[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] refer to Figure 1-Figure 3 The double-station powder screw filling unit shown in the figure includes a base 1, one side of the base 1 is fixedly connected with a non-powered roller line 2 and a weighing belt conveyor line 3, and the other side of the base 1 is provided with a machine table 4, and the machine table 4 is provided with a lifting module 5 and a main powder filling machine 6 next to the non-powered roller line 2, and the machine table 4 is provided with an auxiliary powder filling machine 7 next to the weighing belt conveyor line 3. The main powder filling machine 6 is a large screw filling machine, which can quickly fill powder materials while reducing dust generation; the auxiliary powder filling machine 7 is a small screw filling machine. Filling, by cooperating with the weighing belt conveyor line 3 to carry out weighing feedback to replenish powder materials, the purpose is to slowly replenish and fill to improve the powder filling accuracy. A double-screw feeder 8 is arranged on the machine table 4 between the main powder filling machine 6 and the auxiliary powder filling machine 7. The double-screw feeder 8 can separately feed the main powder filling machine 6 and the auxiliary powder filling machine 7 through the forward and reverse rotation of the motor. The two discharge ports of the double-screw feeder 8 are respectively connected to the feed port of the main powder filling machine 6 and the feed port of the auxiliary powder filling machine 7 through conveying pipes.

[0016] The discharging end of the unpowered roller line 2 is butted against the feeding end of the weighing belt conveyor line 3 , and guardrails 9 are fixedly connected to both sides of the weighing belt conveyor line 3 .

[0017] A bracket 501 is fixedly connected to the moving platform of the lifting module 5 , and cylinders 502 are fixedly connected to both sides of the bracket 501 . A clamping claw 503 is fixedly connected to the sliding platform of each cylinder 502 .

[0018] A clearance groove is provided in the middle of the bracket 501 , and the discharge pipe of the main powder filling machine 6 is located in the clearance groove. Two cylinders 502 are arranged opposite to each other along the bracket 501 .

[0019] The working principle of the utility model is: manually put the packaging bag on the clamping claw, the cylinder 502 tightens the packaging bag mouth, the lifting module 5 drives the bracket 501 to rise and lift the packaging bag to the highest point, so that the discharge end of the main powder filling machine 6 is located at the bottom of the packaging bag (filling starts from the bottom of the packaging bag, which can greatly reduce the dust generated during the filling process), the main powder filling machine 6 is started, and pre-filling (about 95% of the predetermined total weight) begins, and then the lifting module 5 will drive the packaging bag to slowly descend during the filling process until the packaging bag is placed on the unpowered roller. After the cylinder 502 is unclamped, the pre-filled packaging bag is manually translated to the top of the weighing belt conveyor line 3, ready for secondary filling, and the weighing sensor in the weighing belt conveyor line is used to weigh in real time during the secondary filling, and the auxiliary filling machine head is controlled to perform accurate supplementary filling.

[0020] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific implementations.
