Description

Technical Field

[0001] This invention relates to the field of optical cable manufacturing equipment technology, specifically to a paste spraying device and method for manufacturing B1-grade flame-retardant optical cables. Background Technology

[0002] As communication network construction continues to expand into diverse scenarios, optical cables, as the core carrier of signal transmission, are increasingly being used in environments beyond conventional indoor and outdoor settings, including special areas with extremely high fire safety requirements such as subway tunnels, high-rise buildings, and data center computer rooms. Besides the flame-retardant sheath and flame-retardant filler rope, the core structure of B1-grade flame-retardant optical cables hinges on the grease filling and spraying process within the cable core. The grease not only needs to possess B1-grade flame-retardant properties matching the overall optical cable performance, but also needs to be evenly sprayed onto the surface of the fiber bundle and fill the gaps between the cable cores to achieve waterproofing, moisture resistance, cushioning against compression, and isolation of the optical fiber from external corrosive environments, directly impacting the transmission stability and service life of the optical cable.

[0003] Chinese Patent CN110918291B, authorized and published on May 28, 2021, discloses an optical cable grease spraying device, which includes a support plate, a fixed plate, a feeding assembly, a discharging assembly, a rotating assembly, a spraying assembly, a grease supply assembly, and a heating assembly. The support plate is set on the ground, and the fixed plate is set on the support plate.

[0004] In the aforementioned application, a rotating disk in a reciprocating state is used to drive the paste storage cylinder and the spray head mounted on the rotating disk to reciprocate together, so that it can perform spraying operations on various parts of the outer ring of the optical cable. However, during the spraying process using the spray head, the spray head rotates with the paste storage cylinder, and the sprayed paste is in a single arc state, which makes the device less efficient in covering various positions of the outer ring of the optical cable.

[0020] 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.

[0021] Example 1, please refer to Figures 1-4 A grease spraying device and method for manufacturing B1-grade flame-retardant optical cables, comprising: Spraying chamber 100, the interior of which is fitted with fasteners 200; An electric turntable 300 is mounted on the side of a fixing component 200. A paste storage cylinder 400 is mounted on the side of the electric turntable 300. A collection box 500 is mounted inside the spraying chamber 100. A heating chamber 600 is mounted on the side of the fixing component 200. A fixing plate 701 is mounted on the side of the electric turntable 300. A rotating rod 702 and a rotating rod 703 are rotatably connected to the outside of the fixing plate 701. A gear 704 is fixedly connected to the side of the rotating rod 702. The optical cable to be coated with the grease is fed into the spraying chamber 100 through the conveying mechanism. The booster pump and the electric turntable 300 are activated to feed the grease into the grease storage cylinder 400. The electric turntable 300, which is in a reciprocating rotation state, drives the grease storage cylinder 400 and the fixing plate 701 mounted on its side to rotate together, so that the gear 704 mounted on the fixing plate 701 through the rotating rod 702 rotates together with the fixing plate 701.

[0022] A gear ring 705 is fixedly connected to the side of the fixing component 200. A connector 710 is rotatably connected to the bottom of the paste storage cylinder 400. A transmission component for transmission is assembled between the rotating rod 702 and the connector 710. The transmission component includes a bevel gear 706 assembled on the outside of the rotating rod 702. A bevel gear 707 and a sprocket 708 are fixedly connected to the outside of the rotating rod 703. The bevel gear 707 is located on the side of the bevel gear 706 and is meshed with the bevel gear 706. A chain 709 is assembled on the outside of the sprocket 708. A sprocket 711 is fixedly connected to the outside of the connector 710. The end of the chain 709 away from the sprocket 708 is assembled on the outside of the sprocket 711. A spray head 712 is assembled at the bottom of the connector 710. When gear 704 revolves, it is constrained by the gear ring 705 meshing with it, causing gear 704 to reciprocate synchronously. This drives the rotating rod 702, which is fixedly connected to gear 704, to rotate. The rotating rod 702 then drives the bevel gear 706, which is fixedly connected to it, to rotate. The bevel gear 706 then drives the bevel gear 707, which meshes with it, to rotate. The bevel gear 707 then drives the rotating rod 703, which is fixedly connected to it, to rotate. The rotating rod 703 then drives the sprocket 708, which is fixedly connected to it, to rotate back and forth. This, along with the chain 709 mounted on the outside of the sprocket 708, causes the sprocket 711, which is connected to the sprocket 708 via the chain 709, to rotate back and forth as well. The sprocket 711 then drives the connector 710, which is fixedly connected to it, to rotate back and forth. This causes the spray head 712, which is mounted at the bottom of the connector 710, to rotate back and forth. In this way, the spray head 712 can rotate synchronously while spraying around the outer ring of the optical cable, thereby increasing the coverage of the grease and improving the spraying efficiency of the device.

