AI Technical Summary

Technical Problem

Existing fertilizer packaging machines suffer from poor sealing, leading to dust leakage and environmental pollution, and the lack of precise control over the feeding mechanism results in inaccurate metering.

Method used

The measuring cylinder and the feeding cylinder are connected by a sliding insertion mechanism. Combined with the meshing design of the half gear and the drive gear, the height of the measuring cylinder is raised and lowered by the drive motor through the adjusting screw and the threaded tube block linkage ring tube. Combined with the hinge rod and the ball bearing sliding control of the opening and closing of the sealing cover, the measuring cylinder can achieve accurate metering and prevent leakage.

Benefits of technology

It achieves precise control of fertilizer quantity, avoids dust leakage and quantitative deviation, improves packaging efficiency and equipment reliability, reduces electrical failure points, and extends equipment life.

Abstract

This utility model belongs to the field of fertilizer quantitative packaging technology, and in particular, an automatic quantitative packaging machine for fertilizer production. It includes a CNC packing machine, with a feeding hopper fixedly connected to the upper surface of the CNC packing machine via beams and beam plates. The shell of the CNC packing machine is also equipped with a conical pipe for conveying and packaging quantitative fertilizer. A quantitative feeding mechanism is provided on the lower surface of the feeding hopper, including a measuring cylinder. The volume of the quantitative fertilizer is adjusted by adjusting the height of the measuring cylinder. This automatic quantitative packaging machine for fertilizer production uses a drive motor to drive an adjusting screw and a threaded tube block to raise and lower the ring tube, thereby adjusting the height of the measuring cylinder and accurately adjusting its volume. This adapts to the quantitative requirements of fertilizers with different densities and particle sizes, solving the packaging deviation problem of traditional fixed-volume measuring cylinders. Combined with the meshing design of the half-gear and drive gear, it ensures precise synchronization between the filling and feeding processes of the measuring cylinder, avoiding fertilizer leakage or inaccurate metering caused by continuous rotation.
