Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, and in particular to a transfer device for 3D printing. Background Art

[0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis and uses adhesive materials such as powdered metal or plastic to construct objects by printing layer by layer.

[0003] In the 3D printing process, after the spraying process is completed, the molding chamber containing the blank needs to be transferred to the barbecue oven for baking. After baking, the blank is formed. In this process, a transfer device is required to transport the molding chamber to the platform of the transfer device, and then the transfer device is placed in the baking oven for baking.

[0004] When the blank is baked and formed, the powdered metal or plastic on the blank will fall off on the inner wall of the forming bin, and the fallen powdered metal or plastic needs to be cleaned. In the prior art, the blank needs to be taken out of the forming bin before cleaning. However, there is a defect in the cleaning in the prior art. During the removal of the blank, the powdered metal or plastic will be directly taken out and diffused in the air, resulting in low cleaning efficiency. In addition, the scattered powdered metal and plastic will affect the health of the cleaning personnel. In addition, since the bottom wall is at the deepest point, it is not convenient to clean.

[0005] Therefore, it is necessary to propose a transfer device for 3D printing, which can not only prevent powdered metal or plastic from spreading in the air, but also facilitate cleaning and improve cleaning efficiency, and ensure the health of cleaning personnel. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and to propose a transfer device for 3D printing, which can prevent powdered metal or plastic from spreading in the air, facilitate cleaning, improve cleaning efficiency, and ensure the health of cleaning personnel.

[0007] The purpose of the utility model is achieved through the following technical solutions: a transfer device for 3D printing, comprising a frame with a hollow interior and a molding bin, the molding bin having an opening on the upper side and a bottom wall that slides up and down, the frame being provided with a placement seat for placing the molding bin, a top rod that slides through the frame, the top rod that slides up and down through the placement seat, and a top block that is used to make the bottom wall slide up and down is provided on the upper end of the top rod.

[0008] Support parts are arranged on both sides of the upper end of the placing seat, and rollers are arranged on one side adjacent to the two support parts.

[0009] The placing seat is provided with a limiting member for limiting the movement of the forming bin.

[0010] The limiting member is rotatably arranged on the placing seat.

[0011] A plurality of pulleys are arranged on the lower side of the frame.

[0012] The frame is provided with a handle for easy pushing.

[0013] A worm gear is rotatably arranged inside the frame body, and the push rod is threadedly rotatably passed through the worm gear. Slide rails are arranged on both sides of the frame body, and a locking piece for limiting the rotation of the push rod is arranged on the push rod, and the locking piece is slidably connected to the slide rail.

[0014] A turning handle is rotatably arranged on the frame body, a worm is meshed with the worm wheel, and the turning handle is connected to the worm.

[0015] It also includes a transparent cover which is detachably mounted on the molding bin, and at least one cover opening is formed on the transparent cover.

[0016] The cover opening is provided with a shielding cover cloth which can be turned over.

[0017] The beneficial effect of the utility model is that by setting the frame, the sliding setting of the bottom wall of the molding bin, the push rod, etc., when it is necessary to clean the powdered metal or plastic on the bottom wall of the molding bin, the bottom wall is lifted up from the molding bin opening, and the staff can clean the powdered metal or plastic on the bottom wall of the molding bin. After cleaning, the push rod is lowered, and the bottom wall is recovered to the original position under the action of gravity. Since the green blank is cleaned first and then taken out, it can not only prevent the powdered metal or plastic from spreading in the air, but also facilitate cleaning and improve cleaning efficiency, and can ensure the health of the cleaning personnel.
