Description

Technical Field

[0001] The utility model belongs to the technical field related to optical cable production, and particularly relates to a meter-counting device for an armoring machine incoming line. Background Art

[0002] Armored optical cable is an optical cable with a protective "armor" (stainless steel armor tube) wrapped around the optical fiber core. This stainless steel armor tube can effectively protect the optical fiber core from animal chewing, moisture erosion or other damage.

[0003] Armoring machines (stranding machines) are essential equipment for producing armored tubes. Currently, these machines utilize their own meter counters, which can result in significant meter deviations. For example, two armoring machines of the same model, with identical parameters, can produce armored optical cables with deviations of +30 meters and +50 meters, respectively. Therefore, we propose a new inlet meter counter for armoring machines. This device, located at the inlet of the machine, not only allows for the convergence of optical fibers and reinforcement elements, but also allows for fiber metering, reducing production waste. Summary of the Invention

[0004] The utility model provides an auxiliary meter counting device for an armoring machine, which can realize the merging of optical fibers and reinforcing elements, and the meter counting after the merging.

[0005] The technical solution adopted by this utility model is:

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The utility model discloses an armoring machine inlet metering device, comprising a mounting plate 1, an adjusting frame 2, an encoder 3, a meter wheel 4, a rubber wheel 5, and a junction plate 6. The front side of the mounting plate 1 is provided with an L-shaped vertical plate 7 perpendicular thereto, and the upper portion of the L-shaped vertical plate 7 is vertically provided with two groups of first oblong through holes 9, and the lower portion of the adjusting frame 2 is provided with a first threaded through hole 10. The adjusting frame 2 is arranged on the L-shaped vertical plate 7 by bolts and nuts and can slide up and down along the L-shaped vertical plate 7; by loosening the nuts, the adjusting frame can be moved up and down, and by tightening the nuts, the adjusting frame is fixed, and the position of the adjusting frame is changed so that the clamping surfaces of the meter wheel and the rubber wheel correspond to the junction tube at the feed end of the armoring machine.

[0019] The encoder 3 is arranged on the adjustment frame 2, and its rotating shaft extends out of the adjustment frame 2. The meter wheel 4 is arranged on the encoder's rotating shaft. The meter wheel is connected to the movement of the object to be measured and records the object's movement distance. The encoder is used to convert the movement of the meter wheel into an electrical signal and send it to the controller for measurement and control. The rubber wheel 5 is rotatably arranged at the small end of the convex fixed shaft 8 through a bearing. The rubber wheel 5 is located directly above the meter wheel and can move up and down to approach or move away from the meter wheel. The rubber wheel is close to the meter wheel and is in close contact with it to achieve the transportation of optical fiber and reinforcement elements. A bracket is arranged on the adjustment frame 2. The line junction plate 6 is arranged on the front side of the meter wheel 4 through the bracket. The line junction plate 6 is provided with a line junction through hole 21.

[0020] In use, the device is mounted on a mounting plate at the feed end of the armoring machine, with the clamping surfaces of the meter wheel and rubber wheel aligned with the rear manifold at the armoring machine. Optical fibers and reinforcing elements (such as aramid yarn) are placed on the active payout frame. The threading process begins: the optical fibers and reinforcing elements are threaded through the manifold holes in the manifold plate, passing through the clamping surfaces of the meter wheel and rubber wheel. They are then introduced through the rear manifold at the armoring machine and guided through the front outlet pipe to the take-up device. The armoring machine, take-up device, and active pay-out frame are then activated. After passing through the manifold channel in the manifold plate, the optical fibers and reinforcing elements are combined into a single bundle. Driven by the take-up device, the bundle moves forward, driving the meter wheel and rubber wheel to rotate simultaneously. An encoder converts the meter wheel's motion into an electrical signal, which is transmitted to a controller to achieve meter counting.

