As a preferred embodiment of the utility model, the device further comprises a toothed idler wheel, wherein the toothed idler wheel is arranged on the mounting plate, and the toothed idler wheel drives the synchronous belt to rotate.
In the specific embodiment of the utility model, the automatic powder discharging weighing module in the full-automatic coffee machine.
The weighing module of the coffee machine moves through a motor to finally control the left bin cover and the right bin cover to be closed, and the state is the initial state.
The coffee machine bean grinding module works, coffee beans are ground into powder and fall into the powder receiving cup cylinder, the coffee powder is fully paved layer by layer in the powder receiving cup cylinder and rises, the weight of the powder receiving cup cylinder is gradually increased at the moment, and the parallel beam weighing sensor uploads collected real-time weight data to the coffee machine control main board.
As shown in fig. 2, the parallel beam load cell 6 is a complete load cell, the aluminum surface is milled up and down, and the middle is hollowed out. The parallel beam load cell will detect the weight of the actual injected coffee grounds. The sensor is a load cell. The weighing sensor belongs to an independent module, the parallel beam weighing sensor 6 is connected with the supporting metal plate in a detachable mode, and the powder receiving cup cylinder is also detachable from the supporting metal plate. The right side of the parallel beam weighing sensor is fixed, and the left side is hung with all devices such as a powder receiving cup cylinder. The device utilizes the weight data transmitted by the parallel beam weighing sensor 6 to control the start and stop of grinding and the opening and closing of the bin cover.
When the set weight is reached, the coffee machine stops grinding, and the coffee powder does not fall down to the powder receiving cup cylinder. At this time, the weight of the coffee powder in the powder receiving cup cylinder is the required weight.
And after the required weight is achieved, the coffee machine controls the motor of the powder weighing module to rotate, so that the bin door is opened, and coffee powder with corresponding weight in the powder receiving cup cylinder is transferred to the next flow. After the device detects the set weight, the powder discharging device is opened in a linkage way.
The motor rotates anticlockwise, drives the motor synchronous pulley to rotate anticlockwise, and enables the left bin synchronous pulley 10 to rotate clockwise under the combined action of the motor synchronous pulley and the toothed idler pulley, and the right bin synchronous pulley 11 rotates anticlockwise. During rotation, the left and right synchronous pulleys 10 and 11 are always opposite and synchronous, so as to control the opening and closing of the left and right covers 2 and 3.
The left bin cover and the right bin cover are opened and closed synchronously and in a mirror image relationship, the whole structure is simple, occupied space is small, the synchronous belt and synchronous belt wheel structure is used, fine adjustment control is more accurate, motor torque is reduced, motor service life is prolonged, and noise in the whole motion process is low.
The concrete structure of the bin cover formed by the left bin cover and the right bin cover is as follows:
The bin cover adopts a ball bottom design, and can be connected with more coffee powder (in a shape of a reverse mountain bag) after the bin cover is closed. After the bin cover is opened, the modeling can enable the coffee powder to slide down towards the center when the coffee powder slides down, so that the coffee powder is accumulated in the center in the brewing cylinder to form a hill-pack shape, and the subsequent press cake extraction process is more facilitated.
The left bin cover and the right bin cover are designed to cover the bottom edge of the powder receiving cup cylinder by the top skirt after the left bin cover and the right bin cover are closed, so that powder leakage from the bottom edge of the powder receiving cup cylinder is prevented. The left bin cover bottom skirt edge structure is used for preventing powder leakage at the central joint after the left bin cover and the right bin cover are closed
The function of the powder through needle is to collide with the peripheral coffee powder along with the angle change in the opening and closing processes of the bin cover, so that the coffee powder in the bin cover is prevented from caking (the coffee powder is provided with grease) and is stuck on the powder receiving cylinder and does not fall. With the impact force in the process of quick opening and closing, the peripheral coffee powder is impacted by the angle change of the powder passing needle, so that the coffee powder is looser and is easy to slide.
