[0015] The technical solution of the present utility model is further described in detail below through specific implementation methods. Example
[0016] like Figure 1-3As shown, the utility model provides a tobacco sheet sorting, weighing and metering device, comprising a screening box 1, a feeding port 2 is provided on the top of the screening box 1, a slag discharge port 3 is provided at the bottom of the screening box 1, a plurality of screens 4 are obliquely provided in the screening box 1, a discharge port 5 is provided at the lowest position of each screen 4 on the side wall of the screening box 1, and a vibrator 7 is provided on the side wall of the screening box 1; the feeding port 2 is arranged corresponding to the end of a first conveyor belt 6 for conveying tobacco sheets, and the discharge port 5 is arranged corresponding to the starting end of a second conveyor belt 9, and the end of the second conveyor belt 9 is cooperated with a weighing system 10; the weighing system 10 includes a storage bin 11 and a circulating conveyor belt 25; a discharge port 16 is provided at the bottom of the storage bin 11, and the discharge port 16 is connected to an inlet opened on the side wall of a conveying hose 12, one end of the conveying hose 12 is connected to the exhaust port of a fan 13, and the other end of the conveying hose 12 is connected to a temporary storage box 14 The top of the temporary storage box 14 is provided with an exhaust port 15; two supporting legs 22 are provided at the bottom of the temporary storage box 14, the bottom of the supporting legs 22 is provided with a footboard, and an annular support plate 21 is provided above the supporting legs 22, and a weighing sensor 20 is provided above the annular support plate 21. The bottom of the temporary storage box 14 is seated on the weighing sensor 20 through a plurality of support rods 19; a discharge port 16 is provided at the bottom of the temporary storage box 14, and a gate 17 is provided at the discharge port 16, one of the supporting legs 22 is provided with an electric push rod 18, and the telescopic end of the electric push rod 18 is connected to the gate 17; the circulating conveyor belt 25 is driven to rotate by a driving motor, and a plurality of trays 26 for supporting packaging boxes 27 are provided at equal intervals above the circulating conveyor belt 25; the vibrator 7, the fan 13, the electric push rod 18, the weighing sensor 20 and the driving motor are all electrically connected to the controller 28.
[0017] When the packaging box 27 runs to the bottom of the discharge port 5, in order to facilitate the control of the relevant equipment movement, a photoelectric sensor for the tray 26 is provided on the two supporting legs 22. The photoelectric sensor includes a transmitting device 23 and a receiving device 24 respectively arranged on the two supporting legs 22. The transmitting device 23 and the receiving device 24 are both electrically connected to the controller 28.
[0018] In order to prevent the smoke from overflowing from the exhaust port 15, a filter is provided at the exhaust port 15.
[0019] In order to facilitate the collection of tobacco residues, a collection box 8 is provided below the slag discharge port 3 of the screening box 1 .
[0020] The specific working principle of the present invention is as follows: the first conveyor belt 6 transports the tobacco slices to the feed port 2 and drops them into the screening box 1. Under the action of the vibrator 7, the tobacco slices are screened into different specifications, and then the tobacco slices are discharged from the discharge port 5 into the storage bin 11.
[0021] In addition, the controller 28 sets the weight of the tobacco slices tilted into the packaging box 27 each time, and the controller 28 sets the weight displayed by the weighing sensor 20 when the electric push rod 18 is opened. When setting the weight displayed by the weighing sensor 20, the influence of the wind pressure and the conveying hose 12 must be considered.
