Embodiment
In order to allow above-mentioned feature and advantage of the present utility model become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
As shown in Figure 1, a kind of proving installation of thermal printer paper delivery driving force, comprise the platform 1 being close to thermal printer, the surface of described platform 1 is mutually concordant with the paper feed direction of thermal printer 10, the paper delivery direction of described thermal printer 10 deviates from platform 1, described platform 1 erects and is provided with support 2, described support 2 is provided with crossbeam 3, described crossbeam 3 is provided with the spring balance 4 of varying height positions, described platform 1 is also provided with lever 5, one end of described lever 5 is connected with the lower end of spring balance 4, the other end of described lever 5 is connected with the briquetting 6 for press against print paper 11.
In the utility model embodiment, described crossbeam 3 fixes non-adjustable connection with support 2, such as fixing welding; The shell upper end of described spring balance 4 is fixed with an adjustment montant 7, described adjustment montant 7 is connected with crossbeam about 3 is adjustable, such as can adopt bolt and nut adjustment or rack-and-pinion adjustment etc., as long as the height and position regulating montant 7 can be changed, and then the height and position of regulating spring scale 4.Certainly, described crossbeam 3 also can be connected with support about 2 is adjustable, by the height and position regulating the height and position of crossbeam 3 to carry out regulating spring scale 4.
In the utility model embodiment, described adjustment montant 7 is screw rod, and the upper end of described screw rod is fixed by nut 8 through after the through hole on crossbeam 3, by rotating nut 8, screw rod is moved up and down during test, and then the height and position of regulating spring scale 4; Certainly, described adjustment montant 7 also can be polished rod, and the upper end of described polished rod is fixed by screw through after the through hole on crossbeam 3, first can unclamp screw, then improve polished rod, last lock screw during test.
In the utility model embodiment, the lower spring end of described spring balance 4 is fixed with a force rod 9, and the lower end of described force rod 9 and one end of lever 5 are linked.Certainly, the lower spring end of described spring balance 4 also can arrange a hook, is caught on one end of lever 5, as long as the lower spring end of spring balance 4 can be flexibly connected with one end of lever 5 by hook.
In the utility model embodiment, the fulcrum of described lever 5 is positioned at its center; Certainly, the fulcrum of described lever 5 also can be close to any one end, does not affect the positive correlation of the full-scale reading of spring balance 4 and the maximum gauge of printing paper roll.Described briquetting 6 top can be hinged with the other end of lever 5, keeps in touch to make briquetting 6 and print paper 11.
As shown in Figure 1 and 2, a kind of method of testing of thermal printer paper delivery driving force, adopts above-mentioned proving installation, and carries out according to the following steps:
