Abstract
Description
Technical Field
[0001] This application belongs to the field of 3D printing technology, specifically a 3D printing consumable color mixing device. Background Technology
[0002] 3D printing (3DP), 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] However, after a period of use, common color mixing devices accumulate a large amount of consumables on the internal shell and stirring mechanism, requiring staff to clean the inside of the device regularly. This not only increases labor costs but also requires disassembling the device before cleaning, which is inconvenient. Furthermore, repeated disassembly can cause varying degrees of wear and tear on the internal structure of the color mixing device, reducing its safety during use. Summary of the Invention
[0004] The purpose of this application is to provide a 3D printing consumable color mixing device in order to solve the problems mentioned above.
[0005] The technical solution adopted in this application is as follows: A 3D printing consumable mixing device includes a mixing tank, a motor is installed on the lower surface of the mixing tank, a worm gear is rotatably connected to the inner surface of the motor, a worm wheel is correspondingly meshed on one side surface of the worm gear, a drive shaft is installed on the inner surface of the worm wheel, a stirring rod is fixedly connected to the outer surface of the drive shaft, a fixing plate is installed on the outer surface of the drive shaft, a connecting plate is provided on the inner surface of the fixing plate, a cleaning plate is fixedly connected to the outer surface of the connecting plate, and a brush is installed on the outer surface of the cleaning plate.
[0006] By adopting the above technical solution, the installed motor drives the worm gear connected to the inner side to rotate, which in turn drives the worm wheel on one side to rotate. The rotation of the worm wheel drives the internal transmission shaft to rotate, which in turn drives the multiple stirring rollers installed on the outer side to rotate, thereby stirring the consumables inside the mixing tank. The set stirring mechanism not only makes the mixing more uniform but also improves the mixing effect, making it practical and adaptable. The rotation of the transmission shaft drives the upper and lower outer fixed plates to rotate, which in turn drives the inner connecting plate to rotate. This allows the outer cleaning plate to rotate along with the connecting plate. The rotation of the cleaning plate drives the outer brush to rotate, thereby enabling a more thorough cleaning of the inner wall of the mixing tank. Furthermore, the use of the water circulation mechanism in conjunction with the cleaning structure reduces water waste and improves the effectiveness of the mixing device, making it comprehensive and versatile.
[0007] In a preferred embodiment, a support rod is fixedly connected to the inner surface of the two connecting plates, a first buffer post is installed on the upper inner surface of the support rod, a first spring is provided on the lower surface of the first buffer post, and a second buffer post is installed on the lower surface of the first spring.
[0008] By adopting the above technical solution, the outer cleaning mechanism can operate more stably by installing a support rod on the lower surface of the connecting plate. The first buffer column, the first spring and the second buffer column installed inside the support rod can better distribute the pressure of the stirring mechanism and the cleaning mechanism during rotation, so as to avoid bending or deformation of the support rod during use, thus making it stable and protective.
[0009] In a preferred embodiment, a second spring is provided on the rear surface of the connecting plate, and a fixing block is connected to the rear surface of the second spring. The fixing block is fixedly installed inside the fixing plate.
[0010] By adopting the above technical solution, the first buffer column installed allows the connecting plate to extend during rotation. When the cleaning plate comes into contact with the inside of the mixing tank for cleaning, the pressure generated will push the connecting plate to extend inward, thereby driving the second spring to compress. This ensures that the cleaning mechanism will not damage the inside of the mixing tank during use. The installed fixing block makes the second spring more stable, giving it versatility and safety.
[0011] In a preferred embodiment, a support leg is installed on the lower surface of the mixing tank, and a base plate is provided on the lower surface of the support leg.
[0012] By adopting the above technical solution, the installed support legs can support the mixing tank above, making the mixing tank more stable during operation. The installed base plate can make the device above more stable and fixed during use.
[0013] In a preferred embodiment, the upper surface of the mixing tank is provided with a feed inlet, and the lower surface of the mixing tank is provided with a discharge pipe.
[0014] By adopting the above technical solution, the feed inlet with the through hole makes it easy for workers to put consumables into the mixing tank for color mixing. The installed discharge pipe can be used to discharge the consumables inside the mixing tank. A sealing cap is threaded on the outside of the discharge pipe. When no material needs to be discharged, the bottom of the discharge pipe can be sealed with the sealing cap to avoid waste of resources, making it convenient and practical.
