[0002] In an optical splitter, the "empty conduit" generally refers to the optical fiber duct used for optical fiber signal transmission, typically the protective conduit for optical cables or the conduit used for cabling. In an optical splitter system, signals are transmitted from one place to another via optical fiber, and the "empty conduit" is the physical channel providing this signal transmission, possessing the following characteristics and functions:

[0003] Protective: The hollow tube can effectively protect the optical fiber from the influence of the external environment, such as humidity, temperature changes and mechanical damage;

[0004] Ease of installation: During the cabling process, the open conduit provides a clear path, making it easier to install, maintain, and replace fiber optic cables;

[0005] Adaptability: Different conduit designs are suitable for different application requirements, such as outdoor and indoor fiber optic cable laying;

Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0054] Example 1

[0055] like Figures 1 to 7 As shown, an optical splitter empty tube cutting device is used to replace manual cutting of empty tubes used for connecting optical splitters. The device includes a cutting frame 1, with a tube receiving mechanism connected to the top of the frame 1 for receiving and placing empty tubes. The receiving mechanism transports the empty tubes to a straightening mechanism via a conveying mechanism. The empty tubes are then cut to the required length by the cutting mechanism under the action of the straightening mechanism. The conveying mechanism, straightening mechanism, and cutting mechanism are all mounted on the cutting frame. The empty tubes sequentially move from the receiving mechanism, through the conveying mechanism and straightening mechanism, to the cutting mechanism, where they are bundled and cut to the required length in one operation, thereby improving production efficiency.

[0056] Furthermore, the cutting mechanism includes a first cutting take-up rod 21 and a second cutting take-up rod 22. The bottom end of the first cutting take-up rod 21 is rotatably connected to a first electric slider via a bearing. The first electric slider is horizontally slidable on the bottom surface of the empty tube storage tray 2. The bottom end of the second cutting take-up rod 22 is provided with a second connecting electric slider. The second connecting electric slider is horizontally slidable on the bottom surface of the empty tube storage tray 2. The bottom end of the second cutting take-up rod 22 rotatably passes through the second connecting electric slider via a bearing, and its end is connected to the output end of a servo motor via a shaft connector. The second cutting and take-up rod 22 is driven to rotate by a servo motor, and the empty tube is wound and taken up by the first cutting and take-up rod 21 and the second cutting and take-up rod 22. At the same time, a cutting cylinder 23 is movably installed on the bottom surface of the empty tube storage tray 2. The output end of the cutting cylinder 23 is connected to a cutting scissor for cutting the empty tube wound and taken up by the first cutting and take-up rod 21 and the second cutting and take-up rod 22. The bottom end of the cutting cylinder 23 is connected to the output end of the rotary cylinder, and the cutting cylinder is driven to rotate by the rotary cylinder. The cylinder body of the rotary cylinder is connected to the bottom surface of the empty tube storage tray 2 via a guide rail that can be raised and lowered.

[0057] In this embodiment, the empty tube to be cut is sequentially taken from the tube receiving mechanism, conveyed by the conveying mechanism, and straightened by the straightening mechanism to the cutting mechanism. One end of the empty tube is wound around and tied between the first cutting take-up rod 21 and the second cutting take-up rod 22, and the end of the empty tube is tied to the second cutting take-up rod 22. The second cutting take-up rod 22 is rotated by controlling the servo motor, thereby causing the empty tube to wind and rotate around the first cutting take-up rod 21 and the second cutting take-up rod 22. After a certain number of turns, the cutting cylinder 23 is controlled to move, cutting the empty tube with a certain number of turns between the first cutting take-up rod 21 and the second cutting take-up rod 22 into segments in one go, thereby achieving the purpose of rapid segmentation. Furthermore, the first cutting and take-up rod 21 is horizontally movable on the bottom surface of the empty tube storage tray 2 via the first electric slider, thereby adjusting the distance between the first cutting and take-up rod 21 and the second cutting and take-up rod 22 as needed, thereby adjusting the length of the cut empty tube segments to meet the requirements of the cut empty tube length.

[0058] Example 2

[0059] Based on Embodiment 1, the tube receiving mechanism includes an empty tube rotating roller 31 for receiving and releasing empty tubes, which is rotatably mounted on the top of the cutting machine frame 1; a first empty tube receiving roller 32 is provided below the empty tube rotating roller 31, which is rotatably connected to the upper side wall of the cutting machine frame 1; a second empty tube receiving roller 33 is provided on the side of the first empty tube receiving roller 32 near the empty tube receiving tray 2, which is also rotatably connected to the upper side wall of the cutting machine frame 1.

[0060] In this embodiment, the rolled empty tubes are passed through the empty tube rotating roller 31, and one end of the empty tube passes through the first receiving empty tube rotating roller 32 and the second receiving empty tube rotating roller 33 in an "S" shape, and then passes through the conveying mechanism.

