Description

Technical Field

[0001] The invention relates to the field of power transmission copper conductor stripping, in particular to a power transmission copper conductor outer sheath stripping device. Background Art

[0002] The power transmission copper wires used in indoor buildings are 2.5 square wires, 4 square wires, 6 square wires and 10 square wires. All four are single-strand hard wires, and the thickness of the copper core increases gradually. Depending on the different electrical equipment, the size of the laid power transmission copper wires is different. Many users who renovate indoors (such as renovating old houses and decorating rough houses) will replace all the original circuits. When the replaced power transmission wires are taken away for recycling, the rubber coating on their surface needs to be peeled off.

[0003] The commonly used outer covering stripping equipment now directly cuts one or more cuts on the surface of the transmission wire, and then peels it off manually. Although the rubber cortex on the surface of the transmission wire has been cut by the cutter, the rubber cortex on its surface is still stuck to the copper wire core, and it is still necessary to manually peel the rubber cortex from the surface of the copper wire core. Therefore, it is impossible to directly separate the rubber cortex on the surface of the transmission wire from the copper wire core. Summary of the Invention

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figures 1-8The diagram shows a device for stripping the outer sheath of a power transmission copper conductor, comprising: a device housing 1 and a circular sleeve 3 fixed inside the device housing 1; a rotating ring 4 is rotatably provided on the inner wall of the circular sleeve 3; a toggle rod 6 is fixedly provided on the outer wall of the toggle rod 4; and a slot for sliding the toggle rod 6 is provided on the outer surface of the circular sleeve 3. The toggle rod 6 can rotate the rotating ring 4 inside the circular sleeve 3 with the rotating ring 4; a plurality of sliding rods 7 are slidably inserted inside the circular sleeve 3; the sliding rods 7 coincide with the axis of the circular sleeve 3, and the sliding direction of the sliding rods 7 is toward the axis of the circular sleeve 3. The inner wall of the rotating ring 4 is fixed with an oblique arc push block 5 with the same number as the sliding rod 7. The sliding rod 7 on the same side is fixed with a dome column 37 at one end close to the oblique arc push block 5, and the dome top of the dome column 37 slides in contact with the oblique arc push block 5. When the rotating ring 4 rotates with the oblique arc push block 5, the dome top of the dome column 37 can push the sliding rod 7 to move toward the axis of the annular sleeve 3. A straightening component that clamps the electrical wire is provided between the plurality of sliding rods 7, and a reset component is provided between the sliding rod 7 and the annular sleeve 3.

[0032] It also includes: a conveying and cutting unit, which is used to cut the rubber layer during the process of clamping and conveying the electrical wire. The conveying and slicing unit is arranged inside the device shell 1. The straightening component presses the electrical wire straight and then the wire is conveyed and cut by the cutting unit for peeling, so that the copper wire core is separated from the rubber layer.

[0033] There are four slide bars 7, two of which are symmetrically distributed up and down, and the other two slide bars 7 are distributed on the left and right sides of a slide bar 7 located above, and the angle between these two slide bars 7 and the slide bar 7 located above is an acute angle, that is, the number of slide bars 7 located in the upper part is three, and the number of slide bar 7 located in the lower part is one. The straightening component includes a push rod 8 fixed to one end of each slide bar 7 close to the axis of the annular sleeve 3, the push rod 8 located in the upper part is rotatably equipped with a correction gear 9 at one end close to the axis of the annular sleeve 3, and the push rod 8 located in the lower part is fixed at one end close to the axis of the annular sleeve 3. An arc support plate 10 is provided, and the distance between the correction gear 9 and the arc support plate 10 and the axis of the annular sleeve 3 is consistent. A center hole is opened in the center of the annular sleeve 3, and the arc support plate 10 passes through the center hole. When the three correction gears 9 and the arc support plate 10 move synchronously toward the center of the annular sleeve 3, the arc support plate 10 can play a bearing role on the electric wire, and under the synchronous squeezing of the three correction gears 9 on the electric wire, the electric wire can be corrected and straightened. The upper end face of the arc support plate 10 is an arc surface, which plays a wrapping role on the electric wire, thereby improving the straightening effect of the correction gear 9 on the electric wire.

