The invention discloses a roll paper packaging machine in the field of daily supply production equipment. The roll paper packaging machine comprises a box body. An upper partition plate and a lower partition plate are arranged in the box body. Through holes are formed in the wall bodies on the two sides of the box body, and two rolling wheel sets are arranged in the box body. Limiting holes used for allowing the rolling wheel sets to pass are formed in the upper partition plate and the lower partition plate. A clearance exists between the two rolling wheel sets, a motor used for driving the rolling wheel sets is arranged in the box body, and the two rolling wheel sets are connected through a gear. A lifting mechanism is further arranged in the box body and comprises a cam, a limiting groove and a connecting rod, and the connecting rod is located above the limiting groove. The two ends of the connecting rod are fixedly connected with a cutting knife and a storage groove correspondingly.A rotating rod used for fixing roll paper is rotationally connected to the box body. According to the scheme, manual bonding of roll paper plastic packaging paper is not needed, the work efficiency is improved, and meanwhile the problem that the skin of an operator is hurt is avoided.
