Description

Technical Field

[0001] This application relates to the technical field of 3D printing equipment, especially 3D printing equipment that can quickly cure plastics into high-temperature and high-pressure resistant shells. Background Art

[0002] 3D printing technology is a rapid prototyping technology that uses digital model files as a basis and applies special wax materials, powdered metals, plastics, and other bondable materials to manufacture three-dimensional objects by printing layer upon layer of materials. Fused deposition modeling is one of the main 3D printing technologies. This technology melts a hot-melt filament and extrudes it from a nozzle, depositing it on a forming platform or the previously cured material of the previous layer to finally generate a physical object.

[0003] In the prior art, due to the different shapes of different objects after the hot-melt wire is ejected, the thicknesses of different parts are also different. Therefore, the cooling and solidification times required are also different, which may cause some parts with a relatively thick thickness to not be cooled in the first place. Once the physical object is touched prematurely at this part, it is easy to leave defects and affect the appearance.

[0004] The prior art can only extend the cooling time and take it out after all parts are completely cooled. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of this application is a 3D printing equipment that can quickly cure plastics into high-temperature and high-pressure resistant shells, which is used to solve the technical problems in the background art.

[0006] The above purpose of this application is achieved through the following technical solutions: A 3D printing equipment that can quickly cure plastics into high-temperature and high-pressure resistant shells, including a nozzle for spraying. A plurality of base brackets are arranged outside the nozzle, and a top cover is fixedly arranged at the upper end of the base brackets. One side of the nozzle is connected to a transportation pipeline, and the other end of the transportation pipeline is connected to a storage tank fixedly connected to the top cover. The bottom of the nozzle is provided with a base platform fixedly connected to the middle of the base brackets. A curing plate for placing a physical object is arranged at the upper end of the base platform. A translation device for driving the curing plate to move is arranged on the base platform. An ultraviolet light assembly for irradiating the printed product is arranged outside the nozzle.

[0007] By adopting the above technical solutions, the raw materials in the storage tank are transported to the nozzle through the transportation pipeline and sprayed onto the curing plate. At this time, the ultraviolet lamp assembly outside the nozzle will continuously irradiate the plastic material to improve the curing speed. At the same time, the setting of the translation device can improve the printing path and printing efficiency.

[0008] Further, the ultraviolet light assembly includes connecting rods disposed on both sides of the nozzle. Slide rods are installed on the connecting rods. The ends of the slide rods are fixedly connected to mounting plates, and ultraviolet light strips are fixedly provided on the mounting plates.

[0009] Further, a sliding frame is slidably disposed on the slide rod. The sliding frame is slidably connected to the connecting rod. A micro motor is fixedly connected to the sliding frame. A driving gear is fixedly provided at the output end of the micro motor. A driven gear bar meshing with the driving gear is fixedly provided on the slide rod.

[0010] By adopting the above technical solution, the ultraviolet light strip is installed on the mounting plate and is disposed outside the ultraviolet light strip. During the printing process, the printed article is continuously illuminated to improve curing. And according to the light required by the actual situation, through the setting of the micro motor, the driving gear can be driven to rotate, so as to cooperate with the gear bar to move the sliding frame on the slide rod, thereby adjusting the distance between the ultraviolet light strip and the nozzle.

[0011] Further, a driving ring is fixedly provided between the connecting rods. A rotating groove for the driving ring to rotate is formed on the outer side of the nozzle. A rotating motor is fixedly provided on the driving ring. A rotating gear is fixedly provided at the output end of the rotating motor. A linkage gear meshing with the rotating gear is fixedly provided on the nozzle.

