Double Blister High Frequency Heat Laminating Machine

Double Blister High Frequency Heat Laminating Machine is a widely used equipment in the packaging industry, especially suitable for crimping, fusing and sealing packaging of polyvinyl chloride (PVC) and other plastic materials. The following is a detailed analysis of the double blister high-frequency heat sealing machine:

I. Equipment Overview

Double Blister High Frequency Heat Laminating Machine through the heat generated by high frequency electromagnetic field, two or more pieces of blister material will be rapidly heated and bonded under the action of high-frequency current to achieve seamless sealing of packaging materials. This equipment is widely used in the packaging production of medicine, food, cosmetics and other industries, with high efficiency, environmental protection, good sealing and other advantages.

Working Principle

High-frequency electromagnetic field generation: the high-frequency generator inside the equipment generates high-frequency electromagnetic field, usually working frequency is 27.12 MHz or 40.68 MHz.

Electromagnetic field into thermal energy: high-frequency electromagnetic field through the conductive medium (such as electrodes) conducted to the blister material, so that the polar molecules within the material to produce high-frequency vibration, which is converted into thermal energy.

Material melting and bonding: under the action of high-frequency thermal energy, the surface of the blister material rapidly warms up and reaches a molten state, at which time the two or more pieces of material are tightly adhered to each other through the external pressure to achieve seamless bonding.

Third, the main technical parameters

Input power: common input power 15KVA, 18KVA, 20KVA, 25KVA, etc., according to the production requirements to choose the appropriate power.

Rectifier: SILICON DIODE silicon diode rectifier is used to ensure current stability.

Oscillator tube: such as 7T69RB, E3069, E3130, 8T85RB and other models to provide high frequency oscillation signal.

Pressure: Depending on the equipment model, the pressure range can vary from 500kg to 1000kg.

Electrode spacing: usually 200mm to ensure effective transmission of high frequency electromagnetic field.

Active Size and Electrode Size: According to the production demand, the working table and active electrode size of the equipment will be different to adapt to different specifications of blister materials.

Fusing time: adjustable range of 0-10 seconds, set according to the material thickness and bonding requirements.

Fourth, the use of characteristics

High efficiency: high degree of automation, able to quickly complete a large number of blister materials heat sealing packaging.

Precision: through precise control of temperature, pressure and time and other parameters, to ensure the stability and consistency of the quality of heat sealing.

Environmental protection: no need to use glue and other adhesives in the process of high-frequency thermal lamination, reducing the pollution of the environment.

Multi-functionality: suitable for heat laminating and packaging of various plastic materials, such as PVC, PET, PETG, etc.

V. Operating Precautions

Before operation, make sure the equipment is placed stably, the power supply is wired correctly and grounded well.

Regularly check the electrical components and mechanical parts of the equipment to ensure that they are in good condition.

In the operation process, attention should be paid to safety, avoiding hands or other objects touching the high temperature parts.

Adjust the parameters of the equipment according to the production requirements to ensure that the heat sealing effect is optimal.

To sum up, double blister high frequency heat laminating machine is a kind of high efficient, precise and environmentally friendly packaging equipment, which plays an important role in pharmaceutical, food, cosmetic and other industries.
