Description

Technical Field

[0001] This invention belongs to the field of winding equipment, specifically the winding equipment for SZ stranding production lines. Background Technology

[0002] With the popularization of fiber optic communication, optical cables are also widely used as transmission components for communication signals. There are many types of optical cables, among which stranded optical cables have better transmission performance compared with other optical cables. Stranded optical cables are manufactured by a layer-stranded optical cable forming machine. Regarding the direction of stranding, there are currently two types: one is left-hand, resembling an "S" and also called S-direction; the other is right-hand, resembling a "Z" and also called Z-direction. Therefore, SZ stranding can also be called left-right stranding. SZ stranding is an important part of the layer-stranded optical cable forming machine and is the core of the entire cable forming production line, directly affecting the production line speed and optical cable performance.

[0003] Existing stranding equipment for SZ strands uses two parallel concentric winding mechanisms to wind the stranded optical cable during the winding process. This results in a long distance between the first and second winding after stranding, causing severe backlash of the winding yarn, which in turn leads to loose stranded optical cable and greatly affects the performance of the optical cable.

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0055] refer to Figures 1 to 4 As shown, the stranding equipment of the SZ joint production line includes:

[0056] The twisting assembly 20 includes a twisting component 21 and a driving component 22 that drives the twisting component 21 to rotate back and forth. The twisting component 21 is provided with a plurality of circumferentially distributed core material channels 23, which are arranged along the length of the twisting component 21.

[0057] The wrapping assembly 10 has two sets, namely wrapping assembly one and wrapping assembly two, which are set back to back. The stranding component 21 is rotatably installed inside the wrapping assembly one. The core material channel 23 outlet is located at the end of the wrapping assembly one away from the stranding component 20. The wrapping assembly one immediately wraps the stranded core material once, and the wrapping assembly two immediately wraps the core material after the first wrapping.

[0058] Multiple core materials enter from their respective core material channels 23. The drive unit 22 (servo motor) drives the twisting unit 21 to reciprocate, rotating the multiple core materials by a certain angle. When the core materials reciprocate at the outlet, since the two wrapping components are set back to back, the core materials will be wrapped once by the yarn on the first wrapping component. The yarn on the second wrapping component will wrap the core materials after the first wrapping a second time. That is, the twisting position and the two wrapping points are almost at the same location. This allows the yarn that is wrapped twice to be wrapped when the twisting core material direction changes.

[0059] In the stranding equipment of the SZ stranding production line, a support frame 24 is rotatably mounted on the end of the stranding member 21 away from the wrapping assembly. The driving member 22 is mounted on the support frame 24 and connected to the stranding member 21 via belt drive. The support frame 24 supports the free end and also serves as the mounting fulcrum for the driving member 22, which facilitates a stable structural layout.

[0060] In the stranding equipment of the SZ joint production line, such as Figures 4 to 15 The wrapping assembly 10 includes:

[0061] The rotating spindle 11 has a core material passage area for the core material to pass through and an internal channel 13 for the packaging material to pass through.

[0062] The rotary motor assembly 12 and the rotary spindle 11 form a transmission connection, driving the rotary spindle 11 to rotate.

[0063] Packaging material release element 14 is distributed on the outside of the rotating spindle 11;

[0064] Release motor assembly 15, which forms a transmission connection with packaging material release component 14, and drives packaging material release component 14 to release the packaging material.

[0065] The tension adjustment structure 30 is located on the outer side of one end of the rotating spindle 11. The packaging material is led out through the built-in channel 13 and the tension of the packaging material is adjusted online through the tension adjustment structure 30.

[0066] The rotary motor unit 12 independently drives the rotary spindle 11 to rotate, tightly wrapping the packaging material around the surface of the core material. When the position of the tension adjustment structure 30 changes, the system will coordinate to control the release motor unit 15 to independently drive the packaging material release component 14 to release the packaging material, realizing fast and slow release of the packaging material, and preventing the packaging material from being over-tensioned and breaking or being stretched and thinned.

[0067] like Figure 11 , 12 As shown in Figures 14 and 15, the tension adjustment structure 30 includes:

[0068] Support base 31, which is rotatably fitted with rotating spindle 11;

[0069] Floating disk 32 is mounted on the outer wall of rotating spindle 11;

[0070] An adjustment frame 33 is provided, and an installation chamber 34 is provided inside the adjustment frame 33 for the floating disk 32 to rotate. Two sets of magnetic groups 36 are provided inside the installation chamber 34, and a second set of magnetic groups 35 is provided on the floating disk 32.

