Double Wall Paper Cup Combining Mechanism for Twisting Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for producing double wall paper cups face inaccuracies in combining the outer and inner cup parts, often resulting in twisted or incompletely combined cups.
Innovation Solution
An apparatus featuring a cup-combining unit with a pusher and stroker mechanism, which accurately positions and combines the inner and outer cup parts by using a specific slot with a sharp groove to fix the outer cup part and a rotating table system to manage the cup parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional devices are used to produce double wall paper cups, then production can be carried out, but the outer cup part is inaccurately combined with the inner cup part resulting in twisted or incompletely combined cups
Solution Approach 1:
The device is divided into separate functional modules: the first rotation table for holding outer cup parts, the second rotation table for holding inner cup parts, and the cup combining unit with pushers. This segmentation allows each module to perform its specific function independently, improving the precision and reliability of the combination process.
Solution Approach 2:
The pusher acts as an intermediary element that transfers the outer cup part from the first rotation table to the inner cup part on the second rotation table. This intermediary mechanism ensures accurate positioning and combination without direct contact between the rotation tables, preventing twisting and incomplete combination.
2Productivity
If the production speed is increased to meet rising demand, then more double wall paper cups can be produced, but the accuracy of combining outer and inner cup parts may deteriorate
Solution Approach 1:
The dual rotation table system operates continuously with synchronized movement, allowing multiple cup parts to be combined in sequence without stopping. The first and second rotation tables rotate intermittently but continuously maintain the positioning of outer and inner cup parts respectively, enabling high-speed production while maintaining combination accuracy through the continuous operation of the cup combining unit.
3Device complexity
If a simple combining mechanism is used, then the device complexity is reduced, but the ability to accurately position and combine cup parts is compromised
Solution Approach 1:
The invention uses two separate rotation tables arranged in different spatial dimensions (first rotation table for outer cups, second rotation table for inner cups), adding a dimensional aspect to the combining mechanism. This spatial arrangement allows for accurate positioning and combination without requiring complex single-plane mechanisms, balancing device complexity with positioning precision.

AI summary
An apparatus for manufacturing a double wall paper cup is provided. The apparatus includes: a first rotation table configured to rotate intermittently on a horizontal rotating shaft; a plurality of slots for an outer cup part, each of which is installed at intervals of a first predetermined angular value on an outer peripheral surface of the first rotation table; a second rotation table configured to rotate intermittently on a vertical rotating shaft; a stroker configured to move up and down at a combining location; and a cup-combining unit including: (i) a plurality of inner cup part mandrels, each of which is installed at intervals of a second predetermined angular value on a circumference area of an upper surface of the second rotation table; and (ii) a plurality of pushers, each of which has each of pushing shafts capable of moving up and down in directions perpendicular to the ground surface.
