Embodiment Construction

[0044] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings as necessary. In addition, in the drawings, the same reference numerals are assigned to the same elements, and overlapping descriptions are omitted. In addition, unless otherwise specified, positional relationships such as up, down, left, and right are based on the positional relationships shown in the drawings. Also, the dimensional ratios of the drawings are not limited to the illustrated ones.

[0045] figure 1 It is a schematic side view showing an embodiment of the inkjet printing device of the present invention.

[0046] Such as figure 1 As shown, the inkjet printing device 100 of this embodiment has: a printing unit 5, which applies ink to the object to be printed 1; a drying drum 3, which is used to heat and dry the printed object 1a to which the ink is applied; a control device 4 , which can respectively control the heating of a plurality o...

Abstract

The present invention provides an inkjet printing apparatus capable of greatly suppressing temperature imbalance of the drying drum itself. The present invention is an inkjet printing device (100), which is characterized in that it has: a printing part (5), which applies ink to a printed object (1); a drying drum (3), which is used to apply the ink The printed body (1a) is in contact with the outer peripheral surface of the drying drum to heat and dry the printed body; the control device (4) can respectively control the heating of a plurality of division parts (31a), and the plurality of division parts (31a) The drying drum (3) is formed by dividing the drying drum (3) by a surface perpendicular to the axis direction, and a heating part (13) capable of heating the division part (31a) is respectively installed in each division part (31a). The heating of the heating portion (13) of all the divided portions (31a) is continuously controlled.

Description

technical field [0001] The present invention relates to an inkjet printing device, and more specifically, to an inkjet printing device including a control device for making the temperature of a drying drum reach a target temperature. Background technique [0002] In the field of printing, a printed body that is printed on an object to be printed by an inkjet method is heated and dried by a heating device. [0003] At this time, in order to heat and dry the printed body efficiently, various heating controls are performed on the heating device. [0004] As the above-mentioned heating control, for example, PID control which is one of feedback control is known. In PID control, the input value is controlled by three elements: the deviation between the output value and the target value, its integral, and its derivative. [0005] In addition, as a specific example, there is known a recording device (for example, refer to Patent Document 1) that performs heater temperature control...
