Abstract
Description
Technical Field
[0001] The utility model relates to the field of printers, in particular to a printing carriage device suitable for super-thick media. Background Art
[0002] The print carriage refers to the part in the printer that is responsible for moving the print head and printing. The carriage refers to the mechanism in the typewriter that is equipped with cast fonts. Because it needs to move left and right during the printing process, it is similar to a vehicle fixed on a track, so it is called a carriage. In modern printers, the carriage mainly refers to the print head of an inkjet printer or a dot matrix printer.
[0003] Most of the existing printers have a carriage with a fixed height, and the printer cannot adaptively adjust the carriage guide shaft according to the thickness of the paper. In addition, the accuracy and stability of the carriage guide shaft when adaptively adjusting according to the thickness of the paper are poor, which makes the use range of the device small. Utility Model Content
[0004] The utility model aims to solve the defect in the prior art that the carriage guide shaft cannot be adaptively adjusted according to the thickness of paper, and proposes a printing carriage device suitable for super-thick media.
[0005] In order to solve the problems existing in the prior art, the utility model adopts the following technical solutions:
[0006] A printing carriage device adapted to super-thick media comprises a pair of fixed blocks, one side of the pair of fixed blocks is provided with a lower pressure roller, a transfer roller is provided below the lower pressure roller, a connecting assembly is provided on the side of the transfer roller, and an adjustment mechanism is provided on the pair of fixed blocks.
[0007] Preferably, the connecting assembly includes a pair of connecting rods, each of which is rotatably connected to a fixed block, each of which is rotatably connected to a lower pressure roller, and a pair of fixed rods are rotatably provided at the end of the transfer roller, each of which is fixedly connected to a fixed block, and each of which is rotatably connected to the connecting rod.
[0008] Preferably, a detector is fixedly provided on one of the connecting rods.
[0009] Preferably, the adjustment mechanism includes a pair of slide grooves, the slide grooves are both opened on one side of the fixed block, slide rails are fixedly provided in the slide grooves, sliders are slidably provided in the slide grooves, a sliding groove is opened on one side of the slider, the sliding grooves are slidably connected to the slide rails, and a motor is fixed on the fixed block.
[0010] Preferably, a carriage guide rail is fixedly provided between the pair of sliders, and a carriage guide shaft is fixedly provided between the pair of sliders.
[0011] Preferably, a print head is slidably provided on the carriage guide shaft, and the print head is slidably connected to the carriage guide rail.
[0012] Preferably, two pairs of mounting blocks are fixedly provided on the fixing blocks.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] In the utility model, when the paper reaches one side of the transfer roller, the transfer roller transfers the paper to the side of the adjustment mechanism. At this time, the lower pressure roller presses the paper tightly, and the detector detects the angle between the transfer roller and the pressure roller to judge the thickness of the paper. The adjustment mechanism then adjusts the height of the print head to facilitate printing on different papers and can print on ultra-thick media. BRIEF DESCRIPTION OF THE DRAWINGS
