Abstract

The invention discloses a sintering forming type 3D printer for solving the problem that the occupied space of the sintering forming type 3D printer is large. The sintering forming type 3D printer comprises a material spreader and a compacting device, the compacting device comprises a pulling rope, a retracting rope and a compacting roll installed on the material spreader in a pivoted manner, andthe two ends of the pulling rope and the retracting rope are tightened and fixed to a rack; and a linear motion module is provided with a sliding rail mechanism and a rope transmission unit, the ropetransmission unit comprises a positive transmission rope, a negative transmission rope and winding wheels, the positive transmission rope and the negative transmission rope are fixed to a sliding block separately, the winding wheel corresponding to the positive transmission rope and the winding wheel corresponding to the negative transmission rope are used for pulling the sliding block to move ona guide rail in the opposite direction, and at least one of the positive transmission rope and the negative transmission rope is provided with a redundant section on the corresponding winding wheel ina winding manner. According to the sintering forming type 3D printer, the positive transmission rope and the negative transmission rope are adopted to form a pulling and retracting system, therefore,the technical problem that position misalignment occurs due to the fact that the object inertia can not be controlled when rope transmission is conducted is solved, and occupied space is small.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a sintered molding 3D printer. Background technique [0002] In the rope transmission system, since the pull rope can only be pulled in one direction, and there is motion inertia when the pulled object moves, the pulled object cannot accurately stay at the target position. [0003] In the field of printer technology, the print head needs to be able to accurately move to a certain position in a certain direction or in a plane, so the print head transmission device needs to have the function of precise movement transmission. The existing printing head transmission device mainly adopts synchronous belt pulley transmission, the synchronous belt has teeth, the driving wheel and the driven wheel both select gears, and the effect of precise transmission is realized through gear transmission. However, the manufacturing process of timing belts and gears is complicated, and the cost of p...
