Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The utility model provides a get rid of device that 3D printed dental model supported, combines fig. 1 to 2 to show, includes platform 1, connecting rod 2, connecting block 3, fixing clip 4, biax step motor 5, spiller 6, guide rail 7, belt drive 8, conveyer belt 9, first live-rollers 10, second live-rollers 11, bracing piece 12.
The device for removing the 3D printing dental model support is arranged on the platform 1 and keeps the parallel direction. The belt transmission mechanism 8 is arranged in parallel with the platform 1, the belt transmission mechanism 8 comprises a pair of conveyor belts 9, and the conveyor belts 9 are arranged above the top end face of the platform 1 and are parallel to the platform 1. The front end and the rear end of the conveyor belt 9 are respectively sleeved with a first rotating roller 10 and a second rotating roller 11, the first rotating roller 10 is connected with a support rod 12 through a bearing, and the support rod 12 is perpendicular to the conveyor belt 9; the other end of the support rod 12 is fixedly connected with a fixing clip 4 for conveniently installing the belt conveying mechanism on the platform 1.
