[0002] In the existing optical cable molding production, when the surface of the central reinforcement of the stranded optical cable is filled with water-blocking grease, the grease coating device includes reinforcement core limiting sleeves on both sides and a pressure filling device filled with grease in the middle. During coating, the reinforcement core enters the inner cavity of the pressure filling device from the grease wiping mold at the inlet end, so that the grease is continuously coated on the surface of the reinforcement core, and then the excess grease on the surface is recovered into the grease barrel through the grease wiping mold at the outlet end.

[0003] According to the Chinese patent application with application number 202311872781.9, a device for coating optical cable reinforcing core grease includes a base plate, on which are provided: a positioning assembly for positioning the axial position of the reinforcing core; a filling adjustment seat for adjusting the height and horizontal position of a filling gun; a filling gun for coating grease, which is arranged on the filling adjustment seat, and whose air inlet and air outlet are both connected to a constant pressure control system, and the control pressure of the constant pressure control system is adjustable.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-7 The present embodiment provides a device for coating an optical cable reinforcement core with grease, comprising a base 1, a filling gun 13 for coating the optical cable reinforcement core with grease, and a lifting device, wherein the lifting device is fixedly mounted on one side of the top of the base 1, one side of the filling gun 13 is fixedly connected to the lifting end of the lifting device, wherein the distance from the filling gun 13 to the top of the base 1 can be controlled by the lifting device, which is conducive to coating the outer surface of cable reinforcement cores of different sizes with grease by the filling gun 13.

[0031] A coating tube 4 for coating the ointment is detachably mounted at the bottom of the filling gun 13, and a clearing assembly is provided on the outside of the filling gun 13 for preventing blockage inside the coating tube 4. When the filling gun 13 is started, the ointment inside the filling gun 13 is evenly coated on the outer surface of the cable reinforcement core through the coating tube 4.

[0032] The dredging assembly includes a dredging tube 12 and a sliding track 14. The sliding track 14 can be detachably installed on the outside of the coating tube 4, and the sliding track 14 is perpendicular to the top of the base 1. A slider 17 is slidably installed in the inner cavity of the sliding track 14. The sliding track 14 can limit the sliding trajectory of the slider 17 to prevent the slider 17 from shaking and deflecting when sliding up and down, thereby improving the stability of the slider 17 sliding up and down.

[0033] An L-shaped connecting rod 15 is rotatably installed on one side of the slider 17 close to the open end of the sliding track 14, and the end of the L-shaped connecting rod 15 away from the slider 17 extends toward the base 1. When the bottom of the slider 17 and the bottom of the inner cavity of the sliding track 14 are in contact, the distance between the end of the L-shaped connecting rod 15 away from the slider 17 and the top of the base 1 is greater than the distance from the bottom of the coating tube 4 to the top of the base 1.

[0034] The support plate 11 is rotatably installed on the end of the L-shaped connecting rod 15 away from the slider 17, and the top of the support plate 11 and the end of the L-shaped connecting rod 15 away from the slider 17 are parallel to each other, wherein the longitudinal length of the support plate 11 is greater than the distance from the L-shaped connecting rod 15 to the coating tube 4 when the bottom of the slider 17 and the bottom of the inner cavity of the sliding track 14 are in contact. Therefore, when the slider 17 moves from top to bottom, the support plate 11 is rotated to allow a large degree of offset between the support plate 11 and the coating tube 4 until the bottom of the slider 17 and the bottom of the inner cavity of the sliding track 14 are in contact, and then the support plate 11 is rotated again until the support plate 11 is located directly below the coating tube 4, which is conducive to the normal sliding of the slider 17.

[0035] A vertical dredging pipe 12 is fixedly installed on one side of the top of the support plate 11 away from the L-shaped connecting rod 15. When the support plate 11 is rotated to the bottom of the coating tube 4, the middle of the top end of the dredging pipe 12 and the middle of the discharge port of the coating tube 4 are on the same horizontal line. Then the slider 17 is pushed to move the slider 17 away from the base 1 until the top of the slider 17 fits with the top of the inner cavity of the sliding track 14. The dredging pipe 12 can be partially inserted into the inner cavity of the coating tube 4, retaining the ointment flow channel for the inner cavity of the coating tube 4 to prevent the inner cavity of the coating tube 4 from being blocked by agglomerated ointment when it is used for the second time, thereby reducing the adverse effects on the external coating of the cable reinforcement core.

