Description

Technical Field

[0001] The utility model relates to the technical field of stirring mechanisms, in particular to a stirring mechanism for a printer resin tank. Background Technique

[0002] The printer resin tank is a core component in a stereolithography 3D printer, specifically used for storing and preserving liquid photosensitive resin. This resin undergoes a curing reaction when irradiated with light of a specific wavelength, thereby enabling the layer-by-layer construction of 3D printing. The design of the resin tank needs to consider its sealing performance, corrosion resistance, and compatibility with the printer to ensure the stability and accuracy of the printing process.

[0003] During the stereolithography 3D printing process, the resin material in the printer resin tank needs to maintain uniform properties and states to ensure the stability and reliability of the printing quality. However, in actual applications, the resin in the resin tank often tends to precipitate, stratify, or be unevenly distributed. Existing traditional resin tanks usually do not have a stirring mechanism, resulting in defects in the printed products, such as insufficient local strength and rough surfaces. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the above-mentioned equipment is in use, due to the lack of a stirring mechanism in the printer resin tank during the use process, defects exist in the printed products, and thus a stirring mechanism for a printer resin tank is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A stirring mechanism for a printer resin tank includes two support frames. A resin tank body is fixedly installed between the tops of the two support frames. Two mounting holes are opened at the bottom of the resin tank body. Ball bearings are fixedly inserted into the inner walls of the two mounting holes. Stirring shafts are fixedly inserted into the inner walls of the two ball bearings. Transmission gears are fixedly sleeved on the outer surfaces of the two stirring shafts. A first bevel gear is fixedly sleeved on the outer surface of one of the two stirring shafts. A second bevel gear is meshed with the outer surface of the first bevel gear. A rotating shaft is fixedly inserted into the inner wall of the second bevel gear. A bearing seat is fixedly sleeved on the outer surface of the rotating shaft, and the bottom of the resin tank body is fixedly connected to the top of the bearing seat. A driving motor is fixedly connected to one side of the outer wall of the rotating shaft.

[0006] Preferably, a group of card slots are opened on the outer surfaces of the two stirring shafts, and blocks are movably inserted into the inner walls of the two groups of card slots.

[0007] Preferably, a rotating disk is fixedly connected between the outer surfaces of the two groups of blocks.

[0008] Preferably, six stirring blades are fixedly connected to the outer surfaces of the two rotating disks.

[0009] Preferably, fixed rings are fixedly sleeved on the outer surfaces of both of the stirring shafts.

[0010] Preferably, a set of threaded grooves are formed at the tops of both of the fixed rings.

[0011] Preferably, hexagon head bolts are threadedly connected to the inner surfaces of both sets of threaded grooves.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] 1. In the present utility model, under the interaction of the components of the device, by the drive of the drive motor and through the meshing transmission of two transmission gears, the two stirring shafts rotate in opposite directions, and then the two rotating disks drive six stirring blades to perform efficient stirring in opposite directions respectively.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1-4 shown, the present utility model provides a stirring mechanism for a printer resin tank, which includes two support frames 1. A resin tank body 2 is fixedly installed between the tops of the two support frames 1. Two installation holes 3 are opened at the bottom of the resin tank body 2. Ball bearings 4 are fixedly inserted into the inner walls of the two installation holes 3. Stirring shafts 5 are fixedly inserted into the inner walls of the two ball bearings 4. Transmission gears 6 are fixedly sleeved on the outer surfaces of the two stirring shafts 5. A first bevel gear 7 is fixedly sleeved on the outer surface of one of the two stirring shafts 5. A second bevel gear 8 is meshed and connected to the outer surface of the first bevel gear 7. A rotating shaft 9 is fixedly inserted into the inner wall of the second bevel gear 8. A bearing seat 10 is fixedly sleeved on the outer surface of the rotating shaft 9. And the bottom of the resin tank body 2 is fixedly connected to the top of the bearing seat 10. A driving motor 11 is fixedly connected to one side of the outer wall of the rotating shaft 9.

