[0026] Please refer to Figures 1-5 , a dust removal and wire arrangement mechanism for optical fiber raw winding, comprising two symmetrically arranged side support frames 1 as the support base of the entire mechanism. A connecting rod 2 is arranged between the two side support frames 1, which is used to strengthen the connection stability between the two side support frames 1, so that the entire mechanism is more firm. In addition, a stabilizing rod 6 with a rectangular cross section is further arranged between the two side support frames 1, the two ends of the stabilizing rod 6 are fixedly connected with the two side support frames 1 respectively, further enhancing the overall stability of the mechanism.

[0027] Two side support frame 1 is also provided with a screw rod transmission pair 3, both ends of the screw rod transmission pair 3 through the bearing and two side support frame 1 connection. Screw rod transmission pair 3 can convert rotary motion into linear motion, for the movement of the wire arrangement assembly 4 power. Screw rod transmission pair 3 on the screw nut seat is provided with wire arrangement assembly 4, when the screw rod transmission pair 3 work, screw nut seat will move along the screw, thus driving the wire arrangement assembly 4 moves. In order to ensure the stability of the wire arrangement assembly 4 moves, the base 401 is also provided with a rolling bearing 7, and the rolling bearing 7 is symmetrically provided with a group of up and down, two rolling bearings 7 are connected by bolts with the side of the base 401, two rolling bearings 7 are respectively with the upper and lower end face of the stabilizing bar 6, through the rolling bearing 7 and the stabilizing bar 6 cooperation, reduce the shake when the wire arrangement assembly 4 moves.

[0028] Wire arrangement assembly 4 contains the screw nut seat connected on the screw rod transmission pair 3 on the base 401, the dust removal box 402 connected with the base 401, the guide screw rod 403, two vertical guide screw nut seat 404, horizontal roller shaft 406 and adjusting handle 405.

[0029] Wire arrangement assembly 4 contains the screw nut seat connected on the screw rod transmission pair 3 on the base 401, the dust removal box 402 connected with the base 401. The base 401 plays a role in connecting the screw rod transmission pair 3 and supporting the dust removal box 402, and the dust removal box 402 is fixedly arranged on the upper end face of the base 401, and is used for dust removal operation on the optical fiber. The dust removal box 402 is also provided with two wire slot 411, and the optical fiber can pass in and out of the dust removal box 402 through the wire slot 411.

[0030] The guide screw rod 403 is a bidirectional screw rod, both ends of the guide screw rod 403 are connected with the two vertical sides of the dust removal box 402 through bearings, and one end of the guide screw rod 403 penetrates through the side of the dust removal box 402 and is connected with the adjusting handle 405. Rotating the adjusting handle 405 can make the guide screw rod 403 rotate. The vertical guide screw nut seat 404 is L-shaped, one side of the lower part of the vertical guide screw nut seat 404 is connected with the guide screw rod 403, the other end is connected with the horizontal roller shaft 406 and can slide freely on the horizontal roller shaft 406. Since the guide screw rod 403 is a bidirectional screw rod, when the guide screw rod 403 rotates, the two vertical guide screw nut seats 404 will move relatively or oppositely along the guide screw rod 403.

[0031] The upper end of each of the two vertical guide screw-nut seats 404 is provided with a guide vertical stop roller shaft 407, the inside of the guide vertical stop roller shaft 407 is provided with a connecting shaft 408, and the upper and lower ends of the connecting shaft 408 are connected with the inner wall of the vertical stop roller shaft 407 through bearings, and the bottom end of the connecting shaft 408 is fixedly connected with the upper end surface of the vertical guide screw-nut seat 404. The guide vertical stop roller shaft 407 can move with the movement of the vertical guide screw-nut seat 404, and plays a guiding and limiting role on the optical fiber, and ensures the position accuracy of the optical fiber during the arrangement process.

[0032] One side of the two vertical stop roller shafts 407 is also provided with a horizontal stop roller shaft 409, and the two ends of the horizontal stop roller shaft 409 are connected with the two vertical side walls of the dust removal box 402 through bearings. The horizontal stop roller shaft 409 cooperates with the guide vertical stop roller shaft 407 to further guide and limit the arrangement of the optical fiber, so that the optical fiber can be arranged neatly.

