Description

Technical Field

[0001] This utility model relates to the field of bare copper wire preprocessing technology, and in particular to a copper wire dryer for bare copper wire preprocessing. Background Technology

[0002] Bare copper wire is widely used as a basic conductive material in many industries such as electronics and electrical engineering. During the pre-processing of bare copper wire, such as drawing, pickling, and washing, residual moisture remains on its surface. If this moisture is not removed promptly, it will seriously affect the subsequent processing and use of the bare copper wire. For example, during surface treatment processes such as tin plating and silver plating, the presence of moisture can lead to uneven plating, defects such as bubbles and pitting, thereby reducing the conductivity and corrosion resistance of the bare copper wire and affecting product quality.

[0003] Currently, the drying process for bare copper wires typically involves natural air drying, simple heating boxes, or open-air hot air devices. These traditional methods suffer from uneven heating, low efficiency, and inaccurate temperature control. They are not only time-consuming but also prone to causing localized overheating, oxidation, discoloration, or surface damage to the copper wires, affecting product quality and consistency. Furthermore, most existing equipment lacks tension control and guiding protection during the copper wire operation, which can easily lead to copper wire entanglement and knotting, affecting production continuity and operational safety.

[0004] Therefore, it is necessary to design a copper wire drying device with a reasonable structure, precise temperature control, stable operation, and tension adjustment and guiding functions to improve drying efficiency and bare copper wire processing quality, and meet the demand for efficient and high-quality pretreatment equipment in modern wire and cable production. Utility Model Content

[0005] To overcome the shortcomings of uneven heating and low efficiency that are often found in drying bare copper wires using natural air drying, simple heating boxes, or open hot air devices, this utility model provides a copper wire dryer for pre-processing bare copper wires.

[0006] A copper wire dryer for pre-processing bare copper wire includes an outer frame, a support frame, a base plate, heating tubes, a first support column, a first motor, a first rotating cylinder, second fixed columns, a handle, a fixing block, a spring, a second rotating cylinder, and a controller. The support frame is fixedly connected to the bottom of the outer frame. Feed troughs and discharge troughs are provided on both sides of the outer frame. The base plate is fixedly connected to the top of the support frame, located inside the outer frame. A row of heating tubes is fixedly connected inside the base plate. The first support column is fixedly connected to the left side of the support frame. The first motor is fixedly connected inside the first support column. The first rotating cylinder is fixedly connected to the output shaft of the first motor. Second fixed columns are symmetrically fixedly connected to the front and rear of the base plate. Two fixed columns are rotatably connected to another first rotating cylinder. The outer frame is symmetrically connected to two handles that slide down into the outer frame and correspond to the positions of the two first rotating cylinders. Fixed blocks are fixedly connected to the two handles symmetrically front and back. Springs are wound around the handles, with one end of the spring fixedly connected to the fixed block and the other end fixedly connected to the outer frame. A second rotating cylinder is rotatably connected between the two fixed blocks. The second rotating cylinder is located above the first rotating cylinder and there is a certain gap between them, which corresponds to the position of the discharge chute. A controller is fixedly connected to the outer wall of the first support column. The first motor and the heating tube are electrically connected to the controller.

[0007] Optionally, it also includes a first fixed column, a sponge roller, a pulley and a rubber belt. The first fixed column is fixedly connected to the left side of the base plate. The upper and middle parts of the two first fixed columns are rotatably connected to the sponge roller. There is a certain gap between the two sponge rollers, and the gap corresponds to the position of the feed chute. The front end of the sponge roller located in the middle of the first fixed column is fixedly connected to the pulley. Another pulley is fixedly connected to the output shaft of the first motor. A rubber belt is sleeved between the two pulleys.

[0008] Optionally, it also includes a second support column, a second motor, a winding shaft, and support blocks. The second support column is fixedly connected to the right side of the support frame, the second motor is fixedly connected to the top of the second support column, the winding shaft is fixedly connected to the output shaft of the second motor, support blocks are fixedly connected symmetrically to the front and rear of the support frame, the winding shaft is located between the two support blocks and is rotatably connected to the support blocks, and the second motor is electrically connected to the controller.

[0009] Optionally, it also includes a fan, with the fan fixedly connected to the top of the outer frame, and several ventilation slots opened on the top of the outer frame.

[0010] Optionally, it also includes a guide plate, which is fixedly connected to the feed chute.

[0011] Optionally, both the first rotating cylinder and the second rotating cylinder are fitted with anti-slip sleeves.

[0012] The beneficial effects are: 1. The sponge roller plays an important pre-treatment role in this utility model. It can not only perform preliminary wiping on the surface of the bare copper wire to effectively remove some moisture and impurities, but also transport the bare copper wire to the next position. The heating tube emits uniform heat flow through the through holes on the bottom plate, which can achieve efficient and uniform heating and drying of the bare copper wire. This design allows all parts of the bare copper wire to fully contact the heat, avoiding local overheating or overcooling.

[0013] 2. This utility model, through the cooperation of a fan and ventilation slots, accelerates airflow, promptly removes evaporated moisture, and maintains a dry drying environment. In actual operation, especially in humid environments such as the plum rain season in southern China, this dehumidification mechanism effectively prevents moisture accumulation in the drying chamber, avoids the bare copper wires from becoming damp again, and ensures the longevity of the drying effect.

[0014] 3. This invention, through the inclusion of a winding device, allows the rotating winding shaft to systematically wind and collect the dried bare copper wire. This function enables the bare copper wire to be quickly and neatly organized after drying, facilitating subsequent storage and transportation. In large-scale production, the winding shaft's efficient winding capability significantly improves production efficiency and reduces the workload and time costs associated with manual handling.

Detailed Implementation

[0022] Example: A copper wire dryer for pre-processing bare copper wire, such as... Figures 1-6 As shown, the device includes an outer frame 1, a support frame 2, a base plate 3, heating tubes 4, a first support column 7, a first motor 8, a first rotating cylinder 9, a second fixed column 12, a handle 13, a fixing block 14, a spring 15, a second rotating cylinder 16, a fan 17, a guide plate 22, and a controller 23. The support frame 2 is welded to the bottom of the outer frame 1. Rounded rectangular feed troughs and discharge troughs are opened in the middle of both the left and right sides of the outer frame 1. Guide plates 22 are welded to the feed troughs. The base plate 3 is bolted to the top of the support frame 2. The base plate 3 is located inside the outer frame 1. A row of heating tubes 4 is bolted to the inside of the base plate 3 in a linear array. Multiple through holes are opened in a rectangular array at the top of the base plate 3. The first support column 7 is bolted to the front left side of the support frame 2. The first motor 8 is bolted to the upper inside of the first support column 7. The first rotating cylinder 9 is keyed to the output shaft of the first motor 8. The second fixed columns 1 are symmetrically welded to the front and back of the right side of the base plate 3. 2. A first rotating cylinder 9 is rotatably connected between two second fixed columns 12. A handle 13 is slidably connected to the top of the outer frame 1 on both sides. The two handles 13 extend downward into the interior of the outer frame 1 and correspond to the positions of the two first rotating cylinders 9. Fixed blocks 14 are welded symmetrically to the bottom of the two handles 13. A spring 15 is wound around the handle 13. One end of the spring 15 is fixedly connected to the fixed block 14, and the other end of the spring 15 is fixedly connected to the outer frame 1. A second rotating cylinder 16 is rotatably connected between the two symmetrical fixed blocks 14. The second rotating cylinder 16 is located above the first rotating cylinder 9, and there is a certain gap between them. This gap corresponds to the position of the discharge chute. A fan 17 is connected to the top right side of the outer frame 1 by bolts. Three ventilation slots are opened on the top left side of the outer frame 1. A controller 23 is connected to the upper left outer wall of the first support column 7 by bolts. The first motor 8 and the heating tube 4 are electrically connected to the controller 23.

[0023] like Figure 2 , Figure 3 and Figure 5As shown, it also includes a first fixed column 5, a sponge roller 6, a pulley 10 and a rubber belt 11. The first fixed column 5 is symmetrically fixedly connected to the left side of the base plate 3. The upper and middle parts of the two first fixed columns 5 are rotatably connected to the sponge roller 6. There is a certain gap between the two sponge rollers 6, and the gap corresponds to the position of the feed chute. The front end of the sponge roller 6 located in the middle of the first fixed column 5 is fixedly connected to the pulley 10. Another pulley 10 is fixedly connected to the output shaft of the first motor 8. A rubber belt 11 is sleeved between the two pulleys 10.

[0024] During the transmission phase, the bare copper wire enters the feed chute through the guide plate 22. There is a gap between the two sponge rollers 6 corresponding to the feed chute positions. The bare copper wire passes through this gap. Then, the controller 23 starts the first motor 8. The first motor 8 drives the sponge roller 6 located in the middle of the first fixed column 5 to rotate via the pulley 10 and rubber belt 11. The sponge roller 6 can initially wipe the surface of the bare copper wire, removing some moisture and impurities, and simultaneously convey the bare copper wire to the next position. Afterwards, the two handles 13 are pulled upwards, causing the fixed block 14 to move upwards as well. At this time, the spring 15 is compressed, and the bare copper wire... When the wire passes through the gap, the handle is released. Under the reset action of the spring 15, the second rotating cylinder 16 will fit against the first rotating cylinder 9 under pressure. Both the first rotating cylinder 9 and the second rotating cylinder 16 are covered with anti-slip sleeves. The rotation of the first motor 8 drives the first rotating cylinder 9 to rotate together. The anti-slip sleeves increase the friction and transmit the bare copper wire. At the same time, the other first rotating cylinder 9, which is rotatably connected between the second fixed columns 12 symmetrically arranged on the right side of the base plate 3, also assists in the conveying of the bare copper wire, so that the bare copper wire can move smoothly from the feed trough to the discharge trough.

[0025] During the drying stage, after entering the dryer, the heating tubes 4 are activated by the controller 23. The bare copper wire is positioned above the base plate 3. A row of heating tubes 4, fixedly connected in a linear array inside the base plate 3, begins to work. The heat generated by the heating tubes 4 is dissipated through multiple through holes in a rectangular array at the top of the base plate 3, forming a uniform heat flow that heats and dries the bare copper wire. At the same time, the fan 17, fixedly connected to the top right side of the outer frame 1, is activated. The operation of the fan 17 accelerates the airflow, and the air enters from the three ventilation slots on the top left side of the outer frame 1, forming a directional airflow that promptly removes the evaporated water vapor, maintaining a dry drying environment.

[0026] like Figure 1 and Figure 6As shown, it also includes a second support column 18, a second motor 19, a winding shaft 20, and a support block 21. The second support column 18 is fixedly connected to the front right side of the support frame 2. The second motor 19 is connected to the top of the second support column 18 by bolts. The winding shaft 20 is keyed to the output shaft of the second motor 19. The support blocks 21 are symmetrically welded to the top right side of the support frame 2. The winding shaft 20 is located between the two support blocks 21 and is rotatably connected to the support blocks 21. The second motor 19 is electrically connected to the controller 23.

[0027] During the winding stage of this device, after the bare copper wire is dried and comes out of the discharge trough, the second motor 19 is started by the controller 23. The second motor 19 drives the winding shaft 20 fixedly connected to the output shaft to rotate. The rotating winding shaft 20 winds and collects the dried bare copper wire, and organizes the dried bare copper wire in an orderly manner.
