[0033] The supporting block 83 is arranged tilted.

[0034] It should be noted that when printing is performed using the metal conveyor belt 6, the metal conveyor belt 6 is guided by the auxiliary roller 82 and passes through the scraper 86. The scraper 86 is pushed by the limiting spring 85 and is tightly attached to the end face of the metal conveyor belt 6 along the inclined support block 83, thereby removing the remaining printed matter to facilitate subsequent printing.

[0036] It should be noted that when the clamping assembly 87 is in use, the lower support roller 871 is located below the metal conveyor belt 6, and the upper pressure roller 873 is located above the magnetic suction plate 61 on the inner side of the metal conveyor belt 6, so that by turning the adjusting rod 877, the worm 878 is driven to rotate, so that the worm 878 engages with the worm wheel 876, thereby driving the threaded sleeve 875 to rotate, thereby driving the corresponding screw 874 to move along the threaded sleeve 875, thereby driving the lifting block 872 to drive the upper pressure roller 873 to approach the lower support roller 871, so that it can further clamp and limit the metal conveyor belt 6, and can also flatten and adjust the cleaned metal conveyor belt 6, so as to improve printing stability.

[0037] The working principle of the magnetic hot bed platform of the conveyor-type 3D printer provided by the utility model is as follows:

[0038] When in use, the traditional soft conveyor belt is replaced with a metal conveyor belt 6 which is sleeved on the active roller 2 and the driven roller 3. Then, when printing, the servo motor 4 is used to drive the active roller 2 to drive the metal conveyor belt 6 for transmission. When conveying to the heated bed 5, the metal conveyor belt 6 and the heated bed 5 are adsorbed by the magnetic suction sheet 2 71 and the magnetic suction sheet 1 61 to conduct heat conduction. In order to reduce the resistance during transmission, a Teflon cloth resistant to high temperature and having a lubricating effect is provided between the magnetic suction sheet 2 71 and the magnetic suction sheet 1 61 as a lubricating layer 72 to achieve heat conduction while conveying and printing. When the metal conveyor belt 6 is used for printing, the metal conveyor belt 6 is guided by the auxiliary roller 82 and passed through the scraper 86. The scraper 86 is pushed by the extrusion of the limit spring 85 and is tightly attached to the end face of the metal conveyor belt 6 along the inclined support block 83 to remove the residual printed matter for subsequent printing.

[0039] Furthermore, by using the clamping assembly 87, the lower support roller 871 is located below the metal conveyor belt 6, and the upper pressure roller 873 is located above the magnetic suction plate 61 on the inner side of the metal conveyor belt 6, so that by turning the adjusting rod 877, the worm 878 is driven to rotate, so that the worm 878 engages with the worm wheel 876, thereby driving the threaded sleeve 875 to rotate, thereby driving the corresponding screw 874 to move along the threaded sleeve 875, thereby driving the lifting block 872 to drive the upper pressure roller 873 to approach the lower support roller 871, so that it can further clamp and limit the metal conveyor belt 6, and can also flatten and adjust the cleaned metal conveyor belt 6, so as to improve the printing stability.
