The coating gap, temperature, transfer rubber roller, and rotation speed of the coating mechanism all have a great influence on the coating amount. This paper analyzes one by one to solve this detail problem.
1. Effect of coating gap on coating amount
The coating gap of the solventless laminating machine has a significant influence on the coating amount, while the solventless laminating machine has different coating gaps depending on the manufacturer; it can be roughly divided into: the temperature of the measuring roller and the transfer steel roller are subject to temperature. Influencing factors; the mechanical (bearing clearance) gap factor of the coating roller itself; the mechanical (bearing clearance) gap factor of the metering roller itself; the stability of the metering roller to the mechanical vibration. In short, such problems are difficult to find, and it is a kind of Soft problem.
2, the effect of temperature on the amount of coating
The glue used in the solventless compound machine is greatly affected by the temperature. With the temperature of the solventless compound glue, the fluidity of the glue and the viscosity of the glue will change greatly. At the same time, the temperature change of the glue will affect the metering roll. The coating roller undergoes thermal expansion and contraction, and finally, affects the coating gap.
3. Effect of transfer rubber roller on coating amount
The hardness, coaxiality and smoothness of the transfer rubber roller directly affect the coating amount; the corrosion resistance of the transfer rubber roller directly affects the coating amount; the pressure of the transfer rubber roller directly affects the coating amount; and the pressure of the transfer rubber roller directly Affected by the pressure of the source. In short, such problems have a great impact on the amount of coating.
4, the influence of the speed of the coating mechanism on the coating amount
The coating amount adjustment of the solventless laminating machine is performed by adjusting the ratio of the coating roller to the transfer steel roller, and thus the stability of the linear velocity of the coating roller and the transfer steel roller has a great influence on the coating amount.
