As shown in fig. 1 to 12, the present invention provides a stripping device for a communication cable 000, which includes a rack 100, wherein one end of the rack 100 is installed with a cable drum 110, and the other end is installed with a core drum 120, and of course, the cable drum 110 and the core drum 120 are respectively driven by respective driving motors (not shown in the drawings), and the cable drum 110 is respectively driven to release the cable, and the core drum 120 is driven to wind the core.

The first heating unit 200 is used to heat the cable 000. Specifically, for heating the outer skin 001 of the cable 000 to be peeled, the outer skin 001 of the cable 000 becomes soft when heated, which facilitates the cutting of the outer skin 001 by the cutting unit 300. Specifically, the first heating unit 200 is installed at a side of the cable drum 110 facing the core drum 120, and includes a first heating sleeve 210, a first heating wire 220, and a first heat insulating layer 230.

The first heating sleeve 210 is fixedly mounted on the rack 100, and the first heating sleeve 210 is provided with a first through hole along the axial line thereof, so that the cable 000 to be stripped is heated by the first heating sleeve 210 while being transmitted from the first through hole.

The first heating wire 220 is fixedly wound around the outer circumference of the first heating sleeve 210. This allows the first heating sleeve 210 to be heated at the first heating wire 220, thereby heating the cable 000.

The number of the first heat preservation layers 230 is two, the two first heat preservation layers 230 are respectively and fixedly installed at two ends of the first through hole, namely the first heating sleeve 210, and the first heat preservation layers 230 are formed by splicing a plurality of fan-shaped structures. This facilitates the cable 000 to enter the first through-hole for heating from the first insulating layer 230 at one end of the first through-hole and then to exit the first through-hole from the first insulating layer 230 at the other end of the first through-hole.

The cutting unit 300 is used to cut the sheath 001 of the cable 000 heated by the first heating unit 200. Thus, after the cutting unit 300 performs the preliminary cutting of the sheath 001, the pressing unit 500 can easily separate the sheath 001 and the core 002 of the cable 000 along the cutting path. Thereby facilitating the peeling of the sheath 001 and the core 002 of the cable 000 by the peeling unit 700 thereafter. Specifically, the cutting unit 300 is installed at a side of the first heating unit 200 facing the core drum 120, and includes a wire guide shaft 310, an adjustment shaft 320, a motor mount 330, a first motor 340, an adjustment slider 350, an adjustment slider 360, a cutting edge 370, a connection rod 380, and a return spring 390.

The wire guide shaft 310 is fixedly mounted on the frame 100, and the wire guide shaft 310 is provided with a fourth through hole along the axial line thereof. Thus, the cable 000 comes out of the first heating unit 200 and enters the fourth through hole, and the cable 000 is transmitted through the fourth through hole.

The adjusting shaft 320 is sleeved on the wire guiding shaft 310 and is in threaded connection with the wire guiding shaft 310, specifically, an inner circumferential surface of the adjusting shaft 320 is provided with an inner thread, an outer circumferential surface of a portion, matched with the adjusting shaft 320, of the wire guiding shaft 310 is provided with an outer thread, and the adjusting shaft 320 and the wire guiding shaft 310 are in threaded connection through the inner thread and the outer thread. And a driven gear is installed at an end of the adjusting shaft 320 facing the first heating unit 200.

The motor mounting base 330 is sleeved on the adjusting shaft 320 and is rotatably connected with the adjusting shaft 320. The first motor 340 is fixedly installed on the motor installation base 330, and a driving gear is arranged on a power output shaft of the first motor 340 and is meshed with a driven gear. Therefore, the first motor 340 drives the adjusting shaft 320 to rotate, the adjusting shaft 320 can carry the motor to make linear motion along the wire guiding shaft 310 under the effect of the threaded connection between the adjusting shaft 320 and the wire guiding shaft 310, and then the motion direction of the adjusting shaft 320 can be changed by changing the rotation direction of the first motor 340, so that the adjusting shaft 320 makes reciprocating linear motion on the wire guiding shaft 310.

