Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, specifically a wax feeding mechanism for a 3D printer. Background Technology

[0002] The 3D printer wax feeding mechanism is a system used to store and transport synthetic wax filament material to the 3D printer nozzle, ensuring a continuous supply of synthetic wax filament material during the printing process. By precisely controlling the amount of synthetic wax filament material transported, the stability of the printing process and the printing quality are guaranteed.

[0003] In existing technologies, since the synthetic wax filament material in 3D printers is wound up, a support frame is usually used to support and store the roll during material storage and feeding. The rotation of the roll is used to transport the material. However, in actual use, since the support frame is usually exposed on the outside, dust will adhere to the outside of the synthetic wax filament material stored on the outside, causing the 3D printed product to be affected by dust and impurities. Therefore, it is necessary to improve the wax storage and feeding mechanism of a 3D printer to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a wax feeding mechanism for a 3D printer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 3D printer wax storage and feeding mechanism, including a base plate, wherein a dust removal feeding mechanism and a material storage mechanism are provided on the top of the base plate.

[0006] Preferably, the dust removal feeding mechanism includes a fixed upright plate, which is fixedly installed on the top of the base plate. A conveying roller is rotatably installed inside the fixed upright plate, and a gear is fixedly installed on the back of the conveying roller. A dual-head motor is fixedly installed on the front of the fixed upright plate, and a guide tube is fixedly installed on the left side of the fixed upright plate. A fixed block and a high-pressure air pump are fixedly installed on the top of the base plate, and an air supply pipe is fixedly installed on the right side of the high-pressure air pump. A sealing ring is fixedly installed on the front of the fixed block, and a rotating cover is rotatably installed on the front of the rotating cover. An air outlet pipe is fixedly installed on the front of the rotating cover, and a hollow transmission roller is fixedly installed on the outside of the rotating cover. A transmission belt is driven externally on the hollow transmission roller, and a solid transmission roller is driven at the end of the transmission belt away from the hollow transmission roller, which facilitates surface dust removal of the fed synthetic wax filament material by the dust removal feeding mechanism.

[0007] Preferably, the back of the drive shaft of the dual-head motor on the back is fixedly installed to the front of the bottom conveyor roller, and the front of the drive shaft of the dual-head motor on the front is fixedly installed to the back of the solid drive roller, so that the conveyor roller and the rotating cover can rotate synchronously.

[0008] Preferably, the fixed block has an internal ventilation groove, and the end of the air supply pipe away from the high-pressure air pump is fixedly installed on the left side of the fixed block, which facilitates the delivery of high-pressure air under normal conditions.

[0009] Preferably, there are two gears, and the two gears mesh with each other, which facilitates the two conveying rollers to rotate in opposite directions.

[0010] Preferably, the storage mechanism includes a fixed frame, which is fixedly installed on the top of the base plate. A fixed roller is fixedly installed inside the fixed frame, and a storage roller is rotatably installed outside the fixed roller. A bolt is threaded inside the fixed roller, and a baffle is provided outside the bolt to facilitate the storage of the storage roller through the storage mechanism.

[0011] Preferably, a hole is provided at the corresponding position of the baffle and the bolt, and the bolt is slidably installed inside the hole provided inside the baffle, so as to facilitate the fixing of the baffle.

[0012] Compared with the prior art, this utility model provides a 3D printer wax storage and feeding mechanism, which has the following beneficial effects:

[0013] 1. The wax feeding mechanism of this 3D printer, through the dust removal feeding mechanism, utilizes the mutual transmission between two gears to enable two conveying rollers to rotate in opposite directions. Under the guidance of the guide tube, the synthetic wax filament material is fed and conveyed. Simultaneously, the transmission of the hollow drive roller, drive belt and solid drive roller enables the rotating cover to drive the air outlet pipe to rotate synchronously with the conveying roller. Then, the set high-pressure air pump and air delivery pipe deliver high-pressure air to spray dust off the surface of the synthetic wax filament material. Before the synthetic wax filament material is printed, the surface dust is removed by synchronous rotation air spraying, avoiding the impact of dust and impurities on the printed product.

