Description

Technical Field

[0001] The invention relates to the technical field of power cable processing, and in particular to an automatic wire twisting device for manufacturing power cables. Background Art

[0002] Automated wire twisting processing usually allows two or more single wires to form an interlaced state in a predetermined direction (counterclockwise or clockwise). The form can be regular twisting or irregular twisting. Simply put, twisting is the twisting of single wires. The twisting process includes conductor twisting, cabling, braiding, wire armoring and winding.

[0003] According to the publication number "CN116313303A", an automatic wire twisting equipment for power cable manufacturing includes: a fixed base, on the top of which are installed a first support, a second support, and a third support arranged in sequence along its length direction, and a fixed cover is fixedly connected to the first support.

[0004] Although the prior art solves the problem of the conductor being worn due to the shaking caused by the rotational force under the action of its own gravity, the conductor may also be separated from the roller that receives the conductor during the shaking process. However, when the twisted wires are processed in the factory, the twisted wires and single conductors will be disturbed by external flying dust, which will cause the twisted wires to not be able to stick close to each other when twisted. Therefore, the finished cables are prone to breakage due to uneven force. Summary of the invention

[0005] The purpose of the present invention is to solve the following shortcomings in the prior art: when the wire twisting process is carried out in the factory, the twisted wires and single conductors will be disturbed by external flying dust, resulting in the twisted wires not being able to fit tightly against each other during twisting. Therefore, the finished cables are prone to breakage due to uneven force. An automated wire twisting equipment for power cable manufacturing is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: An automatic twisting device for manufacturing power cables, comprising a base, a protective cavity, a pushing component and a limiting component, wherein the protective cavity is fixedly connected to the base, a first turntable is rotatably connected in the protective cavity, two L-shaped fixed frames are fixedly connected to the first turntable, a sleeve is fixedly connected between the two fixed frames, a conductor is arranged in the sleeve, and a plurality of rotating rods are rotatably connected to the first turntable; The pushing component includes an arc block, a first spring, a cleaning component and a pneumatic component. The two arc blocks are slidably connected between the sleeves. Slide grooves are respectively provided on both sides of the sleeve. A plurality of the first springs are fixedly connected between the inner side wall of the sleeve end and the arc block. Both ends of the arc block are respectively fixedly connected with a transverse plate, which is slidably connected in the slide groove. The pushing component is used to limit the outer surface of the wire and clean it. The limiting component includes two discs, an airbag and a pneumatic assembly, wherein one of the discs is fixedly connected to the inner wall of the sleeve, and the other disc is slidably connected to the inner wall of the sleeve. The airbag is fixedly connected between the two discs, and the airbag is arranged in an arc shape. The limiting component is used to limit the winding wire in the automated wire twisting process of power cable manufacturing.

[0007] Preferably, the cleaning assembly includes a rotating shaft, a screw, a rack plate, a hinged rod, and a protrusion. The multiple screws are divided into two groups, each group has two screws, the two groups of screws are respectively threadedly connected between two horizontal plates located on both sides of the sleeve, the outer surface of the middle part of the screw is provided with teeth, the rotating shaft is rotatably connected between the two fixed frames, the two protrusions are respectively fixedly connected to both ends of the rotating shaft, the two rack plates are respectively arranged between the two horizontal plates and between the two screws, the two sides of the rack plate are respectively meshed with the screws, and the hinged rod is hinged between the protrusion and the end of the rack plate.

[0008] Preferably, the pneumatic assembly includes a straight cylinder, a movable rod, a cleaning cylinder, and an air collecting chamber. A plurality of through grooves are provided on the side wall of the sleeve. A plurality of the straight cylinders are arranged in a circular array on one of the discs. One end of the movable rod is slidably connected in the straight cylinder. The air collecting chamber is fixedly connected to the end of the movable rod away from the straight cylinder. The cleaning cylinder is fixedly connected to one side of the air collecting chamber. An exhaust port is provided on the inner wall of the air collecting chamber.

[0010] Preferably, a second spring is fixedly connected between the transverse plates located on both sides of the same rack plate, and a limiting block is fixedly connected to one end of the two rack plates away from the hinge rod.

[0011] Preferably, a third spring is fixedly connected between two opposite inner side walls of the airbag, a push rod is slidably connected to one of the discs, and one end of the push rod is fixedly connected to the inner side wall of the right end of the airbag.

