Background technique

At present, most carton processing enterprises on the market use manual carton forming machines or semi-automatic carton forming machines. Manual carton forming machines and semi-automatic carton forming machines need to manually open and fold the flat cartons that have been die-cut and printed on the feeding table. After the bottom, it is manually sent to the carton paste or nailing processing equipment for back sealing work. This type of carton processing equipment has defects such as low production efficiency, unstable quality, high labor cost, and high labor intensity; the above-mentioned manual carton processing equipment Most of the forming machines and semi-automatic carton forming machines can only seal the back of cartons with double-fold bottoms, but cannot seal the bottom of cartons with three-layer folded bottoms. Therefore, most cartons with three-layer folded bottoms are sealed manually. Double-layer folding bottom carton means that the two inner end pieces at the bottom of the carton are folded in half to form an inner layer, and the front cover and rear cover at the bottom of the carton are folded in half to form an outer layer, which is pasted on the left and right side walls of the carton with adhesive tape. Then paste the front cover and the back cover along the seams of the front cover and the back cover to complete the back cover; the three-layer folded bottom carton refers to the inner layer formed after the two inner end pieces at the bottom of the carton are folded in half. The front cover at the bottom of the carton is folded up to form the middle layer, and the rear cover at the bottom of the carton is folded up to form an outer layer on the front cover, so that the rear cover needs to be glued to the front side wall, left and right side walls of the carton with adhesive tape , The traditional carton forming machine cannot complete the side sealing work between the back cover and the front side wall of the carton.

The working principle of the utility model is as follows:

Fold the bottom first, and the bottom folding process is as follows: place the flat carton vertically on the feeding table, start the second rodless cylinder 14, and the second rodless cylinder 14 drives the second sliding plate 141 to drive the suction cup bracket 15 and the suction cup fixing plate 151 moves towards the direction of the feeding table until the suction cup 152 on the suction cup fixing plate 151 absorbs the flat carton on the feeding table, then the second rodless cylinder 14 drives the suction cup 152 and the flat carton sucked by the suction cup 152 to reset, In the reset process, the second cylinder 161 will drive the flap 16 to rotate backwards, and the flap 16 will act on the left side of the flat carton, and the flat carton will open after being subjected to the force. After the reset of the rodless cylinder 14 is completed, the first cylinder 132 drives the first folding bottom plate 131 to rotate upwards, and the first folding bottom plate 131 upwardly folds the inner end piece at the left bottom of the carton to the level, and then starts the first rodless cylinder 12, The first rodless cylinder 12 drives the first sliding plate 121 to move to the right, and the first sliding plate 121 drives the carton to move to the right. Fold the inner end piece on the bottom right side up until it is horizontal.

The first rodless cylinder 12 drives the carton to continue to move to the right in the conveying trough 26 in the second support 2, and the transmission belts 213 in the two side conveyor belts on the second support 2 are respectively in contact with the front and rear side walls of the carton , and transport the carton. At this time, the suction cup 152 no longer absorbs the carton, and the first sliding plate 121 resets to the left. During the movement of the carton to the right, the front cover at the bottom of the carton is in contact with the front flange guide round steel 18 , the front cover at the bottom of the carton is gradually folded upwards to the level along the guide round steel 18 of the front fold. During this process, the front cover at the bottom of the carton gradually covers the two inner end pieces. When the front flap at the bottom of the carton moves to the horizontal transition section 181 of the front flange guide round steel 18, the front flap at the bottom of the carton is completely wrapped on the two inner end pieces and folded to the level, and the rear flap at the bottom of the carton In contact with the rear flange guide round steel 19, the rear cover at the bottom of the carton gradually covers the front cover along the rear flange guide round steel 19 until it is folded horizontally.

When the right side wall of the carton hits the baffle plate 352, the carton will push the baffle plate 352 to drive the connecting plate 354 to overcome the second tension spring 357 and rotate clockwise until the baffle plate 352 is driven. The plate 352 is flush with the upper side wall of the mounting base 31, and the connecting plate 354 will drive the rotating shaft 35 to rotate clockwise when rotating, and the rotating shaft 35 will drive the serrated blade 351 to rotate clockwise when rotating, thereby making the serrated blade 351 avoid adhesive tape.

When the left side wall of the carton left the left swing arm 32, because the carton was also pressed against the right swing arm 33, the left swing arm 32 would not reset. Under the pulling force of the second extension spring 357, the rotating shaft 35 also resets counterclockwise along with the connecting disc 354 driving the sawtooth blade 351. The sawtooth blade 351 can cut off the tape when it comes into contact with the tape, and the carton moves to the right. When the auxiliary rubber wheel 331 on the right swing arm 33 is disengaged, the first tension spring 341 in the linkage mechanism drives the linkage plate 34 under the action of tension to drive the left swing arm 32 and the right swing arm 33 to reset together, and the right swing arm 33 is reset. During the process, continue to stick to the left side wall of the carton, stick the adhesive tape on the left side wall of the carton, when the left swing arm 32 meets the limit block 311, the left swing arm 32 and the right swing arm 33 stop moving . At this time, the adhesive tape is pasted on the left and right side walls of the carton and the rear cover at the bottom, and the adhesive tape stretches forward over the rear cover, the left side wall and the right side wall of the carton.

When the right side wall of the carton moves to the position corresponding to the first glue brush 4, the rotating cylinder 41 drives the first glue brush 4 to rotate backward to paste the adhesive tape protruding from the right side wall of the carton on the front side of the carton On the wall, when the left side wall of the carton moves to the position corresponding to the first glue brush 4, the rotating cylinder 41 drives the first glue brush 4 to rotate forward to paste the tape protruding from the left side wall of the carton on the carton. On the front side wall of the carton, when the carton moves to the right on the pallet 29, the push-pull cylinder 52 drives the biaxial lifting cylinder 54, the brush fixing plate 55 and the second glue brush 5 to move in the direction of the carton until the second glue The brush 5 is aligned up and down with the front side wall of the carton, and then the double-axis lifting cylinder 54 is started to drive the brush fixing plate 55 and the second adhesive brush 5 to move upward, and the second adhesive brush 5 sticks the adhesive tape protruding from the back cover On the front side wall of the carton, the push-pull cylinder 52 drives the third sliding plate 53 to drive the second glue brush 5 to reset forward, and the double-axis lifting cylinder 54 drives the second glue brush 5 to reset downward. This completes the back cover of the carton.
