing and drying device 100 for control cable conductors further comprises a first mold base 60. In the first direction X, the first mold base 60 is connected to the incoming wire side 1 of the drying seat 10, and the first drying mold 30 is slidably connected to the first mold base 60. The first mold base 60 is provided with a first passage 61, and the two ends of the first passage 61 are respectively communicated with the first air passage 301 and the threading passage 11.

[0043] In the first direction X, the incoming wire side 1 of the drying seat 10 is provided with a first accommodating groove 13. The first mold base 60 is generally a circular truncated cone structure, and the first passage 61 extends through the surface of one side of the first mold base 60 to the surface of the other side in the first direction X, and the conductors can pass out of the first passage 61. The inner diameter of the first passage 61 is substantially the same as the inner diameter of the threading passage 11. The end face of one end of the first mold base 60 is provided with a first mounting portion 62, which is accommodated in the first accommodating groove 13, and a sealing structure such as a sealing ring can be arranged between the outer peripheral surface of the first mounting portion 62 and the inner wall of the first accommodating groove 13. The first mold base 60 and the drying seat 10 can be connected by fasteners such as screws.

[0044] The first drying die 30 comprises a first die part 31 and a first connecting part 32 integrally formed at one end of the first die part 31 in the first direction X. The first air passage 301 penetrates through the first die part 31, and the first connecting part 32 is a hollow cylindrical structure. The first connecting part 32 is sleeved on the outer circumferential surface of the first die holder 60, and the first connecting part 32 is threadedly connected to the outer circumferential surface of the first die holder 60. The position of the first drying die 30 relative to the first die holder 60 in the first direction X can be adjusted by rotating the first drying die 30, thereby realizing the length adjustment of the first drying die 30 and the first die holder 60 in the first direction X, so as to adjust the moving distance of the conductor after annealing from entering the first drying die 30 to entering the drying seat 10, so as to adjust the moving distance according to the temperature of the conductor after annealing, so as to avoid that the conductor with high temperature is suddenly affected by compressed air and rapidly cooled, which affects the performance of the conductor due to too fast temperature change.

[0045] In the embodiment, the control cable conductor oxidation drying device 100 further comprises a second die holder 80 connected to the side of the drying seat 10 away from the first die holder 60 in the first direction X, and the second drying die 40 is slidably connected to the second die holder 80. The second die holder 80 is provided with a second passage 81, and the two ends of the second passage 81 are communicated with the second air passage 401 and the threading passage 11 respectively.

[0046] In the first direction X, the outgoing side 2 of the drying seat 10 is provided with a second accommodating groove 14. The second die holder 80 is generally a circular table structure, and the second passage 81 extends from the surface of one side of the second die holder 80 to the surface of the other side thereof in the first direction X, and the conductor can pass out of the second passage 81. The inner diameter of the second passage 81 is substantially the same as the inner diameter of the threading passage 11. The end face of one end of the second die holder 80 is provided with a second mounting part 82, which is accommodated in the second accommodating groove 14, and a sealing structure such as a sealing ring can be arranged between the outer circumferential surface of the second mounting part 82 and the inner wall of the second accommodating groove 14. The second die holder 80 and the drying seat 10 can be connected by screws or other fasteners.

[0047] The second drying die 40 comprises a second die part 41 and a second connecting part 42 integrally formed at one end of the second die part 41 along the first direction X. The second air passage 401 penetrates through the second die part 41, and the second connecting part 42 is a hollow cylindrical structure. The second connecting part 42 is sleeved on the outer circumferential surface of the second die seat 80, and the second connecting part 42 is threadedly connected with the outer circumferential surface of the second die seat 80. The position of the second drying die 40 relative to the second die seat 80 along the first direction X can be adjusted by rotating the second drying die 40, so as to adjust the length of the second drying die 40 relative to the second die seat 80 along the first direction X, thereby adjusting the moving distance of the conductor from the drying seat 10 to the second drying die 40, so as to adjust the moving distance according to the temperature of the conductor detected by the second temperature detection member 43, and avoid that the conductor with high temperature directly leaves the second drying die 40 and reacts with oxygen in the air.

[0048] Please combine Figures 2 to 6 In an embodiment, the inner diameters of the first air passage 301 and the second air passage 401 can be dynamically adjusted.

[0049] In the embodiment, the first die part 31 comprises a base 311 and two sliding members 312. The two sliding members 312 are slidably connected to the base 311 along the third direction Y, and are spaced apart along the third direction Y to form the first air passage 301 together with the base 311. The sliding member 312 is approximately in the shape of "U", and the openings of the two sliding members 312 are oppositely arranged. The first driving mechanism 310 is arranged on the base 311. The first driving mechanism 310 can be a bidirectional linear reciprocating mechanism. The two sliding members 312 are respectively drivingly connected to the bidirectional linear reciprocating mechanism, so as to drive the two sliding members 312 to move close to or away from each other along the third direction Y, thereby adjusting the size of the first air passage 301. The bidirectional linear reciprocating mechanism can be a bidirectional air cylinder sliding table or a bidirectional lead screw sliding table.

[0050] In the embodiment, the structure of the second die part 41 and the adjustment mode of the second air passage 401 are the same as those of the first die part 31, and will not be described herein. The second driving mechanism 410 is arranged on the base 311 of the second die part 41. The second driving mechanism 410 can drive the two sliding members 312 of the second die part 41 to slide along the third direction Y, thereby adjusting the size of the second air passage 401. The second driving mechanism 410 and the first driving mechanism 310 are the same mechanism.