[0023] In use, the optical fiber to be coated with the grease is fed into the spraying chamber 100 via the conveying mechanism. The booster pump and electric turntable 300 are activated to deliver the grease into the storage cylinder 400. The reciprocating electric turntable 300 drives the storage cylinder 400 and the fixing plate 701 mounted on its side to rotate together. This causes the gear 704, mounted on the fixing plate 701 via the rotating rod 702, to rotate along with the fixing plate 701. During its revolution, the gear 704 is constrained by the gear ring 705 it meshes with, causing the gear 704 to reciprocate synchronously, driving the rotating rod 702, which is fixedly connected to the gear 704, to rotate. The rotating rod 702 drives the bevel gear 706, which is fixedly connected to it, to rotate. The bevel gear 706 then drives the bevel gear 707, which meshes with it, to rotate. This causes the rotating rod 703, which is fixedly connected to it, to rotate. The rotating rod 703 drives the sprocket 708, which is fixedly connected to it, to rotate back and forth. The chain 709, which is mounted on the outside of the sprocket 708, causes the sprocket 711, which is connected to the sprocket 708 via the chain 709, to rotate back and forth as well. The sprocket 711 drives the connector 710, which is fixedly connected to it, to rotate back and forth, causing the spray head 712, which is mounted on the bottom of the connector 710, to rotate back and forth.

[0024] Example 2, please refer to Figures 1-6 Based on Embodiment 1, the interior of the spraying chamber 100 is equipped with an auxiliary collection component 800 for collecting excess grease. The auxiliary collection component 800 includes a rotating rod 801 rotatably connected to the side of the fixing member 200, a power gear ring 810 fixedly connected to the outside of the electric turntable 300, a gear 802 fixedly connected to one side of the rotating rod 801, a bevel gear 803 fixedly connected to the other side of the rotating rod 801, a lead screw 804 rotatably connected inside the spraying chamber 100, a bevel gear 805 fixedly connected to the side of the lead screw 804, the bevel gear 805 being located on the side of the bevel gear 803 and meshing with the bevel gear 803. Excess grease dripping from the optical cable is collected in the collection box 500 located at the bottom of the spray head 712 and discharged by the inclined plate inside the collection box 500. When the electric turntable 300 reciprocates, it drives the power gear ring 810 fixedly connected to it to reciprocate, which in turn drives the gear 802 meshing with it to rotate. The gear 802 in the reciprocating state drives the rotating rod 801 fixedly connected to it to rotate, which in turn drives the bevel gear 803 fixedly connected to it to rotate. The bevel gear 803 then drives the bevel gear 805 meshing with it to rotate, which in turn drives the lead screw 804 fixedly connected to it to reciprocate.

[0025] A sliding plate 806 is threadedly connected to the outer side of the lead screw 804. The sliding plate 806 is located inside the spray chamber 100 and is slidably connected to the spray chamber 100. A connecting plate 808 is connected to the top of the sliding plate 806 via a spring 807, and a brush rod 809 is mounted on the bottom of the connecting plate 808. When the lead screw 804 reciprocates, the sliding plate 806, threaded onto the lead screw 804, is simultaneously constrained by the spray chamber 100 to which it is slidably connected. This causes the sliding plate 806 to reciprocate horizontally during the reciprocating rotation of the lead screw 804, driving the spring 807, connecting plate 808, and brush rod 809 mounted on the sliding plate 806 to move synchronously. Under the action of the spring 807, the brush rod 809 scrapes off residual grease on the inclined plate inside the collection box 500 during its movement, improving the collection efficiency of the collection box 500.

[0026] In use, based on Example 1, excess grease dripping from the optical cable is collected by the collection box 500 located at the bottom of the spray head 712 and discharged under the action of the inclined plate inside the collection box 500. When the electric turntable 300 reciprocates, it drives the power gear ring 810 fixedly connected to it to reciprocate, causing the power gear ring 810 to drive the gear 2 802 meshing with it to rotate. The gear 2 802 in the reciprocating state drives the rotating rod 3 801 fixedly connected to it to rotate, causing the rotating rod 3 801 to drive the bevel gear 3 803 fixedly connected to it to rotate. The bevel gear 3 803 then drives... The bevel gear 805 meshing with it rotates, causing the bevel gear 805 to drive the lead screw 804 fixedly connected to it to reciprocate. The sliding plate 806, which is threadedly mounted on the lead screw 804, is simultaneously restricted by the spraying chamber 100 slidably connected to it. As the lead screw 804 reciprocates, the sliding plate 806 moves reciprocally in the horizontal direction, causing the spring 807, connecting plate 808 and brush rod 809 mounted on the sliding plate 806 to move synchronously. Under the action of the spring 807, the brush rod 809 scrapes off the residual grease on the inclined plate inside the collection box 500 during the movement.

