The hot-cut bag making machine is suitable for hot cutting of plastic fiber and chemical fiber materials. The machine uses an electrically heated cutter, and the cut will automatically seal after hot cutting without loosening or burrs. The heat has automatic fixed length and automatic cutting in one, and adopts automatic operation control. It has the characteristics of high automation, fast speed, low energy consumption, and low cost of use.
1. Incomplete heat sealing causes the content to deteriorate?
A film with good anti-pollution heat sealing properties should be used, and ionic resin can be selected. It has excellent anti-pollution heat sealing properties.
2. How to solve brittleness or brittle fracture?
The reasons for the brittleness or brittle fracture of bag making machine products are: A. The heat seal is too high; B is too large; C. The heat sealing time is too long; D. The edge of the upper device is too sharp; E. The silicon at the bottom is too hard; F. During the curing process, part of it penetrates into the film. Due to the influence of penetration, the toughness (resistance) of the substrate decreases, which increases the brittle fracture; G. After cooling and placement, the heat of the plastic increases, which increases the tendency to become brittle.
Solution: 1. Choose the appropriate processing and heat sealing time according to the different materials of the inner sealing layer; 2. Improve the plane state of the upper heat sealing knife to make the surface flat; 3. Choose a silicon pad with appropriate hardness.
3. What should I do if the upper and lower parts are not aligned correctly?
The reason is: the film is uneven and has ruffles. The double floating rod force is too small, and some rods rotate unsteadily.
The tension of the double floating rod should be adjusted, and the relevant guide rods should be checked and adjusted.
