Description

Technical Field

[0001] The utility model relates to the technical field of copper wire processing, in particular to a high-efficiency drying device. Background Art

[0002] During the production and processing of copper wire, the copper wire undergoes annealing treatment, and its internal stress and prestress are well eliminated. After annealing, the residual temperature of the copper wire needs to be cooled by water. After water cooling, some moisture will remain on the surface of the copper wire. Through transmission and transfer, local oxidation will occur on the surface of the copper wire, affecting the performance of the copper wire. Therefore, the copper wire needs to be dried.

[0003] The existing copper wire drying operation usually directly transports the water-cooled copper wire into a drying box for heating and drying. However, since the copper wire has just passed through a water cooling tank, many water droplets adhere to its surface, making the surface humidity of the copper wire too high, affecting its drying efficiency.

[0004] Therefore, we propose a high-efficiency drying device to solve the above problems. Utility Model Content

[0028] See also Figure 2-3In order to reduce the moisture content of the copper wire before it enters the oven 4 and improve the drying efficiency, a dewatering structure 2 is provided, which includes a U-shaped frame 21, a pair of sponge cylinders 22 symmetrically installed in the U-shaped frame 21, and a pair of squeezing rollers 25, wherein the U-shaped frame 21 is fixed to the frame 1, the sponge cylinders 22 and the squeezing rollers 25 are both rotatable relative to the U-shaped frame 21, and the squeezing rollers 25 are symmetrically squeezed on the opposite sides of the two sponge cylinders 22, so that the sponge cylinders 22 are squeezed by the squeezing rollers 25 when rotating, and the sponge cylinders 22 can be squeezed out. The main gears 23 are symmetrically mounted on the outer side of the U-shaped frame 21, and the two main gears 23 are meshed and connected with each other. The main gears 23 are used to drive the sponge cylinder 22 to rotate, so that the two sponge cylinders 22 can rotate in opposite directions at the same speed. When the copper wire passes upward from the bottom of the sponge cylinder 22, its surface is in full contact with the sponge of the sponge cylinder 22, so as to achieve the purpose of wiping off the water drops, and one end of one of the main gears 23 away from the U-shaped frame 21 is coaxially connected with a bevel gear 231. The lower edge of gear one 231 is meshedly connected with bevel gear two 232, and the shaft of bevel gear two 232 is rotatably connected with the bottom end of U-shaped frame 21 to maintain its stability, and the lower end of bevel gear two 232 is coaxially connected with sub gear 233, and the edge of sub gear 233 is meshedly connected with driven gear 234, and the bottom of driven gear 234 is installed with knocking rod 236 through connecting rod 235, and the distance between connecting rod 235 and copper wire is less than the length of knocking rod 236, and when main gear 23 rotates, it can drive bevel gear Wheel 1 231 rotates, bevel gear 1 231 meshes with bevel gear 2 232 for transmission, bevel gear 232 drives sub gear 233 to rotate, sub gear 233 meshes with driven gear 234 for transmission, thereby driving knocking rod 236 to rotate and knock on the copper wire through connecting rod 235 to shake off most of the water droplets on the surface of the copper wire. In order to facilitate the driving of the entire structure, a motor 24 is installed at the central axis of one end of bevel gear 1 231 away from the main gear 23 through a coupling, and the main part of motor 24 is fixed on the frame 1.

[0029] See also Figure 2-3, considering that after the knocking rod 236 knocks the copper wire, the copper wire blocks the knocking rod 236, preventing it from continuing to rotate beyond the copper wire. To ensure the normal operation of each transmission part on the knocking rod 236 and enable it to rotate properly, a protruding tooth is provided in a quarter area of the outer circumference of the driven gear 234. The protruding tooth meshes with the sub-gear 233, and the area of the driven gear 234 without teeth is not in contact with the sub-gear 233, thus realizing intermittent meshing transmission with the sub-gear 233, so that it will not continuously drive the driven gear 234 to rotate. At the same time, the top of the connecting rod 235 is connected to a bracket 237. The top of the bracket 237 is fixed to the U-shaped frame 21. The bottom of the bracket 237 is in a U-shaped structure, and the connecting rod 235 passes through the U-shaped structure and is rotatably connected to the bracket 237. And a torsion spring 238 is sleeved around one end of the connecting rod 235 penetrating into the U-shaped structure of the bracket 237. When the connecting rod 235 drives the knocking rod 236 to rotate and knock the copper wire, it will also drive the torsion spring 238 to twist and be stressed. Thus, when the driven gear 234 is not meshed with the sub-gear 233, it can rotate back to its original position under the elastic action of the torsion spring 238 and wait for the sub-gear 233 to mesh with the driven gear 234 again, thereby realizing the reciprocating rotation of the knocking rod 236 and the effect of intermittently knocking the copper wire.

[0030] Please refer to Figure 2-3 , considering that the sponge cylinder 22 is in contact with and rubs against the copper wire for a long time, it is prone to wear and damage. To facilitate the replacement of the sponge cylinder 22, a central rod 221 penetrates through the inside of the sponge cylinder 22. The central rod 221 is coaxially fixed with the main gear 23 and is rotatably connected to the U-shaped frame 21. At the same time, a limiting piece 222 is sleeved outside one end of the central rod 221 away from the U-shaped frame 21, and a limiting piece 222 is fixed around one end of the central rod 221 close to the U-shaped frame 21. A nut 223 is screwed onto the end of the central rod 221, so that the nut 223 is tightened. At this time, the sponge cylinder 22 is clamped between the two limiting pieces 222, making it fixed relative to the central rod 221, and thus facilitating its rotation following the central rod 221.

[0031] Please refer to Figure 2-3 , to prevent the liquid water generated when the extrusion roller 25 squeezes the sponge cylinder 22 from dripping back onto the copper wire again, a water collecting box 26 is provided at the bottom of the extrusion roller 25. The water collecting box 26 completely covers the bottom of the extrusion roller 25 and partially covers the bottom of the sponge cylinder 22. The two ends of the extrusion roller 25 are rotatably connected to the water collecting box 26, so that the extruded liquid water can be effectively collected by the water collecting box 26. At the same time, a drain port 261 is connected to the bottom of the water collecting box 26. The drain port 261 protrudes from the bottom surface of the water collecting box 26, facilitating the connection of a drainage pipe for drainage.

[0032] Please refer to Figure 2-3In order to facilitate the adjustment of the extrusion force of the extrusion roller 25, a water collecting box 26 is connected to the U-shaped frame 21 through a screw 27 and a limit rod 28, wherein the screw 27 and the limit rod 28 both penetrate the U-shaped frame 21, and the screw 27 is threadedly connected to the U-shaped frame 21, and the limit rod 28 is slidingly connected to the U-shaped frame 21, and at the same time, the end of the screw 27 is rotatably connected to the water collecting box 26, so that when the screw 27 is turned, the water collecting box 26 can be driven to move, and its distance relative to the sponge tube 22 can be adjusted, thereby adjusting the extrusion strength between the extrusion roller 25 and the sponge tube 22.

[0033] See also Figure 4 In order to improve the drying efficiency, a hollow inner cylinder 31 is provided in the preheating cylinder 3, and an electric heating wire 32 is spirally wound on the outer circumferential side wall of the hollow inner cylinder 31. By applying a heat-insulating paint on the inner wall of the preheating cylinder 3, its thermal conductivity is reduced, so that when the electric heating wire 32 is working, it mainly dissipates heat into the hollow inner cylinder 31 to heat the copper wire, thereby improving the efficiency of evaporation of water on the surface of the copper wire, so that the humidity is lower when it enters the drying oven 4.
