Impressing device of adhesive binding machine

The invention relates to an impressing device of an adhesive binding machine. The impressing device comprises a rack, and an upper pressing wheel shaft and a lower pressing wheel shaft arranged on the rack; the upper pressing wheel shaft is fixedly sleeved by an upper impressing wheel; the lower pressing wheel shaft is fixedly sleeved by a lower impressing wheel; and the upper pressing wheel shaft and the lower pressing wheel shaft are connected with a driving device through gear transmission devices to drive the upper impressing wheel and the lower impressing wheel to move up and down. The impressing device is reasonable in structural design and high in automation degree, realizes quick adjustment of pressure magnitude of indentation lines through setting of a controller touch screen and adjustment of a servo motor, is simple in structure, stable in operation, fast and precise, and improves the book processing quality. 本发明涉及种胶订机的压痕装置，包括机架，设于机架上的上压轮轴和下压轮轴；所述上压轮轴上固定套接有上压痕轮，所述下压轮轴上固定套接有下压痕轮；该上压轮轴和下压轮轴通过齿轮传动装置与驱
