A folding cover connecting rod 1534 is arranged on one side of the middle of the folding cover rotating shaft 1533, the folding cover connecting rod 1534 is connected with a folding cover pull rod 1535 consisting of a joint pin shaft arranged at the front end of the folding cover cylinder 1532, and the folding cover pull rod 1535 and the folding cover connecting rod 1534 can freely rotate within a certain angle range; the other side of the cover folding shaft 1533 is provided with a cover folding plate 1531, and the cover folding plate 1531 swings within a certain angle range along with the telescopic movement of the cover folding pull rod 1535 driven by the cover folding cylinder 1532.

After the box body 32 is fixed between the two cover fixing mechanisms 151, the guide is inserted into the lifting cylinder to descend, and the turnover cover 331 on the box body 32 is positioned between the guide seat 152 and the folding cover plate 1531; at this time, the cover-closing guide horizontal movement cylinder 1541 is in an extended state, and the front end surface of the guide base 152 is spaced from the front inner side of the box body 32 by a certain distance (0 to 5 mm). Since the box 32 is made of paper, the dimensional accuracy is not very high, and the front end of the guide 152 is kept at a certain distance from the inner side of the front surface of the box 32, so that the front end of the guide 152 can be more reliably inserted into the box 32 without interfering with the front surface of the box 32.

The closing guide horizontal movement cylinder 1541 retracts backward, so that the guide insert plate 1521d on the outer side of the front end of the guide base 152 is closely attached to the upper end of the inner plane of the front end of the box 32 (the front of the box 32 may be slightly bulged outward, so that the front end of the tongue 332 of the box 32, which is pre-folded, can be inserted into the box 32 more smoothly). At this time, the lid 331 of the box 32 is also bent by the folding plate 1531 by a small angle, the flap 332 at the upper end of the lid 331 is pre-folded by 90 °, but the elasticity of the material causes the flap to rebound, and if the angle of the flap 332 deviates from 90 ° greatly under abnormal conditions, 2 guide blocks 1524 installed inside the guide seat 152 will perform a corrective action. The cover folding cylinder 1532 retracts, the cover folding plate 1531 folds the cover 331, and the cover tongue 332 is inserted into the box 32 along the guide surface 1521 inside the guide seat 152.

At the initial stage of the guiding insertion of the lifting cylinder to rise, the flap 1531 keeps pressing the flap 331 of the box 32, because the flap 1531 is at the end of the stroke of the flap cylinder 1532 not retracting because of the resistance of the flap 331 of the box 32 and the product in the box 32. The flap cylinder 1532 is not retracted to the end of the stroke until the flap plate 1531 is separated from the flap 331 of the box 32 after the guide is inserted into the elevation cylinder to rise to a certain height. At this time, the lowest position of the front end of the folding plate 1531 is below the lowest position of the front end of the guide seat 152, that is, when the front end of the guide seat 152 is not completely pulled out from the box body 32, the folding plate 1531 always presses the flip 331, and the flip 331 is not taken out of the box body 32 due to the friction force generated when the guide seat 152 is lifted.

When the guiding insertion lifting cylinder rises to the top end, the cover fixing mechanism 151 retracts, the packaging box filled with the products 3 and folded by the turnover cover 331 flows downwards along the box conveying device 120, and when the packaging box reaches the position of the photoelectric sensor below, the control system enables all cylinders of the cover fixing device 150 to return to the initial position to prepare for the next cycle. At this time, if the specification containing device 170 has the case 32 containing the specification in the previous process, the specification containing device 170 will let the case 32 containing the specification go down to the present station, and perform the next operation of bending the lid 331.

step S2: the box transfer device 130 sucks the outermost folding plate 31 through the transfer sucking mechanism 142, and drives the folding plate 31 to leave the folding plate conveying device 110 through the transfer moving mechanism 141;

step S3: the box body transfer device 130 folds the folding plate 31 with a flat plate structure into a box body 32 with a three-dimensional structure through a folding device;

step S4: the cassette transfer device 130 puts the cassette 32 into the cassette conveying device 120 through the transfer moving mechanism 141;

step S5: loading the product 3 into the cassette 32 in the cassette conveyor 120 by the boxing unit 200;

Further, the folding device further includes a flap folding mechanism 164, the flap folding mechanism 164 is configured to fold a flap 332 of the upper cover 33, the box packing unit 200 of step S5 grabs the product 3 through the box packing grabbing mechanism 212, the box packing grabbing mechanism 212 lifts and moves the product 3 into the box body 32, and then the other side of the flip 331 opposite to the flap folding mechanism 164 blocks the flip 331 of the upper cover 33, and pushes the flap 332 of the upper cover 33 through the flap folding mechanism 164.

The packaging equipment has the characteristics of high working efficiency and small volume, and can effectively reduce the length in the transverse direction by respectively conveying the folding plate 31 with a flat plate structure and the box body 32 with a three-dimensional structure through the folding plate conveying device 110 and the box body conveying device 120 and arranging the folding plate conveying device 110 and the box body conveying device 120 in parallel. In addition, when the transfer suction mechanism 142 sucks the folding plate 31, the side wall folding mechanism 161 can fold the folding plate 31 out of the side wall of the box body 32, so that the folding box has the characteristics of high working efficiency, compact structure and small size. In addition, when the cover folding cylinder 1532 drives the cover folding plate 1531 to push the cover 331 to fold toward the top side of the box 32, the cover tongue 332 on the cover 331 is inserted into the box 32 along the guide surface 1521a, which has the characteristics of simple structure, low cost and high working efficiency.

In addition, because of the difference of the thickness and the strength of the paper materials of the paper boxes, a certain degree of waste phenomena can occur in the automatic packaging process of the paper boxes, such as the phenomenon that the paper boxes cannot reach the expected unfolded shape and the expected bearing strength after unfolding when being unfolded, or the phenomenon that the paper boxes cannot be completely closed when being closed, and the like, when the paper boxes are unfolded, the bottom wall pre-folding mechanism 162 and the cover tongue folding mechanism 164 are used for pre-folding, the problems that the expected unfolded shape and the expected bearing strength after unfolding can not be effectively achieved when being unfolded, the phenomenon that the paper boxes cannot be completely closed when being closed can be effectively overcome by the cover folding mechanism 153, and the purpose that the packaging rejection rate of the paper boxes is greatly reduced compared with the existing packaging equipment under the condition of the same paper box material is.
