Working Principle

• Flame treatment part: The flame treatment machine generates high-temperature flames through a double flame gun. When the flame contacts the surface of bottles and cups made of PP (polypropylene) and PE (polyethylene) materials, the molecular structure of the material surface will change. The surface of these materials is usually low in surface energy and non-polar. Flame treatment can introduce polar groups such as hydroxyl and carboxyl groups on the surface, thereby increasing the surface energy of the material and improving the surface wettability and adhesion.

• Conveyor belt part: The stainless steel conveyor belt is driven by a motor to transport plastic products such as bottles and cups to the position where the flame gun is treated. It can stably transport items and ensure the continuity of the flame treatment process.

• Rotating fixture part: The rotating fixture can fix the bottle or cup and rotate it during the flame treatment process. This ensures that the entire surface of the bottle or cup can be evenly flame treated to avoid the situation where the part is not treated or overtreated.

• Key panel operation: The flame size of the flame gun, the speed of the conveyor belt, the rotation speed of the rotating fixture and other parameters are controlled through the key panel. Operators can flexibly adjust these parameters according to the requirements of different PP and PE material products, such as the size, shape, and degree of treatment of bottles and cups.

• Safety shield: It is mainly to prevent operators from being exposed to flames or being burned by high temperatures, and also to avoid splashes that may be generated during flame treatment from causing damage to the surrounding environment and personnel.

Application scenarios

• Packaging industry: During the production process of plastic bottles and plastic cups, their surfaces are flame treated for subsequent printing, labeling and other processes. For example, after flame treatment of beverage bottles, cosmetic bottles, disposable plastic cups and other products, labels or printed patterns can be better attached to the surface, improving the appearance quality of the product.

• Plastic product processing: For some PP and PE plastic products that need to be coated or bonded to other materials, flame treatment is an effective pretreatment method that can enhance the bonding between different materials.

Advantages

• Uniform treatment effect: Due to the cooperation of the rotating fixture and the conveyor belt, the surface of products such as bottles and cups can be evenly flame treated, ensuring the consistency of treatment quality.

• Easy to operate: Through the key panel operation, various parameters can be adjusted simply and quickly to meet different production requirements.

• High safety: The safety shield effectively ensures the safety of operators and the surrounding environment, reducing the possibility of accidents.