[0015] In a preferred embodiment, a discharge pipe is provided on the lower surface of the mixing tank, and a control valve is installed on the outer surface of the discharge pipe.
[0016] By adopting the above technical solution, the installed discharge pipe can be used to transport waste generated during the cleaning process, and the installed control valve makes it easy for workers to open and close the discharge pipe. When discharge is not required, the control valve can be closed to complete the sealing, making it convenient and adaptable.
[0017] In a preferred embodiment, a recycling bin is mounted on the upper surface of the base plate, and a filter screen is provided on the upper inner surface of the recycling bin.
[0018] By adopting the above technical solution, the installed recycling bin can be used to recycle the cleaned waste and sewage, and the installed filter screen can be used to filter the consumable waste in the recycled waste and separate solids and liquids. This allows the cleaning unit to reuse the water flow, reducing water waste and making it practical and comprehensive.
[0019] In a preferred embodiment, a return pipe is connected to one side surface of the recycling bin, a water pump is installed on one end surface of the return pipe, an infusion pipe is connected to one end surface of the water pump, and one end of the infusion pipe is inserted into the interior of the color mixing tank.
[0020] By adopting the above technical solution, during the cleaning process, the water pump can be turned on to pump the filtered water inside the recycling tank into the mixing tank through the return pipe and the infusion pipe. This allows it to work in conjunction with the internal cleaning mechanism, thereby enabling a more comprehensive cleaning of the mixing tank and reducing water waste. It also makes the tank more versatile and adaptable.
[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: 1. The cleaning mechanism can clean the inside of the mixing tank, and the water circulation mechanism can reduce water waste. The cleaning mechanism can work in conjunction with the mixing and circulation mechanisms to improve the cleaning effect, reduce labor costs, and improve the ease of use of the mixing device.
[0022] 2. The stirring mechanism can stir the consumables inside the mixing tank, and during the stirring process, it can drive the cleaning mechanism to scrape off the material adhering to the inner wall surface of the mixing tank, thereby making the mixing more uniform and improving the mixing effect.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example
[0026] Reference Figures 1-4 A 3D printing consumable mixing device includes a mixing tank 1. A motor 17 is mounted on the lower surface of the mixing tank 1. A worm gear 16 is rotatably connected to the inner surface of the motor 17. A worm wheel 15 is correspondingly meshed with one side surface of the worm gear 16. A drive shaft 14 is mounted on the inner surface of the worm wheel 15. The motor 17 drives the inner worm gear 16 to rotate, which in turn drives the worm wheel 15 to rotate. The rotation of the worm wheel 15 drives the internal drive shaft 14 to rotate, which in turn rotates multiple stirring rollers 13 mounted on the outer side. This stirs the consumable inside the mixing tank 1. The stirring mechanism not only makes the mixing more uniform but also improves the mixing effect, making it practical and adaptable.
[0027] Reference Figures 1-4 A stirring rod 13 is fixedly connected to the outer surface of the drive shaft 14. A fixing plate 21 is installed on the outer surface of the drive shaft 14. A connecting plate 22 is provided on the inner surface of the fixing plate 21. A cleaning plate 19 is fixedly connected to the outer surface of the connecting plate 22. A brush 20 is installed on the outer surface of the cleaning plate 19. The rotation of the drive shaft 14 can drive the upper and lower outer fixed plates 21 to rotate, thereby driving the inner connecting plate 22 to rotate as well. This allows the outer cleaning plate 19 to rotate along with the connecting plate 22. The rotation of the cleaning plate 19 can drive the outer brush 20 to rotate, thus enabling a more thorough cleaning of the inner wall of the mixing tank 1. Furthermore, the use of the water circulation mechanism and the cleaning structure in combination can reduce water waste, improve the efficiency of the mixing device, and make it more comprehensive and versatile.
[0028] Reference Figures 4-5 Support rods 18 are fixedly connected to the inner surfaces of the two connecting plates 22. A first buffer column 23 is installed on the upper inner surface of the support rod 18, a first spring 24 is installed on the lower surface of the first buffer column 23, and a second buffer column 25 is installed on the lower surface of the first spring 24. By installing support rods 18 on the lower surface of the connecting plates 22, the outer cleaning mechanism can operate more stably. The first buffer column 23, the first spring 24, and the second buffer column 25 installed inside the support rod 18 can better distribute the pressure of the stirring and cleaning mechanisms during rotation, preventing the support rod 18 from bending or deforming during use, thus providing stability and protection.
