Example one

Referring to fig. 1, a coffee metering structure comprises a funnel 1 and a bean storage cylinder 2 for storing coffee beans, a cover body is arranged at the upper end of the bean storage cylinder 2, a weighing tray 3 is arranged between the funnel 1 and the bean storage cylinder 2, the bottom of the weighing tray 3 is fixedly connected with the funnel 1, the bottom of the bean storage cylinder 2 is embedded into the inner wall of the weighing tray 3, a guide piece 4 for guiding the coffee beans to a feeding channel 5 is arranged at the middle part of the bean storage cylinder 2, flow to the coffee beans and lead, locate in the unloading passageway 5 first 6 and the second of blockking and block 7, first 6 and the second of blockking block 7 and constitute a detention passageway 8 that can only hold a coffee beans, deposit a beans section of thick bamboo 2 and be connected with driving piece 9, driving piece 9 is connected with control structure, control mechanism control driving piece 9's output and then make first 6 and the second of blockking block 7 and release in proper order and open, guarantee that one of coffee beans falls down, control mechanism has the tally function.

Wherein, the first arch that blocks 6 for having elasticity, unloading passageway 5 comprises oblique ascending and vertical section, the second blocks 7 and is the oblique ascending section, the second blocks that the offside of 7 is equipped with drive gasbag 12, when coffee beans fall down, the second blocks 7 and the first coffee beans that can hold between 6 that blocks, after drive gasbag 12 aerifys, push through the first interception space that blocks 6 with a coffee beans, other backward extrusion ensures that a coffee beans is extruded at every turn, unloading passageway 5, the first 6 that blocks, the second blocks 7 and the structure that drive gasbag 12 constitutes and is equipped with the multiunit along depositing the bottom periphery of a beans section of thick bamboo 2, the beans efficiency under the assurance.

The driving part 9 is a turntable, the control mechanism comprises an air storage bag 10 and a driving protrusion 11, the air storage bag 10 is communicated with the driving air bag 12, the air storage bag 10 is internally provided with an elastic part to ensure that gas is mainly in the air storage bag 10, the driving protrusion 11 is arranged on the periphery of the driving part 9, and the driving protrusion 11 intermittently compresses the air storage bag 10 during the rotation time of the driving part 9 so as to enable the gas in the air storage bag 10 to be filled into the driving air bag 12.

Referring to fig. 2, the guiding member 4 is a cone located in the middle of the bean storage cylinder 2, guiding grooves are formed in the periphery of the bean storage cylinder 2, a triangular prism-shaped guiding block 13 is arranged between two adjacent guiding grooves, and the second blocking member 7 and the retention passage 8 are arranged in the guiding grooves to ensure that each coffee bean can fall into the guiding grooves and finally be guided out.

Example two

Referring to fig. 3, the difference from the embodiment is that the blanking channel 5 is a guide hole, the first barrier 6 and the second barrier 7 are both air bags, and the distance between the first barrier 6 and the second barrier 7 is larger than 1 time and smaller than 1.5 times the diameter of the coffee beans, so that the first barrier 6 is inevitably positioned lower than the center of the coffee beans above, pushes the coffee beans above upward when the coffee beans are inflated, and the second barrier 7 shrinks to release the coffee beans. Compared with example 1, example 2 has a faster blanking speed, but is also relatively complex.

Referring to fig. 4, the guiding members 4 are hexagonal frustum shapes coaxial with the discharging channel 5, and the guiding members 4 are formed into honeycomb shapes, so that the bottom of the bean storage cylinder 2 is provided with inclined planes, and the coffee beans are completely fallen and not left.

Referring to fig. 5, the driving member 9 is a piston cylinder driven by electromagnetism, and includes an electromagnet 91, a piston 92 with a magnet, and a cylinder 93, the electromagnet constantly changes direction to drive the cylinder 93 to move back and forth, two ends of the driving member 9 are respectively communicated with the first barrier 6 and the second barrier 7, so that the expansion of the first barrier 6 causes the contraction of the second barrier 7, and the expansion of the second barrier 7 causes the contraction of the first barrier 6.

The communication passage of the first barrier 6 is provided with a first electromagnetic valve 14, the communication passage of the second barrier 7 is provided with a second electromagnetic valve 15, when the first electromagnetic valve 14 and the second electromagnetic valve 15 are closed, only one group of corresponding first barrier 6 and second barrier 7 are communicated, and at the moment, one coffee bean falls down one by one, so that counting is convenient.

The working principle and the working process of the invention are as follows:

when the coffee bean storage device is used, the weight which accords with the taste of the coffee bean storage device is input, the controller predicts how many coffee beans are, the driving piece 9 drives the coffee beans to fall down, a set number of coffee beans fall down every time one cycle is driven, meanwhile, the weighing tray 3 weighs the whole coffee storage cylinder 2, the reduction amount of the total weight is calculated, after the coffee beans approach to the target number, the falling speed of the coffee beans is controlled, and the coffee beans stop falling after the reduction amount reaches the target weight.

In embodiment 1, the driving member 9 rotates to drop a specified number of coffee beans every time the driving member 9 rotates, when the driving member 9 rotates, the driving protrusions 11 extrude the air storage bags 10, the number of the driving protrusions 11 can be 1-6, the air storage bags 10 are extruded to expand the corresponding driving air bags 12, the coffee beans on the air storage bags are extruded to pass through the first barrier 6 and fall into the funnel 1 through the blanking channel 5 to be discharged, the coffee beans on the upper side cannot fall down due to the expansion of the driving air bags 12, and the technical accuracy of the coffee beans is ensured.

In embodiment 2, the electromagnet 91 drives the cylinder 93 to reciprocate, so that the first stopper 6 and the second stopper 7 are sequentially expanded, each one of the first stopper 6 and the second stopper 7 reciprocally drops a certain amount of coffee beans, the coffee beans above the first stopper 6 are stopped from dropping when the first stopper 6 expands, the second stopper 7 contracts to release the coffee beans in the staying channel 8, the coffee beans above the first stopper 6 contract to release the coffee beans, the second stopper 7 expands to stop the coffee beans in the staying channel 8, and when the target weight is approached, the first solenoid valve 14 and the second solenoid valve 15 are closed, so that only one coffee bean drops per reciprocation of the driving member 9.
