A kind of optical cable ink writer is provided in such as prior art, it mainly comprises frame and lettering case, is provided with type wheel and pinch roller, type wheel is carved characters in lettering case, optical cable is from when being drawn through between pinch roller and type wheel, and the word with ink is imprinted on the surface of optical cable by type wheel.
But without any blocking above the lettering case of existing optical cable ink writer, when optical cable during lettering, if excessive velocities can cause ink to be thrown to optical cable surface, causes quality abnormal, cannot enhance productivity on this optical cable ink writer.
Utility model content
For overcome optical cable ink writer in prior art lettering case above without any blocking, when optical cable is on this optical cable ink writer during lettering, if excessive velocities can cause ink to be thrown to optical cable surface, cause quality abnormal, the problem that cannot enhance productivity, the utility model provides a kind of optical cable ink writer.
The optical cable ink writer that the utility model provides, comprises frame and is arranged on the lettering case of upper end open in frame; Type wheel, pinch roller is provided with in described lettering case; Described lettering case is built with ink;
Described type wheel is carved characters, the reserved gap passed for optical cable between described pinch roller and described type wheel;
Wherein, this lettering case upper end is provided with for drawing optical cable from the guide wheel passed between type wheel and pinch roller, and the upper end open place of described lettering case is also provided with the cover plate preventing ink from flying out, and described cover plate only flows out the cable groove imported and exported for optical cable.
Preferably, described cover plate comprises the left cover and right cover plate that are symmetrically arranged; Described left cover and right cover plate are arranged with symmetrical channels, and described two symmetrical channels unification is described cable groove.
Preferably, described lettering case is also provided with the ink-scraping device striking off excess ink.
Preferably, described frame is provided with motor, the rotating shaft of described motor is connected with the rotating shaft of type wheel.
Preferably, described frame is provided with an electric cabinet, described electric cabinet controls the action of described motor.
Preferably, described left cover and described right cover plate are corrosion resistant plate.
Preferably, arrange ink in described lettering case to draw and get wheel.
The optical cable ink writer that the utility model provides, lettering case has installed cover plate additional, can effectively prevent the too fast phenomenon causing ink to fly to above optical cable of print speed from occurring; While ensureing its optical cable ink writer high-efficiency operation, ensure its lettering effect.

Detailed description of the invention
The technical problem solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with drawings and Examples, are further elaborated to the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment
The optical cable ink writer that this example provides, as shown in Figure 1, comprises frame 2 and is arranged on the lettering case 1 of upper end open in frame 2; As shown in Figure 2, type wheel 12, pinch roller 11 is provided with in described lettering case 1; Described lettering case 1 is built with ink;
Described type wheel 12 is carved characters, the reserved gap passed for optical cable between described pinch roller 11 and described type wheel 12;
Wherein, this lettering case 1 upper end is provided with for drawing optical cable from the guide wheel 3 passed between type wheel 12 and pinch roller 11, the upper end open place of described lettering case 1 is also provided with the cover plate 5 preventing ink from flying out, and described cover plate 5 only flows out the cable groove imported and exported for optical cable.In this example, this cover plate 5 can be the cover plate 5 of integral type, and also can be the cover plate 5 of two pieces of pin-connected panels, described cover plate 5 comprises the left cover 51 and right cover plate 52 that are symmetrically arranged; Described left cover 51 and right cover plate 52 are arranged with symmetrical channels 5a, and described two symmetrical channels 5a unification is described cable groove.In this example, described left cover 51 and described right cover plate 52 are corrosion resistant plate.
Wherein above-mentioned lettering case 1 is stainless steel, Ink cartridge in it, and type wheel 12 rotates in ink, is attached to by ink on type wheel 12, and then realizes the object of ink transfer cylinder on optical cable.Type wheel 12 in this example is suitable for external diameter ¢ 100mm, internal diameter ¢ 20mm, Breadth Maximum 25mm.Lettering quality meets the continuous request such as UL, CSA, VDE, JIS.
Wherein, described lettering case 1 is also provided with the ink-scraping device striking off excess ink, and this ink-scraping device is provided with scraper.By this ink-scraping device, by the ink scraping not at working surface.As preferred mode, can also arrange ink and draw and get wheel (not shown) in lettering case 1, this ink draws to be got wheel and is rotationally connected with type wheel 12, is drawn get wheel by ink smears on type wheel 12 surface by this ink.
Wherein, described frame 2 is provided with motor, the rotating shaft of described motor is connected with the rotating shaft of type wheel 12.In this example, this motor is the motor of single-phase voltage 220V, power 25W, its highest print speed 500m/min,
Wherein, described frame 2 is provided with an electric cabinet 4, described electric cabinet 4 controls the action of described motor.
The optical cable ink writer course of work that this example provides is described below: in the production process of optical cable, utilize the tractive force of optical cable take-up reel, cable is after bosh cooling, the guide wheel 3 mentioned in figure enters in this optical cable ink writer, by pinch roller 11 and type wheel 12 to produce or cable in after-combustion clamps time the moment of friction that produces, force type wheel 12 and pinch roller 11 to rotate, meanwhile, type wheel 12 is immersed in ink.(on type wheel 12, institute's franking is intaglio plate by the ink scraping not at working surface to be forced to the scraper of type wheel 12 on ink-scraping device that rotate, after scraper, also have 0.02 ~ 0.03mm oil residues layer of ink) impress with optical cable close synchronization of undertaking the printing of afterwards, lines and figure clearly can be printed off.In addition, when cable have mould knurl part by this optical cable ink writer time, pinch roller 11 can lift automatically, after moulding knurl and passing through, recovers normal operating conditions voluntarily.
The optical cable ink writer that the utility model provides, lettering case 1 has installed cover plate 5 additional, can effectively prevent the too fast phenomenon causing ink to fly to above optical cable of print speed from occurring; While ensureing its optical cable ink writer high-efficiency operation, ensure its lettering effect.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
