Description

Technical Field

[0001] The present invention belongs to the technical field of cable stranding, and specifically relates to a cable stranding machine. Background Art

[0002] A cable stranding machine, also known as a cable twisting machine, is a key device used to twist multiple insulated wires or bare wires into a cable according to certain rules during cable manufacturing. Such devices can ensure that the twisted cable has good physical stability and electrical performance.

[0003] The patent with the publication number CN209015778U discloses a cable stranding machine, which includes a wire rotating mechanism. One end of a rotating shaft is fixedly connected to the wire rotating mechanism, and the other end fixedly passes through a protective wire rotating mechanism and is fixedly connected to a guiding disk. A driving component is arranged at one end of the rotating shaft. A number of guiding holes are circumferentially and evenly distributed on the guiding disk. The inside of the rotating shaft is hollow and is respectively provided with an inlet through which the wire penetrates and a number of outlet holes near the wire rotating mechanism and near the guiding disk. The protective wire rotating mechanism includes a large turntable and a small turntable. Three groups of perforations are equiangularly arranged on the small turntable. In this solution, a number of mounting rods are fixed on the small turntable, so that a number of small coil protective wire reels can be installed, enabling the protective wire rotating mechanism to twist more strands of protective wire, so as to select different numbers of strands of protective wire according to cable requirements and improve the versatility of the protective wire rotating mechanism.

[0004] In the above solution, when the cable is being twisted, the protective wire will sequentially pass through the perforations on the small turntable and the guiding holes on the guiding disk. Since the protective wire is twisted onto the wire, the protective wire cannot move along the central axes of the perforations and the guiding holes, resulting in friction between the inner walls of the perforations and the guiding holes and the protective wire. The friction will cause wear of the protective wire and affect the cable quality. Therefore, the present invention provides a cable stranding machine. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A cable stranding machine of the present invention includes a wire placement rack, on which a wire mounting roller is rotatably installed. One end of the wire placement rack is rotatably connected to a wire tube. A first gear, a protective wire placement disk, a guiding disk, and a stranding disk are sequentially and fixedly sleeved on the wire tube. A die head is placed directly in front of the wire tube. The first gear meshes with a second gear, and the end of the second gear is rotatably connected to the wire placement rack. Six groups of protective wire mounting rollers are rotatably installed at equal angles on the protective wire placement disk. An oil tank is arranged directly below the guiding disk. Six groups of mounting grooves are equiangularly arranged on the guiding disk, and four groups of wire wheels are rotatably installed in the mounting grooves. Six groups of perforations are equiangularly arranged on the stranding disk;

[0007] By driving the guide disk to rotate, the wire wheels in the six groups of mounting grooves on the guide disk can successively come into contact with the lubricating oil in the fuel tank. The wire wheels attached with lubricating oil apply lubricating oil to the protective wire, realizing the lubrication of the protective wire, reducing the friction between the wire wheels, the perforations and the protective wire, thereby greatly reducing the wear of the protective wire and improving the quality of cable manufacturing.

[0008] Preferably, an oil-smearing mechanism is arranged in the fuel tank. The oil-smearing mechanism includes a transmission shaft, the transmission shaft is rotationally connected to the fuel tank, a third gear is fixedly sleeved at one end of the transmission shaft, a fourth gear meshing with the third gear, an oil-smearing disk, the oil-smearing disk is fixedly installed at the other end of the transmission shaft, six groups of sponges are equally-angularly installed on the outer ring of the oil-smearing disk, the fourth gear is fixedly sleeved on the stranding disk, the oil-smearing disk is located in the fuel tank and is directly below the guide disk;

[0009] The three groups of sponges successively and circularly come into contact with the lubricating oil in the fuel tank, enabling the sponges to absorb a certain amount of lubricating oil. When the sponge after absorbing lubricating oil rotates to the uppermost end of the oil-smearing disk, it will be squeezed by the lowest row of wire wheels on the guide disk, and the lubricating oil extruded from the sponge will adhere to the wire wheels, thereby realizing the application of lubricating oil to the protective wire by the above-mentioned wire wheels. Since the extrusion force of the wire wheels on the sponge is limited, the amount of lubricating oil extruded from the sponge is relatively small, and a small amount of lubricating oil adheres to the wire wheels, thus avoiding excessive lubricating oil being applied to the protective wire.

