Abstract
The invention discloses a kind of marking roll structure of impact printer, comprise frame, bar-shaped solid metal marking roll is installed in frame, frame both sides are respectively arranged with draw-in groove, these solid metal marking roll two ends are installed on respectively in described draw-in groove, in the marking roll structure of this printer, 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 printer.
Description
Technical field
The present invention relates to the marking roll knot of a kind of impact printer, particularly a kind of impact printerStructure.
Background technology
The operation principle of impact printer is: rely on the print needle of needle type print head at print platformUpper shock, makes the colour band between printhead and platform on paper, leave print What. ThusKnown, this kind impacts the printer of image-forming principle in the course of the work easily because print needle and printing are flatThe shock of platform and produce noise, therefore, it is of the present invention pursuing the more impact printer of low noiseResearch direction.
In traditional impact printer, print platform is that the base material of marking roll selects normally twoKind: plastic cement or sheet metal; Adopting plastic cement can contribute to reduce as marking roll base material beatsHit noise when seal, but the durability of plastic cement marking roll is poor, and easily loss, is difficult to longPhase is used; And although employing sheet metal has possessed good durability as marking roll base material,But the hit noise while printing is larger, affects surrounding environment.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of marking roll structure of impact printer,Existing good durability, can effectively reduce again operating noise.
In order to solve the problems of the technologies described above, the marking roll structure of a kind of impact printer of the present invention,Comprise frame, bar-shaped solid metal marking roll is installed in described frame, frame both sides respectivelyBe provided with draw-in groove, 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 and shakesSheet, 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 instituteState solid metal marking roll basically identical.
Described solid metal marking roll two ends are respectively installed with shock-absorbing sleeve, and clamp by shock-absorbing sleeveIn described draw-in groove.
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 invention has the beneficial effects as follows: the marking roll structure of impact printer of the present invention, adoptsBar-shaped solid metal marking roll is installed in the draw-in groove of frame, due to solid metal marking rollQuality is larger, print needle impact collision in can the fine vibration that weakens marking roll, thereby fallThe noise that low noise source of sound produces, and there is better durability than plastic cement marking roll, be conducive toExtend the useful life of impact printer.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Fig. 2 is decomposition texture schematic diagram of the present invention.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, the marking roll structure of a kind of impact printer of the present invention, comprises machineFrame 1, is provided with bar-shaped solid metal marking roll 2 in described frame 1, frame 1 both sides respectivelyBe provided with draw-in groove 3, these solid metal marking roll 2 two ends are installed on respectively in described draw-in groove 3.In the marking roll structure of this printer, because the quality of solid metal marking roll is larger, beatingPrint pin to impact the deformation producing in collision less, can weaken well the vibration of marking roll, fromAnd reduce the noise that noise source produces, and there is better durability than plastic cement marking roll, haveBe beneficial to the useful life that extends printer.
As the preferred embodiment of the present invention, on described solid metal marking roll 2, with its dozenBut hit the back side that working face is relative and be provided with the sheet 4 that shakes, but the described sheet 4 that shakes is by elastic cord breaker 8Fix with described solid metal marking roll, preferably, elastic cord breaker can adopt mucigel, willBut the sheet 4 that shakes is adhesively fixed with solid metal marking roll 2. When impacting, beats print needle in the course of workWhile printing roller, but because the marking roll back side is fixed with by elastic cord breaker 8 sheet 4 that shakes, make to beatThe Impact energy that seal pin impacts marking roll is absorbed buffering afterwards again to air borne, thereby reducesAmplitude, weakened vibration, finally reach and reduce noise object.
For the vibrational energy that makes each position of marking roll all can be absorbed, but the described sheet 4 that shakesSize and the marking roll back side are basically identical, and the effect of vibration damping can be better like this. In addition, but shake sheetDensity higher, also better to the assimilation effect of vibrational energy, the secondary vibration of generation is also fewer,Therefore, but the sheet that shakes can adopt the metal material basically identical with described solid metal marking roll densityMatter.
In the present embodiment, solid metal marking roll 2 two ends are respectively installed with shock-absorbing sleeve 5, and logicalCross shock-absorbing sleeve 5 and be installed in described draw-in groove 3, shock-absorbing sleeve can absorb the vibration of marking roll, andMake marking roll 2 except contacting with print needle, no longer have other the generation that contacts with frame, everyThe transmission of vibration of having broken, thus 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 productStructure more firm, and the easy accessibility of tightening buckle, is conducive to installation and maintenance.
In addition, while friction on marking roll due to paper, easily produce static, therefore at shock-absorbing sleeveOutside 5, be pasted with ground strip 6, the static producing can be taken out of in time on shock-absorbing sleeve, prevent that it is rightPrinter work impacts.
The present invention engages Machine Design with the propagation principle of acoustics, by prior art is enteredGo the least possible and improve dexterously, making 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 invention, is not that the present invention is protectedThe restriction of scope, as long as realize the reality of the technology of the present invention effect with essentially identical technological meansExecute within example all should belong to protection scope of the present invention.
