3D printer head

Abstract

The invention discloses a 3D printer head. The 3D printer head comprises a body, a connecting pipe is fixedly connected to the outer surface of the upper end of the body, a fixing ring is movably connected to the position, close to the upper end, of the outer circular surface of the connecting pipe, a connecting rod is fixedly connected to the outer surface of the upper end of the fixing ring, anda buffer ring is fixedly connected to the upper end of the connecting rod. A first spring is fixedly connected to the inner surface of the buffer ring, a clamping plate is fixedly connected to one section of the first spring, a fixed pulley is fixedly connected to the inner surface of the clamping plate, an elastic rope is slidably connected to the outer circular surface of the fixed pulley, anda fixing block is slidably connected to the inner surface of a placing groove. According to the 3D printer head, a material conveying pipe of a printer can be rapidly fixed, printing failure caused byseparation of the material conveying pipe in the printing process is avoided, the use stability is improved, and the product production quality is enhanced; and meanwhile, when other pigments need tobe replaced, the printer head does not need to be replaced, and therefore the use range of the printer head is widened.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printer head. Background technique [0002] At present, with the advancement of science and technology, 3D printing technology is becoming more and more mature. 3D printer, also known as 3D printer (3DP), is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is a digital model file for Based on the use of bondable materials such as special waxes, powdered metals or plastics, three-dimensional objects are created by printing layers of bonded materials. [0003] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: 1. When the existing 3D printer is used, the feeding tube at the upper end of the printer head will move along with the movement of the printer head. Shaking, after a period of use, the stability of the connection between the gu...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: 1. When the existing 3D printer is used, the feeding tube at the upper end of the printer head will move along with the movement of the printer head. Shaking, after a period of use, the stability of the connection between the guide feeding tube and the printer will decrease, causing the feeding tube at the upper end of the printer head to be in danger of detaching from the printer head at any time, resulting in printing failure and reducing production. quality, which reduces the stability of the equipment; 2. When the printer head is working, the feeding pipe on the printer head increases with the number of movement of the machine head, causing the connection between the feeding pipe and the connecting pipe to be worn, reducing and plastic pipe The service life of the machine increases, and the cost of use is increased. At the same time, when other pigments need to be replaced for printing, a new machine head needs to be replaced to print. head, thus increasing the cost, if the original head is used when replacing the paint, it is easy to cause color unevenness and color difference
