The invention provides a heat transfer base paper production system and aims at solving the technical problems of poor evenness, low tightness and low toughness of heat transfer base paper. The production system comprises a forming net, a once forming device, a secondary forming device and a water absorption device, a first squeezing plate and a second squeezing plate which move synchronously in the secondary forming device efficiently squeeze an sizing agent on a forming area so that fiber in the sizing agent can be dehydrated and compressed, bubbles in the sizing agent are removed by using through holes which are formed in a staggered mode, and paper achieves a breathing effect when squeezing is conducted, so that the toughness of the paper is improved, and the quality of the heat transfer base paper is improved.
