DEVICE OF DISPLACEMENT OF PRINT HEAD FOR 3D-PRINTER Russian patent published in 2015 - IPC B41F17/00 

FIELD: printing industry.

SUBSTANCE: device of displacement of print head of 3D-printer in the XY plane comprises two longitudinal and at least one transverse guide for displacement of print head in the plane XY, where the longitudinal guides are located on the Y axis and are rigidly fixed to the base, and the transverse guide is located on the X axis between the two longitudinal guides with the ability to move them; a carriage on which the print head is mounted, made with the ability to move along the transverse guide; two drive belts, the ends of which are fixed on the carriage to form two interconnected loops designed to move the carriage with the print head in the XY plane by means of two drive pulleys connected with their drives with the possibility of independent rotation of the pulleys in the same or opposite directions, one of which transmits the tractive force to the first drive belt, and the second - to the second drive belt. One of the loops is formed by P-shaped arrangement of the first belt, and the second loop is formed by the second belt arranged symmetrically relating to location of the first belt with a symmetry axis located parallel to the longitudinal guides and equidistant from them. The working parts of the belts of two loops extending along the transverse guide are located in the same XY plane.

EFFECT: improvement of the device.
