Simply stated, when there is the consumptive material in the storage tank 5, the material returning claw 25 can not support the storage tank 5, and then when changing the storage tank 5 with adding the consumptive material, the material returning claw 25 can not interfere with it, and when waiting for the consumptive material to use up, when driving the storage tank 5 to rise, the accessible material returning claw 25 takes out the consumptive material, more does benefit to the change.
In summary, the application provides a device for quickly replacing a storage tank 5, wherein a tray 14 and the storage tank 5 are lifted by the threaded fit of two screw rods 13 and a threaded sleeve 31, and the storage tank 5 is limited by a material returning claw 25 after being lifted to the end of a stroke, wherein the limiting is according to whether consumable materials exist in the storage tank 5, if the consumable materials exist in the storage tank 5, the material returning claw 25 cannot limit the storage tank 5;
After the storage tank 5 is limited by the material returning claw 25, the storage tank 5 can be replaced by related equipment or consumable materials can be added into the storage tank 5, and the material returning claw 25 is released from limiting and the storage tank 5 is reset by the weight of the consumable materials;
When the weighing plate 3 rotates, the spent storage tanks 5 are removed, and the storage tanks 5 loaded with consumable materials are installed, so that the replacement speed of the storage tanks 5 is relatively high;
wherein, drive two lead screws 13 to rotate is realized through the mode of clockwork spring 18 reserve potential energy and release after weighing fishplate bar 3 rotates and accomplishes, and then need not the power supply.
An additive manufacturing method, which adopts additive manufacturing equipment, comprises the following steps:
Step one, driving the weighing plate 3 to rotate through a motor 23, and driving the first gear 4 to do circular motion by taking an output shaft of the motor 23 as a circle center when the weighing plate 3 rotates;
Step two, when the first gear 4 rotates, the driving pipe 7 and the second gear 8 are driven to rotate through the toothed ring 6, then the reciprocating assembly is driven to work through the driving pipe 7, the screw rod 13 is driven to rotate clockwise and then rotate anticlockwise through the reciprocating assembly, and the screw rod 13 drives the tray 14 to perform vertical movement through the threaded fit with the threaded sleeve 31 so as to drive the storage tank 5 to rise vertically;
