Detailed Description
The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts are within the scope of the present disclosure.
As shown in fig. 1 to 2, a 3D printer head cooling device comprises a nozzle 1 and a heat dissipation shell 2, wherein a retaining ring 12 is arranged on the nozzle 1, and the heat dissipation shell 2 is clamped on the retaining ring 12; a heat-conducting cylinder 3 is arranged in the heat-radiating shell 2, the heat-conducting cylinder 3 is attached to the outer wall of the nozzle 1, a spiral downward heat-radiating fin 31 is arranged on the outer wall of the heat-conducting cylinder 3, an air inlet 21 is arranged at the top of the heat-radiating shell 2, an air outlet 22 is arranged at the bottom of the heat-radiating shell, an air duct 221 is arranged at the air outlet 22, and an opening of the air duct 221 is arranged upwards; the side wall of the heat dissipation shell 2 is connected with a plurality of auxiliary vent pipes 23, the auxiliary vent pipes 23 are connected with vent pipes 24 arranged on the outer wall of the heat dissipation shell 2, and the vent pipes 24 are connected with the air inlet 21.
The nozzle 1 is provided with a gradually contracting head 11, the outer wall of the head 11 is provided with a temperature detector 13, and the temperature detector 13 detects the temperature of the head 11 and transmits the detected data.
The upper end of the nozzle 1 is provided with threads and is connected with a nut 14 by the threads, and the nut 14 is pressed on the top end of the heat dissipation shell 2 to limit the separation of the heat dissipation shell.
The number of the auxiliary breather pipes 23 is three.
The three auxiliary vent pipes 23 have different distances therebetween, and the distance between the upper two auxiliary vent pipes is smaller than the distance between the lower two auxiliary vent pipes.
The heat conducting cylinder 3 is divided into three parts, a plurality of annular holes are formed in the heat conducting cylinder 3 from top to bottom along the axial direction, and elastic ropes are arranged in the holes; the rope is in tension, pressing the three parts together.
The heat conducting cylinder 3 of the device is sleeved on the nozzle 1, and the heat of the nozzle 1 is conducted to the heat conducting cylinder 3 and then to the radiating fins 31 by utilizing the characteristic of good heat conduction of metal, so that the radiating treatment is carried out. The heat sink 31 is disposed spirally along the outer wall of the heat conducting tube 3.
The temperature detector 13 of the device detects the temperature of the head 11, and if the temperature exceeds a target value, the temperature needs to be reduced. The reason why the temperature detector is provided in the head 11 is that the temperature detector is closest to the ejection hole and can most represent the actual temperature of the material to be subjected to the printing operation.
In the heat dissipation shell 2, air with lower temperature is introduced to act on the heat dissipation fins 31, so that heat dissipation is accelerated. Simultaneously, because nozzle 1 length is longer, consequently this device sets up three auxiliary ventilation pipe 23 and assists jet-propelled to guarantee that the air temperature that lets in is enough low, can accelerate the heat dissipation.
After the air passes through the heat sink, the temperature rises, and in order to avoid affecting the printing operation, the air duct 221 with an upward opening is provided in the present apparatus. This is arranged so that the hot air is directed toward the bottom of the nozzle 1, thereby not adversely affecting the print job at the front end.
If the temperature of the head 11 detected by the temperature detector 13 meets the requirements after heat dissipation, the temperature of the print head 1 is not lowered.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
