DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0019] like Figure 1 — Figure 3As shown, this embodiment discloses an extrusion device for producing and processing plastic optical fiber, including a mounting table 1, a motor 2 is arranged on one side of the upper end of the mounting table 1, a transmission member 3 is arranged on the output end of the motor 2, the transmission member 3 is fixedly installed in the middle of the upper end of the mounting table 1, an extrusion mechanism 4 is arranged on the upper part of the outer surface of the transmission member 3, a heating device 6 is arranged on the side of the outer surface of the mounting table 1 away from the motor 2, the heating device 6 is sleeved on the middle part of the outer surface of the extrusion mechanism 4, and a feeding device 5 is arranged on the side of the outer surface of the extrusion mechanism 4 close to the transmission member 3.

[0020] Specifically, in the process of plastic optical fiber production, the staff can pour the relevant raw materials into the inner cavity of the feeding device 5, stir the relevant raw materials evenly through the feeding device 5, and then the staff starts the motor 2, so that the motor 2 drives the extrusion mechanism 4 to operate through the transmission member 3, so that the extrusion mechanism 4 pushes the raw materials from the inner cavity of the feeding device 5 into the inner cavity of the extrusion mechanism 4. At the same time, the staff starts the heating device 6 to heat the raw materials in the inner cavity of the extrusion mechanism 4 to melt the raw materials. After the melted raw materials are fully mixed in the inner cavity of the extrusion mechanism 4, they are pushed into the inner cavity of the cleaning device 7, and the impurities in the melted raw materials are cleaned by the cleaning device 7, and then the melted raw materials are extruded from the inner cavity of the cleaning device 7.

[0021] Furthermore, before production, the staff can adjust the support member 8 so that the support member 8 can support the extruded plastic optical fiber.

[0022] Before the production of plastic optical fiber, in order to make the raw materials for the production of plastic optical fiber be evenly mixed together, such as Figure 4 As shown, the feeding device 5 includes a feeding hopper 51 and a second motor 53. The second motor 53 is fixedly installed in the middle of the upper end of the feeding hopper 51. A limiting member 52 is arranged at the lower end of the feeding hopper 51. The limiting member 52 is sleeved on the side of the outer surface of the extrusion mechanism 4 close to the transmission member 3. The inner cavity of the limiting member 52 is communicated with the inner cavity of the extrusion mechanism 4. A transmission handle 54 is arranged in the middle of the inner cavity of the feeding hopper 51. The upper end of the transmission handle 54 is fixedly connected to the output end of the second motor 53. A stirring member 55 is arranged in the middle of the outer surface of the transmission handle 54.

[0023] Specifically, before the production of plastic optical fiber, the staff can put the relevant raw materials into the inner cavity of the lower hopper 51, and then start the motor 2 53 to drive the transmission handle 54 to rotate. When the transmission handle 54 rotates, it will drive the stirring member 55 to rotate. The rotation of the stirring member 55 can stir the relevant raw materials in the inner cavity of the lower hopper 51, so that the relevant raw materials are evenly mixed.

[0024] Furthermore, after the relevant raw materials in the inner cavity of the lower hopper 51 are mixed evenly, the staff can pull out the blocking plate in the limiter 52 to allow the raw materials in the inner cavity of the lower hopper 51 to enter the inner cavity of the extrusion mechanism 4 for the next step of processing.

[0025] In order to promote the movement of the raw materials for producing plastic optical fiber dropped from the feeding device 5, the inner cavity thereof is heated and melted by the heating device 6 during the movement and is fully mixed, as shown in FIG. Figure 5 As shown, the extrusion mechanism 4 includes an extrusion shell 41, which is fixedly installed on the outer surface of the transmission member 3. A plurality of limiting grooves 411 are provided in the middle section of the inner cavity of the extrusion shell 41. An extrusion member 42 is provided in the middle of the inner cavity of the extrusion shell 41. One end of the extrusion member 42 away from the cleaning device 7 is fixedly connected to the end face of the transmission rod in the transmission member 3. A stirring mechanism 43 is provided in the inner cavities of the plurality of limiting grooves 411.

