Full-automatic laminating machine

Abstract

The invention discloses a full-automatic laminating machine which comprises an emptying mechanism, a laminating mechanism, a material collecting mechanism and a programmable logic controller (PLC), wherein the emptying mechanism is provided with a storage rack which is provided with a locating seat; the storage rack is formed by connecting two side plates by a connecting rod; the storage rack is arranged on a base in a sliding way; the base is provided with a first driving mechanism connected with the storage rack in a transmission way; a pressure sensor and a distance sensor are arranged between the emptying mechanism and the laminating mechanism; the pressure sensor is provided with a pressure transmission roller; paper passes through the distance pressure and comes round the pressure transmission roller from the upper part; a magnetic powder clutch connected with an inflatable shaft is arranged at one side of a mounting seat by a mounting plate; the locating seat comprises a fixed seat and a movable seat; the inflatable shaft is tightly held by the movable seat and the fixed seat which are in a sliding fit way. The full-automatic laminating machine is capable of automatically adjusting the tensity of the paper so as to enable the tension of the paper to be constant, is capable of automatically correcting the deviation of the paper, can be used for loading and unloading roll paper, and is more convenient and faster.

Description

technical field [0001] The invention relates to a laminating machine, in particular to an automatic laminating machine. Background technique [0002] The roll laminating machine is a device that coats the plastic film with an adhesive, and combines it with the printed matter that uses paper as the substrate, and pressurizes the roller to form a paper-plastic product. The traditional roll laminating machine includes a feeding mechanism for releasing paper, a laminating mechanism for releasing a film and covering the film on the paper, and a receiving mechanism for collecting the coated paper-plastic products. During the lamination process of film and paper, the roll diameter of the roll paper on the unwinding mechanism will gradually become smaller as the paper gradually decreases, and as the roll diameter of the roll paper becomes smaller, the tension of the paper will also increase. Then it becomes smaller, and the acceleration and deceleration of the laminating machine wi...

AI Technical Summary

Problems solved by technology

During the lamination process of film and paper, the roll diameter of the roll paper on the unwinding mechanism will gradually become smaller as the paper gradually decreases, and as the roll diameter of the roll paper becomes smaller, the tension of the paper will also increase. Then it becomes smaller, and the acceleration and deceleration of the laminating machine will also affect the tension of the paper. No matter what the situation causes the tension of the paper to change so that it cannot maintain a constant tension when laminating with the film, it will affect the tension of the paper. The quality of the film, and if there is a deviation in the width of the paper during the conveying process, it will also affect the quality of the film, and when installing or replacing the roll paper, the roll paper must be manually removed from the feeding mechanism or the receiving mechanism. It is obviously time-consuming and labor-intensive to lift up and down, which is not convenient and efficient enough
