Description

A continuous conveying device applied to 3D printers

technical field

Background technique

As we all know, the idea of 3D printing originated in the United States at the end of the 19th century, but it was developed and promoted in the late 1980s; a 3D printer, also known as a three-dimensional printer, is a cumulative manufacturing technology, that is, a printer capable of rapid prototyping. It is based on the digital model file, using special wax, powdered metal or plastic and other bondable materials, and printing out these bondable materials layer by layer according to the corresponding procedures, so as to make the corresponding three-dimensional However, in the long-term practical application, it is found that due to the high temperature of the bondable material when the existing 3D printer is printing, in order to avoid the bondable material from cooling down too fast during the printing process, it is usually necessary to place the printed object A heating plate is set on the upper surface of the product platform of the three-dimensional object, so that the printed three-dimensional object can be kept warm by using the opened heating plate, so as to prevent the bottom from cooling too fast, which will affect the quality of the printed product. However, after the printing is completed, The three-dimensional object needs to be cooled on the product platform of the 3D printer. If the three-dimensional object is directly peeled off and taken away, it is very easy to cause damage to the bottom of the product hot-bonded on the surface of the product platform, resulting in waste products. Therefore, the existing 3D printers are equipped with a printing platform bracket with a heating plate as the product platform. When the printing is completed, the producer turns off the heating plate and moves the printing platform bracket so that it simultaneously drives the heating plate and the printed 3D object away from the printing area, and then after the printed three-dimensional object is cooled, it is peeled off from the upper surface of the heating plate and taken away, which leads to the need for an active printing platform bracket to be set in the existing 3D printers for corresponding printing Operation, that is, the existing 3d printer can only print one product at a time, and it can only print the next product after the first printed product is taken away from the product platform, and this setting significantly reduces the printing capacity of the 3d printer. Efficiency. In addition, since the printed products need to be peeled off manually, the existing 3D printers must have people on duty on site during operation.
