[0024] In a second aspect, the present application provides a waist sealing method, which adopts the following technical solution:

[0025] A waist sealing method, applied to the above-mentioned automatic waist sealing machine, comprises the following steps:

[0026] S1. A paper card is sucked away from the stack of paper cards and transported to the position where the adhesive protective paper is removed, the adhesive protective paper on the paper card is removed, and the paper card is transported to the position of the pallet located at the waist seal and positioned;

[0027] S2. The workpiece to be sealed is placed on the pallet, the upper pressing plate presses the workpiece, and at the same time, the paper card is pressed on one side of the pallet;

[0028] S3. The support plate and the upper pressing plate for pressing the workpiece are moved as a whole toward the side of the support plate pressing the paper card, and the end of the paper card is blocked away from the pressing side, so that the paper card is folded at the bottom of the support plate;

[0029] S4. Press the upper pressing plates on both sides of the workpiece waist seal position, and set folding guides at both ends of the paper card located at the waist seal position;

[0030] S5. Fold one end of the paper card on the pressing side onto the upper pressing plate, fold the end of the paper card away from the pressing side vertically, and then fold it horizontally onto one end of the pressing side;

[0031] S6. Apply pressure to the two ends of the folded paper card to seal it, so that one end of the adhesive surface of the paper card is bonded to the other end;

[0032] S7. The upper pressing plate is pulled out from the girdle-sealed workpiece, and the girdle-sealed workpiece is pushed away from the pallet in a direction perpendicular to the girdle;

[0033] S8. The support plate retreats from the sealing position to the workpiece loading position, and the upper pressing plate returns to the upper waiting position to wait for the next cycle of workpiece waist sealing.

[0034] By adopting the above technical scheme, the paper card is removed from the adhesive protective paper during the transportation process, and is positioned at the waist seal position of the pallet, thereby improving the efficiency of paper card transportation. The workpiece is pressed on the pallet by the upper pressure plate, and the paper card is also pressed on the pallet. By moving the pallet and blocking one end of the paper card, the paper card is folded on the bottom of the pallet, and the pallet is brought close to the paper folding station, thereby improving the work efficiency of paper folding. Pressing both sides of the waist seal position of the workpiece helps to prevent deformation of the upper pressure plate, and at the same time guides the paper folding at both ends of the paper card to prevent folding misalignment at both ends of the paper card, thereby improving the work quality of the waist seal. By applying pressure to both ends of the paper card for sealing, the firmness of the waist seal is improved. The upper pressure plate is pulled out from the sealed workpiece, which facilitates the quick unloading of the sealed workpiece from the pallet, thereby preventing damage to the sealed paper card during unloading, thereby improving the work efficiency and waist seal quality of the workpiece.

[0035] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] 1. The automatic waist seal machine loads paper cards through the loading device, presses the workpiece through the support plate and the upper pressing plate, and moves the workpiece close to the paper folding device under the translation of the translation device, so that the paper folding device can fold the paper card around the support plate and the upper pressing plate, and the folded paper card is pressed and sealed on the workpiece through the pressing device, which improves the reliability and quality of the waist seal of the workpiece, realizes the automatic waist seal of the workpiece, and improves the working efficiency of the waist seal;

[0037] 2. The paper card is pressed tightly on the support plate of the pallet, and the pallet is moved to a position close to the paper folding device through the translation frame, and at the same time, the end of the paper card away from the pressing is laid on the bottom of the pallet, which is convenient for the paper folding device to fold the two ends of the paper card, simplifying the paper folding process and improving the work efficiency of paper card folding;

[0038] 3. The clamping mechanism drives the clamping cylinder to move horizontally by disengaging the cylinder, so that the upper pressing plate on the clamping cylinder is located at the waist-sealing position or leaves the waist-sealing position. When the upper pressing plate is separated from the waist-sealed workpiece, it is convenient to separate the waist-sealed workpiece from the pallet, thereby improving the reliability of workpiece unloading. The clamping cylinder drives the upper pressing plate to clamp the workpiece, so that the workpiece in the clamping state is waist-sealed, which helps to improve the quality of the waist-sealing of the paper card on the workpiece;

[0039] 4. The translation frame is driven by the translation cylinder to move toward or away from the direction in which the pressing paperboard presses the paper card. When moving away from the direction in which the pressing paperboard presses the paper card, the paper card located in the paper card positioning slot is driven by the support plate and blocked by the inner wall of the paper card positioning slot and is flattened and folded under the support plate, so as to facilitate the subsequent folding of the two ends of the paper card;

[0040] 5. The second edge-sealing folding mechanism is installed in the folding installation groove, so that the translation frame drives the support plate to move toward the first edge-sealing folding mechanism. At the same time, the paper card folded on the bottom of the support plate is driven upward by the vertical driving cylinder, and the second edge-sealing folding paper board folds the paper card away from the support plate in a vertical direction. The second edge-sealing folding cylinder drives the end of the paper card away from the support plate to be pressed on the end close to the support plate, which helps to quickly complete the folding of the paper card and improve the work efficiency of folding paper.

[0041] 6. The sealing lifting cylinder drives the pressing parts to press the upper pressing plates on both sides of the waist seal position of the workpiece, which helps to prevent the upper pressing plates from deforming when pressing the workpiece. At the same time, the pressing parts guide the two ends of the paper card when folding, which helps to prevent the two ends of the paper card from being misaligned when folding. The sealing cylinder drives the sealing parts to apply pressure to the two ends of the folded paper card, so that the two ends are reliably bonded together, which helps to improve the quality of waist seal bonding;

[0042] 7. The de-sticking cylinder drives the de-sticking piece to contact the paper card position at the upper edge of the protective paper. The de-sticking lifting cylinder drives the de-sticking piece to move the protective paper downward, so that the protective paper is separated from the paper card, which helps to improve the automation of de-sticking and reduce the labor intensity of workers.

[0043] 8. The sealing method of the automatic sealing machine is as follows: the workpiece is pressed on the pallet by the upper pressing plate, the paper card is also pressed on the pallet, the pallet is moved and one end of the paper card is blocked, so that the paper card is folded on the bottom of the pallet, and the pallet is close to the paper folding station, which improves the efficiency of paper folding, and presses the two sides of the workpiece sealing position to help prevent the upper pressing plate from deforming. At the same time, the paper folding at both ends of the paper card is guided to prevent the folding and misalignment of the two ends of the paper card, thereby improving the working quality of the sealing, and the firmness of the sealing is improved by applying pressure to both ends of the paper card for sealing, and the upper pressing plate is pulled out from the sealed workpiece to facilitate the rapid unloading of the sealed workpiece from the pallet, thereby preventing damage to the sealed paper card during unloading, thereby improving the working efficiency and quality of the workpiece sealing.

[0068] S3. The pallet 42 and the upper pressing plate 431 pressing the workpiece are moved as a whole toward the side of the pallet 42 pressing the paper card 7, and the end of the paper card 7 is blocked away from the pressing side, so that the paper card 7 is folded at the bottom of the pallet 42;

[0069] S4. Press the upper pressing plate 431 on both sides of the workpiece waist seal position, and set the paper card 7 at both ends of the paper card 7 at the waist seal position to fold the guide;
