Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to an adjustable multi-nozzle device for 3D printing. Background Technology

[0002] 3D printing, also known as additive manufacturing, is a technology that manufactures solid parts by adding materials layer by layer based on three-dimensional CAD data. The history of 3D printing technology is one of continuous progress and expansion. From early rapid prototyping technology to its widespread application today, 3D printing technology is used in design and manufacturing fields such as jewelry design, footwear design and manufacturing, industrial design, architectural design, engineering design and construction, and automotive design and manufacturing, as well as in medical fields such as aerospace and dentistry.

[0003] In the 3D printing process, thermoplastic materials are heated and extruded, and three-dimensional objects are built by stacking the materials layer by layer. However, when 3D printing products of different colors, it is necessary to change the plastic color and clean the nozzle before printing can be done again, which wastes a lot of time and reduces printing efficiency. To address the above problems, the inventors have proposed an adjustable multi-nozzle device for 3D printing to solve the above problems. Utility Model Content

[0004] To address the issue of needing to change the plastic color and clean the nozzle before printing again when 3D printing products of different colors, the purpose of this invention is to provide an adjustable multi-nozzle device for 3D printing.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: an adjustable multi-nozzle device for 3D printing, including a base plate, a printing table fixedly mounted on the top surface of the base plate, a movable frame slidably mounted on the top surface of the base plate, a movable plate slidably mounted on one side of the movable frame, a mounting plate slidably mounted on one side of the movable plate, a rotating disk rotatably mounted inside the mounting plate, a fixed frame fixedly mounted on the top surface of the base plate, an extrusion mechanism mounted on the top surface of the fixed frame, and three sets of extrusion mechanisms, each set having an extrusion tube fixedly mounted on one side, all three sets of extrusion tubes fixedly inserted into the fixed frame, all three sets of extrusion tubes having a flexible tube fixedly mounted at the bottom end, all three sets of flexible tubes having a nozzle fixedly mounted at the bottom end, and all three sets of nozzles fixedly penetrating inside the rotating disk; an ear plate fixedly mounted on the top surface of the mounting plate, a motor mounted inside the ear plate, a gear fixedly mounted on the output end of the motor, and a toothed part fixedly mounted on the outer surface of the rotating disk. The ring, which meshes with a gear, has a fixed ring fixedly fitted on the outer surface of the rotating disk. The fixed ring is rotatably mounted in the mounting plate, which has a limiting groove. The fixed ring is rotatably mounted in the limiting groove. First, the material is placed in the extrusion mechanism. The material in the extrusion mechanism is heated by turning on the heating mechanism. Then, the extrusion mechanism is turned on, so that the material can be conveyed into the extrusion tube, then into the hose, and sprayed out from the nozzle. By turning on the cooling fan, air is conveyed into the fixed frame, thereby cooling the raw material during the printing process. The heat and exhaust gas generated during the printing process are discharged from the through groove and conveyed into the first exhaust pipe. Then, the exhaust gas passes through the activated carbon plate, thereby purifying the exhaust gas for discharge. The activated carbon plate is bolted into the limiting frame, making it easy to remove the limiting frame from the support seat. At the same time, the insertion rod is disengaged from the support seat, making it easy to replace the activated carbon plate.

[0006] By turning on the motor, the gears rotate, meshing with the gear rings to drive the rotating disk, which in turn rotates the three sets of nozzles. The nozzles are then adjusted according to the desired color, bringing them closer to one side of the moving plate. This allows for quick nozzle adjustment when changing to different ink colors, saving time and improving printing efficiency. (In subsequent adjustments, turning on the motor reverses the gears, causing the three sets of nozzles to rotate in reverse, thus preventing the three sets of hoses from tangling.)

[0007] Preferably, a first exhaust pipe is fixedly provided on both sides of the fixed frame, a support seat is fixedly sleeved on the outer surface of the first exhaust pipe, a limiting frame is slidably provided on the top surface of the support seat, an activated carbon plate is installed in the limiting frame, a second exhaust pipe is fixedly provided in the support seat, the activated carbon plate is attached between the first exhaust pipe and the second exhaust pipe, an insertion rod is fixedly provided on the bottom surface of the limiting frame, the insertion rod is slidably inserted in the support seat, a through groove is opened in the fixed frame, and the first exhaust pipe communicates with the through groove.

[0008] Preferably, a cooling fan is installed inside the fixed frame, and a dustproof net is installed inside the fixed frame on one side of the cooling fan.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. By rotating the rotating disk, three sets of nozzles are driven to rotate. The nozzles are then adjusted according to the desired color, so that the required nozzles are close to one side of the moving plate. This allows for quick nozzle adjustment when changing different raw material colors, thus saving a lot of time and improving printing efficiency.

[0011] 2. The heat and exhaust gas generated during the printing process are discharged from the through-slot and transported to the first exhaust pipe, where they pass through the activated carbon plate to purify the exhaust gas before it is discharged. Attached Figure Description

[0019] 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.

