The clutch of the thermal lamination system adopts a more stable and reliable linear guide supporting hydraulic control system, and the winding tension system adopts a more advanced vector frequency conversion control technology.

Twin-screw co-extrusion release paper laminating machine      This machine adopts a twin-screw design, which can efficiently co-extrude and coat different types of plastics or film materials with paper substrates to form a paper-film composite material with good waterproofness and durability. The equipment has a compact design and is equipped with a precise temperature control system and an automated control interface to ensure that the film layer is uniform and bubble-free during the production process. It is suitable for industries such as food packaging and disposable tableware. The various components of the machine can be seen in the picture, including the twin-screw extrusion system, heating area, cooling device and coating system. The overall operation is smooth and the performance is stable.

  In the packaging industry, paper laminating technology is a very important production process. It can make the paper have higher durability, waterproof and moisture-proof performance and better display effect. The twin-screw extrusion release paper laminating machine is the key equipment to realize this process. First, let’s take a look at twin-screw extrusion technology. It uses two screws that cooperate with each other to complete the processes of heating, melting, mixing, extrusion and coating. One of the screws serves as a feeding screw, feeding raw materials (such as plastic particles or liquid materials) into the machine head for heating. The other screw serves as an extrusion screw, extruding the molten material from the machine head, and spraying the paint evenly onto the paper surface through the nozzle to form a thin film. The technical characteristics of paper laminating machines make them widely used in packaging, printing and other industries. For example, in the packaging industry, paper lamination can be used to produce paper or paper products with waterproof, moisture-proof, barrier and other properties, such as food packaging bags, medical packaging boxes, etc. In the printing industry, paper coating can improve the printing resistance, gloss and hiding power of paper, thereby achieving more exquisite printing effects. In short, the twin-screw extrusion release paper laminating machine is an efficient, environmentally friendly, and intelligent production equipment that has broad application prospects in packaging, printing and other industries.

The process flow of release paper lamination is as follows:   1.Raw materials The raw material used for this equipment is polypropylene. When selecting materials, you should choose polypropylene based on the extrusion performance based on the resin grade. Read the resin grade description in detail before heating.   2.Plastification This process is carried out in the extruder. The raw materials are fed into the hopper through the automatic feeding machine. After the raw materials enter the extruder barrel, they are heated through the feed preheating section, plasticizing section, extruder and metering section. Screw mixing plasticizes the pellets into a melt. The key point of the plasticizing process is temperature control. The method we generally use now is: One part is the barrel section and the barrel section. There are seven groups of heating, and the heating is carried out gradually from the first group to the seventh group. The second part is the "T" type mold, which is divided into thirteen groups. The general heating method is to heat the thirteen groups at the same temperature, and the pipe temperature is one group, and a fixed temperature can be set. The temperature is adjusted according to the thickness of the film cast by the "T" type die. Different raw materials have different melting points (the temperature is adjusted according to the actual temperature control zone).   3. Extrusion casting The dissolved material from the screw extrusion section passes through the filter plate of the machine head to turn the original vortex-like material into a flat flow, and then enters the "T"-shaped die to split the flow at both ends and become flakes. At the same time, observe whether the outflowing flakes are uniform. The material surface should be consistent and clear, and compounding can be started only after it is clear.   4. Composite embossing cooling, traction and winding The main components of this process are a pattern roller, a polyurethane roller, and a "T"-shaped die. The high-temperature molten film cast from the "T"-shaped die is pressed by the cooling pattern roller and the polyurethane roller cylinder, so that it adheres to the base material and is rapidly cooled to form a pattern. The material is pulled into the finished product and rolled up.

The working principle of the multi-layer laminating machine is to heat and melt a variety of materials through an extruder, then extrude them into films through a die, and then through cooling, compounding and other processes, the multi-layer films are compounded together.   Specifically, a multi-layer laminating machine usually consists of multiple extruders, each extruder extrudes different materials, and these materials merge at the extruder head to form a multi-layer film. Then, these films are cooled and solidified by cooling rollers, and then passed through laminating rollers to laminate the multi-layer films together. During the composite process, various additives, adhesives, etc. can also be added to improve the performance of the composite film. The working principle of multi-layer laminating machines involves knowledge in many fields such as material science, mechanical engineering, automation control, etc. Different types of multi-layer laminating machines may have some differences, but generally they all follow the above basic principles.
