Technical Field
[0001] The invention relates to the technical field of powder granulation, in particular to a powder granulation device and a method for producing plant extracts. Background Art
[0002] Plant extracts are ingredients with specific biological activity extracted from plants, and there are many types, including alkaloids, flavonoids, terpenes, polysaccharides, etc. Different plant extracts have different physical and chemical properties, such as particle size, density, solubility, stability, etc. Modern granulation technology includes wet granulation, dry granulation, spray granulation and other methods, which can meet the granulation needs of different types of plant extracts. In the granulation process of plant extract powder, liquid is generally added to the powder to mix to form a powder mass, and then it is produced into granules through granulation equipment.
[0003] At present, in the granulation process of plant extract powder, it is necessary to stir the plant extract powder with additives such as binders. Some materials stick to the inner wall, resulting in insufficient mixing, which affects the consistency of product quality. The powder is then manually sprayed with liquid, which easily leads to problems with inaccurate control of the spraying amount, resulting in the powder and liquid not being able to fully contact and mix evenly. At the same time, if the accumulated powder is large in number and high in height, the powder on the bottom layer cannot fully contact the liquid, which easily leads to a problem of reduced granulation efficiency. Summary of the invention

The motor is connected to an external power supply to work, the motor drives the rotating shaft to rotate, and the rotating shaft drives the straight rod and the spiral plate to rotate, and then the spiral plate stirs the internal powder and adhesive evenly to make them fully mixed, which helps to form particles with uniform structure. The proportion of ingredients in each particle is basically the same, thereby ensuring the consistency of product quality. There are two spiral plates, and the two spiral plates are evenly distributed with the rotating shaft as the center. A fixing ring is fixedly connected to the middle of one end of the straight rod away from the rotating shaft, and a pressure plate is rotatably connected to the outer side of the fixing ring, and the pressure plate is magnetic.

When the rotating shaft speed increases, the slider drives the bent plate to slide inside the square groove under the action of centrifugal force, and the bent plate is stretched. At this time, the slider exerts a force on one side of the pressing plate, so that the pressing plate is rotated under the force. At this time, the smaller the inclination angle of the pressing plate, the greater the extrusion pressure, so that the material can be extruded smoothly, and a higher pressure needs to be provided to overcome the increased resistance. At the same time, the smaller the inclination angle, the surface of the long strip material may be smoother, and the material is subjected to more uniform extrusion and friction during the extrusion process, reducing the generation of surface flaws and defects.

The continuity is destroyed, thereby causing the liquid to disperse into fine water droplets, which are then sprayed out from the circular hole to mix with the powder inside the cylinder. The circular tube rotates with the shaft, so that the liquid is sprayed out evenly to avoid the powder and liquid not being able to fully contact and mix evenly. At the same time, it can also prevent the accumulation of too much and high powder, so that the powder at the bottom cannot be fully in contact with the liquid, which is prone to reduce the granulation efficiency. The spiral groove is connected to the circular hole on the circular tube, and the circular tube is fixedly connected to the outside of the cylinder close to an arc plate, and the arc plate is symmetrically arranged with the circular hole as the center. The arc plate is located inside the cylinder, and the opposite side of the arc plate is fixedly connected to a square plate, and the square plates are alternately arranged on the arc plate.

The outer side of the V-shaped plate is fixedly connected with a baffle. There are two baffles. The baffle is an L-shaped plate. The baffle is located inside the discharge hole. The V-shaped plate is located inside the through hole. The inner wall of the feed hopper is fixedly connected with a fixed frame.

