[0016] The beneficial effects of the present invention are:

[0017] 1. The driving motor drives two driven synchronous wheels to rotate through the active synchronous wheel and synchronous belt at the output end, so that the two driven synchronous wheels respectively drive the lower cutter discs of the two grinding mechanisms to rotate. The rotating lower cutter disc grinds the coffee beans between the lower cutter disc and the upper cutter disc into coffee powder. Thanks to the synchronous wheel and synchronous belt driving the two grinding mechanisms, it can play a buffering role during operation, maintain stability, reduce vibration and noise, and ensure the accuracy and stability of transmission.

Thanks to the simultaneous grinding of coffee powder of different coarseness and fineness, different types of coffee can be produced in a short time, which meets the diversified sales needs of coffee shops;

[0020] Fourth, the rotation angle of the adjustment gear is calculated by the calculated rotation angle of the worm shaft, and then the up and down movement amount of the movable mold assembly can be calculated by calculating the pitch of the movable mold assembly and the fixed mold assembly. These data are used to adjust the coarseness of the ground beans. Thanks to the setting of the control mechanism, the coarseness of the ground coffee powder can be accurately controlled;

[0021] 5. The O-ring increases the damping between the fixed mold seat and the movable mold ring. A shock-absorbing gasket is set between the fixed mold assembly and the movable mold assembly, which can effectively reduce the shaking of the movable mold caused by grinding beans and improve the stability when grinding coffee beans.

[0043] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0044] See also Figure 1-10A coffee bean grinding assembly for a fully automatic coffee machine includes a grinding platform 1, and the four corners of the grinding platform 1 are connected to a grinding base assembly 5 through rubber shock-absorbing pads 8. The grinding platform 1 is equipped with a driving motor 3, and the output shaft of the driving motor 3 is coaxially fixed with an active synchronous wheel 6. The grinding platform 1 is equipped with two sets of mirror-image grinding mechanisms 2, and the two sets of grinding mechanisms 2 are commonly plugged with a powder discharger 4, and the powder outlets of the two sets of grinding mechanisms 2 are connected to the powder discharger 4. The powder outlet of the grinding mechanism 2 is arranged on the side wall of the fixed mold base 231. The driving motor 3 is provided with a waist-shaped screw hole 31 and is connected to the grinding platform 1 by bolts. The waist-shaped screw hole 31 can conveniently adjust the front and rear distance of the driving motor 3, thereby adjusting the tightness of the synchronous belt 7. The use of rubber shock-absorbing pads 8 can reduce the inertial torsion caused by the instantaneous start of the driving motor 3, thereby ensuring the grinding stability.

[0045] The grinding mechanism 2 is provided with a fixed mold assembly 23 fixedly mounted on the grinding platform 1. A lower cutter disc 234 is rotatably arranged inside the fixed mold assembly 23, and a driven synchronous wheel 236 is coaxially fixedly connected below the lower cutter disc 234. A movable mold assembly 22 is threadedly connected to the top opening of the fixed mold assembly 23, and a motor adjustment assembly 21 for driving the movable mold assembly 22 to move up and down is installed on the fixed mold assembly 23. An upper cutter disc 225 that cooperates with the lower cutter disc 234 in parallel is coaxially fixedly installed at the bottom of the movable mold assembly 22. The motor adjustment assembly 21 drives the adjustment gear 222 to drive the movable mold assembly 22 to move up and down, thereby adjusting the distance between the upper and lower cutter discs. The two driven synchronous wheels 236 and the active synchronous wheel 6 are meshed with a synchronous belt 7. There are two left and right groups of grinding mechanisms 2, and two motor adjustment assemblies 21, which can adjust the coarseness of the ground beans separately to obtain coffee powder of different coarseness.

[0046] The driving motor 3 drives the grinding mechanism 2 through the synchronous wheel and the synchronous belt 7, which has the following two advantages: 1. Accurate and smooth transmission: The coordinated use of the synchronous wheel and the synchronous belt 7 can play a buffering role during operation, maintain stability, reduce vibration and noise, and ensure the accuracy and stability of transmission; 2. High efficiency and energy saving: The synchronous wheel transmission has a higher efficiency, can reduce transmission loss, and is easy to maintain. Only the synchronous belt 7 needs to be replaced, and compared with gear transmission, no grease is required, saving costs.

