[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-6 This utility model provides a technical solution: a rice flour grinding device for preventing accumulation, including a shell 1, a support frame 2, a first grinding disc 3, a flow guide frame 4, a second grinding disc 5, an electric drive grinding ring 6, a first moving frame 7, an electric drive slide rail 8, a second moving frame 9, a cleaning frame 10, a sealing cover 11, a feeding hopper 12, a spiral flow guide plate 13, a limiting block 14, and a material equalization plate 15;
[0033] Among them, the shell 1 is the outer shell of the grinding equipment. The bottom opening of the shell 1 is connected to the support frame 2 via a short connection. A grinding disc 3 is placed on the upper end of the support frame 2, and a grinding disc 5 is installed on the upper end of the grinding disc 3. The grinding disc 3 and the grinding disc 5 constitute one of the main structures for grinding rice flour.
[0034] The structure of grinding disc 3 matches the shape of the inner wall at the bottom of the shell 1. Grinding disc 3 is set as a ring structure. A flow guide 4 is installed in the center of grinding disc 3. Grinding disc 5 and the surface of grinding disc 3 abut against the surface of electric drive grinding ring 6 to form a grinding structure. The motor end of electric drive grinding ring 6 is installed in moving frame 7. The surface of grinding disc 3 is set as inclined. Grinding disc 3 and electric drive grinding ring 6 are installed at an inclined angle. Electric drive grinding ring 6 abuts against the inclined surface of the side wall of grinding disc 5. An inverted T-shaped opening is provided in the support frame 2. The opening of the support frame 2 is connected to the opening at the bottom of the flow guide 4. The flow guide 4 is set as a Y-shaped pipe. A column penetrating grinding disc 5 is provided at the upper end of the flow guide 4. A grid structure abutting against the surface of grinding disc 3 is provided at the bottom of grinding disc 5. The grid gap at the bottom of grinding disc 5 is connected to the Y-shaped pipe in the flow guide 4.
[0035] Referring to the attached diagrams in the instruction manual Figures 1-6As shown, assemble the housing 1 and support frame 2. During use, place the support frame 2 on a stable working surface or above the conveyor belt, ensuring its stability. Then, insert the grinding disc 3 from above the housing 1, installing the housing 1 and grinding disc 3 together. Next, install the flow guide frame 4 at the center of the grinding disc 3, and then install the second grinding disc 5 onto the upper part of the flow guide frame 4. Figures 2-4 As shown, when the grid at the bottom of the second grinding disc 5 abuts against the surface of the first grinding disc 3, the first grinding disc 3 and the second grinding disc 5 work together with the electric-driven grinding ring 6 to grind the rice flour raw material. The electric-driven grinding ring 6 grinds the raw material on the surfaces of the first grinding disc 3 and the second grinding disc 5. The ground rice flour rolls along the inclined angle of the first grinding disc 3, enters the diversion frame 4 through the grid at the bottom of the second grinding disc 5, and is discharged from the opening of the support frame 2. This ensures smooth discharge without blockage. If there is poor discharge or uneven grinding, the rotation speed of the electric-driven grinding ring 6, the sliding speed of the moving frame, or the feed amount of the raw material can be adjusted appropriately. During use, the wear of easily worn parts such as the first grinding disc 3, the second grinding disc 5, the electric-driven grinding ring 6, and the cleaning frame 10 should be checked regularly. If severe wear is found, they should be replaced in time to ensure the grinding effect and anti-accumulation performance of the equipment.
[0036] The first movable frame 7 is slidably connected to the electric drive slide rail 8, which is installed on the inner wall of the housing 1. The second movable frame 9 is also slidably connected to the electric drive slide rail 8. An inclined cleaning frame 10 is installed inside the second movable frame 9, and the cleaning frame 10 abuts against the surfaces of the second grinding disc 5 and the first grinding disc 3. The inclination angle of the cleaning frame 10 matches the inclination of the surfaces of the first grinding disc 3 and the second grinding disc 5. A sealing cover 11 is installed at the opening at the upper end of the housing 1, and the sealing cover 11 is installed with the feed hopper 12. The bottom end of the sealing cover 11 is... The feed hopper 12 is provided with a sliding groove that slides with the first movable frame 7 and the second movable frame 9. The inner wall of the feed hopper 12 is provided with a spiral guide plate 13, and the spiral guide plate 13 abuts against the limiting block 14. The feed hopper 12 and the limiting block 14 are fitted together and installed. The distance between the limiting block 14 and the feed hopper 12 gradually decreases from top to bottom. The bottom end of the limiting block 14 abuts against the top column of the guide frame 4. The bottom end of the limiting block 14 is provided with a material equalization plate 15, and the material equalization plate 15 is provided above the second grinding disc 5. The surface of the material equalization plate 15 is provided with a strip-shaped opening.
