Problems solved by technology

There are defects in the existing technology: 1. Stop the model being printed, and the position of the model may deviate, which will affect the printing effect
2. In the process of replacing raw materials, the feeding will be incomplete, and the extrusion device will produce air bubbles to affect the printing effect
3. When changing the material, the melted material extruded during the feeding process melts onto the printed object, affecting the appearance of the print; 4. Stopping the printer to change the material causes a waste of printing time
5. When changing the material, the material waste caused by the molten material extruded during the feeding process

Embodiment Construction

[0019] like figure 1 , figure 2 and image 3 As shown, a 3D printing plastic material welding device includes a pliers body 1, two fixed blocks 5 are connected to the front end of the pliers body 1, and one or two semicircular openings 4 are opened on the inner side of each fixed block 5. When the two fixed blocks 5 are closed, the semicircular openings 4 on the two fixed blocks 5 are closed to form a closed and hollow melting tank, which is used for fusion welding of 3D printing plastic materials, and each fixed block 5 is provided with A temperature control device. The temperature control device includes a heating device. The heating device includes a heating hole 3 opened in the fixed block 5 and one end is open. The heating hole 3 is used for placing a heating rod. The temperature control device also includes a temperature monitoring hole 2 opened in the fixed block 5 and opened at one end. The temperature monitoring hole 2 is used for placing a temperature detector. ...

Abstract

The invention discloses a welding device for 3D printing plastic material. The device comprises a pliers body; the front end of the pliers body is connected with two fixed blocks; one or two semi-circular opening(s) is / are formed at the inner side of each fixed block; when the two fixed block are closed, the semi-circular openings formed in the two fixed blocks are closed, thus forming a sealed hollow fusing groove; the fusing groove is used for fusion welding of the 3D printing plastic material; each fixed block is provided with a temperature control device. By adoption of the welding device for the 3D printing plastic material, the printing material can be replaced in the printing process without stopping a 3D printer, so that the time is saved and the model precision is improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing plastic material welding device. Background technique [0002] 3D printers using FDM technology generally use thermoplastic materials, such as PLA, ABS, PLA flexible, polyvinyl alcohol (PVA), nylon, etc. At present, the popular specifications on the market are two specifications with a diameter of 1.75mm and 3mm. The weight of a single roll of material is about 0.75kg. The use process is as follows: the material is heated and melted in the extruder through the feeding device, and the nozzle follows the section profile of the part and fills it. The trajectory moves, and the molten material is extruded at the same time. The material solidifies rapidly and bonds with the surrounding materials, so as to accumulate and print out the required objects. [0003] When the material is too short or the raw material is exhausted during the printing process, the...
