Description

technical field [0001] The invention relates to the field of tissue packaging equipment for daily use, in particular to an eccentric reciprocating pressing, cutting and packaging device and a packaging machine using the device. Background technique [0002] In the present packaging machinery for household paper towels, especially wet wipes, as a device for sealing the ends and cutting them into bags, the efficiency of knife block processing affects the production efficiency of the entire packaging machinery. Chinese patent CN 202657321 U has published a A full servo reciprocating packaging machine. The up and down reciprocating motion of the upper and lower tool holders of the device and the horizontal reciprocating motion of the tool rest are realized by the positive and negative rotation of the servo motor. In this technology, the servo motor needs to continuously rotate forward and reverse , that is, after the end of the forward rotation, stop and rotate in the reverse di...

Problems solved by technology

[0002] In the present packaging machinery for household paper towels, especially wet wipes, as a device for sealing the ends and cutting them into bags, the efficiency of knife block processing affects the production efficiency of the entire packaging machinery. Chinese patent CN 202657321 U has published a A full servo reciprocating packaging machine. The up and down reciprocating motion of the upper and lower tool holders of the device and the horizontal reciprocating motion of the tool rest are realized by the positive and negative rotation of the servo motor. In this technology, the servo motor needs to continuously rotate forward and reverse , that is, after the end of the forward rotation, stop and rotate in the reverse direction. Because of the inertia of the motor and the relatively laborious reasons from stop to start, the device cannot effectively improve production efficiency, the range of processing speed cannot be further expanded, and it cannot meet the task requirements of high-speed production. In addition, because the servo motor suddenly stops from a constant speed rotation or starts suddenly from a stop, the vibration and noise of the machine are relatively large, and the operation is not stable, and there are hidden safety problems.
