Self-adaptive elastic laminating device for carton forming

Abstract

The invention provides a self-adaptive elastic laminating device for carton forming. A movable rod is movably connected to the tail end of a main rod, and a moving seat is movably arranged at the bottom end of the movable rod and slidably mounted in a clamping plate. A sticking roller frame is arranged on the outer side of the moving seat and slidably mounted in a fixed seat, and a laminating roller is arranged below the sticking roller frame. The main rod drives the moving seat at the bottom end of the movable rod to move up and down in a guide rail. When the clamping plate in the moving seatdrives a carton to move downwards, the positions of a metal sheet and a variable resistor are adjusted by movement of the moving seat in the guide rail, so that current in a coil connected with the variable resistor in series is adjusted. Therefore, a magnetic field generated by the coil pushes a magnet to push the sticking roller frame to move downwards, and synchronous movement of the stickingroller frame and the moving seat is guaranteed. Thus, a film on the surface of the sticking roller is in an elastic tensioning state, and the wrinkling phenomenon is avoided.

Description

technical field [0001] The invention belongs to the technical field of carton processing, and in particular relates to a self-adaptive elastic coating device for carton forming. Background technique [0002] Carton forming requires multiple operations such as corrugated paper forming, film lamination, paper mounting, cutting, and box gluing. After the corrugated cardboard is made into a carton, in order to improve the strength and durability of the carton, it is usually glued on the outer surface of the carton. A layer of film, in the process of laminating, the surface of the carton is coated by a specific laminating device. [0003] During the lamination process of the carton, the film cannot be maintained in a stretched state and is prone to wrinkles. In addition, it cannot be fully wrapped during lamination, so the quality of the carton after forming is not up to standard, and it cannot be cut automatically after lamination. The efficiency of the film is low. Therefore, ...

Problems solved by technology

[0003] During the lamination process of the carton, the film cannot be maintained in a tensioned state and is prone to wrinkles. In addition, it cannot be fully wrapped during lamination, so the quality of the carton after forming is not up to standard, and it cannot be automatically cut after lamination. The efficiency of the film is low, therefore, in view of this, the existing structure and defects are studied and improved, and an adaptive elastic film covering device for carton forming is provided, in order to achieve more practical value