[0033] The side of the dust removal box 402 close to the horizontal stop roller shaft 409 is also provided with an electrostatic elimination rod 5, which can eliminate the static electricity on the surface of the optical fiber, and prevent dust from being adsorbed on the optical fiber due to static electricity. The top and both sides of the dust removal box 402 are provided with dust suction pipe connecting holes 410 connected with external dust removal equipment, and the dust in the dust removal box 402 is sucked away through connection with the external dust removal equipment, so as to achieve effective dust removal of the optical fiber.

[0034] Working principle:

[0035] The screw rod transmission pair 3 is the core driving component of the arrangement action, and its two ends are stably arranged on the two symmetrical side support frames 1 through bearings. When an external power source is connected, the screw rod of the driving screw rod transmission pair 3 rotates, and according to the basic principle of screw rod transmission, the screw nut seat will produce linear displacement along the axial direction of the screw rod. The base 401 in the arrangement assembly 4 is fixedly connected with the screw nut seat, so that the entire arrangement assembly 4 can move synchronously with the screw nut seat.

[0036] The guide screw rod 403 located in the dust removal box 402 plays a key role in fine adjustment of the arrangement position. The guide screw rod 403 is a bidirectional screw rod, and the special thread structure makes the two vertical guide screw-nut seats 404 connected with it rotate in opposite directions or in the same direction when the adjusting handle 405 connected with one end of it is rotated. Since the vertical guide screw-nut seat 404 is L-shaped, one end thereof is threadedly connected with the guide screw rod 403, and the other end is connected with the horizontal roller shaft 406 and can freely slide on the horizontal roller shaft 406. This connection mode ensures that the vertical guide screw-nut seat 404 can move with the guide screw rod 403 without interfering with the supporting function of the horizontal roller shaft 406 on the optical fiber.

[0037] The upper end of the two vertical guide screw nut bases 404 is fixedly connected with a guide vertical stop roller shaft 407, a connecting shaft 408 in the guide vertical stop roller shaft 407 is connected with the inner wall of the guide vertical stop roller shaft 407 through a bearing, and the bottom end of the connecting shaft 408 is fixed with the upper end surface of the vertical guide screw nut base 404, which ensures that the guide vertical stop roller shaft 407 can be flexibly moved with the vertical guide screw nut base 404 and can be freely rotated around the connecting shaft 408. During the arrangement of the optical fibers, the optical fibers pass between the two guide vertical stop roller shafts 407, and the transverse arrangement position of the optical fibers is accurately controlled with the adjustment of the position of the guide vertical stop roller shaft 407, so that the arrangement of the optical fibers is neat and compact.

[0038] When the optical fibers enter the dust removal box 402 from the wire arrangement slot 411 on the dust removal box 402, the first encountered is the electrostatic elimination rod 5 located on the side close to the horizontal stop roller shaft 409. In the electrified working state, the electrostatic elimination rod 5 releases a large amount of positive and negative ions to the surrounding space, and the ions can quickly neutralize the static electricity carried on the surface of the optical fibers. Since static adsorption is one of the important reasons for dust adhering to the surface of the optical fibers, after the static electricity is eliminated, the dust is more easily separated from the surface of the optical fibers.

[0039] At the same time, the dust suction pipe connecting holes 410 arranged on the top and both sides of the dust removal box 402 are connected with the external dust removal equipment. After the external dust removal equipment is started, a strong negative pressure suction force is generated at the dust suction pipe connecting holes 410, so that the dust separated from the surface of the optical fibers and suspended in the box is timely sucked away, collected and treated through the filtering system of the external dust removal equipment, so that the optical fibers are prevented from being polluted again, and the efficient dust removal purpose is achieved.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0041] In addition, it should be understood that, although the present application is described in the embodiments, each embodiment does not contain only one independent technical solution, and the description manner of the specification is only for the sake of clarity, and the person skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments which can be understood by the person skilled in the art.
