Description

Technical Field

[0001] This invention belongs to the field of cable processing technology and relates to a cable copper wire and copper tape shielding machine. Background Technology

[0002] Copper wire and copper tape shielding is an important functional structure in cable design, primarily used to block electromagnetic interference and ensure the safe and stable operation of the cable through a metallic shielding layer. Copper wire and copper tape shielding machines are key equipment in wire and cable manufacturing, specifically designed to continuously, tightly, and uniformly wrap metal wires or metal tapes around the cable core as a shielding layer.

[0003] In current copper wire and tape shielding machines, the circular wire-passing device has wire-passing holes along its circumference. During production, the copper wire passes through these holes. The number of wire-passing holes in the device is fixed, but different models and specifications of shielded cables have varying fault and short-circuit current requirements, necessitating different numbers of copper wires for shielding. When the fixed number of wire-passing holes does not match the actual required number of copper wires, it leads to uneven spacing of the copper wires during production, disrupting the uniformity and integrity of the shielding layer. Consequently, the copper wire shielding cannot fully perform its electromagnetic shielding and safety protection functions, affecting the overall performance of the cable.

[0004] To address the above problems, this invention proposes a cable copper wire and copper tape shielding machine. Summary of the Invention

[0005] To address the problems existing in the background technology, the present invention proposes a cable copper wire and copper tape shielding machine.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A cable copper wire and copper tape shielding machine includes a rotating drum, a wire feeding mechanism, and a wire feeder; the wire feeding mechanism is mounted on the rotating drum.

[0008] The wiring device includes an annular plate fixed on a rotating drum, movable blocks, and sliding wire guide blocks. Multiple movable blocks are slidably arranged axially on the outer circumference of the annular plate. A T-shaped groove is formed on the annular plate, within which a T-shaped slider fixedly connected to a movable block is slidably arranged. A sliding wire guide block is movably arranged within each movable block. An arc-shaped through groove is formed on the annular plate to cooperate with the sliding wire guide block, and an arc-shaped groove is formed on the annular plate to cooperate with the T-shaped slider. The T-shaped slider moves from the T-shaped groove to the arc-shaped groove, and then the sliding wire guide block passes through the arc-shaped through groove to facilitate wire passage. Connectors are provided between adjacent movable blocks from one end to the other.

[0009] The connecting component includes a first connecting rod and a second connecting rod; between two adjacent movable blocks, the first connecting rod and the second connecting rod are rotatably connected to the two movable blocks respectively, the first connecting rod is connected to a shaft, and the second connecting rod is provided with a rotating hole that mates with the shaft.

[0010] Furthermore, a limiting groove for accommodating the sliding line block is provided on the inner wall of the T-shaped groove.

[0011] Furthermore, a fixing component for fixing the T-shaped slider is provided in the arc-shaped groove; the fixing component includes an iron sheet fixed in the arc-shaped groove, and an electromagnet is installed on the side of the T-shaped slider near the arc-shaped groove.

[0012] Furthermore, a ball bearing is installed at one end of the T-shaped slider near the arc-shaped groove.

[0013] Furthermore, a fixed block is provided between the movable block at the beginning and the movable block at the end, and the fixed block is fixedly connected to the annular plate; a fixed wire guide block is fixedly connected to the fixed block; a connecting member is provided between the fixed block and the movable block at the beginning, and a first connecting rod is rotatably connected to the fixed block and a second connecting rod is rotatably connected to the movable block at the beginning.

[0014] Furthermore, the first and second links on the same movable block are connected by a transmission, and the first and second links on the same movable block rotate in opposite directions.

[0015] Furthermore, the rotating drum is rotatably mounted on the base; a motor is mounted on the base, the output shaft of the motor is fixedly connected to a drive gear, and a driven gear that meshes with the drive gear is fixedly connected to the rotating drum.

[0016] Furthermore, the wire feeding mechanism includes a turntable, which is fixedly connected to a rotating drum. Multiple fixing rods are installed on the turntable, and the fixing rods are used to install copper wire coils.