[0047] Each fixed mold assembly 23 includes: a fixed mold base 231 fixedly connected to the grinding platform 1. The fixed mold base 231 acts as a cavity and fixes the position of the lower cutter disc 234. The inner cavity of the fixed mold base 231 is rotatably mounted with a rotating shaft integrated bracket 232 through two bearings 233. The top of the rotating shaft integrated bracket 232 is coaxially fixedly assembled with the lower cutter disc 234, and the bottom of the rotating shaft integrated bracket 232 is connected to the driven synchronous wheel 236 through a coupling 235. The lower cutter disc 234 is directly mounted with the rotating shaft integrated bracket 232, and there is only one contact surface between the two, which can effectively ensure the flatness and ensure the coarseness of the coffee bean grinding, so that the coffee extraction time tends to be consistent and achieves a better flavor. The side wall of the fixed mold base 231 is provided with a plurality of raised fins, and a fan 237 is provided at the fins to cool down the heat generated by the ground beans in the fixed mold base 231, effectively avoiding the overheating of the cavity of the fixed mold base 231 causing the coffee powder to agglomerate and block the powder outlet.

[0048] Each movable mold assembly 22 includes: a movable mold ring 221 threadedly connected to the fixed mold assembly 23. The movable mold ring 221 is actually threadedly connected to the fixed mold seat 231. The bottom of the movable mold ring 221 is coaxially assembled with an upper cutter disc 225. The top of the movable mold ring 221 is assembled with an adjustment gear 222, and the adjustment gear 222 is a worm gear, which is used to adjust the up and down travel distance of the movable mold. A coaxial limiting half ring 223 is installed on the top of the adjusting gear 222, and the limiting half ring 223 is used to adjust the initial position of the upper cutter disc 225. The fixed mold assembly 23 is equipped with a motor adjustment assembly 21 that drives the adjustment gear 222. The motor adjustment assembly 21 is installed on one side of the fixed mold seat 231.

[0049] Each motor adjustment assembly 21 includes: a mounting frame 216 fixedly connected to the fixed mold assembly 23. The mounting frame 216 is fixedly installed on the top of the fixed mold seat 231. The mounting frame 216 is provided with a protrusion that cooperates with the column of the limiting semi-ring 223 to limit the initial position of the upper cutter disc 225. The mounting frame 216 is fixedly connected to the stepper motor 211 through the flange 212, and the output end of the stepper motor 211 is coaxially fixedly connected to the worm shaft 213 meshing with the adjustment gear 222. The mounting frame 216 is fixedly installed with a micro switch 215, and the worm shaft 213 is provided with annular evenly distributed protrusions, and the spring of the micro switch 215 is adapted to the annular protrusion of the worm shaft 213. When the protrusion of the spring is between the two protrusions of the worm shaft 213, the spring does not contact the worm shaft 213. The stepper motor 211 drives the worm shaft 213 to rotate, thereby driving the adjusting gear 222 to rotate, and the micro switch 215 is used to calculate the rotation angle and synchronously calculate the upper and lower distances of the movable mold assembly 22. A gasket 214 is sleeved on one end of the worm shaft 213 away from the stepper motor 211, and the gasket 214 is rotatably connected to the mounting bracket 216.

[0050] Specifically, five protrusions are provided at the place where the worm shaft 213 contacts the spring sheet of the micro switch 215. When the worm shaft 213 rotates, the protrusions lift the spring sheet, and the spring sheet then contacts the contact point of the micro switch 215, and the micro switch 215 receives a signal. When the micro switch 215 receives five signals, it means that the shaft rotates one circle. The rotation angle of the adjustment gear 222 is calculated by calculating the rotation angle of the worm shaft 213, and then the up and down movement amount of the movable mold assembly 22 is calculated by calculating the pitch of the matching between the movable mold assembly 22 and the fixed mold assembly 23. The coarseness adjustment control of the grinding beans is realized through these data.

