In order to keep the heat of a sealed cavity, the inside of the cavity is usually prevented from being opened as much as possible, and the circulation of the inside air and the outside air is reduced, so that the heat preservation effect is achieved, in the application field of the scheme, the problem in the printing cavity is kept, meanwhile, some mechanical electronic elements are arranged to drive the printing platform in the printing cavity to achieve the effect of moving the printing platform, the existing scheme can be arranged only by sacrificing some heat, the scheme is adopted, the printing process can be ensured to be carried out, but the consumed energy is multiple times that in the sealed cavity, so that the following technical scheme is provided for solving the technical problem:

referring to fig. 1-4, a printing chamber sealed cabin of a 3D printer includes: a chassis housing 1; the printing device comprises a printing chamber 2 positioned in the chassis shell 1, a printing platform 21 movably connected in the printing chamber 2, a door 22 hinged with the printing chamber 2, and sealing covers 23 arranged on two sides of one end, close to the door, of the printing chamber 2; case shell 1 with be provided with an empty drum district A between the printing cavity 2, be provided with vertical migration structure 3 in the empty drum district A, vertical migration structure 3 locking is fixed with interior buckle 34, interior buckle 34 is the opening orientation print the U type structure of 2 one sides of cavity, and interior buckle 34 run through sealed cowling 23 with print platform 21 locking is fixed.

It should be noted that, according to the present invention, an empty drum area a is disposed between the chassis housing 1 and the printing chamber 2, wherein the empty drum area a is used for accommodating the vertical moving structure 3, and can enable the vertical moving structure 3 for providing power to be close to the printing chamber 2 as much as possible, so as to reduce the space occupied by the apparatus, and in other embodiments, the chassis housing 1 can be made into a sealed box, so that even after heat is released from the printing chamber 2, the heat can stay in the empty drum area a and be retained between the printing chamber 2 and the chassis housing 1, so as to form a heat preservation effect on the printing chamber 2, and compared with directly releasing the heat to the external space, a partial energy saving effect can be achieved.

Firstly, the vertical moving structure 3 is a power structure, at least comprises an electronic element for starting and a mechanical element for transmission, in a fine printing link of 3D printing, the requirement on the moving precision of the vertical moving structure 3 is high, if the vertical moving structure is in a high-temperature environment, the electronic element and the mechanical element are inevitably damaged (on the premise of considering the cost, some high-level components are not used), so the vertical moving structure 3 is externally arranged, and then, in the case that the vertical moving structure 3 is externally arranged, the vertical moving structure needs to form a link with the printing platform 21 inside the printing chamber 2, so the vertical moving structure is inserted into the printing chamber 2 through an inner buckle plate 34, wherein in order to reduce the area size of the components inserted into the printing chamber 2 and accordingly reduce the possible ventilation surface, the inner buckle plate 34 is in a U-shaped structure, the transverse part of the U-shaped structure is connected with the vertical moving structure 3, and the two parts extending longitudinally are inserted into the printing chamber 2.

In order to avoid the up-and-down movement of the inner clip 34 which protrudes into the printing chamber 2, the printing chamber 2 must be opened with a hole, and in order to close the part of the opening, the position of the opening is sealed by the sealing cover 23, but since the printing chamber 2 is actually opened with a hole, the movement of the inner clip 34 is not affected, and thereafter, the bellows cover 232 is provided inside the sealing cover 23, and the inner clip 34 penetrates the bellows cover 232, and when the inner clip 34 is fixed, the bellows of the bellows cover 232 tightly clamps the upper and lower ends of the inner clip 34, isolating the printing chamber 2 from the empty drum area a, and when the inner clip 34 moves up or down, the bellows of the bellows cover 232 is pressed, and at the same time, the bellows of the bellows cover 232 moves along with the inner clip 34, and no space is left.

The structure of the organ cover 232 is a specific structure that can be found in a well-known website such as Baidu website, and will not be described in detail here.

In other embodiments, when the inner buckle plate 34 is adjusted to the middle position of the organ cover 232, the inner buckle plate 34 is adhered to the organ cover 232 through adhesive glue, so that when the inner buckle plate 34 drives the printing platform 21 to move, the space between the inner buckle plate and the organ cover 232 is in a sealed state, and the organ cover 232 has certain elasticity due to the fact that the inner buckle plate 34 is adhered to the middle position, the structure of the organ cover 232 cannot be damaged when the inner buckle plate 34 moves to the bottommost part or the topmost part.

In this embodiment, since the high-precision movement needs to be maintained, the vertical moving structure 3 includes a motor (not shown in the figure) fixed at the bottom of the chassis housing 1, a screw rod 32 fixed above the motor, a movable nut 33 screwed on the periphery of the screw rod 32, and an inner buckle plate 34 locked on the movable nut 33, when the motor rotates, the screw rod 32 is driven to rotate, so that the movable nut 33 on the screw rod 32 rotates, and the movable nut 33 drives the inner buckle plate 34 to move up and down when rotating, and since the precision of the screw rod 32 is high, the precision of the movement of the inner buckle plate 34 is also high, and can be matched with the high precision of printing.

In other embodiments, the inner buckle plate 34 can be driven to move by using a push rod motor, a linear motor and other structures capable of moving linearly.

The upper half of the sealing cover 23 is an organ cover 232, which is intended to adapt to the movement of the gusset plate 34, and since the lower half of the sealing cover 23 does not need to give way to the gusset plate 34, the lower half of the sealing cover 23 is a solid cavity 231, the solid cavity 231 and the organ cover 232 form a square cavity, the bottom of the organ cover 232 is connected with the solid cavity 231, the organ cover 232 is communicated with the chassis housing 1, and it needs to be emphasized that the coverage range of the organ cover 232 is at least larger than the movement range of the gusset plate 34, that is, the movement range of the printing platform 21.

The organ cover 232 needs to be cleaned frequently, so the organ cover 232 needs to be detached frequently, in order to reduce difficulty in detaching the organ cover 232, the bottom and the top of the printing chamber 2 are both provided with the fixed magnets 24, the upper end and the lower end of the sealing cover 23 are both provided with the matching magnets 233, the matching magnets 233 are movably connected with the fixed magnets 24, when detaching is needed, the sealing cover 23 is directly detached entirely, after washing and drying, the matching magnets 233 of the sealing cover 23 can be directly matched with the fixed magnets 24, an accurate positioning and fixing effect can be achieved, and the difficulty in detaching and the difficulty in finding the fixing point again after detaching are not needed.

After the problem of the movement of vertical movement structure 3 has been solved, the thermal insulation performance of printing cavity 2 itself also needs to be required, otherwise under the fast prerequisite of metal heat dissipation, the problem in the printing cavity 2 can't be preserved, so in order to improve the heat preservation effect of printing cavity 2, printing cavity 2 is a metal cavity, printing cavity 2 includes the three-layer at least, from inside to outside in proper order respectively be rock wool layer 27, silica gel layer 25, metal level 26, wherein, the inlayer is rock wool layer 27 structure, can furthest preserve the heat, and in order to prevent rock wool layer 27 direct and metal level 26 laminating, separate through a silica gel layer 25 between the two again to this reaches that the skin has metal level 26 to protect, the inlayer has rock wool layer 27 to keep warm, and the centre has silica gel layer 25 to carry out the complete heat preservation, protection architecture of keeping apart.
