Description

Technical Field

[0001] This invention relates to an apparatus and method for testing the tensile strength of filler ropes during the production process. Background Technology

[0002] During optical cable production, due to the non-roundness of some cable core structures, filler ropes are required to ensure the roundness of the cable. The main function of the filler rope is to fill the gaps, and it also provides some support. Therefore, the tensile properties of the filler rope are essential to prevent the transmission performance of the optical fiber from being affected by the performance of the filler rope. Given the quality of the filler rope material, its tensile strength is of utmost concern. However, tests on the filler rope are usually conducted after production by sampling the material, which cannot promptly identify problems that may occur during the production process. Therefore, a testing device is needed to determine the performance of filler ropes during production. Summary of the Invention

[0003] The purpose of this invention is to provide an apparatus and method for testing the tensile strength of filler ropes during the production process, so as to solve the technical problems mentioned in the background art.

[0004] The technical solution for achieving the objective of this invention is: a device for testing the tensile strength of filler rope during production, comprising a fixed workbench, a temperature control device, a central axle, a clamping device, a length measuring device, and a diameter measuring device; the length measuring device for measuring the length of the filler rope and the diameter measuring device for measuring the diameter of the filler rope are respectively installed at intervals at both ends of the fixed workbench; the temperature control device is located inside the fixed workbench, and the central axle and clamping device are installed on the upper surface of the fixed workbench; there are two clamping devices located on both sides of the central axle; the volume of the central axle changes with temperature, and the temperature control device is used to control the temperature of the central axle.

[0005] Furthermore, the temperature regulating device employs a semiconductor cooler.

[0006] Furthermore, the cold end of the semiconductor cooler is connected to the central wheel axle for heat transfer.

[0007] Furthermore, the hot end of the semiconductor cooler is provided with a heat dissipation device.

[0008] Furthermore, the central axle includes a core and an outer sheath, with the outer sheath covering the outside of the core; the core is made of rare earth tungstate, and the outer sheath is made of polyurethane elastomer.

[0009] A method for testing the tensile strength of filler rope during the production process includes:

[0010] Step 1: Set up the testing device in the filler rope production line. The filler rope first passes through the length measuring device, then through the clamping device, then around the central axle at least once, then through another clamping device, and finally through the diameter measuring device. Step 2: Start the length measuring device to screen and locate the filler rope parts to be tested. Determine the segment length and test parts by measuring the length of the filler rope.

[0011] Step 3: The clamping device clamps both ends of the filler rope test area determined in Step 2.

[0012] Step 4: Activate the temperature control device to cause the central axle to expand.

[0013] Step 5: Observe the changes in the filler rope from a macroscopic perspective to determine the tensile strength of the filler rope;

[0014] Step 6: Test complete, release the clamping devices at both ends;

[0015] Step 7: By monitoring the diameter of the filler rope using a diameter measuring device, it can be determined whether the filler rope that has passed through the performance test area has completed the performance test.

[0016] Furthermore, the method for determining the tensile strength of the filler rope in step 5 is as follows: when the filler rope undergoes the same whitening phenomenon, i.e., plastic deformation, the performance is determined by the radius of the central wheel axle at this time. The larger the radius, the better the tensile strength performance.

[0017] Furthermore, the specific method for determining whether the performance test is completed in step 7 is as follows: if the filling rope shows obvious uneven diameter distribution, the performance test is completed; if the filling rope does not show obvious uneven diameter distribution, the performance test is not completed.

[0018] By adopting the above technical solution, the present invention has the following beneficial effects:

[0019] (1) The present invention can perform performance testing on the filling rope during the production process, thereby reducing the output of defective products and reducing the frequency of quality accidents caused by the filling rope.

[0020] (2) The central axle core of the present invention is made of rare earth tungstate. By utilizing its cold expansion and thermal contraction properties, the core temperature is changed by a temperature control device to achieve the purpose of changing the radius of the central axle. This is used to test the performance of the filling rope wound on the central axle, providing a more perfect force and making the force on each part of the filling rope more uniform.

[0021] (3) The outer sheath of the central wheel axle of the present invention is made of polyurethane elastomer. Because it has good elasticity and expansion properties, it can expand with the expansion of the core. At the same time, it has good low temperature resistance and is not easy to cause damage to the internal structure of the material under low temperature conditions.

