Automatic cooling device for spray head of 3D printer

Abstract

The invention discloses an automatic cooling device for a spray head of a 3D printer. The outer surface of the spray head is wound with a cooling tube in the vertical direction; the cooling tube is connected with a water circulating device; water flows in a circulating mode for radiating heat of the spray head; a temperature sensor is arranged on a supporting table; a controller is arranged on the water circulating device; the controller is connected with the temperature sensor; temperature induction is performed on the spray head of the 3D printer through the temperature sensor; when the temperature of the spray head is too high, the temperature sensor is used for transmitting information to the controller; and the controller automatically starts the water circulating device for radiating heat of the spray head. The cooling device is simple in structure, is relatively low in cost, is good in effect, and does not affect printing operation.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, in particular to an automatic cooling device for nozzles of 3D printers. Background technique [0002] As one of the core components of the 3D printer, the nozzle of the 3D printer determines the quality of the molding to a large extent. The smoothness of the filament flowing out of the extrusion nozzle and the temperature of the filament directly affect the accuracy of the 3D printing. However, if the temperature of the nozzle is too high or other parts are dissolved and burned, a cooling device is required to control the temperature of the nozzle within a certain range. However, at the present stage, during the printing process of 3D printers, relying on people to identify the temperature and then turn on the cooling device has brought inconvenience to the printing work, so it is of great significance to have an automatic cooling device for the printer nozzle.

However, if the temperature of the nozzle is too high or cause other parts to dissolve and burn, a cooling device is required to control the temperature of the nozzle within a certain range

However, in the printing process of 3D printers at this stage, relying on people to identify the temperature and then turn on the cooling device brings inconvenience to the printing work, so it is of great significance to have an automatic cooling device for the printer nozzle

[0003] Chinese patent CN106541572A discloses a 3D printer nozzle cooling device, including: a fixed table, a cooling water pipe, and a water circulation device. The cooling water pipe is wound on the outer surface of the nozzle to cool the 3D printer nozzle. The cooling device can realize the cooling of the nozzle. However, the device cannot be automatically turned on according to the temperature of the nozzle, which brings inconvenience to the 3D printing work