[0071] Tension adjusting cylinder 37 is mounted on support base 31 and its piston rod is connected to floating plate 32;

[0072] The movable tensioning wheel assembly 38 is slidably fitted on the outer wall of the rotating main shaft 11 along the axial direction of the rotating main shaft 11, and is connected to the floating disk 32 through the connecting rod 383.

[0073] The movable tensioning wheel assembly 38 includes a guide plate 381, on which a linkage disc 382 is slidably fitted. The linkage disc 382 and the floating disc 32 are connected by a connecting rod 383. A movable wheel 385 and a tensioning wheel 384 are mounted on the linkage disc 382. A wrapping wheel 386 and a winding wheel 387 are mounted on the end of the guide plate 381 away from the floating disc 32. The linkage disc 382 is provided with a slot through which the guide plate 381 passes. A groove is provided on the side of the slot near the rotating main shaft 11. Mounting plates on both sides of the tensioning wheel 384 are installed in the groove. After the two ends of the guide plate 381 are connected to the rotating main shaft 11, the tensioning wheel 384 is constrained from detaching from the groove and the slot by the restriction of the guide plate 381.

[0074] The packaging material is led out through the built-in channel 13 of the rotating spindle 11 and wound around the surface of the core material via the winding wheel 387, tensioning wheel 384, and wrapping wheel 386.

[0075] A fixing rod 39 is installed on the support base 31, and a connecting block 310 is slidably fitted on the fixing rod 39. The connecting block 310 is installed on the adjusting frame 33.

[0076] like Figure 6 As shown, the adjusting frame 33 includes a first annular disc 331 and a second annular disc 332. An outer sealing ring 333 is provided between the first annular disc 331 and the second annular disc 332. Magnetic assemblies 36 are installed between the facing sides of the first annular disc 331 and the second annular disc 332, and are distributed in a circumferential manner at equal intervals. The two ends of the outer sealing ring 333 are connected to the first annular disc 331 and the second annular disc 332 by bolts, facilitating the installation of the floating disc 32.

[0077] like Figure 8 , 9 As shown in Figures 10 and 13, in the stranding equipment of the SZ stranding production line, the packaging material release component 14 includes:

[0078] Mounting plate 141 is mounted on the outside of the rotating spindle 11;

[0079] A pulley 142 is rotatably mounted on the outside of the rotating main shaft 11;

[0080] Packaging material roller 143 is rotatably mounted on the outside of the rotating main shaft 11;

[0081] Transmission component 144 is rotatably mounted on mounting plate 141 and its two ends are respectively connected to pulley plate 142 and packaging material roller 143.

[0082] The transmission component 144 is provided with transmission gears 145 at both ends;

[0083] A transmission disc 146 is provided at one end of the pulley 142 and the packaging roller 143 facing the mounting disc 141. The inner wall of the transmission disc 146 is provided with a transmission gear structure for meshing with the transmission gear 145.

[0084] The mounting plate 141 is provided with a through hole 147 for the packaging material to pass through;

[0085] The mounting plate 141 is provided with a picking wheel 148, a packaging material passage groove 149 and a pressing roller group 151 on the side facing the pulley plate 142. A sealing plate 150 is installed at the opening of the packaging material passage groove 149. The sealing plate 150 is provided with a packaging material inlet. The packaging material passes through the through hole 147, the picking wheel 148 and is pressed by the pressing roller group 151 onto the transmission plate 146, and then enters the built-in channel 13 through the packaging material inlet and the packaging material passage groove 149.

[0086] The packaging material is released synchronously by the packaging material roller 143 as the rotating spindle 11 rotates. The released packaging material is suspended by the pick-up wheel 148 through the through hole 147 and guided between the outer wall of the pressure roller group 151 and the corresponding transmission disk 146. The pressure roller group 151 includes two sets of rollers and a pressure belt fitted on the outside of the rollers. The pressure belt tightly adheres the packaging material to the outside of the transmission disk 146. After passing through the pressure belt, the packaging material enters the packaging material inlet and the packaging material through the through groove 149 and enters the built-in channel 13. Finally, it is introduced from the end of the rotating spindle 11 and then wrapped around the core material in sequence through the winding wheel 387, tension wheel 384, and wrapping wheel 386.

