Description

Technical Field

[0001] The invention relates to the technical field of optical fiber production, and in particular to an auxiliary optical fiber upper disk pulling device and an optical fiber production line. Background Art

[0002] In the production process of optical fiber, the optical fiber mother material is processed into a filament by a heating device, and then drawn into a finished optical fiber under the main traction action. The optical fiber passes through various auxiliary guide wheels and is finally wound on the optical fiber take-up reel.

[0003] At present, in the early stage of production, the optical fiber head pulled out by the main traction mechanism must first be manually wound around each auxiliary guide wheel and the take-up reel, and finally the take-up device will automatically wind the optical fiber onto the take-up reel to complete the winding operation. Because the main traction mechanism pulls out the optical fiber at a certain speed, in order to smoothly wind the optical fiber around each auxiliary guide wheel, the optical fiber must be manually pulled to maintain the same output speed as the main traction mechanism so that the optical fiber is in a taut state, otherwise the optical fiber will be loosely accumulated and slip out, resulting in a failure in winding. Sometimes during the optical fiber production process, the optical fiber will accumulate between the main traction mechanism and the auxiliary guide wheel, and the manual winding operation as described above is also required. Moreover, for the optical fiber in a piled-up state generated during the optical fiber production, it is necessary to pull the accumulated optical fiber at a faster speed than the main traction mechanism to make the optical fiber return to a taut state.

[0004] The success rate of manual reeling is low, resulting in low work efficiency. A large amount of optical fiber is pulled out and becomes waste, wasting a lot of manpower and material resources.

[0005] Based on this, there is an urgent need for an auxiliary optical fiber upper disk pulling device and an optical fiber production line to solve the above-mentioned problems. Summary of the invention

[0033] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] like Figure 1 As shown, the optical fiber production line includes a heating device 101, an optical fiber mother material 102, a main traction mechanism 103, an auxiliary guide wheel 104 and a take-up reel 105. The optical fiber mother material 102 passes through the heating device 101 and is drawn into an optical fiber 3. The main traction mechanism 103 continuously pulls the optical fiber 3 outward at a certain speed. The optical fiber 3 passes through the auxiliary guide wheel 104 and is finally wound on the take-up reel 105. In the production process, there are roughly two situations where the optical fiber 3 needs to be wound:

[0038] The first case is the initial stage of production of optical fiber 3. The processed optical fiber 3 is continuously pulled out at a certain speed by the main pulling mechanism 103. At this time, the optical fiber head of the optical fiber 3 between the main pulling mechanism 103 and the auxiliary guide wheel 104 needs to be pulled at the same speed as the main pulling mechanism 103 and bypass the auxiliary guide wheel 104, so that the optical fiber 3 is in a taut state on the production line and fixed on the take-up reel 105 to complete the winding.

[0039] The second situation is when the optical fiber 3 is produced. Figure 2 As shown, the optical fiber 3 is piled up between the main traction mechanism 103 and the auxiliary guide wheel 104. At this time, it is necessary to pull the end of the piled optical fiber 3 close to the main traction mechanism 103 at the same speed as the main traction mechanism 103 and wind it around the auxiliary guide wheel 104, so that the optical fiber 3 is in a taut state on the production line, fixed on the take-up reel 105 to complete the winding, and remove the previously piled optical fiber 3.

[0040] This embodiment provides an auxiliary optical fiber winding pulling device, which is used to assist the winding of the optical fiber 3. At present, the optical fiber 3 is wound manually, but the manual winding success rate is low, resulting in low work efficiency, a large number of optical fibers 3 are pulled out and become waste, and a lot of manpower and material resources are wasted.

[0041] To solve the above problems, the present embodiment provides an auxiliary optical fiber mounting traction device, which is used to assist optical fiber mounting, improve the mounting success rate, and reduce optical fiber waste. The auxiliary optical fiber mounting traction device includes a traction unit 1 for traction of optical fiber 3 and a storage unit for storage of optical fiber 3.

[0042] Specifically, Figure 3 As shown, the traction unit 1 includes a variable speed traction component 12 and a variable pressure component 11. The variable speed traction component 12 is used to pull the optical fiber 3 and adjust the speed of pulling the optical fiber 3. The pressure output end of the variable pressure component 11 is connected to the variable speed traction component 12, and the variable pressure component 11 is used to adjust the pressing force of the variable speed traction component 12 on the optical fiber 3. The speed of traction of the optical fiber 3 is adjusted by the variable speed traction component 12, which is suitable for various speed requirements of winding up the optical fiber 3. The pressing force of the variable speed traction component 12 on the optical fiber 3 is changed by the variable pressure component 11, so as to adjust the number of optical fibers 3 passing through the traction unit 1 according to the demand. This device simplifies the operation of traditional manual winding, saves a lot of manpower and material resources, adapts to various scenarios of winding the optical fiber 3, and greatly improves the success rate of winding, reduces production costs, and increases work efficiency.

