When the electric gate valve is opened, the weighted raw materials enter the second feeding hopper through the first discharge pipe and the oblique extension pipe. The raw materials entering the second feeding hopper enter the screw feeder. The screw feeder is used to conveniently transport the raw materials. The vibration motor is used to conveniently drive the three-screw feeder to vibrate, so that the mixing and conveying work of the batching device is carried out in a split manner. Therefore, it takes a long time to mix and convey after the proportioning is completed, which is not conducive to the production work.

[0008] Specifically, a second discharge pipe is provided at one end of the bottom of the screw feeder, and a second reserved opening corresponding to the second discharge pipe is penetrated and opened at one end of the top of the partition.

[0009] By adopting the above technical solution, the second reserved opening can prevent interference with the second discharge pipe when it vibrates to a certain extent.

[0024] A partition 17 is provided near the bottom of the inner wall of the box body 1, and a spring 14 is welded on the top of the partition 17. A second fixing column 15 is connected to the inner side of the spring 14, and a screw feeder 12 is connected to the top of the second fixing column 15. A second feeding hopper 21 is provided at one end of the top of the screw feeder 12, and a vibration motor 13 is fixed to one side of the screw feeder 12 by bolts. A second discharge pipe 19 is provided at one end of the bottom of the screw feeder 12, and the bottom ends of the oblique extension tubes 11 are located in the second feeding hopper 21.

[0025] When in use, the raw materials are weighted through two groups of feeding bins 4. When the electric gate valve 9 is opened, the weighted raw materials enter the second feeding hopper 21 through the first discharge pipe 8 and the oblique extension pipe 11. The raw materials entering the second feeding hopper 21 enter the screw feeder 12. The screw feeder 12 is used to conveniently transport the raw materials. The vibration motor 13 is used to conveniently drive the three-screw feeder 12 to vibrate, so that the mixing and conveying work of the batching device is carried out in a split manner. Therefore, it takes a long time to mix and convey after the proportioning is completed, which is not conducive to the production work.

[0026] For example, Figure 1 As shown, the utility model also includes that a second discharge pipe 19 is provided at one end of the bottom of the screw feeder 12 , and a second reserved opening 18 corresponding to the second discharge pipe 19 is penetrated and opened at one end of the top of the partition 17 .

[0028] For example, Figure 1 As shown, the utility model also includes that a third discharge pipe 20 is provided at one end of the bottom of the box body 1.

[0029] When in use, the third discharge pipe 20 facilitates the centralized discharge of the raw materials discharged from the second discharge pipe 19 .

[0030] For example, Figure 1 and Figure 2 As shown, the utility model also includes that vertical plates 22 are welded at both ends of the top of the box body 1, and a weighing instrument 16 is fixed to one end of the vertical plate 22 through a connecting rod, and the detection end of the weighing instrument 16 is located at the bottom of the fixed sleeve block 3.

[0031] When in use, the pressure on the bottom of the fixed sleeve block 3 can be conveniently detected by the weighing instrument 16 , thereby facilitating the weighing of the raw materials in the feeding bin 4 .

[0032] For example, Figure 1 As shown, the utility model also includes that first reserved openings 10 are penetrated through both ends of the top of the box body 1, and the electric gate valves 9 are located in the corresponding first reserved openings 10.

[0034] For example, Figure 1 As shown, the utility model also includes that a first feeding hopper 5 is arranged on the top of the feeding bin 4.

[0035] When in use, raw materials for MPPO production are conveniently added into the feeding bin 4 through the first feeding hopper 5 .

[0036] When the utility model is in use, raw materials for MPPO production are conveniently added to the feeding bin 4 through the first feeding hopper 5, and the weight of the raw materials in the feeding bin 4 is transmitted to the detection end located in the fixed sleeve 3 through the extension plate 6 and the fixed column 7. The pressure on the bottom of the fixed sleeve 3 is conveniently detected by the weighing instrument 16, and the signal of the weighing instrument 16 is connected to the external PLC, and the external PLC controls the opening and closing of the electric gate valve 9, so as to facilitate the weighing of the raw materials in the feeding bin 4;

[0037] The raw materials are weighted by two groups of feeding bins 4. When the electric gate valve 9 is opened, the weighted raw materials enter the second feeding hopper 21 through the first discharge pipe 8 and the oblique extension pipe 11. The raw materials entering the second feeding hopper 21 enter the screw feeder 12. The screw feeder 12 is used to conveniently transport the raw materials. The vibration motor 13 is used to conveniently drive the three-screw feeder 12 to vibrate, so that the mixing and conveying work of the batching device is carried out in a split manner. Therefore, it takes a long time to mix and convey after the proportioning is completed, which is not conducive to the production work.
