Description

Technical Field

[0001] The invention relates to the technical field of cable outer sheath cutting, in particular to a cable outer sheath stripping device and a use method thereof. Background Art

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer, which transmit electricity or information from one place to another. The service life of cables is mostly 10-15 years. At the end of the service life of the cable, the metal core in the cable can still be recycled, so it is often necessary to use cable outer sheath stripping equipment to recycle it.

[0003] The patent with application number 202010704491.3 discloses a cable outer sheath stripping device for power cables, including a winding mechanism, a conveying mechanism, a transverse cutting mechanism, a longitudinal cutting mechanism, and a raw material collection mechanism. It has the function of winding the cable on a winding column, cutting the cable outer sheath laterally, and cutting the upper side of the cable outer sheath. The device can tilt out the cut outer sheath.

[0004] However, the existing cable outer sheath stripping equipment still has certain defects when used, especially the cable outer sheath stripping equipment used in some special environments, for example: for the cable outer sheath stripping equipment buried underground, the existing cable outer sheath stripping equipment used in such environments, because the cable is buried underground for a long time, there is often a situation where the cable outer sheath and the metal inner core are tightly adhered, which makes it easy for the outer sheath to break when stripping the outer sheath. Secondly, when the cable is taken out from the underground, mud often adheres to the surface of the outer sheath. If the mud condenses on the surface of the cable outer sheath, it will make it more difficult to strip the outer sheath. When stripping the outer sheath, the condensed mud will act as an obstacle.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention loosens the soil adhered to the cable outer sheath by the rolling of the roller, and can also loosen the adhesion between the cable outer sheath and the metal inner core caused by the cable being buried underground for a long time, thereby facilitating the subsequent cutting of the cable outer sheath; after the cable outer sheath is cut, it enters the stripping ring, the outer sheath passes through the outside of the stripping ring, and the metal inner core passes through the inner ring of the stripping ring into the guide roller, the stripping ring can effectively strip the metal inner core and the outer sheath, and the loosening effect of the roller on the outer sheath and the metal inner core can also be further promoted.

[0021] 2. The present invention provides an annular groove. After entering the annular groove, the water flow will enter the nozzle through the through hole, and then be sprayed on the surface of the outer sheath of the cable. On the one hand, it can moisten the mud adhering to the outer sheath of the cable, which is convenient for the subsequent cleaning of the mud. On the other hand, it can also wash away the dust or debris adhering to the surface of the cable, promote the cleaning of the outer sheath, and thus achieve the purpose of facilitating the subsequent centralized, rapid and harmless treatment of the outer sheath.

[0022] 3. The present invention adopts the setting of the water-swellable sponge ring, which can absorb the moisture on the surface of the cable outer sheath on the one hand, and wipe the residual stains on the cable outer sheath on the other hand. The water-swellable sponge ring will expand after absorbing water, thereby making the contact between the water-swellable sponge ring and the cable outer sheath more complete. As the water-swellable sponge ring absorbs water, the cable outer sheath will be cleaned more thoroughly, preventing mud from condensing on the surface of the outer sheath, making it difficult to peel off the outer sheath.

[0023] 4. The present invention can effectively prevent the cable outer sheath from being damaged by harder materials adhering to the cable outer sheath through the cleaning effect of the water-absorbing and expanding sponge ring and the limiting ring, thereby further ensuring the service life of the cutting knife. The elastic force exerted by the spring on the cutting knife through the ring plate can also prompt the cutting knife to cut off the cable outer sheath. The positioning ring and the limiting ring guide the cable to ensure a uniform state of the cable outer sheath after it is cut, thereby facilitating the winding and collection of the cable outer sheath, and avoiding the situation in which the cable outer sheath is broken into multiple sections due to uneven cutting of the cable outer sheath, resulting in a large amount of accumulation of the cable outer sheath on the cutting device.

When the water sprayed by the nozzle 27 falls on the inclined plate 16, the inclined surface of the inclined plate 16 can also splash part of the falling water onto the surface of the outer sheath of the cable wound around the feeding roller 18.

