Description
Technical Field
The utility model belongs to the field of 3D printing, and particularly relates to a scraper mechanism capable of rapidly detecting liquid level distance and a 3D printer.
Background
Part of 3D printers work by SLA stereoscopic light curing technology. The basic principle of SLA molding is to irradiate the surface of a liquid photosensitive resin with a laser beam to cure the resin in a specific area of the surface, thereby forming a part of the part. The printing platform is then lowered into the resin to re-cover the cured layer with liquid resin, and the next layer is scanned to firmly attach the new cured layer to the previous cured layer. In order to improve resin re-covering efficiency and shorten molding time, SLA equipment is typically provided with doctor blade modules. When the scraper works, the front edge and the rear edge of the scraper can flatten the excess resin which is higher, so that the liquid level can be flattened as soon as possible, and the negative pressure in the scraper adsorption groove can eliminate bubbles generated by the printing movement of the platform, so that the printing precision is improved. The distance of the doctor blade face from the resin level is therefore particularly important, too little contact, the doctor blade is inoperative, too much contact, and the doctor blade is prone to damage to the finished cured layer. And because no special tool is provided, a debugger can only determine whether the liquid level is proper or not through naked eye observation when adjusting the liquid level, so that the problem of being not intuitive and accurate exists.

The utility model is further described below with reference to the accompanying drawings.
Example 1
Referring to fig. 1-3, a scraper mechanism capable of rapidly detecting a liquid level distance comprises a scraper mounting frame 1 and a scraper body 3 arranged at the lower end of the scraper mounting frame 1, wherein a liquid level probe 5 is arranged on the scraper mechanism, and the liquid level probe 5 detects the distance between the scraper body 3 and a liquid level.
With continued reference to fig. 1 and 2, the left and right sides of scraper body 3 set up spout 30 respectively, the bottom left and right sides of scraper mounting bracket 1 is connected scraper guide 2 through the fastener respectively, scraper guide 2 is T shape structure, the width and the degree of depth of spout 30 and scraper guide 2 assorted, the main part of scraper guide 2 and the slip about corresponding spout 30 are inserted, both sides design has the chamfer around the main part lower extreme, be convenient for insert spout 30, the head 20 of scraper guide 2 is towards 3 one side protrusion of scraper body, this head 20 presss from both sides locates between scraper mounting bracket 1 and the scraper body 3 for form clearance 6 between scraper mounting bracket 1 and the scraper body 3, the thickness of head 20 is great, can play the effect of hiding the fastener, and be fixed through the fastener connection directly between scraper mounting bracket 1 and the scraper body 3.
In another embodiment, the chute 30 may be provided on the blade mount 1 and the blade guide 2 may be fixed to the blade body 3.
With further reference to fig. 1, a liquid level probe 5 is mounted to the doctor mechanism by a probe mount 4.
