THREE-DIMENSIONAL PRINTING DEVICE

Abstract

A three-dimensional printing device includes a top bracket, a side bracket, and a pivoting member. The top bracket includes a pair of sidewalls cooperatively defining a receiving space to receive an inkjet head. The side bracket includes a pair of sidewalls cooperatively defining a receiving space to receive the top bracket. The pivoting member includes a pair of sidewalls cooperatively defining a receiving space to receive an inkjet head. The pivoting member is rotatably mounted in the receiving space of the side bracket.

Description

BACKGROUND

1. Technical Field

The disclosure generally relates to printers, and particularly to a three-dimensional printing device.

2. Description of Related Art

Computer printers typically print on sheet media such as paper or transparencies. Some printers utilize a nozzle of an inkjet head to print on a planar surface of a workpiece. However, non-planar surfaces cannot be printed.

What is needed, therefore, is a three-dimensional printing device addressing the limitations described.

DETAILED DESCRIPTION OF THE EMBODIMENT

Referring to FIGS. 1 and 2, an embodiment of a three-dimensional printing device 10 includes a top bracket 20, a pair of side brackets 30, a pair of pivoting members 40 and a plurality of inkjet heads 50.

The top bracket 20 includes a pair of sidewalls 21 cooperatively defining a receiving space 22. A plurality of fixing holes 23 are defined in the two sidewalls 21, connecting with the receiving space 22. One or more inkjet heads 50 is received in the receiving space 22 of the top bracket 20. A plurality of fasteners 60 are received in receiving holes on the inkjet head 50 after passing through corresponding fixing holes 23 on the top bracket 20. The inkjet head 50 is thus fastened to the top bracket 20.

Each side bracket 30 includes a pair of sidewalls 31 cooperatively defining a receiving space 32. A plurality of fixing holes 33 are defined in the two sidewalls 31, connecting with the receiving space 32. The top bracket 20 is received in the receiving space 32 of the side bracket 30. A plurality of fasteners 60 are received in the fixing holes 23 on the top bracket 20 after passing through corresponding fixing holes 33 on the side bracket 30. The top bracket 20 is thus fastened to the side bracket 30.

Each pivoting member 40 includes a pair of sidewalls 41 cooperatively defining a receiving space 42. A plurality of pivoting holes 43 are defined in a first end of the two sidewalls 41. A fixing hole 44 is defined in a second end of the two sidewalls 41. One or more inkjet heads 50 is received in the receiving space 42 of the pivoting member 40. The pivoting member 40 is positioned in the receiving space 32 of the side bracket 30. A plurality of fasteners 60 are received in the pivoting hole 43 and the fixing hole 44 on the sidewall 41 after passing through corresponding fixing holes 33 on the side bracket 30. The pivoting member 40 is thus fastened to the side bracket 30.

Referring to FIG. 3, when a workpiece 70 is introduced into the three-dimensional printing device 10 by a conveyer belt 80, the inkjet heads 50 print on a top surface and side surfaces of the workpiece 70.

The location and the angle of the inkjet heads 50 can be adjusted based on printing requirements. The distance between the pair of side brackets 30 and the height of the top bracket 20 can be adjustable. Referring to FIG. 4, when a smaller workpiece 71 is introduced into the three-dimensional printing device 10 by the conveyer belt 80, the inkjet heads 50 print on a top surface and two side surfaces of the smaller workpiece 71.

It is to be understood, however, that even though numerous characteristics and advantages of various embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only; and that changes may be made in detail, especially in matters of arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
