Cleaning device of spray head for 3D printer

Abstract

The invention relates to the technical field of printer cleaning, in particular to a cleaning device of a spray head for a 3D printer. The cleaning device comprises a box body. A through hole is formed in the top end face of the box body. The inner side wall of the through hole is in sliding connection with a sliding block. A first spring is arranged on the inner side of the sliding block. A steelneedle is arranged on the inner side of the sliding block and is in sliding connection with the sliding block. One end of the first spring is fixedly connected with the sliding block, and the other end of the first spring is fixedly connected with the steel needle. The bottom end of the left end face of the sliding block is fixedly connected with a sliding frame. The inner side of the sliding frame is in sliding connection with a sliding shaft. The left end face of the sliding shaft is fixedly connected with an eccentric wheel. The inner side of the left end face of the box body is fixedly connected with a first motor. In the cleaning device, through the arranged first motor and eccentric wheel, the eccentric wheel is driven by the first motor to rotate to control up-and-down motion of the steel needle, a spray head is dredged, clearing work is facilitated, and the spray head is cleared faster and more thoroughly through high-frequency clearing.

[0002] 3D printer, also known as 3D printer, is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. With the development and progress of society, the emergence of 3D printers provides great convenience to our lives, but some printers are in In the process of use, there will inevitably be some small problems. For example, the nozzle will be blocked after a long time of use. The traditional cleaning method is to directly pull out the blockage by man-made mechanical tools, and then use a steel needle to clean the inside. The cleaning method will cause a certain degree of damage to the 3D printer, which will increase the maintenance frequency of the 3D printer to a certain extent, and some 3D printers will not be cleaned thoroughly through manual cleaning when cleaning the blockage inside the discharge port. And it is very inconvenient to clean up, therefore, the demand for a nozzle cleaning device for 3D printers is increasing day by day

[0003] At present, the cleaning method of some 3D printer nozzles is to directly use iron pliers to clamp and pull out the exposed part, and then manually dredge it through a steel needle. This method will cause a certain degree of damage to the 3D printer and shorten its service life. First of all, it is inconvenient to clean the internal blockages. On the other hand, cleaning is prone to incomplete cleaning of internal blockages, which increases the frequency of cleaning. Therefore, a nozzle cleaning device for 3D printers is proposed to solve the above problems.