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
[0018] The first embodiment, as Figures 1 to 4 As shown, the present invention provides a technical solution: a powder granulation device and method for plant extracts, comprising a frame 1, a shell 2 is fixedly installed on the top of the frame 1, a motor 3 is fixedly connected to the outside of the shell 2, and a feed pipe 5 is fixedly connected to the bottom of the shell 2; A feed assembly 4, which is fixedly mounted on the top of the housing 2, and the feed assembly 4 and the feed pipe 5 are located on the same vertical plane; A granulation assembly 6, which is arranged inside the housing 2 and is fixedly connected to an output end of the motor 3; The shell 2 includes an outer shell 21, which is fixedly connected to the frame 1. A cylinder 22 is fixedly connected to the inside of the outer shell 21. A filter hole is provided on the outside of the cylinder 22. The granulation assembly 6 is located inside the cylinder 22. An elastic plate 23 is fixedly connected to the inner wall of the outer shell 21 close to the cylinder 22. A magnetic block 24 is fixedly connected to the end of the elastic plate 23 away from the outer shell 21. The magnetic properties of the magnetic block 24 and the pressing plate 66 are opposite. The magnetic block 24 is located at the side of the filter hole. After the powder and the binder are evenly mixed, the mixture is extruded through the filter hole on the cylinder 22 under the pressure and centrifugal force of the pressing plate 66. As the rotating shaft 61 drives the pressing plate 66 to rotate, when the pressing plate 66 approaches the magnetic block 24, the magnetic block 24 moves under the mutual attraction between the pressing plate 66 and the magnetic block 24, and the elastic plate 23 is stretched by force, so that the long strips extruded from the filter hole are cut off to form particles. Under the elastic force of the elastic plate 23, the magnetic block 24 is reset and contacts the outer side of the cylinder 22. The granulation assembly 6 includes a rotating shaft 61, which is fixedly connected to the output end of the motor 3. A spray assembly 64 is fixedly connected to the outer side of the rotating shaft 61. A straight rod 62 is fixedly connected to the outer side of the spray assembly 64. The straight rod 62 is symmetrically arranged on the outer side of the rotating shaft 61. A spiral plate 65 is fixedly connected to the outer side of the straight rod 62. The powder is added to the interior of the cylinder 22 through the feeding assembly 4. The motor 3 is connected to an external power supply to work. The motor 3 drives the rotating shaft 61 to rotate. The rotating shaft 61 drives the straight rod 62 and the spiral plate 65 to rotate, and then the spiral plate 65 stirs the internal powder and adhesive evenly to make them fully mixed, which helps to form particles with uniform structure. The proportion of components in each particle is basically the same, thereby ensuring the consistency of product quality. There are two spiral plates 65, and the two spiral plates 65 are evenly distributed with the rotating shaft 61 as the center. A fixing ring 63 is fixedly connected to the middle of one end of the straight rod 62 away from the rotating shaft 61. A pressing plate 66 is rotatably connected to the outer side of the fixing ring 63, and the pressing plate 66 is magnetic.
[0019] There are multiple pressing plates 66, which are evenly distributed around the fixing ring 63. The side of the pressing plate 66 close to the cylinder 22 is set to be arc-shaped. The two ends of the pressing plate 66 are rotatably connected to the fixing rings 63 on both sides. A square groove 67 is opened on the side of the straight rod 62 close to the pressing plate 66. A bent plate 68 is fixedly connected to the inner wall of the square groove 67. When the rotation speed of the rotating shaft 61 increases, the slider 69 drives the bent plate 68 to slide inside the square groove 67 under the action of centrifugal force. The bent plate 68 is stretched by force. At this time, the slider 69 pushes one side of the pressing plate 66 The force applied from the side causes the pressure plate 66 to rotate under the force. At this time, the smaller the inclination angle of the pressure plate 66, the greater the extrusion pressure, so that the material can be extruded smoothly. Higher pressure needs to be provided to overcome the increased resistance. At the same time, the smaller inclination angle may make the surface of the long strip material smoother, and the material is subjected to more uniform extrusion and friction during the extrusion process, reducing the generation of surface flaws and defects. The inner wall of the square groove 67 is slidably connected with a slider 69, and the slider 69 is fixedly connected to the end of the bent plate 68 away from the square groove 67.

