Embodiment 1

[0031] The feeding assembly includes a material box 211, a guide shaft 217, a pressing rod 218 and an extruding plate 215. The upper part of the guiding shaft 217 is connected to the pressing bar 218, and the lower part of the guiding shaft 217 is connected to the extruding plate 215. The extruding plate 215 cooperates with the inner diameter of the material box 211 , and the bottom of the material box 211 is arranged on a plane.

[0032] Specifically, the material box 211 is used to contain printing materials. The bottom of the material box 211 is parallel to the glass of the material loading platform 22, and the distance is 0.1-0.3 mm. The bottom of the material box 211 requires flatness during processing, which can be Use as a scraper. The material loading platform 22 drives the material to move. After passing through the material box 211, the material is scraped flat by the bottom of the material box and evenly spread on the material loading platform, creating conditions f...

Embodiment 2

[0034] A fixing plate 212 is also included, the fixing plate 212 is located above the material box 211 , and the fixing plate 212 and the material box 211 are positioned through magnetic attraction and / or pin holes.

[0035] Specifically, the fixing plate 212 is used to fix the material box 211. The side of the material box 211 is provided with pin holes, and four circular holes are provided on the top for installing a circular magnetic block. The fixed plate 212 Pin holes are provided on the side, and pins are installed. The material of the fixing plate 212 is iron, and the material box 211 is positioned with the fixing plate by the pins, and is fixed on the fixing plate by the suction force of the magnetic attraction. This facilitates the disassembly and replacement of the material box.

Embodiment 3

[0037] The loading platform 22 includes a loading glass plate 221, a transparent film 225, a glass clamping plate 222, a film clamping plate 223 and a pressing plate 224. The glass clamping plate 222 is provided with a slot, and the loading glass plate 221 is installed In the slot of the glass clamp 222, the transparent film 225 is covered on the film clamp 223, and the surrounding of the transparent film 225 is pressed tightly in the slot of the film clamp 223 by the pressure plate 224, The glass clamp 222 is connected to the film clamp 223 .

[0038] Specifically, the loading platform 22 is used to carry materials, and the loading glass plate 221 is made of a transparent material, which can transmit light from the bottom. The glass clamping plate 222 is empty in the middle and has steps around it. The middle of the clamping plate 223 is empty, and there are grooves all around. The grooves around the film clamping plate 223 match the dimensions of the pressing plate 224, and ...

Abstract

The invention discloses a 3D printing feeding device, a 3D printer and a method, comprising a base, a feeding component, a loading platform and a platform driving component, the feeding component, the loading platform and the platform driving component fixed above the base, the loading platform is located at the lower part of the feeding assembly, the platform driving assembly is located on one side of the loading platform and the feeding assembly, and one end of the platform driving assembly They are respectively connected with the material supply assembly and the material loading platform, and the platform driving assembly drives the material loading platform to supply materials directionally to the working area. The material box is extruded quantitatively, and the platform moves back and forth, which solves the problem of 3D printing of viscous and difficult-to-flow resins, especially applicable to ceramic printing, as well as 3D printing of dental veneers and inlays, which can realize quantitative feeding and save materials , The material box adopts magnetic suction and pin hole positioning, which is convenient for disassembly and replacement. The use of optocoupler, photoelectric block and linear guide rail ensures accurate positioning and improves precision.

Description

technical field [0001] The invention relates to a 3D printer, in particular to a 3D printing quantitative feeding device, a 3D printer and a printing method. Background technique [0002] At present, light-curing 3D printers need to be used to print relatively viscous materials, such as adding a certain proportion of ceramic powder to traditional resin materials. This material is relatively viscous and has poor fluidity, so traditional printing liquid tanks are used for feeding and printing , the material is difficult to self-level, resulting in incomplete printing and poor accuracy, thereby reducing the printing accuracy. Contents of the invention [0003] The technical problem to be solved by the present invention is: the 3D printer needs to be used to print relatively viscous materials, which leads to the problem of poor printing accuracy. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present inventio...
