Description

Technical Field

[0001] This invention relates to the field of optical cable production equipment technology, and in particular to an armor shaping device and a multi-layer armor synchronous forming device for armored optical cables. Background Technology

[0002] The optical cable armor layer is a metal strip, such as an aluminum strip, placed outside the optical cable core. The metal strip is wound around the outer periphery of the optical cable core in a spiral manner. After the metal strip is wound, it needs to be shaped so that the metal strip can better fit the optical cable core and at the same time reduce certain stress.

[0003] To address this, the industry has developed shaping devices. For example, Chinese patent CN218744075 U discloses a shaping device for the armor layer of optical cables, which shapes the armor layer of optical cables using ball bearings.

[0004] However, as Figure 1 As shown, the optical cable armor layer 201 of the optical cable 200 is directly rolled and shaped by the ball bearing 300. However, since the ball bearing and the optical cable armor layer are in point contact and have the same effect on all positions of the optical cable armor layer, and there may be inconsistencies in quality at different positions of the optical cable armor layer, the shaping effect is not good. Summary of the Invention

[0005] The main objective of this invention is to provide an armor shaping device and a multi-layer armor synchronous forming equipment for armored optical cables, aiming to provide an armor shaping device with better shaping effect.

[0006] To achieve the above objectives, the present invention provides an armor shaping device, comprising:

[0007] The cylindrical body has an installation cavity, and the two end walls of the installation cavity in the transverse direction are respectively provided with an inlet and an outlet; A rolling assembly includes a connector and a roller. The connector extends laterally, and its two ends are connected to two end walls. The roller is rotatably fitted around the connector. In a direction from the inside out, the roller includes an inner metal layer, a middle elastic layer, and an outer metal layer. The thickness of the middle elastic layer gradually increases in the direction from the outlet to the inlet. A drive assembly is connected to the cylinder drive to drive the cylinder to rotate.

[0008] During shaping, the optical cable enters from the inlet and exits from the outlet. The drive assembly drives the cylinder to rotate. Because the cylinder includes an inner metal layer, a middle elastic layer, and an outer metal layer, the thickness of the middle elastic layer gradually increases in the direction from the outlet to the inlet. That is, the middle elastic layer is thicker near the inlet and thinner near the outlet. Correspondingly, the inner metal layer is more likely to deform into shape near the inlet, but less likely to deform into shape near the outlet. Correspondingly, during shaping, the force applied to the optical cable armor layer gradually increases in the direction from the inlet to the outlet, so that the optical cable armor layer gradually deforms to complete the shaping, resulting in a better shaping effect.

[0009] In an embodiment of the present invention, the cylinder includes a first fixing ring and a second fixing ring arranged laterally opposite each other, and both the first fixing ring and the second fixing ring include the end wall and the annular side wall; The connector includes: The first connecting rod has one end connected to the end wall of the first fixing ring; and, The second connecting rod has one end connected to the other end of the first connecting rod, and the other end of the second connecting rod is connected to the end wall of the second fixing ring.

[0012] In an embodiment of the present invention, the other end of the first connecting rod is provided with a threaded hole, one end of the second connecting rod is provided with a threaded protrusion, the threaded protrusion is connected to the threaded hole, and the other end of the second connecting rod is provided as a threaded post, the threaded post passes through the end wall of the second fixing ring and is connected to a nut.

[0013] In an embodiment of the present invention, the rolling components are configured as a plurality of rolling components, which are arranged along the circumference of the cylinder.

[0014] In an embodiment of the present invention, in the rotation direction of the cylinder, the minimum thickness of the intermediate elastic layer on the rolling assembly located at the front is greater than the maximum thickness of the intermediate elastic layer on the rolling assembly located at the rear.

[0015] In an embodiment of the present invention, the intermediate elastic layer is made of silicone rubber.

[0023] Please see Figures 2 to 4 The present invention provides an armor shaping device 100, comprising: The cylindrical body 1 has a mounting cavity 1a, and the two end walls of the mounting cavity 1a in the transverse direction are respectively provided with an inlet 1b and an outlet 1c; The rolling assembly 2 includes a connector 21 and a roller 22. The connector 21 extends laterally, and its two ends are connected to the two end walls. The roller 22 is rotatably sleeved around the connector 21. In the direction from the inside out, the roller 22 includes an inner metal layer 221, a middle elastic layer 222, and an outer metal layer 223. The thickness of the middle elastic layer 222 gradually increases in the direction from the outlet 1c to the inlet 1b. The drive assembly 3 is connected to the cylinder 1 to drive the cylinder 1 to rotate.

[0024] During shaping, the optical cable 200 enters from the inlet 1b and exits from the outlet 1c. The driving component 3 drives the cylinder 1 to rotate. The roller 22 includes an inner metal layer 221, an intermediate elastic layer 222, and an outer metal layer 223. The thickness of the intermediate elastic layer 222 gradually increases in the direction from the outlet 1c to the inlet 1b. That is, the intermediate elastic layer 222 is thicker near the inlet 1b and thinner near the outlet 1c. Correspondingly, the inner metal layer 221 is more likely to deform into an outer shape near the inlet 1b, but less likely to deform into an outer shape near the outlet 1c. Correspondingly, during shaping, the force applied to the armor layer (i.e., the armor metal strip 201) of the optical cable 200 gradually increases in the direction from the inlet 1b to the outlet 1c, so that the armor layer of the optical cable 200 gradually deforms to complete the shaping, resulting in a better shaping effect.

