AI Technical Summary

Technical Problem

Existing carton die-cutting machines have low feeding efficiency, rely on manual operation, and the carton boards are prone to shifting during the conveying process. The limiting mechanism is inconvenient to adjust, making it difficult to meet the needs of large-scale continuous production and affecting the forming accuracy and appearance quality of the carton.

Method used

The system uses an electric push rod to push the cardboard, which, together with the elastic clamping of the feeding roller and the limiting roller, achieves stable conveying. By adjusting the threaded rod and the limiting clamp, it can adapt to cardboard of different widths, ensuring the accuracy of the conveying process and the precision of the die-cutting position.

Benefits of technology

It improves feeding efficiency, reduces manual operation, and ensures that the cardboard is not easily shifted during conveying and die-cutting, thereby improving die-cutting efficiency and quality.

Abstract

This utility model relates to the field of packaging machinery technology, specifically a high-efficiency die-cutting machine for cartons. It includes a strip-shaped worktable with two symmetrically arranged baffles fixedly connected to its upper surface. An ascending platform is also fixedly connected to the upper surface of the worktable. Multiple symmetrically arranged feeding rollers are rotatably connected to the side walls of the two baffles. Each feeding roller has two symmetrically arranged threaded teeth on its surface. A servo motor is fixedly connected to the side wall of the right baffle. This utility model utilizes an electric push rod on the ascending platform to push a push bar, automatically pushing the carton board to the feeding rollers. Combined with the elastic pressing action of the feeding rollers and the limiting rollers, stable and continuous conveying of the carton board is achieved. When the carton board is slightly tilted, the threaded teeth on the feeding rollers will fine-tune the carton board to prevent tilting, reducing manual feeding operations and significantly improving feeding efficiency, thereby increasing the overall die-cutting efficiency.