[0020] Example: Figure 1-5As shown, this utility model provides an adjustable multi-nozzle device for 3D printing, including a base plate 1, a printing table 12 fixedly mounted on the top surface of the base plate 1, a movable frame 13 slidably mounted on the top surface of the base plate 1, a movable plate 14 slidably mounted on one side of the movable frame 13, a mounting plate 23 slidably mounted on one side of the movable plate 14, a rotating disk 24 rotatably mounted inside the mounting plate 23, a fixed frame 11 fixedly mounted on the top surface of the base plate 1, and an extrusion mechanism 2 mounted on the top surface of the fixed frame 11. The number of extrusion mechanisms 2 is three sets, and an extrusion tube 21 is fixedly mounted on one side of each of the three sets of extrusion mechanisms 2. All three sets of extrusion tubes 21 are fixedly inserted into... Within the fixed frame 11, the bottom ends of the three sets of extrusion tubes 21 are all fixedly equipped with hoses 22, and the bottom ends of the three sets of hoses 22 are all fixedly equipped with nozzles 221. The three sets of nozzles 221 are all fixedly inserted into the rotating disk 24. The top surface of the mounting plate 23 is fixedly equipped with an ear plate 27, and a motor 28 is installed inside the ear plate 27. A gear 29 is fixedly equipped at the output end of the motor 28. A gear ring 25 is fixedly fitted on the outer surface of the rotating disk 24, and the gear ring 25 meshes with the gear 29. A fixing ring 26 is fixedly fitted on the outer surface of the rotating disk 24, and the fixing ring 26 is rotatably mounted in the mounting plate 23. A limit groove 231 is provided in the mounting plate 23. The fixed ring 26 is rotatably mounted in the limiting groove 231. Electric slide rail mechanisms are installed in the base plate 1, the movable frame 13, and the movable plate 14, thereby driving the nozzle 221 to move. A heating mechanism is provided inside the extrusion mechanism 2. By activating the heating mechanism, the material inside the extrusion mechanism 2 is heated, and then the extrusion mechanism 2 is activated, allowing the material to be conveyed into the extrusion tube 21, then into the hose 22, and finally ejected from the nozzle 221. (The extrusion mechanism 2 is set in three groups, and the material inside each group is a different color. During use, the corresponding extruder group is activated.) (Structure 2) By turning on the motor 28, the gear 29 rotates. The gear 29 meshes with the gear ring 25, which in turn rotates the rotating disk 24 and drives the three sets of nozzles 221 to rotate. Then, the nozzles 221 are adjusted according to one of the required colors, so that the required nozzles 221 are close to the side of the moving plate 14. When changing different raw material colors, the nozzles 221 can be quickly adjusted, thus saving a lot of time and improving printing efficiency. (In subsequent adjustments, the motor 28 is turned on, the gear 29 is reversed, and the three sets of nozzles 221 are reversed, thus avoiding the three sets of hoses 22 from getting tangled.)

[0021] Both sides of the fixed frame 11 are fixedly provided with first exhaust pipes 3. The outer surface of the first exhaust pipe 3 is fixedly fitted with a bearing seat 31. The top surface of the bearing seat 31 is slidably provided with a limiting frame 33. An activated carbon plate 34 is installed in the limiting frame 33. A second exhaust pipe 32 is fixedly provided in the bearing seat 31. The activated carbon plate 34 is attached between the first exhaust pipe 3 and the second exhaust pipe 32. The bottom surface of the limiting frame 33 is fixedly provided with an insertion rod 35. The insertion rod 35 is slidably inserted in the bearing seat 31. A through groove 111 is opened in the fixed frame 11. The first exhaust pipe 3 and the through groove 111 are interconnected.

[0022] By adopting the above technical solution, the heat and exhaust gas generated during the printing process are discharged from the through groove 111 and transported to the first exhaust pipe 3, and then pass through the activated carbon plate 34, thereby purifying the exhaust gas for discharge. The activated carbon plate 34 is bolted into the limiting frame 33, which makes it easy to remove the limiting frame 33 from the support seat 31. At the same time, the insertion rod 35 is disengaged from the support seat 31, which makes it easy to replace the activated carbon plate 34.

[0023] A cooling fan 16 is installed inside the fixed frame 11, and a dustproof net 15 is installed inside the fixed frame 11 on one side of the cooling fan 16.

[0024] By adopting the above technical solution, by turning on the cooling fan 16, air is delivered into the fixed frame 11, thereby cooling the raw material during the printing process.

[0025] Working principle: First, the material is placed in the extrusion mechanism 2. The heating mechanism is turned on to heat the material in the extrusion mechanism 2. Then, the extrusion mechanism 2 is turned on, so that the material can be conveyed into the extrusion tube 21, then into the hose 22, and sprayed out from the nozzle 221. By turning on the cooling fan 16, air is conveyed into the fixed frame 11, thereby cooling the raw material during the printing process. The heat and exhaust gas generated during the printing process are discharged from the through groove 111 and conveyed into the first exhaust pipe 3. Then, the exhaust gas passes through the activated carbon plate 34, which can purify the exhaust gas for discharge. The activated carbon plate 34 is bolted into the limiting frame 33, which makes it easy to remove the limiting frame 33 from the support seat 31. At the same time, the insertion rod 35 is disengaged from the support seat 31, which makes it easy to replace the activated carbon plate 34.

[0026] By turning on the motor 28, the gear 29 rotates, and the gear 29 meshes with the gear ring 25 to drive the rotating disk 24 to rotate, which in turn drives the three sets of nozzles 221 to rotate. The nozzles 221 are then adjusted according to the desired color, so that the desired nozzles 221 are close to the side of the moving plate 14. This allows for quick adjustment of the nozzles 221 when changing different raw material colors, thus saving a lot of time and improving printing efficiency. (In subsequent adjustments, turning on the motor 28 reverses the gear 29, which in turn reverses the three sets of nozzles 221, thus preventing the three sets of hoses 22 from getting tangled.)

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