[0025] In an embodiment of the present invention, the cylinder 1 includes a first fixing ring 11 and a second fixing ring 12 arranged laterally opposite each other, and both the first fixing ring 11 and the second fixing ring 12 include the end wall and the annular side wall; The connector 21 includes: The first connecting rod 211 has one end connected to the end wall of the first fixing ring 11; and, The second connecting rod 212 has one end connected to the other end of the first connecting rod 211, and the other end of the second connecting rod 212 is connected to the end wall of the second fixing ring 12.

[0026] In an embodiment of the present invention, the cylinder 1 is configured in two parts, namely, it is composed of the first fixing ring 11 and the second fixing ring 12, and the corresponding connecting member 21 is composed of the first connecting rod 211 and the second connecting rod 212. The structure is simpler and the rolling assembly 2 is easier to install.

[0027] In one embodiment, a plurality of first protruding keys 111 are provided on the outer side of the first fixing ring 11, and the plurality of first protruding keys 111 are distributed along the circumference of the first fixing ring 11. A plurality of second protruding keys 121 are provided on the outer side of the second fixing ring 12, and the plurality of second protruding keys 121 are distributed along the circumference of the second fixing ring 12. The armor shaping device 100 also includes a transmission gear 4. The inner side of the transmission gear 4 is provided with a plurality of first keyways 41 and a plurality of second keyways 42. The transmission gear 4 is sleeved on the periphery of the first fixing ring 11 and the second fixing ring 12. The plurality of first keyways 41 are connected to the plurality of first protruding keys 111, and the plurality of second keyways 42 are connected to the plurality of second protruding keys 121. The drive component 3 is connected to the transmission gear 4.

[0028] In this embodiment, the outer side of the first fixing ring 11 is provided with a plurality of first protruding keys 111, the outer side of the second fixing ring 12 is provided with a plurality of second protruding keys 121, and the inner side of the transmission gear 4 is provided with a plurality of first keyways 41 and a plurality of second keyways 42. The plurality of first keyways 41 are connected to the plurality of first protruding keys 111, and the plurality of second keyways 42 are connected to the plurality of second protruding keys 121, so as to achieve a stable connection between the first fixing ring 11 and the second fixing ring 12 and the transmission gear 4.

[0029] In one embodiment, the driving component 3 includes: Motor 31, having an output shaft; and, Drive gear 32 is connected to the output shaft of motor 31, and drive gear 32 is connected to the transmission shaft of motor 31. The moving gear 4 is engaged.

[0030] In this embodiment, the transmission gear is directly driven by the motor 31 and the drive gear 32, resulting in a structure... It is simple and stable.

[0031] In an embodiment of the present invention, the other end of the first connecting rod 211 is provided with a threaded hole 211a, one end of the second connecting rod 212 is provided with a threaded protrusion 212a, the threaded protrusion 212a is connected to the threaded hole 211a, and the other end of the second connecting rod 212 is provided with a threaded post 212b, the threaded post 212b passes through the end wall of the second fixing ring 12 and is connected to a nut A.

[0032] Specifically, in an embodiment of the present invention, the second connecting rod 212 includes a main body section 2121 and an extension section 2122. The outer diameter of the extension section 2122 is smaller than the outer diameter of the main body section 2121, so that an annular stepped surface facing the first connecting rod 211 is formed between the extension section 2122 and the main body section 2121. One section of the extension section 2122 is provided with threads to form the threaded protrusion 212a. The roller 22 is sleeved on the extension section 2122 and is located between the first connecting rod 211 and the annular stepped surface to be limited.

[0033] In an embodiment of the present invention, the scrolling component 2 is configured as a plurality of components, and the plurality of scrolling components are configured as a plurality of components. The moving component 2 is arranged along the circumference of the cylinder 1 to enable multi-layer shaping.

[0034] In an embodiment of the present invention, in the rotation direction of the cylinder 1, the minimum thickness of the intermediate elastic layer 222 on the front rolling assembly 2 is greater than the maximum thickness of the intermediate elastic layer 222 on the rear rolling assembly 2. This allows the force applied to the armor layer of the optical cable 200 to gradually increase. It should be noted that the front rolling assembly 2 refers to the rolling assembly 2 that first contacts the armor layer of the optical cable 200.

[0035] In an embodiment of the present invention, the intermediate elastic layer 222 is made of silicone rubber, which has good elasticity.

[0036] In embodiments of the present invention, the inner metal layer 221 and the outer metal layer 223 are made of copper. Copper possesses excellent ductility and resistance to deformation, providing a stable support framework for the intermediate elastic layer 222, preventing excessive indentation or displacement of the elastic layer during long-term compression and rolling. Furthermore, when in contact with the armor layer of the optical cable 200, its good toughness buffers instantaneous pressure, reducing scratches on the armor layer surface. Simultaneously, copper has excellent corrosion resistance, maintaining structural integrity even in humid or dusty working environments, preventing rust and impurities from contaminating the surface of the optical cable 200, effectively ensuring the stability of the shaping operation and the quality of the optical cable 200. In addition, copper has good thermal conductivity, quickly dissipating the heat generated by rolling friction, preventing excessively high local temperatures that could cause aging and deformation of the intermediate elastic layer 222, and extending the overall service life of the rolling assembly 2.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