[0010] Preferably, the oil-smearing disk includes a disk body, the disk body is fixedly sleeved at the other end of the transmission shaft, six groups of movable grooves are equally-angularly arranged on the outer ring of the disk body, two groups of L-shaped clamping plates symmetrically arranged in the movable grooves, a support plate arranged between the two groups of L-shaped clamping plates, the sponge is fixedly installed on the support plate, a movable rod fixedly connected to the support plate, a spring sleeved on the movable rod, a receiving rod fixedly connected to the end of the movable rod, a slide rail is arranged in the movable groove, a guiding groove is opened at the bottom of the L-shaped clamping plate, the guiding groove is slidably connected to the slide rail, the receiving rod passes through the slide rail and extends into the inner cavity of the disk body, one end of the spring is fixedly connected to the end of the movable rod, the other end of the spring is fixedly connected to the inner wall of the disk body, an avoidance groove is opened on the L-shaped clamping plate, receiving plates are arranged on both sides of the support plate, one end of the receiving plate is located in the avoidance groove, inclined chutes are opened on both sides in the avoidance groove, a pin shaft is fixedly connected to one end of the receiving plate, and both ends of the pin shaft are respectively located in the two groups of inclined chutes. A rubber scraping plate is fixedly installed in the fuel tank, the end of the rubber scraping plate is attached to the outer ring of the disk body, a guiding ring is also fixedly installed in the fuel tank, the end of the receiving rod is closely attached to the inner ring of the guiding ring, and the inner ring of the guiding ring includes a first arc surface, an inclined surface, and a second arc surface;

[0011] Two sets of L-shaped clamping plates moving towards each other squeeze the sponge, so that most of the lubricating oil in the sponge is squeezed out. Part of the squeezed lubricating oil directly falls into the fuel tank, and the other part splashes onto the outer ring of the disc body or the rubber scraper. Until the end of the receiving rod slides onto the second arc surface, during the process of the end of the receiving rod sliding along the second arc surface, the two sets of L-shaped clamping plates keep squeezing the sponge. At the same time, the rubber scraper scrapes off the lubricating oil splashed onto the outer ring of the disc body, thus preventing the lubricating oil on the sponge from being splashed to the outside.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. By driving the guiding disc to rotate, the wire wheels in the six mounting grooves on the guiding disc can sequentially contact the lubricating oil in the fuel tank. The wire wheels attached with lubricating oil apply lubricating oil to the protective wire, realizing the lubrication of the protective wire, reducing the friction between the wire wheels, the perforations and the protective wire, thereby greatly reducing the wear of the protective wire and improving the quality of cable manufacturing.

[0014] 2. The rotating stranding disc drives the fourth gear to rotate, and the fourth gear drives the third gear, together with the transmission shaft and the oiling disc, to rotate. At the same time, the three sponges rotate together with the oiling disc, so that the three sponges sequentially and cyclically contact the lubricating oil in the fuel tank, enabling the sponges to absorb a certain amount of lubricating oil. When the sponge after absorbing the lubricating oil rotates to the uppermost end of the oiling disc, it will be squeezed by a row of wire wheels at the lowermost end of the guiding disc. The lubricating oil squeezed out from the sponge will adhere to the wire wheels, thereby realizing the above-mentioned application of lubricating oil to the protective wire by the wire wheels. Since the squeezing force of the wire wheels on the sponge is limited, the lubricating oil squeezed out from the sponge is relatively small, and a small amount of lubricating oil adheres to the wire wheels 602, thus avoiding excessive application of lubricating oil on the protective wire.

