Description

Technical Field

[0001] This application relates to the field of cable production equipment, and in particular to a copper wire pretreatment device for ultra-low resistance copper wire braided water-blocking tape. Background Technology

[0002] Cable water-blocking tape is a waterproof material used for cables or optical cables. It is mainly composed of water-absorbing material and fiber fabric (base tape). It absorbs water and expands to block the water penetration channels, preventing water intrusion that could lead to short circuits, corrosion, or signal attenuation. This ensures electrical insulation performance and signal transmission stability. To further improve the stability of cable signal output, some cables are covered with metal mesh, which mainly serves as a shield and can greatly improve the signal's anti-interference strength.

[0003] Currently, water-blocking tape and wire mesh on cables are usually processed in layers on the outside of the cable. This production process places extremely high demands on the production equipment. While pre-weaving the metal wires onto the water-blocking tape and then wrapping the tape around the outside of the cable can greatly reduce the equipment requirements, the significant difference in hardness between the metal wires and the base material of the water-blocking tape can easily lead to large gaps between the surface of the metal wires and the base material of the water-blocking tape during the wrapping process. In severe cases, this can affect the water-blocking effect of the absorbent material on the water-blocking tape, thus presenting a drawback. Utility Model Content

[0004] In order to improve the problem of reduced water blocking effect after the braided metal wires are added to the water blocking tape, this application provides a copper wire pretreatment device for ultra-low resistance copper wire braided water blocking tape.

[0005] The copper wire pretreatment device for ultra-low resistance copper wire braided water-blocking tape provided in this application adopts the following technical solution: A copper wire pretreatment device for ultra-low resistance copper wire braided water-blocking tape includes an unwinding machine and a winding machine. An unwinding roller is rotatably mounted on the unwinding machine, and a winding roller is rotatably mounted on the winding machine. Metal wire unwound from the unwinding roller is wound onto the winding roller. An immersion tank is arranged between the unwinding machine and the winding machine, containing a liquid absorbent material. An immersion rack is arranged within the immersion tank, and multiple guide wheels are rotatably mounted on the immersion rack. The metal wire sequentially passes over the multiple guide wheels on the immersion rack. A hollow drying chamber is arranged between the immersion tank and the winding machine, with an inlet and an outlet for the metal wire to pass through. The drying chamber is equipped with a drying element for drying the absorbent material on the surface of the metal wire.

[0006] By adopting the above technical solution, as the metal wire unwound from the unwinding roller slides from the guide wheel on the immersion rack to the drying box, the surface of the metal wire will be coated with liquid absorbent material from the immersion tank. The drying component will dry and solidify the liquid absorbent material on the surface of the metal wire passing through the drying box. The dried metal wire will be wound on the take-up roller, so that the surface of the metal wire is coated with absorbent material. When the treated metal wire is woven into the water-blocking tape, even if there is a gap between the metal wire and the base of the water-blocking tape, the absorbent material on the surface of the metal wire can absorb water and expand, thereby reducing the gap between the metal wire and the base of the water-blocking tape, thus preventing the continued diffusion of moisture and ensuring the water-blocking effect of the cable.

[0007] Optionally, a stress table is provided between the unwinding machine and the immersion tank. A straightening plate is provided on the stress table, and multiple end wheels are rotatably arranged on the straightening plate. The multiple end wheels are evenly arranged along the direction from the unwinding machine to the stress table. A pressing strip is slidably arranged on the straightening plate, and a stress cylinder electrically connected to the control system is provided on the straightening plate. The pressing strip is arranged on the piston rod of the stress cylinder, and multiple pressure rollers are rotatably arranged on the pressing strip. The multiple pressure rollers are evenly arranged along the direction from the unwinding machine to the stress table. The end wheels and the pressure rollers are arranged alternately, and the metal wire passes between the end wheels and the pressure rollers.

[0008] By adopting the above technical solution, the control system starts the stress cylinder. The piston rod of the stress cylinder extends and drives the pressing strip to slide synchronously. The pressing strip drives the pressure roller to press the metal wire passing between the end roller and the pressure roller onto the end roller. Through the squeezing of the end roller and the pressure roller, the metal stress formed on the metal wire due to winding on the unwinding roller is eliminated, thereby facilitating the subsequent processing of the metal wire.