[0017] At the same time, as the rack plate moves to the right, the limit block can limit the screw and drive the cross plate and the arc block to move to the right, so as to clean the attachments on the outer surface of the wire and prevent the twisted wire and the single wire from being disturbed by external flying dust, resulting in the twisted wires not being able to stick close to each other when twisted. Therefore, the finished cable is prone to breakage due to uneven force. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-Figure 9 , an automatic wire twisting equipment for power cable manufacturing includes a base 1, a protective cavity 4, a pushing component and a limiting component. The protective cavity 4 is fixedly connected to the base 1, and a first turntable 5 is rotatably connected in the protective cavity 4. Two L-shaped fixed frames 2 are fixedly connected to the first turntable 5, and a sleeve 6 is fixedly connected between the two fixed frames 2. A wire 30 is arranged in the sleeve 6, and the wire 30 passes through the first turntable 5, the second turntable 7 and the axial center line of the sleeve 6, and moves continuously to the left under the pull of an external machine. A plurality of rotating rods 3 are rotatably connected to the first turntable 5, and the plurality of rotating rods 3 are arranged in a ring array on the first turntable 5. Each twisted wire can slide on the rotating rod 3 and slide on the second turntable 7 to complete the winding of the wire 30. Since the second turntable 7 is smaller than the first turntable 5, the plurality of twisted wires can be arranged in a cone shape to the left from the first turntable 5, and the second turntable 7 can have a limiting effect on the twisted wires.

[0022] The pushing component includes an arc block 11, a first spring 18, a cleaning component and an air pressure component. The two arc blocks 11 are slidably connected between the sleeve 6 and are symmetrically arranged with the wire 30 as the axis. Slide grooves are respectively provided on both sides of the sleeve 6, and the slide grooves are used for the sliding of the cross plate 12. Multiple first springs 18 are fixedly connected between the inner side wall of the end of the sleeve 6 and the arc block 11. The first spring 18 always has a pulling force to the right on the arc block 11. Therefore, when the rack plate 13 moves to the left, the first spring 18 has a pulling force on the arc block 11 to form a resistance, so that the rack plate 13 moves, which can drive the screws 20 on both sides to rotate. When the screw 20 rotates, it can drive the cross plates 12 on both sides to move away from each other, thereby driving the two arc blocks 11 to move away from each other and no longer fit the wire 30. The two ends of the arc block 11 are respectively fixedly connected with the cross plates 12, and the cross plates 12 are slidably connected in the slide groove. The pushing component is used to limit and clean the outer surface of the wire 30.

[0023] The cleaning assembly includes a rotating shaft 14, a screw rod 20, a rack plate 13, a hinge rod 15, and a protrusion 17. The plurality of screw rods 20 are divided into two groups, each group of screw rods 20 has two screw rods 20, and the two groups of screw rods 20 are respectively threadedly connected between the two transverse plates 12 located on both sides of the sleeve 6. The outer surface of the middle part of the screw rod 20 is provided with a tooth pattern. The rotating shaft 14 is rotatably connected between the two fixing frames 2. The two protrusions 17 are respectively fixedly connected to the two ends of the rotating shaft 14. The two rack plates 13 are respectively arranged between the two transverse plates 12 and between the two screw rods 20. The two sides of the rack plate 13 are respectively meshed with the screw rods 20, so that the movement of the rack plate 13 can rotate the screw rod 20. When the rack plate 13 moves to the left, it can drive the two arc blocks 11 away from each other. When the rack plate 13 moves to the right, it can drive the two arc blocks 11 closer to each other. The hinge rod 15 is hinged between the protrusion 17 and the end of the rack plate 13. The pneumatic assembly includes a straight cylinder 9, a moving rod 27, a cleaning cylinder 28, and an air collecting chamber 29. A plurality of through grooves are provided on the side wall of the sleeve 6, and the plurality of through grooves are used for the left and right sliding of the straight cylinder 9. The plurality of straight cylinders 9 are arranged in a circular array on one of the disks 21. One end of the moving rod 27 is slidably connected in the straight cylinder 9, and the outer wall of the moving rod 27 is sealed and slides on the inner wall of the straight cylinder 9, so that when the moving rod 27 moves downward rapidly, the gas in the straight cylinder 9 can be pressurized and enter the air collecting chamber 29. The air collecting chamber 29 is fixedly connected to the end of the moving rod 27 away from the straight cylinder 9. Therefore, when the moving rod 27 moves downward in the straight cylinder 9, the gas in the straight cylinder 9 can be squeezed and transmitted to the air collecting chamber 29 through the moving rod 27. The cleaning cylinder 28 is fixedly connected to one side of the air collecting chamber 29, and an exhaust port is provided on the inner wall of the air collecting chamber 29. The gas entering the air collecting chamber 29 is discharged to the twisted wire through the exhaust port.

[0024] The limiting component includes two discs 21, an airbag 10 and a pneumatic assembly, wherein one disc 21 is fixedly connected to the inner wall of the sleeve 6, and the other disc 21 is slidably connected to the inner wall of the sleeve 6. The disc 21 on the left is fixed in the sleeve 6, and the disc 21 on the right is slidably connected to the inner wall of the sleeve 6. The airbag 10 is fixedly connected between the two discs 21. The airbag 10 is arranged in an arc shape. The limiting component is used to limit the winding wire in the process of automatic twisting of power cable manufacturing. A third spring 22 is fixedly connected between the two opposite inner walls of the airbag 10, and a push rod 24 is slidably connected to one of the discs 21. The push rod 2 One end of the push rod 24 is fixedly connected to the inner wall of the right end of the airbag 10, and the end of the push rod 24 away from the disc 21 is fixedly connected to the knocking block 23. The inner wall of the sleeve 6 is fixedly connected to the impact block 26. The knocking block 23 is arranged between the impact blocks 26. When the disc 21 located on the right side moves to the left and squeezes the third spring 22, the disc 21 can push the push rod 24 to move. When the push rod 24 moves to the left, the knocking block 23 can hit the impact block 26, which vibrates the sleeve 6, so that the dust located in the sleeve 6 can be shaken off and discharged through the discharge port. A plurality of discharge ports are opened on the side wall of the sleeve 6, and the discharge ports are arranged on the lower side of the airbag 10.

