Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Embodiment:

[0025] Please refer to Figure 1 - Figure 4 A fence for 3D printing in the embodiment comprises a main fence 1, the main fence 1 is provided with an adjusting mechanism, the adjusting mechanism is provided with a sub-fence 6, the sub-fence 6 is provided with an observation mechanism, the adjusting mechanism comprises an adjusting assembly 2, the adjusting assembly 2 comprises a support 21, the support 21 is fixedly installed on the inner wall of the main fence 1, the inner wall of the support 21 is fixedly installed with a first motor 23, the rotating shaft end of the first motor 23 is fixedly installed with a gear 24, the gear 24 is engagedly connected with a rack 22, the sub-fence 6 is fixedly installed on the end of the rack 22;

[0026] The observation mechanism includes an observation component 3, which includes a second motor 33. The second motor 33 is fixedly installed on the side of the partition 6. The shaft end of the second motor 33 passes through the partition 6 and is provided with a first conveyor wheel 39. The inner wall of the partition 6 is rotatably connected to a second conveyor wheel 34. The first conveyor wheel 39 and the second conveyor wheel 34 are meshed with the same conveyor belt 36. The partition 6 is provided with an observation window 32, and a limit rod 37 is fixedly installed on the conveyor belt 36.

[0027] The bracket 21 is L-shaped, the first motor 23 is horizontally positioned, and the gear 24 is horizontally positioned.

[0028] The main fence 1 is provided with limiting grooves 4. The cross-sectional shape of the limiting grooves 4 is T-shaped. The limiting grooves 4 are set horizontally, and there are no fewer than four limiting grooves 4.

[0029] A sliding rod 5 is fixedly installed on the inner wall of the partition 6. The sliding rod 5 is horizontally set and has a T-shaped cross-section. The sliding rod 5 slides within the limiting groove 4.

[0030] The inner wall of the partition 6 is provided with a horizontal bar 38, which is horizontally set. A frame 35 is slidably set on the horizontal bar 38. The frame 35 is vertically set and is in the shape of a strip frame. The limiting rod 37 slides inside the frame 35.

[0031] A mounting plate 310 is fixedly installed at the bottom of the frame 35. The mounting plate 310 is a square rod and is set vertically.

[0032] A sponge 31 is fixedly installed on the mounting plate 310, and the sponge 31 slides on the observation window 32.

[0033] When the size of the fence needs to be adjusted, the first motor 23 is started. The first motor 23 drives the gear 24 to rotate. The gear 24 meshes with the racks 22 on both sides, which will drive the two side fences 6 to move through the racks 22. Under the limiting action of the limiting slide groove 4 and the slide rod 5, the two side fences 6 will move in opposite linear motion, which, together with the main fence 1, achieves the purpose of adjusting the size of the fence, which is beneficial for the 3D printer to print items of different sizes.

[0034] With the observation window 32 provided, staff can observe the printing process of the 3D printer. When impurities adhere to the inner wall of the observation window 32 and obstruct the view, the second motor 33 is activated. The second motor 33 drives the first transmission wheel 39 to rotate. When the first transmission wheel 39 rotates, it works in conjunction with the second transmission wheel 34 to drive the conveyor belt 36. When the conveyor belt 36 is in motion, it drives the limit rod 37 to move. When the limit rod 37 moves, it drives the frame 35 to move back and forth in a straight line along the surface of the crossbar 38. When the frame 35 moves back and forth in a straight line, it drives the sponge 31 on the surface of the mounting plate 310 to move back and forth in a straight line. When the sponge 31 moves back and forth in a straight line, it wipes the observation window 32 back and forth, thus making it convenient for staff to observe the printing process through the observation window 32.