[0043] Preferably, a housing 2 is provided outside the traction unit 1, and a take-up opening 4 is provided on the housing 2, and the optical fiber 3 extends into the traction unit 1 through the take-up opening 4. Specifically, the take-up opening 4 extends outside the housing 2, and one end of the take-up opening 4 outside the housing 2 is in an outwardly expanding trumpet shape, and the trumpet-shaped take-up opening 4 is easier to put in the optical fiber 3, and easier to collect the accumulated optical fiber 3, thereby increasing the practicality of the device.

[0044] Preferably, the storage unit includes a storage box 51, which is connected to the housing 2. The storage box 51 is used to place the optical fiber 3 pulled into the device to prevent the optical fiber 3 from falling, avoid interfering with the optical fiber 3 at other positions, and increase the practicality of the device.

[0045] Preferably, the variable speed traction assembly 12 includes a driving wheel 121 and a driven wheel 122. When the optical fiber 3 is placed between the driving wheel 121 and the driven wheel 122, the driving wheel 121 and the driven wheel 122 are both pressed against the optical fiber 3. The driving wheel 121 is connected to a variable speed drive, and the driving wheel 121 drives the driven wheel 122 to rotate at the same speed in opposite directions. The speed of the driving wheel 121 and the driven wheel 122 pulling the optical fiber 3 is adjusted by the variable speed drive to meet different optical fiber 3 pulling speed requirements, thereby improving the practicality of the device.

[0046] In this embodiment, the driving wheel 121 and the driven wheel 122 are coated with a soft material with a large friction coefficient to increase the friction between the driving wheel 121, the driven wheel 122 and the optical fiber 3, so that the optical fiber 3 is not easy to slip when being pulled.

[0047] Specifically, in this embodiment, the variable speed drive is used to change the speed of pulling the optical fiber 3, and the variable speed drive includes a drive motor 123 and a speed regulator. The output end of the drive motor 123 is connected to the rotating shaft of the driving wheel 121, and the speed regulator is used to control and adjust the speed of the drive motor 123, change the speed of pulling the optical fiber 3, so that the device meets different optical fiber 3 pulling speed requirements, and improves the practicality of the device.

[0048] In other embodiments, the speed-changing drive member may be other mechanisms capable of adjusting the pulling speed of the optical fiber 3 , which is not limited here.

[0049] Preferably, the variable pressure assembly 11 is used to change the pressing force of the variable speed traction assembly 12 on the optical fiber 3, and the variable pressure assembly 11 includes a pressing member 111. One end of the pressing member 111 is connected to the driven wheel 122, and the other end is connected to the adjusting member 112. The adjusting member 112 is used to press the driven wheel 122 toward the driving wheel 121 through the pressing member 111 and change the pressing force between the driven wheel 122 and the driving wheel 121. That is, when the optical fiber 3 is placed between the driving wheel 121 and the driven wheel 122, the adjusting member 112 is used to press the driven wheel 122 toward the driving wheel 121 through the pressing member 111 and change the pressing force on the optical fiber 3. By changing the pressing force of the driving wheel 121 and the driven wheel 122 on the optical fiber 3 through the pressing member 111, the number of optical fibers 3 passing through the traction unit 1 can be adjusted according to demand, and the optical fiber 3 can be prevented from derailing, which is suitable for various scenarios of optical fiber 3 on the disk, thereby increasing work efficiency.

[0050] In this embodiment, the pressing member 111 is a spring, and the force exerted by the spring on the driven wheel 122 is pressure. The adjusting member 112 is an adjustment button capable of adjusting the length of the spring. Figure 4 As shown, when multiple optical fibers need to pass between the driving wheel 121 and the driven wheel 122, the adjustment button is adjusted to reduce the compression of the spring, so that the pressure of the spring on the driven wheel 122 becomes smaller, so that the pressing force between the driving wheel 121 and the driven wheel 122 on the optical fiber 3 becomes smaller, allowing multiple optical fibers 3 to pass between the driving wheel 121 and the driven wheel 122. Figure 5 As shown, when a single optical fiber 3 needs to pass between the driving wheel 121 and the driven wheel 122, the adjustment button is adjusted to increase the compression of the spring, and the pressure of the spring on the driven wheel 122 becomes larger, so that the pressing force between the driving wheel 121 and the driven wheel 122 on the optical fiber 3 becomes larger, and multiple optical fibers 3 are prevented from passing between the driving wheel 121 and the driven wheel 122. The device is adapted to various scenarios of optical fiber 3 on the disk, and the work efficiency is improved. The spring is an elastic member, so that the number of optical fibers 3 passing between the driving wheel 121 and the driven wheel 122 can be adaptively adjusted within a certain range, and the optical fiber 3 is ensured not to derail, thereby improving the practicality of the device.

