Description
Technical Field
[0001] This application relates to the technical field of material mixing, and in particular to a coaxial feeding and mixing device. Background Technology
[0002] In the production process, it is often necessary to mix multiple liquids together. When mixing material A and material B, material A needs to be stirred first, and then material B is gradually added to the container and stirred until it is evenly mixed.
[0003] In related technologies, a motor is generally used to drive the stirring fan blades that extend into the material cylinder to rotate, thereby stirring material A. Then, material B is poured in from the top opening of the material cylinder by hand, continuously stirring and mixing evenly.
[0004] Regarding the aforementioned technologies, the manual pouring method results in unstable pouring speed, requires a long mixing time, has a low degree of mixing, and is inconvenient for adding materials. Summary of the Invention
[0005] To facilitate material feeding, improve automation, and increase mixing efficiency, this application provides a coaxial feeding and mixing device.
[0006] The coaxial feeding and mixing device provided in this application adopts the following technical solution:
[0007] A coaxial feeding and mixing device includes a frame, on which a material hopper is mounted. A lid is coaxially mounted on the material hopper, and a feeding device is mounted on the lid. The discharge end of the feeding device is located at the bottom of the material hopper. A rotating shaft is also coaxially mounted on the lid, and multiple stirring blades are fixed on both sides of the rotating shaft in the radial direction. A driving device is mounted on the upper side of the lid, and the driving device drives the rotating shaft to rotate around its own axis. A lifting device is also mounted on the frame to drive the lid to move vertically.
[0008] By adopting the above technical solution, in actual operation, the worker directly pours material A into the container, places the container under the lid, and the lifting device moves the lid onto the container. The worker then starts the drive unit, which drives the rotating shaft, which in turn drives the stirring blades to agitate material A. Simultaneously, the worker uses the feeding device to pour different materials, such as material B, into the bottom of the container. The stirring blades continuously agitate, ensuring that materials A and B are thoroughly mixed. This method allows for better mixing of multiple materials, improving automation and mixing efficiency.
[0009] Preferably, the feeding device includes a pneumatic plunger pump, the pump body of which is fixed on the barrel cover, and a discharge pipe is connected to the discharge end of the pneumatic plunger pump. The discharge pipe is coaxially arranged with the barrel cover, and the lower end of the discharge pipe is set as the discharge end of the feeding device. The rotating shaft is coaxially sleeved on the outside of the discharge pipe.
[0010] By adopting the above technical solution, the discharge pipe, coaxially arranged with the rotating shaft, ensures that material B discharged from the discharge end can be quickly, stably, and uniformly mixed with material A in the material tank, without affecting the stirring space. The pneumatic plunger pump can precisely control the liquid flow rate, avoiding the instability that may be caused by traditional manual feeding, reducing the risk of leakage during operation, and is suitable for occasions with strict material requirements.
[0011] Preferably, a bearing seat is coaxially fixed to the lower side of the barrel lid, and a positioning shaft is coaxially arranged inside the bearing seat. Deep groove ball bearings are respectively arranged at both ends of the positioning shaft. The positioning shaft is fixedly connected to the inner ring of the two deep groove ball bearings through a shoulder. The outer ring of any deep groove ball bearing is pressed against the inner wall of the bearing seat. A planar thrust ball bearing is also arranged below the lower deep groove ball bearing. The upper side of the planar thrust ball bearing in the thickness direction is pressed against the lower part of the deep groove ball bearing, and the lower side is pressed against the bottom wall of the bearing seat. The rotating shaft is coaxially fixed to the positioning shaft. The discharge pipe passes through the bearing seat, the positioning shaft and the rotating shaft in sequence in the vertical direction.
[0012] By adopting the above technical solution, a bearing housing is fixed on the underside of the bucket lid. The bearing housing houses a positioning shaft, a deep groove ball bearing, and a thrust ball bearing, ensuring that the rotating shaft is coaxially fixed with the positioning shaft. This structure ensures stable operation of the rotating shaft and supports the operation of the entire mixing equipment. The bearing system guarantees the stability and precision of the rotating shaft, reduces mechanical wear, and extends the service life of the equipment. The configuration of deep groove ball bearings and flat thrust ball bearings improves the load-bearing capacity, effectively supporting the long-term operation of the mixing blades.
[0013] Preferably, the driving device includes a drive motor, the drive motor housing is fixed to the upper side of the bucket lid, a first sprocket is coaxially fixed on the output shaft of the drive motor, a second sprocket is coaxially fixed on the rotating shaft, and a synchronization chain is wound around the first sprocket and the second sprocket.
[0014] By adopting the above technical solution, the drive motor transmits power through a chain system, ensuring the smooth and efficient operation of the mixing system. The chain system allows the rotational speed of the shaft to be controlled by adjusting the motor speed, meeting the mixing requirements of different materials.
