Among them, pre-weighing detection station 10 and rejection confirmation station 11 are provided with photoelectric switches corresponding to material conveying groove 1, and the photoelectric switches are arranged on both sides of material conveying groove 1. Since the installation space is small, the photoelectric switches are respectively installed at the upper end and the lower end of the material conveying groove, so that the position of the irradiation part on the material conveying groove 1 is consistent.

The strip bag cut by the strip bag machine is buffered by the buffer station 2, so that the pushing mechanism 8 pushes the material once, which matches the two cutting of the strip bag machine, so that the whole column weighing mechanism can match the running speed of the high-speed strip bag machine.

[0034] The sampling station 9 includes a conveying groove 1 and a sampling fence 29 and a sampling driving mechanism 30 arranged below the conveying groove 1 as shown in Figure 5 The sampling fence 29 includes a blocking part and a gap part, when no sampling is needed, the blocking part of the sampling fence 29 is below the conveying groove 1, and the blocking part constitutes the bottom of the conveying groove 1, so that the strip bag can smoothly pass through the sampling station, when sampling is needed, the sampling driving mechanism 30 drives the sampling fence 29 to move to one side, so that the gap part of the sampling fence 29 is aligned with the bottom of the conveying groove 1, and the strip bag falls to the output station below through the gap part, and is output through the conveying belt on the output station, all the two batches of strip bags are sampled through the sampling station 9, and according to the sampling result, it can be judged whether the strip bag formed by the strip bag machine is qualified.

[0035] After the strip bag passes through the sampling station 9, it enters the pre-weighing detection station 10, which detects whether the strip bag exists or not, if there is no strip bag in a conveying groove 1, the machine will be stopped and an alarm will be given.

[0036] As shown in Figure 6 The first weighing station 3 and the second weighing station 5 are respectively used for weighing the material on the odd number column conveying groove 1 and the even number column conveying groove 1, the rejection station 6 includes a first rejection station 15 and a second rejection station 16 arranged in sequence, a material conveying mechanism for outputting strip bags is arranged below the first rejection station 15 and the second rejection station 16, the first rejection station 15 is used for rejecting the unqualified material detected by the first weighing station 3, and the second rejection station 16 is used for rejecting the unqualified material detected by the second weighing station 5.
