Description

Technical Field

[0001] This utility model relates to packaging equipment, and more particularly to an automatic packaging machine roller gripper gate device. Background Technology

[0002] Patent document CN210453957U discloses an automatic opening and closing gate device for a packaging machine, comprising an upper roller and a lower roller. The two ends of the upper and lower rollers are respectively mounted between two sides of a frame via upper roller bearings and lower roller bearings. The lower roller bearings are slidably mounted in lower roller grooves on both sides of the frame. A vertical drive device is mounted on the frame below the lower roller bearings to drive the lower roller to move up and down. When the machine stops, the vertical drive device automatically moves the lower roller downwards, separating the upper and lower rollers. After restarting, it automatically returns the lower roller to its original position, rejoining the upper roller. This prevents deformation caused by compression at the contact point of the upper and lower rollers after shutdown, ensuring product quality. However, this gate device uses a linear drive structure, resulting in a small opening and closing range and a slow response speed, affecting production efficiency. Therefore, it is necessary to optimize its structure to overcome these shortcomings. Utility Model Content
