Description of the embodiments
The following describes the embodiments of the present utility model in further detail with reference to the drawings.
From fig. 1 to fig. 6, it can be seen that a dustproof device for a lead screw of an engraving machine comprises a lead screw 2 assembly, wherein the lead screw 2 assembly comprises a box body 1 with an opening at one side, the lead screw 2 is rotationally arranged in the box body 1, a driving block 3 is connected to the lead screw 2 in a threaded manner, two ends of the box body 1 are provided with storage boxes 4, a rotating shaft 5 is rotationally arranged in the storage boxes 4, a dustproof cloth 6 is wound on the rotating shaft 5, the outer end of the dustproof cloth 6 is connected to the driving block 3, and the dustproof cloth 6 can be stored in the rotating shaft 5 when the driving block 3 moves on the lead screw 2.
In the specific use of the present utility model,
fix dustproof cloth 6 tip on drive block 3, lead screw 2 can drive pivot 5 and rotate when rotating, accomodate dustproof cloth 6 simultaneously when drive block 3 removes, can prevent that dustproof cloth 6 from stacking in lead screw 2 outside, can enough protect lead screw 2 not receive the influence of dust, can in time accomodate dustproof cloth 6 again, avoid influencing the job site.
For realizing the synchronous rotation of pivot 5 when lead screw 2 rotates, receiver 4 tip is equipped with motor 7, is equipped with transmission shaft 8 between motor 7's output shaft and lead screw 2, is fixed with first bevel gear 9 on the transmission shaft 8 coaxial, and first bevel gear 9 meshing has second bevel gear 10, and second bevel gear 10 coaxial is provided with first straight gear 11, and first straight gear 11 meshing has the second straight gear 12 that sets up coaxial with pivot 5, constitutes motor 7 and drives pivot 5 pivoted structure, and the pivot 5 at lead screw 2 both ends turns to in opposite directions.
The motor 7 drives the screw rod 2 to rotate, and simultaneously the rotating shafts 5 are rotated through the transmission of the first bevel gear 9, the second bevel gear 10, the first straight gear 11 and the second straight gear 12, and the rotating shafts 5 on two sides are opposite in rotation, so that the dustproof cloth 6 on one side is stored in the dustproof cloth 6 on the other side and is unfolded when the screw rod 2 rotates.
The rotating speed of the rotating shaft 5 is matched with the moving speed of the driving block 3, so that the moving of the driving block 3 can be matched with the retraction of the dustproof cloth 6, and the dustproof cloth 6 cannot be too tight or too loose.
