1. Influence of coating gap on coating quantity
The results show that the coating gap of solventless laminating machine has obvious influence on coating amount, while the coating gap of solventless laminating machine varies with different manufacturers. It can be roughly divided into: the material of metering roll and transfer steel roll is affected by temperature; the mechanical (bearing clearance) clearance of coating roller itself; the mechanical (bearing clearance) clearance of metering roller; and the receiving machine of metering roll In a word, this kind of problem is difficult to find, and it is a kind of soft problem.
2. Effect of temperature on coating quantity
The glue used in solventless laminating machine is greatly affected by temperature. With the difference of temperature of solventless compound glue, the fluidity and viscosity of glue will change greatly; at the same time, the temperature change of glue will cause thermal expansion and cold contraction of metering roll and coating roller, and finally affect the coating gap.
3. Influence of transfer cot on coating weight
The hardness, coaxiality and smoothness of transfer cots directly affect the coating amount; the corrosion resistance of transfer cots directly affects the coating amount; the pressure of transfer cots directly affects the coating amount; and the pressure of transfer cots is directly affected by the air source pressure. In short, such problems have a great impact on the amount of coating.
4. The influence of rotation speed of coating mechanism on coating weight
The coating weight of solventless compound machine is adjusted by adjusting the ratio of coating roller and transfer steel roller, so the stability of linear speed of coating roller and transfer steel roller has great influence on coating amount.
