Printing module of rapid prototyping unit

Abstract

The present invention relates to a printing module of a rapid prototyping device, comprising: a spray printing platform having a frame body and a transmission shaft straddling the frame body; a bearing seat pierced on the transmission shaft; Cassettes are fitted on the bearing seat in opposite directions. Each liquid spray cassette has a cassette body with three liquid storage chambers inside. At least one of the same spray printing liquid is placed in the at least two liquid spray cassettes. The bottom of the box body of the liquid box is provided with a liquid spray chip, on which there are a plurality of liquid supply tanks, which are respectively communicated with the liquid storage chambers. The plurality of liquid supply tanks are arranged in dislocation, and the positions of the ends thereof are aligned with the positions of the tops of another plurality of liquid supply tanks, so as to promote the extension of the effective printing length to implement the rapid prototyping printing operation.

Description

【Technical field】 [0001] The invention relates to a rapid prototyping device, in particular to a printing module of the rapid prototyping device which has two modularized liquid spray boxes with the same structure, which are fitted in opposite directions to the bearing seat. 【Background technique】 [0002] Rapid prototyping technology (RP technology for short) is developed based on the concept of constructing layers of pyramid-like stacking. Automatically and quickly convert the design scheme of any complex shape into a 3D solid model, which greatly shortens the research and development cycle of new products and reduces the cost of research and development, and can ensure the time to market of new products and the first-time success rate of new product development, rapid prototyping Technology provides a more complete and convenient product design communication tool for technical personnel, as well as between technical personnel and enterprise decision makers, product users ...

Problems solved by technology

[0006] However, when the rapid prototyping printing operation of this 3D object is implemented, in addition to containing black and color inks, the liquid jet box 12 needs to additionally contain high-viscosity adhesives to bond the construction materials, and then It can be stacked layer by layer to form a 3D object. Therefore, the traditional rapid prototyping device needs to be equipped with an additional carrier and a liquid spray box to accommodate high-viscosity adhesives. In this way, the overall inkjet printing module 1 The volume increases, and at the same time increases the cost of the carrier and the spray box

[0007] In addition, the position of the inkjet chip of the traditional liquid jet cartridge 12 is the same, so the printing stroke is also fixed to match the length of the nozzle hole on the inkjet chip, and the printing speed cannot be accelerated.