[0034] The reset component includes several straight grooves opened in the circular sleeve 3. The number of straight grooves is consistent with the number of slide rods 7, and each circular sleeve 3 is correspondingly distributed on the outside of each slide rod 7. The extension line of the straight groove intersects the axis of the circular sleeve 3 perpendicularly. A first spring 11 is placed inside each straight groove, and the two ends of the first spring 11 are respectively fixed to the slide rod 7 and the straight groove. When the slide rod 7 is pushed, the first spring 11 will be compressed, allowing the first spring 11 to generate a reaction elastic force, thereby facilitating the slide rod 7 to reset following the rotation of the oblique arc push block 5.

[0035] The skin-cutting conveying unit includes two upper and lower limit plates 12 located inside the device housing 1. The two limit plates 12 are respectively fixed to the ends of two downwardly distributed slide bars 7. An optical axis 14 is fixedly provided at one end of the two limit plates 12 close to each other, and a movable frame 13 is slidably assembled on the outer surface of the optical axis 14. The movable frame 13 can only slide up and down and cannot rotate. A second spring 15 is fixedly provided between the movable frame 13 and the limit plate 12 on the same side, and the second spring 15 is distributed on the outside of the optical axis 14. When the two upper and lower slide bars 7 move toward each other with the limit plates 12, the two movable frames 13 are brought closer.

[0036] The movable frame 13 includes a cover plate 13a, a first presser foot plate 13b and a second presser foot plate 13c. The cover plate 13a is fixedly assembled with the slide rod 7. The first presser foot plate 13b and the second presser foot plate 13c extend toward the axis of the circular sleeve 3, and the first presser foot plate 13b and the second presser foot plate 13c are respectively provided with a conveying component and a cutting component on one end surface away from the cover plate 13a. The first presser foot plate 13b is located between the cover plate 13a and the circular sleeve 3. When the two movable frames 13 approach each other, the electric wire can be conveyed by clamping it up and down through the two conveying components, and the cutting component can also be clamped on the surface of the electric wire. During the movement of the electric wire, the rubber cortex is cut by the cutting component.

[0037] The conveying component includes a first rotating shaft 17 rotatably assembled on one end of each first presser foot plate 13b away from the cover plate 13a, and the outer surface of the first rotating shaft 17 is fixedly sleeved with an extrusion feeding gear 18, one end of the first rotating shaft 17 is fixedly sleeved with a worm gear 19, and the external transmission of the worm gear 19 is assembled with a worm sleeve 21, and the inside of the worm sleeve 21 is fixedly provided with a transmission rod 20, and the transmission rod 20 is rotatably assembled on the outside of the first presser foot plate 13b, and the end of the transmission rod 20 away from the worm sleeve 21 rotates and penetrates the limit plate 12, and the external fixed frame of the limit plate 12 is equipped with a reduction motor 16, and a transmission assembly is provided between the output end of the reduction motor 16 and the outer surface of the transmission rod 20, and the limit plate 12 A limit frame sleeve is provided between the reducer motor 16, and two synchronous gears are provided for the internal rotation of the limit frame sleeve. The limit frame is fixed to the limit plate 12, and the output end of the reducer motor 16 and the transmission rod 20 both slide through the limit frame, one of the synchronous gears is fixedly sleeved on the output end of the reducer motor 16, and the other synchronous gear is axially slidably sleeved on the outside of the transmission rod 20, and a synchronous toothed belt is provided for transmission between the two synchronous gears, and the synchronous toothed belt is also located inside the limit sleeve. After the two extrusion feeding gears 18 clamp the electric wire, the transmission rod 20 is driven by the reducer motor 16 to make the worm sleeve 21 rotate with the worm wheel 19, so that the two extrusion feeding gears 18 can be rotated to transfer the electric wire.

[0038] The slitting component includes a rotating column rotatably assembled on one end face of each second pressure foot plate 13c away from the cover plate 13a, and the outer surface of the rotating column is fixedly sleeved with a cutting wheel 22, and the opposite end faces of the two second pressure foot plates 13c distributed up and down are fixedly provided with a stop block 13d, the spacing between the two stop blocks 13d distributed up and down is a, the spacing between the two cutting wheels 22 distributed up and down is b, and the spacing between the two extrusion feeding gears 18 distributed up and down is c, and a<b<c, that is, when the two first rotating shafts 17 clamp the electric wire and move toward the direction of the two cutting wheels 22, the blades of the two cutting wheels 22 will be embedded in the electric wire, and while the blades cut the rubber cortex, they can also embed 1-3mm into the surface of the copper wire core, thereby ensuring that the rubber cortex is effectively cut.

