Double-sided Laminating Machine

 Specification:

Laminator heat dissipation problem solving method

The laminator has high requirements for temperature control. If the temperature is too high, the heating time is too long, the film quality will drop, and there is no heating.

If the drying temperature is too high, the surface of the adhesive is crusted, causing foaming of the film. Excessive thermal stress can also cause the film to lose its elasticity, resulting in reduced performance and tearing.

There are three methods of heat dissipation in physics: conduction, convection and radiation. The first two have been eliminated. It is only solved by thermal radiation.

Radiation heat dissipation can be unaffected by the temperature of the medium around the object. As long as the temperature of the object exceeds zero, the object must go out. Radiant heat, but it is very small in terms of the amount of heat radiation of the object itself. It can't solve the problem of heat dissipation and cooling of the object. Only increase the amount of heat radiation of the object to reduce the temperature of the object, so that a layer of heat-dissipating paint is applied on the surface of the object. The heat-dissipating paint greatly enhances the amount of heat radiation of the object to reduce the temperature of the object.we are double-sided laminating machine manufacturer.

The heat-dissipating coating enhances heat exchange in the form of infrared radiation, and the heat dissipation is not affected by the surrounding medium. The heat dissipation of the paint can be used in a vacuum environment. The ZS-411 radiation heat-dissipating paint improves the heat exchange and also has a good self. Clean, insulating, anti-corrosive, waterproof, acid and alkali resistant, easy to construct.

Laminating machine manufacturing problems and applications

Problems and solutions in the laminating process of laminating machine.

One: crumpled paper

1The film has a large pulling force to produce vertical creases. Adjust the film tightness 2 The film itself is tight and uneven. Adjust the film transfer stick

2pressure is too high, the temperature is too high, wrinkles, adjust the pressure, and temperature

3rubber pressure stick deformation, disassemble the pressure stick, re-grind

4The paper is damp, keep the working environment and the paper dry or use drying in the laminating

Two: wrinkle film

1The temperature is too high, the temperature is lowered appropriately, and the temperature required for adjusting various membranes is reduced.

2Adhesive stick adjustment imbalance, adjust the balance of the film stick

3film stacking time is too long, replace the film

4film tension is too large or too small, adjust the film tightness

Three: there are snowflakes on the product

1.The printed matter is excessively powdered, and the powder on the printed matter is swept before the film is covered.

2,the pressure of the pressure roller is not suitable, the solution is to correctly adjust the pressure of the pressure roller

3,the temperature is too low, adjust to the appropriate temperature four: bubble appears.

Pre-coated laminating machine consists of pre-coated plastic film unwinding, automatic print input, hot-pressing area compounding, automatic winding, four main parts, as well as mechanical transmission, pre-coated plastic film flattening, vertical and horizontal slitting, computer control system And other auxiliary devices.
