Cleaning device for sand scraping plate of sand paver

Abstract

The invention relates to the technical field of 3D printers, in particular to a cleaning device for a sand scraping plate of a sand paver of a sand mold 3D printer. The device comprises the sand paverwhich moves horizontally, wherein the sand scraping plate is fixedly arranged at the bottom of the sand paver, and the device further comprises a sweeping wheel, a driving electric motor and a linearmodule which are arranged below the sand paver, wherein the sweeping wheel is located between the sand scraping plate and the linear module, the driving electric motor is in driving connection to thesweeping wheel and is used for driving the sweeping wheel to rotate forwards or reversely, the linear module is parallel to the sand scraping plate, a support is arranged on the linear module in a sliding mode, the sweeping wheel is connected to the linear module in a sliding mode through the support, and a rotating direction of the sweeping wheel is opposite to a sliding direction of the sweeping wheel. The cleaning device for the sand scraping plate of the sand paver is provided and has the beneficial effects that black substances on the sand scraping plate can be effectively removed, and the phenomenon of sand pulling or local blocking of the sand paver is prevented.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a cleaning device for a sand scraping plate of a sand laying device of a sand mold 3D printer. Background technique [0002] The printing sand of the foundry sand mold 3D printer is usually mixed with a variety of additives, which will react with each other and form some black substances that are difficult to clean. Sand mold 3D printers have very high requirements on the smoothness of the sand scraper of the sand spreader during the printing process. During the continuous printing process of the sand mold 3D printer, these black substances will adhere to the sand scraper, which will cause abnormal sand laying of the sand spreader, such as If the black matter attached to the sand scraper is not treated in time, as its volume increases, the black matter attached to the sand scraper may damage the sand surface during the operation of the sand spreader, resulting in The uneven ...

Sand mold 3D printers have very high requirements on the smoothness of the sand scraper of the sand spreader during the printing process. During the continuous printing process of the sand mold 3D printer, these black substances will adhere to the sand scraper, which will cause abnormal sand laying of the sand spreader, such as If the black matter attached to the sand scraper is not treated in time, as its volume increases, the black matter attached to the sand scraper may damage the sand surface during the operation of the sand spreader, resulting in The sand surface is uneven, which affects the quality of the sand mold produced and produces sand mold waste

[0003] After the sand scraper of the sand spreader is used for a long time, there will be pits on the bottom of the sand scraper, where the black matter is easier to collect and crystallize, and a certain volume of black matter will adhere to it and even cause partial blockage of the sand mouth of the sand spreader, which is serious. Affecting the printing production of sand mold 3D printers
