Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a stranding machine for cable production. Background Technology

[0002] In the cable production process, the stranding process involves twisting multiple single wires together according to a specified twist pitch and direction to form a cable core, while the winding process involves neatly winding the stranded cable. Both processes play a crucial role in the quality and production efficiency of the cable.

[0003] Existing technical problems: Unstable stranding quality: Traditional stranding machines have poor cable mounting component fixation. During high-speed rotation, the cable drum is prone to shaking or displacement, resulting in uneven stress on multiple cables. The stranded cables are of varying thickness, and the stranding pitch does not meet the production requirements of high-standard cables. Furthermore, common winding devices lack effective cable guidance and compaction structures, and the cables are prone to tangling and inconsistent tightness during winding, which seriously affects the appearance quality and subsequent use of the cables. Therefore, it is necessary to design a stranding machine for cable production to solve the above problems. Summary of the Invention

[0004] The main objective of this invention is to provide a stranding machine for cable production, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A stranding machine for cable production includes a base, a support plate fixedly connected to the upper left part of the base, a stranding device fixedly connected to the upper left part of the support plate, and a winding device fixedly connected to the upper rear part of the base.

[0007] The stranding device includes a first drive motor, the output end of which passes through a support plate and is fixedly connected to a connecting plate. A rotating column is fixedly connected to the right end of the connecting plate. A cable mounting assembly is fixedly connected to the middle of the outer surface of the rotating column. A stranding reel is fixedly connected to the right end of the rotating column. A stranding frame is fixedly connected to the upper and lower right ends of the stranding reel. A stranding groove is opened in the middle of the right end of the stranding frame. Three grooves are opened in the right end of the stranding reel. The first drive motor is fixedly connected to the upper left end of the support plate.

[0008] Preferably, the cable mounting assembly includes a fixed triangular block, with a connecting shaft block fixedly connected to the outer side of each of the three fixed triangular blocks. A sleeve rod is fixedly connected to the other end of each of the three connecting shaft blocks. A mounting screw hole is opened at the other end of each sleeve rod, and a fixing bolt is threaded into each mounting screw hole. A cable cylinder is sleeved on the outer surface of the sleeve rod, and the fixed triangular block is fixedly connected to the middle of the outer surface of the rotating column.

[0009] Preferably, the winding device includes a side plate and a second drive motor. Two first connecting shafts are fixedly connected to the left front end of the side plate, and the two first connecting shafts are symmetrically distributed vertically. An upper rotating wheel and a lower rotating wheel are fixedly connected to the outer surface of the first connecting shafts, and four cable winding grooves are opened on the outer surface of the upper rotating wheel and the lower rotating wheel. A second connecting shaft is fixedly connected to the middle front end of the side plate, and a cable pressing wheel is fixedly connected to the front end of the second connecting shaft. The output end of the second drive motor passes through the side plate and is fixedly connected to a limiting plate. A winding rod is fixedly connected to the middle front end of the limiting plate. The side plate is fixedly connected to the upper rear end of the base.

[0010] Preferably, the stranded wire reel has a disc-shaped structure, and the three grooves are arranged in a circular array with the center of the stranded wire reel as the center, and the depth direction of the grooves is perpendicular to the surface of the stranded wire reel.

[0011] Preferably, the upper rotating wheel is disc-shaped, and the four cable winding grooves are distributed in a ring array on the outer circumference of the upper rotating wheel, and the cross-section of the cable winding grooves is arc-shaped.

[0012] Preferably, the stranding frame is a U-shaped frame structure with its opening facing the center of the stranding reel, and the cross-section of the stranding groove is a circular groove.

