Description
Technical Field
[0001] The utility model belongs to the technical field related to optical cable production, and particularly relates to an optical cable printing auxiliary device. Background Art
[0002] During the optical cable production process, before the cable is reeled, it is necessary to print labels on the cable surface, such as the product model and manufacturer's trademark. Alternatively, the cable may be printed to meet customer requirements. Printing is typically done at regular intervals. Currently, the main methods for printing on the cable surface include inkjet printing, inkjet printer printing, ribbon printing, hot stamping, and laser printing.
[0003] Indoor optical cables are typically printed using inkjet printers, which spray ink directly onto the cable surface. This approach offers low cost and high efficiency, allowing for flexible adjustment of print content and font size. The print quality is clear and aesthetically pleasing. However, the only drawback is poor adhesion, which can easily cause printed content to wear out. To address this issue, plasma equipment is typically placed in front of the inkjet printer. After plasma treatment, the printed ink on the cable's surface penetrates the sheath, imparting excellent wear resistance and making it difficult to erase. Currently, when plasma equipment is deployed, the spray gun must be positioned a certain distance from the printer's nozzle. Due to the high speed of the optical cable, the cable may shift as it travels from the plasma spray gun to beneath the printer's nozzle. This can cause the cable to shift after plasma treatment, affecting the printing quality. Summary of the Invention

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] The optical cable printing auxiliary device of the present invention includes a bracket 1 and a workbench 2 arranged on the top of the bracket 1, and an inverted trapezoidal groove 4 is opened on the top of the workbench; a clamping device 3 is provided on the top right side of the workbench 2, and the clamping device 3 includes a base plate 31 fixed to the top right side of the workbench 2, and two vertical plates 32 are provided in front and behind the base plate 31, and two conveying rollers 9 are provided between the two vertical plates, and both conveying rollers 9 are rotatable, and the conveying rollers 9 located on the upper part can move up and down; a first L-shaped plate 5 is provided on the rear left side of the top of the base plate 31, and a first wire pulley 6 is arranged on the front side of the first L-shaped plate 5 through a fixed axis, and a second L-shaped plate 7 is arranged on the rear right side of the top of the workbench 2, and a second wire pulley 8 is provided on the front side of the second L-shaped plate 7 through a fixed axis, and the first wire pulley 6 and the second wire pulley 8 are both rotatable, and their circumferential outer sides have a wire groove.
[0021] During use, the auxiliary device is positioned in front of the inkjet printer's printhead, between the first and second guide pulleys, and directly above the optical cable. The plasma equipment's spray gun is positioned to the right of the auxiliary device, with its nozzle aligned with the top of the optical cable. The optical cable passes horizontally from right to left, between the two conveyor rollers of the compression device, below the first guide pulley, and above the second guide pulley. After plasma treatment, the cable is properly compressed and conveyed by the two conveyor rollers to prevent it from flipping. It is further conveyed stably by the two guide pulleys, ensuring that the plasma-treated cable can move forward stably and align with the inkjet printer's printhead. The position of the top conveyor roller is adjusted according to the cable's diameter, ensuring that the two conveyor rollers can properly compress and clamp the cable to prevent it from flipping. This is particularly effective when used with flat-pack optical cables.
[0022] In this embodiment, the upper conveyor roller moves up and down in this manner. The two vertical plates 31 are provided with vertical through-slots extending through their front and rear sides. The through-slots have limiting slots 33 formed on their opposing inner walls. Limiting blocks 34 are disposed within the through-slots, cooperating with the limiting slots 33. The upper conveyor roller 9 is positioned between the two limiting blocks 34, with a cross plate 35 positioned atop the two limiting blocks 34. A horizontal plate 36 is disposed atop the two vertical plates. A screw 37 is vertically mounted on the horizontal plate 36. A handwheel 38 is disposed at the upper end of the screw 37, and the lower end of the screw 37 passes through the horizontal plate 36 and is positioned on the cross plate 35. The screw is rotated by the handwheel, moving upward or downward, driving the cross plate atop the limiting blocks to move up and down, thereby driving the upper conveyor roller up and down, moving away from or closer to the lower conveyor roller, thereby clamping and conveying the optical cable.