[0017] Compared with the prior art, the present invention has the following advantages: Based on the number of copper wires wound on the cable, the required movable blocks are moved sequentially from the first end to the threading station. The fixed block and the movable block located at the threading station are connected in sequence by connectors. By rotating the first and second connecting rods, the movable block slides along the arc-shaped through groove. Rotating the first and second connecting rods by a certain angle allows the movable block and fixed block at the threading station to be evenly distributed along the circumference of the annular plate, ensuring that the copper wires passing through the wiring device are evenly distributed circumferentially along the axis of the rotating drum, thus facilitating the uniform winding of the copper wires onto the cable.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1-18 As shown, the technical solution adopted by the present invention is as follows: A cable copper wire and copper tape shielding machine includes a rotating drum 2, a wire feeding mechanism, and a wire connector 10. The rotating drum 2 is rotatably mounted on a base 1. Both the wire feeding mechanism and the wire connector 10 are mounted on the rotating drum 2. An unwinding device is provided on one side of the base 1, and a winding device is provided on the other side. A wire connector 11 is provided between the base 1 and the winding device. One end of the cable 12 is connected to the unwinding device, and the other end of the cable 12 passes through the rotating drum 2 and the wire connector 11 in sequence before being connected to the winding device. The unwinding device unwinds the cable 12, and the winding device winds the cable 12, causing the cable 12 to move along the rotating drum 2 toward the winding device and gradually wrap around the winding device. The rotating drum 2 rotates relative to the base 1, causing the copper wire to gradually wrap around the cable 12. The wire connector 11 is used to clamp the copper wire and the cable 12. The winding device and the unwinding device are existing technologies and will not be described in detail here, nor are they shown in the figures.

[0039] like Figure 2 As shown, a motor 4 is fixedly mounted on the base 1. The output shaft of the motor 4 is fixedly connected to a drive gear 5, which meshes with a driven gear 3. The driven gear 3 is fixedly sleeved on the rotating drum 2. The motor 4 drives the rotating drum 2 to rotate through the drive gear 5 and the driven gear 3.

[0040] like Figure 1As shown, the wire feeding mechanism includes a turntable 6, which is fixedly mounted on a rotating drum 2. Multiple fixing rods 7 are installed on the side of the turntable 6 near the wire combiner 11, and these fixing rods 7 are evenly distributed circumferentially along the axis of the rotating drum 2. The fixing rods 7 are used to mount copper wire coils 8. Multiple guide wheels 9 are fixedly mounted on the turntable 6, and these guide wheels 9 are evenly distributed circumferentially along the axis of the rotating drum 2, with each guide wheel 9 corresponding to one of the fixing rods 7. One end of the copper wire on the copper wire coil 8 passes through the corresponding guide wheel 9 and extends into the wiring device 10. After passing through the wiring device 10, the copper wire is fixedly connected to the cable 12.

[0041] The wiring device 10 includes a ring plate 14, a movable block 21, and a sliding wire guide block 31. For example... Figure 3 As shown, the annular plate 14 is coaxially arranged with the rotating drum 2, and the annular plate 14 is fixedly connected to the rotating drum 2 through the connecting plate 13.

[0042] like Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, multiple T-shaped grooves 15 are formed on the outer circumference of the annular plate 14. Limiting grooves 16 are formed on the inner wall of each T-shaped groove 15 near the axis of the annular plate 14. A T-shaped slider 22 is slidably disposed within each T-shaped groove 15. Each T-shaped slider 22 is fixedly connected to a movable block 21, which slides in contact with the circumferential surface of the annular plate 14. The sliding direction of the movable block 21 is parallel to the axial direction of the annular plate 14. A sliding guide block 31 is slidably connected to the movable block 21. Specifically, a clearance groove is formed on the movable block 21, and the sliding guide block 31 is slidably disposed within the clearance groove. An electric push rod 32 is fixedly installed within the movable block 21, and the telescopic end of the electric push rod 32 is fixedly connected to the sliding guide block 31. When the movable block 21 is at one end of the T-shaped groove 15 near the wiring mechanism, the sliding wire block 31 is directly opposite the limiting groove 16. The sliding wire block 31 is moved outside the movable block 21 by the electric push rod 32, so that the sliding wire block 31 is inserted into the limiting groove 16, thereby limiting the movable block 21 and preventing the movable block 21 from sliding.

