DETAILED DESCRIPTION

[0033] As Figure 1 and 2As shown, a packaging device for long side folding of cigarette packet trademark paper, comprising a synchronous belt 201 conveying cigarette packets 1 from right to left, the front long side 101 of the trademark paper of the cigarette packet 1 is unfolded and located at the front side of the synchronous belt 201 and the rear long side 102 of the trademark paper is unfolded and located at the rear side of the synchronous belt 201, and a schematic view of the unfolded front long side 101 and the unfolded rear long side 102 of the trademark paper of the cigarette packet 1 is shown in Figure 8 The right part of the synchronous belt 201 is respectively provided with cold glue nozzles 301 at the front and rear sides, the left part of the synchronous belt 201 is respectively provided with hot glue nozzles 4 at the front and rear sides, the front and rear sides of the synchronous belt 201 at the left side of the hot glue nozzles 4 are respectively provided with first vertical push hands 501, the left rear side of the synchronous belt 201 is provided with a turntable 602 with a plurality of mold boxes 601, the two first vertical push hands 501 cooperate to push the cigarette packet 1 after glue spraying into the corresponding mold box 601 rotating above the synchronous belt 201, the two long sides of the trademark paper of the cigarette packet 1 in the mold box 601 are folded down in place, and the left side of the turntable 602 is provided with a vertical conveying channel, and the second vertical push hand 1201 below the vertical conveying channel pushes the qualified cigarette packet rotating in place into the vertical conveying channel.

[0034] In this way, after spraying cold glue and hot glue on the front long side 101 of the trademark paper of the cigarette packet 1 and spraying cold glue and hot glue on the rear long side 102 of the trademark paper of the cigarette packet 1, the two first vertical push hands 501 cooperate to push the cigarette packet 1 on the synchronous belt 201 upward into the mold box 601, which can fold the front long side 101 of the trademark paper of the cigarette packet 1 down in place and can fold the rear long side 102 of the trademark paper down in place, so that the front long side 101 of the trademark paper of the cigarette packet 1 and the rear long side 102 of the trademark paper are folded conveniently, and the front long side 101 of the trademark paper of the cigarette packet 1 is sprayed with cold glue and hot glue in sequence before folding, while the rear long side 102 of the trademark paper of the cigarette packet 1 is sprayed with cold glue and hot glue in sequence before folding, so that the front long side 101 of the trademark paper of the cigarette packet 1 and the rear long side 102 of the trademark paper have good bonding effect.

[0035] In one embodiment, as Figure 2As shown, a third vertical pusher 701 is provided directly above the synchronous belt 201 between the two first vertical pushers 501. The third vertical pusher 701 moves downward and is used to support the cigarette pack 1 pushed into the corresponding mold box 601. A fixed folding channel 8 is also provided directly above the synchronous belt 201. The fixed folding channel 8 is located directly below the third vertical pusher 701. The fixed folding channel 8 is used to fold the two long sides of the trademark paper of the cigarette pack 1 vertically lifted on the synchronous belt 201 downward into place. In this way, the two first vertical pushers 501 in front and behind cooperate to push the cigarette pack 1 on the synchronous belt 201 upward into the mold box 601, and at the same time the third vertical pusher 701 moves downward and resists the cigarette pack 1 pushed into the corresponding mold box 601. The third vertical pusher 701 can prevent the cigarette pack 1 pushed into the mold box 601 from continuing to move upward and detaching from the mold box 601. In the process of being pushed upward into the mold box 601, the cigarette pack 1 needs to pass through the fixed folding channel 8 first. After passing through the fixed folding channel 8, the front long side 101 and the rear long side 102 of the trademark paper of the cigarette pack 1 can be folded downward into place.

[0036] In one embodiment, Figure 2 As shown, there are eight mold boxes 601 and they are evenly distributed around the outer side of the turntable 602.

There is also an inspection station between the six o'clock station and the nine o'clock station. The inspection station is provided with a visual sensor for detecting whether the cigarette pack 1 after the front long side 101 and the rear long side 102 of the trademark paper are folded is a qualified cigarette pack or a defective cigarette pack. The fourth vertical pusher 901 is provided at the twelve o'clock station for pushing the defective cigarette pack in the mold box 601 conveyed to the twelve o'clock station downward into the waste bin 10, see Figure 3 The technology of using a visual sensor to detect whether the cigarette pack 1 after the front long side 101 and the rear long side 102 of the trademark paper are qualified or defective belongs to the prior art and will not be described in detail here. When the visual sensor detects that the cigarette pack 1 after the front long side 101 and the rear long side 102 of the trademark paper are qualified, the second vertical pusher 1201 pushes the qualified cigarette pack that has been rotated into place upward into the vertical conveying channel. When the visual sensor detects that the cigarette pack 1 after the front long side 101 and the rear long side 102 of the trademark paper are defective, the second vertical pusher 1201 does not move when the defective cigarette pack rotates to the nine o'clock position together with the mold box 601. When the defective cigarette pack rotates to the twelve o'clock position together with the mold box 601, the fourth vertical pusher 901 pushes the defective cigarette pack in the mold box 601 downward into the waste bin 10.