[0036] Furthermore, when the filling gun 13 is turned on, the slider 17 is moved to the top and fits the top of the inner cavity of the sliding track 14, and then the connecting end of the L-shaped connecting rod 15 and the slider 17 is rotated until the L-shaped connecting rod 15 is parallel to the top of the base 1, and the rotated L-shaped connecting rod 15 is fixed to prevent the support plate 11 from hindering the coating of grease on the outside of the cable reinforcement core.

[0037] The dredging component also includes a driving threaded rod 6. A threaded hole connected to the bottom of the slider 17 is provided at the top. The driving threaded rod 6 is installed in the inner cavity of the threaded hole through threaded cooperation. Both ends of the driving threaded rod 6 pass through the threaded holes and are rotatably connected to the inner wall of the sliding track 14. A reciprocating motor for driving the threaded rod 6 to rotate is fixedly installed on the top of the sliding track 14, wherein the top of the driving threaded rod 6 extends to the top of the sliding track 14 and is fixedly connected to the power output end of the reciprocating motor. Start the reciprocating motor to rotate the driving threaded rod 6, and move the slider 17 in cooperation with the threaded hole. The direction of movement of the slider 17 is controlled by controlling the direction of rotation of the reciprocating motor, and the slider 17 is fixed after movement.

[0038] An electric heating wire 16 for self-heating is fixedly installed in the inner cavity of the dredging tube 12. When the dredging tube 12 is inserted into the inner cavity of the coating tube 4, the electric heating wire 16 is energized to increase the temperature of the outer wall of the dredging tube 12. The dredging tube 12 transfers the heat to the ointment. The ointment melts due to the heat and under the action of gravity, it quickly drips along the outer wall of the dredging tube 12 and the inner wall of the coating tube 4 to the outside of the coating tube 4, which is conducive to removing the residual ointment inside the coating tube 4 and avoiding blockage of the inner cavity of the coating tube 4.

[0039] The top of the dredging tube 12 is set to a conical structure, which reduces the contact area between the top of the dredging tube 12 and the grease when it is inserted into the coating tube 4, and reduces the resistance when the dredging tube 12 is inserted into the inner cavity of the coating tube 4.

[0040] The electric heating wire 16 is set to a spiral structure, which increases the contact area between the electric heating wire 16 and the inner wall of the dredging pipe 12, reduces the time required for the outer wall of the dredging pipe 12 to heat up, and improves the uniformity of heating on the outside of the dredging pipe 12.

[0041] Two U-shaped clamps 5 are movably installed on the outer wall of the filling gun 13, and the sliding track 14 is fixedly connected to the outer wall of one of the U-shaped clamps 5 on the side away from its own open end, and connecting ear plates 20 are fixedly installed on the left and right sides of the two U-shaped clamps 5, wherein the two U-shaped clamps 5 and thus the two sides of the filling gun 13 are respectively sleeved on the outside of the filling gun 13 until the inner walls of the two U-shaped clamps 5 are completely fitted with the outer wall of the filling gun 13, and under the action of friction, the two U-shaped clamps 5 are sleeved on both sides of the filling gun 13.

[0042] A through hole is provided on the side wall of the connecting ear plate 20, wherein fastening bolts 9 are movably inserted in the inner cavities of the two through holes, and a fastening nut for fixing the two adjacent connecting ear plates 20 is installed on the outer wall of the fastening bolt 9 through threaded cooperation. After the two U-shaped clamps 5 are sleeved on the outside of the filling gun 13, the middle parts of the two adjacent through holes are at the same horizontal line, and then the fastening bolt 9 is inserted into one of the through holes, and extends through the other through hole to the outside of the adjacent connecting ear plate 20, and then the fastening nut is installed on the outside of the fastening bolt 9 through bolt cooperation, and the two adjacent connecting ear plates 20 are squeezed with the cooperation of the fastening bolt 9 and the fastening nut, so that the two U-shaped clamps 5 are close to each other, thereby improving the tightness of the fit between the inner wall of the U-shaped clamp 5 and the outer wall of the filling gun 13, preventing the U-shaped clamp 5 from falling off from the outside of the filling gun 13, and facilitating the disassembly and assembly between the dredging component and the filling gun 13.

