Embodiment 1

[0034] Such as Figure 1 to Figure 2 A thermal printer with multiple print heads shown includes a support composed of an upper support 1 and a lower support 2, and the upper support 1 and the lower support 2 are respectively used for fixedly installing the print head group 3 and the roller group 4 to ensure that when After the cover of the printer casing, the print head group 3 is in contact with the roller group 4 and presses against it.

[0035] The print head group 3 is composed of a print head holder 31 and two or more print lines, each of which is composed of one or more thermal print heads. The thermal print heads are installed on the print head support 31 , and the ends of the effective print areas of every two adjacent thermal print areas are aligned or partially overlapped. By setting alignment or partial overlap, it is ensured that there will be no printing blank area between two spliced ​​printing lines.

[0036] Roller group 4 is made up of roller support 41, two...

Embodiment 2

[0038] A thermal printer with multiple print heads as shown in Embodiment 1, the only difference is that the printing line also includes one or more upper auxiliary rollers, and the upper auxiliary rollers are rotatably arranged on the print head support 31, and in the same printing line, the heating line of the thermal print head is aligned with the center line of the upper auxiliary roller.

Embodiment 3

[0040] A thermal printer with multiple print heads as shown in Embodiment 1, the only difference is that each of the roller units is composed of one or more lower auxiliary rollers, when the printer is closed, the The thermal print head, the upper auxiliary roller and the lower auxiliary roller cooperate.

Abstract

The invention discloses a thermal printer with multiple printing heads. The thermal printer comprises a bracket, a printing head group and a roller group, the printing head group prints patterns on printing paper, the roller group drives the printing paper to move, and the printing head group and the roller group are both installed on the bracket. When the printer is closed, the printing head group and the roller group are in contact for extrusion. The printing head group is composed of a printing head support and two or more printing rows. The roller group is composed of a roller support andtwo or more roller units, the printing head group and the roller group are matched with each other, and by controlling the heating time of each printing row and the rotating direction and distance ofthe roller group, the printing paper of various different specifications is achieved. The thermal printer with the multiple printing heads solves the problems that a thermal printer is fixed in size and cannot meet the requirement for multi-size printing, and has the advantages of being small in size, simple in structure and wide in application range.

Description

technical field [0001] The invention relates to a thermal printer, in particular to a thermal printer with multiple printing heads. Background technique [0002] Thermal printing is widely used in production, warehousing, express logistics, retail and other industries because of its advantages such as simple structure, low failure rate, small size, low price, low cost of consumables, and low energy consumption. [0003] Currently used thermal printers, the printing width of the printer is limited by the width of the thermal print head, the specifications of the commonly used thermal print head are mainly: 2 inches thermal print head (effective printing width is usually 56mm-58mm), There are several limited specifications such as 3-inch thermal print head (effective printing width is usually 76mm-80mm), 4-inch thermal print head (effective printing width is usually 104mm-108mm), and the effective printing size is relatively fixed. Moreover, the cost of thermal printheads wil...
