A copper wire is arranged on the constant-speed wheel, and a lead wheel is also arranged along the direction of the copper wire. The annealing box is arranged outside the copper wire at the output end of the lead wheel. A plurality of heating wires are arranged inside the annealing box, and the heating wires are sleeved outside the copper wire. One end of the copper wire extends into the immersion tank, and an idler wheel and a take-up wheel are respectively arranged at the wire end of the copper wire led out from the immersion tank. The limiting mechanism includes a limiting block and a sealing plate. A limiting groove is opened on the upper surface of the limiting block, and a limiting wheel is fixedly arranged on the lower surface of the sealing plate.

[0004] The copper wire obtained in the above patent document has stable and reliable quality, can remove surface impurities, and limits the diameter of the copper wire. However, part of the moisture residue will adhere to the surface of the copper wire after cooling, and local oxidation will occur on the surface of the copper wire during transportation, affecting the use performance of the copper wire.

Detailed Embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0022] Reference Figures 1 - 7 As shown in the figure, the continuous annealing device for copper wire drawing includes a base 1, on which a casing 4 is fixedly installed. Inside the casing 4, there are an annealing chamber 21, a cooling chamber 22 and a water removal chamber 23. An inner hole for the copper wire to pass through is provided between the cooling chamber 22 and the water removal chamber 23, and an outer hole communicating with the water removal chamber 23 is provided on the upper surface of the casing 4. A roller 3 is rotatably installed on the upper surface of the casing 4 through a support frame. A fixed rod 6 is fixedly installed on the side of the roller 3. One end of the fixed rod 6 away from the roller 3 is rotatably installed with a rocker 7. Rectangular holes are provided on the front and rear walls of the casing 4. Two sliders 8 are slidably installed in the two rectangular holes. Two trapezoidal blocks 9 are fixedly installed on the two sliders 8. The two trapezoidal blocks 9 are respectively in sliding contact with the front and rear walls of the casing 4. A rectangular hole is provided on the upper surface of the casing 4. One end of the rocker 7 away from the fixed rod 6 passes through the rectangular hole and is rotatably connected to one of the trapezoidal blocks 9. Grooves 10 are provided on the opposite sides of the two trapezoidal blocks 9. A plurality of triangular blocks 11 arranged vertically and equidistantly are fixedly installed in the grooves 10. Pressing plates 12 are symmetrically installed in the water removal chamber 23 through a support assembly. A water-absorbing cotton 13 is fixedly installed between the two pressing plates 12. A cylindrical hole is provided in the water-absorbing cotton 13. A push rod 14 is fixedly installed on the side of each of the two pressing plates 12. One end of the push rod 14 extends into the groove 10 and is in sliding contact with the inclined surface of the triangular block 11.

[0023] A traction assembly for pulling the copper wire is provided on the base 1. The traction assembly includes a traction roller 2 rotatably installed on the base 1. The traction roller 2 and the roller 3 are in the same vertical plane (a driving device is fixedly installed on the traction assembly, not shown in the figure). Before starting the driving device, one end of the copper wire is passed through the outer hole of the water removal chamber 23 and the roller 3 and wound around the traction roller 2. At this time, the driving device drives the traction roller 2 to rotate, and the copper wire is collected and wound around the traction roller 2.

[0024] The support assembly includes two telescopic springs 15 and two sliding rods 16. Rectangular grooves are symmetrically provided on the inner top wall of the casing 4. The two sliding rods 16 are respectively fixedly installed on the upper surfaces of the two pressing plates 12. One end of the telescopic spring 15 is fixedly installed on the inner wall of the rectangular groove, and the other end is fixedly installed on the side of the sliding rod 16. The end of the sliding rod 16 away from the pressing plate 12 is slidably installed in the rectangular groove. Under the elastic force of the telescopic spring 15, the two sliding rods 16 are driven to move away from each other, so that one end of the two push rods 14 extends into the groove 10 of the trapezoidal block 9 and is in sliding contact with the inclined surface of the triangular block 11.

