[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] See also Figure 1-2 The present invention provides a technical solution: a laminating device for packaging printing, wherein a plurality of rectangular grooves 1.1 extending transversely and longitudinally are provided in the middle of the top surface of a base 1; the ends of the central axis of a drive roller 2 are rotatably sleeved onto the two side walls of the inner cavity of the rectangular groove 1.1, and a drive mechanism is provided on the side wall of the base 1 for driving the drive rollers 2 to rotate synchronously. The end of the central axis of the drive roller 2 passes through the side wall of the base 1 and is fixedly sleeved with a pulley 2.1. The pulleys 2.1 on the same side are connected to a transmission belt 3 for common transmission. A side frame 1.2 is fixed to a position on a side wall of the base 1 corresponding to the pulley 2.1. A conveying motor 4 is fixed to the outer wall of the side frame 1.2 for driving the corresponding pulley 2.1. In other words, the conveying motor 4 drives all the drive rollers 2 to rotate synchronously via the pulleys 2.1 and the transmission belt 3, thereby facilitating the forward conveyance of cardboard placed on the top surface of the base 1. The top of the packaging drive roller 2 is flush with the top surface of the base 1. To ensure smooth transportation of the cardboard, a plurality of guide wheels 1.3 are rotatably mounted on the top surface of the base 1 at the outer sides of the two ends of the rectangular groove 1.1. That is, the guide wheels 1.3 roll in contact with both sides of the cardboard to be coated, thus preventing the cardboard from lateral deviation.
[0029] Two support rollers 5 are positioned transversely above the front and rear ends of the base 1. Supports 5.1 are rotatably mounted on each end of the support rollers 5. Supports 5.1 are fixedly attached to the front and rear ends of the base 1. The front and rear support rollers 5 support and guide the film strip, keeping it parallel to the paperboard. The bottom surface of the film strip is an adhesive layer.
[0030] The bottom end of vertical plate 6 is fixed to one side of the top surface of base 1; one side of top plate 7 is fixedly connected to the top of the inner wall of vertical plate 6; lifting plate 8 is arranged parallel to the underside of top plate 7; and telescopic cylinder 11 is used to drive the vertical movement of lifting plate 8. To ensure the smooth movement of lifting plate 8, multiple linear bearings 7.1 are fixedly mounted vertically on top plate 7, located outside telescopic cylinder 11. Guide rods 8.1 are fixedly connected to the top surface of lifting plate 8, and are slidably connected to linear bearings 7.1. That is, when telescopic cylinder 11 pushes and pulls lifting plate 8 vertically via the piston rod, guide rods 8.1 slide along linear bearings 7.1, providing guidance.
[0031] The top of the frame-shaped die cutter 9 is fixedly connected to the outer edge of the bottom surface of the lifting plate 8. The bottom of the frame-shaped die cutter 9 is provided with a cutting edge, the contour of which is consistent with the outer contour of the cardboard to be laminated. When the lifting plate 8 moves down to the lowest position, the outer walls of the frame-shaped die cutter 9 are tangent to the guide wheels 1.3.
[0032] The film pressing assembly 10 comprises a horizontal frame 10.1 fixed to the front end of the bottom of the lifting plate 8; a swing arm 10.2, hinged at its top end to each end of the horizontal frame 10.1 and tilted backward at its bottom end; a pressure roller 10.3, with its central axis pivotally connected to the bottom end of the swing arm 10.2; a base 10.4, hinged at its bottom end to the swing arm 10.2; a vertical rod 10.5, fixed at its bottom end to the top surface of the base 10.4 and slidingly connected to the lifting plate 8; and a spring 10.6 mounted on the bottom of the vertical rod 10.5. To reduce friction caused by the sliding movement of the vertical rod 10.5, linear bearings 8.2 are fixedly mounted and rotatably connected to the vertical rod 10.5 at positions corresponding to the vertical rod 10.5 on the lifting plate 8. The bottom end of the swing arm 10.2 is tilted forward at an angle of 15 to 45 degrees.
[0033] In summary, when laminating cardboard, the cardboard is first placed on the top surface of the rear end of the base 1, and the synchronously rotating drive roller 2 conveys the cardboard forward. When the cardboard moves forward to the laminating station, the telescopic cylinder 11 gradually extends the telescopic rod, causing the lifting plate 8 to descend smoothly. The pressure roller 10.3 first contacts the film strip and gradually presses the film strip against the front end of the cardboard. As the lifting plate 8 continues to move downward, the vertical rod 10.5 moves upward relative to the linear bearing 2 8.2, that is, the bottom end of the swing arm 10.2 gradually swings upward, so that the pressure roller 10.3, supported by the swing arm 10.2, presses the film strip onto the cardboard from front to back. Finally, the frame die cutter 9 punches the film strip so that the film sheet attached to the cardboard is consistent with the contour of the cardboard. To complete the laminating process, the telescopic cylinder 11 contracts the telescopic rod, so that the lifting plate 8 is reset upward, and the swing arm 20.2 is swung downward and reset under the action of the spring 10.6, so as to prepare for the next cycle of laminating operation.
