[0002] The optical cable sheath is a protection for the tensile elements, water-blocking elements, buffer materials, flame-retardant materials, etc. in the optical cable structure. The optical cable sheath layer is the outer, effective and comprehensive protective layer of the optical cable. It has a great influence on the performance of the optical cable, and it is required that the sheath layer should be continuous, complete, insulated, and the surface should be round and smooth. There will be problems of surface integrity defects and bulges in the production of the sheath production line, and it is necessary to mark the surface integrity defects and bulges of the sheath layer.

[0026] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the drawings in the specification.

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0029] Embodiment 1, refer to Figure 1-2, which is the first embodiment of the utility model, and this embodiment provides a limiting mechanism, including a clamping assembly 100, and a driving assembly 200 disposed in the clamping assembly 100;

[0030] The clamping assembly 100 includes a box body 101, a first positioning roller 102 is arranged inside the box body 101, a second positioning roller 103 is arranged on the upper part of the first positioning roller 102, and a wire inlet hole 104 and a wire outlet hole 105 are arranged on the box body 101;

[0031] The inlet hole 104 and the outlet hole 105 are respectively located on two opposite sides of the box body 101, and the inlet hole 104 and the outlet hole 105 are at the same height, and the upper surface of the first positioning roller 102, the lower surface of the inlet hole 104 and the lower surface of the outlet hole 105 are flush.

[0032] The driving assembly 200 includes a housing 201 , a piston 202 is disposed inside the housing 201 , a connecting rod 203 is disposed below the piston 202 , a spring 204 is sleeved outside the connecting rod 203 , an air inlet 205 is disposed on the upper part of the housing 201 , and an air outlet 206 is disposed in the middle part of the housing 201 .

[0033] The air inlet 205 is connected to an external air source.

[0034] Furthermore, the clamping assembly 100 further includes a first mounting frame 106 , which is fixedly disposed on the inner wall of the box body 101 , and the first positioning roller 102 is rotatably mounted on the first mounting frame 106 .

[0035] Furthermore, the clamping assembly 100 further includes a second mounting frame 107 , the second positioning roller 103 is rotatably mounted on the second mounting frame 107 , and the bottom of the connecting rod 203 passes through the housing 201 and is connected to the second mounting frame 107 .

[0036] The first mounting frame 106 is fixed on the inner wall of the box body 101 and is used to support and install the first positioning roller 102; the second mounting frame 107 is fixed on the lower end of the connecting rod 203, and the second mounting frame 107 is driven up and down by the driving component 200 to adjust the position between the first positioning roller 102 and the second positioning roller 103.

[0037] Usage process: The optical cable enters the box 101 from the cable inlet hole 104, passes through the first positioning roller 102 and the second positioning roller 103, and then passes through the box 101 from the cable outlet hole 105. Inside the box 101, the optical cable is between the first positioning roller 102 and the second positioning roller 103, so that the first positioning roller 102 and the second positioning roller 103 form upper and lower limits for the optical cable, thereby limiting the lateral jumping of the optical cable.

[0038] The driving assembly 200 drives the second mounting frame 107 to move up and down, and adjusts the position between the first positioning roller 102 and the second positioning roller 103 to adapt to the clamping and limiting of optical cables with different outer diameters.

[0039] The optical cable is clamped between the first positioning roller 102 and the second positioning roller 103 to reduce the up and down bouncing of the optical cable, so as to facilitate marking of the surface defects and bulges of the optical cable sheath layer; the distance between the first positioning roller 102 and the second positioning roller 103 is adjusted by the driving component 200 to meet the clamping limit of optical cables of various outer diameters.

[0040] Example 2, reference Figure 1-2 , which is the second embodiment of the utility model. Different from the previous embodiment, the roller surfaces of the first positioning roller 102 and the second positioning roller 103 are both inwardly concave arc surfaces.

[0041] The roller surfaces of the first positioning roller 102 and the second positioning roller 103 are arc surfaces, which have a certain limiting effect on the left and right shaking of the optical cable, further reducing the shaking of the optical cable and facilitating the marking of the optical cable.

[0042] Furthermore, the wire inlet hole 104 and the wire outlet hole 105 are respectively located on two opposite sides of the box body 101 , and the first positioning roller 102 and the second positioning roller 103 are respectively located on the upper and lower sides of the wire outlet hole 105 .