[0029] Reference Figures 4-6A second spring 26 is provided on the rear surface of the connecting plate 22, and a fixing block 27 is connected to the rear surface of the second spring 26. The fixing block 27 is fixedly installed inside the fixing plate 21. The first buffer post 23 installed allows the connecting plate 22 to extend during rotation. When the cleaning plate 19 is in contact with the inside of the mixing tank 1 for cleaning, the pressure generated will push the connecting plate 22 to extend inward, thereby driving the second spring 26 to compress. This prevents the cleaning mechanism from damaging the inside of the mixing tank 1 during use. The fixed block 27 installed makes the second spring 26 more stable, giving it versatility and safety.
[0030] Reference Figures 1-2 A support leg 12 is installed on the lower surface of the mixing tank 1, and a base plate 2 is provided on the lower surface of the support leg 12. The installed support leg 12 can support the mixing tank 1 above, thereby making the mixing tank 1 more stable during operation. The installed base plate 2 can make the device above more stable and fixed during use.
[0031] Reference Figures 1-3 The mixing tank 1 has an inlet 7 on its upper surface and a discharge pipe 9 on its lower surface. The inlet 7 allows workers to easily add consumables into the mixing tank 1 for mixing. The discharge pipe 9 is used to discharge consumables from the mixing tank 1. A sealing cap is threaded onto the outside of the discharge pipe 9. When no material needs to be added, the bottom of the discharge pipe 9 is sealed with the sealing cap to avoid wasting resources, thus providing convenience and practicality.
[0032] Reference Figures 1-2 A discharge pipe 10 is installed on the lower surface of the color mixing tank 1, and a control valve 8 is installed on the outer surface of the discharge pipe 10. The discharge pipe 10 can be used to transport waste generated during the cleaning process, and the control valve 8 allows the staff to easily open and close the discharge pipe 9. When discharge is not required, the control valve 8 can be closed to seal the pipe, making it convenient and adaptable.
[0033] Reference Figures 1-2 A recycling bin 11 is installed on the upper surface of the base plate 2, and a filter screen 3 is installed on the upper surface of the inside of the recycling bin 11. The installed recycling bin 11 can be used to recycle the cleaned waste and sewage, and the installed filter screen 3 can be used to filter the consumable waste in the recycled waste and can separate solids and liquids, thereby enabling the cleaning mechanism to recycle water, reducing water waste and making it practical and comprehensive.
[0034] Reference Figures 1-2A return pipe 4 is connected to one side of the recycling bin 11. A water pump 5 is installed at one end of the return pipe 4, and an infusion pipe 6 is connected to one end of the water pump 5. One end of the infusion pipe 6 is inserted into the interior of the color mixing tank 1. During the cleaning process, by turning on the water pump 5, the filtered water inside the recycling bin 11 can be pumped into the interior of the color mixing tank 1 through the return pipe 4 and the infusion pipe 6. This allows it to work in conjunction with the internal cleaning mechanism, thereby enabling a more comprehensive cleaning of the interior of the color mixing tank 1, reducing water waste, and making it versatile and adaptable.
[0035] The implementation principle of the 3D printing consumable mixing device embodiment of this application is as follows: The installed motor 17 drives the inner worm gear 16 to rotate, which in turn drives the worm wheel 15 on one side to rotate. The rotation of the worm wheel 15 drives the internal transmission shaft 14 to rotate, which in turn drives the multiple stirring rollers 13 installed on the outside to rotate, thereby stirring the consumables inside the mixing tank 1. The set stirring mechanism not only makes the mixing more uniform, but also improves the mixing effect, making it practical and adaptable. The rotation of the transmission shaft 14 drives the upper and lower outer fixed plates 21 to rotate, which in turn drives the inner connecting plate 22 to rotate together. This allows the outer cleaning plate 19 to rotate together with the connecting plate 22. The rotation of the cleaning plate 19 drives the outer brush 20 to rotate, thereby enabling a more comprehensive cleaning of the inner wall of the mixing tank 1. Furthermore, the use of the water circulation mechanism and the cleaning structure in combination reduces water waste, improves the use effect of the mixing device, and makes it comprehensive and versatile.
