Embodiment Construction

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0028] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0029] In addition, the terms "first" and "second" are only used for descriptive purposes, and should not be construed as indicating or implying relative importance or implying the number of indicated tech...

Abstract

The invention provides a powder feeding device for powder ink-jet bonding printing. The powder feeding device comprises a negative pressure generator, a weighing tank, a powder falling control mechanism, a powder mixing tank and a powder discharging control mechanism. A discharge port of the negative pressure generator is communicated with the weighing tank, and a powder suction port is formed in the negative pressure generator; negative pressure is generated in the negative pressure generator, so that the powder suction port can suck powder and the powder enters the weighing tank; a weighing sensor is arranged on the weighing tank, so that the weight of powder in the weighing tank can be calculated; a feeding hole of the powder falling control mechanism is communicated with a discharging hole of the weighing tank, and a discharging hole of the powder falling control mechanism is communicated with a feeding hole of the powder mixing tank, so that the amount of powder entering the powder mixing tank from the weighing tank is controlled; the powder discharge control mechanism is connected with a discharge hole of the powder mixing tank so as to control the discharge of the powder mixing tank; by the adoption of the scheme, accurate weighing in the whole process can be achieved, a closed loop is achieved in each link, each link can be stably executed under the condition that the powder gravels generate static electricity, and interference of various external complex conditions is avoided.

Description

technical field [0001] The invention belongs to the technical field of powder application devices for powder inkjet adhesive printing, and particularly relates to a powder application device for powder inkjet adhesive printing. Background technique [0002] Powder inkjet bonding printing, also known as droplet jet 3D printing, inkjet 3D printing or 3DP, etc.; its working principle is that the powder coating mechanism accurately lays a thin layer of powder material on the processing platform, and then the inkjet print head is based on The cross-sectional shape of this layer sprays a layer of binder on the powder, and the thin layer of powder sprayed on the binder solidifies; then a layer of powder of a certain thickness is spread on this layer, and the print head presses the The shape is sprayed with adhesive; the layers are stacked in this way, from bottom to top, until all layers of a part are printed, and finally the uncured powder is cleaned up to obtain a three-dimension...
