In the embodiment of the present invention, the working principle is as follows:

s1: the bag opening component part:

s11: bag feeding station of the bag opening assembly: in the initial state, the upper bag opening cylinder and the lower bag opening cylinder are both in the extending positions, and after the packaging bag A11 is sleeved on the bag opening plate, the upper bag opening cylinder and the lower bag opening cylinder contract simultaneously to open the opening of the packaging bag.

S12: bag pushing station of the bag opening assembly: the bag opening is supported by the bag supporting component, and the bag opening is driven by the first driving component to move horizontally from the bag feeding station to the bag pushing station to wait for bag pushing.

S2: feed centering assembly part:

s21: feeding station of feeding centering assembly: the material is located first layer board and draws close through two pairs of middle baffle and to center and lead just, waits to push away the package.

S3: in the initial state, as shown in fig. 1, the bale pushing arm is located at the bale pushing origin. When the materials are ready on the feeding centering assembly, the wrapping arm is pushed forward under the guide of the centering guide plate.

S4: when the materials are about to go out of the feeding centering assembly, the correlation sensor detects for one time, if the packaging bag of the bag opening assembly is not in place, the packaging bag stays for waiting, if the packaging bag is carried in place (namely, the round hole is blocked, and the correlation vertical light path is not communicated), the bag pushing arm directly moves forward, and the materials enter the packaging bag through the two bag opening molds. When the materials completely fall into the packaging bags and continue to advance, the packaging bags are not clamped by the two bag supporting molds, the packaging bags and the materials are pushed forward to a heat sealing station by the bag pushing arms together, when the two pairs of middle clamping plates clamp the materials (with the material packaging bags) with the force adjusted in size, the materials are wrapped in a damping mode by means of friction force while the materials are straightened, and the moving speed of the bag pushing arms is reduced to a lower level. When the material and the packaging bag slowly move forwards, the bag opening of the packaging bag is gradually separated from the bag opening supporting die, when the round hole of the bag supporting die is exposed, the vertical light path is vertically and oppositely emitted, the bag opening position of the packaging bag is detected by the opposite-emitting sensor, the bag pushing motor starts to calculate pulses, the material is stably conveyed to a specified position according to a set value, and the expected length of the sealing margin (shown in figure 18) can be stably obtained at the position, so that the sealing margin of the packaging finished product is not influenced by the material dimension error and the packaging bag volume dimension error, and the sealing is neat and attractive.

S5: after the bag opening is detected, the bag opening component can be withdrawn in advance, the bag pushing arm is pushed to withdraw after the material reaches the end point, and the bag pushing arm retreats to the original point at full speed when the material is sealed, so that the next working flow is carried out. Then:

s51: bag arranging action of the bag arranging and heat sealing assembly: in the initial state, the upper and lower heat-sealing cylinders are in a retracted state, the upper and lower preformed bag arranging clamps are in an opened state, and the bags are cut left and right of the materials to be ready for being placed. The motion law of the bag arranging cutter is set by a servo motor, as shown in figures 12-15, after the heat-sealing material is in place, the air blowing pipe on the bag arranging cutter starts to blow air, and the bag arranging cutter is cut in the middle to be punched on the central line of the side face of the bag opening of the packaging bag, so that the organ bag forms a stable M-shaped edge. At the moment, the upper and lower preforming bag arranging clamps act, and the bag arranging cutter cuts further at the same time until the upper and lower preforming bag arranging clamps act completely, and the bag opening preforming is finished when only one slit is left for the bag arranging cutter to withdraw. In the whole bag arranging process, the bag opening is actually contacted with the bag arranging cutter and the bag arranging clamp, and the forming result is stable and reliable.

S52: and (3) heat sealing action of the bag tidying and heat sealing assembly: as shown in figures 16-17, after the bag mouth is preformed and the bag is arranged and cut out, the upper heat sealing plate moves in advance, the moving end point of the upper heat sealing plate is determined by the structure and is necessarily located on the center line of the bag clamp, and then the lower heat sealing plate moves to clamp the bag mouth and stay for a certain time to complete heat sealing. When the upper and lower heat-seal cylinders are selected, the thrust of the lower heat-seal cylinder is ensured to be smaller than that of the upper heat-seal cylinder, so that the cylinder diameter of the lower heat-seal cylinder is smaller, or the pressure is controlled by a pressure regulating valve.

Considering that two layers of packaging bag films are arranged in the middle part when the mouth of an organ packaging bag is folded, and 4 layers are arranged on two sides stacked by the M edge, air cylinders are arranged on two sides of the upper heat sealing plate and the lower heat sealing plate, so that the sealing stress is uniform, and the indentation depth is consistent. After the heat sealing is finished, the upper heat-sealing cylinder and the lower heat-sealing cylinder retract simultaneously, finished products are sent out, and the mechanism returns to the initial state.

The sealing height and the bag arranging height in the mechanism are always consistent due to structural constraint and are controlled by the sealing height adjusting motor in the figure 3, the bag arranging is controlled by the horizontal bag arranging servo motor, all power is electrically controlled, and the mechanism can be quickly and accurately adjusted by selecting a preset parameter combination when packaging specifications are switched, so that manual interference is not needed, and the mechanism is safe, efficient and convenient.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