[0015] 3. When the sponge is separated from the contact with the lubricating oil, the end of the receiving rod slides to the inclined surface, and the receiving rod is squeezed by the inclined surface, causing the receiving rod to move towards the center of the disc body. At the same time, the receiving rod drives the movable rod and the supporting plate to move together, and the movable rod stretches the spring, and the supporting plate pulls the sponge towards the movable groove. The moving supporting plate drives the two receiving plates to slide along the two clearance grooves respectively. At the same time, the receiving plate drives the end of the pin shaft to slide along the inclined chute inside the clearance groove, so that the two sets of L-shaped clamping plates move towards each other along the slide rail. The two sets of L-shaped clamping plates moving towards each other squeeze the sponge, so that most of the lubricating oil in the sponge is squeezed out. Part of the squeezed lubricating oil directly falls into the fuel tank, and the other part splashes onto the outer ring of the disc body or the rubber scraper. Until the end of the receiving rod slides onto the second arc surface, during the process of the end of the receiving rod sliding along the second arc surface, the two sets of L-shaped clamping plates keep squeezing the sponge. At the same time, the rubber scraper scrapes off the lubricating oil splashed onto the outer ring of the disc body, thus preventing the lubricating oil on the sponge from being splashed to the outside.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0026] like Figures 1 to 3As shown in the figure, a cable stranding machine according to an embodiment of the present invention includes a wire placement rack 1, on which a wire installation roller 2 is rotatably installed. One end of the wire placement rack 1 is rotatably connected to a wire tube 3. A first gear 4, a protective wire placement disc 5, a guiding disc 6, and a stranding disc 7 are sequentially and fixedly sleeved on the wire tube 3. A die head 8 is placed directly in front of the wire tube 3. The first gear 4 meshes with a second gear 9, and the end of the second gear 9 is rotatably connected to the wire placement rack 1. Six groups of protective wire installation rollers 10 are rotatably installed at equal angles on the protective wire placement disc 5. An oil tank 11 is arranged directly below the guiding disc 6. Six groups of installation slots 601 are opened at equal angles on the guiding disc 6, and four wire wheels 602 are rotatably installed in the installation slots 601. Six groups of through holes 71 are opened at equal angles on the stranding disc 7.

[0027] Specifically, the four wire wheels 602 installed in the installation slots 601 are divided into two rows. The protective wire pulled out from the protective wire installation rollers 10 passes through between the two rows of wire wheels 602. The wire wheels 602 are in rolling connection with the protective wire. The oil tank 11 contains liquid lubricating oil. The liquid level of the lubricating oil is higher than the row of wire wheels 602 at the lowest end of the guiding disc 6 and lower than the outer ring of the guiding disc 6. Figure 3The dotted line in the middle indicates the lubricating oil level. When cable stranding is required, the wires pulled out from the wire installation roller 2 sequentially pass through the wire pipe 3 and the die head 8, and then the protective wires pulled out from the protective wire installation roller 10 pass through the two rows of wire wheels 602 on the guiding disc 6. Then, the protective wires sequentially pass through a set of perforations 71 on the stranding disc 7 and the die head 8. The remaining five sets of protective wire installation rollers 10 are pulled in the same way. Then, the six sets of protective wires and a set of wires are bundled together, and their ends are fixed to the winding device at the rear end. Then, the motor drives the second gear 9 to rotate, the second gear 9 drives the first gear 4 to rotate, and the first gear 4 drives the wire pipe 3 together with the protective wire placement disc 5, the guiding disc 6, and the stranding disc 7 to rotate, so that the six sets of protective wires and a set of wires are stranded into a cable in the die head 8. At the same time, the winding device at the rear end winds the stranded cable, so that the protective wires on the protective wire installation roller 10 and the wires on the wire installation roller 2 are continuously pulled out, realizing the manufacture of the cable. During this process, the wire wheels 602 will rotate with the guiding disc 6. During the rotation, the wire wheels 602 in the installation grooves 601 will rotate into the oil tank 11, and the row of guiding discs 6 close to the oil tank 11 direction will contact the lubricating oil, and this row of guiding discs 6 is not completely immersed in the lubricating oil. The lubricating oil will adhere to the guiding disc 6. At this time, the dragged protective wire drives the guiding disc 6 to rotate, so that the lubricating oil adhering to the guiding disc 6 rotates with the guiding disc 6, making the lubricating oil contact the protective wire, and the protective wire will adhere to the lubricating oil, realizing the lubricating oil being applied to the protective wire. Compared with the prior art, by driving the guiding disc 6 to rotate, the wire wheels 602 in the six sets of installation grooves 601 on the guiding disc 6 can sequentially contact the lubricating oil in the oil tank 11, and the protective wire is lubricated by the wire wheels 602 attached with the lubricating oil, realizing the lubrication of the protective wire, reducing the friction between the wire wheels 602, the perforations 71 and the protective wire, thereby greatly reducing the wear of the protective wire and improving the quality of cable manufacture.