[0043] An annular plate 14 has an arc-shaped through groove 17 and an arc-shaped recess 18. Both the arc-shaped through groove 17 and the arc-shaped recess 18 are coaxially arranged with the annular plate 14. The arc-shaped through groove 17 is located between the arc-shaped recess 18 and the T-shaped slide groove 15. An electric push rod 32 retracts the sliding wire guide block 31 into the clearance groove, and then the movable block 21 moves along the T-shaped slide groove 15 towards the arc-shaped recess 18, causing the T-shaped slider 22 to move into the arc-shaped recess 18 and then out of the T-shaped slide groove 15. At this point, the sliding wire guide block 31 is directly opposite the arc-shaped through groove 17. Afterwards, the electric push rod 32 moves the sliding wire guide block 31 towards the axis of the annular plate 14, causing the sliding wire guide block 31 to pass through the arc-shaped through groove 17 and extend into the inner side of the annular plate 14 for wire passage.

[0044] A fixing element for fixing the movable block 21 is provided within the arc-shaped groove 18. The fixing element includes an iron sheet 19, and an electromagnet 29 is embedded and fixedly installed within the T-shaped slider 22 near the side of the arc-shaped groove 18. When the T-shaped slider 22 is within the arc-shaped groove 18 and the electromagnet 29 is energized, the T-shaped slider 22 is attracted to the iron sheet 19 by the electromagnet 29, and the T-shaped slider 22 is fixed within the arc-shaped groove 18, thereby fixing the movable block 21 to the annular plate 14.

[0045] A ball bearing 30 is installed on the side of the T-shaped slider 22 near the arc-shaped groove 18. When the T-shaped slider 22 slides along the arc-shaped groove 18, the ball bearing 30 helps to reduce the friction force on the T-shaped slider 22.

[0046] Multiple movable blocks 21 are distributed sequentially from the first end to the last end, and a fixed block 20 is provided between the movable blocks 21 at the first end and the movable blocks 21 at the last end. The fixed block 20 is fixed on the outer circumference of the annular plate 14. A fixed wire guide block 33 is fixedly connected to the fixed block 20. The fixed wire guide block 33 is located on the inner circumference of the annular plate 14. Both the sliding wire guide block 31 and the fixed wire guide block 33 are provided with a wire guide hole for the copper wire to pass through. The axis of the wire guide hole is parallel to the axis of the annular plate 14.

[0047] Connectors are provided between adjacent movable blocks 21 and between the movable block 21 and the fixed block 20 at the beginning, from the first end to the last end.

[0048] The connecting component includes a first connecting rod 23 and a second connecting rod 25. Between the movable block 21 and the fixed block 20 at the beginning, one end of the first connecting rod 23 is rotatably mounted on the fixed block 20, and one end of the second connecting rod 25 is rotatably mounted on the movable block 21 at the beginning. Figure 4 As shown, in a counter-clockwise direction, the movable block 21 adjacent to the right side of the fixed block 20 is the beginning, and the movable block 21 adjacent to the left side of the fixed block 20 is the end. From the beginning to the end, between two adjacent movable blocks 21, one end of the first connecting rod 23 is rotatably mounted on the movable block 21 closer to the fixed block 20, and one end of the second connecting rod 25 is rotatably mounted on the other movable block 21. The end of the first connecting rod 23 away from the annular plate 14 is fixedly connected to a shaft 24, and the end of the second connecting rod 25 away from the annular plate 14 has a rotating hole 26 that rotatably engages with the shaft 24.

[0049] In this embodiment, servo motors 27 are mounted on both the fixed block 20 and the movable block 21. On the fixed block 20, the output shaft of the servo motor 27 is fixedly connected to the first connecting rod 23. On the movable block 21, the output shaft of the servo motor 27 is fixedly connected to the second connecting rod 25.

