The working principle of the utility model is as follows:

firstly, bottom folding is carried out, and the bottom folding process comprises the following steps: the flat carton is vertically placed on a feeding table, the second rodless cylinder 14 is started, the second rodless cylinder 14 drives the second sliding plate 141 to drive the sucking disc support 15 and the sucking disc fixing plate 151 to move towards the direction of the feeding table until the sucking disc 152 on the sucking disc fixing plate 151 sucks the flat carton on the feeding table, then the second rodless cylinder 14 drives the sucking disc 152 and the flat carton sucked by the sucking disc 152 to reset, in the resetting process, the second cylinder 161 can drive the edge folding plate 16 to rotate backwards, the edge folding plate 16 acts on the left side edge of the flat carton, the flat carton can be opened after receiving the acting force, after the resetting of the second rodless cylinder 14 is completed, the first cylinder 132 drives the first folding bottom plate 131 to rotate upwards, the first folding bottom plate 131 upwards folds the inner end piece at the bottom at the left side of the carton to be horizontal, then the first rodless cylinder 12 is started, the first rodless cylinder 12 drives the first sliding plate 121 to move rightwards, the first sliding plate 121 drives the carton to move rightwards, the inner end piece at the bottom at the right side of the carton is in contact with the second folding bottom plate 17, and the second folding bottom plate 17 upwards folds the right side of the carton to be horizontal.

The first rodless cylinder 12 drives the carton to move to the right continuously to the conveying groove 26 in the second support 2, the transmission belts 213 in the two side conveying belts on the second support 2 are respectively contacted with the front side wall and the rear side wall of the carton, and the carton is conveyed, at the moment, the suction cups 152 do not adsorb the carton any more, and the first sliding plate 121 resets to the left, in the process of moving the carton to the right, the front cover sheet at the bottom of the carton is contacted with the front folding guide round steel 18, the front cover sheet at the bottom of the carton is gradually folded upwards to the horizontal along the front folding guide round steel 18, in the process, the front cover sheet at the bottom of the carton gradually covers the two inner end sheets, the carton continues to move to the right, when the front cover sheet at the bottom of the carton moves to the horizontal transition section 181 of the front folding guide round steel 18, the front cover sheet at the bottom of the carton is completely covered on the two inner end sheets and folded to the horizontal, and the rear cover sheet at the bottom of the carton is contacted with the rear cover sheet and the rear cover sheet of the rear folding guide round steel 19, at the bottom of the carton, and the rear cover sheet of the carton gradually covers the front side wall and the left and right side wall of the carton, and the left side wall of the right side wall of the carton, and right side of the carton are sealed by gluing of the carton.

The bottom sealing work flow is as follows: firstly, the mounting base 31 is moved forward through the sliding table 28, so that the main rubber wheel 321 and the auxiliary rubber wheel 331 in the mounting base 31 extend forward to the front side wall of the carton, the bottom of the carton is transited to the upper side wall of the mounting base 31 of the tape sealing machine core 3 from the rear folded edge guide round steel 19, at this time, the upper baffle plate 27 is arranged at the top of the carton in a blocking manner, the right side wall of the carton firstly collides against the main rubber wheel 321 of the left swing arm 32, the tape on the main rubber wheel 321 is adhered to the right side wall of the carton through the adhering surface, then the carton continues to move rightward, the carton pushes the left swing arm 32 to rotate clockwise until the main rubber wheel 321 on the left swing arm 32 and the upper side wall of the mounting base 31 are contacted with each other, the left swing arm 32 drives the right swing arm 33 to rotate counterclockwise under the action of the linkage mechanism, so that the auxiliary rubber wheel 331 on the right swing arm 33 is also flush with the upper side wall of the mounting base 31, when the right side wall of the carton collides against the baffle 352, the carton pushes the baffle plate 352 to drive the connecting disc 354 to rotate clockwise to overcome the second tension spring 357, until the baffle plate 351 and the upper side wall of the connecting disc 351 and the connecting disc 351 rotate clockwise, and the rotating shaft 354 drives the serrated blade 35 to rotate together when the rotating shaft 35 rotates clockwise, thereby driving the serrated blade to rotate together.

When the left side wall of the carton leaves the left swing arm 32, the carton is pressed against the right swing arm 33, so the left swing arm 32 cannot reset, when the carton leaves the baffle 352, the baffle 352 and the connecting disc 354 reset anticlockwise under the action of the tension of the second tension spring 357, the rotating shaft 35 also resets anticlockwise along with the connection disc 354 driving the serrated blade 351, the serrated blade 351 is contacted with the adhesive tape to cut off the adhesive tape when resetting, when the carton moves rightwards to be separated from the auxiliary rubber wheel 331 on the right swing arm 33, the first tension spring 341 in the linkage mechanism drives the linkage plate 34 to drive the left swing arm 32 and the right swing arm 33 to reset together under the action of the tension, the right swing arm 33 is continuously attached to the left side wall of the carton in the resetting process to attach the adhesive tape to the left side wall of the carton, and when the left swing arm 32 is connected with the limiting block 311, the left swing arm 32 and the right swing arm 33 stop acting. At this time, the adhesive tape is adhered to the left and right side walls and the rear cover plate at the bottom of the carton, and the adhesive tape extends forwards out of the rear cover plate, 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 adhesive brush 4, the rotary cylinder 41 drives the first adhesive brush 4 to rotate backwards to adhere the adhesive tape extending from the right side wall of the carton to the front side wall of the carton, when the left side wall of the carton moves to the position corresponding to the first adhesive brush 4, the rotary cylinder 41 drives the first adhesive brush 4 to rotate forwards to adhere the adhesive tape extending from the left side wall of the carton to the front side wall of the carton, when the carton moves to the right side to the supporting plate 29, the push-pull cylinder 52 drives the double-shaft lifting cylinder 54, the brush fixing plate 55 and the second adhesive brush 5 to move in the direction until the second adhesive brush 5 is aligned with the front side wall of the carton up and down, then the double-shaft lifting cylinder 54 is started to drive the brush fixing plate 55 and the second adhesive brush 5 to move upwards, the second adhesive brush 5 adheres the adhesive tape extending from the cover plate to the front side wall of the carton, then the push-pull cylinder 52 drives the third sliding plate 53 to drive the second adhesive brush 5 to move forwards, and the second adhesive brush 54 resets again. This completes the closing of the carton.

Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: modifications and equivalents of the embodiments of the invention may be made without departing from the spirit and scope of the invention, which should be construed as being covered by the claims.