[0015] Preferably, the lifting device includes a telescopic cylinder, the cylinder body of which is fixed on the frame, the piston rod of which extends and retracts vertically upward, and the end of the piston rod is fixed relative to the bucket lid.
[0016] By adopting the above technical solution, the lifting device uses a telescopic cylinder. The piston rod of the telescopic cylinder drives the lifting and lowering of the bucket lid through vertical extension and retraction, thereby simplifying the bucket replacement process. The design of the telescopic cylinder makes the lifting and lowering of the bucket lid more stable, facilitating quick bucket replacement. It also simplifies the operation process, reduces manual intervention, and improves equipment efficiency.
[0017] Preferably, the frame is provided with a linear guide rail, and a slider is provided on the linear guide rail. The slider slides and engages with the linear guide rail in the vertical direction. The bucket lid is provided with a mounting bracket, which is fixedly connected to the end of the piston rod of the telescopic cylinder. The slider is fixedly connected to the mounting bracket. One linear guide rail and one slider are provided on each side of the telescopic cylinder.
[0018] By adopting the above technical solution, and by setting up linear guides and sliders, the connection structure between the telescopic cylinder and the lid is more stable, ensuring smooth movement of the lid during lifting and lowering. The combination of linear guides and sliders makes the lifting and lowering process of the lid more stable and precise, avoiding deviation or jamming. The precise cooperation between the linear guides and sliders ensures the stability and efficiency of the equipment during operation.
[0019] Preferably, a fixing frame is also fixed on the rotating shaft, with one fixing frame on each of the two radial sides of the rotating shaft. The ends of the plurality of stirring blades facing away from the rotating shaft are fixed on the corresponding fixing frames, and the side of any fixing frame facing away from the rotating shaft abuts against the inner wall of the material barrel.
[0020] By adopting the above technical solution, this design ensures the stability of the stirring blades and enables effective stirring within the hopper. The fixing frame keeps the stirring blades in a stable position, thus guaranteeing the uniformity and efficiency of the stirring. Simultaneously, the fixing frame, abutting against the inner wall of the hopper, helps reduce the occurrence of material remaining on the hopper's sidewall and not participating in the stirring process.
[0021] Preferably, the lower side of the material bucket is provided with a tray for preventing leakage, and the lower side of the tray is also fixed with multiple casters.
[0022] By adopting the above technical solutions, the pallet effectively prevents leakage of liquids or other materials, ensuring safety during operation. The casters design makes the equipment more flexible during use, allowing for easy position adjustment.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By employing a pneumatic plunger pump and a rotating shaft to drive the mixing blades, different materials (such as material B) can be added to the hopper stably and evenly, achieving efficient mixing. The automated feeding device and mixing system avoid the instability of manual feeding, thereby significantly improving mixing efficiency and automation, reducing manual intervention, and ensuring faster and more uniform mixing results;
[0025] 2. The lifting device uses a telescopic cylinder, combined with a linear guide rail and slider structure, making the lifting and lowering process of the bucket lid smoother and more precise. This design simplifies the bucket replacement process, allowing operators to change buckets more easily and reducing manual intervention during operation. At the same time, the telescopic cylinder and linear guide rail work together to improve the efficiency and stability of equipment operation;
[0026] 3. The design incorporates a leak-proof tray and casters, making the equipment safer during feeding or mixing and reducing the risk of liquid or other material leakage. The tray effectively prevents liquid leakage, while the casters make the equipment more flexible, easy to move and adjust its position. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0031] This application discloses a coaxial feeding and mixing device.
[0032] See Figure 1 , Figure 2The coaxial feeding and mixing equipment includes a frame 1, with trays 7 arranged between the frame 1 sections. Multiple casters 71 are fixed to the underside of the trays 7. A material bucket 2 is placed on the upper side of the trays 7. A lid 6 is installed on the upper side of the material bucket 2. A lifting device 3 is installed on the frame 1, which drives the lid 6 to slide vertically and cover the material bucket 2. A feeding device 5 and a driving device 4 are also installed on the lid 6. A rotating shaft 65 is located on the lower side of the lid 6 in the thickness direction, and the driving device 4 drives the rotating shaft 65 to rotate around its own axis. A fixing frame 652 is also fixed on the rotating shaft 65. There is one fixing frame 652 on each side of any radial direction of the rotating shaft 65. Multiple stirring blades 653 are arranged in any fixing frame 652. The multiple stirring blades 653 in the fixing frame 652 on any side are evenly spaced in the vertical direction. The end of the multiple stirring blades 653 away from the rotating shaft 65 is fixed on the corresponding fixing frame 652. The side of any fixing frame 652 away from the rotating shaft 65 abuts against the inner wall of the material barrel 2.
