DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example: See Figure 1 - Figure 8 , a cable cutting device for communication engineering, comprising a base 1 and a bracket 2 installed on the top of the base 1, and also comprising: A replacement cutting mechanism includes two cutting knives 3 arranged inside a bracket 2 and an adjustment assembly for driving the two cutting knives 3 to move, wherein the adjustment assembly includes a screw rod 10 rotatably connected to the inside of the bracket 2, a slider 11 screwed to the outside of the screw rod 10, and a first motor 12 installed on the outer wall of one side of the bracket 2; the top of the slider 11 is slidably connected to the inner wall of the top of the bracket 2; the output end of the first motor 12 is fixedly connected to one end of the screw rod 10; the tops of the two cutting knives 3 are fixedly connected together; a plurality of hydraulic cylinders 13 are installed at the bottom of the slider 11, and the extended ends of the hydraulic cylinders 13 are fixedly connected to the tops of the cutting knives 3; By controlling the first motor 12 to drive the screw rod 10 to rotate clockwise, the slider 11 is driven to move forward, and then the two cutters 3 are driven to move forward synchronously through the hydraulic cylinder 13, so that the rear cutter 3 moves to the top of the cable, and the hydraulic cylinder 13 is controlled to extend to drive the two cutters 3 to move downward, and the cable is cut by the rear cutter 3. After the cutting is completed, the two cutters 3 are driven to move up and reset by controlling the hydraulic cylinder 13, and then the first motor 12 is controlled to drive the screw rod 10 to rotate counterclockwise, driving the slider 11 to move backward, and the two cutters 3 are driven synchronously by the hydraulic cylinder 13. Move backward, so that the front cutter 3 moves to the top of the cable, and the two cutters 3 are driven to move downward by controlling the extension of the hydraulic cylinder 13, and the cable is cut by the front cutter 3, and this cycle is repeated, and the two cutters 3 are used alternately to cut the cable, thereby avoiding the problem that when the same cutter 3 is continuously cutting the cable, the surface temperature of the cutter 3 increases, which may cause partial melting of the outer protective sheath of the cable, and also avoiding the problem that when the same cutter 3 is continuously cutting the cable, the debris on the surface of the cutter 3 is difficult to clean in time, which may easily scratch the surface protective sheath of the cable.

[0020] The conveying mechanism includes a carriage 42 installed on the top of the base 1, two rollers 4 arranged inside the carriage 42 and a driving assembly for driving the two rollers 4 to rotate. The inner side of the roller 4 is made of rubber material. The cable is driven to move by the friction between the rollers 4 and the outer surface of the cable. When the cable is tightened, if the two rollers 4 are driven to continue to move to the left, the rollers 4 and the cable surface will slide relative to each other. The conveying mechanism also includes a wire channel 43 installed on the top of the base 1; the driving assembly includes two linkage shafts rotatably connected to the inside of the carriage 42 and a second motor 14 installed on the top of the carriage 42; the two rollers 4 are respectively fixedly sleeved on the outside of the two linkage shafts; the outsides of the two linkage shafts are also fixedly sleeved with gears 15, and the two gears 15 are meshed with each other; the output end of the second motor 14 is fixedly connected to the top end of one of the linkage shafts, and the cable to be cut is wound on the outside of the guide roller and is driven by the motor to loosen the wire, so that the two rollers 4 can easily drive the cable to move to the right; The cable is located between the two rollers 4. The second motor 14 is controlled to drive one of the linkage shafts to rotate. The two linkage shafts are rotated through the meshing action of the two gears 15, thereby driving the two rollers 4 to rotate. The friction between the rollers 4 and the cable drives the cable to move from left to right.

