Problems solved by technology
[0010] The present invention aims at problems such as uneven product density, powder waste and pollution caused by uneven powder falling amount in the powder spreading process of the existing powder spreading device, as well as relatively large noise caused by powder falling caused by vibration; it provides a A conveyor belt-type unloading device, which can be used to spread powder layer by layer in additive manufacturing. This device can realize uniform falling of powder, precise control of falling amount, and precise control of falling start and end time, thereby improving the quality of additive manufacturing products. High yield, reduce boring loss and improve product surface quality and precision

Embodiment Construction
[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0030] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right", "top", "bottom", "bottom", "top" and similar expressions...

The invention relates to a conveyor belt type discharging device. The conveyor belt type discharging device comprises a feeding mechanism, a material storage mechanism, a flat scraping mechanism and main beams, wherein the feeding mechanism is arranged above the material storage mechanism; the main beams are arranged at two sides of the material storage mechanism; the flat scraping mechanism is arranged under the material storage mechanism; the feeding mechanism conveys powder into the material storage mechanism; the material storage mechanism conveys the powder to the flat scraping mechanism;and the flat scraping mechanism flatly scraps the powder conveyed from the material storage mechanism. The conveyor belt type discharging device provided by the invention aims at the problems that inthe powder laying process of an existing powder laying device, the powder falling amount is not uniform, so that the product density is not uniform, the powder is wasted, pollution is caused, and thelike. The conveyor belt type discharging device provided by the invention can be used for laying the powder layer by layer in additive manufacturing, and can realize uniform falling of the powder, accurate control of the falling amount and accurate control of the falling starting and stopping time, so that the yield of additive manufacturing products is improved, the loss is reduced, and the surface quality and precision of the products are improved.
Description
technical field [0001] The invention relates to the field of additive manufacturing, in particular to a conveyor belt type unloading device. Background technique [0002] Additive manufacturing and subtractive manufacturing correspond to each other. They are the two mainstream manufacturing technologies at present. There are many known additive manufacturing processes. Among them, some additive manufacturing processes using powder molding have the following general steps: [0003] (1) First, applying the powdery material to the entire surface of the manufacturing platform so as to form a layer of unformed powdery material; [0004] (2) Secondly, through selective inkjet, sintering and other methods of treatment, the powder laid on the manufacturing platform is selectively formed in a predetermined part of the area, and the unformed powder is kept in a loose state; [0005] (3) Steps (1) and (2) are repeated, and stacked layer by layer to manufacture components. For this pu...
