DETAILED DESCRIPTION

[0022] See Figures 1 to 6 As shown, a grinding device for producing solid coffee beverages includes a casing 1 and a grinding bucket 2 installed inside the casing 1. The casing 1 includes a body 3 and a top cover 4. The top cover 4 is fixed to the top of the body 3 by bolts. The separation of the body 3 and the top cover 4 facilitates the later maintenance of the equipment. The grinding bucket 2 is a funnel-shaped structure. A metal filter 5 is installed at the bottom of the grinding bucket 2. The metal filter 5 is installed to facilitate filtering of the ground coffee beans to prevent solid particles from being mixed in the coffee powder.

[0023] The metal filter 5 is connected to the grinding bucket 2 by a detachable connecting assembly. By making the metal filter 5 and the grinding bucket 2 detachable, it is convenient to subsequently disassemble, clean or replace the metal filter 5. The detachable connecting assembly includes a plurality of fixing blocks 18 and a plurality of locking nuts 19. The metal filter 5 is installed at the bottom of the grinding bucket 2. A limiting ring for limiting the metal filter 5 is installed on the bottom side wall of the grinding bucket 2. Each locking nut 19 is threadedly matched with the bottom thread of the grinding bucket 2. The fixing block 18 is threadedly matched with the locking nut 19. The fixing block 18 is installed at the bottom of the metal filter 5 through the locking nut 19. During the installation of the metal filter 5, the metal filter 5 is first inserted into the bottom of the grinding bucket 2, and the limiting ring is used to limit the top of the metal filter 5.

[0024] By rotating the fixing block 18 into the locking nut 19 in advance, the locking nut 19 will be assembled into the threaded hole that cooperates with the bottom of the grinding bucket 2, and the locking nut 19 will drive the fixing block 18 to gradually contact the bottom of the metal filter 5. When the locking nut 19 is rotated to the specified position, the fixing block 18 will be located at the bottom of the metal filter 5, thereby limiting the bottom of the metal filter 5.

[0025] A grinding roller 6 is also rotatably and slidably arranged inside the body 3, and the grinding roller 6 corresponds to the grinding hopper 2. A driving component 7 for driving the grinding roller 6 is arranged on the top cover 4. A discharge hopper 8 for feeding the inside of the body 3 is also installed on the top of the top cover 4. When grinding coffee beans, the driving component 7 will first lift the grinding roller 6 appropriately to facilitate the subsequent feeding and grinding of coffee beans, and the coffee beans enter the body 3 through the discharge hopper 8.

[0026] A sealing cover 21 is hinged on the top of the discharge hopper 8. When the coffee beans enter the discharge hopper 8, the sealing cover 21 will be closed to prevent external dust from entering the discharge hopper 8. A discharge pipe 22 is also installed in the top cover 4. The discharge pipe 22 corresponds to the grinding hopper 2. The coffee beans will pass through the discharge pipe 22 and enter between the grinding hopper 2 and the grinding roller 6 to facilitate subsequent grinding. The top of the grinding roller 6 is a conical barrel structure, and the bottom of the grinding roller 6 is an inverted cone structure. By designing the top of the grinding roller 6 into a conical structure, the coffee beans are prevented from falling to the top of the grinding roller 6 and being unable to be ground.

[0027] The driving assembly 7 includes a connecting rod 10, a hollow rod 11 and a cylinder 12. The connecting rod 10 is slidably arranged in the hollow rod 11. One end of the hollow rod 11 is rotatably arranged on the inner top of the top cover 4. One end of the connecting rod 10 passes through the hollow rod 11 and is fixed to the top of the grinding roller 6. The cylinder 12 is installed on the top of the top cover 4. The piston rod of the cylinder 12 passes through the top of the top cover 4 and is rotatably connected to the other end of the connecting rod 10. The rotational connection between the piston rod and the connecting rod 10 can be connected by a bearing. When it is necessary to drive the grinding roller 6 to rise and fall, the cylinder 12 can be started. The piston rod of the cylinder 12 will push the connecting rod 10 to slide in the hollow rod 11, and the grinding roller 6 is pushed to rise and fall through the connecting rod 10, thereby realizing the height adjustment of the grinding roller 6.

[0028] A driving motor 13 is also installed on the top of the top cover 4, and a driving component 2 14 for driving the hollow rod 11 to rotate is also provided inside the top cover 4. When the coffee beans have entered between the grinding roller 6 and the grinding bucket 2, the driving component 2 14 can be rotated by the driving motor 13, so that the hollow rod 11 is rotated, and then the connecting rod 10 is driven to rotate, thereby realizing the rotation of the grinding roller 6 to grind the coffee beans.

[0029] The driving component 2 14 includes a gear 15 and a gear 2 23. The gear 15 is fixed to the outside of the hollow rod 11. The output shaft of the driving motor 13 passes through the top wall of the top cover 4 and the gear 2 23 is fixed. The gears 15 and 23 are meshed with each other. The output shaft of the driving motor 13 drives the gear 2 23 to rotate. The rotation of the gear 2 23 drives the gear 15 on the other side that is meshed with the gear 15 to rotate. The rotation of the gear 15 and the gear 2 23 realizes the rotation of the hollow rod 11.

[0030] A plurality of slide grooves 16 are provided inside the hollow rod 11, and a plurality of slide bars 17 corresponding to the slide grooves 16 are fixed on the outer wall of the connecting rod 10. The hollow rod 11 limits the connecting rod 10 through the cooperation between the slide grooves 16 and the slide bars 17. The hollow rod 11 drives the slide bars 17 to rotate during the rotation process, and the slide bars 17 can drive the connecting rod 10 to rotate. The connecting rod 10 drives the grinding roller 6 to rotate, so that the coffee beans can be ground into powder. The cylinder 12 is also started during the rotation of the grinding roller 6. The connecting rod 10 drives the grinding roller 6 to rotate and at the same time drives the grinding roller 6 to gradually extend into the grinding bucket 2. The gap between the grinding roller 6 and the grinding bucket 2 will change from large to small, thereby realizing the gradual grinding of the coffee beans. When the coffee beans enter the grinding bucket, the minimum gap between the grinding roller 6 and the grinding bucket 2 is smaller than the coffee beans, thereby preventing the coffee beans from directly falling onto the metal filter 5 at the bottom and being unable to be ground. When the coffee beans are thoroughly ground, the cylinder 12 will pull the grinding roller 6 to lift, thereby ensuring that the coffee powder can completely fall onto the metal filter 5.

[0031] A scraper 20 is also installed at the bottom of the grinding roller 6. When the grinding roller 6 moves to a specified position, the scraper 20 at the bottom of the grinding roller 6 will come into contact with the metal filter 5. The rotation of the grinding roller 6 drives the scraper 20 to rotate, so that the scraper 20 can push the coffee powder on the metal filter 5, thereby facilitating the filtering of the coffee powder through the metal filter 5.

[0032] A material receiving frame 9 is also installed at the inner bottom of the body 3, and the material receiving frame 9 corresponds to the grinding bucket 2. The material receiving frame 9 is directly installed below the grinding bucket 2 so that the ground coffee powder can be directly received without the need for transmission, thereby reducing the waste of coffee powder. The side wall of the body 3 is an openable structure, and the structure can be opened by a sliding door. When a certain amount of coffee powder is received in the material receiving frame 9, the body 3 can be opened to take out and replace the material receiving frame 9.