[0039] Example 2: Please refer to Figure 7This embodiment is a further explanation of the first embodiment. A separation component is further provided on the outside of the first rotating shaft 17. The separation component is used to separate the cut rubber cortex from the copper wire core. The separation component includes a sleeve 23 rotatably sleeved on both ends of each first rotating shaft 17. The two sleeves 23 on the same side are away from the end of the first rotating shaft 17 and are provided with a second rotating shaft 24 for common rotation. A different-direction threaded sleeve 25 is fixedly sleeved on the outer surface of the second rotating shaft 24. A second gear 27 and a first gear 26 are fixedly sleeved between the two ends of the first rotating shaft 17 and the two ends of the sleeve 23, respectively. A toothed belt 28 is installed between the first gear 26 and the second gear 27 on the same side. The first gear 26, the second gear 27 and the toothed belt 28 are all located on the inner side of the sleeve 23. Each sleeve A third spring 29 is fixedly arranged between the end 23 away from the axis of the annular sleeve 3 and the second pressure foot plate 13c. The outer diameter of the second gear 27 is larger than the outer diameter of the first gear 26. The counter-threaded sleeve 25 is located on the side of the cutting wheel 22 away from the extrusion feeding gear 18. Under the elastic pressure of the third spring 29, the two counter-threaded sleeves 25 distributed up and down will clamp the slit electrical wires, and as the first rotating shaft 17 rotates with the second rotating shaft 24, the two counter-threaded sleeves 25 can rotate at the same time, and the rotation speed is faster. Through the two synchronously reversed thread grooves on the surface of the counter-threaded sleeve 25, an outward pulling force can be applied to the cutting edge of the rubber cortex of the electrical wire during the rotation process, thereby causing the slit rubber cortex to separate from the copper wire core.

[0040] Example 3: Please refer to Figure 2 、 Figure 3 、 Figure 9 and Figure 10 This embodiment is a further explanation of the first embodiment. A recycling unit is further provided inside the device housing 1. The recycling unit can automatically cut the peeled long banana peel into small segments for recycling. The recycling unit includes a discharge hole 30 opened on the end face of the device housing 1 away from the annular sleeve 3. The discharge hole 30 is used for the copper wire core to pass through. Two limiting sleeves 31 are fixedly distributed on both sides of the discharge hole 30, and the limiting sleeves 31 are distributed inside the device housing 1. The outer surface of each discharge hole 30 is fixedly provided with a hollow spiral tube 32. The hollow spiral tube 32 is fixedly provided on the outer surface of the device housing 1. The upper and lower ends of the tube 32 are both fitted with the inner wall of the device shell 1, and the upper end of the oblique mouth 33 faces the discharge hole 30. A cutting component is provided between the lower end of the hollow spiral tube 32 and the device shell 1. The cutting component cuts off the rubber cortex extending from the lower end of the hollow spiral tube 32. When the cut electrical conductor moves toward the discharge hole 30, the staff can manually pass the copper wire core through the discharge hole 30, and the rubber cortex on both sides is stuffed into the inside of the two oblique mouths 33 to avoid the rubber cortex and the copper wire core from passing out at the same time, affecting the collection of the copper wire core.

[0041] The cutting component includes a bevel portion 33 and a blade docking portion 34 fixedly assembled at the upper and lower ends of each hollow spiral tube 32, and a fixed handle 35 is provided at one end of each blade docking portion 34 away from the hollow spiral tube 32. Both ends of the fixed handle 35 are fixedly provided with an arc cutter 36, and the outer end face of the arc cutter 36 and the end of the blade docking portion 34 are both arc surfaces. The incision of the arc cutter 36 is tangent to the end face of the blade docking portion 34. A connecting shaft is fixedly provided at the center position of each fixed handle 35, and the two connecting shafts are synchronously rotated in opposite directions. As the rubber cortex continues to extend into the interior of the hollow spiral tube 32, it will eventually extend out from the end of the blade docking portion 34. The fixed handle 35 and the arc cutter 36 continue to rotate, which can cut the long strip of rubber cortex into small segments.