[0026] Specifically, when the evenly mixed raw materials in the inner cavity of the unloading device 5 enter the inner cavity of the extrusion shell 41, the extrusion piece 42 will drive the raw materials entering the inner cavity of the extrusion shell 41 to move to the side away from the transmission piece 3. During this process, the heating device 6 will heat the raw materials in the inner cavity of the extrusion shell 41 to melt them. After the heated and melted raw materials pass through the stirring mechanism 43 under the push of the extrusion piece 42, the various substances in the heated raw materials can be evenly mixed through the stirring mechanism 43. After that, the mixed raw materials enter the inner cavity of the cleaning device 7 under the push of the extrusion piece 42.

[0027] In order to promote the movement of raw materials for producing plastic optical fibers, and at the same time, to fully mix the raw materials for producing plastic optical fibers after melting, such as Figure 6 As shown, the extrusion member 42 includes a brake rod 421, which is rotatably installed in the middle of the inner cavity of the extrusion shell 41, and the end of the brake rod 421 away from the cleaning device 7 is fixedly connected to the end face of the transmission rod in the transmission member 3. Two spiral rods 422 and two groups of spiral blades 423 are arranged on the outer surface of the brake rod 421, and the two spiral rods 422 and the two groups of spiral blades 423 are distributed at intervals. The spiral rod 422 is first arranged on the side of the outer surface of the brake rod 421 close to the transmission member 3, and the cleaning fan blade 424 is arranged on the side of the outer surface of the brake rod 421 away from the transmission member 3.

[0028] Further, such as Figure 8 and Fig. 9 As shown, the stirring mechanism 43 includes a limiting ring 431, which is rotatably installed in the inner cavity of the limiting groove 411, and a gear ring 432 is arranged on the outer side of the limiting ring 431, and the gear ring 432 is fixedly installed on the inner cavity surface of the limiting groove 411, and a plurality of stirring handles 433 are installed through the outer surface of the limiting ring 431, and the outer surfaces of the stirring handles 433 are rotatably installed on the outer surface of the brake rod 421 on the side close to each other, and the outer surfaces of the stirring handles 433 are away from the extrusion piece 42. Gears 434 are arranged on the side, and a plurality of gears 434 are meshed and connected with the gear ring 432.

[0029] Furthermore, the plurality of spiral blades 423 located in the middle are spaced apart from the stirring handles 433 in the plurality of stirring mechanisms 43 .

[0030] Furthermore, a plurality of stirring fans are provided on a side of the outer surface of the stirring handle 433 close to the brake rod 421 .

[0031] Specifically, after entering the inner cavity of the extrusion shell 41, when the brake rod 421 drives the spiral rod 422 to rotate, the spiral rod 422 can quickly push the raw material to the side of the cleaning device 7 that is close to it. During this process, the heating device 6 can melt the raw material, and then the fused raw material will be pushed by the spiral rod 422 to the area where the spiral blades 423 are located in the middle. In the process of multiple groups of spiral blades 423 rotating with the brake rod 421, the speed at which the spiral blades 423 push the raw material is lower than the speed at which the spiral rod 422 pushes the raw material. This is to give the stirring mechanism 43 time to evenly mix the raw materials.

[0032] Furthermore, in the process that the brake rod 421 drives the spiral rod 422 and the spiral blade 423 to rotate, the brake rod 421 will also drive the multiple spiral blades 423 to rotate. In the process that the spiral blades 423 rotate, the multiple gears 434 will respectively rotate with the stirring handle 433. Since the gear 434 is meshingly connected with the gear ring 432, when the gear 434 rotates with the stirring handle 433, the gear 434 will drive the stirring handle 433 to rotate. When the melted raw materials enter the area where the spiral blades 423 are located in the middle, the various substances in the raw materials can be more fully mixed through the stirring fan on the stirring handle 433.

