How To Deal With These Common Problems Of Plastic Bag Making Machines

Plastic bag making machine is suitable for hot cutting of plastic fiber and chemical fiber materials. The machine uses an electric heating cutter, and the cutting after hot cutting will automatically seal and not fall apart, without rough edges. The heat has automatic fixed length and automatic cutting in one, and adopts automatic operation control. It has the characteristics of high degree of automation, fast speed, low energy consumption, and low cost of use.
1. Does incomplete heat sealing cause content degradation?
A film with good anti-pollution heat sealing 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 heat sealing is too high; B is too large; C 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 in the process of curing, part of it penetrates into the film. Due to the influence of penetration, the toughness (resistance) of the substrate has decreased, which increases the brittle fracture; G plastics have increased heat after cooling and placement, which increases the tendency to become brittle.
Solution: 1. According to the different materials of the inner sealing layer, select the appropriate processing and heat sealing time; 2. Improve the plane condition of the upper heat sealing knife to make the surface flat; 3. Select a silicon pad with appropriate hardness.
3. What should I do if the upper and lower alignment is not accurate?
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.
