Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 to 5, the utility model provides a skirt stripping structure for a cable insulation layer, which comprises a rotating body 1, wherein an anti-slip flange 12 is arranged on an outer wall of the rotating body 1, the anti-slip flange 12 is uniformly distributed along the circumferential direction of the rotating body 1, the anti-slip effect can be achieved when the rotating body 1 is held by a hand, a through hole is formed in the middle of the rotating body 1, a plurality of accommodating grooves 11 are formed in the inner wall of the through hole, 6 accommodating grooves 11 are formed in the embodiment, the 6 accommodating grooves 11 are uniformly distributed along the circumferential direction of the through hole, a roller 2 is rotatably arranged in the accommodating groove 11, the roller 2 is rotatably arranged in the accommodating groove 11 through a pin shaft, part of the roller 2 protrudes out of the accommodating groove 11 and extends into the through hole, a clamping area 3 is formed between the 6 rollers 2, the clamping area 3 is used for clamping a cable 6 (hereinafter referred to as a cable 6) with an inner sheath stripped, when the rotating body 1, the gyro wheel 2 rotates along the outer wall of cable 6, is equipped with two at least separation blades 4 and at least one on one side opening of interlude hole and shells skirt sword 5, and separation blade 4 all extends to the middle part of clamping area 3 with shelling skirt sword 5, as shown in fig. 2~3, shells skirt sword 5 including shelling cutting edge 51 and first connecting portion 52, and shelling cutting edge 51 passes through first connecting portion 52 and connects on the inner wall of interlude hole, and shells and form the arc between cutting edge 51 and the connecting portion and dodge groove 53. It should be noted that the stripping blade 51 is angled with respect to the end wall of the rotating body 1 so that the stripping blade 51 can be inserted into the insulation 62 of the cable 6. The arc-shaped avoiding groove 53 is used as an avoiding groove for the semi-conducting layer 63 when the peeling blade 51 peels off the end wall of the insulating layer 62 of the cable 6, so that the peeling blade 51 can peel off an annular notch on the end wall of the insulating layer 62 of the cable 6, and when the semi-conducting layer 63 is peeled off, the semi-conducting layer 63 can be conveniently peeled off by starting from the annular notch. The skirting structure is applied to the cables 6 on the same line.
As shown in fig. 4, the blocking plate 4 includes a blocking portion 41 and a second connecting portion 42, the blocking portion 41 is connected to the inner wall of the insertion hole through the second connecting portion 42, and a detent 43 is formed between the blocking portion 41 and the second connecting portion 42. After the stripping blade 51 strips the end wall of the insulating layer 62 of the cable 6 into an annular notch, the end wall of the cable 6 is just abutted against the detent 43. The blocking part 41 can avoid the problem that the peeling blade 51 damages the copper core 61 of the cable 6 due to the extrusion deformation of the peeling blade 5 and the end wall of the cable 6 caused by the fact that the peeling blade 51 peels the insulating layer 62 too deeply.
In use, as shown in figure 5, the cable 6 is first passed through the through-penetration such that the cable 6 is located in the clamping zone 3 and the peeling edge 51 of the peeling knife 5 is just abutting against the end wall of the insulation 62 of the cable 6. The rotator 1 is held and rotated, the end wall of the insulating layer 62 of the cable 6 is stripped by the stripping blade 51 of the skirting stripping knife 5 to form an annular notch, and finally the end wall of the cable 6 just abuts against the clamping position 43 without damaging the copper core 61 of the cable 6, so that the semi-conducting layer 63 is stripped at the annular notch at the later stage conveniently.
As shown in fig. 4, the two sides of the blocking portion 41 are provided with the chamfered slopes 411, and the chamfered slopes 411 serve to reduce the friction force between the blocking portion 41 and the end wall of the cable 6, so that the rotating body 1 is relatively labor-saving to rotate.
The two skirt peeling knives 5 are arranged, the four separation blades 4 are arranged, and the separation blades 4 and the skirt peeling knives 5 are evenly distributed along the circumferential direction of the through holes. The four retaining pieces 4 are in mirror symmetry by taking the connecting line of the two skirt peeling knives 5 as a center, the two skirt peeling knives 5 simultaneously peel off the end wall of the insulating layer 62 of the cable 6, the circumferential stress of the whole rotating body 1 is stable, and the rotating body 1 cannot cause the peeling blades 51 of the skirt peeling knives 5 to damage the copper core 61 due to axial deviation.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