[0021] The positioning receiving mechanism includes two turntables 5 arranged inside the base 1, a plurality of receiving shells 6 installed between the two turntables 5, and a plurality of clamping components installed inside the turntable 5. In this embodiment, the number of the receiving shells 6 and the clamping components is two. The top of the base 1 is provided with an opening, and the turntable 5 is located on the inner side of the opening. When the cutter 3 moves down, its right outer wall will fit the left outer wall of the left turntable 5 and move downward to cut the cable. The internal rotation of the base 1 is connected to the drive shaft 16, and the two turntables 5 are fixedly sleeved on the outside of the drive shaft 16; a third motor 17 is installed on the outer wall of one side of the base 1, and the output end of the third motor 17 is connected to the drive shaft 1 6 is fixedly connected; a plurality of wire grooves 18 are provided on the outer walls of the two turntables 5. In this embodiment, the number of wire grooves 18 on the turntable 5 is two, wherein the wire groove 18 on the turntable 5 close to the bracket 2 penetrates the turntable 5, and the two ends of the receiving shell 6 are respectively connected to the wire grooves 18 on the two turntables 5; a pressure sensor 19 is installed on the inner wall of the wire groove 18 in the turntable 5 away from the bracket 2, and the clamping assembly includes two structural grooves provided inside the turntable 5 and an electric push rod 20 installed inside the structural groove; the two structural grooves are symmetrically arranged on both sides of the wire groove 18, and are both connected to the wire groove 18; a clamping block 21 is fixedly connected to the extended end of the electric push rod 20; When the conveying mechanism drives the cable to move to the right, one end of the cable passes through the inside of the wire groove 18 at the top of the left turntable 5 and the inside of the receiving shell 6 located above, and enters the inside of the wire groove 18 at the top of the right turntable 5. When one end of the cable abuts against the pressure sensor 19, the pressure sensor 19 is subjected to pressure and sends a signal to the controller. The controller controls the conveying mechanism to stop conveying the cable, and then controls the two electric push rods 20 at the top of the right turntable 5 to extend, driving the two clamping blocks 21 to approach each other, clamping one end of the cable, and then controlling the cutter 3 to move downward. When the cutter 3 moves downward, it cooperates with the equidistant pull-back mechanism to drive the conveying mechanism to move to the left. The conveying mechanism drives the cable to move to the left synchronously to tighten the cable, thereby avoiding the subsequent cutter 3 from moving the cable. During cutting, the cutting length is not accurate due to the bending of the cable. After the cable is tightened, the two electric push rods 20 at the top of the left turntable 5 are controlled to extend, and the cut end of the cable is clamped by the clamping block 21. After the cutter 3 cuts the cable, the third motor 17 is controlled to drive the drive shaft 16 to rotate 180°, thereby driving the two turntables 5 to rotate 180°, so that the next receiving shell 6 between the two turntables 5 rotates to the right side of the roller 4, ready to receive the cable transported to the right by the conveying mechanism next time. When the turntable 5 drives the cut cable from the inner side of the receiving shell 6 downward, the two electric push rods 20 at the bottom of the turntables 5 on the left and right sides are controlled to shorten, so as to release the clamping of the two ends of the cut cable and put the cut cable into the recycling box 9.

[0022] The equidistant pull-back mechanism comprises a driving block 7 respectively mounted on the top of one side of the two cutters 3 and a driven block 8 mounted on the top of one side of the slide 42. The driven block 8 has an inclined groove 22 and a through groove 23 formed inside. The inclined groove 22 and the through groove 23 are connected. The driving block 7 has a driving groove formed at the bottom. The driving groove is matched with the inclined groove 22. When the driving block 7 moves downward, the driven block 8 is driven to move. Two slide grooves 24 are formed on the top of the base 1. The slide 42 is slidably connected to the inside of the two slide grooves 24. A spring 25 is fixedly connected to the outer wall of one side of the slide 42. The other end of the spring 25 is fixedly connected to the inner wall of the slide groove 24. When the adjustment component drives the two cutters 3 to move forward and backward, the two cutters 3 are alternately driven to move to the top of the slide 42. When the cutters 3 move downward, the drive block 7 is driven to move downward synchronously. When the drive groove abuts against the inclined groove 22, as the drive block 7 continues to move downward, the driven block 8 is driven to move leftward, and the slide 42 and the roller 4 move leftward synchronously. The spring 25 is compressed. When the roller 4 moves leftward, the friction between the two rollers 4 and the cable drives the cable to move leftward synchronously. When the cable is tightened, the roller 4 slides relative to the cable. That is, the roller 4 slides to the left along the outer surface of the cable. When the driving block 7 enters the groove 23, the cutter 3 continues to move downward, but the driven block 8 and the slide 42 stop moving to the left. Therefore, after the cable is tightened, the cutter 3 continues to move downward to cut the tightened cable. After the cable is cut, the cutter 3 is driven to move up and reset. In this process, the slide 42 and the roller 4 are driven to move right and reset through the rebound force of the spring 25 until the lower edge of the driving block 7 is higher than the upper edge of the driven block 8, and then the cutter 3 is driven to move forward or backward.