The adjusting slider 350 is disposed on the wire guiding shaft 310 and slidably connected to the wire guiding shaft 310, that is, the adjusting slider 350 can only slide along the length direction of the wire guiding shaft 310 but cannot rotate around the axis of the wire guiding shaft 310. Preferably, the adjustment slider 350 is also connected to the motor mount 330, such that the rotation of the motor mount 330 can be limited by the adjustment slider 350. The adjusting slide 350 is located at an end of the adjusting shaft 320 facing away from the first heating unit 200, is rotatably connected to the adjusting shaft 320, and is movable along with the movement of the adjusting shaft 320. Specifically, one end of the adjusting shaft 320 facing the adjusting slide 350 is provided with a first connecting portion, the first connecting portion is a sliding groove disposed around an axial line of the adjusting shaft 320, one end of the adjusting slide 350 facing the adjusting shaft 320 is provided with a second connecting portion, and the second connecting portion is slidably clamped in the first connecting portion, so that the adjusting slide 350 is not driven to rotate by rotation of the adjusting shaft 320, but the adjusting shaft 320 drives the adjusting slide 350 to move linearly on the guiding shaft 310.

The inner side of the adjusting slide 350, which is far from the end of the first heating unit 200, is provided with four sliding grooves which are uniformly distributed around the axis of the wire guiding shaft 310, and one sides of the four sliding grooves, which face the axis of the adjusting shaft 320, deviate from the axis of the wire guiding shaft 310 from one end of the adjusting slide 350, which is close to the adjusting shaft 320, to the other end. That is, the four sliding grooves are inclined from one end of the adjusting slider 350 facing the adjusting shaft 320 to the other end, and the farther from the adjusting shaft 320, the farther from the axis of the adjusting shaft 320 the side of the sliding grooves facing the axis of the adjusting shaft 320.

The number of the adjusting slide blocks 360 is four, and the four adjusting slide blocks 360 are respectively installed in the four sliding grooves in a sliding mode. Specifically, the two sides of the adjusting slider 360 are provided with limiting parts, and the two sides of the sliding groove are provided with limiting grooves, so that the adjusting slider 360 cannot turn over in the sliding groove.

The number of the cutting blades 370 is four, and the four cutting blades 370 are respectively fixedly installed at one sides of the four adjusting sliders 360 facing the axial line of the wire guide shaft 310 and slidably connected with the wire guide shaft 310. In the sliding connection, the cutting blade 370 may move toward or away from the axis of the wire guide shaft 310, rather than along the length of the wire guide shaft 310.

The number of the connecting rods 380 is four, and the four connecting rods 380 are respectively fixedly installed on one sides of the four adjusting sliders 360, which are away from the axis of the wire guide shaft 310, and are movably connected with the adjusting slide base 350. Specifically, the adjusting slide 350 is provided with a slide hole on one side of the slide groove away from the axis of the adjusting shaft 320, and the connecting rod 380 is movably connected with the adjusting slide 350 through the slide hole.

The number of the return springs 390 is four, and the four return springs 390 are respectively sleeved on the four connecting rods 380. And in a natural state, the return spring 390 has a tendency to move the adjustment slider 360 away from the axis of the lead shaft 310.

Therefore, when the cutting device is used, the adjusting shaft 320 can be driven to rotate by the first motor 340, the adjusting shaft 320 is in threaded connection with the wire guide shaft 310, the adjusting shaft 320 rotates and moves linearly along the wire guide shaft 310, the adjusting slide seat 350 moves linearly, the position of the adjusting slide block 360 in the sliding groove is changed, the sliding groove is obliquely arranged, the position of the adjusting slide block 360 in the sliding groove is changed, the distance between the adjusting slide block 360 and the axial lead of the wire guide shaft 310 is changed, the distance between the cutting edge 370 and the axial lead of the wire guide shaft 310 is changed, and cables 000 with different diameters can be cut. Meanwhile, the cutting unit 300 of this structure can simultaneously change the distances between the four cutting blades 370 and the axis of the wire guide shaft 310 by changing the rotation direction of the first motor 340 through the first motor 340, which is convenient and helps to ensure that the wire 000 always passes along the axis of the wire guide shaft 310.

The cooling unit 400 is used to cool the cable 000 cut by the cutting unit 300 so as to separate the sheath 001 and the core 002 of the cable 000 when the pressing unit 500 presses the cable 000. Specifically, since the sheath 001 of the cable 000 is cooled by the cooling unit 400, the sheath 001 of the cable 000 is easily separated from the core 002 when the pressing unit 500 presses because the amount of deformation of the sheath 001 after cooling becomes small and a plurality of slits are cut after being cut by the cutting unit 300. Specifically, the cooling unit 400 is disposed at a side of the cutting unit 300 facing the core drum 120, and includes a cooling sleeve 410 and a third insulation layer 420.

