Description
Technical field
The utility model relates to a kind of optical fiber proof-tester, particularly to the disconnected fine treating apparatus of screening machine.
Background technology
In the optical fiber screening process, disconnected fine phenomenon appears often, and the optical fiber of high-speed motion can fly in the take-up bucket that configures in advance because of inertia after fracture suddenly.But there is a defective in this take-up bucket promptly: be not enough to be thrown into the take-up bucket when the optical fiber speed of coming out from the unwrapping wire traction wheel is very low, when perhaps having expired in the take-up bucket, optical fiber can hang down.If the optical fiber on the very short unwrapping wire fiber reel that does not touch in the rotation of sagging length, then there is not accident to take place, if sagging length is oversize, touched optical fiber on the unwrapping wire fiber reel in the rotation so under the effect of static or other reason, sagging optical fiber can be gone into to draw drum by strand, optical fiber on the coup injury dish, along with preform make increasing, the optical fiber that draws is also more and more longer, from initial 200km 1000km till now, so big draw drum original take-up bucket when disconnected fibre takes place can not meet the demands, and sagging optical fiber directly is rolled onto on the draw drum, damage one deck or which floor optical fiber.
The utility model content
Technical scheme to be solved in the utility model is, provides a kind of optical fiber that can avoid emitting from the unwrapping wire traction wheel after the fibercuts to be wound on the unwrapping wire fiber reel, damages the screening machine of the optical fiber on it, to avoid the damage of disconnected fine back to optical fiber on the draw drum.
The utility model solve the technical problem the technical scheme that is adopted, and a kind of optical fiber proof-tester is provided, and comprises unwrapping wire traction wheel, wire-crossing wheel and draw drum, above draw drum, is provided with a spacer assembly.
Described spacer assembly is a container, and first common tangent of described unwrapping wire traction wheel wheel shaft and wire-crossing wheel wheel shaft is non-contacting to pass described spacer assembly.Described spacer assembly is the cylinder of a hollow, described cylinder one end sealing, and the intersection point place of described cylinder and described first common tangent has a hole.Described spacer assembly is the cylinder of a hollow, described cylinder one end sealing, and described cylinder has a breach, and described breach extends to the intersection point of cylinder and described first common tangent from the cylinder open end.Described spacer assembly also can be a hollow, semi-enclosed solid.Described spacer assembly is the rectangular parallelepiped box, and respectively there is a breach two sides about described rectangular parallelepiped box, and also there is a breach front of box, and the breach of three faces communicates.Described spacer assembly also can be a division board, and described division board has a breach on the position of optical fiber process.Described division board is installed on the protective door.Described spacer assembly also can be a protective cover, and described protective cover is installed in the draw drum top.
In fact, the utility model does not need special requirement to the geometric configuration of described spacer assembly, as long as the draw drum of sagging optical fiber and below is kept apart, can reach satisfied effect.Described spacer assembly can be a solid hollow, semi-enclosed, because optical fiber is loose being deposited in this spacer assembly, understanding to " semiclosed " should be, as long as can limit the space of the optical fiber of accumulation, the material that constitutes this spacer assembly can be a thin plate, also can be Web materials, for example, wire netting." first common tangent " described in the utility model is when producing optical fiber, the position of the optical fiber between unwrapping wire traction wheel and wire-crossing wheel, in other words, the path of fibre movement.
The beneficial effects of the utility model are, fine space is resolved in restriction, alleviate even avoid resolving fine harmful effect of twining finished product optical fiber, have avoided unnecessary waste, have improved yield rate.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Embodiment
Referring to Fig. 2.The wire-crossing wheel 1 of optical fiber proof-tester passes spacer assembly 3 with a common tangent of wire-crossing wheel 2, and just optical fiber will pass described spacer assembly 3 in optical fiber production process.Because the optical fiber high-speed motion, described spacer assembly 3 can not have contacting physically with optical fiber, and therefore, this paper is called passing of " noncontact ".In the present embodiment, spacer assembly 3 will " shroud " on this section optical fiber.For the screening machine that does not put into production as yet, owing to do not have optical fiber as reference, so with the position of optical fiber, promptly the common tangent of two wire-crossing wheels is described, this paper is referred to as " first common tangent ".
The utility model is to the shape of described spacer assembly 3 and have no special requirements, and as an embodiment, can adopt a semi-enclosed cylinder, and cylindrical wall has a breach, and perhaps deep seam is so that optical fiber can pass through from this cylinder is expedite.In addition, if same effect also can be realized in the hole of opening a location-appropriate on a semi-enclosed cylinder.Described " location-appropriate " is meant that first common tangent can pass through from this hole.
As embodiment 2, shown in Fig. 2,3, spacer assembly 3 is the box of a rectangular shape, and respectively there is a breach two sides about described box, and also there is a breach front of box, and the breach of three faces communicates, so that optical fiber passes through from box.If optical fiber ruptures, can assemble in box is loose one.Disconnected fine for the ease of taking out, can open the breach of a side bigger.The breach of box front is for the ease of producing starting stage importing optical fiber.
As embodiment 3, as shown in Figure 4, spacer assembly 3 is the division board of a section for " L " shape, and a breach is arranged in the position that optical fiber passes through.Described division board can be installed on the main body of screening machine.Because screening machine has a protective door, division board also can be installed on the protective door 5, as shown in Figure 5.Described protective door can rotate around the axle of A, B point-to-point transmission.Be in closed condition at protective door, when just screening machine was in running order, the position of described division board was in the top of draw drum.
As embodiment 4, spacer assembly is a protective cover that places the draw drum top, leaves a breach on the described protective cover, passes for optical fiber.The shape of protective cover needn't limit, as long as sagging optical fiber and draw drum can be kept apart.
