Description

Technical Field

[0001] The invention belongs to the technical field of cable insulation cutting, and in particular relates to a cable insulation cutting device for cable stripping. Background Art

[0002] Cables are typically made up of several or several groups of conductors (at least two in each group) twisted together like ropes. Each group of conductors in a cable is insulated from each other, and the entire cable is covered with a highly insulating coating. Cables are characterized by internal conduction and external insulation.

[0003] Existing cable insulation cutting devices usually tighten and fix the cable first, then use a cutting tool to cut into the cable insulation, and as the tool continues to move, the cable insulation is stripped.

[0004] However, during the cable insulation stripping process, the gap between the cable core and the insulation is generally very small, and some cables contain multiple cores wrapped inside the insulation. This makes it easy for the cutter to damage the core during the insulation stripping process, thus affecting the subsequent use of the cable core. Furthermore, the multiple cores adhere to the insulation, making it more difficult to separate the insulation from the multiple cores. Summary of the Invention

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The driving assembly drives all the threaded sleeves to rotate. Since the threaded push rods are slidably connected to the side wall of the No. 1 fixed sleeve, each threaded sleeve simultaneously pushes the threaded push rods to move at a constant speed toward the inside of the No. 1 fixed sleeve through the thread transmission until the tool cuts into a certain depth inside the cable insulation. At this time, the driving assembly is controlled to stop the action to avoid completely breaking the cable insulation and damaging the multiple inner cores inside.

[0029] 2. After the cutter cuts into the cable insulation, the cutter drives the oil delivery assembly to be inserted into the opening of the cable insulation. At this time, under the guidance of the oil pipe and the annular sleeve, the oil pump is started to drip the lubricating oil in the oil tank into the various openings of the cable insulation, avoiding excessive friction between the cable insulation and the subsequent expansion mechanism, vibration mechanism and separation mechanism, which causes the cable to stretch and bend, thereby affecting the guiding accuracy during the cable transportation and cutting process.

[0030] 3. Each electric telescopic sleeve drives the connected angular heating seat to be inserted into the opening of the cable insulation. At this time, the air pump is started to supply air to the No. 2 fixed sleeve. The No. 2 fixed sleeve increases the air pressure in each air bag. Each air bag expands in each cable insulation, thereby disconnecting and separating the opening of the cable insulation. In this process, the angular heating seat is used to heat the outer plastic protective layer of the multiple battery cores from the inside of the cable insulation. At this time, the outer plastic protective layer of the multiple inner cores expands due to the heat. Under the extrusion of the plastic protective layer of the multiple inner cores, the opening of the cable insulation can be further disconnected and separated. The method of disconnecting and separating the cable insulation by squeezing the cable insulation from the inside can not only make the cable insulation able to be cut open, but also effectively protect the multiple inner cores inside.

[0031] 4. Motor No. 2 rotates the gear ring via gear No. 2, which in turn drives all thrust components to reciprocate and roll around the cable, allowing the cable insulation and the multiple inner cores within to fully separate and spread apart, preventing them from adhering to each other under prolonged compression. The outer plastic protective layer of the cable insulation and the multiple inner cores expands with heat, increasing their elasticity. Under the thrust of the thrust component, this enhances the vibration separation effect of the cable insulation and the multiple inner cores. Finally, the elastic telescopic rod can be inserted into the cable insulation sheet to further separate the cable insulation from the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0043] like Figures 1-8 As shown, a cable insulation cutting device for cable stripping provided by the present invention includes a workbench 1, the upper end surface of the workbench 1 is provided with two winding mechanisms 3, the upper end surface of the workbench 1 is fixedly connected to a support frame 2, one side of one winding mechanism 3 is provided with a limiting sleeve 13, the limiting sleeve 13 is fixedly connected to the support frame 2 via a fourth fixing frame 12, and one side of the limiting sleeve 13 is provided with a cutting mechanism 4, which can cut the cable insulation;

[0044] The cutting mechanism 4 is connected to a lubricating mechanism 5, which can extend into the opening of the cable insulation and apply lubricating oil;

[0045] The lubricating mechanism 5 is provided with an expanding mechanism 6 on the side facing away from the cutting mechanism 4. The expanding mechanism 6 can extend into the opening of the cable insulation to heat it, and the expanding mechanism 6 can squeeze and expand the opening of the cable insulation from the inside.

