TECHNICAL FIELD

[0001] The application belongs to the field of optical cable outer wrapping layer stripping processing, and particularly relates to an optical cable stripping device. BACKGROUND

[0002] The optical cable stripping is mainly used in the construction, maintenance and repair scene of the optical cable communication network, such as optical cable fiber splitting, preparation before fusion, installation of optical cable terminal box or joint box and the like.

The problem that the existing strippers are mostly manually operated by workers and the strippers cannot automatically strip the optical cable is overcome.

[0004] However, the existing technology cuts the cable on the load roller by directly pressing the cutter, and since the cable in the conveying process is only clamped and cut by the bottom and very narrow blade, it is difficult to effectively limit the cable in the radial direction, resulting in unstable cutting;

[0005] In addition, the outer wall of the thicker optical cable is also thicker, or the armored optical cable, and the above application scenarios only make a cut, and the outer wrapping layer is still closed. When the optical cable is stripped, the optical cable will be subjected to a large bending and impact, causing damage to the optical fiber. CONTENT OF THE UTILITY MODEL

[0006] TECHNICAL PROBLEM, the technical problem to be solved by the present application is to improve the clamping stability of the portable stripper, and to cut the optical cable outer skin in multiple directions to reduce the stripping difficulty.

[0012] Cutting mechanism includes:

[0013] Two symmetrical horizontal adjusting rods are arranged in the adjusting seat on both sides.

[0014] Connecting piece, arranged at one end of horizontal adjusting rod;

[0015] Cutting knife, arranged on connecting piece.

[0019] Further, the connecting piece includes:

[0020] Hoop, for clamping on connecting end;

[0022] Connecting end surface is perpendicular to hoop;Connecting end surface and connecting end end surface are in contact with each other.

[0023] The double-fork mounting seat is arranged on the connecting end surface and is used for connecting the cutter. The double-fork mounting seat comprises two support rods arranged oppositely upwards and downwards. The support rods can be arranged in a triangular prism shape or in a form that a main body is matched with a reinforcing plate, so as to further improve the stability of the mounting seat and the stability of the cutter.

[0024] Further, first slot holes are arranged on both sides of the frame body, and the slot holes are directed from the position of the driving shaft to the position of the driven shaft.

[0025] The adjusting seat penetrates the first slot hole. The adjusting seat comprises a central threaded connecting hole and an outer contour which is in sliding fit with the side wall of the first slot hole. That is, the two side surfaces of the adjusting seat are parallel to and in contact with the side wall of the first slot hole in sliding fit, so as to enable the adjusting seat to move up and down for adjustment, so as to adapt to optical cables of different diameters and enable the cutter to be close to the center lines on both sides of the optical cables for cutting.

[0026] The adjusting seat extends to the outer wall of the outer part of the frame body and is provided with a fastening mechanism. A threaded line can be arranged on the outside, and a fastening nut is used as a fastener to fasten the position after adjustment, so as to prevent the cutter from moving in the vertical direction during cutting.

That is, the driving wheel and the driven wheel are oppositely arranged as a clamping wire feeding device. The rotating shaft of the driving wheel penetrates both sides of the frame body and is connected with the frame body through a bearing. A multi-edge connecting shaft is arranged at the end of the rotating shaft for connecting a driving device.

[0028] Further, the driven wheel is connected through an adjustable movable frame. The movable frame comprises a door-shaped main body, and connecting holes are arranged on both sides of the movable frame for connecting fixed shafts. The driven wheel is arranged at the middle part of the fixed shafts.

[0029] The driven wheel and the fixed shaft are connected through a bearing, or the fixed shaft and the connecting hole are connected through a bearing.

[0030] Limiting seats are further arranged on both sides of the movable frame, and second slot holes are arranged on the frame body and directed to the rotating shaft. The limiting seats penetrate the second slot holes. The movable frame can move up and down to meet the clamping of cables of different diameters.

[0031] The top of the movable frame is connected with the frame body through a longitudinal adjusting rod. The longitudinal adjusting rod is at least provided with threads in the middle and upper part. The longitudinal adjusting rod penetrates the upper wall of the frame body and is provided with a threaded connecting seat at the penetrating position. The threaded connecting seat is in threaded fit with the longitudinal adjusting rod.

[0032] The movable frame is horizontally limited through the limiting seats on both sides and the longitudinal adjusting rod. The height of the movable frame can be adjusted only by rotating the longitudinal adjusting rod to adapt to different clamping requirements.

[0033] Further, a buffer hole is formed on the top of the movable frame, the inner diameter of the buffer hole is larger than the outer diameter of the longitudinal adjusting rod, the longitudinal adjusting rod passes through the buffer hole, and a top cap is arranged at one end of the inner side of the movable frame, the outer diameter of the top cap is larger than the inner diameter of the buffer hole;

[0034] The elastic positioning nut is arranged between the upper frame and the movable frame on the longitudinal adjusting rod, and the buffer spring is arranged between the elastic positioning nut and the outer wall of the movable frame. The movable frame has a buffer zone for up and down movement, and has a better protection effect on the cable relative to the fixed clamping.

[0035] Further, the cutter is a circular cutter. The cable is rolled and cut, and the line driving load of the driving wheel is reduced.

[0036] The beneficial effects of the present application are: the line feeding mechanism adopts the opposite clamping mode of the driving wheel and the driven wheel, so that the optical cable remains stable during stripping, avoids sliding or displacement, and ensures smooth operation. The cutting mechanism is equipped with at least two circular cutters in different positions, which can perform multi-directional rolling cutting on the outer skin of the optical cable to form multiple cuts, so that the outer skin is more easily separated from the inner core, greatly reducing the difficulty of separation and improving work efficiency. In addition, through the design of the transverse adjusting rod and the adjusting seat, the horizontal cutting depth and vertical position of the cutter can be flexibly adjusted to adapt to optical cables of different diameters and skin thicknesses, showing universality and adaptability. The cutter and the transverse adjusting rod are designed separately because the transverse adjusting rod needs to adjust the transverse depth by rotating, and the cutter needs to always remain horizontal. During use, the user can first loosen the relative connection between the clamp and the clamp to make it rotatable, and then tighten the clamp and the clamp after adjusting the transverse adjusting rod to the specified position. Another beneficial effect of the split design is that it is convenient to disassemble and replace the cutter. At the same time, the buffer hole and the buffer spring arranged above the driven wheel provide elastic protection during clamping to avoid damage to the optical cable due to excessive extrusion and ensure its integrity. In operation, the user only needs to rotate the horizontal adjusting knob or the longitudinal adjusting rod to easily adjust the position of the cutter and the clamping device, simplifying the process and improving the stripping efficiency. The rolling cutting design of the circular cutter also reduces the line driving resistance of the driving wheel, effectively reducing the driving load. BRIEF DESCRIPTION OF DRAWINGS
