3D printing cake technology is a technology that combines 3D printing technology with traditional cake making methods to quickly produce cakes with personalized characteristics. The existing 3D printing cake machine equipment mainly uses the principle of extrusion molding to print, and the forming platform mainly moves in the vertical direction. During the printing process, the printing of each layer's outline can only be done through the nozzle alone in the XY plane. Although this method has a simple structure, it is difficult to guarantee the accuracy of complex contours and shapes in the cake making process, especially when printing contours and shapes with arc characteristics, which is not conducive to The quality of formed cakes is not conducive to the application and promotion of 3D printing cake technology in the market.

Utility model content

The purpose of this utility model is to solve the problems existing in the prior art, to provide a rotatable forming platform for 3D printing cake machine with simple structure, convenient operation, which can significantly improve the manufacturing precision and surface quality of the processed cake model device.

There is a forming platform that can rotate along the horizontal direction driven by a servo motor.

The further technical solution of the utility model also includes: two Z guide rods are symmetrically arranged upright on both sides of the molding machine base, and the Z guide rods are separated on both sides of the Z-direction ball screw and pass through the forming platform mounting frame.

The further technical solution of the utility model also includes: the servo motor for driving the rotation of the forming platform is arranged under the mounting frame of the forming platform, the drive shaft passes through the mounting frame of the forming platform and is connected with the center of the forming platform, and a bottom of the forming platform is provided There are four universal ball bearings symmetrically installed on the mounting frame of the forming platform, and the balls of the four universal ball bearings are matched with the concave raceways at the bottom of the forming platform.

The further technical solution of the utility model also includes: the support mode between the mounting frame of the forming platform and the forming platform is a symmetrical support mode of universal ball bearings, and the distribution characteristics of the universal ball bearings are evenly and symmetrically distributed at a distance of 90° between them. .

In actual work, the 3D printing cake machine completes the layer-by-layer printing of cake model products through the rotation of the Z-direction ball screw on both sides of the molding machine base. The movement coordination between the nozzle and the forming platform is determined. When printing the circular or arc-shaped pattern model on the surface of the cake, the forming platform makes a certain rotational movement driven by the servo motor of the forming platform. Perform coordinated movements to improve the forming accuracy and quality of printed cakes.

Compared with the prior art, the rotatable forming platform device described in the utility model has simple principle, compact structure, and convenient operation. When printing a cake with a 3D printing cake machine, it can pass between the rotation of the forming platform and the movement of the printing nozzle. Cooperate with each other to significantly improve the running accuracy of the printing track, thereby significantly improving the printing quality of the 3D printing cake machine, especially when printing round cakes or shapes with arc characteristics, which is conducive to improving the quality of processed cakes.
