Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to a ceramic 3D printing device that utilizes a heating fan for drying. Background Technology

[0002] Existing 3D printers for ceramic printing use a print head to deposit ceramic materials (such as ceramic slurry or ceramic powder) layer by layer in the printing area to form the product. Their core function focuses on the precise stacking of materials to achieve the three-dimensional structure of ceramic products, but they lack specific design for the material drying process during printing.

[0003] Because ceramic materials (especially slurry-based materials) need to be gradually dried during the printing process to maintain shape stability, most existing 3D printers rely on natural drying or overall drying in the later stages. This can easily cause the undried interlayer materials to deform or collapse due to gravity or external forces, affecting the precision of the product.

[0004] Even though some simple drying devices are equipped with heating elements, their positions and angles are fixed, making it impossible to adjust the drying range according to the height and shape of the printed product. This can easily lead to problems such as insufficient or excessive drying in certain areas. A few adjustable-angle drying devices lack a reliable locking structure, which may cause the angle to shift due to equipment vibration during the printing process, thus disrupting the uniformity of drying. At the same time, the unreasonable layout of the heating elements and airflow guides results in low heat transfer efficiency, further affecting the drying effect. Therefore, it is necessary to develop a ceramic 3D printing device that utilizes a heated fan for drying. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figures 1-5 The diagram shows a structural schematic of an embodiment of a ceramic 3D printing device that utilizes a heating fan for drying, according to this utility model. Please refer to [link / reference]. Figures 1-5 This paper provides a detailed introduction to a ceramic 3D printing device that utilizes a heated fan for drying.

[0031] A ceramic 3D printing device that utilizes a heating fan for drying includes a 3D printer 100, a heating and drying mechanism 200, and a drive locking mechanism 300. The 3D printer 100 includes a frame 101 and a mounting platform 102 disposed on the frame 101. A printing area 103 is disposed on the mounting platform 102. A printer head 104 for 3D printing ceramics is disposed on the frame 101 above the printing area 103, and the movable area of ​​the printer head 104 is located above the printing area 103.

[0032] The heating and drying mechanism 200 includes first brackets 201 symmetrically arranged on the left and right sides of the top of the mounting platform 102. A rotating rod 202 is rotatably arranged between the two first brackets 201 on the same side via a bearing sleeve. A support rod 203 is fixedly arranged on the rod body of the rotating rod 202. Mounting plates 204 are fixedly arranged at equal intervals on the side wall of the support rod 203. A small electric heating fan 205 is fixedly arranged on the side of each mounting plate 204 near the printing area 103. The small electric heating fans 205 on the left and right sides are respectively spaced from the two sides of the printing area 103.

[0033] The drive locking mechanism 300 is used to drive the rotating rod 202 to rotate and lock, thereby adjusting the angle of the small electric heating fans 205 on both sides toward the printing area 103. The drive locking mechanism 300 includes a second bracket 301 fixed on the top of the mounting platform 102 on the left and right sides in front of the printing area 103. A transverse movable rod 302 is rotatably arranged between the two second brackets 301 through a bearing sleeve. A transmission bevel gear 303 is fixedly arranged at the left and right ends of the movable rod 302 respectively. The axes of the two rotating rods 202 are perpendicular to the axes of the transmission bevel gears 303. A driven bevel gear 304 that meshes with the two transmission bevel gears 303 is fixedly arranged at the front end of the two rotating rods 202 respectively.

[0034] Furthermore, the small electric heating fan 205 includes a perforated mounting shell 206. A servo motor and an electric heating tube are fixedly installed inside the mounting shell 206, and fan blades 207 are fixedly installed on the output shaft of the servo motor. The servo motor drives the fan blades 207 to rotate, while the electric heating tube generates heat, facilitating the formation of a hot airflow to dry the ceramic material in the printing area 103. The perforated mounting shell 206 promotes airflow and reduces obstruction during the hot airflow transfer process, thereby improving drying efficiency to a certain extent.

[0035] Furthermore, the electric heating tube is positioned at a distance from the fan blade 207, with the electric heating tube located between the fan blade 207 and the printing area 103. The airflow from the fan blade 207 is directed towards the printing area 103. This allows the airflow generated by the fan blade 207 to be heated by the electric heating tube before being blown towards the printing area 103, reducing heat loss during the transfer process and allowing the hot airflow to act more directly on the ceramic material, thus enhancing the drying effect.

[0036] Furthermore, the drive locking mechanism 300 also includes a worm gear 305 fixed in the middle of the movable rod 302. Two third supports 306 are fixedly installed in the front middle of the top wall of the mounting platform 102. The distance between the two third supports 306 is located in front of the printing area 103. A drive rod 307 is rotatably mounted above the worm gear 305 between the two third supports 306 via a bearing sleeve. A worm 308 that meshes with the worm gear 305 is fixedly installed on the body of the drive rod 307. Through the support of the third supports 306 for the drive rod 307 and the meshing transmission between the worm 308 and the worm gear 305, the driving force can be transmitted to the movable rod 302 more smoothly, which facilitates the control of the rotation of the rotating rod 202, thereby more accurately adjusting the angle of the small electric heating fan 205 and improving the convenience of angle adjustment.

[0037] Furthermore, a knob 309 protrudes from the front end of the drive rod 307, and the outer side of the knob 309 is provided with anti-slip texture. The knob 309 provides a convenient point of force for the operator to adjust the drive rod 307, and the anti-slip texture can increase the friction between the hand and the knob 309, reduce slippage during the adjustment process, and make the angle adjustment operation more effortless and stable.

