Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
As shown in fig. 1 to 5, a manual scraper cleaning device for an SLA3D printer comprises a bracket 1, a cleaning blade mechanism 2 fixedly connected to the bracket 1, and a roller mechanism 3 arranged at one end of the bracket 1 far away from the cleaning blade mechanism 2; the cleaning blade mechanism 2 comprises a base 21, a guide rail 22 arranged on one side, close to the roller mechanism 3, of the surface of the base 21, and a blade 23 arranged on the base 21, wherein the guide rail 22 is matched with a guide groove on an adsorption surface of a3D printer scraper; the roller mechanism 3 comprises a fixed connection between the support 1 and a fixing rod 31 on the same side surface of the base 21, at least one pair of through fixing rods 31 can move towards or away from a movable rod 32 movably arranged in the direction of the base 21, the movable rod 32 is arranged close to a roller device 33 on one side of the base 21, and the movable rod 32 is arranged away from a handle 34 on one side of the base 21.
By arranging the cleaning blade mechanism 2 with variable distance and the roller mechanism 3 and arranging the guide rail 22 matched with the guide groove of the 3D printer scraper on the cleaning blade mechanism 2, the cleaning of the surface of the scraper can be realized without extending hands or disassembling instead by the device provided by the invention. The labor-hour is saved and the cleaning effect is more excellent.
When the scraper of the 3D printer needs to be cleaned, the roller mechanism 3 is firstly contacted with the surface of the scraper, then the handle 34 is pressed downwards, so that the guide rail 22 is matched with the guide groove on the adsorption surface of the scraper, meanwhile, the blade 23 is also contacted with the surface of the scraper, and then the whole device is dragged, and the residual solidified resin on the adsorption surface of the scraper is scraped off by the blade 23.
Because the main working area of the scraper adsorption surface is near the area where the scraper guide groove is located, if the length of the guide rail 22 is too long, two ends of the guide rail 22 are respectively connected with two ends of the base 21, that is, two ends of the guide rail 22 are close to the blade 23, the situation that residual resin at two ends of the scraper guide groove cannot be cleaned easily occurs; if the length of the guide rail 22 is too short, it is difficult to achieve a precise guiding function.