[0009] Optionally, two cleaning plates are provided between the correction plate and the immersion tank, and cleaning sponges are provided on the cleaning plates, with metal wires passing between the two cleaning sponges.

[0010] By adopting the above technical solution, impurities attached to the surface of the metal wire will be removed during the process of the metal wire passing through two cleaning sponges, thereby improving the quality of the water-absorbing material subsequently attached to the surface of the metal wire.

[0011] Optionally, a horizontal plate is provided on the immersion tank, the immersion rack is vertically slidably engaged with the horizontal plate, a top plate is provided on the immersion rack and above the horizontal plate, and an adjusting compression spring is provided between the top plate and the horizontal plate.

[0012] By adopting the above technical solution, during the conveying process, the tension of the metal wire may suddenly increase or decrease. The adjusting spring can use its elastic properties to make the dip frame slide in the vertical direction, thereby adapting to the sudden tension changes of the metal wire during the conveying process and reducing the possibility of the metal wire breaking or detaching from the guide wheel.

[0013] Optionally, a transition wheel is rotatably provided at both the inlet and outlet of the drying chamber, and the metal wire passes around the transition wheel. An inclined return plate is provided between the inlet of the drying chamber and the immersion tank. The cross-section of the return plate is U-shaped, and the lowest inclined end of the return plate is located above the immersion tank.

[0014] By adopting the above technical solution, during the process of the metal wire sliding to the inlet of the drying box, the liquid water-absorbing material adhering to the surface of the metal wire will drip onto the return plate. The liquid water-absorbing material gathered on the return plate will flow back into the immersion tank along the inclined return plate, thereby reducing the waste of water-absorbing material.

[0015] Optionally, the drying component includes an electric heating plate disposed inside the drying chamber, and a fan is disposed on the top of the drying chamber. Both the electric heating plate and the fan are electrically connected to the control system.

[0016] By adopting the above technical solution, the control system starts the electric heating plate and the fan. The heat generated by the electric heating plate heats the metal wire, causing the water-absorbing material on the surface of the metal wire to continuously dehydrate and dry. Meanwhile, the fan quickly exhausts the hot and humid air in the drying chamber, and the dry and cold air from the outside flows into the drying chamber through the inlet and outlet, thereby quickly drying the water-absorbing material on the surface of the metal wire.

[0017] Optionally, the drying oven is hinged with an access door.

[0018] By adopting the above technical solution, it is convenient for workers to carry out maintenance and also convenient for workers to thread metal wires.

[0019] Optionally, a cycloidal frame is provided between the winding machine and the drying chamber. A fixed wire ring is provided on the cycloidal frame, and a cycloidal screw is rotatably provided on the cycloidal frame. The axis of the cycloidal screw is parallel to the axis of the winding roller. A guide post is provided on the cycloidal frame, and the axis of the guide post is parallel to the axis of the cycloidal screw. A cycloidal block is threadedly connected to the cycloidal screw. The cycloidal block is slidably sleeved on the guide post. A moving wire ring is provided on the cycloidal block. A cycloidal motor electrically connected to the control system is provided on the cycloidal frame. The cycloidal screw is coaxially provided on the output shaft of the cycloidal motor. The metal wire passes through the fixed wire ring to the moving wire ring and then winds around the winding roller.

[0020] By adopting the above technical solution, during the process of the winding machine winding the processed metal wire through the winding roller, the control system starts the cycloidal motor. The output shaft of the cycloidal motor drives the cycloidal screw to rotate in the forward direction. Under the guidance of the guide post, the cycloidal block drives the moving wire ring to slide along the axis of the guide post. Then, the control system controls the output shaft of the cycloidal motor to rotate in the direction of rotation, so as to evenly wind the processed metal wire onto the winding roller.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. As the unwound metal wire slides from the guide roller on the immersion rack into the drying chamber, the surface of the metal wire will be coated with liquid absorbent material from the immersion tank. The drying unit will dry and solidify the liquid absorbent material on the surface of the metal wire as it passes through the drying chamber. The dried metal wire will then be wound onto the take-up roller, so that the surface of the metal wire is coated with absorbent material. When the treated metal wire is woven into the water-blocking tape, even if there is a gap between the metal wire and the base of the water-blocking tape, the absorbent material on the surface of the metal wire can absorb water and expand, thereby reducing the gap between the metal wire and the base of the water-blocking tape, thus preventing the continued diffusion of moisture and ensuring the water-blocking effect of the cable. 2. During the conveying process, the tension of the metal wire may suddenly increase or decrease. The adjusting spring can use its elastic properties to make the dip frame slide vertically to adapt to the sudden tension changes of the metal wire during the conveying process, thereby reducing the possibility of the metal wire breaking or falling off the guide wheel. 3. The control system starts the electric heating plate and the fan. The heat generated by the electric heating plate heats the metal wire, causing the liquid absorbent material on the surface of the metal wire to continuously dehydrate and dry. Meanwhile, the fan quickly exhausts the hot and humid air in the drying chamber, and the dry and cold air from the outside flows into the drying chamber through the inlet and outlet, thereby quickly drying the absorbent material on the surface of the metal wire.

