Abstract
The utility model discloses a thermal printer which mainly comprises a bracket, a worktable arranged on the bracket, a left casing and a right casing which are arranged at two ends of the worktable, wherein a print axle and a drive axle are arranged between the left casing and the right casing, and thermal print heads are arranged on the print axle and connected with the print axle through the thermal print head fixing plate and the aluminum substrate, and the worktable is provided with a support mechanism which mainly comprises supporting bases, a supporting shaft and a supporting plate, and two supporting bases are fixed on the worktable so as to achieve the function of a main basis, and no bearing is arranged on the supporting shaft and the supporting base is provided with a plug, and the supporting shaft and the bearing are connected with the round port and the plug of the supporting shaft through locking screws, and the thermal print heads are staggered to collocate along the aluminum substrate which is bent with a curve of 165-170 DEG C. The technical proposal of the thermal printer ensures that the printing effect is improved and the manufacture process difficulty is reduced.
Description
Technical field:
The utility model relates to a kind of large-scale print apparatus, relates in particular to a kind of thermal printer.
Background technology:
The many employings of scroll machine aluminium base at present popular on the market are flat, and so aluminium base thermal printing head need be lined up in one line, on a datum line.
The shortcoming that exists is: the aluminium base of this pattern is when printing, because it is a lot of that aluminium base is lower than the plane of thermal printing head, so, will cause thermal print media unbalance stress and gauffer takes place in use: simultaneously at the printing initial stage, thermo-sensitive material can be because of the front end transitional function of not delaying time, thermal media can not be firm be attached on the print media, thereby cause printing effect to have apprehensive phenomenon.The incompatibility large-scale industrial production, the maintenance in later stage simultaneously causes very big trouble, has improved the after service cost of product and later stage user's use cost.
The utility model content:
In view of this, the purpose of this utility model provides a kind of thermal printer.
The technical solution of the utility model realizes in the following manner:
A kind of thermal printer, mainly comprise frame, be arranged on the table top on the frame, be arranged on the left casing and the right casing at table top two ends, be provided with print axis and driving shaft between a left side casing and the right casing, print axis is provided with thermal printing head, and thermal printing head is connected to one by thermal printing head fixed head and aluminium base and print axis, table top is provided with support mechanism, support mechanism holds in the palm axle mainly by supporting base, and gripper shoe constitutes, supporting base is two, be fixedly installed on the table top, play the effect of a main body benchmark, the holder axle is provided with bearing, supporting base is provided with plug, circular hole and plug on holder axle and bearing and the supporting base are connected to one by lock screw, and thermal printing head becomes staggered arrangement along aluminium base, wherein, aluminium base is a curved substrate, and curvature is 165-170 °.
The curvature of aluminium base is 170 °.
Being staggered on the aluminium base is provided with thermal printing head, also arranges on the aluminium base and is provided with auxiliary pressure strip.
The cross section of aluminium base is provided with at least two cooling medium holes.
Good effect of the present utility model is:
The technical solution of the utility model is because there is 170 ° frontend curvature in aluminium base, in print procedure, prolonged the splitting time between thermo-sensitive material and the print media, guaranteed that thermo-sensitive material can well be attached on the print media, thereby avoided printing effect apprehensive.
The cooling medium hole owing on aluminium base, distributing, can adopt air-cooled according to actual needs or water-cooled, also can use one or two cooling ducts by master control borad according to the caloric value and the environment temperature decision of thermal printing head as required, guarantee better printing effect.
The utility model also adopts auxiliary pressure strip, can guarantee thermo-sensitive material and the stressed homogeneity of print media when printing, and avoids thermo-sensitive material wrinkling, also avoids thermo-sensitive material to break because of unbalance stress.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an aluminium base structural representation of the present utility model.
Fig. 3 is the structural representation of printhead of the present utility model.
The specific embodiment:
By Fig. 1, Fig. 2 and Fig. 3 as can be seen, this thermal printer, mainly comprise frame 17, be arranged on the table top 16 on the frame 17, be arranged on the left casing 1 and the right casing 2 at table top 16 two ends, be provided with print axis 3 and driving shaft 7 between left side casing 1 and the right casing 2, print axis 3 is provided with thermal printing head 6, thermal printing head 6 connects with print axis 3 by thermal printing head fixed head 4 and aluminium base 5, table top 16 is provided with support mechanism 18, support mechanism 18 is three groups, and one is mounted on the positive medium position of driving shaft 7, two groups of 1/4 places that are symmetrically set in both ends of main drive shaft respectively.Support mechanism 18 is mainly by supporting base 9, holder axle 10, gripper shoe 12 constitutes, supporting base 9 is two, be fixedly installed on the table top 16, play the effect of a main body benchmark, holder axle 10 is provided with bearing 8, supporting base 9 is provided with plug 14, and holder axle 10 and bearing 8 connect by lock screw 15 with plug 14 with circular hole on the supporting base 9, and thermal printing head 6 is staggered up and down along aluminium base 5, wherein, aluminium base 5 and printhead arrangement mode are the thermal printing head 6 that is being staggered on being 170 ° aluminium base 5 in curvature, and are arranging three auxiliary pressure strips 19 on aluminium base too, are becoming on the aluminium base 5 on 170 ° the cross section to be provided with two cooling medium holes 20 simultaneously.
During installation bearing seat, at first two supporting bases 9 are fixed on the table top 16, play the effect of a main body benchmark, and holder axle 10 and bearing 8 connect by lock screw 15 with plug 14 by the slotted hole on the top supporting base 9 then.
Before the use, regulate the length of adjusting screws by the adjustment screw on the rotational support plate 12 11 and promote holder axle 10 and move upward, adjusts the locked lock nut 13 in suitable back, prevent from use to answer adjustment screw 11 to become flexible and cause printing effect bad.
When needs were printed, master control borad sent instruction and is delivered on the control motor of controlling print axis, drove thermal printing head and moved to appointed part, thereby realize printing function.
Aluminium base of the present utility model can be regulated and press down angle according to the difference of print media, thereby reaches the purpose that improves printing effect.
