WIPO Patent Application WO/2021/134530
Kind Code:
A1
Abstract:
A drawing printer with a wide range of variable print sizes, comprising a chassis, wheels, shafts, an electric motor, a print head, a print sliding rail, and a print support. Each of the shafts can telescope and is used for connecting to the wheels, and the wheels and the shafts are mounted under the chassis and are driven by the electric motor to travel on the ground. The print sliding rail can telescope and is mounted on the chassis by means of the print support. The print head can print a pixel dot matrix on the ground, print row pixels by means of reciprocating on the print sliding rail, and switches to another row by means of the travelling of the chassis with respect of the ground. The print head can print one or more rows of pixels each time moving unidirectionally from one end to the other end of the print sliding rail. The print head is moved on an adjustable-size axle, thus having a wide range of variable print sizes.
