Description

Technical Field

[0001] This utility model belongs to the field of 3D printed workpiece drying technology, specifically a rapid drying rack for cleaning 3D printed workpieces. Background Technology

[0002] 3D printed parts refer to solid components or products manufactured using 3D printing technology. 3D printing, also known as additive manufacturing, builds objects by depositing materials layer by layer, unlike traditional subtractive manufacturing (such as machining). This unique forming principle endows 3D printed parts with numerous characteristics.

[0003] Cleaning of 3D printed parts is an indispensable post-processing step in the 3D printing process. It is related to the final quality and performance of the parts. Due to the differences in materials and molding methods used in different 3D printing processes, the cleaning methods also have their own characteristics.

[0004] After cleaning, 3D printed workpieces need to be dried. In existing technologies, drying 3D printed workpieces after cleaning usually involves blowing hot air in a fixed direction to quickly dry the workpieces. However, 3D printed workpieces have various shapes, and some hard-to-reach areas are easily blocked, making it difficult to dry them quickly.

[0005] Therefore, a rapid drying rack for cleaning 3D printed workpieces is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a rapid drying rack for cleaning 3D printed workpieces, which has the advantage of blowing hot air from all directions, such as the top, bottom, and sides, to reduce dead corners of the 3D printed workpieces and improve the drying efficiency of the 3D printed workpieces.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rapid drying rack for cleaning 3D printed workpieces, comprising a base frame, wherein a hot air duct assembly is mounted on the base frame, and the hot air duct assembly is respectively connected to a rotary drive assembly and a hot air assembly;

The top duct, side ducts, and bottom duct are each equipped with an equidistant top hot air outlet, side hot air outlet, and bottom hot air outlet. A vertical pipe is fixedly connected to the center of the top of the top duct. This hot air duct assembly allows hot air to be blown towards the top, sides, and bottom of the 3D printed workpiece, reducing dead zones and ensuring effective drying.

[0009] Preferably, the base frame includes a base plate, a column is fixedly connected to the top center of the base plate, and a mesh plate is fixedly connected to the top of the column.

[0011] Preferably, the rotary drive assembly includes a drive motor, which is connected to a drive gear via a motor shaft. The drive gear meshes with a driven gear, and the driven gear is fixedly connected to a vertical pipe. This drives the hot air duct assembly to rotate around the 3D printed workpiece. In conjunction with the hot air assembly, hot air can be blown onto the 3D printed workpiece from various angles, effectively improving the drying efficiency of the 3D printed workpiece.

[0012] Preferably, the hot air assembly includes a hot air blower, the outlet of which is connected to a hot air pipe, one end of which is connected to a rotary joint, and the rotary joint is installed at the top of the vertical pipe.

[0013] Preferably, the base frame is fixedly connected to a supporting vertical plate, the top of the supporting vertical plate is fixedly connected to a supporting horizontal plate, the hot air blower is mounted on the supporting horizontal plate, and the vertical pipe passes through the supporting horizontal plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model sets up a hot air pipe assembly, which includes a top pipe, a side pipe, and a bottom pipe, so that hot air can be blown to the top, sides, bottom, and other areas of the 3D printed workpiece to reduce dead corners and ensure drying effect.

[0017] 2. This utility model, by setting up a rotation drive component and a hot air component, drives the hot air pipe assembly to rotate around the 3D printed workpiece.
