DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Depend on Figure 1-5 The present invention discloses a 3D printing work box, including a shell 1, a printing table 2 capable of moving forward and backward is arranged in the shell 1, and how the printing table 2 can move forward and backward is described in detail in the prior art, and the present application will not describe it again, the upper end of the printing table 2 is provided with a groove, a supporting base 3 capable of moving up and down is arranged in the groove, a plurality of molding tables arranged in layers are placed on the supporting base 3, and the product is printed on the molding table,

[0025] The forming table is a thin plate structure, and multiple forming tables are placed in the groove, and the forming tables are stacked together. When printing the product, the product is printed on the forming table. When the device is used, the upper surface of the uppermost forming table is flush with the upper surface of the printing table 2 or slightly higher than the surface of the printing table 2.

[0026] The interior of the printing table 2 is provided with a rotatable support shaft 6, which is arranged horizontally, and a slide groove 4 is provided on the side wall of the shell 1, and the end of the support shaft 6 away from the printing table 2 extends into the slide groove 4, and a first rotating tooth 12 is fixedly connected to the support shaft 6, and a matching tooth 5 is provided on the inner wall of the shell 1, and a through hole 8 is also provided on the shell 1, and the printing table 2 can slide to the outside of the shell 1 through the through hole 8, and when the printing table 2 slides, the support shaft 6 can rotate to make the support base 3 move upward,

[0027] After the product is printed, the printing table 2 can move forward and pass through the through hole 8 to facilitate the user to remove the forming table with the product, and then gradually separate the product on the forming table. When the printing table 2 moves, the support shaft 6 can rotate, so that the support base 3 moves upward. The upward movement of the support base 3 is the height of a forming table, so that the forming table with the product can slide to the surface of the printing table 2, so that the topmost forming table can be removed and the forming table of the next layer can continue to be used.

[0028] The housing 1 is symmetrically fixed with fixing plates 9, a table 10 is fixed between the two fixing plates 9, a sliding member 11 is installed on the fixing plates 9, and the sliding member 11 can move the forming table to the table 10, and the table 10 is located on one side of the through hole 8.

[0029] The printing table 2 can slide between the two fixed plates 9, and when the printing table 2 is reset, the sliding member 11 can clamp the two sides of the forming table and slide the forming table in the direction opposite to the moving direction of the printing table 2, thereby achieving the purpose of automatically removing the forming table with the product, which is convenient for users.

[0030] The cooperation between the sliding member 11 and the forming table can be in the form of a gear rack cooperation, or can be carried out through friction.

[0031] As for how to move the topmost forming table upward, there are the following implementation methods:

[0032] A gear rack pair is formed between the first rotating tooth 12 and the matching tooth 5, so that when the printing table 2 moves, the matching tooth 5 rotates the support shaft 6;

[0033] A second rotating tooth 13 is also fixedly connected to the support shaft 6, and a third rotating tooth 14 is arranged above the second rotating tooth 13. A threaded rod 15 is fixedly connected to the lower end of the support base 3, and the threaded rod 15 passes through the third rotating tooth 14. The threaded rod 15 and the third rotating tooth 14 are coaxially arranged, and the two are threadedly matched. The lower surface of the third rotating tooth 14 is provided with an annular tooth surface, and the second rotating tooth 13 cooperates with the annular tooth surface, so that when the support shaft 6 rotates, the threaded rod 15 can drive the support base 3 to move up and down.

[0034] When the support shaft 6 rotates, the support shaft 6 can drive the second rotating tooth 13 to rotate, and the cooperation between the second rotating tooth 13 and the third rotating tooth 14 causes the third rotating tooth 14 to rotate, and the third rotating tooth 14 cooperates with the threaded rod 15, thereby causing the threaded rod 15 to move up and down, thereby achieving the purpose of supporting the base 3 to move up and down;

[0035] The threaded rod 15 has two structures as shown in the figure, thereby preventing the threaded rod 15 from rotating together with the third rotating tooth 14.

[0036] When the printing table 2 moves outward, the matching teeth 5 can cooperate with the first rotating teeth 12, thereby causing the supporting base 3 to move upward. At this time, the forming table of the next layer is located at a height that can be used to print products. In order to avoid the raised forming table from falling back to its original position when the printing table 2 is reset, the following technical solution is provided:

[0037] The first rotating tooth 12 cooperates with the upper surface of the matching tooth 5. The matching tooth 5 is rotatably mounted on the inner wall of the housing 1, and the rotation direction of the matching tooth 5 is the vertical direction. A support wheel 20 is provided below the matching tooth 5. A rotating shaft 21 is fixedly connected to the supporting wheel 20. The rotating shaft 21 and the supporting wheel 20 are arranged at different axes. When the supporting wheel 20 pushes the matching tooth 5 to the highest position, the matching tooth 5 can cooperate with the first rotating tooth 12.