The cooling sleeve 410 is fixedly mounted on the rack 100, the cooling sleeve 410 is provided with a third through hole along the axial line thereof, and the cable 000 is transmitted through the third through hole. The cooling sleeve 410 has a cooling medium chamber, an inlet of which is communicated with the cooling medium delivery pipe and an outlet of which is communicated with the cooling medium return pipe. Like this microthermal coolant medium gets into the coolant medium chamber from the import through coolant medium pipeline, cools off cooling sleeve 410, then flows out from the export and flows back in getting into the coolant medium return line, after cooling, the rethread coolant medium pipeline gets into the coolant medium intracavity, and is so repeated.

The number of the third insulating layers 420 is two, the two third insulating layers 420 are fixedly installed at two ends of the third through hole, namely the cooling sleeve 410, and the third insulating layers 420 and the first insulating layer 230 are formed by splicing a plurality of fan-shaped structures, so that the third through hole can be insulated, and the cables 000 can conveniently pass through the third insulating layers 420 to enter or penetrate out of the third through hole.

The pressing unit 500 serves to press the cable 000 cooled by the cooling unit 400 to separate the core 002 and the sheath 001 of the cable 000. Since the outer skin 001 of the cable 000 is cooled by the cooling unit 400 after being cut by the cutting unit 300, the outer skin 001 of the cable 000 is naturally separated to both sides of the core 002 of the cable 000 along the cut of the cutting unit 300 by the pressing unit 500, thereby separating the outer skin 001 of the cable 000 from the core 002. Specifically, the pressing unit 500 is installed at a side of the cooling unit 400 facing the core drum 120, and includes a pressing roller mount 510, a pressing roller 520, and a second motor 530.

The number of the squeeze roll mounting bases 510 is two, and the two squeeze roll mounting bases 510 are arranged oppositely and are connected with the machine frame 100 through two first adjusting hydraulic cylinders 540 respectively. Thus, the distance between the two squeeze roller mounts 510 and thus the distance between the two squeeze rollers 520 can be adjusted by adjusting the extension and contraction of the first adjusting hydraulic cylinder 540, so that the squeezing of cables 000 having different diameters can be realized.

The number of the squeeze rollers 520 is two, the two squeeze rollers 520 are respectively installed at one opposite side of the two squeeze roller installation seats 510 and are respectively rotatably connected with the two squeeze roller installation seats 510, and one end of each squeeze roller 520 is provided with a driven pulley.

The number of the second motors 530 is two, the two second motors 530 are respectively and fixedly mounted on the two squeeze roller mounting seats 510, and a driving belt wheel is arranged on a power output shaft of the second motors 530 and is in transmission connection with a driven belt wheel through a conveying belt. Specifically, the two second motors 530 drive the two pressing rollers 520 to rotate in opposite directions, so that the second motors 530 drive the rotation of the pressing rollers 520, thereby pressing and transmitting the cable 000.

The second heating unit 600 is used for heating the cable 000 extruded by the extrusion unit 500, because the cooled cable 000 has a small deformation amount of the outer sheath 001, i.e. becomes brittle, and is easily broken in the separation process, and the cooled cable 000 has a large adhesion force between the outer sheath 001 and the core 002, so that the outer sheath 001 of the cable 000 is more easily broken, and a small amount of the outer sheath 001 still adheres to the core 002. However, after the second heating unit 600 heats the cable, the expansion rates of the sheath 001 and the core 002 of the cable 000 are different, and thus the adhesive force is reduced, and the sheath 001 of the cable 000 becomes soft by heating and is not easily broken, so that the sheath 001 and the core 002 of the cable 000 are easily separated. Specifically, the second heating unit 600 is installed at a side of the pressing unit 500 facing the core reel 120, and includes a second heating sleeve 610, a second heating wire 620, and a second insulation layer 630.

The second heating sleeve 610 is fixedly mounted on the rack 100, and the second heating sleeve 610 is provided with a second through hole along the axial line thereof, so that the cable 000 to be stripped is heated by the second heating sleeve 610 while being transmitted from the second through hole. The second heating wire 620 is fixedly wound around the outer circumference of the second heating sleeve 610. This allows the second heating sleeve 610 to be heated at the second heating wire 620, thereby heating the cable 000.

