The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of plane marking roll of impact printer, and it has and uses that raw material are few, quality is light, noise reduction effect good, print quality is high, the Applicable temperature scope is wide, can be applicable to the characteristics such as extreme temperature conditions.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of plane marking roll of impact printer, it comprises support, and support is connected with along the two ends of its length direction support is fixed on back shaft on printer support, and supporting the tip of the axis is special-shaped installed surface; Described top of the trellis is provided with draw-in groove section, is injected with the flexible glue layer in draw-in groove section, and the median surface of flexible glue layer is horizontal plane, and two sides are the inclined plane.
As improvement of the technical scheme, described support is provided with axis hole along the two ends of its length direction, back shaft be circular shaft and interference fit in the axis hole of support, the hole of axis hole is along being provided with air discharge duct.
As further improvement in the technical proposal, be filled with the sound-absorbing filler in the axis hole of described support.
Further, described back shaft is circular shaft and is welded in support along the two ends of its length direction.
Preferably, the thickness of the median surface of described flexible glue layer is below 2.0mm.
Further, described special-shaped installed surface is a D shape face.
The beneficial effects of the utility model are: the utility model makes and the location is installed conveniently, accurately between marking roll and frame by being provided with special-shaped installed surface at the support the tip of the axis; Be provided with draw-in groove section by top of the trellis, be injected with the flexible glue layer in draw-in groove section, the median surface of flexible glue layer is horizontal plane, two sides are the inclined plane, make the flexible glue layer can not get loose from support, median surface is horizontal plane, makes the print job face identical with distance between printhead, guaranteed that the ink marks that printhead prints on paper is even, improved print quality; In addition, this structure can be guaranteed the thinner thickness of flexible glue layer, be bonded on whole center circular shaft and the thicker rubber layer of thickness with respect to gluing in conventional art, guaranteed that printer spacing between print job face and printhead in the temperature range of regulation only has few variation, can effectively improve the print quality under extreme temperature conditions.The utility model is simple and reasonable, the use raw material are few, quality is light, noise reduction effect good, print quality is high, can be applicable to extreme temperature conditions.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another angle structural representation of the utility model (hiding the flexible glue layer);
Fig. 3 is that the utility model medium-height trestle is along the front view of its length direction.
The specific embodiment
with reference to Fig. 1 ~ Fig. 3, the plane marking roll of a kind of impact printer of the present utility model, it comprises support 1, support 1 is connected with along the two ends of its length direction support 1 is fixed on back shaft 3 on printer support, support 1 and back shaft 3 adopt stainless steel or aluminum alloy materials, preferably be provided with axis hole 11 at described support 1 along the two ends of its length direction, back shaft 3 is that circular shaft and interference fit are in the axis hole 11 of support 1, the hole of axis hole 11 is along being provided with air discharge duct 12, bracing frame 3 is arranged to circular shaft and is convenient to processing, clamping, check, assembling and positioning and precision are higher, with back shaft 3 interference fit in the axis hole 11 of support 1, guarantee that back shaft 3 and support 1 relative motion can not occur in the course of the work, the hole of axis hole 11 is the air of discharging when being pressed into axis hole 11 for back shaft 3 in axis hole 11 along the air discharge duct 12 of locating to arrange, alleviate air drag, be convenient to install.
Certainly, also described back shaft 3 can be set to circular shaft and be welded in support 1 along the two ends of its length direction.
The end of described back shaft 3 is provided with special-shaped installed surface 31, is provided with corresponding irregularly-shaped hole on printer support to coordinate special-shaped installed surface 31, and preferred described special-shaped installed surface 31 is a D shape face, guarantees the print job face level of flexible glue layer 4.Certainly, special-shaped installed surface 31 also can be hexagonal surfaces etc.
