The controller can calculate the number of tea leaves conveyed per unit time after calculating the acquired detection parameters, so as to provide more accurate basic parameters for subsequent processing and improve the processing quality of tea leaves.

[0023] The leaf leveling device 4 is installed at the lower horizontal section of the conveyor belt, and is used to disperse and mix the tea leaves on the lower horizontal section and form a tea layer of equal thickness, including a bracket 41 located on both sides of the conveyor belt and fixed on the frame, a bearing seat arranged on the bracket, a rotating shaft arranged on the bearing seat, a leaf leveling plate 42 fixed on the rotating shaft and spanning the lifting conveyor belt, and a leaf leveling motor driving the rotating shaft, wherein the bracket is a gate-shaped structure, a screw hole is processed on the top crossbeam of the bracket, and an adjusting screw 43 is screwed into the screw hole. A vertical slide groove is designed on the inner side of the columns on both sides of the bracket, and a slider 44 is embedded in the slide groove and can move up and down along the slide groove. The bearing seat is fixedly mounted on the slider, and the bottom end of the adjusting screw is fixedly connected to the top of the slider and drives the slider to move up and down. A positioning nut 45 is also installed on the adjusting screw and is fixed to the crossbeam through the positioning nut. The rotating shaft is mounted on the bearing seat, and the leaf leveling plate is mounted on the rotating shaft and rotates with the rotating shaft to break up and mix the fallen tea leaves. The leaf leveling motor is electrically connected to the controller and drives the rotating shaft to rotate;

[0024] The flake removal device 5 is installed behind the weighing device and is used for removing flakes and foam from the transported tea leaves. The flake removal device includes an air nozzle assembly installed on the frame and facing the outlet of the weighing belt, a longitudinal baffle 51 and an upper baffle 54 located below the weighing belt and dividing the tea leaf falling channel into front and rear halves, and an enclosure enclosing the bottom of the weighing belt. The air nozzle assembly is connected to an external air source and is electrically connected to a controller. The air nozzle assembly includes a plurality of nozzles 52 that are evenly distributed along the width direction of the weighing belt and match the width of the weighing belt. The upper edge of the longitudinal baffle is lower than the height of the nozzle, and the front of the longitudinal baffle facing the nozzle is enclosed by the enclosure to form a shape. The tea leaves are transported to a tea-leaf tea-leaf passage, a debris channel is formed on the back of the longitudinal baffle and a debris bag 53 is installed thereon, the upper baffle is located behind the longitudinal baffle, the bottom of the upper baffle is in an arc-shaped opening structure and opens toward the debris bag, the flake removing device adopts an airflow classification method, the airflow sprayed from the nozzle can blow the broken and light tea leaves to the back of the longitudinal baffle and be blocked by the upper baffle and the enclosure plate and collected by the debris bag, while the intact and heavier tea leaves fall vertically through the tea-leaf passage and are output, the tea leaves can be removed while being transported, thereby improving the quality of the tea leaves and correspondingly improving the accuracy of tea weighing.

[0025] The controller is used to control the above-mentioned conveying device and weighing device.

The tea leaves output from the outlet end of the previous process fall and accumulate on the lower horizontal section of the conveyor belt. At this time, the leaf leveling plate breaks up and mixes the tea leaves that have moved over, so that the thickness of the tea leaves in the lower horizontal section of the conveyor belt is kept within a certain range. Then, the vertical lifting plate of the conveyor belt lifting section catches the tea leaves and lifts them to the upper horizontal section. Due to the effect of vertical lifting, the number of tea leaves in each grid is basically the same and falls through the outlet of the upper horizontal section. The tea leaves on the weighing belt are transported to the weighing belt and then fall onto the weighing belt, forming an intermittent ridge-shaped stacking structure. At this time, the weight sensor under the weighing belt can detect the weight of multiple tea piles on the weighing belt in real time, and the metering roller can detect the moving speed of the weighing belt in real time. The above detection parameters are all transmitted to the controller. After calculation by the controller, the weight of the tea leaves transported by the conveyor belt can be timely counted to provide more accurate data for subsequent processing; the tea leaves on the weighing belt continue to move to the weighing belt outlet and fall down. At this time, the air flow belt sprayed by multiple nozzles blows the broken and light tea leaves in the falling tea leaves to the rear of the longitudinal baffle, and falls into the debris bag under the obstruction of the upper baffle, while the heavier intact tea leaves fall to another conveyor belt for delivery under the action of gravity.
