Width-Adjustable Packaging Bag Shaper with Leadscrew Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current noodle packaging machines are limited in their ability to adjust packaging bag widths according to the weight of noodles, leading to reduced production efficiency and increased costs, as existing shapers can only manufacture single-sized bags and lack adaptability in material stress management.
Innovation Solution
A width-adjustable packaging bag shaper system featuring a novel shaper design with a guide surface and side wings that allow for adjustable width, utilizing a leadscrew and slide block mechanism for precise width adjustment, and a control system incorporating a stepper motor and single-chip microcomputer for automated operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional shapers (lapel, triangle, trunk-like, U-shaped) are used, then the packaging bag can be formed, but the width cannot be adjusted to accommodate different noodle weights
Solution Approach 1:
The shaper is divided into multiple adjustable components including left and right guide surfaces, side wings, and modular sections that can be independently positioned. This segmentation allows the width to be adjusted by reconfiguring the relative positions of these segments without redesigning the entire shaper structure.
Solution Approach 2:
The shaper incorporates adjustable and movable components rather than fixed structures. The guide surfaces and side wings can be dynamically repositioned to change the bag width, transforming a static single-function device into a dynamic multi-configuration device that adapts to different packaging requirements.
2Productivity
If fixed-width shapers are used, then the structure is simple, but the production efficiency decreases when different bag widths are needed
Solution Approach 1:
The shaper uses adjustable components with quick-change mechanisms that allow rapid reconfiguration between different widths. This dynamic capability enables the system to maintain high productivity by minimizing the time required to switch between different bag specifications.
Solution Approach 2:
The shaper allows modification of geometric parameters (width, angle, position) through adjustable components. By changing these parameters rather than replacing entire components, the system achieves versatility while controlling complexity through standardized adjustment mechanisms.
3Ease of repair
If complex shaper designs are used, then the shaping function is effective, but the maintenance and debugging become difficult
Solution Approach 1:
The shaper is designed as a modular system with distinct, separable components (guide surfaces, side wings, support structures) that can be independently accessed, inspected, and maintained. This segmentation simplifies troubleshooting and repair by isolating potential problem areas to specific modules rather than requiring disassembly of a monolithic structure.
Solution Approach 2:
The adjustable components are designed with user-friendly adjustment mechanisms that allow operators to perform basic maintenance and reconfiguration without specialized tools or extensive technical knowledge, enabling self-service maintenance for routine operations.

AI summary
A width-adjustable packaging bag shaper, a bag maker, a packaging machine, and a method. The packaging machine including the bag maker, a traction device and a heat sealing device are respectively arranged above the bag maker, and a width adjustment device adjusts the distances between different sub bottom plates in a front bottom plate and a rear bottom plate by using a leadscrew and slide block mechanism, and then adjusts the width of a bottom plate. The leadscrew and slide block mechanism is used as the width adjustment device of the automatic width-adjustable noodle packaging bag shaper system, and four bottom plates are respectively fixed to the width adjustment device, so the leadscrew and slide block mechanism in operation is accurate in range of adjustment, is suitable for various widths of packaging bags, and has very important significance for the three-dimensional shaping effect of the packaging bags.
