Description

Technical Field

[0001] The utility model relates to the technical field of plastic optical fiber production, and in particular to a novel environment-friendly vertical silicone fiber layer thickness controlled wall hanging machine and a fiber core wall hanging production line. Background Art

[0002] Plastic optical fiber (POF), also known as polymer optical fiber, is composed of a transparent polymer core with a high refractive index and a transparent polymer cladding with a low refractive index. Plastic optical fiber has the advantages of large diameter, good flexibility, low density, low loss window in the visible light region, low cost and processing cost, so it has been widely used in the fields of lighting, decoration, sensors, local area networks, and automotive control systems.

[0003] In existing plastic optical fibers, transparent polymer claddings are mostly made of Teflon material, as specifically disclosed in the invention patent with publication number CN1207588C. However, Teflon material cannot be degraded in the natural environment, and thus easily causes environmental pollution.

[0004] In addition, in the existing plastic optical fiber, the molding method of the transparent polymer cladding is mainly the immersion curing method; the immersion curing method is to immerse the corresponding solution on the outside of the fiber core, and then solidify the solution to form a transparent polymer cladding. The equipment corresponding to the immersion curing method can refer to the invention patent with publication number CN117275843B. The immersion curing method is not only efficient, but also relatively low in cost. However, during the curing process, the solution will flow downward along the outer circle of the fiber core under the action of gravity, resulting in the amount of solution in the upper layer of the fiber core being less than the amount of solution in the lower layer, and the thickness of the molded transparent polymer cladding is uneven, resulting in poor optical fiber quality.

[0005] Therefore, it is necessary to provide a technical solution to solve the above problems. Utility Model Content

[0006] Aiming at the shortcomings of existing plastic optical fibers, the utility model develops and improves them, and designs a new type of environmentally friendly vertical silicone fiber layer thickness controlled wall hanging machine, so as to prepare high-quality and environmentally friendly plastic optical fibers.

[0007] To achieve the above purpose, the utility model provides a new environmentally friendly vertical silicone fiber layer thickness control wall hanging machine, including a bracket, a material pipe, a material box and a first vulcanization component, wherein:

[0008] The bracket is provided with two guide members distributed up and down;

[0009] The material pipe is arranged vertically and between the two guide members. The material pipe is installed on the bracket and has a glue control structure arranged inside.

[0010] The material box is arranged below the material pipe and mounted on the bracket; the guide member arranged below the material pipe is located inside the material box;

[0011] The first vulcanization component is installed on the bracket, and is used for vulcanizing the fiber core whose glue is controlled by the glue control structure.

[0012] More specifically, the glue control structure includes a glue scraping mold and a thickness control mold, and the thickness control mold is arranged above the glue scraping mold.

[0013] More specifically, the glue control structure further includes a shaping mold, and the shaping mold is arranged above the thickness control mold.

[0014] More specifically, the guide member includes a guide wheel rotatably connected to the bracket, and an annular positioning groove is provided in the middle of the guide wheel.

[0015] More specifically, the inner bottom wall of the material box is inclined.

[0016] More specifically, the first vulcanization component is a vertical vulcanization furnace.

[0017] A fiber core wall hanging production line comprises an unwinding machine, a winding machine and the above-mentioned new environmentally friendly vertical silicone fiber layer thickness controlled wall hanging machine, wherein the unwinding machine and the winding machine are arranged on both sides of the new environmentally friendly vertical silicone fiber layer thickness controlled wall hanging machine.

[0018] More specifically, a second vulcanization component is provided between the novel environmentally friendly vertical silicone fiber layer thickness controlled wall hanging machine and the winding machine.

[0019] More specifically, the guide member disposed above the material pipe is located above an input port of the second vulcanizing component.

[0020] The technical effects of the utility model are:

[0021] The present application adopts a vertical structure so that the fiber core between the two guide members can move vertically. In this way, after the fiber core is coated with the liquid silicone in the material box, it will move upward in the vertical direction, and pass through the glue control structure for glue control during the vertical movement, and then pass through the first vulcanization component for vulcanization treatment. During this process, the silicone solution covering the surface of the fiber core will not be biased to any side of the fiber core, so that the thickness of the silicone layer finally prepared is uniform; that is, the plastic optical fiber prepared by the new environmentally friendly vertical silicone fiber layer thickness control wall hanging machine involved in the present application is of high quality and strong environmental protection, and the production efficiency is also relatively high.

[0033] Embodiment 1

[0034] See also Figure 2 to Figure 4 A novel environmentally friendly vertical silicone fiber layer thickness control wall hanging machine includes a bracket 31, a material pipe 32, a material box 33 and a first vulcanization component 34, wherein:

[0035] The bracket 31 is provided with two guide members 35 which are distributed up and down;

[0036] The material pipe 32 is vertically arranged and disposed between two guide members 35. The material pipe 32 is mounted on the bracket 31 and a glue control structure is disposed inside the material pipe 32.

[0037] The material box 33 is disposed below the material tube 32 and mounted on the bracket 31 ; the guide member 35 disposed below the material tube 32 is located inside the material box 33 ;

[0038] The first vulcanizing component 34 is mounted on the bracket 31 and is used for vulcanizing the fiber core that has been glued by the glue-controlling structure.

