The radius of the reinforcing core 10 can be directly determined according to the size of the selected reinforcing core 10, the coating thickness of the water-blocking paste on the periphery of the reinforcing core 10 is directly determined according to the water-blocking requirement and the size of the reinforcing core 10, which are common size standards for optical fiber production, and the description is omitted.
As another preferred calculation mode of the water-blocking paste extrusion flow rate threshold, the water-blocking paste extrusion flow rate threshold is calculated by:
v= [ pi (r+r1+r2) or-pi R, 1 (formula 2)
Wherein V is the coating amount of the water-blocking paste on the periphery of the reinforcing core 10 in unit length, R is the radius of the reinforcing core 10, R1 is the coating thickness of the water-blocking paste on the periphery of the reinforcing core 10, and R2 is the redundant coating thickness of the water-blocking paste.
Preferably, r2 is a redundant coating thickness of the water-blocking paste, where the redundant coating thickness makes the extrusion flow threshold of the water-blocking paste correspondingly rise, and makes the proper amount of the water-blocking paste entering the coating die 8 exceed the standard value, so that the amount of the water-blocking paste coated on the periphery of the reinforcing core 10 is greater than the standard value, and after the correction by the aperture controller 9, the size of the reinforcing core 10 coated with the water-blocking paste under the standard size is obtained. The redundant water-blocking paste coating thickness makes it possible to avoid the problem of insufficient water-blocking paste coating amount in the peripheral part area of the reinforcing core 10, which is caused by the loss amount of water-blocking paste sprayed onto the coating die 8 and the uneven coating layer formed on the periphery of the reinforcing core 10, etc. at the time of coating the reinforcing core 10. Excessive water-blocking paste can be scraped off by the aperture controller 9, but the water-blocking paste at the defect part cannot be recovered, and defective products and bad products are easily caused, so that the traditional water-blocking paste coating waste is serious, and the problem is the core problem solved by the application. Preferably, the thickness of the redundant water-blocking paste coating is 0.1-0.2 mm.
Taking a steel wire reinforced core 10 with the diameter of 1.35mm as an example, according to the coating standard and requirement, the size of a first through hole 804 of a water blocking paste filling die is 2.5mm, the water blocking effect can be achieved when the thickness of a single-sided coating of the reinforced core 10 reaches 0.3mm, the thickness of a double-sided coating is 0.6mm, the double-sided coating is controlled to have redundant coating thickness, the thickness of an actual coating layer is between 0.8mm and 1.0mm, and the sectional area of the water blocking paste is 2.198mm 2 ~2.9045mm 2 The water-blocking paste volume required by the 1m steel wire reinforced core 10 to be coated can be obtained, the water-blocking paste extrusion flow threshold can be obtained, and the extrusion flow of the water-blocking paste is limited according to the water-blocking paste extrusion flow threshold.
After the size of the steel wire reinforced core 10 is confirmed, the ointment coating amount is confirmed, the water-blocking paste extrusion flow threshold is confirmed, and the rotation frequency of the rotating member 1 is regulated and controlled by the controller, so that the water-blocking paste extrusion amount is controlled. The extrusion amount of the water-blocking paste is in a dynamic balance state, the flowmeter senses the extrusion amount of the water-blocking paste, the flowmeter transmits the sensed flow to the controller, and the controller controls the rotation frequency of the rotating piece 1 in real time.
Further, as a preferred embodiment of the present invention, the coating die 8 in the present application includes a die body 801, a first through hole 804 passing through both ends of the die body 801, and at least one nozzle 802 provided along the outer circumference of the first through hole 804 in the die body 801, the nozzle 802 being in communication with the extrusion line 7 for spraying the water-blocking paste in the water-blocking paste extrusion device to the outer circumference of the reinforcing core 10 to form a water-blocking paste coating layer on the outer circumference of the reinforcing core 10.
Further preferably, the mold main body 801 in the present application is of a cylindrical structure, and two ends of the first through hole 804 are narrow openings, so as to ensure that the corresponding input and output of the reinforcing core 10 can be ensured, and the narrow openings at two ends of the first through hole 804 can avoid external dust, moisture and the like from entering the mold main body 801 as much as possible, so as to affect the quality of the water-blocking paste. Further, the number of the nozzles 802 is plural, and the plurality of nozzles 802 are uniformly distributed on the mold main body 801 along the circumferential direction, so that a uniformly coated water-blocking paste layer is formed on the periphery of the reinforcing core 10, and the uniformity of the water-blocking paste coating on the periphery of the reinforcing core 10 is ensured. Preferably, the number of nozzles 802 is 6, and 6 nozzles 802 may substantially achieve full coverage of the periphery of the reinforcing core 10. Alternatively, the nozzles 802 may be provided along the axial extending direction of the mold main body 801, but the output of each nozzle 802 needs to be strictly controlled so that the outer periphery of the reinforcing core 10 is formed with a water-blocking paste thickness conforming to the coating size.
Further, as a preferred embodiment of the present invention, a return pipe 803 is further connected to the bottom of the mold body 801 in the present application, and the return pipe 803 is in communication with the first through hole 804, and is mainly used for collecting the water-blocking paste in the first through hole 804 that is not sprayed on the reinforcing core 10, or the water-blocking paste that is dropped from the reinforcing core 10. The other end of the return pipe 803 is in communication with the water-blocking paste storage device 2, which is mainly used for recovering the surplus water-blocking paste for secondary use. The conventional water-blocking paste storage device 2 has an upper opening, which directly receives the water-blocking paste dropped from the coating die 8, so that the water-blocking paste is contaminated with more dust and impurities nearby, and the amount of impurities in the water-blocking paste is seriously increased, resulting in damage to the extrusion screw 4. The die main body 801 is arranged to be basically closed, and the output quantity of the water-blocking paste is controlled, so that the redundancy quantity of the water-blocking paste is smaller, the probability of dust contamination is reduced, and the overall quality of the water-blocking paste is improved.
Preferably, a filter screen is further arranged between the return pipe 803 and the water-blocking paste storage device 2, and the filter screen can intercept dust impurities and the like, so that the overall quality of the water-blocking paste entering the water-blocking paste storage device 2 is ensured, the impurity content of the water-blocking paste is reduced, and the service life of the extrusion screw 4 is prolonged. Preferably, the return line 803 is blocked in order to avoid impurities trapped at the filter screen. The filter screen is preferably arranged on the water-blocking paste storage device 2, which has a larger cross-sectional area than the return pipe 803, and the water-blocking paste storage device 2 has a larger size, the probability of blocking is lower than the return pipe 803, and the cleaning is convenient to open.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
