A sealing device 17 is located between the second automatic weighing device 16 and the boxing zone 18 for sealing the silicon bin 13.

The boxing zone 18 is used for boxing the silicon bin 13 sealed by the sealing device 17 so as to facilitate the subsequent transportation of the silicon bin 13.

The automatic weighing device 19 is connected with the crusher 11, the automatic weighing device 19 is provided with four discharge ports 192, each discharge port 192 is provided with a quantitative feeding device (not shown in the figure), the four discharge ports 192 respectively correspond to the four weighing stations 191, and the discharge ports 192 can convey silicon materials from the crusher 11 to the position right above the silicon material box 13 through devices such as pipelines and add the silicon materials into the silicon material box 13 positioned at the weighing stations 191 from top to bottom.

The working principle of the adding and weighing production line is as follows:

the conveyor belt 141 is used for conveying the silicon material box 13 from the automatic bagging equipment 12 to the boxing area 18 for boxing;

after the polycrystalline silicon product is crushed by the crusher 11, the silicon material with the linear size of 5-50 mm is automatically loaded into the silicon material box 13 by the automatic bagging equipment 12, the silicon material box 13 is transported to the first automatic weighing equipment 15 by the conveyor belt 141 for weighing, the silicon material box 13 with the weight range of 9500-9800 g is transported to the adding and weighing station 191 by the conveyor belt 141, the silicon material box 13 sequentially passes through the four adding and weighing stations 191 and reaches the standard weight of 10000+/-5 g, the silicon material box 13 is transported to the second automatic weighing equipment 16 by the conveyor belt 141 for re-weighing, the silicon material box 13 meeting the standard weight is sealed by the sealing equipment 17, and then the silicon material box 13 is transported to the boxing area 18 by the conveyor belt 141 for boxing, so that the subsequent transportation of the silicon material box 13 is facilitated. As shown in fig. 2, the weights of the silicon materials added to the silicon material box 13 from left to right in the four adding and weighing stations 191 are respectively as follows: 30g (silicon linear dimension 30-50 mm), 20g (silicon linear dimension 10-20 mm), 10g (silicon linear dimension 5-10 mm) and 5g (silicon linear dimension 5mm or less). The number of the adding and weighing stations 191 can be appropriately increased or decreased, and the weight of each adding and weighing station 191 for adding silicon materials can be set according to the requirement.

From the above, the present embodiment reduces the manual use in the process of adding the scale, does not need to manually add the scale, improves the efficiency, avoids the condition of missing the scale, and reduces the non-silicon hidden trouble and the falling material existing in the process of manually adding the scale. In addition, four adding weighing stations 191 are provided in this embodiment, so that the accuracy of the weighed weight is guaranteed, for example, when the silicon material box 13 is weighed at the first automatic weighing device 15, the weight of the silicon material box 13 is different from the standard weight by 24g, a control system matched with the adding weighing production line can automatically identify the weight, the silicon material box 13 skips a 30g adding link (corresponding to a 30g silicon material adding station), the silicon material box 13 can firstly enter a 20g adding link (corresponding to a 20g silicon material adding station) to add 20g silicon material for 1 time, and then enter the next adding station (corresponding to a 5g silicon material adding station) to add 5g, so that the whole weight is only overweight by 1g, and the standard of 10000+ -5 g is met.

The existing adding weighing lines need 1-2 people to weigh each group, 3 groups are operated in turn every day, the average wages per person per month is 1 ten thousand yuan, 12 months a year, and the labor cost is as follows according to the calculation of one person of each adding weighing line: 1×3×10000×12=360000 yuan/year; in addition, when 3 teams of the existing addition weighing line are subjected to the shift-over, the floor material needs to be treated by sanitary cleaning, 1 person is added to each team for 30 minutes, 3 teams are added each day, and the time cost required by the sanitary cleaning for treating the floor material is calculated by 365 days a year: 1×30×3×365=32850 min/year.

The number of the added weighing production lines is 8 in this embodiment. Because the embodiment reduces the manual use and the generation of the floor material in the adding and weighing process, each adding and weighing production line provided by the embodiment theoretically reduces the labor cost by 36 ten thousand yuan/year, saves the time by 32850 minutes/year, realizes full automation of weight detection and adding and weighing actions, and obviously improves the production efficiency.