[0012] By adopting the above technical solution, the driving ring fixedly provided between the connecting rods is matched with the rotating groove formed on the outer side of the nozzle, so that the driving ring can rotate on the nozzle. The rotating motor fixed on the driving ring meshes with the linkage gear fixed on the nozzle through the rotating gear at its output end. When the rotating motor works, the rotating gear rotates accordingly, and the entire driving ring is driven to rotate on the nozzle through gear transmission. Since the ultraviolet light assembly is connected to the driving ring, when the driving ring rotates, the entire ultraviolet light assembly will also rotate accordingly. This rotating function enables the ultraviolet light strip to irradiate the printed part more evenly, reduce the shadow area, thereby improving the curing quality and the consistency of the printed part.

[0013] Further, reflecting plates connected to the mounting plate are disposed on the upper and lower sides of the ultraviolet light strip. Rotating blocks are fixedly connected to both ends of the mounting plate. Rotating shafts are fixedly connected to the reflecting plates. The rotating shafts are rotatably connected to the rotating blocks at both ends. Linkage motors are fixedly provided on the rotating blocks. The output ends of the linkage motors are fixedly connected to the rotating shafts.

[0014] By adopting the above technical solutions, the reflector plates added on the upper and lower sides of the ultraviolet lamp strip are driven by a linkage motor with independent control, enabling multi-angle adjustment. The surface of the reflector plate adopts an electroplated nickel substrate plus a silica dielectric film reflective layer, which can be applicable to the elliptical focused light spot for line-scan curing and the oblique light field formed by deflecting the single-side reflector plate, effectively solving the curing problem at the bottom of the overhanging structure. In terms of optimizing the curing process, the reflector plate adjustment mechanism realizes the dynamic adjustment of the curing energy density, significantly improving the curing depth and the interlayer bonding strength. At the same time, the asymmetric light spot mode reduces the temperature gradient and residual stress.

[0015] Further, a damping piece fixedly connected to the reflector plate is arranged on the rotating shaft.

[0016] Further, a sliding frame is arranged at the upper end of the nozzle. A sliding shell is slidably arranged on the sliding frame. The sliding shell is fixedly connected to the nozzle. One end of the sliding frame is rotatably connected to a driving shaft, and the other end is rotatably connected to a driven shaft. A moving belt is sleeved on the driving shaft and the driven shaft. One side of the sliding frame is fixedly connected to the moving belt. A sliding motor is fixedly connected to the bottom of the sliding frame, and the output end of the sliding motor is connected to the driving shaft.

[0017] By adopting the above technical solutions, the driving of the sliding motor drives the driving shaft to rotate, causing the moving belt to rotate, thereby driving the sliding frame to move back and forth, making the printing path more precise, thus greatly improving the accuracy and surface quality of the printed parts. At the same time, the design of the sliding frame enables the nozzle to move freely within a larger range, easily adapting to printed parts of different sizes and shapes. This flexibility not only expands the application scenarios of the equipment but also improves the versatility of the equipment, enabling it to meet more diverse printing requirements. In addition, the driving of the sliding motor makes the movement of the nozzle faster and more stable, effectively shortening the printing cycle and improving the printing efficiency.

[0018] Further, an adjusting motor is arranged at the upper end of the sliding frame. The output end of the adjusting motor is fixedly connected to the sliding frame. A pushing cylinder is arranged at the upper end of the adjusting motor. The output end of the pushing cylinder is fixedly connected to the adjusting motor, and the pushing cylinder is fixedly connected to the top cover.

[0019] By adopting the above technical solutions, the setting of the pushing cylinder is used to drive the nozzle to move linearly up and down. At the same time, with the setting of the adjusting motor, the sliding frame can be rotated to drive multi-angle printing.

[0020] Further, the translation device includes a groove opened at the bottom of the curing plate. A sliding protrusion that slides relative to the groove is fixedly arranged at the upper end of the base platform. A pushing device for driving the curing plate to move is fixedly arranged on one side of the base platform.

[0021] Further, the pushing device includes a pushing platform fixedly connected to one side of the base platform. A pushing electric cylinder is fixedly arranged on the pushing platform, and the output end of the pushing electric cylinder is fixedly connected to the curing plate.

