Consumable connecting device for FDM type 3D printer and 3D printing equipment

Abstract

The invention discloses a consumable connecting device for a FDM type 3D printer and 3D printing equipment. The consumable connecting device comprises a base, a fixed box body and a movable box body,wherein the fixed box body is installed at one end of the base, a sliding mechanism is installed at the other end of the base, the movable box body is installed on the sliding mechanism, a heating connecting device is installed inside the fixed box body and the movable box body, a current adjusting device is installed on the outer side wall of the fixed box body, guide cavities are formed in the two ends of the fixed box body and the movable box body, guide mechanisms are installed inside the guide cavities, and heat dissipation cavities are formed in the upper ends of the fixed box body and the movable box body. The consumable connecting device can heat consumables rapidly, can achieve different heating temperatures, is suitable for heating the consumables made of various materials, can be directly installed and connected to the advancing track of the material filament consumables, cannot influence the feeding effect of material filaments, further can accelerate cooling of the consumables, and is easy to use and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a consumable connection device for FDM 3D printers and 3D printing equipment. Background technique [0002] With the development of science and technology, 3D printing technology has been developing continuously in recent years. It integrates technical knowledge of digital modeling technology, information engineering technology, material science and chemistry, mechanical structure technology, etc., and is more and more applied to various industries. In the field of work, FDM 3D printers are more and more widely used because of their system structure principle, simple operation, low maintenance cost, and safe system operation, while FDM 3D printers have high raw material utilization and long material life. The materials used are generally thermoplastic materials, such as wax, ABS, nylon, etc., which are fed in filament form. The material is heated and melted in the n...

AI Technical Summary

Problems solved by technology

[0003] The two sections of filaments of the existing FDM 3D printers are often connected by manual heating and melting of the two sections of consumables, and then trimmed by a cutter. The application number "201610488811.X" discloses a FDM3D printer consumable The connection device performs heating connection by fixing two sections of consumables, but there are still the following deficiencies: 1. When connecting, an external heating source is required, and different materials need to be melted at different temperatures, which is very troublesome; 2. In the consumables After the connection is completed, the connection device needs to be removed, which cannot be used continuously, and the connection efficiency is low; 3. There is no heat dissipation device, and it needs to be naturally cooled and shaped after the connection is completed. The cooling efficiency is low, resulting in a long connection time; 4. The use process is cumbersome, and various parts need to be connected during use, and the position of the consumables cannot be seen when inserting the consumables from the first channel and the second channel, and the problem of not being abutted together is prone to occur when connecting
