Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and in particular to a cutting device for cable production. Background Technology

[0002] Cables are conductive materials used for power and signal transmission, widely applied in power wiring and communication in various equipment, systems, and buildings. Cables typically consist of multiple conductors, insulation layers, and sheaths, with their design and structure varying depending on the cable's application, operating environment, and safety requirements. Cable cutting devices are indispensable equipment in cable manufacturing, primarily used to cut long cables to the required lengths. The design of these cutting devices directly impacts production efficiency, accuracy, and cost control.

[0003] The prior art publication CN116727567A discloses a cutting device for communication cable production. This technology has an adjustment function, which can adjust the clamping and fixing of cables of different sizes, thereby effectively improving the stability and firmness of cable processing. At the same time, after clamping and fixing, this cutting device can effectively transport and move the cable, thereby effectively improving the efficiency and convenience of cable processing. In addition, this cutting device has a simple structural design, is convenient to use, and has stable and reliable processing operation. Its performance can meet people's needs for cable processing.

[0004] Existing technologies can locate and cut round cables during use, but when cutting flat cables, they lack a suitable positioning structure and cannot provide the same efficient and precise operation, resulting in reduced processing accuracy. In addition, after cutting the cable, burrs will be present at the cross-section of the metal wire inside the cable, and existing technologies are not convenient for automatically removing burrs at the cross-section, thus affecting the appearance and safety of the cable.

[0005] In summary, the existing technology lacks a suitable positioning structure and a technique for burr removal on the cut surface when cutting flat cables. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by providing a cutting device for cable production.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a cutting device for cable production, comprising a processing table, on which two fixed seats are symmetrically arranged, and multiple fixed conveying shafts are rotatably connected to the fixed seats. A movable conveying shaft is also provided on the fixed seats. A fixed frame is fixedly connected to the processing table, and a cutting blade is provided on the fixed frame. An adjustment mechanism is provided on one side of the cutting blade. A swing seat is rotatably connected to the fixed frame, and a cross-section processing seat is slidably fitted on the swing seat. A transmission mechanism is rotatably connected to the cross-section processing seat.

[0008] Preferably, one end of the fixed conveyor shaft extends through the inner wall of the fixed base to the outside and is fixedly connected to a motor A. The motor A is fixedly connected to the fixed base. A limit ring is symmetrically and slidably fitted on the fixed conveyor shaft. An electric push rod A is fixedly connected to one side of the limit ring, and the other end of the electric push rod A is fixedly connected to the fixed conveyor shaft. The limit ring achieves lateral limitation for flat cables of different widths.

[0009] Preferably, a movable base is rotatably connected between the two ends of the movable conveyor shaft. An electric actuator B is fixedly connected to the top of the movable base and is fixedly connected to the fixed base. A motor B is fixedly connected to the movable base, and a drive wheel is fixedly connected to the output end of the motor B. A driven wheel is fixedly connected to the middle of the movable conveyor shaft, and the driven wheel meshes with the drive wheel for transmission. The electric actuator B enables the movable conveyor shaft to vertically limit the movement of flat cables of different thicknesses.

[0010] Preferably, a hydraulic cylinder is fixedly connected to the cutting blade, and the hydraulic cylinder is fixedly connected to the fixed frame. A gear frame is fixedly connected to one side of the cutting blade, and multiple transmission teeth are rotatably connected to the gear frame. A spring is fixedly connected between the transmission teeth and the gear frame. The spring enables unidirectional transmission of the transmission teeth.

[0011] Preferably, the adjusting mechanism includes a reciprocating lead screw, one end of which is rotatably connected to a fixed frame, and an adjusting wheel is fixedly connected to one end of the reciprocating lead screw. The adjusting wheel is movably engaged with a transmission gear. A movable frame is slidably fitted on the outer wall of the reciprocating lead screw. The movable frame is slidably fitted with the fixed frame, and an adjusting rack is fixedly connected to the bottom end of the movable frame.

[0012] Preferably, a transmission wheel is fixedly connected to one end of the swing seat, and the transmission wheel meshes with the adjusting rack for transmission.

[0013] Preferably, multiple grinding wheel shafts are rotatably connected to both sides of the cross-section treatment seat. A gear A is fixedly connected to the top of the grinding wheel shaft. A gear C is meshed between two adjacent gears A. The gear C is rotatably connected to the cross-section treatment seat. Two guide rods are fixedly connected to the bottom of the cross-section treatment seat. The guide rods are slidably engaged with the swing seat.

