[0010] Preferably, material baffles are provided on both sides of the outlet of the hopper.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) The present invention provides a three-station material weighing machine, which has three weighing stations in the weighing bin. The three weighing stations can weigh materials at the same time. After the three weighing stations have finished weighing, the materials of the three weighing stations can be unloaded into the unloading hopper in sequence, which greatly improves the weighing efficiency.

[0013] (2) The present invention provides a three-station material weighing machine, wherein the bottom of the feed bin is provided with three feed ports, and the three feed ports are located directly below the three weighing bins, and can feed materials into the three weighing bins simultaneously or sequentially.

[0014] (3) The present invention provides a three-station material weighing machine with material baffles on both sides of the outlet of the hopper, and the material baffles on both sides will output the material in the hopper in a concentrated manner. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] A three-station material weighing machine includes a feed bin 1, a weighing bin 2, and a discharge hopper 3 arranged from top to bottom. Material is fed into the feed bin 1, weighed in the weighing bin 2, and then falls into the discharge hopper 3 for packaging. To concentrate the material in the discharge hopper 3, material baffles 4 are provided on both sides of the discharge hopper 3's outlet.

[0023] Three inlets 5 are located at the bottom of the feeding hopper 1. Insertion holes 6 are located on the side walls of the inlets 5, and opening doors 7 are located within the insertion holes 6. A servo motor 8 is connected to one side of the opening door 7, driving the opening door 7 to slide, thus opening and closing the inlets 5. A weighing platform 9 is located inside the weighing hopper 2, with both ends fixed to the interior of the weighing hopper 2. Three weighing stations 10 are located on the weighing platform 9, each directly below one of the three inlets 5. The three weighing stations 10 weigh the material falling from the three inlets 5. Weighing hoppers 17 are located at the top of each weighing station 10, corresponding directly below each inlet 5, and the material falling from the inlets 5 enters the weighing hoppers 17. Each weighing station 10 includes a weighing sensor 11 and a data acquisition module 12, which are integrated into the weighing station 10. After the weighing sensor 11 acquires data from the weighing hopper 17, it transmits the data to the data acquisition module 12 for aggregation. Further, the data acquisition module 12 transmits the data to the PLC module 13 connected to the weighing bin 2. A discharge port 14 is provided on one side of the weighing hopper 17, and a discharge gate 15 is hinged to the discharge port 14. A discharge motor 16 is provided at the discharge gate 15, controlling the opening and closing of the discharge gate 15. The discharge motor 16 is connected to and controlled by the PLC module 13. The PLC module 13 is connected to three servo motors 8, controlling the operation of the three servo motors 8.

[0024] The operator pours the material into hopper 1. PLC module 13 controls the opening door 7 to open, and the material enters three feeding hoppers 5. Weighing station 10 reads the weight data and transmits it to PLC module 13. After the material in feeding hopper 3 reaches the target weight, PLC module 13 controls the closing door 7. Further, PLC module 13 controls weighing hopper 17 to discharge material sequentially. After discharge, PLC module 13 controls the corresponding weighing station 10 to weigh the material, and the three weighing hoppers 17 discharge and weigh material in turn.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
