[0038] Reference Figs. 1-2 The cutting mechanism of the first aspect embodiment of the present application is applied in the field of optical element manufacturing, mainly relates to the cutting of optical fiber glass filaments in the optical fiber glass filament drawing process of optical fiber image transmission elements, and the cutting mechanism comprises a cutting component 100, a bellows component 200 and a filtering component 300.

[0039] The bellows component 200 comprises a first inlet 211 and a first outlet 212, and the bellows component 200 is used to generate negative pressure. The first inlet 211 can communicate with the inside of the cutting component 100, so that the air in the cutting component 100 can be discharged from the first outlet 212 through the bellows component 200. The filtering component 300 is arranged between the first inlet 211 and the cutting component 100, and the filtering component 300 is used to filter and retain the dust in the air.

[0040] It can be understood that the glass slag and dust generated during the cutting of the optical fiber glass filaments are timely sucked and removed by the bellows component 200, and the glass slag and dust are retained by the filtering component 300, so as to improve the surface quality of the optical fiber glass filaments, and finally improve the finished product quality of the optical fiber image transmission elements.

[0041] It should be noted that the cutting component is used to cut the optical fiber glass wire, and glass slag and dust will be generated during cutting. Based on the negative pressure effect of the bellows component 200, air is drawn away from the cutting component together with the glass slag and dust, and then flows through the filtering component 300. The filtering component 300 retains the glass slag and dust, and the air continues to flow to the bellows component 200 and is finally discharged from the first outlet 212, thereby ensuring the surface quality of the optical fiber glass wire.

[0042] In some embodiments of the present application, the filtering component 300 includes a dust collecting barrel 310 and a filter core 320, and the filter core 320 is arranged in the dust collecting barrel 310. The filter core 320 is used to filter dust in the air in the dust collecting barrel 310. It can be understood that the filter core 320 is used to filter the glass slag and dust, so that the glass slag and dust can be retained as much as possible in the dust collecting barrel 310 without flowing to the bellows component 200 after passing through the filter core 320. Specifically, the filter core 320 is arranged across the flow path of the glass slag, dust and air, so as to retain the glass slag and dust while the air flows smoothly.

[0043] In some embodiments, the dust collecting barrel 310 and the filter core 320 are detachably connected, on the one hand to facilitate replacement of the filter core 320, and on the other hand to facilitate disposal of the glass slag and dust retained in the dust collecting barrel 310.

[0044] In order to enable the first inlet 211 to communicate with the inside of the cutting component 100, and the filtering component 300 is arranged between the first inlet 211 and the cutting component 100, in some embodiments of the present application, the cutting mechanism further includes a first pipe 400 and a second pipe 500, the dust collecting barrel 310 includes a second inlet and a second outlet, one end of the first pipe 400 is communicated to the inside of the cutting component 100, the other end of the first pipe 400 is connected to the second inlet, one end of the second pipe 500 is connected to the second outlet, and the other end of the second pipe 500 is connected to the first inlet 211.

[0045] It can be understood that by arranging the first pipe 400 and the second pipe 500, a flow channel is formed among the cutting component 100, the filtering component 300 and the bellows component 200. The air and dust flow in the first pipe 400, the air flows in the second pipe 500 and the bellows component 200 after being filtered by the filtering component 300, and is discharged from the first outlet 212.

[0046] In some embodiments, the first outlet 212 can be provided with an exhaust pipe to discharge air to a specific location to ensure the working environment.

[0047] In some embodiments of this application, a noise-reducing exhaust duct 600 is provided at the first outlet 212. It is understood that by setting the exhaust duct as a noise-reducing exhaust duct 600, noise reduction is achieved in addition to exhausting air to a specific location, thereby further purifying the working environment.

[0048] In some embodiments, the above-mentioned settings can effectively remove the vast majority of glass fragments and glass dust smaller than 150μm, with a dust particle removal rate of 97.57% for particles with a diameter of 150μm and smaller. This can effectively improve the surface quality of the optical fiber and have a positive impact on the finished product quality of optical fiber imaging components.

[0049] In some embodiments of this application, the cutting component 100 includes a fixed cutter 110, a movable cutter 120, and a housing 130. The fixed cutter 110 and the movable cutter 120 are disposed within the housing 130 and are used to cut optical fiber glass filaments. The housing 130 is provided with an intake port 131, which is used to connect to the first inlet 211. It can be understood that the housing 130 serves as a supporting foundation, used to house components such as the fixed cutter 110 and the movable cutter 120, and also to initially confine dust within the space of the housing 130, so that dust and glass shards can be promptly drawn out by negative pressure and filtered by the filter component 300. When the fixed cutter 110 and the movable cutter 120 move relative to each other, the optical fiber glass filaments between them are cut by the force of the fixed cutter 110 and the movable cutter 120, thereby achieving the cutting effect.

