Description

Technical Field

[0001] This utility model relates to the technical field of network cable processing devices, specifically to a network cable cutting machine. Background Technology

[0002] A network cable cutting machine is a specialized piece of equipment used for processing network cables. It mainly consists of a base, a positioning mechanism, a clamping mechanism, and a cutting mechanism. The base provides stable support for the entire machine, and the positioning mechanism on its upper surface limits the network cable position. The clamping mechanism can move on the base, moving closer to or further away from the positioning mechanism. It has an internal drive mechanism that moves the clamping blocks longitudinally to grip the network cable and adjusts the cutting length in conjunction with the positioning mechanism. The cutting mechanism can move horizontally, and its internal cutting blade, working in conjunction with related components, accurately cuts the network cable. All these mechanisms work together to achieve automatic positioning, clamping, and cutting of the network cable.

[0003] Chinese utility model patent (publication number CN221848517U) discloses a wire harness cutting device for wire harness processing, including a base plate, a support base fixedly connected to the bottom of the base plate, and a cutting mechanism and a clamping mechanism respectively arranged on the top of the base plate. The cutting mechanism is located on top of the clamping mechanism, and a clamping plate is arranged on top of the clamping mechanism. The cutting mechanism includes a top plate, which is fixedly connected to the top of the base plate. A sliding groove and a graduated groove are respectively opened in the top plate. The sliding groove is located on the side of the graduated groove, and a sliding plate is slidably connected in the sliding groove. An electric telescopic rod is installed at the bottom of the sliding plate, and a cutter is fixedly connected to the bottom of the electric telescopic rod. A rack is fixedly connected to the side of the sliding plate. By setting up the cutting mechanism, the wire harness body can be cut at different positions, improving the practicality of processing the wire harness body. At the same time, by observing the graduated groove, the cutter can move more accurately, thereby improving the accuracy of cutting the wire harness body, making the cutting device more practical in use.

[0004] The wire harness cutting device described above requires manual placement of the wire harness inside the fixing box, followed by turning a screw to push the pressing plate downwards, thereby fixing both ends of the wire harness. However, this frequent manual operation disrupts the continuity of the cutting process and significantly affects the overall efficiency of network cable cutting. Utility Model Content

The positioning mechanism is provided with lower limit rollers at equal intervals corresponding to the number of upper limit rollers.

After the wire mesh is cut, the drive mechanism controls the clamping blocks to move away from each other, allowing the cut wire mesh to fall naturally. The repeated movement of the second moving frame completes the automatic feeding of the wire mesh, avoiding the problem of repeatedly fixing the wire mesh after cutting. Attached Figure Description

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] See Figures 1-6 As shown, a network cable cutting machine includes a base 1. The upper end surface of the base 1 is provided with a positioning mechanism 2 for limiting the position. The top of the base 1 is provided with a clamping mechanism 4 that can move closer to or away from the positioning mechanism 2. The clamping mechanism 4 includes a second movable frame 41. On the side of the second movable frame 41 facing the positioning mechanism 2, there are two sets of clamping blocks 45 that can move closer to or away from each other for clamping the network cable. Inside the second movable frame 41, there is a drive mechanism 44 that can drive the two sets of clamping blocks 45 to move longitudinally. The drive mechanism 44 is hinged to the two sets of clamping blocks 45.

[0028] When the drive mechanism 44 is on one side of the positioning mechanism 2, the drive mechanism 44 drives the two sets of clamping blocks 45 to move closer together, so that the clamping blocks 45 grip the network cable. Then, the second moving frame 41 pulls the network cable from inside the positioning mechanism 2 outward through the clamping blocks 45, thereby adjusting the cutting length of the network cable. After the cutting mechanism 3 cuts the network cable, the drive mechanism 44 drives the clamping blocks 45 to move away from each other. At this time, the cut network cable falls naturally, thereby achieving automatic unloading.

[0029] See Figure 3 and Figure 4 As shown, the second movable frame 41 has two parallel clearance grooves 47 arranged longitudinally on the side facing the positioning mechanism 2, and the clamping block 45 is slidably installed inside the clearance grooves 47; the inner side of the second movable frame 41 is symmetrically provided with two sets of parallel limiting members 48 near the two ends of the clearance grooves 47, and the limiting members 48 are symmetrically provided with two second limiting grooves 481, and the clamping block 45 is longitudinally provided with a second limiting rod 451 that can be installed inside the second limiting groove 481.

[0030] When the two sets of clamping blocks 45 approach each other, the second limiting rod 451 provided on the clamping block 45 can slide longitudinally along the second limiting groove 481, so that the clamping block 45 always remains horizontal during the movement, and avoids the clamping block 45 from shifting when clamping the network cable.

