Description
Technical Field
The invention relates to the technical field of cigarette packet automatic packaging equipment of cigarettes, in particular to the improvement of a forming wheel mechanism for folding and assisting heat sealing of transparent paper outside a small cigarette packet.
Background
The mechanism assembly of the transparent paper folding and forming wheel of the small cigarette packet is also called as a CH forming wheel, and the mechanism assembly is mainly used for completing the folding and forming of the transparent paper outside the small cigarette packet so as to facilitate the heat sealing of the long edge of the transparent paper by an iron. For cigarette packets, compared with cigarette cartons, the existing CH forming wheel has 6 stations, wherein 1-4 stations play a role in folding and forming, and the other two stations are empty stations. Through the folding of CH shaping wheel, the folding and the heat-seal of the long limit of the side have been accomplished to the packet cellophane, and the short edge folding of tobacco bale terminal surface is gone on in follow-up tobacco bale passageway.
The existing approximate process of folding and heat sealing of the CH forming wheel: the flat transparent paper is wrapped outside the small cigarette packet in a U shape, and in the process of pushing the flat transparent paper into a cigarette packet mold box of the forming wheel along with the small cigarette packet at a first station, the lower short edge 11 of the transparent paper impacts a mold box baffle plate of the CH forming wheel so as to be folded and reach the state shown in figure 17; then, under the action of the movement of a movable shovel plate matched with the lower part of the CH forming wheel, one long edge of the transparent paper is folded and attached to the small cigarette packet, and then the other long edge touches the edge of the circular arc plate above the CH forming wheel in the process that the CH forming wheel rotates clockwise to enter a second station, so that the transparent paper is folded and reaches the state shown in figure 18; at a second station, the hot iron bucket directly presses down the long edge of the transparent paper corresponding to the side surface of the small cigarette packet in the state shown in figure 18 to carry out primary heat sealing; performing secondary heat sealing by using another hot iron bucket at a third station; finally, at the fourth station, the small cigarette packet is pulled out of the cigarette packet mould box of the CH forming wheel by the cigarette packet hooking device, and in the movement process of pulling out the cigarette packet mould box, the upper short edge 12 of the transparent paper is contacted with the fixed folders at two sides of the channel, so that the cigarette packet is folded and formed.
The prior CH forming wheel has the technical defects that:
1. the folding precision of the arc plate is not high; the CH forming wheel adopts the circular arc board to carry out one of them long limit of capsule tobacco bale cellophane and folds, because the clearance between circular arc board and the CH forming wheel is about 2mm to can't carry out the accuracy and fold, lead to folding effect relatively poor. In addition, because there is great clearance between circular arc board and the CH shaping wheel, capsule tobacco bale side cellophane is in the unconfined state when ironing, at 2 nd station, the long limit cellophane of packet after folding lacks the constraint, capsule tobacco bale cellophane long limit is in the state of popping open, when the iron pushed down and ironed, the cellophane of popping open was contacted at first, the cellophane of popping open just has been scalded the wrinkle before compressing tightly the laminating, lead to capsule cellophane side heat seal effect not good, bubble and wrinkle appear easily, the influence leaves the factory the quality.
2. At the second station, when the hot iron directly presses down the long edge of the transparent paper corresponding to the side face of the cigarette packet in the state shown in fig. 18 for the first heat sealing, the upper short edge 12 and the long edge heat sealing surface of the transparent paper are both in the same plane, the upper short edge 12 is in a free state without stress, the iron easily scalds the upper short edge 12, and meanwhile, in the long edge heat sealing process, the adjacent upper short edge 12 is easily shrunk along with the long edge heat sealing surface, wrinkles are formed, the flatness of the subsequent upper short edge 12 after folding is influenced, the sealing effect is poor, and the quality is unsatisfactory.

A process for packaging transparent paper folding and forming wheel mechanism of small cigarette packet, which is characterized in that the process adopts the transparent paper folding and forming wheel mechanism of small cigarette packet as claimed in any one of claims 1 to 6, and the adopted process steps comprise:
(1) the smooth transparent paper is wrapped outside a small cigarette packet in a U shape and pushed into a cigarette packet mould box of a feeding station, the lower short edge of the transparent paper is impacted on a baffle plate and folded in the process of pushing the small cigarette packet into a cigarette packet mould box 4 of a feeding station 31, and two side edges connected with the front side and the rear side of the lower short edge of the transparent paper enter a transparent paper containing seam;
(2) one long edge of the transparent paper is folded and attached to the small cigarette packet by utilizing the motion action of the movable shovel plate, the transparent paper folding forming wheel mechanism of the small cigarette packet rotates clockwise, and the transparent paper and the small cigarette packet are folded by adopting the fixed long edge folding plate to block the other long strip in the process of entering a pre-folding heat-sealing station; when the sliding block slides at the pre-folding heat-sealing station, the left folder and the right folder are controlled to swing towards the direction close to the cigarette pack mould pack, the two long edges of the transparent paper are pressed and restrained by the left paper pressing claw and the right paper pressing claw, and the folding state is kept for heat sealing;
(3) the transparent paper and the small cigarette packet are rotated to a consolidation heat-sealing station, and a second heat sealing is carried out on the consolidation heat-sealing station by using a hot stamping bucket;
(4) the transparent paper and the small box tobacco bale after being consolidated and heat-sealed enter the discharging station, the transparent paper folding mechanism is opened under the control of the sliding block, the transparent paper and the small box tobacco bale are pulled out of the tobacco bale die box by the bale hooking device, the folder is fixed by the contact channel of the upper short edge in the process of pushing out the small box tobacco bale, and the folding of the short edge is completed.
7. The packaging process of the transparent paper folding and forming wheel mechanism of the small cigarette packet as claimed in claim 6, wherein the packaging process comprises the following steps: in the step (2), when the sliding block slides at the pre-folding heat-sealing station,
the baffle is synchronous to translate downwards, the second short edge folder synchronously rotates along with the slider to translate downwards, the paper pressing plate is turned to the position on the same plane with the baffle, the paper pressing plate is turned to the position above the upper short edge, and then the upper short edge of the transparent paper is folded downwards and restrained in the process of the synchronous downward translation of the paper pressing plate.
