Description

Technical Field

[0001] The invention relates to the technical field of cable production, in particular to a cable stranding machine and a stranding method thereof. Background Art

[0002] Cable is an electric energy or signal transmission device, usually composed of several or several groups of wires. Wire stranding machine is a kind of mechanical equipment that can be widely used for twisting various soft and hard conductor wires, so that multiple single conductors can be twisted into one strand to meet the process requirements of wire. Wire stranding machine is an important cable production equipment, including stranding drum and cabling equipment. During production, multiple strands of cables are passed through multiple through holes on the upper edge of the stranding drum. As the stranding drum rotates, the multiple strands of cables passing through multiple through holes are twisted into one cable.

[0003] During the cable twisting process, the cable may break due to various reasons, such as cable material defects, if there are a lot of impurities attached to the cable surface, such as dust, metal chips, oil, etc., the lead wheel will wear after long-term use, and the worn wheel surface may become uneven, with burrs or grooves. These reasons can easily cause the cable to break during the twisting process. When the cable breaks, due to the energy accumulated during the high-speed operation, it will generate a huge rebound force, which makes it very easy for the cable to splash out of the equipment after breaking, which may cause the cable to be entangled in the machine, damaging the internal structure of the equipment, seriously affecting the normal operation of the equipment, and increasing maintenance costs. At the same time, the splashing cable also poses a serious safety threat to people working near the equipment, which may cause personal injury. Summary of the invention

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example:

[0043] See also Figure 1-Figure 8 The present invention provides a technical solution: a cable stranding machine, including a base plate 1, on which a motor 2, a conductor frame 4, a wire dividing wheel 5, a wire lead wheel 6 and a die 7 are arranged, the output shaft of the motor 2 is fixedly installed with a rotating shaft 3, the rotating shaft 3 passes through the conductor frame 4, the wire dividing wheel 5 and the wire lead wheel 6 respectively, and the rotating shaft 3 can drive the conductor frame 4, the wire dividing wheel 5 and the wire lead wheel 6 to rotate, and at the same time, gears are fixedly installed on the motor 2 and the rotating shaft 3, and the two gears are meshed and connected, the motor 2 can drive the rotating shaft 3 to rotate through the gears, thereby completing the cable stranding, the conductor frame 4 is provided with a cable 8, and the cable 8 passes through the wire dividing wheel 5 and the wire lead wheel 6 respectively The cables are twisted into a cable in a parallel mold 7, and a through hole 9 is evenly penetrated at a medium angle on the branch wheel 5. A first connecting frame 10 and a second connecting frame 12 are respectively arranged in the through hole 9. A fixed wheel 15 is arranged below the first connecting frame 10, and a movable wheel 14 is arranged above the second connecting frame 12. The cable 8 is located between the fixed wheel 15 and the movable wheel 14. A reverse limiting mechanism is arranged in the first connecting frame 10, and the reverse limiting mechanism includes a stabilizing frame 19. When the cable 8 breaks and returns, the fixed wheel 15 instantly reverses and triggers the stabilizing frame 19 in the reverse limiting mechanism to move downward. When the stabilizing frame 19 moves downward, it forms a U-shape with the two movable wheels 14 to block the cable 8 from splashing out of the branch wheel 5.

[0044] In this embodiment, sliding rods 13 are fixedly installed on the outer sides of the first connecting frame 10 and the second connecting frame 12, and a sliding cavity matching the sliding rod 13 is opened on the inner wall of the through hole 9. A telescopic cylinder 11 is fixedly installed on the outer side of the wire dividing wheel 5, and the output shaft end of the telescopic cylinder 11 is fixedly connected to the first connecting frame 10. The telescopic cylinder 11 can drive the first connecting frame 10 and the second connecting frame 12 to slide in the through hole 9 through the sliding rod 13, so that the position of the cable 8 in the through hole 9 can be changed, that is, the folding angle of the cable 8 between the wire dividing wheel 5 and the wire rack 4 can be adjusted, and the folding angle of the cable 8 between the wire dividing wheel 5 and the lead wheel 6 can be adjusted.