[0043] Receiving holes are provided on one side of the top of the support plate 11 and on one end of the slider 17 close to the sliding track 14. The two ends of the L-shaped connecting rod 15 are rotatably installed in the inner cavities of the two accommodating holes respectively. The outer walls of the two ends of the L-shaped connecting rod 15 are elastically installed with a plurality of limiting balls 19 in a circular distribution. The inner cavities of the two accommodating holes are provided with a plurality of card grooves 18 matched with the limiting balls 19 in a circular distribution. The limiting balls 19 at the two ends of the L-shaped connecting rod 15 can improve the stability of the L-shaped connecting rod 15, the slider 17 and the support plate 11 after relative rotation, effectively prevent the L-shaped connecting rod 15 from resetting under the action of gravity after the relative rotation between the L-shaped connecting rod 15 and the slider 17, and at the same time improve the stability of the dredging tube 12 inserted into the coating tube 4.

[0044] Example 2, please refer to Figure 1-6 , further improvements made on the basis of Example 1:

[0045] A T-slot 22 is provided at the top of the support plate 11, and a T-block is slidably installed in the inner cavity of the T-slot 22. The top of the T-block extends to the top of the support plate 11 and is fixedly installed with a mounting frame 23. The cooperation between the T-slot 22 and the T-block can limit the sliding trajectory of the mounting frame 23 to prevent the mounting frame 23 from offset when moving back and forth.

[0046] The mounting frame 23 is located between the L-shaped connecting rod 15 and the dredging pipe 12. A cleaning blade 10 for cleaning the discharge end of the coating pipe 4 is fixedly installed on one side of the mounting frame 23 close to the dredging pipe 12. A notch matching the dredging pipe 12 is formed at the end of the cleaning blade 10 away from the mounting frame 23. When the dredging pipe 12 is inserted into the interior of the coating pipe 4, the mounting frame 23 is pushed to move toward the coating pipe 4 until the dredging pipe 12 is inserted into the notch. At this time, the cutting end of the cleaning blade 10 cuts the ointment remaining on the outer wall of the outlet end of the coating pipe 4 to prevent the ointment at the outlet end of the coating pipe 4 from agglomerating and causing its outlet end to be blocked.

[0047] A return spring 21 is fixedly installed on one side of the inner cavity of the T-slot 22, and one end of the return spring 21 away from the inner wall of the T-slot 22 is fixedly connected to one side of the T-block, wherein the return spring 21 can always apply a thrust to the T-block to move away from the clearing pipe 12. After the external thrust on the mounting frame 23 is removed, it is beneficial to quickly reset the mounting frame 23 and improve the stability of the mounting frame 23 on the top of the support plate 11.

[0048] The outer wall of the dredging tube 12 is fixedly sleeved with a material guide plate 8, the top of the material guide plate 8 is inclined in the direction away from the cleaning blade 10, and the material guide plate 8 is located below the cleaning blade 10. The ointment dripping along the outer wall of the dredging tube 12, the inner wall of the coating tube 4 and the cleaning blade 10 directly falls on the inclined end of the material guide plate 8, and then flows along the inclined end of the material guide plate 8, preventing the cleaned ointment from falling to the outside of the support plate 11, which is beneficial to improving the cleanliness of the dredging component and the subsequent use of the dredging component.

[0049] A bracket 2 is fixedly installed on one side of the top of the base 1, and a guide roller 3 and a support roller 7 for guiding the cable reinforcement core are rotatably installed on the top of the bracket 2. The support roller 7 is located below the guide roller 3. When the outer surface of the cable reinforcement core is coated with grease, it passes between the guide roller 3 and the support roller 7 and contacts with the outer walls of both at the same time, which is beneficial to the movement and positioning of the cable reinforcement core and prevents the cable reinforcement core from being offset when moving.

[0050] The top of the base 1 is provided with a leakage trough connected to the bottom thereof, and the leakage trough is located directly below the filling gun 13. A collecting device for collecting the ointment is installed at the bottom of the base 1, and the opening end of the collecting device is located directly below the leakage trough. The excess ointment on the outer surface of the cable reinforcement core and the ointment on the inclined end of the guide plate 8 all drip through the leakage trough into the collecting device under the action of gravity, thereby preventing waste of the ointment.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
