Description

Technical Field

[0001] The utility model relates to the technical field of optical cable molding, and more specifically to an optical cable reinforcing core grease coating device. Background Art

[0002] In the existing optical cable molding production, when filling the surface of the central reinforcement of the stranded optical cable 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.

[0003] During coating, the reinforcing core enters the inner cavity of the pressure filling device through the paste wiping mold at the inlet end, so that the paste is continuously coated on the surface of the reinforcing core, and then the excess paste on the surface is recovered into the paste barrel through the paste wiping mold at the outlet end.

[0004] The coating effect of this coating method is limited by the air pressure of the pressure filling device. Too high air pressure will lead to an increase in the amount of ointment on the surface of the reinforcing core, while too low air pressure will result in insufficient amount of ointment on the surface of the reinforcing core, making it difficult to ensure the anti-seepage ability of the cable core.

[0005] In summary, how to accurately control the amount of paste on the surface of the reinforcing core is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide an optical cable reinforcing core grease coating device, which can accurately, quantitatively, and intermittently coat the grease on the reinforcing core surface at a fixed distance.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The core of the utility model is to provide an optical cable reinforcing core grease coating device, which can accurately, quantitatively, and intermittently coat the grease on the reinforcing core surface at a fixed distance.

[0034] The utility model provides an optical cable reinforcing core grease coating device, comprising a bottom plate 1, on which are provided:

[0035] A positioning component, used to locate the axis position of the reinforcing core 01;

[0036] A filling adjustment seat, used to adjust the height and horizontal position of the filling gun 4;

[0037] The filling gun 4 for applying the ointment is arranged on the filling adjustment seat, and its air inlet 41 and air outlet 42 are both connected to the constant pressure control system, and the control pressure of the constant pressure control system is adjustable.

[0038] Among them, the positioning component is used to locate the axial position of the reinforcing core 01, so as to facilitate the alignment of the filling gun 4 and the reinforcing core 01; the positioning component can be set as a closed annular limiting structure, such as an existing wiping mold, etc., or it can be set as an openable and closable limiting structure such as an annular clamp.

[0039] The filling adjustment seat is arranged on the base plate 1, and the filling gun 4 is arranged on the filling adjustment seat, which is used to adjust the height and horizontal position of the filling gun 4; the filling adjustment seat is provided with a height adjustment mechanism and a horizontal position adjustment mechanism, one of which has a fixed end connected to the base plate 1 and a movable end connected to the fixed end of the other, and the movable end of the other is connected to the filling gun 4.

[0040] The height adjustment mechanism can be configured as a common linear motion mechanism such as a ball screw, an electric push rod, etc.; the horizontal position adjustment mechanism can be configured as a rotary motion mechanism or a linear motion mechanism with two sets of motion directions perpendicular to each other.

[0041] For example, an X-axis motion mechanism arranged along the reinforcing core conveying direction and a Y-axis motion mechanism arranged along the direction perpendicular to the reinforcing core conveying direction, the above X-axis motion mechanism and Y-axis motion mechanism can be set as common linear motion mechanisms such as ball screws and electric push rods.

[0042] Of course, considering that the influence of the position of the filling gun 4 in the direction of conveying the reinforcing core on the coating of the paste is far smaller than the influence of the height of the filling gun 4 and the position of the filling gun 4 in the vertical direction of the direction of conveying the reinforcing core on the coating of the paste, the horizontal position adjustment mechanism can also only adjust the position of the filling gun 4 in the vertical direction of the direction of conveying the reinforcing core.

[0043] The air inlet 41 and the air outlet 42 of the filling gun 4 are both connected to the constant pressure control system, which can adjust the pressure inside the filling gun 4 and then adjust the unit paste output of the filling gun 4 to meet the paste coating requirements of the reinforcing core 01 of different specifications.

[0044] The constant pressure control system may include an air pressure pump, a control valve and a pressure sensor. The air outlet of the air pressure pump is connected to the air inlet 41 of the filling gun 4 through an air inlet pipe, and the air inlet of the air pressure pump is connected to the air outlet 42 of the filling gun 4 through an air outlet pipe. The air inlet pipe is provided with a control valve for controlling the pipeline flow and a pressure sensor for detecting the pipeline pressure.

[0045] The positioning assembly, the filling adjustment seat and the filling gun 4 are all arranged on the base plate 1. The three can be connected to the base plate 1 through common detachable connection methods such as bolt connection and pin connection, or through non-detachable connection methods such as welding connection.