[0022] (4) The hot end of the semiconductor cooler of the present invention is provided with a heat dissipation device, which can disrupt the heat transfer balance and make the cold end temperature lower, thereby controlling the temperature required for testing. Attached Figure Description

[0032] (Example 1)

[0033] See Figure 1 An apparatus for testing the tensile strength of filler rope during production includes a fixed workbench 1, a temperature regulating device 2, a central axle 3, a clamping device 4, a length measuring device 5, and a diameter measuring device 6. The length measuring device 5 and the diameter measuring device 6 are installed at intervals at both ends of the fixed workbench 1. The length measuring device 5 is used to select and locate the filler rope sections to be tested, determining the segment length and test location by measuring the length of the filler rope. The diameter measuring device 6 monitors the diameter of the filler rope to determine whether the filler rope that has passed through the performance testing area has completed the performance test. The temperature regulating device 2 is located inside the fixed workbench 1. The central axle 3 and the clamping device 4 are installed on the upper surface of the fixed workbench 1. There are two clamping devices 4, located on both sides of the central axle 3. The volume of the central axle 3 can change with temperature; the temperature regulating device 2 changes its volume by changing the temperature of the central axle 3.

[0034] In this embodiment, the temperature regulation device 3 uses a semiconductor cooler. Heat transfer between the N / P electrodes occurs through current flow. When a certain temperature difference is reached, the two electrodes reach equilibrium, and the forward and reverse heat transfers cancel each other out, keeping the N / P electrode temperatures constant. To achieve the ideal temperature, the hot end temperature can be lowered through heat dissipation, thereby disrupting the heat transfer equilibrium and lowering the cold end temperature, thus controlling the required test temperature.

[0035] The central axle 3 comprises a core 3-1 and an outer sheath 3-2, with the outer sheath 3-2 covering the outside of the core 3-1. The core 3-1 is made of rare-earth tungstate, and the outer sheath 3-2 is made of polyurethane elastomer. The cold end of the semiconductor cooler is connected to the central axle 3. Due to the thermal expansion and contraction properties of rare-earth tungstate, the core 3-1 begins to expand as the temperature decreases. The polyurethane elastomer covering the outside has good elastic expansion and contraction properties and can expand accordingly. Therefore, heat transfer can be achieved through the connection between the cold end of the semiconductor cooler and the central axle 3 to reduce the temperature of the central axle 3, thereby increasing the radius of the central axle 3. Furthermore, the polyurethane elastomer not only has good elastic expansion and contraction properties but also good low-temperature resistance, thus preventing damage to the internal structure of the material due to low temperatures.

[0036] A method for testing the tensile strength of filler rope during the production process includes:

[0037] Step 1: Set the testing device in the filler rope production line. The filler rope first passes through the length measuring device 5, then through the clamping device 4, then around the central axle 3 at least once, then through another clamping device 4, and finally through the diameter measuring device 6.

[0038] Step 2: Activate the length measuring device 5, select and locate the filler rope parts to be tested, and determine the segment length and test parts by measuring the length of the filler rope;

[0039] Step 3: Clamping device 4 clamps the two ends of the filler rope test area determined in Step 2.

[0040] Step 4: Activate the temperature regulation device 2 to cause the central axle 3 to begin expanding;

[0041] Step 5: Observe the changes in the filler rope from a macroscopic perspective to determine the tensile strength of the filler rope;

[0042] Step 6: Test complete, loosen the clamping devices at both ends;

[0043] Step 7: By monitoring the diameter of the filler rope using the diameter measuring device 6, it is determined whether the filler rope that has passed through the performance test area has completed the performance test.

[0044] When voids appear in the filler rope, it manifests macroscopically as a whitening phenomenon. At this time, the plastic deformation capacity of the filler rope can be seen from its appearance. The worse the plastic deformation capacity, the worse the tensile strength, the easier it is to produce voids first, and the more obvious the whitening phenomenon will be.

[0045] The method for determining the tensile strength of the filler rope in step 5 is as follows: when the filler rope undergoes the same whitening phenomenon, i.e., plastic deformation, the performance is determined by the radius of the central wheel axle 3 at this time. The larger the radius, the better the tensile strength performance.

[0046] The specific method for determining whether the performance test is completed in step 7 is as follows: if the filler rope shows obvious uneven diameter distribution, the performance test is completed; if the filler rope does not show obvious uneven diameter distribution, the performance test is not completed.

[0047] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