[0025] A mounting block 8 is fixedly connected to the base 1, and a second turntable 7 is rotatably connected inside the mounting block 8. The second turntable 7 is provided with a plurality of threading holes. One end of the sleeve 6 away from the protective cavity 4 is fixedly connected to one side of the second turntable 7. The diameter of the first turntable 5 is larger than the diameter of the second turntable 7. Therefore, the twisted wire between the second turntable 7 and the first turntable 5 is arranged at an angle, so that the twisted wire is lower on the left and higher on the right.

[0026] In the present invention, when in use, first by the attached Figure 2 As shown, the wire 30 passes through the first rotating disk 5 and the second rotating disk 7 respectively, so when the first rotating disk 5 rotates, the sleeve 6 can be driven to rotate through the fixing frame 2, thereby driving the second rotating disk 7 to rotate. Fig. 9 As shown, multiple twisted wires slide on the rotating rod 3 respectively and pass through the cleaning cylinder 28 and the second turntable 7, and are connected to the wire 30. Since the wire 30 does not rotate, but only moves continuously to the left, it can pull one end of the multiple twisted wires to move to the left at the same time. Therefore, through the rotation of the first turntable 5 and the second turntable 7, the multiple twisted wires can be driven to be continuously wound around the wire 30.

[0027] Since the roller 16 is arranged on the wire 30, the roller 16 can be driven to rotate counterclockwise when the wire 30 moves continuously to the left. When the protrusion 17 rotates counterclockwise with the roller 16 through the rotating shaft 14, the protrusion 17 pushes the rack plate 13 to move back and forth horizontally through the hinge rod 15. When the rack plate 13 moves to the left, it can drive the screws 20 on both sides to rotate. When the screws 20 rotate, they can drive the cross plates 12 on both sides to move away from each other, thereby driving the two arc blocks 11 to move away from each other and no longer fit the wire 30. At this time, the cross plate 12 is limited by the rack plate 13. As the rack plate 13 and the arc block 11 move to the left and stretch the first spring 18, the arc block 11 squeezes the disc 21 on the right to move to the left. As one of the discs 21 moves to the left, it can squeeze the airbag 10, and the gas inside the airbag 10 is discharged and the dust on the outer surface of the wire 30 is blown away.

[0028] At the same time, as the disc 21 on the right side moves to the left and squeezes the third spring 22, the disc 21 can push the push rod 24 to move, and the knocking block 23 can hit the impact block 26 as the push rod 24 moves to the left, causing vibration to the sleeve 6, making it easier to shake off the dust located in the sleeve 6 and discharge it through the discharge port.

[0029] Since a plurality of twisted wires pass through the cleaning cylinder 28 respectively, and since the straight cylinder 9 is arranged on the disc 21, when the cleaning cylinder 28 moves to the left along with the disc 21 through the moving rod 27 and the straight cylinder 9, the cleaning cylinder 28 can scrape off and clean the larger adhesions attached to the surface of the twisted wires. At the same time, the first rotating disk 5 is larger than the second rotating disk 7, so the twisted wires between the first rotating disk 5 and the second rotating disk 7 are arranged obliquely. Fig. 9 As shown, the twisted wire is arranged upward from left to right at an angle, so when the cleaning cylinder 28 moves to the left, it is limited by the twisted wire, thereby pushing the moving rod 27 to move downward in the straight cylinder 9, and squeezing the gas in the straight cylinder 9 to be transmitted to the gas collecting chamber 29 through the moving rod 27, and discharged to the twisted wire through the exhaust port on the gas collecting chamber 29, which can blow off the fine dust that has not been scraped off by the cleaning cylinder 28.

[0030] At the same time, as the rotation of the roller 16 can drive the protrusion 17 to flip through the rotating shaft 14, the protrusion 17 pulls the rack plate 13 to move to the right through the hinge rod 15, and drives the screws 20 on both sides to rotate in the opposite direction, thereby driving the cross plates 12 on both sides to move in the middle. At this time, the arc blocks 11 on both sides of the conductor 30 move in the middle with the cross plates 12 and fit the conductor 30. At the same time, as the rack plate 13 moves to the right, the limit block 25 can limit the screw 20 and drive the cross plate 12 and the arc block 11 to move to the right, which can clean the attachments on the outer surface of the conductor 30, avoid the interference of the twisted wire and the single wire by the external flying dust, resulting in the twisted wires not being able to fit each other tightly when twisted, so the finished cable is prone to breakage due to uneven force.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