[0042] As a technical optimization solution of the present invention, Figure 2 , Figure 5 As shown, the tops of the two side plates 2 are fixedly connected with vertical plates, and the opposite sides of the two vertical plates are fixedly connected with cross bars. The ends of the two cross bars away from the two vertical plates are fixedly connected to the two sides of the fan 10. The fan 10 is located directly above the cutting ring 9 and the fan 10 is tilted above the cutting ring 9. The fan 10 faces the water-absorbing and expanding sponge ring 29. A rectangular groove is opened at the center of the end of the side plate 2 away from the feeding roller 18. An electric slider 14 is slidably connected in the rectangular groove. The opposite sides of the two electric sliders 14 are rotatably connected with winding rollers 13. A motor is provided at one end of the winding roller 13. The winding roller 13 is fixedly connected to the output shaft of the motor by pins and bolts. The fixed connection between the winding roller 13 and the output shaft of the motor is a prior art, similar to the connection between a diesel engine and a pulley, and will not be disclosed in detail here.

[0043] As a technical optimization solution of the present invention, Figure 1 , Figure 5 and Figure 6As shown, both ends of the guide roller 11 are fixedly connected with a rotating shaft 39, the rotating shaft 39 is rotatably sleeved in the mounting plate 40, the end of the mounting plate 40 away from the rotating shaft 39 is fixedly connected to the inner wall of the side plate 2, the top and bottom of the stripping ring 31 are provided with guide rollers 11, the top and bottom of the end of the side plate 2 away from the feeding roller 18 are rotatably connected with an electric rotating shaft 15, the winding disk 12 is fixedly connected to one end of the electric rotating shaft 15, and the four winding disks 12 are located on the opposite side of the two side plates 2. The electric rotating shaft 15 will reel the cut outer skin but not pull it, thereby preventing the outer skin from being pulled and broken when the electric rotating shaft 15 rotates.

[0044] A method for using a cable outer sheath stripping device, the method comprising the following steps:

[0045] Step 1: Place the feeding roller 18 wound with the waste cable on the top of the arc-shaped placement plate 5, extend the telescopic rod 4 until the arc-shaped placement plate 5 abuts against the arc-shaped limit plate 6, so that the bearing is located between the arc-shaped placement plate 5 and the arc-shaped limit plate 6;

[0046] Step 2: Take one end of the cable off the feeding roller 18, pass it through the limiting ring 7, the positioning ring 8 and the cutting ring 9 in sequence, then pass the four cable outer sheaths cut by the cutting knife 38 into strips through the outside of the stripping ring 31 respectively, pass the metal core of the cable through the inside of the stripping ring 31, and the stripping ring 31 strips the outer sheath from the cable;

[0047] Step 3: Pass the stripped metal core through the two guide rollers 11 and then wrap it around the winding roller 13. Wrap the four strip outer sheaths around the winding reel 12 respectively. Cut the outer sheath of the cable by rotating the winding roller 13 and the electric shaft 15.

[0048] When the present invention is in use, the feeding roller 18 wound with the waste cable is placed on the top of the arc placement plate 5, and the telescopic rod 4 is extended to the arc placement plate 5 and abuts against the arc limit plate 6, so that the bearing is located between the arc placement plate 5 and the arc limit plate 6. In this process, when the feeding roller 18 wound with the waste cable is placed on the top of the arc placement plate 5, the arc placement plate 5 can effectively prevent the feeding roller 18 from sliding off the arc placement plate 5, and when installing the feeding roller 18 on the arc placement plate 5, the technician only needs to push the feeding roller 18, and push the feeding roller 18 to the top of the arc placement plate 5, so that the bearing is located directly above the arc placement plate 5, which effectively reduces the expenditure of human resources and makes the installation of the feeding roller 18 faster and more convenient. As the telescopic rod 4 extends, the arc-shaped placement plate 5 abuts against the arc-shaped limit plate 6, so that the arc-shaped placement plate 5 and the arc-shaped limit plate 6 form a circular ring on the outer ring of the bearing, which can have a good limiting effect on the loading roller 18 through the bearing, and at the same time, will not affect the rotation of the loading roller 18.

