[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 ,in, Figure 1 A schematic diagram of a preferred embodiment of the optical cable reinforcing core pultrusion molding apparatus provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the internal structure of the circular groove shown. Figure 3 for Figure 1 The diagram shows the structural schematic of the compression block. Figure 4 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 5 for Figure 2 The enlarged schematic diagram of section B is shown below; Figure 6 for Figure 4 The enlarged schematic diagram of section C is shown below; Figure 7 for Figure 4 The diagram shown is an enlarged view of part D. The optical cable reinforcing core pultrusion molding device includes: mounting frame one 1 and mounting frame two 2. A lifting assembly 6 is installed at the bottom of mounting frame one 1, and the lifting assembly 6 is connected to a stretching and plasticizing device 10. Several sets of collecting grooves 9 are uniformly fixedly installed at the bottom of mounting frame one 1. Several sets of circular grooves 8 are uniformly opened at the top of mounting frame one 1. A valve assembly 5 is installed at the lower outlet of each set of circular grooves 8. A storage chamber 12 is opened in the middle of the sets of circular grooves 8. The storage chamber 12 contains a heated glass core. A discharge pipe 13 is installed between the storage chamber 12 and the circular grooves 8. Each set of storage chambers 12 and the circular grooves 8... A rectangular cavity 14 is provided between each of the slots 8. The rectangular cavity 14 passes through the discharge pipe 13. A rectangular opening is provided at the bottom of the rectangular cavity 14 and passes through the bottom of the mounting frame 1. A baffle 2 15 is slidably connected inside the rectangular cavity 14. A discharge port 16 is provided on the side wall of the baffle 2 15. Several sets of grooves 17 are provided at the bottom of the mounting frame 1. A linkage component 11 is installed between the inner wall of each set of grooves 17 and the baffle 2 15. A drive component 4 is installed at the bottom of the mounting frame 1. The drive component 4 is connected to the linkage component 11. The mounting frame 2 is fixed to the top of the mounting frame 1. An extrusion component 3 is installed on the top of the mounting frame 2.

[0027] The extrusion assembly 3 includes a cylinder 31, which is fixed to the top of the mounting frame 2 and passes through the mounting frame 2. The output end of the cylinder 31 is fixedly mounted with a mounting plate 33, and several sets of pressure blocks 32 are evenly fixedly mounted on the bottom of the mounting plate 33.

[0028] Each set of pressing blocks 32 is located directly above each set of circular grooves 8. After the internally heated glass core is transported to the interior of each set of circular grooves 8 through the discharge port 16, the output end of the cylinder 31 will push the mounting plate 33 downward, so that the pressing blocks 32 squeeze the glass core inside the circular groove 8. At the same time, the drive component 4 and the light strip valve component 5 are driven to squeeze the glass core into strips, which are then stretched and shaped by the stretching and shaping device 10, and finally fall into the collection tank 9 for cooling.

[0029] The drive assembly 4 includes mounting blocks 42. Two sets of mounting blocks 42 are evenly fixed to the top of the mounting frame 1. A motor 41 is fixedly mounted on the outer wall of the mounting block 42 located at the right end of the mounting frame 1. The output end of the motor 41 passes through the mounting block 42. A bidirectional threaded rod 45 is fixedly mounted on the output end of the motor 41. The other end of the bidirectional threaded rod 45 is rotatably connected to the side wall of another set of mounting blocks 42. Threaded blocks 44 are threaded to both ends of the bidirectional threaded rod 45. Connecting rods 43 are fixedly mounted on the front and rear outer walls of both sets of threaded blocks 44. Each set of connecting rods 43 is connected to the valve assembly 5. A guide rod 46 is fixedly mounted between the two sets of mounting blocks 42. The guide rod 46 is slidably connected to the two sets of threaded blocks 44.

[0030] The output end of motor 41 drives the bidirectional threaded rod 45 to rotate, causing the two sets of threaded blocks 44 to drive the valve assembly 5 and the linkage assembly 11 through the connecting rod 43.

[0031] The valve assembly 5 includes a slide rail 52. Several sets of slide rails 52 are uniformly fixedly installed on the top of the mounting bracket 1 at the outlet of the circular groove 8. A baffle 51 is slidably connected between every two sets of slide rails 52. The top of each baffle 51 is in close contact with the outlet of the circular groove 8. A connecting strip 53 is fixedly installed on the side wall of each baffle 51. The other end of each connecting strip 53 is fixedly connected to the linkage assembly 11 and the connecting rod 43 respectively.

