Nested Suction Nozzle Structure for Compact Flow Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction nozzle devices require multiple nozzles with different diameters, increasing device size and weight, making them difficult to maneuver quickly and limiting their ability to optimize flow rates for varying workpiece sizes.
Innovation Solution
A suction nozzle device with a large-diameter and small-diameter pipe structure, where the small-diameter pipe moves relative to the large-diameter pipe, allowing the flow path cross-sectional area to be adjusted continuously between the inner diameters of both nozzles, optimizing suction force and enabling faster operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple suction nozzles with different diameters are attached to a rotary disk, then the suction nozzle can be switched to match different workpiece sizes, but the overall device size increases and it becomes difficult to insert the nozzle into narrow spaces
Solution Approach 1:
The patent applies nesting by placing the small-diameter pipe inside the large-diameter pipe, allowing both nozzles to be contained within a compact structure. The small-diameter pipe can move axially to selectively protrude from or retract into the large-diameter pipe, enabling nozzle diameter switching without requiring multiple separate nozzles or a rotary disk mechanism.
2Adaptability or versatility
If multiple suction nozzles are attached to a rotary disk with rotation mechanism, then different nozzle diameters can be selected, but the device weight increases and high-speed movement becomes difficult
Solution Approach 1:
The nested pipe structure eliminates the need for a rotary disk and rotation mechanism. Instead of mounting multiple nozzles on a rotating platform, the invention uses one nozzle (small-diameter) that can extend from or retract into another nozzle (large-diameter), significantly reducing the weight of moving parts while maintaining the ability to switch between different effective nozzle diameters.
3Device complexity
If the flow path cross-sectional area is fixed to the inner diameter cross-sectional area of the smallest diameter nozzle, then the device structure is simplified, but it becomes difficult to optimize the flow rate in accordance with the weight of the workpiece
Solution Approach 1:
The patent implements a dynamic flow path structure where the small-diameter pipe can move axially relative to the large-diameter pipe. This allows the effective flow path cross-sectional area to be dynamically adjusted by changing which nozzle protrudes and by what amount, enabling optimization of suction flow rate for different workpiece weights while maintaining relatively simple device structure.

AI summary
A suction nozzle device includes a large-diameter pipe, a large-diameter nozzle, a small-diameter pipe, a small-diameter nozzle, and a support mechanism for supporting the large-diameter and small-diameter pipes so as to be movable relative to each other. As the large-diameter and the small-diameter pipes move relative to each other, the large-diameter nozzle and the small-diameter nozzle selectively protrude. A nozzle can be selected from nozzles having different diameters, and the flow rate can be varied in accordance with the selection of the nozzle.
