Description

Technical Field

[0001] The present invention relates to the technical field of cigarette pack production equipment, and in particular to a device and method for adjusting the flatness of a small flat box of a cigarette pack. Background Art

[0002] Currently, there are two main types of materials used in cigarette packaging: transfer paper, which is gold and silver card material without a base film; and composite paper with a film. Composite paper undergoes printing, post-printing, and other processing steps before being die-cut into flat cigarette packaging boxes. These boxes can then be directly shipped to cigarette factories for packaging. Due to the special requirements of composite paper, which contains a film on its surface, the die-cutting process at the printing factory can easily cause the finished small boxes to warp. Cigarette packaging machines at cigarette factories require perfectly flat boxes, and warping is unacceptable. Deformation can directly cause malfunctions in the cigarette card packaging machines, severely impacting production efficiency.

[0003] The remedial measures of the existing production process are mainly: manually flattening the deformed and warped small box sheets, which is inefficient, difficult to operate, and prone to waste; or turning the deformed and warped small box sheets over and placing them on a paper pallet, and flattening them with heavy pressure. This method requires a long flattening time and the flattening effect is not obvious. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a device for adjusting the flatness of a small box of flat cigarette packs, including a machine base and a control system. The machine base is provided with at least one paper feeding track and a sliding track.

A fixing plate is connected to the sliding track. The lower side of the fixing plate is connected to a plurality of second driving members corresponding to the paper feeding tracks one by one. The driving end of the second driving member is connected to a first driving member located above the paper feeding track for adjusting the flatness of the small box of flat cigarette packs. The pressing paper plate on the paper feeding track is used to press the flat box of cigarette packs, and the upper side of the fixed plate is connected to the third driving member, and the driving end of the third driving member is connected to a mechanical arm for driving the mechanical arm to move up and down, and the arm head of the mechanical arm is connected to the fourth driving member, and the driving end of the fourth driving member is connected to a paper clamp for fixing and clamping the warped end of the flat box of cigarette packs, and the paper clamp is located on the right side of the machine base and drives the warped end of the flat box of cigarette packs to rotate clockwise and / or counterclockwise under the drive of the fourth driving member, and the control system is respectively connected to the first driving member, the second driving member, the third driving member, the fourth driving member and the paper clamp.

[0005] Preferably, vertical plates are respectively fixedly installed vertically on the front and rear sides of the machine base, and the sliding rails are horizontally arranged on the vertical plates.

[0012] S1. The control system controls the first driving member to start and drive the paper feed track to move the cigarette packs on the paper feed track to the right end of the paper feed track. At this time, the warped end of the cigarette packs is placed outside the paper feed track.

[0013] S2, the control system controls the first driving member to stop so as to pause the paper feeding track, and simultaneously controls the second driving member to drive the paper pressing plate to move downward, thereby pressing the flat cigarette packs on the paper feeding track;

[0024] In this embodiment, the first driving member, the second driving member, the third driving member and the fourth driving member are all driving motors, and the paper feeding track 11 is a conveying chain plate.

[0025] In this embodiment, the external cigarette pack flat box conveying mechanism places the warped cigarette pack flat box on the input end of the paper feeding track 11. Driven by the first driving member, the paper feeding track 11 conveys the warped cigarette pack flat box to the bottom of the paper pressing board 14. At this time, the warped end of the cigarette pack flat box is placed on the outside of the paper feeding track 11 (that is, the warped end of the cigarette pack flat box is located on the right side of the machine base 1).
