The invention relates to the technical field of fast designing and forming machines, in particular to a novel precise 3D printer. The novel precise 3D printer comprises a supporting mechanism, a feeding mechanism, a first-level movement mechanism, a second-level movement mechanism and a spray head mechanism. The supporting mechanism is used for supporting the whole 3D printer and a formed product. The feeding mechanism is used for storing and providing wire filler needed by the 3D printer for printing the product. The first-level movement mechanism and the second-level movement mechanism are used for driving a spray head to carry out printing movement. The spray head mechanism is used for melting and extruding the wire filler and can cool printing materials at the same time. According to the novel precise 3D printer, it can be selected that only the first-level movement mechanism works and can be used for printing products with small sizes and low precise requirements, only the second-level movement mechanism works and can be used for printing products with small printing sizes and high precision or fine structures on the surfaces of products, and when the first-level movement mechanism and the second-level movement mechanism work in cooperation, the first-level movement mechanism is used for achieving rough positioning, and the second-level movement mechanism is used for carrying out precise printing work.

The invention discloses an intelligent nozzle of a 3D (Three-Dimensional) printer. The intelligent nozzle of the 3D printer comprises a fixed bracket, a cover plate, a concave bracket, a heat conduction block and a material guide pipe, wherein the cover plate is mounted at the top of the fixed bracket; the concave bracket is mounted at the bottom of the fixed bracket; the heat conduction block is mounted at the bottom of the concave bracket; an extrusion head is arranged at the front end of the material guide pipe; the material guide pipe is vertically arranged in the fixed bracket; the extrusion head is exposed out of the bottom of the heat conduction block; the intelligent nozzle of the 3D printer also comprises at least one heating part and at least one temperature sensing part; the heating part and the temperature sensing part are mounted in the heat conduction block. The extrusion head of the intelligent nozzle comprises the heating part and the temperature sensing part and is capable of accurately controlling the thread extrusion temperature, guaranteeing the smooth thread extrusion and automatically cleaning the nozzle; all circuit lines are fixed in the nozzle, so that the problem that the circuit lines are abraded, broken and cut out in the process of moving the extrusion head is avoided.

The invention provides a multi-station automatic-adjustment wheel type gel spinning machine. The multi-station automatic-adjustment wheel type gel spinning machine comprises a spinning box, a power mechanism and a control system, wherein the power system supplies power to the spinning box; two same stations are arranged in the spinning box; the control system selects the station needing to work by controlling connection and disconnection of an electromagnetic clutch; and the control system is connected with the power mechanism and the heating mechanism to realize self-adaptive adjustment of the rotating speeds of a driving rubber roll and a driven rubber roll with the gelation temperature. The multi-station automatic-adjustment wheel type gel spinning machine provided by the invention has the advantages that by controlling the self-adaptive adjustment of the rotating speeds of the rubber rolls and the gelation temperature, spun yarns can reach the nano level; and by adjustment to the gap between the driving rubber roll and the driven rubber roll, uniform silk production and difficult silk breaking are realized; and the two stations can work simultaneously, so that the working efficiency is effectively improved.
