It discloses a cable stripping device, which strips the cable by means of a plurality of knives that can be moved synchronously for adjustment. However, in the actual process of cable stripping, it is not only necessary to move the knives along the axial direction of the cable to strip the cable sheath, but also necessary to move the knives along the circumferential direction of the cable to cut the cable sheath. In some cases, after cutting the cable sheath, it is also necessary to pry the cable sheath off in order to completely peel the cable sheath off the cable to complete the stripping operation. It is cumbersome to perform these multiple operations manually in sequence or on different devices separately.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0040] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] A cable stripping device, such as Figure 1-Figure 3 As shown, it includes a base 11, and two front and rear opposite support plates 12 are connected to the upper side of the base 11. A ring-shaped rotating drum 21 rotates between the two support plates 12. A rotating drive group for driving the rotating drum 21 to rotate is provided on the support plate 12. Three axial wire stripping knives 31 are evenly arranged in the circumferential direction are provided on the rotating drum 21. The front side of the axial wire stripping knife 31 has a blade 1, and the blade 1 of the front side of the axial wire stripping knife 31 faces the same axial direction as the rotating drum 21. When the cable to be stripped passes through the rotating drum 21 from front to back, the axial wire stripping knife 31 can strip the cable along the axial direction of the cable. Three circumferential wire stripping knives 41 are evenly arranged in the circumferential direction are provided on the rotating drum 21. The circumferential wire stripping knives 41 are driven by a linear drive group 4 to approach and move away from the center of the rotating drum 21. The linear drive group 4 is installed on the support plate 12, and the blade of the circumferential wire stripping knife 41 is perpendicular to the axial center of the rotating drum 21. The circumferential wire stripping knife 41 is controlled to move toward the center of the cable to cut into the stripped portion of the cable after the axial wire stripping knife 31 strips the cable along the axial direction of the cable. The blade of the circumferential wire stripping knife 41 and the blade of the axial wire stripping knife 31 are located in the same plane, thereby ensuring that the circumferential wire stripping knife 41 can accurately cut into the portion of the cable stripped by the axial wire stripping knife 31. At this time, the rotary drive group is controlled to drive the drum 21 to drive the circumferential wire stripping knife 41 and the axial wire stripping knife 31 to rotate clockwise. The circumferential wire stripping knife 41 will gradually move along the circumference of the cable to cut off the stripped cable skin. At the same time, the axial wire stripping knife 31 will gradually move along the circumference of the cable to pry off the stripped and cut cable skin, thereby conveniently completing the cable stripping operation. The stripping, cutting and prying steps are interrelated and coordinated with each other, and the degree of automation is high.

[0042] like Figure 4 As shown, the rotary drive group includes a driven gear ring 22, which is connected to the rotating drum 21, and is driven to rotate by an electric gear 23, which is mounted on a support plate 12 (in order to simplify the view and highlight the key parts, the positional relationship is not illustrated in the accompanying drawings, but it is easy for a person skilled in the art to understand and implement it after viewing the present invention); when in use, the electric gear 23 is controlled to drive the driven gear ring 22 to rotate the rotating drum 21, so that the rotating drum 21 can drive the circumferential wire stripping knife 41 and the axial wire stripping knife 31 to rotate clockwise.

[0043] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the linear drive group 4 includes an electric screw 42, and the electric screw 42 rotates on the rotating drum 21, and the axial center line of the electric screw 42 is toward the center of the rotating drum 21. In another embodiment, the electric screw 42 can also be changed to a screw that is manually driven to rotate. The electric screw 42 is threadedly connected with a slider 43 that slides on the support plate 12, and the slider 43 is connected to the circumferential wire stripping knife 41 through a slide rod 44; when in use, the electric screw 42 is controlled to drive the slider 43 to approach the center of the rotating drum 21, and the slider 43 will drive the circumferential wire stripping knife 41 to move toward the center of the cable through the slide rod 44 to cut into the stripped part of the cable. Similarly, the electric screw 42 is controlled to drive the slider 43 away from the center of the rotating drum 21, and the circumferential wire stripping knife 41 also moves away from the cable.