[0051] The control assembly 50 is signal connected with the first driving mechanism 310 and the second driving mechanism 410. When the control assembly 50 detects that the temperature of the conductor detected by the second temperature detecting member 43 is high or the traction speed of the traction device 3 moving the conductor is increased, the control assembly 50 controls the first driving mechanism 310 and the second driving mechanism 410 to act, so as to make the size difference between the first air passage 301 and the second air passage 401 larger, i.e. the size of the second air passage 401 is smaller than that of the first air passage 301, thereby increasing the flow rate of the air entering the second drying mold 40 and accelerating the cooling speed of the conductor.

[0052] In addition, the temperature of the conductor detected by the second temperature detecting member 43 has a first temperature threshold and a second temperature threshold, and the second temperature threshold is greater than the first temperature threshold. The traction speed of the traction device 3 moving the conductor has a first speed threshold and a second speed threshold, and the second speed threshold is greater than the first speed threshold. It is worth noting that the first temperature threshold, the second temperature threshold, the first speed threshold and the second speed threshold can be set according to actual needs.

[0053] When the control assembly 50 detects that the temperature of the conductor detected by the second temperature detecting member 43 is between the first temperature threshold and the second temperature threshold or the traction speed of the traction device 3 moving the conductor is between the first speed threshold and the second speed threshold, the control assembly 50 only controls the first driving mechanism 310 to act to make the size of the first air passage 301 larger or only controls the second driving mechanism 410 to act to make the size of the second air passage 401 smaller.

[0054] When the control assembly 50 detects that the temperature of the conductor detected by the second temperature detecting member 43 is greater than the second temperature threshold or the traction speed of the traction device 3 moving the conductor is greater than the second speed threshold, the control assembly 50 controls the first driving mechanism 310 to act to make the size of the first air passage 301 larger and controls the second driving mechanism 410 to act to make the size of the second air passage 401 larger, and the rate of the size of the first air passage 301 becoming larger is greater than the rate of the size of the second air passage 401 becoming larger, so as to make the size ratio of the second air passage 401 to the first air passage 301 smaller while ensuring the air flow of the first air passage 301 and the second air passage 401 becoming larger, thereby increasing the flow rate of the air flow through the second air passage 401 while increasing the air flow, and further more efficiently cooling.

[0055] When the control assembly 50 detects that the temperature of the conductor detected by the second temperature detecting member 43 is not high or the traction speed of the traction device 3 moving the conductor is reduced, the control assembly 50 controls the first driving mechanism 310 and the second driving mechanism 410 to act, so as to make the size difference between the first air passage 301 and the second air passage 401 smaller, thereby reducing the flow rate of the air entering the second drying mold 40.

[0056] In addition, the temperature of the conductor detected by the second temperature detecting member 43 has a third temperature threshold and a fourth temperature threshold, the fourth temperature threshold being less than the third temperature threshold, and the traction speed of the traction device 3 has a third speed threshold and a fourth speed threshold, the fourth speed threshold being less than the third speed threshold. It is worth noting that the third temperature threshold, the fourth temperature threshold, the third speed threshold and the fourth speed threshold can be set according to actual needs.

[0057] When the control assembly 50 detects that the temperature of the conductor detected by the second temperature detecting member 43 is between the fourth temperature threshold and the third temperature threshold or the traction speed of the traction device 3 moving the conductor is between the fourth speed threshold and the third speed threshold, the control assembly 50 only controls the first driving mechanism 310 to act to make the size of the first air passage 301 smaller or only controls the second driving mechanism 410 to act to make the size of the second air passage 401 larger.

[0058] When the control assembly 50 detects that the temperature of the conductor detected by the second temperature detecting member 43 is less than the fourth temperature threshold or the traction speed of the traction device 3 moving the conductor is less than the fourth speed threshold, the control assembly 50 controls the first driving mechanism 310 to act to make the size of the first air passage 301 smaller and controls the second driving mechanism 410 to act to make the size of the second air passage 401 smaller, and the rate of making the size of the first air passage 301 smaller is less than the rate of making the size of the second air passage 401 smaller, so that while ensuring the air flow rate of the first air passage 301 and the second air passage 401 becomes smaller, the ratio of the size of the second air passage 401 to the size of the first air passage 301 becomes larger, so that while reducing the air flow rate, the flow rate of the air flow through the second air passage 401 is also reduced, thereby reducing the rate of cooling.

[0059] Please combine Figure 4 and Figure 5 In an embodiment, the control cable conductor oxidation drying device 100 further comprises a first mold cover 70 and a second mold cover 90, and along the first direction X, the first mold cover 70 is connected to one end of the first drying mold 30 away from the first mold base 60, and the second mold cover 90 is connected to one end of the second drying mold 40 away from the second mold base 80.

[0060] The first mold cover 70 and the second mold cover 90 are both hollow cylindrical structures, and the first mold cover 70 is sleeved on the outer peripheral surface of the first mold part 31, and the second mold cover 90 is sleeved on the outer peripheral surface of the second mold part 41, so as to protect the first drying mold 30 and the second drying mold 40 by the first mold cover 70 and the second mold cover 90.

[0061] In the foregoing, specific embodiments of the application have been described with reference to the accompanying drawings. It will, however, be evident that various modifications and changes can be made thereto without departing from the broader spirit and scope of the application as set forth in the appended claims. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