[0046] A vibration mechanism 8 is provided on the side of the expansion mechanism 6 facing away from the lubrication mechanism 5, and the vibration mechanism 8 can reciprocate and oscillate around the outside of the cable insulation;

[0047] A separation mechanism 7 is provided on the side of the vibration mechanism 8 facing away from the expansion mechanism 6 , and the separation mechanism 7 can be inserted into the cable insulation sheet to separate the cable insulation sheath from the cable wire.

[0048] In this embodiment, the two ends of the cable are respectively wound on the two winding mechanisms 3, and the two winding mechanisms 3 are started to convey the cable in one direction. The limiting sleeve 13 first guides and limits the cable, and then the cutting mechanism 4 can open the cable insulation, thereby cutting the cable insulation to a certain depth while preventing the cutting mechanism 4 and the multiple inner cores inside from being scratched; then the lubricating mechanism 5 on one side of the cutting mechanism 4 can extend into the opening of the cable insulation to apply lubricating oil, so as to avoid excessive friction between the cable insulation and the subsequent expanding mechanism 6, vibrating mechanism 8 and separating mechanism 7, which causes the cable to stretch and bend, thereby affecting the guiding accuracy of the cable during the conveying and cutting process;

[0049] Afterwards, the expansion mechanism 6 can squeeze and expand the opening of the cable insulation, so that the opening of the cable insulation is disconnected and separated; and the expansion mechanism 6 can extend into the opening of the cable insulation to heat it. At this time, since the cable insulation is cut to a certain depth, the expansion mechanism 6 heats the side wall of the opening of the cable insulation while also heating the multiple inner cores inside the insulation. At this time, the outer plastic protective layers of the multiple inner cores expand due to the heat, and under the pressure of the plastic protective layers of the multiple inner cores, the opening of the cable insulation can be further disconnected and separated;

[0050] The vibration mechanism 8 can reciprocately squeeze and oscillate around the outside of the cable insulation, so that the open cable insulation and the multiple inner cores inside are oscillated and separated, avoiding the cable insulation and the multiple inner cores, as well as the multiple inner cores sticking to each other and being difficult to separate; finally, the separation mechanism 7 can be inserted into the cable insulation sheet to further separate the cable insulation and the cable line.

[0051] like Figure 2 As shown, a cable insulation skin cutting device for cable stripping provided by the present invention, the cutting mechanism 4 includes a No. 1 fixing sleeve 41, a threaded sleeve 42, a threaded push rod 43, a cutter 44 and a driving assembly 45;

[0052] The support frame 2 is fixedly connected to the No. 1 fixing sleeve 41 through the No. 1 fixing frame 9. The side wall of the No. 1 fixing sleeve 41 is rotatably connected with several threaded sleeves 42 at equal intervals. The inside of the threaded sleeves 42 is threadedly connected with threaded push rods 43. The threaded push rods 43 all penetrate the side wall of the No. 1 fixing sleeve 41, and the threaded push rods 43 are slidably connected relative to the side wall of the No. 1 fixing sleeve 41. The threaded push rods 43 are fixedly connected with a tool 44 at one end inside the No. 1 fixing sleeve 41. The No. 1 fixing frame 9 is connected to a driving assembly 45 that can drive all the threaded sleeves 42 to rotate simultaneously.

[0053] In this embodiment, the drive assembly 45 is started, and the drive assembly 45 drives all the threaded sleeves 42 to rotate. Since the threaded push rods 43 are slidably connected to the side wall of the first fixed sleeve 41, each threaded sleeve 42 simultaneously pushes the threaded push rods 43 to move at a constant speed toward the inside of the first fixed sleeve 41 through the thread transmission until the cutter 44 cuts into the cable insulation to a certain depth. At this time, the drive assembly 45 is controlled to stop the action to prevent the cable insulation from being completely broken and damaging the multiple inner cores therein.

