Description

Technical Field

[0001] This invention relates to the field of wire drying technology, specifically a tin-plated wire drying device with anti-oxidation function. Background Technology

[0002] Tin-plated wire generally refers to tin-plated copper wire, which means that a layer of tin is plated on the surface of copper wire. This makes the copper wire less prone to oxidation, improves its corrosion resistance, and extends the service life of the copper wire itself. However, the tin layer on the surface of tin-plated copper wire will also oxidize after long-term use. At this time, it is necessary to use acidic cleaning agents and water to clean off the oxide layer on the surface.

[0003] After the tin-plated wire is cleaned, the bundles of tin-plated wire are twisted together, and the water in the gaps between the wires is difficult to dry for a long time. Existing drying equipment requires heating the wire to a high temperature when drying the wire. However, the surface of the wire is wet, and being heated to a high temperature accelerates the oxidation of the tin plating layer during the drying process. Therefore, there is a need for a tin-plated wire drying device that can prevent oxidation. Summary of the Invention

[0007] Preferably, the drive assembly further includes a slide groove, a slide rod, and a slider.

The two slide grooves are respectively opened on the two sliding seats, and one end of the two slide rods is slidably connected to the inside of the two slide grooves.

[0008] Preferably, the water removal assembly includes a bracket and a threaded ring. The bracket is slidably connected to the base, and the threaded ring is fixedly connected to the bracket. The threaded ring is threadedly connected to the first screw.

[0009] Preferably, the dewatering assembly further includes a fixed rod, a sliding plate, a slip ring, and a sponge block. The sliding plate is slidably connected to the inner wall of the bend, the fixed rod is fixedly connected between the sliding plate and the threaded ring, the slip ring is slidably connected to the inner wall of the bend and is fixedly connected to the sliding plate, and the sponge block is fixedly connected to the slip ring.

[0010] Preferably, the wiping assembly includes a housing, a first rotating shaft, and a paddle. The housing is fixedly connected to the base, the first rotating shaft is rotatably connected to the inner wall of the housing, and the paddle is fixedly connected to the first rotating shaft. The interior of the housing and the interior of the curved tube are in communication.

[0011] Preferably, the wiping assembly further includes a second rotating shaft, a rotating wheel, and a sponge sleeve.

[0012] Preferably, the wiping assembly further includes a chain and gears, the chain being disposed between a first rotating shaft and a second rotating shaft, and the two gears being fixedly connected to the two second rotating shafts respectively, with the two gears meshing with each other.

[0013] This invention provides an improved tin-plating wire drying device with anti-oxidation properties, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, in this invention, by passing the wire through the drying tube and introducing inert helium gas into the drying tube, the wire can be prevented from contacting oxygen during drying, thereby preventing the tin layer on the surface of the wire from oxidizing rapidly due to high temperature during drying. When drying the wire, helium gas can form an airflow in the drying tube and be heated by the heating element, thus achieving high efficiency in drying the wire.

[0015] Secondly, in this invention, the motor enables the two sliding seats and pistons inside the box to reciprocate. The reciprocating motion of the two pistons and the one-way valve restrict the airflow direction, so that helium can form a one-way airflow in the drying tube. The helium airflow enters the box through the bend and connecting pipe, and is discharged into the drying tube from the exhaust pipe. At the same time, the motor enables the sponge block to move inside the bend, thereby absorbing the water droplets formed by the condensation of water vapor on the inner wall of the bend. After being squeezed by the inner wall of the bend, the sponge block squeezes out all the water and discharges it into the water storage tank.