[0013] Preferably, the three outer planes of the fixed triangular block are perpendicularly connected to the fixed ends of the three connecting shaft blocks, and the threaded end of the fixing bolt passes through the mounting screw hole and abuts against the end face of the cable cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the cable installation assembly of this stranding machine, the three outer planes of the fixed triangular block are perpendicularly connected to the connecting shaft block, and the included angle between adjacent connecting shaft blocks is 120°, so that the three sleeve rods are distributed in an equilateral triangle. The cable drum is fixed to the sleeve rod by the fixing bolt, ensuring that the cable drum is stable and does not loosen when rotating at high speed. At the same time, the grooves on the stranding disc are distributed in a ring array, which can ensure that the cable is evenly stressed. Combined with the U-shaped stranding frame and the circular stranding groove, the cable stranding is tighter and more regular in shape, effectively solving the problems of uneven cable thickness and substandard stranding pitch after stranding, significantly improving the stranding quality and meeting the production requirements of high-standard cables.

[0016] 2. In the winding device of this stranding machine, the outer surfaces of the upper and lower rotating wheels, which are symmetrically distributed, are provided with annular arrays of arc-shaped cable winding grooves. When the cable passes through, it can be evenly stressed and initially shaped. The horizontally arranged pressing wheel can further compact the cable structure. The symmetrical first connecting shaft ensures smooth cable delivery and reduces cable wear. Under the synergistic action of the pressing wheel and the winding rod, the cable is wound tightly and orderly, effectively avoiding the phenomenon of cable tangling and inconsistent tightness, which greatly improves the appearance quality and subsequent performance of the cable.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A stranding machine for cable production includes a base 1, a support plate 2 fixedly connected to the upper left part of the base 1, a stranding device 3 fixedly connected to the upper left part of the support plate 2, and a winding device 4 fixedly connected to the upper rear part of the base 1.

[0027] In this embodiment, the stranding device 3 includes a first drive motor 31. The output end of the first drive motor 31 passes through the support plate 2 and is fixedly connected to a connecting plate 32. A rotating column 33 is fixedly connected to the right end of the connecting plate 32. A cable mounting assembly 34 is fixedly connected to the middle of the outer surface of the rotating column 33. A stranding disc 35 is fixedly connected to the right end of the rotating column 33. A stranding frame 37 is fixedly connected to the upper and lower parts of the right end of the stranding disc 35. A stranding groove 38 is opened in the middle of the right end of the stranding frame 37. Three grooves 36 are opened in the right end of the stranding disc 35. The first drive motor 31 is fixedly connected to the upper left end of the support plate 2. The cable mounting assembly 34 includes a fixing triangular block 341. A connecting shaft block 342 is fixedly connected to the outer side of each fixing triangular block 341. The other end of each of the three connecting shaft blocks 342 is fixedly connected to a cable mounting assembly 35. The sleeve rod 343 has mounting screw holes 344 at one end, and fixing bolts 345 are threaded into the mounting screw holes 344. A cable drum 346 is fitted onto the outer surface of the sleeve rod 343. A fixing triangular block 341 is fixedly connected to the middle of the outer surface of the rotating column 33. The stranded wire reel 35 has a disc-shaped structure. Three grooves 36 are arranged in a circular array with the center of the stranded wire reel 35 as the center, and the depth direction of the grooves 36 is perpendicular to the surface of the stranded wire reel 35. The stranded wire frame 37 has a U-shaped frame structure with its opening facing the center of the stranded wire reel 35. The cross-section of the stranded wire groove 38 is a circular groove 36. The three outer planes of the fixing triangular block 341 are perpendicularly connected to the fixing ends of the three connecting shaft blocks 342. The threaded end of the fixing bolt 345 passes through the mounting screw hole 344 and abuts against the end face of the cable drum 346.