[0049] One end of the cable is removed from the feeding roller 18, and passed through the limiting ring 7, the positioning ring 8 and the cutting ring 9 in sequence. Then, the four strips of the cable outer sheath cut by the cutting knife 38 are passed through the outside of the stripping ring 31 respectively, and the metal core of the cable is passed through the inside of the stripping ring 31. The stripping ring 31 strips the outer sheath from the cable. The stripped metal core is passed between the two guide rollers 11, and then wound on the winding roller 13. The four strips of outer sheath are respectively wound on the winding drum 12, and the outer sheath of the cable is cut by the rotation of the winding roller 13 and the electric shaft 15.

[0050] Then turn on the fan 10, the electric shaft 15 and the motor on the side of the winding roller 13. The motor drives the winding roller 13 to rotate, so that the metal core inside the cable can be wound around the winding roller 13, and the cable on the feeding roller 18 is pulled by the tension provided by the metal core. The damping in the bearing can effectively prevent the feeding roller 18 from continuously rotating due to the inertia of rotation, thereby preventing the feeding roller 18 from excessively rotating and causing the cable wound on the feeding roller 18 to detach too much from the feeding roller 18, thereby ensuring the cutting efficiency of the cutting knife 38 on the outer sheath of the cable.

[0051] Since the cable is wound around the feeding roller 18, the contact point between the cable and the feeding roller 18 will "swing left and right" during the process of the cable being transported on the device, thereby applying a "swinging left and right" force to the limiting ring 7. When the cable passes through the limiting ring 7, the surface of the cable outer sheath will abut against the roller 28. In the process of the cable passing through the limiting ring 7, the roller 28 will apply a force to the cable outer sheath through the "swinging left and right" movement of the cable, thereby enabling the roller 28 to apply a force to the surface of the cable outer sheath. Through the rolling of the roller 28, the soil adhered to the cable outer sheath becomes loose, and at the same time, the adhesion between the cable outer sheath and the metal inner core caused by the cable being buried underground for a long time can also be loosened, thereby facilitating the subsequent cutting of the cable outer sheath.

[0052] When the cable "sways left and right", it will also drive the limiting ring 7 to move laterally. When the limiting ring 7 moves laterally, it will slide on the fixed plate 23 through the guide slider 24. When the limiting ring 7 slides laterally, it will drive the piston plate 20 to move toward the limiting ring 7 or away from the limiting ring 7. When the piston plate 20 moves toward the limiting ring 7, the limiting ring 7 will draw water from the water tank 3 through the piston plate 20. The water flows into the piston cylinder 17 through the water inlet pipe 19. When the piston plate 20 moves away from the limiting ring During the movement in the 7-direction, the water flow in the piston cylinder 17 will flow into the annular groove 25 under the squeezing of the piston plate 20. After entering the annular groove 25, the water flow will enter the nozzle 27 through the through hole 26, and then can be sprayed on the outer sheath surface of the cable. On the one hand, it can moisten the mud adhering to the outer sheath of the cable, which is convenient for the subsequent cleaning of the mud. On the other hand, it can also wash away the dust or debris adhering to the surface of the cable, promote the cleaning of the outer sheath, and thus achieve the purpose of facilitating the subsequent centralized and rapid harmless treatment of the outer sheath.

[0053] When the limiting ring 7 cleans the cable outer sheath through the two piston cylinders 17, the reaction force exerted by the piston plate 20 on the limiting ring 7 by squeezing the water flow can also limit the sliding of the limiting ring 7 on the fixing plate 23, so that the limiting ring 7 is always in a position relatively to the center of the top of the bottom plate 1, thereby limiting the relative position of the cable outer sheath entering the positioning ring 8, so that the cable outer sheath can maintain a relatively horizontal position to enter the positioning ring 8, preventing the cable from entering the positioning ring 8 at too large an angle and causing the cable to get stuck, thereby ensuring smooth cutting of the cable outer sheath.