[0027] Example 3, please refer to Figures 1-7Based on Embodiment 1 and Embodiment 2, the heating chamber 600 is equipped with an auxiliary air guiding component 900 for guiding hot air. The auxiliary air guiding component 900 includes a hot air duct 901 that passes through the heating chamber 600. A cam 903 is mounted on the outside of the rotating rod 801. A hydraulic chamber 902 is mounted on the side of the fixing member 200. One end of the hydraulic chamber 902 is slidably connected to a force rod 904 by a piston. The force rod 904 is located on the side of the cam 903 and is in contact with the cam 903. When the rotating rod 801 is in a reciprocating rotation state, the cam 903 mounted on the outside of the rotating rod 801 reciprocates along with it. When the protruding part of the cam 903 rotates to the force rod 904, it can squeeze the force rod 904 and drive the force rod 904 to move to the side a certain distance. In conjunction with the hydraulic chamber 902 which is slidably connected to the force rod 904 by a piston, the force rod 904 squeezes the oil originally stored in the hydraulic chamber 902 when it moves into the hydraulic chamber 902.

[0028] The other end of the hydraulic chamber 902 is connected to an arc rod 905 via a piston. The bottom of the hot air duct 901 is rotatably connected to a connector 906. A torsion spring rod 907 is fixedly connected to the side of the connector 906. A force plate 908 is fixedly connected to the outside of the torsion spring rod 907. A nozzle 909 is fitted at the bottom of the connector 906. When the oil originally stored in the hydraulic chamber 902 is squeezed, the oil flows towards the side closer to the arc-shaped rod 905, causing the arc-shaped rod 905, which is slidably connected to the hydraulic chamber 902, to extend out of the hydraulic chamber 902. The arc-shaped rod 905 can then squeeze the force plate 908 and cause the force plate 908 to move, causing the force plate 908 to drive the torsion spring rod 907, which is fixedly connected to it, to rotate at a certain angle. When the cam 903 continues to rotate and moves away from the force plate 904, the cam 903 immediately loses the restriction of the force plate 904. Similarly, the arc-shaped rod 905 and the force plate 908 lose their restriction and can rotate in the opposite direction under the action of the torsion spring rod 907 to reset. In this way, the torsion spring rod 907 can rotate back and forth, causing the second connector 906 to rotate back and forth, causing the second connector 906 to drive the nozzle 909 assembled at its bottom to rotate back and forth synchronously, repeatedly blowing the hot air sent in through the hot air pipe 901 onto the optical cable that has been sprayed with grease, improving the efficiency of the device's heating and solidification.

[0029] In use, based on Embodiments 1 and 2, when the rotating rod 801 is in a reciprocating rotation state, the cam 903 mounted on the outside of the rotating rod 801 reciprocates along with it. When the protruding part of the cam 903 rotates to the force rod 904, it can squeeze the force rod 904 and drive the force rod 904 to move to the side a certain distance. In conjunction with the hydraulic chamber 902 which is slidably connected to the force rod 904 by a piston, when the force rod 904 moves into the hydraulic chamber 902, it squeezes the oil originally stored in the hydraulic chamber 902. The oil then flows towards the side closer to the arc-shaped rod 905, causing the arc-shaped rod 905, which is slidably connected to the hydraulic chamber 902, to extend out of the hydraulic chamber 902. 05 can squeeze the force plate 908 and drive the force plate 908 to move, so that the force plate 908 drives the torsion spring rod 907 fixedly connected to it to rotate at a certain angle. When the cam 903 continues to rotate and moves away from the force rod 904, the cam 903 will lose the restriction of the force rod 904. Similarly, the arc rod 905 and the force plate 908 lose their restriction and can rotate in the opposite direction under the action of the torsion spring rod 907 to reset. In this way, the torsion spring rod 907 can rotate back and forth, driving the second connector 906 to rotate back and forth, so that the second connector 906 drives the nozzle 909 assembled at its bottom to rotate back and forth synchronously, blowing the hot air sent through the hot air pipe 901 repeatedly onto the optical cable that has been sprayed with grease, heating and solidifying it.