[0046] In order to facilitate the recycling of the ointment, preferably, the bottom plate 1 can be provided with an oil unloading port 11, and a recovery box for recovering the overflowing ointment is provided below the oil unloading port 11. The oil return tank can be connected to the ointment box for containing the ointment through a filter assembly, or connected to the ointment inlet 43 of the filling gun 4.

[0047] The shape and size of the oil unloading port 11 are determined according to the needs in actual production with reference to the prior art, and will not be described in detail here; the setting of the oil unloading port 11 can not only prevent the oil from dripping and contaminating the bottom plate 1, but also recycle the oil, saving production costs.

[0048] During production, first, the reinforcing core 01 is inserted into the positioning component, and the axial position of the reinforcing core 01 is positioned by using the positioning component; then the height and horizontal position of the filling adjustment seat are adjusted so that the filling gun 4 is set directly facing the reinforcing core 01 below; finally, the constant pressure control system is controlled to start, and the filling gun 4 is used to apply the paste to the surface of the reinforcing core 01.

[0049] When the control pressure P of the constant pressure control system is ≠ 0, the constant pressure control system uses air pressure to apply the paste to the surface of the reinforcing core 01 through the filling gun 4; when the control pressure P of the constant pressure control system is 0, the filling gun 4 is not driven by pressure and cannot output the paste to the outside, thereby realizing intermittent coating of the reinforcing core 01 at a fixed distance.

[0050] In this embodiment, the height and horizontal position of the filling adjustment seat are adjustable, which ensures the precise feeding and retraction of the filling gun 4 and the accurate alignment of the filling gun 4 and the reinforcing core 01;

[0051] The control pressure of the constant pressure control system is adjustable, and the control pressure can be adjusted according to the design specifications of the reinforcing core 01, so as to accurately control the unit paste output and coating time of the filling gun 4, and then accurately control the amount of paste coated on the surface of the reinforcing core 01 and the coating distribution state, thereby realizing quantitative and fixed-distance intermittent coating of the paste on the reinforcing core 01.

[0052] On the basis of the above embodiment, the structure of the positioning assembly is defined, and the positioning assembly includes a V-shaped guide wheel 21 and a roller 23 arranged along the conveying direction of the reinforcing core, the V-shaped guide wheel 21 is arranged above the reinforcing core 01, and the roller 23 is arranged below the reinforcing core 01, so that the V-shaped guide wheel 21 and the roller 23 cooperate to locate the axis position of the reinforcing core 01;

[0053] The V-shaped guide wheel 21 is connected to the base plate 1 through the guide wheel mounting frame 22, and the roller 23 is connected to the base plate 1 through the roller frame 24, and the heights of both the V-shaped guide wheel 21 and the roller 23 are adjustable.

[0054] Please refer to Figure 1 The two inclined surfaces of the V-shaped wheel groove of the V-shaped guide wheel 21 and the circumferential surface of the roller 23 are in contact with the circumferential surface of the reinforcing core 01. According to the three-point circle determination principle, the above three contact points can uniquely determine the axial position of the reinforcing core 01, thereby realizing accurate positioning of the reinforcing core 01.

[0055] In order to effectively position the reinforcing core 01 , the size of the V-shaped wheel groove is determined according to the minimum diameter of the reinforcing core 01 to ensure that the V-shaped wheel groove can press the reinforcing core 01 against the surface of the roller 23 and the reinforcing core 01 will not shake in the V-shaped wheel groove.

[0056] The V-shaped guide wheel 21 is arranged in the guide wheel mounting frame 22. In order to stably support the V-shaped guide wheel 21, the guide wheel mounting frame 22 is usually set as a U-shaped support frame, and the connecting shafts on both sides of the V-shaped guide wheel 21 are set in the U-shaped opening of the U-shaped support frame; similarly, the roller frame 24 is usually set as a U-shaped support frame, and the connecting shaft at one end of the roller 23 is set in the U-shaped opening of the U-shaped support frame.

[0057] The heights of both the V-shaped guide wheel 21 and the roller 23 are adjustable. A linear displacement mechanism such as an electric push rod may be provided between the U-shaped support frame and the connecting shaft to change the height of the connecting shaft relative to the U-shaped support frame, thereby changing the height of the V-shaped guide wheel 21 and the roller 23.

