Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a high-shear wet granulator with uniform feeding, comprising an upper supporting platform 1, a supporting column 2 is fixedly connected to the lower surface of the upper supporting platform 1, a fixing ring 3 is fixedly connected to the one side surface of the supporting column 2, a lower supporting platform 4 is fixedly connected to the one side surface of the supporting column 2, a granulator housing 5 is fixedly connected to the upper surface of the lower supporting platform 4, a stirring scraper 6 is rotatably connected to the inner surface of the granulator housing 5, a cutting scraper 7 is fixedly connected to the one side surface of the granulator housing 5, an upper cover plate 8 is fixedly connected to the upper surface of the granulator housing 5, and a uniform feeding mechanism 9 is provided on the upper surface of the upper supporting platform 1;

[0022] The feeding mechanism 9 includes a feeding funnel 901, an electric push rod 902, an annular push rod 903, a conical disk 904, a material measuring cylinder 905, a steel ball 906, a uniform distribution bucket 907, a distribution hanging knife 908, a driven shaft 909, a driven gear 910, a driven turntable 911, a belt 912, a driving turntable 913, a driving gear 914, a driving shaft 915 and a motor 916. The upper surface of the upper support platform 1 is fixedly connected with the feeding funnel 901, the upper surface of the upper support platform 1 is fixedly connected with the electric push rod 902, the upper surface of the electric push rod 902 is fixedly connected with the annular push rod 903, the upper surface of the annular push rod 903 is fixedly connected with the conical disk 904, and one side surface of the feeding funnel 901 is fixedly connected with a material measuring cylinder The upper surface of the cylinder 905 and the feeding funnel 901 are slidably connected with a steel ball 906, and the upper surface of the steel ball 906 is slidably connected with a uniform distribution barrel 907. The inner surface of the uniform distribution barrel 907 is fixedly connected with a distribution hanging knife 908, and the upper surface of the distribution hanging knife 908 is fixedly connected with a driven shaft 909. One side surface of the uniform distribution barrel 907 is fixedly connected with a driven gear 910, and one side surface of the driven shaft 909 is fixedly connected with a driven turntable 911. One side surface of the driven turntable 911 is attached with a belt 912, and one side surface of the belt 912 is attached with a driving turntable 913. One side surface of the driven gear 910 is meshed with a driving gear 914, and one side surface of the driving gear 914 is fixedly connected with a driving shaft 915. A motor 916 is fixedly connected to the surface of one side of the rotating shaft 915. Through the setting of the feeding funnel 901, the electric push rod 902, the annular push rod 903, the conical disk 904, the material measuring cylinder 905, the steel ball 906, the uniform distribution barrel 907, the distribution hanging knife 908, the driven rotating shaft 909, the driven gear 910, the driven turntable 911, the belt 912, the driving turntable 913, the driving gear 914, the driving rotating shaft 915 and the motor 916, when in use, the material to be sheared is poured into the uniform distribution barrel 907, and then the motor 916 is started. The motor 916 drives the driving gear 914 and the driving rotating shaft 915 to rotate slowly, and the driving gear 914 and the driving rotating shaft 915 drive the driven gear 910 and the driven turntable 911 to rotate. Since the driving shaft 915 and the driving shaft 915 have the same size and the driven gear 910 is larger than the driving gear 914, when the motor 916 rotates, the angular velocity of the driving shaft 915 and the driving shaft 915 is the same, but the driven gear 910 is smaller than the linear velocity of the driven turntable 911, resulting in the speed of the loading funnel 901 being smaller than the speed of the distribution hanging knife 908. Therefore, when the uniform distribution barrel 907 and the material measuring cylinder 905 are aligned, the distribution hanging knife 908 will scrape the material into the material measuring cylinder 905. Then the material measuring cylinder 905 is filled, and the uniform distribution barrel 907 rotates to put the material measuring cylinder 905 in a closed space. Then the electric push rod 902 is started, and the electric push rod 902 moves downward to drive the conical disk 904 downward through the annular push rod 903.At this time, the material leaks out of the material measuring cylinder 905 and falls into the feeding funnel 901 and enters the granulator housing 5. Since the internal volume of the material measuring cylinder 905 is fixed, that is, the volume is the same each time it falls in, the uniformity of the material feeding and the stable feeding speed are achieved. The initial volume in the material measuring cylinder 905 can be changed by the height difference of the conical disk 904. Therefore, the volume of the material falling can be controlled by changing the pushing height of the electric push rod 902, which can control the uniformity of the material feeding and can achieve precise control.

[0023] Furthermore, multiple groups of support columns 2 are symmetrically arranged on the central axis of the support platform 1 above, and two groups of fixing rings 3 are arranged on one side of the support column 2. Through the arrangement of the support columns 2 and the fixing rings 3, when in use, multiple groups of support columns 2 are symmetrically arranged on the central axis of the support platform 1, so that the support platform 1 is evenly stressed and can effectively disperse the pressure from above, thereby ensuring the stability of the entire device during operation. Whether it bears the weight of the equipment or the vibration and impact force that may be generated during operation, it can remain stable, reducing equipment damage and production errors caused by shaking, and two groups of fixing rings 3 are arranged on one side of the support column 1, which further enhances the fixing effect on the connection part, prevents the connection part from loosening, and improves the reliability of the overall structure.

