Description

Technical Field

[0001] The invention belongs to the technical field of optical cable production and manufacturing, and specifically relates to an optical cable grease high-speed automatic coating device and coating method. Background Art

[0002] Optical cable water blocking refers to a series of measures to prevent moisture from entering the interior of the optical cable, which is crucial to the performance and service life of the optical cable. Moisture entering the interior of the optical cable may cause increased optical fiber attenuation and affect the transmission quality of the signal. When water enters the interior of the optical cable, it will interact with the glass material in the optical fiber, resulting in microbend loss, causing the optical signal to be scattered and absorbed during transmission, reducing the signal strength; and long-term water erosion of the optical cable may also damage the metal components in the optical cable, such as the reinforcing core and armor layer, which will lead to a decrease in the mechanical properties of the optical cable and even cause the optical cable to break. Therefore, optical cable water blocking is particularly important for the production and use of optical cables.

[0003] Existing optical cable water-blocking methods are mainly divided into two forms: dry water-blocking and grease water-blocking. Dry water-blocking mainly adopts water-blocking powder, water-blocking yarn or water-blocking tape, and water-blocking is achieved by adding a water-blocking structure inside the optical cable; grease water-blocking mainly coats the inside of the optical cable with water-blocking paste, which fills the internal gaps of the optical cable. When moisture enters from the outside, the water-blocking paste will absorb water and expand to block the interface of the optical cable where the water-blocking paste is located, preventing external moisture from continuing to enter the interior of the optical cable, thereby achieving a good water-blocking effect.

[0004] The water-blocking paste is mainly filled with cable core paste and sprayed on the metal belt surface. The metal belt spray paste mainly uses a solenoid valve spray device to control the paste spraying length and spacing. As the production rate of optical cables gradually increases, the spraying rate of the solenoid valve spray device also needs to be gradually increased. When the production rate continues to increase, the opening and closing frequency of the solenoid valve reaches the upper limit, resulting in frequent problems such as paste blockage and valve wear in the spray device, which affects the production quality of the optical cable and makes it difficult to increase the production efficiency of the optical cable.

[0049] Example:

[0050] See also Figures 1 to 6 The optical cable jelly high-speed automatic coating device in the preferred embodiment of the present invention includes a first spraying mechanism, which includes a mounting shell 1, a connecting hole 2 is provided at the side wall of the mounting shell 1, and the connecting hole 2 is used to connect with the jelly container to inject the jelly into the mounting shell 1; a spraying chamber 3 is also rotatably provided in the mounting shell 1, and the spraying chamber 3 is connected with a spraying port 11. At the same time, at least one docking hole 4 is provided on the side wall of the spraying chamber 3, and the docking hole 4 and the connecting hole 2 are arranged in the same radial plane of the spraying chamber 3, and the docking hole 4 and the connecting hole 2 can be rotatably connected, so that the jelly container and the spraying chamber 3 are intermittently connected; at the same time, the spraying chamber 3 is also connected with a driving mechanism 5, and the driving mechanism 5 is used to drive the spraying chamber 3 to rotate with the axial direction as the center, so that the docking hole 4 and the connecting hole 2 are matched in rotation; the mounting shell 1 is also connected with a mounting plate 6, and the mounting plate 6 is connected with a displacement mechanism, and the displacement mechanism is used to drive the mounting plate 6 to displace in at least two directions.

[0051] Specifically, the optical cable jelly high-speed automatic coating device in the present application changes the traditional electromagnetic valve spraying method, by setting the spray chamber 3 and the mounting shell 1 in a rotation matching form, and using the driving mechanism 5 to drive the spray chamber 3 to rotate, the spraying rate of the spray chamber 3 depends on the rotation rate of the driving mechanism 5, when the docking hole 4 and the connecting hole 2 are rotationally matched, the jelly in the jelly container can be sprayed out through the spray chamber 3, which solves the problem that the traditional coating device relies on the on-off frequency of the electromagnetic valve, and greatly improves the spraying frequency of the coating device. Secondly, the present application sets a mounting plate 6 and a displacement mechanism, so that the spray port 11 of the spray chamber 3 can be moved according to the spraying point of the cable core 15, thereby realizing the adjustable jelly spraying point, realizing the intelligent adjustment of the jelly spraying point, so as to further improve the production efficiency of the optical cable. Optionally, a coupling 14 can also be set between the driving mechanism 5 and the rotating shaft, and the coupling 14 can ensure that the rotational force of the driving mechanism 5 is stably transmitted to the spray chamber 3.

