The Motion Characteristics Analysis and Simulation of the Transverse Sealing Mechanism in a Pillow Bag Packaging Machine

摘要

Aiming at the problem of realizing the high-speed continuous packaging of the pillow bag packaging machine, a double crank type transverse sealing mechanism was proposed, and its dynamic characteristics were analyzed. According to the technical requirements of the transverse sealing mechanism of the packaging machine, the driving law of the servo motor in the horizontal direction and the vertical direction were designed, and the driving speed and acceleration equations of the servo motor were obtained. The kinematics simulation of the transverse sealing device was carried out by using kinematics equations as some servo input in the dynamics software. The results show that it is a better way to accurately calculate the time of each phase of the transverse sealing mechanism during one cycle in order to meet the design requirements of the smooth and rapid operation, by means of obtaining the motion of the Z-direction which is determined the motion function of the X-direction of the transverse sealing mechanism. It can realize long-term stable high-speed continuous packaging. In view of the fact that the crank mechanism of the curve design can also be better applied to other transverse sealing mechanisms under the rush condition, the motion principle is worthy of promotion.