[0024] Furthermore, the electric push rod 902 is symmetrically arranged about the central axis of the upper feeding funnel 901, and the conical disk 904 is symmetrically arranged in six groups about the central axis of the annular push rod 903. Through the arrangement of the electric push rod 902 and the conical disk 904, when in use, the electric push rod 902 is symmetrically arranged about the central axis of the upper feeding funnel 901, ensuring that the force is evenly distributed in the process of pushing the annular push rod 903 and the conical disk 904. The conical disk 904 is symmetrically arranged in six groups about the central axis of the annular push rod, further enhancing the balance of the overall structure. This allows the material to fall into the feeding funnel more smoothly when it leaks out of the material measuring cylinder 905, avoiding tilting, shaking or blockage caused by uneven force, and ensuring the stable progress of the feeding process.

[0025] Furthermore, multiple groups of steel balls 906 are symmetrically arranged around the central axis of the feeding funnel 901, and six groups of distribution knives 908 are symmetrically arranged around the central axis of the uniform distribution barrel 907. Through the arrangement of the steel balls 906, when in use, multiple groups of symmetrically distributed steel balls 906 can make the feeding funnel more stable when in contact and relative motion with the uniform distribution barrel 907. The steel balls 906 play a role in reducing friction and providing support. The symmetrical arrangement ensures that the funnel is subjected to uniform force in all directions, and will not tilt or shift, thereby ensuring the smooth progress of the feeding process.

[0026] Furthermore, six groups of material measuring cylinders 905 are symmetrically arranged on the central axis of the upper feeding funnel 901. The feeding funnel 901 is connected to the uniform distribution barrel 907 through the steel ball 906, so that the uniform distribution barrel 907 can rotate freely. Through the setting of the material measuring cylinder 905, more materials can be processed per unit time during use, which greatly improves the feeding efficiency, can quickly distribute the materials to the granulator, reduces waiting time, and speeds up the production rhythm.

[0027] Furthermore, the outer dimension of the driven gear 910 is larger than the outer dimension of the driving gear 914, and the outer dimension of the driven turntable 911 is consistent with the outer dimension of the driving turntable 913. Through the setting of the driven gear 910, the driven turntable 911, the driving turntable 913 and the driving gear 914, when in use, the driving shaft 915 and the driving shaft 915 have the same size and the driven gear 910 is larger than the driving gear 914. When the motor 916 rotates, the angular velocity of the driving shaft 915 and the driving shaft 915 is the same, but the driven gear 910 is smaller than the linear velocity of the driven turntable 911, resulting in the speed of the loading funnel 901 being smaller than the speed of the distribution hanging knife 908, so when the uniform distribution barrel 907 and the material measuring cylinder 905 are aligned, the distribution scraper 908 will scrape the material into the material measuring cylinder 905.

[0028] Furthermore, the motor 916 is fixedly connected to the feeding funnel 901 below the evenly distributing barrel 907, and the active turntable 913 is fixedly connected to the active gear 914 through the active rotating shaft 915, and the two have the same angular velocity. Through the setting of the feeding funnel 901 and the motor 916, when in use, the motor 916 is fixedly connected to the feeding funnel 901 below the evenly distributing barrel 907, making the overall structure more compact. This layout saves space and facilitates the installation and maintenance of the equipment. At the same time, the compact structure also reduces the resistance of the material during the transmission process and improves the feeding efficiency.

[0029] Working principle: This is a high-shear wet granulator with uniform feeding. When the high-shear wet granulator needs to be evenly fed, the material to be sheared is poured into the uniform distribution barrel 907, and then the motor 916 is started. The motor 916 drives the driving gear 914 and the driving shaft 915 to rotate slowly. The driving gear 914 and the driving shaft 915 drive the rotation of the driven gear 910 and the driven turntable 911. Since the driving shaft 915 and the driving shaft 915 have the same size and the driven gear 910 is larger than the driving gear 914, when the motor 916 rotates, the angular velocity of the driving shaft 915 and the driving shaft 915 is the same, but the driven gear 910 is less than the linear velocity of the driven turntable 911, resulting in the speed of the feeding funnel 901 being less than the speed of the distribution hanging knife 908. Therefore, when the uniform distribution barrel 907 and the material measuring cylinder 905 are aligned, the distribution hanging knife 908 will scrape the material into the material measuring cylinder. 905, and then the material measuring cylinder 905 is filled, and the uniform distribution barrel 907 rotates to place the material measuring cylinder 905 in a closed space, and then the electric push rod 902 is started, and the electric push rod 902 moves downward and drives the conical disk 904 to move downward through the annular push rod 903. At this time, the material leaks out of the material measuring cylinder 905 and falls into the feeding funnel 901 and enters the granulator shell 5. Since the internal volume of the material measuring cylinder 905 is fixed, that is, the volume is the same each time it falls, the uniformity of feeding is achieved and the feeding speed is stable. The initial volume in the material measuring cylinder 905 can be changed by the height difference of the conical disk 904, so the volume of the material falling can be controlled by changing the pushing height of the electric push rod 902, so that the uniform amount of material fed can be controlled, and it can be precisely controlled. The model of the electric push rod 902 is YS-NZ100-12A, and the motor model 916 is WL-37RS528.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
