Abstract
The utility model discloses a printing roller composition of a needle printer; the printing roller composition comprises a machine rack provided with a rod-shaped solid metal printing roller; two sides of the machine rack are respectively provided with a card slot; two ends of the solid metal printing roller are respectively clamped in the card slot; because the solid metal printing roller of the printing roller composition of the printer is big in mass weight, vibrations of the printing roller is well reduced in hitting and bumping of printing needles, thereby reducing noises generated from noise resource; the printing roller composition has better durability than that of a plastic printing roller, thereby prolonging usage life of the printer.
Description
Technical field
The utility model relates to the marking roll structure of a kind of impact printer, particularly a kind of impact printer.
Background technology
The operation principle of impact printer is: rely on the print needle of needle type print head to clash on print platform, make the colour band between printhead and platform on paper, leave print What.Hence one can see that, and this kind impacts the printer of image-forming principle in the course of the work easily because the shock of print needle and print platform produces noise, and therefore, pursuing the more impact printer of low noise is research direction of the present utility model.
In traditional impact printer, print platform is that the base material of marking roll is selected normally two kinds: plastic cement or sheet metal; Hit noise while adopting plastic cement can contribute to reduce printing as marking roll base material, but the durability of plastic cement marking roll is poor, and easily loss, is difficult to long-term use; Although and employing sheet metal has possessed good durability as marking roll base material, the hit noise while printing is larger, affects surrounding environment.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of marking roll structure of impact printer, and existing good durability can effectively reduce operating noise again.
In order to solve the problems of the technologies described above, the marking roll structure of a kind of impact printer of the present utility model, comprises frame, and bar-shaped solid metal marking roll is installed in described frame, frame both sides are respectively arranged with draw-in groove, and these solid metal marking roll two ends are installed on respectively in described draw-in groove.
On described solid metal marking roll, but the back side relative with its strike working face is provided with the sheet that shakes, but the described sheet that shakes is fixed by elastic cord breaker and described solid metal marking roll.
Described elastic cord breaker is mucigel.
But described shake chip size and the described solid metal marking roll back side basically identical, density and described solid metal marking roll are basically identical.
Described solid metal marking roll two ends are respectively installed with shock-absorbing sleeve, and are installed in described draw-in groove by shock-absorbing sleeve.
Described shock-absorbing sleeve is pasted with ground strip outward.
On described draw-in groove, be provided with described shock-absorbing sleeve is fixed on to the tightening buckle in draw-in groove.
The beneficial effects of the utility model are: the marking roll structure of impact printer of the present utility model, adopt bar-shaped solid metal marking roll to be installed in the draw-in groove of frame, because the quality of solid metal marking roll is larger, print needle impact collision in can the fine vibration that weakens marking roll, thereby reduce the noise that noise source produces, and there is better durability than plastic cement marking roll, be conducive to extend the useful life of impact printer.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposition texture schematic diagram of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, the marking roll structure of a kind of impact printer of the present utility model, comprises frame 1, and bar-shaped solid metal marking roll 2 is installed in described frame 1, frame 1 both sides are respectively arranged with draw-in groove 3, and these solid metal marking roll 2 two ends are installed on respectively in described draw-in groove 3.Marking roll structure at this printer, because the quality of solid metal marking roll is larger, print needle impact collision in the deformation that produces less, can weaken well the vibration of marking roll, thereby reduce the noise that noise source produces, and there is better durability than plastic cement marking roll, be conducive to extend the useful life of printer.
As preferred embodiment of the present utility model, on described solid metal marking roll 2, but the back side relative with its strike working face is provided with the sheet 4 that shakes, but the described sheet 4 that shakes is fixed by elastic cord breaker 8 and described solid metal marking roll, preferably, elastic cord breaker can adopt mucigel, but will shake sheet 4 be adhesively fixed with solid metal marking roll 2.When in the course of work, print needle impacts marking roll, because but the marking roll back side is fixed with by elastic cord breaker 8 sheet 4 that shakes, the Impact energy that makes print needle impact marking roll is absorbed buffering afterwards again to air borne, thereby has reduced amplitude, weakened vibration, finally reached and reduce noise object.
For the vibrational energy of each position of marking roll all can be absorbed, but the size of the described sheet 4 that shakes and the marking roll back side are basically identical, and the effect of vibration damping can be better like this.In addition, but the density of the sheet that shakes is higher, and also better to the assimilation effect of vibrational energy, the secondary vibration of generation is also fewer, and therefore, but the sheet that shakes can adopt the metal material basically identical with described solid metal marking roll density.
In the present embodiment, solid metal marking roll 2 two ends are respectively installed with shock-absorbing sleeve 5, and be installed in described draw-in groove 3 by shock-absorbing sleeve 5, shock-absorbing sleeve can absorb the vibration of marking roll, and make marking roll 2 except contacting with print needle, no longer there is other the generation that contacts with frame, cut off the transmission of vibration, thereby thereby avoid vibration in too much transmission, to produce secondary noise source.
On draw-in groove 3, be also provided with shock-absorbing sleeve 5 is fixed on to the tightening buckle 7 in draw-in groove, make the structure of product more firm, and the easy accessibility of tightening buckle, be conducive to installation and maintenance.
In addition, while rubbing on marking roll due to paper, easily produce static, therefore outside shock-absorbing sleeve 5, be pasted with ground strip 6, the static producing can be taken out of in time on shock-absorbing sleeve, prevent that work impacts to printer for it.
The utility model engages Machine Design with the propagation principle of acoustics, by prior art being carried out the least possible, improve dexterously, makes the noise reduction of printer obtain excellent lifting, can be widely used on the various printers that impact image-forming principle.
The above embodiment is only preferential embodiment of the present utility model; not the restriction to the utility model protection domain, as long as within the embodiment that realizes the utility model technique effect with essentially identical technological means should belong to protection domain of the present utility model.
