Embodiment Construction

[0043] The present invention will be further elaborated and illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0044] like figure 1 As shown, an environmentally friendly powder 3D printer, its main structure includes three parts: powder spreading mechanism Ⅰ, printing nozzle Ⅱ and lifting printing platform Ⅲ. The lifting printing platform III is used as a platform for carrying molded parts 18 and unbonded powder 19 in 3D printing, while the powder spreading mechanism I and printing nozzle II are used to add leaf powder and binder to the platform respectively.

[0045] like figure 2 and 3 As shown, the lifting printing platform III includes a powder spreading baffle 11 , a printing platform 12 and a support column 13 . The powder-spreading baffle 11 is a ring-shaped and closed plate, which is surrounded by a square tube without a cover and bottom. The printing platform 12 is horizontally arranged inside the powder-spreading baffle 11...

Abstract

The invention discloses an environment-friendly powder 3D printer, and belongs to the field of 3D printing. According to the environment-friendly powder 3D printer, during fallen leaf powder printing,the designed powder 3D printer and a binder are utilized, and a printing spray head is controlled to freely move in the XY direction in a belt drive manner; and a printing bottom plane is controlledto move up and down in the Z-axis direction in a lead screw drive manner. In addition, the spray head is driven by a peristaltic pump, and uniform spraying of the binder is achieved through start-stopand speed adjustment of the peristaltic pump. A designed powder spreading tank and designed powder pavement rollers control the powder spreading process during movement in the Y direction. Accordingto the overall working sequence, the spray head carries out binder spraying on the current layer of section according to a designed 3D printing model, the axis Z descends by a printing height, the powder spreading tank and the powder pavement rollers complete one-time back and forth powder pavement in the Y direction, and the printing spray head works again to start to print the next layer. According to the environment-friendly powder 3D printer, fallen leaves can be utilized for printing meal boxes, and extremely high economic value and environment value are achieved.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to an environment-friendly powder 3D printer. Background technique [0002] With the advancement of urban greening work, a large number of urban defoliation to be dealt with during the defoliation season has become a thorny problem. The deciduous resources in urban areas with a total amount of more than 10 million tons per year are faced with the dilemma of high utilization costs and heavy pollution. [0003] At present, the main treatment mode of fallen leaves is incineration to generate electricity. The incineration process is as follows: After the road leaves are cleaned, they are sent to the waste incineration plant together with domestic garbage for incineration to generate electricity. Pollutants need to be treated for incineration to generate electricity, and the remaining solid harmful substances are solidified and then landfilled. At present, one ton of fallen leave...