[0054] Driven by the drive assembly 45 , all the cutters 44 can cut into the cable insulation at the same speed at the same time, and the depth of the cutters 44 cutting into the cable insulation can be accurately controlled through the threaded transmission between each threaded sleeve 42 and the threaded push rod 43 .

[0055] like Figure 2 As shown, a cable insulation cutting device for cable stripping provided by the present invention, the driving assembly 45 includes a No. 1 motor 451, a No. 1 gear 452, a transmission gear sleeve 453 and a bevel gear 454;

[0056] The No. 1 motor 451 is fixedly connected to the No. 1 fixing frame 9, and the No. 1 motor 451 is fixedly connected to the No. 1 gear 452. The outer wall of the No. 1 fixing sleeve 41 is rotatably connected to the transmission gear sleeve 453, and the No. 1 gear 452 is engaged with the transmission gear sleeve 453. Each threaded sleeve 42 is fixedly connected to a bevel gear 454, and all bevel gears 454 are engaged with the transmission gear sleeve 453.

[0057] In this embodiment, the No. 1 motor 451 is started, and the No. 1 motor 451 drives the transmission gear sleeve 453 to rotate around the No. 1 fixed sleeve 41 through the No. 1 gear 452. Through the engagement of the transmission gear sleeve 453 with each bevel gear 454, all the threaded sleeves 42 rotate on the No. 1 fixed sleeve 41 at the same time.

[0058] like Figure 3 As shown, a cable insulation cutting device for cable stripping provided by the present invention, the lubricating mechanism 5 includes an oil tank 51, an annular sleeve 52, an oil delivery component 53, an oil pump 54 and an oil pipe 55;

[0059] The No. 1 fixing frame 9 is fixedly connected to the oil tank 51, one end of the No. 1 fixing sleeve 41 is fixedly connected to the annular sleeve 52, an oil pipe 55 is connected between the oil tank 51 and the annular sleeve 52, an oil pump 54 is provided between the oil tank 51 and the oil pipe 55, and a hydraulic valve for unidirectional conduction to the annular sleeve 52 is provided on the oil pipe 55, one end of each of the tools 44 is fixedly connected to an oil delivery component 53, and all oil delivery components 53 are connected to the annular sleeve 52.

[0060] In this embodiment, after the cutter 44 cuts into the cable insulation, the cutter 44 drives the oil delivery assembly 53 to be inserted into the opening of the cable insulation. At this time, under the guidance of the oil pipe 55 and the annular sleeve 52, the oil pump 54 is started to drip the lubricating oil in the oil tank 51 into the various openings of the cable insulation.

[0061] like Figure 4 As shown, a cable insulation cutting device for cable stripping provided by the present invention, the oil delivery component 53 includes a connecting plate 531, a sliding sleeve 532 and a gun head 533;

[0062] One end of the cutter 44 is fixedly connected to a connecting plate 531 , and the connecting plate 531 is fixedly connected to a sliding sleeve 532 . The telescopic end of the sliding sleeve 532 is connected to the annular sleeve 52 , and the other end of the sliding sleeve 532 is elastically connected to a gun head 533 .

[0063] In this embodiment, the cutter 44 drives the gun head 533 to be inserted into the opening of the cable insulation sheath through the connecting plate 531 , and at this time, the sliding sleeve 532 can always maintain communication with the annular sleeve 52 .