[0050] In this embodiment, except for the end movable block 21, each movable block 21 is equipped with a first connecting rod 23 and a second connecting rod 25, and the first connecting rod 23 and the second connecting rod 25 on the same movable block 21 are connected by a transmission. Specifically, the first connecting rod 23 and the second connecting rod 25 on the same movable block 21 are fixedly connected with gears 28, and the two gears 28 on the same movable block 21 mesh.

[0051] Based on the number of copper wires wound on the cable 12, a certain number of T-shaped sliders 22 are slid into the arc-shaped groove 18, so that the number of wire-passing holes on the inner circumference of the annular plate 14 is equal to the number of copper wires. Furthermore, the multiple wire-passing holes located on the inner circumference of the annular plate 14 are evenly distributed circumferentially along the axis of the annular plate 14, so that the copper wires can be evenly wound on the cable 12.

[0052] Working principle: such as Figure 4 As shown, initially, the T-shaped slider 22 is located within the T-shaped groove 15, and the movable block 21 is located at one end of the T-shaped groove 15 near the wiring mechanism. One end of the sliding block 31 is inserted into the corresponding limiting groove 16. At this time, due to the limiting effect of the T-shaped slider 22 and the limiting groove 16, the movable block 21 cannot move and is fixed relative to the annular plate 14. Adjacent movable blocks 21 are connected by a first connecting rod 23 and a second connecting rod 25. The first connecting rod 23 on the fixed block 20 and the second connecting rod 25 on the first movable block 21 are in a separated state. This occurs when the axis of the shaft 24 on the fixed block 20 is aligned with the axis of the corresponding rotating hole 26.

[0053] For ease of description, the position on the annular plate 14 corresponding to the arc-shaped through groove 17 is defined as the wire threading station. When the movable block 21 is in the wire threading station, the sliding wire guide block 31 passes through the arc-shaped through groove 17 and is located on the inner circumference of the annular plate 14. At this time, the copper wire can be passed through the wire guide hole on the sliding wire guide block 31. The fixed wire guide block 33 is located in the wire threading station.

[0054] In use, the number of sliding wire guide blocks 31 on the wiring device 10 is adjusted according to the number of copper wires to be wound on the cable 12, that is, the number of sliding wire guide blocks 31 located at the wire threading station is adjusted. Assuming the number of copper wires to be wound on the cable 12 is N, then the number of wire guide holes at the wire threading station should match the number of copper wires, i.e., N, and the N wire guide holes should be evenly distributed circumferentially along the axis of the annular plate 14. Since the fixed wire guide block 33 is fixed at the wire threading station, the number of sliding wire guide blocks 31 at the wire threading station should be N-1. That is, (N-1) movable blocks 21 need to be moved to the wire threading station. During adjustment, starting from the first end, (N-1) movable blocks 21 are moved to the wire threading station sequentially. For example, when the number of copper wires to be wound on the cable 12 is six, five movable blocks 21 need to be moved sequentially to the wire threading station starting from the first end.

[0055] Specifically, during adjustment, first move the movable block 21 at the beginning to the threading position. For example... Figure 4 As shown, the movable block 21 adjacent to the right side of the fixed block 20 is at the first end. When the movable block 21 at the first end is moved, the electric push rod 32 inside the movable block 21 at the first end is first shortened, so that the sliding guide block 31 at the first end is retracted into the movable block 21, and the sliding guide block 31 at the first end is disengaged from the limiting groove 16. Then, the T-shaped slider 22 at the first end is moved into the arc-shaped groove 18, and the sliding guide block 31 at the first end is aligned with the arc-shaped through groove 17. Then, the electric push rod 32 at the first end is extended, so that the sliding guide block 31 at the first end passes through the arc-shaped through groove 17 and extends to the inner circumference of the annular plate 14. During the movement of the movable block 21 at the first end toward the arc-shaped groove 18, the second connecting rod 25 on the movable block 21 at the first end moves toward the first connecting rod 23 on the fixed block 20, so that the first connecting rod 23 on the fixed block 20 and the second connecting rod 25 on the movable block 21 at the first end are connected by the shaft 24 and the rotating hole 26. As the movable block 21 moves, the first link 23 on the movable block 21 disengages from the corresponding second link 25. Because the servo motor 27 has a self-locking property, the first link 23 on the fixed block 20, as well as the second link 25 and the first link 23 on the movable block 21, cannot rotate. Since the movable block 21 at the beginning is connected to the fixed block 20 via the first link 23 and the second link 25, the movable block 21 at the beginning is fixed relative to the fixed block 20.