[0022] By adopting the above technical solution, the fast response and stable movement characteristics of the pushing electric cylinder enable the curing plate to quickly reach the predetermined printing position and maintain a stable printing state. This helps to shorten the printing cycle and improve the printing efficiency. The automatic control of the translation device and the pushing device reduces the need for manual intervention. The operator only needs to set the printing parameters and path, and the device can automatically complete the printing process, thereby improving the usability and production efficiency of the device.

[0023] In summary, the present application includes the following beneficial technical effects: A 3D printing device that can quickly cure plastics into a high-temperature and high-pressure resistant shell, including a nozzle for spraying. A surrounding base bracket is arranged outside the nozzle. A top cover is fixedly arranged at the upper end of the base bracket. One side of the nozzle is communicated with a transportation pipeline, and the other end of the transportation pipeline is communicated with a storage tank fixedly connected to the top cover. The bottom of the nozzle is provided with a base platform fixedly connected to the middle of the base bracket. A curing plate for placing an object is arranged at the upper end of the base platform. A translation device for driving the movement of the curing plate is arranged on the base platform. An ultraviolet light assembly for improving the curing speed is arranged outside the nozzle. The raw material in the storage tank is transported to the nozzle through the transportation pipeline and sprayed onto the curing plate.

Detailed Implementation Manner

[0029] The following further elaborates on this application with reference to the accompanying drawings.

[0030] Example, referring to Figures 1-3 , a 3D printing device that can quickly cure plastic into a high-temperature and high-pressure resistant housing, including a nozzle 110 for spraying. A plurality of base brackets 1 for support are arranged outside the nozzle 110. A top cover 10 is fixedly arranged at the upper end of the base bracket 1. One side of the nozzle 110 is communicated with a transportation pipeline 61 for transporting raw materials. The other end of the transportation pipeline 61 is communicated with a storage box fixedly connected to the top cover 10. A base platform 11 fixedly connected to the middle of the base bracket 1 is arranged at the bottom of the nozzle 110. A curing plate 12 for placing the sprayed and printed object is arranged at the upper end of the base platform 11. A translation device for driving the curing plate 12 to move left and right is arranged on the base platform 11. An ultraviolet light assembly for improving the curing speed is arranged outside the nozzle 110.

[0031] The raw materials in the storage box are transported to the nozzle 110 through the transportation pipeline 61 and sprayed onto the curing plate 12. At this time, the ultraviolet light assembly outside the nozzle 110 will continuously irradiate the plastic material, thereby significantly improving the curing speed. The ultraviolet light assembly outside the nozzle 110 starts to play a key role. The high-power LED ultraviolet lamp strip emits ultraviolet light of a specific wavelength and continuously irradiates the sprayed plastic material. Ultraviolet light can enable plastic molecules to quickly connect to form a strong network structure, thereby significantly improving the curing speed. The light intensity of the ultraviolet light assembly can be adjusted according to the printing requirements to adapt to the requirements of different materials and printing layer thicknesses. The setting of the translation device further improves the printing path and printing efficiency.

[0032] In this embodiment, the ultraviolet light assembly includes connecting rods 4 arranged on both sides of the nozzle 110. Sliding rods 45 are installed on the connecting rods 4. The ends of the sliding rods 45 are fixedly connected to mounting plates 46, and ultraviolet lamp strips 49 are fixedly arranged on the mounting plates 46. A sliding frame 41 is slidably arranged on the sliding rod 45. The sliding frame 41 is slidably connected to the connecting rod 4. A micro motor 42 is fixedly connected to the sliding frame 41. A driving gear 43 is fixedly arranged on the output end of the micro motor 42. A driven gear bar 44 meshing with the driving gear 43 is fixedly arranged on the sliding rod 45.

