[0040] In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] The technical solution of the present application is applied to the long-distance horizontal transmission of optical cable water-blocking tapes. This solution ensures that the optical cable water-blocking tapes are in a tensioned state during transmission and the tensile force is not too large to cause overlapping or flipping of the optical cable water-blocking tapes.

[0042] refer to Figure 1 and Figure 2 , Figure 1 This is a three-dimensional diagram of a water-blocking tape limiting device of the present application. Figure 2 This is a schematic cross-sectional view of another perspective of a water-blocking tape limiting device of the present application. Figure 1 and Figure 2 As shown, a water-blocking tape limiting device includes a supporting device 10, at least one set of counterweight limiting devices 20 slidably connected to the supporting device 10, a blowing device 30 detachably connected to the supporting device 10, and a multi-directional camera detection device 40 fixed to the supporting device 10. The supporting device 10 includes a supporting frame 11 and a guide rail frame 12 connected to the support frame 11. Here, the optical cable water blocking tape is rotationally limited within a certain range by the counterweight limiting device 20, and at the same time, the optical cable water blocking tape is appropriately pressed downward to prevent the optical cable water blocking tape from turning over or overlapping during the unwinding process, thereby ensuring that the optical cable water blocking tape can be smoothly transported and reducing its scrap rate. In addition, since the counterweight limiting device 20 is slidably connected to the supporting device 10, and due to the static friction between the gravity of the sliding structural member inside the counterweight limiting device 20 and the matching structural member, the counterweight limiting device 20 can be kept in the position without moving when it slides to the desired position, so that the counterweight limiting device 20 can be adjusted according to the site According to the actual situation of the optical cable water-blocking tape, it slides to the corresponding position and maintains it to limit the rotation and longitudinal downward pressure of the optical cable water-blocking tape. At the same time, under the action of the blowing device 30, the position of the optical cable water-blocking tape being unwound, the position of the tape being retracted and any other positions can be blown as long as it meets the requirements before passing through the counterweight limiting device 20, so that the optical cable water-blocking tape can be spread out flat during the transmission process, further effectively reducing the frequency of the optical cable water-blocking tape being turned over or overlapped during the transmission process, thereby reducing the product scrap rate. During application, technical personnel in this field can configure multiple sets of counterweight limiting devices according to the transmission distance, and the rotation angles of the optical cable water-blocking tapes in adjacent counterweight limiting devices can be different.

[0043] Continue to refer Figure 2 , for reference Figure 3 , Figure 3 This is a three-dimensional diagram of a counterweight limiting device in a water-blocking tape limiting device of the present application. Figure 2 and Figure 3 As shown, the counterweight limiting device 20 includes a sliding mechanism 21, a connecting mechanism 22, and a rotation limiting mechanism 23 connected to the connecting mechanism 22. The sliding mechanism 21 cooperates with the guide rail frame 12. One end of the connecting mechanism 22 is connected to the sliding mechanism 21, and the other end is connected to the rotation limiting mechanism 23. Here, the connecting mechanism 22 is a soft rope or a vertical telescopic rod. The top of the vertical telescopic rod is fixedly connected to the sliding mechanism to enable the rotation limiting mechanism 23 to move freely in the longitudinal direction.

[0044] Continue to refer Figure 3 , for reference Figure 4 and Figure 5 , Figure 4 This is a schematic cross-sectional view of a counterweight limiting device in a water-blocking tape limiting device of the present invention from another perspective. Figure 5 yes Figure 4 The enlarged view of circle B is shown. Figure 3 、 Figure 4 and Figure 5 As shown, the rotation limiting mechanism 23 includes a limiting ring 231 and a double-roller rotation limiting assembly 232 connected to the inside of the limiting ring 231, and the inner side wall of the limiting ring 231 is provided with a slideway 231A. Here, the double-roller rotation limit assembly 232 rotates along the slide 231A on the inner wall of the limit ring 231 to realize the rotation limit of the optical cable water blocking tape. At the same time, the limit ring 231 is a metal entity with appropriate weight. Under the action of the limit ring 231's own gravity, the optical cable water blocking tape is pressed downward longitudinally to avoid large-scale shaking of the optical cable water blocking tape during long-distance transportation. In addition, the slide 231A is an arc-shaped slide 231A to realize the limitation of the position of the double-roller rotation limit assembly 232 within a certain range. Furthermore, the rotation angle of the double-roller rotation limit assembly 232 is between 0° and 60°. If multiple sets of counterweight limit devices 20 are configured as needed, the multiple sets of double-roller rotation limit assemblies 232 rotating within a certain range cooperate with each other to increase the limit point of the optical cable water blocking tape, thereby better avoiding overlapping and flipping of the tape.

