Description

Technical Field

[0001] This utility model belongs to the field of 3D printing technology, and more specifically, it relates to a 3D printing material overflow liquid collection and mixing device. Background Technology

[0002] When a product is processed using a 3D printer, the liquid material inside the 3D printer is ejected through the 3D printing process, thus forming the product. During product processing, excess liquid material will flow out, forming overflow liquid. In order to ensure the recycling and reuse of the overflow liquid, a collection and mixing device is required. The overflow liquid is collected by the collection and mixing device and then reused.

[0003] According to CN201721625828.1, this utility model discloses a 3D printer, including a heating device, an inner shell with a receiving cavity, an outer shell fitted over the inner shell, and a heat insulation component covering the receiving cavity and used to insulate the heat inside the receiving cavity; the inner shell has an exhaust port communicating with the receiving cavity, which is used to connect with the outside. This utility model's technical solution heats the ambient temperature inside the receiving cavity by setting up a heating device, and simultaneously, by fitting an outer shell over the inner shell with a heat insulation component, the heat inside the receiving cavity is not easily dissipated. Furthermore, the exhaust port on the inner shell communicating with the receiving cavity ensures that the air pressure inside the receiving cavity is consistent with the external air pressure, thereby guaranteeing a constant ambient temperature inside the receiving cavity.

[0004] Based on the above, existing mixing and collection devices typically use rectangular collection buckets to collect overflow liquid. However, when the overflow liquid in the bucket accumulates to a certain amount and needs to be cleaned, the staff must first remove the collection bucket from inside the 3D printer. Since the collection bucket must be moved during the cleaning process, the shaking during the movement can easily cause the liquid inside the bucket to overflow, which not only wastes materials but may also bring additional cleaning burden. Utility Model Content

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model employs a box-mounting mechanism, which allows the mixing box to be installed inside the printing body via positioning holes and positioning pins. This ensures that the mixing box is stably installed inside the printing body to collect overflow liquid, while also facilitating the removal of the mixing box from the printing body by the operator. The mixing device inside the mixing box mixes the overflow liquid.

[0015] This invention employs a protective housing mechanism. When the mixing housing is stably inside the printing body, the protective cover is open, allowing overflow liquid to flow into the mixing housing for collection and mixing. When the mixing housing is removed from the printing body, the protective cover is closed, thus confining the overflow liquid inside the mixing housing. This prevents overflow liquid from flowing out of the mixing housing when workers move it, making it convenient for workers to collect and clean the overflow liquid using the mixing device. Cleaning the overflow liquid inside the mixing housing is as simple as pulling the protective cover, facilitating the use of the mixing device. Attached Figure Description
