Description

Transfer composite paper tape sticking device and tape sticking method

technical field

The invention relates to a processing equipment for transfer composite paper, and more specifically relates to a device and a method for pasting tape on transfer composite paper.

Background technique

As the country's requirements for environmental protection are getting higher and higher, ordinary composite paper is used less and less because of the non-degradable base film on the surface. In order to meet the requirements of environmental protection, the printing industry has turned to transfer composite paper, that is, transfer aluminized paper for printing.

The production process of the existing transfer composite paper includes the following steps in turn: coating a release layer on the base film, vacuum aluminizing on the release layer to form a vacuum aluminized layer, compounding the vacuum aluminized layer with paper, and coating the base film The transfer composite paper is obtained by peeling off the release layer, and the transfer composite paper is rolled into a transfer composite paper roll. In order to improve the printing performance of the transfer composite paper, usually after the base film is peeled off from the release layer, a layer of varnish is printed on the release layer of the transfer composite paper, dried and rewound to make a finished product. A production method well known in the printing industry.

This process has quality defects such as sticking and rubbing in the winding process. In order to solve this quality defect, the applicant adopted an in-line peeling printing process or an in-line peeling cutting process, and applied for a patent at the same time as this application , the process steps of in-line peeling printing include sequentially unwinding the transfer composite paper roll with base film with an unwinder, peeling off the base film by the peeling unit, and printing on the transfer composite paper by the printing unit. The process steps of in-line peeling and cutting include sequentially unwinding the transfer composite paper roll with base film by an unwinder, peeling off the base film by the peeling unit, and cutting the transfer composite paper into large or large sheets by the cutting unit.

This kind of production process generally adopts double-station non-stop unwinding machine to unwind. When the base film transfer composite paper with base film has not been peeled off, there are two ways to choose when switching between old and new paper rolls without stopping the machine. :

1. Lap joint. The overlapping method is that a part of the tail of the old paper roll is overlapped with the head of the new paper roll, and there is a certain overlap between them.

2. Splicing. The splicing method is that the tail of the old paper roll and the head of the new paper roll are spliced together, there is no overlap between each other, and there is a certain gap.

Because the switch is the transfer composite paper roll with the base film that has not been peeled off, the base film and the transfer composite paper need to be peeled and separated later, so the switch between the old and new paper rolls must be switched by splicing.

In order not to break the material when peeling off, both sides of the new and old paper roll switching joints need to be connected by tape. One piece of tape is respectively connected to the outer surface of the new paper roll switching joint base film and the old paper roll switching joint base film, and the other piece The adhesive tape connects the outer surfaces of the new paper roll switching joint paper and the old paper roll switching joint paper respectively.

Because the new and old paper rolls are all base film transfer joints with base film transfer composite paper, after the stripping process, the paper and base film are separated, and a piece of adhesive tape is left on the paper and base film respectively. Because the paper only has tape on the outer surface, under the action of external force, the paper between the new and old paper rolls is easy to break, resulting in shutdown failure, resulting in a large number of waste products, and also reduces production efficiency and increases the workload of the operator. .

1) Adsorb the single-sided tape cut into a certain size on the laminating roller, the side of the single-sided tape with glue is facing outward, and the side of the single-sided tape without glue is against the laminating roller;

2) After the base film and the transfer composite paper are peeled off by the peeling unit, when the spliced joint of the transferred composite paper passes through the detection mechanism, the detection mechanism detects the spliced joint and sends out a detection signal;

3) The control unit calculates the delay time according to the received detection signal, and controls the glue application mechanism to stick the adhesive tape to the splicing joint of the transfer composite paper according to the above delay time delay.

In step 3, after the control unit receives the detection signal, it calculates the delay time according to the distance from the detection mechanism to the lamination part, the delay time of the cylinder action and the traction speed of the traction mechanism. For example, if the delay time is 2 seconds, after the control unit receives the detection signal, wait for 2 seconds, and then control the glue application mechanism to start working, and then stick the tape to the splicing joint of the transfer composite paper.

The beneficial effect of the present invention compared with the prior art is that by pasting a layer of adhesive tape on the front of the splicing joint of the new and old transferred composite paper, there are adhesive tapes on both sides of the spliced joint of the new and old transferred composite paper, which strengthens the joint between the new and the old. The tensile strength of the splicing joints of the transfer composite paper prevents the new and old transfer composite paper splicing joints from breaking in the subsequent production process, resulting in shutdown failures, greatly improving the product yield and effectively reducing the production cost of the enterprise .