[0028] With the above solution: when the first drive motor 31 starts, its output end drives the connecting plate 32 to rotate, which in turn causes the rotating column 33 to rotate. The cable mounting assembly 34 fixed in the middle of the rotating column 33 rotates synchronously. Since the three outer planes of the fixed triangular block 341 are perpendicularly connected to the connecting shaft block 342, and the included angle between adjacent connecting shaft blocks 342 is 120°, the three sleeve rods 343 are distributed in an equilateral triangle. The cable tube 346 sleeved on the sleeve rod 343 is tightly fixed by the fixing bolt 345, ensuring that the cable tube 346 rotates smoothly. The cable, after being drawn out from the cable drum 346, passes through the three grooves 36 arranged in a ring on the stranding reel 35 and enters the circular stranding groove 38 of the U-shaped stranding frame 37. Under the continuous rotation of the rotating column 33, multiple cables are evenly stranded. The beneficial effects of this structural design are: the ring array distribution of the grooves 36 ensures that the cable is subjected to uniform force, improving the stranding quality; the cooperation between the U-shaped stranding frame 37 and the circular stranding groove 38 makes the cable stranding tighter and more regular in shape, effectively improving the efficiency of cable production and the quality of finished products.

[0029] In this embodiment, the winding device 4 includes a side plate 41 and a second drive motor 42. Two first connecting shafts 45 are fixedly connected to the left front end of the side plate 41, and the two first connecting shafts 45 are symmetrically distributed vertically. An upper rotating wheel 46 and a lower rotating wheel 48 are fixedly connected to the outer surface of the first connecting shafts 45, respectively. Four cable winding grooves 47 are opened on the outer surface of both the upper rotating wheel 46 and the lower rotating wheel 48. A second connecting shaft 49 is fixedly connected to the middle front end of the side plate 41, and a cable pressing wheel 410 is fixedly connected to the front end of the second connecting shaft 49. The output end of the second drive motor 42 passes through the side plate 41 and is fixedly connected to a limiting disk 43. A winding rod 44 is fixedly connected to the middle front end of the limiting disk 43. The side plate 41 is fixedly connected to the upper rear end of the base 1. The upper rotating wheel 46 is disc-shaped, and the four cable winding grooves 47 are distributed in a circular array on the outer circumference of the upper rotating wheel 46, and the cross-section of the cable winding grooves 47 is arc-shaped.

[0030] Through the above scheme: when the second drive motor 42 starts, its output end drives the limit plate 43 and the winding rod 44 to rotate synchronously, providing power for cable winding. The twisted cable first passes through the upper rotating wheel 46 and the lower rotating wheel 48, which are symmetrically distributed. Since the four cable winding grooves 47 are distributed in a ring array on the outer surface of the rotating wheel and the cross section is arc-shaped, the cable can be evenly stressed and initially shaped when passing through. Then the cable passes through the pressure wheel 410 at the front end of the horizontally set second connecting shaft 49, which further compacts the cable structure. Finally, the cable is wound onto the winding rod 44. The upper and lower symmetrical first connecting shaft 45 ensures that the cable is transported smoothly. The arc-shaped cable winding grooves 47 reduce cable wear. The synergistic effect of the pressure wheel 410 and the winding rod 44 makes the cable winding tight and orderly, effectively improving the efficiency of cable production and the quality of finished products.

[0031] It should be noted that this utility model is a stranding machine for cable production. When the stranding machine is working, the first drive motor 31 starts, and its output end drives the connecting plate 32 to rotate, thereby rotating the rotating column 33. The cable mounting assembly 34, which is fixed in the middle of the outer surface of the rotating column 33, rotates accordingly. The cable drum 346 is sleeved on the sleeve rod 343 and is fixed by the fixing bolt 345 passing through the mounting screw hole 344. After the cable is led out from the cable drum 346, it passes through the groove 36 on the stranding disc 35 and enters the U-shaped frame structure of the stranding frame 37 and its... The cable twisting groove 38 in the central circular groove 36 achieves cable twisting during the rotation of the rotating column 33. The twisted cable passes through the arc-shaped cable winding grooves 47 distributed in a ring array on the outer surface of the upper rotating wheel 46 and the lower rotating wheel 48 in sequence, and is initially compacted by the pressing wheel 410. Finally, the second drive motor 42 starts, driving the limit plate 43 and the winding rod 44 to rotate, and winding the cable onto the winding rod 44. The support plate 2 and the side plate 41 on the base 1 provide stable support for the twisting device 3 and the winding device 4 respectively, ensuring that the entire twisting and winding process proceeds smoothly.
