After the bagging and sealing product is transported to the bag pinching opening position through the feeding part 1, the pushing block of the bag-supporting and pushing part 4 moves forward to push the material into the bag that is opened and constrained by the bag-supporting component 4-1; then, the pushing block of the bag-supporting and pushing part 4 retreats and exits the bag, and the upper and lower bag-supporting pieces of the bag-supporting component 4-1 move symmetrically to close, and the bag-supporting and pushing part 4 retreats and exits the bag as a whole; after completing pushing the material into the bag, the pinching The suction cup of the opening part of the bag opening part 3 cuts off the air to release the bag. At the same time, the bag pinching component 3-1 moves symmetrically to the left and right to pinch the bag in the sealed edge areas on both sides of the bag opening and flatten the bag opening. The bag clamping and transferring part 2-2 clamps the flattened bag that has completed feeding, and the bag opening is constrained by the product area to maintain its flattened state. Then the bag pinching component 3-1 releases the pinched bag opening, and the bag clamping and transferring part 2-2 then sends the unsealed product with the flattened bag opening to the pressing and sealing part 5 to be pressed, heated and sealed. The discharging part 6 transports the finished product that has been pressed, heated and sealed by the pressing and sealing part 5 to the outside of the machine, thereby finally realizing the fully automatic bagging and sealing operation of the product.
