Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper box production, in particular to a paper box laminating device. Background Art

[0002] Carton forming requires multiple operations such as corrugated paper forming, laminating, paper mounting, cutting, and box gluing. In order to improve the strength and durability of the carton, a waterproof film is usually glued on the outer surface of the carton. During the laminating process, the film with the waterproof film is conveyed by the feed roller. However, under this structure, since the feed roller cannot float elastically, when the tension on one side of the film is greater than the tension on the other side, the waterproof film on the film will wrinkle on the feed roller, which will affect the subsequent film processing and make the quality of the carton after forming substandard. Utility Model Content

[0003] The utility model aims to solve the problem of wrinkles on the waterproof film in the prior art and proposes a carton film covering device.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A carton laminating device is designed, comprising a frame, a lifting structure is provided on both sides of the frame, a bracket is installed on the lifting structure, a driven roller and a steering roller are rotatably installed on the bracket, a connecting plate is fixedly connected to the bracket, a sliding rod is slidably fitted on the connecting plate, a mounting plate is fixedly connected to the sliding rod, a first spring is sleeved on the sliding rod, a plurality of pressure rollers are rotatably installed on the mounting plate, a motor seat is fixedly connected to the bracket, a motor is fixedly connected to the motor seat, and a winding roller is fixedly connected to the output end of the motor.

[0006] Preferably, the lifting structure comprises a cylinder, a cylinder base is fixedly connected to the top of the frame, the cylinder is fixedly connected to the cylinder base, a connecting piece is fixedly connected to the output end of the cylinder, and the connecting piece is fixedly connected to the bracket.

[0007] Preferably, the bracket is provided with two sets of telescopic structures, and the telescopic structures include two guide tubes and a guide column. The two guide tubes are fixedly connected to the bracket, and both ends of the guide column can be slidably engaged in the guide tubes. A second spring is provided in the guide tube, and a rotating seat is fixedly connected to the guide column.

[0008] Preferably, the rotating seats of one group of telescopic structures are connected to the driven roller, and the rotating seats of another group of telescopic structures are connected to the steering roller.

[0009] Preferably, a conveyor belt is provided on the frame to transport the cartons.

[0010] The utility model provides a carton laminating device, which has the beneficial effect that during the laminating process, the second spring cooperates with the guide column to make the driven roller and the steering roller have an elastic supporting force in the horizontal direction. When the tension on both sides of the film roll is different, the second spring will change to prevent the film roll from being subjected to excessive tension, which will cause the waterproof film on the film roll to deform, thereby preventing the waterproof film from wrinkling.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-2 A carton laminating device includes a frame 1, a conveyor belt 5 is provided on the frame 1 to transport cartons 6, a lifting structure is provided on both sides of the frame 1, the lifting structure includes a cylinder 3, a cylinder base 2 is fixedly connected to the top of the frame 1, the cylinder 3 is fixedly connected to the cylinder base 2, a connecting piece 301 is fixedly connected to the output end of the cylinder 3, and the connecting piece 301 is fixedly connected to the bracket 4.

[0019] When laminating the carton 6, the carton 6 is conveyed to the laminating station on the frame 1 by the transmission belt 5, and then the cylinder 3 is started, and the cylinder 3 drives the bracket 4 to move from top to bottom.

[0020] like Figure 2-4 As shown, a driven roller 10 and a steering roller 11 are rotatably mounted on the bracket 4, a connecting plate 12 is fixedly connected to the bracket 4, a slide bar 13 is slidably fitted on the connecting plate 12, a mounting plate 15 is fixedly connected to the slide bar 13, a first spring 14 is sleeved on the slide bar 13, a plurality of pressure rollers 16 are rotatably mounted on the mounting plate 15, a motor seat 7 is fixedly connected to the bracket 4, a motor 8 is fixedly connected to the motor seat 7, and a winding roller 9 is fixedly connected to the output end of the motor 8.

[0021] The driven roller 10 is used to place the film with the waterproof film. The film starts from the driven roller 10, passes through the steering roller 11 and the pressure roller 16, and is fixed to the winding roller 9.

[0022] During the movement of the bracket 4 from top to bottom, under the elastic force of the first spring 14, the pressure roller 16 squeezes the film onto the carton 6. The surface of the carton 6 is sprayed with adhesive. When the film contacts the carton 6, the waterproof film on the film will adhere to the surface of the carton 6, thereby completing the laminating work of the carton.

[0023] like Figure 4-5 As shown, two groups of telescopic structures are provided on the bracket 4, and the telescopic structures include two guide tubes 17 and a guide column 18. The two guide tubes 17 are fixedly connected to the bracket 4, and both ends of the guide column 18 are slidably fitted in the guide tubes 17. A second spring 19 is provided in the guide tube 17, and a rotating seat 20 is fixedly connected to the guide column 18. The rotating seat 20 of one group of telescopic structures is connected to the driven roller 10, and the rotating seat 20 of the other group of telescopic structures is connected to the steering roller 11.

[0024] During the laminating process, the second spring 19 cooperates with the guide column 18 to ensure that the driven roller 10 and the steering roller 11 have an elastic supporting force in the horizontal direction. When the tension on both sides of the film is different, the second spring 19 will change to prevent the film from being subjected to excessive tension, which may cause the waterproof film on the film to deform, thereby preventing the waterproof film from wrinkling.
