Description

technical field [0001] The invention relates to the field of production of polysilicon particles, in particular to a fully automatic secondary counterweight packaging device for particulate matter and a counterweight packaging method thereof. Background technique [0002] With the rapid development of solar cells and solar power generation industries, the prospect of solar-grade polysilicon and the demand for market share are growing. In the process of polysilicon processing, polysilicon particles of various specifications need to be placed in PE packaging bags according to the set weight. in packaging. [0003] However, since polysilicon particles have various sizes, when carrying out bagging of larger-sized polysilicon particles, due to the large size of each polysilicon particle, its own weight is also large, and it is difficult to accurately obtain the standard weight of polysilicon particles by one weighing. Carry out bagging, because when the polysilicon particles on ...

[0003] However, since polysilicon particles have various sizes, when carrying out bagging of larger-sized polysilicon particles, due to the large size of each polysilicon particle, its own weight is also large, and it is difficult to accurately obtain the standard weight of polysilicon particles by one weighing. Carry out bagging, because when the polysilicon particles on the weighing equipment are close to the standard weight, if you continue to add polysilicon particles of the same size, once the number of added particles is too large, it is easy to exceed the standard weight, and if the quantity is too small, it will appear In the case of less than the standard weight, it is necessary to repeatedly adjust the number of polycrystalline particles to achieve the standard weight, which seriously affects the efficiency of weighing and bagging

[0004] Moreover, the existing weighing operation mainly relies on manually weighing the polysilicon particles to a standard weight through the weighing device, and then manually packing them into PE packaging bags for sealing, which is labor-intensive, low in automation, and low in efficiency.

[0005] At the same time, since polysilicon particles have different specifications, and polysilicon particles of each specification need to be packed in bags separately, when multiple polysilicon particles are bagged at the same time, different staff are required to process each specification of polysilicon Pellets are weighed and bagged, further increasing personnel costs

[0006] Finally, since manual operation inevitably comes into contact with polysilicon particles, this greatly increases the possibility of polysilicon particle contamination and reduces the quality of the product