[0064] Figure 5 As shown, a cable insulation cutting device for cable stripping provided by the present invention, the expansion mechanism 6 includes a second fixing sleeve 61, an electric telescopic sleeve 62, an angular heating seat 63, an air bag 64 and an air pump 65;

[0065] The No. 2 fixing sleeve 61 is fixedly connected to the support frame 2 through the No. 2 fixing frame 10. A plurality of electric telescopic sleeves 62 are fixedly connected to the inner wall of the No. 2 fixing sleeve 61. The telescopic end of the electric telescopic sleeve 62 is fixedly connected to an angular heating seat 63. The angular heating seat 63 has a port at the conical end facing the center of the No. 2 fixing sleeve 61. An airbag 64 is provided in the angular heating seat 63. The airbag 64 is connected to the inner cavity of the No. 2 fixing sleeve 61 through the electric telescopic sleeve 62. The No. 2 fixing frame 10 is fixedly connected to an air pump 65. The air pump 65 is connected to the inner cavity of the No. 2 fixing sleeve 61 through a pipeline.

[0066] In this embodiment, each electric telescopic sleeve 62 is activated to extend, and each electric telescopic sleeve 62 drives the connected angular heating seat 63 to be inserted into the opening of the cable insulation. At this time, the air pump 65 is activated to supply air to the second fixed sleeve 61, and the second fixed sleeve 61 increases the air pressure in each air bag 64. Each air bag 64 expands in each cable insulation, thereby disconnecting the opening of the cable insulation.

[0067] During this process, the angular heating seat 63 heats the outer plastic protective layer of multiple battery cores from the inside of the cable insulation. At this time, the outer plastic protective layer of the multiple inner cores expands due to the heat. Under the extrusion of the multiple inner core plastic protective layers, the opening of the cable insulation can be further disconnected and separated.

[0068] During the movement of the cable, the lubricating oil in the opening of the cable insulation can prevent the angular heating seat 63 from generating a large friction with the cable insulation; on the one hand, the friction between the angular heating seat 63 and the cable insulation will affect the guiding accuracy during the cable transportation and cutting process, and the friction between the angular heating seat 63 and the cable insulation will generate a large amount of heat, thereby creating a safety hazard; on the other hand, the lubricating oil inside the cable insulation can prevent the airbag 64 from being heated and sticking to the inside of the cable insulation.

[0069] Figure 6 As shown, a cable insulation cutting device for cable stripping provided by the present invention, the vibration mechanism 8 includes a No. 4 fixing sleeve 81, a gear ring 82, a No. 2 motor 83, a No. 2 gear 84 and a thrust assembly 85;

[0070] The No. 4 fixing sleeve 81 is fixedly connected to the support frame 2 through the No. 5 fixing frame 14. The No. 4 fixing sleeve 81 is rotatably connected to the gear ring 82. The No. 5 fixing frame 14 is fixedly connected to the No. 2 motor 83. The output shaft of the No. 2 motor 83 is fixedly connected to the No. 2 gear 84. The No. 2 gear 84 is meshed with the gear ring 82. The inner wall of the gear ring 82 is fixedly connected to multiple thrust assemblies 85 at equal intervals.

[0071] During this process, the No. 2 motor 83 is started, the No. 2 motor 83 drives the No. 2 gear 84 to rotate, the No. 2 gear 84 drives the gear ring 82 to rotate, and the gear ring 82 drives all the thrust components 85 to rotate and roll back and forth around the cable, so that the cable insulation and the multiple inner cores inside can be fully spread out and separated, and under the lubrication of the lubricating oil, the cable insulation and the multiple inner cores inside can be further prevented from sticking to each other under long-term extrusion pressure.

[0072] Figure 7 As shown, a cable insulation cutting device for cable stripping provided by the present invention, the thrust assembly 85 includes an electric telescopic seat 851, a rotating frame 852 and a roller 853;

[0073] The electric telescopic seats 851 are fixedly connected to the inner wall of the gear ring 82 . The telescopic ends of the electric telescopic seats 851 are fixedly connected to the rotating frame 852 , and the rotating frame 852 is rotatably connected to the roller 853 .

