Background

Some products have sharp corners on the surface, and need to be bagged twice during packaging, so that the packaging is more reliable. For example, polysilicon products have sharp corners on the surface, and after primary bagging, the sharp corners easily puncture the bag, so secondary bagging is usually performed, and the polysilicon is wrapped firmly by two layers of packaging bags. When the conventional bagging equipment is used for secondary bagging, a product which is bagged (inner bag) and packaged at one time is usually directly filled into a second bag (outer bag), and then the outer bag is directly sealed. Because the bags for packaging products of heavy objects such as polysilicon and the like are usually thicker and harder, the bag openings of the inner bags after being packaged are vertical, and after the inner bags are directly arranged in the outer bags, the bag openings of the inner bags and the outer bags are overlapped together, which brings great difficulty to the packaging of the outer bags, the height of the outer bags is usually increased, so that the bag openings of the outer bags are higher than the bag openings of the inner bags to package the bag openings of the outer bags, which increases the height of the outer bags and causes the utilization rate of the outer bags to be reduced; meanwhile, as the bag opening of the inner bag and the bag opening of the outer bag are at the same side, when the bag opening is extruded by an internal product, the bag openings of the inner bag and the outer bag are easy to lose effectiveness, so that the product drops out, and the packaging stability is poor.

The bagging apparatus according to claim 7 wherein said inner side of said outer clamp is provided with a flexible cushion; the flexible cushion block is set to be an inflatable cushion block, a gas storage cavity is arranged in the inflatable cushion block, a plurality of joints for inflating and deflating the gas storage cavity are arranged on the side face of the inflatable cushion block, and the inflatable cushion block is arranged on the inner side face of the limiting flange on the outer clamping plate.

9. The bagging device as recited in claim 1, wherein the outer bag positioning mechanism comprises a lifting support, a guide channel arranged on the lifting support, and a bag opening positioning assembly arranged on the lower side of the lifting support, the lifting support is arranged at a third position and can be vertically lifted, the bag opening positioning assembly comprises two outer pressing plates which are vertically distributed in parallel, and two movable plates which are arranged between the two outer pressing plates and can move in a direction perpendicular to the outer pressing plates, and a bag clamping gap is formed between the movable plates and the outer pressing plates; when the outer bag after being opened moves to the third position, the lifting support descends to enable two sides of the long edge of the bag opening of the outer bag to respectively enter the bag clamping gap, the outer press plate moves inwards, the movable plate moves outwards, and the bag opening of the outer bag is located in an opening state.

10. The bagging apparatus as defined in claim 9 wherein the two outer pressing plates are disposed to move toward and away from each other in a direction perpendicular to the movable plates, and the lower side of the lifting frame is provided with a shaping plate disposed between the two movable plates and movable in a direction parallel to the outer pressing plates; when the inner bag falls into the outer bag at the third position, the two outer press plates and the movable plate are close to each other, so that the opening of the outer bag is closed, and the shaping plate moves inwards to press the middle part of the short edge of the bag opening of the outer bag downwards to finish shaping of the M-shaped bag opening.