[0032] The connecting rod 43 drives the connecting bar 53 to push each set of baffles 51 to slide along the slide rail 52 until they leave the outlet of the circular groove 8. At the same time, the linkage component 11 will drive the baffle 15 to move upward, so that the discharge port 16 and the discharge pipe 13 are misaligned, thereby stopping the feeding.

[0033] The linkage component 11 includes a rotating shaft 114. Several sets of rotating shafts 114 are rotatably connected to the inner wall of the groove 17. Gear 111 and gear 215 are fixedly installed at the front and rear ends of the outer wall of each set of rotating shafts 114, respectively. A rack 112 is fixedly installed at the top of each set of connecting strips 53. The rack 112 meshes with the gear 111. A rack 213 is fixedly installed at the bottom of each set of baffles 215. The rack 213 meshes with the gear 215.

[0034] As the connecting bar 53 pushes the baffle 1 51 to move, the rack 1 112 will drive the gear 1 111 to rotate, which will cause the shaft 114 to drive the gear 2 115 to rotate, thereby causing the rack 2 113 to move upward, so that the lower end of the baffle 2 15 blocks the outlet of the discharge pipe 13, thus automatically stopping the feeding.

[0035] The lifting assembly 6 includes a second motor 61, which is fixed to the bottom of the mounting frame 1. The output end of the second motor 61 extends through the mounting frame 1, and a threaded rod 62 is fixedly installed at the output end of the second motor 61. A threaded sleeve 65 is threadedly connected to the outer wall of the threaded rod 62. Several sets of rectangular rods 64 are evenly fixedly installed on the outer wall of the threaded sleeve 65. The inner sidewalls of the four sets of support columns of the mounting frame 1 are all provided with sliding grooves 63. The other end of each set of rectangular rods 64 is slidably connected to the inner wall of the sliding groove 63. A stretching and shaping device 10 is fixedly installed in the middle of each set of rectangular rods 64.

[0036] Each set of stretching and shaping devices 10 is aligned with the bottom of the circular groove 8 and the top of the collection groove 9. When the extruded reinforcing core enters the stretching and shaping device 10, the output end of the motor 2 61 drives the threaded rod 62 to rotate continuously, so that the threaded sleeve 65 drives several sets of rectangular rods 64 to move up and down along the slide groove 63, thereby allowing the stretching and shaping device 10 to continuously stretch and shape the reinforcing core.

[0037] A control device 7 is fixedly installed on the outer wall of the mounting bracket 1. The control device 7 is electrically connected to the motor 61 and is a PLC controller.

[0038] The working principle of the optical cable reinforcing core pultrusion molding device provided by this utility model is as follows: After the internally heated glass core is transported from the storage chamber 12 to the interior of each set of circular grooves 8 through the discharge port 16, the drive component 4 will drive the valve component 5 to open through the linkage component 11. At the same time, the linkage component 11 will also drive the baffle 15 to move upward, so that the discharge port 16 is misaligned with the outlet of the discharge pipe 13, thereby stopping the feeding. Then, the extrusion component 3 extrudes the glass core inside the circular groove 8, so that the glass core is extruded into strips. Then, the lifting component 6 controls the stretching and shaping device 10 to stretch and shape the glass core, and finally it falls into the collection tank 9 for cooling.

[0039] Compared with related technologies, the optical cable reinforcing core pultrusion molding device provided by this utility model has the following advantages:

[0040] Beneficial effects:

[0041] Through the interaction of components such as motor 41, connecting rod 43, threaded block 44, and bidirectional threaded rod 45, multiple sets of connecting bars 53 can be simultaneously controlled to push baffle 51 away from the bottom of circular groove 8.

[0042] As the connecting bar 53 pushes the baffle 1 51 to move, the rack 1 112 drives the gear 1 111 to rotate, which in turn drives the shaft 114 to drive the gear 2 115 to rotate, thereby causing the rack 2 113 to move upward, so that the lower end of the baffle 2 15 blocks the outlet of the discharge pipe 13, thus automatically stopping the feeding. Through the mutual linkage of the above components, it is possible to effectively block the lower outlet of the circular groove 8 while feeding. During extrusion, the outlet of the discharge pipe 13 is blocked as the baffle 1 51 leaves the outlet of the circular groove 8.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