[0038] That is, when the printing table 2 moves outward, the mating teeth 5 are at the highest position, and when the first rotating teeth 12 are mated with the mating teeth 5, the mating teeth 5 can move downward, and when the printing table 2 is reset, the mating teeth 5 and the first rotating teeth 12 will no longer be in contact and mated, so as to prevent the supporting base 3 from falling again;

[0039] The support shaft 6 is provided with a fixing bar 7, which is located in the slide groove 4. A first matching piece and a second matching piece are fixedly connected to the fixing bar 7, and the heights of the first matching piece and the second matching piece are different. A first arc-shaped tooth portion 22 and a second arc-shaped tooth portion 23 are fixedly connected to the rotating shaft 21, and the first arc-shaped tooth portion 22 cooperates with the first matching piece, so that when the printing table 2 moves toward the direction close to the through hole 8, and after the second rotating tooth 13 is moved by the matching tooth 5, the rotating shaft 21 can rotate to make the matching tooth 5 rotate downward, and at this time, the second arc-shaped tooth portion 23 and the second matching piece cannot contact each other. When the printing table 2 moves toward the direction away from the through hole 8, the first arc-shaped tooth portion 22 cannot cooperate with the first matching piece, and after the first arc-shaped tooth portion 22 passes over the rotating shaft 21, the second arc-shaped tooth portion 23 cooperates with the second matching piece, so that the rotating shaft 21 rotates and drives the matching tooth 5 to return to the highest position;

[0040] Furthermore, the second arc-shaped tooth portion 23 is located in front of the first arc-shaped tooth portion 22. When the printing table 2 moves outward, the second arc-shaped tooth portion 23 and the second matching piece do not contact each other and pass over the rotating shaft 21. Then, the first arc-shaped tooth portion 22 contacts and cooperates with the first matching piece, thereby causing the rotating shaft 21 to rotate. After the first matching piece and the first arc-shaped tooth portion 22 finish cooperating, the rotating shaft 21 rotates, causing the cooperating tooth 5 to move downward (the cooperating tooth 5 rotates downward under the action of gravity), and the second arc-shaped tooth portion 23 moves to a position where it can cooperate with the second matching piece. When the printing table 2 is reset, the first arc-shaped tooth portion 22 and the first matching piece do not contact each other. The first arc-shaped tooth portion 22 first passes over the rotating shaft 21, and then the second arc-shaped tooth portion 23 cooperates with the second matching piece, thereby causing the rotating shaft 21 to rotate in the opposite direction and reset, thereby lifting the cooperating tooth 5 upward and resetting it.

[0041] Regarding how to move the raised forming table with products, the following technical solutions are provided:

[0042] The sliding member 11 includes a rotating shaft 24, a connecting rod 29 is fixedly connected to the rotating shaft 24, a first rotating wheel 26 is rotatably installed at a position close to one side of the upper end of the rotating shaft 24, and a second rotating wheel 28 is rotatably installed at the upper end of the connecting rod 29. The first rotating wheel 26 and the second rotating wheel 28 are connected and driven by a belt 27. A torsion spring 25 is arranged on the outer sleeve of the rotating shaft 24. When the rotating shaft 24 is not subjected to external force, the second rotating wheel 28 tilts and tilts up and does not contact the forming table.

[0043] When the printing table 2 moves toward between the two fixed plates 9, the second rotating wheel 28 will not contact the side of the forming table. When the printing table 2 moves in the direction away from the two fixed plates 9, the second rotating wheel 28 can contact the surface of the forming table and rotate, thereby causing the forming table to slide onto the table top 10.

[0044] The fixing bar 7 is provided with an inclined toggle plate 30, the end of the inclined toggle plate 30 facing the sliding member 11 is lower, a spring 31 is installed at the lower end of the inclined toggle plate 30, a gear rack pair is formed between the side wall of the inclined toggle plate 30 and the first rotating wheel 26, and the plane where the side wall of the inclined toggle plate 30 is located passes over the side of the first rotating wheel 26;

[0045] When the printing table 2 moves between the two fixed plates 9, the lower end of the tilting plate 30 is pressed downward by the first rotating wheel 26. At this time, the spring 31 is compressed, and the tilting plate 30 cannot fluctuate the first rotating wheel 26, and the tilting plate 30 can completely pass over the first rotating wheel 26.

[0046] When the printing table 2 is reset, the higher end of the tilting plate 30 can cooperate with the side of the first rotating wheel 26. On the one hand, the tilting plate 30 can push the first rotating wheel 26 to rotate the rotating shaft 24. On the other hand, the side of the tilting plate 30 can cooperate with the side of the first rotating wheel 26 to rotate the first rotating wheel 26 and drive the second rotating wheel 28 to rotate. The rotation of the second rotating wheel 28 can also move the forming table, so that the forming table moves in the opposite direction to the printing table 2.

[0047] A first rotating wheel 26 is rotatably mounted on the upper end of the rotating shaft 24 near one side, so that after the rotating shaft 24 rotates, the first rotating wheel 26 can just cooperate with the tilting dial plate 30 .

[0048] The first matching component includes a first fixing rod 16 and a first toggle block 17 , and the second matching component includes a second fixing rod 18 and a second toggle block 19 .