[0014] Preferably, the transmission mechanism includes a rotating sleeve, which is rotatably connected to the cross-section treatment seat. A gear B is fixedly connected to the top of the rotating sleeve, and the gear B is meshed with two gears A on both sides. A worm is slidably fitted on the inner wall of the bottom end of the rotating sleeve, and a motor C is fixedly connected to the bottom end of the worm. The motor C is fixedly connected to the swing seat.

[0015] Preferably, a worm gear is engaged with one side of the worm gear, and a U-shaped rod is fixedly connected to the worm gear. The U-shaped rod is rotatably connected to the swing seat, and connecting rods are rotatably connected to both ends of the U-shaped rod. The other end of the connecting rod is rotatably connected to the bottom end of the cross-section treatment seat.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By setting a fixed conveyor shaft and a movable conveyor shaft, and by setting two adjustable limit rings on the fixed conveyor shaft and setting an adjustable movable conveyor shaft, it is possible to achieve precise positioning and conveying of flat cables of different sizes when cutting them. This avoids the flat cables from shifting or twisting during the conveying and cutting process. Maintaining accurate positioning of flat cables is especially important for them, which can effectively reduce the risk of cutting errors and poor processing, and improve the processing accuracy and quality of products. By setting up a cross-section processing seat, while the swing seat drives the cross-section processing seat to swing, the transmission mechanism drives the grinding wheel shaft on the cross-section processing seat to rotate, and at the same time drives the cross-section processing seat to reciprocate. This allows the grinding wheel shaft to process the burrs on the metal end of the flat cable cross-section. During cable production and cutting, the burrs on the metal end can be effectively removed, ensuring the flatness of the cable end face, improving the overall quality of the product, reducing the need for manual operation, not only improving production efficiency and quality, but also reducing the complexity of manual operation, and ensuring the stability and safety of the production process. By setting an adjustment mechanism, while the cutting blade moves upward to cut the flat cable, the adjustment mechanism can drive the swing seat to swing, so that the cross-section processing seat can process the burrs on the cut surface of the flat cable. The adjustment mechanism allows the burr processing to be carried out simultaneously with the cable cutting process, which can improve production efficiency, processing accuracy and product quality. Automated and precise operation not only reduces human intervention and errors, but also improves the stability and service life of the equipment, and enhances the flexibility and safety of the production line.

[0019] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figures 1-10 The cable cutting device shown includes a processing table 1, on which two fixed seats 2 are symmetrically arranged.

[0021] like Figure 3 As shown, one end of the fixed conveyor shaft 3 extends through the inner wall of the fixed base 2 to the outside and is fixedly connected to a motor A301. The motor A301 is fixedly connected to the fixed base 2. A limit ring 302 is symmetrically and slidably fitted on the fixed conveyor shaft 3. An electric push rod A303 is fixedly connected to one side of the limit ring 302, and the other end of the electric push rod A303 is fixedly connected to the fixed conveyor shaft 3. The electric push rod A303 drives the connected limit ring 302 to move, thereby limiting the two sides of the flat cable.

[0022] like Figure 4As shown, a movable seat 401 is rotatably connected between the two ends of the movable conveyor shaft 4.

[0023] By setting a fixed conveyor shaft 3 and a movable conveyor shaft 4, and by setting two adjustable limit rings 302 on the fixed conveyor shaft 3 and an adjustable movable conveyor shaft 4, it is possible to achieve precise positioning and conveying of flat cables of different sizes when cutting them, avoiding deviation or twisting of the flat cables during the conveying process. Especially for flat cables, maintaining accurate positioning is crucial, which can effectively reduce the risk of cutting errors and poor processing, and improve product processing accuracy and quality.

[0024] like Figure 5 As shown, a hydraulic cylinder 601 is fixedly connected to the cutting blade 6, and the hydraulic cylinder 601 is fixedly connected to the fixed frame 5. A gear frame 602 is fixedly connected to one side of the cutting blade 6, and multiple transmission teeth 603 are rotatably connected to the gear frame 602. A spring 604 is fixedly connected between the transmission teeth 603 and the gear frame 602. When the cutting blade 6 moves upward, it will cause the cutting blade 6 to drive the gear frame 602 to move. At this time, the transmission teeth 603 on the gear frame 602 will drive the adjusting wheel 702 to rotate.

[0025] like Figure 6 As shown, the adjusting mechanism 7 includes a reciprocating lead screw 701. One end of the reciprocating lead screw 701 is rotatably connected to the fixed frame 5, and an adjusting wheel 702 is fixedly connected to one end of the reciprocating lead screw 701.

