Printing tray push-out structure applied to double-laser printer

Abstract

The invention discloses a printing tray push-out structure applied to a double-laser printer in the technical field of 3D printing. The printing tray push-out structure comprises a processing chamber, a powder recycling and containing cavity, a powder supply mechanism, a shell and a powder recycling box, and is characterized by further comprising a processing mechanism, a plate supply mechanism, a cleaning mechanism and a discharging mechanism, wherein the powder supply mechanism, the processing mechanism and the powder recycling and containing cavity are sequentially and horizontally arranged in the processing chamber, and the powder recycling box is fixedly arranged below the processing chamber; the cleaning mechanism is arranged behind the processing mechanism, and the plate supply mechanism and the discharging mechanism are arranged on the two sides of the cleaning mechanism respectively; and the shell is fixedly arranged on the outer side of the processing chamber. After one workpiece is processed by equipment, the next workpiece can be processed in a short time. Compared with a traditional mode that the workpiece needs to be completely taken down and then remounting can be conducted, the working efficiency of the printer is greatly improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a printing tray push-out structure applied to a dual laser printer. Background technique [0002] 3D laser printers usually lay the raw materials on the printing tray, and then use the laser head to irradiate the raw materials, sinter the raw materials, and then process the corresponding products. Harmful gases will be generated during the processing, so the printing tray is usually enclosed by a machine cover. Generally speaking, the printing tray is usually in the middle of the hood, and the products on the printing tray need to be taken out after printing is completed; because the printing is done by sintering the raw material, the printed workpiece will be firmly stuck to the printing tray, Therefore, the equipment usually adopts a detachable printing tray. After the processing is completed, the printing tray is directly disassembled together with the products on it. [...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a printing tray push-out structure applied to dual laser printers, to solve the above-mentioned background technology that the traditional printing tray is often locked by screws, and after the printing tray is disassembled once, it needs to be manually clamped again , the whole process needs to be carried out manually, the efficiency is low, and the installation accuracy cannot be well guaranteed; moreover, during the disassembly process, it is necessary to open the cover to clean the powdery raw materials on the printing tray, which is easy to make the powdery Raw materials float out of the equipment, pollute the working environment, and easily cause harm to the staff and equipment