[0045] Continue to refer Figure 5 , for reference Figure 6 , Figure 6 This is a three-dimensional diagram of a double-roller rotation limiting assembly in a water-blocking tape limiting device of the present application. Figure 5 and Figure 6As shown, the double-roller rotation limit assembly 232 includes a fixed plate 2321, two rollers 2322 and a rotating head 2323 connected to the fixed plate 2321. The two rollers 2322 are connected to the inner wall of the fixed plate 2321, and the rotating head 2323 is connected to the outer wall of the fixed plate 2321. The rollers 2322 can rotate freely inside the limiting ring 231, and there is a gap 232A between the two rollers 2322. The gap 232A cooperates with the rotating head 2323 and the slide 231A to realize the real-time correction of the optical cable water blocking tape through the rotation of the double-roller rotation limit assembly 232 when the optical cable water blocking tape flips over. In addition, the shape of the fixed plate 2321 is arc-shaped, so that the fixed plate 2321 and the two rollers 2322 can rotate at the same time, avoiding interference caused by the fixed plate 2321 during the rotation. Here, the optical cable water-blocking tape passes through the limit ring 231 and the gap 232A between the two rollers 2322 from the unwinding end to the winding end. When the optical cable water-blocking tape passes through the gap 232A between the two rollers 2322, the two rollers 2322 clamp the optical cable water-blocking tape and roll with the optical cable water-blocking tape. At the same time, with the mutual cooperation of the rotating head 2323 and the slide 231A, the turning frequency of the optical cable water-blocking tape is reduced, and the frequency of overlapping tapes is reduced under the action of the blowing device 30.

[0046] Continue to refer Figure 2 , for reference Figure 7 , Figure 7 This is a three-dimensional diagram of a blowing device in a water-blocking tape limiting device of the present application. Figure 2 and Figure 7 As shown, the blowing device 30 includes a detachable mounting frame 31, a blowing mechanism 32 and a rotatable and adjustable directional air outlet mechanism 33. The blowing mechanism 32 is fixed to the inside of the mounting frame 31. The directional air outlet mechanism 33 is rotatably connected to the blowing mechanism 32. The mounting frame 31 includes a fixing assembly 311 and a supporting assembly 312 connected to the fixing assembly 311. Here, the fixing assembly 311 cooperates with the supporting frame 11 to determine the blowing position required for the optical cable water blocking tape according to needs, to adjust the position of the blowing device 30, and to fix the entire mounting frame 31 through the fixing assembly 311. The supporting assembly 312 is used to support the blowing mechanism 32. In addition, the directional air outlet mechanism 32 can be rotated according to the stacking direction of the optical cable water blocking tape, thereby adjusting the direction of the air outlet, so as to shake the stacked optical cable water blocking tapes by wind force, thereby changing the optical cable water blocking tapes from a folded state to a flat state. The blowing device of the present application can also be combined with the heat dissipation structure in the optical cable production process, using a passive blowing method, for example, the heat dissipation outlet during the temperature reduction process of the optical cable production process is connected to the blowing device.

[0047] refer to Figure 8 , Figure 8This is a three-dimensional diagram of the mounting frame in the water-blocking tape limiting device of the present application. Figure 8 As shown, the support assembly 312 includes an L-shaped support plate 3121 and a support ring 3122 connected to the support plate. Specifically, the blower mechanism 32 is sleeved within the support ring 3122 and fixed to the support ring 3122 to support the blower mechanism 32. The L-shaped support plate 3121 is used to support the support ring 3122 within a limited space, thereby supporting the blower mechanism 32 within a limited space.

