A first position adjusting assembly 5 is arranged on the fixed frame corresponding to the driving wheel assembly, a second position adjusting assembly 6 is arranged on the fixed frame corresponding to the driven wheel assembly, and a distance adjusting device 7 is arranged between the driving wheel assembly and the driven wheel assembly;
the auxiliary positioning device comprises a positioning lower guide pipe 8 and a guider 9 above the positioning lower guide pipe, and the optical fiber is guided by the guider to enter the traction equipment and then penetrate out of the positioning lower guide pipe through the driving wheel assembly and the driven wheel assembly to be drawn to move. After the waste fibers extend out of the positioning lower guide pipe, the waste fibers are aligned by the waste fiber collecting barrel for collecting and processing, and the subsequent collecting and processing process is not in the scope of the invention creation and discussion and is not repeated here.
The driving wheel assembly comprises a driving wheel mounting plate 10 and a driving wheel 11 rotatably mounted on the driving wheel mounting plate, and the driving wheel is driven to rotate by a driving mechanism 12; the driven wheel assembly includes a driven wheel mounting plate 13, and a driven wheel 14 rotatably mounted on the driven wheel mounting plate. When the structure is designed, the outer edges of the driving wheel and the driven wheel can be provided with grooves along the circumferential direction, when optical fiber traction is carried out, the grooves can limit the optical fiber to prevent the optical fiber from moving, and limit the optical fiber together with the guider and the positioning lower guide pipe to ensure the stability of optical fiber traction.
Preferably, the driving mechanism adopts a servo motor, the speed is adjustable, the servo motor is installed on a driving wheel installation plate, the driving wheel is rotatably installed on the driving wheel installation plate (through a bearing), and generally, a tensioning sleeve 31 can be adopted to connect the driving wheel and an output shaft of the servo motor. The output shaft of the servo motor is connected with the driving wheel, so that the driving wheel is driven to rotate at a required speed after the servo motor is started. Generally, the driving wheel and the driven wheel are made of aluminum alloy materials, the wheel surface is made of rubber materials, when the driving wheel and the driven wheel are clamped and rolled, large extrusion force cannot be generated on optical fibers, and the optical fibers are prevented from being broken. The wheel shaft 23 can be arranged on the driven wheel mounting plate, the driven wheel is rotatably arranged on the wheel shaft through a bearing 24, and the driving wheel can be assisted to clamp and drive the optical fiber to move in the optical fiber traction process.
The following is an improvement of a method for fiber-assisted traction using the above apparatus:
the optical fiber penetrates through the guider and then extends out of the positioning lower guide pipe, the driving wheel of the driving wheel assembly and the driven wheel of the driven wheel assembly keep clamping the optical fiber and rotate along with the driving wheel, and friction force is generated between the driving wheel (and the driven wheel) and the optical fiber, so that the driving wheel and the driven wheel form acting force for pulling the optical fiber downwards;
the change trend of the diameter of the optical fiber is judged by changing the clamping acting force of the driving wheel and the driven wheel to the optical fiber, and the pressure value is fed back to a controller in real time;
the controller controls the distance between the driving wheel and the driven wheel to be adaptively adjusted, so that the optical fiber clamping force of the driving wheel and the driven wheel is always in a certain constant range, and the phenomenon that the optical fiber is damaged due to overlarge optical fiber clamping force or the optical fiber is slipped due to undersize clamping force is avoided.
In an alternative embodiment, the distance adjusting device comprises a driving cylinder 15 arranged between the driving wheel mounting plate and the driven wheel mounting plate, and the driving wheel assembly and the driven wheel assembly are driven to be folded towards the center or unfolded outwards along the direction of the sliding rail by the contraction or extension action of an extension rod of the driving cylinder, so that the driving wheel and the driven wheel form effective clamping on the optical fiber, and the optical fiber can be pulled to extend out of the positioning downcomer under the condition that the driving wheel rotates.