[0025] The copper wire passes through the annealing chamber 21 in sequence for high-temperature annealing, and then enters the cooling chamber 22. There is a large amount of cooling water in the cooling chamber 22. When the machine starts to work, the traction roller 2 drives the copper wire to move inside the machine housing 4. Since the copper wire passes through the cylindrical holes formed in the water-absorbing cotton 13, the water-absorbing cotton 13 will absorb the residual cooling water on the copper wire. At the same time, the copper wire drives the roller 3 to rotate. When the roller 3 rotates, it drives the trapezoidal block 9 to reciprocate in the water removal chamber 23 through the fixed rod 6 and the rocker 7. The slider 8 fixed on the trapezoidal block 9 slides in the rectangular hole. During the up-and-down movement of the trapezoidal block 9, it will drive the relative movement of the multiple triangular blocks 11 and the ejector rod 14 in the groove 10. Under the elastic force of the telescopic spring 15, one end of the ejector rod 14 will drive it to slide along the inclined surface of the triangular block 11, thereby driving the two pressing plates 12 to move relative to each other. When the two pressing plates 12 approach each other, they will squeeze the water-absorbing cotton 13, squeeze out the water on the water-absorbing cotton 13, and thus remove the residual cooling water on the copper wire, avoiding the oxidation of the copper wire by the residual cooling water and ensuring the production quality of the copper wire.

[0026] The water collection device includes a water collection tank 17 and a filter plate 18 fixedly installed on the base 1. The inner side wall of the water collection tank 17 is provided with a U-shaped groove for placing the filter plate 18. The side surface of the water collection tank 17 is provided with a rectangular hole communicating with the U-shaped groove. The filter plate 18 passes through the rectangular hole and is slidably inserted into the U-shaped groove. The inner wall of the water removal chamber 23 is provided with a plurality of circular holes all communicating with the inside of the water collection tank 17. The water collection tank 17 and the cooling chamber 22 are connected through a U-shaped pipe 19. The upper surface of the water collection tank 17 is provided with a connection hole, and a water injection pipe 5 is fixedly installed in the connection hole. After the copper wire passes through the high-temperature annealing in the annealing chamber 21 and enters the cooling chamber 22, it will consume a large amount of cooling water in the cooling chamber 22. At this time, the staff can add water to the water collection tank 17 through the water injection pipe 5 and then add water to the cooling chamber 22 through the U-shaped pipe 19.

[0027] The bottom wall of the water removal chamber 23 is fixedly installed with an inclined block 20. The inclined block 20 is provided with a circular hole corresponding to the inner hole, which is convenient for the penetration of the copper wire. When the two pressing plates 12 are mutually extruded, the water on the water-absorbing cotton 13 will flow to the bottom wall of the water removal chamber 23. Under the guiding action of the inclined block 20, the water flow will flow along the direction of the inclined block 20 through the circular holes communicating with the inside of the water removal chamber 23 and the water collection tank 17, and flow into the water collection tank 17 after being filtered by the filter plate 18. Since there are some impurities in the cooling water on the surface of the copper wire, the water squeezed out from the water-absorbing cotton 13 needs to be filtered. Since the copper wire will continuously consume the water in the cooling chamber 22 when passing through the cooling chamber 22, at this time, the U-shaped pipe 19 will lead the water in the water collection tank 17 to the cooling chamber 22.

[0028] When the utility model is in use, after the copper wire is annealed and cooled in the cooling bin 22, excess cooling water will remain on the surface. At this time, the traction roller 2 drives the roller 3 to rotate through the copper wire. The roller 3 drives the trapezoidal block 9 to reciprocate in the water removal bin 23 through the fixed rod 6 and the rocker 7. The slider 8 fixed on the trapezoidal block 9 slides in the rectangular hole. During the up and down movement of the trapezoidal block 9, it will drive the relative movement of the multiple triangular blocks 11 and the ejector rod 14 in the groove 10. Under the elastic force of the telescopic spring 15, one end of the ejector rod 14 will drive and slide along the inclined surface of the triangular block 11, thereby driving the two pressing plates 12 to move relative to each other. When the two pressing plates 12 approach each other, they will squeeze the absorbent cotton 13, and squeeze out the water on the absorbent cotton 13. This working process can remove the residual cooling water on the copper wire, keep the copper wire dry, avoid the oxidation of the copper wire by the residual cooling water, and ensure the production quality of the copper wire.