[0023] The combined processing mechanism is provided with two groups and is respectively installed on the inner walls on both sides of the bracket 2, and is used to clean the debris on the surface of the cutter 3 and cool the cutter 3. The combined processing mechanism includes a scraper block 26 fixed to the inner wall of one side of the bracket 2, an rubbing block 27 arranged below the scraper block 26, and a cooling frame 28 arranged below the rubbing block 27; a through groove 29 is opened inside the scraper block 26, and a scraping groove 30 is opened on the outer wall of the scraper block 26 near the slide 42. The through groove 29 is connected with the scraper groove 30. A slag collecting box 31 is installed on the outer wall of one side of the scraper block 26. The slag collecting box 31 is located below the scraper groove 30 and is used to collect the debris scraped from the outside of the cutter 3. One end of the wiping block 27 is fixedly connected to the inner wall of the bracket 2. An absorbent cotton block 32 is installed inside the wiping block 27. A linear groove is opened inside the absorbent cotton block 32 for passing the cutter 3. One end of the cooling frame 28 is fixedly connected to the inner wall of the bracket 2. A coolant is provided inside the cooling frame 28. The two cutters 3 are driven upward by the adjusting component to reset. At this time, the lower edge of the cutter 3 is at the same level as the lower edge of the scraper groove 30, and the two cutters 3 are driven forward synchronously by the adjusting component. The front cutter 3 enters the interior of the through groove 29 along the inner wall of the scraper groove 30. In this process, the residual slag left when the cutter 3 cuts the cable outside is scraped off in time. The rear cutter 3 moves forward to the top of the slide 42, and the two cutters 3 are driven downward synchronously by the adjusting component. The rear cutter 3 cuts the cable, and the front cutter 3 passes through the absorbent cotton block 32 and enters the cooling frame 28. The surface of the cutter 3 is cooled by the coolant inside the cooling frame 28, and the two cutters 3 are driven upward by the adjusting component. The front cutter 3 passes through the absorbent cotton block 32 when moving upward, and the coolant outside the cutter 3 is sucked out by the absorbent cotton block 32. In this cycle, the replaced cutter 3 is removed and cooled in turn.

[0024] The automatic sorting mechanism includes a recycling box 9 arranged inside the base 1 and a linkage component for driving the recycling box 9 to move back and forth, the linkage component includes a support frame 33 slidably connected to the inner wall of the bottom of the base 1, linkage blocks 34 respectively fixed to the outer walls on both sides of the support frame 33, and a transmission component connected to the linkage block 34; the transmission component includes a worm 35 fixedly sleeved on the outside of the drive shaft 16 and a first transmission shaft 36 and a second transmission shaft 37 rotatably connected inside the base 1, the outside of the first transmission shaft 36 is fixedly sleeved with a worm wheel 38, the worm 35 is meshed with the worm wheel 38, the first transmission shaft 36 and the second transmission shaft 37 are connected by a pulley component 39, the outside of the second transmission shaft 37 is fixedly sleeved with a reciprocating screw 40, the linkage block 34 is screwed to the outside of the reciprocating screw 40, the recycling box 9 is placed inside the support frame 33, and a material taking port 41 is provided on the front of the base 1; When the driving shaft 16 drives the turntable 5 to rotate in sections, the meshing action between the worm 35 and the worm wheel 38 drives the first transmission shaft 36 to rotate, and the transmission connection of the pulley component 39 drives the second transmission shaft 37 to rotate synchronously, and the reciprocating screw 40 rotates accordingly. When the reciprocating screw 40 rotates, it drives the linkage block 34 to move back and forth in sections, thereby driving the recycling box 9 to move back and forth in sections synchronously through the support frame 33, thereby achieving the effect of adjusting the cable receiving position of the recycling box 9 according to the cutting progress of the cable, and improving the effect of automatic sorting of the cables after cutting. After the recycling box 9 is full of cables, the recycling box 9 can be taken out from the inside of the base 1.