[0054] When the cable enters the positioning ring 8, the outer sheath of the cable will first abut against the scraper ring 30. The cross-section of the scraper ring 30 is an isosceles triangle. On the one hand, the scraper ring 30 can guide the cable so that the cable passes through the positioning ring 8 within a certain angle. On the other hand, the scraper ring 30 can also scrape off a large amount of dust and adhered soil on the surface of the outer sheath of the cable, further ensuring the cleaning of the outer sheath of the cable. When the cable leaves the positioning ring 8 and slides with the water-absorbing and expanding sponge ring 29, the water-absorbing and expanding sponge ring 29 will absorb the moisture on the surface of the outer sheath of the cable on the one hand, and wipe the stains remaining on the outer sheath of the cable on the other hand. The water-absorbing and expanding sponge ring 29 will expand after absorbing water, thereby making the abutment between the water-absorbing and expanding sponge ring 29 and the outer sheath of the cable more complete. As the water-absorbing and expanding sponge ring 29 absorbs water, the cleaning of the outer sheath of the cable will be more thorough, and the drying of the outer sheath of the cable can also be ensured. In this process, the fan 10 always blows the water-absorbing and expanding sponge ring 29. On the one hand, it can promote the rapid drying of the cable outer sheath coming out of the water-absorbing and expanding sponge ring 29, and on the other hand, it can also prevent the water sprayed by the nozzle 27 from splashing onto the cutting ring 9, thereby causing the cutting knife 38 to rust, effectively extending the service life of the cutting knife 38. Secondly, during the cleaning process of the cable outer sheath, the sewage will fall on the inclined plate 16. After falling on the inclined plate 16, the sewage will move toward the end of the bottom plate 1 away from the winding roller 13. In this process, the wind blown by the fan 10 can effectively promote the sewage to flow to the end of the bottom plate 1 away from the winding roller 13. The sewage flows to the end of the bottom plate 1 away from the winding roller 13, that is, the end flowing to the upper feed roller 18. The wind blown by the fan 10 can also blow the water droplets splashed by the water vapor or sewage falling on the inclined plate 16 onto the feeding roller 18. The water vapor or water droplets fall on the cable outer sheath wound on the feeding roller 18, which can pre-humidify the cable outer sheath, further promoting the wetting effect of the nozzle 27 on the cable outer sheath.

[0055] After the cable leaves the water-swellable sponge ring 29, it will horizontally enter the cutting ring 9. The cutting knife 38 arranged on the cutting ring 9 can effectively cut the outer sheath of the cable into multiple long strips, and through the cleaning effect of the water-swellable sponge ring 29 and the limiting ring 7, it can effectively prevent the outer sheath of the cable from being damaged by harder substances adhering to the outer sheath of the cable, further ensuring the service life of the cutting knife 38. The elastic force applied by the spring 36 to the cutting knife 38 through the ring plate 37 can also prompt the cutting knife 38 to cut off the outer sheath of the cable. Through the guiding effect of the positioning ring 8 and the limiting ring 7 on the cable, the uniform state of the outer sheath of the cable can be ensured after it is cut off, which facilitates the winding and collection of the outer sheath of the cable, avoiding the situation where the outer sheath of the cable is broken into multiple sections due to uneven cutting of the outer sheath of the cable, resulting in a large amount of accumulation of the outer sheath on the cutting device.

[0056] After the cable outer sheath is cut, it enters the stripping ring 31, the outer sheath passes through the outside of the stripping ring 31, and the metal inner core passes through the inner ring of the stripping ring 31 and enters the guide roller 11. The stripping ring 31 can effectively strip the metal inner core and the outer sheath. The loosening effect of the roller 28 on the outer sheath and the metal inner core can also further promote the stripping effect of the stripping ring 31 on the outer sheath and the metal inner core.

[0057] The setting of the guide roller 11 can play a guiding and dividing role for the metal inner core and the outer skin. The outer skin will not come into contact with the metal inner core after being guided by the guide roller 11, so that the outer skin can be effectively wound on the winding disk 12. The metal inner core can be effectively wound on the winding roller 13 after being guided by the guide roller 11. In the process of the winding roller 13 winding the metal inner core, the guide roller 11 can effectively limit the metal inner core, so that the metal inner core is in a horizontal state, to prevent the outer diameter of the contact point between the metal inner core and the winding roller 13 from increasing due to the gradual increase in the length of the metal inner core wound on the winding roller 13, resulting in the force on the metal inner core being offset, thereby ensuring that the force on the metal core when entering the cutting ring 9 is a horizontal force, thereby ensuring that the cutting knife 38 cuts the outer skin evenly, to prevent the outer skin from breaking during cutting.
