Application points of new semi-automatic pre-coating film laminating equipment

With the rapid development of China's national economy and the awareness of national environmental protection, the printing industry is increasingly demanding energy conservation, consumption reduction, emission reduction, and green safety. Green printing has also been put on the agenda by many printing companies. In order to carry out green printing, printing companies need to start from all aspects of the printing process. The post-press processing is naturally indispensable. Among them, the green pre-coated film laminating equipment has attracted the attention of many printing companies. In this article, the author will introduce the operation and adjustment points of the new semi-automatic pre-coated film laminating equipment, and I hope to help you.

Advantages of precoat film coating process

The precoat film coating process refers to a process of sizing a plastic film and then recombining it with a printed product. The advantages of this process are very obvious.

First of all, the biggest advantage of the precoat film coating process is green. Because no adhesive is used, there is no smell at the job site, it will not pollute the environment, and it will not affect the health of the operator.

Secondly, the pre-coating film laminating equipment does not require a binder heating and drying system, and the area occupied is small, and the film surface which is covered is not prone to wrinkles and bubbles, and the film production efficiency is high and the quality is good.

Structure and operation of a new semi-automatic pre-coated film laminating equipment

1. Structure of a new semi-automatic precoat film laminating equipment

Since the new semi-automatic precoat film laminating equipment is mainly coated with an automatic hydraulic device, the laminating pressure can be easily adjusted. The film is heated by a heat transfer oil or a quartz tube, and the temperature is stable and adjustable. The unwinding knife and the slitting knife are arranged on the unwinding frame, so the automatic slitting can be completed after the film is coated. It adopts frequency conversion control motor and is stable and reliable.

2. Operation of new semi-automatic pre-coating film laminating equipment

Install the pre-coated film on the center of the film-release roller, tighten the two ends, then adjust the pressure to ensure the film is stable and reliable, and place the tool holder according to the actual situation to cut the edge material; place the paper on the conveyor belt, adjust The position of the paper ensures that the paper is stable and does not appear skewed; the tension of the pre-coating film on the unwinding frame is adjusted, and the paper is fed into the front pressure roller assembly through the transition roller, and is heated and pressurized with the pre-coating film. After the film is passed through the post-rolling roller, it is slit by the movable pressing roller and finally falls on the collecting table. The receiving platform can be tilted to the outside corner, and then a vibration motor can be installed under the receiving platform, so that the receipt is neat.

It should be noted that when thick paper is coated, the coated paper passes directly through the back pressure roller; when the thin paper is coated, the coated paper is first passed through the adjustment roller, and then adjusted to form. Rear pressure roller.

Adjustment of new semi-automatic precoat film laminating equipment

The process practice shows that the film temperature and pressure are the main factors affecting the quality of the precoat film. Therefore, in the process of precoating film, it is necessary to adjust the precoat film coating equipment for these factors.

1. Temperature regulation

The temperature of the temperature controller on the new semi-automatic pre-coating film laminating machine should be controlled at about 70 °C. When the red light on the temperature controller is on, it indicates that the temperature has reached the requirement and can be produced normally.

2. Pressure regulation

(1) The front pressure roller is pressed by the automatic hydraulic pump, and the rotary switch can adjust the pressure. The pressure is generally controlled at 1~15Mpa.

(2) The back pressure roller adopts an eccentric gear, and the handle can be divided by shaking the handle.

(3) The movable pressing roller is to adjust the pressure between the two rollers by the cam, and the two rollers can be separated by shaking the handle.