The number of the second insulating layers 630 is two, the two second insulating layers 630 are respectively and fixedly installed at two ends of the second through hole, namely, the second heating sleeve 610, and the second insulating layers 630 are formed by splicing a plurality of fan-shaped structures. This facilitates the entry of the cable 000 into the second through-hole for heating from the second insulating layer 630 at one end of the second through-hole, and then exits the second through-hole from the second insulating layer 630 at the other end of the second through-hole.

The peeling unit 700 is used for peeling the sheath 001 and the core 002 of the cable 000 heated by the second heating unit 600. After the second heating unit 600 heats the sheath 001 and the core 002 of the cable 000, the sheath 001 of the cable 000 becomes soft while the adhesive force between the sheath 001 and the core 002 of the cable 000 becomes small. The peeling unit 700 can easily peel the sheath 001 and the core 002 of the cable 000. Specifically, the peeling unit 700 is installed at a side of the second heating unit 600 facing the core reel 120, and includes a peeling rail 710, a peeling blade 720, and a second adjusting hydraulic cylinder 730.

Wherein the two peeling rails 710 are oppositely disposed. Specifically, the peeling rail 710 is a longitudinally disposed channel. Two peeling blades 720 are respectively installed on the tops of the opposite sides of the two peeling rails 710.

The second adjusting hydraulic cylinder 730 is used for driving the two peeling rails 710 to move close to or away from each other, and specifically, both ends of the second adjusting hydraulic cylinder 730 are respectively connected with the machine frame 100 and the peeling rails 710, so that the distance between the peeling blades 720 can be controlled by controlling the extension and contraction of the second adjusting hydraulic cylinder 730, and thus the cables 000 with different diameters can be peeled.

In use, the cable 000 passes between the two stripping blades 720, and the sheath 001 of the cable 000 is forced to separate from the core 002 by the two stripping blades 720 and then slides along the stripping track 710 into the sheath 001 recycling bin.

The burning unit 800 is used for burning the core 002 of the cable 000 stripped by the stripping unit 700. Since there is a possibility that a part of the sheath 001 of the cable 000 is adhered to the core 002 after the peeling unit 700 peels the cable 000, the sheath 001 may be burned against a small amount of the sheath 001 by the burning unit 800 to be removed. Specifically, the burning unit 800 is installed at a side of the peeling unit 700 facing the core drum 120, and includes two oppositely disposed torches 810, an air inlet of the torches 810 being communicated with a gas supply system.

When the cable 000 is used, the cable passes between the two flame guns 810, and a small amount of the sheath 001 adhered to the surface of the core 002 is burnt and cleaned under the action of fire sprayed from the flame guns 810.

The cleaning unit 900 is used to clean the core 002 of the cable 000 burned by the burning unit 800. Generally, the burning unit 800 burns off only a small portion of the sheath 001 after the cable 000 is burned, but the adhesion between the sheath 001 and the wire core 002 is further reduced, and most of the sheath 001 still adheres to the surface of the wire core 002 with a small adhesion force. So that the cleaning unit 900 can easily clean it from the wire core 002. Specifically, the cleaning unit 900 is installed at a side of the burning unit 800 facing the core reel 120, and includes an installation block 910 and a cleaning foam 920.

The number of the mounting blocks 910 is two, the two are oppositely arranged, and the two mounting blocks 910 are respectively connected with the frame 100 through the third adjusting hydraulic cylinders 930. The number of the cleaning foam 920 is two, and the two cleaning foams 920 are respectively and fixedly arranged at the opposite sides of the two mounting blocks 910. Because the cleaning foam 920 has good compressibility, the core 002 of the cable 000 can be completely wrapped under the action of the two cleaning foams 920 which are oppositely arranged, so that the core 002 of the cable 000 can be cleaned.

When the cleaning device is used, the distance between the two cleaning foam 920 is adjusted by controlling the extension and the contraction of the third adjusting hydraulic cylinder 930, so that the wire cores 000 with different diameters can be cleaned.

Preferably, the stripping device also comprises a computer, and the distance between the cutting edge and the axial lead of the wire shaft, the distance between the two squeezing rollers, the distance between the two stripping edges and the distance between the two cleaning foams are automatically controlled by inputting the diameter, the skin thickness, the wire core diameter and other information of the cable to be stripped in the calculation. Specifically, the computer controls the distance by controlling the first motor, the first adjusting hydraulic cylinder, the second adjusting hydraulic cylinder and the third adjusting hydraulic cylinder.
