One-side gripper-bar-free intermittent motion mechanism and mold pressing technology thereof

Abstract

The invention discloses a one-side gripper-bar-free intermittent motion mechanism and a mold pressing technology of the one-side gripper-bar-free intermittent motion mechanism. The mechanism comprises a servo motion control system, a servo motor, a driving chain wheel, a driven chain wheel, a chain, paper grippers and a photoelectric detection switch. The servo motion control system, the servo motor and the driving chain wheel are arranged on a wall plate of a machine frame. The chain is connected to the driving chain wheel and the driven chain wheel. The multiple paper grippers are fixed to the chain. The photoelectric detection switch is arranged on one side of a fixed platform. A gripper bar is omitted, the paper gripping operation way that the paper grippers are directly fixed to one chain is adopted, and therefore the equipment structure is optimized and simpler. Meanwhile, the servo motor and the servo motion control system are adopted and matched with the photoelectric detection switch, the operation control precision and detection position precision of the mechanism are far higher than the motion control precision and the positioning precision of a mechanical intermittent motion mechanism in the background art, the operation speed and production efficiency of equipment are improved, the die cutting processing precision and the yield of paper are improved, and the cost of the complete machine is saved.

[0002] Printing and packaging machinery occupies an important position in the development of the national economy, and the flat die-cutting machine of post-press equipment is one of the main printing and packaging machinery. It is an important part of the paper, which is responsible for the task of completing a series of processing procedures such as paper conveying, creasing, die-cutting, hot stamping, etc. in the way of intermittent operation, and determines the process quality of the processed paper products. The existing equipment The gripper row transmission mechanism adopts a mechanical intermittent transmission mechanism. More than 5 gripper rows are fixed on the double chain of the mechanism. Each gripper row is composed of gripper row body, gripper teeth and other components. Composition, because the gripper row needs to be fixed on two parallel chains, and the mechanical intermittent transmission mechanism is adopted, which greatly increases the load and motion inertia of the intermittent transmission mechanism, restricts the machine speed, not only cannot improve production efficiency, It also caused the position error of the intermittent movement of the gripper row to be too large, thus affecting the processing accuracy and yield of die-cut paper products
