Description

Technical Field

[0001] This utility model relates to the field of printer equipment, specifically to a nozzle module for a 3D printer. Background Technology

[0002] 3D printing technology is a technique for creating solid objects by layering materials, also known as additive manufacturing (AM). The basic principle of 3D printing is to create a 3D model, divide the designed model into several layers, and then print each layer until a complete object is formed. Wax-spray 3D printers are a type of additive manufacturing equipment. They use blue wax as the model material and white wax as the support material. High-temperature heated wax is sprayed onto the printing platform, and the model is built by stacking layers. Due to the advantages of high precision and smooth surface of wax-spray 3D printed models, wax-spray 3D printers are widely used in the jewelry, aerospace, and engine manufacturing industries. The printing materials used in wax-spray 3D printers are white wax and blue wax. The wax is contained in a container, which is then inserted into an ink supply assembly. The blue wax in the container flows into the ink supply assembly, is heated at high temperature, and flows into the nozzle. The nozzle sprays the wax layer by layer onto the printing panel to build the 3D model.

[0003] The multi-nozzle installation structure of existing 3D printers is relatively complex. Each nozzle of the nozzle must fall precisely within a designated area. Since 3D printers generally have multiple nozzles, each nozzle has multiple nozzles. In traditional 3D printers, nozzle installation is difficult and the installation position adjustment accuracy is not high, resulting in low 3D printing accuracy and inconvenience during maintenance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 and Figure 3 A nozzle module for a 3D printer is mounted on a nozzle frame 1 and can slide horizontally along the nozzle frame 1. The nozzle module includes a base 2 and three nozzles 3. Three mounting ports (not shown in the figure) are provided on the bottom plate 21 of the base 2. The three mounting ports are arranged in a triangular shape. The three nozzles 3 are respectively disposed in the mounting ports. A mounting frame 4 is provided between the nozzles 3 and the mounting ports on the bottom plate 21 of the base 2. A rotation adjustment device is provided at one end of the mounting frame 4 for adjusting the angle of the nozzles 3, so that the three nozzles 3 remain parallel in the horizontal direction.

[0025] like Figure 4 , Figure 5 and Figure 6As shown, the rotary adjustment device is an adjusting screw 5. One end of the adjusting screw 5 has an adjusting handle 51, and the other end has a connecting block 52. The connecting block 52 is connected to the slot 44 on the mounting frame 4 at the lower end of the nozzle 3. When the adjusting handle 51 of the adjusting screw 5 is rotated, the adjusting screw 5 moves back and forth relative to the adjusting seat 53 on the bottom plate 21 of the base 2. The connecting block 52 of the adjusting screw 5 drives one end of the nozzle 3 to rotate relative to the connecting seat 54 on the other end of the nozzle, thereby adjusting the angle of the nozzle. A displacement adjusting screw 6 is provided on the bottom plate 21 of the base 2. One end of the displacement adjusting screw 6 has an adjusting knob 61, and the other end has a connecting cap 62. The connecting cap 62 is connected to the limiting groove 45 on the mounting frame 4. When the adjusting knob 61 of the adjusting screw 6 is rotated forward and backward, the adjusting screw 6 moves back and forth relative to the nut seat 63 on the bottom plate 21 of the base 2. The connecting cap 62 of the adjusting screw 6 drives the nozzle to move horizontally, thereby adjusting the horizontal distance between the nozzles.

[0026] like Figure 6 As shown, a mounting frame 4 is provided between the nozzle 3 and the mounting port on the base plate 21 of the base 2, facilitating the installation of the nozzle 3 onto the base plate 21. The upper frame 43 of the mounting frame 4 is positioned above the mounting port on the base plate 21, and the lower frame 41 of the mounting frame 4 falls into the mounting port on the base plate 21. The length of the upper frame 43 is greater than the length of the lower frame 41. Steps 42 extend inward and towards each other on both sides of the inner frame of the mounting frame 4. The steps 42 abut against the edge of the nozzle module of the nozzle 3 to fix the nozzle 3. The nozzle 3 is installed on the mounting port on the base plate 21 of the base 2 via the mounting frame 4, making installation convenient and quick.

[0027] like Figure 1 and Figure 2 As shown, the base 2 also includes a mounting plate 22 and two side plates 23. The two side plates 23 are respectively connected to the two ends of the front of the mounting plate 22. The back of the mounting plate 22 is slidably connected to the nozzle frame 1. The lower ends of the mounting plate 22 and the two side plates 23 are connected to the edge of the upper surface of the base plate 21, forming a semi-enclosed structure. The nozzle 3 is installed inside the semi-enclosed structure. An L-shaped connecting plate 24 is provided between the two side plates 23 and the mounting plate 22. A locking screw 25 is provided on the L-shaped connecting plate 24 for fastening the side plates 23 and the mounting plate 22. On the side plate 23 of the base 2, near the end of the base plate 21, an opening 231 is provided. The opening 231 is opposite to the adjustment knob 61 of the displacement adjustment screw 6 for easy operation of the displacement adjustment screw 6.

[0028] The beneficial technical effects of this embodiment are as follows: the nozzles are installed on the three mounting ports on the base plate via the mounting frame, making installation convenient and quick. Each nozzle is equipped with a rotation adjustment device and a displacement adjustment screw, which can precisely adjust the nozzle position. In addition, the two side plates of the base are detachable, facilitating maintenance and operation.