[0052] Optionally, the spray chamber 3 in the present application is provided with a plurality of docking holes 4 on the same radial plane. When the spray chamber 3 rotates, at least one of the docking holes 4 will match the connecting hole 2, so that the grease enters the spray chamber 3 and is then sprayed out from the spray port 11. The form of multiple docking holes 4 increases the matching rate of the docking holes 4 and the connecting hole 2, thereby increasing the spraying efficiency of the coating device. It is worth noting that at this time, the inner wall of the spray chamber 3 is in contact with the inner wall of the mounting shell 1, so that when one of the docking holes 4 matches the connecting hole 2, the other docking holes 4 are closed by the inner wall of the mounting shell 1, thereby avoiding leakage of the grease and ensuring the spraying rate of the coating device.

[0053] Further, as an optional embodiment of the present invention, a first connection hole 7 is provided on the mounting plate 6 in the present application, the spraying mechanism is arranged on one side of the mounting plate 6, the driving mechanism 5 is arranged on the other side of the mounting plate 6, and the rotating shaft of the driving mechanism 5 passes through the first connection hole 7 and is connected to the spraying mechanism. The mounting plate 6 serves as a connection carrier of the first spraying mechanism, so that the first spraying mechanism and the driving mechanism 5 can be relatively fixed, and then the mounting plate 6 is fixed to the optical cable production equipment through the displacement mechanism, which is convenient for adjusting the spraying port 11 and facilitating the stable operation of the optical cable oil jelly high-speed automatic coating device.

[0054] Further, as an optional embodiment of the present invention, the mounting shell 1 in the present application is arranged in a cylindrical shape, and a first sealing cover 8 is provided at one end of the mounting shell 1, and the first sealing cover 8 is attached to the mounting plate 6. A through hole for the rotation shaft to pass through is opened on the first sealing cover 8, and the rotation shaft passes through the first sealing cover 8 and is rotatably connected to the spray chamber 3. The spray chamber 3 is rotatably arranged in the mounting shell 1, and the mounting shell 1 is in a cylindrical structure to facilitate the matching of the two. Under the premise of equal size, the inner cavity size of the spray chamber 3 can be increased as much as possible to facilitate the high-speed spraying of the grease. The first sealing cover 8 is used to seal the side of the mounting shell 1 close to the mounting plate 6 to prevent the grease container from entering the mounting shell 1. At the same time, the first sealing cover 8 facilitates the setting of the rotating shaft, and the single first sealing cover 8 is easy to process, so that the rotating shaft and the first sealing cover 8 are tightly matched to prevent the grease from leaking from the through hole on the first sealing cover 8.

[0055] Furthermore, as an optional embodiment of the present invention, the spray chamber 3 in the present application is also cylindrical, and the outer wall of the spray chamber 3 is attached to the inner wall of the mounting shell 1; the spray chamber 3 and the inner wall of the mounting shell 1 are fitted together, so that after the ointment in the ointment container enters the mounting shell 1, it will not penetrate into the gap between the mounting shell 1 and the spray chamber 3, and when the docking hole 4 and the connecting hole 2 are misaligned, the connecting hole 2 is closed by the side wall of the spray chamber 3, which can make the ointment in the ointment container have a certain pressure. When the docking hole 4 and the connecting hole 2 are aligned, the ointment can be quickly sprayed into the spray chamber 3, which is convenient for the ointment at the spray port 11 to be sprayed out. Secondly, a connecting shaft 9 is provided at one end of the spray chamber 3 facing the first sealing cover 8, and the connecting shaft 9 matches the rotating shaft, so that the spray chamber 3 can rotate with the driving mechanism 5; a second sealing cover 10 is also provided at one end of the spray chamber 3 away from the first sealing cover 8, and the second sealing cover 10 is connected to the mounting housing 1, and a spraying port 11 is provided on the second sealing cover 10, and the spraying port 11 is connected to the spray chamber 3. The second sealing cover 10 is used to match the first sealing cover 8, close both ends of the mounting housing 1, and the spraying port 11 is provided on the second sealing cover 10, so that the ointment entering the spray chamber 3 can be sprayed out from the spraying port 11.

