3D printing head with pressure sensing high-temperature-resisting pulp

Abstract

The invention provides a 3D printing head with pressure sensing high-temperature-resisting pulp. The 3D printing head is arranged on a three-shaft linkage platform and comprises a storage module and a discharging module. The storage module is located in a heat isolation bin module. The heat isolation bin module is a cuboid bin, and each of an upper bin plate and a lower bin plate of the heat isolation bin module is provided with a through hole. The lower end of the storage module is connected with the discharging module through the through hole of the lower bin plate, wherein the discharging module is located below the heat isolation bin module. The spraying direction of the storage module points at the printing plane of the three-shaft linkage platform. The upper end of the storage module is connected with the lower end of an extrusion push rod module through the through hole of the upper bin plate. The upper end of the extrusion push rod module is connected with a linear displacement mechanism module doing the vertical movement through a pressure sensing module. According to the 3D printing head, the pressure is detected according to the extrusion force of the push rod on a pressure sensor, and the problem of damage on equipment due to continuous extrusion in a plugging state is effectively solved; and meanwhile, the discharging module and the storage module are simple in structure and easy to detach, and the problem that the 3D printing head is difficult to maintain and clean is effectively solved.

Description

technical field [0001] The invention relates to a 3D printing head with pressure-sensitive and high-temperature-resistant slurry, which belongs to the technical field of printing. Background technique [0002] 3D printing technology is a new type of layer-by-layer superposition technology, which is now mainly used in industrial-grade metals, ceramics, polymers, etc., and is still small-batch and personalized production and processing. Printing 3D models by injection extrusion is one of the current methods of 3D printing models. However, at present, this printing method cannot detect the clogging problem in the printing process in time, resulting in damage to the equipment caused by continuous extrusion in the clogging state. At the same time, there are also the problems of narrow application range of printing materials and difficulty in cleaning and maintaining equipment. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present ...
