Description

Technical Field

[0001] This utility model relates to the field of 3D printer technology, specifically to a vibration powder cleaning device for 3D printers. Background Technology

[0002] The surface of the powder feeding shaft inside the powder feeding unit of a 3D printer is usually provided with grooves. Powder falls into the grooves of the powder feeding shaft through the powder inlet channel, and then the powder feeding shaft transports the powder to the powder outlet channel by rotating. However, due to static electricity, powder is easy to stick to the grooves on the surface of the powder feeding shaft, which prevents the powder feeding shaft from transporting the powder to the powder outlet channel, thus causing blockage of the powder inlet channel. It is often necessary to manually disassemble the powder feeding unit and remove the powder feeding shaft for powder cleaning before it can work normally. The cleaning operation is cumbersome and inconvenient, and it also affects work efficiency. Utility Model Content

The powder feeding base 1 has a powder inlet channel 11, a powder feeding chamber 12, and a powder outlet channel 13 arranged sequentially in a vertically connected manner. A powder feeding shaft 2 is disposed within the powder feeding chamber 12. Multiple grooves 21 are provided on the surface of the powder feeding shaft 2 along the circumferential direction. A driving component 3, which is a motor, is connected to one end of the powder feeding shaft 2 along its axial direction. The driving component 3 is used to drive the powder feeding shaft 2 to rotate. The other end of the powder feeding shaft 2 is coaxially connected to... The driving component, the powder vibration mechanism 4, vibrates back and forth along the axial direction and transmits the vibration to the powder feeding shaft 2 to remove the powder adhering to the groove 21 on the surface of the powder feeding shaft 2. This allows the powder feeding shaft 2 to smoothly transport the powder to the powder discharge channel 13, thereby preventing the powder from accumulating at the powder inlet channel 11 and causing blockage. The powder cleaning operation is achieved by ultrasonic vibration. Compared with the traditional method of manually disassembling the powder feeding shaft 2 to manually clean the powder, this powder cleaning method is simpler and faster, and significantly improves work efficiency.

[0026] In this embodiment, the driving component powder vibration mechanism 4 includes a fixed cable outlet 41, a rotating cable outlet 42, and a transducer 43 sequentially assembled along the axial direction. The fixed cable outlet 41 is fixedly installed on the device to provide an inlet for the cable. The rotating cable outlet 42 and the transducer 43 are rotatably configured. The end of the transducer 43 away from the fixed cable outlet 41 is fixedly connected to the powder feeding shaft 2. A conductive slip ring 44 electrically connected to the transducer 43 is installed inside the rotating cable outlet 42. The rotating cable outlet 42 protects and guides the cable of the rotating part. The conductive slip ring 44 realizes uninterrupted power / signal transmission in the rotating state. The transducer 43 is used to convert high-frequency electrical energy into ultrasonic vibration.

[0027] In this embodiment, the powder inlet channel 11 is offset on one side of the top of the powder feeding chamber 12, and the width of the powder inlet channel 11 corresponds to the width of the groove 21. The powder outlet channel 13 is offset on the other side of the bottom of the powder feeding chamber 12, and the width of the powder outlet channel 13 is greater than the width of the groove 21, so as to ensure that the powder falling process is smoother and more orderly and controllable.

[0028] In this embodiment, a powder feeding chamber 5 is installed on the top of the powder feeding base 1. The powder feeding chamber 5 is connected to the powder feeding channel 11. The cross-section of the powder feeding chamber 5 gradually decreases from top to bottom, thereby ensuring that the powder feeding process is smoother and more orderly and controllable.

[0029] In this embodiment, the length direction of the groove 21 is parallel to the axial direction of the powder feeding shaft 2, so that the groove 21 and the powder feeding channel 11 are precisely connected and matched to achieve precise powder delivery. The diameter of the powder feeding chamber 12 corresponds to the diameter of the powder feeding shaft 2, so that the amount of powder stored in the groove 21 corresponds to the amount of powder fed, thereby ensuring precise, controllable, uniform and stable powder feeding.
