A 3D printing pen for opening and closing arc door

Abstract

The invention discloses a 3D printing pen with circular arc doors opened and closed for material supplement. The 3D printing pen with the circular arc doors opened and closed for material supplement comprises a penholder body. An opening groove penetrating inside and outside is formed in the penholder body. The opening groove is at an angle of 90 degrees. An annular rotating groove is formed in the inner cylindrical surface of the penholder body. The upper and lower side walls of the rotating groove are separately aligned to the upper and lower side walls of the opening groove. An open-closedloop matched with the rotating groove is rotatably arranged between the upper and lower side walls of the rotating groove. An opening is formed in the open-closed loop, and the angle of the open-closed loop is more than 270 degrees and less than 360 degrees. A feeding device is detachably arranged at one end of the inner cylindrical surface of the open-closed loop. An upper feeding pipe and a lower feeding pipe are arranged in the penholder body. The upper feeding pipe and the lower feeding pipe are distributed up and down, a conical surface is formed in the lower end of the upper feeding pipe, and an inward concave conical concave surface is formed in the upper end of the lower feeding pipe. Two feeding modes of external and internal are achieved, the wide application range is achieved, and raw materials are conveniently supplemented in the internal feeding mode.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a 3D printing pen for opening and closing an arc door. Background technique [0002] The 3D printing pen is based on 3D printing technology, using hot-melt PLA, ABS and other plastic filaments to extrude the required 3D products. In the prior art, 3D printing pens are generally supplied externally, so that the scope of use is limited, and it cannot really be carried around like a pen and used at any time. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a 3D printing pen that can open and close a circular arc door in order to solve the technical problem that the existing 3D printing pen needs to be supplied externally due to its small scope of use. [0004] The technical solutions of the present invention to solve the above technical problems are as follows: a 3D printing pen for opening and closing an arc door, comprising a pen body; a hollow spa...
