A polysilicon rod crushing and bagging machine

Abstract

The invention relates to a polycrystalline silicon bar material breaking and bagging machine. The polycrystalline silicon bar material breaking and bagging machine comprises a feeding device, a breaking device, a transfer and waste material removal device, screening devices, an automatic bag output device, a bagging device and weighing and packaging belt lines. The feeding device, the breaking device, the transfer and waste material removal device, the screening devices, the automatic bag output device, the bagging device and the weighing and packaging belt line are arranged in sequence according to the working procedure sequence. The automatic bag output device is located below the screening devices, and the bagging device is longitudinally arranged between the screening devices and the weighing and packaging belt lines. The weighing and packaging belt line comprises belt supporting tight press devices, sealing machines and discharging conveying frames. The belt supporting tight pressdevices are arranged in the mode of being close to one side of the bagging device. Each screening device comprises a screening frame, an upper screening layer, a lower screening layer and a second vibrating motor. Each belt supporting tight press device comprises a jacking mechanism, a transverse movement mechanism, a belt conveying device, a belt supporting and press mechanism and a weighing sensor. By the adoption of the polycrystalline silicon bar material breaking and bagging machine, full-automatic production from the working procedures of feeding, breakage and screening to the working procedures of weighing and packaging is achieved, the packaging production efficiency is improved, secondary pollution is avoided, the packaging quality is improved, manual participation is avoided, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of polysilicon production, in particular to a polysilicon rod crushing and bagging machine. Background technique [0002] After the polysilicon rods are crushed, they form bulk materials of uneven size and shape. The bulk materials need to be packed into inner and outer double-layer film bags according to the rated weight. The current packaging method is to manually pack the bulk materials Put it into the inner bag first, then place the material bag on the electronic platform scale for weighing, manually add or reduce the material according to the weighing result, when the material weight reaches the rated value, manually heat seal the bag mouth, and then manually The material bag is put into the outer bag, and finally the mouth of the outer bag is heat-sealed manually. [0003] The above method of manual packaging, manual bagging, bagging and weighing are troublesome, the labor intensity is high and the packaging ef...

Problems solved by technology

[0003] The above method of manual packaging, manual bagging, bagging and weighing are troublesome, the labor intensity is high and the packaging efficiency is low, the polysilicon is too sharp and easy to cut off the impurities on the gloves worn manually, resulting in polysilicon Secondary pollution in bagging affects the quality of bagged polysilicon