[0033] In this embodiment, the ultraviolet lamp strip 49 is installed on the mounting plate 46 and is arranged outside the ultraviolet lamp strip 49. During the printing process, the printed item is continuously illuminated to improve curing. And according to the required light for the actual situation, through the micro motor 42, it can drive the driving gear 43 to rotate, thereby cooperating with the gear bar to move the sliding frame 41 on the sliding rod 45, so as to adjust the distance between the ultraviolet lamp strip 49 and the nozzle 110.

[0034] In this embodiment, a driving ring 35 is fixedly arranged between the connecting rods 4. A rotating groove for the driving ring 35 to rotate is opened on the outside of the nozzle 110. A rotating motor 36 is fixedly arranged on the driving ring 35. A rotating gear 37 is fixedly arranged on the output end of the rotating motor 36. A linkage gear 38 meshing with the rotating gear 37 is fixedly arranged on the nozzle 110.

[0035] The driving ring 35 fixedly arranged between the connecting rods 4 cooperates with the rotating groove opened on the outside of the nozzle 110, enabling the driving ring 35 to rotate on the nozzle 110. The rotating motor 36 fixed on the driving ring 35 meshes with the linkage gear 38 fixed on the nozzle 110 through the rotating gear 37 on its output end. When the rotating motor 36 works, the rotating gear 37 rotates accordingly, and drives the entire driving ring 35 to rotate on the nozzle 110 through gear transmission. Since the ultraviolet light assembly is connected to the driving ring 35, when the driving ring 35 rotates, the entire ultraviolet light assembly will also rotate accordingly. This rotation function enables the ultraviolet lamp strip 49 to irradiate the printed part more evenly, reducing the shadow area, thereby improving the curing quality and the consistency of the printed part.

[0036] In this embodiment, reflecting plates 40 connected to the mounting plate 46 are arranged on the upper and lower sides of the ultraviolet lamp strip 49. Rotating blocks 47 are fixedly connected to both ends of the mounting plate 46. A rotating shaft is fixedly connected to the reflecting plate 40. The rotating shaft is rotatably connected to the two end rotating blocks 47. A linkage motor 48 is fixedly arranged on the rotating block 47. The output end of the linkage motor 48 is fixedly connected to the rotating shaft.

[0037] The reflector plates 40 added on the upper and lower sides of the ultraviolet lamp strip 49 are driven by a linkage motor 48 with independent control, and can achieve multi-angle adjustment. The surface of the reflector plate 40 adopts an electroplated nickel substrate plus a silica dielectric film reflective layer, which can be applied to the elliptical focused light spot for line scanning curing, and the oblique light field formed by the deflection of the unilateral reflector plate 40, effectively solving the curing problem at the bottom of the overhanging structure. In terms of optimizing the curing process, the adjustment mechanism of the reflector plate 40 realizes the dynamic adjustment of the curing energy density, significantly improving the curing depth and the interlayer bonding strength. At the same time, the asymmetric light spot mode reduces the temperature gradient and residual stress.

[0038] In this embodiment, a damping piece fixedly connected to the reflector plate 40 is arranged on the rotating shaft.

[0039] In this embodiment, a sliding frame 3 is arranged at the upper end of the nozzle 110. A sliding shell 34 is slidably arranged on the sliding frame 3. The sliding shell 34 is fixedly connected to the nozzle 110. One end of the sliding frame 3 is rotatably connected to a driving shaft 32, and the other end is rotatably connected to a driven shaft 33. A moving belt 31 is sleeved on the driving shaft 32 and the driven shaft 33. One side of the sliding frame 3 is fixedly connected to the moving belt 31. A sliding motor is fixedly connected to the bottom of the sliding frame 3, and the output end of the sliding motor is connected to the driving shaft 32. By driving the driving shaft 32 to rotate with the sliding motor, the moving belt 31 is rotated, thereby driving the sliding frame 41 to move back and forth, making the printing path more precise, thus greatly improving the accuracy and surface quality of the printed parts. At the same time, the design of the sliding frame 3 enables the nozzle 110 to move freely within a larger range, easily adapting to printed parts of different sizes and shapes. This flexibility not only expands the application scenarios of the device but also improves the versatility of the device, enabling it to meet more diverse printing requirements. In addition, the drive of the sliding motor makes the movement of the nozzle 110 faster and more stable, effectively shortening the printing cycle and improving the printing efficiency.