[0033] Furthermore, the fully mixed raw materials will be pushed toward the side close to the cleaning device 7 by the screw rod 422 away from the transmission member 3 . Embodiment 2

[0034] This embodiment further improves the cleaning device 7 on the basis of the first embodiment, such as Figure 1 — Figure 3 As shown, a cleaning device 7 is provided at one end of the extrusion mechanism 4 away from the transmission member 3 , and a supporting member 8 is provided at one side of the outer surface of the heating device 6 away from the transmission member 3 .

[0035] In order to clean the impurities in the melted plastic optical fiber raw materials, such as Fig.10 and Fig.11As shown, the cleaning device 7 includes a mounting shell 71, which is fixedly mounted on one end of the extrusion shell 41 away from the transmission member 3, the inner cavity of the mounting shell 71 is communicated with the inner cavity of the extrusion shell 41, and a discharge piece 76 is provided on the side of the inner cavity of the mounting shell 71 away from the extrusion shell 41, and the discharge piece 76 extends to the outside of the mounting shell 71 away from the end of the extrusion shell 41, and a plurality of mounting cavities are opened on the outer side of the mounting shell 71, and a collection frame 72 is provided in the middle of the inner cavity of the plurality of mounting cavities, and the inner cavity of the collection frame 72 is communicated with the inner cavity of the mounting shell 71, and a circular filter plate 74 is provided in the middle of the inner cavity of the mounting shell 71, and the circular filter plate 74 is adapted for use with the cleaning blades 424, and a connecting piece 75 is provided on the outer surface of the mounting shell 71 away from the extrusion shell 41. The connecting piece 75 is communicated with the inner cavity of the mounting shell 71.

[0036] Further, such as Fig.11 As shown, the connecting member 75 includes an annular connecting frame 751, and an annular filter plate 752 is provided at one end of the annular connecting frame 751 close to the extrusion shell 41. The inner cavity of the filter hole in the annular filter plate 752 is communicated with the inner cavity of the installation cavity.

[0037] Specifically, after the evenly mixed raw material is pushed toward one side of the cleaning device 7 by the extruder 42, the raw material will first enter the inner cavity of the mounting shell 71. After the raw material enters the inner cavity of the mounting shell 71, the raw material is pushed toward the circular filter plate 74 by multiple sets of spiral blades 423 on the outer surface of the brake rod 421 away from the side of the transmission member 3.

[0038] Furthermore, when the raw material contacts the surface of the circular filter plate 74 , the circular filter plate 74 will filter the impurities in the raw material, and the raw material after passing through the circular filter plate 74 will be squeezed out of the inner cavity of the mounting shell 71 from the discharge piece 76 .

[0039] Furthermore, during the rotation of the brake rod 421, the brake rod 421 will drive the cleaning blade 424 to rotate, and the impurities filtered out by the circular filter plate 74 will remain on the surface of the circular filter plate 74. During the rotation of the cleaning blade 424, the cleaning blade 424 can clean the surface of the circular filter plate 74 to avoid more impurities from accumulating on the surface of the circular filter plate 74 and affecting the filtering efficiency of the circular filter plate 74.

[0040] Furthermore, in the process of cleaning the impurities on the surface of the circular filter plate 74 by the cleaning blades 424, the impurities will be pushed by the cleaning blades 424 toward the side away from the brake rod 421, so that the impurities enter the inner cavity of the installation cavity, and then the impurities enter the inner cavity of the corresponding collection frame 72 for collection, so that the staff can clean the impurities later.

[0041] Furthermore, in the process of the cleaning blades 424 pushing impurities into the inner cavity of the collection frame 72 for storage, the cleaning blades 424 will also cause a portion of the raw materials to be pushed into the inner cavity of the installation cavity, but this portion of the raw materials can be filtered through the annular filter plate 752 and enter the inner cavity of the annular connecting frame 751, and then pass through the inner cavity of the annular connecting frame 751 to enter the inner cavity of the installation shell 71 close to the discharge piece 76 again, and then be squeezed out of the inner cavity of the installation shell 71 through the discharge piece 76.

[0042] It should be noted that the specific installation method, circuit arrangement and connection method and control method of the motor 1 2, transmission member 3 and motor 2 53 used in the above embodiment 1 are all conventional designs in the prior art and will not be elaborated in detail in the present invention.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