[0044] like Figure 6 As shown, the linear drive group 4 also includes a spring 45. The first end of the slide rod 44 is slidably arranged on the slider 43. A spring 45 located inside the slide rod 44 is connected between the first end of the slide rod 44 and the slider 43. The movement of the slider 43 will drive the slide rod 44 to move through the spring 45. The second end of the slide rod 44 is connected to the circumferential wire stripping knife 41. When the slide rod 44 drives the circumferential wire stripping knife 41 to cut into the stripped part of the cable, the spring 45 will deform adaptively. In this way, in the process of the circumferential wire stripping knife 41 rotating and cutting the stripped cable sheath, under the pressure applied by the spring 45, the circumferential wire stripping knife 41 can gradually cut the cable sheath and avoid cutting the cable core with higher hardness.

[0045] like Figure 3 As shown, it also includes a driving component 1, an axial wire stripping knife 31 is rotatably arranged on the rotating drum 21, and the driving component 1 drives the axial wire stripping knife 31 to rotate counterclockwise to adjust the angle of the axial wire stripping knife 31, so that the axial wire stripping knife 31 strips the cable along the axial direction of the cable in an inclined manner. The driving component 1 is arranged on the rotating drum 21, and the axial wire stripping knife 31 has a blade 2, the blade 2 of the axial wire stripping knife 31 is perpendicular to the blade 1 on the axial wire stripping knife 31, and the blade 2 of the axial wire stripping knife 31 is parallel and faces the rotating drum 21. axial center line, when the rotating drum 21 drives the circumferential wire stripping knife 41 and the axial wire stripping knife 31 to rotate clockwise, the inclined axial wire stripping knife 31 can be used to more conveniently pry open the cable skin, and the blade 2 of the axial wire stripping knife 31 will further strip the cable skin from the cable core; in addition, it should be explained that by adjusting the angle of the axial wire stripping knife 31, the distance between the axial wire stripping knife 31 and the center of the rotating drum 21 can also be cleverly adjusted, so that cables of different sizes can be processed to a certain extent.

[0046] like Figure 3 and Figure 7As shown, the drive assembly 1 includes a connecting plate 32, the blade back of the axial wire stripping knife 31 is connected to the connecting plate 32, and a cylinder 33 is provided on the rotating drum 21 through the rotating plate. The telescopic rod of the cylinder 33 is hinged to the end of the connecting plate 32. Initially, the telescopic rod of the cylinder 33 is in an extended state (such as Figure 3 ), when the angle of the axial wire stripping knife 31 needs to be adjusted, the telescopic rod of the control cylinder 33 is retracted, and the cylinder 33 drives the axial wire stripping knife 31 to swing through the connecting plate 32, so as to adjust the angle of the axial wire stripping knife 31, and the degree of automation is high.

[0047] like Figure 3 , Figure 7 and Figure 8 As shown, it also includes a sliding frame 51, on which the sliding frame 51 slides, and the sliding frame 51 is suitable for sliding in the direction close to the center of the rotating drum 21. The axial wire stripping knife 31 is rotatably arranged on the sliding frame 51, and the axial wire stripping knife 31 is rotated on the rotating drum 21 to adjust the angle through the support of the sliding frame 51. The sliding frame 51 is driven to move by the driving component 2, and the driving component 2 is arranged on the rotating drum 21; the driving component 2 is controlled to drive the sliding frame 51 close to the center of the rotating drum 21, and the sliding frame 51 will drive the axial wire stripping knife 31 close to the center of the rotating drum 21. During this process, the axial wire stripping knife 31 will rotate on the sliding frame 51, and the axial wire stripping knife 31 will drive the cylinder 33 to rotate. At this time, the driving component 2 is stopped, and the cylinder 33 is controlled to drive the connecting plate 32 to drive the axial wire stripping knife 31 to rotate, so that the axial wire stripping knife 31 can be realigned.