[0039] Compared with the prior art, the utility model involves a new type of environmentally friendly vertical silicone fiber layer thickness control wall hanging machine, which is different in that the present application adopts a vertical structure, and through the cooperation of two guide members 35, the fiber core can move vertically. In this way, after the fiber core is coated with the liquid silicone in the material box 33, it will move upward in the vertical direction, and during the vertical movement, it will be controlled by the glue control structure, and then vulcanized by the first vulcanization component 34. During this process, the silicone solution covering the surface of the fiber core will not be biased to any side of the fiber core, so that the thickness of the silicone layer finally prepared is uniform; that is, the plastic optical fiber prepared by the new type of environmentally friendly vertical silicone fiber layer thickness control wall hanging machine 3 involved in the present application is of high quality and strong environmental protection, and the production efficiency is also high.

[0040] In this embodiment, the glue control structure includes a glue scraping mold 36 and a thickness control mold 37, and the thickness control mold 37 is arranged above the glue scraping mold 36. In actual application, after the fiber core passes through the inside of the material box 33, a large amount of liquid silicone will adhere to its surface. Therefore, the fiber core must be scraped by the glue scraping mold 36. The glue scraping mold 36 can scrape off 98% of the excess liquid silicone on the surface of the fiber core, so that the excess silicone will flow back vertically into the material box 33, and the fiber core with the excess silicone scraped off will vertically pass through the thickness control mold 37. The thickness control mold 37 will remove the colloid on the surface of the fiber core that exceeds the required thickness and cast vertically, thereby making the silicone on the surface of the fiber core reach the required thickness.

[0041] Furthermore, the glue control structure further includes a shaping mold 38, which is arranged above the thickness control mold 37. In practical application, the shaping mold 38 can scrape off the excess silica gel produced on the surface of the fiber core during the casting process, so that the thickness of the silica gel on the surface of the fiber core output by the glue control structure is uniform, thereby improving the quality of the finally prepared plastic optical fiber.

[0042] In this embodiment, the guide member 35 includes a guide wheel rotatably connected to the bracket 31, and a circular positioning groove is provided in the middle of the guide wheel. The above design can ensure that the fiber core moves more smoothly and maintains a high concentricity with the material tube 32, thereby improving the glue control quality of the glue control structure.

[0043] In this embodiment, the inner bottom wall of the material box 33 is inclined. With the above design, the amount of silicone rubber in the upper layer of the material box 33 is greater than that in the lower layer, which facilitates the adhesion of the fiber core with liquid silicone rubber and reduces the waste of liquid silicone rubber.

[0044] In this embodiment, the first vulcanizing component 34 is a vertical vulcanizing furnace. In actual application, the liquid silicone is heated by the vertical vulcanizing furnace to produce a vulcanization effect.

[0045] Preferably, compressed air is passed through the vertical vulcanization furnace. It should be understood that directly heating to above 135°C in a conventional vulcanization furnace will cause the fiber core to turn yellow, thereby affecting the transmission of light; therefore, this solution uses compressed air to coat the fiber core so that heat is transferred to the fiber core through the compressed air, thereby avoiding changes in the fiber core.

[0046] Preferably, the vertical vulcanization furnace has a multi-section zoned heating structure inside, so that the external temperature of the fiber core can be gradually increased during the vertical movement, thereby reducing the risk of damage to the fiber core.

[0047] Embodiment 2

[0048] See also Figure 1 to Figure 4 A fiber core wall hanging production line includes an unwinding machine 1, a winding machine 2 and the above-mentioned new environmentally friendly vertical silicone fiber layer thickness controlled wall hanging machine 3, and the unwinding machine 1 and the winding machine 2 are arranged on both sides of the new environmentally friendly vertical silicone fiber layer thickness controlled wall hanging machine 3.

[0049] Furthermore, a second vulcanization component 4 is provided between the novel environmentally friendly vertical silicone fiber layer thickness controlled wall hanging machine 3 and the winding machine 2 .

[0050] The working process of the fiber core wall hanging production line is as follows: the fiber core output by the unwinding machine 1 is guided by the first guide wheel to the inside of the material tube 32. During the process, the fiber core will adhere to the liquid silicone inside the material box 33, and the fiber core entering the material tube 32 will have 98% of the excess silicone on its surface scraped off by the scraping mold 36, and then the silicone on its surface will be controlled to a specific thickness by the thickness control mold 37. Finally, the excess silicone generated on its surface during the casting process will be scraped off by the shaping mold 38 to complete the glue control process. Then the fiber core enters the first vulcanization component 34. The first vulcanization component 34 can make the silicone on the surface of the fiber core complete 98% vulcanization, thereby forming a silicon skin layer, and the fiber core that has completed the first vulcanization treatment is led out by the second guide wheel, and after being fully cooled, it enters the second vulcanization component 4, and the second vulcanization component 4 fully cures the silicone on the surface of the fiber core to form a high-quality plastic optical fiber, and the formed plastic optical fiber is wound up by the winding machine 2.

[0051] In this embodiment, the guide member 35 disposed above the material pipe 32 is located above the input port of the second vulcanizing component 4. With the above design, the fiber core outputted by the new environmentally friendly vertical silicone fiber layer thickness control wall hanging machine 3 can be vertically or obliquely input downward into the second vulcanizing component 4 to fully cool the fiber core; compared with the method of horizontally arranging the cooling section, this design can greatly reduce the floor space occupied by the fiber core wall hanging production line.

[0052] The above description is only a preferred embodiment of the present invention, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