[0016] Thirdly, in this invention, the circulating airflow formed by helium gas enables the blades to rotate. The rotation of the slurry, combined with the transmission of chains and gears, causes the two rotating wheels and the sponge sleeves to rotate. Since the wire needs to pass between the two sponge sleeves before entering the drying tube, the continuously rotating sponge sleeves can absorb large water droplets on the surface of the wire before it enters the drying tube, so that only a damp water film remains on the surface of the wire entering the drying tube. This can improve the drying efficiency of the wire and also avoid the generation of too much water vapor during the drying process. Attached Figure Description

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides an improved tin-plating wire drying device with anti-oxidation properties. The technical solution of this invention is as follows:

[0028] like Figures 1-6As shown, a tin-plated wire drying device with anti-oxidation function includes a drying tube 1 and a base 2. The drying tube 1 is fixedly connected to the base 2. A heating element 3 is fixedly connected to the inner wall of the drying tube 1. A ventilation assembly 5 is provided on the drying tube 1. The ventilation assembly 5 includes an inlet pipe 51, a bend pipe 52, a connecting pipe 53, a housing 54, an exhaust pipe 55, and a water storage tank 56. The inlet pipe 51 is fixedly connected to the drying tube 1. The bend pipe 52 and the exhaust pipe 55 are respectively fixedly connected to the two ends of the drying tube 1. The connecting pipe 53 is fixedly connected to the bend pipe 52. The housing 54 is fixedly connected between the connecting pipe 53 and the exhaust pipe 55. The water storage tank 56 is fixedly connected to the bottom of the bend pipe 52. Helium gas can be introduced into the drying tube 1 through the inlet pipe 51, and the helium gas flow heated by the heating element 3 dries the wire. This allows the wire to be dried without oxidation. The base 2 is equipped with a drive assembly 6, which includes a motor 61, a first screw 62, a second screw 63, a partition 64, a one-way valve 65, a sliding seat 66, and a piston 67. The motor 61 is fixedly connected to the base 2, the first screw 62 is fixedly connected to the output shaft of the motor 61, the second screw 63 is fixedly connected to the first screw 62, the partition 64 is fixedly connected to the inner wall of the housing 54, the one-way valve 65 is set on the partition 64 and the connecting pipe 53, the two sliding seats 66 are slidably connected between the partition 64 and the inner wall of the housing 54, and the two pistons 67 are respectively fixedly connected to the two sliding seats 66. The inside of the bent pipe 52 is equipped with a water removal assembly 7, and the base 2 is equipped with a guide assembly 4 and a wiping assembly 8.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, the guide assembly 4 includes a threaded sleeve 41, a vertical rod 42, a ring 43, and a sponge ring 44. Two threaded sleeves 41 are threadedly connected to both ends of the drying tube 1, two vertical rods 42 are fixedly connected to the base 2, two rings 43 are fixedly connected to the two vertical rods 42, and two sponge rings 44 are fixedly connected to the inside of the two rings 43. The tin-plated wire moves inside the drying tube 1 to complete the drying process. Before entering the drying tube 1, the tin-plated wire needs to pass through the ring 43 and sponge ring 44 at the front end of the drying tube 1. The tin-plated wire that passes through the drying tube 1 needs to pass through another ring 43 and sponge ring 44. The purpose of this is to straighten the wire at both ends of the drying tube 1 in advance and avoid bending and wear at the entrance of the threaded sleeve 41.

[0030] Furthermore, such as Figure 4As shown, the drive assembly 6 also includes a slide groove 68, a slide rod 69, and a slider 610. The slider 610 is slidably connected to the inner wall of the housing 54. The slider 610 is threadedly connected to the second screw 63. The two slide rods 69 are fixedly connected to the slider 610. The two slide grooves 68 are respectively opened on the two sliding seats 66. One end of the two slide rods 69 is slidably connected to the inside of the two slide grooves 68. The two sliding seats 66 and the slide grooves 68 are symmetrically arranged. Therefore, when the second screw 63 causes the slider 610 to reciprocate, the two slide rods 69 can cause the two sliding seats 66 and the piston 67 to move on the inner wall of the housing 54. The movement directions of the two sliding seats 66 are always opposite. Under the action of the movement of the two pistons 67, a circulating airflow can be formed between the housing 54 and the drying tube 1. The one-way valve 65 is used to limit the direction of the airflow during this process.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, the water removal component 7 includes a bracket 71 and a threaded ring 72. The bracket 71 is slidably connected to the base 2, and the threaded ring 72 is fixedly connected to the bracket 71. The threaded ring 72 is threadedly connected to the first screw 62.