[0031] See Figure 3 and Figure 4 As shown, the second movable frame 41 has two sliding rods 46 inside for mounting the drive mechanism 44. The drive mechanism 44 includes a third movable frame 442 that is slidably mounted on the sliding rods 46 and can reciprocate. Several sliding sleeves 444 are symmetrically arranged on the third movable frame 442. A connecting rod 445 that can drive the clamping block 45 to slide longitudinally along the relief groove 47 is hinged to the sliding sleeve 444. The end of the connecting rod 445 away from the sliding sleeve 444 is hinged to the clamping block 45.

[0032] When the third moving frame 442 moves horizontally, the drive mechanism 44 can slide horizontally along the axis of the slide rod 46 to prevent the third moving frame 442 from deviating during movement. When the third moving frame 442 drives the connecting rod 445 through the sliding sleeve 444, the connecting rod 445 can drive the two sets of clamping blocks 45 to move closer or further apart.

[0033] See Figure 3 and Figure 4 As shown, the drive mechanism 44 includes a fourth electric telescopic member 441 that can drive the third moving frame 442 to move horizontally back and forth. The fourth electric telescopic member 441 is fixed on the side of the second moving frame 41 away from the relief groove 47, and the third moving frame 442 is fixed to the output end of the fourth electric telescopic member 441.

[0034] When the output end of the fourth electric telescopic member 441 extends, the fourth electric telescopic member 441 can drive the third moving frame 442 to slide horizontally along the slide bar 46, so as to avoid displacement when the third moving frame 442 slides.

[0035] See Figure 1 , Figure 2 and Figure 3 As shown, two first sliding grooves 12 are symmetrically arranged on the base 1, and an installation groove 14 is provided between the two first sliding grooves 12 on the base 1. A rotatable lead screw 15 is horizontally installed inside the installation groove 14. A servo motor 13 that can drive the lead screw 15 to rotate is provided inside the base 1. One end of the lead screw 15 can be fixedly connected to the output end of the servo motor 13. A threaded hole 42 that can be installed on the lead screw 15 is provided through the center of the bottom of the second moving frame 41. Two sliders 43 that can slide along the first sliding groove 12 are symmetrically arranged on the side of the threaded hole 42 at the bottom of the second moving frame 41.

[0036] When the servo motor 13 drives the lead screw 15 to rotate, the lead screw 15 drives the second moving frame 41 to move horizontally through the threaded hole 42. While the second moving frame 41 moves, the slider 43 at the bottom of the second moving frame 41 slides along the inside of the first groove 12 to prevent the second moving frame 41 from shifting during movement. This allows the second moving frame 41 to pull the network cable through the clamping block 45 when gripping it, thereby adjusting the length of the network cable.

[0037] See Figure 1 As shown, the positioning mechanism 2 has a first movable frame 22 that can move longitudinally inside. The inner side of the first movable frame 22 is provided with several horizontally installed upper limit rollers 23. The positioning mechanism 2 has lower limit rollers 24 that are provided at equal intervals inside, corresponding to the number of upper limit rollers 23. The top of the positioning mechanism 2 is provided with a first electric telescopic member 21 that can drive the first movable frame 22 to move longitudinally.

[0038] The network cable passes between the upper limit roller 23 and the lower limit roller 24. When the first electric telescopic component 21 drives the first moving frame 22 to move downward, the first moving frame 22 drives the upper limit roller 23 to move downward, so that the upper limit roller 23 and the lower limit roller 24 cooperate to position the network cable and prevent the network cable from getting tangled.

[0039] See Figure 5 and Figure 6 As shown, the base 1 is also provided with a horizontally movable wire cutting mechanism 3. The wire cutting mechanism 3 includes a fixed base 31 and a sliding frame 32 slidably installed inside the fixed base 31. A cutting blade 35 capable of longitudinal reciprocating movement is provided on one side of the sliding frame 32. A blade groove 322 that can be adapted to the cutting blade 35 for wire cutting is provided on the sliding frame 32.

[0040] When the sliding frame 32 slides along the inside of the fixed base 31, the blade groove 322 is at the bottom of the network cable. When the cutting blade 35 moves downward, it can fall into the blade groove 322, so that the cutting blade 35 and the blade groove 322 cooperate to cut the network cable.

[0041] See Figure 5 and Figure 6 As shown, a crossbeam 323 is provided on the top of the sliding frame 32, and a limiting hole 325 is provided at the center of the crossbeam 323. A first limiting rod 351 is provided on the cutting blade 35, which can be vertically installed inside the limiting hole 325. A spring 353 for driving the cutting blade 35 to move upward is installed on the first limiting rod 351, and the bottom of the spring 353 abuts against the upper end face of the crossbeam 323.

[0042] The first limiting rod 351 is installed inside the limiting hole 325, so that the first limiting rod 351 slides inside the limiting hole 325. The spring 353 is installed outside the first limiting rod 351, so that the spring 353 drives the cutting blade 35 upward through the first limiting rod 351, thereby separating the cutting blade 35 from the blade groove 322.