[0042] An inclined plate 2 is fixedly installed inside the device shell 1. The side wall of the device shell 1 is also equipped with an openable and closable cabinet door 38, and the cabinet door 38 is located above the downward inclined end of the inclined plate 2. The inclined inclined plate 2 has a gathering effect on the small segments of rubber skin, making it easy to collect and discharge.

[0043] Working principle: a cylinder push rod or an electric push rod can be set up on the outer wall of the annular sleeve 3, and the two ends of the cylinder push rod or the electric push rod are hinged to the outer wall of the annular sleeve 3 and the end of the dial rod 6 respectively. At this time, the staff first straightens the end of the electric wire that needs to be stripped, and places it on the top of the arc support plate 10, and at the same time makes the end of the electric wire be located between the two extrusion feeding gears 18. At this time, the cylinder push rod or the electric push rod is controlled to extend to push the dial rod 6. During the rotation of the rotating ring 4 inside the annular sleeve 3, the dial rod 6 can push the dome column 37 through the oblique arc push block 5, so that the four slide rods 7 carry the push rod 8 to move synchronously toward the center of the annular sleeve 3 until the three correction gears 9 and the arc support plate 10 tightly clamp the electric wire, and the two extrusion feeding gears 18 also clamp the electric wire at the same time. At this time, the operation of the cylinder push rod or the electric push rod is stopped to maintain the state of the rotating ring 4;

[0044] The operator starts the reduction motor 16, and when the reduction motor 16 drives the transmission rod 20 and the worm sleeve 21 to rotate, the first rotating shaft 17 can rotate with the extrusion feeding gear 18 through the transmission assembly of the worm sleeve 21 and the worm wheel 19. At this time, the two extrusion feeding gears 18 can clamp the electrical wires and move them into the interior of the device housing 1. The three straightening gears 9 can straighten the electrical wires during the rolling process, and also ensure that the electrical wires are always clamped in the middle position of the two extrusion feeding gears 18.

[0045] When the electric wire moves toward the discharge hole 30 under the action of the extrusion feeding gear 18, the end of the electric wire will first contact two downwardly distributed cutting wheels 22. The two cutting wheels 22 will cut the electric wire, so that a cylindrical rubber cortex is divided into two semi-cylindrical shapes. The cut part of the electric wire will then contact two downwardly distributed oppositely threaded sleeves 25. As the first rotating shaft 17 rotates, the first gear 26, the second gear 27 and the toothed belt 28 will cause the two oppositely threaded sleeves 25 to rotate synchronously in opposite directions faster. However, the electrical wire is clamped by the two extrusion feeding gears 18, so the two different-direction threaded sleeves 25 slip when rotating on the surface of the electrical wire. Because the incisions of the electrical wire are located at the upper and lower parts, which are also at the center of the two different-direction threaded sleeves 25, the two different-direction threaded sleeves 25 can exert a separation force on the rubber cortex of the electrical wire through the action of the two different-direction thread grooves on their surfaces during the rotation process, that is, exert a force expanding outward from the incision, so that the cut rubber cortex part is separated from the copper wire core in the middle, thereby making it convenient for the staff to directly remove the copper wire core.

[0046] In this solution, when the separated copper wire core slowly moves toward the discharge hole 30, the staff can tear off the rubber cortex on both sides of the copper wire core a little more in advance, and manually guide the copper wire core through the discharge hole 30, and the rubber cortex on both sides enters the interior of the two oblique parts 33 until it extends out from the blade docking part 34. At this time, there is no need to guide the rubber cortex. The two fixed handles 35 can be directly driven by an external motor to rotate synchronously and rapidly in opposite directions with the arc cutter 36. Through the cooperation of the arc cutter 36 and the blade docking part 34, the long rubber cortex can be cut into small segments. The small segments of rubber cortex are more convenient for later collection and processing. Because the long rubber cortex can extend and extend at will and occupies a larger area, in this solution, the copper wire core can be stripped while the rubber cortex can be cut, which is more suitable for the stripping and recycling of long-sized discarded transmission lines.
