[0061] Embodiment 2: Figure 10-12 As shown, an auxiliary mechanism 8 is provided. When the rack 76 descends, the rack 76 drives the connecting rod 81 to descend, the connecting rod 81 drives the sliding rod 82 to descend, and the sliding rod 82 drives the piston 84 to slide inside the slide cylinder 83. The piston 84 evacuates air from the slide cylinder 83 and the through hole 85, so that the through hole 85 is at a negative pressure, which is convenient for adsorption of the bottom surface of the consumable cylinder 6, assists in the positioning of the consumable cylinder 6, and improves the stability of the consumable cylinder 6; and when there is a lot of water vapor inside the top cover 3, the water vapor pushes the pressure plate 13, so that the pressure plate 13 flips open, and the pressure plate 13 squeezes the spring three 14, which is convenient for the water vapor to be discharged from the exhaust hole 11, thereby reducing the accumulation of water vapor inside.

[0062] Working principle: When using the device, first, Figure 1-12 As shown, the consumable cylinder 6 is placed on the top of the placement plate 77, and the mounting cylinder 719 is kept in the middle of the inner hole of the consumable cylinder 6. The consumable cylinder 6's own weight will drive the consumable cylinder 6 to descend, and the consumable cylinder 6 presses down the placement plate 77. The placement plate 77 drives the rack 76 to descend, and the rack 76 drives the gear 711 to rotate, and the gear 711 drives the fixing sleeve 712 to rotate.

[0063] Since the gear 711 is arranged symmetrically with respect to the center, the fixed sleeve 712 on one side releases the pull rope 713, and the fixed sleeve 712 on the other side drives the pull rope 713 to reel in, so that the vertical rod 715 rotates in a single direction, the pull rope 713 drives the vertical rod 715 to rotate, and the pull rope 713 drives the fixed block 716 to move, and the fixed block 716 cooperates with the blocking block 717 to compress the spring 1 718, and the spring 1 718 is used to reset the pull rope 713.

[0064] The rotation of the vertical rod 715 drives the threaded sleeve 720 to rise, and the limit block 721 slides in the limit groove 722 to limit the threaded sleeve 720. The threaded sleeve 720 drives the push block 726 to squeeze the bottom of the clamping rod 724, so that the clamping rod 724 rotates and expands to both sides. The clamping rod 724 stretches the spring 2 725 until the top of the clamping rod 724 is pressed against the side wall of the inner hole of the consumable cylinder 6, completing the fixed clamping of the consumable cylinder 6. At this time, the consumable cylinder 6 no longer drops, thereby improving the flexibility of positioning the different inner holes of the consumable cylinder 6.

[0065] As the rack 76 descends, the rack 76 drives the connecting rod 81 to descend, the connecting rod 81 drives the sliding rod 82 to descend, the sliding rod 82 drives the piston 84 to slide inside the slide cylinder 83, and the piston 84 evacuates air from the slide cylinder 83 and the through hole 85, so that the through hole 85 is under negative pressure, which facilitates the adsorption of the bottom surface of the consumable cylinder 6, assists in the positioning of the consumable cylinder 6, and improves the stability of the consumable cylinder 6.

[0066] Then close the top cover 3 and start the hot air blower 4. The hot air blower 4 blows air through the side box 5 and the vent 9 and inputs it into the top cover 3. The motor 71 rotates to drive the rotating shaft 72 and the installation box 73 to rotate. The installation box 73 drives the fixed plate 75 to rotate, so as to rotate the consumable barrel 6 for heating and curing.

[0067] When there is a lot of water vapor inside the top cover 3, the water vapor pushes the pressing plate 13, causing the pressing plate 13 to flip open. The pressing plate 13 squeezes the spring three 14, making it easier for the water vapor to be discharged from the exhaust hole 11, thereby reducing the accumulation of water vapor inside.

[0068] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
