Description

Technical Field

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

[0002] With the gradual development and popularization of 3D printers, objects are constructed by additive manufacturing layer-by-layer printing based on digital model files, using adhesive materials such as PLA or ABS. Using 3D printers to print models does not require traditional cutting machines and molds, and can even complete some workpieces that cannot be processed by traditional processing. Under the control of a computer, a three-dimensional entity can be directly formed according to the three-dimensional model of the workpiece. However, when operating a 3D printer in life, it is often due to model defects or improper use that unsatisfactory products are printed and eventually discarded. Each failed print also causes a lot of waste of materials. If the waste consumables can be recycled, it will greatly reduce costs and waste. For this reason, some devices that can recycle 3D printing materials have appeared in the prior art. For example, China's public patent CN112248445A records a 3D printing material recycling device, which involves the field of material recycling technology, including a bracket, a recasting device, a crushing device, a heating device, a cooling device and a take-up device. The crushing device is placed on the top of the bracket, and the recasting device is placed on the bracket. The heating device is sleeved on the surface of the recasting device and fixed on the bottom of the crushing device. The cooling device is placed below the output end of the recasting device. The wire-receiving device is placed beside the output end of the recasting device. The recasting device includes a recasting motor, a spiral blade and a recasting tube. The recasting motor is fixed on a baffle near the center of the bracket. The output end of the recasting motor is fixedly connected with the spiral blade. The recasting tube is sleeved on the outside of the spiral blade. When in use, the waste is crushed by the crushing device, and then the waste is melted by the heating device. The extruded solution is cooled into a linear shape by the cooling device, and then the wire-receiving device is used to receive it in the wire-receiving reel, thereby realizing the recycling and reuse of the waste and reducing the pollution to the environment.

[0003] However, in the prior art, the heating pipe is an integral pipe sleeved outside the recast pipe, and the cooling device is also a cooling pipe spirally wound on the outer wall of the recast pipe. Such an overall assembly structure makes it difficult to disassemble and assemble the device, resulting in inconvenient upgrades and inspections of equipment components in the later stage. In addition, the current consumables for 3D printing are generally PLA or ABS, and the existing consumables recycling devices are not effectively compatible with these two materials, so their application is also subject to certain restrictions.