[0033] In practice, the worker places the bucket 2 containing material A on the tray 7, and pushes the tray 7 to move it under the lid 6. The lifting device 3 lowers the lid 6 until it covers the bucket 2. The rotating shaft 65 and the stirring blade 653 are inserted into the bucket 2. The lid 6 and the bucket 2 are coaxially arranged, and any fixed frame 652 on the side opposite to the rotating shaft 65 abuts against the side wall of the bucket 2. The worker starts the drive device 4, which drives the rotating shaft 65 to rotate. At the same time, the worker adds materials such as material B into the bucket 2 through the feeding device 5, and the stirring blade 653 mixes the various materials.
[0034] A bearing housing 61 is coaxially fixed to the lower side of the bucket lid 6. A positioning shaft 64 is coaxially arranged inside the bearing housing 61. Deep groove ball bearings 62 are respectively arranged at both ends of the positioning shaft 64. The positioning shaft 64 is fixedly connected to the inner ring of the two deep groove ball bearings through the shaft shoulder. The outer ring of any deep groove ball bearing 62 is pressed against the inner wall of the bearing housing 61. A planar thrust ball bearing 63 is also arranged below the lower deep groove ball bearing 62. The upper side of the planar thrust ball bearing 63 in the thickness direction is pressed against the lower part of the lower deep groove ball bearing, and the lower side is pressed against the bottom wall of the bearing housing 61. The rotating shaft 65 is coaxially fixed with the positioning shaft 64. Multiple weight reduction grooves 651 are also formed on the rotating shaft 65.
[0035] The drive device 4 includes a drive motor 41, the housing of which is fixed to the upper side of the lid 6. A first sprocket 42 is coaxially fixed to the output shaft of the drive motor 41, and a second sprocket 43 is coaxially fixed to the positioning shaft 64. A synchronization chain 44 is wound around the first sprocket 42 and the second sprocket 43. The rotation of the drive motor 41 drives the first sprocket 42 to rotate, which in turn drives the synchronization chain 44, which in turn drives the second sprocket 43 to rotate. The second sprocket 43 drives the positioning shaft 64 to rotate, thereby driving the rotating shaft 65 to rotate.
[0036] The feeding device 5 includes a pneumatic plunger pump 51. The pump body of the pneumatic plunger pump 51 is fixed on the barrel cover 6. The discharge end of the pneumatic plunger pump 51 is connected to a discharge pipe 52, which is coaxially arranged with the barrel cover 6. The lower end of the discharge pipe 52 is located at the bottom of the material barrel 2. The discharge pipe 52 passes through the bearing seat 61, the positioning shaft 64, and the rotating shaft 65 in a vertical direction. In actual operation, the operator feeds the material to be added through the feed end of the pneumatic plunger pump 51, and the pneumatic plunger pump 51 drives the material to be added to be discharged into the material barrel 2 from the lower end of the discharge pipe 52.
[0037] The lifting device 3 includes a telescopic cylinder 31, the cylinder body of which is fixed to the frame 1.

A linear guide rail 32 is provided on the frame 1, and a slider 33 is provided on the linear guide rail 32. The slider 33 slides and engages with the linear guide rail 32 vertically, and is fixedly connected to the mounting bracket 11. One linear guide rail 32 and one slider 33 are provided on each side of the telescopic cylinder 31. The extension and retraction of the piston rod of the telescopic cylinder 31 drives the mounting bracket 11, thereby causing the bucket lid 6 to slide vertically. The linear guide rail 32 and the slider 33 ensure the stability and efficiency of the bucket lid 6 during the lifting and lowering process.
[0038] The implementation principle of a coaxial feeding and mixing device according to an embodiment of this application is as follows: The operator places a bucket 2 containing material A on a tray 7, pushes the tray 7 to the underside of the bucket lid 6, and the telescopic cylinder 31 drives the mounting frame 11 to slide downwards vertically. The mounting frame 11 drives the bucket lid 6 downwards. The operator pushes the tray 7 to ensure that the bucket lid 6 and the bucket 2 are coaxially aligned. The rotating shaft 65 is inserted vertically downwards into the bucket 2. The operator starts the drive motor 41, which drives the first sprocket 42 to rotate. Through the synchronous chain 44, the first sprocket 42 is driven to rotate, thereby driving the positioning shaft 64 to rotate. The positioning shaft 64 drives the rotating shaft 65 to rotate, and the rotating shaft 65 drives the mixing blades 653 to rotate. Simultaneously, the operator introduces material B through a pneumatic plunger pump 51 into the discharge pipe 52, and then discharges it into the bucket 2 from the lower end of the discharge pipe 52. The rotating blades 653 rotate, mixing material A and material B.
