Certificate thermoplastic packaging device, certificate printer and certificate card printing production line

The utility model discloses a certificate thermal plastic packaging device, a certificate printer and a certificate card printing production line, the certificate thermal plastic packaging device, each roll shaft assembly and each heating assembly are arranged at intervals, so that a continuous conveying channel is formed at the joint of each roll shaft and each heating gap; each roller shaft canrotate; the working temperature of the first heating assembly is lower than that of the second heating assembly. The certificate conveying device has the beneficial effects that the roll shaft assembly can make contact with the surface of a certificate in the autorotation state, power is provided for the certificate in a rolling friction mode, and the certificate is driven to move in the conveyingchannel. The certificate sequentially passes through the first heating assembly and the second heating assembly in the conveying channel, so that the temperature of the certificate is gradually increased, and the plastic pack
