When using the edge ironing device, generally, the edge of the papermaking felt is set at the bottom of a heating device, so that the heating device presses against the top of the felt. Generally, it is necessary to manually press the heating device against the top of the felt, so that the fibers on the side of the felt are melted, and thus the edge sealing is well completed.

[0003] Existing technologies such as the utility model with the authorization announcement number CN201821325997.8 disclose a novel papermaking felt edge ironing device, which includes an edge ironing device housing. A motor is installed in the edge ironing device housing. A bracket is fixedly connected to the inner wall of the edge ironing device housing near its bottom. A heating pipe is installed on the bracket. The bottom end of the output shaft of the motor passes through the bracket and is fixedly connected to a first fan blade. The top end of the output shaft of the motor is fixedly connected to a second fan blade. An air inlet hole is opened at the top of the edge ironing device housing. An air outlet hole is opened at the bottom of the edge ironing device housing. An angle adjustment device is installed on the side of the edge ironing device housing. Through the cooperation of the above structures, on the one hand, it can iron the edges of the shaped papermaking felt, and on the other hand, it can adjust the angle of the edge ironing device housing during use, which is convenient for operation.

[0004] The inventor found in daily work that the edge ironing device still has at least the following problems: When using the edge ironing device, generally, the edge of the papermaking felt is set at the bottom of the heating device, so that the heating device presses against the top of the felt.
