Embodiment Construction

[0026] The best way to implement the invention

[0027] Reference figure 1 The printing device 2 of the cigarette making machine has a printing roller row 4, and the printing roller row 4 is rotatably installed on the main frame (not shown in the figure) of the cigarette making machine. The printing device 2 is covered by a cover 6, and the cover 6 is hinged to the main frame. figure 1 In the figure, the cover 6 is shown by a one-dot chain line.

[0028] At the beginning of the printing roller row 4 there is a pair of input rollers (ink rollers) 8, 10, and the ink rollers 8, 10 are connected to each other in rotation. The input roller 8 on one side is made of metal, and the input roller 10 on the other side is made of rubber. The input roller 10 is rotatably connected with a printing roller (rolling plate) 16 through an extension roller 12 made of metal and a transfer roller 14 made of rubber. The printing roller 16 is arranged at the end of the printing roller row 4.

Abstract

A printing device for printing on wrapping paper according to the present invention comprises a cartridge holder (40) having an ink nozzle (18) on the outside thereof and adapted to house an ink cartridge (50); an ink supply passage (79) connecting the ink cartridge (50) and the ink nozzle (18); and a linear actuator (80) supported at the cartridge holder (40) and adapted to push a plunger (52) in the ink cartridge (50) more into the ink cartridge (50).

Description

Technical field [0001] The present invention relates to a printing device for printing prescribed information on the rolled paper during the process of continuously packaging shredded tobacco to make cigarettes. Background technique [0002] Such a printing device is disclosed in, for example, Japanese Patent Application Laid-Open No. 56-164867. This known device has an ink reservoir for storing ink, an ink jet port communicating with the ink reservoir via a supply path, and a gear pump inserted in the supply path. Once the gear pump is driven, the gear pump supplies the ink in the ink reservoir to the ink jet port through the supply passage. [0003] In the above-mentioned printing device, in order to maintain the clarity of the information printed on the roll paper, that is, the printing density, it is necessary to control the amount of ink supplied to the inkjet ports according to the printing density. Although the amount of ink supply can be adjusted by controlling the drivin...