[0023] In order to reduce the force on the screw and ensure the stability of the upper conveying roller, a tension spring 10 is provided between the horizontal plate 36 and the limit block 34 through a fixing rod. The tension spring 10 is located on the front and rear sides of the horizontal plate 36 and the limit block 34.
[0024] In order to facilitate the installation and replacement of the lower conveyor roller, the through groove on the vertical plate passes through to the bottom of the vertical plate, and a fixing block 39 is provided at the lower part of the through groove to cooperate with the limiting groove 33. The bolts pass through the bottom surface of the base plate and are set on the fixing block to fix it. The conveyor roller 9 located at the lower part is set between the two fixing blocks 39.
[0025] At the same time, a waste ink barrel 11 is placed on one side of the middle of the bracket 1 through a support plate. A guide pipe is provided at the bottom of the inverted trapezoidal groove 4, which is connected to the inverted trapezoidal groove and corresponds to the inlet of the waste ink barrel 11. The inverted trapezoidal groove is used to receive ink from the inkjet printer nozzle, and the scattered ink falls through the guide pipe and is collected into the waste ink barrel.
[0026] Furthermore, to ensure the optical cable remains horizontal as it passes from right to left between the two conveyor rollers of the clamping device, below the first guide pulley, and above the second guide pulley, the optical cable must remain horizontal. The first and second L-shaped plates 5 and 7 each have vertically defined oblong through-holes 23. The rear ends of the fixed shafts of the first and second guide pulleys 6 and 8 are secured within these oblong through-holes by two locking nuts. Loosening the locking nuts allows for adjustment of the guide pulleys' fore-aft and up-down positions.
[0027] In addition, in order to make the optical cable plasma processing position as close to the pressing device as possible, the auxiliary device also includes a plasma spray gun fixing bracket to facilitate the arrangement of the plasma spray gun. The plasma spray gun fixing frame includes a vertical arm 12 located at the rear of the bracket, a support arm 13 arranged at the front end of the vertical arm 12, and a fixing assembly. The right side of the support arm 13 is provided with a T-shaped slide groove 14, and a T-shaped block 15 is slidably arranged in the T-shaped slide groove 14; the fixing assembly includes a T-shaped seat 16, a vertical lifting frame 17 and an L-shaped mounting plate 18. The T-shaped seat 16 is arranged on the T-shaped block and can move back and forth along the T-shaped slide groove; the vertical lifting frame 17 is arranged on the right side of the T-shaped seat 16, and an adjustment seat 19 that can move up and down is provided on the vertical lifting frame 17. The adjustment seat 19 is provided with a fixing bolt 20 for fixing the adjustment position. A fixing plate 21 is formed on the lower part of the right side of the adjustment seat 19. The L-shaped mounting plate 18 is arranged on the fixing plate 21, one side of which is provided on the fixing plate, and the other side is used for installing the plasma spray gun. The vertical lift frame 17 is a screw-guide rod lifting mechanism. The adjustment seat sleeve is mounted on the screw guide rod and is threadedly connected to the screw to achieve lifting. The fixing bolt is installed on the adjustment seat and, when tightened, presses against the guide rod to achieve fixation. The T-shaped seat 15 has a mounting groove 22 in the center. The vertical lift frame 17 is equipped with a receiving block that adapts to the mounting groove 22. The receiving block is inserted into the mounting groove and locked with a bolt.
[0028] During use, a fixing clip or other clamping member is placed on the L-shaped mounting plate according to the shape of the plasma spray gun, achieving a vertical arrangement of the plasma spray gun with the nozzle facing downward. The L-shaped mounting plate can be moved back and forth by the T-shaped block, thereby driving the plasma spray gun forward and backward. The vertical lifting frame can also move the L-shaped mounting plate up and down, thereby driving the plasma spray gun up and down, thereby bringing the plasma spray gun nozzle close to and corresponding to the optical cable.
