AI Technical Summary

Technical Problem

The existing technology for detecting the moisture content of plastic bottle bricks has the problem of large errors in the whole package, and cannot accurately reflect the uneven moisture distribution inside the plastic bottle bricks.

Method used

An automatic conveyor line is used in combination with a microwave transmitting probe and a microwave receiving probe. The plastic bottle bricks are clamped by moving the gantry and vertical plate along the line. The vertical drive component and reset component of the probe are used to realize continuous scanning and measurement of the microwave probe. Multi-frequency microwaves are used for precise measurement, and the vertical plate squeezes the protruding part to reduce measurement errors.

Benefits of technology

It achieves comprehensive and accurate determination of the moisture distribution inside plastic bottle bricks, reduces measurement errors caused by uneven moisture, and improves the reliability and adaptability of detection.

Abstract

The present invention relates to the technical field of plastic bottle recycling, and more specifically to a device for measuring the moisture content of plastic bottle bricks. The device comprises an automatic conveyor line, a microwave transmitting probe, and a microwave receiving probe. A vertical plate is mounted on a line-moving gantry. When the plastic bottle brick moves between the two vertical plates, the vertical plate clamps onto the side wall of the plastic bottle brick, causing the line-moving gantry to move synchronously with the plastic bottle brick. A probe vertical drive assembly is fixedly mounted on the side wall of the vertical plate and is used to drive the microwave transmitting probe and the microwave receiving probe to move up and down. After the line-moving gantry moves along with the plastic bottle brick for a measured width, a reset assembly drives the line-moving gantry to move in the opposite direction of the conveying direction of the automatic conveyor line. In the present invention, the vertical plate clamps onto the side wall of the plastic bottle brick, allowing the microwave transmitting probe and the microwave receiving probe to scan back and forth close to the side wall of the plastic bottle brick, thereby reducing errors in measuring the moisture content of the entire package.
