Description

Technical Field

[0001] The invention relates to the technical field of copper wire processing, in particular to an improved automatic cooling and drying line for tinned copper wires. Background Art

[0002] Tinned copper wire is copper wire coated with a thin layer of metallic tin. Tinned copper wire is relatively soft and has excellent electrical conductivity. Compared to bare copper wire, it offers enhanced corrosion and oxidation resistance, significantly extending the service life of low-voltage cables. In the production process, the copper wire is typically cooled after being hot-dip tinned in a tin furnace. This allows the tin coating to solidify quickly and adhere firmly to the surface.

[0003] At present, there are two cooling treatment methods commonly used in tinned copper wire processing lines. One is immersion cooling, which is to immerse the tinned copper wire in a cooling water tank for cooling. This method has a significant cooling effect, but various impurities are easily retained in the water tank, which can easily pollute the tinned layer and is not conducive to the continuous production of the product. Another commonly used cooling treatment method is spray cooling, which is to spray coolant through a nozzle to cool the copper wire. In this method, the coolant flows continuously, so no impurities will remain. However, the spraying process often cannot make the copper wire fully contact with the coolant, and the cooling effect is not high. Summary of the Invention

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] See also Figure 1 、 Figure 2 and Figure 3As shown, the present invention is an improved tinned copper wire automatic cooling and drying line, comprising a cooling chamber 1, a drying chamber 2 and a winding box 3 arranged in sequence along the copper wire conveying direction, the cooling chamber 1 is connected to the drying chamber 2, the drying chamber 2 is connected to the winding box 3, a box cover 4 is rotatably installed on the top of the winding box 3, a cooling mechanism 5 is provided inside the cooling chamber 1, a wire inlet hole 101 for the copper wire to pass through is provided at one end of the cooling chamber 1, a wire sleeve 104 is provided on the edge of the wire inlet hole 101, and a side wall of the cooling chamber 1 is extended to provide a side edge. The outer shell 102 has a driving motor 103 fixedly arranged on the side outer shell 102, a driving wheel 105 is rotatably installed in the side outer shell 102, the output end of the driving motor 103 is connected to the driving wheel 105, a drying mechanism 6 is provided in the drying chamber 2, an outlet fan row 7 is fixedly arranged at the bottom of the winding box 3, a winding motor 301 is fixedly arranged on the outside of the winding box 3, a winding roller 8 is rotatably installed in the winding box 3, the output end of the winding motor 301 is connected to the winding roller 8, and the air outlet of the outlet fan row 7 is facing the winding roller 8.

[0028] Specifically, by setting up a cooling chamber 1, a drying chamber 2 and a winding box 3, the tinned copper wire enters the cooling chamber 1 from the wire inlet hole 101, is guided by the wire sleeve 104, passes through the cooling mechanism 5 and begins to cool, and the cooled tinned copper wire enters the drying chamber 2, and then the drying mechanism 6 heats and dries the copper wire. At the same time, the winding motor 301 drives the winding roller 8 to rotate, thereby winding the dried copper wire, thereby realizing the automated processing process of cooling, drying and winding the tinned copper wire.

[0029] like Figure 3 、 Figure 4 and Figure 5 As shown, the cooling mechanism 5 includes a rotating wheel 501 with a through hole in the center, and support rollers 106 are rotatably installed at the four corners of the inner wall of the cooling chamber 1. The rotating wheel 501 is rotatably installed between the support rollers 106, and the driving wheel 105 is against the circumferential outer wall of the rotating wheel 501. Rectangular brackets 502 are extended from both ends of the rotating wheel 501. Pairs of horizontal contact rollers 503 and vertical contact rollers 504 are rotatably installed in the two sets of rectangular brackets 502. The horizontal contact rollers The structure of 503 is the same as that of the longitudinal contact roller 504, and the transverse contact roller 503 and the longitudinal contact roller 504 are perpendicular to each other to form a gap in the center for the copper wire to pass through. The transverse contact roller 503 is installed in the rectangular bracket 502 for sliding up and down and keeps moving toward each other. The transverse contact roller 503 is fixedly sleeved on the outside of the roller shaft 5031. A hollow cavity 5032 is provided inside the roller shaft 5031 along the axis, and liquid seepage holes 5033 are evenly arranged and provided on the outer wall of the hollow cavity 5032.

