Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to a sealing cavity mechanism for a 3D printer. Background Art

[0002] 3D printing, also known as additive manufacturing, is a technology that creates physical parts based on three-dimensional CAD data by adding material layer by layer. The historical development of 3D printing technology has been one of continuous advancement and expansion. From early rapid prototyping techniques to its current widespread application, 3D printing technology has found applications in design and manufacturing fields such as jewelry design, footwear design and manufacturing, industrial design, architectural design, engineering design and construction, and automotive design and manufacturing, as well as in medical fields such as aerospace and dentistry.

[0003] Announcement No. (CN210121966U) discloses a sealing chamber mechanism for a 3D printer. When the sealing belt moves in the slide groove, the sealing belt can isolate the sealing chamber from the outside world, so that the sealing chamber is not connected to the outside world, making the sealing effect of the sealing chamber good. However, the sealing effect between the switch door and the front side plate in the above device is not good, which still affects the sealing effect of the sealing chamber and needs to be improved.

The electric push rod 211 extends and drives the movable block 212 and the closed door 213 to move forward. The closed door 213 moves forward and separates from the printing box 201, and the motor 205 is started. The motor 205 drives the gear 207 to rotate through the rotating shaft 206. The rotating gear 207 rises under the action of the rack 203, and the lifting shell 204 begins to rise along the fixed frame 202. The lifting shell 204 drives the fixed block 210 to rise through the lifting sleeve 208 and the lifting rod 209, and the closed door 213 rises accordingly. When the lower surface of the closed door 213 is aligned with the upper surface of the printing box 201, the motor 205 stops running, thus completing the opening of the closed door 213. When the closed door 213 is not opened, the sealing gasket 214 on the closed door 213 is in a compressed state, which effectively improves the sealing performance of the closed door 213, thereby further improving the sealing effect of the sealed cavity in the printing box 201.

[0029] In the present utility model, a reinforcement mechanism 3 is installed at the rear of the printing mechanism 2, and the reinforcement mechanism 3 includes a fixing rod 301, a fixing plate 302 welded to the rear of the fixing rod 301, a cylinder 303 fixedly installed at the rear of the fixing plate 302, and a clamping block 304 fixedly installed at the telescopic end of the cylinder 303; the cylinder 303 and the fixing plate 302 are connected by bolts, and the clamping block 304 is welded to the cylinder 303; after the closed door 213 stops rising, the cylinder 303 is started, and the operation of the cylinder 303 drives the clamping block 304 to be inserted into the clamping groove on the rear surface of the fixed frame 202, thereby reinforcing the lifting shell 204 and further improving the stability of the closed door 213.

[0030] The motor 205 is then started, and the motor 205 drives the gear 207 to rotate through the shaft 206. The rotating gear 207 rises under the action of the rack 203, and the lifting shell 204 begins to rise along the fixed frame 202. The lifting shell 204 drives the fixed block 210 to rise through the lifting sleeve 208 and the lifting rod 209, and the closed door 213 rises accordingly. When the lower surface of the closed door 213 is level with the upper surface of the print box 201, the motor 205 stops running, thus completing the opening of the closed door 213. Then the cylinder 303 is started, and the cylinder 303 drives the card block 304 to insert into the card slot on the rear surface of the fixed frame 202. In this way, the lifting shell 204 is reinforced, further improving the stability of the closed door 213.
