when the paper bag 7 is sealed, a worker or a manipulator places the paper bag 7 on the conveyor belt 21, then a controller on the sealing equipment controls the conveyor belt 21 to run so that the paper bag 7 reaches the position where the glue coating block 61 is positioned, at the moment, the controller controls the conveyor belt 21 to pause and starts the electric push rod III 6 so that the glue coating block 61 moves towards the opening of the paper bag 7 and is inserted into the opening of the paper bag 7, then the controller controls an external glue pump to convey glue to the glue outlet 612 through the glue pipe 611 and is coated on the inner wall of the opening of the paper bag 7, then the controller controls the electric push rod III 6 to retract so that the glue coating block 61 is withdrawn from the opening of the paper bag 7, then the controller controls the conveyor belt 21 to continue to run, the paper tape after the glue coating is moved to the position below the pressing plate 5 is stopped, at the moment, the controller controls the electric push rod III 41 and the electric push rod III to run so that the glue coating block 422 moves upwards and the pressing plate 5 moves downwards to squeeze the opening of the paper bag 7, then the controller controls the heating block 423 to work, glue is adhered to the opening of the paper bag 7, then the electric push rod III is retracted to retract to enable the electric push rod III to retract from the opening of the paper bag 7, and the paper bag 7 to be continuously sealed by the sealing equipment after the electric push rod III is continuously retracted to the position of the paper bag 21 and the paper bag 7 is continuously sealed;
meanwhile, as the pressing blocks 53 are arranged on the pressing plate 5, when the pressing plate 5 moves downwards and the supporting plate 422 moves upwards, the pressing blocks 53 positioned at the middle position of the pressing plate 5 are firstly contacted with the paper bags 7, and the pressing blocks 53 positioned at the two ends of the pressing plate 5 are contacted with the paper bags 7, so that the pressing blocks 53 are contacted and extruded from the middle position of the opening of the paper bags 7 towards the two ends, glue smeared on the inner wall of the opening of the paper bags 7 is extruded and flattened, and the glue on the inner wall of the opening of the paper bags 7 is uniformly distributed and fills the inner wall of the opening;
when the pressing block 53 contacts and presses the paper bag 7, the baffle 521 also contacts and presses the paper bag 7, a certain strip-shaped area is formed in the paper tape opening, the length direction of the area is perpendicular to the opening direction of the paper bag 7, and then the area is used for limiting and intercepting glue on the inner wall of the paper tape opening, so that the glue on the inner wall of the paper bag 7 opening is pressed by the pressing block 53, and when the glue moves along the opening direction of the paper bag 7, the glue is blocked by the baffle 521 and cannot overflow out of the paper bag 7 or move towards the inside of the paper bag 7;
by arranging the interception groove 522 on the baffle 521, the excessive glue is overflowed after being pressed, after the glue passes through the area formed by the flange 523 on the baffle 521 and the paper bag 7, the glue enters the area where the interception groove 522 is positioned, the baffle 521 does not contact the paper bag 7 in the area where the interception groove 522 is positioned, and no resistance effect exists on the overflowed glue, so that the pressure born by the overflowed glue is released in the area where the interception groove 522 is positioned, the glue is gathered and buffered in the area where the interception groove 522 is positioned, and the glue is prevented from continuing to be subjected to the excessive pressure effect and passing through the pressing edge 524 on the baffle 521;
when the glue on the inner wall of the opening of the paper bag 7 is blocked, and the glue enters the area where the interception groove 522 is located, the heat of the glue heated by the heating block 423 is easily dissipated by the heat dissipation plate 525, so that the solidification and bonding speed of the glue near the pressing edge 524 are increased;
by setting the height of the baffle 521 outside the pressing plate 5 to be larger than the height of the pressing block 53 outside the pressing plate 5, the baffle 521 can firstly contact and press the paper bag 7, and a closed area is formed inside the paper tape opening by pressing the paper bag 7 through the baffle 521 to block glue;
when the paper bag 7 is glued, along with the action of the electric push rod III 6, the suction plate 62 firstly reaches the area where the paper bag 7 is located, then under the action of high-speed air flow blown out from the air flow hole 622, a certain suction effect is generated on the paper bag 7 according to the Bernoulli principle due to the fact that the distance between the suction plate 62 and the paper bag 7 is relatively short, so that the opening of the paper bag 7 is unfolded, the glue can smoothly extend into the opening of the paper bag 7 together with the gluing block 61, and meanwhile, the glue on the gluing block 61 is sprayed onto the inner wall of the paper bag 7 in a pulse mode, so that the glue is impacted and attached to the inner wall of the paper bag 7, and the contact between the glue and the gluing block 61 is reduced;
through seting up constant head tank 22 on conveyer belt 21 to make the mesh seting up inside constant head tank 22, thereby the suction plate 62 that distributes in rubberizing piece 61 upper and lower both sides can produce the suction effect to the upper and lower both sides face of the opening part of container bag 7, thereby make container bag 7 opening part expansion as far as possible, in conveniently rubberizing piece 61 stretches into container bag 7, simultaneously, constant head tank 22 and silica gel point mutually support, improve the position stability of container bag 7 on conveyer belt 21.