[0061] Example 3

[0062] Furthermore, the conveying mechanism includes a first conveying guide cylinder 41 and a second conveying guide cylinder 42 that are hollowly arranged; the first conveying guide cylinder 41 and the second conveying guide cylinder 42 are relatively movable and coaxially arranged; the end of the first conveying guide cylinder 41 away from the second conveying guide cylinder 42 is connected to a first guide limiting sleeve 411 that is hollowly arranged, and the top of the end of the first guide limiting sleeve 411 away from the first conveying guide cylinder 41 is rotatably connected to a first movable guide shaft, and the first conveying guide cylinder 41 can be horizontally moved and connected to the cutting machine frame; at the same time, the end of the second conveying guide cylinder 42 away from the first conveying guide cylinder 41 is connected to a second guide limiting sleeve 421 that is hollowly arranged, and the top of the end of the second guide limiting sleeve 421 away from the second conveying guide cylinder 42 is rotatably connected to a second movable guide shaft, and the second conveying guide cylinder 42 can be horizontally moved and connected to the cutting machine frame 1.

[0063] The empty pipe passes through the conveying mechanism, enters the first guide limiting sleeve 411 through the first movable guide shaft, passes through the first conveying guide cylinder 41 from the first guide limiting sleeve 411, enters the second guide limiting sleeve 421 from the second conveying guide cylinder 42, and then moves through the second movable guide shaft set at the other end of the second guide limiting sleeve 421.

[0064] Furthermore, the first conveying guide cylinder 41 of this configuration has a first sliding cylinder 412 connected to the end away from the second conveying guide cylinder 42. The first sliding cylinder 412 is horizontally slidable and connected to the first connecting block. One side of the first connecting block is connected to the output end of the first horizontal push rod 413. The first horizontal push rod 413 drives the first connecting block to move horizontally. The housing of the first horizontal push rod 413 is connected to the cutting machine frame 1 through connecting bolts. The second conveying guide cylinder 42 has a second sliding cylinder 422 connected to the end away from the first conveying guide cylinder 41. The second sliding cylinder 422 is horizontally slidable and connected to the second connecting block. One side of the second connecting block is connected to the output end of the second horizontal push rod 423. The second horizontal push rod 423 drives the second connecting block to move horizontally. The housing of the second horizontal push rod 423 is connected to the cutting machine frame 1 through connecting bolts.

[0065] In this embodiment, by using a first horizontal push rod 413 to drive the first connecting block to move horizontally, the first connecting block drives the first sliding cylinder 412 to move horizontally together, and simultaneously by controlling a second horizontal push rod 423 to drive the second connecting block to move horizontally, the second connecting block drives the second sliding cylinder 422 to move horizontally together; thereby achieving the synchronous horizontal movement of the first guide limiting sleeve 411 and the second guide limiting sleeve 421, thus facilitating the smooth passage of the empty pipe through the first guide limiting sleeve 411 and the second guide limiting sleeve 421. Furthermore, the gap distance between the first conveying guide cylinder 41 and the second conveying guide cylinder 42 can be adjusted as needed to ensure the "limit" of force when passing through the first conveying guide cylinder 41 and the second conveying guide cylinder 42, avoiding the possibility of the empty pipe rupture or even breakage.

[0066] Furthermore, the conveying mechanism also includes a power structure, which is located on the side of the second conveying guide cylinder 42 away from the first guide limiting sleeve 411. The power structure includes a rotating conveyor seat 43, one end of which is rotatably connected to a connecting seat 431 via a rotating shaft. The connecting seat 431 is mounted on the cutting machine frame 1. The other end of the rotating conveyor seat 43 is connected to a rotating seat 432. A power shaft is connected to the end of the rotating seat 432 away from the rotating conveyor seat 43. The other end of the power shaft rotatably passes through a connecting plate 44 via a bearing, and a power transmission wheel 45 is connected to its end. The connecting plate 44 is used for mounting on the cutting machine frame 1. The power transmission wheel 45 is connected to a power drive wheel 46 via a belt drive. The drive wheel 46 is connected to a drive shaft. The other end of the drive shaft rotatably passes through the connecting plate via a bearing and is connected to the output end of the drive servo motor 47. The housing of the drive servo motor 47 is fixed to the connecting plate 44 with bolts. The connecting plate 44 has a channel for the passage of an empty tube. The empty tube passes through the conveying mechanism, that is, through the first guide limit sleeve 411 and the second guide limit sleeve 421, and then through the channel in the connecting plate 44. Under the action of the rotational pulling force of the rotating conveying seat 43 (the empty tube is wrapped around the rotating conveying seat 43, and the rotation of the rotating conveying seat 43 pulls the empty tube through the conveying mechanism, providing power for the movement of the empty tube), it passes through the channel in the connecting plate 44 and reaches and passes through the straightening mechanism.