[0040] In this embodiment, an adjustment motor 14 is arranged at the upper end of the sliding frame 3. The output end of the adjustment motor 14 is fixedly connected to the sliding frame 3. A push cylinder 13 is arranged at the upper end of the adjustment motor 14. The output end of the push cylinder 13 is fixedly connected to the adjustment motor 14, and the data push cylinder 13 is fixedly connected to the top cover. The setting of the push cylinder 13 is used to drive the nozzle 110 to move linearly up and down. At the same time, with the setting of the adjustment motor 14, the sliding frame 3 can be rotated, thereby driving it to perform multi-angle printing.

[0041] In this embodiment, referring to Figure 4, the translation device includes a groove formed at the bottom of the curing plate 12. A sliding protrusion that slides relative to the groove is fixedly provided at the upper end of the base platform 11. A pushing device for driving the movement of the curing plate is fixedly provided on one side of the base platform 11. The pushing device includes a pushing platform 5 fixedly connected to one side of the base platform 11. A pushing electric cylinder 51 is fixedly provided on the pushing platform 5, and the output end of the pushing electric cylinder is fixedly connected to the curing plate 12. The fast response and stable movement characteristics of the pushing electric cylinder 51 enable the curing plate 12 to quickly reach the predetermined printing position and maintain a stable printing state. This helps to shorten the printing cycle and improve the printing efficiency. The automatic control of the translation device and the pushing device reduces the need for manual intervention. The operator only needs to set the printing parameters and paths, and the device can automatically complete the printing process, thereby improving the usability and production efficiency of the device.

[0042] Specific implementation process: After entering the printing stage, the device starts to initialize. The nozzle 110 moves to the starting position driven by the sliding frame 3. At the same time, the ultraviolet light assembly is also adjusted to an appropriate position and angle to ensure uniform irradiation of the printing area. The plastic raw material in the storage tank is transported to the nozzle 110 through the transportation pipeline 61, and the nozzle 110 starts to spray the plastic onto the curing plate 12 according to the preset path. While spraying, the ultraviolet light assembly continuously irradiates the sprayed plastic, and uses the energy of the ultraviolet light to accelerate the curing process of the plastic.

[0043] To achieve complex printing paths and improve printing efficiency, the sliding frame 3 and the translation device work together. The sliding frame 3 drives the nozzle 110 to move in the X, Y, and Z directions, while the translation device drives the curing plate 12 to move on the base platform 11. Through the precise cooperation of the two, the nozzle 110 can spray plastic onto the curing plate 12 according to the preset path to form the required shape and structure.

[0044] During the printing process, the device will monitor the printing status in real time. For example, the temperature of the printed part is monitored by a temperature sensor, and the curing degree of the plastic is monitored by a curing depth sensor, etc. If it is found that the printed part is deformed, not fully cured or other abnormal situations occur, the device can automatically adjust the printing parameters, such as ultraviolet light intensity, spraying speed, etc., to ensure the smooth progress of the printing process and the quality of the printed part.

[0045] When the printing is completed, the device enters the post-processing stage. The nozzle 110 stops spraying, and the ultraviolet light assembly is also turned off. The sliding frame 3 drives the nozzle 110 to move to a safe position to avoid damaging the printed part. At the same time, the device performs automatic cleaning to remove the residual plastic raw material and curing agent. After the device cools down, the printed part on the curing plate 12 is taken out by the operator for necessary post-processing, such as removing the support structure, grinding the surface, etc. Finally, the printed part is inspected for quality to ensure that it meets the design requirements and usage standards.

[0046] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of the application. Therefore, any equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
