Specific embodiments

[0029] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments.

[0030] Embodiment 1

[0031] Referring to Figures 1-4 , a cable cutting device includes a workbench 1. Both outer walls of the two sides of the top of the workbench 1 are fixedly connected with support platforms 2, and a fixed cylinder 3 is symmetrically and fixedly connected between the two support platforms 2. Fixed mechanisms are arranged on the outer walls of the two fixed cylinders 3, and an elliptical pressing cloth 21 is symmetrically arranged between the two fixed cylinders 3. A cutting mechanism is arranged directly above the middle of the two elliptical pressing cloths 21. Rotating columns 22 are fixedly connected to both ends of each elliptical pressing cloth 21. A moving plate 20 is arranged at one end of each rotating column 22, and the rotating column 22 is rotatably connected to the outer wall of the moving plate 20. Threaded sliders 16 are fixedly connected to the bottom outer walls of the moving plates 20, and an adjustment mechanism is arranged in the middle of the threaded sliders 16 at the same end. A driving mechanism for driving the rotating column 22 to rotate is arranged on the top of the workbench 1. When cutting the cable, rotating the rotating columns 22 at both ends of the elliptical pressing cloth 21 can make the elliptical pressing cloth 21 closely adhere to the surface of the cable, realizing the rapid bundling and pressing of the cable, and avoiding subsequent loosening, thereby avoiding the situation of the cable becoming loose strands when cutting the cable and improving the efficiency of cutting the cable.

[0032] As a further solution in the present invention, the fixing mechanism includes two fixing plates 8, which are symmetrically and fixedly connected to the outer wall of one side of the fixing cylinder 3. Electric push rods II 9 are fixedly connected to the middle parts of the two fixing plates 8. One ends of the two electric push rods II 9 are fixedly connected to the same moving cylinder 7, and the moving cylinder 7 is sleeved on the outer wall of the fixing cylinder 3. A plurality of pressing rods 10 are equidistantly arranged between the moving cylinder 7 and the fixing cylinder 3, and one ends of the pressing rods 10 are hinged to the outer wall of the fixing cylinder 3. The cable to be cut is passed through the fixing cylinder 3, and then the two ends of the cable are placed on the support table. Then, the electric push rods II 9 in the fixing mechanism are started, so as to push the moving cylinder 7 sleeved on the fixing cylinder 3 to move. During this process, the inner wall of the moving cylinder 7 will contact the plurality of pressing rods 10.

[0033] As a further solution in the present invention, a plurality of sliding rods 14 are equidistantly and slidably connected to the outer wall of one side of the fixing cylinder 3. Fixed arc-shaped plates 15 are fixedly connected to the outer walls of the bottoms of the plurality of sliding rods 14. Pressing plates 11 are fixedly connected to the outer walls of the tops of the sliding rods 14, and positioning grooves 13 are formed in the outer walls of the tops of the pressing plates 11. One ends of the connecting springs I 12 are fixedly connected between the bottoms of the pressing plates 11 and the fixing cylinder 3. The other ends of the pressing rods 10 are located in the positioning grooves 13 at the tops of the corresponding pressing plates 11, so that the upwardly warped ends of the pressing rods 10 can move downward, and then the sliding rods 14 can be pushed downward through the pressing plates 11, enabling the fixed arc-shaped plates 15 at the lower ends of the plurality of sliding rods 14 to move towards the surface of the cable until the cable is clamped and fixed, so as to fix cables with different diameters and make them in a straightened state, which is convenient for cutting them.

[0034] As a further solution in the present invention, the adjusting mechanism includes a bidirectional threaded rod 17, which is arranged on the outer wall of the top of the workbench 1. The first threaded slider 16 is threadedly and slidably connected to the outer wall of the bidirectional threaded rod 17, and the bottom of the first threaded slider 16 is slidably connected to the workbench 1. A first rotating motor 18 is arranged on one side of the bidirectional threaded rod 17. By the first rotating motor 18, the bidirectional threaded rod 17 can be rotated, and the distance between the two first threaded sliders 16 on its outer wall can be adjusted, so as to adjust the distance between the two elliptical pressing cloths 21 through the moving plate 20, and avoid damage to the elliptical pressing cloth 21 when the cutting mechanism cuts the cable.