The movable frame 703 is slidably fitted to the fixed frame 5, and an adjusting rack 704 is fixedly connected to the bottom end of the movable frame 703. The adjusting wheel 702 drives the connected reciprocating lead screw 701 to rotate, so that the reciprocating lead screw 701 can drive the movable frame 703 to move. At this time, the movable frame 703 will drive the transmission wheel 801 to rotate through the connected adjusting rack 704, so that the transmission wheel 801 can drive the swing seat 8 to swing.

[0026] like Figure 7 As shown, a transmission wheel 801 is fixedly connected to one end of the swing seat 8, and the transmission wheel 801 is engaged with the adjusting rack 704 for transmission.

[0027] like Figure 8As shown, multiple grinding wheel shafts 901 are rotatably connected to both sides of the cross-section treatment seat 9. Gears A902 are fixedly connected to the top of the grinding wheel shafts 901. Gears C904 are meshed between two adjacent gears A902. Gears C904 are rotatably connected to the cross-section treatment seat 9. Two guide rods 903 are fixedly connected to the bottom of the cross-section treatment seat 9. The guide rods 903 are slidably engaged with the swing seat 8.

[0028] like Figure 9 As shown, the transmission mechanism 10 includes a rotating sleeve 1001, which is rotatably connected to the cross-section treatment seat 9. A gear B1002 is fixedly connected to the top of the rotating sleeve 1001, and two gears A902 are respectively meshed on both sides of the gear B1002 for transmission. A worm 1003 is slidably fitted on the inner wall of the bottom end of the rotating sleeve 1001, and a motor C1004 is fixedly connected to the bottom end of the worm 1003. The motor C1004 is fixedly connected to the swing seat 8. The motor C1004 drives the connected worm 1003 to rotate, which in turn drives the gear B1002 connected to the rotating sleeve 1001 to rotate. At this time, the gear B1002 drives the gears A902 on both sides to rotate, and the gears A902 drive the grinding wheel shaft 901 connected to the gears A902 to rotate through the gear C904.

[0029] A worm gear 1003 has a worm wheel 1005 engaged on one side for transmission. A U-shaped rod 1006 is fixedly connected to the worm wheel 1005. The U-shaped rod 1006 is rotatably connected to the swing seat 8. Connecting rods 1007 are rotatably connected to both ends of the U-shaped rod 1006. The other end of the connecting rod 1007 is rotatably connected to the bottom end of the cross-section treatment seat 9. The worm gear 1003 drives the U-shaped rod 1006 connected to the worm wheel 1005 to rotate. At this time, the connecting rods 1007 at both ends of the U-shaped rod 1006 drive the cross-section treatment seat 9 to reciprocate.

[0030] Working principle: When it is necessary to cut the flat cable, first place one end of it on the fixed conveyor shaft 3. Then, use the electric push rod A303 to drive the connected limiting ring 302 to move, so that the two limiting rings 302 limit the two sides of the flat cable. Then, use the electric push rod B402 to drive the moving seat 401 to move down, so that the movable conveyor shaft 4 presses on the upper side of the flat cable. Then, use the motor A301 to drive the fixed conveyor shaft 3 to rotate, and use the motor B403 to drive the drive wheel 404 to rotate, so that the drive wheel 404 drives the movable conveyor shaft 4 connected to the driven wheel 405 to rotate, thereby conveying the flat cable. When it is necessary to cut the flat cable, stop the conveying, use the hydraulic cylinder 601 to drive the connected cutting knife 6 to move down and cut the flat cable. After cutting, use the movable conveying shaft 4 and the fixed conveying shaft 3 on one side to drive the cut end of the flat cable to move a certain distance. Then, when the cutting knife 6 moves up, it will cause the cutting knife 6 to drive the tooth frame 602 to move. At this time, the transmission teeth 603 on the tooth frame 602 will drive the adjusting wheel 702 to rotate. Then the adjusting wheel 702 will drive the connected reciprocating screw 701 to rotate, so that the reciprocating screw 701 can drive the moving frame 703 to move. At this time, the moving frame 703 will drive the transmission wheel 801 to rotate through the connected adjusting rack 704, so that the transmission wheel 801 can drive the swing seat 8 to swing. At this time, the motor C1004 drives the connected worm gear 1003 to rotate, which in turn drives the gear B1002 connected to the rotating sleeve 1001 to rotate. The gear B1002 then drives the gears A902 on both sides to rotate. The gears A902 then drive the grinding wheel shaft 901 connected to the gears A902 to rotate through the gear C904. At the same time, the worm gear 1003 drives the U-shaped rod 1006 connected to the worm wheel 1005 to rotate. The connecting rods 1007 at both ends of the U-shaped rod 1006 drive the cross-section processing seat 9 to move back and forth, thereby removing the burrs on the metal end of the flat cable cross-section.