[0056] Further, as an optional embodiment of the present invention, the spray chamber 3 in the present application is arranged in a stepped shaft, and the outer wall of the spray chamber 3 where the docking hole 4 is arranged is attached to the inner wall surface of the mounting shell 1; the spray chamber 3 is provided with rotating bearings 12 on both sides of the docking hole 4, and the two rotating bearings 12 are sleeved in the mounting shell 1, and the two rotating bearings 12 are also provided with sealing gaskets 13 on the side away from the docking hole 4. In the present application, the outer diameter of the spray chamber 3 where the docking hole 4 is arranged is the largest, and the size of the docking hole 4 along the axial sides of the spray chamber 3 is reduced, so that the docking hole 4 is attached to the inner wall of the mounting shell 1. When the docking hole 4 is misaligned with the connecting hole 2, the outer wall of the spray chamber 3 can close the connecting hole 2 to prevent the grease from entering the installation gap between the mounting shell 1 and the spray chamber 3. The spray chamber 3 is in the form of a stepped shaft, so that rotating bearings 12 can be set on both sides of the docking hole 4. The rotating bearings 12 facilitate the high-speed rotation of the spray chamber 3 in cooperation with the driving mechanism 5 to achieve intermittent spraying of the grease, and the rotating bearings 12 facilitate the stable installation of the spray chamber 3 and the mounting housing 1, avoiding problems such as shaking or displacement during the rotation of the spray chamber 3. The sealing gasket 13 can prevent the grease entering the mounting housing 1 from overflowing from both sides. Preferably, the rotating bearings 12 on both sides of the docking hole 4 are ball bearings.

[0057] Further, as an optional embodiment of the present invention, the displacement mechanism in the present application includes a mounting seat, which is used to install the optical cable jelly high-speed automatic coating device on the optical cable production line, so as to facilitate the position adjustment of the spray port 11 and the stable operation of the coating device. A first slide rail is provided on the mounting seat, and a first slide seat is slidably matched on the first slide rail. The first slide rail is arranged vertically, so that the first slide seat can be lifted and lowered vertically; a second slide rail is also provided on the first slide seat, and a second slide seat is arranged on the second slide rail, and the mounting plate 6 is connected to the second slide seat, and the second slide seat is arranged horizontally, and the setting direction of the second slide seat is the same as the setting direction of the spray port 11, so that the second slide rail can drive the spray port 11 to move toward or away from the position of the cable core 15.

[0058] Further, as an optional embodiment of the present invention, the spray port 11 in the present application is threadedly connected with a nozzle 17, and an opening for spraying the oil paste is provided on the nozzle 17. A piston 18 is provided in the nozzle 17 along the width direction of the opening, and the piston 18 is connected to a screw structure, and the piston 18 can be driven to move along the width direction of the opening through the screw structure to adjust the opening width of the nozzle 17. The optical cable oil paste high-speed automatic coating device in the present application can adjust the oil paste spraying width in addition to the spraying rate and the position of the nozzle 17. Specifically, the present application sets a nozzle 17 at the spray port 11, and controls the movement of the piston 18 through the screw structure. When the spraying width needs to be adjusted, the piston 18 is driven to move by a servo cylinder or a servo motor, and the position control of the piston 18 intruding into the nozzle 17 is controlled to achieve the width size adjustment of the nozzle 17 to complete the adjustment of the oil paste spraying width.

[0059] Further, as an optional embodiment of the present invention, the mounting shell 1 in the present application is connected to the paste container through a connecting pipe, a paste pump is arranged in the paste container, and the paste is injected into the mounting shell 1 through the paste pump, and the connecting pipe and the mounting shell 1 are detachably connected, and the connecting pipe can be selected as a tube body with different inner diameters. The rotation rate of the driving mechanism 5 can only affect the spraying spacing of the paste on the steel belt 16, and cannot affect the length of the paste at a single coating point. When it is necessary to adjust the spraying length of the paste on the steel belt 16, the present application can control the amount of paste injected into the spray chamber 3 at a single time by selecting connecting pipes with different inner diameters, so as to adjust the coating length of the paste on the steel belt 16, thereby realizing the adjustment of the paste spraying length.

[0060] Further optionally, the size of the connection hole 2 on the mounting shell 1 in the present application is adjustable, the connection hole 2 can be provided with a sandwich structure, a slidable baffle structure is provided in the radial direction of the connection hole 2, and the baffle is controlled by a cylinder or a motor to move in the radial direction of the connection hole 2 to adjust the opening size of the connection hole 2, so as to adjust the length of the grease spraying. Optionally, the present application can set a clamping piece on the connection pipe, and adjust the inner hole size of the connection pipe by the clamping piece, which can also adjust the amount of grease injected into the spraying chamber 3, so as to complete the adjustment of the spraying length of the grease on the steel belt 16.

