Problems solved by technology

[0004] However, the width of the outer protection tape is greater than the wrapping width of the inner protection tape. When the outer protection tape covers the wrapping gap of the inner protection tape, it is impossible to judge whether the outer protection tape is in the middle of the wrapping gap of the inner protection tape.

Embodiment 1

[0039] Embodiment 1: a kind of cable armoring machine, such as figure 1As shown, it includes a frame 1, a turret 2, a detection device 4, a deviation correction device 5 and a driving structure; the frame 1 includes a base 12, a front support frame 11 and a rear support frame 13, and the front support frame 11 and the rear support frame 13 are respectively The left and right ends of the base 12 are fixedly connected. The two ends of the turret 2 are rotatably connected to the front support frame 11 and the rear support frame 13 respectively, and the cables 3 to be armored pass through the front support frame 11, the turret 2 and the rear support frame 13 successively from the left, and are then wound up on the On the winding device (not shown in the figure), the winding device rotates to move the cable 3 axially, wherein the cable 3 and the turret 2 are arranged coaxially. Two tape reels 21 are rotatably connected to both sides of the turret 2 . The two tape reels 21 are coax...

Embodiment 2

[0045] Embodiment 2: a kind of double-strip material winding process, concrete steps are as follows:

[0046] Step S1: threading the cable 3, putting the cable 3 on the armoring machine, winding one end of the cable 3 on the winding device, and winding the cable 3 when the winding device starts, so as to exert a pulling force on the cable 3, so that The cable 3 slowly passes through the armoring machine.

[0047] Step S2: Fix the inner layer protective tape 22, pass one end of the inner layer protective tape 22 through the guide belt device 24 and the deviation correction device 5 and then fix it to one end of the cable 3, and form an angle between the inner layer protective tape 22 and the cable 3 , so that when the inner layer protection tape 22 is wrapped around the cable 3, the wrapping angle is formed; then the armoring machine is started slowly, so that the inner layer protection tape 22 gap is wrapped around the cable 3; the inner layer protection tape 22 and the cable ...

Embodiment 3

[0055] Embodiment 3: a cable 3 armoring process, the difference from Embodiment 2 lies in step S2, step S4 or step S5.

[0056] The marking lines in step S2 are marking lines drawn on the surface of the inner protective tape 22 with a water-based pen, and the distance between the two marking lines is greater than the wrapping gap of the outer protective tape 23 .

[0057]When observing whether the outer layer protection tape 23 meets the requirements in step S4, when the marking line on the left side is not blocked by the outer layer protection tape 23, it means that the outer layer protection tape 23 is shifted to the left; When the outer protective tape 23 is blocked, it means that the outer protective tape 23 is shifted to the right; The quality of the armored cable 3 is judged, and the step S5 does not need to remove the marking line, which reduces working steps and makes the armoring process simpler and more convenient.

Abstract

The invention discloses a double-strip winding technology, and belongs to the technical field of cable machining, solving the problem that relative positions of an outer-layer protection strip and aninner-layer protection strip is difficult to judge. The key point of the technical scheme comprises the following steps of S1, arranging a cable in a penetrating manner; S2, fixing the inner-layer protection strip; S3, fixing the outer-layer protection strip; S4, pre-winding: starting an armoring machine with slow speed, and observing the winding effect; S5, winding, wherein the winding speed is uniformly improved; and S6, cutting: cutting off the inner-layer protection strip and the outer-layer protection strip after armoring is completed, wherein a marker line is marked on the outer surfaceof the inner-layer protection strip before winding in the step S5. The technology provided by the invention is reasonable in structure, the condition that whether the outer-layer protection strip is positioned in the middle position of the winding gap of the inner-layer protection strip is judged through observing a position relationship between the marker line and the side of the outer-layer protection strip, and the quality of the armored cable is more simply judged.

Description

technical field [0001] The present invention relates to a cable processing technology, more particularly, it relates to a double tape winding technology. Background technique [0002] Armored cables are made of different material conductors packed in metal sleeves with insulating materials and processed into a bendable solid assembly. The cable mechanical protection layer can be added to the cable of any structure to increase the mechanical strength of the cable and improve the corrosion resistance. It is a wire and cable designed for areas that are vulnerable to mechanical damage and corrosion. Generally, an armoring machine is used to coat the cable with a protective layer. [0003] At present, the protective layer of an armored cable includes an inner protective tape and an outer protective tape. The inner protective tape and the outer protective tape are wrapped with a double-layer gap. The gap should be covered by the outer protective tape near the middle. The center...