[0058] Alternatively, a plurality of connection positions may be provided between the U-shaped support frame and the connection shaft, and the height of the connection shaft may be adjusted by changing the connection positions, thereby changing the height of the V-shaped guide wheel 21 and the roller 23 .

[0059] For example, the guide wheel mounting frame 22 is provided with a plurality of guide wheel connection holes uniformly along the height direction, and the connecting shaft of the V-shaped guide wheel 21 is connected to the guide wheel connection hole through fasteners such as connecting pins and fastening bolts;

[0060] The roller frame 24 is evenly provided with a plurality of roller connecting holes along the height direction, and the connecting shaft of the roller 23 is connected to the roller connecting hole through fasteners such as connecting pins and fastening bolts.

[0061] The specific number, size and spacing of the guide wheel connecting holes and the roller connecting holes are determined according to the needs of actual production and will not be repeated here.

[0062] In this embodiment, the V-shaped guide wheel 21 cooperates with the roller 23 to accurately locate the axis position of the reinforcing core 01, and has a simple structure and is easy to adjust.

[0063] On the basis of the above embodiment, the structure of the filling adjustment seat is defined, and the filling adjustment seat includes an adjustment seat bottom plate 31, an adjustment screw rod 32, a movable slider 34 and a horizontal support rod 35 for installing the filling gun 4. The adjustment seat bottom plate 31 is detachably connected to the bottom plate 1, and the adjustment screw rod 32 is vertically arranged on the adjustment seat bottom plate 31;

[0064] The movable slider 34 is threadedly connected to the adjusting screw rod 32 , and the horizontal support rod 35 is threadedly connected to the movable slider 34 . The extending direction of the horizontal support rod 35 is perpendicular to the conveying direction of the reinforcing core.

[0065] Please refer to Figure 1 The adjusting screw rod 32 is rotatably arranged on the adjusting seat bottom plate 31. When the adjusting screw rod 32 is rotated, since the height of the adjusting screw rod 32 remains unchanged, the movable slider 34 threadedly sleeved on the adjusting screw rod 32 is driven to slide up and down along the adjusting screw rod 32, thereby driving the filling gun 4 to move in the height direction;

[0066] The horizontal support rod 35 is threadedly connected to the movable slider 34. By rotating the horizontal support rod 35, the horizontal support rod 35 moves relatively closer to or farther away from the movable slider 34 in the direction perpendicular to the conveying direction of the reinforcing core, thereby driving the filling gun 4 to move in the direction perpendicular to the conveying direction of the reinforcing core.

[0067] In order to limit the deflection of the movable slider 34 during the up and down movement, guide rods 33 are provided on both sides of the adjusting screw rod 32, and the movable slider 34 is sleeved outside the guide rods 33 so that the guide rods 33 can be used to limit the moving direction of the movable slider 34.

[0068] The pitch of the connecting thread between the adjusting screw 32 and the movable slider 34 determines the height adjustment accuracy of the filling gun 4, and the pitch of the connecting thread between the movable slider 34 and the horizontal support rod 35 determines the horizontal adjustment accuracy of the filling gun 4. The specific dimensions such as the pitch of the above two connecting threads are determined according to the adjustment accuracy requirements of the filling gun 4 in actual production, and will not be repeated here.

[0069] In this embodiment, height adjustment and horizontal adjustment of the filling gun 4 are achieved through threaded connection, the structure is simple, the adjustment is convenient, and the adjustment accuracy is high, and the micro-distance movement of the filling gun 4, especially the filling head 44, is achieved.

[0070] Preferably, in order to adjust the position of the filling gun 4 in the direction of conveying the reinforcing core, an adjustment seat bottom plate 31 can be provided to be bolted to the bottom plate 1, and the adjustment seat bottom plate 31 is provided with a waist-shaped connection for installing fastening bolts, and the long axis direction of the waist-shaped hole is parallel to the conveying direction of the reinforcing core.

[0071] Therefore, the connection position between the seat bottom plate 31 and the bottom plate 1 can be fine-tuned by adjusting the position of the fastening bolt in the waist-shaped hole, thereby adjusting the position of the filling gun 4 in the conveying direction of the reinforcing core.

[0072] On the basis of the above embodiment, the structure of the filling gun 4 is defined. The filling gun 4 includes a filling cavity and a filling head 44. The filling cavity is connected to the constant pressure control system. The filling head 44 includes a telescopic needle 441, a mounting portion 442 for connecting with the filling cavity, a filling portion 444 for applying ointment, and a connecting portion 443 connecting the mounting portion 442 and the filling portion 444.

