Description

Technical Field

[0001] The utility model relates to the technical field of 3D printer cleaning, and particularly relates to a nozzle cleaning device for a 3D printer. Background Art

[0002] As a core component in the printing process, the working state of the 3D printing nozzle directly affects the printing quality, precision and efficiency. However, during actual use, the nozzle often needs to print different materials or colors, which may cause different types of printing materials to remain on the outside of the nozzle. These residues not only affect the color purity and printing precision of subsequent printing, but may also cause nozzle blockage, thereby affecting the normal operation of the printer.

[0003] In view of this, a nozzle cleaning device for a 3D printer is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a device aiming at the deficiencies of the prior art. The purpose is that the device can thoroughly clean various residues on the outside of the nozzle, avoid damaging the nozzle and materials at the same time, improve the printing quality and efficiency, and reduce the maintenance cost.

[0005] To achieve the above technical purposes, the technical solution adopted by the utility model is as follows:

[0006] A nozzle cleaning device for a 3D printer includes a motor drive device, a fixed mounting seat, a gear, a rack and a cleaning brush; the fixed mounting seat is in the structure of a C-shaped groove, and side guide grooves with the left side lower and the right side higher are respectively arranged on the inner sides of the front and rear walls of the fixed mounting seat; the gear is fitted in the C-shaped groove through tooth fitting and cooperates with the rack, the rack is installed in the C-shaped groove through the side guide grooves, the cleaning brush is installed at the right end of the rack, and the motor drive device drives the gear to rotate, driving the left and right movement of the rack, thereby driving the left and right movement of the cleaning brush to realize the cleaning of the nozzle.

[0007] As a further optimization of the solution, a control module is further included, which realizes the start and stop functions in a wired or wireless manner.

[0008] As a further optimization of the solution, an identification module is further included, which automatically detects the type and degree of residues on the nozzle surface through an image recognition algorithm, thereby adjusting the material, hardness, cleaning strength and cleaning path of the brush head to realize more accurate cleaning.

[0009] As a further optimization of the solution, the cleaning brush is a plastic brush and is fixedly connected to the right end of the rack.

[0010] As a further optimization of the solution, the cleaning brush includes a fast-rotating brush handle and a brush head; while the cleaning brush moves left and right along with the rack, the fast-rotating brush handle drives the brush head to perform a rotating motion, realizing the function of fast cleaning.

[0011] As a further optimization of the solution, the cleaning brush includes a rotating brush handle and a multi-functional brush head; the multi-functional brush head has a multi-faceted structure, and different bristles are arranged on each face. During the cleaning process, according to different working states, by rotating the rotating brush handle, the bristles on different faces can achieve different cleaning functions.

[0012] The beneficial effects produced by adopting the above technical solutions are as follows:

[0013] 1. Reducing manual intervention and operation risks: Traditional cleaning methods mostly rely on manual operations, while the spray brush cleaning device realizes automated or semi-automated cleaning, reducing manual intervention, lowering the operation difficulty and risks, and improving the safety and reliability of the cleaning process.

[0014] 2. Improving printing quality and efficiency: Residual materials may cause nozzle blockage, deteriorated printing quality, or even printing failure. By regularly or as needed cleaning the nozzle efficiently with the brush cleaning device, it can ensure that the nozzle is always in good condition, thus improving printing quality and efficiency and reducing production delays and cost waste caused by nozzle problems.

[0015] 3. Prolonging the service life of the nozzle: The long-term accumulation of residual materials will corrode and wear the nozzle, shortening its service life. The brush cleaning device reduces the erosion of the residue on the nozzle through regular cleaning, helping to prolong the service life of the nozzle and reducing the replacement frequency and cost.
