Description

Scraper cleaner for 3D printer Technical Field The invention belongs to the technical field of auxiliary equipment of 3D printers, and particularly relates to a scraper cleaner for a 3D printer. Background In the 3D printing process, the scraper is used as a key component for scraping materials of the printing platform, such as photosensitive resin and molten plastic, so that the thickness of a formed layer is ensured to be uniform, however, impurities such as solidified materials, dust and the like are easy to remain on the surface of the scraper after long-term working, and if the scraper is not cleaned in time, the scraping precision is reduced, stripes or defects appear on the surface of a printing piece, and even the printing platform is scratched. At present, the scraper cleaning mainly depends on two modes, namely manual cleaning, low efficiency and easy damage to the scraper due to improper operation, and a simple automatic cleaning device is adopted, but the function is single, the simple cleaning can be realized, the real-time detection on the abrasion state of the scraper is lacking, the replacement time cannot be prejudged, the cleaning agent is inconvenient to supply, a liquid storage tank or a spraying device is additionally arranged, the cleaning agent is easy to waste or pollute equipment, and therefore, the scraper cleaner integrating automatic cleaning, abrasion detection and accurate liquid supply is required to improve the 3D printing quality and efficiency. Disclosure of Invention The invention aims to solve the problems and provide the scraper cleaner for the 3D printer, which drives the second screw rod to rotate through the second servo motor to drive the cleaning slide block to slide along the cleaning box, so that the cleaning brush and the infrared seam detector synchronously move to the position of the scraper to be cleaned, when the scraper abuts against the shielding strip, the shielding strip is used as a reference surface for positioning, the cleaning brush rotates to clean residual impurities on the surface of the scraper, and meanwhile, the infrared seam detector detects the gap between the scraper and the shielding strip in real time, thereby realizing the integration of cleaning and detection, avoiding manual intervention and improving maintenance efficiency; When the cleaning slide block moves, the gear in the inner groove is meshed with the rack for transmission, so that the transmission rod and the cleaning brush are driven to rotate, the cleaning agent slowly overflows through a communication structure of the transmission rod and the cleaning brush, the surface of the cleaning brush is uniformly covered, and the decontamination capability is enhanced.
