Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to an anti-clogging 3D printer nozzle. Background Art

[0002] A 3D printer, also known as a three-dimensional printer, is a machine using a cumulative manufacturing technology, that is, a rapid prototyping technology. It is based on a digital model file and uses special wax materials, powdered metal or plastic and other adhesive materials to create three-dimensional objects by printing layers of adhesive materials.

[0003] At present, three-dimensional printers are used to manufacture products, and the technology of constructing objects by printing layer by layer. The principle of 3D printers is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. The 3D printer nozzle is one of the components of the 3D printer.

[0004] However, in existing 3D printers, glue will remain inside the glue head after each printing is completed. After the glue cools down, it will solidify at the glue outlet of the glue head, causing the glue head to be blocked and affecting the next use.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the above background technology, the prior art has the problem that after each printing is completed, glue will remain inside the glue head. After the glue cools down, it will solidify inside the glue head, causing the glue head to be blocked, affecting the next use.

[0007] The utility model discloses an anti-clogging 3D printer, comprising a mounting bracket and a rubber head, wherein the upper surface of the mounting bracket is fixedly connected to a micro motor, the output shaft of the micro motor is fixedly connected to a threaded rod 1, the outer surface of the mounting bracket is provided with a sliding groove, the inner wall of the sliding groove is slidably connected to a sliding block, the outer surface of the threaded rod 1 is threadedly connected to the inner wall of the sliding block, the right side of the sliding block is fixedly connected to the mounting block, the inner wall of the mounting block is rotatably connected to a rotating bracket, the outer surface of the rotating bracket is fixedly connected to a semicircular block, the outer surface of the semicircular block is slidably connected to the inner wall of the mounting block, and the inner wall of the rotating bracket is fixedly connected to a blocking rod.

[0008] Furthermore, a material barrel is fixedly connected to the inner wall of the mounting frame, and a booster pump is fixedly installed on the upper surface of the material barrel.

[0009] Furthermore, the upper surface of the barrel is fixedly connected to a feed pipe, and the outer surface of the barrel is fixedly connected to a connecting piece 1.

[0010] Furthermore, the outer surface of the rubber head is fixedly connected to a second connector, and the inner wall of the second connector is rotatably connected to two threaded rods arranged at equal distances.

[0015] 1. The utility model is provided with components such as a micro motor, a threaded rod, a sliding block, a mounting block, a rotating frame, and a baffle rod. When the printer is used up, the micro motor drives the threaded rod to rotate, and the threaded rod drives the sliding block to descend inside the sliding groove, and drives the mounting block to descend through the sliding block. When it descends to the lowest point of the sliding groove, the rotating frame is manually rotated to drive the semicircular block to rotate and drive the baffle rod to move. At this time, the baffle rod is located below the glue outlet, and then the micro motor reverses the threaded rod to drive the sliding block to rise, and then the baffle rod is raised to push the glue inside the glue head upward until the baffle rod completely enters the glue head.