[0032] Furthermore, such as Figure 5 As shown, the dewatering assembly 7 also includes a fixed rod 73, a sliding plate 74, a slip ring 75, and a sponge block 76. The sliding plate 74 is slidably connected to the inner wall of the bend 52. The fixed rod 73 is fixedly connected between the sliding plate 74 and the threaded ring 72. The slip ring 75 is slidably connected to the inner wall of the bend 52 and is fixedly connected to the sliding plate 74. The sponge block 76 is fixedly connected to the slip ring 75. The first screw 62 causes the bracket 71 and the threaded ring 72 to reciprocate, which in turn causes the fixed rod 73, the sliding plate 74, the slip ring 75, and the sponge block 76 to reciprocate, thus drying the wire. Water will evaporate during the process, so when the water vapor passes through the bend 52, it will condense into water droplets on the inner wall of the bend 52. The sponge block 76 inside the bend 52 can absorb the water vapor as it passes through. At the same time, the reciprocating movement of the sponge block 76 can wipe away and absorb the water droplets formed on the inner wall of the bend 52. During the movement, the sponge block 76 will come into contact with the bend of the bend 52, so that the sponge block 76 is squeezed by the inner wall of the bend 52, thereby squeezing out the water absorbed in the sponge block 76 and causing this water droplet to fall into the water storage tank 56 below the bend 52.

[0033] Furthermore, such as Figure 5 and Figure 6 As shown, the wiping assembly 8 includes a housing 81, a first rotating shaft 82, and a blade 83. The housing 81 is fixedly connected to the base 2, the first rotating shaft 82 is rotatably connected to the inner wall of the housing 81, and the blade 83 is fixedly connected to the first rotating shaft 82. The interior of the housing 81 is connected to the interior of the curved tube 52. When the helium gas flows in the curved tube 52, it will drive the blade 83 to rotate, thereby causing the first rotating shaft 82 to rotate.

[0034] Furthermore, such as Figure 1 , Figure 2 and Figure 6 As shown, the wiping assembly 8 also includes a second rotating shaft 84, a rotating wheel 86, and a sponge sleeve 87. The two second rotating shafts 84 are rotatably connected to the inner wall of the housing 81. The two rotating wheels 86 are respectively fixedly connected to the two second rotating shafts 84. The two sponge sleeves 87 are respectively fixedly connected to the two rotating wheels 86. When the tin-plating wire slowly moves through the drying tube 1, the tin-plating wire will pass between the two sponge sleeves 87 before entering the drying tube 1. The sponge sleeves 87 can remove large water droplets on the surface when they come into contact with the tin-plating wire, so that the tin-plating wire entering the drying tube 1 only has a small amount of damp water film on its surface, which helps the tin-plating wire to dry faster.

[0035] Furthermore, such as Figure 6 As shown, the wiping assembly 8 also includes a chain 85 and gears 88. The chain 85 is disposed between a first rotating shaft 82 and a second rotating shaft 84. The two gears 88 are respectively fixedly connected to the two second rotating shafts 84. The two gears 88 mesh with each other. When the first rotating shaft 82 rotates, one of the second rotating shafts 84 will rotate under the action of the chain 85. Under the action of the gears 88, the other wheel 86 will also rotate, thereby causing the two sponge sleeves 87 to rotate for wiping large water droplets on the surface of the wire.