[0028] As Figure 4 shown, an oiling mechanism 12 is arranged in the oil tank 11. The oiling mechanism 12 includes a transmission shaft 121, the transmission shaft 121 is rotationally connected to the oil tank 11, a third gear 122 is fixedly sleeved at one end of the transmission shaft 121, a fourth gear 123 meshing with the third gear 122, an oiling disc 124, the oiling disc 124 is fixedly installed at the other end of the transmission shaft 121, six sets of sponges 125 are equiangularly installed on the outer ring of the oiling disc 124, the fourth gear 123 is fixedly sleeved on the stranding disc 7, the oiling disc 124 is located in the oil tank 11, and the oiling disc 124 is located directly below the guiding disc 6.

[0029] Specifically, the lubricating oil in the fuel tank 11 is taken out through the wire wheel 602 and applied to the protective wire. However, the protective wire will move above the lubricating oil level together with the wire wheel 602. At this time, the dragged protective wire will drive the wire wheel 602 to rotate rapidly. Since the wire wheel 602 is immersed in the lubricating oil, a large amount of lubricating oil will be applied to the protective wire by the wire wheel 602 at this time, resulting in an excessive amount of lubricating oil on the protective wire. The excessive lubricating oil will drip along the transmission path of the protective wire, not only causing waste of lubricating oil, but also polluting the surrounding environment with lubricating oil. In the initial state, the lubricating oil level in the fuel tank 11 is lower than the outer ring of the oiling disc 124 and higher than the sponge 125 at the lowest end of the oiling disc 124. Therefore, when applying lubricating oil to the protective wire, the rotating stranding disc 7 drives the fourth gear 123 to rotate, and the fourth gear 123 drives the third gear 122 together with the transmission shaft 121 and the oiling disc 124 to rotate. At the same time, the three groups of sponges 125 rotate together with the oiling disc 124, so that the three groups of sponges 125 sequentially and cyclically contact the lubricating oil in the fuel tank 11, enabling the sponges 125 to absorb a certain amount of lubricating oil. When the sponge 125 after absorbing the lubricating oil rotates to the uppermost end of the oiling disc 124, it will be squeezed by a row of wire wheels 602 at the lowermost end of the guiding disc 6. The lubricating oil squeezed out from the sponge 125 will adhere to the wire wheels 602, thus realizing the application of lubricating oil to the protective wire by the wire wheels 602. Since the extrusion force of the wire wheels 602 on the sponge 125 is limited, less lubricating oil is squeezed out from the sponge 125, and a small amount of lubricating oil adheres to the wire wheels 602, thereby avoiding excessive application of lubricating oil to the protective wire. Embodiment 2

