Leveling Shafts for Bulk Package Cross-Section Shaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for leveling packaging filled with bulk or pasty materials only process the underside and fail to evenly distribute the material across the packaging, limiting packing density and efficiency.
Innovation Solution
A device with rotatably mounted leveling shafts and processing units that directly act on the packaging, using rollers, disks, or cams to shape the packaging into an almost rectangular cross-section, combined with lateral leveling belts or rollers to ensure comprehensive processing and even distribution of the material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conveyor belts are used to level packaging, then the packaging can be transported and processed, but the processing is extensive and only affects the underside, failing to evenly distribute material across the packaging
Solution Approach 1:
The packaging processing is divided into multiple independent processing units, each with leveling elements that can be individually adjusted. These units are arranged along the transport direction, allowing different sections of the packaging to be processed separately and comprehensively, not just the underside.
Solution Approach 2:
The leveling elements are arranged not only in the transport direction but also in the vertical and lateral dimensions. This multi-dimensional arrangement allows the leveling elements to contact and process different areas of the packaging from multiple angles, achieving comprehensive material distribution.
2Manufacturing precision
If only the underside of packaging is processed, then the device structure is simple, but the material distribution across the packaging is uneven
Solution Approach 1:
Multiple processing units are arranged along the transport direction, with each unit containing leveling elements that can independently process specific areas of the packaging. This segmentation allows comprehensive coverage of the entire packaging surface through coordinated operation of multiple units.
Solution Approach 2:
The leveling elements are positioned and adjusted before the packaging reaches each processing unit. This preliminary positioning ensures that when the packaging arrives, the leveling elements are already in the optimal position to evenly distribute the material, preventing uneven distribution issues.
3Productivity
If extensive processing is applied to packaging, then more material can be distributed, but packing density and space utilization are limited
Solution Approach 1:
Different processing units are configured with leveling elements suited for specific local requirements of the packaging. This localized optimization allows each unit to precisely control the material distribution in its designated area, achieving uniform packaging shape while maximizing packing density.
Solution Approach 2:
The leveling elements can be adjusted to change processing parameters such as pressure, position, and contact force. By dynamically adjusting these parameters, the system optimizes both the uniformity of packaging shape and the density of material distribution, thereby improving space utilization.