[0037] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, during use, the motor end of the electric drive grinding ring 6 is installed inside the movable frame 7, and then the movable frame 7 is installed on the electric drive slide rail 8 on the inner wall of the housing 1, ensuring that the movable frame 7 can slide smoothly on the electric drive slide rail 8. Similarly, the movable frame 9, which is equipped with the sweeping frame 10, is simultaneously installed on the electric drive slide rail 8, ensuring that it slides normally, and that the sweeping frame 10 abuts against the surfaces of the grinding discs 3 and 5, with the tilt angle matching the tilt of the grinding disc surface. Figures 2-4As shown, during use, the first movable frame 7 and the second movable frame 9 rotate synchronously at the same speed, so that the electric-driven grinding ring 6 and the cleaning frame 10 are set at 180°. During use, the surface of the first grinding disc 3 is inclined and has an inclined angle with the electric-driven grinding ring 6. The electric-driven grinding ring 6 also synchronously abuts against the inclined surface of the side wall of the second grinding disc 5, so that the raw material can be better squeezed and ground during the grinding process. At the same time, a certain flow trend is formed on the surface of the grinding disc, reducing accumulation. The cleaning frame 10 is used to clean the rice flour that may accumulate on the surface of the grinding disc and push it to a suitable position for further grinding or into the discharge channel. The ground rice flour can pass through the grid at the bottom of the second grinding disc 5. The rice flour enters through the Y-shaped pipe in the feed rack 4 through the gaps in the grid, and then exits through the inverted T-shaped opening in the support frame 2. The smooth discharge channel design also helps prevent rice flour accumulation. During use, a small amount of rice flour raw material is slowly added from the feed hopper 12. Observe whether the raw material enters the grinding area evenly under the action of the spiral feed plate 13, the limiting block 14, and the equalizing plate 15. At the same time, observe the grinding process of the electric-driven grinding ring 6 on the rice flour, and check whether the grinding fit between the first grinding disc 3, the second grinding disc 5, and the electric-driven grinding ring 6 is good. Since the distance between the limiting block 14 and the feed hopper 12 gradually decreases from top to bottom, it plays a preliminary role in limiting and guiding the flow. The raw material finally passes through the strip-shaped opening of the equalizing plate 15 and is evenly sprinkled above the second grinding disc 5 for rice flour grinding.
[0038] Working Principle: When using this anti-accumulation rice flour grinding equipment, the rice flour raw material enters the equipment from the feed hopper 12. The spiral guide plate 13 on the inner wall of the feed hopper 12 guides the raw material to spiral down along the hopper wall, preventing the raw material from accumulating at the feed inlet. As the distance between the limiting block 14 and the feed hopper 12 gradually decreases from top to bottom, it plays a preliminary role in limiting and guiding the flow. The raw material finally passes through the strip-shaped opening of the equalizing plate 15 and is evenly sprinkled above the second grinding disc 5. The rice flour raw material on the second grinding disc 5 is ground by the electric drive grinding ring 6 sliding on the electric drive slide rail 8, interacting with the surfaces of the first grinding disc 3, the second grinding disc 5, and the electric drive grinding ring 6. During use, the cleaning frame 10 slides on the electric drive slide rail 8 with the moving frame 2 9 to clean the grinding disc in a timely manner. Rice flour that may accumulate on the surface is pushed to a suitable position for further grinding or into the discharge channel. The first moving frame 7 and the second moving frame 9 slide on the electric drive slide rail 8. The two work together to ensure the effective grinding and cleaning action. The sealing cover 11 provides a sealing effect, and the sliding groove at its bottom provides guidance and support for the sliding of the first moving frame 7 and the second moving frame 9. The diversion frame 4 in the center of the first grinding disc 3 and the grid structure at the bottom of the second grinding disc 5 work together. The ground rice flour can enter the Y-shaped pipe in the diversion frame 4 through the grid gap at the bottom of the second grinding disc 5, and then be discharged from the inverted T-shaped opening in the support frame 2. The smooth discharge channel design also helps to prevent rice flour accumulation and increases the overall practicality.
[0039] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