[0021] In this embodiment, the meter wheel is a axially grooved meter wheel made of metal with several weight-reducing through-holes in the main body. Due to its low density, it is lightweight and convenient to use. The rubber wheel is a bearing-mounted rubber wheel that mates with the circumferential grooves of the meter wheel. Together, the two enable efficient meter counting.

[0022] Meanwhile, the mounting plate 1 has fourth oblong through-holes 20 on either side, through which bolts pass to secure the mounting plate 1. These fourth oblong through-holes allow for adjustment of the mounting plate's left and right position, allowing the meter wheel and rubber wheel to align with the rear manifold of the armoring machine.

[0023] like Figure 1 、 Figure 2 As shown, the rubber wheel is configured as follows. The L-shaped vertical plate 7 is provided, and the adjustment frame 2 is a rectangular plate. A second oblong through-hole A11 is vertically provided on the upper portion of the adjustment frame 2. Third oblong through-holes B12 are provided on both sides of the upper portion of the adjustment frame 2. The third oblong through-holes B12 are arranged perpendicularly to and interconnected with the second oblong through-hole A11. The rear end of the convex fixed shaft 8 is disposed within the second oblong through-hole A11, and a long screw 13 is passed through the rear end. The two ends of the long screw 13 extend through the third oblong through-hole B12 and are locked by a nut. Loosening the nut allows the convex fixed shaft to move up and down through the two ends of the long screw, thereby driving the rubber wheel to move up and down toward or away from the meter wheel. Tightening the nut secures the rubber wheel in place.

[0024] However, considering that there are many reinforcing components and multiple incoming wires, the wires may be offset due to the different angles of the wire harness entering the wire junction hole. The meter wheel and rubber wheel only use point tangent clamping, which may cause the meter wheel and rubber wheel to not rotate, affecting the wire entry and meter counting. Therefore, the meter wheel and rubber wheel are staggered. Specifically, the L-shaped vertical plate 7 is provided with two pieces, the adjustment frame 2 is a concave frame, and the top of the adjustment frame 2 is provided with a positioning plate 14. The side of the positioning plate 14 near the meter wheel is provided with a movable plate 15 that can slide back and forth. The bottom surface of the movable plate 12 is in contact with the top surface of the adjustment frame. The movable plate 15 is vertically provided with a second oblong through hole A'11. The upper two sides of the movable plate 15 are provided with third oblong through holes B'12. The third oblong through holes B'12 are arranged perpendicularly to the second oblong through holes A'11 and are interconnected. The rear end of the convex fixed shaft 8 is provided in the second oblong through hole A'11, and the rear end is penetrated by a long screw 13. The two ends of the long screw 13 pass through the third oblong through hole B'12 and are locked by a nut. Loosening the nut, the two ends of the long screw can drive the convex fixed shaft to move up and down, thereby driving the rubber wheel to move up and down toward or away from the meter wheel. Tightening the nut fixes the rubber wheel. The movable plate can be used to adjust the front-to-back position of the rubber wheel. Moving the plate forward allows the rubber wheel and meter wheel to be staggered, typically by 3-5 mm. This design allows the upper rubber wheel to find the center point of the converging cable while also increasing the contact length between the converging cable, the rubber wheel, and the meter wheel. The converging cable is first centered on the rubber wheel before being moved to the meter wheel for metering. During fiber routing, the fiber under the upper wheel theoretically experiences greater pressure. The staggered arrangement of the meter wheel and rubber wheel ensures more stable routing of the fiber and reinforcement elements.

[0025] Furthermore, the movable plate is arranged in such a way that two sets of slide rails 16 are provided on the side of the positioning plate 14 close to the meter wheel 4, and two sets of support plates 17 are vertically provided on the rear side of the movable plate 15. The support plates 17 are provided with slide grooves 18 that cooperate with the slide rails 16. The movable plate 15 is arranged in front of the positioning plate 14 through the cooperation of the slide grooves and the slide rails. The top of the support plate 17 is threadedly connected with a locking bolt 19, and the locking bolt can tighten the slide rail to achieve fixation.