[0028] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0029] This application discloses a copper wire pretreatment device for ultra-low resistance copper wire braided water-blocking tape.

[0030] Reference Figure 1 A copper wire pretreatment device for ultra-low resistance copper wire braided water-blocking tape includes an unwinding machine 1 and a winding machine 2.

The metal wire unwound on the unwinding roller 3 is wound around the winding roller 4.

[0031] Reference Figure 1 and Figure 2 An immersion tank 5 is arranged between the unwinder 1 and the rewinder 2. The immersion tank 5 is filled with a liquid absorbent material. A stress table 12 is arranged between the unwinder 1 and the immersion tank 5. A straightening plate 13 is bolted to the stress table 12. Multiple end wheels 14 are rotatably connected to the straightening plate 13. The multiple end wheels 14 are evenly arranged along the direction from the unwinder 1 to the stress table 12.

[0032] Reference Figure 2 A pressing strip 15 is slidably arranged on the straightening plate 13. A stress cylinder 16, which is electrically connected to the control system, is bolted to the straightening plate 13. The pressing strip 15 is bolted to the piston rod of the stress cylinder 16. Multiple pressure rollers 17 are rotatably connected to the pressing strip 15. The multiple pressure rollers 17 are evenly arranged along the direction from the unwinding machine 1 to the stress table 12. The end rollers 14 and the pressure rollers 17 are arranged alternately. The metal wire passes through the end rollers 14 and the pressure rollers 17.

[0034] As the unwound metal wire passes through the two cleaning sponges 19, the control system activates the stress cylinder 16. The piston rod of the stress cylinder 16 extends and drives the pressing bar 15 to slide synchronously. The pressing bar 15 drives the pressure roller 17 to press the metal wire onto the end roller 14. Through the squeezing of the end roller 14 and the pressure roller 17, the metal stress formed on the metal wire due to winding on the unwound roller 3 is eliminated.

[0035] Reference Figure 1 , Figure 3 and Figure 4 A horizontal plate 20 is bolted to the immersion tank 5. An immersion rack 6 is vertically slidably arranged on the horizontal plate 20. A top plate 21 is welded on the immersion rack 6 and above the horizontal plate 20. An adjusting spring 22 supports the top plate 21 and the horizontal plate 20. Multiple guide wheels 7 are rotatably connected to the immersion rack 6. Metal wires pass around the multiple guide wheels 7 on the immersion rack 6 in sequence.

[0036] Reference Figure 1 and Figure 3 A hollow drying box 8 is arranged between the immersion tank 5 and the winding machine 2. The drying box 8 is hinged with an inspection door 25. The drying box 8 has an inlet 9 and an outlet 10 for the metal wire to pass through. Both the inlet 9 and the outlet 10 of the drying box 8 are rotatably connected to a transition wheel 23, and the metal wire passes around the transition wheel 23.

[0037] Reference Figure 1 and Figure 3 An inclined return plate 24 is arranged between the inlet 9 of the drying chamber 8 and the immersion tank 5. The cross-section of the return plate 24 is U-shaped, and the lowest inclined end of the return plate 24 is located above the immersion tank 5.

[0038] The stress-relieving metal wire passes through the liquid absorbent material in the immersion tank 5 via the guide wheel 7, thereby causing a large amount of liquid absorbent material to adhere to the surface of the metal wire. As the metal wire passes over the return plate 24, the liquid absorbent material dripping from the surface of the metal wire will flow back into the immersion tank 5 along the inclined return plate 24.

