Automatic packing machine for polycrystalline silicon blocky bulk materials

Abstract

The invention discloses an automatic packing machine for polycrystalline silicon blocky bulk materials. The automatic packing machine comprises a bag feeding mechanism 1, a bagging mechanism 2, a material bag shaping mechanism 3 and a material bag sealing mechanism 4. The bagging mechanism 2 comprises a material falling cylinder 26 with a vertically lifting and dropping function. The bag feeding mechanism 1 comprises a bag clamping mechanism 13, the bag clamping mechanism 13 is located under the vertical axis of the material falling cylinder 26, the bag clamping mechanism 13 can support an opening of an empty bag to be a bag opening shape similar to the shape of the cross section of the material falling cylinder 26, and the material falling cylinder 26 can drop and be inserted in the bottom of the empty bag with the bag opening being supported. The material bag shaping mechanism 3 is located on the lower portion of the bag clamping mechanism 13 and comprises a horizontal moving frame 33; and a shaping mechanism 35 enabling the material bag to keep a preset shape is arranged on the horizontal moving frame 33. The material bag sealing mechanism 4 is located on the side of the bag clamping mechanism 13. The horizontal moving frame 33 can move the shaping mechanism 35 to be under the material bag sealing mechanism 4. Automatic bagging of the polycrystalline silicon blocky bulk materials is realized, and material pollution caused in the bagging process is avoided.

Description

technical field [0001] The invention discloses an automatic packaging machine for bulk polycrystalline silicon bulk materials, which belongs to the field of bulk material packaging equipment. 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. This manual packaging method has high labor intensity, low packaging efficiency, and great pollution to the...
