Description

Technical Field

[0001] The utility model relates to the technical field of laminating devices, in particular to a laminating device for producing color paper boxes. Background Art

[0002] A paper box is a tool that can be used for product packaging. A paper box is made of cardboard. Cardboard is easily damaged without an external plastic film and is easily broken during transportation. Therefore, laminating the surface of the paper box is indispensable in the production of the paper box. By covering the surface of the paper box with a transparent plastic film, the scratch resistance of the paper box can be increased, and the gloss can be increased, thereby improving the aesthetics of the paper box. Based on the prior art, it is found that in the existing laminating device, during the laminating process of the paper box board, the air at the joint between the film and the paper box board cannot be completely discharged. Therefore, after laminating, bubbles are easily formed on the surface of the paper box, which cannot be easily handled.

[0003] CN 222224546 U discloses a laminating device for facilitating the positioning of paper boxes, comprising a laminating mechanism; the laminating mechanism being the laminating device body, which is a rectangular structure; a pushing mechanism mounted on the laminating mechanism; a fixed member fixedly mounted on the top of the body; a moving mechanism mounted on the fixed mechanism; an adjusting member mounted within a threaded hole on the moving member; and a bottom member connected to the moving member via a spring. The laminating device is configured such that a motor on the fixed member drives the moving member to move within a moving groove, while the bottom of the bottom member is configured as an arc-shaped structure. When in contact with a carton board, the bottom member moves upward and compresses a spring, increasing the contact pressure between the bottom member and the carton through the spring's return action. As the moving member drives the bottom member to move, the bottom member assists in flattening bubbles generated on the surface of the carton board.

[0004] However, the moving direction of the moving parts of the above-mentioned laminating device is perpendicular to the conveying direction of the carton board. When the bubbles generated on the surface of the carton board are flattened by the bottom part, the bottom part will drive the carton board to move left and right on the conveyor belt. In the process of flattening the bubbles, if the carton board is in a moving state, the bubbles on the surface of the carton board will not be completely cleaned. If the carton board is in a stationary state, it will affect the overall efficiency of the carton laminating. Utility Model Content

[0021] In this embodiment, the elastic lifting assembly includes two groups of fixed frames 7, and the two groups of fixed frames 7 are fixedly installed on the front and rear sides of the frame 1 by bolts respectively. A movable groove 71 is provided inside the fixed frame 7, and limit platforms 72 are provided on the left and right sides of the movable groove 71. Guide rods 73 are fixedly installed on the two groups of limit platforms 72. The top of the guide rod 73 is fixedly connected to the top of the movable groove 71. A support seat 8 is provided in the movable groove 71. The support seat 8 is rotatably installed on the end of the movable roller 6 through a bearing. Slide seats 9 are fixedly installed on the left and right sides of the support seat 8. The slide 9 is slidably mounted on the guide rod 73, and the guide rod 73 is provided with a spring 10. The bottom end of the spring 10 abuts against the top of the slide 9, and the top end of the spring 10 abuts against the top end of the movable groove 71. The movable roller 6 is slidably mounted on the fixed frame 7 through the support seat 8. The movable roller 6 is limited by the limit platform 72 so that a certain gap is maintained between the movable roller 6 and the fixed roller 5. The gap is slightly smaller than the thickness of the carton board. When the carton board passes between the fixed roller 5 and the movable roller 6, the movable roller 6 is squeezed against the surface of the carton board under the action of the spring 10, thereby squeezing out bubbles.

[0022] In this embodiment, the transmission assembly includes a motor 11, which is rigidly fixed to the front side wall of the frame 1 through a motor bracket, a driving wheel 12 is fixedly mounted on the power output shaft of the motor 11, and the ends of the fixed roller 5 and the movable roller 6 are fixedly mounted with a driven wheel 13, and a tensioning wheel 14 is movably mounted on the front side wall of the frame 1, and the driving wheel 12, the driven wheel 13 and the tensioning wheel 14 are connected in series through a transmission belt 19, the inner side of the transmission belt 19 is in close contact with the driven wheel 13 on the movable roller 6, and the outer side of the transmission belt 19 is in close contact with the driven wheel 13 on the fixed roller 5, and the tensioning wheel 14 is rotatably mounted on a slider 15, and the slider 15 is slidably mounted on a guide rail. 16, the guide rail 16 is fixedly mounted on the front side wall of the frame 1, and an elastic telescopic rod 17 is provided below the guide rail 16, and the elastic telescopic rod 17 is fixedly mounted on the frame 1, and the push rod of the elastic telescopic rod 17 is fixedly connected to the slider 15, and the driving wheel 12 is driven to rotate by the motor 11, and the transmission belt 19 transmits power to the two sets of driven wheels 13. Since the diameters of the two sets of driven wheels 13 are the same, the rotation speed of the fixed roller 5 and the movable roller 6 is the same, avoiding relative sliding between the carton board and the fixed roller 5 and the driven roller 6, resulting in wrinkling of the coating surface. When the height of the movable roller 6 changes, the transmission belt 19 is always in a tensioned state through the tensioning wheel 14 under the action of the elastic telescopic rod 17.

The top surface of the transition plate 18 is flush with the top surfaces of the first conveyor belt assembly 3 and the second conveyor belt. The outer wall of the fixed roller 5 is tangent to the top surface of the transition plate 18. The transition plate 18 blocks the gap between the conveyor belt and the fixed roller 5 to prevent the carton board from getting stuck in the gap during transportation.

[0024] When the utility model is in use, the carton board is placed on the first conveyor belt assembly 3 and conveyed in the direction of the laminating mechanism 2, and the surface of the carton board is laminated by the laminating mechanism 2. After laminating, the carton board passes between the fixed roller 5 and the movable roller 6, and the motor 11 drives the fixed roller 5 and the movable roller 6 to rotate in opposite directions at the same speed to convey the carton board forward. At the same time, under the action of the spring 10, the surface of the carton board is squeezed by the movable roller 6, so that the bubbles on the surface of the carton board are completely squeezed out, and the bubbles are cleaned when the carton board is in a moving state, thereby ensuring the production efficiency of the carton laminating and preventing the carton board from moving on the conveyor belt.