[0048] Continue to refer Figure 1 , for reference Figure 9 , Figure 9 yes Figure 1 The enlarged view of circle A is shown. Figure 1 and Figure 9 As shown, the multi-directional camera detection device 40 includes a multi-directional connecting mechanism 4122 and a camera mechanism 42 connected to the multi-directional connecting mechanism 4122. The multi-directional connecting mechanism 4122 includes a main connecting rod 411, at least one group of sub-connecting rods 412 and a connecting block 413 connected to the sub-connecting rod 412. A group of sub-connecting rods 412 includes at least three sub-connecting rods 412. The camera mechanism 42 is connected to the final sub-connecting rod 412. Here, through the mutual cooperation between the auxiliary connecting rod 412 and the connecting block 413, multi-angle adjustment of the camera mechanism 42 is realized, including telescopic and 360° steering, so that when the camera mechanism 42 is placed at different positions of the optical cable water blocking tape, its position can be adjusted to multiple angles for shooting, thereby improving the richness of the shooting content. In addition, the installation of the camera mechanism 42 realizes that during the processing process, there is no need for manual supervision to observe the status of the optical cable water blocking tape. It is only necessary to use an external status analysis device and an alarm device to analyze the status of the camera mechanism 42 in real time. When there is an abnormality in the analysis, the alarm device will sound an alarm, and the staff will handle it, which effectively reduces labor costs. The abnormalities include but are not limited to the turning over and overlapping of the optical cable water blocking tape and large-scale shaking during the transmission process.

[0049] Here, through the counterweight limit device 20 that is slidably connected to the support device 10 and the multi-directional camera detection device 40 fixed to the support device 10, and the guide rail frame 12 in the support device 10 is connected to the support frame 11, the sliding mechanism 21 in the counterweight limit device 20 cooperates with the guide rail frame 12, and one end of the connecting mechanism 22 is connected to the sliding mechanism 21, and the other end is connected to the rotation limit mechanism 23, so as to realize the optical cable water-blocking tape in the process of covering the optical cable, reduce the scrap rate of the product, and eliminate the need for manual supervision, thereby reducing labor costs.

[0050] For ease of understanding, the working principle of the present application is further described as follows: When the water-blocking tape limiting device is used, the counterweight limiting device 20 of the optical cable water-blocking tape is set up through the support frame 11 of the supporting device 10, and after the optical cable water-blocking tape is set up at the tape-unwinding end, the tape head of the optical cable water-blocking tape is sequentially passed through the gap 232A between the limiting ring 231 and the two rollers 2322 to transmit the optical cable;

[0051] Afterwards, the blowing device 30 takes the position close to the unwinding end of the optical cable water-blocking tape as the initial position and blows air on the optical cable water-blocking tape. In the daily use of the blowing device 30, according to the position where the optical cable water-blocking tape needs to be blown by the blowing device 30 to be shaken and flattened, the blowing device 30 is adjusted to the desired position by adjusting the mounting frame 31, and the air outlet direction of the directional air outlet mechanism 33 is adjusted, so that during the conveying process of the optical cable water-blocking tape, the optical cable water-blocking tape is shaken by wind force, thereby flattening the overlapped optical cable water-blocking tape.

[0052] At the same time, under the action of the counterweight limiting device 20, the optical cable water blocking tape is rotationally limited, and under the action of the weight of the limiting ring 231 itself, the optical cable water blocking tape is longitudinally pressed downward to limit the position, and according to the analysis device external to the multi-directional camera detection device 40, after analyzing the abnormal shaking of the optical cable water blocking tape, the alarm device promptly alarms, and under the mutual cooperation of the sliding mechanism 21 and the guide rail frame 12, the staff moves the counterweight limiting device 20 to the position where the optical cable water blocking tape shakes abnormally, eliminating the risk of abnormal shaking of the optical cable water blocking tape, and after the abnormal shaking is eliminated, the staff again moves the counterweight limiting device 20 to the middle position of the guide rail frame 12, and the middle position is the initial position;

[0053] In addition, after the optical cable water blocking tape passes through the rotation limiting mechanism 23, the rotation limiting mechanism 23 is adjusted in real time within a certain range according to the turning trend of the optical cable water blocking tape to reduce the turning frequency of the optical cable water blocking tape.