[0051] A plurality of through holes of the fixed mold assembly 23 are respectively vertically slidably installed with an ejector pin 25 with a large head facing downward. A shock-absorbing gasket 24 is commonly clamped on the top of the plurality of ejector pins 25, and the shock-absorbing gasket 24 pushes the movable mold assembly 22 upward. A jackscrew 27 is threadedly connected to the bottom of the through hole of each fixed mold assembly 23, and a spring 26 in a compressed state is arranged between the jackscrew 27 and the coaxial ejector pin 25. The shock-absorbing gasket 24 is provided with a plurality of large holes and small holes connected together, the top of the ejector pin 25 can pass through the large hole, and the top annular groove of the ejector pin 25 can be inserted into the small hole. The fixed mold assembly 23 and the movable mold assembly 22 are elastically installed with the shock-absorbing gasket 24 to reduce the up and down vibration when grinding beans. The part of the movable mold assembly 22 extending into the inner cavity of the fixed mold assembly 23 is provided with an O-ring 224, and the O-ring 224 fits the inner cavity wall of the fixed mold assembly 23. The O-ring 224 increases the damping between the fixed mold seat 231 and the movable mold ring 221, fills the gap, and plays the role of sealing and preventing coffee powder from overflowing. A shock-absorbing gasket 24 is arranged between the fixed mold assembly 23 and the movable mold assembly 22, and the O-ring 224 is installed on the movable mold assembly 22, which can also effectively reduce the shaking of the movable mold caused by grinding beans and ensure the stability of the ground beans.

[0052] During the specific installation, the ejector pin 25 is placed in the preset through hole of the fixed mold seat 231, and then the spring 26 is placed, and finally the ejector screw 27 is screwed in so that the ejector pin 25 is in the position as shown in the figure. Figure 8 Position, that is, the uppermost position, at this time, the ejector pin 25 can be pressed downward, with a compression distance, and at the same time, the upper part of the ejector pin 25 is first passed through the large hole of the shock-absorbing gasket 24, and then the ejector pin 25 is rotated to the small hole adjacent to the large hole, so that the assembly is completed. At this time, the movable mold component 22 is in contact with the upper part of the shock-absorbing gasket 24. When the movable mold component 22 continues to move downward, the shock-absorbing gasket 24 is further compressed. At this time, the movable mold component 22 will receive the upward elastic force fed back by the spring 26, thereby achieving a shock-absorbing effect.

[0053] The grinding base assembly 5 is equipped with an integrated wiring harness plug 9, and the power plugs of the drive motor 3, the stepper motor 211, the fan 237, the micro switch 215, etc. are first quickly connected by the plug fixing seat 51 and then integrated with the wiring harness plug 9. The integrated wiring harness plug 9 is convenient for modular design and assembly, and multiple wiring harnesses can be quickly plugged and unplugged at the same time.

[0054] Working principle:

[0055] When in use, the two motor adjustment components 21 drive the movable mold component 22 to move up and down respectively, so as to adjust the distance between the lower cutter disc 234 and the upper cutter disc 225, so that the two grinding mechanisms 2 can grind coffee powder of different coarseness and fineness, wherein the driving motor 3 drives the two driven synchronous wheels 236 to rotate through the active synchronous wheel 6 and the synchronous belt 7 at the output end, so that the two driven synchronous wheels 236 respectively drive the lower cutter discs 234 of the two grinding mechanisms 2 to rotate, and the rotating lower cutter disc 234 grinds the coffee beans between the lower cutter disc 234 and the upper cutter disc 225 into coffee powder, and the coffee powder flows into the powder discharger 4 through the powder outlet of the fixed mold base 231;

[0056] When adjusting the distance between the lower blade disc 234 and the upper blade disc 225, the stepper motor 211 drives the worm shaft 213 to rotate, thereby driving the adjusting gear 222 to rotate, and the movable mold ring 221 rotates and moves relative to the fixed mold seat 231, so that the upper blade disc 225 installed at the bottom of the movable mold ring 221 moves to adjust the distance between the upper blade disc 225, and at the same time, the rotating worm shaft 213 protrudes and drives the micro switch 215 to switch continuously. When the micro switch 215 receives five signals, it means that the shaft rotates one circle. The rotation angle of the adjusting gear 222 is calculated by the calculated rotation angle of the worm shaft 213, and then the up and down movement amount of the movable mold assembly 22 is calculated by calculating the pitch of the movable mold assembly 22 and the fixed mold assembly 23. The coarseness adjustment control of the grinding beans is realized through these data.

[0057] It should be noted that the above content only illustrates the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications all fall within the protection scope of the claims of the present invention.