[0030] As Figures 5 to 7As shown in the figure, compared with the first comparative example, another implementation mode of the present invention is as follows: The oiling plate 124 includes a plate body 1241. The plate body 1241 is fixedly sleeved on the other end of the transmission shaft 121. Six groups of movable grooves 1242 are arranged at equal angles on the outer ring of the plate body 1241. Two groups of L-shaped clamping plates 1243 are symmetrically arranged in the movable grooves 1242. A support plate 1244 is arranged between the two groups of L-shaped clamping plates 1243. A sponge 125 is fixedly installed on the support plate 1244. A movable rod 1245 fixedly connected to the support plate 1244. A spring 1246 is sleeved on the movable rod 1245. A connecting rod 1247 fixedly connected to the end of the movable rod 1245. A slide rail 1248 is arranged in the movable groove 1242. A guide groove 33 is opened at the bottom of the L-shaped clamping plate 1243. The guide groove 33 is slidably connected to the slide rail 1248. The connecting rod 1247 passes through the slide rail 1248 and extends into the inner cavity of the plate body 1241. One end of the spring 1246 is fixedly connected to the end of the movable rod 1245, and the other end of the spring 1246 is fixedly connected to the inner wall of the plate body 1241. An avoidance groove 31 is opened on the L-shaped clamping plate 1243. A receiving plate 41 is arranged on both sides of the support plate 1244. One end of the receiving plate 41 is located in the avoidance groove 31. Oblique chutes 32 are opened on both sides in the avoidance groove 31. A pin shaft 42 is fixedly connected to one end of the receiving plate 41. Both ends of the pin shaft 42 are respectively located in the two groups of oblique chutes 32. A rubber scraping plate 111 is fixedly installed in the fuel tank 11. The end of the rubber scraping plate 111 is attached to the outer ring of the plate body 1241. A guiding ring 112 is also fixedly installed in the fuel tank 11. The end of the connecting rod 1247 is closely attached to the inner ring of the guiding ring 112. The inner ring of the guiding ring 112 includes a first arc surface 21, an oblique surface 22, and a second arc surface 23.

[0031] Specifically, the sponge 125 after absorbing lubricating oil will generate centrifugal force as the oiling plate 124 rotates. The centrifugal force will cause a part of the lubricating oil in the sponge 125 to be thrown out. The thrown lubricating oil will splash onto the rotating wire wheel 602. The rotating wire wheel 602 will throw the lubricating oil to the outside, resulting in waste of lubricating oil and pollution of the surrounding environment. Therefore, after the sponge 125 is immersed in oil, during the process of the oiling plate 124 driving the oil-soaked sponge 125 to rotate, Figure 5The direction indicated by the middle arrow is the direction of rotation. The end of the receiving rod 1247 will first slide along the first arc surface 21 in the inner ring of the guide ring 112. When the sponge 125 is out of contact with the lubricating oil, the end of the receiving rod 1247 slides to the inclined surface 22, and the receiving rod 1247 is squeezed by the inclined surface 22, so that the receiving rod 1247 moves toward the center of the disk body 1241. At the same time, the receiving rod 1247 drives the movable rod 1245 to move together with the support plate 1244, and the movable rod 1245 moves. 245 stretches the spring 1246, and the support plate 1244 pulls the sponge 125 to move into the movable groove 1242. The moving support plate 1244 drives the two groups of receiving plates 41 to slide along the two groups of avoiding grooves 31 respectively. At the same time, the receiving plate 41 drives the end of the pin shaft 42 to slide along the oblique slide groove 32 inside the avoiding groove 31, so that the two groups of L-shaped clamping plates 1243 move toward each other along the slide rail 1248. The two groups of L-shaped clamping plates 1243 moving toward each other squeeze the sponge 125, so that the sponge 125 Most of the lubricating oil is squeezed out, and part of the squeezed lubricating oil falls directly into the oil tank 11, and the other part splashes onto the outer ring of the disk body 1241 or the rubber scraper 111 until the end of the receiving rod 1247 slides onto the second curved surface 23. During the sliding process of the end of the receiving rod 1247 along the second curved surface 23, the two sets of L-shaped clamping plates 1243 keep squeezing the sponge 125, and at the same time, the rubber scraper 111 scrapes off the lubricating oil splashed onto the outer ring of the disk body 1241 , thereby preventing the lubricating oil on the sponge 125 from being thrown to the outside, until the end of the receiving rod 1247 is offset from the second curved surface 23, and under the action of the rebound force of the spring 1246, the squeezing of the sponge 125 by the two sets of L-shaped clamping plates 1243 is released, and at the same time, the sponge 125 is separated from the movable groove 1242, and the end of the receiving rod 1247 slides along the first curved surface 21. During the sliding process, the sponge 125 is squeezed against the wire wheel 602, so that the sponge 125 can apply lubricating oil to the wire wheel 602.