[0061] Further, as an optional embodiment of the present invention, the optical cable jelly high-speed automatic coating device in the present application also includes a visual detection component, the visual detection component is arranged toward the nozzle 17, and the visual detection component is mainly used to detect the amount of jelly sprayed at the nozzle 17; a second spraying mechanism, the second spraying mechanism is arranged side by side with the first spraying mechanism, and the second spraying mechanism is connected to the jelly container; and a control component, the control component is electrically connected to the visual detection component, the first spraying mechanism and the second spraying mechanism respectively, and the control component is used to control the first spraying mechanism or the spraying mechanism to spray the jelly, so as to realize the switching work of the first spraying mechanism and the second spraying mechanism. In order to ensure the efficient and stable production of the optical cable, the present application additionally sets the second spraying mechanism. When the visual detection component detects that the spraying flow rate of the first spraying mechanism is small, it means that the nozzle 17 is blocked; in order to ensure the normal operation of the optical cable production, the present application correspondingly sets the control component and the second spraying mechanism. When the first spraying mechanism is blocked, the control component switches to the second spraying mechanism to realize the jelly spraying.

[0062] Furthermore, the present application also includes a method for coating optical cable grease, which is coated by using the above-mentioned optical cable grease high-speed automatic coating device. Specifically, the method for coating optical cable grease includes the following steps:

[0063] Obtain the size of the cable core 15 and the size of the steel belt 16;

[0064] Obtain the initial positions of both ends of the steel belt 16 and the central axis position of the cable core 15, calculate the longitudinal coating length of the steel belt 16, calculate the amount of grease applied, and adjust the spraying rate and grease dosage settings according to the production requirements of the optical cable;

[0065] Move the nozzle 17 to the set position, adjust the position of the piston 18 according to the width of the metal strip, so that the grease spraying width meets the metal strip width spraying requirements; adjust the rotation frequency of the driving mechanism 5 so that the grease spraying rate meets the process setting requirements;

[0066] The optical cable grease high-speed automatic coating device works according to the set standards to complete the grease spraying.

[0067] Furthermore, in the present application, the calculation of the longitudinal wrapping length of the steel strip 16 specifically includes:

[0068] Obtain the initial positions A(x1, y1) and B(x2, y2) of the two ends of the steel belt 16, the central axis position O(x3, y3) of the cable core 15, set the two ends of the steel belt 16 to be at the same horizontal height, then y1=y2; the length of the steel belt 16 is x2-x1, and the outer peripheral size of the cable core 15 after the steel belt 16 is covered is 2π(y3-y1), then the overlap length of the steel belt 16 is (x2-x1)-2π(y3-y1); set the grease coating thickness to d, then the single grease coating amount is ((x2-x1)-2π(y3-y1))*d. When the initial positions of the two ends of the steel belt 16 are obtained, the grease spraying pressure is controlled, and the grease spraying width is adjusted by using the piston 18, and the coordinates of the nozzle 17 are calculated accordingly to spray the grease. It is worth noting that the longitudinal coating length of the steel strip 16 here can be adjusted according to the actual water blocking requirements, such as coating the entire width direction of the steel strip 16 with ointment, coating it partially, or coating it at the overlapping position.

[0069] Preferably, the origin coordinate in the present application is the location of the mounting seat. The present application does not limit the location of the origin coordinate, and only needs to ensure that the spray port 11, the steel belt 16 and the cable core 15 are relatively controllable.

[0070] Further, as an optional embodiment of the present invention, the optical cable grease coating method in the present application also includes:

[0071] Obtain the amount of the paste sprayed by the nozzle 17. When the amount of the paste applied is less than the set amount, adjust the paste pump to increase the amount of paste fed;

[0072] When the amount of oil paste sprayed from the nozzle 17 reaches the set spraying amount, the spraying work continues; when the amount of oil paste applied from the nozzle 17 cannot be adjusted to the set spraying amount, it is determined that the nozzle 17 is blocked, and the position of the piston 18 is adjusted. The piston 18 closes the opening of the nozzle 17 of the first spraying mechanism, and the control component switches the second spraying mechanism to work, and the second spraying mechanism continues to spray.

[0073] It is worth noting that the setting interval between the first spraying mechanism and the second spraying mechanism in the present application is equal to the gap between the oil spraying points on the cable core 15, so that after the first spraying mechanism is blocked, the oil sprayed by the second spraying mechanism continues to fall on the previous spraying point of the cable core 15 to fill the position of the first spraying mechanism, thereby realizing continuous production spraying of the oil and ensuring the continuous and stable production of optical cables.

[0074] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
