Problems solved by technology

[0002] The walking structure of the print head of the 3D printer in the prior art widely uses the synchronous belt and the slider guide rail as the structure for transmitting power, and connects the synchronous belt with the printer head to realize the smooth movement of the working parts. The synchronous belt of the prior art is made of plastic material The closed circular ring structure made is easy to deform due to the plastic material during use, especially under the action of friction and tensile tension during the working process, it is easy to elongate and produce plastic deformation, and it is inconvenient to adjust after deformation. The working parts have poor moving stability and large speed fluctuations, which affect the accuracy of the transmission, thereby affecting the accuracy of the processed workpiece, and even cause unqualified products. After the deformation is out of tolerance, the synchronous belt is scrapped. The structure of the guide rail is also relatively complicated, and it is prone to failure, which increases the cost of use and maintenance

Abstract

The invention discloses a printing head walking structure of a 3D printer. The printing head walking structure of the 3D printer comprises a guide rail, a synchronous belt, a driving belt wheel and a driven belt wheel. The two ends of the synchronous belt are connected with the driving belt wheel and the driven belt wheel respectively. The synchronous belt is connected with a printing head fixing base. The lower portion of the fixing base is connected with a sliding block. The sliding block is connected with the guide rail. The fixing base is provided with a printing supply feeding motor. A left connecting column and a right connecting column are arranged on the fixing base and located on the left side and the right side of the printing head fixing base respectively. The middle of the synchronous belt is broken, so that a left connecting end and a right connecting end are formed. The left connecting end is connected with the left connecting column. The right connecting end is connected with the right connecting column. The printing head walking structure of the 3D printer is simple; the tension degree of the synchronous belt can be adjusted conveniently, the adjustment precision is high, the service life of the synchronously belt is prolonged, and both use cost and maintenance cost are reduced; the position of the synchronous belt is fixed reliably, looseness is unlikely to occur after the tension degree is adjusted to be proper, the movement smoothness and movement reliability of movable components are kept, and the requirement for precise control over the movement of the components can be met.
