Description

Technical Field

[0001] The utility model relates to the technical field of test probes, in particular to a drying device for annealed copper wires. Background Technique

[0002] Copper wire strands are commonly used wire materials. They are drawn into thin copper wires step by step through copper rods, and then the thin copper wires are stranded into wire strands. In order to ensure that the copper wire strands have regular shapes and are not easily deformed after production, the copper wires are usually annealed during the copper wire production process to eliminate internal stress. To facilitate the cooling of the annealed copper wires and reduce the entry of oxygen into the annealing tube, the outlet of the annealing tube is usually immersed in water. After the copper wires are cooled by water, there is residual moisture on the surface. To prevent the copper wires from oxidizing, it is usually necessary to dry the surface of the copper wires, and usually a drying device is required to dry the annealed copper wires.

[0003] A cleaning device for annealed tin-plated copper wires described in the patent publication number CN210207767U is beneficial to scrape and clean the surface of the copper wires to remove impurities through the setting of the fixing plate and the cleaning brush bristles, ensuring full contact between the soldering flux and the surface of the copper wires.

[0004] However, when the above device dries the copper wires, it only dries them through the air-drying blower fan arranged above the copper wires. The flow range of the drying gas is relatively narrow, and the drying effect is limited, so that the surface of the copper wires cannot be completely dried, and the drying effect is generally predictable.

[0005] Therefore, the technical personnel in the field provide a drying device for annealed copper wires to solve the problems raised in the above background technique. Content of the Utility Model

[0033] As shown in the accompanying drawings of the specification Figures 1-9As shown in the figure, the utility model provides a drying device for annealed copper wire, which includes an outer blowing cylinder 1. An outer blowing cavity 2 is formed on the inner wall of the outer blowing cylinder 1. A plurality of outer blowing holes 3 communicating with the outer blowing cavity 2 are annularly arranged on the inner side wall of the outer blowing cylinder 1. A first nozzle 4 is fixedly arranged inside each outer blowing hole 3. The top end of the outer wall of the outer blowing cylinder 1 is provided with a first drying chamber 5. A first fan 6 is arranged on one side of the inner cavity of the first drying chamber 5. A first heating wire 7 is arranged in the middle of the inner cavity of the first drying chamber 5. The first drying chamber 5 is communicated with the outer blowing cavity 2 through a first air duct 8 arranged on its other side. A fixed seat 9 is fixedly arranged on one side of the outer blowing cylinder 1. A fixing plate 10 is arranged at the axis of the fixed seat 9. A plurality of fixing rods 11 connected with the fixed seat 9 are annularly arranged outside the fixing plate 10. A motor 12 is arranged at the axis of the surface of the fixing plate 10 close to the outer blowing cylinder 1. The motor 12 is fixedly connected with an inner blowing cylinder 14 through a driving shaft 13 at its top end. An inner blowing cavity 15 is formed on the inner wall of the inner blowing cylinder 14. A plurality of inner blowing holes 16 communicating with the inner blowing cavity 15 are annularly arranged on the outer wall of the inner blowing cylinder 14. A second nozzle 17 is fixedly arranged inside each inner blowing hole 16. The inner blowing cylinder 14 is made of light materials such as PC, which reduces the influence of its gravity on the fixing plate 10 and the motor 12, and can also meet its normal drying work. The end of the inner blowing cylinder 14 far from the driving shaft 13 is fixedly provided with a second drying chamber 18. A second fan 19 is arranged at the top end of the inner cavity of the second drying chamber 18 and a second heating wire 20 is arranged at the bottom end of its inner cavity. The second drying chamber 18 is communicated with the inner blowing cavity 15 through a second air duct 21 arranged on its one side. The working principles of the first drying chamber 5 and the second drying chamber 18 are similar. By turning on each fan and each heating wire, the heating wire generates hot gas. Through the opening of the fan, the hot gas is input into the inner cavities of the outer blowing cylinder 1 and the inner blowing cylinder 14 through each air duct, and is sprayed out through the first nozzle 4 and the second nozzle 17 to dry the copper wire. When drying the copper wire in the inner blowing cylinder 14, the motor 12 is turned on to control the driving shaft 13 to drive the inner blowing cylinder 14 to rotate circumferentially at the central axis position of the outer blowing cylinder 1. As Figures 1-5 shown, in this embodiment, the existing copper wire drying method is changed to blowing the copper wire by the inner and outer blowing cylinders 1. The annealed copper wire is extended between the outer blowing cylinder 1 and the inner blowing cylinder 14, and the inner blowing cylinder 14 is set to be rotatable. The drying gas is sprayed out from the two cylinders to approach and surround the copper wire for drying operation, which can expand the flow range of the drying gas and ensure that the device can dry the copper wire more comprehensively, thereby improving the overall drying range and drying effect of the device.

