Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "upper, lower" and "top, bottom" etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and in the case of not making a contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be interpreted as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

As shown in fig. 1-5, a scraper for 3D printer, includes knife rest 1, scraper subassembly and pivot 2, the knife rest is "ten" font, pivot fixed mounting is at the both ends of knife rest, be provided with the mounting groove on the knife rest, the scraper unit mount be in the mounting groove, the lateral wall sliding connection of scraper subassembly and mounting groove, still install on the knife rest and be used for driving the guiding mechanism that the position of scraper subassembly was adjusted in order to carry out the scraper subassembly.

Like this, the one end of pivot and the output shaft of motor, the motor drives the pivot and rotates, and then switches the scraper subassembly, and the switching process need not to shut down, raises the efficiency. When the position of the scraper needs to be adjusted, the position of the scraper component is adjusted through the adjusting mechanism, and then the scraper component is connected with the knife rest. After the scraper of scraper subassembly wearing and tearing, dismantle the scraper, maintain the scraper, the mounted position of adjustment scraper and scraper subassembly, the scraper subassembly has been installed, through guiding mechanism adjustment mounted position can, improve life, reduce cost.

The scraper components are provided with 4 scraper components which are respectively arranged on the same side of the cutter frame along the rotating direction of the rotating shaft. The production and processing are convenient, and the switching is convenient.

The scraper component comprises a first cutter holder 3, a second cutter holder 4 and a scraper 5, the first cutter holder is L-shaped, the lower ends of the second cutter holder and the scraper are abutted to the L-shaped surface of the first cutter holder, and the first cutter holder, the second cutter holder and the scraper are fixedly connected through screws 6. Through the bolt, utilize first blade holder and second blade holder to fix the scraper, be provided with waist type hole on the scraper, the position of convenient adjustment scraper, under the initial condition, the lower extreme butt of the lower extreme of scraper and first blade holder, the scraper of being convenient for makes level, and follow-up making level can go on through the spirit level.

Guide grooves are formed in two sides of the mounting groove of the tool rest, and guide blocks 7 which are in sliding fit in the guide grooves are fixedly mounted at two ends of the first tool apron. The scraper component is convenient to guide, and the movement reliability of the scraper component is improved.

The tool rest is provided with a waist-shaped hole 8, and the first tool holder is fixedly connected with the first tool rest through a bolt. The installation position of the scraper component is convenient to adjust.

The adjusting mechanism comprises a through hole penetrating through the tool rest, a screw rod 9 is installed in the through hole through a bearing, a threaded hole is formed in the lower end of the first tool apron, the screw rod is matched in the threaded hole in a screwing mode, and the number of the screw rod is at least 2. The screw rod is rotated, the first cutter seat is driven to move through the screw rod, the moving distance of the scraper component is obtained through the rotating number of turns of the screw rod, and specifically, angle scales can be arranged at the end part of the screw rod.
