A 4D printing nozzle temperature control device

Abstract

This utility model discloses a 4D printing nozzle temperature control device, relating to the field of 4D printing nozzle technology. The device includes: a nozzle tube with multiple openings on its outer side; and a heating mechanism located inside the nozzle tube. The heating mechanism includes a temperature regulating plate, a fixed cylinder, and an electromagnetic induction coil. The temperature regulating plate is fixedly installed inside the openings and is inclined. The fixed cylinder is fixedly installed on the outer side of the nozzle tube, and the electromagnetic induction coil is fixedly installed on the inner side of the fixed cylinder. By controlling the activation of the electromagnetic induction coil, the temperature regulating plate heats up under electromagnetic induction, heating the hydrogel inside the nozzle tube. This prevents the hydrogel from solidifying due to excessive cooling inside the nozzle tube, facilitating extrusion, reducing damage to the device, and extending its service life. An externally connected thermal resistor temperature measuring device is used to detect the temperature of the hydrogel inside the nozzle tube, facilitating temperature control and improving printing quality.