[0035] As a further solution in the present invention, the driving mechanism includes a rotating shaft 26, which is rotatably connected between the moving plates 20 at both ends of each elliptical pressing cloth 21. Both outer walls of the rotating shaft 26 are fixedly connected with second pulleys 25, and a belt 24 is sleeved on the outer wall of the second pulleys 25. A first pulley 23 is arranged at the top of the belt 24, and the first pulley 23 is fixedly connected to the outer wall of the rotating column 22. A second rotating motor 19 is arranged at one end of the rotating shaft 26. Starting the second rotating motor 19 can rotate the rotating shaft 26. The rotating shaft 26 can synchronously drive the two second pulleys 25 on its outer wall to rotate. Through the transmission of the belt 23, the rotating column 22 with the first pulley 23 can be rotated.

[0036] As a further solution in the present invention, the cutting mechanism includes a first mounting frame 4, which is welded to the outer wall of the workbench 1. An electric push rod 5 is arranged in the middle of the workbench 1, and a cutting machine 6 is arranged at the bottom end of the electric push rod 5. The electric push rod 5 moves the cutting machine 6 downward, so as to cut the cable.

[0037] Working principle: Pass the cable to be cut through the fixed cylinder 3, then let both ends of the cable rest on the support table. Then start the electric push rod 9 in the fixing mechanism, so as to push the moving cylinder 7 sleeved on the fixed cylinder 3 to move. During this process, the inner wall of the moving cylinder 7 will contact with multiple pressing rods 10. Since one ends of the pressing rods 10 are all located in the positioning grooves 13 on the tops of the corresponding pressing plates 11, the upwardly warped ends of the pressing rods 10 can be moved downward, so that the sliding rods 14 can be moved downward through the pressing plates 11, and the fixed arc-shaped plates 15 at the lower ends of the multiple sliding rods 14 can be moved towards the cable surface until the cable is clamped and fixed, so as to fix cables with different diameters and make them in a straightened state, which is convenient for cutting. Then, the first rotating motor 18 can rotate the bidirectional threaded rod 17, and the distance between the two first threaded sliders 16 on its outer wall can be adjusted, so as to adjust the distance between the two elliptical pressing cloths 21 through the moving plates 20, avoiding damage to the elliptical pressing cloth 21 when the cutting mechanism cuts the cable. Then start the second rotating motor 19, so that the rotating shaft 26 can rotate. The rotating shaft 26 can synchronously drive the two second pulleys 25 on its outer wall to rotate. Through the transmission of the belt 23, the rotating column 22 with the first pulley 23 can be rotated, so that the elliptical pressing cloth 21 is closely attached to the cable surface, realizing rapid bundling and pressing of the cable and avoiding subsequent loosening. Finally, the electric push rod 5 moves the cutting machine 6 downward to cut the cable, thus avoiding the situation of the cable becoming loose when cutting the cable and improving the cutting efficiency of the cable.

[0038] Embodiment 2

[0039] Refer to Figures 1-6, A cable cutting device. Compared with Embodiment 1, on the basis of Embodiment 1, at the top outer wall of the moving plates 20 at both ends of each elliptical pressing cloth 21, the same second mounting frame 27 is welded, and a threaded rod 29 is rotatably connected to the inner wall of the second mounting frame 27. One end of the threaded rod 29 is provided with a third rotating motor 28, and a second threaded slider 30 is threadedly slidably connected to the outer wall of the threaded rod 29. When the rotating columns 22 at both ends of the elliptical pressing cloth 21 rotate, the third rotating motor 28 on the second mounting frame 27 is synchronously started. The third rotating motor 28 drives the threaded rod 29 to rotate, causing the second threaded slider 30 on its outer wall to reciprocate.