A spiral groove 643 is provided on the inner wall of the circular tube 641. The circular tube 641 penetrates the shell 21. When working, the circular tube 641 passes liquid, and the liquid moves toward the inside of the barrel 642 through the spiral groove 643 between the circular tube 641 and the rotating shaft 61, so that the liquid enters the inside of the barrel 642 and the circular tube 641 through the circular hole 644, and the liquid collides with the square plate 646, so that a shear force is generated inside the liquid, so that different parts of the liquid have a relative movement, the liquid is gradually dispersed, and the shear force in the liquid is reduced. The shear force will destroy the continuity of the liquid, thereby causing the liquid to disperse into fine water droplets, which are then ejected from the circular hole 644 to mix with the internal powder of the cylinder 22. The circular tube 641 rotates with the rotating shaft 61, so that the liquid is ejected evenly to avoid the powder and liquid not being able to fully contact and mix evenly. At the same time, it can also prevent the accumulation of too much and high powder, so that the powder at the bottom cannot fully contact with the liquid, which is prone to reduce the granulation efficiency. The spiral groove 643 is connected to the circular hole 644 on the circular tube 641. The circular tube 641 is fixedly connected to the outside of the cylinder 642 with an arc plate 645.

The discharge holes 26 are symmetrically arranged with the through hole 27 as the center. An extension plate 28 is fixedly connected to one side of the shell 21 near the feeding component 4, and the extension plate 28 is arranged at an angle.
[0022] The feed assembly 4 includes a feed hopper 41, which is fixedly connected to the top of the housing 21. A round rod 45 is fixedly connected to the inner wall of the feed hopper 41, and a V-shaped plate 44 is fixedly connected to the top of the round rod 45. In the initial state, the baffle 43 overlaps with the discharge hole 26. When powder is added to the inside of the feed hopper 41, the rotating shaft 61 drives the pressing plate 66 to rotate, and a collision occurs between the pressing plate 66 and the baffle 43. The baffle 43 is forced to move toward the direction of the round rod 45, so that the V-shaped plate 44 is deformed by force. Under the support force of the connecting plate 46, the sliding rod 47 moves upward inside the fixed frame 42, so that the baffle 43 on the other side moves toward the middle. , so that the powder falls into the interior of the cylinder 22 through the discharge hole 26 along the extension plate 28, so that the discharge amount of the powder can be adjusted according to the rotation speed of the rotating shaft 61, the outer side of the V-shaped plate 44 is fixedly connected with a baffle 43, the number of baffles 43 is two, the baffle 43 is an L-shaped plate, the baffle 43 is located inside the discharge hole 26, the V-shaped plate 44 is located inside the through hole 27, the inner wall of the feed hopper 41 is fixedly connected with a fixed frame 42, the inner wall of the fixed frame 42 is slidably connected with a slide rod 47, the outer side of the slide rod 47 is rotatably connected with a connecting plate 46, and the end of the connecting plate 46 away from the slide rod 47 is fixedly connected to the inner wall of the V-shaped plate 44.
[0023] A method for granulating powder of a plant extract comprises the following steps: S1. Powder is added, and the rotating shaft 61 drives the pressing plate 66 to rotate, so that the pressing plate 66 drives the baffle 43 to move, so that the powder falls into the interior of the cylinder 22 through the discharge hole 26 along the extension plate 28; S2, adding liquid, the circular tube 641 passes the liquid, the liquid moves toward the inside of the cylinder 642 through the spiral groove 643 between the circular tube 641 and the rotating shaft 61, and the liquid is sprayed out from the circular hole 644; S3, stirring and mixing, the rotating shaft 61 drives the straight rod 62 and the spiral plate 65 to rotate, and then the spiral plate 65 stirs the powder and the binder inside evenly, so that they are fully mixed, which helps to form particles with uniform structure; S4, forming particles. Under the action of the mutual attraction between the pressing plate 66 and the magnetic block 24, the magnetic block 24 moves, and the elastic plate 23 is stretched by force, so that the long strips extruded from the filter holes are cut off to form particles.