[0039] Reference Figure 1 and Figure 3 The drying chamber 8 is equipped with a drying element 11 for drying the water-absorbing material on the surface of the metal wire. The drying element 11 includes an electric heating plate 111 bolted inside the drying chamber 8. A fan 112 is bolted to the top of the drying chamber 8. Both the electric heating plate 111 and the fan 112 are electrically connected to the control system.

[0040] Reference Figure 1 and Figure 5 A cycloidal frame 26 is arranged between the winding machine 2 and the drying box 8. A fixed wire ring 27 is bolted to the cycloidal frame 26. A cycloidal screw 28 is rotatably connected to the cycloidal frame 26. The axis of the cycloidal screw 28 is parallel to the axis of the winding roller 4. A guide post 29 is bolted to the cycloidal frame 26. The axis of the guide post 29 is parallel to the axis of the cycloidal screw 28. A cycloidal block 30 is threadedly connected to the cycloidal screw 28.

[0041] Reference Figure 5 The cycloidal block 30 is slidably sleeved on the guide post 29. A moving wire ring 31 is bolted to the cycloidal block 30. A cycloidal motor 32 electrically connected to the control system is bolted to the cycloidal frame 26. The cycloidal screw 28 is coaxially bolted to the output shaft of the cycloidal motor 32. The metal wire passes through the ring of the fixed wire ring 27 into the ring of the moving wire ring 31 and then winds around the take-up roller 4.

[0042] As the metal wires coated with liquid absorbent material pass through the drying chamber 8, the control system is activated. The electric heating plate 111 and the fan 112 generate heat to heat the metal wires, causing the liquid absorbent material on the surface of the metal wires to continuously dehydrate and dry.

[0043] The fan 112 will quickly expel the hot and humid air from the drying chamber 8, while the dry and cold air from the outside will flow into the drying chamber 8 through the inlet 9 and outlet 10, thereby quickly drying the water-absorbing material on the surface of the metal wire and thus attaching a layer of water-absorbing material to the surface of the metal wire.

[0044] When metal wires coated with absorbent material are woven into the water-blocking tape, even if gaps appear between the metal wires and the base of the water-blocking tape, the absorbent material on the surface of the metal wires can absorb water and expand, and together with the absorbent material on the water-blocking tape, eliminate the gaps between the metal wires and the base of the water-blocking tape, thereby preventing the continued diffusion of moisture and ensuring the water-blocking effect of the cable.

[0045] The implementation principle of the copper wire pretreatment device for ultra-low resistance copper wire braided water-blocking tape in this application embodiment is as follows: When the metal wire unwound on the unwinding roller 3 passes through two cleaning sponges 19, the control system activates the stress cylinder 16. The piston rod of the stress cylinder 16 extends and drives the pressing strip 15 to slide synchronously. The pressing strip 15 drives the pressure roller 17 to press the metal wire onto the end roller 14. Through the squeezing of the end roller 14 and the pressure roller 17, the metal stress formed on the metal wire due to winding on the unwinding roller 3 is eliminated.

[0046] The stress-relieving metal wire passes through the liquid absorbent material in the immersion tank 5 via the guide wheel 7, thereby causing a large amount of liquid absorbent material to adhere to the surface of the metal wire. As the metal wire passes over the return plate 24, the liquid absorbent material dripping from the surface of the metal wire will flow back into the immersion tank 5 along the inclined return plate 24.

[0047] As the metal wires coated with liquid absorbent material pass through the drying chamber 8, the control system is activated. The electric heating plate 111 and the fan 112 generate heat to heat the metal wires, causing the liquid absorbent material on the surface of the metal wires to continuously dehydrate and dry.

[0048] The fan 112 will quickly expel the hot and humid air from the drying chamber 8, while the dry and cold air from the outside will flow into the drying chamber 8 through the inlet 9 and outlet 10, thereby quickly drying the water-absorbing material on the surface of the metal wire and thus attaching a layer of water-absorbing material to the surface of the metal wire.

[0049] When metal wires coated with absorbent material are woven into the water-blocking tape, even if gaps appear between the metal wires and the base of the water-blocking tape, the absorbent material on the surface of the metal wires can absorb water and expand, and together with the absorbent material on the water-blocking tape, eliminate the gaps between the metal wires and the base of the water-blocking tape, thereby preventing the continued diffusion of moisture and ensuring the water-blocking effect of the cable.