[0043] Usage process: The optical cable passes through the first positioning roller 102 and the second positioning roller 103. The roller surfaces of the first positioning roller 102 and the second positioning roller 103 are inwardly concave arc surfaces, so that the middle gap between the first positioning roller 102 and the second positioning roller 103 is the largest, and the gap gradually decreases from the middle to both sides. The optical cable is clamped in the middle gap between the first positioning roller 102 and the second positioning roller 103. As the gaps on both sides become smaller, the optical cable is restricted from shaking to both sides.

[0044] Example 3, reference Figure 1-5 , which is the third embodiment of the utility model, this embodiment provides an optical cable marking device, including a limiting mechanism, and also includes an ink supply mechanism 300 arranged on one side of the box body 101, the discharge end of the ink supply mechanism 300 is connected to the inkjet mechanism 400, the air inlet end of the inkjet mechanism 400 is connected to the air supply mechanism 500, and a supporting mechanism 600 is arranged at the bottom of the box body 101.

[0045] Furthermore, the ink supply mechanism 300 includes a support frame 301 , an ink container 302 is disposed on one side of the top of the support frame 301 , and an ink inlet tube 303 is disposed on the ink container 302 .

[0046] The support frame 301 is in the shape of a vertically arranged long rod, and the ink container 302 is fixed on the top of the support frame 301 .

[0047] Further, the inkjet mechanism 400 includes a nozzle body 401 disposed inside the box body 101. A nozzle 402 is provided on the nozzle body 401. The nozzle body 401 is connected to the ink inlet pipe 303, and an air supply pipe 403 is provided between the nozzle body 401 and the air outlet 206.

[0048] The nozzle 402 is specifically disposed at the lower part of the nozzle body 401. The height of the ink container 302 is higher than that of the nozzle body 401, so that the ink in the ink container 302 flows into the nozzle body 401 by gravity.

[0049] Further, the air supply mechanism 500 includes an air compressor 501. An air inlet pipe 502 is provided on the air compressor 501, and the air inlet pipe 502 is communicated with the air inlet 205.

[0050] The air compressor 501 provides air with a certain pressure for the nozzle body 401, so that the inkjet printing has a certain air pressure and the inkjet printing speed is increased.

[0051] Further, the support mechanism 600 includes a base 601 fixed to the lower part of the box body 101. A waste ink collection container 602 is provided on the base 601, and a recovery pipe 603 is provided between the waste ink collection container 602 and the box body 101.

[0052] The base 601 is used to install and support the entire device. The box body 101 is located outside the nozzle body 401 and acts as a fence to prevent the inkjet printing ink from spreading out. The ink generated by the inkjet printing accumulates in the box body 101 and flows into the waste ink collection container 602 through the recovery pipe 603.

[0053] During the use process: The air inlet pipe 502 sends air with a certain pressure into the inside of the housing 201. The piston 202 moves downward under the air pressure, drives the connecting rod 203 to move downward, and further drives the second positioning roller 103 to move downward. The optical cable is clamped between the first positioning roller 102 and the second positioning roller 103. At the same time, when the piston 202 moves down to the air outlet 206, the high-pressure gas in the housing 201 enters the nozzle body 401 through the air supply pipe 403 and sprays out from the nozzle 402 together with the ink. After marking, the air inlet pipe 502 stops supplying air, and the elastic force of the spring 204 is released, driving the piston 202 to rise, and further driving the second positioning roller 103 to rise. The second positioning roller 103 is disengaged from the optical cable.

[0054] During inkjet printing, the second positioning roller 103 descends to limit the optical cable between the first positioning roller 102 and the second positioning roller 103. After inkjet printing, relying on the release of the elastic force of the spring 204, the second positioning roller 103 rises to avoid contact between the second positioning roller 103 and the optical cable and prevent the freshly printed ink from being erased. The freshly printed ink has not dried yet and is easily erased.

[0055] The air supply mechanism 500 drives the limit mechanism and the inkjet mechanism 400 to work successively, realizing the linkage of the limit mechanism and the inkjet mechanism 400, achieving the effect of "printing positioning and avoiding after printing", facilitating printing while improving the accuracy of the printing position and preventing the printed marks from being erased.