[0030] Specifically, by setting up the cooling mechanism 5, the coolant will be introduced into the hollow cavity 5032, and absorbed and soaked by the transverse contact roller 503 and the longitudinal contact roller 504 through the seepage hole 5033. Since the transverse contact roller 503 and the longitudinal contact roller 504 are perpendicular to each other, the copper wire passes through the gap between the two sets of contact rollers. During this process, the transverse contact roller 503 and the longitudinal contact roller 504 soaked in the coolant will simultaneously come into contact with the surface of the copper wire. At the same time, the driving motor 103 drives the driving wheel 105 to rotate, and the driving wheel 105 drives the rotating wheel 501 to rotate, thereby performing a full and comprehensive contact cooling process on the copper wire, effectively improving the cooling effect on the copper wire.

[0031] like Figure 3 As shown, both ends of the rectangular bracket 502 are penetrated by a limiting sliding groove 5021 , a limiting slider 5022 is slidably installed in the limiting sliding groove 5021 , and both ends of the roller shaft 5031 rotate and penetrate the limiting slider 5022 .

[0032] like Figure 5 As shown, a power motor 511 is fixedly installed in the center of the side wall of the rectangular bracket 502, and the output end of the power motor 511 is fixedly connected to an adjustment plate 512. Both ends of the adjustment plate 512 are rotatably matched with one end of the connecting rod 513, and the other end of the connecting rod 513 is rotatably matched with the corresponding limit slider 5022.

[0033] Specifically, by providing a limit slider 5022 and an adjustment plate 512, when the power motor 511 is in operation, it will drive the adjustment plate 512 to rotate. The adjustment plate 512 will drive the limit sliders 5022 at both ends to move toward each other through the connecting rod 513, thereby adjusting the gap between the transverse contact rollers 503 (or longitudinal contact rollers 504). This ensures that when the galvanized copper wire passes through the gap between the contact rollers, the contact rollers can fully contact and abut the surface of the copper wire to ensure a cooling effect. At the same time, the gap adjustment process of the contact rollers can meet the cooling requirements of copper wires of different diameters, and has a wide range of applications. During the gap adjustment process, the limit slider 5022 always slides along the limit slot 5021, thereby ensuring the stability of the linear displacement process.

[0034] like Figure 4 and Figure 5 As shown, a liquid storage tank 505 and a liquid collecting tank 507 are fixedly provided at both ends of the rectangular bracket 502, the liquid storage tank 505 is connected to one end of a liquid inlet pipe 508, a condenser 506 is provided on the liquid inlet pipe 508, the other end of the liquid inlet pipe 508 is connected to one end of the upper transverse contact roller 503, the other end of the upper transverse contact roller 503 is connected to one end of a liquid guide tube 509, the other end of the liquid guide tube 509 is connected to one end of the lower transverse contact roller 503, and the other end of the lower transverse contact roller 503 is connected to the liquid collecting tank 507 through a liquid outlet pipe 510.

[0035] Specifically, the water source stored in the liquid storage tank 505 is pumped into the liquid inlet pipe 508, and the water flow is cooled by the condenser 506 to form a coolant. The coolant is further introduced into the hollow cavity 5032 inside the roller shaft 5031 and seeps out through the seepage hole 5033. The transverse contact roller 503 begins to absorb the coolant, and then the coolant continues to flow through the liquid guide tube 509 to the transverse contact roller 503 below, so that the transverse contact roller 503 is evenly soaked. Finally, the remaining coolant will flow through the liquid outlet pipe 510 to the liquid collection tank 507 for collection, thereby realizing the entire pipeline circulation process of the coolant.

[0036] like Figure 6 As shown, the drying mechanism 6 includes a drying cavity tube 601, the axial direction of the drying cavity tube 601 is aligned with the conveying direction of the copper wire, the drying cavity tube 601 is fixedly connected to the drying chamber 2 through a fixing frame 602, a heater 603 is fixedly provided at the bottom of the drying chamber 2, a fan 605 is fixedly provided on the outer wall of the drying chamber 2, the fan 605 is connected to the input end of the heater 603 through an air inlet pipe 606, the output end of the heater 603 is connected to one end of the drying cavity tube 601 through a ventilation pipe 604, and the other end of the drying cavity tube 601 is connected to the fan exhaust 7 through an air outlet pipe 607.

