3D printer head structure

Abstract

The invention discloses a 3D printer head structure. The 3D printer head structure comprises a turning rack, a casing and a fixed bracket, wherein a base is mounted on the turning rack; pull rods arefixed at two ends of the top of the base; screw holes are uniformly formed in the turning rack; an adjusting bolt is fixed on one side of the base and connected with the screw holes; fastening blocksare fixed at two ends of the turning rack; clamp slots are uniformly formed in the fastening blocks; the fixed bracket is fixed at the bottom end of the turning rack; connecting blocks are fixed at two ends of the fixed bracket; a heat conducting layer is arranged between a heating cavity and a cylinder; a feeding pipe is mounted at the top end of a piston, and the bottom end of the feeding pipe vertically penetrates through the piston to extend into the cylinder. The turning rack is mounted, and the screw holes are uniformly formed in the turning rack, so that the screw holes and adjusting bolt are connected, the base is fixed on the turning rack, change of the spraying direction of a spray nozzle is realized, and printing of the printer is convenient.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printer head structure. Background technique [0002] A 3D printer, also known as a three-dimensional printer, is a digital model file based on the use of special wax, powdered metal or plastic and other bondable materials to manufacture three-dimensional objects by printing layers of adhesive materials. At this stage, three-dimensional Printers are used to manufacture products, and the technology of constructing objects by layer-by-layer printing. The principle of 3D printers is to put data and raw materials into 3D printers, and the machine will build products layer by layer according to the program. At present, 3D printers are common Most of the print heads of 3D printers are fixed, and in order to ensure the printing accuracy of the printed items, the diameter of the spray hole of the nozzle should not be too large, usually 1.75mm.

[0002] A 3D printer, also known as a three-dimensional printer, is a digital model file based on the use of special wax, powdered metal or plastic and other bondable materials to manufacture three-dimensional objects by printing layers of adhesive materials. At this stage, three-dimensional Printers are used to manufacture products, and the technology of constructing objects by layer-by-layer printing. The principle of 3D printers is to put data and raw materials into 3D printers, and the machine will build products layer by layer according to the program. At present, 3D printers are common Most of the print heads of 3D printers are fixed, and in order to ensure the printing accuracy of the printed items, the diameter of the spray hole of the nozzle should not be too large, usually 1.75mm. Although this can improve the printing accuracy, the printing speed is too slow. When using it to print a medium or large model, it takes more than ten days or even longer. When the reliability of the 3D printer and the associated computer cannot be guaranteed for a long time, many problems such as the printing time limit in the middle often occur, which is not reliable enough. Practical. At the same time, the spraying direction of the traditional nozzle is mostly fixed. The use of printing has certain limitations, which is not convenient for the use of the printer. At the same time, the structure of the traditional printer head is mostly fixed by screws. When the device fails, it needs to be fixed. The screwdriver removes the screw, which makes maintenance extremely inconvenient. At the same time, the distance between the nozzle of the traditional printer and the printing material carrier is mostly fixed, but in the actual process, the distance between the two has a certain impact on the printing effect.
