Problems solved by technology

[0007] The purpose of the present invention is to provide a 3D printing device with multi-angle corner correction function in order to solve the above problems, so as to solve the gradient heating of raw materials in the preheating process and / or hot melting process in the prior art , so as to ensure that the raw material will not be subjected to high-temperature heat-assisted process for a long time before spraying, which will cause mechanical property variation, and at the same time, it can effectively prevent the material output efficiency from being too low due to the heat-assisted temperature being too low and the viscosity of the sprayed material being too high before spraying. , nozzle clogging and poor molding effect; it is further used to solve the problems of the ejected material in the prior art when it leaves the interior of the jet nozzle, and the obvious direction-changing scattering occurs, which cannot effectively correct the injection trajectory, resulting in stripes on the finished product Seriously, it increases the difficulty and cost of post-processing of finished products, and affects the work efficiency of 3D printing equipment

Embodiment 1

[0040] see figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , this embodiment provides a 3D printing device with a multi-angle corner correction function, including an equipment casing 1 and a spray device 3, the bottom of the spray device 3 is fixedly connected with a discharge nozzle 4, and the outer side of the discharge nozzle 4 is rotated and sleeved with a heat Auxiliary device 6, a material pipe 2 is fixedly connected between the injection device 3 and the equipment shell 1, an electromagnet ring 5 is sleeved on the outer side of the thermal auxiliary device 6, and the electromagnet ring 5 is fixedly connected to the bottom of the injection device 3, and one side of the thermal auxiliary device 6 is An air pump 7 is fixedly connected, a plurality of vertical pipes 9 are arranged at the bottom of the air pump 7, a threaded pipe 11 is threadedly connected to one side of the plurality of vertical pipes 9, and a ventilation groove 22 is opened on the outside of ...

Embodiment 2

[0044] On the basis of Example 1, please refer again to figure 1 , figure 2 , image 3 and Figure 4 , in the 3D printing device in this embodiment, a plurality of vertical pipes 9 are installed on the outside of the air outlet of the air pump 7 through the annular pipe 8, and the vertical pipes 9 are equally spaced on the annular pipe 8, figure 2 , image 3 A schematic diagram of four standpipes 9 is shown in FIG. 1 , and the distance between two adjacent standpipes 9 is a quarter of the circumference of the annular pipe 8 . Each vertical pipe 9 is correspondingly installed with a threaded pipe 11 , and each threaded pipe 11 is correspondingly installed with a correction running-in piece 10 to the bottom of the outer side of the discharge nozzle 4 . Therefore, a plurality of threaded pipes 11 arranged at equal distances make a plurality of correction running-in pieces 10 . A circular pipe is formed, and the path of the raw material sprayed by the discharge nozzle 4 is c...

Embodiment 3

[0048] On the basis of Embodiment 1-2, in order to avoid 3D printing stripes caused by mechanical vibration, this embodiment is further provided with an inclination sensor, which is arranged inside the discharge nozzle 4 to measure the horizontal angle change of the discharge nozzle 4 . The inclination sensor is connected with the controller, and the controller adjusts the opening of the electromagnetic switch according to the detection result of the inclination sensor, so as to adjust the inclination angle of the correction running-in sheet 10 .

[0049] Specifically, when the discharge nozzle 4 of the 3D printing device is displaced or angularly deflected due to mechanical vibration, the inclination sensor feeds back the horizontal angle change of the discharge nozzle 4 to the controller, which specifically includes spatial angle information such as horizontal angle and vertical angle. According to the horizontal angle change measured by the inclination sensor, the controller...

Abstract

The invention provides a 3D printing device and method with a multi-angle corner correction function, and relates to the field of 3D printing. The 3D printing device with the function of correcting the corners of the multi-angle jetting material includes an equipment casing and a jetting device, the bottom of the jetting device is fixedly connected with a discharging nozzle, and a thermal auxiliary device is rotatably sleeved on the outer side of the discharging nozzle. The 3D printing device with multi-angle injection material corner correction function corrects the raw material corners ejected by the discharge nozzle, controls and corrects the inclination angle of the running-in sheet according to the time when the air pump is on Adjust the position of the correction running-in sheet, so that the correction running-in sheet can correct the corners of the raw material ejected by the discharge nozzle from multiple angles, reduce the streak on the surface of the finished product processed by the injection device, and reduce the printing of the injection device and the discharge nozzle. cost input.
