Automatic cutting device: The cutting length can be set freely according to the paper size, and the speed can be controlled freely. The linkage operation system of the unit, with the speed of the host, is automatically increased and decreased, the operation is simple, the labor cost is saved, and the labor intensity of the operator is reduced. Knife disc rotating blade design, 4 sets of blades of rotary knife seat, can be fine-tuned and controlled, easy to operate; when adjusting, cooperate with the pressure roller to interact. Equipped with a reverse paper roller, it can cut thin paper, and papers of more than 128 grams can be automatically cut online; equipped with an automatic winding device, which can be rolled into a roll for paper with poor quality and hardness.
The film unwinding shaft of the automatic laminating machine adopts magnetic powder braking to maintain stable tension. The unique pneumatic film stretching device ensures the tightness of the film during film pressing and film lifting, which effectively prevents the film rolling failure.
The small film laminator has a small footprint, simple operation and fast speed. The feeding table adopts a conveyor belt, and the output adopts a powered roller, which can withstand heavy heavy plates. It is widely used in stainless steel plates, aluminum plates, aluminum plastic plates, UV baking paint plates, iron plates, decorative cabinet doors, baking paint plates, paint panels , Acrylic board, color steel plate, fireproof board, plexiglass board, cabinet door laminating machine, signage, high-end furniture board, color coated board, electrical appliance PVC and other flat coating, affixed, pressed with self-adhesive PE protective film, Electrical cabinets, decorative films, etc., in order to prevent pollution, corrosion, power transmission and scratches during production, processing, transportation, storage and use, protect the original smooth surface and the explosion-proof lens.
This series of film laminating machine is composed of upper and lower rubber rollers, frame, power transmission and control device, film supporting frame, etc. It has the characteristics of flat film lamination, no wrinkles, no bubbles, simple operation and long service life.
1. Operate reasonably in accordance with the rules of the manual, and prohibit all improper operations
2. Regularly check the parts of the laminating machine to see if it is damaged, and replace it immediately if it is damaged
3. For the water coming from the flower planter, when the earth shovel is lowered, the height of the ridge can be increased, but at the same time, the sowing opener and the depth-limiting barrel should be raised to the corresponding level
When the earth shovel is raised, the height of the ridge can be reduced, and at the same time, the sowing opener and the depth-limiting barrel should also be adjusted downward to the corresponding position.
A good laminating machine not only requires the operation specifications, but also the maintenance is equally important. Strictly follow the regulations on the operation and maintenance of the laminating machine, and develop a good habit of using the laminating machine, so as to extend the life of the machine.
The automatic laminating machine is divided into three parts: gluing, drying tunnel and hot pressing.
(1) Glue part
The gluing part is equipped with an adjusting device to adjust the amount of gluing to meet the requirements of different printed parts. The gluing roller adopts rubber roller or steel roller.
(2) Drying tunnel part
The drying tunnel is generally 2~3m long. The drying tunnel entrance of the automatic laminating machine is provided with an infrared lamp tube and an electric fan. There is also a high-power electric heating tube and exhaust fan on the upper part of the drying path of the automatic automatic film laminating machine. The temperature can be adjusted to dry the adhesive and eliminate the exhaust gas.
(3) Hot pressing part
This part is the key to the coating, which is directly related to the adhesion fastness of the coating product. The principle of hot pressing is that the adhesive can quickly infiltrate and penetrate into the surface layer of the printed matter in the molten state, so as to obtain a strong bonding interface layer. The hot pressing part consists of a set of rollers. One of the hollow metal rollers is equipped with an electric heating tube, and the temperature can be controlled automatically. The pressure of this group of rollers can be adjusted.
1. The drying temperature is controlled between 50-70℃, which can fully evaporate the solvent without causing the film to overheat and deform;
2. Compound temperature The temperature of the impression cylinder is controlled at 70-90℃, which can melt the adhesive and the film will not be deformed by overheating;
3. Compound pressure Ensure that the axial pressure of the impression cylinder is consistent, and the pressure should be kept within 150-250kg/cm2;
4. Adhesive coating The coating should be thin, controlled at 3-8g/cm2, and the thickness is 5-8μm, to avoid excessive coating;
5. Machine speed: The single sheet of paper should be controlled at 35-45 sheets/minute, and the roll paper should be at 3-10 meters/minute, in addition to other parameters;
6. Film tension The tension is adjusted to the minimum to achieve the correct coating and compounding, to avoid excessive tension;
7. Cylinder accuracy The impression cylinder requires a smooth and clean surface with no scratches or pits. It is necessary to ensure mechanical accuracy indicators such as ellipticity and concentricity;
8. Environmental factors To keep the environment clean, air purification devices are required. Control workshop temperature and humidity to prevent deformation of paper or film;
9. Ink thickness should be deep ink and light printing, to avoid the surface tension drop caused by too thick ink layer, and make the laminating film not firm;
10. Ink drying Ink drying should be thorough to avoid blistering;
11. Ink additives To control the amount of desiccant added to prevent the ink layer from crystallizing. The surface of the crystallized ink will have a loose film.
