Powder flatly-sweeping device of 3D printer

Abstract

The invention relates to the technical field of flatly-sweeping device, in particular to a powder flatly-sweeping device of a 3D printer. The powder flatly-sweeping device of the 3D printer comprisesa box and a first motor; the first motor is fixedly connected to the left end of the box; a multi-groove cam is fixedly connected to the tail end of a spindle of the first motor; a cam sliding block is slideably connected to the inner side of the bottom end of the multi-groove cam; sliding grooves which are symmetrically disposed up and down are formed in the rear end surface of the box; a first sliding block is fixedly connected to the rear end surface of the cam sliding block; the first sliding block is slideably connected with the upper sliding groove; a fixing seat is slideably connected to the bottom end of the cam sliding block; and a rack is slideably connected to the bottom end of the fixing seat. By arranging the multi-groove cam, the cam sliding block, the fixing seat and the first sliding block, the adopted multi-groove cam mechanism is compact in structure and operates stably, powder can be flatly swept by well adopting the device, subsequent machining production use is convenient, the economic benefits are giant, the market prospects are wide, and the device is worth applying and popularizing.

Description

technical field [0001] The invention relates to the technical field of sweeping devices, in particular to a powder sweeping device for a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. To print a layer of adhesive material to make a three-dimensional object, the powder needs to be leveled before printing, and the quality of the powder will affect the cost of production. Therefore, the powder leveling device of the 3D printer The demand is growing day by day. [0003] Most of the powder sweeping devices of 3D printers on the market use the screw slide table to spread the powder, the efficiency is low, and its use effect is not ideal, not only the low efficiency will affect the use of printing, but also may It will inc...

Problems solved by technology

[0003] Most of the powder sweeping devices of 3D printers on the market use the screw slide table to spread the powder, the efficiency is low, and its use effect is not ideal, not only the low efficiency will affect the use of printing, but also may It will increase the cost of production. Most of the powder leveling devices of traditional 3D printers can only be leveled left and right or front and back. The leveling efficiency is low, which seriously affects the subsequent production and use. Therefore, a 3D printer powder leveling device