[0034] As a preferred solution of the utility model, preferably, as Figure 5As shown, a first filter screen 22 and a second filter screen 23 are sequentially arranged on the inner wall of the second air delivery pipe 21 from inside to outside. The mesh diameter specifications of the first filter screen 22 and the second filter screen 23 are different. Through the settings of the first filter screen 22 and the second filter screen 23, the drying gas flowing in the second air delivery pipe 21 can be double-filtered to filter out impurities and dust in the drying gas.

[0035] As a preferred embodiment of the present utility model, preferably, as Figure 8 shown, a plurality of guide rods 24 are circumferentially arranged on the surface of the inner air blowing cylinder 14 outside the drive shaft 13. A guide block 25 is fixedly arranged at the bottom end of each guide rod 24. A guide ring 26 is arranged outside the plate surface of the fixing plate 10. A guide groove 27 slidably connected to the guide block 25 is formed inside the guide ring 26. When the motor 12 drives the inner air blowing cylinder 14 to rotate, the guide rods 24 and the guide blocks 25 connected to the inner air blowing cylinder 14 rotate in the guide groove 27 of the guide ring 26, thereby providing guidance and maintaining stability for the rotation of the inner air blowing cylinder 14 and ensuring the rotation smoothness of the inner air blowing cylinder 14.

[0036] As a preferred embodiment of the present utility model, preferably, as Figure 4 shown, a third filter screen 28 is arranged in the inner cavity of the first drying chamber 5 on the side of the first heating wire 7 away from the first fan 6. Two groups of guiding blocks 29 are symmetrically arranged on the side of the inner cavity of the first drying chamber 5 away from the first fan 6. The first air delivery pipe 8 is arranged between the two groups of guiding blocks 29. Through the setting of the third filter screen 28, the heat drying gas generated by the heating wire in the first drying chamber 5 can be screened, and through the guiding blocks 29, the gas can be guided into the first air delivery pipe 8, so that it can flow more smoothly through the first air delivery pipe 8 to the outer air blowing cavity 2.

[0037] As a preferred embodiment of the present utility model, preferably, as Figure 9 shown, a heat insulation sleeve 30 is arranged on the outer wall of the outer air blowing cylinder 1. The inner surface of the heat insulation sleeve 30 is attached to the outer surface of the outer air blowing cylinder 1. The heat insulation sleeve 30 is made of heat insulation materials in the prior art (such as carbon fiber). As the outer air blowing cylinder 1 dries the copper wire, the temperature of its surface will also rise slightly. By sleeving the heat insulation sleeve 30, the staff does not need to directly contact the outer air blowing cylinder 1, improving its use safety performance, and it is also relatively convenient to disassemble the heat insulation sleeve 30.

[0038] As a preferred embodiment of the present utility model, preferably, as Figure 1 、 Figure 6As shown in the figure, two sets of fixing rings 31 are sleeved on the outer wall of the heat insulation sleeve 30. At the bottom end of each set of fixing rings 31, a support rod 32 is fixedly arranged. At the bottom end of the support rod 32, a support plate 33 is arranged. At the four corners of the support plate 33, support bolts 34 are movably arranged. The fixing rings 31 facilitate the connection and assembly between the support plate 33 and the outer air blowing cylinder 1. Then, by driving the support bolts 34 into the support plate 33, the outer air blowing cylinder 1 is fixedly installed at the installation station.

[0039] Working principle:

[0040] As shown in the attached drawings of the specification Figures 1-9 As shown, by driving the support bolts 34 into the support plate 33 in sequence, the outer air blowing cylinder 1 together with the equipment is installed at the corresponding working position. Then, the annealed copper wire is sequentially extended into the outer air blowing cylinder 1. At the same time, each fan and heating wire are turned on. The fans and heating wires in each drying chamber work to generate high-temperature drying gas, which is input into the air blowing cavities of each air blowing cylinder through the corresponding air delivery pipes. The drying gas entering the outer air blowing cavity 2 and the inner air blowing cavity 15 is ejected from the first nozzle 4 and the second nozzle 17 in sequence to perform high-temperature drying on the copper wire in the outer air blowing cylinder 1. During the drying process, the motor 12 is turned on. The motor 12 controls the circumferential rotation of the inner air blowing cylinder 14 through the drive shaft 13, so that the inner air blowing cylinder 14 together with the second nozzle 17 moves and ejects high-temperature drying gas at the same time. With the rotation of the inner air blowing cylinder 14 and the extension of the copper wire, the surface drying work of the copper wire is carried out in all directions.

[0041] The above are only the preferred embodiments of the present invention. The parts not described in the present invention can be implemented by adopting or referring to the existing technologies. Of course, the above description is not a limitation to the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present invention should also fall within the protection scope of the present invention.
