Problems solved by technology

However, the current double-knife scraper device can't handle the viscous ceramic slurry well, that is, it can't do automatic feeding, and both feeding and tool changing require the assistance of staff, so printing often occurs due to human factors. When the accuracy does not meet the requirements
In addition, the current double-knife structure scraper device has a complicated structure, which makes the blade change method slow, unstable and unreliable

Abstract

The invention provides an electromagnetic bidirectional switching scraper device applied to a 3D printer. The electromagnetic bidirectional switching scraper device comprises a horizontal moving sliding plate, a scraper frame and a height limiting base; scrapers and limiting guide rods are arranged on the two sides of the scraper frame; and the scraper frame is connected with the horizontal movingsliding plate through a rotating shaft, when the scraper frame reaches the position of the height limiting base, the limiting guide rods make contact with an inclined wedge face on the top of the height limiting base and move downwards, the scraper frame swings on the horizontal moving sliding plate, and therefore the scrapers on the two sides of the scraper frame are switched. Automatic switching of the double scrapers is achieved during left-right movement, the automatic feeding problem of the 3D printer is solved, an electromagnet device and the height limiting base are used in cooperation, the scraper precision is guaranteed, meanwhile, the scraper replacing process is faster, the scraper replacing manner is stable and reliable, and the 3D printer can achieve unmanned and automatic operation, machining and feeding through the scraper device, so that the problem that the manual smearing precision is not stable is solved, and the problems about working precision, efficiency and reliability are solved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to an electromagnetic bidirectional switching scraper device applied to a 3D printer. Background technique [0002] Fully automatic SLA laser 3D printers often use a scraper device. The principle is to divide the printed object into several layers, and add a layer of raw materials for each layer of solidification. The scraper device is to evenly smear the raw material on the workbench. The scraper device generally adopts a single-blade type, and the single-blade efficiency is not high and cannot achieve the desired effect. Therefore, those skilled in the art propose a scraper device with a double-knife structure. However, the current double-knife scraper device can't handle the viscous ceramic slurry well, that is, it can't do automatic feeding, and both feeding and tool changing require the assistance of staff, so printing often occurs due to human factors. Accura...
