Example one
Referring to fig. 1, the present embodiment provides a tool for cleaning an optical fiber drawing channel, which includes an outer cylinder 11, an inner cylinder 12, an upper ring plate 13, and a lower ring plate 14.
Wherein, the outer cylinder 11 is provided with at least two interfaces 111, the interfaces 111 are suitable for being externally connected with the negative pressure mechanism 3, and all the interfaces 111 are uniformly distributed along the circumferential direction of the outer cylinder 11. The main function of the interface 111 is to connect with the negative pressure mechanism 3 to form an air flow in use. The shape of the interface 111 is not limited herein, and may be circular or square or other common shapes, depending on the shape of the joint of the negative pressure mechanism 3. The arrangement form of the interface 111 may be only one circle in the axial direction of the outer cylinder 11, or two or more circles along the axial direction of the outer cylinder 11, but each circle needs to be uniformly distributed along the circumferential direction of the outer cylinder 11 to ensure that the adsorption force applied to the optical fiber in the circumferential direction is uniform, so as to avoid the optical fiber from horizontally shaking. The shape of the outer cylinder 11 is not limited here, and can be a cylinder, a square cylinder or other polygonal cylinders, preferably a cylinder, which is more convenient to process and install, and the formed dust exhaust channel is smooth transition at all places in the circumferential direction, so that dust can be prevented from staying at corners.
Wherein, the inner side of the inner cylinder 12 forms a through cavity suitable for the optical fiber to pass through, the inner cylinder 12 is coaxially arranged in the outer cylinder 11 and is arranged with the outer cylinder 11 at intervals to form a dust exhaust channel with an annular section, and the inner cylinder 12 is uniformly distributed with air holes 121. The through cavity is a cavity with both upper and lower ends open. The shape of the air hole 121 is not limited herein, and may be a circular hole or a square hole or other common shapes; the opening of the air holes 121 is not limited, and may be a straight hole or an inclined hole perpendicular to the surface of the inner cylinder 12. The main function of the dust exhaust channel is to ensure the adsorption effect and improve the practicability of the device; if the dust exhaust channel is removed, the plurality of interfaces 111 are directly arranged on the inner cylinder 12, and in order to ensure the adsorption effect, a plurality of interfaces 111 need to be uniformly distributed on the wall of the inner cylinder 12 corresponding to the optical fiber, and the plurality of interfaces 111 are simultaneously connected with the negative pressure mechanism 3, which causes the connection complexity; through the setting of dust exhaust passageway, can guarantee absorbent effect through the hole, guarantee the convenience of connecting through interface 111 simultaneously. When the annealing dust removal device is used, the annealed optical fibers enter the through cavity, dust on the optical fibers is adsorbed outwards under the action of air flow and enters the dust removal channel through the air holes 121.
Wherein, the upper ring plate 13 covers the upper end surface of the dust exhaust channel in a sealing way, and the lower ring plate 14 covers the lower end surface of the dust exhaust channel in a sealing way. The sealing can be realized by conventional sealing means such as a sealant or a gasket, and can also be realized by integrally forming the upper ring plate 13, the lower ring plate 14, the inner cylinder 12 and the outer cylinder 11 from the structural point of view. The sealing is mainly used for ensuring that dust does not leak to workshops to cause pollution and ensuring the adsorption force to the dust, and if the upper part and the lower part are open, the air flow can be sucked from the upper end and the lower end at the same time, so that the adsorption force of the air flow passing through the air holes 121 is reduced, and the adsorption effect is influenced.

Moreover, dust on the optical fiber can be intensively treated through the air holes 121, the exhaust channel and the interface 111 under the action of adsorption force and cannot be emitted to a workshop, so that the pollution to the workshop is avoided.
In a preferred embodiment of the above-mentioned structure, the ports 111 are all located on the same axial cross section of the outer tube 11, and the axial cross section is located at the middle position in the axial direction of the outer tube 11. The number of the interfaces 111 may be two or three or more, and preferably two interfaces are provided, that is, two interfaces can ensure the uniformity of the adsorption force, and the connection with the external negative pressure mechanism 3 is also convenient. The interface 111 is provided at an intermediate position in the axial direction of the outer cylinder 11, and it is possible to avoid the occurrence of an excessively small local adsorption force of the optical fiber due to an excessive position of the interface 111.
As a preferable mode of the above, the air holes 121 located at both sides of the axial cross section are inclined holes and are symmetrically arranged with respect to the axial cross section, and the air holes 121 are inclined from the inside to the outside in a direction close to the axial cross section. The trend that axial cross section both sides gas pocket 121 formed and assembled from inside to outside for directly get into interface 111 after the dust assembles, such structure does benefit to the collection of dust, can avoid to a certain extent that partial dust stops to cause the accumulation in the dust exhaust passageway. Further preferably, the inclination angle of the air hole 121 is 45 degrees. Of course, in other embodiments, the inclination angle of the air hole 121 may also be 30 degrees or 60 degrees.
As the improvement scheme of the above scheme, the tool 1 further comprises a dust collecting funnel, and the small-diameter end of the dust collecting funnel is fixed on the upper ring plate 13. The main function of the dust collecting funnel is to gather and guide the dust, so that the dust can smoothly enter the through cavity. A funnel and a conical structure with a large port and a small port. The smaller diameter end of the collection funnel is secured to the upper ring plate 13 and may be aligned with the inner edge of the upper ring plate 13, or with the outer edge of the upper ring plate 13, or between the inner and outer edges of the upper ring plate 13.
Preferably, the diameter of the small diameter end of the dust collecting funnel is equal to the diameter of the outer cylinder 11, and the upper ring plate 13 is provided with dust leakage holes 131. The dust leakage hole 131 is communicated with the dust exhaust passage, and a negative pressure is formed at the position, so that the dust in the dust collection funnel is sucked into the dust exhaust passage through the dust leakage hole 131 and then discharged from the interface 111.
Based on the above specific embodiment, the use process of the tool for cleaning the optical fiber drawing channel of the embodiment is as follows:
firstly, the whole tool 1 is arranged below an annealing pipe, so that the tool is coaxial with the annealing pipe, and a dust collecting funnel faces to the bottom of the annealing pipe; then, the interface 111 is connected with an external negative pressure mechanism 3 to generate negative pressure; the annealed optical fiber falls into the through hole of the inner barrel 12, and due to the action of negative pressure, uniform adsorption force is generated on the circumferential direction of the optical fiber, so that dust on the surface of the optical fiber is sucked away and is discharged after passing through the air hole 121, the dust discharge channel and the interface 111 in sequence.

Wherein the filter mechanism 4 is communicated with the output port of the negative pressure mechanism 3 and is suitable for filtering dust in the airflow. The filtering mechanism 4 can be a common structure such as a filter screen, filter cotton and the like.
Wherein, the controller 5 is connected with the wire diameter gauge 2 and the negative pressure mechanism 3 and is suitable for controlling the negative pressure mechanism 3 to be started when the wire diameter gauge 2 detects the diameter of the optical fiber and the diameter of the optical fiber continuously changes. The controller 5 is preferably a PLC, which is a function of simply receiving a signal, determining a signal, and transmitting a control command.