[0036] Working principle: First, insert the end of the tin-plated wire into the sponge ring 44 on the ring 43, and then pass it between the two rotating wheels 86 and the sponge sleeve 87. Next, pass the wire through a threaded sleeve 41 on the drying tube 1, so that the wire passes through the entire drying tube 1. Then, pass the wire out from another threaded sleeve 41 at the other end of the drying tube 1. Then, pass the wire through another ring 43 and the sponge ring 44. At this point, the connection between the wire and the drying tube 1 is completed, and drying can be carried out.

[0037] During drying, the heating element 3 is energized and heated. Simultaneously, helium is prepared and introduced into the drying tube 1 through the inlet pipe 51. Since the diameter of the threaded sleeve 41 is similar to that of the tin-plated wire, only a very small amount of helium will leak out through the two threaded sleeves 41. After a period of helium introduction, air inside the drying tube 1 will be discharged from both ends, thus removing oxygen. At this time, the motor 61 is started, causing it to periodically rotate forward and backward. The rotation of the output shaft of the motor 61 drives the first screw 62 and the second screw 63 to rotate. The rotation of the second screw 63 causes the slider 610 to slide. The reciprocating sliding of the slider 610 causes the two sliding rods 69 connected to it to slide reciprocally. Since the two sliding rods 69 slide within the grooves 68 on the two sliding seats 66 respectively, and the two sliding... The moving seat 66 and the sliding groove 68 are symmetrically arranged, so the two sliding seats 66 will slide back and forth with the two pistons 67, and the sliding direction of the two pistons 67 will always be opposite. When the two pistons 67 slide, one of the pistons 67 generates negative pressure and air is introduced through the connecting pipe 53. The connecting pipe 53 is connected to the bent pipe 52, so the connecting pipe 53 will draw the helium in the drying tube 1 into the box 54. At the same time, the other piston 67 moves in the opposite direction to generate high pressure, which will discharge the helium in the box 54 through the exhaust pipe 55 and inject it into the drying tube 1. Therefore, after the motor 61 starts, the helium introduced into the drying tube 1 can form a circulating airflow through the box 54. The circulating helium airflow can dry the tin-plated wire passing through the drying tube 1. At the same time, the heating plate 3 can also heat the helium to improve the drying effect.

[0038] When the motor 61 drives the first screw 62 to rotate, the first screw 62 will cause the bracket 71 and the threaded ring 72 to move back and forth, which in turn causes the fixed rod 73 and the slider 74 to move back and forth. The slider 74 drives the slip ring 75 and the sponge block 76 to move back and forth. Since water will evaporate during the drying process of the wire, and helium will carry water vapor to participate in the airflow circulation, the water vapor will condense on the inner wall of the bend 52 when it passes through the bend 52 to form water droplets. The sponge block 76 inside the bend 52 can absorb the water in the water vapor when it passes through. At the same time, the reciprocating movement of the sponge block 76 can wipe and absorb the water droplets formed on the inner wall of the bend 52. During the movement, the sponge block 76 will contact the bend of the bend 52, so that the sponge block 76 is squeezed by the inner wall of the bend 52, thereby squeezing out the water absorbed in the sponge block 76 and causing this part of the water droplets to fall into the water storage tank 56 below the bend 52.

[0039] When the helium gas flows inside the bend 52, it drives the blade 83 to rotate. The rotation of the blade 83 causes the first shaft 82 to rotate. The rotation of the first shaft 82 drives the chain 85 to drive, thereby causing one of the second shafts 84 to rotate. Under the action of the gear 88, the other second shaft 84 will also rotate, thereby causing the wheel 86 and the sponge sleeve 87 to rotate. When the tin-plating wire slowly moves through the drying tube 1, the tin-plating wire will pass between the two sponge sleeves 87 before entering the drying tube 1. The sponge sleeves 87 can remove large water droplets on the surface of the tin-plating wire when they come into contact with it, so that the tin-plating wire entering the drying tube 1 only has a small amount of damp water film on its surface, which is conducive to the tin-plating wire drying faster.