[0038] Furthermore, the lead angle of the worm 308 is smaller than the equivalent friction angle between the teeth of the worm wheel 305, and the mechanism has self-locking properties, that is, the worm 308 can drive the worm wheel 305 to rotate, while the worm wheel 305 cannot drive the worm 308 in the opposite direction. This helps to maintain the stability of the small electric fan 205 after the angle adjustment is completed, reduces the angle deviation caused by external vibration and other factors, and improves the stability of the device during use.

[0039] The specific usage process of this ceramic 3D printing device that utilizes a heated fan for drying is as follows:

[0040] Preparation stage: Load the ceramic material to be printed into the print head 104 of the 3D printer 100, ensure that the printing area 103 on the mounting table 102 is clean and tidy, check whether each component is installed firmly, including whether the frame 101 supports the overall structure reliably, whether the first bracket 201, rotating rod 202, support rod 203, mounting plate 204 and small electric heating fan 205 of the heating and drying mechanism 200 are tightly connected, and whether the second bracket 301, movable rod 302, transmission bevel gear 303, driven bevel gear 304, worm gear 305, third bracket 306, drive rod 307, worm gear 308 and knob 309 of the drive locking mechanism 300 are in normal condition.

[0041] Adjusting the drying angle: According to printing requirements, the operator rotates the knob 309 at the front end of the drive rod 307, causing the drive rod 307 to rotate, which in turn drives the worm gear 308 on its body to rotate. Since the worm gear 308 meshes with the worm wheel 305 in the middle of the movable rod 302, the rotation of the worm gear 308 drives the worm wheel 305 and the movable rod 302 to rotate together. The transmission bevel gears 303 at both ends of the movable rod 302 rotate accordingly. Because the transmission bevel gears 303 mesh with the driven bevel gear 304 at the front end of the rotating rod 202, the rotating rod 202 begins to rotate under the transmission action, thereby causing the support rod 203, mounting plate 204, and small electric heating fan 205 on the rotating rod 202 to rotate synchronously, adjusting the angle of the small electric heating fan 205 towards the printing area 103. When the angle is appropriate, because the lead angle of the worm gear 308 is less than the equivalent friction angle between the teeth of the worm wheel 305, the worm gear mechanism has self-locking properties, locking the current angle.

[0042] Starting Printing and Drying: The 3D printer 100 is started, and the print head 104 begins ceramic 3D printing in the printing area 103. Simultaneously, the small electric heating fan 205 of the heating and drying mechanism 200 is turned on. A servo motor inside the mounting housing 206 of the small electric heating fan 205 drives the fan blades 207 to rotate. The airflow generated by the fan blades 207 is heated by the electric heating tube and then blown towards the printing area 103 to dry the ceramic material during the printing process.

[0043] Printing process monitoring: During the printing process, observe the printing status of printing area 103 and the drying effect of small electric heating fan 205. If the drying angle needs to be adjusted, the above angle adjustment steps can be repeated by turning knob 309.

[0044] Final stage: After printing is complete, first turn off the small electric heating fan 205, then turn off the 3D printer 100. After the device has cooled down, remove the printed ceramic product, clean and maintain the device, and ensure that each component can be used normally next time.

[0045] Furthermore, a description of the innovative aspects and substantial technical effects of this solution.

[0046] 1. Innovation Points

[0047] Synchronous drying design: Heating and drying mechanisms 200 are set on both sides of the printing area 103. The material is dried in real time during the ceramic printing process through a small electric heating fan 205, which breaks through the limitations of traditional 3D printers that only focus on material stacking and rely on post-drying.

[0048] Adjustable Angle Structure: Utilizing components such as the transmission bevel gear 303, driven bevel gear 304, worm gear 305, and worm 308 of the drive locking mechanism 300, the angle of the small electric heating fan 205 towards the printing area 103 can be adjusted. The rotating rod 202 is rotatably connected to the first bracket 201 via a bearing sleeve. Combined with the fixing structure of the support rod 203 and the mounting plate 204, the small electric heating fan 205 can adapt to the drying requirements of different printing stages and product shapes.

[0049] High-efficiency heat transfer layout: The electric heating element of the small electric fan 205 is located between the fan blade 207 and the printing area 103. The air from the fan blade 207 is heated before being blown towards the printing area 103, reducing heat loss; the hollow mounting shell 206 enhances airflow and improves heat transfer efficiency.

[0050] Self-locking stabilization mechanism: The lead angle of the worm 308 is less than the equivalent friction angle between the teeth of the worm wheel 305, forming a self-locking structure that can lock the angle of the small electric heating fan 205, avoid angle deviation caused by equipment vibration, and ensure drying stability.

[0051] 2. Substantial technical effects

[0052] Improve print quality: Real-time drying reduces defects such as interlayer deformation and collapse caused by ceramic materials (especially pastes) not drying in time, thereby improving the dimensional accuracy and structural integrity of printed products.

[0053] Enhanced Drying Targeting: The adjustable angle function allows the small electric heating fan 205 to precisely target different parts of the printing area 103, enabling differentiated drying for concave and convex structures of complex-shaped products, reducing the problem of insufficient or excessive drying in certain areas.

[0054] Improved drying efficiency: The reasonable hot airflow layout makes heat transfer more direct and shortens the drying time. At the same time, the small electric heating fans 205 symmetrically arranged on the left and right sides form a synergistic drying effect and improve the overall drying uniformity.

[0055] Ensuring operational stability: The self-locking mechanism ensures that the small electric heating fan maintains a stable 205° angle during printing, avoiding the drying effect due to angle deviation and reducing the printing failure rate.

[0056] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
