Description

Technical Field

[0001] This utility model belongs to the field of optical fiber production equipment technology, and in particular relates to a cold processing and cutting device for optical fiber preforms. Background Technology

[0002] In the process of optical fiber production, cutting devices are required in the processes of slitting optical fiber preforms, fusion splicing of the tail shank before preform drawing, and removal of the head and tail taper of semi-finished preforms. In each slitting process, the quality requirements of the cut surface of the preform are quite strict. For example, if the cut surface is not flat, the quality of the tail shank fusion splicing is difficult to guarantee or even impossible to fusion.

[0003] According to a public disclosure of an optical fiber preform cutting device (publication number: CN 219621080U): it includes a worktable; it also includes a left rotation gearbox, which is located on the left side of the upper end of the worktable and is fixedly installed on the left side of the upper end of the worktable. A right rotation gearbox is located on the right side of the upper end of the worktable. Telescopic devices are provided inside the left and right rotation gearboxes and are fixedly installed inside the left and right rotation gearboxes. A telescopic rod is provided on one side of the telescopic device and is fixedly installed on one side of the telescopic device.

[0004] In the aforementioned application, the cooperation between the left speed gearbox and the telescopic device assembly makes it difficult to cool the optical fiber preform during the cutting process on the worktable. This results in the optical fiber preform reaching excessively high temperatures during the cutting process, which fails to guarantee the accuracy and material stability of the optical fiber preform. Therefore, we propose a cold-working cutting device for optical fiber preforms. Utility Model Content

Through the cooperation of components such as the motor, cooling box, and nozzle of the cooling mechanism, when cold-working cutting of optical fiber preforms is required, the operator first stabilizes and fixes the optical fiber preform, then controls the moving platform to move the cutting machine to the designated position according to the work requirements, then starts the motor to transport the coolant inside the cooling box through the nozzle, and simultaneously starts the cutting machine to perform cold-working cutting of the optical fiber preform. This design achieves the effect of cold-working cutting of optical fiber preforms, avoiding the material deformation, thermal stress, and changes in optical performance that may occur during hot cutting, maintaining the precision and material stability of the optical fiber preform, and solving existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a cold processing and cutting device for optical fiber preforms, including a processing table, a triangular clamping plate on the side of the processing table, a cutting machine on the top of the processing table, an installation box fixedly connected to the side of the processing table, and a cooling mechanism on the side of the processing table.

This design achieves the effect of cold cutting of optical fiber preforms, avoiding the material deformation, thermal stress, and changes in optical performance that may occur during hot cutting, and maintaining the precision and material stability of the optical fiber preform.

[0014] 2. This utility model utilizes the interoperability of components such as the threaded rod, scraper, and waste collection trough in the cleaning mechanism.

[0021] The top of the processing table 1 is provided with a slide groove 57, and a moving platform 58 is slidably connected inside the slide groove 57. The top of the moving platform 58 is provided with an inclined groove 59. The function of the moving platform 58 is to be adjustable for different cutting lengths.

The function of the wastewater tank 510 is to collect the coolant after use, and the function of the filter plate 511 is to isolate the waste material and waste liquid.

[0023] The number of conveyor plates 53 is set to three, and they are arranged in a circular array along the circumference of the rotating shaft 52. The three conveyor plates 53 enable the cooling box 54 to supply coolant quickly and effectively.

[0024] A cleaning mechanism 6 is provided on the side of the processing table 1. The cleaning mechanism 6 includes a threaded rod 61. One end of the threaded rod 61 is fixedly connected to the end of the rotating shaft 52 away from the output shaft of the motor 51.

The filter plate 511 separates the waste material from the waste liquid.

[0028] To prevent excessive waste accumulation from clogging the filter plate 511, the rotating shaft 52 rotates, causing the threaded rod 61 to rotate counterclockwise. The threaded sleeve 62, which is threaded to the circumferential surface of the threaded rod 61, moves from left to right. The movement of the threaded sleeve 62 drives the connecting rod 63 to move from left to right inside the moving groove 64. The movement of the connecting rod 63 drives the scraper 65 to move from left to right. During the movement of the scraper 65 from left to right, the waste on the top of the filter plate 511 is scraped and cleaned. The cleaned waste enters the waste collection groove 66 through the cleaning port 67.
