Description

Technical Field

[0001] This utility model relates to the field of powder kneading technology, specifically a powder kneading machine for rapid fiberization. Background Technology

[0002] A powder kneader is a mixing device that promotes the efficient transformation of powder materials into fibrous forms. Its core technology lies in achieving the directional arrangement and structural reconstruction of powder through mechanical shearing and thermal coupling. It mainly generates a multi-directional shear force field through the high-speed rotation of twin screws. Under the action of centrifugal force and frictional heat, the powder particles soften on the surface. When adjacent particles collide, the molecular chains become entangled, forming a continuous fibrous structure.

[0003] Traditional kneaders, particularly twin-screw kneaders, have a two-shaft kneading mechanism that can only achieve a single material convection model. Furthermore, the effective kneading area has a low volume ratio, leading to the formation of regular accumulation zones and concentrated laminar pressure during the kneading process. This results in slow fiberization efficiency and long processing time.

[0004] Therefore, it is necessary to provide a powder kneader for rapid fiberization to solve the problems mentioned in the background art. Utility Model Content

[0021] Please see Figures 1-5 In this embodiment of the present invention, a powder kneading machine for rapid fiberization includes a frame 1, a reducer 2, a sliding bearing 3, a torque limiter 4, a differential gearbox 5, and a kneading assembly 6. The reducer 2 is fixedly mounted on the frame 1 and is drivenly connected to the differential gearbox 5. A sliding bearing 3 and a torque limiter 4 are provided between the differential gearbox 5 and the reducer 2. The sliding bearing 3 is rotatable and is equipped with a rotatable cylinder. The kneading assembly 6 is drivenly connected to the differential gearbox 5. In other words, the rotatable cylinder can drive the entire machine to rotatable, thereby facilitating feeding and discharging.

[0022] The kneading assembly 6 includes a kneading shell 61, a temperature control jacket 62, a pressure plate 63, a pressure cover 64, a kneading mechanism one 65, and a kneading mechanism two 66. The kneading shell 61 forms a kneading cavity, in which the temperature control jacket 62 is disposed. The pressure plate 63 is slidably disposed in the kneading shell 61. The pressure cover 64 is flipped on the top of the kneading shell 61. A flipping cylinder two for driving the pressure cover 64 to flip is fixedly disposed on the shell 61. A pneumatic cylinder 67 for driving the pressure plate 63 to slide is fixedly disposed on the pressure cover 64. A limit plate is disposed between the pneumatic cylinder 67 and the pressure cover 64. The kneading mechanism one 65 and the kneading mechanism two 66 are rotatably disposed in the kneading shell 61.

[0023] In other words, the flipping cylinder can drive the pressure cover 64 to flip open, which is convenient for feeding materials. When the pneumatic cylinder 67 drives the pressure plate 63 to slide, the limiting plate can restrict the pressure cover 64, so that the pressure cover 64 cannot be opened, thereby improving the safety of operation.

[0024] The kneading mechanism 65 includes a rotating shaft 651 and kneading blades 652. The rotating shaft 651 is connected to the differential gearbox 5 for transmission. Two kneading blades 652 are fixedly arranged in a circular shape at both ends of the rotating shaft 651.

[0025] The kneading mechanism 2 66 includes a rotating shaft 2 661 and kneading blades 2 662. The rotating shaft 2 661 is connected to the differential gearbox 5 for transmission. Two kneading blades 2 662 are fixedly arranged in a circular shape at both ends of the rotating shaft 2 661.

[0026] Both the first kneading blade 652 and the second kneading blade 662 are spiral blades. The two kneading blades 652 located at both ends of the first rotating shaft 651 extend spirally inward from the end of the first rotating shaft 651, and with the center plane of the first rotating shaft 651 as the reference plane, the spiral directions of the kneading blades 652 at both ends of the first rotating shaft 651 are opposite.

[0027] The two kneading blades 662 located at both ends of the rotating shaft 661 extend spirally inward from the ends of the rotating shaft 661, and with the center plane of the rotating shaft 661 as the reference plane, the kneading blades 662 at both ends of the rotating shaft 661 have opposite spiral directions.

[0028] In other words, when the rotation of the first rotating shaft 651 and the second rotating shaft 661 drives the first kneading blade 652 and the second kneading blade 662 to rotate, the part of the first kneading blade 652 located at the end of the first rotating shaft 651 will preferentially knead with the part of the second kneading blade 662 located at the end of the second rotating shaft 662. Then, as the first rotating shaft 651 and the second rotating shaft 661 rotate, the first kneading blade 652 and the second kneading blade 662 knead from the outside to the inside, and push the material towards the middle part of the first rotating shaft 651 and the second rotating shaft 661. The material is pushed from both ends of the kneading blades 652 at both ends of the rotating shaft 651. The kneading blades 652 extend spirally from the ends of the rotating shaft 651 toward the middle of the rotating shaft 651, and the spiral direction is opposite to the rotation direction of the rotating shaft 651. Therefore, the two kneading blades 652 at both ends of the rotating shaft 651 can be regarded as two blades arranged in opposite directions. Similarly, the two kneading blades 662 at both ends of the rotating shaft 661 are also arranged in opposite directions, so as to push the material from both ends of the kneading shell 61 toward the middle.

[0029] The first kneading blade 652 has two arc-shaped convex surfaces, and the second kneading blade 662 is composed of an arc-shaped convex surface and an arc-shaped concave surface. The arc-shaped concave surface of the second kneading blade 662 is in contact with one of the arc-shaped concave surfaces of the first kneading blade 652. The two kneading blades 652 located at the same end of the first shaft 651 and the second shaft 661 have opposite spiral directions to the second kneading blade 662 and rotate and mesh.

[0030] The bottom of the kneading shell 61 is provided with a discharge port, and a discharge cavity 7 is provided below the discharge port. A baffle 611 is slidably provided at the discharge port, and a discharge screw 71 is rotatably provided in the discharge cavity 7.

[0031] In implementation, the reducer 2 provides power to the kneading assembly 6, causing the kneading mechanism 65 and kneading mechanism 66 in the kneading assembly 6 to rotate and knead the material. During the kneading process, the kneading blades 652 and 662 push the material from the end of the kneading shell 61 to the middle part of the kneading shell 61, and knead the material in this cyclical manner. That is, the material can form a kneading cycle from the outside to the inside inside the kneading shell 61, thereby avoiding the formation of regular accumulation areas in the kneading cavity, ensuring that all the material is kneaded, and avoiding the problem of laminar pressure concentration, thus effectively improving the kneading efficiency of the material, that is, improving the fiberization efficiency of the material. During the kneading process, the pressure plate 63 adjusts the pressure to press down the material, thereby ensuring that the material kneading pressure is a constant value and fully participates in the kneading. When the material is kneaded, the baffle 611 is slid open, allowing the material to be discharged from the discharge port into the discharge chamber 7, and the material is conveyed out by the rotation of the discharge screw 71, thereby realizing the automatic discharge of the material.

[0032] In summary, when implemented, the present invention uses spirally arranged kneading blades 652 and 662 to push the material from both ends of the kneading shell 61 toward the center during kneading, preventing the formation of regular accumulation zones and avoiding the problem of laminar pressure concentration, thereby effectively improving the kneading efficiency. In addition, the torque limiter 4 can disconnect the transmission when the torque reaches the threshold, thus ensuring that the equipment is not damaged during use and extending its service life.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
