Description

Technical Field

[0001] The utility model belongs to the technical field related to optical cable production, and in particular relates to an optical fiber dot-marking stabilizing device. Background Art

[0002] With the rapid development of AI, the demand for cables in data centers is increasing. Commonly used optical cable core numbers are 2, 4, 6, 8, 12, 24, 48, 96, and 144, but the current mainstream colored optical fiber colors are 12. In order to distinguish the colors of optical cables with more than 12 cores, ink dots need to be printed on the surface of the optical fiber for distinction. Because the optical fiber jitters when it travels at high speed, the inkjet printer currently prints ink blocks. The ink blocks are larger than the optical fiber, which can ensure that the optical fiber is basically covered with ink dots, but the maximum number of ink dots printed by the inkjet printer per unit time is the same. The larger the ink block, the more ink dots are needed, and the fewer the number of prints, which makes the inkjet printer's dotting speed slow, and even reduces the maximum printing speed, increasing the failure rate of the inkjet printer. Correspondingly, the optical fiber's travel speed is also relatively slow. In order to improve production efficiency, this device is specially developed. Summary of the invention

[0003] The utility model provides an optical fiber dotting stabilizing device, which is installed below the nozzle of an inkjet printer, so that the optical fiber does not shake during high-speed travel, reduces invalid ink dots, increases the number of prints, and thus improves the dotting speed of the inkjet printer. The traveling speed of the optical fiber is also relatively increased, thereby improving production efficiency.

[0004] The technical solution adopted by the utility model is:

[0008] Preferably, a positioning column is provided on the front side of the connecting plate of the adjusting member, and a positioning through hole matching with the positioning column is provided on the bracket.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1-Figure 2 As shown, the optical fiber dot stabilizing device of the utility model comprises a T-shaped fixing seat 1 and a bracket 2 arranged on the front side of the T-shaped fixing seat 1, and mounting through holes 1-1 are opened on both sides of the T-shaped fixing seat, one end of the bracket 2 extends upward to form a first support plate 2-1, and the other end of the bracket 2 extends upward to form a second support plate 2-2, and the second support plate 2-2 is higher than the first support plate 2-1, a first guide wheel 4 is arranged in front of the first support plate 2-1 through a fixed shaft 3, and a second guide wheel 5 is arranged in front of the second support plate 2-2 through a fixed shaft 3, the first guide wheel and the second guide wheel are at the same front-to-back distance from the bracket, the upper end of the first guide wheel and the lower end of the second guide wheel are tangent to the same horizontal line, this design can ensure that the optical fiber passing through the first guide wheel and the second guide wheel is in a horizontal state, and the circumferential outer sides of the first guide wheel 4 and the second guide wheel 5 are provided with a wire passing groove 6.

[0017] When in use, the bracket is arranged at a suitable position below the inkjet printer nozzle through a T-shaped fixing seat, and the optical fiber passes from the upper part of the first guide wheel and the lower part of the second guide wheel. Under the action of the two guide wheels, the optical fiber maintains a horizontal and non-shaking state during high-speed travel. At this time, the single ink output can be set by the inkjet printer, and the single ink output can be reduced by reducing invalid ink dots, so that an ink line is printed on the optical fiber, and the width of the ink line is equal to or slightly less than the diameter of the optical fiber. It is only printed on the optical fiber, and there is basically no ink leakage; since the maximum number of ink dots printed per unit time is the same, when the single ink output is reduced, the number of printings per unit time can be increased, that is, the dotting speed of the inkjet printer is increased, and the traveling speed of the optical fiber is increased accordingly, and the production efficiency is improved; in addition, white paper can be placed in the ink box below the nozzle, and whether there is ink on the white paper can be used to judge whether all ink dots are printed on the optical fiber.

[0018] At the same time, considering that when cleaning and maintaining the nozzle, replacing the nozzle, and replacing the guide wheel, the front and back, up and down positions of the optical fiber and the nozzle will be appropriately changed. In order to make the optical fiber in the appropriate position directly below the nozzle, it is necessary to adjust the position of the first guide wheel and the second guide wheel. Specifically, an adjustment member 9 is arranged between the T-shaped fixing seat and the bracket, and a circular blind hole 1-2 is opened on the front side of the T-shaped fixing seat 1, and a first threaded through hole 1-3 connected to the circular blind hole 1-2 is opened on its side. The adjustment member 9 is composed of an adjustment guide rod 9-1 and a connecting plate 9-2 arranged on the front side of the adjustment guide rod 9-1. The adjustment guide rod 9-1 is movably arranged in the circular blind hole 1-2, and the bolt is inserted from the first threaded through hole into the circular blind hole to tighten the adjustment guide rod to achieve its fixation, thereby achieving the fixation of the connecting plate, and the bracket 2 is fixed on the front side of the connecting plate 9-2; an oblong through hole 7 is vertically opened on the first support plate, and the oblong through hole extends to the bracket, and the rear end of the fixed shaft 3 is fixed in the oblong through hole 7 by two locking nuts 8. The rear end of the fixed shaft for arranging the second guide wheel is also fixed on the first support plate by two locking nuts 8. By adjusting the rear end position of the fixed shaft, the front and rear distances of the first guide wheel and the second guide wheel and the bracket can be made the same.

[0019] When in use, the front and rear position of the optical fiber is adjusted by adjusting the position of the adjusting guide rod of the adjusting member in the circular blind hole of the T-shaped fixing seat, that is, the position of the adjusting guide rod of the adjusting member in the circular blind hole of the T-shaped fixing seat is moved forward and backward, and the positions of the first guide wheel and the second guide wheel are adjusted by controlling the front and rear position of the bracket, thereby adjusting the front and rear position of the optical fiber. The position of the adjusting guide rod of the circumferentially rotating adjusting member in the circular blind hole of the T-shaped fixing seat is adjusted to adjust the height of the first guide wheel and the second guide wheel by the circumferential rotation degree of the bracket, and then the fixed axis is used to adjust the up and down position of the first guide wheel so that it is tangent to the second guide wheel along the same straight line. At this time, the height of the optical fiber can be changed. Figure 2 As shown, rotate the bracket to the right and move the first guide wheel downward so that it is tangent to the second guide wheel along the same straight line. At this time, the height of the optical fiber is reduced; rotate the bracket to the left and move the first guide wheel upward so that it is tangent to the second guide wheel along the same straight line. At this time, the height of the optical fiber is increased.

[0020] Specifically, the bracket is fixed on the front side of the adjusting member, and the left and right sides of the connecting plate 9-2 of the adjusting member 9 are provided with second threaded through holes 10, and the bracket 2 is provided with a third threaded through hole 11 that is compatible with the second threaded through hole 10, and the bolts pass through the third threaded through hole 11 and the second threaded through hole 10 to fix the bracket.

[0021] At the same time, in order to facilitate the rapid positioning and installation of the bracket, a positioning column 12 is provided on the front side of the connecting plate 9 - 2 of the adjusting member 9 , and a positioning through hole 13 matching with the positioning column 12 is opened on the bracket 2 .

[0022] Furthermore, a conical member 3-1 is formed at the front end of the fixed shaft 3, and a limiting nut 14 is arranged at the middle thereof. The first guide wheel 4 and the second guide wheel 5 are arranged on the fixed shaft through the conical member 3-1 and the limiting nut 14, and the first guide wheel 4 can rotate in the circumferential direction. The first guide wheel and the second guide wheel are limited by the conical member and the limiting nut to avoid deviation caused by forward and backward movement.

[0023] The first guide wheel 4 and the second guide wheel 5 have the same structure, both consisting of two adjacent bearings of the same type, and the chamfers of the adjacent side surfaces of the two bearings form a V-shaped wire groove 6.

[0024] Furthermore, when the fiber dotting speed is increased, the dotting and coloring processes can be integrated to reduce the production process. At this time, the device can be placed in a suitable position on the coloring machine. The coloring process is arranged after the dotting process and needs to be cured by a UV mercury lamp. The temperature inside is high and the optical fiber cannot be in this environment for a long time. The fiber dotting process is slow. If it is the same process as the coloring, it will stay in a high temperature environment for a long time, which will affect the performance. Currently, it can only be divided into two processes. This problem can be solved after the fiber dotting speed is increased.
