As an embodiment of the present invention, as shown in fig. 5, the rotating mechanism 8 includes two fixing plates 81 and a rotating shaft 82, the two fixing plates 81 are provided, and both the two fixing plates 81 are fixedly connected to the connecting plate 62, the top of the scraper 7 is provided between the two fixing plates 81, and the rotating shaft 82 is rotatably inserted between the fixing plates 81 and the scraper 7.

In operation, when installing the floater 51, the scraper 7 is arc-shaped, which can prevent the floater 51 from being installed, and the fixing plate 81 is arranged to be matched with the rotating shaft 82, so that when installing the floater 51, the scraper 7 can be rotated to be horizontal, and the scraper 7 can not prevent the floater 51 from being installed.

As an embodiment of the present invention, as shown in fig. 6, the fixing mechanism 9 includes a first fixing seat 91, a second fixing seat 92, a rotating ball 93 and fixing columns 94, the first fixing seat 91 is sleeved at a left side position of an outer surface of the refill cartridge 45, the rotating ball 93 is symmetrically and rotatably mounted at two sides of the outer surface of the first fixing seat 91, the fixing columns 94 are rotatably connected to outer surfaces of the rotating ball 93, a lower surface of the fixing column 94 is connected to the printer body 1, the second fixing seat 92 is sleeved at a right side lower end of the outer surface of the refill cartridge 45, and elastic mechanisms 10 are disposed at bottoms of the first fixing seat 91 and the second fixing seat 92.

The during operation, because feed supplement cylinder 45 level sets up, when the consumptive material liquid level in feed supplement cylinder 45 is less than bellows 43, still there is a large amount of consumptive materials in the feed supplement cylinder 45, but can not carry out the fluid infusion through bellows 43, cooperate through setting up first fixing base 91 and second fixing base 92, fix feed supplement cylinder 45, and through setting up first fixing base 91 on the left of the surface of feed supplement cylinder 45, make the inside quality based on first fixing base 91 right side consumptive material of feed supplement cylinder 45 be greater than left quality, because first fixing base 91 is connected with fixed column 94 through rotating pearl 93 again, therefore, feed supplement cylinder 45 inclines to the right side, make the consumptive material in the feed supplement cylinder 45 can flow in the bellows 43, guarantee the normal clear of fluid infusion.

As an embodiment of the present invention, as shown in fig. 6, the elastic mechanism 10 includes a circular rod 101, a second spring 102, and a limiting plate 103, one end of the circular rod 101 is fixedly connected to the second fixing seat 92, the other end of the circular rod 101 penetrates through the first fixing seat 91 and is fixedly connected to the limiting plate 103, the second spring 102 is sleeved on an outer surface of the circular rod 101, and the second spring 102 is located between the limiting plate 103 and the first fixing seat 91.

During operation, only fix feed supplement section of thick bamboo 45 through setting up first fixing base 91 to feed supplement section of thick bamboo 45 inclines to the right side, and feed supplement section of thick bamboo 45 landing easily through setting up elastic mechanism 10, before fixing feed supplement section of thick bamboo 45, pulling second fixing base 92 makes second fixing base 92 suit at the surface right side lower extreme of feed supplement section of thick bamboo 45, further fixes feed supplement section of thick bamboo 45 with this, prevents that feed supplement section of thick bamboo 45 from droing.

The using method comprises the following steps: in the printing process by utilizing photocuring equipment, consumable materials are always kept in the trough 3, the condition that a printing platform can be immersed in the consumable materials in the trough 3 can be met, the condition that the consumable materials in the trough 3 can be solidified all the time in the printing process is ensured, however, the consumable materials in the trough 3 are continuously reduced in the printing process, liquid should be timely supplemented into the trough 3, in addition, because the consumable material capacities consumed by different models are different, in order to avoid the waste of the consumable materials, when the consumable materials in the trough 3 are supplemented, when the consumable materials immerse the printing platform, the liquid supplementation should be timely stopped, through the arrangement of the feeding mechanism 4 and the adjusting mechanism 5, when printing is carried out aiming at different models, firstly, the volume of the consumable materials required by the models is estimated, the consumable materials with the corresponding volume are poured into the trough 3, the fixing knob 55 is unscrewed, the ejector rod 53 is moved upwards, the floating ball 51 can just float on the surface of the consumable materials in the trough 3, then the fixing knob 55 is screwed down, so that the position of the ejector rod 53 can be fixed, in the process that the ejector rod 53 moves upwards, the top plate 59 on the upper surface of the ejector rod 53 moves upwards along with the top plate, the top plate 59 on the lower surface of the top plate 59 is separated from the vertical cylinder 510 on the lower surface of the top plate 59, the guide rod 58 and the limiting circular plate 511 on the lower surface of the top plate 59 move upwards, the limiting circular plate 511 can limit the first spring 57, the first spring 57 is prevented from being separated from the guide rod 58, the first spring 57 between the vertical cylinder 510 and the limiting circular plate 511 is extruded and is in a compressed shape, along with the printing, the liquid level of the consumable materials in the trough 3 continuously descends, the floating ball 51 descends along with the floating ball 51, the ejector rod 53 and the vertical cylinder 510 which are connected with the floating ball 51 through the dismounting mechanism 6 descend, so that the liquid supplementing hole 56 at the bottom of the vertical cylinder 510 moves downwards to be separated from the hard tube 41, the consumable materials in the liquid supplementing tube 45 flow through the corrugated pipe 43 and the liquid supplementing hole 56, thereby replenishing the consumables in the trough 3, as the consumables in the trough 3 increase, the liquid level rises, the floating ball 51 moves upwards, the mandril 53 connected with the floating ball 51 through the dismounting mechanism 6 and the vertical cylinder 510 move upwards, the liquid replenishing hole 56 at the bottom of the vertical cylinder 510 enters the hard tube 41 again, the consumable in the material groove 3 is not replenished, with the continuous circulation, the liquid can be supplemented into the material groove 3 in time by arranging the feeding mechanism 4, the printing platform can be immersed into the consumable materials in the material groove 3, the consumable materials in the material groove 3 can be solidified all the time in the printing process, through setting up adjustment mechanism 5, can also set for different heights according to the consumptive material capacity that different models consumed, replenish in the silo 3 according to the height of setting for, replenish to setting for the height when the consumptive material, can in time stop the fluid infusion, avoid the waste of consumptive material.
