[ detailed description ] embodiments
Referring to the accompanying drawings of the specification, fig. 1 to 4 show that the present invention is a scraper height adjusting mechanism for a high precision 3D printer, which is provided with a scraper 10 and can drive the scraper to lift and lower to adjust the height of the scraper. In this embodiment, the scraper is a conventional scraper, and therefore, the description thereof is omitted.
The scraper height adjusting mechanism comprises a top plate 1, a driving module 2, a wedge block 3, a guide rail 4, a driving sliding block 5, a scraper guide bearing 6, a scraper height adjusting column 7, a scraper support 8 and the like.
Wherein the driving module 2 is mounted on the top plate 1. In the present embodiment, the driving module 2 is a screw driving module, and specifically includes several parts, such as a scraper lifting motor 21, a screw seat 22, a screw 23, and a moving slider 24. The screw boss 22 is held on the top plate 1. The scraper elevating motor 21 is installed at one side of the screw base 22. The screw 23 is horizontally arranged, pivotally connected to the screw base 22, and connected to and driven by the scraper lifting motor 21 to rotate. The moving slider 24 is engaged with the screw 23, and can be driven by the screw 23 to move along the screw 23.
The screw rod seat 22 is provided with a pair of inverted V-shaped guide strips 25; the inverted-V-shaped guide strips 25 are symmetrically distributed on two sides of the screw rod 23. The movable sliding block 24 is provided with an inverted V-shaped guide groove 26 matched with the guide strip 25. The movable slider 24 can be guided by the cooperation of the guide strip 25 and the inverted V-shaped guide groove 26, and the movable slider 24 is prevented from deflecting.
Further, the wedge-shaped block 3 is connected to the driving module 2 and is driven by the driving module 2 to move. In particular, the wedge-shaped block 3 is connected to the moving slider 24 of the driving module 2.
The guide rail 4 is fixedly connected with the wedge-shaped block 3, and the guide rail and the wedge-shaped block are linked. The driving sliding block 5 is matched with the guide rail 4 and can move along the guide rail 4, and the wedge-shaped block 3 can lift the driving sliding block 5.
The scraper guide bearing 6 is fixed to the mounting plate 4. The bottom end of the scraper height adjusting column 7 is connected to the driving slide block 5, the scraper height adjusting column penetrates through the scraper guide bearing 6, and the top end of the scraper height adjusting column is connected with the scraper support 8.
The working principle of the scraper height adjusting mechanism is as follows: the scraper lifting motor 21 drives the screw rod 23 to rotate, and the screw rod 23 drives the movable sliding block 24 to move; and then the wedge block 3 and the guide rail 4 which are linked and fixed on the sliding block 24 move through the sliding block. Since the wedge 3 is disposed obliquely, the guide rail 4 is also disposed obliquely. When the guide rail 4 moves obliquely, the driving slide block 5 can move along the guide rail 4, meanwhile, the driving slide block 5 can lift or pull down the scraper height adjusting column 7, the scraper height adjusting column 7 is linked with the scraper support 8, and the scraper support 8 drives the scraper to lift again.
