Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic capping processes for plastic vacuum forming containers are inefficient and prone to deformation due to inconsistent force application and structural rigidity issues, leading to unstable packaging quality and potential damage during the capping process.
Innovation Solution
An automatic capping machine with a main frame body, positioning part, and workbench featuring a bottom conveyor belt, fixed tracks, and rolling mechanisms that guide the container's convex frame edge for precise capping, ensuring structural rigidity and preventing deformation through an elastic margin and collision avoidance section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an existing rolling mechanism is directly used for automatic capping, then automation is achieved, but the thin-walled container structure deforms or damages due to insufficient structural rigidity
Solution Approach 1:
The patent applies beforehand cushioning by designing a support structure with adjustable support rollers that provide pre-cushioning support to the container body before the capping operation. The support rollers are positioned to contact the container at critical points, creating a cushioning effect that prevents deformation when the capping mechanism applies force. This resolves the contradiction by enabling automation while protecting the thin-walled structure through advance support.
Solution Approach 2:
The patent introduces an intermediary support structure between the container and the capping mechanism. This intermediary system includes adjustable support rollers and positioning devices that mediate the interaction between the automated capping mechanism and the container, distributing forces and preventing direct stress concentration on the thin-walled structure, thus enabling automation without damage.
2Strength
If manual loading and capping is used, then the container structure is safe from deformation, but packaging efficiency and quality stability are insufficient
Solution Approach 1:
The patent applies self-service by designing an automated system where the container itself guides the capping process through its interaction with the fixed tracks and support rollers. The container's own geometry and the pre-positioned support structures work together to ensure proper alignment and force distribution, enabling high-speed automated operation while maintaining structural integrity without requiring complex external control mechanisms.
Solution Approach 2:
The patent replaces the manual mechanical system with an automated mechanical system that uses fixed tracks, conveyor belts, and programmable control. This substitution enables continuous high-speed operation while the support structures and positioning mechanisms ensure that the automated forces are applied correctly to maintain container integrity, thus improving productivity without sacrificing structural safety.
3Ease of operation
If inconsistent force is applied during manual capping, then operation is simple, but packaging quality becomes unstable due to buckle positioning structure requirements
Solution Approach 1:
The patent applies preliminary action by pre-positioning the container on the conveyor belt and using fixed tracks to establish precise alignment before the capping force is applied. The support rollers are pre-adjusted to the correct positions and heights, ensuring that when the capping mechanism engages, the forces are applied at the exact correct locations. This eliminates the variability of manual operation and ensures consistent buckle engagement and packaging quality.
Solution Approach 2:
The patent applies parameter changes by using an adjustable support system where the position, height, and pressure of support rollers can be precisely controlled and standardized. This transforms the variable manual force application into a controlled, repeatable parameter set, ensuring that the capping force is consistently applied with the correct magnitude and direction, thereby achieving stable packaging quality through standardized parameters rather than manual skill.

AI summary
An automatic capping machine for containers includes a main frame body with a workbench having a bottom conveyor belt disposed thereon, and a lining plate provided below the conveying side of the bottom conveyor belt. A fixed track and a rolling mechanism are disposed on the workbench, and there is a gap between the rolling surface of the rolling mechanism and the fixed track. At least one rolling gap is relatively defined and formed by the space between the rolling surface and the fixed track. The lateral state maintaining structure of a container is disposed above the conveying side of the bottom conveyor belt, so that the convex frame edge of the box body of the container is maintained and limited above the fixed track. A through air collision avoidance section is formed in the rolling section defined on the setting path of the lining plate.
