A sealing machine is a machine that seals a container filled with a package. There are many materials for making packaging containers, such as paper, plastic, glass, plastic film, ceramics, metal, composite materials, etc., and the shape and physical properties of the packaging containers are also different. Therefore, the sealing form and sealing machine used are also Different.
According to the material thickness of the sealing material and the size of the packaging bag, the speed and temperature adjustment of the multifunctional continuous sealing machine are carried out to achieve satisfactory sealing quality and high production efficiency.
1. There are related relationships between sealing material, sealing temperature and sealing speed. The same material, when the temperature is high, the speed can be increased accordingly; when the speed is low, the temperature should be lower. The thicker the film thickness, the higher the temperature and the lower the speed, and vice versa.
2. Before the actual operation, it is necessary to do the preliminary test, adjust the temperature and the corresponding sealing temperature, and repeat it several times to find the temperature and speed that the sealing quality and efficiency are satisfactory, and then carry out the formal operation.
3. When sealing a single-layer plastic film such as ordinary polyethylene, the fan must be turned on for cooling. In the initial test, the temperature should be gradually increased to prevent the temperature from being too high, so that the film melts and sticks to the sealing tape. If the bonding occurs, the peeling should be removed in time to ensure the sealing quality and protect the sealing tape.
4. When the composite film material is sealed, the selected temperature range is much higher than that of the single-layer film, and generally no fan cooling is required.
5. The pressure of the embossing wheel is closely related to the quality of the sealing. It is advisable to adjust the pressure to a clear pattern. The pressure is too high, affecting the life of the parts, the pressure is too low, the pattern is not clear, and the sealing strength is lowered.