[0067] Example 3

[0068] The straightening mechanism includes a straightening limiting gripper; the straightening limiting gripper is installed and connected to the output end of the finger cylinder 51, and the finger cylinder 51 drives the straightening limiting gripper to move; the top of the finger cylinder 51 is connected to a finger cylinder rotation cylinder 52, and the finger cylinder 51 is rotated by the finger cylinder rotation cylinder 52; the top of the finger cylinder rotation cylinder 52 is connected to a hydraulic telescopic rod 521 for driving the finger cylinder rotation cylinder 52 to move up and down; the other end of the hydraulic telescopic rod 521 is connected to an electric guide rail for driving the hydraulic telescopic rod 521 to move horizontally; the hydraulic telescopic rod 521 is horizontally movable with the top of the cutting frame 1 through the electric guide rail.

[0069] Meanwhile, the straightening mechanism also includes a movable guide structure, which is located on one side of the finger cylinder 51. The movable guide structure includes a movable guide hose 53; a first movable slider 531 is provided at the end of the movable guide hose 53 away from the finger cylinder 51, and one end of the movable guide hose 53 passes through the first movable slider 531. The first movable slider 531 is horizontally slidably mounted on the movable guide beam 54, and the movable guide beam 54 is connected to the cutting machine frame 1 through a fixed mounting plate; a guide block 532 is provided at the other end of the movable guide hose 53. The movable guide hose 53 passes through the guide block 532, and a connecting block is connected to the guide block 532. The connecting block is connected to the second movable slider 55 via a guide rail. The second movable slider 55 is connected to the movable guide beam 54 and can slide horizontally. A movable cylinder 551 is connected to the top of the second movable slider 55. The output end of the movable cylinder 551 is connected to the connecting block. The movable cylinder 551 drives the connecting block to move up and down along the second movable slider 55. The cylinder body of the movable cylinder 551 is fixed to the top of the second movable slider 55 by bolts.

[0070] Furthermore, a guide receiving block 541 is provided at one end of the movable guide hose 53 near the first movable slider 531. The guide receiving block 541 is connected to the movable guide beam 54. The guide receiving block 541 has a guide hole for the empty tube to pass through. The guide hole is coaxially arranged with the end of the movable guide hose 53 near the first movable slider 531. An intermediate transmission mounting plate is provided at the end of the guide receiving block 541 away from the first movable slider 531, and the intermediate transmission mounting plate is mounted on the movable guide beam 54; an intermediate guide limiting block 561 is connected to the end of the intermediate transmission mounting plate near the guide receiving block 541, and the intermediate guide limiting block 561 has a guide channel for the empty tube to pass through, and the guide channel is coaxially arranged with the guide hole opened in the guide receiving block 541; several intermediate transfer rollers 562 for rotating and driving the empty tube to pass through are mounted on the end of the intermediate guide limiting block 561 away from the guide receiving block 541 via a rotating shaft; the empty tube passes through the conveying mechanism, sequentially through the guide channel of the intermediate transfer rollers 562 and the intermediate guide limiting block 561. The tube passes through the guide hole in the guide receiving block 541, then enters the movable guide hose 53 through the first movable slider 531, passes through the guide block 532 at the other end of the movable guide hose 53, enters the finger cylinder 51, and passes between the straightening limiting claws installed on the finger cylinder 51. By adjusting the position of the finger cylinder 51, and then controlling the straightening limiting claws to "movably" limit and clamp the tube passing through, it plays a straightening and guiding role. This ensures that when the tube reaches the first cutting take-up rod 21 and the second cutting take-up rod 22 of the cutting mechanism and is wound into a loop, it is in a taut state, thus ensuring the required length and quality of the cut during cutting.

[0071] If the conveying power is insufficient, the finger cylinder 51 is controlled to drive the straightening limit gripper to assist in clamping and moving the empty tube, and to straighten the empty tube. After the empty tube is straightened, it is released, and then the empty tube is pulled by the pulling force of the first cutting take-up rod 21 and the second cutting take-up rod 22 "winding into a circle" in the cutting mechanism. Finally, the cutting cylinder 23 is controlled to move, and the empty tube that is wound into a circle by the first cutting take-up rod 21 and the second cutting take-up rod 22 is cut into segments in one go, so that it falls into the empty tube collection tray 2 for unified collection and further processing.

[0072] This cutting device uses mechanical automation to cut empty tubes into segments. It can effectively improve the efficiency of cutting and processing, reduce labor costs, and ensure the quality requirements of cutting.