[0045] The sliding rod 13 slides in the sliding cavity, which can drive the first connecting frame 10 and the second connecting frame 12 to slide in the through hole 9. At the same time, the sliding rod 13 can ensure the stability of the first connecting frame 10 and the second connecting frame 12 when sliding in the through hole 9, and prevent the first connecting frame 10 and the second connecting frame 12 from detaching from the through hole 9.

[0046] The first connection frame 10 and the second connection frame 12 provided in the wire splitting wheel 5 can adjust the bending angle of the cable 8 between the wire splitting wheel and the conductor frame and between the wire splitting wheel and the lead wheel, so that the cable can be flexibly adjusted in position in different working scenarios to adapt to different twisting requirements.

[0047] In this embodiment, the reverse limiting mechanism also includes a first rotating column 16 and a first pushing block 18. The first rotating column 16 is movably installed with a transmission belt 17, and a rotating gear 22 is fixedly installed on the outer side of the first rotating column 16. The outer side of the rotating center axis of the fixed wheel 15 is movably connected to the transmission belt 17. When the fixed wheel 15 rotates, the first rotating column 16 is driven to rotate together through the transmission belt 17, and the rotating gear 22 is driven to rotate together, thereby ensuring that the cable 8 will not be hindered when moving toward the side of the lead wheel 6.

[0048] In this embodiment, a rack plate 23 is provided in the first connecting frame 10, and the rack plate 23 is movably installed on the inner wall of the first connecting frame 10. The rotating gear 22 is meshed and connected with the rack plate 23. When the rotating gear 22 rotates, it can drive the rack plate 23 to move. A second push block 24 is fixedly installed at one end of the rack plate 23. The second push block 24 is in sliding contact with the first push block 18, and matching inclined surfaces are provided between the first push block 18 and the second push block 24. The bottom end of the first push block 18 is fixedly connected to the stabilizing frame 19. When the rack plate 23 moves, the second push block 24 can be driven to move horizontally. When the second push block 24 moves, the second push block 18 can be driven to move downward through the inclined surface and extend out of the first connecting frame 10. A limiting column is fixedly installed inside the first connecting frame 10. The limiting column passes through the side of the second push block 18, and a buffer spring is provided on the outside of the limiting column. The buffer spring can enable the first push block 18 to remain inside the first connecting frame 10 when it is not pushed by the second push block 24.

[0049] In this embodiment, a rotating wheel 25 is movably installed on the outer side of the fixed wheel 15, and a transmission belt 17 is arranged on the outer side of the rotating wheel 25. The outer side of the rotating wheel 25 is movably connected with the transmission belt 17. A tooth block is arranged on the outer side of the rotating center axis of the fixed wheel 15, and a limiting column is also arranged on the inner ring side of the rotating wheel 25. The limiting column can be extended and retracted in the rotating wheel 25. When the tooth block moves in the normal working direction of the cable 8, the limiting column and the tooth block are not in contact. When the cable 8 moves in the opposite direction, the limiting column will contact the tooth block. When the fixed wheel 15 rotates, it will drive the rotating wheel 25 to rotate together, and through the action of the transmission belt 17 and the first rotating column 16, the rotating gear 22 will also reverse. The rotating gear 22 will drive the rack plate 23 to move under the action of the limiting block, and can drive the first pushing block 18 to move through the second pushing block 24, to ensure that the rack plate 23 will not affect the cable 8 passing through the fixed wheel 15 and the movable wheel 14 when the cable 8 is in normal use.

[0050] During use, when the cable 8 breaks, the cable 8 will drive the fixed wheel 15 to reverse. After the fixed wheel 15 reverses, it will drive the rotating gear 22 to reverse through the transmission belt 17 and the first rotating column 16. After the rotating gear 22 reverses, it will drive the rack plate 23 to move through the cooperation of the upper limit block of the rack plate 23. When the rack plate 23 moves, it will drive the first pushing block 18 to move downward through the second pushing block 24 and the inclined surface. When the first pushing block 18 moves downward, it will drive the stabilizing frame 19 to move downward. At the same time, when the stabilizing frame 19 moves downward, it will drive the cable 8 to contact the two movable wheels 14 under the cable 8, and make the stabilizing frame 19 and the two movable wheels 14 form a U shape. At the same time, the cable 8 will also form a U shape here, ensuring that the cable 8 will not splash out from the line dividing wheel 5, preventing the cable 8 from being entangled in the machine under the huge rebound force after breaking, and preventing the cable 8 from injuring the staff when rebounding.