[0024] The overall effect achieved by the entire Embodiment 1 is that when it is necessary to stir the resin inside the resin tank body 2, first start the driving motor 11. The output end of the driving motor 11 drives the rotating shaft 9 to rotate. This power is converted into a rotating motion of one stirring shaft 5 through the meshing transmission of the first bevel gear 7 and the second bevel gear 8. At the same time, due to the interaction of the two transmission gears 6, the other stirring shaft 5 rotates in the opposite direction, so that the two rotating disks 14 drive the six stirring blades 15 to stir in the opposite directions respectively, realizing the all-round and uniform mixing of the resin in the tank. This design of double-shaft stirring and opposite directions can effectively avoid the generation of dead angles of the resin in the tank, ensure the uniformity and fluidity of the resin, thereby improving the stability and reliability during the printing process. At the same time, it also helps to prevent resin precipitation and stratification, reduce printing defects such as insufficient local strength and rough surface, and ultimately improve the quality and consistency of the printed products.

[0025] Embodiment 2, as Figures 2-4As shown in the figure, a set of clamping grooves 12 are formed on the outer surface walls of both stirring shafts 5. A clamping block 13 is movably inserted into the inner surface walls of the two sets of clamping grooves 12. A rotating disk 14 is fixedly connected between the outer surface walls of the two sets of clamping blocks 13. Six stirring blades 15 are fixedly connected to the outer surface walls of the two rotating disks 14. Fixed rings 16 are fixedly sleeved on the outer surface walls of the two stirring shafts 5. A set of threaded grooves 17 are formed at the tops of the two fixed rings 16. Hexagonal bolts 18 are threadedly connected to the inner surface walls of the two sets of threaded grooves 17.

[0026] The overall effect achieved by the entire Embodiment 2 is that when it is necessary to replace or maintain the rotating disk 14 and the stirring blades 15, by loosening the two hexagonal bolts 18, the rotating disk 14 can be easily disassembled from the stirring shaft 5. This design realizes the quick disassembly and installation of the rotating disk 14, greatly facilitating the maintenance and servicing of the equipment. During the disassembly process, the loosening of the hexagonal bolts 18 makes the connection between the rotating disk 14 and the stirring shaft 5 become loose, thereby allowing the rotating disk 14 to be easily removed. At the same time, in order to ensure that the rotating disk 14 can rotate stably and synchronously with the stirring shaft 5 during the rotation of the stirring shaft 5, a precise matching mechanism of the clamping groove 12 and the clamping block 13 is adopted. This matching method not only ensures the stability of rotation but also enhances the connection strength between the rotating disk 14 and the stirring shaft 5. When the rotating disk 14 is reinstalled on the stirring shaft 5, the tight fit between the clamping groove 12 and the clamping block 13 can ensure that the rotating disk 14 does not displace or shake during the stirring process, thus ensuring the uniformity and effectiveness of stirring.

[0027] Working principle: During use, when the resin in the resin tank body 2 appears in a state of precipitation, stratification, or uneven distribution, these phenomena will directly affect the printing quality. Therefore, it is necessary to stir the resin in a timely manner. At this time, start the drive motor 11, and its output end rotates to drive the rotating shaft 9 to start rotating. The rotation of the rotating shaft 9 is transmitted to the first bevel gear 7 through the precise meshing transmission of the first bevel gear 7 and the second bevel gear 8, thereby driving a stirring shaft 5 fixedly connected inside it to rotate synchronously. At the same time, the two transmission gears 6 work in a meshing manner. Since the inner surface walls of the two transmission gears 6 are fixedly inserted with stirring shafts 5, this design enables the other stirring shaft 5 to rotate in the opposite direction under the drive of the transmission gears 6. With the synchronous but reverse rotation of the two stirring shafts 5, the two rotating disks 14 drive the six stirring blades 15 to stir efficiently in opposite directions. This dual-shaft reverse stirring mechanism effectively promotes the all-round mixing of the resin in the resin tank, ensuring the uniformity and fluidity of the resin. When it is necessary to replace or maintain the rotating disk 14 and the stirring blades 15, by simply loosening the two hexagonal bolts 18 on the connecting components, the rotating disk 14 can be easily separated from the stirring shaft 5. This design realizes the quick disassembly and installation of the rotating disk 14, thus simplifying the maintenance process and improving work efficiency.

[0028] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
