Printing module of rapid prototyping device

Abstract

The invention relates to a printing module of a rapid prototyping device, comprising a spray printing platform which has a frame and a transmission shaft arranged across the frame, a bearing seat which is arranged on the transmission shaft in a penetrating manner, and two modular liquid spray cartridges which are of the same structure and are embedded onto the bearing seat in opposite directions. Each liquid spray cartridge has a cartridge body provided with three liquid storage chambers inside. At least two liquid spray cartridges accommodate at least one identical spray printing liquid. The bottom of the cartridge body of each liquid spray cartridge is provided with a liquid spray chip, and the liquid spray chip is provided with multiple liquid supply slots which are correspondingly communicated with the liquid storage chambers, wherein the multiple liquid supply slots on one liquid spray chip and the multiple liquid supply slots on the other liquid spray chip are staggered, and the position of the tail end of the multiple liquid supply slots on one liquid spray chip is flush with the position of the top end of the multiple liquid supply slots on the other liquid spray chip. Thus, the effective length of spray printing is increased in order to implement spray printing work of rapid prototyping.

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.
