[0061] A supporting leg 13 is provided at the bottom of the horizontal track B9.

[0062] When the present invention is used, the hydraulic cylinder A is first used to drive the ton bag holding clamp 5 to move backward to the maximum stroke. At this time, the spacing between the ton bag holding clamps 5 is greater than the width of the ton bag. The hydraulic motor drives the feeding plate 3 to rotate to the horizontal, and the ton bag holding clamp 5 is located below the feeding plate 3. The pneumatic rod B of the ton bag top rod 6 retreats into the pneumatic cylinder B to the maximum stroke. The hydraulic cylinder B14 drives the feeding plate 3 to move upward until the height difference between the end of the pneumatic rod B and the top surface of the ton bag turnover vehicle 8 is greater than the height of the ton bag. The pneumatic rod A extends out of the pneumatic cylinder A15 to the maximum stroke and drives the baffle 4 to close and seal the feeding through hole 24; then the ton bag turnover vehicle 8 moves along the horizontal track B9 to the outside of the ton bag feeding transposition. The open ton bag filled with materials is placed on the ton bag turnover vehicle 8; then the ton bag on the ton bag turnover vehicle 8 is moved along the horizontal track B9 to the bottom of the feeding plate 3 by the ton bag turnover vehicle 8; the feeding plate 3 is then driven downward by the hydraulic cylinder B14 until the pneumatic rod B of the ton bag top rod 6 below the feeding plate 3 is inserted into the material in the ton bag from the opening of the ton bag; the hydraulic cylinder B14 drives the feeding plate 3 to continue to move downward until the bottom surface of the feeding plate 3 is tightly fitted with the opening of the ton bag on the ton bag turnover vehicle 8; then the hydraulic cylinder A drives the ton bag clamping plate 5 to move toward each other and clamp the opposite sides of the ton bag; at this time, the pneumatic cylinder B drives the pneumatic rod B to overcome the friction resistance of the material in the ton bag and move downward Until the bottom of the ton bag is against the top surface of the ton bag turnover vehicle 8; then the hydraulic cylinder B14 drives the feeding plate 3 to move upward, so that the ton bag clamped between the ton bag clamping plates 5 is separated from the ton bag turnover vehicle 8, and the pneumatic rod B continues to overcome the friction resistance of the material in the ton bag and remains in an extended state under the drive of the pneumatic cylinder B, and props up the bottom of the ton bag downward; then the ton bag turnover vehicle 8 leaves the bottom of the feeding plate 3; then the hydraulic motor drives the feeding plate 3 to rotate 180 degrees around the hydraulic motor shaft, so that the feeding plate 3 and the ton bag clamped and fixed to the feeding plate 3 are turned over at the same time, so that the ton bag is located above the feeding plate 3 and the bag mouth of the ton bag is downward. At this time, the end of the pneumatic rod B continues to overcome the friction resistance of the material in the ton bag under the action of the pneumatic cylinder B.

When the feeding plate 3 moves downward to the maximum stroke, the pneumatic rod C extends out of the pneumatic cylinder C, so that the end frame contacts and presses with the feeding opening of the ton bag, and the dust cover forms a dust-proof passage to avoid dust during the feeding process; the pneumatic cylinder A15 drives the baffle 4 to move outward to the maximum stroke, so that the feeding through hole 24 can be fully opened, and the bag opening of the ton bag can be propped outward through the hook 31, thereby ensuring the bag opening flow of the ton bag, so that the material in the ton bag falls downward into the feeding opening of the ton bag through the feeding through hole 24;As the amount of material in the ton bag decreases, the frictional resistance of the material in the ton bag to the pneumatic rod B decreases, so that the pneumatic rod B continues to prop up the ton bag under the continuous action of the pneumatic cylinder B, and the ton bag holding plate 5 continues to move toward each other under the action of the hydraulic cylinder A, so that the ton bag is clamped by the ton bag holding plate 5, until the ton bag holding plate 5 moves toward each other to the maximum stroke under the action of the hydraulic cylinder A; when there is less material remaining in the ton bag, the residual material in the ton bag cannot automatically fall into the ton bag feeding port from the feeding hole 24, and the vibration device provided on the feeding plate 3 vibrates, so that the residual material in the ton bag continues to fall into the ton bag feeding port from the feeding hole 24; when the material in the ton bag is completely dropped into the ton bag feeding port, the power device B18 drives the roller A12 to drive the ton bag clamp to move along the horizontal track A11 to the top of the feeding plate 3, and then the pneumatic cylinder A15 drives the pneumatic rod A and the baffle 4 to move to the center of the feeding hole 24 to the maximum stroke, The feeding hole 24 is closed, and the hook 31 of the baffle 4 is separated from the bag mouth of the ton bag. At the same time, the pneumatic rod C retracts the pneumatic cylinder C to the maximum stroke, driving the end frame and the dust cover to move to the maximum stroke facing the feeding plate 3; then the hydraulic cylinder B drives the feeding plate 3 and the empty ton bag supported by the pneumatic rod A to move upward to the maximum stroke, at which time the ton bag supported by the pneumatic rod A is clamped by the ton bag clamping pliers; then the pneumatic cylinder A drives the pneumatic rod A to retract to the maximum stroke, and at the same time At this time, the hydraulic cylinder B drives the feeding plate 3 to move downward until the pneumatic rod A separates from the ton bag; then the power device B18 drives the roller A12 to drive the ton bag clamping tongs with empty ton bags to move along the horizontal track A11 to the empty ton bag collection area, and then the ton bag clamping tongs release the empty ton bags, so that the empty ton bags fall to the controlled ton bag collection area; after the feeding plate 3 separated from the empty ton bags leaves the top of the feeding plate 3, the hydraulic motor rotates the feeding plate 3 180 degrees in the opposite direction. ;

[0063] Then repeat the above steps to feed the next ton bag.