[0040] As a further scheme in the present invention, a mounting cylinder 31 is fixedly connected to the bottom outer wall of the second threaded slider 30, and a telescopic rod 34 is slidably connected to the bottom of the mounting cylinder 31. A second connecting spring 35 is fixedly connected between the top of the telescopic rod 34 and the inner wall of the mounting cylinder 31, and a third mounting frame 32 is fixedly connected to the bottom outer wall of the telescopic rod 34. A smoothing roller 33 is rotatably connected to the inner wall of the third mounting frame 32. Thus, the mounting cylinder 31 is synchronously driven to move. Under the elastic force of the second connecting spring 35 inside the mounting cylinder 31, the smoothing roller 33 in the third mounting frame 35 at the lower end of the telescopic rod 34 is in close contact with the upper surface of the elliptical pressing cloth 21, thereby avoiding the occurrence of wrinkles when the elliptical pressing cloth 21 rotates at both ends, ensuring the contact area between the elliptical pressing cloth 21 and the cable, and increasing the bundling and pressing effect.

[0041] Working principle: When the rotating columns 22 at both ends of the elliptical pressing cloth 21 rotate, the third rotating motor 28 on the second mounting frame 27 is synchronously started. The third rotating motor 28 drives the threaded rod 29 to rotate, causing the second threaded slider 30 on its outer wall to reciprocate, thereby synchronously driving the mounting cylinder 31 to move. Under the elastic force of the second connecting spring 35 inside the mounting cylinder 31, the smoothing roller 33 in the third mounting frame 35 at the lower end of the telescopic rod 34 is in close contact with the upper surface of the elliptical pressing cloth 21, thereby avoiding the occurrence of wrinkles when the elliptical pressing cloth 21 rotates at both ends, ensuring the contact area between the elliptical pressing cloth 21 and the cable, and increasing the bundling and pressing effect.

[0042] Embodiment 3

[0043] Refer to Figures 1-7 , A cable cutting device. Compared with Embodiment 2, on the basis of Embodiment 2, isolation covers 36 are provided on the outside of both the bidirectional threaded rods 17, and the isolation covers 36 are fixedly connected to the top outer wall of the workbench 1. The outer wall of the first threaded slider 16 is in close contact with the inner wall of the isolation cover 36. Through grooves 38 are opened on the opposite sides of the two first threaded sliders 16, and a through groove 38 is also opened on the side of one of the first threaded sliders 16 close to the other first threaded slider 16.

[0044] As a further solution in the present invention, a pair of mounting plates 40 are fixedly connected to the inner walls of the bottom of the through groove 38, and a winding column 39 is rotatably connected between each pair of mounting plates 40 through a torsion spring. A shielding cloth 37 is wound around the outer wall of the winding column 39. One end of the shielding cloth 37 on both sides is fixedly connected to the inner wall of the isolation cover 36, and one end of the shielding cloth 37 in the middle is fixedly connected to the outer wall of one side of the threaded slider 16. When the threaded slider 16 moves, the shielding cloth 37 on the surface of the winding column 39 in the through groove 38 can be loosened or wound. With the cooperation of the three shielding cloths 37 and the isolation cover 36, the bidirectional threaded rod 17 can be protected to prevent debris generated during cable cutting from falling into the thread gap of the bidirectional threaded rod 17 and causing jamming, ensuring operation. Moreover, the waste chips generated during cutting will fall on the shielding cloth 37, which is convenient for the staff to clean up the waste chips after cutting.

[0045] Working principle: When the threaded slider 16 moves under the action of the adjustment mechanism, the shielding cloth 37 on the surface of the winding column 39 in the through groove 38 can be loosened or wound. With the cooperation of the three shielding cloths 37 and the isolation cover 36, the bidirectional threaded rod 17 can be protected to prevent debris generated during cable cutting from falling into the thread gap of the bidirectional threaded rod 17 and causing jamming, ensuring operation. Moreover, the waste chips generated during cutting will fall on the shielding cloth 37, which is convenient for the staff to clean up the waste chips after cutting.
