Abstract
The utility model discloses a board for assembly of a broad-width heat-sensitive printing head, which comprises a bottom surface, a base surface, a left end face, a right end face, an upper end face and a lower end face. The base surface is used for fixing a heat-sensitive printing head, a bolt through hole is arranged between the bottom surface and the base surface, and the upper end part of the base surface is provided with a boss used for positioning the heat-sensitive printing head. Due to the boss used for positioning the heat-sensitive printing head, multiple heat-sensitive printing heads can be butted rapidly and accurately during assembly, thereby reducing the technical difficulty in assembly and improving the assembly efficiency. Moreover, the utility model can facilitate the reassembly during later maintenance and replacement of heat-sensitive printing heads. The boss is contacted with the heat-sensitive printing head in a positioning way, thereby increasing the heat dissipation area and improving the heat dissipation. In addition, since only one boss is additionally arranged, the utility model has the advantages of simple structure and low cost.
Description
Technical field
The utility model relates to the wide cut thermal printer, in particular for the machine plate of assembly unit wide cut thermal printing head.
Background technology
The thermal printing head of wide cut thermal printer is at present to be made of on the machine plate the narrower thermal printing head splicing of a plurality of breadths mostly.Described machine plate mainly contains two effects, and the one, fixing thermal printing head, the 2nd, be the thermal printing head heat radiation.This machine plate is generally the cuboid of being made by aluminium, and it comprises the bottom surface, is used for fixing the basal plane of thermal printing head, left and right end face, upper and lower end face; Offer through hole between described bottom surface and basal plane, bolt passes this through hole from the bottom surface, is spirally connected with screw on the thermal printing head that is placed on the basal plane.The machine plate of this structure has only basal plane to contact with thermal printing head, causes to have following problem: 1, when the assembly unit thermal printing head, thermal printing head can't be located, and must splice with special-purpose instrument check and correction, and the splicing difficulty is big, efficient is low, later maintenance inconvenience; 2, because have only basal plane to contact with thermal printing head, contact area is little, and heat dispersion is bad.
The utility model content
The purpose of this utility model is: a kind of machine plate that is used for assembly unit wide cut thermal printing head is provided, not only can be efficiently, the accurate in locating thermal printing head, and the radiating efficiency height, simple in structure.
For achieving the above object, the utility model can be taked following technical proposals:
The utility model is used for the machine plate of assembly unit wide cut thermal printing head, it comprises the bottom surface, the basal plane that is used for fixing thermal printing head, left and right end face, upper and lower end face, between described bottom surface and basal plane, offer screwing through hole, be provided with the boss that is used to locate described thermal printing head in the upper end of described basal plane.
Described boss and machine plate are structure as a whole, and its left and right two ends extend to described left and right end face respectively, and its upper end extends to described upper surface, and its lower surface is the locating surface vertical with described basal plane.
Upper end between described left and right end face is provided with the heat radiation straight channel that is used to feed liquid state or gaseous state coolant; The boss upper surface of described boss is parallel to described basal plane, the distance from this boss upper surface to basal plane less than the upper surface of thermal printing head to basal plane apart from the 0.05-0.1 millimeter; The intersection of this boss upper surface and upper surface is an arc structure; Described screwing through hole is five, divides the two rows setting, and last row is provided with three screwing through hole, and following row is provided with two screwing through hole, and arranges the screwing through hole along continuous straight runs up and down and equidistantly be misplaced.
The technical solution of the utility model, owing to be provided with the boss that is used to locate described thermal printing head, make when the assembly unit thermal printing head, can be fast, accurately a plurality of thermal printing heads are docking together, reduced the technical difficulty of splicing, improved the efficient of splicing, and in the maintenance in later stage, when changing thermal printing head, to being brought great convenience from new assembly unit.Boss contacts with the thermal printing head location, has strengthened area of dissipation, has improved heat dispersion.And the utility model only is to have increased a boss, and simple in structure, cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to the structure for amplifying schematic diagram.
The specific embodiment
As depicted in figs. 1 and 2, the utility model is used for the machine plate of assembly unit wide cut thermal printing head, and it comprises bottom surface 1, is used for fixing the basal plane 3 of thermal printing head 2, left and right sides end face 4,5, upper and lower end face 6,7; Between described bottom surface 1 and basal plane 3, offer five sunk screw through holes 8 that the branch two rows are provided with, last row is provided with three, following row is provided with two, and arranging sunk screw through hole 8 along continuous straight runs up and down equidistantly is misplaced, can improve the fixedly bed knife of thermal printing head like this, reduce by a screwing through hole than prior art, the hole diameter of described sunk screw through hole 8 is greater than 1 millimeter of the diameter of thermal printing head screw, and this is convenient to adjust thermal printing head position in the horizontal direction; Be provided with the boss 9 that is used to locate thermal printing head 2 in the upper end of described basal plane 3, described boss 9 is structure as a whole with the machine plate, its two ends, left and right sides extend to described left and right sides end face 4,5 respectively, and its upper end extends to described upper surface 6, and its lower surface is the locating surface 10 vertical with described basal plane 3; Upper end between described left and right sides end face 4,5 is provided with the heat radiation straight channel 12 that is used to feed liquid state or gaseous state coolant, and the resistance of 12 pairs of feedings of through-type heat radiation straight channel coolant wherein reduces, and radiating effect is better; The boss upper surface 11 of described boss 9 is parallel to described basal plane 3, the distance from this boss upper surface 11 to basal plane 3 less than the upper surface of thermal printing head 2 to basal plane 3 apart from the 0.05-0.1 millimeter, help thermal printing head work; This boss upper surface 11 is an arc structure with the intersection of upper surface 6, is convenient to colour band and passes through, and improves the service life of colour band.