[0056] like Figure 4 As shown, following the counter-clockwise direction, the second movable block 21, which is adjacent to the first movable block 21, is moved to the threading station. After the second movable block 21 is moved to the threading station, it is connected to the first movable block 21 through a connector and then disconnected from the second movable block 21.

[0057] Therefore, in a counter-clockwise direction, move (N-1) movable blocks 21 to the threading station in sequence.

[0058] Of course, it is also possible to start from the beginning and move (N-1) movable blocks 21 to the threading station at the same time. Specifically, the corresponding sliding thread-passing block 31 is retracted into the movable block 21 by the electric push rod 32, and then (N-1) movable blocks 21 are moved at the same time, so that the corresponding T-shaped slider 22 moves into the arc groove 18 and the electric push rod 32 extends, so that the corresponding sliding thread-passing block 31 passes through the arc groove 17 and extends to the inner circumference of the annular plate 14.

[0059] like Figure 14 and Figure 15 The diagram shows the status of the five active blocks 21 located at the threading station.

[0060] Then, the servo motors 27 on the fixed block 20 and the movable block 21 located at the threading station are activated, causing the first connecting rod 23 and the second connecting rod 25 at the threading station to rotate. This causes the movable block 21 to slide along the arc-shaped through groove 17, and the corresponding T-shaped slider 22 to slide within the arc-shaped groove 18. The distance between the fixed block 20 and the first movable block 21, as well as between adjacent movable blocks 21, increases, and the included angle between the first connecting rod 23 and the second connecting rod 25 gradually increases.

[0061] When the servo motor 27 rotates to a certain angle, it stops. At this time, the five movable blocks 21 and fixed blocks 20 located at the wire threading station are evenly distributed along the circumference of the annular plate 14. That is, at this time, the N wire-passing holes in the annular plate 14 are evenly distributed along the circumference of the annular plate 14, so that the N copper wires are evenly distributed according to the straight circumference of the rotating drum 2, which is beneficial to make the copper wires evenly wound onto the cable 12.

[0062] like Figure 16 , Figure 17 and Figure 18 As shown, this is a schematic diagram of a structure in which six wire holes are evenly distributed along the circumference of the annular plate 14, i.e., five movable blocks 21 and fixed blocks 20 are evenly distributed along the circumference of the annular plate 14.

[0063] It should be noted that the relationship between the rotation angle of the servo motor 27 and N can be measured in advance. The angle that the servo motor 27 needs to rotate when the N wire holes are evenly distributed on the inner circumference of the annular plate 14 can be measured or calculated in advance.

[0064] Because the servo motor 27 has a self-locking property, the first link 23 and the second link 25 will not rotate unexpectedly, thereby keeping the movable block 21 and the fixed block 20 on the threading station evenly distributed along the circumference of the annular plate 14.

[0065] Next, the electromagnet 29 on the movable block 21 at the threading station is activated, causing the T-shaped slider 22 to be attracted to the iron sheet 19. This fixes the movable block 21 at the threading station onto the annular plate 14, making the movable block 21 at the threading station more stable.

[0066] When moving the five movable blocks 21 toward the threading station, the sliding wire-passing blocks 31 in the five movable blocks 21 can also be dislodged from the corresponding limiting grooves 16, and then the five movable blocks 21 can be moved toward the threading station at the same time.

[0067] Next, one end of the copper wire on the copper wire coil 8 is wrapped around the corresponding wire guide wheel 9 and passed through the corresponding wire guide hole, and then fixed to the cable 12. The motor 4 is started, the drum 2 rotates, and the drum 2 drives the turntable 6 and the wiring device 10 to rotate, so that the copper wire is gradually and evenly wound on the cable 12.

[0068] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