[0048] like Figure 5 , Figure 7 and Figure 8 As shown, the driving assembly 2 includes a resistance rod 52, one side of the sliding frame 51 is connected to the resistance rod 52, and a rotating frame 53 is rotated on the rotating drum 21. The rotating frame 53 is provided with a waist-shaped groove 54 surrounding the resistance rod 52. One end of the waist-shaped groove 54 of the rotating frame 53 gradually deviates from the center of the rotating frame 53, so that the rotating frame 53 rotates counterclockwise through the waist-shaped groove 54 to squeeze the resistance rod 52 close to the center of the rotating drum 21. The resistance rod 52 will drive the axial wire stripping knife 31 to approach the center of the rotating drum 21 through the sliding frame 51. Similarly, the clockwise rotation of the rotating frame 53 will The axial wire stripping knife 31 is far away from the center of the rotating drum 21, and a driven gear ring 2 55 is connected to the rotating frame 53, and the driven gear ring 2 55 is driven to rotate by the electric gear 2 56, and the electric gear 2 56 is installed on the support plate 12; when in use, the electric gear 2 56 is controlled to drive the driven gear ring 2 55 to drive the rotating frame 53 to rotate, so as to automatically adjust the distance between the axial wire stripping knife 31 and the center of the rotating drum 21, and for the three axial wire stripping knives 31, the three axial wire stripping knives 31 can be synchronously adjusted by opening the same number of waist-shaped grooves 54 on the rotating frame 53, and the synchronization is high.

[0049] like Figure 1 , Fig. 9 , Fig.10 and Fig.11 As shown, it also includes a support plate 13, two support plates 13 opposite to each other are connected to the base 11, a turntable 24 concentric with the drum 21 is rotatable on the support plate 13, and the shape of the turntable 24 is annular. When stripping the cable, the cable passes through the two turntables 24 and the drum 21 in sequence from front to back, and three rotating columns 62 arranged uniformly in the circumferential direction are rotated between the two support plates 13, and the three rotating columns 62 are all connected with guide rods 61, and the three guide rods 61 are arranged uniformly in the circumferential direction in an alternating manner from front to back, and the cable is guided to the center through the triangular space surrounded by the three guide rods 61, and the first end of the guide rod 61 is connected to the rotating column 62, and the second end of the guide rod 61 is slidably provided with a rotating sleeve 63, and the rotating sleeve 63 is rotatably arranged on the turntable 24. In this embodiment, the two rotating sleeves 63 in the front are rotatably arranged in the front The rearmost rotating sleeve 63 is rotatably arranged on the rear rotating disc 24. When the rotating disc 24 is rotated clockwise, the rotating disc 24 will drive the guide rod 61 to swing with the rotating column 62 as the center through the rotating sleeve 63, and the rotating sleeve 63 will slide along the guide rod 61. Therefore, the triangular space surrounded by the three guide rods 61 will gradually shrink with the center of the rotating disc 24. An electric roller 64 is installed between the first end and the second end of the guide rod 61. When the cable passes through the triangular space surrounded by the three guide rods 61, the cable will contact the electric roller 64. Controlling the rotation of the electric roller 64 can smoothly convey the cable backward. After the cable stripping is completed, controlling the electric roller 64 to rotate in the opposite direction can conveniently withdraw the cable. The rotating disc 24 is driven to rotate by the driving component three, and the driving component three is arranged on the support plate 2 13.

[0050] like Fig.10 and Fig.11 As shown, the driving component three includes a driven gear ring three 71, and the two turntables 24 are connected to the driven gear ring three 71. The support plate 13 is equipped with a motor 72. The output shaft of the motor 72 is connected to two front-to-back spur gears 73, and the two front-to-back spur gears 73 are respectively engaged with the two front-to-back driven gear rings three 71. When in use, the motor 72 is controlled to drive the two spur gears 73 to rotate and engage with the driven gear ring three 71.