[0051] In other embodiments, the clamping member 111 also includes a rod, and the clamping force applied by the rod to the optical fiber 3 between the driving wheel 121 and the driven wheel 122 is adjusted by the adjustment member 112, so as to adjust the number of optical fibers 3 allowed to pass between the driving wheel 121 and the driven wheel 122, so that the device can adapt to various scenarios of optical fiber 3 being put on the disk, thereby increasing work efficiency.

[0052] In other embodiments, preferably, the variable pressure assembly 11 includes a cylinder, a piston rod of the cylinder is connected to the driven wheel 122, and the cylinder drives the driven wheel 122 to press against the driving wheel 121. That is, when the optical fiber 3 is placed between the driving wheel 121 and the driven wheel 122, the cylinder drives the driven wheel 122 to press the optical fiber 3 against the driving wheel 121. The pressure of the cylinder piston rod on the driven wheel 122 is adjusted according to the number of optical fibers 3 that need to pass between the driving wheel 121 and the driven wheel 122, so that the device can adapt to various scenarios of optical fiber 3 on the disk, thereby increasing work efficiency.

[0053] For ease of understanding, the use process of the auxiliary optical fiber upper disk pulling device provided in this embodiment in the two situations of the initial stage of optical fiber production and the accumulation of optical fibers on the production line is as follows:

[0054] Scenario 1: Early stage of optical fiber production:

[0055] First, before the production of the optical fiber 3, the pressure of the spring on the driven wheel 122 is adjusted so that one optical fiber 3 is allowed to pass between the driving wheel 121 and the driven wheel 122.

[0056] Secondly, the driving motor 123 is turned on and the speed regulator is adjusted so that the driving motor 123 drives the driving wheel 121 and the driven wheel 122 to pull the optical fiber 3 at a speed slightly lower than the speed at which the main pulling mechanism 103 pulls out the optical fiber 3 .

[0057] Again, after the production of optical fiber 3 begins, the optical fiber head of the optical fiber 3 pulled out by the main traction mechanism 103 is extended into the traction unit 1 through the take-up port 4, and the auxiliary optical fiber upper disk traction device is moved at a certain speed to ensure that the speed at which the optical fiber 3 is pulled is basically the same as the traction and pulling speed of the main traction mechanism 103.

[0058] Finally, the optical fiber 3 is kept in a taut state, and the auxiliary optical fiber winding traction device is moved to draw the optical fiber 3 around the auxiliary guide wheel 104 and the take-up reel 105 in sequence to complete the winding.

[0059] Scenario 2: Optical fiber piles up on the production line:

[0060] First, the pressure of the spring on the driven wheel 122 is adjusted so that a plurality of optical fibers 3 are allowed to pass through between the driving wheel 121 and the driven wheel 122 .

[0061] Secondly, the driving motor 123 is turned on and the speed regulator is adjusted so that the driving motor 123 drives the driving wheel 121 and the driven wheel 122 to pull the optical fiber 3 at a speed slightly greater than the speed at which the main pulling mechanism 103 pulls out the optical fiber 3 .

[0062] Next, the take-up opening 4 of the accumulated optical fiber 3 is extended into the traction unit 1 to ensure that the speed at which the optical fiber 3 is pulled is slightly faster than the pulling and pulling speed of the main traction mechanism 103 .

[0063] Then, after the optical fibers 3 to be stacked are basically stored in the storage box 51, the pressure of the spring on the driven wheel 122 is adjusted to allow one optical fiber 3 to pass between the driving wheel 121 and the driven wheel 122. The speed regulator is adjusted to make the speed at which the driving motor 123 drives the driving wheel 121 and the driven wheel 122 to pull the optical fiber 3 slightly lower than the speed at which the main pulling mechanism 103 pulls out the optical fiber 3.

[0064] Finally, the auxiliary optical fiber winding traction device is moved at a certain speed to ensure that the speed of the optical fiber 3 being drawn is substantially the same as the pulling speed of the main pulling mechanism 103, so that the optical fiber 3 is kept in a taut state. The auxiliary optical fiber winding traction device is moved to pull the optical fiber 3 around the auxiliary guide wheel 104 and the take-up reel 105 in sequence to complete winding.

[0065] This embodiment also provides an optical fiber production line, including the auxiliary optical fiber reeling traction device mentioned above, which improves the success rate and efficiency of optical fiber reeling and saves production costs.

[0066] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