Because the optical fiber external diameter that melts the in-process of drawing a silk tentatively has inhomogeneous condition, the unable self-adaptation optical fiber external diameter of conventional draw gear changes, and the clamp force appears too big or undersize, therefore, in the scheme of further improvement, set up pressure sensor on drive wheel and/or follow driving wheel, pressure sensor connects a controller, pressure sensor's pressure value feeds back to the controller in real time, by controller control actuating cylinder flexible action, the self-adaptation changes the clamp force to optical fiber, guarantee can press from both sides tight optical fiber, make drive wheel and driven wheel drive the optic fibre removal to the frictional force on optical fiber surface, can also furthest avoid the optic fibre to break.
It should be noted that the controller may be a single chip microcomputer commonly used in the prior art, and the pressure sensor may be disposed on the outer circumferential surface of the driving wheel and/or the driven wheel, for example, a patch type pressure sensor is used. Of course, the skilled person can select the type and installation form of the sensor according to the needs, as long as the clamping force variation of the driving wheel and the driven wheel to the optical fiber can be detected. When the pressure value fed back by the pressure sensor is larger than a set value, the controller controls the extension rod of the driving cylinder to extend outwards for adjustment, the distance between the driving wheel and the driven wheel is finely adjusted, and the distance between the driving wheel and the driven wheel is increased, so that the clamping force of the two wheels on the optical fiber is reduced, and the optical fiber returns to the range of normal clamping acting force. On the contrary, when the clamping acting force detected by the pressure sensor is smaller than the set value, the distance between the driving wheel and the driven wheel is reduced through the controller.
When the driving mechanism adopts a servo motor, the servo motor can be electrically connected with the controller, when the diameter of the optical fiber changes, the controller can send an instruction to control the speed of the servo motor to adjust after receiving the signal feedback of the pressure sensor, for example, when the pressure value fed back by the pressure sensor is reduced, the diameter of the optical fiber is reduced, at the moment, the controller sends an instruction to reduce the rotating speed of the servo motor, further, the rotating speed of the driving wheel is reduced, the purpose of reducing the moving speed of the traction optical fiber is finally achieved, and the optical fiber is prevented from being broken to the maximum extent. On the contrary, when the pressure value fed back by the pressure sensor is increased, the diameter of the optical fiber is increased, at the moment, the controller sends an instruction to control the interval adjusting device to act, and simultaneously controls the rotating speed of the driving wheel to increase. Compared with the traditional traction tool, the auxiliary traction equipment can be used for earlier intervention, namely, the auxiliary traction equipment can be used for traction movement when the optical fiber basically meets the traction requirement, so that the production efficiency is effectively improved, and meanwhile, the optical fiber is prevented from being broken to the maximum extent.

After the optical fiber perform is placed into the drawing furnace, the drawing furnace heats up the taper head of the induction heating perform, after a period of time, the taper head of the perform melts and falls, and the outlet of the extending pipe at the bottom of the furnace falls. The cone head melted at the initial stage is large and uneven, and the worker cuts the cone through a corresponding tool at the moment. When the diameter of the optical fiber coming out of the furnace extension pipe basically meets the requirements of the traction process, the optical fiber can fall down under the action of gravity, and an operator sequentially penetrates the optical fiber through the diameter measuring instrument and the cooling pipe to reach the auxiliary traction device. Compared with the traditional traction tool, the equipment can be inserted earlier, and the production efficiency is effectively improved.
The optical fiber passes through the guide gap between the two upper guide rods and extends out through the positioning lower guide pipe, so that the optical fiber can be prevented from being separated from the wheel surface in the clamping process. The driving wheel assembly and the driven wheel assembly are driven to fold towards the center along the direction of the sliding rail through the distance adjusting device, so that the driven wheel and the driving wheel clamp the optical fiber, meanwhile, the servo driver gives out an initial speed to drive the driving wheel to rotate, the driven wheel and the driving wheel roll downwards in opposite directions, the optical fiber extends out along the positioning lower guide pipe, an operator puts waste optical fiber into a collecting barrel, after the optical fiber meets the process requirements, the driving wheel and the driven wheel of the device are loosened, and the optical fiber penetrates through a coating device die to carry out the next operation.