[0043] See Figure 5 and Figure 6 As shown, two slides 324 are symmetrically arranged inside the crossbeam 323. The crossbeam 323 is also provided with a push block 34 that can slide horizontally along the inside of the slide 324. A first limiting groove 342 is provided on the inclined surface of the push block 34. A roller 352 that can travel along the inside of the first limiting groove 342 is provided at the top of the first limiting rod 351.

[0044] When the push block 34 moves horizontally, the roller 352 moves along the inside of the first limiting groove 342. At this time, the roller 352 is squeezed and pushes the first limiting rod 351 to move longitudinally along the limiting hole 325, thereby causing the roller 352 to drive the cutting blade 35 downward.

[0045] See Figure 5 and Figure 6 As shown, a third electric telescopic member 33 is horizontally arranged inside the crossbeam 323 to drive the push block 34 to slide along the slide block 324, and the push block 34 is fixed to the output end of the third electric telescopic member 33.

[0046] By fixing the push block 34 to the output end of the thread cutting mechanism 3, the thread cutting mechanism 3 drives the push block 34 to slide along the slide block 324, thus preventing the push block 34 from shifting when it moves.

[0047] See Figure 5 and Figure 6As shown, a slide rail 312 is horizontally arranged on the fixed base 31, and a second slide groove 321 that can slide along the slide rail 312 is provided at the bottom of the sliding frame 32; two sets of second electric telescopic components 313 for driving the sliding frame 32 to move horizontally are symmetrically arranged on the fixed base 31.

[0048] The second electric telescopic component 313 drives the second sliding groove 321 at the bottom of the sliding frame 32 to slide along the slide rail 312, preventing the sliding frame 32 from shifting when it moves. At this time, the knife groove 322 provided on the sliding frame 32 is at the bottom of the network cable, so that the network cable is placed on the top of the knife groove 322.

[0049] When this utility model is in operation, with the drive mechanism 44 on one side of the positioning mechanism 2, the drive mechanism 44 drives the two sets of clamping blocks 45 to move closer to each other, and the clamping blocks 45 grip the wire. Then, the second moving frame 41 pulls the wire from inside the positioning mechanism 2 outward through the clamping blocks 45 to adjust the cutting length of the wire. After cutting, the drive mechanism 44 drives the clamping blocks 45 to move away from each other, so that the cut wire falls naturally to complete the automatic feeding. During the process of the clamping blocks 45 moving closer to each other, the second limiting rod 451 on the clamping blocks 45 slides longitudinally along the second limiting groove 481 to ensure that the clamping blocks 45 always remain horizontal when moving, preventing the wire from being clamped and deviated. When the third moving frame 442 moves horizontally, the drive mechanism 44 slides horizontally along the sliding rod 46 to avoid deviation. The third moving frame 442 drives the connecting rod 445 through the sliding sleeve 444. The connecting rod 445 drives the two sets of clamping blocks 45 to move closer or further apart. When the output end of the fourth electric telescopic component 441 extends, it drives the third moving frame 442 to slide horizontally along the sliding rod 46 to prevent displacement. Servo motor 13 drives lead screw 15 to rotate. Lead screw 15 drives second moving frame 41 to move horizontally through threaded hole 42. At the same time, bottom slider 43 of second moving frame 41 slides along the inside of first slide groove 12 to avoid deviation. When clamping block 45 grips the network cable, second moving frame 41 pulls the network cable to adjust its length through clamping block 45. Network cable passes between upper limit roller 23 and lower limit roller 24. First electric telescopic component 21 drives first moving frame 22 to move downward. First moving frame 22 drives upper limit roller 23 to move downward. Upper limit roller 23 and lower limit roller 24 cooperate to position network cable and prevent network cable from tangling. When the sliding frame 32 slides along the inside of the fixed base 31, the blade groove 322 is at the bottom of the mesh. The cutting blade 35 can fall into the blade groove 322 when it moves down. The cutting blade 35 and the blade groove 322 cooperate to cut the mesh. The first limiting rod 351 is installed inside the limiting hole 325. The first limiting rod 351 can slide along the limiting hole 325. The spring 353 is installed outside the first limiting rod 351. The first limiting rod 351 drives the cutting blade 35 to move upward and separate the cutting blade 35 from the blade groove 322. When the push block 34 moves horizontally, the roller 352 moves along the inside of the first limiting groove 342. The roller 352 is squeezed and pushes the first limiting rod 351 to move longitudinally along the limiting hole 325, which drives the cutting blade 35 to move downward and fixes the push block 34 at the output end of the wire cutting mechanism 3. The wire cutting mechanism 3 drives the push block 34 to slide along the slide block 324 to avoid deviation. At the same time, the second electric telescopic component 313 drives the second slide groove 321 at the bottom of the sliding frame 32 to slide along the slide rail 312 to avoid deviation. At this time, the knife groove 322 on the sliding frame 32 is at the bottom of the wire and the wire is placed at the top of the knife groove 322.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