[0087] During actual wrapping, the core material passes through the core material passage area and then through the rotating spindle 11. The wrapping material is guided into the built-in channel 13 and led out from the end of the rotating spindle 11. It is then led out through the winding wheel 387, tension wheel 384, and wrapping wheel 386. Under the action of the rotating motor assembly 12, the rotating spindle 11 wraps the wrapping material around the surface of the core material. A position sensor (which can be installed on the support base 31) is independently installed on one side of the axial direction of the adjusting frame 33. The position sensor is used to detect the position change of the adjusting frame 33 and to determine the tension of the wrapping material based on the position change. The system automatically controls the release motor assembly 15 to rotate via the belt drive connected to the pulley 142. The pulley 142 drives the two transmission discs 146 to rotate, actively accelerating or decelerating the release of the wrapping material, thereby achieving constant tension wrapping. Here, constant tension refers to a certain tension range set, not a specific tension value.

[0088] When the tension increases, the packaging material will drive the linkage plate 382 to approach the end of the rotating main shaft 11, and via the connecting rod 383, drive the floating plate 32 to approach the support base 31. Since the floating plate 32 and the adjusting frame 33 are connected by non-contact (magnetic repulsion), the adjusting frame 33 and the connecting block 310 will approach the support base 31 along the length direction of the fixed rod 39. The position sensor will detect the position change, and the system will release the motor group 15 to accelerate the rotation of the belt drive connected to the pulley 142, and adjust the position of the adjusting frame 33 in the opposite direction until it returns to the set position, thus automatically reducing the tension.

[0089] When the tension decreases, the force exerted by the packaging material on the tensioning wheel 384 decreases, and the linkage disc 382 moves away from the end of the rotating main shaft 11. Through the connecting rod 383, the floating disc 32 moves away from the support seat 31. Since the floating disc 32 and the adjusting frame 33 are connected by non-contact (magnetic repulsion), the adjusting frame 33 and the connecting block 310 move away from the support seat 31 along the length of the fixed rod 39. The position sensor detects the position change and releases the motor unit 15 to decelerate the pulley 142 via belt drive, adjusting the position of the adjusting frame 33 in the opposite direction until it returns to the set position, thus automatically increasing the tension and finally completing the constant tension wrapping operation.

[0090] During the actual SZ stranding process, multiple optical fiber cores enter from the corresponding core material channel 23 and exit from the end of the core material channel 23. As the driving component 22 drives the multiple cores to rotate back and forth at a certain angle, the yarn on the wrapping assembly one immediately wraps the multiple cores exiting from the core material channel 23. At the same time, the yarn on the wrapping assembly two immediately wraps the cores after the first wrapping. The yarn that was wrapped once is immediately fixed to prevent the yarn that was wrapped once from backing up when the core material direction is switched, which would make the wrapped state of the multiple cores loose. Once loose, it will affect the performance of the optical cable. Therefore, by bringing the stranding position and the two wrapping positions together, the performance of the optical cable can be guaranteed.

[0091] During the wrapping process, the packaging material (yarn) is pressed against the outer wall of the transmission disc 146 by the clamping belt through the through hole 147 and the pick-up wheel 148. The packaging material is then guided from the packaging material inlet into the packaging material through slot 149 by another guide wheel on the mounting disc 141, and then introduced into the built-in channel 13 inside the rotating spindle 11. After being led out from the end, it is guided by the winding wheel 387, tension wheel 384, and wrapping wheel 386. As the rotating spindle 11 rotates under the action of the rotating motor group 12, the packaging material is tightly wrapped around the core material.

[0092] During the wrapping process, as the tension increases, the packaging material will drive the linkage disk 382 to approach the end of the rotating spindle 11, and via the connecting rod 383, drive the floating disk 32 to approach the support base 31. Since the floating disk 32 and the adjusting frame 33 are connected by non-contact (magnetic repulsion), the adjusting frame 33 and the connecting block 310 will approach the support base 31 along the length direction of the fixed rod 39. The position sensor will detect the position change, and the system will adjust the position of the adjusting frame 33 in the opposite direction through the tension adjusting cylinder 37 until it returns to the set position.

[0093] When the tension decreases, the force exerted by the packaging material on the tensioning wheel 384 decreases, and the linkage disc 382 moves away from the end of the rotating spindle 11. Through the connecting rod 383, the floating disc 32 moves away from the support seat 31. Since the floating disc 32 and the adjusting frame 33 are connected by non-contact (magnetic repulsion), the adjusting frame 33 and the connecting block 310 move away from the support seat 31 along the length of the fixed rod 39. The position sensor will detect the position change, and the system will adjust the position of the adjusting frame 33 in the opposite direction through the tension adjusting cylinder 37 until it returns to the set position, and finally complete the constant tension wrapping operation.

[0094] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