[0032] Working principle: The wire pulled out from the wire installation roller 2 passes through the wire tube 3 and the die head 8 in sequence, and then the protective wire pulled out from the protective wire installation roller 10 passes through two rows of wire wheels 602 on the guiding disk 6. Then the protective wire passes through a set of perforations 71 on the stranding disk 7 and the die head 8 in sequence. The remaining five sets of protective wire installation rollers 10 are pulled in the same way. Then the six sets of protective wires and one set of wires are bundled together, and their ends are fixed on the winding device at the rear end. Then the motor drives the second gear 9 to rotate, the second gear 9 drives the first gear 4 to rotate, and the first gear 4 drives the wire tube 3 together with the protective wire placement disk 5, the guiding disk 6, and the stranding disk 7 to rotate, so that the six sets of protective wires and one set of wires are stranded into a cable in the die head 8. At the same time, the winding device at the rear end winds the stranded cable, so that the protective wires on the protective wire installation roller 10 and the wires on the wire installation roller 2 are continuously pulled out, realizing the manufacture of the cable. During this process, the wire wheel 602 will rotate with the guiding disk 6. During the rotation, the wire wheel 602 in the installation groove 601 will rotate into the oil tank 11, and one row of guiding disks 6 close to the oil tank 11 direction will contact the lubricating oil, and this row of guiding disks 6 is not completely immersed in the lubricating oil. The lubricating oil will adhere to the guiding disk 6. At this time, the dragged protective wire drives the guiding disk 6 to rotate, so that the lubricating oil adhering to the guiding disk 6 rotates with the guiding disk 6, bringing the lubricating oil into contact with the protective wire, and the protective wire will adhere to the lubricating oil, realizing the application of the lubricating oil to the protective wire;

[0033] When applying lubricating oil to the protective wire, the rotating stranding disk 7 drives the fourth gear 123 to rotate, and the fourth gear 123 drives the third gear 122 together with the transmission shaft 121 and the oiling disk 124 to rotate. At the same time, the three sets of sponges 125 rotate with the oiling disk 124, so that the three sets of sponges 125 sequentially and cyclically contact the lubricating oil in the oil tank 11, enabling the sponges 125 to absorb a certain amount of lubricating oil. When the sponge 125 after absorbing the lubricating oil rotates to the uppermost end of the oiling disk 124, it will be squeezed by the lowest row of wire wheels 602 on the guiding disk 6, and the lubricating oil extruded from the sponge 125 will adhere to the wire wheel 602, thus realizing the application of the lubricating oil to the protective wire by the above-mentioned wire wheel 602;

[0034] After the sponge 125 is immersed in oil, during the rotation of the oiling disk 124 driving the oil-soaked sponge 125, the following attachment Figure 5The direction indicated by the arrow in the figure is the rotation direction. The end of the receiving rod 1247 will first slide along the first arc surface 21 in the inner ring of the guiding ring 112. When the sponge 125 is separated from the lubricating oil, the end of the receiving rod 1247 slides to the inclined surface 22, and the receiving rod 1247 is squeezed by the inclined surface 22, causing the receiving rod 1247 to move towards the center of the disc body 1241. At the same time, the receiving rod 1247 drives the movable rod 1245 and the support plate 1244 to move together, and the movable rod 1245 stretches the spring 1246, and the support plate 1244 pulls the sponge 125 to move into the movable groove 1242. The moving support plate 1244 drives the two receiving plates 41 to slide along the two clearance grooves 31 respectively. At the same time, the receiving plate 41 drives the end of the pin shaft 42 to slide along the inclined sliding groove 32 inside the clearance groove 31, so that the two L-shaped clamping plates 1243 move towards each other along the slide rail 1248. The two L-shaped clamping plates 1243 moving towards each other squeeze the sponge 125, so that most of the lubricating oil in the sponge 125 is squeezed out. And a part of the squeezed lubricating oil directly falls into the fuel tank 11, and the other part will splash onto the outer ring of the disc body 1241 or the rubber squeegee 111. Until the end of the receiving rod 1247 slides onto the second arc surface 23. During the process of the end of the receiving rod 1247 sliding along the second arc surface 23, the two L-shaped clamping plates 1243 keep squeezing the sponge 125. At the same time, the rubber squeegee 111 scrapes off the lubricating oil splashed onto the outer ring of the disc body 1241.