[0037] As shown in Figure 7, an extension shell 6041 is fixedly provided on the outside of the ventilation pipe 604, and an impeller 6043 is provided in the extension shell 6041. The impeller 6043 rotates with the extension shell 6041 through a synchronization shaft 6042. Both ends of the synchronization shaft 6042 pass through the extension shell 6041 and extend to the outside. Two groups of paired traction rollers 9 are provided at one end of the drying cavity tube 601 close to the cooling chamber 1. The traction rollers 9 are rotatably installed on the mounting bracket 901. The mounting bracket 901 is fixedly connected to the drying chamber 2. Both ends of the synchronization shaft 6042 are respectively connected to the two groups of traction rollers 9 through transmission belts 6044.

[0038] Specifically, by setting up a drying mechanism 6, the fan 605 draws air into the heater 603 through the air inlet pipe 606. After being heated by the heater 603, the hot air flow flows into the drying cavity tube 601 through the ventilation pipe 604, so that the drying cavity tube 601 is filled with hot air flow to evenly and fully dry the copper wire. At the same time, when the hot air flow flows in the ventilation pipe 604, the impeller 6043 starts to drive the synchronous shaft 6042 to rotate, and the two ends of the synchronous shaft 6042 start to drive the traction roller 9 to rotate through the transmission belt 6044, so that the copper wire is dried and pulled forward. The heated hot air flow is introduced into the outlet fan row 7 through the outlet fan row 607, and the outlet fan row 7 is used to further dry the copper wire being wound up, so as to improve the drying effect of the copper wire.

[0039] like Figure 7As shown, rubber sealing sleeves 6011 are provided at both ends of the drying cavity tube 601 , and a temperature sensor 6012 is provided at the top of the drying cavity tube 601 . The temperature sensor 6012 is in communication connection with the heater 603 .

[0040] Specifically, when the tinned copper wire passes through the rubber sealing sleeves 6011 at both ends, the rubber sealing sleeves 6011 are in contact with the surface of the copper wire, thereby ensuring the sealing inside the drying cavity tube 601, so that the hot air flow can fill the internal space of the drying cavity tube 601; the temperature sensor 6012 can monitor the drying temperature inside the drying cavity tube 601 in real time. When the temperature is too high, the heater 603 will reduce the heating power in time to avoid the influence of the high drying temperature on the tinned copper wire.

[0041] The working principle of the present invention is as follows: Figure 1-Figure 7 As shown, during use, the tinned copper wire enters the cooling chamber 1 through the wire inlet 101, is guided by the wire sleeve 104, and then passes through the cooling mechanism 5 to begin cooling. Water stored in the liquid storage tank 505 is pumped into the liquid inlet pipe 508, where it is cooled by the condenser 506 to form a coolant. The coolant is then introduced into the hollow cavity 5032 within the roller shaft 5031 and seeps out through the seepage holes 5033. The transverse contact rollers 503 and the longitudinal contact rollers 504 begin to absorb the coolant. Because the transverse contact rollers 503 and the longitudinal contact rollers 504 are perpendicular to each other, the copper wire passes through the gap between the two sets of contact rollers. During this process, the transverse contact rollers 503 and the longitudinal contact rollers 504, soaked with coolant, simultaneously come into contact with the surface of the copper wire. Simultaneously, the drive motor 103 drives the drive wheel 105 to rotate, which in turn drives the rotating wheel 501 to rotate, thereby providing a comprehensive contact cooling process for the copper wire, effectively improving the cooling effect on the copper wire. The cooled tinned copper wire is further transported forward into the drying chamber 2, where it is heated and dried by the drying mechanism 6. The fan 605 draws air into the heater 603 through the air inlet pipe 606. After being heated by the heater 603, the hot air flows into the drying cavity 601 through the ventilation pipe 604, filling the drying cavity 601 with hot air to evenly and fully dry the copper wire. At the same time, when the hot air flows in the ventilation pipe 604, the impeller 6043 starts to drive the synchronous shaft 6042 to rotate, and the two ends of the synchronous shaft 6042 start to drive the traction roller 9 to rotate through the transmission belt 6044, so that the copper wire is pulled forward while being dried. The heated hot air is introduced into the outlet fan row 7 through the air outlet pipe 607, and the outlet fan row 7 is used to further dry the copper wire being wound to improve the drying effect of the copper wire. At the same time, the winding motor 301 drives the winding roller 8 to rotate, thereby winding the dried copper wire, thereby realizing the automated processing process of cooling, drying and winding the tinned copper wire.

[0042] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