[0014] 2. The 3D printer's wax feeding mechanism, through its storage mechanism, uses bolts and baffles to limit the storage roller during use, allowing it to rotate outside the fixed roller, thus realizing the function of storing synthetic wax filament material for 3D printing.

[0024] Example 1:

[0025] Please see Figure 1-4 This utility model provides a technical solution: a wax storage and feeding mechanism for a 3D printer, including a base plate 1, and a dust removal and feeding mechanism 2 and a storage mechanism 3 are provided on the top of the base plate 1.

[0026] Furthermore, the dust removal feeding mechanism 2 includes a fixed vertical plate 21, which is fixedly installed on the top of the base plate 1. A conveying roller 22 is rotatably mounted inside the fixed vertical plate 21. A gear 23 is fixedly installed on the back of the conveying roller 22. A dual-head motor 24 is fixedly installed on the front of the fixed vertical plate 21. A guide tube 214 is fixedly installed on the left side of the fixed vertical plate 21. A fixed vertical block 25 and a high-pressure air pump 26 are fixedly installed on the top of the base plate 1. An air supply pipe 27 is fixedly installed on the right side of the high-pressure air pump 26. A sealing ring 28 is fixedly installed on the front of the fixed block 25. A rotating cover 29 is rotatably installed on the front of the fixed block 25. An air outlet pipe 210 is fixedly installed on the front of the rotating cover 29. A hollow transmission roller 211 is fixedly installed on the outside of the rotating cover 29. A transmission belt 212 is driven on the outside of the hollow transmission roller 211. A solid transmission roller 213 is driven on the end of the transmission belt 212 away from the hollow transmission roller 211, so as to facilitate the surface dust removal of the fed synthetic wax filament material by the dust removal feeding mechanism 2.

[0027] Furthermore, the back of the drive shaft of the dual-head motor 24 is fixedly installed on the front of the bottom conveyor roller 22, and the front of the drive shaft of the dual-head motor 24 is fixedly installed on the back of the solid drive roller 213, so that the conveyor roller 22 and the rotating cover 29 can rotate synchronously.

[0028] Furthermore, the fixed block 25 has an internal ventilation groove, and the end of the air supply pipe 27 away from the high-pressure air pump 26 is fixedly installed on the left side of the fixed block 25, which facilitates the delivery of high-pressure air under normal conditions.

[0029] Furthermore, there are two gears 23, and the two gears 23 mesh with each other, which facilitates the two conveying rollers 22 to rotate in opposite directions.

[0030] Example 2:

[0031] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the material storage mechanism 3 includes a fixed frame 31, which is fixedly installed on the top of the base plate 1. A fixed roller 32 is fixedly installed inside the fixed frame 31, and a material storage roller 33 is rotatably installed outside the fixed roller 32. A bolt 34 is threaded inside the fixed roller 32, and a baffle 35 is provided outside the bolt 34 to facilitate the storage of the material storage roller 33 through the material storage mechanism 3.

[0033] In actual operation, when this device is used, after the storage roller 33 containing the synthetic wax filament material is placed over the outside of the fixed roller 32, the baffle 35 is placed over the back of the fixed roller 32 and fixed with bolts 34, thus limiting the storage roller 33. The synthetic wax filament material is then pulled through the inside of the conveying roller 22 and into the guide tube 214, protruding from the end of the guide tube 214 near the fixed block 25. This drives the dual-head motor 24, causing the drive shaft of the dual-head motor 24 to start rotating. The transmission of gear 23 causes the conveying roller 22 to start rotating, conveying the synthetic wax filament material. At the same time, the high-pressure air pump 26 is driven, so that the air pipe 27 delivers high-pressure air to the inside of the fixed block 25. The gas will be sprayed out from the inside of the air outlet pipe 210. When the air outlet pipe 210 sprays air, it will be driven to rotate by the rotating cover 29 through the transmission of the hollow transmission roller 211, the transmission belt 212 and the solid transmission roller 213. The air outlet pipe 210 starts to rotate and spray air at the same time, spraying off the dust on the surface of the conveyed synthetic wax filament material.
