6. The 3D printing automatic take-up and roll-up device of claim 5, wherein: guide blocks are fixedly connected to the left end and the right end of the front side surface of the storage box respectively, and a vertical chute penetrating vertically is formed in the guide blocks; the left end and the right end of the bottom surface of the vertical supporting plate are respectively arranged on the vertical sliding rods, and the vertical sliding rods and the second racks extend into the vertical sliding grooves and form sliding pairs.
7. The working method of the 3D printing automatic fetching and paper rolling device is characterized by comprising the following steps of: comprising the steps of adopting the 3D printing automatic taking and rolling paper device as claimed in any one of claims 1 to 6, and comprising the following steps:
in an initial state, the printing platform is positioned below the 3D printer nozzle, the vertical supporting plate is positioned at the uppermost end, and the 3D printer nozzle prints products on the printing platform;
step S1: after printing is finished, the traversing motor is started, the printing platform and the printed product are driven to traverse to the upper side of the storage box through the first gear and the first rack, then the lifting motor is started, and the vertical supporting plate is driven to descend to the position that the bottom surface of the pushing shovel is flush with the top surface of the printing platform through the second gear and the second rack;
step S2: the traversing motor is reversely started and drives the printing platform to translate towards the spray head of the 3D printer through the first gear and the first rack, and the shovels are pushed to shovels the pattern paper and the printed products on the printing platform into the storage box in the translation process; meanwhile, in the moving process, as the roll paste roller is pressed on the printing platform, the textured paper on the roll paste roller is stuck on the surface of the printing platform along with the movement of the printing platform;
step S3: when the printing platform translates to the initial position, the driving motor is started, and the driving motor drives the cutting saw blade to move downwards to cut off the textured paper through the screw rod and the nut;
step S4: the driving motor is reversely started and drives the cutting saw blade to move upwards to the original position through the screw rod and the nut; the lifting motor is reversely started and drives the vertical supporting plate to lift to an initial position through the second gear and the second rack;
step S5: and (4) continuously printing the product on the printing platform by the 3D printer nozzle, and repeating the steps S1 to S4.