[0073] The telescopic needle 441 is sleeved in the through hole of the connecting portion 443 . The telescopic needle 441 can slide along the through hole under the action of air pressure so as to push the ointment out of the filling portion 444 .

[0074] The mounting portion 442 is connected to the filling cavity, and the two can be connected by common connection methods such as threaded connection, bolt connection, pin connection, etc. Figure 2 The mounting portion 442 is threadedly connected to the filling cavity, has strong sealing performance, is easy to process, and the horizontal position of the filling head 44 can be adjusted by rotation so that the outlet end face of the filling portion 444 fits the circumferential surface of the reinforcing core 01.

[0075] A transition conical surface is usually provided at the connection between the mounting portion 442 and the connecting portion 443, and the diameter of the transition conical surface gradually decreases from one end close to the mounting portion 442 to one end close to the connecting portion 443, so that the grease can smoothly enter the through hole of the connecting portion 443 from the mounting portion 442 along the transition conical surface.

[0076] The telescopic needle 441 is arranged in the mounting part 442, and part or all of the telescopic needle 441 is slidably sleeved in the through hole of the connecting part 443. The telescopic needle 441 can use air pressure to push the grease out of the filling part 444. When the pressure in the filling cavity increases, the telescopic needle 441 moves toward the outlet end of the filling part 444, pushes out the grease in the filling part 444, and coats the grease on the surface of the reinforcing core 01;

[0077] On the contrary, when the pressure in the filling chamber decreases, the telescopic needle 441 moves away from the outlet end of the filling portion 444 , and the telescopic needle 441 leaves the through hole of the connecting portion 443 , and the grease enters the filling portion 444 through the connecting portion 443 under the action of its own weight.

[0078] The extension and retraction frequency of the retractable needle 441 is determined by the change frequency of the control pressure of the constant pressure control system, which determines the coating time t1 of the filling gun 4 and the gap time t2 between two adjacent coating times, and further determines the distribution of the coated section and the uncoated section in the extension direction of the reinforcing core 01, that is, the coating distribution state of the reinforcing core 01.

[0079] To facilitate the control of the unit paste output of the filling gun 4, please refer to Figure 2 The telescopic needle 441 includes a telescopic needle body and a telescopic needle head. The telescopic needle body is arranged in the mounting portion 442. The diameter of the large end of the telescopic needle head is larger than the through hole of the connecting portion 443, and the diameter of the small end is smaller than the through hole of the connecting portion 443. Therefore, the telescopic needle head can only be partially inserted into the through hole of the connecting portion 443.

[0080] The aperture of the filling portion 444 is usually larger than the aperture of the connecting portion 443 , so as to reduce the flow velocity of the grease by increasing the flow channel area, thereby accurately controlling the grease output of the filling gun 4 per unit time.

[0081] In this embodiment, the coating distribution state of the reinforcing core 01 can be adjusted by adjusting the change frequency of the control pressure of the constant pressure control system and the telescopic frequency of the telescopic needle 441, and the unit ointment output of the filling gun 4 can be adjusted by adjusting the control pressure, which allows accurate regulation and convenient control.

[0082] Preferably, the outlet end face of the filling portion 444 can be set to be an arc surface, which is used to fit with the cylindrical surface of the reinforcing core 01 so that the paste flows from both sides of the arc surface to the lower end of the reinforcing core 01, thereby coating the reinforcing core 01 all around.

[0083] In a specific embodiment, in order to meet the coating requirements of reinforcing cores 01 of different specifications, the control pressure of the constant pressure control system is set to 0.05-0.3MPa;

[0084] The diameter of the connecting portion 443 of the filling head 44 of the filling gun 4 is 2 mm, the diameter of the filling portion 444 is 3.2 mm, and the radius of the arc surface of the filling portion 444 is 2-5 mm, so that the filling portion 444 can fit the circumferential surface of the reinforcing core 01 of different specifications;

[0085] The sum L of the length of the connecting portion 443 and the length of the filling portion 444 is 30-40 mm, and the length L1 of the filling portion 444 is 5-25 mm, so as to ensure the relative stability of the unit paste output under different conveying speeds of the filling gun 4 on the reinforcing core 01.

[0086] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0087] The above is a detailed introduction to the optical cable reinforcing core grease coating device provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