[0051] See also Fig. 9 The present invention provides a technical solution: in this embodiment, a fixing column 26 is fixedly installed in the stabilizing frame 19, and a clamping plate 21 and an extrusion spring 27 are respectively provided on the outer sides of the fixing column 26. Both sides of the top of the clamping plate 21 are fixedly connected to the extrusion spring 27. At the same time, the extrusion spring 27 does not contact the surface of the cable 8, and the cable 8 passes between two adjacent clamping plates 21.

[0052] When the cable 8 is in use, it passes between two adjacent groups of fixed wheels 15 and the movable wheel 14 and passes through the stabilizing frame 19. The clamping plate 21 in the stabilizing frame 19 contacts the cable 8. At the same time, a cleaning plate is provided on the contact side of the clamping plate 21 and the cable 8. The cleaning plate can clean the surface of the cable 8 in contact with it, reduce impurities attached to the cable 8, and reduce the risk of cable 8 breaking. At the same time, the cable 8 will squeeze the extrusion spring 27 when passing through the clamping plate 21. Since the extrusion spring 27 has a buffering function, it can avoid a large offset distance of the cable 8 when rotating between the two adjacent groups of fixed wheels 15 and the movable wheel 14, avoid the cable 8 from contacting the right-angle edge of the dividing wheel 5, and reduce the risk of cable 8 breaking.

[0053] See also Figure 10-12 The present invention provides a technical solution: in this embodiment, an auxiliary extrusion mechanism is provided in the second connecting frame 12, and the auxiliary extrusion mechanism includes a contact frame 20 and a connecting rod 28. The top end of the connecting rod 28 is fixedly connected to the movable wheel 14, and the bottom ends of the contact frame 20 and the connecting rod 28 both extend into the second connecting frame 12. A sliding plate 32 is fixedly installed at the bottom end of the contact frame 20, and a piston plate 31 is fixedly installed at the bottom end of the connecting rod 28. When the contact frame 20 moves downward, it will drive the connecting rods 28 and the movable wheel 14 on both sides to move upward, thereby further squeezing the cable 8 with the stabilizing frame 19 to prevent the cable 8 from splashing.

[0054] In this embodiment, a fixed frame 29 and a partition 30 are fixedly installed in the second connecting frame 12, respectively. The sliding plate 32 extends into the fixed frame 29, and a sliding groove 33 matching the sliding plate 32 is opened in the fixed frame 29. A piston block 34 is arranged under the sliding plate 32, and a connecting channel 35 is arranged between the fixed frame 29 and the partition 30. When the piston block 34 moves downward, the connecting channel 35 causes the piston plate 31 on one side of the partition 30 to move upward.

[0055] The upper surface of the contact frame 20 is also provided with a cleaning plate to clean the lower surface of the cable 8 .

[0056] When the cable 8 breaks, the stabilizing frame 19 moves downward to drive the cable 8 to form a U shape. At the same time, the stabilizing frame 19 will contact the contact frame 20 during the downward movement, and drive the contact frame 20 to move toward the second connecting frame 12. When the contact frame 20 moves downward, it will drive the sliding plate 32 to slide in the sliding groove 33 in the fixed frame 29. At the same time, when the sliding plate 32 slides, the piston block 34 will push the gas in the fixed frame 29 to one side of the partition 30 through the connecting channel 35, and will drive the movable wheel 14 to move upward through the piston plate 31 and the connecting rod 28. The two movable wheels 14 will further lock the cable 8 with the stabilizing frame 19, further preventing the cable 8 from being entangled with the machine under the action of the huge rebound force and accidentally injuring the staff near the machine.