[0074] In this embodiment, the electric telescopic seat 851 can drive the roller 853 to elastically abut the cable line through the rotating frame 852. When the gear ring 82 rotates, the gear ring 82 drives all the rollers 853 to roll along the outside of the cable insulation. Since the cable insulation is divided into multiple strips, under the rolling pressure of the roller 853, the cable insulation and the multiple inner cores can squeeze and vibrate each other. At the same time, since the cable insulation and the multiple inner cores are coated with lubricating oil, the extrusion friction between the roller 853 and the cable insulation is too large, which can avoid excessive twisting of the cable insulation.

[0075] Figure 8 As shown, a cable insulation cutting device for cable stripping provided by the present invention, the separation mechanism 7 includes a No. 3 fixing sleeve 71, an elastic telescopic rod 72 and a ball 73;

[0076] The third fixing sleeve 71 is fixedly connected to the support frame 2 through the third fixing frame 11 . A plurality of elastic telescopic rods 72 are fixedly connected inside the third fixing sleeve 71 . The telescopic ends of the elastic telescopic rods 72 are universally connected to balls 73 .

[0077] In this embodiment, when the cable passes through the No. 3 fixing sleeve 71, each elastic telescopic rod 72 can be inserted into the cable insulation, thereby further dividing the cable insulation and further dispersing the multiple inner cores inside the cable insulation.

[0078] Working principle:

[0079] Wind the two ends of the cable on the two winding mechanisms 3 respectively, start the two winding mechanisms 3 to convey the cable in one direction, and the limiting sleeve 13 first guides and limits the cable;

[0080] Start the drive assembly 45, which drives all the threaded sleeves 42 to rotate. Since the threaded push rods 43 are slidably connected to the side wall of the No. 1 fixed sleeve 41, each threaded sleeve 42 simultaneously pushes the threaded push rods 43 to move at a constant speed toward the inside of the No. 1 fixed sleeve 41 through thread transmission until the tool 44 cuts into a certain depth inside the cable insulation. At this time, the drive assembly 45 is controlled to stop moving to avoid completely breaking the cable insulation and damaging the multiple inner cores inside.

[0081] After the cutter 44 cuts into the cable insulation, the cutter 44 drives the oil delivery assembly 53 to be inserted into the opening of the cable insulation. At this time, under the guidance of the oil pipe 55 and the annular sleeve 52, the oil pump 54 is started to drip the lubricating oil in the oil tank 51 into the various openings of the cable insulation, avoiding excessive friction between the cable insulation and the subsequent expanding mechanism 6, vibrating mechanism 8 and separating mechanism 7, which causes the cable to stretch and bend, thereby affecting the guiding accuracy of the cable during the transportation and cutting process.

[0082] Each electric telescopic sleeve 62 is activated to extend, and each electric telescopic sleeve 62 drives the connected angular heating seat 63 to be inserted into the opening of the cable insulation. At this time, the air pump 65 is activated to supply air to the second fixed sleeve 61. The second fixed sleeve 61 increases the air pressure in each air bag 64. Each air bag 64 expands in each cable insulation, thereby disconnecting the opening of the cable insulation.

[0083] During this process, the angular heating seat 63 heats the outer plastic protective layer of the multiple cores from the inside of the cable insulation. At this time, the outer plastic protective layer of the multiple inner cores expands due to the heat. Under the pressure of the multiple inner core plastic protective layers, the opening of the cable insulation can be further disconnected and separated.

[0084] By squeezing the cable insulation from the inside to separate the cable insulation, not only can the cable insulation be cut open, but the multiple inner cores therein can also be effectively protected.

[0085] Motor 83 is activated, driving gear 84, which in turn drives gear ring 82. Gear ring 82 then drives thrust assemblies 85 to reciprocate and roll around the cable, allowing the cable insulation and the multiple inner cores to fully separate and spread apart, preventing them from adhering to each other under prolonged compression. The plastic protective layer of the cable insulation and the multiple inner cores expands and becomes more elastic due to heat, which, under the thrust of thrust assembly 85, enhances the vibration separation effect of the cable insulation and the multiple inner cores. Finally, the elastic telescopic rod 72 is inserted into the cable insulation sheet to further separate the cable insulation from the cable.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0087] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
