AI Technical Summary

Technical Problem

When existing 3D printers produce plastic workpieces, their natural cooling efficiency is low, which makes the workpiece temperature difficult to deal with, and the bottom bearing capacity is insufficient and it is easy to collapse, affecting production efficiency.

Method used

A workpiece cooling mechanism for 3D printers is designed, which sprays upward air flow through multiple air nozzles to accelerate air circulation and promotes solidification of molten plastic; after printing, the motor is used to drive the support plate and workpiece to rotate, and the fan blows the air to accelerate cooling.

Benefits of technology

The curing and cooling process of workpieces is accelerated, the 3D printing rate and the quality of workpieces are improved, the collapse and damage are avoided, and the production efficiency is improved.

Abstract

The workpiece cooling mechanism comprises the 3D printer, a supporting plate is movably installed on a base of the 3D printer, a fixing base is fixedly connected to the top of the supporting plate, a bearing plate is rotatably installed on the top of the fixing base, a plurality of lug plates are fixedly connected to the edge of the supporting plate, and electric push rods are installed on the tops of the lug plates. A first air pipe is installed at the output end of the electric push rod and provided with a plurality of first air nozzles, a first draught fan used for ventilating the first air pipe is installed at the position, on one side of the fixing base, of the top of the supporting plate, a mounting frame is installed at the top of the rear end of the 3D printer base, a second draught fan is installed at the top of the mounting frame, and the output end of the second draught fan is connected with a second air pipe penetrating through the mounting frame. And a plurality of tuyeres II are arranged on the air pipe II. According to the utility model, the curing speed of molten plastic can be accelerated by accelerating the circulation of air around a printed workpiece, so that the printing speed can be improved, and the cooling of the workpiece can be accelerated by rotating the workpiece and blowing air to the workpiece.