[0057] When encountering cables 8 of different diameters at the same time, when the cable 8 passes between the fixed wheel 15 and the movable wheel 14, the movable wheel 14 will move downward, and the sliding plate 32 will drive the contact frame 20 to move upward for a certain distance, so that the wire dividing wheel 5 can adapt to cables 8 of different diameters, which is convenient for the twisting of the cables.

[0058] A cable stranding method for a cable stranding machine comprises the following steps:

[0059] Step 1: During operation, the cable 8 is separated from the conductor frame 4 and passed through the wire separation wheel 5 and the wire lead wheel 6 and twisted into a finished cable in the combining mold 7;

[0060] Step 2: The cable 8 is located between the fixed wheel 15 and the movable wheel 14 in the cable splitting wheel 5, and slides through between the movable wheel 14 and the fixed wheel 15. A stabilizing frame 19 is provided between two adjacent fixed wheels 15, and a clamping plate 21 is provided in the stabilizing frame 19 to prevent the cable 8 from shaking greatly between the fixed wheel 15 and the movable wheel 14;

[0061] Step 3: When the cable 8 is broken, the fixed wheel 15 and the movable wheel 14 will be driven to reverse together. When the fixed wheel 15 is reversed, the stabilizing frame 19 will be driven to move downward through the reverse limiting mechanism. When the stabilizing frame 19 moves downward, the cable 8 below it will be driven to move downward together. Through the cooperation of the two movable wheels 14, the cable 8 below the stabilizing frame 19 forms a U shape to prevent the cable 8 from splashing.

[0062] Step 4: When the stabilizing frame 19 moves downward, it will drive the contact frame 20 to extend into the second connecting frame 12 , and the auxiliary extrusion mechanism in the second connecting frame 12 will drive the movable wheel 14 to move upward, forming a U shape with the stabilizing frame 19 , further strengthening the fixation of the cable 8 .

[0063] The working principle of this embodiment is as follows: when the cable 8 breaks, the cable 8 will drive the fixed wheel 15 to reverse. After the fixed wheel 15 reverses, it will drive the rotating gear 22 to reverse through the transmission belt 17 and the first rotating column 16. After the rotating gear 22 reverses, it will drive the rack plate 23 to move through the cooperation of the upper limit block of the rack plate 23. When the rack plate 23 moves, it will drive the first pushing block 18 to move downward through the second pushing block 24 and the inclined surface. When the first pushing block 18 moves downward, it will drive the stabilizing frame 19 to move downward. At the same time, when the stabilizing frame 19 moves downward, it will drive the cable 8 to contact the two movable wheels 14 below the cable 8, and make the stabilizing frame 19 and the two movable wheels 14 form a U shape. At the same time, the cable 8 will also form a U shape here, ensuring that the cable 8 will not splash out from the line dividing wheel 5, preventing the cable 8 from being entangled in the machine under the huge rebound force after breaking, and preventing the cable 8 from injuring the staff when rebounding.

[0064] When the cable 8 passes through the clamping plate 21, the extrusion spring 27 is squeezed. Since the extrusion spring 27 has a buffering function, it can prevent the cable 8 from being offset by a large distance when rotating between two adjacent sets of fixed wheels 15 and movable wheels 14, and avoid the cable 8 from contacting the right-angled edge of the dividing wheel 5, thereby reducing the risk of the cable 8 breaking.

[0065] The downward movement of the stabilizing frame 19 drives the cable 8 to form a U shape. At the same time, the stabilizing frame 19 will contact the contact frame 20 during the downward movement, and drive the contact frame 20 to move toward the second connecting frame 12. When the contact frame 20 moves downward, it will drive the sliding plate 32 to slide in the sliding groove 33 in the fixed frame 29. At the same time, when the sliding plate 32 slides, the piston block 34 will push the gas in the fixed frame 29 to one side of the partition 30 through the connecting channel 35, and will drive the movable wheel 14 to move upward through the piston plate 31 and the connecting rod 28. The two movable wheels 14 will further lock the cable 8 with the stabilizing frame 19, further preventing the cable 8 from being entangled in the machine under the action of the huge rebound force and accidentally injuring the staff near the machine.

[0066] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