[0050] In some embodiments, the movable cutter 120 is connected to a drive assembly, and the fixed cutter 110 and the movable cutter 120 are arranged opposite to each other. The drive assembly drives the fixed cutter 110 to move linearly so as to cut the optical fiber glass filament.

[0051] In some embodiments of this application, the cutting component 100 includes an electromagnet drive 140, which drives the movable cutter 120 to move relative to the fixed cutter 110 to cut the optical fiber glass filament. It is understood that using the electromagnet drive 140 to drive the movable cutter 120 can effectively achieve the effect of cutting the optical fiber glass filament. The electromagnet drive 140 includes an electromagnet, which provides the driving force to drive the movable cutter 120.

[0052] In some embodiments of this application, the bellows component 200 includes a housing 210 and a negative pressure assembly 220. The negative pressure assembly 220 is disposed within the housing 210 and is used to generate negative pressure. It is understood that the inner cavity of the housing 210 is used to house the negative pressure assembly 220 and to ensure that the negative pressure generated by the negative pressure assembly 220 acts smoothly on the cutting component 100, so that after the cutting component 100 cuts the optical fiber glass filament, the dust and glass shards carried by the surrounding air can be smoothly drawn away by the negative pressure and discharged through the housing 210 from the first outlet 212.

[0053] In some embodiments, the first inlet 211 and the first outlet 212 are formed in the box 210, and the negative pressure assembly 220 includes a motor or other component capable of generating a negative pressure effect.

[0054] In order to effectively prevent the noise from spreading through the four walls of the air bellow, in some embodiments of the present application, the air bellow component 200 includes a soundproofing material layer 230 arranged on the inner wall of the box 210.

[0055] In some embodiments, the soundproofing material layer 230 can be composed of soundproofing cotton or other soundproofing materials.

[0056] In some embodiments of the present application, the main body is composed of a dust removal device and a cutting mechanism. The main body of the dust removal device is composed of an air bellow, an exhaust pipe, a dust collecting barrel 310 and a wind pipe. The air bellow is composed of a motor and soundproofing cotton, and the fan is fixed on the air bellow. Six pieces of soundproofing cotton are respectively adhered to the six walls of the air bellow, so that the inner wall of the air bellow is completely covered by the soundproofing cotton.

[0057] The cutting mechanism is composed of a fixed cutter 110, a movable cutter 120 and a box body 130. The working principle of the cutting mechanism is that the movable cutter 120 is driven by an electromagnet to collide with the optical fiber glass wire, and the optical fiber glass wire collides with the fixed cutter 110, so that the optical fiber glass wire is broken.

[0058] The working principle of the dust removal device is mainly based on the principle of pressure. During work, the air in the air bellow is sucked away through the inlet of the motor by high-speed rotation of the motor, so that the air bellow generates a negative pressure (i.e. a certain vacuum). Due to the effect of atmospheric pressure, the glass debris and dust are pushed into the suction inlet 131 by the external atmospheric pressure, enter the dust collecting barrel 310 through the wind pipe, and are filtered out by the filter element 320 after being sucked into the glass debris and dust. The glass debris and dust are left in the dust collecting barrel 310, and the air enters the motor and is discharged through the air outlet of the dust removal device. In this way, the dust removal device completes a working cycle.

[0059] In addition, the present application has a noise reduction technology, which is composed of two noise reduction methods of using a noise reduction exhaust pipe 600 and placing soundproofing cotton. The noise reduction exhaust pipe 600 effectively prevents the noise from spreading through the air outlet, and the soundproofing cotton wraps the inner wall of the air bellow, effectively preventing the noise from spreading through the four walls of the air bellow. The combination of the noise reduction exhaust pipe 600 and the soundproofing cotton can significantly reduce the noise generated by the dust removal device.

[0060] In actual production, the on-line cutting mechanism with dust removal function of the optical fiber drawing machine is installed on the drawing machine frame 700. When the cutting mechanism works, the dust removal device is started synchronously. The glass slag and dust generated in the cutting process will be sucked into the suction inlet 131 and then collected into the dust collecting barrel 310. After the air is filtered by the filter core 320, it will finally be discharged from the air outlet.

[0061] The optical fiber drawing device of the second aspect embodiment of the present application can be an optical fiber glass filament manufacturing device of an optical fiber image transmission element. The optical fiber drawing device includes the cutting mechanism of the first aspect embodiment of the present application, which can timely suck away the glass slag and dust generated in the cutting process of the optical fiber glass filament, thereby improving the surface quality of the optical fiber glass filament.

[0062] The production line of the third aspect embodiment of the present application can be a production line of an optical fiber image transmission element. The production line includes the optical fiber drawing device of the second aspect embodiment of the present application, which can improve the finished product quality of the optical fiber image transmission element.

[0063] It is not difficult to understand that the optical fiber drawing device in the second aspect embodiment of the present application and the production line in the third aspect embodiment of the present application both have the technical effects of the cutting mechanism in the first aspect embodiment as described above, and thus will not be described again.

[0064] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0065] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present application.
