Currently, 3D printers are used to manufacture products.

[0003] However, when using existing 3D printers, some residual material will condense inside the nozzle, causing blockage. Current cleaning methods require disassembling the nozzle for unblocking, which is inconvenient. To address this issue, we propose a 3D printing nozzle cleaning and unblocking device. Utility Model Content

A material nozzle is inserted below the heating head, and a connecting mechanism is sleeved on the surface of the material nozzle. A limiting mechanism is fixed on the surface of the connecting mechanism. An assembly mechanism is threadedly connected below the connecting mechanism, and an unblocking mechanism is inserted inside the assembly mechanism.

[0007] Preferably, the connecting mechanism includes a connecting sleeve, the surface of the material nozzle is fitted with the connecting sleeve, and the side of the connecting sleeve is connected to the surface of the heating head via a connecting strap.

[0008] Preferably, the limiting mechanism includes a fixed frame, the surface of the connecting sleeve is fixedly connected to the fixed frame, and a push stud is threaded into the outer side of the fixed frame, the end of the push stud being connected to the extrusion block through a bearing.

[0009] Preferably, the inner wall dimensions of the fixed frame are adapted to the surface dimensions of the extrusion block, and the surface of the connecting sleeve is provided with through holes adapted to the extrusion block.

[0010] Preferably, the surface of the extrusion block is bonded with an anti-slip pad, and the surface of the anti-slip pad is provided with anti-slip texture.

[0011] Preferably, the assembly mechanism includes a connecting sleeve cover, the connecting sleeve cover is threaded onto the lower part of the connecting sleeve, and a magnetic ring is glued to the lower part of the connecting sleeve cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device, by fitting a connecting sleeve onto the surface of the material nozzle, allows the connecting sleeve cover to drive the cleaning head to be positioned below the material nozzle. By pushing the drive column, the drive column can drive the cleaning head to be inserted into the material nozzle, facilitating cleaning and unblocking inside the material nozzle.

An assembly mechanism 6 is threadedly connected to the lower part of the connecting mechanism 4, and an unblocking mechanism 7 is inserted inside the assembly mechanism 6.

[0027] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the connecting mechanism 4 includes a connecting sleeve 41. The surface of the material nozzle 3 is fitted with the connecting sleeve 41, and the side of the connecting sleeve 41 is connected to the surface of the heating head 2 through the connecting band 42. The connecting band 42 can facilitate the connection and limit the function of the connecting sleeve 41, and prevent the connecting sleeve 41 from being lost.

[0028] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the limiting mechanism 5 includes a fixed frame 51, the fixed frame 51 is fixedly connected to the surface of the connecting sleeve 41, and a push stud 52 is threaded into the outer side of the fixed frame 51. The end of the push stud 52 is connected to the extrusion block 53 through a bearing. By using the push stud 52 as a bearing, the extrusion block 53 can be pushed to move along the fixed frame 51 when the push stud 52 is rotated, which facilitates the function of limiting the installation of the connecting sleeve 41.

[0029] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the inner wall size of the fixed frame 51 is adapted to the surface size of the extrusion block 53. The fixed frame 51 can guide and accommodate the extrusion block 53. The surface of the connecting sleeve 41 is provided with a through hole adapted to the extrusion block 53. Through the through hole on the surface of the connecting sleeve 41, the extrusion block 53 can pass through the through hole and abut against the material nozzle 3, which facilitates the function of limiting the connecting sleeve 41.

[0030] Furthermore, refer to Figure 2 and Figure 3It can be seen that the surface of the extrusion block 53 is bonded with an anti-slip pad 54, and the surface of the anti-slip pad 54 is provided with anti-slip texture. The extrusion stability of the extrusion block 53 can be increased by the anti-slip pad 54 bonded to the surface of the extrusion block 53 and the anti-slip texture provided on its surface.

[0031] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the assembly mechanism 6 includes a connecting sleeve cover 61. The connecting sleeve cover 61 is threaded onto the lower part of the connecting sleeve 41, and a magnetic ring 62 is glued to the lower part of the connecting sleeve cover 61. The connecting sleeve cover 61 is threadedly connected to the connecting sleeve 41, which allows for quick assembly and disassembly between the connecting sleeve cover 61 and the connecting sleeve 41. The magnetic ring 62 is attached to the surface of the heating head 2, which allows the connecting sleeve 41 to be stored when not in use.

[0032] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the unblocking mechanism 7 includes a connecting stud 71. The connecting sleeve 61 is inserted with the connecting stud 71, and the lower part of the connecting stud 71 is threaded with a limit nut 72. The connecting sleeve 61 has a through hole that matches the connecting stud 71, so that the connecting stud 71 can pass through the through hole and the limit nut 72 can be threaded onto the surface of the connecting stud 71, which facilitates the disassembly and assembly of the driving column 73 and the cleaning head 74. The driving column 73 is fixedly connected to the upper part of the connecting stud 71, and the cleaning head 74 is fixedly connected to the upper part of the driving column 73. The driving column 73 can drive the cleaning head 74 to be inserted into the material nozzle 3, which is convenient for unblocking and cleaning the material nozzle 3.

[0033] Working principle: When this utility model is in use, during the cleaning process of the material nozzle 3, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4By pulling the connecting sleeve 41, the connecting sleeve cover 61 can cause the magnetic ring 62 to separate from the heating head 2. Then, the connecting sleeve 41 is fitted onto the surface of the material nozzle 3, and rotating the push stud 52 pushes the extrusion block 53 and anti-slip pad 54 through the connecting sleeve 41 to contact the surface of the material nozzle 3, facilitating the limiting function of the connecting sleeve 41. At this time, pushing the drive column 73 causes it to drive the cleaning head 74 to insert into the material nozzle 3, facilitating the unblocking and cleaning of the material nozzle 3. The connecting sleeve cover 61 and the magnetic ring 62 can collect the waste from the unclogging and cleaning. When the connecting sleeve 41 is not in use, the connecting sleeve cover 61 can drive the magnetic ring 62 to attract the heating head 2, limiting and storing the connecting sleeve 41. When the cleaning head 74 needs to be replaced, by rotating the connecting sleeve cover 61, the connecting sleeve cover 61 can be separated from the connecting sleeve 41, and the limiting nut 72 can be separated from the connecting stud 71, so that the driving stud 73 and the cleaning head 74 can be taken out from the connecting sleeve cover 61 for replacement.
